Title: Improvements in change-speed gear control
Filed: 1945-02-05
Abstract: 598,592. Controlling change-speed gearing. CLEVELAND, F. J. (Bendix Aviation Corporation). Feb. 5, 1945, No. 2881. [Class 80(ii)] A single-acting vacuum-shift motor 20, controlling two ratios of either a two-speed overdrive rear-axle or of a main three-speed transmission of a motor-vehicle, without main-clutch operation, shifts to the higher ratio when a three-way manually- or electrically-operated selector-valve 48 is operated to communicate engine-manifold suction 56 with its working-chamber 64 and the engine accelerator-pedal 74 is subsequently (or previously) released to unload the meshed low-ratio gears e.g. 14, 18, for neutralising and synchronising the gears e.g. 14, 16 to be meshed for the high-ratio; a return down-shift being effected by the load of an internal or external spring 22 when the selector-valve 48 is operated to vent the working-chamber 64 and the accelerator-pedal 74 is first released to unload the meshed high-ratio, for neutralising, and subsequently depressed to speed the engine and synchronise the low-ratio. In the overdrive axle shown, the shiftpinion 14 constantly meshes a driving wheel 10 and is shifted axially into mesh with the low- and high-ratio wheels 18, 16, through a lever 36 upon which this vacuum motor may act in the high-ratio direction only, through a spring 82 which yields to allow the lever to lag behind the motor until the wheels 14, 16 synchronise as the engine slows down following accelerator-release. The selector-valve 48 may be a simple-valve controlled by a push-button 58, or its suction and vent ports may be controlled by a pair of solenoids energised by a pair of manually-operated bush-buttons (Fig. 4, not shown). The change-speed gear may be provided with synchronising and balkmeans, but is preferably not so provided, although the teeth of the gears 16, 18 and the splines of the sliding-gear 14 are preferably so shaped as to prevent mesh until synchronised. The vehicle may be provided with a main friction or fluid clutch.

Title: Improvements in or relating to methods for the treatment of meltable material in rod-shaped form by zone-melting
IPC: C10L1/06
Filed: 1961-01-25
Abstract: 894,739. Zone-melting. PHILIPS ELECTRICAL INDUSTRIES Ltd. Jan. 25, 1961 [Jan. 28, 1960], No. 2941/61. Drawings to Specification. Class 32. In the formation of a monocrystalline rod of silicon having a protective film of silicon monoxide by zone-melting in an atmosphere comprising oxygen, a molten zone is passed from one end of the polycrystalline rod into a monocrystalline seed joined to the other end and back to the first mentioned end. The rod may be supported in a crucible or at each end only. The passage of the molten zone in the first direction may be through a gas-liquid surface layer, the cross-sectional area of the zone being gradually increased to its maximum within the seed on reversal of direction. Heating may be by a surrounding induction coil. Initial formation of the molten zone at the end of the polycrystalline rod spaced from the seed ensures that irregularities in the initially formed silicon monoxide film affect one end only of the resulting monocrystalline rod, which end may be cut off from the rest of the rod.

Abstract: 1,099,902. Stamping. FREDERICK A. KRAUSE ASSOCIATES, Inc. Jan. 22, 1965 [Jan. 27, 1964], No. 3017/65. Heading B3Q. [Also in Division Fl] An hydraulic intensifier for movable die-holder members 12, 14, Fig. 1, of a sheet metal press comprises a double-acting compressed air operated piston 48 supplied from an accumulator 58 and connected by a rod 50 to a piston 52 serving to pressurize oil in a cylinder 44 to which make-up is supplied from a compressed air loaded reservoir 62 through a duct 64, an annular cavity 68 in a housing 46 separating the two cylinders 42, 44 and through slots 76 loading to a bore 74, Fig. 2, in the piston 52 when the latter is in its retracted position; supply and exhaust of air to and from opposite sides of piston 48 being controlled by a rotary valve 60 which is reversed by a solenoid 102 when energized by the momentary closing of a micro switch 104 by the piston 48 in its fully extended position. During return of pistons 48, 52 solenoid 102 remains energized and for a period of say 30 seconds after the completion of stroke by means of a thermal delay and relay device thereby allowing time for cylinder 44 to be filled and pressurized by compressed air admitted through valve 60 to the reservoir 62. Solenoid 102 is then de-energized and the forward stroke serves to supply pressure oil through ducts 34 to pistons 26, 28 in holders 12, 14. In operation and assuming a sheet of metal (138), Fig. 5 (not shown), to have been positioned in the press which is then closed, piston 26 forces a die 16 against a die 22 which retracts a piston 28 to its lowermost stop position in holder 14. Full pressure is then transmitted to the upper die holder 12 and piston 26 which are moved upwardly relative to die 18 which continues to descend thus producing two sequentially performed bends in metal sheet. Die element 24 is urged upwardly by further hydraulic pistons (not shown) and has a concave groove for curling the edge of the metal sheet. As die holders separate during opening of the press die 24 rises whilst die 16 descends.

Title: Improvements in thread spools and the method of constructing the same
IPC: D05B57/28
Filed: 1940-02-19
Abstract: 537,444. Spools of thread etc.; moulding plastic materials. MARINSKY, D., and MORIN, L. H. Feb. 19, -1940, Nos. 3136 and 3137. Convention dates, March 21, 1939 and June 1, 1939. [Class 120 (iii)] [Also in Group V] A spool of thread &c. is made by cross winding the material on a core with the material exposed at the sides thereof and coating the sides with a thin layer of wax or like material which extends from the core to the outermost windings of the spool and form the flanges thereof constituting the sole support and cover for the material at the sides of the spool. The colour of the wax &c. may be the same as that of the thread &c. or the flanges may be of different colours. The wax or like flanges retain the windings against accidental unravelling and, as the thread &c. is unwound from the spool, it is lubricated at spaced intervals by the wax ; the flanges may be provided with grooves or other weakened portions to facilitate the breaking up of the flanges as the thread is unwound. As shown the flanges 13, 13a, Fig. 1, are formed by dipping the spool 12, Fig. 5, on a core 11 supported by a spindle 26 in a bath of molten wax 19 and then withdrawing the spool from the wax and rotating the spindle to throw off the surplus wax and give the flanges a convex form; the flanged spool is then pressed in a cooled die to impress the wax with grooves or other markings and is finally stripped from the spindle for reversal and a second dipping to form the other flange. In another arrangement the flanges are formed by spraying the ends of the spool while carried by a slowly rotating spindle and then rapidly rotating the spindle to throw off the surplus wax &c. The flanges may be grooved, either circularly or spirally or be provided with circular and radial grooves. The wax may be contained in a pan 49, Fig. 13, pivoted to a container 47 so that it may be lowered thereinto and receive a quantity of molten wax to a definite level and the spindle 52, after dipping the spool 40 into the wax, may be moved away and then lowered to dip the spool a second time; the spindle is then rotated and a scraping or grooving tool 53 moved beneath the lower surface of the flanged spool to form the grooves in the flange.

Title: Improvements in the reproduction of photographic multicolour records
IPC: G03C7/00
Filed: 1941-03-10
Abstract: 549,141. Colour photography. TECHNICOLOR MOTION PICTURE CORPORATION. March 10, 1941, No. 3222. Convention date, Nov. 15, 1940. [Class 98 (ii)] In a process of reproducing by contact or projection a multicolour original record, or a set of colour record images, on multilayer sensitive material, of the kind in which the contrast of at least two of the colour component images is changed by subjecting the layers in which they are printed to a flash exposure, uniform over the image area, with light to which those layers are predominantly sensitive, the flash exposure being given simultaneously with or after the printing exposure, the flashing light, according to the invention, reaches the material by way of a transparent reflector which composes into a single beam, flashing lights respectively for the two layers incident on the reflector from different directions. More than one multicolour print may be made and flashed in one operation by the use of optical dividing systems. The intensities of the flash exposures may be individually controlled during the printing, and, in the case of kinematograph films, may be changed automatically for different sections of the film as by means under the control of notches in the edge of the film. Apparatus is shown in Fig. 3 for printing by projection from a multicolour film N, e.g. a tricolour dye-imbibition record, simultaneously on to two similar multilayer sensitive films P1, P2. The record N is projected by a lighting system 31, 15 and objective 16 on to a dividing system 25, 26, the semi-transparent reflector 30 of which transmits one image beam 11 to the film P1, and reflects the other beam 12 via a laterally-inverting reflector 50 to the film P2. Simultaneously with the printing, the individual component images of the prints are given flash exposures from three light sources 32, 33, 34 which, assisted by two transmitting reflectors 20, 40, direct flashing beams 2, 3; 4 upon the transmitting reflector 30, which passes them on to the films P1, P2. The flash exposures are separately controlled by iris diaphragms 72, 73, 74, and blue, green and red filters 62, 63, 64. In a modified apparatus, three black and white component colour record negatives are projected, with the aid of coloured lights and a pair of reflectors similar to 20, 40, through an objective to form images in superimposition on a multilayer sensitive film, and the flash exposures are made simultaneously through the film support from a flashing system similar to that shown in Fig. 3. Provision may be made in this form also for printing and flashing two positives in one operation. The films P1, P2, may be processed in known manner as by reversal and colour development. The method may be applied to two-colour reproduction also. The colours of the original record may be natural or false so long as the colour sensitivities (which may include sensitivity to infra-red or ultra-violet) of the layers of the print material are co-ordinated therewith.
