Title: Improvements in or relating to two-part couplings or connectors for electric cables
IPC: H01R13/20
Filed: 1952-09-02
Abstract: 736,091. Two-part couplings. TUCHEL, U. Sept. 2, 1952 [March 5, 1952], No. 22089/52. Class 38 (1). A two-part cable connector particularly for use in mines, comprises a plug having two parts (Figs. 1 and 2), the first consisting of an insulating body 14 with an integral pin 2 on which are two pairs of contact blades 15, 16, 'and ribs 11 of quadrantal cross-section on the body 14 which are formed with bores 18 containing springs 19. The second part is a sleeve 1 which fits over the pin 2 and has quadrantal guide parts fitting the ribs 11 and locating pins 9 entering the bores 18. A pair of slotted split contact sleeves 7 engage the contact blades 15 when the coupling parts are separated. The socket half of the coupling comprises an insulating sleeve 20 having two pairs of slotted contact sleeves 29, 26 and a sliding element 21 with four blade contacts 22 interconnected in pairs. The element 21 is held in position by loose claws 23 which engage the wall of the sleeve 20 and the element 21 respectively. The cables to be connected are attached to terminals 17, 28 in contact with blades 16 and sleeves 29, respectively, and the socket half is then pushed over the pin 2 moving the sleeve 1 against the springs 19 until the contacts 7 bridge the blades 15, 16. The pin 2 meanwhile causes the slide 21 to disengage the claws from recesses 35 in the sleeve 20 and moves the slide downwards, each pair of blades 22 then bridging sleeves 29 and 26. The latter now engage the contact blades 15, thus completing the connection, the claws engaging recesses 27 in the pin 2. When separating the coupling parts the claws hold the element 21 against the pin 2 until the heads 31 thereof can enter the recesses 35. The plug part is surrounded by a metal casing 33, the connection being therefore only completed when all the " live " parts are completely enclosed. The halves of the coupling are held together by a bayonet connection, or threaded sleeves.

Abstract: 459,654. Face-mills for gear cutting. GLEASON WORKS, 1000, University Avenue, Rochester, New York, U.S.A. Aug. 11, 1936, No. 22122. Convention date, March 30. [Class 83 (iii)] A rotary face-mill cutter particularly for cutting curved tooth bevel and hypoid gears which have been previously roughed out has a number of preliminary cutting blades 101 ... 114 and two finishing blades 115, 116 each of which takes a full-depth cut on one side of a tooth space so as gradually to widen the space to full width. The cutter finishes a blank without axial feed and without generating motion between cutter and blank. The finishing blades are followed by a gap G which passes the gear while the latter is indexed to cut the next tooth. Preferably successive blades act on opposite sides of the tooth space, the odd numbered blades 101 .. 115 acting on one side and the even numbers on the other side, successive cuts being shown in Fig. 4. The finishing blades take only a very light cut and are separated from the remaining blades as shown in Fig. 1 so that no other cut is taken while a finishing blade is in operation. The usual relief is provided. The body 11 may be cut away at the gap G so that the work piece may be removed and a fresh blank positioned without relative withdrawal of blank and cutter. The blades may be of different shapes to provide the desired radial dispositions of the cutting edges but preferably all the tapered blade seats 15 are at the same radial distance from the cutter axis and the blade is located against a block 17, Fig. 3, which bears against a wedge 16 which. is complementary to the tapered seat 15 and provides a fine adjustment by means of a screw 19. A screw 18 clamps the blade assembly to a slot in the body. The edges 16 are of different thicknesses for different blades. The wedges of the finishing blades are preferably locked in position by pins 25 and are non-adjustable.

Filed: 1962-06-12
Abstract: 1,013,813. Regulating. CUMMINS ENGINE CO. Inc. June 12, 1962, No. 22473/62. Heading FIB. Fuel delivered by a pump 32, Fig. 1, to fuel injectors 27 is controlled by a speed responsive valve 44 which has associated therewith a valve 71 controlling a by-pass for the fuel back to the pump inlet. The valve 44 is controlled by a centrifugal governor 81 and has a main control passage 63 controlling the main delivery passage 47 and an idling groove 101 controlling the supply to idling passage 93, the passages 47, 93 being further controlled by a manual throttle valve 49. The by-pass valve 71 controls a by-pass passage 65 in the plunger 44 towards the end of which it is urged by idling springs 73, 74, and a main spring 78. At idling, Fig. 9, the groove 101 connects the idling parts 97, 98, and the main passage 47 is closed by the throttle 49, if the speed begins to exceed idling, the passage 63 opens port 59 to by-pass fuel through the valve 71 to keep the idling speed constant. During normal running the main passage 47 is open and the valve 44 opens the main port 61, the amount and passage of the fuel by-passed being controlled by the valve 71 loaded by spring 78 according to the position of the plunger 44. At maximum desired speed the plunger 44 closes port 61 but maintains port 59 open to permit the fuel delivered thereto to be bypassed back to the pump. During the normal running range a subsidiary spring 86 varies the characteristic of the governor 81. The manual throttle valve 49 may contain a throttling plunger 228, Fig. 15, of a substance e.g. nylon, which has a greater coefficient of expansion than the metal valve body 220. The plunger 228 restricts the main flow bore 221 at low temperature and expands to reduce the restriction to connect the supply at higher temperature, the idling bore 222 remaining constricted.

Abstract: 1380148 Telegraph exchanges COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS CIT-ALCATEL 15 May 1972 [14 May 1971] 22600/72 Heading H4P An arrangement initiates call charging in a telegraphic system, on receipt of any character of international code No. 2, after initial connection and receipt of a pulse of predetermined duration except a specified one, e.g. "carriage return", which character designates a non- chargeable communication. Signals of larger duration than code No. 2 also block the charging circuitry. Line signal detectors (TL1 or TL2) may be responsive to either + Ve or - Ve excursions of the line respectively, hence are connected to different inputs E2, E3 of a discriminator DT. When a positive signal appears at input E1 due to closure of a contact (p, not shown), indicating that a call is about to proceed, transistor TE1 blocks, hence inverter IV1 provides a 1 output which has no effect on the apparatus. When the line becomes - Ve, with a TL1 detector, +Ve is applied to E2 and transistor T2 blocks giving 0 inputs to gates 0,3 which provide 1 outputs. A similar effect is achieved when line becomes + Ve with a TL2 detector. Gate CM1 opens giving 0 to M1 and through inverter CM2 a 1 to M2. Clock M1, M2 is started and applies 100 c.p.s. to counter C1. Gate 0 also gives a 1 output opening gates FS, RZ2 giving 0 outputs which unlock counting elements C1, C2 which give pulses at 10m./sec. intervals. At a count of 13, gate 13 opens and supplies 0 to E.C. of flip-flop 1, 2 which reverses. The line becomes + Ve between counts 15 and 17 hence transistor TE2 reverses to 1 output and gate 3#0. Gate 0 is blocked by flip-flop 1, 2, hence CM1 remains open. At the beginning of count 18, gate 18 opens closing CM1, stopping the clock and an input to FS sets it to 1 which locks elements C1 through inverter RZ1. Gate 4 is opened which unblocks D1 supplying +Ve to output S1 confirming the 150m./sec. pulse. The count on 18 remains until receipt of an answer back signal from a called subscriber. Operations for line pulses less than 130m. /sec. and greater than 170m./sec. are described On receipt of first character "carriage return" the clock is restarted and counter steps to 31, the resulting operations causing a + Ve polarity at S2 indicating non-charging. When the apparatus receives a character other than "carriage return" a +Ve output is given at S3, thus charging commences.
