Title: Sequence controlling mechanical actuator partic. for valves - in automatic regeneration process for water treatment plant
IPC: C02F1/42
Filed: 1973-05-30
Abstract: Operation sequence controlling, mechanical actuator in which an actuating link derives its motion from a timing gear which has arcs of teeth meshing with a constantly rotating drive gear, the timing gear arcs of teeth alternating with toothless arcs so that drive ceases as the timing gear presents a toothless arc to the drive gear. The drive gear provides a continuous rotation to a meshing control gear having projecting studs which can be adjustably positioned so that rotation of the control gear will cause a stud to hit one arm of a bell-crank lever which pivots to effect disengagement of a spring-loaded catch from locking with the timing gear which is thus freed to rotate as the second arm of the bell crank lever pushes against a stud in the face of the timing gear to bring the next arc of teeth into mesh with the driving gear. The mechanism is used to automatically control the sequence of process operations, esp. opening and closing valves in regenerating a water softening plant.

Title: Lifting equipment torque limiting device - has anti-unwinding device engaging on motor failure or reverse rotation
IPC: F16D7/00
Filed: 1973-05-23
Abstract: The device is particularly for use with hoists, and has an anti-unwinding device between the shaft of the electric motor and the intermediate shaft driving the drum shaft. This operates automatically in the event of motor failure, or if the drum shaft attempts to rotate in the opposite direction under the effect of the load. It can be composed of a gearwheel meshing with a pinion on the motor shaft, a hub on the end of the intermediate shaft with a friction washer between it and the gearwheel, together with locking devices on hub and gearwheel and connection devices between them. The locking devices can be in the form of pawls pivoting on the gearwheel by means of pins held in place by circlips.

Title: Slacks for pregnacy wear - degree of overlap of two front portions is variable
IPC: A41D1/21
Filed: 1973-06-21
Abstract: Slacks for ear during pregnancy have two portions at the front which extend from the crutch to the belt, these extending from the sides of the slacks and overlapping.

Abstract: A laminated structure comprising a polyolefin core sheathed in a polyamide skin is produced by first injecting the polyamide compn. into a mould and, prior to solidification of the central zone of the compn., injecting the polyolefin into the mould to cause expansion or spreading of the polyamide towards the mould cavity periphery. Into either of the two polymers is incorporated (1) a (co)polypropylene grafted with an unsatd. dicarboxylic acid or anhydride and opt. (2) >=1 cpd(s) chosen from aromatic monocarboxylic acids, OH-contg. monocarboxylic acids which can form a cyclic anhydride, polycarboxylic acids with is not >4 COOH gps. and is not >1 atom of an element other than C, H and O, and their anhydrides. The grafted copolymer (I) contains >=1 wt.% of C=O in the acid or anhydride gps. of (I) and in the free acid or anhydride, the amt. of (I) is 20 wt.%, based on the polymers of the compn., and is such that, together with the free acid or anhydride, the compn. contains 0.02-1% wt., based on the polymers, of acid and/or anhydride gps. (expressed as C=O). (I) together with the free acid ensures good adhesion between the polyolefin and the polyamide and does not have to be separately injected.

Title: Extractor using four work cylinders - for removing the baseplate from steelworks converters
Inventor: LEROY PIERRE
IPC: C21C5/48
Filed: 1975-12-12
Abstract: The baseplate is wedged in its holding ring which is fixed on the converter casing. The device consists of four extractors located at internvals of 90 degrees round the baseplate. The holding ring is fitted with four pairs of lugs contg. grooves contg. a slide. When the baseplate is to be removed, the slides are moved to a working position and a work cylinder contg. a hollow piston is mounted on each of the four slides. A rod is fed through each piston and screwed into the baseplate; the four work cylinders are then used to draw the baseplate out of its holding ring. The movement of the four work cylinders is pref. synchronised by any known means. Used on top- or bottom-blown converters after the refractory lining on the baseplate has worn and must be replaced. During refining, the refractory on the baseplate bonds to the converter lining so considerable force is needed for extn. The invention provides this force smoothly and quietly.

Title: Thermoplastics tubular film prodn. - with pre-expansion in die and internal air cooling before cooling mandrel
IPC: B29C48/90
Filed: 1976-02-23
Abstract: Prodn. of tubular film involves extruding molten thermoplastics (I), cooling with a directional gas stream so that it (partly) sets and passing downwards over a cooling mandrel. (I) is pre-expanded in the die before extrusion and the press. inside the tube is kept constant at 0.254-2.54 cm water column. Cooling is carried out continuously with a high speed air stream (II), from a slit in the cooling mandrel, the slit being at an angle of 25-35 degrees to the horizontal, in an amt. of 2.83-7.08 Nm3/min. (II) cools the inside of the tube and provides an air cushion between this and the mandrel, preventing sticking. High quality film can be produced in relatively high amts.

Title: Switching element fields coding - uses electronic hysteresis for data keyboards, using minimal integrated circuitry
IPC: H03K17/98
Filed: 1976-11-24
Abstract: A device is used for coding a switching element field, e.g. the input keyboard of a data processing device. It is designed to incorporate electronic hysteresis whilst using a minimum of integrated circuitry. Hysteresis ensures that a key must be depressed for a sufficient time before having an input effect so as to eliminate data keying errors. The switching elements have negligible impedance in the closed position and high impedance when open. A circuit connected to the switch matrix, a coltage source, and a signal amplitude detector (20), conducts a periodic assessment of the switch conditions which are different voltages according to the switch positions. The conditions are stored, and when a closed switch is detected the detector sensitivity for that switch is altered.
