Patent DE-3819544-A1 (DE)
Title: Grip stabilisers for rackets
Inventor: SCHULLAN MAXIMILIAN
IPC: A63B49/08
Filed: 1988-06-08
Abstract: In order to increase the holding power (grip) of the racket hand on the racket handle when the ball is struck, the stabiliser is attached in the lower region of the racket grip at the distance from the racket grip end necessary for the particular player. As a result of the grip channel, which extends obliquely over a plurality of grip surfaces and has concave and convex surfaces, the tensile and compressive forces of the index finger and thumb, which are particularly stressed in striking the ball, can be optimally converted by inserting or introducing them into the grip channel and the holding power of the racket hand can thus be increased.

Title: Electrically operated appliance for preparing infused beverages, in particular tea
Inventor: MATUSCHEK MANFRED
IPC: A47J31/057
Filed: 1988-06-30
Abstract: The invention relates to an electrically operated appliance for preparing infused beverages, in particular tea. These appliances are also known as tea-making machines. Such an appliance has a housing for accommodating switching and controlling devices and also a fresh-water receptacle with an assigned heating means. The heated water passes from the fresh-water receptacle via a rising pipe into a drawing receptacle, in which the tea to be brewed is situated. The outlet of the drawing receptacle lies above a collecting receptacle for the finished tea. This outlet is to be closed by a spring-loaded valve and to be opened by a timing element. In this case, a variable-position lever is arranged between the timing element and the valve. The timing element furthermore has a releasable blocking means. The blocking means cooperates directly with a movable part of the timing element. The blocking means can furthermore be transferred into its release position by a thermostatic switch, such as a bimetallic switch. Once the release position has been reached, the timing element can start to run. After expiry of the timing-element period, the valve of the outlet of the drawing receptacle is then opened and the finished tea can pass into the collecting receptacle situated therebelow. It is stored there, preferably using a heating means to keep it warm.

Title: Process for producing a raw material mixture for glass manufacture
Inventor: BOEBER REINHARD
IPC: C03B1/02
Filed: 1988-07-19
Abstract: To produce a raw material mixture for glass manufacture, one or more waste products are used which arise in powder form or are converted from a compact form into the powder form. The pulverulent waste products are suspended in water, introduced into a fluidised bed and combined with a nucleating shell, whose grain is larger than that of the waste product powder. The nucleating material can be a material belonging to the type of the waste products and, as such, can be suspended with them, or it can be an extraneous material which is sprinkled in uniform distribution from above into the atomised waste product suspension. If small materials of the same type and of an extraneous type are used in the same agglomeration process, these have the same grain size. Using the waste product powder, at least one further suitable component of the raw material mixture can be suspended and atomised.

Title: Compact construction of a Michelson interferometer for the measurement of changes in length and in refractive index
Inventor: JESTEL DIETER DIPL PHYS
IPC: G01B9/02
Filed: 1988-07-28
Abstract: In comparison with previously used classical interferometers, this invention is distinguished by its miniaturised, simple, compact design, which, furthermore, reduces the calibration effort, which is considerable in a conventionally constructed Michelson interferometer, for the alignment of the measuring mirror. The light is guided in single-mode waveguides which are produced by means of structured ion exchange in glass substrates or diffusion into crystals. The beam-splitter is realised optically integrated by means of a symmetrical coupler. Beam-splitter, reference arm and reference mirror lie protected in the substrate. The interferometer is thereby insensitive to vibrations and electromagnetic interference radiation. The invention can be applied anywhere where the physical quantity to be measured industrially effects an alteration of the optical path.

Title: Self-cleaning filter for liquids containing solids
Inventor: STARK HELMUT
IPC: B01D29/11
Filed: 1989-02-17
Abstract: According to the invention, a tubular filter material is used which, for protection against tearing, internally abuts a tubular metallic or synthetic cloth bag. The filter bag is fed via an upper filler port. At the bottom, it is closed by a shut-off element through which the filtrate residues can be discharged as required. The closed end of the filter is either freely suspended in the filtrate collection vessel and the filter bag must be removed for the emptying, or the end port, on which is situated the shut-off element, can alternatively be passed through the base of the collection vessel and filter residue can be removed externally. Gentle shaking of the filter can reinforce the self-cleaning of the filter. Self-cleaning takes place by the filter residues being flushed downwards and collecting there.

Patent DE-3906679-A1 (DE)
Title: Accelerometer
Inventor: EVANS KENNETH STEPHEN
IPC: G01P15/13
Filed: 1989-03-02
Abstract: An accelerometer is described which has a housing (10) which forms a chamber (11), a magnetisable flowing medium (17) inside the chamber (11), an electrically conductive, hollow cylindrical test mass (16) which is supported in the chamber (11) in such a way that it can be displaced along an axis of displacement from a zero position by an applied force, and a sensing device which contains electrodes (20, 21, 22) on the inner wall of the chamber (11) and determines a displacement of the test mass (16) along the axis of displacement and supplies an electric signal representing the applied force. The test mass (16) is essentially non-magnetic, and there are arranged outside the chamber (11) magnets (18, 19) which magnetise the magnetisable flowing medium (17), so that the test mass (16) is supported inside the chamber (11) by the flowing medium (17). Since, by contrast with previously known accelerometers, the test mass (16) itself need not be magnetic, no magnetic interaction occurs between the magnetised particles of the flowing medium (17) and the test mass (16), and the effective mass of the test mass (16) is therefore essentially not influenced by changes in the distribution of the particles. <IMAGE>

Title: Ski with an add-on device
Inventor: GRILL FRITZ
IPC: A63C9/00
Filed: 1989-03-16
Abstract: A ski is provided with an add-on device which is designed as a separate component relative to the ski binding. The add-on device has a contact surface for a region of the top (2) of the ski (4), situated between the ski tip and the ski binding, and a hollow body (10). The hollow body (10) possesses, in the region of the contact surface, a wall (22) in the form of a half-shell, which widens over its continuous surface away from a tip (16) which is at the front in the direction of movement of the ski (4) and, in the region of its open end surface (18), largely covers the front jaws of the ski binding. In the region of the contact surface, the add-on device rests with its lower edge (26) on the top (2) of the ski (4), leaving little or no gap. The width of the hollow body (10) is, at the most, equal to the width of the ski (4), so that the add-on device does not project beyond the cheeks of the ski. The add-on device substantially reduces the risk of injury, because the edges of the ski binding which can cause injury are largely masked, and also gives the ski an attractive appearance. <IMAGE>
