Abstract: 1378289 Coating method; coating lenses by evaporation BUTLERS Ltd 22 March 1972 [3 April 1971] 8625/71 Headings B2E and B2L [Also in Division C7] Lenses of vehicle lamps coated by engaging the lens with a recessed support member so that the lens closes the recess, with the surface to be coated outermost, the periphery of the lens engaging the periphery of the recess so that the opposite surface is masked and moving the support member relative to a spraying device so that the whole of the lens surface is presented thereto during a spraying operation. The term "spraying" includes vacuum deposition. Part of the lens surface may be masked with a detachable mask before the coating operation. In the Figure a lens 11 moulded in a transparent synthetic resin material is shaped to conform to the shape of the bodywork of the vehicle with which it is to be used and supported by support member 14 in the form of a hollow, thin walled container formed from a sheet of synthetic resin material. The shape of the support member 14 is such that the lens can be engaged in the open end thereof so as to close the recess. The support member retains the lens as a push fit within the support. Each support member is so shaped that the exterior surface contains a groove which can engage a bar 16. A plurality of support members 14 each carrying a lens are engaged with a single bar 16 and are spaced apart along the length of the bar. Six of the bars, thus loaded, are engaged with a common carrier 17 consisting of a pair of members 18 at opposite ends of a common shaft 19. At its free end each of the arms carries a spring clip and each bar 16 has one end received in the spring clip of an arm of one of the members 18 and its opposite end received in a spring clip of an aligned arm of the opposite member 18. The bars are thus rotatable above the axis of a shaft 19.

Title: Improvements in or relating to direct current electric motor systems
Inventor: DALE SAMUEL HOWARD
IPC: H02P3/08
Filed: 1956-03-22
Abstract: 806,978. Control of D.C. motors. GENERAL ELECTRIC CO. Ltd. June 24, 1957 [March 22, 1956], No. 9006/56. Class 38 (3). A D.C. motor I is connected through a reversing switch 3 to a supply 2 which comprises an inverter and a rectifier operating in parallel. Rheostatic braking is introduced by closing switch 5 to connect resistor 4 across the armature of the motor. Closure of the switch also renders the D.C. supply to the motor non- operative, and the phase of the grid control potentials of the inverter is then advanced at a controlled rate so that the inverter returns power to the A.C. supply for the gradual introduction of regenerative braking. In another arrangement, a single converter is adapted to operate both as a rectifier and as an inverter to supply power to and receive power from the motor. The reversing switch 3 may be coupled with the switch 5. Specification 601,633 is referred to.
Patent GB-493101-A (GB)
Title: Improvements in the treatment of antitoxins and the like
IPC: C07K16/06
Filed: 1937-03-30
Abstract: Toxins, antitoxins, antivenoms, bacterial antigens, antibacterial serums and the like are purified by subjecting them, together with the proteins with which they are normally associated, to digestion with a proteolytic enzyme, such as pepsin or trypsin, until about 70 per cent of the proteins have been destroyed or rendered non-coagulable by heat, and thereafter filtering and treating the resulting solution with tricalcium phosphate or other insoluble alkaline earth or magnesium phosphate in finely divided form to adsorb inactive proteins, lipoids, and enzyme from the solution.  The digestion, which is preferably conducted at a pH above 4, removes proteins other than the pseudo-globulin carrying the active anti-substance, and this is preferably precipitated from the solution and redissolved before treatment with the phosphate.  This precipitation may be a salting-out with ammonium sulphate or other neutral salt, preferably after concentration of the solution by ultrafiltration, and the solution obtained by redissolving the precipitate is preferably dialysed through a regenerated cellulose membrane before addition of the phosphate.  The digested serum may also be concentrated by dialysis and evaporation.  The phosphate is removed by filtration and the final solution concentrated by ultrafiltration.  The initial serum or the like may be moderately heated to precipitate fibrin, which is filtered off before the enzymatic digestion.  The process may be applied to antitoxin previously purified by the usual fractional salting-out with ammonium sulphate.  Numerous antitoxins, antivenoms and other anti-serums are specified; a detailed example relating to the treatment of diphtheria antitoxin being given. It is stated that in the case of toxins the process serves also to detoxify them, with the formation of the toxoids.  Specification 468,676 is referred to.  The Specification as open to inspection under Sect. 91 refers also to the use of lithium phosphate, and to concentration of the digested solution by absorption.  This subject-matter does not appear in the Specification as accepted.
