Title: Target image motion detector
IPC: G01S3/787
Filed: 1962-04-26
Abstract: 936,287. Radiation choppers. BARNES ENGINEERING CO. April 26, 1962 [May 25, 1961], No. 16003/62. Class 40 (3). [Also in Group XL (c)] An instrument comprises a radiation detector, a reticle and mask combination, optical means for imaging a target on to the plane of the reticle, all in optical alignment, the reticle and mask combination including a moving reticle formed of bands inclined to the direction of reticle pattern movement at supplementary angles separated by areas transmitting the radiation, two reference signal generators operating in synchronism with the movement of the reticle cyclic pattern one producing a signal at pattern cycle frequency (p.c.f.) and the other a signal at one-half p.c.f., two rectification means actuated by a respective reference signal generator, and electric circuits including limiters interposed between the radiation detector output and rectification means inputs, whereby the rectification means produce signals proportional to the departure of the target image from a centre position in the mask aperture in two orthogonal directions. The reticle may be a moving band, Fig. 3, but in the preferred embodiment is a pattern of Archimedian spirals 14, Fig. 2, on a rotating disc 4 which carries also marks 18 producing a reference signal at p.c.f. and marks 16 producing a reference signal at one-half p.c.f. Detector 6, Figs. 1 and 4, corresponds to a narrow, and detector 8 to a wide field of view. Normally switch 23 is in the position shown, but image presence in the narrow field of view causes actuation of relay 25 which changes-over switch 23 and reverses signal phase in limiter-amplifier 24; and switches 29, 30 are changed-over to allow for the greater collecting power of the narrow angle viewer. The operation of units 27, 28 to produce error signal outputs for azimuth and elevation misalignment is described with reference to Figs. 5, 6 and 7 (none shown). In the application of the invention to tracking rockets, lead sulphide detectors are used to sense the infra-red radiation from the flare of the rocket engine; visible or ultra-violet radiations may also be sensed. The error signals may feed a computer associated with a rocket guidance system, in which case the apparatus of Fig. 1 is manually aimed and the signal outputs are transmitted by cable to the utilization means. To eliminate uniform background the aperture edges may be shaped as described in Specification 898,205.

Filed: 1949-06-16
Abstract: 683,026. Gas turbine plant. ROLLS-ROYCE, Ltd., Sept. 14, 1950 [June 16, 1949], No. 16123/49. Class 110(iii) A fuel system for an aircraft having a gas turbine power plant burning volatile liquid fuel, has the fuel vapour from the storage tank conveyed in vapour form from the tank to the combustion equipment of the engine. In the arrangement shown liquid fuel is fed from the storage tank 15 to the main burners 19 by means of a pump 16. Vapour from the top of the tank is led through a pipe 22 to a second set of injectors 23. The vapour is pressurised by an engine-driven compressor 21. Alternatively, the vapour may be led to an injector 23a in the exhaust assembly of the turbine, in which case the compressor 21 may be omitted. To increase the pressure difference between the tank and the exhaust assembly the exhaust assembly may be constricted as at 13a to cause local acceleration of the gas stream. A flame trap 28 prevents back fire into the fuel tank and a shut off valve 24 to control the supply may be provided. The valve 24 may be manually operated but is preferably arranged to be operated by the pressure difference between the fuel tank and atmospheric pressures. A modification in which the vapour is supplied to a reheat chamber between two turbines is also described. In another modification, the vapours are delivered into the air intake of the compressor which may be provided with a local constriction similar to that in the exhaust pipe described above. The vapour injected in this manner may act as an anti-icing liquid.

Title: Improvements in or relating to method and apparatus for recording sound waves
IPC: H03G7/00
Filed: 1947-06-19
Abstract: 634,586. Sound-recording apparatus. SOUNDSCRIBER CORPORATION. June 19, 1947, No. 16199. Convention date, June 12, 1939. [Class 40 (ii)] [Also in Group XXXIX] In an apparatus for recording sound on a track having a progressively decreasing linear speed such as the spiral track on a disc rotating at constant angular velocity, the attenuation of the higher frequencies which occurs at the lower track speeds is compensated by subjecting the sound signals to a distortion in which the ratio of the amplitude of the higher frequencies to that of the lower frequencies is progressively increased to an optimum value determined by the limit of ability of the stylus to follow accurately the steep wave-fronts at the higher frequencies, and then either widening the said higher frequency band without further increase of the said ratio of frequencies, or continuing to increase said ratio but recording at a lower level. In the embodiment described with reference to the Figure, the required attenuation is obtained by varying the amount of negative feedback in an amplifier A2 by means of a variable frequency-discriminating network 26, 27 which is connected in shunt with a feedback resistance 18, and which is mechanically coupled to the carriage supporting the recording head 5.

Title: Improvements in or relating to laminates
Inventor: CARLISLE SAMUEL SKIPTON
IPC: B32B15/08
Filed: 1960-05-11
Abstract: 906,414. Coated metal. BRITISH IRON & STEEL RESEARCH ASSOCIATION. April 27, 1961 [May 11, 1960], No. 16604/60. Class 140. A moving metal strip is coated with a heat-curable adhesive, the strip is heated to cure the adhesive, a uniform layer of mixed plasticized and stabilized thermoplastic resin is applied to the adhesive coating, the coated strip is then passed under a heated roll, the temperature at this point being sufficiently high to melt the thermoplastic powder on the entry side of the nip without causing adhesion at the exit side, the pressure of the heated roll being insufficient to deform the metal but sufficient to maintain a pool of molten thermoplastic at the entry side, the coated strip is partially cooled and passed under a roll to provide the desired surface finish. As shown, a steel strip 12 is passed through an alkaline degreasing bath 14 and then to a washing device 16 comprising water sprays 17, 18 and squeegees 19. It is then passed through a bath of hot water 20, and squeegee rolls 22 to the adhesive applicator device 23. This comprises a roller 24 in fixed bearings dipping into a bath of adhesive, e.g. an uncured phenolformaldehyde resin, nitrile rubber and sulphur, the layer of adhesive picked up by 24 being passed via roller 27 to roller 28 which applies it to the metal strip. The thickness of the adhesive layer is controlled by roller 29 mounted in movable bearings. The strip then passes to a drier 30 and furnace 31 when the temperature is raised to about 250‹ C. to cure the adhesive. It then passes to a powder applicator 32 comprising cooled rolls 33 and 34 so mounted that powdered thermoplastic material, e.g. polyvinyl chloride, can pass steadily through the gap between them through a vibrating sieve 38 and on to the heated strip. The coated strip carrying the powder passes through heated rolls 39, 40, the upper one 39 being made of polytetrafluoroethylene to prevent sticking and the lower one 40 of silicone rubber, and then to a second heated polytetrafluoroethylene roll 41 which can be rotated at any speed in either direction and supported on a silicone rubber roll 42. The roll 41 maintains a pool of molten plastic at the entry side of the nip, and overflowing is prevented by polytetrafluoroethylene side-guides 43. After leaving the nip the coated sheet is allowed to cool, passed beneath a finishing roll 44 and after further cooling wound up on a coiler 45. The Provisional Specification describes a different form of powder applicator.

Filed: 1969-03-31
Abstract: 1,246,921. Pallet loaders. BRITISH MATHEWS Ltd. 26 March, 1970 [31 March, 1969], No. 16633/69. Heading B8C. Pallets are withdrawn from a magazine 4 and, while supported on a vertically movable support 8, are loaded with layers of articles fed alternately from layer assembly platforms 14 and 16. Rows of articles for making up the layers are assembled on platforms 80 and are transferred by drag bars 86 on driven bands 84 to the rollers 18 which make up the layer assembly platforms. Continuous belts 70 engage and drive the rollers 18, and the leading rollers 15 are raised by arms 17 to prevent premature discharge of layers on to a stripper plate 12. Pivoted beams 30 and 32 push the layers from the assembly platforms on to the stripper plate and are mounted at the ends of a carriage 20 which is reciprocated in tracks 22 by a gear 38. When the carriage moves to withdraw a beam to the outer end of an assembly platform, the beam is raised to clear the layer on the platform by the action of a cam track 42 or 52 on a beam roller 40 or 50. After the beam is freed from the rear end of the track, reverse movement of the carriage causes the beam to advance the layer of articles on to the stripper plate 12 which is then withdrawn from the shaft 6 so that the layer is transferred to the pallet in the shaft. A loaded pallet is withdrawn from the stack by chains 10 which also draw the next pallet from the magazine. Operation of the apparatus is so synchronized that as a layer is completed on one assembly platform, half a layer has been assembled on the other platform. Means may be present for adjusting the orientation of articles presented to the platforms 80 so that a bonding pattern may be provided between layers on the pallet.
