Title: Squeegee device for supplying ink in a stencil printing device.
Inventor: HASEGAWA TAKANORI
IPC: B41L13/18
Filed: 1992-09-09
Abstract: In a squeegee device 5 for supplying ink in a stencil printing device from the interior of a cylindrical, ink permeable printing drum 1 which rotates around an axial line C thereof with a stencil master plate wrapped around the outer circumferential surface thereof, to prevent a squeegee blade 41 from developing a juddering movement relative to the cylindrical printing drum, and to allow the squeegee blade to sufficiently intimately contact the inner circumferential surface of the printing drum so that printing ink may be supplied to the printing drum by a prescribed amount in a stable fashion at all times, a thin spring plate 43 is placed on a reverse surface of the squeegee blade which is made of a rubber-like elastic material which is in engagement with the inner circumferential surface of the cylindrical printing drum. The spring property of the thin spring plate appropriately controls the elastic deformation of the squeegee blade, and. even when the squeegee blade is made of readily deformable rubber-like elastic material, and the increase in the rotational speed of the cylindrical printing drum is increased, the squeegee blade is prevented from developing a juddering movement relative to the cylindrical printing drum. <IMAGE>

Title: Reinforced box lintel
Inventor: FOX DAVID MARTIN
IPC: E04C3/02
Filed: 1992-10-05
Abstract: A box lintel fabricated from sheet metal comprises a skin made by placing together L-shaped components (11) and (12) so that terminal flanges (13) and (14) of the top and bottom overlap the sides (15) and (16) at diagonally opposed corners (19, 20). Within the box is a reinforcement element (21) having opposed flanges (23, 24) at opposite ends of a web portion (22). When the lintel is placed under load the web (22) tends to bow such that the flanges (23, 24) are deflected in the directions of arrows A and B. This applies compressive forces to the overlapping areas of the shin components (11, 12), tending to rigidify the box, and avoids the necessity for riveting (28, 29) other than at end regions of the reinforcement element. Reinforcement (21) may take the form of 2 C-shaped members back-to-back. The lintel may have a sill as in Fig 4, not shown. <IMAGE>

Title: Ii-vi epitaxial layer on (111) substrate
Inventor: EBE HIROJI
IPC: H01L21/20
Filed: 1993-01-26
Abstract: A group II-VI epitaxial layer 5, such as CdTe, is grown on a crystalline (111) substrate 4 having a diamond or zinc- blende structure, such as silicon, GaAs, or GaAs on silicon, in such a way as to minimise lattice mismatch between the II-VI epitaxial layer and the silicon. The II-VI epitaxial layer also has a (111) plane at the interface, but a 30 DEG  in-plane rotation slip is formed at the interface between the (111) silicon substrate and the group II-VI epitaxial layer. This structure is obtained by a metal-organic chemical vapour deposition method (MOCVD), in which the mol ratio of the group VI gas source supply eg dimethyl telluride to the group II gas source supply eg dimethyl cadmium is kept greater than 15 during the growth. The (III) silicon substrate is preferably mis-oriented towards its <110> direction. An alternative II-VI layer is CdZnTe, eg Cd0.45Zn0.55Te, and a layer of HgCdTe may be grown on the epitaxial layer. When a HgCdTe layer is grown on the epitaxial layer, the product thus formed can be used as a monolithic infrared detector in which detector elements are formed in the HgGdTe layer and a signal-processing circuit is formed in the silicon substrate. <IMAGE>

Title: Mass addition detector
Inventor: EDWARDS DAVID GEOFFREY
IPC: B60R25/10
Filed: 1993-04-19
Abstract: The mass addition detector is particularly suitable for use with vehicles. The detector senses change in mass using a combination of one or more load sensors (21) adapted to detect small changes in the mass of a stationary vehicle, discrimination means adapted to discriminate between long term and short term changes and alarm means adapted to provide an indication of any long term mass changes. Preferably, the or each load sensor (21) is attached within the body of the vehicle, for instance by association with the suspension system (23). In one form at least one load sensor (21) is associated with a spring suspension system (23) and senses relative movement between the vehicle body (24) and the spring (23). In an alternative form the load sensor is located on a surface of a resilient mounting bush (22) mechanically joining the spring and the vehicle body. The load sensor may be provided with sensor control means to engage and disengage the sensor from the suspension system. The preferred load sensor is a strain gauge. The discrimination means is a microprocessor programmed to analyse the signals and programmed to analyse the signals so that when a mass change exceeds a predetermined magnitude and lasts for a predetermined time period an alarm signal is produced.

Title: Method of sorting particulate material
Inventor: ROSS VICTOR EMUL
IPC: B03B1/00
Filed: 1993-08-11
Abstract: Particulate material is sorted according to the thermal properties of the particles. The particles (24, 25) to be sorted are initially all cooled to a temperature below the freezing point of a liquid, e.g. water. The cooled particles are then placed on a surface (14) and contacted with the liquid. This has the result that the liquid freezes in the localities of the particles to adhere them to the surface. Heat is then to the particles and those particles (24), eg diamonds, with higher thermal diffusivity gain heat more rapidly than other particles (25), eg gangue, and are released first from the surface. Finally, particles (24) which have been released from the surface and those particles (25) which have not been released from the surface after a certain time lapse are collected separately. <IMAGE>

Title: Catalytic converter system
Inventor: SERVATI HAMID BEYRAGH
IPC: F01N13/02
Filed: 1994-04-06
Abstract: An apparatus for controlling temperatures of catalytic converters in an exhaust system of an internal combustion engine. The exhaust system includes a light-off catalytic converter 14 and a main, or underbody, converter 16. The light-off catalytic converter is smaller and is disposed nearer to the engine than is the main catalytic converter so that it can be brought to an efficient operating temperature by engine exhaust gases in less time than can the main catalytic converter. This reduces the output of initial undesirable exhaust emissions during start-up periods when the engine and exhaust system components are relatively cold. Valves 18, 26 control the flow of exhaust gases through each of the two catalytic converters to bring them most quickly to, and maintain them at, their most efficient operating temperatures. Engine control unit 34 receives data about running conditions from many sources including convertor thermocouples 28, 30 and uses valve motors 36, 38 to adjust the gas flow accordingly. <IMAGE>

Title: Emergency shutdown valve
Inventor: RUESSE ROLF
IPC: F16K15/18
Filed: 1994-06-01
Abstract: An emergency shutdown check valve (10, Fig. 1) having a check plate (34) which pivots about an axis (40) to open and close a bore (18) through the valve housing (12) to limit fluid flow through the valve (10) to one direction only (from direction 14 to 16) during functioning as a check valve during which plate 34 occupies generally the figure 1 position. The check plate (34) can be lifted clear of the bore (18) by a plate-lifting mechanism (42 - 50) to the figure 2 position to allow bi-directional flow and/or the passage of a pig. In its raised position (Fig. 2), the check plate (34) can be latched up by a latch mechanism (52 - 66) whose operation requires constant pressurisation of a linear actuator (60). A built-in spring (68) biasses the latch mechanism (52 - 66) to a delatched state in which plate 34 falls through gravity, as a result of its displaced mass from pivot axis 40, to the figure 1 position to provide for automatic fail safe reversion to check valve functioning. The valve (10) is particularly applicable to the protection of submarine hydrocarbon pipelines and facilities connected thereto. <IMAGE>

Title: Fixing frames in buildings
Inventor: MOLYNEUX GEORGE
IPC: E06B1/60
Filed: 1994-01-04
Abstract: The invention provides retractable retaining elements (234), such as spring clips, on either the subframe or the window or door frame (200), which have to retract to allow the window or door frame (200) to be fitted, but which spring outwardly when the window or door frame arrives at its fully fitted position to retain that frame. In addition to the retaining element (234) there is a locking device (256), which is manually operably by turning and which, when operated, applies a locking force nullifying the resilience of the retaining element. Hence, the retaining element can be very pliant, to allow easy fitting of the window or door frame, but once the window or door frame is in position, the resilience is cancel led, so as to provide a rigid stop, preventing withdrawal of the window or door frame. <IMAGE>

Title: Torsion vibration damper
Inventor: ALBERS ALBERT
IPC: F16F15/137
Filed: 1994-09-27
Abstract: A torsion vibration damper which can be used between an internal combustion engine and a gearbox of a vehicle has an input part and an output part which can rotate relative to each other against the action of long coil springs 107 mounted on a comparatively large diameter. The springs 107 produce a friction which is dependent on centrifugal force and operates in parallel with the spring action thereof. As a result, the dynamic torsion resistance produced by the energy accumulators increases in dependence on speed. A spring element 118 having a spring suspension which acts between the input part and the output part and in practice is not restricted by the centrifugal force is provided in series with at least one of the energy accumulators 107. <IMAGE>

Title: Method for generating a spectral noise weighting filter for use in a speech coder
Inventor: GERSON IRA A
IPC: G10L19/12
Filed: 1994-01-18
Abstract: Analysis by synthesis calculates a difference by subtracting (130) synthesized speech from input speech. The synthesized speech is formed by exciting long and shortfitters (124, 126) with excitation vectors from a codebook store (114) which is searched by codebook generation (120).A weighting filter (132) is applied to the different signal and the weighted difference is used to calculate an energy measure (134) which is used to control the codebook search (140). The weighting filter is a Rth-order filter controlled with calculated coefficients. The method for calculating coefficients models the frequency response of L Pth-order by a single Rth-order filter, where the order R < L x R This method increases the control of a speech coder filter without an increase in hardware complexity. <IMAGE>

Title: Limiting the speed of a motor vehicle
Inventor: LINDEN THOMAS
IPC: B60K31/04
Filed: 1996-03-12
Abstract: In addition to cruise controllers for maintaining a predetermined speed, devices are known which attempt to keep the vehicle speed below an adjustable maximum speed by reducing the power in the event of an infringement. The present method intervenes to limit the engine torque while the actual speed is still below the maximum speed, but a demand by the driver for a speed above this is detected. An acceleration-regulation takes place first and, if the speed approaches the maximum speed further, a speed-regulation takes place, allowing the actual speed to be brought gently to the set maximum speed. In the case of speeds demanded by the driver which are below the maximum speed, the driving response remains determined solely by the driver. It is advantageous to combine the speed limitation with cruise control, with selective activation of one of the two operating modes.
