Title: Wax removal device for skis - has ski support rollers, IR heater and heated scraper blade
IPC: A63C11/08
Filed: 1974-04-26
Abstract: The infra red heater (8) with its case (9) is mounted on the frame (1) along the axis of the aparatus and heats the ski sufficiently to soften the wax, which is then removed by the scraper plate (10). The ski is guided by two rollers (6, 7), mounted on adjustable rods (4, 5), which run along the groove in the ski. The scraper plate is made of thermal conducting metal and is pointed. The plate is heated by heating elements connected to the plate by two thermal conducting rods. The layer which is removed is deflected by another plate through a hole (17) in the frame into a collector.

Title: Isolating switch for very high currents - esp for the short circuit of defective electrolysis cells
IPC: C25B9/04
Filed: 1974-07-15
Abstract: Disconnecting switch for high currents, esp. for the short circuit of electrolysis cells, comprises (a) a bridge device with mobile contacts located between two detachable connecting arms which can be linked to the cell; (b) a support shaft on which the two arms can pivot and also move sideways between a forward, connecting position and a retracted position; and (c) coupling plates fitted on the arms. The novelty is that the bridge device consists of two spaced plates facing each other and carrying fixed contacts, and the space can be bridged by the mobile contacts carried by one of the plates. The device is used e.g. to isolate a defective cell in a row of electrolysis cells, and operates efficiently even with currents above 120 kA.

The ring or disc is built onto the arms of the crankshaft sections, and serves as the outer liner or cover for the journal of the friction bearing. Its diameter is greater than the maximum diameter of the crankshaft. The bearing shell is cast in the housing. It has a groove with at least two radial lubrication orifices. The bearing shells are located together by a peg. The outer diameter of the ring is between 5.1 and 6.0 times the width of the bearing.

Title: Perforated cork plate production process - stamps out by punch to produce pattern (PT170775)
IPC: E04F13/10
Filed: 1974-12-20
Abstract: The process produces plates with a decorative effect, and consists in stamping them out with the aid of punches to produce the desired pattern. A number of different plates can be stamped out at the same time with the same pattern. They can then be placed on a support of one or more colours so as to bring out the pattern more clearly. The process allows a much wider variety of patterns to be produced than if the openings in the plates are merely drilled out. The support can be in the form of a wall, floor, ceiling or furniture, previously painted in one or more colours.

Title: Mixing device for enriching skim milk powder - for fattening of calves using fatty materials
IPC: A23C11/06
Filed: 1975-02-25
Abstract: Mixing device is intended for the mfr. of an enriched powder partic. for use in the feeding of calves; the milk traditionally used can be replaced by a water-soluble powder contg. nutritive materials such as lard, suet, palm or coconut oil mixed with a base powder of skim milk. The device comprises a horizontal tunnel which is closed at each end by transverse walls. An assembly of air boxes is fed with cold air through ducts; the boxes open beneath an inclined distribution cloth with a 6 degrees slope. Four filter boxes are mounted at the top of the tunnel and connected to ventilating fans. The base powder and the fatty liqs. are mixed and introduced into the tunnel via an endless screw; the mixt. meets the upward flow of cold air and the particles formed are maintained in suspension in the upper part of the tunnel until they are evacuated at the rotary air air-lock where the air delivery is less than at the introduction end of the tunnel. The cold air ensures the crystallisation of the fatty materials so that the final powder is non-caking. The powder obtd. is perfectly sol. in water; it gives good animal husbandry results in the feeding of calves.

Title: Round iron suspension device - bent part has bending strength corresponding to tensile strength of bolt shank
IPC: F16L3/14
Filed: 1975-03-25
Abstract: The method of manufacturing a suspension device or roof bolt, the bent part of which has a bending strength substantially corresponding to the tensile strength of the shank of the device or bolt made of commercial round iron, is characterised in that the device is made of one single roundwork piece. The roundwork piece is cold bent to form an end the hook part in the shape of a closed, suitably oval ring, the largest part of which is extending, laterally to the longitudinal direction of the shank. The material of the ring is pressed or rolled by cold working perpendicularly to the plane of the ring and substantially up to the straight part of the shank, so that the section of the work piece in the pressed part becomes almost rectangular. The end of the ring is skewed laterally perpendicularly to the plane of the ring (cross-set), so as to form an opening sufficient for engaging a line, a chain or any other attachment means intended to carry a load.

Title: IC engine valve cam follower - has body with stepped bore housing spring acting on piston with recess for push rod
Inventor: SOUBRE RENE
IPC: F01L1/245
Filed: 1975-09-26
Abstract: A cam follower (1) is displaced by a cam (C) and in turn moves a push rod (3). The cam follower body (2) has an inner cylinder (5) with three sections (5a,5b,5c) of increasing diameter. The narrowest section contains a spring (7) which presses on a piston (4) in the next section. When the spring is fully compressed the back of the piston seats on the ridge (5d) between the two cylinder sections (5c,5b). The front of the piston has a semi-spherical recess in which the end (3a) of the push rod (3) seats. As the tappet wears, the spring pushes the piston forward, and with it the push rod to take up the clearance resulting from wear.

Title: Instant picture camera with hand operation facility - has ratchet in gear train to turn rollers for cleaning or extract photograph if motor fails
Inventor: IVESTER ANDREW S
IPC: G03B17/52
Filed: 1975-11-12
Abstract: After the photographic exposure, a battery-driven motor drives one of a pair of squeeze rollers which spread the chemicals over the photographic surface and eject the finished picture. An extra facility allows the rollers to be turned by hand, e.g., for cleaning them, or to extract the picture if the battery fails to drive the motor. The hand operation is relieved of the inertia of the electric motor by including a ratchet in the gear train between squeeze roller and motor. The ratchet wheel (54) has inward-facing teeth (40) and is made integrally with the pinion (34) that drives it. The pawls (46) are carried on a pair of curved arms mounted on the ratchet wheel's axle (36) and are also integral with their pinion (48).

Title: Hydraulic coupling with variable speed reduction ratio - has valves to control volume of fluid retained in coupling housing
Inventor: LAROCHETTE GILBERT
IPC: F16D33/10
Filed: 1976-02-27
Abstract: The hydraulic coupling has an input shaft (10) driving an impeller (1) which imparts energy to the fluid which in turn drives the turbine. The ratio of the turbine speed to the impeller speed can be controlled by controlling the volume of fluid circulating between impeller and turbine. The volume of fluid is controlled by a number of valves (12) which are normally held closed by fluid supplied from the valve (8). By shutting off the supply of fluid to the valve (12) the internal pressure opens the valve and partially drains the coupling of fluid. The number of speed ratios of the coupling is one greater than the number of valves (12).

Title: Temp. compensated thermal overcurrent rip - has coupling switching bridge with rotary plate-shaped element reaching bimetal strip (NL070976)
IPC: H01H71/22
Filed: 1976-03-02
Abstract: The thermal overcurrent trip with temperature compensation is intended for a circuit breaker containing an overcurrent bimetal element, affected both by the current flow and by the ambient temperature, as well as at least one compensation bimetal element, affected only by the ambient temperature. The two bimetal elements are coupled together by a switching bridge (2), containing a rotary mounted plate-shaped member. The latter reaches into the space between the spaced ends of the bimetal strips (1, 3), in parallel planes, by a part located on one side of the member axis of rotation. In this way the rotary member part fills partly the space between the two bimetal strips. Preferably the switching bridge abuts the free end of one bimetal strip.
