Title: Improvements in and relating to couplings, holding devices and the like
IPC: B21D39/04
Filed: 1921-07-23
Abstract: 192,101. Brown, R. S. July 23, 1921. Rod couplings; couplings, disconnectible; overlap joints with packing at base or mouth of socket.-In connecting rods, bars, pipes, or stems by insertion of the end of one into a socket on, or similarly connected to the other, the engaging parts are formed with shoulders or ledges which can be engaged when the socket member is deformed by pressure applied at one or more points. Figs. 1, 2, and 3 show a rod a having shoulders b<1>, b<2> which can enter the socket c when deformed and engage in the groove A when the socket resumes its normal shape by elasticity. Clearances e are cut on the member a to permit deformation of the socket for release. The members a and c may be rods or pipes. Figs. 4, 5 and 6 show the invention applied to bars. The inserted member may be laminated as in Fig. 4, or formed from a pair of bars pressed apart within the limits of the stud D by a spring A as shown in Fig. 5. The socket B, Fig. 6, must be deformed for engagement with, and disengagement from, the member shown in Fig. 4, the projection d(<1>)(<2>) of the socket co-operating with the grooves b<1>, b<2> in the bars. The member shown in Fig. 5 may be automatically engaged with the socket C, Fig. 6, by the spring A allowing the recesses b<3>, b<4> to snap into register with the annular projection d(<3>)(<4>). Deformation of the socket is necessary for release. In the form of socket shown in Figs. 13 and 14, which may form a junction box, bars, pipes or rods are inserted from both ends, the bevelled faces G of the shoulders d enabling the pipe or rod members to be inserted by forcing them in. The socket is deformed for release by leverage of the rod A in the bracket B. The shape of the socket facilitates deformation to allow entry of the bars, rods or pipes. Fig. 19 shows a form of inserted rod member for engaging a circular socket with a continuous annular shoulder within its bore, the shoulder engaging the pair of grooves b', b<2>. The objects of the flats e, e<1> is to provide clearance to allow deformation of the socket for release, and the ribs h prevent the socket from being deformed to a sufficient extent to cause the shoulder to foul the corners or ends of the recesses b<1>, b<2>. Two similar rods or tubes a', a<2>, Fig. 33, may be joined by being inserted into opposite ends of a socket c and a packing-ring j placed between them. They are released by deforming the socket, when the shoulders d<1>, d<2>, are disengaged from the recessed b<1>, b<2>. Figs. 24, 28, 29 and 31 show diagramatically, partial sections through various forms of sockets and correspondingly shouldered inserted members, with packing means i provided. The dotted lines show only the shape of the socket at the parts to be pressed for deformation, and the full lines show the engaging parts. In Fig. 31, the socket has to be deformed to release the shoulders b, d, before the parts can be unscrewed.

IPC: B63H21/22
Filed: 1959-06-11
Abstract: 936,608. Reverse-gear control. BLOCTUBE CONTROLS Ltd. June 3, 1960 [June 11, 1959], No. 20030/59. Class 80 (2). In a marine remote control apparatus wherein oppositely arranged separate levers 2 (not shown), 1, fast on coaxial shafts 4, 3 journalled in a casing 5 of a telegraph standard, respectively control engine speed and propeller reversing gear, interlocking means prevents engaging movement of the gear lever 1 unless the speed lever 2 is in or near its zero (idling) position to prevent damage due to attempted reversing gear engagement when, for driving a winch, the engine is running at full or substantial speed. The interlocking means comprises plungers 13, 14 which slide in a web 12, are biased by springs 15 to engage short arcuate slots 7, 10 in plates 6, 9, respectively fast on the shafts 3, 4, and are cammed out of the slots by rounded studs 11, 8 acting on hemispherical plunger enlargements 21. A long arcuate slot 24 in the plate 6 accommodates the plunger 14. One stud 11 is arranged on the plate 9 to effect release of the gear lever 1 when the speed lever 2 is at or near the position of zero engine speed. Three studs 8 are arranged on the plate 6 to effect release of the speed lever 2 when the gear lever 1 at or near the positions of " Neutral," " Ahead " and " Astern." In operation, due to the arcuate nature of the slot 10 a limited speed lever movement simultaneous with that of the gear lever is allowed, for desirable slight acceleration as the gears are engaged. After gear engagement, on further movement of the speed lever the plunger 13 is released; thereafter the gear lever can be moved, if required, to neutral, without reducing engine speed, but since the plunger 13 will then engage the slot 7 the gear lever cannot be returned to the gear engaged position without first bringing the speed lever to or near zero position.

Title: Improvements in and relating to electric pulse generators
IPC: H03K3/55
Filed: 1948-07-28
Abstract: 645,642. Pulse generating circuits. HUGHES & SON, Ltd., H., and WHITFIELD, H. R. July 28, 1948, No. 20182. [Class 40 (vi)] In a pulse generating circuit in which an artificial line is charged through an iron-cored inductor and discharged by means of an electronic switch through a load circuit, the core of the charging inductor saturates during the charging period and the natural period of the series resonant circuit constituted by the line and charging inductor when its core is unsaturated is greater than the required pulse repetition frequency and the time interval between the commencement of charging and saturation of the inductor is less than the pulse repetition period. In this way the voltage across the line at the instant of discharge is independent of the pulse repetition frequency. The Figure shows a pulse generator circuit in which the line 5 is charged from the D.C. supply 1, 2 via the saturable inductor 4 with the gas-filled valve 20 non-conducting. The line is slowly charged until the core of inductor 4 saturates when its effective inductance is greatly reduced and the line charges rapidly to approximately twice the D.C. supply voltage. The charging current thus falls until when the line is charged to its peak voltage, inductor 4 becomes unsaturated and the line commences to discharge slowly until a positive going pulse applied from the generator 21 fires the gas-filled valve 20, whereupon the line discharges almost instantaneously through winding 17 of transformer 16 and an output pulse of substantially square waveform is produced across load 19, Fig. 2 (not shown).
