Title: Improvements in or relating to control means for electropneumatic compressed air brakes
IPC: B60T13/68
Filed: 1962-01-11
Abstract: 955,575. Compressed air brakes. KNORR-BREMSE G.m.b.H. Jan. 11, 1962 [Jan. 12, 1961], No. 1121/62. Heading F2F. Control means for electropneumatic compressed air brakes for railway vehicles comprises an electromagnetic valve 23 which, during braking operations, shuts off a control line from a manually actuated driver's valve 13 to a relay valve 5 supervising the pressure in the main air pipe 55 only when the electric brake control system 87, 89 is ready for operation. The valve 23 is in the form of a change-over valve which, when in the position for shutting off the valve 5 from the driver's valve 13, connects the control pipe branch leading to the valve 5 with a pressure regulator 9 which is connected to a compressed air source 1 and pressurizes the valve 5. To cause braking the driver's valve 13 is moved to a braking position whereby the switch 17 is closed so that the valve 23 changes over due to the electromagnet 33 being energized to connect the chambers 31, 29. Regulation pressure is maintained by regulator 9 in pipe line 37 and the reduction in pressure in pipe line 19 produced by the drivers valve causes piston 39 to lift so as to firstly close switch 75 and then switch 77. Brake control valves (not shown) admit compressed air to the brake cylinders and through pipe line 71 to space 67. The pressure loading the piston 69 lowers the piston system 39, 69 until rocking member 73 bears on abutment 81. Switch 77 is thereby opened and a neutral position of the brake is obtained. If an electrical fault occurs the valve 23 changes back to connect chambers 21, 31 so that the driver's valve also lowers the pressure in the cylinder spaces 41, 45. The switch 27 is returned to the release position and the valve 5, by opening valve 57, 61, introduces a fall in pressure corresponding to the braking stage at the time in the main air pipe 55 which by way of the brake control valves pressurises the brake cylinders.

Title: Synchronous electric distant control apparatus
IPC: G08C19/38
Filed: 1922-01-13
Abstract: 174,082. Granat, E. Jan. 14, 1921, [Convention date]. Selective distant control systems. - Relates to electrical apparatus for transmitting rotary movements to a distance,applicable to order telegraphs, and to the control of artillery aiming-marks, gun-sights, guns, gun-turrets, torpedo-tubes, searchlights, rudders, telemeter and altimeter apparatus, etc.; and consists in the combination of a transmitter of the type in which the commutator of a motor running light is employed as a potential divider, with a receiver of the type having polyphase stator windings and a rotor polarized by direct current or vice versa. The receiver may operate directly on the object to be controlled, or may function as a servo-motor. The transmitter A comprises a potential divider consisting of a motor driven by direct current which is supplied to the commutator 6 through brushes 16, 17, the motor being allowed to run light during use. A set of three equidistant brushes 18, 19, 20 is rotated in accordance with the movement to be transmitted, a polyphase current whose frequency depends on the speed of rotation of the brushes being thus communicated over the line-wires 21, 22, 23, to the receiving-apparatus B, with or without the interposition of transformers. The receiving-apparatus B comprises a closed stator winding, to three equidistant points 28, 29, 30, of which the line-wires are connected; and a closed rotor winding 31 to which direct current is supplied throught slip-rings at 32, 33. The rotor, being magnetized by the direct current, will follow the rotating field of the stator. The Specification gives an analysis of the conditions under which the receiving and transmitting apparatus would get out of step, and shows that by inserting inductances 24, 25, 26 in the line-wires it is possible to increase the maximum speed at which the apparatus will give accurate performance. The inductances 24, 25, 26 may also be used as blow-out coils to prevent sparking at the brushes. The transmitter A may be converted for use as a receiver by disconnecting the brushes 16, 17, and locking the brushes 18, 19, 20 to the armature-shaft. A plurality of transmitters working to corresponding receivers may be operated by a single handle at the transmitting station, each transmitter being given an individual phase-adjustment or correction.

Title: Improvements relating to electric motor control systems
Inventor: DOLAN HARRY
IPC: B66B1/30
Filed: 1954-01-15
Abstract: 765,875. Automatic speed control systems. ENGLISH ELECTRIC CO., Ltd. Jan. 14, 1955 [Jan. 15, 1954], No. 1245/54. Addition to 715,583. Class 38 (4). [Also in Group XXXVII] The speed control system for a hoist as described in the parent Specification is modified in that (1) the motor is connected for dynamic braking if the speed exceeds the decreasing reference value during deceleration by more than a certain amount; (2) the motor is reconnected to the power supply if the speed falls more than a certain amount below the reference value during braking. During the deceleration period of the winding programme, the reference voltage applied to magnetic amplifier control winding 18b, Fig. 1, from the hoist-position-operated potentiometer 19 may fall below the opposing voltage in winding 18a representing the speed of the induction winding motor 10. The resulting negative overspeed signal decreases the torque applied to the motor 21, so that hydraulic actuator 25 is displaced to increase the rotor resistance 14. An overspeed signal persisting with maximum rotor resistance causes a further reduction in the torque of motor 21 and a consequent movement of linkage 23 to move contacts EB1-EB4 from their shown positions. An overspeed signal of sufficient amplitude energizes a relay T over a rectifier 38, so that its contact T1, Fig. 2, is opened to de-energize a relay K, whereby the relevant motoring contactor F or R is de-energized to disconnect power from the stator. A braking contactor B is then energized over now-closed contacts EB4, K4 to connect D.C. braking sources 12, 13 to the stator. A relay G is also energized by closure of contactor B to reverse the inputs to windings 18a, 18b, whereby the rotor resistance 14 is reduced to increase the dynamic braking torque, contacts EB1-EB4 return to their shown positions, relay T is de-energized, and a relay Y is energized over now-closed contact G5. If the speed error should become positive during braking, contacts EB1-EB4 move again from their shown positions and relay T is re-energized by an apparent negative error signal of sufficient amplitude, the inputs to windings 18a, 18b being still reversed. Relay K is then reenergized over now-closed contacts T2, EB3, Y1 to reconnect power to the stator, and contactor B is de-energized to disconnect braking sources 12, 13. Finally, relay G is de-energized to reverse the winding inputs, whereby relays T and Y are de-energized. Resistor RY and condenser CY delay the de-energization of relay Y until contacts T, or EB1 have reclosed. If manual control is desired, the slider of potentiometer 19 is coupled to the driver's lever, though the reference voltage is still automatically controlled during deceleration. The limiting and safety circuits are as described in the parent Specification.

Patent GB-816523-A (GB)
Title: Broaching machine
IPC: B23D37/04
Filed: 1957-01-14
Abstract: 816,523. Broaching. DETROIT BROACH & MACHINE CO. Jan. 14, 1957 [Jan. 16, 1956], No. 1319/57. Class 83 (3). A pull-boraching machine comprises safety means to render the machine inoperative when a handling slide 72 attempts to push the broach B through the work. Tool-holders; tools.-When the broach-carrying slide 21 is moved downwardly by hydraulic means 64, 66, a spring 44, Fig. 6, moves a sleeve 38 upwardly to cam four pins 60 into engagement with a groove 61 on the borach. The pins are released on a return-stroke when a collar 36 is arrested by the bottom of the work-table 12. The upper end of the broach is gripped frictionally by a spring-pressed bevelled plunger engaging a bevelled groove in the broach. The plunger is housed in a block 82 on the handling- slide 72, which is secured to hydraulicallyoperated rods 108 by a pair of pins adapted to shear at a given load. When the broach is in its correct upper position it engages a rod 126 depending from a fixed-bracket of the machine and actuates a switch LS7 to enable a cycle of operations to be initiated. At the beginning of an operation, a switch LS5 is also closed by the slide 21 in its upper position. When a startbutton is pressed, a solenoid-valve is actuated to cause the handling-slide 72 to move the bottom of the broach down through the work W. Actuation of a switch by a cam on the handling- slide causes a solenoid-valve to be operated to move the slide 21 downwardly. The handling- slide continues to move down by a small amount, and a switch is actuated by the pressure build-up when the slide reaches its lower limit of movement. When a cam 181 on the slide 21 actuates a switch LS2, the handling-slide is moved to its upper position. Speed-controlling.-Before the broach starts to cut, a check-valve prevents too-rapid movement of the slide 21, but when pressure rises, as the broach engages the work, a pressure-operated solenoid-valve by-passes the check valve. Movement of the slide 21 ceases when a further cam on the slide operates a switch LS3. The broach is then clear of the work, which may be removed. When a start-button is again pressed, the handling-slide moves down, the main slide moves up, and a cam thereon operates a switch LS4 to cause the handling-slide to move up again. The slides then continue to their upper positions. If the slide 21 slips down, the switch LS5 is released and causes it to be raised again. Stop-motions.-If the slide 21 moves down without gripping the broach, the handling-slide will first rise to its upper position and then, as it continues to move down with the slide 21, will attempt to push the broach through the work. The shear-pins then break and the handling- slide is pushed upwardly on the slide 21 so that a cam on the slide 72 closes a switch LS6 (not shown), which stops the machine and illuminates a warning-light. A manual switch must then be operated before the machine can be restarted. A manually-operated lever 230 serves to stop the machine at any time.

Title: Improvements relating to feed mechanism for recording paper strips
IPC: G01D15/24
Filed: 1945-01-16
Abstract: 589,829. Recording-apparatus. LANDIS & GYR SOC. ANON. Jan. 16, 1945, No. 1333. Convention date, Dec. 4, 1943. [Classes 106 (i) and 106 (iv)] A paper-feed mechanism for apparatus, which records any magnitude, depending on time, on paper previously printed with time marks, comprises a pick-up device whereby, upon the recurrence of the mains potential after an interruption, the paper is advanced and the source of energy for driving the pick-up device is replenished according to the amounts delayed during the interruption. A mains-driven motor 1 drives a shaft II intermittently as a cam 25 is freed from a locking lever 24 controlled by a clockwork escapement (not shown) and each periodic revolution of the shaft II advances a paper strip 39, winds a spring barrel 7 and rotates a sun-wheel 41. Each half revolution of a shaft IX, as determined by the clockwork escapement, frees a shaft VIII to make half a revolution under the power of the spring barrel 7 and through a sun-wheel 16 causes a planetwheel 17, fixed on a shaft X, to revolve and so allow a lever 18 to free locking levers 20, 23 and the pawl 24, the consequent action of the shaft II and sun-wheel 41 reversing the rotation of the shaft X and relocking the system. However, upon an interruption in the mains potential, the drive to the shaft II fails and the system remains unlocked. The spring barrel 7 continues its intermittent drive to the shaft X and the lever 20 moves out of range of the lever 18 as a pinion 27 drives a travelling nut 28 along a shaft XII. When the current is resumed, the shaft II, being free to rotate, advances the paper strip, winds the spring barrel and, through the sun-wheel 41, reverses the movement of the nut 28 and lever 20 until the latter finally engages the lever 18 and locks the shaft II, by which time due compensation has been. made in the paper-feeding and rewinding processes.

Address modification is effected using a number generated during a computation. In a stored programme digital computer an instruction, including an operand address, is taken from a store and, if it has a control bit signifying indexed addressing, the sign of the number in the accumulator (Fig. 1, not shown) is examined and, if the sign is positive, the operand address is unchanged whereas, if the sign is negative, the operand address has a 1 or 2 added thereto by logic means. This is stated to replace separate index registers and is for use for various iterative routines. For example, for an iterative routine for plotting a line having X and Y components (where X/Y=A/B) for C increments the routine on Fig. 3 is followed where A and B occupy two successive address locations. In another embodiment (Fig. 4, not shown) multiplication is effected where the sign determines whether or not the multiplicand is to be added. In another embodiment the accumulator sign causes choice of a conditional jump. The sign of the accumulator and the odd/even nature of one bit can be combined to give a choice of 4 addresses.  Other features.-The computer memory may be a magnetic core, thin film, MOS, drum, disc or delay line, the output may be a magnetic tape, a typewriter, or an electronic plotter and the arithmetic unit may use fixed or variable word length.
