Patent DE-3723463-A1 (DE)
Title: Peristaltic positive-displacement pump for liquids or slurry mixtures, with pneumatic or hydraulic drive
Inventor: NAGEL KARL
IPC: F04B43/10
Filed: 1987-07-16
Abstract: In a conveying line (pipe or hose) filled with a pumpable material to be conveyed, this material is displaced by another substance (e.g. air) with a slight excess pressure. Both substances are separated by an impermeable membrane (displacement cell). The direction is determined by having the conveying line blocked in the undesired direction during displacement by valves or by displacement cells filled with the displacing medium. By connecting these displacement cells in series, a peristaltic pump consisting of individual, physically independent sections is created over the entire conveying length. The displacement cells operate synchronously, periodically, and in groups, depending on the material being pumped and the design. The conveying system can be manufactured without valves or seals so that the material being pumped only comes in contact with the material of the conveying line. It can be used for delivery heads and distances of unlimited size at low operating pressures.

Patent DE-3726613-A1 (DE)
Inventor: HELLKUHL LUDGER DIPL ING
IPC: D06F37/06
Filed: 1987-08-11
Abstract: In washing machines, increasingly higher spinning speeds are required, with the result that the drum (1) together with the drum ribs (3) is exposed to especially high loads. So that the drum rib (1) of the washing-machine drum does not experience deformation even at higher spinning speeds, it is formed from a novel profile consisting of a U-shaped cap (8) and of rib webs (9) adjoining this in a V-shaped manner. Furthermore, it is provided in the region of its bottom edges with a bead (7), in order to ensure a stable fastening and compensate dimensional and production tolerances in the region of contact with the drum casing (2). The drum is suitable for all washing machines with a rotatable drum. <IMAGE>

Title: Waste collector
Inventor: NOSS KARL AUGUST
IPC: B65F1/14
Filed: 1987-09-10
Abstract: A waste collector (1) for a cupboard having a cupboard body (2) and a door (3) which closes the cupboard body and is articulated in a pivotable manner on a side wall (4) of the cupboard body (2) has at least one waste container (5), is articulated on the side wall (4) via an upper and/or a lower mounting (8, 9) in order to be pivotable about a substantially vertical pivot axis. The waste container (5) has an entraining edge (12) facing the inside of the door (3). Entraining elements (13, 14), which can be brought into engagement with one another, are provided both on the entraining edge (12) and on the inside of the door (3). By pivoting the door (3) out of its closed position into an open position which is offset relative to the closed position, preferably by about 90@, the waste container (5) is pivotable via the entraining elements (13, 14) out of an inward-pivoted position into an outward-pivoted position and vice versa. When this occurs, the entraining elements (13, 14) likewise change their relative position between an inward-pivoted position and an outward-pivoted position. The waste collector (1) is ideally suited for cupboards with doors (3) opening through more than 90@, if the door (3) can be pivoted beyond the open position and the entraining elements (13, 14) then disengage in a direction perpendicular to the plane of the door (3) when the outward pivoted position is passed and, preferably, the two entraining elements (13, 14) are designed as a snap-fit closure, and ...

Title: Orthodontic aid and method of producing it
Inventor: JECKEL NORBERT DR
IPC: A61C7/06
Filed: 1987-10-03
Abstract: The invention relates to an orthodontic aid having at least two tooth splints (6) designed as abutments and, where appropriate, an adjustable spacer (3) keeping the rows of teeth at a distance from one another. Such aids, in particular jaw expansion equipment, have hitherto been constructed specifically only for a particular therapeutic task and are more or less useless if the individual situation of the patient requires measures that go beyond or deviate from the task which the device is to fulfill. Therefore, it is an object to create an orthodontic aid which is designed such that it offers further therapeutic options beyond treatment of a simple trismus. The solution according to the invention resides in the fact that at least one tooth splint (6) is formed with at least one additional holder in each case (2) for connection of accessories. The basic element of the aid according to the invention is a jaw expansion apparatus (1) which has two tooth splints (6) and which forces the rows of teeth of the patient apart via an adjustable spacer (3) and permits chewing movements by means of a spring element (7). The jaw expansion apparatus (1) and, in particular, the tooth splints (6) with their additional tubes (2') are designed such that they permit addition of adjustment devices and such like accessories, which, for example ...

Patent DE-3812371-A1 (DE)
Title: Method for measuring the distribution of washing, especially in washing machines
Inventor: WIPPERFUERTH FRANZ-JOSEF ING G
IPC: D06F33/48
Filed: 1988-04-14
Abstract: In the case of a known device, in order to detect the distribution of washing and/or imbalance using a revolution counter which operates in a contact-free fashion by means of the distance measurement method and using a sensor which is fixedly mounted on the machine casing, the relative movement of the oscillating washing machine unit which is elastically suspended by means of shock absorbers is used as a basis. Disturbance factors which are associated with the device are not taken account of during measurement. The new method uses the energy which is directly converted in the oscillation path damping elements and/or the damping work which must be carried out to permit precise determination of the extent to which the washing is properly distributed and/or the imbalance. Some of the oscillating path damping elements are mechanical and operate using the friction principle. The frictional losses arising in them owing to poorly distributed washing cause increases in temperature which are used as a value to indicate the extent to which washing is properly distributed. A calculating method is used to decide whether the washing can be spin-dried or whether is must be redistributed. The method according to the invention is suitable for determining the extent to which washing is properly distributed, especially in washing machines.

Patent DE-3842823-A1 (DE)
Inventor: RUBACK WULF DR
IPC: C09K23/42
Filed: 1988-12-20
Abstract: The thickeners which are known and necessary for optimum applicational properties of aqueous surfactant formulations have disadvantages with respect to preparation and activity. Thus, for example, polyether esters can only be prepared under reduced pressure, elevated temperature and long reaction times. Electrolytes, for example, only have a thickening action when used in very high concentrations. The novel thickeners do not have these disadvantages. The use as thickeners of products of the reaction of a polyanhydride containing at least 2 anhydride functions with polyglycol ethers of the formula R-O(CHR1-CHR2-O)xH is proposed. These thickeners have a thickening action even when used in concentrations of from 1 to 5% and can be prepared under mild conditions. The use of products of the reaction of a polyanhydride with polyglycol ethers as thickeners in aqueous surfactant solutions.

Abstract: For continuously working different-length bars for frame elements of windows or the like, the bar elements are worked successively on one endface, recesses are milled into the long sides of these bar elements in the same position on a transverse conveyor, and the bar elements are subsequently worked on the second, opposite endface, without changing the spatial position, on a second conveying device downstream of the first conveying device and the transverse conveying device. A production facility of this type may be the loop of a production line. In addition, measures can be taken to bore the long sides of frame elements in this production facility.

IPC: B65G57/24
Filed: 1989-08-03
Abstract: When stacking up layers of boxes which have carrying handles or openings each layer consists of at least two rows in which the boxes have a different direction. A gripping device  (14) which can be moved horizontally and vertically relative to a pallet loading area is movable at right angles to the rows formed by the boxes.

The load pick-up means (18) are mounted so that each one part thereof is congruent with the box layer to be sized. This congruency can be achieved by horizontal displacement of the gripper (14). USE/ADVANTAGE - The stacker for layers of boxes has a lower number of load pick up means.
