Title: Top dressed playing surface with resilient underpad
IPC: B32B5/24
Filed: 1979-10-01
Abstract: A playing surface for athletic games comprising a stable subsurface (2), a resilient underpad of specified character (4), a pile fabric resembling grass (6) and a sand top dressing (10). The inventive surface is particularly suited for use as a golf green which properly facilitates control of an approach shot and also provides a true putting surface. The playing surface simulates the feel and appearance of natural turf, but has a much greater durability and requires less maintenance. By appropriately varying the construction of the surface, it is possible to control its character to provide for a desired type of play.

Title: Circuit for controlling the grid potential of a pulsed X-ray tube
IPC: H05G1/50
Filed: 1980-10-27
Abstract: The output of drive circuit (Figure 1) is connected to the tube grid G by a long cable having a large capacitance Cc. Circuit 1 applies a continuous DC regulating voltage to a rail RL2 and circuit 2 periodically generates a blanking voltage on rail RL3. Rail RL2 is coupled to RL3 via a clamping diode Dc which is reversed biassed by the blanking voltage, so that the regulating voltage is overriden. In order to quickly discharge the large capacitance Cc to achieve a rapid transition from blanking voltage to regulating voltage, a discharge path is connected across the output, the path including a transistor T1. A control circuit 3 comprises a capacitor C2 which stores an actuating voltage VT produced when the blanking voltage is produced. When the blanking voltage is produced the junction of R1 and C1 is maintained at a high negative voltage and T1-is non conductive. During the transition from blanking to regulating, network R1, C1 switches on T1 and this controls the discharge of the cable capacitance. <IMAGE>

Title: Hydraulic energy absorber
IPC: F16F9/08
Filed: 1981-03-16
Abstract: Hydraulic absorber of the energy of a moving mass comprises a cylinder 1 separated into two working chambers 10, 12 by a piston 7, 8 connected to the moving mass; movement of the piston forces a liquid to pass from one working chamber to the other through a narrow passage wherein it is throttled, with conversion of mechanical energy into heat. The device is filled with liquid, and includes an auxiliary chamber 11 with elastic walls maintaining it under pressure. The auxiliary chamber communicates with at least one of the working chambers 10, 12 through a valve system 20, 22, 25 permitting free passage from the auxiliary chamber to the working chamber but allowing flow in the opposite direction only under the action of high pressure generated in the working chamber. The invention is applicable to dampers for oscillations of low amplitude, in particular for railway rolling stock. The auxiliary chamber with elastic wall may instead surround the working chambers. <IMAGE>

Title: Potentiometric electrode
IPC: G01N27/403
Filed: 1981-11-26
Abstract: A potentiometric electrode includes an enclosure 22 containing an internal electrolyte 26 which couples the sensing area (eg membrane 24) to a lead 28 of electrically conductive material such as a noble metal inert to the electrolyte; the electrolyte comprising a thermodynamically reversible redox couple having a large exchange current (>/= 10<-6> amp/cm<2>). Examples of such redox couples are:  2e<-> + I3<-> &rang& 3I<->  e<-> + Fe<3+> &rang& Fe<2+>  e<-> + Fe(CN)6<3-> &rang& Fe(CN)6<4->  2e<-> + Br2 &rang& 2Br<-> This construction substantially improving the response time of the electrode to changes in ambient temperature. For ion-sensitive electrodes with internal buffers, the redox couple can be selected so that its temperature coefficient ( DELTA E/ DELTA T) is the inverse of the temperature coefficient of the buffer, thereby rendering the electrode substantially temperature insensitive. <IMAGE>

Title: Torque transmitting body for traction drive transmissions and normal friction force developing method
IPC: F16H37/02
Filed: 1980-05-19
Abstract: A nutating traction drive in which external rolling surfaces on a one-piece bi-conical body (10) are retained against axially spaced internal ring surfaces (51, 52) at diameterically opposite points of contact by a mechanism acting between a body (18) which is rotatable on the axis of the ring surfaces or a first axis (24) and which carries the biconical body (10) on a second axis (30) inclined with respect to and intersecting the first axis at a point (S) of axes intersection located midway between the ring surfaces (51, 52) and points of contact. The mechanism includes a pivotal member (66) having a fulcrum point (78) eccentric from the first axis (24) or displaced from a plane containing both the first (24) and second (30) axes so that a torque reaction to rotation of the carrying body (18) by the biconical body (10) results in a force attempting to increase the angle between the first (24) and second (30) axes. A preloading device (82) acting to rock the pivot member (66) in one direction provides a preload bias of the rolling surfaces against each other whereas an unloading device (84) operating to swing the pivot member in the opposite direction results in a removal of normal friction force between the engaged rolling surfaces.

Title: Carburation balancing using piezo electric transducers
Inventor: DENNESS RICHARD
IPC: F02M19/01
Filed: 1984-11-30
Abstract: Piezo electric transducers are fitted into the induction manifolds of the engine at the same point that a vacuum gauge or manometer would be fitted producing a voltage proportional to the vacuum pulse applied by the engine. These voltages are then each connected by a twin screened cable to a pair of amplifiers, then rectified. Then each rectified output is buffered to give a D.C. signal that can be monitored, thus the engine's induction pulses can be monitored and the carburation can be adjusted to set the vacuum pulse levels the same within the induction manifolds.
