Title: Low tension weft yarn feed device for looms - having accumulation chamber from which weft yarn is withdrawn
IPC: D03D47/00
Filed: 1972-10-09
Abstract: Pref. two parallel feed rollers are located within a perforated cylindrical stationary shell and axially spaced radially extending separator walls (pref. defined by a single helical wall) are arranged between the drive rollers and the shell. Weft yarn is wrapped around the drive rollers so that each yarn turn lies in a space between two adjacent separator walls and a radially outward air flow is set up to force each yarn turn away from the drive rollers and against the inside of the shell whereby a loose yarn reserve coil is set up. When yarn is withdrawn from the reserve the yarn turns tighter and the drive rollers which then draw more yarn into the device. Pref. one of the rollers is hollow and perforated and the radial air flow is set up by feeding pressurised air to the hollow roller. Yarn can be withdrawn under low tension without the risk of entangling.

Title: Cleaning cutting tools and similar metal parts - using alkaline bath contg. jets spraying clean liq. onto parts before drying
Inventor: GUENTERT SIEGFRIED
IPC: C23G3/00
Filed: 1973-05-11
Abstract: The clean spray removes any dirt or scum on the parts. A closed tank has a bath of cleaning liq. (pref. alkaline) in its base, and a rotating drum is mounted on a hollow, horizontal pipe which can be connected to a hot-air blower. The drum and pipe can be lowered into, and lifted out of the bath in the way given in DT-OS 2119514, and hot air can be blown through a row of holes in the bottom of the pipe for drying the parts after cleaning. Alongside the row of holes is a tube which runs the length of the pipe and which also has a row of holes. After the drum has been lifted out of the bath, fresh, residue-free cleaning liq. (or distilled water) is sprayed onto the parts via the tube, thus removing any dirty liq. before hot-air drying. A pipe in the bottom of the tank leads to a pump and either to a drain or a filter which supplies clean liq. to a flexible tube which is led through the bath (for preheating) and then to the spray-tube. A flexible tube is needed to allow for the raising and lowering of the drum.

Title: Composite yarn formed from untwisted fibre sliver - around which tying yarn is wound helically at a point spaced from feed rolls by a distance less than the fibre length
Inventor: NORTHUP FRANCIS BRACKETT
IPC: D02G3/38
Filed: 1974-02-15
Abstract: A fibre sliver (e.g. polyester) is advanced between feed rolls through pref. a twisting bush at pref. the entry of which a tying yarn (e.g. nylon) is wound helically around the sliver. The distance between the feed rolls and the point at which the tying yarn is wound around the sliver is less than the staple length (e.g. 75 mm) of the fibres so that one of the ends of the fibres is held in the nip of the feed rolls whilst the tying yarn is wrapped around the other ends of the fibres. Pref. a Spandex (RTM) yarn is incorporated in the sliver and the sliver passes through an air nozzle between the feed rolls and the twisting bush whereby an air jet is directed along the sliver in the advance direction of the sliver. The composite yarn is used for knitting or wearing and is more uniform and stronger than conventional spun yarns. The method produces less waste, and the yarn can be produced at higher speeds.

Title: Oxygen refining of steel - measuring inlet and outlet temp. of cooling water in oxygen lance to indicate carbon content
Inventor: VRIES JAN SIJBREN DE
IPC: C21C5/46
Filed: 1974-10-02
Abstract: Process for controlling the refining of steel, where the difference between the inlet and outlet temp. of the coolant flowing through the oxygen lance is measured in order to obtain a specific carbon content in the melt on tapping; the gradient of temp. increase in the coolant is measured towards the end of the blowing period and, when a specific gradient is reached, a signal is emitted which ends the flow of oxygen through the lance. A specific gradient of temp. increase in the coolant flowing through the O2 lance is pref. also used to start the flow of oxygen at the beginning of the blow. The inlet and outlet coolant temps. are pref. converted into electric signals and, in the case of a recirculating coolant via a cooler, any pronounced variations in inlet temp. are filterd electronically before the temp. gradients are measured. The precise times for starting and finishing the blow are indicated by an electric signal and steel with a known carbon content can be obtd. on tapping.

Title: Electrically operated destroyer for cockroaches - in which the insects are killed immediately by short circuit induced by conductors
Inventor: LEUSCHKE EVA-RENATE
IPC: A01M1/06
Filed: 1974-10-09
Abstract: The shape and size of the device can be varied and is placed against a wall. The vermin enter through a slit the size and shape of which can be altered. The casing of the device is of fully insulated, non-conducting material such as plastic. A suction rubber prevents the vermin emerging between the casing and the wall. Once inside the trap, the vermin move upwards, attracted by a lure. The conductors with reverse polarity create a voltage. The body humidity of the vermin creates a short circuit. The electrical energy can be discharged continuously or at intervals to the conductors. A catchment channel catches the dead vermin, and a suction device automatically removes them.

Title: Toggle operated brake assembly - has shoes spring biassed onto drum releasable by solenoid lever
Inventor: BETZ ARMIN
IPC: F16D65/28
Filed: 1974-11-28
Abstract: A drum brake with two brake shoes (8, 9) is operated by a toggle lever (3) and a helical compression spring (12). A double acting cylinder (26) with flow control on each port is connected to the toggle lever (3) parallel to the operating spring (12). A solenoid valve is linked to both ports of cylinder (26) so that the throttle valve can be bypassed when the solenoid valve is open. When the solenoid of the brake disengagement unit (2) is energised, lever (3) is moved against the action of spring (12) and the brake opens. When a power failure occurs, the solenoid valve closes and a controlled application of the brake takes place due to the throttle valve.
