Title: Improvements relating to token instruments for the control of railway traffic
IPC: B61L23/24
Filed: 1929-07-26
Abstract: 337,353. Roberts, W. S., Burton, J. H., and Railway Signal Co., Ltd. July 26, 1929. Staff, tablet, and ticket systems.-The staff opening 1 of a token instrument is normally obstructed by a bolt 3 the movement of which for permissive working is controlled by a polarized electric lock 8 operated from the other station by a control mechanism. The bolt 3 is controlled by a locking lever 4 which is attached to the rotor 7 of the lock 8. An inward movement of a spring- pressed rod 13 by pressure on a knob so connects the energizing coil of lock 8 with line that the direction of the current is such as to release the lever 4 which enables the bolt 3 to be withdrawn. To prevent more than one staff being withdrawn a peg 11 secures the locking disc 9 on the inward movement of the bar 13. As shown in Fig. 5 the control mechanism comprises a rotatable spindle 19 which is adapted to be released from its normally locked position by the energization of an electromagnet 26. Rotation of the spindle breaks a contact 63 in the circuit of the lock mechanism 8, and also releases by means of a bar 35 a second spindle 40 which is adapted to 'be rotated by a. spindle 41 through reduction gearing 42. Spindle 41 is normally locked by a disc 44 which engages by means of projections 45 a forked member 46 mounted upon the rotor of a polarized electric lock mechanism 47 described in Specification 337,045. If current flowing in one direction is supplied to the lock mechanism 47 the spindle 41 can be rotated through a quarter of a revolution in the clockwise direction and when current of the reverse direction is supplied it can be rotated in an anticlockwise direction. The direction of the current is controlled by a commutator 60 secured to the spindle 40. The circuit of the lock mechanism 47 includes a commutator 50 which when rocked by means of a tapping key completes the circuit for the mechanism 47 and the sending circuit of the instrument. For permissive working the operator at one end of the block section A first transmits alternating current to the magnet 26 at B thereby releasing the spindle 19 and then transmits direct current to the mechanism 47 which permits a rotation of the spindle 41. This is registered by an indicator connected to the spindle 40. The operator at B then transmits direct current which allows the operator at A to bring a staff to the head of his instrument whence it can be removed finally by the operation of the sliding bolt. The usual locking mechanism for controlling the insertion of staffs may be modified by adapting the rocking lever upon which the polarized lock mechanism is mounted to be raised by a tapper key. The rotation of the locking discs is then effected by an external knob on the disc spindle and a spring catch retains a. staff in position during such rotation. In a further modification the lock mechanism is fixed and its rotary element is provided with a forked member adapted to co-operate with a locking disc and is controlled by a tapper key.

Title: Sealing structure
IPC: F16J15/32
Filed: 1960-07-01
Abstract: 901,328. Stuffing-box Substitutes; piston packing. LOCKHEED AIRCRAFT CORPORATION. July 1, 1960 [July 1, 1959], No. 23058/60. Classes 122 (1) and 122 (5). A sealing structure between stationary or relatively-movable members 12, 13, Fig. 1, comprises a metal ring 18 having a rigid body-portion 22 and inner and outer annular legs integral with and diverging from the body, and a loading ring 21 forcibly engaging the ring 18 midway along the length of the inner and outer legs to produce leg flexing action and sealing engagement. The member 12 is shown as a shaft rotatable or longitudinally movable in a gland body 13 and the ring 18 is of X cross-section and housed in an annular chamber 11 in the body. The ring 18 is preferably made of stainless steel, with or without a wear-resistant coating, and is of such size as to fit easily over the shaft 12. Loading rings 20, 21 are disposed on opposite sides of the ring 18 so that, upon screwing up of a nut 14, the rings 20, 21 move towards each other and force the associated legs into engagement with the shaft 12 and body 13. Instead of using the nut 14, the loading rings may be forced together by a clamp, and in another form these rings may be formed integrally with the nut 14 or body 13. In the modification shown in Fig. 5, the sealing-ring 34 is V-shaped and its legs are urged by the loading ring into engagement with the shaft and body. In another arrangement, the outer legs do not engage the body, sealing then being effected between the legs and loading rings and between the inner legs and the shaft. The ends of the legs may be flat, pointed, chiselled or rounded and the loading rings may be of circular cross-section with smooth or serrated surfaces. If desired, sealing may be effected by a number of the abovedescribed structures each housed in a separate chamber, and in another arrangement the structure is described as fitted on a piston.

Title: Data-processing systems
IPC: G06F9/48
Filed: 1971-04-19
Abstract: 1334122 Testing programs SIEMENS AG 19 April 1971 [6 March 1970] 23119/71 Heading G4A In order to prevent a newly entered program from interfering with established programs in a data processor the execution of the new program is monitored, at least during its first run, by a tracing program, the instructions of which check the instructions in the new program, the tracing program having a higher priority than the new program, the arrangement being that the priority of the tracing program is temporarily reduced below that of the new program each time the next instruction to be executed in the new program has been checked so that the checked instruction is executed during a priority interrupt of the tracing program, and increased above that of the new program each time a previously checked instruction of the new program has been executed. The effect is that each instruction of the new program is checked prior to its execution, e.g. to ascertain whether it requires storage allotted to an established program &c., and yet the new program is executed without having its priority altered so as to simulate an unmonitored run. The tracing program is run and an instruction in the new program specified by an address held in an auxiliary store is checked. The instruction following the last checking instruction in the tracing program causes a special instruction to be substituted for the succeeding instruction in the new program. The final instruction in the tracing program causes the priority of the tracing program to be lowered and the tracing program is interrupted by the new program which commences with the instruction specified by the auxiliary store, i.e. the checked instruction. This instruction is executed and an instruction counter is incremented to access the next instruction, which is the substituted instruction referred to above, in the usual way. This instruction raises the priority of the tracing program which thus interrupts the new program. The first few instructions of the tracing program, the first of which is specified by a register the contents of which are fixed, cause the previously substituted instruction in the new program to be replaced and the address held in the auxiliary store to be modified so as to relate to the instruction in the new program which follows the previously checked and executed instruction. The process then continues.

Abstract: 914,663. Dropping from aircraft. EASTERN ROTORCRAFT CORPORATION. June 27, 1961 [June 30, 1960], No. 23179/61. Addition to 839,629. Class 9 (2). [Also in Group XXV] In a cargo release hook, similar to that described in the parent Specification, particularly to the modification therein with a pivoted link 83 at the end of the latch, the control lever 24 for locking and releasing the latch 20 of the hook 12 is moved by toggle-links 32, 33; the link 33 which is pivoted at both ends moving away from a stop pin 36 on the lever 24 when the links are moved from the latch-locked position shown, through a dead-centre position, to the released position of the latch and hook, Fig. 3 (not shown). For release, raising of the lever 24 about its pivot 27, whether by a cable 38, by hand lever 48 or by rotary electromagnet 44, is performed by rotation of a shaft 28 with which the link 32 and a lever 31 engaged by the cable 38 are integral. The hand lever 48 is keyed on the shaft while the spindle of the magnet 44 fits concentrically in the hollow interior of the shaft, Fig. 4 (not shown), and has a notched end engaging a transverse pin in the interior. The spindle notch may provide lost motion so that the spindle is not moved by actuation of the cable lever 31. The togglelink 33 is biased towards the stop pin 36 by a spring 42. When the lever 24 has been raised for the open position of the mechanism, its end operates a switch 50 to break the magnet circuit and lights an indicator.

Title: Improvements in or relating to fluid-pressure servomotors
IPC: F15B9/10
Filed: 1944-11-22
Abstract: 587,427. Fluid-pressure servomotorcontrol systems. STAUDE, E. G., and STAUDE, O. B. Nov. 22, 1944, No. 23230. Convention date, Dec. 8, 1943. [Class 135] A fluid-pressure servomotor comprises a pump 98, Fig. 3, normally circulating pressure liquid continuously through apertures in vanes 66, 67, which apertures can be closed by valves 74, 77 operable selectively to cause the pressure to build up behind a vane to move the latter. As applied to the actuation of an aircraft control surface, cables 1,2, Fig. 1, are connected to the pilot's control, and when moved to the left, for example, cause a lever 7 to swing anti-clockwise about its pivot 8 on a lever 10, the latter being connected through cables 14, 15 to the control surface. Besides swinging lever 7, the pull on cable 1 will also be transmitted directly throughpivot 8 to cable 14 and will cause the latter to start moving to the left. The lower end of lever 7 carries a tooth 31 engaging in a recess in a lever 33 keyed to a shaft 34 rotating in a sleeve 39 on which the lever 10 is keyed, and the anticlockwise movement of lever 7 will rotate lever 33 in a clockwise direction. The latter lever carries a see-saw lever 50 which will depress ball valve 77 to close the aperture in vane 67, and the pressure liquid from pump outlet passage 107 will build up behind the vane and move it in a clockwise direction. As the vanes are carried by sleeve 39, lever 10 will be rotated and will move cable 14 to the left. Movable vanes 66, 67 co-operate with fixed vanes 80, 81, and the liquid on the upper side of vane 67 will be forced through port 117, pipe 118, and port 119, through the aperture in vane 66 and out through port 87 and pipe 88 to the inlet passage 90 of the pump. The valves are re-centred by a spring-pressed lever 25 pivoted on lever 10 and engaging in a recess 28 in lever 7. The fluid pressure acting on the ball valves when the latter are closed will be transmitted to the pilot to give " feel." A relief valve 113 between the inlet and outlet passages of the pump permits the liquid to circulate freely when the lower supply fails and direct manual actuation of the control surface through lever 7 is required.
