Title: Pressure tight screwed closure - has two interengaged caps to prevent access for young children
IPC: B65D50/04
Filed: 1977-01-03
Abstract: An inner screwed cap (3) has upstanding lugs (11) which engage between corresponding lugs depending from inside the top of an outer cap. The outer cap is retained on the inner cap by an internal shoulder which engages under the lower edge of the inner cap. The opposed lugs have vertical faces which engage when the outer cap is rotated to screw the inner cap on to the neck of a receptacle. The faces which engage when the outer cap is turned in the opposite direction are inclined so the outer cap lifts on the inner cap so the latter is not unscrewed. Axial pressure has to be exerted on the outer cap to unscrew the inner cap.

Patent FR-2348519-A1 (FR)
IPC: G04C9/04
Filed: 1977-04-14
Abstract: In an analogue electronic timepiece comprising a minute hand mounted on a cannon pinion, an hour hand mounted on an hour wheel, a motor driven by pulses produced by an electronic circuit and a gear train connecting the motor pinion with the cannon pinion and hour wheel, means for setting the minute hand and hour hand to amend the time displayed by the timepiece comprises a setting wheel which is rotatable by a crown wheel in one direction for moving the hands clockwise and in the opposite direction for moving the hands counterclockwise. The setting wheel is coupled to the gear train by a friction pinion at a point in the train which is approximately midway between the motor pinion and the cannon pinion and hour wheel so that the blacklash generated in moving the hands clockwise in a setting operation is approximately equal to the backlash generated in moving the hands counterclockwise. The electronic circuit includes means for generating pulses at the conclusion of a setting operation so as to compensate for the blacklash in the gear train. Since the backlash is approximately the same regardless of the direction the hands are moved in the setting operation substantially complete compensation for the backlash can be attained regardless of the direction in which the hands are moved.

Title: Concrete reinforcing wire bending machine - has wire held by fixed and sliding vices with piston slide related to latter
IPC: B21F1/04
Filed: 1977-06-14
Abstract: The machine which bends straight wire (8) into a continuous uniform undulating 'V' formation, may treat reinforcement for concrete.

Title: Multilayer circuit board with integral flexible appendages - uses array of flexible circuit layers bonded between rigid layers having suitable electrical connections
Inventor: TAYLOR GLEN JAMES
IPC: H05K3/00
Filed: 1977-06-21
Abstract: All the layers are substantially larger than the size the finished circuit board is to be and selectively bonded and slotted in pre-selected locations, and maintained in this over-sized condition throughout the procedure in which holes for interconnections are drilled, and plated through with conductive material. Only after the plating procedure has been completed are the portions of the upper and lower rigid layers removed from locations above and below the appendage portions, thus allowing them to attain the desired, flexible condition. By keeping the rigid layers intact, the assemblage is maintained rigid during the plating, thereby avoiding work hardening of the flexible portions even without tools for restraining the flexible portions.

Title: Dredger with submersible pivoting boom - has demountable sectional form with ballast compartments to provide boom buoyancy
IPC: E02F3/90
Filed: 1977-06-23
Abstract: The dredger is suitable for the maintenance of relatively deep navigable channels. It utilises a sectioned pivoting submersible boom. The section size is dictated by overland transit gauges. The sections incorporate ballast chambers to give the boom bouyancy. This reduces overturning moments on the support vessel. The vessel and the boom both have a long legged 'U' shape in plan. The former has a crane by which the boom is manipulated, and the latter a breaker tool with a pipe by which dredged material is sucked to the surface. The pipe has a suction inlet with a discharge outlet. A motor pump is used to provide suction. Winches and cables are used to pilot the vessel, with pneumatics to control the quantity of water in the ballast compartments.
