Patent GB-2184596-A (GB)
Title: Laser diode pumped solid state laser
Inventor: BAER THOMAS MICHAEL
IPC: H01S3/08
Filed: 1986-12-19
Abstract: A neodymium or other rare earth doped solid state laser (11) is pumped by a match high efficiency laser diode, resulting in a compact, high efficiency and long lifetime laser assembly. Output is in the near infra-red range, but can be converted to the visible spectrum by an intra-cavity frequency doubler (16), such as a doubling crystal, which may be a KTP crystal, placed at an optimum location in the laser cavity. Polarization of the beam may be achieved simply by stressing (by screw 42) a non-birefringent laser rod, prior to frequency doubling, or by using a birefringent material such as Nd:YLF for the rod. An amplitude noise suppression etalon (52) may also be placed at an optimum position in the laser cavity; alternatively a ring cavity or pair of quarter wave plates can be used. A folded cavity configuration produces a pair of beam waists in the cavity. Pulsed operation can be produced by means of a Q-switch (66). <IMAGE>

Title: Fishbait
Inventor: LINDGARD KNUD
IPC: A01K97/04
Filed: 1987-10-22
Abstract: A bait consisting of a bread crumb containing a reticulate and resilient web of plastic monofilaments which act synergistically with the gluten of the broad crumb to form a resilient structure, which, while still permeable by water is practically impervious to dissolution in water unless masticated. The buoyancy of the bait may be influenced by the application of pressure, or the ommission thereof, to release gas bubbles trapped in the bait because of the resilient structure.

Title: Blood sample monitoring device
Inventor: KENT MARTIN ROBERT
IPC: G01N21/86
Filed: 1988-04-05
Abstract: The device 10 is intended to measure the glucose level in a blood sample, by measuring the change in colour of a sensitised strip 11 on which a sample has been applied, the device 10 having a housing 12, and an input station 13 for receiving the sensitised strip 11 with a sample portion 14 on which a sample is applied. A light source (17, Fig 2, not shown) is arranged in the housing 12 to direct an optical beam towards the sample portion 14, and an electro-optic receiver (18) in the housing 12 receives the beam reflected from the sample portion 14 and generates an electrical signal representative of the proportion of the predetermined component in the blood sample. A driving device (19) receives the signal from the electro-optic receiver, and operates a bar graph type display device 22. The monitoring device will be particularly suitable for use by diabetics in order to give a clear visual indication of glucose level in a blood sample. <IMAGE>
Patent GB-2210123-A (GB)
Title: Pipe fitting assembly
Inventor: HARRIS WAYNE ALBERT
IPC: F16L19/12
Filed: 1988-09-23
Abstract: A pipe fitting assembly comprises a slit-type collet (16) clamped between a body (11) and a nut (12). A sealing ring (15) is compressed between a sleeve portion (17) of the collet and a groove (30) in the body (11) and urged into sealing engagement with the plastics pipe (19). The collet (16) has barbed fingers (22) which are urged inwardly by a tapered surface (26) in the nut (12). A longitudinal gap (31) in the collet (16) may close before the sealing ring (15) has fully entered its groove (30) but the barbed fingers (22) are not urged against the pipe until after the nut (12) has been tightened sufficiently to press the sealing ring (15) into position. An improved seal is thereby obtained, even at minimum tolerance for the pipe diameter and when the pipe end is slightly out-of-round. <IMAGE>

Title: Heated nebulizer system
Inventor: MILLER KENNETH G
IPC: A61M16/12
Filed: 1988-10-04
Abstract: A nebulizer system for producing a humidified and heated breathing gas to be inhaled by a patient undergoing inhalation therapy, includes a nebulizer module 12 and a heater module 14 detachably connected to each other.

Patent GB-2245806-A (GB)
Title: Generating an image
Inventor: WINSER PAUL ANTHONY
IPC: G06T15/50
Filed: 1990-06-29
Abstract: Apparatus for generating an image of objects in a three dimensional space for display on a two dimensional regular pixel array includes means for anti-alias filtering which causes multiple rendition E, E', E" of the image with each rendition offset by a fraction of the pixel size with respect to the previous rendition. Image primitives P are rendered by a scan line algorithm using a linked active polygon list and a deleted polygon list to enable vertical offsets to be effected. The deleted polygon list stores primitives which would not be effective for a given line but for the offset to enable anti-alias filtering. These polygons would not normally be available for processing when using the scan line algorithm. <IMAGE>
Patent GB-2235322-A (GB)
Title: Voice-operated service
Inventor: CAMERON IAN ROSS
IPC: H04M3/493
Filed: 1990-10-25
Abstract: In a telephone banking service, initial log-on (before service has identified the user) must use speaker-independent recognition (i.e. the speech recognizer (2) operates in accordance with a word template drawn from the population at large). Once the speaker is identified, the recognizer (2) employs a template specific to each individual speaker; this is much more accurate. The invention assists the log-on procedure by assigning each speaker a password consisting of a string of, for example, 5 digits which uniquely identify him, measuring the clarity with which the speaker recites each digit, compared to the standard template, and selecting his password from only those digits which he can clearly pronounce. The first digit may be used to indicate whether the speaker is male or female, and thereafter a respective "male" or "female" standard template may be employed.

Inventor: GOOM STEPHEN WILLIAM
IPC: G01N21/35
Filed: 1992-06-18
Abstract: An infra red gas detector has as its gas sample chamber, a porous hollow tube 4. The sample gas or air can freely diffuse or permeate through the walls of the tube and gain access to the inner chamber where infra red absorption can take place. The internal tube walls additionally act as a light guide ensuring that maximum infra red light reaches detectors. The tube 4 may be constructed from a number of different materials including sintered metal, ceramic, plastics or other synthetic materials, and may be parallel, tapered, arcuate, coiled or T-shaped. The infra red source 5 includes a modulator, and radiation reaches a detector 2 by way of a filter 3 set to a frequency corresponding to an absorption frequency of the gas to be detected. A second filter and detector are provided as references to compensate for physical variations. <IMAGE>
