Title: Liq-liq extraction in pulsed sieve-plate columns - having in excess of one metre
Inventor: MUELLER ECKART DR
IPC: B01D11/04
Filed: 1975-01-22
Abstract: In a process for continuous liq.-liq. extraction in pulsed sieve-plate columns, the energy required to pulse the liqs. is introduced to each plate separately in columns having dias. greater than 1 metre. It is unnecessary to design the column to withstand the forces imposed by the entire contents of the column (several tonnes) in pulsation. A high mass-transfer rate is achieved which gives an increased column efficiency.

Title: Wall plug with hollow screw - has outer seal and radial ducts for introduction of adhesive
Inventor: SCHOLT EGON
IPC: F16B35/04
Filed: 1975-04-11
Abstract: The fastener is for attaching objects to walls or ceilings, and involves the use of a plugged hole (2). the diameter. The zone surrounding the hole (2) in the wall (1) is of heterogeneous material. The fastener (3) consists of a plug (5) and a screw (6) inside the plug. The threads of the screw cut into the plug bore, providing a secure attachment.

Title: Vehicle drum brake with internal brake shoes - has self adjusting lever assembly to compensate for brake wear
Inventor: DAU WOLFRAM ING GRAD
IPC: F16D65/54
Filed: 1975-04-24
Abstract: A wheel drum brake has internal brake shoes which are hinged at one end and in contact with the brake operating cylinder at the other end. An adjuster rod (1) is attached to the free brake shoe end so that it receives axial motion when the brake is applied. A clamp ring (5) together with two hinged levers (2) and a compression spring (6) form also part of the brake gap adjuster assembly. Wear on the friction pads is compensated by advancing the rod (1) through the clamp ring (5) which normally produces a non return function. When the brake gap is to small due to heat expansion of the brake drum (17), the hinged lever (4) loses its locking action on the clamp ring (5), thus the rod (1) is free to return to its original position.

These brackets are mounted at least at every second ceiling slab instead of the angular corner cutout. Rapid construction is possible, using a min. number of different components, and with only a few columns, none of which protrude beyond the wall surfaces.

Title: Extractor for sheet at stack bottom - has sheet bent along line positioned to suit inherent sheet buckling stiffness
Inventor: SCHUBERT BERNHARD
IPC: B65H3/50
Filed: 1975-06-20
Abstract: The system extracts the lowermost sheet from a stack, and is particularly for packet blanks used in the tobacco industry. The sheet is gripped on one or both sides and bent clear before removal. The sheet (4) is gripped and bent along a line (9) whose maximum distance from one of the sheet edges is such, taking into account the inherents stiffness of the sheet, that this stiffness is overcome, while the stiffness of the sheet above is sufficient to hold it straight. Where the sections of packing material have to be provided with a pre-formed fold line, the bend line can be arranged to coincided with this line.

Title: Square fuel element casing dimensionally checked - with quick reading sensors mounted in longitudinally sliding reference frame
Inventor: FUNKE HEINZ
IPC: G01B21/30
Filed: 1975-07-23
Abstract: The device used comprises one or more vertical arms carrying sensors oriented in a cross-sectional plane of the fuel element casing. These vertical arms can be moved longitudinally, parallel to the ideal side faces of the casing in steps, so that a succession of cross-sections can be measured. There are three sensors on each side of the casing, one at the mid-height and the other two located at points just at the corner radii. Used for checking fuel element casings e.g. of 3-5.5m length, where high accuracy in cross-section dimensions, e.g. of plus-or-minus 0.12 mm is required. Rapid surveying of the casings is possible with this device.

Title: Collector for solar radiation energy - has glass cover and absorber rigidly connected inside non rigid frame
Inventor: ULLI ERNST DIPL ING
IPC: F24S10/50
Filed: 1975-10-07
Abstract: The collector has an outer glass cover (2) and an inner glass sheet (2') with a thermally insulating gap (a) between them. The energy absorber (6) is below the inner glass sheet with a second thermally insulating gap (b) between them. The two glass sheets and the absorber are linked round their edges by side spacer pieces (7) which seal the air gaps and hold the glass sheets and absorber together in a rigid assembly. This assembly is placed inside a light sheet casing (3) which is not rigid. The sides and base of the outer casing (3) are lined with insulating material (8). Because the inner assembly is rigid the outer case need not be and can therefore be made lighter and cheaper.

Title: Scissors with replaceable and detachable cutting blades - has blade levers of different material from blade and has blade guiding pivot pin
IPC: B26B13/04
Filed: 1975-10-09
Abstract: The scissors have two pivoted scissor halves. The scissor cutting blades are held on backing levers made from steel, nonferrous metals, timber or plastics. The cutting blades can be replaced. The screw type pivot ensures good cutting contact between blades and the cutting blades are not loaded on return movement. The scissor support levers (1, 2) have profiled seats for cutting blades. These cutting blades may have two cutting edges so that they can be turned round. The cutting blades (3) consist of special steel and their cutting edges are ground hollow or straight. The screw type pivot (4) produces an angle such that on cutting the cutting edges contact so that the cut formed has no burr.

Title: Noise suppressor for radio receiver - has gate in LF channel controlled by coincidence of two selective detectors
Inventor: HANSEN JENS DIPL ING
IPC: H03G3/34
Filed: 1975-10-10
Abstract: The radio receiver noise suppressor has a gate in the receiver LF channel that opens when a noise burst is detected. The LF signal obtained from the AM demodulator (2) is applied to two selective detectors (5, 6). The outputs of the detectors are connected via an AND-gate (8) to the gating input of the gate (3). The gate receives a blocking pulse when the detectors respond together to the frequency spectrum of a noise burst. The detectors respond to two different frequencies, one of which lies in the receiver's upper frequency band.

Title: Continuous dry cleaning and distribution of clothes - without removal from hangers, with assembly line as in steaming tunnel
Inventor: SCHWOPE HANS
IPC: D06F95/00
Filed: 1976-02-19
Abstract: Continuous dry cleaning and distribution system for clothes is operated by hanging the article on a hanger on acceptance, and cleaning, finishing and returning it to the place of acceptance while still on the hanger. The articles of clothing are not turned over in drums, but while hanging on the hangers cleaned continuously on a conveyor belt, as in steaming tunnels which are already in use. Creasing of the clothes during storage and transport and centrifuging is avoided, the time-consuming step of hanging the clothes up is eliminated, and the clothes do not need to be handled after cleaning. The clothes can thus be dry cleaned at lower cost due to automation, and with less environmental pollution.
