Title: Improvements in or relating to the Line-measuring and Indicating Mechanism of Typographic Composing Machines.
IPC: B41B25/00
Filed: 1917-05-25
Abstract: 108,465. Lanston Monotype Corporation, (Lanston Monotype Machine Co.). May 25, 1917. Addition to 105,620. Strip-perforating machines; justifying-type; keyboards.-The arrangement described in the parent Specification is improved by providing means for rendering the entire justification-indicating mechanism inactive when the repeating- mechanism is in action. As shown, the repeating- mechanism is constructed in the manner described in Specification 100,668 and the justification-indicator is operated as described in Specification 110,773 by a pneumatic motor 25 which causes a rack geared to the indicator to follow up an abutment slide which is advanced by the units-wheel rack 6 and is resisted by the buffering-motor 12, the motors 12 and 25 being connected by a pipe 28. According to the invention, the catch 28<a> for holding up the repeat-bar 19<a> is provided with a pin 45<a> which engages a depending arm on a valve bar 50 controlling a valve 51 for normally admitting air from the chamber 161 to a pipe 117 leading to the motor 12. When the repeat-key 15<a> is depressed, the catch 28<a> is rocked on the axis 30<a> and releases the repeat-bar and also the bar 50, thus permitting the valve 51 to close and cause the pipe 117 to communicate with the atmosphere instead of the chamber 161. During the time that the repeating-mechanism is being operated, the motor 25 for advancing the justification-indicator is inoperative and the buffering-motor 12 offers no resistance to the line-measuring mechanism. In a modification, the valve 51 is pushed inwards when the catch 28<a> is rocked. Specifications 17199/08 and 27264/13 also are referred to.

Patent GB-669462-A (GB)
Title: Improvements in or relating to equipment for use with electrical resistence strain gauges
Inventor: AUGHTIE FRANK
IPC: G01L1/22
Filed: 1946-03-12
Abstract: 669,462. Electrical strain gauges. NATIONAL RESEARCH DEVELOPMENT CORPORATION. April 12, 1947 [March 12, 1946], No. 7679/46. Addition to 586,268. Class 37. The parent Specification describes a bridgeconnected electrical strain gauge having a calibrating resistance for passing a current, corresponding to a specified strain, through the galvanometer and an additional network for rendering the calibration unaffected by the initial balancing adjustment of the bridge. In the present Specification a further network, connected to the calibrating resistance, permits that resistance to be of a much lower value than that used in the former case. In one embodiment the calibrating resistance R37 is connected through a switch S to the point of connection of two resistances R41, R42 which bridge the battery B7, and which are so chosen that the potential drop across R37 is considerably reduced, e.g. onehundredth of battery voltage. The calibrating resistance is made correspondingly low in order that the correct calibrating current may pass through the galvanometer. A series of settings may be obtained by connecting the resistance R37 through a selecting switch to one of a number of tapping points on the potentiomater across the battery. The Specification also discusses mathematically the possibility of reduction of error in calibration for different positions of the slider and deduces that the ideal distribution of potential along the slide wire is parabolic. For practical purposes a reasonable approximation is obtained by two tappings to the ends of the middle section R23, as in the Figure, but greater accuracy is obtained by additional tappings through resistances of suitable value, see Fig. 8, not shown.
