Title: Improvements in or relating to apparatus for magnetically recording sound and for reproducing magnetically recorded sound
IPC: G11B5/86
Filed: 1957-01-24
Abstract: 850,293. Magnetic recording &c. apparatus. TOKYO DENKI KAGAKU KOGYO KABUSHIKI KAISHA. Jan. 24, 1957 [March 29, 1956 (2)], No. 36958/59. Divided out of 850,291. Drawings to Specification. Class 40 (2). A magnetic recording machine has heads mounted on a turntable, which is caused to advance such that the heads scan successive arcuate tracks on a fixed sheet record, and has a reversible motor and two alternatively engageable friction idler rollers, by means of which the turntable may be driven in either direction. The erase heads are mounted on a sub-frame with limited freedom of movement relative to the turntable such that an erase head always precedes a transducing head, regardless of the direction of rotation of the turntable. This enables (a) transducing of " mirror-image " records, such as can be produced by magnetic contact-printing; (b) transducing of " 2-on " superimposed recordings (i.e. " RH and " LH ") on the same record surface. Specifications 794,788, 796,251, 815,147 and 833,266 are referred to.
Patent GB-409837-A (GB)
Title: Improvements in the manufacture and production of chrysene
IPC: C07C2/76
Filed: 1932-12-31
Abstract: Chrysene is obtained by leading indenes or hydrindenes in vapour form over dehydrogenation catalysts at temperatures of 500--850 DEG  C. As catalysts may be used oxides, which are not reduced under the working conditions, of metals of the 2nd to the 7th groups, e.g. of magnesium, zinc, aluminium, titanium, vanadium, chromium, molybdenum, or manganese, or other compounds such as sulphides, silicates, or phosphates of these metals.  The catalyst may be pretreated with carbonaceous gases, e.g. ethylene which deposit lustrous carbon thereon, or with steam, hydrogen, ammonia, nitrogen, or carbon dioxide, and these latter gases may also be used to dilute the reactants.  A high rate of flow of indene vapour should be maintained, and stabilizers such as higher organic bases, phenols, or copper compounds may be added to prevent the formation of polymerization products.

Abstract: 523,228. Making heat exchangers. AHLBORN, AKT.-GES., E. Dec. 29, 1938, No. 37714. Convention date, Aug. 11, 1938. [Class 83 (ii)] [Also in Group XIII] A compound heat-exchanger plate is formed by welding to the opposite ends of a plane plate 1 plates 2 in which are pressed marginal packing grooves 3 and projections 20. The grooves are connected by channels 9 welded to the plate 1 to form a continuous groove around the compound plate. Additional channels 21, Fig. 5, are welded to the plate 1 to form the usual fluid passages between adjacent plates. In making the compound plate, the grooves 3 in the plates 2 are punched or milled out, as indicated in slotted lines in Fig. 2, prior to welding the plates to the plate 1 or, alternatively, the grooves are punched out except for spaced transverse bars 11 which are milled out prior to the welding operation. In a modification, a skeleton plate having the marginal grooves and the channels pressed therein is welded to the plane plate.

[Also in Division D1] In means securing a rotary or angularly movable element, such as a bevel or other gear or, as shown, a cam 10 in a sewing machine feed dog drive, on a hollow shaft end 9, the cam has a cylindrical socket (3) to receive the shaft end and is provided with integral webs 5 radially extending inwardly of the socket for abutment with the circumferentially directed faces of opposed, longitudinally extending, open-ended slots 1 in the shaft end for the transmission of rotary movement, and radially outwardly extending, outwardly bevelled, circular pips 8, of resilient arms 4 integral with the cam, extending perpendicularly from the socket, and rooted at the end wall 6 thereof, snap engage in opposed diametral holes 2 in the shaft to retain the cam axially thereon. The cam is injection moulded of resilient plastics. The webs 5 connect with the root ends of the arms 4. A lever (12) is axially slidable within the shaft to a blocking position in which it engages between the arms 4 to prevent their inward pip-disengaging movement. The lever (12) projects through a diametral slot (7) in the cam 10 and is pivoted at its remote end in a cylindrical block (14) slidable in the shaft. The projecting end of the lever (12) is linked to a bracket (23) of the sewing machine feed dog, so that shaft rotation imparts feed motion to the dog. A collar (19) has dome-headed screws (20) inwardly extending through longitudinal slots (18) in the shaft and engaging an inclined portion (15) of the lever, so that axial movement of the collar causes the lever to pivot and vary the eccentricity of the lever projection in the slot (7) and hence controls stitch size and sewing direction.

Abstract: 1,150,197. Eddy current apparatus. HEENAN & FROUDE Ltd. 18 Aug., 1967 [13 Sept., 1966], No. 38228/67. Heading H2A. In an electromagnetic eddy current apparatus, e.g. brake, dynamometer or slip coupling 3, comprising a stationary field member 81 supporting an annular field coil 83, and a rotor 35 which is rotatable relatively to an inductor member 36, the rotor includes two annular series of pole members 40, 41 disposed radially outwardly of the coil and radially inwardly of the inductor member, the latter includes two magnetically rotated cylindrical magnetic sleeves 61, 62, and an air gap separating the pole members and sleeves is crossed at least three times by a flux path F upon energization of the coil. In the coupling shown the inductor member is also rotatable being the driving member driven by an electric motor 10 although a reverse arrangement is contemplated, and the rotor 35 has a third series of pole members 42 whereby the path crosses the gap four times, such members being magnetically isolated from their carrying magnetic hub 45 by a support ring 52 or welds 44. The sleeves 61, 62 may be of iron and magnetically isolated by using Cu and/or Al for their carrying drum 60 which is driven by the motor quill shaft 15 via a support ring 65 and blades 66 which impel air from cover inlet openings 23 to housing outlet openings 21. Constant speed of the output shaft 18 is effected by control of the field coil energizing direct current which is supplied by a control system and A.C. tachometer generator 109.

Abstract: 1425175 Injection moulding GKN GROUP SERVICES Ltd 20 Aug 1973 [18 Aug 1972] 38537/72 Addition to 1375838 Heading B5A The invention relates to apparatus comprising a series of intercommunicating mould cavities the series having an input end and an output end, wherein a plurality of moulding cycles are carried out, each cycle including providing an empty cavity at the input end, injecting plastics material into the empty cavity and maintaining the injection pressure (except when the mould series is disconnected for introducing an empty mould) so as to take up shrinkage of the material as it solidifies. According to the invention the separate feeding means and injecting means of the Specification may be replaced by either a reciprocable screw (43) Fig. 5 (not shown) or a ram (52) Fig. 6 (not shown) in a heated barrel (51). According to another feature of the invention the apparatus comprises a plurality of series of intercommunicating mould cavities. In the example shown in Fig. 1 a stack of moulds made up of upper and lower elements 16, 17 is held in a tubular guide 10 having a bolted-on cylinder member 11 containing a piston member 12. The piston member 12 is urged downwardly against the action of springs 14 by hydraulic fluid introduced into a space 13. Each mould 16, 17 has, e.g. four cylindrical cavities 20 connected to a central runner 21 by runners 22. Fig. 3 shows a modification comprising mould elements 31, 33 arranged alternately in a stack, the elements 31 having two or more runners 32, and the elements 33 having mould cavities 34. An injection nozzle 36 carries a hot runner arrangement 35 comprising a member 37 with heating elements 38, and a runner passage 40 leading to nozzles 41 arranged to engage runners 32. According to another aspect of the invention the material in the mould cavities is initially cooled by liquid cooling medium passing through the moulds and after substantial solidification of the material, cooled by direct contact with the cooling medium. The shrinkage which occurs after solidification allows cooling liquid to flow through conduits into the spaces between the outer surface of the material and the walls of the cavities. These conduits are of such size as to preclude the flow of plastics material therethrough but to allow cooling liquid to pass upon shrinkage of the solidified material.
