Title: Centrifuge for recovering volatile liqs. - having tangential outlets for liq. which is collected in circular channel
Inventor: PARAQUIN BURKARD DIPL ING
IPC: B04B11/02
Filed: 1975-02-25
Abstract: Centrifuge for recovery of light volatile liquids from mixtures with solids has the liquid outlets on the rotor directedly tangentially in the opposite direction to the station. The outlets are directed inwards towards the axis of rotation and downwards. They are directed into an annular covered collection channel. The airspace in this channel is kept relatively small and has only a small air throughput. For the recovery of volatile liquids and solvents esp. etherial oils and petrol solvents used for extracting vegetable materials. Conventional centrifuges induce a considerable air flows around the rotor or basket and the separated liquid becomes a series of fine droplets in this air before coalescing on the outer wall. With volatile liquids, this results in a major loss due to evaporation into the liq. stream. This centrifuge avoids this.

Title: Spindleless reeling of paper or pulp - esp. toilet paper and kitchen rolls, uninterruptedly changing from full to empty reel
Inventor: HEINEN GOTTFRIED
IPC: B65H19/22
Filed: 1975-05-17
Abstract: A centreless reeling machine for continuous bands of paper, pulp, etc. supports the reel during winding on river cylinders, the band running over a first cylinder driven in a fixed location in the frame. The first cylinder has a cut-off arrangement for the band, and faces a second cylinder pivoting under the control of a cam system. Between cylinders, there is a vertical passage the width of which is altered by the motion of cylinder, and above and below the passage, third and fourth cylinders are arranged, so that their positions relatively to cylinders, can be altered. The reel can be introduced into the space between cylinders, and the cutting arrangement together with an additional air nozzle guide the start of the band round the reel. During winding, the reel moves downwards until it rests on cylinder. When the band is cut, a transfer mechanism moves the finished reel forward and cylinders already in their original positions begin winding the new reel. Works at high speed without upsets. The next winding core is positioned at the point where the cutting off of the full reel takes place, so that the start of the bank is guided positively round the following core whilst the preceding reel is being taken off. There is no need to be brake the winding cylinders before cutting.

Title: Toupee attachment
Inventor: WLACH KUNO
IPC: A41G5/00
Filed: 1975-09-05
Abstract: A toupee or hair-piece attaching-method utilises liquid plastics for joining it to the natural hair. The toupee is easily fixed, esp. by the wearer, and does not irritate the skin of the head, since it is not bonded directly to the skin. By using a solvent, it can be removed every evening. If desired, it can be worn without removal for 4-7 days. To use, the head is washed and the toupee is cleaned. The liquid plastics is sprayed round the edge of the toupee. A few minutes later the toupee is put on. Alternatively, the liquid plastics is sprayed onto the natural hair and the toupee is put on a few mins. later.

Title: Pressure cooker with spring loaded cooking valve - has cam ring rotatable from outside valve to vary preloading of spring
Inventor: TANNER WILLY
IPC: A47J27/09
Filed: 1975-10-21
Abstract: The pressure setting valve fits into the lid of the pressure cooker and comprises a sleeve fitted with a piston held on to a seating by a coil spring located in the valve. The spring contacts the underface of a cam ring rotatable by a exterior lever and movable axially by a cam track in the valve to vary the spring load in accordance with the position of the lever. Marks on the valve head show the internal cooking pressure. As the pressure rises it overcomes the spring load and excess pressure is vented. An inner diaphragm controlled plunger smooths and stabilises the action.

Title: Fireproof cement asbestos sheets - are produced from slurry subjected to centrifugal action to produce uniform layer from which water has bee removed
Inventor: MCDONALD BRIDGET M A
IPC: D21F9/04
Filed: 1975-11-04

Title: Rolling mill stand drawout slide - with two crosspieces for alternate coupling to piston crossheads
Inventor: VOGTMANN LOTHAR
IPC: B21B31/10
Filed: 1975-12-04
Abstract: Rolling mill stand is equipped with a draw-out slide which can be extracted sideways on a track to change the rolls. The free end of the extraction power cylinder piston rod is fitted with a crosshead. The latter incorporates a coupling which can be connected to the crosspieces of the draw-out slide in turn. This enables the inexpensive power cylinder method to be retained even when the desired length of drawout motion exceeds the max. possible stroke of the cylinder. Work rolls can be exchanged by coupling the crosshead to the near side crosspiece, and back-up rolls by coupling it to the offside crosspiece.

Title: Fabric treatment fluid application - uses distributor tube and jet slit across width of spread fabric
Inventor: EBBINGHAUS RAINER
IPC: D06B3/32
Filed: 1976-02-20
Abstract: Appts. is claimed to control the fluid flow in washing machines, and similar equipment, where fabrics are spread out for passing through. A fluid distributor tube, or several tubes, are positioned in the treatment zone with a jet slit ranging over the fabric width. The fluid distributor tube can be rotated for adjustment on its longitudinal axis. Design allows the intensity of treatment to be related to the speed of the fabric passing through the treatment zone, i.e. such processes as washing, dyeing, bleaching, sizing or impregnating, for woven or knitted fabrics.

Title: Breaking up reinforced rubber scrap - preheated above room temp. with simultaneous comminution to separate reinforcing inlays
Inventor: SCHROETER MANFRED
IPC: B29B17/02
Filed: 1976-02-27
Abstract: Vulcanised rubber scrap, esp. old tyres, contg. textile or metallic reinforcing inlays, is broken up while preheated above room temp., pref. above 100 degrees C. The rubber is sepd. from adhering reinforcing inlays by simultaneous comminution. Complete sepn. of components is achieved economically. Heating weakens adhesion of reinforcing materials (e.g. adhesive strength of embedded steel wire at 100 degrees C is only 1/3 of its value at room temp.). The preheated ections can be broken up more cleanly and the screened steel wires are free from residual rubber. Throughput is increased and power requirement is reduced.

Abstract: The appliance is for the cutting and crimping of a thin tape esp. magnetic tape. It has a body (10) with a slot (12) in one longitudinal side, forming a track to accommodate the tape. A cap (40) acts elastically with the body to cut and crimp the tape. The longitudinal cap side covers the slot during cutting, and has two tongues, extending within the grooves in the body. The tongues are formed to force the tape into the correct position within the track before cutting. The cutter consists of a sleeve (14) within the body, open in the area of the slot, and of a punch (42) in the cap. The punch moves into the sleeve during cutting, and the cutting edge is positioned on the inner edge of the sleeve. For crimping, the body has an embossing surface (16) with grooves within the cutting area of the sleeve.
