Abstract: A digital multimeter having automatic function selection capability includes a signal type detector and an analog-to-digital converter formed as an application specific integrated circuit. The signal type detector has a comparator circuit that compares the analog input signal to be measured with predetermined thresholds and stores the resulting values, which are related to the type of analog input signal, in a memory that is also a part of the signal type detector. A controller executes an automatic function selection program that causes the controller to read the stored values and generate a corresponding function code, which causes an analog-to-digital converter to be configured to perform an appropriate conversion function on the analog input signal. When a change in the type of analog input signal is sensed, the controller aborts the present measurement cycle and proceeds with a next measurement cycle in which the changed analog input signal is measured. The controller also produces a change alert signal to indicate that a change in signal type has occurred. Claim: A method for causing a digital multimeter to automatically select appropriate measurement functions for different types of analog signals appearing at the input terminal of the multimeter, said method comprising the steps of: (a) detecting the analog input signal; (b) producing first data representative of the type of analog input signal to be measured when said analog input signal is an AC signal; (c) producing second data representative of the type of said analog input signal to be measured when said analog input signal is a DC signal; (d) generating function code corresponding to one of said first and second data; (e) using said function code to cause an analog-to-digital converter to be configured to perform an appropriate conversion function on the analog input signal to be measured; and (f) producing a display indicative of said analog input signal.

US Patent: 2,521,011 https://www.datamp.org/patents/displayPatent.php?id=85324&pn=2,521,011 Cam operated jar cap wrench Patentee: Nathan D. Hoskins - Parsons TN Granted:1950-09-05
Manufactured by Hoskins Products Co. - Jackson TN

An object of my invention is to provide a tool of this character which can be used with equal facility to apply or screw on and to loosen or screw off, the screw tops or caps of "Mason" or other screw-topped jars, and which is of such construction that it is readily applied to and removed from the jar top or cap, and with which the force employed to move and turn the jar top will tighten the wrench and assure a firm grip of the tool upon the top or cap, for both tightening the screw cap into place and removing the same." The informant supplying the data for this entry explained that Hoskins Mfg. Co. changed name to Hoskins Products to differentiate from another Hoskins Mfg. in Missouri.

US Patent: 2,240,410 https://www.datamp.org/patents/displayPatent.php?id=42369&pn=2,240,410 Paring Knife Patentee: James A. Murdock - Chicago IL Granted:1941-04-29
Manufactured by EKCO Products Co. - Chicago IL

The specifications claim the parallel facing cutting surfaces, and the blade extending from the handle. An example marked A&J MADE IN U.S.A. PAT NO. 2240410 is nearly identical in physical appearance to a parer marked EKCO NEE ACTION PAT NO. 2232940. The blade and handle also appear in a parer marked NEE ACTION U.S.A. PAT. Nos. 2220169 2240410.

US Patent: 2,220,169 https://www.datamp.org/patents/displayPatent.php?id=42370&pn=2,220,169 Kitchen Utensil and Method of Mounting Blades Patentee: James A. Murdock - Chicago IL Granted:1940-11-05
Manufactured by EKCO Products Co. - Chicago IL

The utensil has a parer blade, and parallel thin slicing blades. The patent describes the assembly of the thin slicing blade portion in some detail. Known example marked U.S.A. PAT. Nos. 2220169 2240410 NEE ACTION. The parer blade and handle also resemble pat. no. 2232940.

US Patent: 6,125,722 https://www.datamp.org/patents/displayPatent.php?id=28260&pn=6,125,722 Ratchet Wrench with Sealed Reversing Lever Patentees: Richard L. Hopper Jr. - Kenosha WI , William A. Nurmi - Racine WI , Charles H. Heiligenthal - Kenosha WI , Kenneth E. Kessler - Albion IL Granted:2000-10-03
Manufactured by Snap-On Tools Co. - Kenosha WI

Seyfarth Shaw - patent attorney Improvement to the ratchet in 4,934,220. The patent number is reported on a WILLIAMS branded ratchet; Snap-On acquired WILLIAMS ca. 1994. Abstract A reversible ratchet wrench has a ratchet body with a cavity receiving the ratchet assembly. A pawl-engaging reversing lever is insertable through an opening in the ratchet body from the cavity and has a flange dimensioned to be trapped between the body and the pawl. A seal between the reversing lever and the ratchet body is provided by an O-ring seated in a groove in the outer surface of the reversing lever hub. A cover plate closes the cavity and cooperates with the pawl and the flange to retain the reversing lever in place.
