Title: Improvements in keyboard transmitters for telegraph systems or the like
Inventor: TERLECKI RENAT
IPC: H04L13/16
Filed: 1962-09-11
Abstract: 1,011,358. Typewriters &c. BRITISH TELECOMMUNICATIONS RESEARCH Ltd. Dec. 11, 1963 [Sept. 11, 1962], No. 34667/62. Heading B6F. [Also in Division H4] The keyboard of a telegraph transmitter is detachable from the main frame and can be replaced by a keyboard of different character layout. In addition, a cross-connecting unit, which produces a coded, output corresponding to depression of a key, can be replaced by another unit to provide a different corresponding coded output. The keyboard unit 1 is clipped to the frame by springs 3, but the space bar is not detachable. Depression of a key rocks an associated bar 7 about pivot 8 whereby lever 41 moves clockwise about pivot 40; lever 41 is common to all the bars 7 and moves pawl 42 upwards to disengage latch 36 from arm 34. Armature 27 and lever 30 now move anticlockwise, moving bar 32 to the right so that bar 7 is locked by bar 33. Movement of armature 27 operates a switch which starts a distributer. At the end of the distributer cycle the electromagnet is energized and latch 36 re-engages arm 35. Each bar 7 operates a corresponding switch which feeds a diode cross-connecting unit. This generates a code signal corresponding to the key depressed. If a key is pressed for a time longer than a transmitted character the character is not repeated since, on energization of the magnet at the end of the distributer cycle, the bar 32 is latched by 36. Depression of a key for too short a time has no adverse effect since the corresponding bar 7 is locked by bar 33 during the distributer cycle. Depression of more than one key at a time is prevented by a ballbearing and wedge arrangement 12, 13.

Title: Improvements in or relating to throttle valves for high-pressure steam accumulator fireless locomotives
IPC: B61C1/04
Filed: 1946-11-22
Abstract: 637,797. Valves. RUTHS INTERNATIONAL ACCUMULATORS, Ltd. (Wiener Lokomotivfabrik Akt.-Ges.). Nov. 22, 1946, No. 34727. [Class 135] In a combined piston and lift throttle valve for a fireless steam locomotive having highpressure accumulators, the steam from the accurnulators is throttled to its working pressure before delivery to the locomotive cylinders, and the valve is provided with one or more guide surfaces to reduce the resistance to steam flow when the valve is fully open. As shown, a casing 1, having an inlet E and an outlet A, houses a main stop valve 18 and a throttlevalve 4. The valve 4 is secured to an element 5 having a guide surface s, and is integral with a hollow piston throttling element e slidable in a ported liner 2. The valve 4 coacts with a seat b on the liner and has a port h controlled by an auxiliary valve g on the spindle 6 of the valve 4. The spindle 6 is guided in end bushes 7, is operable by a lever 11, and carries a stop 12 for engagement in a slot y in the element 5 of the valve 4. Clockwise movement of the lever 11 results in opening of the auxiliary valve g to pressure balance the valve 4 and hence permit easy opening of the latter. When the valve 4 is fully open, the resistance to the flow of steam therethrough is reduced to a minimum by the guide surface 8 and the surface r of the valve 4. When the valve is closed, since the piston-rings 14 are not absolutely steam-tight, the upper side of the valve 4 will be subjected to outlet pressure and its lower side to inlet pressure, and the pressure difference will hold the valves 4, g on their seats. In a modified construction, the leaky piston is disposed at the end of the valve 4 remote from the inlet, and is made solid except for ports therethrough controlled by the auxiliary valve g and acts as a balancing piston, whilst the lift element also constitutes the throttling element. In another form, the piston is arranged on the inlet side of the lift element to throttle the valve inlet, and inlet pressure leaking behind the piston between its rings and the liner when the valve is closed is released by the auxiliary valve to pressure balance the valve and assist its opening.

Title: Improvements in or relating to disc brakes
IPC: F16D55/00
Filed: 1964-08-26
Abstract: 1,028,649. Disc brakes. H. TEVES, E. A. TEVES, and M. TAUSEND, [trading as ALFRED TEVES MASCHINEN-UND ARMATUBENFABRIK KOMM. GES.]. Aug. 26, 1964 [Sept. 4, 1963], No. 34928/64. Heading F2E. In a spot-type disc brake an actuating lever 8 is adapted to be turned to engage a thrust member 9 by way of an helically rising slideway 17 formed on the shaft 14 of the actuating lever 8 and a slideway 18 on the thrust member 9 to move the latter axially in the brake casing 3 against a screwed connection 10, 11 to actuate a brake pad 36 against a rotating disc 1 and, by reaction, apply another brake pad 7 against the other surface of the brake disc. An automatic adjusting mechanism is provided to adjust for wear of the friction pads and consists of a ratchet-wheel 26 rotatable with the shaft 14 and a spring member 30 engages at one end with the inner screwed connection 11 and at the outer end engages the teeth of the ratchet wheel 26 so that when the ratchet wheel is rotated the spring member 30 runs up the inclined backs of the ratchet teeth and if the wear of the friction pads is sufficient, the spring member 30 jumps over the top of the teeth 28 into the next tooth space to take out the wear. The thrust member is non-positively connected with the screwthreaded member 11 through a friction bush 21. In operation, to apply the brake the operating lever 8 is pivoted so that the surfaces 17, 18 run up on one another and the thrust member 9 moves towards the screw-threaded connection 10, 11. Since the thrust member 9 is guided in splining 22 of the brake casing 3 it cannot rotate but just moves axially. Under a braking pressure the screw-threaded connection 10, 11 is self-locking and since the screw 23 prevents the outer screw-threaded element 10 from rotating the screw-threaded connection 10, 11 moves axially through the carrier 35 of the brake friction pad 36 in the direction of the brake disc 1. The collar 15 of the operating lever shaft 14 is pressed against the screw-threaded cover 13 and acts via the brake casing to move the brake friction pad 7 to the right and against the disc 1.

Abstract: 487,940. Cathode-ray tubes. LINDEMANN, F. A. Dec. 28, 1936, No. 35466. [Class 39 (i)] For generating an image signal in a television transmitter a photo-electric mosaic is formed on a plate 2 of low conductivity such as soda glass ; a grid 4 is placed on the side of the plate remote from the mosaic and the plate is scanned through the grid by a beam from a gun 5. The potential image of the mosaic formed on the back of the plate controls the flow of electrons from the beam to the grid, those electrons not passing to the grid being taken up by the plate to assist in its return to datum potential. A transparent anode 1 collects the photo-electrons emitted from the mosaic. If a separate photo-electric cathode is used to form an electron image for transfer to the plate, the latter need not be a mosaic but a plate of low conductivity. The transverse conductivity of the plate will be less than that through the plate ; the latter may be increased by inclusion of particles as described in Specification 482,959. The grid may be replaced by a collecting ring. The charge image may be produced by secondary emission, a mosaic being then dispensed with. Additional mosaic elements may be deposited on the side of the sheet 2 remote from the anode 1 ; these additional elements may be coated to produce secondary emission.
