Abstract: 1389831 Recording system EMI Ltd 16 Feb 1972 [24 Feb 1971 20 July 1971 5 Aug 1971 1 Dec 1971 23 Dec 1971] 5293/71 34000/71 36746/71 55662/71 and 59896/71 Heading G5R Apparatus for recording information on a medium comprises a leading element for preparing the medium, e.g. by grooving or planing and coupled thereto a second element incorporating a laser for deforming the prepared surface in response to the information. As described, the medium is a recording disc and the information can be in the form of a frequency or amplitude modulated signal. The recording disc which can be a lacquer layer 2 on aluminium base 21 is prepared by a leading element (not shown) which forms the grooves 5 of such depth that the ridges 4 are below the original surface. The second element includes the laser 25, the beam 24 of which acts on the medium via a Pockel cell which modulates the beam with the information to be recorded. The ridges 18, 19, 20 of the record are deformed by the laser beam such that when a positive record is formed the deformations lie at the bottom of the grooves. Alternatively the beam can deform the groove base directly. The elements are coupled and are moved relative to the record along paths parallel to a record radius, Fig. 3 (not shown), and arrangements are provided, Figs. 6-8 (not shown), for focussing and maintaining the focussing of the laser beam. Sufficient depth of focus being provided to maintain the beam intensity constant over the cutting or deforming depth. A stream of nitrogen can be used to disperse the particles removed from the record surface. The record can be played back by a stylus or an optical sensing transducer.

Title: Improvements relating to radio-receiving apparatus
IPC: H03G3/26
Filed: 1953-02-25
Abstract: 720,756. Radio receiving circuits. GENERAL ELECTRIC CO. Feb. 25, 1953 [March 1, 1952], No. 5298/53. Class 40 (5). In a muting circuit a unidirectional control voltage proportional to signal strength is applied to a gas discharge tube 25 in series with a resistance 26 and negative bias source 27, so that when the signal is of a predetermined strength the tube 25 conducts. The sudden flow of current in resistance 26 then removes the bias from a valve 32 which conducts and causes a relay 35 to close contacts 37 completing the loud-speaker circuit. As shown, the arrangement is applied to a frequencymodulation receiver, the control voltage being derived from a resistance 21 and smoothing condenser 22 connected in the anode circuit of a limiter 7.

Title: Improvements in or relating to agricultural machines, implements or the like
IPC: A01D78/08
Filed: 1949-03-02
Abstract: 691,526. Agricultural machinery. NICHOLSON, A. C. July 4,1949 [March 2, 1949], No. 5670/49. Classes 6(i) and 6(iii) [Also in Group XXXII] Relates to agricultural machines, such as tedders mowers, seed-sowers and groundworking implements which are trailed behind tractors. According to the invention, these machines are mounted on wheels, some or all of which are castors the swivelling of the castors being prevented during transport but permitted during normal working. As shown in Fig. 1, the structure 1 is mounted on castors 6, 7 and a fixed wheel 5 and is towed by the tractor 2 through a draught connection 3. In normal use, the castors swivel freely, but for transport, Fig. 2, the structure is towed sideways and the wheels 6, 7 are constrained to rotate in planes parallel to the line of draught, the wheel 5 being transferred to an alternative axle 9. The arrangement may be applied to a framework 20 normally supported on tractor liftlinks through a three-point connection 25, 26, 31. For towing the frame endwise, a further bar 39 is provided and rest-bars 42 may support the opposite end of the frame while the tractor is uncoupled. The position of the upper hitch-point 36 of the three-point support may be adjustable by the lever 33 and quadrant 32 shown in Fig. 15. Additional wheels, either fixed or castor, may be arranged on the frame to stabilize it during transport. The castor-wheel construction is shown in figure 25. The wheel 215 rides in a fork 216 carried by a vertical shaft 218 keyed to a sleeve 219. The sleeve is rotatable in a socket 212 bolted to the machine frame 211. Integral arms 222 and 223 on the sleeve and socket respectively are securable together by a pin 224 to restrain the wheel from castoring. The keyway permits raising and lowering of the wheel by means of a handle 228 voked to the shaft 218. The additional castor-wheels may incorporate spring-mountings to support the frame floatingly, and a modification, Fig. 28 (not shown), is described wherein the frame is suspended by springs from lift-arms on the tractor.

Abstract: 1,043,004. Generators operating by electromagnetic interaction with fluids. COMPAGNIE GENERALE D'ELECTRICITE. Feb. 11, 1964 [Feb. 13, 1963]. No. 5761/64. Heading H2A. A magnetohydrodynamic generator comprises two combustion chambers Ch1, Ch2 and ducts T1. T2, enclosed in the same refractory housing R and subjected to the same transverse magnetic field wherein the working fluid flows in opposite directions in the two ducts. Coolant flows in passages in the duct walls in the same direction as the working fluid in the adjacent duct. The coolant comprises the fuel for the combustion chambers and coolant for G1 is injected into combustion chamber Ch2 of generator G2 and similarly the fuel supply for G1 is the coolant of G2. The generator output may be controlled by varying the volume of coolant flowing. Since the generators have substantially identical currents flowing in opposite directions in the same magnetic field, " armature reaction ' " effects are eliminated and the electrodes E of each generator may be connected in series to double the output voltage if the generators employ the Hall effect.

Abstract: 920,251. Plate heat-exchangers. C. A. PARSONS & CO. Ltd. Jan. 26, 1960 [Feb. 19, 1959], No. 5790/59. Class 64 (3). Plate apparatus for heat exchange between fluids in counterflow is made by assembling sections 1, Fig. 3, cut from a plane sheet and sections 5, 6 from a corrugated sheet of mild steel. As indicated by step A of Fig. 3, the stock plane sheet has, at one longitudinal edge, a member 2 secured by brazing or tacked for brazing when the apparatus is assembled. A section 5 of the corrugated sheet is located on a section 1 of plane sheet as shown by step B and a further section 1 of the plane sheet is inverted to complete a pair of plane sheets, as shown by step C, with the corrugated section 5 between in the flow channel thus formed. The stock corrugated sheet has members 4, similar to the member 2 of the plane sheet, at both longitudinal edges. The sections of the plane and corrugated sheets are obtained by transverse cutting of the stock sheets. A larger section 6 of the corrugated sheet is added in step D and the building-up process is continued with corrugated sections 6 separating successive pairs of plane sections and forming second flow channels therebetween. Dimensions of the components are given. One fluid is led to one edge of each section 6 and flows along the corrugations between the edge members 4 to the opposite edge. This flow may be between rectangular headers welded or brazed at each side of the apparatus. The fluid flowing through the pairs of plane sections 1 is introduced from tubular headers 9a, Fig. 6, one welded or brazed at each end of the apparatus, and flows to the spaces between the edge members 2 at one side of the apparatus, along the corrugations of the sections 5 to the corresponding spaces at the opposite side to be collected in headers 9b. The headers 9a, 9b may each be formed, as in Fig. 4a, by a tube 9 cut away at intervals along its length and each cut-away portion may accommodate an element consisting of a stack of flow channels. If a notched header 9 is not used the complete stack need not be divided into elements. The Provisional Specification refers to Specification 718,991.
