Title: Partitioning wall suspended on support rails - has motor actuating wall and ceiling elements
Inventor: KAPS KARL-HEINZ DR
IPC: E05F15/638
Filed: 1974-02-01
Abstract: The partitioning wall elements are each suspended from two supports which travel on guide rails. The vertical edges of the wall elements have seals at their contact edge. The horizontal edges have sealing strips for containing the floor or the ceiling of the room. The wall elements are arranged so that whole walls can be displaced laterally depending on the requirements for the room. The electric motor used for actuation reduces manual effort in adjusting the wall. Each wall element is independent of the other elements and has its own independent drive mechanism. The wall element is suspended from two trolleys and these are driven by the electric motor. This electric motor actuates the support trolley and it also actuates horizontal seals. The motor is mounted within the door panel and its drive shaft passes through the top of the wall element and it is geared to the trolley drive.
Patent DE-2405095-A1 (DE)
Title: Drainage floor or wall covering for swimming pools etc. - has hard-wearing fibrous surface with thermoplastic suction-head type spacers
Inventor: HOLST DIETER
IPC: E04F15/10
Filed: 1974-02-02
Abstract: The drainage floor covering comprises an upper water-permeable layer consisting of a woven or similar material with fibres which is separated from the floor by spacers. These spacers are in the form of suction heads which also provide a good non-slip support and consist of thermoplastics material which are applied individually in the viscous state to the underneath of the upper fibrous layer. These individual viscous drops of material are passed with the fibrous layer through a heat drying process where the height of the drops before heat action is at least 2 mm. The thermoplastics material is preferably thixotropic and contains an expanding agent which causes the spacers to have a porous structure on passing through the heat drying process.
Patent DE-2407751-A1 (DE)
Title: Fresh air heater and ventilator for car - heaving double flap to isolate heat exchanger inlet and outlet
Inventor: JOBST WOLFGANG
IPC: B60H1/00
Filed: 1974-02-18
Abstract: The fresh air heating ventilation system has a control flap which diverts all or part of the airstream over the heat exchanger and then mixes the warm and cold airstreams to generate the selected temp. input to the car interior. Such systems can suffer from heating even when the input to the heat exchanger is closed off, due to warm air being dragged out of the exit duct of the heat exchanger. The invention has a double flap, with one half of the flap controlling the input to the heat exchanger and the other half the output. The input and output ports are side-by-side so that the flap can close both together. No special control linkage is required and the leading edge of the input flap distributes the airstream from the blower.

Title: Foundation for ensuring draining of water - is water permeable for draining water on masonry into drainage system
Inventor: NAGL KURT KONRAD GUSTAV KARL
IPC: E02D27/01
Filed: 1974-07-12
Abstract: The water draining foundation is used for masonry walls, and can be a strip foundation or a foundation plate. The foundation can be made partly or wholly from a porous water permeable material to facilitate draining of water from the joint between the foundation and the vertical walls. The permeable foundation diverts the water into the drainage pipe. The porosity of the foundation is such that it has low adhesion and low capillary suction effect. This arrangement is capable of eliminating water which attempts to penetrate the gap between the foundation and the wall base. It is also capable of draining condensation water which is deposited within the building.

Title: Patterns for casting small batch quantities - made by building up a finished part with sprayed metal
Inventor: WINKEL MARTIN
IPC: B22C7/00
Filed: 1974-09-25
Abstract: A process for mfg. monolithic, i.e. one-piece, foundry patterns, uses a normal workpiece possessing the final dimensions onto which a layer of easily meltable metal is sprayed using a metal spraying pistol, the m.pt. of the metal coating being appreciably below the m.pt. of the workpiece, and the thickness of the coating matches the shrinkage allowance required or is only slightly more than this allowance. The pref. metal coating is Sn, Bi, white-metal or a similar alloy with low m.pt. and different coating thickness may be used to achieve desired dimensional changes and/or provide a machining allowance for polishing or grinding the pattern. Esp. used for the prevision casting of steel. When only very small prodn. quantities are involved, the cost of producing the batch by machining out of solid metal is prohibitive, nor can the cost of a pattern be justified. The invention uses a finished part to make a pattern.

Title: Photothermographic process with erasure of unwanted image - by heating exposed emulsion contg. halohydrocarbon andN-vinyl cpd.
Inventor: SANO REIJI
IPC: G03C5/56
Filed: 1974-10-31
Abstract: The photographic process employs a matl. coated with a photosensitive mixt. of discrete particles of a halohydrocarbon and an N-vinyl cpd. dispersed in a hydrophilic binder for erasing a first latent image, if it is not wished to develop this, and then for producing a second latent image on the same photographic matl. The matl. is (a) exposed selectivity with actinic light to produce a first latent image, (b) heated to 60-120 degrees C to erase this image, and (c) exposed selectivity with actinic light to produce a second latent image, exposure with actinic light being moderate, so that the latent image is not developed to a visible image by stage (b) alone. The cycle of stages (b) and nc) can be repeated at least once if the second latent image is also unwanted. In addn. to the possibility of erasing unwanted images, numerous images can be produced on different areas of the same matl.

Title: Stalk separator on combine harvester - is hinged to cutter and is flapped up or down by means of hand-operated spring-loaded bolt
Inventor: SCHNEIDER WALTER
IPC: A01D63/04
Filed: 1974-11-16
Abstract: The cutter has an intake roller, with cutter fingers and stalk separators (5) with inward-deflectors. The stalk separators are hinged to the cutter (3). When flapped out or in, they can be fixed in this position by means of a manually operated spring-loaded bolt. The height of the stalk separator can be moved on the shaft with the slot-guide of a bolt. A metal shield moves with it, but does not flap inwards. The stalk separator prevents the cut stalks from winding round the shaft.

Title: Photoelectric regulation of speed of tape winding spindle - involves photocell partially shadowed by tape coils to produce control signal
Inventor: THUN VOLKMAR
IPC: G11B15/46
Filed: 1974-12-28
Abstract: The apparatus has a lamp which shines through a lens to send a beam of light between the tape feed spool and the take up spool, parallel to the axes of the spools, and the light not cut off by the coils of tape falls onto a sensor which provies two inputs to an amplifier. The singe output of the amplifier is connected to a control device which regulates the speed of the motor which drives the spindle on the takeup spool. the torque produced by the motor is regulated according to the diameter of the coil of tape: the torque increases as the tape is wound up on the spool so as to keep the tension of the tape constant.

Title: Blood pressure gauge using vibrations for measurement - korotkoff sounds are picked up by microphone and transformed to vibrations
Inventor: NICOLAI WALTER
IPC: A61B5/022
Filed: 1975-01-07
Abstract: A manually operable sensor accessibly by the investigator is directly or indirectly set into characteristically differential movements i.e. vibrations as the acoustical accompanying phenomena occur (i.e. Korotkoff sounds) and the pressure valves are signalled to the investigator for systolic and diastolic measurements. Pref. the Korotkoff sounds are picked up directly or indirectly with a microphone (3) and amplified (9). The sensor (8) is an electromechanical transformer through which the Korotkoff sounds are fed over a vibrator (10) causing periodic vibrations corresponding to the systolic and diastolic pressure. The pump to inflate the pressure cuff can also serve as the sensor organ.
