Patent GB-2209558-A (GB)
Title: Rear face hinge
Inventor: TETSELL MARK JOHN
IPC: E05D3/12
Filed: 1987-09-05
Abstract: A rear face hinge for mounting on the rear face of a door or particularly on the rear face of a pivotally-mounted access panel for a ceiling. Where the access panel is to be faced with tiles intended to match with a tiled surface of the ceiling in which the access panel is fitted, it is not possible to use visible hinges or parts thereof between the abutting hinged edges of the access panel and the ceiling as this would spoil the otherwise uninterrupted apparently continuous appearance of the tiled surfaces. Also if conventional rear face hinges were to be used there would be insufficient clearance at the hinge line to enable the access panel to be opened without interference between the adjacent edge of tiles on the access panel and the tiled ceiling surface. Therefore the rear face hinge is of Z-shape and has a first leaf 10 to be secured to the rear face of the access panel 5, an intermediate second leaf 11 pivotally connected to the first leaf about a first hinge line 14 and a third leaf 12 to be secured to supporting structure positioned behind and spaced from the rear face of the access panel when closed, the third leaf 12 being pivotally connected to the second leaf 11 about a second hinge-line 15 parallel to the first hinge-line 14. <IMAGE>

Title: Recombination electric storage cells
Inventor: HAYMAN JOHN ANDREW
IPC: H01M50/417
Filed: 1988-01-14
Abstract: A recombination electric storage cell comprises a container which contains alternating positive and negative plates interleaved with separators and is full of electrolyte. The separators comprise sheets of polypropylene fibres whose pores are normally substantially filled with electrolyte. When gas is evolved at the plates on overcharge of the cell the electrolyte is expelled from a proportion of the pores whereby oxygen produced at the positive plates diffuses through the separators and is recombined at the negative plates.
Patent GB-2222897-A (GB)
Title: Vehicle navigation system
Inventor: ZEEVI ELIAHU IGAL
IPC: G01C21/34
Filed: 1988-04-08
Abstract: A vehicle navigation system is provided wherein a preselected route is established in terms of a sequence data and processing means computes sequence action data based on lineal distances between landmarks, such as junctions, and movement detecting means, such as a turn detection, for detecting movement only around an approached landmark in order to synchronize position with the landmark. It is unnecessary to store all geographic data about a region to be traversed during a journey and further computation can be extremely efficient without reliance at any time on detection of direction with respect to magnetic north or other fixed, remote reference. All needed information is incorporated into data related only to distance travelled by the vehicle between landmarks and movement around (e.g. turns) an approached landmark. The system works on the assumption that the vehicle moves in one dimension between predetermined landmarks so that route information can be reduced to a sequence of indicators. The movements around landmarks, or more specifically junction or turns where deviations are expected from a straight line constant velocity path are used to synchronize vehicle location relative to the landmark. The accuracy of map distance between landmarks is assumed within an acceptable error so that synchronization can be obtained within a window distance during which the system seeks synchronization. <IMAGE>

Title: Non-destructive material evaluation apparatus
Inventor: IMHOF ROBERT ERIC
IPC: G01N21/17
Filed: 1989-10-24
Abstract: The apparatus is for measuring photo-induced reflectance changes of a material 5 and comprises a pump source 2, an optical modulator 3 and optics 4 to deliver an intensity modulated beam to a test area of the material. The optics functions to produce a diffraction grating pattern on the test area. An optical probe source 3 delivers a probe beam through optics 9 onto the same test area of the material and the reflected beam 18 is detected by a detector 11 forming part of a sensor arrangement 12, 13, 14. The diffraction grating pattern on the test area causes the reflected beam to be one of several angularly separated reflected beams 16, 18 and the detector is aligned to receive the beam 18 rather than the beam 16 which lies in the direction of specular reflection when the photo-induced pattern is absent. <IMAGE>

Title: Proximity switch incorpotating non-critically damped oscillator.
Inventor: CALDER DOUGLAS WILLIAM HUDSON
IPC: H03K17/95
Filed: 1991-12-31
Abstract: When a critically damped oscillator is used in inductive proximity sensors there is no electrical information regarding the target position when the target is closer than the detection distance. This is detrimental to the speed of operation of the proximity sensor when the target is removed. The invention, therefore, provides a proximity switch circuit including first and second transistors (Q4, Q6) connected as a long tail pair with an inductive sensing circuit (LC) connected to one leg thereof and an emitter follower circuit (Q7, Q8) connected between said one leg and the base of the transistor of the other leg, whereby an oscillator circuit can be provided which is non-critically damped to enable faster speed of operation of the proximity switch.

Title: Producing a die for automobile fisheye lens
Inventor: OTSUKA YOSHINORI
IPC: B29C33/42
Filed: 1992-12-09
Abstract: A method of producing a die for use in forming fisheye steps in an automobile lens having both straight and curved portions. The die comprises plural concave portions that are arranged to form the fisheye steps when applied in a lens forming process. In the die producing method, the boundary lines between concave portions corresponding to the respective fisheye steps are connected to produce approximately a straight line, to thereby improve an appearance of the fisheye steps. Further, the concave portions f, f that are divided by longitudinal lines i, i extending in a first direction and lateral lines j, j obliquely intersecting the longitudinal lines and extending in a second direction are produced by NC machining using an end mill. The lateral lines are formed so as to be connected to assume a straight line, so that the boundary lines of the fisheye steps as a formed product by the die thus machined become smooth (not zigzagged) continuous lines. <IMAGE>
