Title: Improvements in or relating to information display systems
Inventor: MULLARKEY ALFRED JOHN
IPC: G09G1/16
Filed: 1966-02-11
Abstract: 1,120,751. Cathode-ray tube displays. STANDARD TELEPHONES & CABLES Ltd. 11 Feb., 1966, No. 6092/66. Heading H4T. The occurrence of a predetermined amplitude relationship between each sample of a sequentially and cyclically sampled plurality of signal sources 1 and a sawtooth wave from generator 9 (recurrent at the sampling rate under control of generator 4) produces, via comparison means 8, a trigger pulse which is utilized to control the intensity or focus of the beam of a cathode-ray tube deflected vertically by the sawtooth from 9 and horizontally by a second saw-tooth wave generator 11 synchronized by one stage of a control arrangement 3 for the sampling switches 2. The trigger pulse from means 8 may operate to de-focus the beam, to switch it on or, to vary the brightness of the existing spot. Alternatively, the trigger pulse may be employed to trip a bi-stable device to its second state in which the beam is blanked, the device being returned to its first state on the occurrence of the fly-back of the sawtooth from generator 9 or, on the occurrence of a predetermined level in the trace portion of such sawtooth. The signal sources may be e.g. thermocouples attached to the heater tubes of a power station, pressure transducers or depth gauges and ready identification of a particular signal input corresponding to a particular (vertical) line scan may be realized by blanking one or more of the latter (not corresponding to a signal input) by means of pulses from outputs of device 3 (not employed for control of switches 2) so that the display lines are divided into groups. Deviation of the signal inputs from the norm. may be deduced by comparing the display with a master drawing or graticule or, in the case where the bi-stable device is returned to its first state by the occurrence of a predetermined level in the trace position of the sawtooth wave, from the display itself. E.H.T. is derived via a diode from the flyback scan energy in amplifier 10 which supplies the line sawtooth from generator 9 to the vertical deflection means.

Title: A tool for driving pins, rivets or other fastening elements
IPC: F15B11/04
Filed: 1957-02-22
Abstract: 834,293. Explosively-actuated pin driving tools. SCHULZ, W. Feb. 22, 1957 [Feb. 23, 1956(2); April 24, 1956], No. 6097/57. Class 119 [Also in Group XXIII] An explosively-actuated pin driving tool incorporates means for causing the pin to be elastically intercepted so as to limit the penetration of the pin into a wall or other part. In one form pin interrupting jaws 3, Fig. 1, are secured by a spring clip 4 to a member 17 axially slidable on the barrel 1. Before firing a sleeve 2 with its shutter guard 14 is pressed forwardly to retain the jaws 3 in the closed position so as to intercept the pin 5 on firing. If the pin 5 is driven into soft material, the jaws 3 will be entwined therewith together with the member 17 thus compressing a spring 20. The spring 20 may be replaced by a rubber spring or an air cushion. In another embodiment, Fig. 3. the propulsive effort acts on a piston 22 in which is located a collet-like chuck 23 for holding the pin head 27, the chuck 23 having a reduced front end 26 of less diameter than that of an opening 29 in the end of the barrel. On firing into hard material, a strong rubber ring 31 absorbs the momentum of the piston 22 when or just before the pin reaches its full depth of penetration. In this position, only the reduced end 26 of the chuck 23 will have entered the opening 29, and the jaws can open and permit the tool to be withdrawn. If, however, the pin is driven into soft material, the larger diameter of the jaws would enter the opening 29 and he retained thereby in the closed position, and at the same time a strong spring 32 is compressed to limit the penetration of the pin. In a further construction use is made of a gas cushion created by compression of the explosion gases. Inside an outer barrel 51, Fig. 4, is a second inner barrel 52 enclosing a main chamber in which a driving piston 54 can slide. The piston 54 is screwed into a metal block 57 slidable in the barrel 51, which block transfers the momentum of the piston to a pin connected to the block as described with reference to Fig. 3. Rods 60 connect the block 57 and hence the piston 54 to an annular piston 59 which slides in the space between the two barrels. On firing a cartridge in the chamber 55 the explosion gases propel the piston 54 and block 57 to the left to drive the pin into the wall. As soon as the rear end of the piston 54 reaches ports 61 in the barrel 52, the gases escape into the space between the barrels 51, 52. The ports 61 are then immediately closed by the annular piston 59 further forward movement of which compresses the gases and hence the further forward movement is braked. Embodiments are also described, Figs. 5. 6 (not shown) in which the braking spring or gas cushion for the pin is used to exert an extractive pull on the pin after firing thereby to test the strength of its anchorage in the wall.

Abstract: 496,018. Cathode-ray tubes. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. March 2, 1938, No. 6571. Convention date, March 5, 1937. [Class 39 (i)] An iconoscope screen comprises a " signal " layer deposited on a mica or other dielectric, or a dielectric layer of alumina, magnesia, silica or the like on a metal plate, the layer of sensitized mosaic particles, and a " braking " layer of aluminium, platinum, gold or chromium covering the voids between the particles which has a lower capacity of emitting secondary electrons than the dielectric and which does not electrically connect the sensitive particles. The " braking " layer must be thick enough to prevent the scanning electrons reaching and exciting the dielectric and sufficiently thin to have a large resistance. The " braking " layer should not be oxidized to a depth of more than 20 atoms and may, in the case of aluminium, be 100 atoms thick. It may be deposited on the dielectric layer, either before or after the sensitive particles have been deposited, by vaporizing from tungsten wire in an exhausted space. It is stated that if the braking layer extends under the sensitive particles it prevents them coalescing during manufacture.

Title: Improvements in or relating to the production of alkyl chlorides
IPC: C07C17/093
Filed: 1944-04-12
Abstract: Alkyl chlorides are prepared by reacting gaseous hydrogen chloride with a sulphuric acid ester of an acyclic aliphatic alcohol containing not less than three carbon atoms in the molecule in the presence of water in an amount of not less than 8 per cent by weight calculated on the total sulphuric acid present in said ester or esters and as the free acid, if any, at a reaction temperature between room temperature and 60 DEG  C.  It is preferred to use sulphuric acid esters containing less than a molar proportion of alcohol per mole. of acid since free sulphuric acid accelerates the reaction.  The spent liquids remaining after removal of the resulting alkyl chlorides may be reacted with acyclic aliphatic olefines having at least three carbon atoms to reform sulphuric acid esters which may be reacted as above with hydrogen chloride.  A cyclic process comprises absorbing such olefines in sulphuric acid containing at least 8 per cent of water, treating the resulting alkyl sulphuric acid esters with hydrogen chloride, removing the alkyl chlorides formed and repeating the cycle with the spent liquor obtained.  In examples: (1) secondary butyl alcohol is reacted with aqueous sulphuric acid yielding a mixture of sulphuric acid esters containing 16.3 per cent water and the mixture is treated with hydrogen chloride to form secondary butyl chloride; (2) propylene is absorbed in aqueous sulphuric acid and the resulting ester solution containing 11.3 per cent water treated as above giving isopropyl chloride; (3) the spent liquor from (2) is treated with further propylene and the resulting sulphuric esters treated as in (2); (4) n-butene is absorbed in 79 per cent sulphuric acid and the above-mentioned cyclic process carried out yielding isobutyl chloride.  Amyl chloride may also be prepared by these methods.  Specification 566,174 and U.S.A. Specification 2,284,467 are referred to.  In the Provisional Specification the process is not limited as regards temperature.
