Title: Improvements in or relating to processes for the electrolytic polishing of metals
IPC: C25F3/20
Filed: 1953-06-30
Abstract: 746,772. Electrolysis. EVER READY CO. (GREAT BRITAIN), Ltd., and TURNER, H. L. May 28, 1964 [June 30, 1953], No. 18146/53. Class 41. An electrolyte for anodic polishing of aluminium or aluminium-rich alloy comprises 70 to 80 per cent by weight ortho-phosphoric acid, up to 10 per cent by weight of organic reagents comprising 2 to 5 per cent by weight of diethylene glycol monoethyl ether or ethylene glycol monoethyl ether and 5 to 8 per cent by weight of diethylene glycol or ethylene glycol, and 20 to 10 per cent by weight of water. A preferred composition comprises 77 per cent ortho-phosphoric acid, 3 per cent diethylene glycol monoethyl ether, 7 per cent diethylene glycol and 13 per cent water. An aluminium salt, e.g. 1.5 per cent AlPO 4  may be added. In polishing a torch case, the case is cleared in a mild alkali and then immersed for 30 to 60 seconds in the composition which is heated to 60‹ to 100‹ C. The case is then connected as anode and D.C. at a voltage of 7 to 25 applied, a current density of 120 amps. per square foot of anode surface being preferred. The electrolyte is agitated, e.g. by air. The cathodes, which may be of lead or graphite, should have a greater surface area than the case, e.g. six times as great. The process continues for 2 to 20 minutes, when the case is removed and swilled in water. The thin aluminium oxide film is removed by a liquid composition, e.g. caustic soda, a mixture of chromic and phosphoric acids, a mixture of chromic and sulphuric acids, or solutions of the salts of these acids. After further swilling, the case is subjected to anodic oxidation, e.g. in sulphuric acid, to provide a protective film, which may be dyed and sealed in hot water. During the polishing process, the electrolyte is passed through a bed or column of cation exchange material, e.g. one containing sulphonic acid groups, to maintain the aluminium content of the electrolyte at the desired low level. Specification 704,953 is referred to.

Title: Actuating device in a motor vehicle equipped with an engine- exhaust brake
IPC: F02D9/04
Filed: 1974-04-25
Abstract: 1472796 Controlling fuel supply to vehicle engines DAIMLER-BENZ AG 25 April 1974 [2 May 1973] 18178/74 Heading B7H [Also in Division F1] A system for controlling the fuel supply to a vehicle engine comprises a fuel-injection pump 3 having a regulating rod 25 movable in response to the action of a governor 29 and to the pivotal movement of lever 26 fast with lever 2. Movement of the latter is effected by operation of an accelerator pedal connected to that lever via a piston and cylinder assembly 5 and a lever arrangement 6 which, when the pedal is released, is held against a stop 22 by action of a return spring (24) (Fig. 3, not shown). The assembly 5 comprises a piston 9 movable against bias of spring 8 by exhaust gases entering via port 12 when an exhaust brake is activated, and a rod 11 connected to the lever 2 and biased by spring 10 to the illustrated position within piston 9. When the accelerator pedal is released and the exhaust brake is applied, the arm 20 will abut stop 22 and the piston 9 and rod 11 will be retracted together within the cylinder until the level 2 attains its stop position II. The position 9 then moves alone to abut the end of the cylinder. If the accelerator pedal and the brake are operated at the same time, the lever 2 will still be held in its stop position. When the brake is released and the accelerator pedal 1 is depressed the lever will move from its no-load position I towards a full-load position III. In the event that the vehicle overruns the engine, and the pedal 4 is in its rest position, governor 29 will pivot lever 27 to move rod 25 to zero delivery stop 25a and subsequently bring lever 2 to its full load position III. Actuation of the exhaust brake will cause the lever 2 to be moved towards its stop position II.

Title: Improvement in sound re-recording method and system
IPC: G03B31/00
Filed: 1940-12-30
Abstract: 548,557. Gramophone recording circuits. RADIO CORPORATION OF AMERICA. Dec. 30, 1940, No. 18220. Convention date, Dec. 29, 1939. [Class 40 (iv)] In re-recording arrangements, the original record is reproduced by a variable gain amplifier during one or more trial runs, the volume being controlled by a manually adjustable control current which is recorded and may be used in subsequent trials in which the control may be further modified, the actual re-recording being effected under control of the recorded control current when a satisfactory rendering has been obtained and a record of the control being taken for use in the automatic control of volume during the actual re-recording. When the recorded matter of a number of original records is mixed for re-recording, the above described arrangements are applied to control output from each record. As shown in Fig. 1, the variable gain amplifier 16 is controlled during a trial run by a voltage derived by rectification of amplitude controlled current from oscillator 26 over switch 27. The control is effected manually at 25 as judged by reproduction in loud-speaker 21 and the amplitude of the control frequency is magnetically recorded at 30, switch 31 being closed. A further trial run mav be made under automatic control by throwing switch 27 to connect up the control frequency reproducer 33. The control record may be erased during this run and re-recorded from the reproducer 33 by keeping switch 31 closed and varying the control 25 to correct unsatisfactory parts of the record. When rerecording by mixing the outputs from a number of records, separate control frequencies or separate records may be used to control the outputs. Disc records may be used for control current and the sound record may be a film, disc or magnetic record.

Title: Production of thermoplastic films and apparatus therefor
IPC: B29C48/90
Filed: 1961-05-23
Abstract: 972,556. Making tubular films. MONSANTO CO. May 23, 1961 [May 23, 1960], No. 18529/61. Heading B5B. A tubular film of organic thermoplastic material 2 is produced by feeding the material in a flowable condition from the forward end of an extruder 1 to a die 3 having a circular extrusion orifice through which the material is extruded to form a tube which is inflated by the introduction of air or other gas at superatmospheric pressure to form an inflated tubular film 10. This continues to expand until it comes into contact with the unpolished outer surface of the inner metal wall 6 of the cylinder 4. The inflated tubular film is then drawn upward through the cylinder 4 in adjacent relationship with the wall 6 as indicated at 11. The jacketed cylinder 4 is coaxial with the die 3 and comprises an outer wall 5 and an inner wall 6 between which is an annular space 7 through which a cooling fluid, preferably a liquid, is passed by means of pipes 8 and 9. When the film 10 emerges from contact with wall 6 at 12 it has been cooled to the ambient temperature. Cooling of the film is effected by heat transfer through the inner wall 6 of the cylinder 4, which wall may be of metal, graphite, a fluorocarbon plastic or a methacrylate. When the wall 6 is of metal the surface contacting the inflated film is left unpolished to facilitate the sliding of the film over the surface. The apparatus may be used for the manufacture of polyolefine films. The extrusion orifice of the die may be square, hexagonal or elliptical in shape, in which case the cross-section of the inner wall of the cooling cylinder must have the same shape.
