Abstract: 771,922. Radio receiving apparatus. PLESSY CO., Ltd. Feb. 11, 1955 [Feb. 11. 1954], No. 4033/54. Class 40(5) A tuning device, particularly for use in a television receiver, comprises two sets of coils having adjustable tuning cores, means for setting the cores of one set of coils to tune to a fixed frequency, means for continuously varying the tuning of the other set of coils and a switch actuated by the last mentioned means so as to switch the continuously varied coils into circuit over the greater portion of its tuning range and to switch the preset coils into circuit at one end of the range. The device comprises a first set of coils 6, 7, 8 mounted on the upper surface of a chassis 1 and comprising tuning cores 9 attached to a common bar 11 by threaded rods 10. The bar 11 is slidably mounted in openings 12 and is urged by springs 13 against cams 15 mounted upon a rotatable shaft 14. By adjusting the position of the shaft 14, the tuning of the coils 6, 7, 8 may be preset to a selected frequency, the shaft 14 being retained in this preset position by means of a locking screw 35. The springs 10a are provided to prevent vibration of the rods 10 with consequent variation in the tuning of the coils 6, 7, 8. The tuner also comprises coils 16, 17, 18 which are supported horizontally on the underside of the chassis 1, their ends being supported within rubber grommets 19. The cores of the coils 16, 17, 18 are connected by threaded rods to a cross-bar member Fig. 2 (not shown), the cross-bar being coupled by a rack and pinion drive to shaft 26 whereby the position of the cores within the coils 16, 17 and 18 may be continuously varied. A plurality of switches 28 is also mounted on the underside of the chassis 1, the switch rotors being mounted on a common shaft 29 on which is also mounted a member 33 co-operating with a member 32 mounted on the shaft 26. With the shaft 26, member 32 and member 33 in the position shown, the coils 6, 7, 8 are connected into circuit and the tuner is set to receive upon the frequency determined by the setting of the shaft 14. On rotating the shaft 26 anti-clockwise the member 33 is turned through a small angle whereby the switches 28 are operated to switch the coils 16, 17, 18 into circuit, so that for the remainder of the anti-clockwise movement of the shaft 26, rotation of the shaft 26 varies the frequency to which the tuner is set as determined by the position of the cores of the coils 16, 17 and 18.

Patent GB-1031041-A (GB)
Title: Hydrocarbon cracking process
IPC: C01B3/38
Filed: 1963-02-04
Abstract: In a process for the continuous cracking of a sulphur-containing hydrocarbon which has a final boiling point of about 200 DEG  C., cracking being performed in the presence of water vapour on a nickel catalyst, product gas is recycled and mixed with the hydrocarbon feed in an amount dependent on the boiling range of the hydrocarbon and on the H2S partial pressure that would have arisen in the catalyst zone in the absence of recycled gas, so that the product gas has a predetermined calorific value for a given reaction temperature.  The required amount of hydrogen is determined experimentally.  The process protects the catalyst, and enables the amount of water vapour used to be diminished. Oxygen or air may be used in the reaction. Three examples, in which a light gasoline is cracked, are described.

Title: Electrical control circuit arrangement for lifting-magnets
Inventor: TRUNINGER PAUL
IPC: B66C13/18
Filed: 1964-02-03
Abstract: 1,055,034. Control systems for lifting magnets. TRUNINGER A.G. Feb. 3. 1964. 4445/64. Heading H2H. A system for controlling the energization of a lifting magnet has the winding 10 of the magnet permanently connected to the output of a rectifier 4 supplied from a three-phase source over a main switch 1 and a contactor 2. Reverse energization of the winding 10 is provided by a transformer 12 and rectifier 18. When it is desired to drop the load on the magnet contactors 2 and 11 are opened and contactors 16 closed. The collapse of the magnetic flux in the winding 10 produces a voltage which bucks the voltage from the rectifier 18 so that initially a relay coil 21 remains de-energized. As the voltage due to the collapse of the flux decreases the relay coil 21 becomes energized to close contacts 24 thereby applying reverse energization to the magnet winding 10. When the reverse energization reaches a predetermined value a relay 8 is energized sufficiently to cause its contacts to make thus to effect opening of contactors 16 so switching off the reverse energization of the winding 10. The pull-in point of relay 8 may be adjusted by means of a variable resistor 28.
