Title: Magnetic tape recording and reproducing apparatus
IPC: G11B5/325
Filed: 1972-07-06
Abstract: 1365232 Recording and playback SONY CORP 6 July 1972 [10 July 1971] 31790/72 Heading G5R A tape recorder includes a system for raising/ lowering a tape guide and a recording playback head along with, or without, a permanently magnetized erase head according as to whether recording or replay is desired. In the arrangement shown, the depression of a button 28, as in Fig. 10, causes a slide 47 to move and so bring a tape guide 63 (described with reference to Fig. 6, not shown), a recording/playback head 53, and a pressure roller 56, all mounted on the slide, into contact with the tape 15 of a cassette 13; simultaneously, however, an abutment 74 on a lever arm 71 which supports a permanently magnetized erase head 52 on slide 47 is engaged by a blocking lever 92, and the arm 71 is thereby forced to rotate in the clockwise sense and so keep the head 52 well clear of the tape 15. Replay from the tape then takes place. If, however, a button 26 is pressed at the same time as 28, as in Fig. 8, a lever 95 is pivoted and causes lever 92 to be rotated so that the abutment 74 on lever 71 is no longer engaged; a torsion spring (73, Fig. 9, not shown) then is able to keep lever 71 and head 52 alongside the guide 63, and the head 52 thereby engages the tape upstream from head 53 for recording operations. The erase head itself comprises a high coercivity low permeability layer 82, Fig. 7, having segments permanently magnetized in alternate senses, as shown, and with a strength which varies from a maximum at 86 to a minimum at 87. The layer 83 is formed of low coercivity high permeability material to trap stray flux. A further embodiment (Fig. 11, not shown ) includes a slot (180) for precisely locating the erase head in the operative position.

Title: Improvements in or relating to the production of polyhydric alcohols by electrolytic reduction of reducible saccharides
IPC: C25B3/25
Filed: 1939-12-08
Abstract: 533,885. Electrolytic reduction of saccharides. ATLAS POWDER CO. Dec. 8, 1939, No. 31844. Convention date, Jan. 7. [Class 41] Polyhydric alcohols, e.g., a sorbitol syrup are produced by electrolytic reduction of a saccharide, e.g., glucose, sucrose, or lactose with an aqueous acid catholyte including the saccharide and an alkali metal sulphate, e.g., sodium sulphate. The catholyte is maintained at pH = 1.5 to 7, most of the saccharide being thus kept under stable acidic conditions whilst that being reduced at the cathode surface is in a solution containing alkali metal hydroxide formed there as a thin layer, by the electrolysis. The cathodes may be of zinc, carbon or graphite, or amalgamated zinc or lead. In an example the catholyte contains 325, 75, and 0.1 gms. per litre respectively of magnesium-free glucose, sodium sulphate, and sulphuric acid, the pH value = 3.6, the temperature 68 F., the anolyte being sulphuric acid of 300 gms. per litre, and the current density 1.10 amps. per sq. dcm. reduced after 50 hours to 0.55.

Filed: 1952-12-16
Abstract: 740,557. Making containers. METAL BOX CO., Ltd. Nov. 24, 1953 [Dec. 16, 1952], No. 31897/52. Classes 83 (2) and 83 (4). [Also in Group XVII] Curling: jointing by stamping.-A method of manufacturing a container with a groove near the mouth and a cap closure for the mouth the edge of which interlocks with the groove but permits free rotation of the cap with respect to the container is characterized by the groove on the container being produced by applying a slip-on tin plate cap 2 having a flared edge 6 to a tubular mouth 3 of the container 1, outwardly curling the flare simultaneously with the application of the cap and then inwardly swaging the curled bead 15 to form the groove 16. The container body may be made from tin plate, aluminium or cardboard and has a perforation 4 near the mouth 3 which by rotation of the cap 2 can be brought to register with a perforation 5 in the cap. The interlocking of the cap on the container body is effected by placing the body in the bore 13 of a die 12 and the cap in a recess of an upper die 7 attached to a ram 14. As the ram moves the die 7 towards a die 8 the cap is applied over the mouth of the container and the flared edge 6 of the cap engages a conical shoulder 13a in the lower die 8. Through the co-operation of said shoulder with a tapered shoulder 11a surrounding the recess in the upper die the flared edge is curled into a bead 15 and the final downward movement of the ram forces the bead inwardly on to the container body and forms the annular groove 16. If the container body is of fibre board it is internally supported during the final swaging operation. The mouth of the container may comprise a perforated end wall integral with the container, or constituted by a disc located in the container, said end wall being covered by a rotatable cap having perforations corresponding to those in the end wall and secured to the container as herein described. Alternatively, the end wall may be formed of imperforated paper or cardboard. The tubular mouth may be provided as a fitment to the end of a non- circular container, e.g. an oval powder-dispensing box or the mouth may be integral with a non-circular container.
