Title: Spiral bound books prodn. - using one tool to cut spiral to length and bend over ends to retain leaves
Inventor: FABRIG PAUL
IPC: B42B5/12
Filed: 1976-12-07
Abstract: Three pads of loose leaves which are to be bound, are placed side by side in pockets in a rotating drum. The pads pass under tools which pierce holes along the edges of the sheets and then wind in one continuous spiral of wire (5) in all three pads (3). The pads (3) then pass under two cutting tools (13) which cut the wire of the spiral at the two points (15) where the separate pads about against each. The blades of the cutting tools overlap each other and after cutting the wire bend the cut ends inside the coil of the spiral so that the spiral cannot be detached from the pad.

Title: Winding tube body for yarns, threads - has elastically displaceable collar easily manipulated for clamping free yarn end
IPC: B65H75/28
Filed: 1977-01-24
Abstract: A winding tube for different types of textile yarns, wire thrreads and similar articles, has an annular groove on its periphery to receive the end of the thread. One side of the groove is delimited by a section which can be displaced axially. This is attached to the body of the tube and can close the groove towards the outside, to form a slit in which the thread is clamped. This section is annular and conical and can be set, by displacing it axially across a dead point, in a clamping position close to the opposite side of the groove or in an open position away from it. The body of the winding tube and the displaceable annular section are made in a single piece, esp., of thermoplastic material. The tube is very easily produced and holds the yarn securely without excessive press. When opened, the groove remains open without any outside effort being necessary.

Title: Dead space reduced in lower sections of fixed bed systems - having gas bubble blown in to reduce liquid hold up below bed support grid
Inventor: HOENIGSCHMID-GROSSICH RUEDIGER
IPC: B01J47/022
Filed: 1977-04-28
Abstract: Dead space in the lower parts of fixed bed systems for chemical or physical exchange, separation or adsorption processes is reduced by injecting gas below the bed before or during the process to form a gas bubble the size of which can be controlled. This is achieved by a level detector for the liquid in the lower section of the vessel. After the exchange operation, the bubble can be expressed by filling the base with liquid. It is removed via pipes mounted immediately below the bed support. An additional liquid inlet is located below the bed, and can be in the gas inlet line. Used with chemical or physical exchange, transfer or adsorption processes using fixed beds esp. water systems. The presence of dead space below the bed can lead to backmixing and contamination, of the trated liquid stream. The method described reduces this simply without the need for additional material in the vessel.

Title: Electrically cooled nuclear power plant - by using portion of electrical output rendering siting independent of rivers
Inventor: MUELLER HERMANN PAUL
IPC: G21C15/00
Filed: 1977-05-03
Abstract: A method of cooling a nuclear power plant consists of using electric cooling of the type used in refrigeration instead of conventional cooling using flowing river water. The power plant can thus be located in remote, desert or uninhabitated areas away from rivers, or placed below ground in mines and shafts or in remote mountainous regions. Power plant can be sepd. from centres of population, and in remote regions away from earthquakes and possible sabotage.

Title: Hydraulic brake system for vehicle with trailer - has switching valve in brake pipe between solenoid valve plug and hydraulic coupling to advance action of trailer brakes
Inventor: REITZ WERNER
IPC: B60T13/12
Filed: 1977-06-11
Abstract: The brake system produces an advance action of the brakes on the trailer. When the brake system is in the released position, but with ignition switch (31) in the ON position magnet (33) is energized and solenoid valve plug (53) is pushed into a forward position. Communication between connections (21, 26) is established, and brake cylinder (27) unloads the brake piping (12) via solenoid valve (13) and brake valve (17). If brake pedal is operated, switch (29) brakes the circuit (34) to the magnet (33), even before a brake pressure for the towing vehicle can build up in the brake valve (17). Magnet (33) is de-energized and spring (44) pushes the control element (53) towards the magnet (33). Fluid flows from reservoir (24) to trailer brake cylinder (27) and the brake is operated.

Title: Expanding shell mine strata-bolt - has wedges both sides of head held by ring and splayed by spring, to key into hole
Inventor: ROEHSLER HERMANN
IPC: E21D21/00
Filed: 1977-09-13
Abstract: The expanding shell strata bolt for mines, potash mining or tunnels comprises a wedge threaded onto the bolt shaft and and fitted both sides with wedges (c) held together by a locking ring (a). The wedges are splayed out by a steel spring (e) between the nut (f) and the wedges, when the bolt is inserted in the hole. Preferably the two wedges should be laterally offset at the ring to form a detent when the head (b) is drawn through between the wedges, thus preventing the head from running back. The ribbing on the wedges should point upwards so as not to break out the walls of the insertion hole and at the same time gain a firmer hold or keying into this as installed.

Title: Quality meter for frequency of telephone exchange faults - with quotient of events occurring put into counter used for correction of permissible number of faults
Inventor: DOTZAUER EWALD
IPC: H04M3/10
Filed: 1977-09-26
Abstract: The faults are counted by the sequential control method, in which specified switching processes are carried out when a limig of fault reports is reached during a continuously counted number of events. The counter is then reset to zero, resetting also the second counter which counts the faulty events. A common event counter (BZ) is allocated to all supervised units (F1-Fn). Each unit (F1-Fn) is connected to a fault counter (FZ1-FZn). The event counter (BZ) is connected to all fault counters (FZ1-FZn) by a common wire (a) through which they are reset. A quotient is formed from the number of events in a unit of time and the number counted by the counter (BZ). It is used to correct the limit of faults before an alarm is initiated.

Title: Jacquard warp knitting machine dispensing with pattern creel - uses section warp beams and tensionless buffer stores
Inventor: KOHL KARL
IPC: D04B23/22
Filed: 1977-12-24
Abstract: In a warp knitting machine with a Jacquard attachment, between the section beams on which the Jacquard threads are wound, and the thread brakes in front of the stitch formation point, a buffer store is provided for the jacquard threads in which they are held without tension. There is a thread brake for each thread. The let-off speed of the section beams is infinitely variable. The beams are driven at a speed corresp. to the greatest consumption of yarn at the stitch formation point. Used to eliminate the tedious work of changing the spools in a creel and make it possible to draw the threads for the pattern from a section warp beam without any difference of tension at the stitch formation point. This is partic. advantageous for short runs since the required length of yarn can be warped, and the beams easily exchanged.
