Title: Automatic firearm with increased capacity magazine - three rows of cartridges in magazine
IPC: F41A9/68
Filed: 1973-06-20
Abstract: An automatic firearm using a magazine with three rows of cartridges which gives an increase in its capacity, has a breech mechanism with a sliding bolt (1) with a projection on its underside which operates a cam device (2) at the rear of a slider arm (6) tensioned by a spring (14).

Title: Portable clothes drying rack - with threaded spindle in supporting arm to execute mounting clamp action
IPC: D06F57/12
Filed: 1973-10-12
Abstract: The supporting arms, linked to each other by a number of parallel telescopic rods, are fitted with clamps to fit over a balcony wall or a heating wall, and be screwed home. The action of the screw spindle, through the drilling in the supporting arm, draws one leg with pliable buffers against the supporting structure, against the other leg which carries the web supporting plate to give supporting rigidity to the arm. This provides a robust drying rack, which is easily erected in a number of locations, with a good aesthetic appearance.

Title: Automatic winding and clamping of dynamo windings - with winding machine with an automated tool for leading the windings through the correct commutator clamp slots
IPC: H02K15/09
Filed: 1974-04-22
Abstract: The device is for winding and clamping dynamo armature windings automatically and guiding them tightly through the correct commutator clamping slots. The system is more rapid and therefore cheaper than the traditional method of guiding and clamping the armature windings. The winding machine guides the two wires from spools by a complex mechanism through the armature slots. At the end of each slot each wire is guided into the appropriate commutator clamp slot, along the commutator, round the shaft of the dynamo, back along the commutator and into the next armature slot. This is achieved by a cup shaped mechanism with two longitudinal slots and shaped guides which fit over the commutator. The wire is passed through the slits in this device and guided along the correct path by separated clockwise and counter clockwise movements of the arrangement.

Title: Stackable cardboard packaging tray - has ends inclined inwards and sides with end extensions inclined outwards
IPC: B65D5/00
Filed: 1974-05-21
Abstract: The tray is made from a cardboard blank and comprises two short sides (4, 5) with end flaps (2a, 3a). The two long sides (10, 11) are separated from the flaps, when the blank is flat, by cutouts which give the long sides an outwards and upwards inclination when the tray is erected. The flaps are secured to the long sides by gluing or stapling, so that their fold lines register with the edges of the long sides. The short sides then incline inwards and upwards. Tabs (12, 13) underneath each short side and raised sections (10b) on the long sides are provided for stacking.
Patent FR-2273712-A1 (FR)
IPC: B29C65/00
Filed: 1974-06-06
Abstract: Equipment for enclosing articles between a porous support tray and a cover made of vacuum formed thermoplastic film. The tray may be loaded on a trolley which can then locate the tray over a suction table. The film is held between two clamping frames located above the table and below a series of radiant haters. While the tray is being loaded, the heaters are kept running, but at a relatively low power and shielded from the film by mobile screens. When the loaded tray is over the table, the heater power is automatically increased, the screens deflected, and the film heated. After a preset heating cycle the frames holding the film descend to the level of the vacuum table and vacuum is applied to shape and seal the film over the tray. Design avoids stop-start operation of the heating and vacuum pump systems without overheating the film.

Title: Instantaneous adaptive delta modulator for data transmission - for data transmission has comparator with sampling and memory circuits and has integrator with variable gain
Inventor: SOURGENS JACQUES
IPC: H03M3/02
Filed: 1974-07-01
Abstract: An instantaneous adaptive delta modulator and demodulator is used for transmission systems. The modulator codes an incoming signal train into binary form and includes the ability to decode using an integrator having a variable gain. The modulator includes a comparator producing an output which is a function of the difference between the input signal train and a reference level. A clock source synchronised sampling circuit converts the comparator output into binary form. A local integrating demodulator has a gain >=3 and a memory providing a temporary store for the binary signals. A logic circuit provides the gain values for each sample.

Title: Safety interlock for quarter turn stop cock - has cover retained by half shells holding sleeve with sliding button held by ball operated by rotating ring
IPC: F16K35/00
Filed: 1975-09-30
Abstract: The stop cock wheel is removed and replaced by a cover (4) retained by two half shells which surrounds the valve body (3) and also hold a sleeve (7) in place over the downstream pipe union. A sliding button (5) registers in a notch cut in the skirt of the cover when the valve is closed and is itself held in this position by a ball. The ball locks the button by being forced upwards into a recess in the base of the button, under the action of a rotating ring. Until the cover sleeve is replaced, the ring cannot be turned to free the ball and tap. In addition, the button when pulled back, registers in a notch in the sleeve, which cannot then be turned accidentally.
