Title: Apparatus for sewing machines - gives automatic threading of the needle
IPC: D05B87/00
Filed: 1974-05-13
Abstract: Appts. used in conjunction with a sewing machine for theading the needle automatically, has a rod lightly supported in the frame of the machine case and has a body smaller than the lateral curved part of the needle, and a thickness suitable for the needle eye. The rod is connected to a manually operated device which initially causes the rod to drop to a posn. limited by vertical or lateral adjustment to line the curved part up with the eye of the needle, and secondly on rotating the rod, moves the curved part to penetrate the needle eye, the curved part taking the thread through the eye and being withdrawn after releasing the thread.

Title: Expansion system for reversible refrigerator - has expansion valves for refrigerator and heat pump in a common system
IPC: F25B13/00
Filed: 1974-06-14
Abstract: The expansion system for a heat pump or refrigerator ensures that the flowing refrigerant is expanded to such an extent that the efficiency of the heat pump is optimum for either flow direction of the refrigerant. In a preferred version the heat pump has, in addition to the expansion system, a pair of heat exchanger which can be used optionally as a condenser and an evaporator. A compressor is provided and aslo a valve for changing the flow direction. On flowing in one direction the refrigerant is expanded through a valve into a chamber which contains a moving valve which has a second throttling device. Hence the refrigerant passes through two throttles in series. When the flow is reversed the throttling device in the valve is bypassed and the refrigerant is expanded only through one throttling device to a smaller extent.

Title: Adjustable hinge-pin for strap-hinges - slotted holes for varying position and angle and reinforcing plate
IPC: E05D5/04
Filed: 1974-06-18
Abstract: An adjustable hinge pin for strap hinges consists of a base plate (13) and a pin (15) which serves as the axis for the hinge of a door or shutter. This pin (15) has on its lower section a cylindrical collar (17) which is welded to the base-plate (13). The base plate contains horizontal slotted holes through which screws are inserted into the wall. The fact that the holes are considerably wider than the screw heads means that the plate can be readily adjusted. A reinforcing plate (31) can also be used. The hinge pin can be easily fixed to any angle in the wall and adjusted so that any final adjusting of the door or shutter is eliminated.

Title: Recovering energy in an isotopic sepn. plant - by passing refrigerant through thermodynamic cycle incorporating turbine and recycle pumps
Inventor: HIRTZ ALFRED
IPC: F04D29/58
Filed: 1975-08-19
Abstract: Process for recovering energy in an isotopic sepn. plant includes a number of compressors in series each followed by a sepn. stage through which a fluid being enriched e.g. UF6 is passed. Each sepn. stage has a heat exchanger for cooling by a refrigerant fluid. The recovery of energy is carried out by bringing the refrigerant fluid from four or five stages together in parallel and passing it through a thermodynamic cycle. In the cycle it is expanded in a turbine directly coupled to the compressor of one of the stages. The turbine supplies about 65% of the power used by the compressor. The rest is supplied by an electric motor. A plant for carrying out the process incorporates the heat exchangers, an expansion vessel contg. gaseous and liq. refrigerant at the satd. vapour press., a turbine, a condenser, an extraction pump, and a circulation pump. The process reduces the need of electrical energy for the turbine and thus the need for a large alternator and the necessary accessories and supplementary civil engineering. The recovery of energy is 40-50%.
Patent FR-2330626-A1 (FR)
Title: Strip material glue jointing system - has guides adjustable for different widths and adjustable adhesive tape feed
IPC: B65H21/00
Filed: 1975-11-10
Abstract: System is for glued butt-jointed of lengths of strip material particularly photographic film. The film lengths are driven forward in lateral guides also adjustable vertically, so as to be butt-jointed together with the aid of a suitable length of adhesive tape. The guides are adjustable to accommodate different widths of film, as is the feed speed of the tape. A mechanism can be provided to move two lateral guides together and apart, while other guides acting in the vertical direction bear with very gentle and constant pressure against the arched portion of the film. A feed roller thrusts the tape forward in a guide to below a gluing head, and is coupled by a cam mechanism to the head, which moves up and down and is equipped with a tape parting knife. The tape feed and the guide adjusting drive are also coupled together.
Patent FR-2292658-A1 (FR)
Title: Means for applying stiff filament windings to a softer matrix - by using integral ancillary mandrels to control winding
IPC: B29D29/08
Filed: 1975-11-27
Abstract: The equipment is used for applying helically wound reinforcement filaments or cords about a tubular polymeric body mounted on a rotary mandrel. The mandrel is extended to support a cylindrical drum of calibrated dia. mounted concentrically on the mandrel axis. The reinforcing cord is led for several turns about the calibrated drum at intervals controlled by extending each turn to pass round a parallel shaft with grooves at the required intervals. The cord leaving the calibrated zone is led via hinged 'V' guide or an oblique pulley to a winding head which is tracked parallel to the body on the mandrel to apply windings to the pitch pattern(s) required for reinforcement. Used esp. for mfr. of small power transmission belts with transverse ribs of regular intervals by coating a longitudinally grooved mandrel, then applying the wound reinforcement followed by a further layer of matrix material before cutting the composite tubular body circumferentially to obt. several belts. The calibrated drum may be fitted to match the level at which the windings are to be applied to a substrate which may be of relatively low and non-uniform hardness. The drum is positively matched to the rate of rotation of the body of the mandrel, allowing high modulus filaments (glass etc.) to be applied more evenly than by use of separate devices to control filament tension or feed rate. The pitch is readily adjusted by changing the small sleeve on rollers on the parallel shaft, instead of having drums grooved for each combination of dia. and pitch required.

Title: Analgesic and antibacterial agents - esp. for dental application contg. a salicylic acid deriv. and a nitro-furan
IPC: A61K31/345
Filed: 1976-08-03
Abstract: New medicaments contain (a) a salicyl deriv. and (b) anti-bacterial cpds. of the nitrofuran series with synergistic activity w.r.t. analgesic and antiseptic properties. The ratio of salicyl deriv. to nitrofuran cpd. is generally 4:1. Typical salicyl derivs. are aspirin, diethylsalicylamide, salicylamide, and choline salicylate. Typical nitrofurans are 5-nitrofurfurylideneaminohydantoin and 3-morpholinomethyl-5-nitro-furfurylideneamino-2,4-imidazolidine-2- ,4-dione (nurfurfolin). The medicaments can be used for treating various painful or infectious syndromes, esp. in bone tissue and in the oral/dental area. There is mutual synergism between thesalicyl and nitrofuran components, so that both analgesic and antibacterial effects are increased. The toxicity of the medicaments is low, and they are practically without effect on blood clotting.

Title: Closed die forging press - having inertial nut screw mechanism for clamping dies during forming
IPC: B21J13/00
Filed: 1976-10-21
Abstract: A closed forming press incorporates a two-part die one part being secured to the press frame while the other is mounted on a slide moving in guides on the frame. During forming the dies are clamped together by a nut-end-screw combination one member is secured to the slide and moves linearly with consequent rotational motion of the other member. Mounted on the second member are two discs initially adjoining each other. The first disc is connected to the member while the second disc is connected to the latter by a self-locking thread so that the inertia forces resulting from the closing of the dies results in helical motion of the second disc relative to the first disc. The die parts are clamped by engagement of the second disc with the frame. A drive means subsequently returns the second disc with the frame. A drive means subsequently returnes the second disc to its initial position. The appts. provides improved press efficiency and reduced power consumption. It is used for shaping crown gear blanks, tees, crosses and bushings.
