Title: Storage heater
Inventor: CHIDLOW ERNEST
IPC: F24H9/20
Filed: 1993-03-26
Abstract: A storage heater has a vertical baffle 22 dividing an inlet passage from a heat storage body 13. Several openings are formed in the baffle at respective different heights and these are controlled by respective valves 26, 27. The valves are biased to closed conditions but each valve opens when the pressure differential imposed by fan 33 across the valve attains a predetermined value. Opening of these valves reduces the resistance to flow of air through the heat storage body. Fan 33 and valve 35 are actuated in response to the temperature of air discharged from the heater casing. When the body 13 is hot valve 35 is open, and the air discharged is a mixture of a large amount from bypass 34 and a smaller amount from the lower channels of body 13. As body 13 cools valve 35 closes, and the air discharged includes an increasing portion which has travelled through ducts 16 - 18 in body 13. <IMAGE>

Title: Aerosol sampler.
Inventor: BOOKER DAVID RICHARD
IPC: G01N1/22
Filed: 1993-08-11
Abstract: An aerosol sampler (10) comprises at least one U-tube (16) whose ends are fixed to a support (14), and through which the aerosol is caused to flow. Means (40) are provided to set the tube vibrating, and to measure its resonant frequency. The bend of the U-tube (16) acts as an impactor so aerosol particles larger than a cut-off size are trapped, causing a change in the measured frequency. A sampler (10) may include a number of such U-tubes (16 - 24) in series, with steadily decreasing cut-off sizes, so the aerosol particulate size distribution can be determined. <IMAGE>

Title: Method for investigating digital sampling effects
Inventor: HOLNESS PETER J
IPC: H03M1/12
Filed: 1993-10-15
Abstract: A method which simulates sampling errors utilises a calculator (1) for creating a sequence of y values which form the result of a generator equation y=f(P) for a discrete number of P values over a pre-determined range. By altering the number of equally-spaced P values over the range the effect of increasing or decreasing a sampling rate is achieved. The result is represented in a graphical form by an X-Y plotter (3). <IMAGE>

Title: Female urinal
Inventor: BUCHANAN SUZANNE ELENA
IPC: A61F5/455
Filed: 1994-09-14
Abstract: A portable hand-held urinal for use by a female in a squatting position is disclosed. The urinal comprises a cup 1 with a rear ridge 4 and a discharge tube 2. In use, the discharge tube depends upwardly with respect to the cup. This means that a smaller access opening in clothing is required for the introduction of the urinal and that the flow of urine can be observed by the user. The rear ridge prevents possible overflow of urine during use due to backflow. The urinal is intended for use by females in remote environments, eg when skiing. <IMAGE>

Title: Sealing of cable crutch
Inventor: WEATHERLEY JOHN WILLIAM
IPC: H02G15/105
Filed: 1992-03-24
Abstract: A multi-core electric power cable (42, 44) is sealed, against insulating oil or water for example, in the region where the cores (52, 54) emerge from the cable jacket (46) at a joint (40) of the cable. The sealing is achieved by a mastic (56) applied to the crutch region of the cable (42, 44) and by an enveloping compression sleeve (58) therearound. The sleeve is heat shrinkable or revolvable. Two such cables are jointed using similar sleeves (64) to provide primary insulation and optionally screening around connections of the core conductors. The cores are bundled together in a copper mesh (66) that contacts a perforated metal shield (68) that provides earth continuity across the joint. A pair of plastic half shells (74) is sealed around the joint, and filled with curable resin (76) to provide mechanical protection. The shield (68), cores and shells (74) can be spaced by multilimbed members. A reduced length shell can be sealed to the cables by heat shrinkable tubing. <IMAGE>

Title: Synthetic peptides for use as epitopes specific for HIV
Inventor: ARNOLD BETH A
IPC: A61K39/00
Filed: 1995-10-10
Abstract: There are disclosed selected principal neutralization synthetic epitopes which bind the Human Immunodeficiency Virus (HIV) neutralising antibody 19b which antibody is specific for the HIV gp120. The epitopes are identified from phage epitope libraries using the antibody. The epitopes can be conjugated to immunological carriers such as the outer membrane proteosome complex of Noisseria or an immuno-enhancer sequence such as Hepatitis B core. The conjugate may comprise one epitope sequence or multiple sequences. The conjugates are useful for vaccination against Acquired Immune Deficiency Syndrome (AIDS) or Aids-Related Complex as well as in the production of other HIV-specific broadly neutralizing antibodies for passive immunity against AIDS or Aids-Related complex.
Patent GB-2307803-A (GB)
Title: Static VAR compensator with capacitor energy dissipation
Inventor: GRIFFITHS PETER THOMAS
IPC: H02J3/18
Filed: 1995-11-28
Abstract: The capacitors 33, 43, 53 of a polyphase VAR compensator are connected to transformer means 21 and to energy dissipation means 34, 44, 54 such that when the capacitors are switched out of circuit in sequence by switches 35, 45, 55, a residual charge on the capacitors is reduced by transfer of energy between the capacitors and the energy dissipation means via the transformer means 21. This prevents the switches 35, 45, 55, particularly thyristors, from having to hold off large voltages (sum of capacitor and phase voltages) in their open state. The energy dissipation means may include resistors 34, 44, 54, but these may be omitted when the transformer windings have adequate resistance. The transformer means 21 may be three single phase transformers with respective first windings 31, 41, 51 across the capacitors 33, 43, 53, and series connected second windings 32, 42, 52. Alternatively, one three-phase transformer has three core limbs carrying respective first and second windings; a similar arrangement omits the second windings. If one limb of a delta connected compensator is connected in the opposite sense to the other two (Fig.8), a single phase transformer may have one winding (71) connected across two of the capacitors in series and a second winding across the other capacitor. Energy transfer may be assisted by saturation of the transformer core or cores. The capacitors may exhibit oscillatory discharge at a frequency near the supply frequency if the transformers have very low reactance.

Title: Buffers
Inventor: PAGE RONALD CECIL
IPC: F16F9/06
Filed: 1996-04-29
Abstract: A railway side buffer comprises a telescopic casing consisting of a cylinder (11) which is closed at its outer end by a buffer plate (10) and which slides within a closed ended cylindrical casing part (12). The end of the cylinder (11) within the casing part (12) is closed by a ring (14). A plunger comprises a rod (15) which abuts the end wall of the casing part (12) and slides within the bore of the ring (14), and a piston head (18) which slides within the bore (17) of the cylinder (11). The cylinder space (26) between the piston head (18) and the buffer plate (10) is a compression chamber. The annular cylinder space (25) between the piston head (18) and the ring (14) is a reservoir within an annular gas-filled space (32). The liquid in the reservoir and the gas are in direct contact. A spring closed ring valve (21) on the piston rod (15) allows flow from the compression chamber (26) to the reservoir (25), damping that flow, and prevents flow in the reverse direction.

Title: Testing change in pressure gradient across a membrane
Inventor: STEPHEN RICHARD OWEN
IPC: A61B5/12
Filed: 1996-06-27
Abstract: There is disclosed a method and apparatus for sensing a change in pressure gradient across a membrane comprising firstly directing an acoustic stimulus at the membrane subject to the pressure gradient, the tension of the membrane being affected by the pressure gradient across it, and secondly detecting the reflection of the stimulus from the membrane, repeating the two steps at least once more, and comparing the detected reflections. In particular, the method and apparatus can be used for sensing changes in pressure gradients across a tympanic membrane separating the middle and outer ear. A probe for insertion in the outer ear containing an acoustic stimulus emitter 10, sound detector 11 and pressure vent, is used. By sensing changes in pressure gradient across the tympanic membrane, the effectiveness of the Eustachian tube in equalising the pressure gradient can be monitored. The technique therefore provides a quick and convenient test of Eustachian tube functionality.
