Title: Process for grinding and lapping accurate balls - involves machining holes in fixed lapping plate to interrupt tracks and vary ball rolling axis
Inventor: WERNER GUENTHER
IPC: B24B11/06
Filed: 1990-03-12
Abstract: During grinding or lapping balls roll along the opposed tracks (5) of fixed (1) and rotating (2) lapping plates. In the conventional process the balls must be passed through the plates a number of times to ensure that the rolling axis is varied. In the invention the rolling axis of the balls is varied by machining blind holes (11) breaking into the sides of adjacent tracks. The discontinuities of the tracks disturb the equilibrium of the ball and cause a sudden change in its axis of rotation at each encounter. A pattern of holes is introduced into the working face of the fixed lapping plate. ADVANTAGE - Simple, low-cost method of varying rolling axis of balls. Better quality, esp. in respect of form deviations.

Title: Producing stable encapsulated components - by applying thermosetting resin, then heating to above glass transition temperature and cooling abruptly
Inventor: BAYER HEINER DR RER NAT
IPC: B29C71/02
Filed: 1990-05-23
Abstract: Matrix of reactive resin with little or no stresses is produced, partic. for covering or encapsulating sensitive electrical or electronic components, by applying the resin (to suit the resin and application concerned) to or over the component and curing; raising the prod. to a suitable temp. to relieve stresses, where this temp. is above Tg of the resin matrix; sustaining a holding phase; and finally cooling it abruptly until an outer skin of the matrix reaches a temp. below its Tg. The rapid cooling stage first produces a skin with glass-like properties and hence a high modulus of elasticity. Thermal contraction is uniform but otherwise virtually no deformation occurs. Prod. interior remains in its rubbery phase and further cooling cannot cause further deformation but, instead, is more likely to be frozen tension in the skin. Inside this skin there is scope for further thermal movements of the molecular chains in the resin. This is important when the prod. is subjected to varying environmental temps. etc. Pref. resin whose Tg is higher than the max. temp. in service is used. Process is partic. useful where the resin used has a low thermal conductivity and where it is accordingly liable to suffer greater stresses. ADVANTAGE - Procedure is a good method of minimising residual stresses in the prod. Process is versatile and is suitable for a variety of resins and applications.

Title: Joining together ends of flexible belt - making two transverse grooves and matching lips at each end so that they fit together to produce strong joint which can be released by hand
Inventor: SCHILLINGER HARALD
IPC: F16G3/10
Filed: 1990-07-28
Abstract: The ends of a belt are bonded together by a method which uses a thin flexible high tensile strength material with a coupling part and a smooth part. The smooth part has the same width as the belt and the coupling part has at least two parallel grooves across the width; each groove has a lip on the side further from the smooth part; each lip has one part parallel to the smooth part and extending towards it. A second coupling is identical to that above, and the system has a device to connect the first or second to the corresp. ends of the belt. In the process the first coupling is permanently bonded to one end of the belt with the grooves and lips concerned running across the width; the grooves are then open towards one face of the belt; the second coupling is connected to a second section of the belt in similar manner with the grooves open to the second smooth face of the belt and opposite to the first smooth face. When the ends of the belt are brought together the grooves and lips match together so as to produce an endless belt; in this system the lips of the one coupling fit into the grooves of the other, so that the joints between belt and coupling withstand stresses but can be released by hand. Pref. materials for the coupling are vinyl or polyester elastomers. ADVANTAGE - The joining device is simple and cheap. The ends of the belt are joined easily and quickly. The ends are easy to separate again and they can be repeatedly joined/released. The joins have (partic.) high tensile strength and good wear properties. The thickness at the join is minimal and can even be the same as that of the belt itself so that it passes over pulleys, etc. without difficulty.

Patent DE-4129628-A1 (DE)
Inventor: SURAUER MICHAEL DIPL ING
IPC: B64G1/24
Filed: 1991-09-06
Abstract: A process is disclosed for controlling the attitude of a three-axis stabilized, spinning spacecraft, in order to maintain the spinning direction in inertial space and to limit the nutation amplitude. For that purpose, the deviation of the spinning direction from the set orientation, as well as the nutation amplitude, are constantly checked for exceeding predetermined set values (+/- d PHI , dN) by separate dead zone control elements. However regulating steps for reducing nutation may also be triggered when the spinning direction is within predetermined admissible limits. A corresponding attitude control device has at least one attitude sensor for measuring the angular deviation with respect to at least one of both lateral axes, and actuators for generating torques. From the angular deviation signals are derived two signal fractions that represent on the one hand the orbital displacement ( PHI 0) and on the other hand the nutational displacement ( PHI N) of the spacecraft. The first signal fraction ( PHI 0) runs in a first signal path with a first dead zone (204), the second signal fraction ( PHI N) runs in a second signal path to form a signal for the nutation amplitude (AN) and a signal for the nutation angle ( beta N). A common nutation regulator (205) for determining the moment when controlling torques are triggered is connected after both signal paths. The nutation regulator also receives the output signal of a second dead zone control element (209) which receives at its input the signal AN.

Title: Self-treatment of non-infectious, and non-hereditary illnesses e.g. Alzheimer's disease etc. - by increasing hydrogen content directly and slightly increasing indole and cortisone content by using high protein alkali diet e.g. including egg white, lean poultry etc.
IPC: A61K35/20
Filed: 1991-11-22
Abstract: To treat illnesses and conditions, the hydrogen content is raised directly and the indol and cortisone content raised only slightly indirectly according to the vascular condition and the illness-induced changes. This through infusion of hydrogen into the suction side of the heart, artificial respiration or inhalation of a non-inflammable, nucleide-free mixt. of hydrogen and air. The hydrogen is obtd. from pressure tanks and the use of hydrogen produced from battery chargers using mains current or solar energy where steam ignition is excluded. And/or the hydrogen, indol and cortisone content is controlled directly by enrichment of a high protein alkali diet contg. fibrin and tryptophan but low in carbohydrates and salt and fat, such as egg white, lean poultry and mutton, lean fish, low-fat dairy prods., skimmed milk, vegetables low in carbohydrates, and very limited quantities of acid fruit juice or organic acids. Pref. for the treatment of infectious illness, through viruses and/or bacteria, except for putrefactive conditions, the hydrogen and cortisone content is reduced, and the indol content sharply raised through an extremely acid diet rich in carbohydrates, but low in protein, fat and salt, such as acid fruit juices or organic acids, sugar with max. one egg white/day by enrichment of medication contg. indol. USE/ADVANTAGE - Method can be used for self-treatment of conditions such as Bechterew's reflex, Alzheimer's disease and various infections, and in the construction and operation of hydrogen-air inhalation rooms and appts., and increased usage of egg white, ground feathers, organic acids and indol derivatives.

Title: Piezoelectric module consisting of laminated monolith - has improved reliability due to sputtered film and metal foil outer electrodes and moisture resistant layer inside dielectric capping layers
Inventor: INOUE JIRO
IPC: H01L41/083
Filed: 1992-01-24
Abstract: The laminated, piezoelectric module, consisting of a stack of piezoelectric layers (2) contained between 2 inner electrodes (1) and glued together, are protected at each end by a dielectric layer (3). The modules feature thin film first electrode layers (4), formed by sputtering, connected to one of the electrodes of each piezoelectric sub unit. Thin metal tape (12) is pref. attached to each of the electrodes (4) by conductive adhesive. Connections are made to the outside circuit with metal wires (5) attached to the metal tape electrodes (12). Several stacks can be aligned to each other and attached using metal tape electrodes extending the entire length or just bridging the gaps formed by the dielectric layers at the end of each unit. The dielectric layers (3) pref. consist of at least 2 layers (13) which are laminated together using a moisture resistant glue. If several units are stacked together the inner dielectric layers pref. are thinner than those on the outside of the large stack. USE/ADVANTAGE - The construction gives much improved reliability of connection between the inner electrodes (1) and the outer electrodes (4). The metal tape contact ensures that the occurrence of cracks in the first electrode layer (4) does not cause degradation of the device performance, and they provide a secure attachment for the connecting wires (5), reducing the number of solder joints required compared with standard modules. The use of a moisture proof glue in the dielectric layers reduces the moisture sensitivity and increases the reliability. By reducing the thickness of inner dielectric layers in multiple stacks improves the module's performance by reducing the inactive part. The modules are used in print heads or as positioning devices.
