Abstract: 1,008,185. Ventilating cushions. PHILLIPS PETROLEUM CO. Dec. 11, 1963, No. 48895/63. Heading A4M. A flexible ventilating cushion comprises a seat 2a and back 4a portions (Figs. 1, 3, 7) hinged together, as at 3, and each portion 2a, 4a comprises a thin sheet 39 of non-metallic material, e.g. plastics, having spaced hollow, columnar projections 38 extending upwardly from at least one face, the projections 38 being interconnected by web portions 69 integral with the sheet 39, the web portions 69 having perforations 68 therein to prevent air circulation. The cushion includes foraminous covers 10a, 10b bound 26 and stitched 26a at their edges and enclosing the apertured one piece sheet 39. Stiffening frames 150, 151 are movably located within the cushion margin to provide a hinge margin 46 therebetween and a last motion connection. The truncated projections 38 may be vacuum formed from the plastics sheet 39 with stiffening ribs 62 (Fig. 5). The cushion of Fig. 7 may be inverted and the lower cover 10b may be impervious. Ribs 345e (Fig. 14) may be formed in the sheet 139<SP>1</SP> to limit movement of the frame 150. Several layers of plastics sheets, connected only at their edges, may be included as in Fig. 15 wherein two sheets 39 have their projections 38 resting together or (Figs. 16, 17, not shown) wherein a flat perforated sheet reinforces the projection carrying sheet 39.

Abstract: 1,264,013. Pulse modulation circuits; transponder systems. COMMISSARIAT A L'ENERGIE ATOMIQUE. 6 Oct., 1969 [22 Oct., 1968], No. 48922/69. Heading H4L. In a system for remote metering between at least one fixed interrogator-receiver station and at least one transponder, the transponder, Fig. 1a (not shown), transmits a pulse pair spaced by a time interval t representing the input analogue signal Ua, this pulse pair being preceded by a pulse pair spaced by a time interval to representing a reference voltage. The pulses are transmitted as bursts of low-frequency modulating a carrier wave. At the interrogatorreceiver, Fig. 2a, circuit 48 provides timing pulses from the received signal which control the operation of switches 29, 30, 34, 40, 46, switch 46 being an electromagnetic relay and the remainder being field-effect transistors. During the time interval to the switch 30 connects a D.C. source 28 to an integrator 32, 24, 26, the output of the integrator being supplied via switch 34 to a capacitor 38. The voltage across the capacitor 38 is compared in a differential amplifier 41 with the reference voltage supplied from a source 42. At the end of interval to switch 34 opens, switch 46 becomes conductive so that the output of the comparator is supplied via an inverter 43 and switch 46 to the input of the integrator and at the next integration during interval t compensates for any error arising in the transponder due to temperature variations &c. The output Ua is taken from across capacitor 36, which is charged via switch 34, at the end of period t. Switch 29 is closed momentarily at the end of each interval t 0 , t 1 , to discharge the capacitor 26. A plurality of transponders may be interrogated in accordance with a predetermined programme sequence, Fig. 4 (not shown). Each transponder may transmit a plurality of signals simultaneously in frequency or in time division multiplex.

Abstract: 1298661 Proximity fuze HAWKER SIDDELEY DYNAMICS Ltd 1 Dec 1966 [6 Dec 1965] 51717/65 Heading F3A  A fuze device, capable of producing a signal in proximity to a target in response to changes in infrared radiation due to the presence of the target, has optical means interposed between a radiation responsive means and a single field of view which discriminates against radiation outside a selected range of wavelengths and electronic means supplied with signals from the radiation responsive means and which has a frequency band-pass which rejects signals having a frequency below a selected value corresponding to a selected minimum rise-time of the signals. By this means the fuze device is capable of discriminating between the arm and a target. As shown in Fig. 5, the fuse device comprises a base 12 connected to a nose cone 13 and pierced intermediate to length by triangular apertures 14 sealed by a frusto-conical window 22 of calcium aluminate glass. The base 12 also has a bulkhead 15 forward of the apertures 14 which supports a photo-conductive indium antimonide cell 16 within an aperture 17 covered by an optical filter 18. A single shot cooling system 20 also mounted on the bulkhead 15 operates to improve the sensitivity of the cell by cooling it to a temperature of about 40 C. At the rear of the base 12 is an annular powered mirror 21 which focuses radiation admitted through the apertures 14 on to the cell 16 through filter 18. The filter 18 is selected so as to pass only radiation having a wavelength above about 4À2 microns and the window 22 is selected so as to pass only radiation having a wavelength below about 5À5 microns. Within the nose cone 13 and carried on three equiangularly disposed pillars 57 are a number of circular boards of electrically insulating material which carry the electronic means of the fuze device. The electronic means includes a filter having a high-pass, high-slope characteristic designed to cut off signals having a risetime corresponding to frequencies below about 150 c/S so as to provide maximum discrimination between the signal rise rate due to the missile passing a target and that due to the sum and the missile motion. A r.f. filter is provided to ensure that any extraneous radiations picked up are filtered out to prevent faulty initiation of the fuze device. One of the circular boards carries a contact fuze operable on impact to generate a warhead igniting signal. The upper wavelength limit of 5À5 microns imposed by the window 22 may be extended 6À5 by suitably selecting the window material in order to provide greater capability against kinetically heated targets.
