Title: Improvements in tools for crimping electrical connectors to electrical conductors
IPC: H01R43/042
Filed: 1960-03-29
Abstract: 882,796. Stamping; shearing; bending. AMP Inc. March 29, 1960 [April 13, 1959; May 19, 1959; Aug. 18, 1959], No. 11032/60. Class 83 (4). [Also in Group XXI] In a tool for operating on a workpiece positioned between a fixed die 26 and a movable die 28 the fixed die is carried on a frame 20 and the movable die 28 is connected to a ram 30 having a detonating pin 70, the ram 30 being driven by springs 64, Fig. 5 (not shown), down a breech 32 against a primer 10 to detonate an explosive charge 6 for forcing the die 28 on its working stroke. The charge 6 is located between a plug 8 containing the primer 10 and the closed end of a polyethylene cylinder 2 which is inserted in the breech 32 and which protects the breech against the explosive gases which remain sealed in the cylinder. The firing stroke of the ram 30 is triggered by depressing a spring-loaded safety pin 52 while simultaneously gripping a handle 22 to depress a lever 40 against a spring 48, the lever 40 pivoting about a pin 46 and releasing an arm 42 from a recess 50 in the spring-loaded moving dieblock. As an additional safety measure an arm 44 will not enter keyways 36, 38 unless the breech cap 34 is fully screwed on. The invention is applied to the crimping of an electrical connector C on a conductor W but is also applicable to cable cutting and other metal forming operations. In a modification, Fig. 10, the connector C and wire W are held prior to crimping against the die 26 by the hooked end 80 of a spring 78 which is tensioned by rotation of discs 72. The breech cap 34 is pivoted on a mounting ring 88 to which it is locked by a spring-loaded lever 84. The tool is triggered by drawing back a hollow rod 90 in the direction of the arrow against the tension of a spring 114 attached at one end to the inside of the hollow rod and at the other to a lever 100 pivoted on a pin 104. On engagement of a tab 116 attached to the rod 90 with a spring- loaded pivoted catch 102, the catch rotates about a pin 106 and disengages from a stop 110 on the die 28 releasing the latter so that the ram 30 is forced into the cartridge cylinder by the spring-loaded lever 100 to initiate firing. In another modification, Fig. 13, the ram 30 is made hollow to prevent a cushioning effect by the air in the cartridge cylinder on the firing stroke, the firing pin 70 being mounted in close contact with the primer on the end of a sleeve 117. The trigger mechanism is similar to that of the tool of Fig. 10 except that the rod 90 is replaced by a bar 118 pressed back against the spring 114 by a trigger 122. To fire the tool the trigger 122 is pulled downwards to clear the stop pin 130, and rotated to push back the bar 118, the ram 30 being operated as before. On release the trigger 122 automatically returns to the position of Fig. 13. A spring-loaded lever 142 operates a modified holder 132 for the wire W through a linkage, Fig. 12 (not shown). Specifications 872,626 and 873,192 are referred to.

Title: An improved method of telemetering the quotient of two measured magnitudes
IPC: G08C19/26
Filed: 1933-04-13
Abstract: 403,270. Electric signalling systems. LANDIS & GYR AKT.-GES., 1, Hofstrasse, Zug, Switzerland. April 13, 1933, No. 11048. Convention date, July 1, 1932. [Class 40 (i).] In a system for indicating the quotient of two measured quantities, two series of impulses, the frequencies of which are proportional to the measured quantities, are separately transmitted to a receiving station and are converted into currents for operating a quotient meter. As shown in Fig. 1, in which the system is adapted for indicating power factor, meters 1, 2, measuring true and apparent powers respectively, transmit impulses over line wires 3, 3<1> to operate receiving relays 6, 7, the contacts of which control the charging and discharging of pairs of condensers 8, 81, 9, 9<1> connected in circuit with the coils 10, 11 of a quotient meter 12. The currents in the coils 10, 11 are proportional to the frequencies of the impulses transmitted over the corresponding line circuits. In a modification, the condensers are replaced by resistances which are varied in accordance with the rate of impulsing. Fig. 3 shows a system employing, in addition to the quotient indicator 12, instruments 19, 20 arranged to indicate the individual quantities. Resistances 13, 14 associated with the quotient meter are regulated in accordance with the frequencies of the incoming impulses. The instruments 19, 20 are provided with resistances 23, 24 which are controlled by the impulses transmitted from the associated transmitters. The resistances 23, 24 may be dispensed with by connecting the coils, 11<1>, 10<11> in series with the coils 11, 10 of the quotient meter. Specification 382,526 is referred to.

Patent GB-541386-A (GB)
Title: Improvements in and relating to apparatus for gas analysis
IPC: G01N27/16
Filed: 1940-07-01
Abstract: 541,386. Testing gases. BRITISH THOMSONHOUSTON CO., Ltd. July 1, 1940, No. 11090. Convention date, July 1, 1939. [Class 1 (i)] Apparatus for determining the amount of one component of a gaseous mixture consists of a metal strip which reacts with that component; the strip is heated non-uniformly and the relative amount of it which has reacted with the gas is measured. The apparatus can be used for measuring the portion of oxygen in the exit gases from boilers in controlling combustion and, with a different metal, for measuring percentages of hydrogen in hydrogen atmospheres. A form of metal strip 11 is shown in Fig. 4, and for oxygen estimation is made of material, such as palladium, which has an equilibrium reaction with oxygen varying according to temperature. The strip is tapered as shown and is heated by the passage of a current through it; the taper causes a suitable temperature gradient. At the higher temperature of the top end of the strip, the oxygen and palladium are dissociated and the palladium remains bright, while at the lower temperatures of the bottom end and the palladium becomes darkened by oxidation. The oxidized part a<SP>11</SP> of the strip reaches a point 13 which indicates the equilibrium temperature for the percentage strength of oxygen in the mixture, and a calibrated scale can be placed at the side of the strip to give a direct reading. An iron strip can be used in a similar way to indicate the composition of mixtures of water vapour or steam and hydrogen. Instead of a strip, a disc may be employed, with an electric heater at its centre, thereby producing an oxide ring varying with the gas composition. The bright area at the centre may be measured by means of a photo-cell. In another form of apparatus the palladium strips 27, 28 are tapered towards the centre and form opposite arms of a Wheatstone bridge with strips 25, 26 of platinum or like inert material These are mounted in the tube 31 through which the gas mixture passes. Current is supplied to opposite junctions of the bridge to heat the arms, and the open ends are joined by a resistance 37, and an instrument 39 receives any out-of-balance current. The variations in the bright and dark portions of the palladium due to variations in oxygen content of the gas, cause variations in the radiation from the strips and consequently the temperatures and resistances. The current through the instrument 39 therefore depends on the oxygen content. In another form of apparatus a bimetallic strip is employed and its bending is a measure of the oxygen content.

Title: Improvements in electric trip switch devices
IPC: B61L3/10
Filed: 1923-04-24
Abstract: 214,829. Waller, P. H. April 24, 1923. Retractive switches; retarding devices.-A trip switch for indicating, recording and registering operated for a short time by an obstruction during the passage of a travelling unit comprises actuating mechanism which, when struck by the travelling unit, for example a trolly wheel, drives the contact-member into the closed position where it is held for a time, by clockwise mechanism against the return action of a spring strained by the return movement of the actuating mechanism, until released to open rapidly. As shown applied to a fixed switch operated by a travelling trolly wheel 25. the wheel strikes the trip arm 1 which drives the plunger rod 9 and its compression spring casing 6 as a unit thereby driving the contact arm 15 to the closed position. At the same time, the latch 17 pivoted on the plunger and connected therewith by the spring 19 is driven, guided at its lowerend by the guide rod 21, into engagement with the clockwork train 26, the reduced end of the guide rod permitting the final engaging movement. The trip arm after actuation returns under its own weight and impresses the spring 24, and when, in course of time, the clockwork train revolves sufficiently to release the latch 17 the plunger is drawn back rapidly to its original position thereby opening the switch rapidly. The trip device may be carried on the vehicle and be operated by a stationary ramp.
