Title: Arc welding using planetary feeders for electrode wire - where each feeder motor has thyristor braking circuit
Inventor: AUER RUPERT
IPC: B23K9/133
Filed: 1977-04-09
Abstract: Arc welding appts. uses a consumable welding electrode wire a power supply which includes a wire feeder with planetary feed rolls driven by a motor (a). Between the power supply and the welding burner is a second feeder also with a driving motor (b). To obtain the same braking times for the two motors (a,b), a braking circuits is used directly adjacent to, and electrically connected with, each motor. The two braking circuits pref. each have a thyristor connected in parallel with the armature winding of the motor; and the thyristor has a control electrode which can be switched via a relay and a resistance connected to the positive pole of the motor, which has been switched off but is still rotating. To overcome the centrifugal force remaining in the planetary rolls after the motors have been switched off, so the same braking times are obtd.

Title: Nail or staple driver operating from mains supply - has double coils energised in same direction by thyristors
Inventor: MUELLER ERWIN
IPC: B25C1/06
Filed: 1977-06-28
Abstract: An electrically operated nail or staple driver has a plastic housing containing an electro-magnet with a sliding armature. The latter is attached to a blade which drives the nails or staples as they emerge from the magazine. the electro-magnet consists of two coils mounted one above the other and which have windings of opposite directions.

Title: Appts. for folding and welding thermoplastic-lined carton tops - giving reliable sealing of prefilled milk packs, etc.
Inventor: MOSSE RICHARD
IPC: B29C65/00
Filed: 1977-07-18
Abstract: The cartons are made of card having a thermoplastic coating at least on the internal faces of the flaps which comprise the top of the container and which creased and folded to resemble an open mouthed ridge with two convergant curved sloping faces.

Title: Flying shears for rod material - has hydraulic slide drive and acceleration piston with shorter stroke than slide
IPC: B23D25/04
Filed: 1977-09-01
Abstract: The mechanism serves for cutting to length rod materials travelling at high speed. A slide is provided with a chuck for clamping the rod by the action of an hydraulic cylinder. The slide contains also cross cut tools operated hydraulically. The rod material arrives at a photocell to start the drive by admitting hydraulic pressure to an accelerating piston. When the speed of the slide coincides with the speed of the rod a clamping cylinder on the chuck grips the rod, and subsequently tools cut off the required length.

Title: Safety binding for ski - has attachment point of heel fixing brought forward to reduce force required for release
Inventor: ZOOR REINHOLD
IPC: A63C9/085
Filed: 1978-02-23
Abstract: A safety binding for a ski has a toe fixing (5) which holds the ski boot rigidly in all directions. The heel fixing (6) allows the ski boot to move sideways in the event of the skier striking an obstacle with a sideways force (S). With the usual type of ski safety fixing the heel fixing is placed beyond the edge of the booth heel. By bringing this fixing forward to a distance (La1) from the toe fixing the moment arm about the toe fixing point (11) is reduced and so the force required to release the boot from the ski is also reduced.

Title: Mass exchange column packing - with specified parameters for crossing corrugations on adjoining sheets
Inventor: BAUERMANN HANS-DIETER DR
IPC: B01J19/32
Filed: 1979-05-25
Abstract: The packing of mass exchange columns consists of corrugated sheets, made of a tissue of plastic or metal fibres. The corrugations are inclined relative to the centre line of the column, but the sheets are arranged in parallel to the latter. The corrugations on adjacent sheets cross each other. The radii of the curvature of the crests and troughs of the corrugations are designed to equal 1/4 to 1/6 of the spacing from crest to crest. This provides a maximum of surface area for a given packing volume and prevents the merging of the fluid run-off into rivulets.

Title: Cyclonic separator for water streams - to removed suspended material using centrifugal action to separate less dense solids from liq stream and run them off via separate duct
Inventor: HIERONYMI KLAUS
IPC: B01D21/26
Filed: 1979-07-19
Abstract: Suspended solids are sepd. from a water stream by passing the water into a spiral channel which leads inwards from the outside. The centrifugal action causes the less dense suspended material to migrate to the inner surface of the spiral duct. Near the end of the duct a baffle is mounted to segregate the two streams and divert them into two separate outlets. The inner stream contains the solids while the outer stream contains the clarified water. Used esp. on plants and generating stations using large volumes of cooling water. Suspended debris is removed from such streams, fine material being removed efficiently as well as coarse material.
