Title: Gripping device for separating threadedly connected components
Inventor: MUIRHEAD ROBERT
IPC: B25B13/44
Filed: 1993-03-30
Abstract: A gripping device has first and second gripping means 10, 12 which grip two separate components eg closure and container, which are threadedly connected, the gripping means being operatively connected for relative rotation to allow removal of one component from the other. Preferably each gripping means comprises a body part 1, 2 with a central aperture to receive a component, the component being gripped by the radially inner ends of elongate fingers 5, 6 which are pivotally mounted on the body part by pins (13, Figure 2) and adjustably protrude into the aperture on movement of handle 30, 40 relative to the body part. A protrusion carried on each finger 5, 6 projects into a slot in a cam ring (3, Figure 2) carried by the handle. By moving the handles 30, 40 in the directions of arrows 31, 41, the upper component gripped by fingers 5 may be unscrewed from lower component gripped by fingers 6. A friction washer and spring (71, 72 Figure 2) may be provided to oppose relative movement between flanged collars of the body parts. <IMAGE>

IPC: G06G7/163
Filed: 1993-09-14
Abstract: A multiplier has first and second quadritail circuits, each of which has two pairs of transistors whose capacities are the same and is driven by a constant current source I0. In the first quadritail circuit, inputs of a first pair Q9, Q10 respectively receive voltages +/-(V1+V2), and inputs of a second pair Q11, Q12 are connected in common to be biased by a middle point voltage of the voltage applied between the inputs of the first pair. In the second quadritail circuit, inputs of a third pair Q3, Q4 respectively receive voltages +/-(V1-V2), and inputs of a fourth pair Q5, Q6 are connected in common to be biased by a middle point voltage of the voltage applied between the inputs of the third pair. Differential outputs are provided by common-connected outputs of the first and fourth pairs and common-connected outputs of the second and third pairs. The multiplier produces the output (V1+V2)<2> -(V1-V2)<2>. Other embodiments are described producing (V1 +V2)<2>-(V1-V2)<2> or V1<2>+V2<2>- (V1-V2)<2>. At least one drawing originally filed was informal and the print reproduced here is taken from a later filed formal copy. <IMAGE>

Patent GB-2284230-A (GB)
Title: Sashlocks
Inventor: BELCHER LEONARD HUMPHREY
IPC: E05C1/16
Filed: 1993-11-26
Abstract: The sashlock comprises a casing containing a spring-loaded bolt 23 and a rotatable follower 32. The follower 32 has an arm 36 at the end of which is provided a projecting boss 37 that extends into an aperture 28 in a plate 26 associated with the bolt 23. The association between the follower 32 and the bolt 23 forms a lost motion mechanism such that rotation of the follower 32 causes the boss 37 to engage the plate 26 to retract the bolt 23 but retraction of the bolt 23 by a force applied to the bolt does not rotate the follower 32. <IMAGE>

Title: Electromagnetic contactor
Inventor: HURLEY RICK ALAN
IPC: H01H47/32
Filed: 1994-02-25
Abstract: An electrical contactor 20 has first 25 and second contacts movably mounted to engage for achieving continuity in an electrical circuit, via an electromagnet 22 and armature 24 defining a magnetic circuit with an air gap that closes in a first position of the contactor and opens in a second position of the contactor. A controller 30 switches an alternating current voltage to the coil 23 of the electromagnet during a timed portion of each AC half cycle, and senses 68 the current level in the coil in a feedback loop. The controller adjusts the voltage-on time to achieve a predetermined average current as needed for accelerating the armature or coasting during a closing operation, for holding the armature in place when closed, etc. In order to sense whether the contractor is presently open or closed, the controller monitors and stores the phase angle between the previous voltage zero crossing and the time of voltage turn-on. When when the inductance of the magnetic circuit changes rapidly due to opening or closing of the air gap the controller detects a corresponding variation in the phase angle. <IMAGE>

Title: Energy-saving image forming apparatus
Inventor: KIM YONG-GEUN
IPC: G03G21/00
Filed: 1994-10-19
Abstract: An image forming apparatus, eg a laser printer, copies or fax machine, and a control method therefor may be automatically activated when a user does not use the apparatus for a predetermined period of time, by initiating a primary energy saving mode where power to a primary energy saving circuit portion of the apparatus is turned off. The circuit portion includes a heat lamp for fixing and a ventilating fan. To achieve even greater energy savings, a secondary energy saving mode is established in response to a user input. During a secondary energy saving mode, power to the primary energy saving circuit portion and a secondary energy saving circuit portion, including an image processor, is turned off. While in the secondary energy saving mode, a reactivation key may be entered by the user. Entry of the reactivation key initiates a warm-up operation to bring the apparatus to a print ready state. <IMAGE>

Title: A side impact airbag deploying from a flexible pocket, attached to the vehicle at two points
Inventor: JOST STEFAN
IPC: B60R21/213
Filed: 1995-09-08
Abstract: An inflatable cushion (8) in the deflated state is folded and mounted in a flexible pocket (5) and is fixedly attached to the vehicle at at least two spaced positions (13, 4). The flexible pocket comprises a line of weakness such as a tear (6) seam along which the pocket opens during inflating of the cushion and through which the cushion deploys. The flexible pocket (5) is preferably fabric and the tear seam (6) comprises a stitched seam the stitches of which either break or unravel when the airbag cushion is deployed. The airbag cushion with or without the appropriate inflator (1) may be mounted either in the vehicle seat or in the roof or in a structural side beam such as the B pillar. The tear seam is preferably aligned with a seam of the seat cover (or the roof lining) so that both seams tear together on deployment of the airbag cushion. This form of flexible pocket tear seam allows for a much more controlled deployment of the bag reducing some of the initial forces which can in themselves cause damage to the occupant, yet at the same time allowing deployment of the bag within the required time frame of 2 to 4 milliseconds. A manifold for connecting the inflator to the cushion is described which protects the cushion mounting area from the direct effects of the hot gas from the inflator and allows a mounting angle between the inflator and the cushion of anything between 0 and 180 DEG . <IMAGE>

Title: Fuel injector driver with raised initial current
Inventor: BROWN GARRY
IPC: H02H9/04
Filed: 1993-07-22
Abstract: A switch mode fuel injector circuit comprises a main switch 14, a recirculation switch 20, and a current detector 18. The solenoid 16 current is regulated by the control circuit 24 such that an initial peak current period (figure 2) is followed by a holding current period.
