Abstract: 1,270,651. Television. HAWKER SIDDELEY DYNAMICS Ltd. 1 April, 1969 [1 April, 1968], No. 5299/68. Heading H4F. [Also in Division G2] Scanning and recording equipment intended for mounting in an airborne vehicle for obtaining a "thermal" picture of the landscape resulting from the infra-red radiation, comprises a main frame 13 supporting two split paraboloid focusing mirrors 11, 12. A mounting 16 below the frame 13 rotatably supports, between the mirrors, a scanner rotor 15 of square crosssection, each of the four sides being optically polished and serving to reflect the received radiation on to the two mirrors 11, 12. The scanner 15 is rotated about an axis parallel to the fore and aft axis of the vehicle and is driven by a motor 20 and gearing 21 situated at the forward end of the equipment. The mirrors 11, 12 focus the radiation on to an infra-red detector 18, formed by an electrical cell, via a ridge mirror 28. A film transport holder 17 above the mounting 16 has compartments 22, 23 for unused and exposed film, respectively, the film 24 travelling in the direction from front to rear. The signal received by the detector 18 is used through the medium of a converter unit to modulate white light which writes upon the film 24. To this end the scanner rotor 15 is made hollow and provided with an enlarged housing 29 mid-way along its length. A stationary glow tube 30 in one end of the rotor is energized by the detector 18 and the modulated light from the tube is focused by a lens 31 on to a mirror 32 whence it is reflected on to a central assembly of prisms or mirrors 33 which rotate with the rotor. The assembly 33 reflects the light outwardly along four paths displaced at 90 degrees whereby the four light beams transverse the width of the film 24 in succession. A curved guide constrains the film in the area of the housing 29 so that it is curved across its width as shown in Fig. 7 and is thus held in focus.

Abstract: 630,578. Refrigerated show cases. HILL & CO., Inc., C. V. Feb. 24, 1947, No. 5318. Convention date, Dec. 12, 1945. [Class 29] An open-topped refrigerated display case has a storage chamber 4 separated from the display space 2 by a duct 10, through which cool air is circulated, the wall 6 of the' air duct bounding the storage space being made of good heat conducting material, while the wall 8 bounding the display space is apertured to allow the cooled air to pass into the display space. The display case comprises a glass front panel 12 and glass end panels 18, the goods being supported on an inclined perforated shelf 8 spaced above the imperforate conducting partition 6 to form the air circulating duct 10. A baffle wall 28 spaced from the insulated rear wall 22 along the whole length of the case forms an air passage 30 in the upper part of which refrigerating coils 32 are positioned. At the centre of the case the partition 6 has an inclined well 52 communicating with an aperture 48 in the baffle wall 28 and containing a fan 50 which draws air through an elongated inlet 40 above the shelf 8 and through the duct 30 past the cooling coils 32. The cold air passes upwardly in the well 52 and is deflected by a baffle plate 54 towards opposite ends of the case to pass to the goods through the perforations' in the shelf 8. The baffle 54 may be perforated to permit limited flow of air upwardly. Moist air entering the open top is drawn off through the inlet 40. Within the duct 30 inclined deflecting members 56 direct the air towards the aperture 48, these are spaced from the rear wall to allow condensation and defrosting liquid from the coils 32 to drain through an opening 58 to a drain 60. Moisture from the goods passes through a pipe 64 to the drain 60. The storage space 4 is accessible through doors 26. The Specification as open to inspection under Sect. 91 describes also a form in which cooled air is supplied to the storage space through an adjustable opening in the wall 52. This air passes to the display case 2 through openings in the ends of the partition 6. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,260,388. Ultrasonic inspection devices. NEDERLANDS APPLIED SCIENTIFIC RESEARCH FOR INDUSTRY, TRADE & COMMERCE. 31 Jan., 1969 [2 Feb., 1968], No. 5402/69. Heading H4D. In a system for measuring a time interval a mechanical impulse is applied to a test body and a reply signal is received from the body, electrical pulses respectively phase-related to the generation of the mechanical impulse and reception of the reply pulse are generated and applied respectively to set and reset a bi-stable circuit, the bistable output controls the supply of clock pulses to a counter for measuring the time interval, and a delay unit is arranged to delay the start of the counter, in relation to generation of the mechanical impulse, by an adjustable correction time. In the Fig. 1 embodiment, for measuring ultrasonic propagation time (hence wave velocity, which is a measure of the elasticity modulus and material strength) through a concrete specimen, magnetostrictive transmitter transducer A is pulsed by firing thyristor 23 and at the same time generates an electrical pulse (in winding 3) for triggering monostable circuit B and bi-stable circuit C. Piezoelectric receiver transducer D output is applied via amplifier 5, threshold amplifier 6 and gate F to reset the bistable C. Monostable B output blocks gate F while the ultrasonic pulse is being generated, to prevent electrical disturbances from resetting bi-stable C. While bi-stable C is in its triggered state, clock pulses from generator G are fed via gate H to decade counter-tube readout device K. To compensate for the ultrasonic propagation time in members which couple the specimen to transducers A and D, device K is prevented from starting to count until a preset period determined by a further monostable circuit L has elapsed. Circuit details of the apparatus are given.

Title: Inhibition of decomposition of nitrate esters
Inventor: BAUGHAN EDWARD CHRISTOPHER
IPC: C07C201/02
Filed: 1955-02-24
Abstract: Decomposition of low-boiling liquid aliphatic nitrate esters is inhibited during distillation by placing in contact therewith granules or pellets of a chemically inert micro-porous absorbent material with a large surface area, which is capable of removing the decomposition products which tend to form.  Preferably the inert micro-porous material is silica gel.  By this means, for example, ethyl nitrate and isopropyl nitrate may be purified by distillation at or below atmospheric pressure by placing in the distillation flask granules of silica gel of convenient size, e.g. 2 to 5 mm. diameter, and carrying out the distillation in the usual manner.  If desired, a fractionating column packed with granules of silica gel may be included in the distillation circuit for the absorption of gaseous impurities.  The use of porous silica gel also helps to maintain the nitrate esters in a stable condition during storage.ALSO:Decomposition of low-boiling liquid aliphatic nitrate esters is inhibited during distillation by placing in contact therewith granules or pellets of a chemically inert micro-porous absorbent material with a large surface area which is capable of removing the decomposition products which tend to form.
