Title: Preparation of ethylene from petroleum naphtha
IPC: C10G9/14
Filed: 1966-09-16
Granted: 1972-04-17
Abstract: Process for the preparation of ethylene comprises (a) continuously supplying naphtha to a cracking oven, which is operating at a temp. higher than required for cracking naphtha to form ethylene and ethane; (b) separating the ethylene; and (c) continuously supplying a replenishing ethane diluent to the naphtha feedstock, the cracking temp. being so high that ethane is cracked as well as naphtha. In previous methods for the preparation of ethylene by cracking naphtha, the separated byproduct ethane was cracked in a separate cracking apparatus. This had the disadvantage of requiring additional equipment which had to be frequently closed down for coke removal. The present high temp. cracking process is carried out in one apparatus, which requires close downs at much less frequent intervals. In addition, yields of ethylene are improved.

Abstract: 1,234,319. Electric selective signalling; remote control. GENERAL SIGNAL CORP. 29 Sept., 1969 [2 Oct., 1968], No. 47668/69. Heading G4H. In a remote control system the receiver responds to a repeatedly transmitted phase unique binary coded signal, i.e. a signal coded so that the sequence of bits sent when a word is repeated does not contain a sequence representative of any other word in the code, and includes a decoder for recovering the coded bits from the transmitted signal, a shift register into which the bits are loaded serially, a fast shift device for cycling the bits through the register each time a new bit is loaded and a number of decoders each responsive to a particular combination of bits stored in the shift register. Transmitter.-The commands are set up on a keyboard carried by an operator, encoded by a diode matrix and repeatedly transmitted over an F.M. radio link to the receiver. The transmitter is arranged to repeatedly transmit a group of coded signals, each group comprising the coded signal and at least one repeat thereof, at pseudo-random intervals under the control of two multivibrators as long as the input remains the same. When the input is changed the transmission in progress is interrupted and a new transmission started. A deadman's control shuts down the transmitter if the keyboard is tilted more than a predetermined amount. Receiver.-The decoded signal is loaded into a shift register 33 on mark and space leads under the control of clock pulses applied to gates 29 and 30 by a control 28. As each bit is loaded the contents of the register are cycled once via the recirculating loops 31, 32 under the control of high speed shift pulses from the control. Thus the decoder which consists of a diode matrix connected to respective stages of the shift register and enabled by the high speed shift pulses, is given the opportunity of recording any valid code pattern which may appear. If the decoder recognizes a valid code pattern, one line to the temporary store 40 is energized and the corresponding store location is energized when it is enabled by a pulse from a counter 35 which performs a parity check on the cycling signals in the shift register. The " OR " unit 42 then generates a signal indicating that a valid command has been recognized, this signal being gated with the parity pulse and with a pulse indicating that the correct number of shifts have been made in the register 33 to enable the command to be read into the store 41. The store 40 is cleared by the pulse which enables the store 41 after a delay by the delay circuit 38. One of the relay drivers 44 is therefore selected and the command is effected. A check unit 45 checks that the store 40 has been cleared within the allowed time and that the store 41 has also been cleared within a predetermined larger period of time. If the unit detects that these clearances have not occurred correctly, the receiver is shut down. The unit 45 also shuts the receiver down if no commands have been received for six seconds and a particular command has to be sent to reactivate the system.

Abstract: 1,238,170. Flash-bulb. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Sept.24, 1969 [Sept.27, 1968], No.46965/69. Heading G2L. In a flash-bulb having current conductors spaced apart by an insulating member, the member has a recess therein having an ignition mass and the ends of the conductors therein and also there is provided means for keeping a mass of oxidizable metal away from the conductors so that the conductors ignite the ignition mass rather than the metal. In one embodiment the ignition mass 11 comprising zirconium, red phosphorus, potassium perchlorate and lanthanum tin cobaltite in nitrocellulose, is located in the recess 17 of the base of the lamp. The ridge 23 is provided to keep the oxidizable metal 3 away from the ignition mass. In an alternative embodiment Fig.2 (not shown) the ignition mass 11 is located in a recess in a bead (9) which is held inside the lamp envelope by the conductors. In this embodiment and another Fig.3 (not shown) a glass tube (19) may surround the conductors. In another embodiment Fig.5 (not shown) the distance through the ignition mass separating the ends of the conductors is smaller than the distance between the end of a conductor and the oxidizable metal thereby preventing premature ignition of the metal.

Abstract: 1,250,579. Disc &c. brakes. PARK POWERBEAM Ltd. 17 June, 1970 [7 June, 1969], No. 28947/69. Heading F2E. A brake comprises a braking member, at least one friction pad located adjacent the member and arranged to be movable into and out of frictional engagement therewith, first pressure applying means arranged to act on the pad to urge the pad into engagement with the braking member for effecting braking, and a second pressure applying means selectively operable to act on the pad to urge the pad into and out of engagement with the braking mem- -ber thereby to supplement or oppose the braking action of the first pressure applying means. As shown, the brake which may be a disc brake, shoe drum brake &c., incorporates pads 2 bonded to backing-plates 3, 4 and located one on each side of a rotatable disc 1 drivably connected to a vehicle wheel, the plates and a housing 5 being supported on brake supports 7 by guide-rods 6 and so as to be axially slidable relative to the disc. A stepped piston 14 in a correspondingly stepped cylinder 13 is operated by a pressure fluid, liquid or gas, admitted through ports 18 or 19 to respectively apply the pads 2 to the disc or urge the pads away from the disc. Spring clips or Belleville washers 11 disposed about rods 10 secured to the plate 3 act to urge the rods towards the disc and to thereby cause the pads to engage the disc if failure of the brake operating mechanisn causes a reduction in pressure fluid applied to the piston. The pressure fluid introduced into the cylinder may be derived from an automobile engine or a pressure accumulator charged by a hand pump, and should release of the brake disc be necessary during hydraulic failure or servicing a mechanical wedge may effect separation of the disc and pads. More than one piston and cylinder may be provided.

An image of a radio-active source is obtained by localizing the emitted beta particles and X and gamma ray photons, in a gas filled spark chamber. Organic vapour is added to the gas and this is progressively destroyed as the sparks are generated, so limiting the life of the chamber. To limit the dead time of the chamber and increase its life, an external spark quench and control circuit is provided. The control circuit may be designed to cause the chamber to operate in either the spark discharge or electronavalanche condition. In the spark condition, the signal developed at the spark chamber grid is amplified at two avalanche-connected transistors and applied to the grid of a tetrode coupled across the spark chamber to function as a short circuit. Where the spark chamber functions in the avalanche condition the grid signal is amplified before application to the short circuiting arrangement in an amplifier incorporating a wide pass-band, low noise field effect transistor.
