Title: Therapeutic mattress for patients - has main elastic body with many bores running through its thickness with e.g. foam in-fillings to produce desired pattern of softer areas
Inventor: KUEHNEGGER WALTER PROF DR
IPC: A47C27/18
Filed: 1989-11-08
Abstract: An orthosis, on which a human being lies, is made of elastic material such as foam rubber or other foam, it resembles a mattress and contains a bore running over its area and holding an inserted filling.  It has a series of adjacent bores contg.  fillings of various elasticities, its surfaces (on which a person lies) has a pattern of places of different resistance to the person on it. An oblong mattress type of prod. has a series of bores (2-10) at regular and short intervals running across its width to form a uniform pattern.  These bores are at the centre of the thickness but can be arranged differently if required.  They can also be open to the underside (as 30).  The bores can be filled in different ways. The fillings are rubber or other foam with a different hardness from that of the main body (1).  The filling in any one bore can only be partial or even absent, to provide a lQrn Of SOf rQg. ADVANTAGE - The prod. allows a wide range of theropeutic effects to be obtd. on the person resting on it.  This is achieved by the varying deg. to which the patient sinks on it, and the pattern of the variation is obtd. by the fillings pattern in the bores.

Title: Web shrinkage of strength measurement - uses equidistant parallel and lateral marks for measurement after process station to show distortion
Inventor: WOLDENBERG RICHARD VAN DEN
IPC: D21F7/06
Filed: 1990-03-15
Abstract: To determine the degree of local lateral shrinkage or stretch in a web, such as of paper or cardboard, a number of marking strips or lines are applied to the web before it  enters a drying station or similar point in the mfg. process, at fixed intervals parallel to each other at right angles to the web edges. After passing through the processing stage, the gap between the marks is measured, across the web edges. Pref. the deviation between the marking lines is evaluated by a computer, such as a microprocessor or microcomputer. A sensor (5) to determine the marking pulses slides across the web edges over the web width, to pass the pulses to a computer to establish the marking intervals. The gaps between the markings can also be determined by light pulses or other energy pulses. The gaps between the markings, along the length of the marking lines or strips, and their differences across the web, are passed to the web lateral profile control. The pulses from the markings are produced by light reflection or the fluorescence of the marking material. ADVANTAGE - The technique gives monitoring of the paper behaviour when there are a number of changes in the type of paper being produced, and also when there are long runs such as of newsprint to determine the paper distortion in short time intervals.

Title: Maintaining constant solid to liq. ratio in moving sludge - by computer-controlled injection of corrective mixt. of same materials
Inventor: HARTMANN HELMUT DR
IPC: G05D11/13
Filed: 1991-01-07
Abstract: In maintaining a desired final solid/liq. ratio in a stream of material which is not free-flowing, is pasty and/or sticky and difficult to pump, deficiencies in a main stream are corrected by adding a second stream. Both vol. and mass of the main stream, esp. of clarified sewage sludge are measured. The second stream contains a higher proportion of solids, either known in advance or readily measured, with the actual nature of the solids, the same for both streams. The final ratio in the emerging combined flow is applied to a controller acting on the second stream supply to produce the desired value. The second stream derives from a stored supply, or is recovered from a correctly balanced combined flow. ADVANTAGE - Avoids need for difficult continuous measurements of solids and moisture in the initial flow.
Patent DE-4104017-A1 (DE)
Inventor: BAAS DIETER
IPC: G11B7/095
Filed: 1991-02-09
Abstract: When data is being read off a optical disc, the light beam can lose the data track if it encounters a dirty or damaged spot on the disc. A tracking circuit steers it back on to the correct track some distance after passing the dirty or damaged spot. In order that the light beam (L) is steered back on to the correct track (B) as soon as possible after passing a dirty spot (SK), the invention calls first for the address of the point (1) at which the light beam (L) leaves the track (B) to be stored. From the control signal necessary to bring the light beam back on to the correct track, a first modified control signal is then calculated and also stored. When, during subsequent plays, the light beam (L) comes to the point (1) on the disc, now stored in the memory, the first modified control signal is fed to the tracking circuit. In order to produce an optimum modified control signal, the light beam (L) is taken several times past the point (1) stored in the memory, and each time a new modified control signal is calculated and stored. The invention is of use in CD players, video disc players, DRAW disc players and magneto-optical recording and replaying devices.

The height of the container is selected with the ergonomics of loading and unloading in mind, and the container has running boards (6) on one or both sides to facilitate loading. The dimension of the cooled chamber are chosen to suit the dimensions of the usual fruit or vegetable boxes or trays (7). USE/ADVANTAGE - Used in the harvesting of fruit or vegetables, and especially strawberries. Avoids rapid loss of quality between the moment of harvesting and the marketing of the fruit or vegetables, or storage in a cold store.

Title: Surface preparation rig for flat workpieces e.g. wooden veneer - has slider supports for grinding belt, individually adjustable via servo cylinders
Inventor: STEFANI GIORGIO
IPC: B24B21/10
Filed: 1991-05-23
Abstract: The surface is prepared by a moving grinding belt pressed onto the surface by a number of slider shoes (11) on a support beam. Each slider is mounted on a servo cylinder (7) whose operating pressure is regulated by a processor control to ensure correct pressure for the belt, and to reduce the pressure at the edges of the workpiece. This protects veneer layers from edge damage. Each cylinder is controlled by two solenoid valves (13,14) linked to high and low pressures. Each valve is adjustable (18,19) and the contour of the surface is monitored by wheels on the leading edge of the support beam. ADVANTAGE- Processor control, less risk of edge damage, processes delicate veneer layers.
