Title: Electric switch
Inventor: SHINOMIYA SHIGEKI
IPC: H01H13/30
Filed: 1982-10-25
Abstract: A switch comprises a drive element 6 inserted in a through hole 1d of an operating member 1 and placed so as to execute a rocking motion on a frame 3. When the operating component 1 is operated, the drive element 6 is caused to slide on a movable contact plate 14 to swing the moving contacts, such that the contacts are switched. The distance A between the edges of the lower opening of said through hole 1d with which said drive element 6 comes into contact, in the direction in which said drive element slides, is selected to be greater by a predetermined amount S than the width of said drive element B, so that when said drive element is brought into contact with one edge of said opening, a gap of a predetermined distance is formed between the drive element and the other edge of said opening. Contact chatter is thereby avoided since a rapid snap-over is achieved. <IMAGE>

Patent GB-2139281-A (GB)
Title: A lock having a safety turning knob
Inventor: BENGTSSON SIGURD WALTER
IPC: E05B65/10
Filed: 1983-11-18
Abstract: In order to normally permit the unlocking of the door from its inside by means of a knob, while occasionally making an un-authorized opening impossible, the knob (19) is mounted upon a driver (20), which may be axially displaced into and out of engagement, respectively, with a rotatable member (14) in the lock. When the driver is retracted from the rotatable member, a radially directed peg (25) will be introduced into a groove (26) in a washer (24), in which the driver is journalled, which prevents rotation of the driver and the knob. The driver is provided with peripheral grooves (21, 22), which in co-operation with a spring loaded ball (23) form end portion stops for the driver. One (22) of these grooves is deeper than the other, and defines a breaking indication. An un-authorized activity at the knob will destroy the driver, but leaves the lock unharmed.
Patent GB-2143750-A (GB)
Title: Spraying device separating liquids
Inventor: LEWIS QUENTIN JOHN
IPC: B05B3/08
Filed: 1984-07-19
Abstract: The device comprises a rotatable cone (12) whose apex extends into a liquid so that, on rotation, the liquid rises up the cone and is ejected radially in a spray. A shield (11) encloses the cone and has a slot (16) controlling the spray width and a flange (18) limits the axial extent of the liquid on the cone. The same principle is usable to separate immiscible liquids, since different liquids may be ejected from the cone at different axial locations. <IMAGE>

Title: Volume compensation in hydraulic rotary-vane dampers
Inventor: ZIRK WOLFGANG
IPC: B62D55/108
Filed: 1984-08-31
Abstract: In order to compensate for increase in volume of working liquid with temperature, the working chambers 18, 19 of a rotary-vane-type damper are connected to a reservoir (30,31) via compensating valves 26, 27. On clockwise movement of the rotor vanes 14, the pressure in pressure chamber 18 ensures that compensating valve 27 is closed and therefore (via link 28) valve 26 is open. Liquid can therefore flow from the suction chamber 19 to the reservoir. On anti-clockwise movement of the rotor vanes 14, liquid can flow to the reservoir from chamber 18 (which is now not under pressure). Flow from the reservoir to the working chambers (on fall in temperature) in effected by feed pump (Figs. 3,5) driven by the pressure from the working chambers. This flow bypasses the valves 26,27. The rotor vanes contain the usual damping valves. <IMAGE>

Title: Carton
Inventor: MEAKINS STANLEY ROY
IPC: B65D19/20
Filed: 1984-09-01
Abstract: A carton formed from folded stiff sheet material has a tray-like base 21 having upstanding peripheral walls 2, 3 into which a foldable tubular wall- defining member 11, 12 can be inserted and locked thereto by inter- engageable edges 5, 6, 17 on the lower ends of the walls of the wall- defining member 11, 12 and the peripheral walls of the base 21. Each of a pair of opposite end walls 12 of the wall-defining member has an upright central crease 16 therein which permits the end walls 12 of the wall-defining member to be folded inwardly to effect corresponding closing together of the side walls 11 of the member, thereby to flatten the wall-defining member. Fold lines 9 facilitate folding down of the walls 2, 3 of the base 21 to a flattened condition. <IMAGE>
Patent GB-2147378-A (GB)
Title: Braking pressure control unit
Inventor: ZUTT ULRICH
IPC: B60T8/28
Filed: 1984-09-14
Abstract: A braking pressure control unit is of the kind in which the stepped pistons (14, 15) of the or each proportioning control valves (8, 9) has an effective surface (A1) exposed to the pressure of a control chamber (60, 61) which communicates with the inlet (4) of a brake circuit via a valve seat (32) engageable by an inertia element (33). The control chamber pressure acts on the effective surface (A1) in the control valve closing direction. The inertia element (33) is moved away from its associated valve seat (32) by a sufficient vehicle deceleration. One of the stepped pistons carries an extension (40) forming a stop (41) for the inertia element (33) so that, in the initial unpressurised state, the connection between the control chambers (60, 61) and the inlet (4) is held open, but is closed by the inertia element (33) as the stepped piston is displaced by increasing input pressure before closing of the control valve (8) and is opened again at the set deceleration. Depending on the pressurisation of the effective surface (A1) there will result an increased change-over pressure and a changed reduction ratio for the loaded vehicle and upon failure of the brake circuit. In Fig. 2 (not shown) the inertia value axis is perpendicular to the central valve axes. <IMAGE>
