Title: Improvements in or relating to television receivers of the superheterodyne type
IPC: H04N5/44
Filed: 1939-02-07
Abstract: 524,776. Wireless receiving apparatus ; television. KOLSTER-BRANDES, Ltd., and SMYTH, C. N. Feb. 7, 1939, No. 4020. Drawings to Specification. [Classes 40 (iii)] and 40 (v)] A television receiver adapted to receive more than one vision carrier frequency comprises an intermediate frequency amplifier with means for adjusting the selective circuits to a plurality of predetermined frequencies or with a plurality of pre-set tuned circuits, and is so arranged that the frequency to which the intermediate frequency amplifier is tuned is suited to the received carrier frequencies. In this way interaction of harmonics of the local oscillator with harmonics of the incoming sound and vision frequencies may be avoided without elaborate screening. The intermediate frequency amplifier for the accompanying sound signal may be simultaneously adjusted in frequency so as to permit the use of a common mixer valve for both sound and vision channels. The Specification gives details and a chart for selecting frequencies when receiving programmes on 45“ Mc. or alternatively on 54“ Mc.

Title: Improvements in or relating to circuit arrangements for operating rotary selectors in telecommunications installations
IPC: H01H67/06
Filed: 1957-02-07
Abstract: 824,395. Automatic exchange systems. SIEMENS & HALSKE A.G. Feb. 7, 1957 [Feb. 7, 1956], No. 4225/57. Drawings to Specification. Class 40 (4). The circuit of a motor-driven rotary selector which steps over groups of contacts in response to a digit and hunts within the selected group is so arranged that the nth pulse is absorbed if the nth group of lines is dead. The lines of groups (n - 1) and (n+l) are wired to consecutive contacts, the contacts of group n and (n+1) all being available for lines of group n. A number of pulses, not necessarily consecutive, may be absorbed from one digit. When the switch reaches a rest contact at the beginning of a contact group such as the nth corresponding to a dead group of lines a mechanical contact operates a relay to disable the motor for the period of the impulse. If the impulses to be absorbed are consecutive, a stepping relay is used to absorb them.

Title: Improvements in electric control apparatus
IPC: H02P7/00
Filed: 1924-02-27
Abstract: 232,380. White, A. E., (Socony Burner Corporation). Feb. 27, 1924. Electrically controlling fuel and air supplies. -Relates to an electric control arrangement for liquid-fuel burners which require to be started and stopped according to changes of temperature in a room. An electric motor 64 switched in by a thermostat contact 77 operates switches 30, 42 which respectively put in action a sparking-plug 4 in the burner 1 and an additional motor 16a for driving a fan 17 and a pump 8 supplying air for combustion and atomizing purposes respectively to the burner. The motor 64 controls its own circuit by rotating a brush 70 over four contact plates 72, 73, 74, 75 grouped in the form of a ring. Two of the plates are electrically connected to opposite contacts of the thermostat, a third plate is connected to a switch 93 responsive to hot-gas pressure from the burner, and the fourth plate 74 is connected to the motor 64. In normal operation the motor 64 is cut-out when the brush 70 comes on the contact plates 72, 75, since the gas-pressure switch 93 will be open and the thermostatic switch will not have made contact on the " warm" side. Accordingly, after stoppage of the motor, the switches 30, 42 remain closed, keeping the burner in action. When the thermostatio switch subsequently makes contact on the "warm " side, the motor 64 is restarted through the contact plate 72 and stopped after moving the brush on the plate 73, the switches 30, 42 being thereby opened and the burner put out of action until such time as the thermostatic switch makes contact on the " cold " side. Intermittent action of the burner will continue in like manner to keep the room between given limits of temperature. Abnormal action will arise in case the burner fails to work, since the absence of hot gas pressure in a chamber 90 will close the switch 93 and make connection to the plate 75, which, upon the arrival of the brush 70, will keep the motor 64 running until the brush advances to the next position 76, thereby opening the switches 30, 42. A pushbutton switch 100 allows a restart to be made from this position. Specification 238,912 is referred to.
