Title: Antenna for space vehicle
IPC: H01Q1/08
Filed: 1966-10-24
Abstract: 1,094,424. Aerials. COMMUNICATIONS SATELLITE CORPORATION. Oct. 24, 1966 [Dec. 8, 1965], No. 47642/66. Heading H4A. In a spin-stabilized artificial satellite 10 an aerial system comprising a central rod aerial 13 with a parabolic cylinder reflector 14 is mounted on a de-spun platform 11 carried on low-friction bearings 12, the said reflector being held in its active position (Fig. 1) by means of a spring-biased hinge 16. Should the de-spinning motor stop, so that the platform 11 rotates with the rest of the satellite, centrifugal force will overcome the biasing of the hinge 16, and the reflector 14 will tilt away from the aerial 13 (Fig. 2). The radiation pattern will change from a pencil beam directed to a particular earth station, to an omni-directional mode. An R.F. transparent cylinder 15, made for example of glass fibre reinforced plastics material, may be provided opposite the reflector 14, and be similarly hinged. In a second embodiment, Figs. 3, 4 (not shown), the reflector is constituted by a number of flexible metallic wires (17), made for example of beryllium-copper, mounted on the de-spun platform and having opposite them a number of flexible R.F. transparent wires (18). In a third embodiment, Figs. 5, 6 (not shown), the reflector is constituted by a number of flexible metallic petals (19) which are biased in the active position against an R.F. transparent cylinder (20).

Title: Improvements in Analogue-to-Digital Converters.
IPC: H03M1/48
Filed: 1966-10-24
Abstract: 1,158,991. Selective signalling. BAILEY METER CO. 24 Oct., 1966 [23 Oct., 1965], No. 47736/66. Heading G4H. An analogue-to-digital conversion system in which an input voltage is repeatedly sampled and digitized by comparison with a stepwise increasing or decreasing reference signal produced by a counter, is characterized in that in each digitizing cycle the counter is initially set to the final count achieved in the preceding cycle. The system described also has the feature that each digitizing cycle is automatically terminated after 20 clock-pulses by a subsidiary counter. If the reference signal has not become equal to the input voltage before the cycle times expires, then during the next cycle, the counter which produces the reference signal has its tens denomination incremented. Thus the reference signal then rises or falls in steps ten-fold larger. The direction of variation of the reference signal is determined at the beginning of each cycle from the result of the initial comparison of the input signal and the reference signal.

Title: Arrangement for the production of flocked material
IPC: D04H11/00
Filed: 1962-12-24
Abstract: 975,445. Flocked material. H. J. ROTH. Dec. 24, 1962 [Feb. 26, 1962], No. 48591/62. Heading B2E. An arrangement for the production of material having a flocked surface by the application of fibres to a carrier material comprises an electrode for creating an electric field for directing the fibres on to the carrier material, the electrode being oscillatably mounted, means being provided for oscillating the electrode at a frequency above approximately 500 cycles per second, e.g. between 1000 and 10.000 cycles per second, during the fllocking. The electrode may be of grid-like construction and is so positioned as to direct the fibres from below upwardly through itself and on to the carrier material. The grid may be of lozengeshaped mesh of metal wire. The electrode may be suspended on threads of catgut or insulating synthetic plastic material. The oscillating means may comprise a pneumatic or electromagnetic vibrator, which may be connected to an oscillator the frequency of which is adjustable. The electrode is arranged adjustable in height. The second electrode, lying opposite the first said electrode, is provided for co-operating with the first electrode and for guiding the carrier material, the second electrode being also oscillatably mounted and arranged for being placed in vibration during the flocking. Means are provided for continuously moving the carrier material through the electric field and for continuously supplying fibres for direction on to the carrier material. As shown, fibres 5 from hopper 21 are carried by belt 19 under oscillating electrode 1, superfluous fibres being removed by extractor 22. Fibres 5 are lifted from belt 19 and directed through the mesh of electrode 1 into the field between electrodes 1 and 2, on to adhesive layer 4 which has been applied to carrier 3 by applicator 25, the flocked carrier being subsequently coiled on roller 27. Electrode 1, suspended by threads 6, is oscillated by rods 10 driven by vibrator 13. Electrode 2, which is in contact with carrier 3, is oscillated by vibrator 17. The carrier may be a woven, knitted, or profield material, e.g. of synthetic plastic. Provision of adhesive may be avoided if the fibres can be secured directly to the carrier, e.g. by exchanging appropriate chemical groups of the fibres when flocking a carrier of suitable synthetic plastic material.

A thermoelectric assembly comprises an aluminium heat exchanger pressed against a junction bridge of a thermocouple and prestressing the semi-conductor elements of the thermocouple, the heat exchanger being thermally and electrically connected to the junction bridge but not forming a significant part of the current path. In a first embodiment, Fig. 1A and Fig. 1B (not shown), a sub-assembly comprises two annular bismuth telluride bodies 211 and 212 of opposite thermoelectric types soldered to a nickel-plated copper junction bridge 213 and to two annular end plates 214, 215 of the same material. A plurality of such assemblies are arranged on opposite sides of pipe sections 216, 217 which form bridges between the end plates of the oppositely positioned assemblies. The pipe sections are connected by insulators 218 to form a fluid flow conduit. Aluminium heat exchangers, in the form of pairs of tubes provided with fins 222, are placed in contact with each of the junction bridges 213 and the assembly is compressed by means of stainless steel bolts 221 acting between insulating members 224, 225. In a modification, Fig. 3 (not shown), the pipe sections (216, 217) are replaced by copper tubes extending coaxially with the compression rods between the ends of the upper and lower sub-assemblies. The copper tubes are provided with external fins, which may be tapered in cross-section. In a second embodiment, Fig. 2 (not shown), a single line of sub-assemblies are connected in series by further bridge members which are soldered across, or are pressed against, the end plates of adjacent assemblies. Aluminium heat exchangers are pressed against each bridge member. If the further bridge members form pressure contacts to the end plates the surfaces may be treated with a gold flash over silverplating. The junctions between the semiconductor bodies and the junction bridges may also be pressure contacts, the surfaces of the bodies being provided with a nickel plating, silvering, and a gold flash. The semi-conductor bodies may be held in position by a plastic frame. In a modification, Fig. 4 (not shown), each sub-assembly comprises a pair of blocks of semi-conductor material joined by a disc shaped junction bridge and having rectangular end plates. The further bridge members are also disc-shaped, and the heat exchangers comprise a finned single tube clamped against each bridge. In a further modification, Fig. 5 (not shown), the further bridging members and their associated heat exchangers are replaced by pipe sections connected by insulators to form a fluid conduit. In another modification, Fig. 6 (not shown), pipe sections extend transversely to the assembly and form bridges between the ends of each sub-assembly and corresponding ends of a second series of sub-assemblies, inverted relating to the first series, the bridge members of which are also contacted by finned aluminium heat exchangers.

Title: Electrical transmission line
IPC: H01B5/02
Filed: 1972-10-24
Abstract: 1380815 Waveguides; conductors INTERNATIONAL BUSINESS MACHINES CORP 24 Oct 1972 [27 Dec 1971] 49067/72 Headings H1A and H1W The frequency of operation and temperature of the conductors of a transmission are arranged so that transmission takes place in the "anomalous spin effect" (ASE) region, the thickness of the conductor being such that its impedance is less than that of the thick film impedance. The ASE region is defined by # 0 /l < 1 where l is the intrinsic electron mean free path and # 0  is the classical skin depth given by :- where c is the velocity of light and l is the intrinsic resistivity. For any given metal #.l = coast.. The curves shown are for aluminium and show the effect on surface resistivity R s  of film thickness t at room temperature and at a temperature # 4À2‹ K. wherejl = 0À01 cm. The three low-temperature curves relate to three values of surface roughness expressed in terms of the fraction p of electrons specularly reflected at the surface of the conductor (p = 1 relating to a perfectly smooth surface). The left-hand portions of the curves exhibit the Fuch's size effect according to which R increases at t decreases. Between this region and the thick film ASE region a transition region exhibiting R min  appears. The phenomenon is explained in terms of the violation of Ohm's Law on the thin film region and a full theoretical account is given in the Specification. The invention is applied to strip lines, coaxial lines and waveguides.

Title: Multi-Passage Collimators
IPC: G01T1/164
Filed: 1967-10-31
Abstract: 1,160,609. Making collimators; jointing. PICKER CORP. 31 Oct., 1967 [14 Nov., 1966], No. 49519/67. Headings B3A and B3V. [Also in Division H5] In manufacturing a multi-hole collimator, the flat external surfaces of a number of lead tubes are coated with adhesive, the tubes assembled with their longitudinal passages arranged substantially parallel to one another to form a honeycomb structure which has two end surfaces formed by the ends of the tubes and which substantially fills a supporting frame, and the adhesive is cured to bond the tubes together. The tubes are preferably of the same length, may be formed by impact extrusion, and thus may have one closed end, which closed end may be removed after curing by machining one or both end surfaces. One of the end surfaces may be shaped so as to have a concave cross-section so that it can be placed adjacent a corresponding convex input window of an image intensifier. The end surface may be shaped approximately to the desired crosssection by causing the assembled tubes to slide axially relative to one another prior to curing for distances such that the end surface approximates to the desired section, and after curing, machining the end surface to the desired section. To maintain the tubes in position during curing, a forming plate which abuts one of the end surfaces may be clamped to the supporting frame. In machining the cured assembly, the frame and the honeycomb structure are rotated about a central axis substantially parallel to the longitudinal axes of the tubes and a cutting tool is moved along a radius of each end surface so as to give that surface the desired cross-section after which the frame and honeycomb structure are rotated while the cutting tool is moved along a radius to give the same cross-section as previously, but the direction of rotation of the honeycomb structure relative to the cutting tool is opposite to that which occurred previously. Preferably, the radial movement of the cutting tool is from the perimeter of the end surface to its central axis. The tubes may be orientated in the frame and simultaneously coated with adhesive by means of a brushing action. After curing, interstices between the tubes are filled with an adhesive material mixed with a radiation absorbing material, and the honeycomb structure subsequently heated to harden the adhesive. The tubes used preferably have a hexagonal cross-section. If desired, during milling, the tubes are strengthened by being filled with a material which is subsequently easy to remove, e.g. paraffin wax.
