Title: Child's safety seat
Inventor: BIRCH ALAN RICHARD
IPC: F16B2/18
Filed: 1991-09-28
Abstract: A child's safety seat for mounting on a passenger seat of a vehicle is secured in place by a safety belt (14) provided in the vehicle. To locate the safety belt clamping guides are provided each having a fixed bearing element (18), a fixed carrier element (19) and a wedge element (20). Adjacent faces (26) of the wedge and carrier elements are formed with complementary V-shaped cam profiles (26, 27). When the cam profiles are in their mean relative positions a seat belt may be inserted between the wedge element (20) and the bearing element (18). Lateral displacement of the wedge element (20) from its mean position. through interaction of the V-shaped profiles, causes the gap between the wedge and bearing elements (20, 18) to close so locking the seat belt (14) therebetween. <IMAGE>

IPC: B65G47/252
Filed: 1993-05-05
Abstract: Cylindrical cans (104) or the like are conveyed upright from filler and closure equipment (100) to a receiving area and into hydrostatic sterilizer carriers (108). A screw assembly (102) is periodically actuated, taking cans (104) from the receiving area, grasping their cylindrical sidewalls and laying them down and forward into a metered can stick which is rolled laterally by a clamp-kicker assembly (106) into the hydrostatic sterilizer carriers (108) as they are conveyed past it. The screw assembly (102) includes a pair of horizontally disposed screws (114, 116), both rotatable downwardly and inwardly and with the axis of one spaced above that of the other. With one complete rotation of the screws (114, 116) a can (104) held therebetween on its cylindrical sidewalls is positively laid forward onto its side. If a sensor (177) detects that a can (104) being conveyed to the screws (114, 116) has fallen down then the rotation of the screws (114, 116) is automatically stopped. <IMAGE>

Before the precipitation hardening, the gamma' phase is completely dissolved by solution annealing. This alloy is substantially more suitable for the casting of directionally solidified components than nickel-based superalloys according to the state of the art and, in addition, has a creep life which is considerably improved as compared with these alloys.

Title: Methods of preserving cut flowers or foliage
Inventor: JENNINGS LAWRENCE
IPC: A01N3/00
Filed: 1994-03-17
Abstract: A method of making preserved plant material having the colour and texture of fresh plant material and substantially free from curling or distortion, comprises the step of immersing the plant material in an aqueous solution comprising from 40% to 95% by volume of one or more C3 - C6 dihydric alcohols at a temperature of from 60 DEG C to 95 DEG C. The dihydric alcohols preferably comprise a major fraction of propylene glycol. The immersion is preferably carried out for from 5 to 90 minutes at a temperature of from 65 to 85 DEG C. The aqueous solution may also contain dehydrating alcohols and/or polyethylene glycol. The aqueous solution of the dihydric alcohols exchanges for aqueous sap and juices in the plant material, e.g. cut green foliage or cut flowers, without changing the colour or texture of the material. The plant material may also be preserved by dipping in an aqueous solution or suspension of a polymer and drying to leave a layer of polymer on the surface of the plant material.

Title: Slip compensation method in a squirrel cage induction motor
Inventor: TOERMAE JUHA
IPC: H02P27/06
Filed: 1994-09-15
Abstract: A method for slip compensation in a squirrel cage induction motor 2, when the motor is fed by an inverter 1 without feedback at a supply frequency less than 20% of the rated supply frequency of the motor after the motor has first been fed at a frequency more than 50% of the rated frequency for a period of time at least equal to a mechanical time constant of a combination formed by the motor and a load device, wherein a term (kT) proportional to the torque of the motor is determined and added to the set value of the rotation speed (n) to effect slip compensation. To improve the compensation accuracy, the value of said compensation term is stored in a memory before transition from the frequency more than 50% of the rated frequency to a frequency less than 50% of the rated frequency, and the stored compensation term is used as such for slip compensation when the supply frequency of the motor is less than 20% of the rated frequency. <IMAGE>

Title: Position detection using time-division multiplexing
Inventor: UMEDA YUICHI
IPC: G06F3/033
Filed: 1995-06-29
Abstract: In a relative angle detecting arrangement, light from a light source is detected by a plurality of detector elements (5) and the detector outputs are subjected to time division (12). The received light detection voltage is shifted by a phase shifter (21) and a sampling pulse is formed. Peak detecting means (19) holds a peak value of each received light output based on the sample pulse. In a CPU (26), the peak value of each voltage is stored in a memory, and the stored values are operated on arithmetically to provide information regarding the relative position between the light source and the light reception elements. Utilizing the time division, each received light detection voltage can be processed in the same processing path, as opposed to prior arrangements where each detector element had its own associated processing path. The arrangement may be used in a movable input device, such that its position relative to alight source mounted on eg a computer may be detected and displayed on the computer screen (Fig. 9, not shown). <IMAGE>

Title: A braking system for a vehicle
Inventor: LEONARD ROBERT C
IPC: B60T8/1764
Filed: 1995-11-27
Abstract: A braking system for a vehicle having ABS comprises at least one axle where the wheels are subjected to the same brake pressure, and a respective wheel speed sensor 120 at each wheel of that axle. The brake pressure to the axle is subject to a "select-low" control mode, so that the first wheel on that axle to skid causes axle braking pressure reduction. After this brake pressure reduction and detection of split-mu conditions at the axle, the control mode is changed into a "select-high" control mode wherein the buiid-up of axle pressure is continued at a controlled rate above the pressure at which skidding occurred for at least a second time on the first wheel on said axle to skid. The system is also responsive to front and rear axle loads.

Title: Torque variation restraining device of engine accessory driving system
Inventor: ISHIHARA AKIRA
IPC: F16F15/02
Filed: 1994-06-08
Abstract: A torque variation restraining device of an engine accessory driving system for restraining variations in revolution and/or torque of a driving shaft gear system produced as the driven torque of an engine accessory rapidly changes so as to reduce gear grating noise from an engine gear system, thereby making it possible to reduce the load on the tooth surfaces of the engine gear, wherein a certain gap is formed between a retainer (4) and an engine accessory driving shaft (1), wherein a friction damper (6) surrounding the engine accessory driving shaft (1) is disposed in this gap, and wherein oil supply means (10) having engine lubricating oil introduced therein is provided between the friction damper (6) and the retainer (4), whereby the friction damper (6) is brought into contact with the driving shaft (1) by virtue of the pressure of the lubricating oil, a friction braking force to the driving shaft (1) resulting from the contact increasing as the lubricating oil pressure increases with the increase in the engine speed. The present invention is concerned with a torque variation restraining device of an engine accessory driving system. It is possible to reduce the gear grating noise of the engine gear system and reduce a load on the gear tooth surfaces by restraining torque and/or rotation variations of the driving shaft and the gear system, which variations are generated as the driven torque of the engine accessory varies sharply. For this purpose, a space is provided between a retainer (4) and the driving shaft (1) of the engine accessory, a friction dumper (6) which surrounds the outer periphery of the driving shaft (1) of the fuel injection pump is disposed in this space, and oil supply means (10) having engine lubricating oil introduced therein is disposed between the friction dumper (6) and the retainer (4). The friction dumper (6) is brought into contact with the retainer (4) by a lubricating oil pressure, and the frictional braking force to the driving shaft (1) resulting from this contact increases as the lubricating oil pressure increases with an increase in the engine rotation speed. <IMAGE>
