Patent GB-2270446-A (GB)
Title: Establishing a common cryptographic key at two cryptographic sites
Inventor: HOLLOWAY CHRISTOPHER J
IPC: H04L9/08
Filed: 1992-09-04
Abstract: The method includes preparing a portable data processing device ("smart card") at each site having a first data record which can only be read at that site but which can be written to at any site, and a second data record which can only be written at that site but which can be read at any site, the device also containing a testable key particular to that device. Each site also creates and publishes a set of test patterns against which the authenticity of the card can be verified. Each site then creates one part of the key to be agreed upon, and a test pattern for that key part. The test pattern is written to the site's own smart card in the second data record. The cards are exchanged, and the received cards are tested for authenticity using the published test patterns. Once accepted as genuine, the test pattern for the key part of the other site is read and stored. The key part previously generated is written onto the first data record of the received card. The cards are exchanged again. The key part is read at the home site of the card. The key part is verified for authenticity against the stored test pattern which was received earlier. Each site then combines the received key part with the locally created key part and they now share a common key.
Patent GB-2266200-A (GB)
Title: Fusible link
Inventor: KUDO TOSHIHARU
IPC: H01H85/56
Filed: 1993-03-10
Abstract: A fuse element 12 has a pair of connecting plates 14, a fusible portion 16 and engagement devices 18. A housing 11 (Figure 3) has a stepped portion to receive the engagement device 18 and thereby secure the element and a flange 26 against which the projection 19 abuts to locate the element. Since the connecting plates 14 are imperforate they do not overheat at excessive currents, unlike prior art plates, and in consequence there is no excessive heat to discolour and deform the housing walls. Deformation of the walls can prevent removal of the housing when a fuse has to be replaced. <IMAGE>

Patent GB-931301-A (GB)
IPC: B66B1/18
Abstract: 931,301. Lift control systems. EXPRESS LIFT CO. Ltd. Jan. 9, 1962 [Jan. 26, 1961], No. 3090/61. Drawings to Specification. Class 78 (3). In a multi-car lift system, the landing call buttons and associated relays are divided into groups or zones and means are provided for comparing the time intervals for which the groups have had calls registered within them and for despatching an available car from the floor at which it becomes available to answer first a call in the group having a predetermined time interval relative to the time intervals of the other groups. In the described embodiment, closure of a landing call button energizes the corresponding zone relay which causes further relays to be operated after time intervals of ten, fifteen, twenty ... sixty seconds. When a car becomes available, a relay is operated to energize a zone relay for the zone with the longest time interval causing the car to be despatched to that zone. If no zone has a ten-second time interval, the car is sent to a zone with outstanding calls in a predetermined priority order. If more than one car is available, the car nearest the lowest up-call or highest down-call in the selected zone is despatched. If it is required that one zone should have priority over the other zones, it is arranged that the time interval relays are operated after shorter time intervals of, for example, eight, twelve, sixteen seconds instead of ten, fifteen, twenty seconds. The system may be arranged so that a car, when allocated to a zone, answers calls within that zone and then continues to answer all calls ahead of it.

Title: Electrospraying method for mass spectrometric analysis
Inventor: FRANZEN JOCHEN
IPC: G01N30/72
Filed: 1995-03-08
Abstract: A method of analyzing analyte ions in a liquid using a spectrometer incorporating an ion trap 12, uses a capillary nozzle 2 adjacent an inlet aperture 6 for the ion trap. The liquid is electrosprayed from the capillary nozzle 2 by generating an electric field at the nozzle to ionise the said analyte and produce a beam of charged spray particles, and the beam of charged particles is injected into the ion trap 12 through the inlet aperture 6. The pressure within the capillary is such that flow of the liquid through the capillary occurs only in the presence of the said electric field, and flow of ions into the ion trap is controlled by varying the electric field from supply 15. … <IMAGE> …

IPC: F15B1/12
Filed: 1995-06-15
Abstract: A pressurised water reservoir tank, preferably made of plastics material, has a cap (2) and a tank member (1) that are connected together. The bottom of a flexible diaphragm (4) is fixed to the periphery of the cap (2) by a locking ring (3) having a flange which is firmly engaged with the periphery at the connection of the cap (2) and the tank member (1) by melting, through abrasion, a plastic wedged section and allowing it to cool so that the diaphragm (4) can be firmly retained in place.

Title: Ostomy coupling
Inventor: STEER PETER LESLIE
IPC: A61F5/448
Filed: 1995-08-30
Abstract: An ostomy coupling has first and second coupling members (10,30 Fig 8) which are held together by a springy flexible split locking ring (20,Fig 3). A plurality of tabs (26), arranged, e.g. symetrically, on the limbs of the locking ring (20) can be withdrawn generally radially outwardly by movement of the locking ring (20) to permit separation of the two coupling members (10, 30). The movement of the locking ring (20) which causes withdrawal of the tabs (26) may be a vertically upward movement of the ring, or a vertically downward movement. The movement of the locking ring (20) which causes withdrawal of the tabs (26) alternatively may be a deformation of the ring in opposed horizontal directions. Preferably, however, the movement of the locking ring (20) which causes a withdrawal of the tabs (26) is a rotational movement relative to the second coupling member (30).

Title: A digital oscillator
Inventor: DENT PETER RICHARD
IPC: H04L27/233
Filed: 1993-03-01
Abstract: A digital oscillator 5 produces alternately samples of two different phases of a periodic waveform. The oscillator comprises an accumulator for storing a phase signal. An adder alternately adds to the phase stored in the accumulator an increment to change the phase stored from that of the first phase of the waveform to that of the second and an increment to change the stored phase from that of the second phase of the waveform to that of the first plus an amount to advance the first phase. The phase values are applied to a read only memory storing samples of the waveform to reproduce alternately the samples of the two phases of the waveform. The use of the oscillator in transmitter and receiver circuits is disclosed.
