Title: Curtain rail support bracket - has removable leg to simplify insertion of rail, locked with wedging action by screw
IPC: A47H1/144
Filed: 1975-02-13
Abstract: The curtain rail support bracket holds a pair of rails (5), each in the shape of an inverted U with rolled-over edges. It has a horizontal arm (6) with a pair of correspondingly inverted U-shaped extensions (3) suspended from it, to receive the rails. The inward facing vertical leg (4) of each U- shaped holding member (3) is removable, to assist assembly. When inserted, a wedge shaped portion (10) on top of the leg fits into a triangular recess formed by a bent arm (8, 9) on the underside of the horizontal arm (6). The wedge portion is then locked inside the recess by a screw (12) passing through the horizontal part (9) of the bent arm. The shape of this recess causes the removable leg to be forced upwards and also inwards against the curtain rail (5), to lock it.

Title: Assembly and welding transfer jigs and tracks - contg. piece of brittle plastic which fractures under accidental shock loads
IPC: B25H1/00
Filed: 1975-02-26
Abstract: Improvements to jigs and tracks for the location and transfer of components being assembled and welded. The novelty is that each support for the components consists of strong rigid elements which are sepd. by a spacer made of a non-deformable brittle material which is designed to break under accidental conditions of shock before any deformation of the supporting structure occurs. The spacer is pref. made of a phenol-formaldehyde resin plate with a cross-section which fractures at a known load. It is esp. a plate of standard size which can easily be inserted in vulnerable zones of jigs and tracks on supporting structures. Device is esp. for the assembly of sheet metal or bodywork on prodn. lines used for mfg. motor cars. Transfer tracks etc. are often subject to accidental shock which distorts the track so the smooth flow of components is prevented. The spacer is designed to break before any damage or distortion is caused to the rigid parts of jigs, conveyors etc.

Title: Shield for driving tunnels into unstable rock strata - has vertically pivoting spring loaded platforms for cut rock attached to horizontal knives
Inventor: SEMENOV A N
IPC: E21D9/06
Filed: 1975-03-20
Abstract: Shield for driving tunnels in loose and unstable rock strata includes a knife ring with vertically and horizontally projecting knives for breaking the rock and with horizontal platforms positioned against the horizontal knives. The platforms are so mounted that they change their position in a vertical plane to assume a position in which accumulated rock is removed from their surface. Each platform (7) is so preloaded by a spring force that when loaded with the cut rock it tips downwards in a vertical plane. With a certain weight of rock removed from the platform during the tipping movement the platform is returned by the spring force in its original horizontal position. The platform (7) is preloaded by leaf spring (14) attached at one end to the horizontal knife (5) to pivot in vertical plane and carrying a roller (15) at its other free end which is in contact with the platform (7) during its tipping movement. The middle part of the leaf spring is supported by a rod attached to the horizontal knife which limits the spring movement in the vertical plane.

Title: Photomigration process for colour copying - using thermal and/or solvent vapour development, for simplicity and self-fixing
Inventor: KISHIMOTO SHINZO
IPC: G03G15/05
Filed: 1975-07-15
Abstract: A colour copying process comprises (a) simultaneous electrical charging and selective exposure of a recording material, consisting of a substrate with a colour developing coating and then an electrical insulating coating, which can be softened by heat and/or solvent vapour and contains photoconducting particles at least near the free surface, which contain a component that can react thermally with the colour developing coating; and (b) softening the electrical insulating coating by the action of heat and/or solvent vapour, so that part of the photoconducting particles migrate selectively through the softened layer and come into contact with the colour developing layer, where they react, with colour formation. Specif., the colour-forming components consist of an electron donor and acceptor, pref. a leuco dye and a cpd. with a phenolic OH gp. The colour developing coating can also contain a synthetic resin binder. The process is simple and self-fixing and gives copies with high density and high contrast.

Title: Travelling formwork for concrete walls - has vertical stanchions supporting travelling platform with suspended shuttering and hydraulic jacks
IPC: E04G11/28
Filed: 1975-07-18
Abstract: The travelling formwork for the construction of concrete walls has two vertical stanchions (2), which are braced by common cross beams. The stanchions provide a guide for a travelling platform (10) which supports formwork shuttering panels (13) underneath. The concrete wall (7) is cast between the formwork. When the concrete has set, a hydraulic ram (35) jacks the table further up the stanchions. The wall is cast with periodic holes (22) which align with holes in the shuttering and are used to clamp the forwork when another pour is made. The stanchions have feet which rest on the ground during the initial stages of construction of the wall.

Title: Automatic valve for filling tank - has float to operate valve element released by head contacting levers
IPC: F16K31/26
Filed: 1975-11-12
Abstract: The valve permits automatic regulation of the contents of a tank. It comprises a valve seat (12, 14) positioned vertically above a seating (10) and kept open by pivoted levers (26, 28) latching in a groove (34, 36). A vertical rod (42) is positioned between the levers, its lower end connected to a float. As the tank fills the float and rod move upwards until an enlarged head (44) contacts the levers. These spread outwards, releasing the valve seat which drops to give an immediate shut-off. A handle (48) has similar curved levers (52) latching under (56, 58) the valve seat. These can lift it to permit manual filling above the preset level.

Title: Boat hull of GRP and foam core sandwich - made by winding round mould and sectioning for removal
IPC: B32B5/24
Filed: 1975-11-24
Abstract: Boat hull or other hollow article e.g. pipe or container, of sandwich wall construction, is made or an internal mould by winding layers of lay-up matl. completely round the mould. An inner layer of resin impregnated fibre is followed by a core layer of synthetic foam matl. and an outer layer of resin impregnated fibre to complete the sandwich. The moulded article is cut into two sections for removal from the mould which has a release coating. The numerous draw-backs in boat construction of laying up on a plug type mould are avoided and building simplified. The present invention enables tension to be applied so that no distortion occurs. Fasteners are not needed. Quick cure resin can be used without styrene release from the resin onto the core. There is not waste of matl. The mould is immediately re-usable.

Title: Food mincing machine - has perforated discs and cutters with forced displacement element between compartments
IPC: B02C18/30
Filed: 1976-06-04
Abstract: A mincing machine for meat and other food is equipped with material feeding elements which pass the material through perforated discharge elements. Rotating cutter blades cooperate with the perforated discharge elements and an additional forced circulation element provides a positive displacement of the material. This prevents clogging of the perforations by tendons which leads to a stoppage of the material feed and its undue temp. rise.
