Title: Handle for particulate material handling implement
Inventor: ANDERSON NEIL ALASTAIR
IPC: A01B1/02
Filed: 1991-08-28
Abstract: A particulate material handling implement 1 for use with only one arm comprises a head portion 2 and a handle 4. The handle 4 comprises an elongate shaft 6 connected at one end thereof to the head portion 2. A forearm support member 10 is provided at a second end of the shaft 6 and a grip member 12 is positioned between the forearm support member 10 and the head portion 2. The grip member 12 projects from the shaft 6 and is formed and arranged with the forearm support member 10 so that the handling implement 1 may be used one-handed with the grip member 12 gripped in one hand 24 and the shaft 6 extending along the forearm such that substantially all the forearm is in engagement with the forearm support 10 when lifting the implement 1. The head portion may be in the form of a shovel, a brush, a fork, a rake or a hoe. <IMAGE>
Patent GB-919355-A (GB)
Abstract: 919,355. Measuring rotor unbalance electrically. AVERY Ltd., W. & T. July 20, 1959 [Aug. 11, 1958], No. 24784/59. Class 40 (1). In a dynamic rotor unbalance measuring system the unbalance components and neutralized electrically, the system calibrated with known weights, and the neutralizing components then measured. As shown (Fig. 1), the unbalance of a star 101 at its bearing planes is determined by rotating it at the desired speed by a motor 103, and measuring the vibrations at the bearings by pick-ups 110, the signals being combined with proportions of sine and cosine voltages from a synchronously driven generator 106, as chosen by potentiometers P1- P4, in such a way that each unbalance component, chosen by switch 107 and indicated on meter 108, is zero. A known unbalance weight is now added to the left compensating plane L, and potentiometers P5, P6 are adjusted so that no unbalance occurs in the right compensating plane R: a known weight is similarly added to the right compensating plane R and potentiometers P7, P8 adjusted so that no unbalance change occurs in the left plane L. Since the unbalance weights are known, the sensitivity of the meter readings is established. The bearing bridges 102 are now clamped by arresting devices 113, and the only signals fed to meter 108 are the proportions of the sine/cosine voltages from generator 106 which exactly neutralize the unbalance signals, and which therefore measure the unbalance components, after reversing the polarity by switch 114 or 115. In modifications, the arresting devices 113 are replaced by clutches between transducers 110 and rotor 101, or the signals from the pick-ups 110 are switched out and replaced by equivalent value resistors. Specification 735,657 is referred to.

Title: Controlling engine supercharging pressure.
Inventor: KURIHARA MASARU
IPC: F02B37/18
Filed: 1993-07-15
Abstract: A wastegate valve controls the flow rate of exhaust gas applied to a turbine of a turbocharger and an actuator controls the wastegate valve. A standard supercharging pressure at which the wastegate valve opens is determined, this being dependent on the characteristics of the wastegate valve, and a desired supercharging pressure is set in accordance with engine operating conditions. The difference between the desired supercharging pressure and the standard supercharging pressure is calculated, and a ratio of the difference to a detected actual supercharging pressure is calculated. From the calculated ratio, the duty ratio of a solenoid valve which connects the actuator with the engine intake upstream and downstream of the turbocharger compressor is calculated and thus the opening of the wastegate valve determined.

Title: Process for controlling a torque transmission system
Inventor: RINK ANTON
IPC: F16H59/36
Filed: 1993-08-21
Abstract: A process is disclosed for controlling a torque transmission system having a hydraulic torque converter (11) and a friction clutch (12) for bridging the hydraulic torque converter (11), as well as a bridging clutch and a hydraulic torque converter for such a system. This control process is a moment control in which the input torque supplied by a driving unit is subdivided into a torque to be transmitted by the converter (11) and into a torque to be transmitted by the lock-up clutch (12). In the briding clutch, the radially outer side of a ring piston centrally arranged between the converter lid and the turbine wheel is designed as a clutch disk and its radially inner side is received on a counter-sealing hub. The convertor is "soft" and has a flat primary characteristic curve and a broad secondary characteristic field, thus a large conversion range. <IMAGE>

Title: Stratified charge engine
Inventor: MA THOMAS TSOI-HEI
IPC: F02M25/07
Filed: 1994-10-04
Abstract: Two manifolds 24, 34 have branches 22, 32 that are configured to supply two gas streams to the intake valve 14 of each cylinder. The two streams enter the cylinder separately through the valve 14 so as to produce a stratified charge within the engine cylinder. The manifold 24 supplies a metered quantity of air within which the fuel to be burnt is dispersed when the charge is in the engine cylinder and the manifold 34 supplies EGR gases or air under the control of a valve 90. A non-return valve 23 is arranged in each branch 22 to permit gases to flow in the branch only in the direction towards the intake valve 14. The manifold 34 may have branches (32, 32', Fig. 3) leding to each cylinder intake valve to provide lateral rather than radial charge stratification. Fuel is supplied to the individual branches 22 through injectors 60, to the manifold 24 or direct to the cylinders. The valves 50, 84 controlling flow to the manifolds 24, 34 may be linked to vary the flows in inverse proportion. <IMAGE>

Title: Three-dimensional engraving using photoresists
Inventor: COWAN JOHN RICHARD
IPC: B24C1/04

Abstract: A continuous tone image A is used to expose photoresist C through support B and developed to produce a resist of different depths. Support B is stripped off and resist C is bonded by adhesive E to the substrate F prior to shotblasting. As shotblasting proceeds, firstly the least resistant areas and then gradually the relatively more resistant areas of the resist are progressively worn away, exposing the different areas of the substrate to the shotblasting process for different amounts of time and thus producing in the substrate an image comprising differential depths of erosion as predetermined by the various levels of resistance built into the image in the resist. <IMAGE>
