Title: Hand-operated rope winch - has catch on anchoring hook holding release lever engaged under load
IPC: B66D1/58
Filed: 1973-11-16
Abstract: The winch has an anchoring hook and rope gripping jaws in two blocks moved to and fro along the rope by a hand lever, alternately gripping and releasing the rope. A release shaft (25) frees the rope and is held in the engaged position by a locking catch (30) secured by the anchoring rope (22, 23) engaging the hook. The reciprocating actuating arms (15, 16) are actuated by a lever fitting over one or the other and with a weakened portion at the load end so as to restrict the force applied.

Title: Pneumatic jet for puncturing blow moulding parisons - to eliminate needle wear and provide forced cooling
IPC: B29B11/10
Filed: 1974-04-26
Abstract: Inflation of tubular parisons trapped with sealed ends in a blow moulding tool cavity by applying a coarse blunt pneumatic nozzles against the parison wall and applying a high pressure jet to puncture the wall and inflate the parison. The mould wall features a vent passage into which a local part of the wall of the moulding can distend and burst if the pressure inside the moulding is raised sufficiently after dilation of the parison. Pref. the vent is aligned with a relatively thick portion of the moulding wall or a pinch weld: the thicker matl. remains relatively hot and soft and easier to burst than the thinner, more rapidly chilled sections of the moulding. Process avoids the reciprocating mechanisms and tool wear and replacement problems associated with use of thin, sharp hollow needles to physically penetrate the parison wall. The through flow of air from the pneumatic nozzle through the moulding and out of the vent can serve to accelerate cooling and remove volatile odours.

Title: Disc shrunk turbine shaft - has reduced clamping force near ends of disc produced by slight taper
Inventor: BRAY JEAN-CLAUDE
IPC: F01D5/02
Filed: 1974-12-16
Abstract: The clamping forces of a shrunk connection are usually larger near the ends of a shrunk part than in the central region. This is due to the fact that the shaft deforms more over the central region. The proposed arrangement has the result that the clamping forces near the end regions are reduced. The bore of the part to be shrunk has a central parallel section and two tapering end sections. The degree of taper in the end sections is between 0.5 to 5 per thousand. The axial length of the cylindrical section is approx. twice the axial length of each tapered section.

Title: Coupling for forward drive and spring reversal for photocopier - has input pawl-coupled to output, pawl release controlled from input via transmission
IPC: G03B27/52
Filed: 1974-12-20
Abstract: The coupling comprises an input disc freely rotating on an output shaft on which the output disc is fixed. The input disc is driven and carries a spring-loaded pawl capable of engaging a recess on the output disc. The shaft is spring loaded by a torsion spring which is tensioned during forward drive. The input disc is integral with a pulley which, via belts and an intermediate shaft, drives a cam which is so arranged that it can lift and thus release the pawl. On being lifted, the pawl is held in the lifted position by a guide track for a pre-determined period to allow the shaft to rotate backwards under the action of the torsion spring. The relative numbers of revolutions for forward and reverse motion are determined by the belt transmission ratio.

Title: Hollow window or glazed door frame profile - is formed by bending steel sheet and forming groove for seal
IPC: E06B3/16
Filed: 1975-02-10
Abstract: A hollow profile for forming window or door frames is bent from sheet steel. The steel is first bent between rolls to form a stepped end with a sloping part the other end and further rolls form further bends in both ends, resulting in a section which is still horizontal. Further rolls begin to bend the sides up, and finally the sides are bent inwards to form a hollow box, the two ends being spot welded together. After cutting to length, doubled over glanges which extend from the box are bent over to retain a resilient seal. The door or window is fitted with double glazing panels and a water sealing frame is fitted. The seals of pairs of profiles forming the fixed and movable parts of the frames engage projections on the other profiles of the pairs.

Inventor: CHALIER CLAUDE
IPC: G01J3/453
Filed: 1975-06-30
Abstract: A phase correction method for use in real time Fourier transform spectrometers is described. The displacement of one of the spectrometer mirrors is monitored using a Moise fringe system. An electronic system ensures the coincidence between a point zero path difference and a pulse produced by the system. The analogue value of the interferogram provided by the detector (3) after amplification (4) is converted by an A/D voltmeter (5) and the digital value is fed to the computer (6) which performs the Fourier transform. The computer compares the Moire pulses with clock pulses from the A/D converter.

Title: Solar-energy-assisted hot water storage - heating medium blocked until heat surrendered to stored water, then replaced
IPC: F24J2/40
Filed: 1975-08-27
Abstract: After the heat-exchanger has been filled with heating medium heated in the solar heat collector, circulation of the medium is blocked until this portion of the medium has largely given up its heat to the stored water. Circulation is then released until the cooled medium has been conducted away from the heat-exchanger, when it is replaced by a following flow of heated medium, for a repetition of the process. There is one heat sensor in the solar heat collector in the area of the run-in pipe socket and a second near the hot water store in the heat-exchanger's return connection, the sensors being effectively linked to the circulating pump so that this is switched off until the returning heating medium has cooled to a prescribed temperature differential relative to the run-in.

Title: Spark erosion machine with automatic control - has optical reading head to control cutting tool through electronic circuit
Inventor: VASILIEV V S
IPC: B23Q35/128
Filed: 1976-02-02
Abstract: The spark erosion machine is guided by an optical reading head mounted on a slide which can be moved in two directions by motors. A feed back signal from the reading head is transmitted to the amplifier which transmits corresponding signals to the store and the coincidence circuit. The store also receives signals from the impulse generators and switches. Signals from the coincidence circuit are transmitted through the amplifiers to the motors which guide the tool and to the motors which guide the optical reading head. If the reading head departs from the outline of the template, a signal is generated which corrects the position of the reading head and the tool.

Title: Alternator circuit for motorcycle - with separate windings for battery charging main lights and ignition
IPC: H02J7/14
Filed: 1976-05-31
Abstract: The alternator for the motorcycle has separate windings for the battery charging and the main beam. One winding supplies the battery via a first rectifier as well as the brake lights via a tapping in front of the rectifier. The second winding and a second rectifier supply the DC powered lights on the machine. These are direction flashers etc. A tapping from this line powers the main beam with AC. This ensures that both DC and AC circuits receive sufficient charge, with no danger of the battery being overcharged during daytime use. The alternator has a common pole wheel and a third winding which powers the ignition.
