Title: Optical switch
Inventor: DORSEL ANDREAS
IPC: G02B6/34
Filed: 1991-04-19
Abstract: An optical switch (15) conducts radiation from a source (10) into a fiber (15f) leading to a sensor and conducts radiation returning from this fiber onto an optoelectric receiver (19). A beam splitter (13a) splits off a component of the radiation emitted by the source (10) as a reference beam (13r) which is guided via deflecting prisms (16u, 16p) and spacers (16s, 16d) to a second beam splitter (13b). The second beam splitter (13b) geometrically superposes the reference beam (13r) onto the measurement beam (15m) returning from the fiber (15f) via the optical switch (15). An air gap (18) ahead of the second beam splitter (13b) accommodates a movable diaphragm (18b) which alternately interrupts the measurement beam (15m) or the reference beam (13r). The optical switch (15) includes a filter (14f) having wavelength-dependent transmission and reflection characteristics as well as optical components (12) for collimating or focusing. <IMAGE>

Title: Method of forming multi-color image for colour proofs
Inventor: OMOTE HISAHIRO
IPC: G03F7/004
Filed: 1991-11-25
Abstract: A method of forming a multi-colour image for color proofs on an image-receiving material such as paper using a colored photosensitive transfer sheet and an intermediate image-receiving sheet without using heat sensitive adhesive layers is disclosed. The transfer sheet comprises a support, a release layer and a colored photosensitive layer of a colored pigment and containing a synthetic resin emulsion with Tg = -20 to 40  DEG C 0.9. acrylic ester or ethylene-vinyl acetate copolymer so that the layer itself has heat-adhesivity. Image-receiving layer of the intermediate image-receiving sheet comprises a resin cross-linked copolymer of an olefin and  alpha , beta -unsaturated carboxylic acid with metallic ions and a resin comprising a copolymer of ethylene and vinyl acetate in proportions by weight of 100/0 to 10/90. In first transfer, the support and release layer of the transfer sheet are peeled off and in the second transfer, the support and image-receiving layer of the intermediate sheet are peeled off. By this means the image layer alone can be transferred onto the image-receiving material, thus a color-proof close to a print formed with inks alone can be produced.

Patent GB-2262465-A (GB)
Title: Casting of aluminium-lithium alloys
Inventor: EVANS BRIAN
IPC: B22C3/00
Filed: 1991-12-16
Abstract: Aluminium-lithium alloys show poor suitability as casting materials due to the occurrence of sub-surface porosity in the casting which results from adverse reaction between the molten alloy and the materials used in the manufacture of suitable moulds. In order to prevent this, the mould is first treated with a silylating agent such as trimethylchlorosilane which reacts with free -OH groups in the mould material, thereby passivating the mould surface towards molten lithium. Trial castings made in moulds thus-treated have a much cleaner as-cast surface and show insignificant sub-surface porosity. The silylating agent may be applied by dipping, spraying, or use of a carrier gas. e.g. nitrogen.

Title: Security systems.
Inventor: ELLIS ANTONY MARK
IPC: B60R25/10
Filed: 1992-05-02
Abstract: The security system involved in the arming and disarming of a car alarm, includes a transmitter (2) and a receiver (4) each including an oscillator (6, 8) incorporating a highly accurate and stable quartz time base. Each oscillator (6, 8) drives a respective encoder (14, 20) to develop a pseudo random succession of codes. Reset switches (10, 12) are provided for both transmitter and receiver (2, 4) to synchronise the two oscillators and therefore to synchronise the succession of codes. The receiver (4) includes a decoder (24) for decoding the received signals and a comparator (26) for comparing the decoded signal with the signal generated by the encoder (20). When equality is detected an arm/disarm circuit (28) is triggered. Because the codes of the transmitter and receiver are continually changing, it makes it very difficult for a thief to produce a coded signal which will trigger the arm/disarm circuit.

Inventor: LILIE DIETMAR ERICH BERNHARD
IPC: B21D7/14
Filed: 1992-08-13
Abstract: A method of bending metallic blades for use in reed valves of hermetic compressors involves bending through a first angular displacement which corresponds to an expected deformation between 60% and 90% or 110% to 120% of the desired deformation. The actual deformation is then measured to deduce a new displacement to deformation relation. A further displacement is calculated from the new relation, and applied. A number of displacements are determined and applied in succession until the desired deformation is achieved. <IMAGE>
Patent GB-2261283-A (GB)
Title: Liquid transfer device for diagnostic assays
Inventor: BUNCE ROGER ABRAHAM
IPC: B01L3/00
Filed: 1992-11-10
Abstract: The device, for biochemical diagnostic assays comprises two liquid flow channels of porous material which transfer liquid by capillary flow to a common site in sequentially timed manner following simultaneous application of the liquid to the ends of the channels. The channels interconnect at a certain point and then both continue in an arrangement analogous to an electrical bridge circuit. By selecting the hydraulic resistances of the arms of this circuit the flow can be controlled across the bridge. Balancing the circuit will produce null flow across the bridge and prevent the flow from the channel from dominating that from the other when the channels are saturated. Alternatively the arrangement can be such as to produce oscillating flow across the interconnection. Typical use is an immunoassay using serum or urine samples and immobilised antibody binding.
