Filed: 1958-06-13
Abstract: 917,673. Automatic control of aircraft. SPERRY GYROSCOPE CO. L t d. May 29, 1959 [June 13, 1958], No. 19008/58. Class 38 (4). An aircraft is maintained at a desired altitude by an altituderesponsive device automatically controlling the elevators, and, when airspeed falls below a predetermined value, at a desired airspeed by an airspeed-responsive device automatically controlling the engine throttles. As shown, the difference between a signal from an altimeter 4 and a signal representative of a desired altitude controls a servomotor 3 which operates elevators to maintain an aircraft at the desired altitude. An airspeed-responsive differential bellows 15, associated with static and dynamic pressure heads through conduits 16 and 17, adjusts two potentiometers 5 and 6 so that, if airspeed falls below a predetermined value determined by the setting of a spring-loading knob 20, the output voltage of potentiometer 5 is sufficient to energize a self-holding relay 7 and thereby connect potentiometer 6 to a servo system 10 which then adjusts the aircraft engine throttles to maintain airspeed at the predetermined value which may be equal to or above that at which minimum drag occurs. The following modifications are referred to :-(a) Automatic engagement of the automatic elevator control at a predetermined altitude when climbing or descending under manual control. (b) Automatic maintenance at zero of the output of potentiometer 6 when the airspeed control system is disengaged. Specification 626,285 is referred to.

Title: Improvements in or relating to automatic telephone systems
Inventor: BROWELL LESLIE JAMES
IPC: H04Q3/42
Filed: 1962-05-18
Abstract: 971,602. Automatic telephone exchange systems. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. April 8, 1963 [May 18, 1962], No. 19174/62. Heading H4K. In an exchange, particularly one of the so called self-steering kind described in Specification 890,235, the line circuit SLC of each subscriber who is given an incoming call diversion facility is associated at the IDF with an individual relay group SRG which stores the number of the line to which calls are to be diverted. To establish the diversion condition, the subscriber dials from any substation, not necessarily one connected to the same exchange, first a code to obtain access over AP to a dialling-in group DRG and then a secret code to connect to the appropriate relay group SRG. He then dials the number of the diversion line which normally comprises seven digits and is repeated to a store DNS. Relay DS energizes and DRG is released when the caller clears. When an incoming call to the line circuit SLC is marked over MKR, relay TM energizes and a marking over MP controls the connection to SLC which is further extended over a feedbridge TB, the ringing being tripped, to an ex-directory line circuit XSLC. A fresh call is thus originated and is set up under the control of a common sender SDR which receives the digits denoting the diversion line from DNS. Relay TM releases when the call is cleared. To remove the diversion condition the subscriber dials the codes mentioned above to connect to SRG, and a cancel signal is applied to the store DNS, relay DS being released. Specification 890,235 is referred to.

Abstract: 354,933. Control of D.C. motors. IGRANIC ELECTRIC CO., Ltd., 147, Queen Victoria Street, London.-(Cutler- Hammer Manufacturing Co. ; Milwaukee, Wisconsin, U.S.A.) June 26, 1930, No. 19476. [Class 38 (iii).] Safety arrangements ; field and armature control ; non-regenerative braking.-A shunt-wound motor M controlled by a reversible drum controller D is protected from careless manipulation of the controller by a relay 2 in the circuit of the actuating coil of a main switch 1. The relay 2 has two normally opposed windings, one in shunt and one in series with the motor armature. The main switch 1 is closed when the controller is in the " off " position and is maintained closed by auxiliary contacts 1a. If the motor is accelerated or decelerated too quickly or if the controller drum is reversed too quickly, either the series coil 2a or the shunt coil 2b of the relay 2 preponderates and the relay opens, so that the motor is disconnected from its supply by the opening of the main switch 1, and the controller D must be moved to its " off " position to reclose the main switch. When the relay 2 has operated, the motor may be rheostatically braked by moving the controller D to its off " position when the starting resistance r, r<1>, r<2> is connected across the motor armature. When the switch 1 opens the motor field is weakened by an additional field resistance r<6>.

Abstract: 729,871. Obtaining high vacua. LEITZ GES., E. July 14, 1953 [July 18, 1952], No. 19490/53. Class 8 (1). A vessel is evacuated by first filling it with a gas capable of being absorbed and absorbing the gas by an absorbent which absorbs and desorbs the filling gas in a reversible process, the vessel being brought into communication with an auxiliary vessel containing the absorbent when absorption takes place and separated from it when desorption takes place, the desorbed gas being conducted away from the auxiliary vessel. A vessel 1 to be evacuated is connectible to an auxiliary vessel 4 and a vessel 11 by cocks 5, 12 respectively and communicates directly with a vessel 10. The vessel 4 is connectible by a cock 9 to a pipe 8 to a water-jet pump and by a cock 3 to a pipe 2 to a vessel containing hydrogen. A container 6 in the vessel 4 is heatable by means of an electric heating coil 7 and contains titanium powder which when heated to between 350‹ to 550 ‹C. absorbs hydrogen and when further heated to about 800‹ to 900 ‹C. desorbs the gas. The vessel 11 contains getten material (e.g. barium), sufficient to provide several films, by evaporation on the wall of the vessel 11. The vacuum is further improved by gas ionization in the vessel 10. The process of absorption and desorption may be repeated for maximum effect. Palladium vanadium, zinconium may also be used as the absorbent.
