Title: Spark ignition engine angular speed instrument - has galvanometer connected by circuit to contact breaker of ignition system
IPC: G01P3/48
Filed: 1975-09-05
Abstract: An electronic revolution or turns counter instrument is used to determine the angular speed of rotation of a spark ignition internal combustion engine. The instrument has a galvanometer (19) to display the speed of rotation. The ignition contact breaker (v) of the engine provides a signal proportional to the speed of rotation. It has a circuit with a resistor (10) and a Zener diode (11). There are also two parallel lines (16, 17) which form part of the circuit. One line (16) had a diode (18) which allows current to charge a capacitor (13). The other line (17) has a diode (20) and a galvanometer (19) which allows the discharge of the capacitor (13). The galvanometer (19) can detect pulses corresponding to the opening and closing of the breaker (v) and the charge and discharge of the capacitor (13).

Title: Thread guide, esp. for false twist texturing machines - has endless belt round an idler pulley driving coils
Inventor: DUPEUBLE JEAN-CLAUDE
IPC: B65H51/10
Filed: 1975-09-18
Abstract: The yarn feeder is of the type having a driving cylinder against which a pressing roller is held firmly in contact; the axes of the two being parallel. Above the pressing roller and axially parallel to it also, there is an idler pulley, and an endless belt runs on the two. The axes of all three rotating details are in the same plane, and a belt tensioning device is also provided. The feeder is esp. applicable to false twist texturing machines and stretch texturing machines, being simpler in design and threading up, etc. than conventional guides. It takes up very little room and is cheap to produce. In the event of yarn breakage there is no twisting around the roller. The idler pulley is driven by the belt and not by the yarn and the full length of the coils of yarn is driven by the belt.

Inventor: WEHDE HEINZ
IPC: F16C39/06
Filed: 1975-12-05
Abstract: 1525489 Automatic control of position TELDIX GmbH and ARTHUR PFEIFFER VAKUUMTECHNIK WETZLAR GmbH 28 Nov 1975 [6 Dec 1974] 49088/75 Heading G3R [Also in Division F2] A rotor, stabilized in a radial direction by active and passive bearings, includes a bell shaped portion into which at least partially extends a subassembly of a rotor position sensor, a circuit for damping rotor radial oscillations and a stator of an electrial drive motor. As shown, for use in a turbo-molecular pump, an inductive sensor 42 detects the position or speed of rotor 5 and controls at least one electromagnetic winding 35 accordingly so as to damp radial rotor oscillations. The winding 35, which has an E or U shaped core, co-operates with a ferromagnetic ring 40 on the bell shaped portion 39 of the rotor, that also houses a rotor drive (e.g. brushless) motor. The output of sensor 42, which can be the same winding as control winding 35, is filtered before amplification so that only mechanical resonant frequencies are damped. The passive bearing 11 comprises a permanent magnet 12 and ferromagnetic parts 14, 15, 18 or alternatively parts 14, 15 may be omitted and ring 18 made from a permanent magnet. The active bearing 23 includes a ferromagnetic portion 30 on the rotor and an electromagnet 24 that regulates the rotor axial position as sensed by device 31, which may be inductive, capacitive or photo-electric. The subassembly cooperating with the bell shaped portion of the rotor makes the moment of inertia at the end of the rotor greater than this moment at the middle of the rotor.

Title: Repeatedly closable bag of heat sealable plastics film, with handle - is opened by tearing off the handle, and re-closed by means of closing tapes
Inventor: NORDSTROM JOHN EUGENE
IPC: B65D33/10
Filed: 1976-04-26
Abstract: A bag made of heat-weldable plastics film e.g. polyethylene film has welded gusseted walls and bottom, and top flaps with handle holes. Each wall has seams with a closing tape in it. The tapes are welded into the sidewall weld seams each of which has an opening through which the tape may be pulled for closing the bag. The walls have parts extending from the underside of the seams to the top side and covering the openings in the seams to the top side and covering the openings in the seams to their inside in order to close the openings w.r.t. the interior of the bag. These parts of the walls have, above the seams, handle flaps with finger hole for carrying the bag. The flaps have weak lines extending between the finger hole and the seam from 1 side of the bag to the other so that the flaps may be torn off along the weak lines. The finger hole and weak line are spaced from each other so that the flaps may be welded together. This enables the bag, once it has been filled, to be closed along a line extending between weak line and finger hole from one side of the bag to the other.
Patent FR-2351773-A1 (FR)
Title: Mandrel turret for making-oriented blow moulding containers - using mould traverse instead of mandrel motion during stretching
Inventor: LOUVEAU GERARD
IPC: B29C49/12
Filed: 1976-05-18
Abstract: Machinery for producing oriented blow-moulded containers involves a turret with one or more mandrels for supporting a tubular parison and gripping it by the neck. The mandrels can turn successively via a parison mould tool anda parison conditioning tool to a position where a deep mould allows the parison to be stretched longitudinally before being dilated. Stretching is effected by driving the mould tool coaxially over the mandrel, to force the neck clamps along guide bars away from the mandrel head and towards the turret axis. After the parison has been stretched, dilated and chilled, the mould tool is withdrawn and parted to allow the moulding to be moved by the turret to an ejection station. The machinery design is simpler than for equipment involving turrets with reciprocating mandrels to obtain parison extrusion.

Title: Hot air generator for shrink wrapping - has gas burners inside portable air duct to soften plastics foil
Inventor: FABRIS ALBINA
IPC: B65B53/06
Filed: 1976-06-11
Abstract: the hot air generator is used to shrink plastic foils for wrapping objects, and has a number of gas burners located inside a rectangular sheet metal cage. The burners are mounted on two parallel bars which form manifolds for the gas supply. A partition wall isolates the gas flames from the manifold and burner compartment so that the necessary air supply to the mixing tubes of the burners is not impaired. The handle of the hot air generator includes regulator valves for the gas supply. A piezo-electric spark generator is also located inside the handle so that the burners can be ignited by operating push button.

Patent FR-2325751-A1 (FR)
Inventor: GALPERIN A L
IPC: D03D47/26
Filed: 1976-09-23
Abstract: After the filling of the weft-thread carriers (5) and the cutting-off of the weft thread, a portion (a) of the weft thread is drawn back, by a tension element (7) and a thread guide (3) intended for winding, in the direction opposite to the feed direction. For this purpose, the distance between the thread guide (3) and a breaking point (8) is briefly increased by moving the breaking point (8) away from the thread guide (3) by an amount corresponding to the length of the part of the portion (a) to be drawn through. This takes place, for example, by briefly raising the breaking point (8) and the bobbins (2). The thread thus always lies on a straight line between the thread guide (3) and the breaking point (8), so that additional mechanical effects on the thread are avoided.

Title: Offset print machine for repeat patterns - has two plate cylinders which are used for successive parts of pattern
IPC: B41M1/18
Filed: 1977-02-16
Abstract: An offset print machine is for priting repeat patterns on a web, e.g. for patterned wallpaper.
