Patent GB-561508-A (GB)
Title: Manufacture of tri-p-anisyl-chloroethylene
Filed: 1942-08-21
Abstract: Tri-p-anisyl-chloroethylene is prepared by treating tri-p-anisyl-ethylene or tri-p-anisylethanol dissolved in an organic solvent with an approximately equimolecular proportion of chlorine. A very slight excess of chlorine, such as 2-5 per cent, may be used, but beyond this amount more highly chlorinated products are formed. Solvents mentioned include carbon tetrachloride, glacial acetic acid, chlorobenzene and nitrobenzene.  In examples: (1) tri-p-anisyl ethylene in glacial acetic acid solution is treated with a solution of chlorine in glacial acetic acid at 20-30 DEG  C. with external cooling if necessary, and allowed to stand at room temperature for 1/2 hour.  A final reflux removes hydrogen chloride and the product is precipitated by the addition of water; (2) a nitrobenzene solution of tri-p-anisyl ethylene is treated with a nitrobenzene solution of chlorine and worked up as in example (1); (3) chlorine gas is passed through an ether solution of tri-p-anisyl-ethylene and the product worked up as before; (4) a carbon tetrachloride solution of tri-p-anisyl-ethylene is treated with a carbon tetrachloride solution of chlorine; (5) a carbon tetrachloride solution of tri-p-anisyl ethanol is treated with a carbon tetrachloride solution of chlorine below 25 DEG  C.; (6) a nitrobenzene solution of tri-p-anisyl ethanol is treated with a nitrobenzene solution of chlorine.  In each of the above examples the product is tri-p-anisyl chloroethylene. Specifications 518,149, 549,200 and 559,374 are referred to.

Title: Communications terminal.
IPC: H04L17/00
Filed: 1968-03-12
Abstract: 1,157,426. Digital transmission systems. INTERNATIONAL BUSINESS MACHINES CORP. 12 March, 1968 [21 March, 1967], No. 11873/68. Heading H4P. A transmitting and receiving terminal for digital data and which is operable in various modes includes first and second registers 13, 17 and a buffer store 15. Data from store 13 passes via buffer 15 to store 17, from buffer 15 to store 13, and from store 17 to store 13, under the control of unit 23. If a polling signal is received from a distant station its arrival in store 17 causes the terminal to transmit an appropriate response, and then to transmit or receive data. Entry mode.-Parallel-bit characters from teleprinter 11 are read in to store 13, which passes each character in serial-bit form to multicharacter magnetic core buffer 15. Print out mode.-Serial-bit data from buffer 15 is read out to store 13 which passes each character in parallel-bit form to the printer 11. Read out is permitted only when store 13 is empty. Transmit mode.-When switched to this mode, the terminal can transmit only after reception of a transmission-requesting polling signal from the distant station. The polling signal passes via units 21, 19 to store 17. Each character received in store 17 is checked to determine whether it is one forming part of a polling signal. If a sequence of characters forming the polling signal is received an affirmative response signal is placed in store 17 and transmitted via 19, 21. The data in buffer 15 is now read out to store 17 and transmitted. Receive mode.-The terminal can receive data only after reception of a reception-requesting polling signal from the distant station. The polling signal is detected, and a response generated, in the same way as described under " Transmit mode ". The distant station then transmits and the terminal receives the data via units 21, 19. Store 17 passes each character to store 13. If the data is low speed it is passed in parallel-bit form direct to the printer, but if it is high speed, store 13 is read out serially to buffer 15 and from thence, at the end of the message or when the buffer is full, to store 13 and printer 11. If the buffer fills, a signal indicating this is sent to the distant station to stop it transmitting. The remainder of the message can then not be sent until the buffer is empty and the distant station has again polled the terminal.

Title: Device for modulating parallel beams of light
Inventor: SHAMBUROV VLADIMIR ALEXEEVICH
IPC: G02F1/03
Filed: 1966-03-18
Abstract: 1,099,972. Modulating light. INSTITUT KRISTALLOGRAFII. March 18, 1966, No 12093/66. Heading H4F. [Also in Division G2- To intensity modulate parallel beams of light 28, Fig. 1, the beams are directed through crossed electro-optic crystals 3 and 4 having electrodes 5 and 6 which are disposed between crossed polarizers 1 and 2 with the result that a konoscopic interference pattern (Fig. 2, not shown), is produced in the focal plane of objective lens 7 by virtue of the fact that the difference in the path lengths of orthogonally polarized rays depends upon their direction in the crystals. A mask 8 is positioned in the focal plane of objective lens 7 between collecting lens 9 and 10, the mask 8 being a photographic negative of the interference pattern so that with no electrical field applied to crystals 3 and 4 the illuminated areas of the real image of the interference pattern are obscured by the dark areas of mask 8. When an increasing electrical field is applied to the crystals 3 and 4 the interference pattern gradually varies until a complementary pattern is obtained which passes through mask 8 so that the entire light flux emerges from the second objective lens 11 in the form of parallel beams 29, the angular divergence of which are equal to that of beams 28. The arrangement may be used for highspeed still or motion picture photography. Fig. 3, in which the beams 30 from the subject pass via polarizer 13 and crossed electro-optic crystals 14 and 15 to a semi-silvered mirror 18 which splits the beam. The two beams are directed through polarizers 19 and 20 and objectives 21 and 22 and reflected by mirrors 23 and 24 on to a film 25 disposed between masks 26 and 27 which correspond to the photographic negative and positive of the interference pattern, one of polarizers 19 and 20 being crossed with polarizer 13 and the other being parallel to it. With no voltage applied to electrodes 16 and 17 of crystals 14 and 15 no light reaches film 25, but with an appropriate electric field applied to the crystals the light passes through masks 26 and 27 to form the real image of the subject on both sides of film 25 composed of two complementary parts corresponding to the transparent areas of masks 26 and 27. For still or motion photography exposure is effected by applying short voltage pulses to electrodes 16 and 17.

Title: Apparatus for maintaining a constant pressure at varying capacity or a constant capacity at variable pressure in a centrifugal compressor
IPC: F04D27/02
Filed: 1957-04-15
Abstract: 822,084. Centrifugal compressors. MASCHINENFABRIK OERLIKON. April 15, 1957 [May 22, 1956], No. 12297/57. Class 110 (1). [Also in Group XXIX] The impellers 3 of parallel centrifugal compressors 1, 2 each feed a conduit 12 via a non- return valve 6, venturi 7 and a valve 8 whilst the pressures p1, p2 across the venturi 7 are taken to an anti-surging control 4 and fed into pipes 13, 14, each incorporating a check valve 10; the control 4 is connected to a throttle valve 5 which varies the inlet section of the impeller ducts. The pipe 13 opens directly into a chamber 30 of a regulating device 16 whilst pipe 14 opens into the same chamber when a hinged closure 23 is unseated, which closure is joined by rods 21 to a pair of spring bellows 17, 18, the interior of the former being open to the conduit 12 by a pipe 15. The force exerted by a spring 24 loading the closure 23 may be adjusted manually or by a motor 29. The interior of bellows 18 is open to atmosphere. With the valves 10 open and the pressure px in pipe 15 below the preset value, i.e. that required to overcome the spring 24, the closure 23 remains seated; when the pressure px exceeds the preset value, the pressure in bellows 17 is greater than that in bellows 18 so that the closure 23 is unseated and interconnects pipes 13, 14 whereupon the pressure difference p1-p2 at the control 4 is lessened due to a baffle 9, and the throttle 5 is adjusted until the pressure px again reaches the required level and the system is in equilibrium. The compressors are thereby controlled to give a constant pressure with a variable capacity. In order to maintain a constant capacity with variable pressure a flow meter 31 is provided in the input to the compressors, the pressures on either side of which are fed to the bellows 17, 18 whilst the pipe 15 is disconnected from the bellows 17. In a modification, the chamber 30 opens to atmosphere instead of the pipe 13.
