Title: Stop for hollow lathe shaft - has alternate rubber and steel rings compressed to expand radially and lock inside
IPC: B23Q16/00
Filed: 1975-07-17
Abstract: An adjustable stop inside a lather shaft, has alternate steel and rubber rings mounted on a core tube (1). An axial contraction of the composite ring liner causes the round section rubber rings (2) to expand radially, thus locking the stop in the desired position in the shaft. A stepped end disc (8, 9) and stepped sleeve (4, 5) may be at each end to obtain axial 'float' (e). The stop is contracted and expanded by a screw jack, using a threaded bolt (10) through it, with its head bearing on one stop end disc (8) and its other end engaging a tapped block (11) which bears on the opposite end disc (9).

Title: Panelled folding bed settee - has Z-frame with legs and base table support
IPC: A47C17/23
Filed: 1975-10-03
Abstract: The bed-settee has a hingeing metal support frame and is divided into three longitudinal frame panels (7,15,20).

Title: Angular protector for measuring slopes - contains fluid damped rotating pendulum with pointer to locate vertical axis
IPC: G01C9/12
Filed: 1975-10-20
Abstract: The protractor is used in mechanical construction and building operations to check or establish slopes. Problems of using bubble levels are overcome by use of a fluid-damped pendulum to provide a vertical axis. The protractor (1) comprises a rectangular body with two plane and parallel sides (2,3). A pendulum (6) is mounted to rotate freely around a transverse axis (7) within a transparent sealed enclosure (8). A window (12) with lateral boundaries (10) carries a scale (14) graduated in angular degrees, against which a pointer (15) on the pendulum rotates. A float (19) makes the density less than that of the damping fluid within the enclosure, and also places the centre of gravity away from the axis.

Title: Pocket knife with automatic blade - has master slide operated by external catch to spring load blade for opening or closing
Inventor: CHAUVET JEAN
IPC: B26B1/08
Filed: 1976-05-26
Abstract: The pocket knife has an enclosed blade, opened and closed automatically by an external catch. When this catch is moved to open the blade, a master slide (15) tensions a coil spring (20). A trigger (13) is released, its head entering a recess. The end of this recess moves opposite the head of a second trigger (12). This pivots over a stop (9) to release the blade (6), projected outwards by the spring. To close, the catch is moved in the opposite direction. The master slide returns and retensions the spring, releasing the second trigger (12) to enter the recess. The cycle repeats to return the blade.

Title: Surgical knife with laser beam coagulator - has laser beam of intensity just adequate for coagulation transmitted through transparent cutting blade avoiding charring of tissue
IPC: B23K26/06
Filed: 1976-10-11
Abstract: When a laser beam is used as both cutter and coagulator, there is a tendency to cut too deep, and to char the tissue instead of merely coagulating. Using the appts. the cut is made with a conventional instrument, and a laser beam of lower intensity (sufficient for the coagulation only) is directed just behind the cutting edge. The cutter is preferably of a material transparent to the laser beam used, and having a high refractive index at that wavelength. Total internal reflection then limits the laser beam to the interior of the cutter material until it reaches the vicinity of the cutting edge (see illustration). The material used is preferably sapphire or germanium.

Title: Overhead conveyor current carrying rail - has sunken regions between resilient flanges forming pockets, allowing conductors to protrude
IPC: B60M1/30
Filed: 1977-01-10
Abstract: The current carrying rail particularly for an overhead conveyor has an outside section with a zone for electric contact (14). The section (10) has a 'U' form with two similar flanks on a base. The external surface of the base serves as a contact zone and the internal opposite side is semicircular. The outside surfaces of the flanks are at least partly flat from the base and have at outer extremities a 10 deg. chamfer. Elements clip into an insulator support with a flat base with pairs of ribs (54, 55) inclined towards one another at an angle slightly more than that of the 'U' flanks. Each pair of shoulders can clamp the rail at its flanks. The ribs can partly enclose the rail element to limit the access to the zone of electrical contact.

Title: High power, high speed electromagnet motor - has eccentric soft iron cores moving in series of hyper-cycloids
IPC: H02K25/00
Filed: 1977-02-09
Abstract: An electro-magnet-based motor is capable of very high rotation speeds and power. The motor casing has a large number of cores and pole pieces equally distributed around its perimeter the solenoids of which are controlled from a distributor driven from a motor reversing the supply polarity at each half rotation. The cores may be switched using orthodox hydraulically operated mechanical circuits for magnetic shunting driven from a motor and distributor. The central mass fits very closely within the pole pieces and has eccentrically positioned soft iron elements moving in shallow amplitude hypercycloids. Transmission of power is via a cogged wheel driven from a crank from the central mass.

Title: Cellulose breaking-down equipment - has particle-free fluid flow to prevent blockages and reduce maintenance
IPC: D21C3/00
Filed: 1977-02-16
Abstract: Appts. is to break down cellulose material. The cross section of the outlet of the impregnating vessel is from one-quarter to one-third of the cross section of the processing vessel. The inlet for the breaking-down fluid, which carries the cellulose chips in a column at a relatively higher temp., has its exit opening positioned at a gap below the outlet of the impregnating vessel. This gap is equal to or greater than half the diameter of the processing vessel. An equal dispersion of the breaking-down fluid is passed through the chips column without a short circuit in the flow pattern, to the outlet at the upper end of the processing vessel. The fluid flow passes out of the outlet free of chips from the vessel without requiring filtering. The design prevents blockages as there is no clogging effect from the material, so that the equipment requires less maintenance and cleaning.

Title: Power drive for tipping bulk goods onto trailer - has line successively emptied and uncoupled by hydraulic ram carried on tractor vehicle
IPC: B60P1/16
Filed: 1977-03-10
Abstract: The power equipment for operating is carried on the tractor only. The trailers carry hoppers which tilt to empty backwards. They carry a locking mechanism and a system for uncoupling the bogie and also coupling it up again. The tractor carries a telescopic ram (11). The ram swings on a horizontal axis near a nose on the trailer immediately behind the tractor. There is also a mechanism on the tractor to hold the chassis of the adjacent trailer. The ram is connected through so that it can tilt the rear hopper to empty it, by claws. The hydraulic power used to actuate the ram is also used to uncouple the last trailer so that the hopper on the next one can be tilted and emptied.

Title: Yarn double twister has stop motion
IPC: B65H63/028
Filed: 1977-05-12
Abstract: Twisting device for twisting together two rovings to form a twisted yarn includes e.g. a pair of feed rollers which advance the rovings and ring and traveller twister. - Pref. between the feed rolls and twister the rovings pass through a breaker device, which guides the rovings along a predetermined path. If one roving breaks its absence automatically causes a change in path of the second roving, so that the second roving acts on a cutter element and itself is broken. - The device can be automatically shut down when one roving breaks so that long lengths of miss-formed yarn are not produced.
