Title: Code generating keyboards
Inventor: PETERS JOHN WILLIAM
IPC: H04L13/16
Filed: 1965-06-18
Abstract: 1,060,878. Selective printing. CREED & CO. Ltd. June 18, 1965, No. 25871/65. Heading B6F. [Also in Division H4] A keyboard transmitter in which depression of a key provides a parallel signal which passes via a store to a distributer comprises means for automatically holding down a second key if that key is depressed when the store is full. In the embodiment described an actuated key enables an encoder which produces a 5-bit signal. This is gated to a first store whose output is gated to a second store which feeds the distributer. An arrangement of gates, toggles, and delays controls the gates and the resetting of the stores. This arrangement is fed by the Stop bit of the transmitted signal and by a signal from a circuit which checks the parallel signal from the encoder. If a second key is pressed when the first store is full, and if the encoder check is correct, the arrangement operates an electromagnet which holds down the second key until the first store is read out, the second key's 5-bit signal then passing from the encoder to the first store and the electromagnet being de-energized to release the key.

[Also in Division F2] The shaft 2 of an hydraulically operated reversible winch drum 31 is movable from a position in which the drum is braked to one in which the drum is unbraked, by an hydraulic piston-and-cylinder device which is actuated in the same direction in response to pressurized fluid driving the drum motor in either direction. The drum shaft 2 is eccentrically mounted in lever arms 3, an extension 7 of one of which is rotatably acted upon by the hydraulic device against the resistance of a spring return arrangement 13, 14, 15. The hydraulic device comprises a cylinder 20 housing a lower piston 22 and an upper piston 21 spring biased apart, a ram 19 on the piston 21 extending from the cylinder to receive a push-rod 12 engageable with the extension 7. A port 26 in the cylinder wall at the lower end thereof and a port 27 between the two pistons, are coupled to the two hydraulic lines controlling the winch motor and pressure is supplied to one port or the other depending on the direction of rotation of the drum, whereupon either the two pistons are biased apart and the rod 12 moves the arm 3 to release the drum brake, or the piston 22 is raised to compress the spring 24 and move the piston to move the arm 3. A port 49 is provided at the top of the cylinder wall to facilitate a double action of the device, but is normally connected to exhaust. The hydraulic circuit includes a manual valve to selectively couple two winch drums in parallel, and a counterbalance valve between the motor supply and return lines. Each winch brake comprises a pair of brake drums on the winch drum and engageable with brake shoes secured to the winch mounting structure.

A piston packing for hydraulic or pneumatic cylinders is of frusto-conical shape and formed with grooves 2 around its periphery, the webs 4 between the grooves being provided with recesses 5 connecting the grooves. In operation, the different supporting force exerted by the groove edges during the pressure and release strokes rotates the packing so as to reduce the wear of the packing caused by, for example, the compensating aperture disposed in the wall of an hydraulic brake master cylinder. The grooves may be inclined as shown, the lowest point in each groove being in the centre of the groove; if desired, the grooves may be asymmetrical so that the lowest point is spaced from the centre of the groove. In Figs. 4, 5 and 6 (not shown), the grooves are parallel with the packing axis and have an asymmetrical shape.

[Class 4] The orientable front wheel of a tricycle undercarriage has its directional movement automatically locked as soon as part of the weight of the aircraft transmitted by the wheel to the ground becomes less than a predetermined value. Wheel fork 1 has at the top a notch to be engaged by spring- operated locking-bolt 6 held inoperative, as shown, by a cable 9 passing over pulleys on arms 11, 15 connected between the relatively movable parts of the shock-absorber and being attached at its other end to a point (not shown) on a suspended part of the aircraft ; as the wheelload is diminished, the arms 11, 15 are straightened out and the cable is slackened to allow engagement of the bolt 6 with the notch. Turning of the wheel about its steering pivot is obtained by a cable 19, with a spring-tension device at each end and carried on a drum 18 mounted on the fork ; either end of the cable is pulled by one of the hydraulic pistons shown to give a small turn to the drum, the action being repeated by the pilot as required.

Abstract: 231,397. Vondra, K. Nov. 3, 1924. Key actions. - The key-levers are coupled together in combinations of two, in such a way that the selection of a character, on either a type-wheel or type lever, necessitates the depression of two keys. As shown in Fig. 2, the type-levers 5 and key-levers 10 are pivoted on a shaft 4, and the free end 3 of each type-lever forms a pivot for the mid-point of a cross-beam 2, which is provided at each end with an upright 6 disposed beneath a key-lever. The beams 2 are of different lengths and span two or more key-levers, as shown diagrammatically in Fig. 1, each key-lever co-operating with several beams. Depression of any one key 1 merely produces the idle rocking of the beams that have their upright ends disposed beneath it. The pivoted beams 2 may be replaced by slidable rods 15, Fig. 5, which are guided in brackets 14 at the ends of the type-levers and are merely moved to the right or left when one of their associated keys 1 is depressed, but depress the end of the type-lever when both keys are depressed. In a modification, Fig. 8, the key-levers 1 are arranged in intermeshing groups, the key-levers constituting a group being connected by a bridge-piece 7, each group being controlled by a key. The key-levers 1 adjacent to any typelever 5 belong to two different groups, and engage the ends of slidable pellets 15<1> arranged transversely in the type-lever when the keys of their respective group are actuated. The slidable pellets may be replaced by swinging pendants having bevelled shoulders to engage the keylevers. When only one key-lever adjacent to a pendant is depressed, the pendant swings idly about its axis at the end of the type-lever.
