Title: Electrical connector with paddle shaped tubular blades - has ring shaped strips separated by gap bridged by contact blades with curved sides (SW310576)
IPC: H01R13/187
Filed: 1975-01-20
Abstract: Electrical connector of the type with the paddle shaped conducting blades arranged in a tubular shape. The connector (10) is integrally stamped out of a sheet made from suitably electrically conducting material, e.g. byrillium copper. It has two strips (12, 14) separated by a gap with a number of separated bridging blades (16). Each blade has curved sides (18) which are convex in shape, so that the end connections of each blade has a smaller width than the strip. The blades are connected to the strips with spring loading and can rock slightly around the longitudinal axis. The strips are arranged in a circular configuration which produces the tube shape for the blades. The blades will be at an angle relative to the strips.

Title: High-rise automated warehouse - has assemblies of vertical compartment rows forming cages for lifting mechanism
Inventor: DIMITROV DIMITER ANGELOV
IPC: B65G1/04
Filed: 1975-04-22
Abstract: The warehouse is for the storage of palletised loads, and comprises assemblies each consisting of four vertical rows of compartments of rectangular section forming the cage of the independent assembly. Each assembly comprises two opposite vertical rows of single compartments, and two others of double compartments. Thus the common backbones of the rows form the cage of the assembly in which the lifting mechanism is situated. The set of compartments thus forms one or more horizontal rows of assemblies, supported on the sidewalls of the single-compartment rows, and the centres of the cages lie on a straight line.

Title: Garden plant supporting stake - has three sections with holes for ties or horizontal bars and stabilising washer bearing against wedge-shaped projections
IPC: A01G9/12
Filed: 1975-10-03
Abstract: The garden-stake (1) is in three sections. The top one has holes (2) in to enable the plant to be tied, or supported by a ladder of horizontal rungs inserted in them. The middle section has a stabilising-washer (7a) which can be moved up and down. The washer (7a) has two notches in it to enable the washer to slide between downward-pointing catches (8) on the section. By turning the washer (7a) it can be fixed underneath any catch (8) at a level above the pointed-ended bottom section (6) depending on the hardness of the ground and the size of the plant being supported. The sections are fixed together by stop-pieces in the bottom end inserted into cavities in the top end of the adjacent section. The cavities in the top ends have skewed portions at the bottom for interlocking the sections.

Title: Nail gun for use in building construction - has spring loaded trigger operated nail firing mechanism with discharge orifice removing lower nail body
Inventor: PRIOU STEPHANE
IPC: F16B19/14
Filed: 1975-11-17
Abstract: The device is for attaching a projectile to a wall which has been fired at the wall from a distance, such as a construction nail which is to be embedded in a concrete block. It comprises a container with an orifice through which the projectile head is passed. A spring loaded trigger mechanism protrudes from the container on the same side as the orifice. When the trigger is activated against the tension of its return spring, it dislodges a spring mounted firing plunger which is propelled towards the projectile base. The resultant explosion fires the projectile through the discharge orifice and into the wall, the orifice diameter permitting the passage of the head but severing the lower larger diameter body section.

Title: Nail for assembling panels to studding - has cruciform section point to pierce panel and threads to grip stud
IPC: F16B19/00
Filed: 1975-12-10
Abstract: The nail is for assembling thin sheets to the ends of posts or studding. It consists of a large, slightly domed head (9) connected via a plain shank (10) to a grooved or threaded portion (11) extending to a long sharp point (20). The underside of the head has shallow ribs (22) which are arranged in a cruciform configuration. The point (20) is also cruciform in section, and the positions of its ribs correspond to those under the head. A sharp blow with a hammer serves to drive the nail through the sheet which is to be attached to the stud. The length of the plain portion of the nail is the same as the thickness of the sheet and the stud is pre-drilled to a diameter slightly less than the threaded part of the nail.

Title: Thermostatic controller probe with differential expansion element - has oil and wax filling as damping against rapid fluctuations
IPC: G12B1/00
Filed: 1976-03-04
Abstract: The thermostatic controler probe consists of a hollow cylindrical tube filled with an oil such as toluence. An inner chamber of elastic material contains a wax filling with a different coefficient of expansion. The action of heat on the probe causes a pressure build-up in the capillary tube linking it to an actuator and forces the piston further out of the cylinder to operate a valve or other device. The capillary tube is also connected to a regulator device which has an inner piston to which is screwed an adjuster knob to alter the pressure in the system and hence the operating range of the actuator.

Title: Dipping machine for raised dough cakes - with distribution, dipping, draining, decorating and packing modules
IPC: A21C15/00
Filed: 1976-10-11
Abstract: Dipping of cakes of raised dough, for making a type of rum Baba, is effected in a machine which very largely reduces the amt. of human intervention needed. Each operation has its own module. The frame, made in one piece, supports the vertical or inclined racks which guide the cakes. A regulator for removing the cakes from the rack to the conveyor belt, of the rod type, slides backwards and forwards on the runners under the influence of the rack (b) and pinion; this drives the conveyor via the chain when actuated by the hydraulic jack. Elimination of hand dipping saves costs and leads to a more regular finished prod. All the other processes are programmed to synchronise with this operation.

Title: Rod with polyvinyl chloride sleeve forming anchorage in rocky ground - is protection against corrosion and localised stresses
IPC: F16B13/14
Filed: 1976-10-18
Abstract: Anchorages are formed by (a) drilling a hole in rocky ground, (b) inserting an anchorage rod, and (c) filling the remaining space wholly or partly with concrete. Specifically the anchorage rod is sheathed in a tight-fitting sleeve of PVC. When the concrete filling is only partial, the sleeve would protect the bare metal not covered by concrete from corrosive attack, when the filling is complete, the rod can move within the PVC sleeve and so adapt itself to any localised stressed that may act on it.

Title: Torque-free connection between two shafts - has hollow in one shaft holding moulded mating part captive
IPC: F16C33/14
Filed: 1976-12-03
Abstract: The end of one shaft (2) has a cylindrical hollow space (4) which is near the end of the shaft. A bore in the end face of the shaft connects to the hollow space. The diameter of the bore in the end face is smaller than the diameter of the hollow space. The mating part (6) which connects the second shaft to the first one is made from plastic and is moulded on to the other shaft. The moulding extends into the hollow in the end of the first shaft. When the plastic extension cools after moulding, it will shrink and sit with play in the hollow end, where it is held captive. This enables the two shafts to rotate relative to one another while taking up axial force.
