Title: Improvements in vehicle headlamps
IPC: E04C2/54
Filed: 1965-05-24
Abstract: 1,103,631. Vehicle headlamps. S. IMAI. 24 May, 1965 [25 May, 1964 (2)], No. 21860/65. Heading F4R. In a vehicle headlamp the lens or front glass comprises two portions 40<SP>1</SP> and 40, the portion 40<SP>1</SP> including a pair of interengaging prismatic plates with one face 35<SP>1</SP> of each prism being opaque so that light transmitted through the portion 40<SP>1</SP> is directed below the horizontal and light transmitted through the portion 40 is directed in a direction different from that directed by the portion 40<SP>1</SP>. Each portion 40<SP>1</SP>, 40 may be associated with its respective light source 38, 381, the sources being operated individually and separated by an opaque plate 39 with upper and lower reflective surfaces. As shown, the portion 40 is similar to the portion 40<SP>1</SP> but reversed relatively thereto so as to direct light upwards and the light source 381, which is weaker than light source 38, may be switched off on meeting oncoming vehicles to eliminate glare to the oncoming driver. The lens may be covered by a transparent protective plate 40<SP>11</SP>. In modifications, the upper portion 40 may comprise arcuate or V-shaped arrangements of prisms, a transparent or frosted portion or a small convex lens, or the prisms may be arranged vertically with the two portions on opposite sides of a central line and the prisms on the two sides relatively reversed. The lens portions may be coloured differently or be covered by light filters, e.g. red on one side and green on the other.

Title: Locks
IPC: E05B29/00
Filed: 1966-05-21
Abstract: 1,134,046. Locks. J. F. WELLEKENS. 21 May, 1966, No. 22736/66. Heading E2A. A lock comprises a cylindrical casing 1 and a plug 9 rotatable therein and provided with a series of wafer type tumblers 26 slidable within a depression in a series of abutments 30 which are rotatable to other positions to enable the shape of the key to be changed. Each abutment has a central aperture for the plug and a central depression with internal shoulders 43-46 of various heights and a corresponding number of external peripheral notches 37 to 39 which selectively engage a rib 34 on the casing. The plug together with the tumblers and abutments is slidable axially from the casing, to change the angular setting of the abutments to use the lock with a different key, after removing a C shaped ring which engages a groove in an end disc rotatable with a plug which is connected by a stud to the bolt. An end abutment has a central aperture for the plug. one peripheral notch, an internal recess and a groove whereby when the key is inserted in the key slot 24, a lug 28 on the tumbler plug. To prevent picking the lock, a channel engages the groove and limits rotation of the shaped metallic lining strip 65 with longitudinal ribs 66 is inserted into the key slot to limit the space for the insertion of a pick. If a pick is inserted and lifts the end tumbler, a lug on the tumbler enters the internal recess on the end abutment and prevents rotation of the plug the amount requisite to bring the lugs 28 of all the tumblers into contact with a shoulder on the corresponding abutments before inserting the pick to lift the tumblers 26.

Title: Rotary pumps and engines
IPC: F01C1/20
Filed: 1957-07-18
Abstract: 837,128. Rotary pumps and engines. MARSHALL, J. W. July 17, 1958 [July 18, 1957; April 17, 1958], Nos. 22770/57 and 12211/58. Class 110 (2). In a rotary pump or engine of the rotary abutment type one member 9 is in the form of an eccentric and co-operates with a two-lobed member 8, gearing 6, 7 constrains the member 9 to rotate with twice the angular velocity of the member 8. A rotary valve 26 may permit of expansion or compression of the fluid medium. The compression ratio may be altered by adjusting the edge 19 of the port 17, and by the introduction of a valve 25 the mechanism can be used at will as a blower without compression. Discs mounted on the rotor shafts may provide sealing means and may also be so constructed as to balance the eccentric rotor 9. The rotor tips may be flattened to decrease leakage flow across them and may be provided with labyrinth or other type packing. A number of casings 1 may be arranged side by side for multistage compression, with intercooling, the rotors being offset angularly for balancing purposes.

Abstract: 638,035. Moulding parts of sliding-clasp fasteners. UNITED STATES RUBBER CO. Aug. 18, 1947, No. 22892. Convention date, Oct. 24, 1946. [Class 87 (ii)] [Also in Group XXV] The interlocking elements of a water-tight sliding clasp fastener are provided with recesses through which extends a strip of rubber bonded to the tape between the elements, the edges of the rubber strip being adapted to contact each other and form a fluid-proof seal. The fastener elements shown in Figs. 1 and 16 have a pair of projections 25 and coacting recesses. The fluidproof material 16 is applied to the tapes in a mould, Fig. 16, the elements 11 being engaged with dummy mould elements 48 which may also be mounted on a tape 49. The mould elements carry projections 57 to form the contact edge 19 of the strip in the recesses 18 in the fastener elements. Other parts of the mould elements prevent entry of the rubber into the recesses of the elements 11. The lower cover 50 is applied first and the rubber material is injected into the cavities through the channel formed by the recesses 18 until the mould is filled. The top cover 52 of the mould is then applied and the mould covers pressed together.

Class 98(2) The process of Specification 708,151 in which diapositives and kinematograph films with continuous tone gradation as well as ordinary diazo copies are made by selectively exposing a "diazo film layer" containing a p-aminobenzene diazo compound which yields an active photochemical decomposition product, as described in that Specification, rendering the copy alkaline and then developing with an aqueous solution of a coupling compound; is modified by (1) employing, additionally, in the " diazo film layer " a diazo compound which yields a less active or inactive photochemical decomposition product, and (2) adding part of the coupler during the intermediate step of rendering the copy alkaline. For (1) Example 1 specifies the zinc chloride double salt of p-diazo-o-chloro-diethylaniline or the corresponding m-chloro compound as additional diazo compound, and for (2) Example 2 specifies phloroglueinol as coupler, part of which is added during the intermediate step. Softer gradation results from both of these modifications.

Title: Improvements in and relating to refrigerators
IPC: F25D11/02
Filed: 1947-08-21
Abstract: 638,675. Refrigerating. BRITISH THOMSON-HOUSTON CO., Ltd. Aug. 21, 1947, No. 23229. Convention date, Aug. 23, 1946. [Class 29] [Also in Group XXIX] In a refrigerator having a primary evaporator 12 cooling a freezing chamber 3 and a closed secondary evaporating-condensing system 16, 17 cooling a food chamber 2 at a higher temperature, a control device 21 is provided for selectively directing condensate from the condensing portion 16 of the secondary system either to a condensate reservoir 22 or to the secondary evaporator 17. The secondary condenser 16 is clamped to the primary evaporator and connected by a pipe 23 to the upper part of a valve chamber 21 from the lower part of which extend pipes 25, 24 leading to the condensate reservoir 22 and the secondary evaporator 17 respectively. A vane or deflecting member 29 of magnetic material freely pivoted at 30 within the valve chamber is operated by a permanent magnet 31 mounted on an arm 32 on a shaft in line with the pivot 30 and connected by a rod 33 with a bellows 27 actuated by a thermostatic bulb 28 in the food chamber 2. When the temperature of the food chamber reaches a predetermined low value the vane 29 is moved to direct condensate into the reservoior 22, which is connected by a pipe 37 to the vapour return pipe 26 of the secondary system. On rise of temperature condensate is directed to the evaporator 17. To eliminate frequent oscillation of the vane 29 a small amount of refrigerant is continuously supplied to the evaporator 17 from the reservoir by a capillary tube 36. A barrier 35 prevents passage of refrigerant from one side of the valve chamber to the other. For defrosting the secondary evaporator a modification is described in which the permanent magnet 31 is replaced by an electromagnet which is de-energized by a time switch for defrosting so that the vane 29 falls by gravity to a position in which the pipe 23 is to the left of the vane so that all the condensate is directed to the reservoir. Simultaneously a heating circuit is completed to heat the capillary tube 36 to stop the flow of condensate through this pipe to the evaporator.
