Title: Improvements in Hand-punches.
Inventor: BRIMBERG SAMUEL NATHAN
IPC: B21D28/24
Filed: 1919-03-25
Abstract: 128,539. Brimberg, S N., (Assignee of Rosenberg, H.). June 19, 1918, [Convention date]. Pliers &c.-In a hand-punch which utilizes the toggle principle to obtain a high mechanical advantage, the punching-tool can readily be withdrawn from the head of the instrument. The work is inserted between the die 13 and a punching-tool held in the carrier 21 which slides vertically in a recess 14. The carrier 21 is pivoted at 22 to the upper lever 17, and the latter is connected to the lower lever 11 by side-links 16 so that a toggle action is obtained. A limiting-device to prevent the levers from opening too widely comprises a lug 25 on the punch-carrier 21 which engages a lug 27 on a bolt 26. To enable the punching-tool to be withdrawn when desired, the bolt 26 is made rotatable and a recess 24 is cut away. The tool can thus be withdrawn by a movement of the lever 17 opposite to its operative movement.

Patent GB-384865-A (GB)
Title: An improved method of and apparatus for telemetering
IPC: G08C19/02
Filed: 1932-03-14
Abstract: 384,865. Electric signalling systems. LANDIS & GYR AKT.-GES., 1, Hofstrasse, Zug, Switzerland.. March 14, 1932, No. 7511. Convention date, March 18,1931. [Class 40 (i).] In a system of remote indication of measured magnitudes of the type wherein the indication is determined according to the frequency of transmitted impulses, the impulses are converted into impulses of constant length which produce a quantitative heating effect upon a heat-responsive measuring system. As shown in Fig. 1, a commutator 3 on the shaft of a measuring instrument a transmits impulses at a rate proportional to the magnitude being measured over line wires 2 to operate the electromagnet 1 of a ratchet mechanism 6, 7. The wheel 7 drives a gear wheel 10 which co-operates with a wheel 11 gearing with a pinion 18 carried on a bracket 13 which is loosely mounted on the shaft 12. The pinion 18 carries a contact disc 19 co-operating with contacts 20, 21 in the circuit of the indicating instrument d and also a fly 17 which normally engages a stop-pin 16. Upon the receipt of an impulse, wheel 11 is rotated and due to the interengagement of fly 17 and stop 16 the bracket 13, together with wheel 18, is rotated anticlockwise until when the fly 17 escapes the stop 16, the wheel 18 rolls down the now stationary wheel 11 into its original position. During restoration of the wheel 18, the circuit 22 is closed for a predetermined time to cause heating of the bimetallic strip of the instrument d. In this manner impulses in the circuit which may be of irregular time duration are repeated in circuit 22 in the form of impulses at similar frequency but of uniform time duration. Instead of the converting apparatus shown a Ferraris motor, which makes one revolution after each received impulse, may be employed. In a modification, the received impulses act through an accumulator spring on an electromagnetically braked eddy-current disc which drives a contact disc in circuit with a heating element which affects a thermoelement connected in circuit with an indicating instrument. The heating and thermo elements are enclosed in an evacuated glass vessel. The indications of a plurality of measuring apparatus may be summed either by transmitting the impulses of the several apparatus to a totalizing mechanism which controls the contact disc in the indicating circuit or by providing individual impulse converting apparatus which control corresponding heating coils arranged on the bimetallic strip of the indicating .instrument.

Title: Linear polythioesters
IPC: C08G75/26
Filed: 1947-03-19
Abstract: Polythioesters are prepared by heating a mixture of approximately equimolecular proportions of an acid chloride ClOCRCOCl, and a dimercaptan HS-R1-SH.  R and R1 are divalent hydrocarbon, oxahydrocarbon or thiahydrocarbon radicals and the functional groups are attached to different carbon atoms in the radicals.  Dimercaptans mentioned are ethylene, trimethylene, tetramethylene hexamethylene and decamethylene; 3-oxa-1,5-dimercaptopentane, 3,6-dioxa-1,8-dimercaptooctane, 4-oxa-1,7-dimercaptoheptane, 3-thia-1,5-dimercaptopentane, 4-thia-1.7-dimercaptoheptane, and mercaptans having the formul  <FORM:0630625/IV (a)/1> Suitable acid chlorides mentioned are those in which R is ethylene, 1,2-prolylene, trimethylene, tetramethylene, hexamethylene, octamethylene, decamethylene, o-, m- or p-phenylene, naphthylene, xylylene, diphenylene, dinaphthylene, 3-oxapentamethylene, and 3-thiapentamethylene.  Preferably there is a chain of at least 4 atoms between the mercapto groups and of at least 3 atoms between the acid chloride groups.  Reaction is preferably performed in absence of oxygen, e.g. with a stream of nitrogen passing through the mixture. The acid chloride may be added in portions or continuously throughout the reaction. Vacuum may be applied.  The course of the reaction may be followed by the melt viscosity of the product.  Generally a slight excess of dimercaptan (not more than 2 per cent over equimolecular) may be used.  Extra reagent may be added to compensate for losses by volatilization.  The reactants may be mixed at about 0 DEG  C. and warmed to initiate reaction and to produce a homogeneous reaction mixture.  Cooling may then be necessary, and finally heating to 200 DEG  C. or more after a solid polymer has been formed. Interpolymers may be formed by using more than one of either or both kinds of reagent.  The products are particularly useful for fibre production, but may also be used for moulding, or for coating or insulating compositions.  Examples describe production of polymers from (1) sebacyl chloride and hexamethylene dimercaptan; (2) terephthalyl chloride and pentamethylene dimercaptan; (3) adipyl chloride and p-xylylene dimercaptan.  A table is also given showing the physical properties of a number of other polythioesters from different combinations of reagent.
