Filed: 1993-12-03
Abstract: A friction clutch plate comprises a hub 6, a central disc-like component 36 and two outer such components 8, 9, together with coiled damping springs 13 which, with parallel friction devices 21, 22, provide the basic damping over the whole angle of relative rotation. Further damping, dependent upon angle, is provided in parallel through a control element 15 located radially inside springs 13 and between components 8 and 36. The element 15 has axially directed noses 18 which engage circumferentially larger openings 32 in component 8 and further noses 17 engaging openings 33 in component 36 with the interposition of circumferentially acting pre-loaded elastomeric springs 34. The springs 34 may alternatively lie in the component 8 (FIG 5) and the outer disc-like components may alternatively be secured to the hub (FIG 6). <IMAGE>

Title: Wellbore actuating tool with non-explosive power charge ignition
Inventor: ROSS RICHARD J
IPC: E21B23/06
Filed: 1993-10-15
Abstract: A wellbore tool is provided to perform work in a wellbore by converting a chemical pressure source into a force exerted over a distance. The wellbore tool includes a pressure chamber (106) sealed by a firing head (108) and containing a power charge (102) which includes a plurality of chemical components which are burned in a combustion reaction to generate gas. The combustion reaction of the power charge is initiated by a resistance heater (104) which directly initiates the combustion reaction by receiving electrical energy and generating heat. The combustion reaction generates gas within the pressure chamber (106), the gas having a pressure which pushes a pressure responsive member (18) into movement relative to the pressure chamber for providing a force over a distance to operate a downhole tool. <IMAGE>

Title: Spontaneous potential measurement in a wellbore
Inventor: TABANOU JACQUES R
IPC: G01V3/26
Filed: 1994-06-17
Abstract: A spontaneous potential (SP) sub is interconnected between two metallic housings 46, 48 of a wellbore apparatus and is lowered into a wellbore. A spontaneous potential (SP) of a earth formation traversed by the wellbore is measured by the SP sub, and a log is generated from the sub which is representative of the spontaneous potential of the formation. The SP sub includes a measurement electrode M, pairs of monitoring electrodes M1u, M2u, M1L, M2L placed on both sides of the measurement electrode, bucking electrode A1V, A1L placed on both sides of the monitoring electrodes, current driving circuitry connected to the bucking electrodes, and receiving circuitry connected to the monitoring and measurement electrodes. The current driving circuitry delivers a current of sufficient magnitude to each bucking electrode such that the voltage potential between the monitoring electrodes is approximately equal to zero. The current 54 from each bucking electrode is grounded via its own respective metallic housing and not via a surface oriented electrode. The receiving circuitry monitors the voltage between each of the monitoring electrode pairs and records the spontaneous potential at the measurement electrode at the time when the potential difference between the monitoring electrodes is zero. <IMAGE>

Title: Foot measuring apparatus
Inventor: TROMAN DAVID
IPC: A43D1/02
Filed: 1995-02-24
Abstract: A foot placed on the platform 18 is contacted by two driven pairs of opposed calipers, viz heel and toe calipers (26), 28 and width calipers 30, 32. The calipers are carried for relative movement by respective pairs of carriages (21), 23 and 31, 33 having a rolling engagement (25, 35) with corresponding longitudinal and transverse guideways 34, (36). Carriages 31, 33 and guideway (36) are carried by the toe carriage 23. Carriages of each pair have a motor driven rack and pinion connection 42, (40 or 49, 54) for effecting sequential foot contact operation of each pair of calipers. Such sequential operation is obtained by one caliper carriage (23), 33 of each pair being pre-loaded so that the other caliper carriage (21) or 31 moves first. Constant frictional pre-loading is effected by an adjustable shoe (56, 62) bearing against a rub strip 58 or 64. Potentiometers (41, 51) directly driven by motor pinions (40. 54) transmit the respective foot dimension to a processor for display of shoe size and width fitting.

Patent GB-2290278-A (GB)
Title: Coanda effect conveying systems
Inventor: COLEMAN JAMES DAVID
IPC: B65G53/58
Filed: 1995-06-15
Abstract: A fluid inlet unit (2, 3, 4, 5) is a block (9) which is located with one face forming part of the wall of a conveying duct. The face has a nozzle recess (11) to which pressure fluid is fed. By virtue of the Coanda effect, fluid from the recessed nozzle (11) passes out along the adjacent face. It is thus directed in the intended conveying direction. Thus conveying fluid is directed into the duct without the need for a nozzle projecting into it. The Coanda effect also leads to a sucking action. Thus a unit (9) located at the inlet of the duct can act to lift items into it from another conveyor (8). <IMAGE>

Patent GB-2319116-A (GB)
Title: Arc prevention circuit for a relay
Inventor: NISHIHARA THOMAS S
IPC: G01R25/00
Filed: 1997-11-03
Abstract: A device for delivering power to a load (4) includes means for controlling a switching relay(3). The switching relay (3) selectively couples a live line (1) of a power supply to the load (4). The load (4) is coupled to a neutral line (5) of the power supply. The device includes a sensor (6) for detecting whether an area is occupied. If the sensor (6) indicates that the area is occupied and the load is powered off, the device monitors the line voltage for a zero crossing. Upon detecting a zero crossing, an amount of time to a subsequent zero crossing is measured and stored. Then, the device waits the amount of time between zero crossings, less a delay time for closing the contacts of the relay, and initiates a closing of the contacts of the relay. Similarly, when the sensor (6) detects that the area has not been occupied for a predetermined amount of time and the load (4) is powered on, the line voltage is monitored for a zero crossing and a time to a subsequent zero crossing is measured and stored. Then, the device waits the amount of time between zero crossings, less a delay time for opening the contacts of the relay (3), and initiates an opening of the contacts of the relay (3) Accordingly, when the relay contacts actually close or open, the line voltage is at the ground level. Therefore, even if the load has a high in-rush current or high kick-back power, the relay contacts are not likely to be damaged.

Title: Liquid-cooled multi-cylinder i.c. engine
Inventor: BETSCH JOCHEN
IPC: F02F1/24
Filed: 1997-12-15
Abstract: In a liquid-cooled internal combustion engine with a cylinder head 2, through which the flow passes longitudinally, the cylinder-head screws 4 extend freely through the cooling-water spaces 6 and 12 in the cylinder crankcase 1 and the cylinder head 2 respectively, and thereby heat up more rapidly after starting. To improve the cooling of the cylinder head, the cooling-water space 12 in the cylinder head 2 is additionally connected to the cooling-water space 6 in the cylinder crankcase 1 by means of the orifices 24 in the cylinder-head gasket 3, through which orifices the cylinder-head screws 4 pass. The rigidity of the cylinder head, brought about conventionally by screw pipes, is achieved by means of longitudinal ribs (21, 22 and 23, fig.4) which extend from the cylinder-head bottom 8 to the cylinder-head top 9 and, at the same time, allow a controlled guidance of the cooling water out of the orifices 24.

Title: Roller key with soft key functionality for a telephone handset
Inventor: KRAFT CHRISTIAN
IPC: H04W88/02
Filed: 1997-12-22
Abstract: A telephone handset has a keypad 2 with a key 10 for navigating a cursor in a display 3, the key 10 being in the form of a depressable roller. Rolling of the roller moves the cursor up or down in the display, and pressing the roller effects a selection of an item pointed out by the cursor. The key 10 can be used as a "power soft key" or "hot key". Pressing the roller in the idle state causes a list of available operations to appear in the display 3. This list may be a user-defined list containing the favorite operations of the user and forms a power soft key menu. The power soft key functionality of the key 10 is only present in the idle mode of the hand set, while the key 10 is used for navigation and selection purposes in other modes. The roller 10 is coupled to an encoder connected to a processor which checks whether the signals from the encoder correspond to any one of a plurality of valid positions of the roller (Figs. 7-9).
