Title: Clutch actuator which limits diaphragm spring deformation
Inventor: HUSSE ULRICH
IPC: F16D23/14
Filed: 1997-12-22
Abstract: A clutch actuator comprises a motor 33, operated by a foot pedal 54, which rotates gear-wheel 22, via gear 28, so that bearing 32 is rolled along withdrawal lever 36, pivoted at 41, towards and away form axis 50. When the bearing 32 is rolled away from the. axis 50 it engages control cam 38, thereby urging the latter tight against pressure element 8 by the force of diaphragm spring 17 acting through nose 43. The element 8 transmits the force, via rolling bearing 14, to pressure plate 10 so as to clamp friction linings 7 between the pressure plate 10 and counter pressure-plate 52 on flywheel 1. To disengage the clutch the motor 33 is reversed and the bearing 32, via wheel 22, is rolled along the lever 36 towards the axis 50. As soon as the bearing 32 passes the axis 41 the lever 36 is pivoted towards stop 42, in this position the nose 43 is lifted away form pressure element 8 and the force from the diaphragm spring 16 is transferred to the stop 42. Because the force of the diaphragm spring 16 is constant, eg when the clutch is engaged and disengaged, the deformation of the diaphragm spring 16 is not significantly altered. The gears 22, 28 may be replaced with, for example, a belt transmission and the actuator may have a wear compensating device (see figs 7 to 9). In another embodiment a lever element (112, fig 4) is force by diaphragm spring (116, fig 4)in the direction of a pressure plate (108, fig 4) by balls (138, fig 4) located in wedged shaped tracks (134, fig 4).

Title: Growth of group III nitride or group III-V nitride layers
Inventor: HEFFERNAN JONATHAN
IPC: H01S5/00
Filed: 1997-12-18
Abstract: In order to effect growth of a Group III nitride or Group III-IV nitride layer on a GaAs substrate 2, the layer 1, typically made of Al x Ga 1-x As, is grown by molecular beam epitaxy (MBE) whilst the substrate 2 is contained in a vacuum chamber and A1, Ga and As fluxes are supplied to the substrate 2 which is maintained at an elevated temperature of about 600‹C for example. The substrate 2 and layer 1 are then placed in a chamber (which may or may not be the same as the vacuum chamber within which MBE growth of the layer 1 has been effected) and are exposed to an ammonia gas atmosphere 4 so that the layer 1 is chemically converted to a Al x Ga 1-x N buffer layer. The substrate 2 and buffer layer 1 may then be used as a substrate for the subsequent growth of Group III nitride semiconductor materials and devices, thus improving the quality of subsequently grown nitride epitaxial layers. Alternatively, InAlAs or InGaAs layers maybe nitrided to form buffer layers.

Patent GB-2341156-A (GB)
Title: A component cooling arrangement
Inventor: RANSON MARTIN
IPC: B60K11/06
Filed: 1998-09-04
Abstract: Electrical components (1, 2) inherently generate heat energy when operational and thus with regard to hybrid or electrically propelled motor vehicles, such components (1, 2) can have a diminished operation efficiency and reduced service life expectancy. These electrical components (1, 2) are cooled by a trickle air flow created through existing evacuation means (4) necessary for servo mechanism powered braking systems, etc. Essentially, a vacuum is created within a manifold (10) to which vent inlets adjacent to electrical components (1, 2) are coupled. Thus, air is drawn through the vent inlets away from the components (1, 2) to cool them. Normally, pressure switches or valves (5, 6, 7) are incorporated within the arrangement in order to ensure that a sufficient vacuum is retained within the manifold (10) to ensure operability of the servo mechanism (3) associated with a mechanical actuation means.

Title: Microbial control process in food processing equipment using ozonation
Inventor: HEI ROBERT D
IPC: C02F1/78
Filed: 1996-12-04
Abstract: The invention relates to treatment of aqueous streams and aqueous systems with ozone. The aqueous stream comprises a closed loop system providing transport from a production locus to a processing locus for a variety of products. The aqueous stream can contain a challenge soil load and a microbial load. A treatment zone is defined through which the aqueous stream passes. The treatment zone is contacted with a sufficient concentration of ozone to substantially reduce the microbial population and to substantially reduce the number of microorganisms that can generate slime on the interior of the system. An amount of ozone is added to the aqueous stream in the treatment zone such that once the microbial populations are reduced to a safe level, the ozone concentration is also reduced to a level substantially safe for contact with operating personnel and product. Typically, such concentration is less than one part by weight of ozone per million parts by weight of aqueous system, preferably less than 0.5 parts by weight of ozone per million parts of aqueous system. The use of a treatment zone in an aqueous system segregates the ozone from release into areas frequented by operating personnel, sensitive materials or product.

Title: Apparatus for conveying solid material within a separator
Inventor: SINKER ALASTAIR BRENTON
IPC: B01D21/24
Filed: 1998-10-29
Abstract: In a separator, apparatus for conveying solid material comprises at least one eductor 60 located within the separating vessel 66, arranged to generate a localized solids jet flow. Hence turbulence within the separator is kept to a minimum. The eductor acts as a jet pump which uses some of the energy from a motive fluid entering a jet inlet 42, to entrain solids entering an inlet 40 in order to eject it from an outlet 44 at a higher pressure than that at which it entered. The motive fluid (from pipe 67, fig 6) may be sea water, water from an oil well, or hydrocarbon. The eductor(s) may be arranged along the bottom of the separator, and if there is a plurality they may be connected in series, or "daisy chained", so that the output of one eductor provides the input for the next in the chain. Transverse eductors (70, fig 6) may also be provided in order to fluidize the side wall region of the separator, and may be inclined. The axial eductor(s) transports the solids along the bottom of the separator in the direction of bulk flow, to the solids outlet. Furthermore, an outlet eductor 80 may be used to draw fluidized solids from the solids outlet 64, of which there may be more than one. The separator may alternatively have a vertical arrangement, and may be used to classify the various phases produced from an oil well.

Title: Motor rotation control for an optical disk player
Inventor: SHIM JAE-SEONG
IPC: H02P29/00
Filed: 1998-12-22
Abstract: A sensor (402, Figure 8) senses the rotational direction and rotational state (speed) of the motor (400) and a signal generator (404) generates a control signal from the sensed parameters for operating a motor controller (406) and hence the motor so that it rotates at the desired speed. The control signal may take three forms: forward acceleration, backward acceleration (deceleration) or normal driving. For normal driving, a range (R Œ#) of rotations per unit time is acceptable, the motor being forward accelerated until a level N is reached and being decelerated if it reaches an 'explosive' or overrun level E until it drops to level M. The intervals between N, M and the acceptable range are due to inertia of the motor.
