Patent GB-2192510-A (GB)
Title: Optical receiver
Inventor: JONES DAVID LLEWELLYN
IPC: H04B10/69
Filed: 1986-07-12
Abstract: In a fibre optic receiver, the modulated light beam to be received over an optical fibre falls on a photo-diode (A), and there is a second similar photo-diode (B) screened so that no light falls on it. These diodes are connected to the inputs of a differential amplifer (AI) whose output represents the difference between the currents in the diodes, and hence the signal on the incident light beam. This eliminates local-type interferences which are the same in both diodes, and enables a DC coupled receiver to be provided which has reasonably good sensitivity. In an alternative version the two diodes are connected in two arms of a bridge circuit whose output represents the signal on the incident light beam. <IMAGE>

Title: The extraction of particulate matter from vacuum processing apparatus
Inventor: DEARNALEY DR GEOFFREY
IPC: B01D45/10
Filed: 1986-10-09

Patent GB-2192739-A (GB)
Title: Selective input/output port protection
Inventor: BLANCK GREG J
IPC: G06F9/46
Filed: 1987-02-11
Abstract: Access to the ports of an I/O device (e.g. 37-40) is selectively controlled by values of respective bits stored in a bit map 42, (62 Fig. 4). An instruction from CPU 25 accessing a port is allowed direct access when the bit value for that port is a zero, but is trapped when the value is a one. A trapped instruction is either prohibited from any accessing or is rerouted via port virtualisation arrangement 34 for accessing a different I/O port. A particular bit pattern (70 Fig. 5) thus defines a given port access pattern for each user 21-24, and CPU instruction. Should a particular I/O device have a plurality of ports, access to the device as a whole may be determined by the use of "OR" logic applied to the bits for all of the ports of the device (Fig. 5). The CPU is part of a multiple user personal computer plus input/output system arrangement (Figs. 1, 2). <IMAGE>

Patent GB-2206411-A (GB)
Title: Analysis
Inventor: MAY KIETH
IPC: G01N33/52
Filed: 1988-06-30
Abstract: The relative proportions of glycated and non-glycated haemoglobin in a sample are determined by adding the sample to the first zone (12) of a device comprising a porous solid phase carrier incorporating two distinct zones (12,14). The first is capable of binding only glycated haemogiobin and the second is capable of binding any haemoglobin. The sample is eluted through the device by means of an eluting solvent and haemoglobin that has become bound in either zone is rendered visible by means of a colour-producing reaction which exploits the peroxidatic activity of haemoglobin. The relative intensities of the colour formed in each zone being thereafter used to provide an indication of the relative amounts of haemoglobin in the original sample. Binding of the glycated haemoglobin in the first zone is achieved by boronic acid residues linked to the carrier. The second zone may contain an ion-exchange resin. <IMAGE>

Title: Tamper-evident closure
Inventor: LIMITED JOHNSEN JORGENSEN PLAS
IPC: B65D41/34
Filed: 1988-09-20
Abstract: A tamper-evident closure comprises a cap part 1 with a depending skirt 5, a tear band 2 connected to the bottom of the skirt by frangible means 6, an annular anchor band 3 connected to the bottom of the tear band by frangible means 7 and a hinge connecting the anchor band to the skirt. The anchor band is divided into separate sections by frangible indicating means 9 extending across the width of the anchor band so that if an attempt is made to 'persuade' the closure off a container without tearing away the tear band the frangible indicating means will break as the closure is moved upwardly over a retaining bead around the neck of the container.

Title: Dispenser cathode
Inventor: SHON KYUNG-CHEON
IPC: C22C1/04
Filed: 1989-10-30
Abstract: A manufacturing method for a dispenser cathode is disclosed which comprises a step of immersing, in an aqueous solution containing an aluminum compound, a powder mixture made by mixing metal powder selected from among Mo, Ta and W or powder of alloys of at least two or more metals selected from among the carbonates of Sr, Ba and Ca; or immersing in said solution a pellet formed into a required shape from the former metal powder mixture whereby the aluminum ingredient in said aqueous solution is impregnated into said powder mixture or the pellet. According to the present method, a heat treatment at a temperature of over 1700 DEG C is not required unlike the case of conventional methods, and therefore, the decrease of the electron releasing efficiency due to the adverse reactions generated at the high temperature heat treatment can be avoided.

Title: Method of manufacturing a wall ironed can
Inventor: HEYES PETER JOHN
IPC: B32B15/09
Filed: 1990-07-28
Abstract: In a method of drawing and wall ironing a can body, a blank (1) is cut from a laminate of aluminium or alloy and a polyester film. The blank is lubricated and drawn to a cup (7) having a side wall (8), which is then wall ironed. A terminal margin (14) of the side wall (13) of the wall ironed can is heated to a temperature above 100 DEG C but below the crystalline melting point of the polyester film in order to prevent delamination of the polyester film from the side wall of the can during subsequent washing of the can. A benefit of the process is that the heating of the side wall margin (14) does not soften the aluminium or aluminium alloy body. <IMAGE>
