Patent EP-0028736-A1 (EP)
Inventor: KRIEG JOHN J
IPC: F01L1/24
Filed: 1980-10-22
Abstract: A hydraulic tappet of the type having a one-way check valve (74) for valve gear of an internal combustion engine is provided which is especially suited for use in smaller displacement, higher r.p.m. engines, Tappets having conventional check valves in some instances experience unsatisfactory operation at higher engine speeds due to excessive internal pressure in the tappet which results in over extension of the tappet. The hydraulic tappet of the invention eliminates this problem and includes a movable plunger assembly (62) received in the tappet body (54). The plunger assembly defines an internal fluid reservoir (72) and, in combination with the tappet body, a fluid cavity (70). The one-way check valve (74) is located within the fluid cavity and comprises a spherical valve member (78) biased by a conical spring (84) into engagement with a valve seat (76) adjacent a fluid passageway connecting the fluid reservoir and the cavity. A retaining cage (79) surrounds the valve member and spring and limits the movement of the valve member away from the valve seat. In the maximum open position the conical biasing spring is compressed to a minimum height substantially  1  equivalent to its wire diameter, thereby permitting the ball to move away from the valve seat without obstruction from the I spring. An opening (88) in the retaining cage allows the valve member to extend partially therethrough to further increase the travel of the ball.

Abstract: A process for the manufacture of fibres from a polyamide entirely or substantially consisting of poly-p-phenylene terephthalamide, by spinning a spinning mass having a temperature of 20°-120°C and consisting of a mixture of concentrated sulphuric acid having a strength of at least 96% by weight and, calculated on the weight of the mixture, at least 15% of polyamide having an inherent viscosity of at least 2,5, the spinning mass being downwardly extruded into a coagulation bath from a spinneret whose efflux side is positioned in a gaseous inert medium and shortly above the liquid surface of the coagulation bath. The spinning mass is prepared by the successive steps of cooling the concentrated sulphuric acid to below its solidifying point, combining the sulphuric acid thus cooled and the polyamide, intermixing the two substances into a solid state mixture and heating the resulting solid state mixture to spinning temperature.

Title: Converter circuit for television signals
Inventor: VAN DE GRIJP ABRAM
IPC: H04B1/26
Filed: 1980-08-19
Abstract: A converter circuit (1) for RF signals for connection to the aerial input (3) of an RF superheterodyne receiver (2). In order to avoid a separate remote control of the converter circuit (1) use is made of the local oscillator radiation which is present at the aerial input of the connected RF-superheterodyne receiver (2) as an indication of the tuning frequency selected by the user with the tuning portion of the said RF superheterodyne receiver (2). The converter circuit (1) comprises a frequency search circuit (20) in which the frequency of the oscillator radiation is detected, an RF signal selector (11) which is controlled by the frequency search circuit (20) and by means of which the desired RF signal is selected from the RF signals applied to the converter circuit (1), furthermore comprising a modulator (18) which is also controlled by the frequency search circuit (20) and in which the selected RF signal is modulated on a carrier frequency which is determined by the tuning frequency and the intermediate frequency of the RF superheterodyne receiver (2).

Abstract: The invention relates to an exercising device primarily a baby-bouncer type device comprising a child support arrangement (19 to 33) and a support means (11 to 18 or 11, 12,13 and34to43) for resiliently suspending the child support arrangement (19 to 33) from a fixed location. The support means (11 to 18 or 11,12,13, and 34 to 43) includes a resilient member (16 and/or37) arranged to deform in compression to absorb loadings applied to the support means (11 to 18 or 11, 12,13 and34to43). Thus, contrary to prior art devices wherein the resilient support means comprise tension members, the device of the invention affords a support arrangement which, even with total collapse of the resilient member (16 and/or 37), maintains full and safe support for the child.

Abstract: In the process for the treatment of waste water for analytical techniques by sedimentation and filtration, the waste water is passed to a first sedimentation step (3). This process is repeated at least once, after which the waste water depleted in each case of solid water ingredients is passed to the next sedimentation step (8, 9). Following the last sedimentation step (9), the waste water depleted of solid water ingredients is allowed to pass through a belt filter device (13). There it can be removed as treated water for analytical purposes. After removal of the water, the treatment plant is emptied. After that, the treatment can start again. <IMAGE>

Patent EP-0053873-A1 (EP)
Title: Linear magnetic bearing
Inventor: STUDER PHILIP ALBERT
IPC: F16C32/04
Filed: 1981-10-22
Abstract: A linear magnetic bearing includes a stator member (16) stationary relative to x, y and z axes and having a longitudinal axis on the z axis as well as a member (15) longitudinally translatable relative to said axes. The translatable member (15) is controlled to have a longitudinal axis coincident with the z axis. Permanent magnet means (36 and 37) on one of the members positions the translatable member (15) in a plane defined by the x-y axes relative to the stationary member (16). The position of the translatable member (15) is sensed by sensors (41 and 42) relative to the stationary member (16) in the plane defined by the x-y axes. Electro-magnet means (38 and 39) on one member (23) responds to the sensor (41 and 42) to center the longitudinal axis of the translatable member (15) on the z axis. First low reluctance magnetic flux paths for the permanent magnet means (36 and 37) exist through both of the members and a radial air gap (32, 33, 34 and 35) between the members. Second low reluctance magnetic flux paths exist for the electro-magnet means through both of the members and a radial air gap (34 and 35) so no net force is applied to the translatable member in the direction of the z axis by either-the permanent magnet means or the electro-magnet means. The first and second low reluctance flux paths are arranged so that both the electro-magnets and permanent magnets share a common air gap but the electro-magnet fluxes do not pass through the high reluctance permanent magnets. One of the members includes two fixedly spaced elements (23 and 24) along the z axis. Each fixedly spaced element (23 and 24) has four radial pole faces (27, 28, 29 and 30) for the permanent magnet flux paths. At least two of the radial pole faces of each element provide x and/or y position control via the electro-magnet flux interaction with the permanent magnet flux in the common air gaps.
