Title: Worm drive arrangement for electromechanical load handling appts. - has at least one worm shaft with ball runners converting shaft rotation into reciprocal motion of telescopic arm
Inventor: BETZING VOLKER
IPC: B25J19/00
Filed: 1977-08-31
Abstract: Electromech. load handling mechanism has a telescopic arm (4) within which one or more worm drives are located and driven from brakable electric motor (80). At least one worm shaft has ball runners which convert the rotation of the shaft into a reciprocal motion of the telescopic arm (11). Lateral motion of a swingable port (6) of a horizontal support arm is also derived from the same, or other worm drive. The reciprocal telescopic arm (11) is non-rotatable with the fixed part (4) and the application of the drive motion to this is cushiond by spring pockets in both directions. The construction reduces the physical size of all load bearing parts.

Title: Rope spreader for loading of empty containers - has two secondary frames connected by rope to single crane hook
Inventor: WERTH HERMANN ING GRAD
IPC: B66C1/66
Filed: 1977-11-25
Abstract: The rope spreader is used for loading of empty containers by means of a single hook crane. The spreader frame has twist locks at each four corner points for connecting spreader to container top.

Title: Pressure roller used in paper and textile mfr. and dyeing industry - has rigid core with elastomer mantle which has circumferential grooves with bottle-shaped cross=section
Inventor: KILIAN WERNER
IPC: D21F3/08
Filed: 1978-04-05
Abstract: Pressure roller e.g. for papermaking, dyeing or wringing-out machines (as used in the textile industry) comprises a rigid roller core surrounded by an elastomeric (e.g. rubber or rubber-plastics) mantle, the latter being fitted with circumferential grooves that are either helical or coplanar with the dia. of the roller. The cross-section of the grooves is considerably narrower away from their bottom or valley than at the bottom which is suitably twice as wide as the top. Thus, the cross section of the grooves may be likened to the shape of a bottle with relatively narrow neck and spherically bulbous body.

Title: Connection between wall of thermoplastic container and insert - by blow moulding material around insert temporarily on arbor
Inventor: RAEDLER HELMUT
IPC: B29C49/04
Filed: 1978-06-08
Abstract: The thermoplastic material forming the deep-drawn or blow-moulded fuel tank of a motor vehicle, enclosed an internally screwed metal insert completely, except for the inner surface. The insert is screwed on to an arbor, which projects inside the mould to hold the flange of the insert some distance from the mould cavity wall. The insert together with part of the arbor, is enveloped by the thermoplastic material, and the pleat between the insert flange and the moulding wall, is then pulled by drawing back the arbor into contact with the moulding wall so that lips are formed enclosing the insert securely. The process is simple and the seal made is proof against ageing.

Title: Power generator driven by wind and sails - has movable masts adjusted automatically to suit wind conditions
Inventor: MAY BRUNO
IPC: F03D5/00
Filed: 1978-08-24
Abstract: The generator is mounted on a raft (50) floating in a lake (80). It can have a diameter of 2000 metres. Several sets of masts (200, 300) 400, 500) are mounted on the raft parallel to each other. In each set the masts (A, B, C, D) at the corners are fixed. The masts between them (2, 3, 4) can be moved laterally along guides (102, 100) by a hydraulic or mechanical mechanism. When not required they are thus moved until they are up against the fixed masts to form a single composite mast. Sails are furled on the masts according to requirements and produce rotation of the float. This is transferred to generators by a toothed wheel (33) round the float.

Title: Electronic antitheft device for vehicle - uses existing electrical controls in vehicle as combination lock to disable alarm
Inventor: BLATTL STEFAN
IPC: B60R25/10
Filed: 1978-10-10
Abstract: The anti-theft device is disabled by operating certain electrical controls of the vehicle in a given order, i.e. the electrical controls already present in the vehicle are used as an electronic combination lock. Only when an attempt is made to start the vehicle is its engine disabled. The voltages generated across the fuses serving the various parts of the vehicle may be used as logic signals for the switching-on of the control serving that part of the vehicle. Alternatively the fuses may be replaced by resistors to produce the appropriate logic signals. The wires leading to the electronic circuitry are soldered to the fuse holders. An additional circuit can be incorporated to release an alarm when the vehicle's bonnet is lifted.

Title: Ultrasonic wet grinding of coal - by forming a slurry and passing in through a chamber having a vibratory member
Inventor: TARPLEY JUN WILLIAM B
IPC: B02C19/18
Filed: 1979-01-16
Abstract: A method of comminuting solid particles consists in forming a slurry of solid particles are comminuted and cavitation induced in the slurry by contacting it with a resonant vibration transmitting member. This member is mounted to minimise loss of vibratory energy to its support and is positioned in the chamber so that there are no inactive regions of vibratory energy through which the slurry can flow. The liquid is then separated from the comminuted particles. The inventional provides apparatus for treating coal to remove contaminants which increases throughput efficiency while avoiding the necessity for high pressures and temperatures.

Title: Finishing rolling mill block for wires - with blanking-off flanges for idle last roll and gear units
Inventor: KLIEMANN PETER
IPC: B21B13/12
Filed: 1979-08-07
Abstract: When the end rolling mill units in a wire rolling block are to be cut out because larger gauges are to be rolled, the roll casing is closed by a spigoted flanged plate with a pass-through guide for the rod and restrictrs for the oil circuit. The gear casing is covered by a similar flanged plate which supports a countershaft with bearings. This allows the unused roll and gear units to be inspected for preventive maintenance and eliminates their wear, caused by running idle.

Title: Moving paper sheets humidifier - using electric field between atomising nozzles and counter electrode
Inventor: HARTMANN ROLF
IPC: B41L23/08
Filed: 1979-08-09
Abstract: A humidifying appliance for applying a liq. to paper sheets in motion, for example a solvent for printers ink in a hectographical printing process, uses an electrostatic spraying device to atomise the liq. and to transport it to the paper. The exit openings of the spray nozzles face a counter electrode and an electric field is maintained between them. The papers pass through the gap between them. This causes less liq. to penetrate into the paper than the felt pad method so that the liq. consumption is less. The liq. amt. depends less on the paper quality and can be readily adjusted.
