Title: Improvements in Means for Cooling and Conveying Metal Sheets
IPC: B65G25/00
Filed: 1968-08-01
Abstract: 1,199,829. Cooling and conveying metal sheets. SCHLOEMANN A.G. 1 Aug., 1968 [29 Aug., 1967], No. 36720/68. Addition to 1,117,963. Heading B8A. Apparatus for cooling and conveying metal sheets, as described in Specification 1,117,963, is modified in that inclined guides 27 on the under side of longitudinal supports 10 are provided with a horizontal portion y between inclined portions x and z. The guides are supported by rollers 28. By longitudinal movement of the supports 10, support members 5 for the sheets become level with stationary support members 4 when the rollers 28 are in contact with the portions y of the guides 27. This positioning can be carried out with sufficient accuracy with a polyphase motor driving a crank-shaft (23), Fig. 1 (not shown). The inclination of the portions x produces a more rapid raising and lowering of the support members 5 than the lesser inclination of the portions z, the former movement being appropriate for the members 5 when unloaded and the latter being more suitable for the members 5 when supporting their load. The reduced inclination of the portions z permits a motor of lower power to be used. In place of the electric motor an hydraulic cylinder drive may be used.

Abstract: 1,018,030. Moulding processes. PHILIPS ELECTRONIC AND ASSOCIATED INDUSTRIES Ltd. Sept. 8, 1964 [Sept. 11, 1963], No. 36738/64. Heading B3F. A moulding process comprises coating a pattern with a layer of a fine-grained refractory and a binder, applying a layer of coarse-grained refractory thereto while still wet, allowing the layers to dry, then wetting the dry coated pattern with a binder and arranging it in a mould box and packing with a granular refractory and allowing said second binder to solidify, then removing the pattern. The pattern may be coated with a release agent such as petroleum jelly or silicone grease. The first coating layer may be zirconium silicate, aluminium oxide or aluminium silicate, with a silicic acid sol as binder, applied as an ethanolic suspension and hardened by the action of ammonia, by spraying with e.g. an aqueous solution of ammonium acetate, or by heating. The coarse-grained refractory may be aluminium silicate. The second binder may be a silicic acid sol, albumins, sodium silicate solutions and methyl cellulose, and the back-up material may be moulding sand. A surface-active substance such as sodium dodecyl naphthyl sulphonate may be added to the binder to promote wetting of part of the backing material thereby. Solidification of the second binder may be initiated by adding a coagulating substance to the back-up refractory or to the binder.

Abstract: 1,099,868. Selective signalling. STANDARD TELEPHONES & CABLES Ltd. Aug. 17, 1966, No. 36812/66. Heading G4H. In a non-linear analogue-todigital converter covering the range 0-1024 (negative inputs being inverted before being digitized and a sign digit made equal to 0) first the particular one of eight ranges or octaves, 0 to 8, 8 to 16, 16 to 32, 32 to 64, 64 to 128, 128 to 256, 256 to 512 and 512 to 1024, in which the input lies is ascertained and represented by three bits, referred to as the " octave number," and secondly, the position of the input within its octave is determined linearly, accurately to three bits referred to as the octave position." Thus in the first octave 0 to 8, each increment in the octave position corresponds to a unit increment in the input, whereas in the eighth octave, 512 to 1024, each increment corresponds to an increment of 64 in the input. The octave number is determined by a series of eight units C2A, S2A; C2B, S2B; C2G, S2G; Fig. 1 (the first stage C1 is merely a sign stage), each of which firstly provides an output, on a lead labelled " OR," indicating whether its input V is larger than 512, and secondly an output of 2(V-512) on a lead labelled " 1 " if V>512, or an output of 2V on a lead labelled " 0 " if V<512. Thus the input signal applied to stage C2A, S2A will pass sequentially along the series-being doubled at each stage-until eventually, one stage has an input larger than 512. This stage then produces a " 1 " bit on its " OR " lead, which by means of three " OR " gates, OR 2, OR 3 and OR 4, produces three bits indicative of the octave number, subtracts 512 from its input, and passes twice the difference to a conventional three-bit digitizer C5, C6, C7, each unit of which produces either 2V, if V<512 or 2(V-512) if V>512, where V is its input, to provide three bits indicative of the octave position. In a first modification designed to produce a reflected binary output, the transfer characteristics of the units C5, C6 and C7 are changed to l V-512 l, , all V, and in a second modification the transfer characteristic of the units C2A &c., are also changed V-512 all V.

Abstract: 1,045,519. Making electrical connections. AMP. Inc. Sept. 3, 1965, No. 37643/65. Heading B3A. [Also in Division B8] Lengths of insulated wire W are engaged in a conveyer 1 and each wire is brought into alignment with a continuously rotating coarse positioning wheel 6, whereupon the conveyer is stopped. The wire W enters between a pair of fingers 7 on the wheel periphery (Fig. 3, not shown), and opposite the wheel is a wire endsensing device (Fig. 4, not shown). The wire enters the device causing the fingers 7 to close over the wire which is then pulled through the sensing device until a bared end comes under a leaf spring and a microswitch is then opened and the wire released from the periphery of the wheel 6. The conveyer resumes its advance and the wire is passed to a fine-positioning wheel 21 which operates in conjunction with a sensing device as previously described. The conveyer 1 then advances the wire to a crimping station 22 where a connector T is crimped thereto. Alternatively, the wire may be fed axially into the crimping station. If a connector is required on the other end of the wire, it is passed to a wheel 23 which positions it roughly and then to positioning wheels 6<SP>1</SP>, 211 and crimping station 22<SP>1</SP> which operates as described previously. The wire is then deposited in a bin 24 by the conveyer 1. In an alternative embodiment the positioning wheels may be replaced by pairs of oppositely rotating drive rolls.

Title: System for calling a ground station from an aircraft
IPC: H04L15/26
Filed: 1974-08-29
Abstract: 1471349 Calling ground station from aircraft DE STAAT DER NEDERLANDEN TE DEZEN VERTEGENWOORDIGD DOOR DE DIRECTEUR GENERAAL DER POSTERIJEN TELEGRAFIE EN TELEFONIE 29 Aug 1974 [4 Sept 1973] 37725/74 Heading H4L In a system for calling a ground station from an aircraft, in which the ground station automatically monitors radio calls from aircraft which transmit and receive over one of a predetermined number of high frequency carriers, a tone frequency calling code signal is transmitted from the aircraft over any one carrier, and separate receivers for all the high frequency carriers are provided at the ground station. A decoder is connected to all the receivers to identify a completely and correctly received calling code signal for the ground station over any one carrier. When a calling code is identified the transmission of traffic signals over the carrier is enabled. There are eight tone frequencies available ranging from 660-2340 Hz and by pairing them together, each being transmitted for a 1 sec. period, 56 code signals are available and identify particular required ground stations. These codes are modulated on to one of six allocated carriers in the range 4-22 MHz selected by the aircraft pilot in dependence on distance, season, time of day &c. and the modulation may be ordinary amplitude modulation or SSB. The transmitted signal is received by one of the units 1-12 depending on frequency and form of modulation. The transmitted code is determined in a decoding and switching apparatus 26 and contains two parts (a) in formation identifying the called ground station of (b) the direction of the aircraft from it, the form of modulation and a particular terminal served by the station. A received message passes via remote control apparatus 27, 28 and line 29 to a switching apparatus 30 which routes it to the desired terminal, either via main control or other control stations 31, 32. The apparatus 30 sends a signal via 33, 35, 34 to a switching apparatus 36 and thus to the ground station transmitter 37, to adjust it to the appropriate frequency and modulation ready for the return call. The transmission frequency is determined in accordance with the receiver which received the code. The part of the code concerned with direction is used to set the position of aerial 38. The switching apparatus 36 also controls, through 40, 42, 41 and switch 26, the aerial switches 22-25. These are normally oscillating, but must be stopped at the desired direction and frequency. The full code signal (Fig. 2) incorporates a first part in which two distinct frequencies together identify a particular ground station are thrice repeated and a second part in which four distinct frequencies, identify direction, modulation technique and particular called customer are thrice repeated.

IPC: G06V30/224
Filed: 1960-11-03
Abstract: 916,315. Automatic character reading. REUMERMAN, T., and HELMIG, W. H. T. Nov. 3, 1961 [Nov. 3, 1960], No. 37853/60. Class 106 (1). In recognition apparatus characters, Fig. 3, modified by slots in two out of five possible positions are sensed by two groups of magnetic reading heads 21-33 and 22-32, Fig. 4, the first group being adapted to scan the five code positions 3, 5, 7, 9,11, Fig. 1, together with the top and bottom positions 1 and 13 and the second group scans the six intermediate positions 2, 4, 6, 8, 10, 12. All heads are connected to binary stores 41, 42, &c., a store being set when a black part of the character is sensed. A properly printed and aligned character causes five out of the seven stores in the first group 15 to be set and all the six stores in the second group 16. Test circuits 17, 18 check that these conditions are present and that of the first group of stores the top and bottom ones are set. Any out-of-alignment or defect in the character is thereby detected to reject or mark the character. Otherwise the five significant digits from store 15 are read out by unit 20 and passed by gate 19. In the form of Fig. 5, there are three groups of seven sensing heads 55, 56, 57 arranged in staggered relationship. The associated stores 58, 59, 60 are connected to accommodate some vertical out-of-registry of the character a particular five of one of the groups being set by the code elements according to the position of the character. Two groups may in practice both sense and store the code elements, but the other one (or two) storage groups will be all black. Circuits 61, 62, 63 test for a valid combination of signals and if the first store is found to have a valid combination the signals are gated out by gate 64 and the other two output gates 65, 66 are blocked. The circuits 61, 62, 63 also check that at least one store has six consecutive elements set. The stores may alternatively be shift registers, the stored patterns being shifted vertically to bring them to the register position. Specification 845,510 is referred to.
