Title: Power cable junction sleeve has split tubular housing - whose inner-and outer-surface axes are displaced vertically to reduce material
IPC: H02G15/113
Filed: 1974-02-08
Abstract: The junction sleeve, for power cables of 1 to 10 kV, consists of an insulating tube split along its length into two halves (2, 3). The axis (9) of the circular inner surface of the tube lies below the outer surface axis (8) so that the wall-thickness at the top of the sleeve is much greater than at the bottom where the halves interlock. The ends of the sleeve are tapered down with lead collars (4) to the cable diameter. The displaced axes reduce the amount of material needed to make the junction sleeve, reduce the amount of epoxy resin needed to fill it and reduce the overall weight. (The reduction in size is between 15% and 30%).

Title: Locking mechanism for sliding screens - sliding lever-actuated hooked bolt rotates in vertical plane to engage pin
IPC: E05C19/14
Filed: 1974-02-14
Abstract: Locking mechanism for use esp. on abutting edges of sliding screens, is economic, simple and compact, and obviates accidental unlocking, and constitute a horizontal sliding hooked (19) bolt (18) locating on one leaf (4) edge (5) and engaging a projecting pin (6, 7) on the opposed leaf (3) edge, the bolt sliding in a leaf edge mounted runner piece (16) and being mobilised via lever (21) hinging (22) to the runner frame (16) and connecting via tie rod (23) to the bolt tail. A universal joint type connection between the tie rod (23) and the bolt (18) tail allows the bolt to rotate in the vertical plane to engage the catch pin (6) on the opposing leaf. Thus by bringing the bolt to the end of its run, engaging the pin and rotating the lever back to abuts the runner the leaves are drawn and locked together.

Abstract: The information stored on a selected card can be displayed on a fixed video screen by using a reproduction head for scanning a selected recording track on the card, and supplying the video signals representing the stored information to the screen, for display of the latter. The positioning of the reproduction head, relative to the recording tracks carried by the card, is controlled via a manual selector, with the card and/or the reproduction head then being proved to allow scanning of the selected track. The initial pre-positioning of the recording head may be effected by using a counter supplied with a number of pulses from the manual selector and controlling the transverse movement of the reproduction head.

Title: Selector presenting individual fruits without bruising - for cutting prior to removal of stones
IPC: A23N3/00
Filed: 1974-04-10
Abstract: The vertically reciprocating shaft, of a selector to present individual fruits etc. from among a supply, e.g. in a shallow hopper, (which may be fed by a conveyor belt) is surrounded by a flexible sheet of cloth or rubber, between its top edge and a fixed support. The sheet is unstretched flat, and forms a right-conical surface when shaft is raised which inverts at bottom of stroke. Thus the shaft does not traverse pile of fruit, which is gently displaced as shaft moves up and down, so that bruising and crushing is obviated.

Title: Bowl shaped overhead radiant heater - has refractory lined upper shell clamped onto stainless steel lower shell
IPC: F24C15/22
Filed: 1974-04-12
Abstract: An overhead radiant heater consists of two shells, an upper conical shell (1) with a collar (8) at the top, and with a refractory lining (7) inside, and a lower, shallow dished shell (2) with corrugations (9) around it, acting as the emission surface and made of a stainless steel alloy containing (15%) carbon, (20%) chrome, (11%) nickel, (2%) silicon, and able to withstand (900 deg.C).

The upper and lowr shells are secured together by a clamping ring (3) around their edges, with an asbestos joint (6) between.
Patent FR-2282081-A1 (FR)
Title: Mixed yarns for woven reinforcement for rubber hose - to enhance the flexibility of hose e.g. for vehicle air conditioning
IPC: F16L11/115
Filed: 1974-08-14
Abstract: Woven reinforcement of rubber hose where the reinforcement comprise two coaxial helically wound weft yarns interlaced with an annular array of warp yarns, where one of the two weft yarns is an extensible elastic matl. with a lower coefft. of friction in contact with the warp yarns than the matl. of which the other weft yarn is made. The reinforcement is used in hoses required to bend through tight radii of curvature without collapsing, e.g., for automobile air conditioning hoses. After lay-up and release, the elastic weft yarns tend to contract and form a series of windings of smaller dia. than the turns of the non extensible matl. The hose structure is more flexible because the two sets of windings do not lie in the same circumferential plane.

Title: Pruner for fruit trees - has operating levers opening blade through cable and against spring
IPC: A01G3/025
Filed: 1974-10-22
Abstract: The tool has a small rounded arm (2) forming the blade stop. The cutting blade (3) pivots freely around its fixed pin (4). An energy storing spring (7) is fixed to the blade and lower end of the sleeve (10) which takes the shaft. The operating cable is also fixed to the blade and passes through a pulley on the end of arm (13). It is then attached to a runner travelling inside control lever. When the operator moves the handle down, the blade opens against the spring and the runner travels to the end of layer (17). When the handle is moved upwards after the horizontal position has been reached, the roller then moves quickly to the other end of the handle and the blade snaps shut under the influence of spring (7), cutting the branch with very little effort on the part of the operator.

Title: Reinforcement for ski fastenings - has a bolt released at will by a spring
IPC: A63C9/085
Filed: 1975-03-13
Abstract: The reinforcement is for one end of a sole plate of a releasable ski fastening. A bolt holds the end of a sole plate in a locked position on the ski and cannot be moved to the release position in the use psotiion and during a safety release by the sole plate. However, it can at will be moved into its release position by setting the sole plate against the force of a spring. The sole plate can be released wither by the front or by the back, sideways or upwards. The diagonal end of the sole plate is surmounted by a bolt, mounted in sideways slots of the reinforcement, against the force of springs. Covers prevent the penetration of ice, snow and dirt into the slots.

Title: Two-dimensional control stick for tractors and excavators - has orthogonal bars bending springy metal strips to short out resistors
IPC: G05G9/047
Filed: 1975-04-16
Abstract: The two-dimensional control stick, for tractors and excavators etc. consists of a joy stick with two orthogonal degrees of freedom. It engages via a rod (14) in slots (32, 34) in two orthogonal bars (28, 30) at its lower end. One end of each bar is loaded by two opposing sets of helical springs (36) fixed to the sides of the housing. To avoid using sliding potentiometer arrangements to generate the position-dependent control signals, the other ends of the bars are provided with rollers (42, 44) that deform springy curved metal strips (46) acting as electrical bridges. These strips progressively short out resistors in chains of resistors mounted on the sides (24, 26) of the housing as the bars move farther from their equilibrium position.

Title: Can end opening device - has tear off tab which allows outer ring to be torn off around most of periphery
IPC: B65D17/50
Filed: 1975-11-21
Abstract: The combined lid is made up of two elements soldered together. A top ring has a finger tap (13) in the centre.

Title: Air circulation modifications in cement clinkering plants - giving improved heat exchange between heat input and heat output
Inventor: GHESTEM GERARD
IPC: C04B7/47
Filed: 1975-12-12
Abstract: Dry method of cement mfr. using a preheater heated with exhaust gas from a tubular rotary kiln, and a collection chamber where particles are partly calcined, then introduced into the kiln. The clinker produced is cooled with fresh air followed by sec. air in the furnace, and calcining chamber. The novelty is that the fresh air is passed several times through the clinker layer, before being introduced into the hot zone of the precooler. This is divided into 2 parts at different temps., one >1000 degrees C and the other contg. the sec. air, at a lower temp. The temp. of the air in the hot zone of the preheater can be increased from the 850-900 degrees C used in prior art.
