Title: Gas valves
Inventor: ROBERTS PETER DEREK
IPC: F16K31/00
Filed: 1987-05-15
Abstract: A gas valve has a closure member 16 which is held on its seat by a spring 18, and displacement of the valve is caused by an electric resistance heater 30. In the preferred embodiment heater 30 raises the temperature of a coil 26 of shape memory effect brass: as the temperature passes a transition point the coil expands to displace the closure member to the open position. The heater may alternatively cause expansion of a working medium which may be a liquid which undergoes a phase change or simply be a fluid which is expanded by the heat. <IMAGE>

Title: Structures for deriving energy from natural sources
Inventor: FARRELL JOHN PATRICK
IPC: F03G3/00
Filed: 1987-10-13
Abstract: Energy derived from tidal or river flow energy units 17, solar cells 15 and wind driven devices 16, is fed to a control centre 14 and may be used to drive a block 10 up guides 11 to store the energy. Subsequent lowering of the block can be used to release energy. The block may comprise a container which may be filled with rainwater when in its raised position and drained in its lowered position. The block may be raised by drive motors located thereon and driving pinions engaging racks on the slope. The block 10 may be large enough to grow crops, graze livestock, and/or provide a recreation park, tourist attraction and hotel. Another aspect of the invention (Fig. 5) provides an underground structure 20, (such as a nuclear shelter) the structure being encased in puddle clay 26, to seal the structure and prevent water or any other liquid from entering if cracks in the structure should occur. An accommodation chamber 20 is connected to an access shaft 22 via a tunnel 21. <IMAGE>

Title: Device for protecting turntable shaft of microwave oven
Inventor: LEE EON HO
IPC: H05B6/80
Filed: 1987-10-28
Abstract: A device for protecting the turntable shaft of a microwave oven, so as to prevent a turntable shaft 3 made out of resinous material from fusing during the operation of the microwave oven. A protective plate 4 is mounted on the lower surface of the turntable in such a manner as to form a supplementary cavity 6 in which the impedance is a maximum at the inlet, and a choke cavity 5 in which the impedance is a minimum at the inlet, the dimensions of both the cavities being preferably 114 and 112 of a wavelength respectively so as to prevent the microwaves from becoming concentrated around and in the region of the shaft, thereby preventing or reducing the risk of the shaft becoming fused and making it possible to use a cheap resinous material for the shaft. <IMAGE>

Title: Joint for ducting
Inventor: HACKENBERG FRANZ WERNER
IPC: F16L17/10
Filed: 1988-01-13
Abstract: Rigid conduit ends of ventilation ducting 12, (212) and 14 (214) of synthetic plastics or resinous material are jointed in series, male-female fashion. An annular gap 28 (228) between the male and female portions is sealed by providing an expansible seal member 18 (218) in the gap and expanding it. In one embodiment, (Fig 4) the seal member 18 is in the form of a band secured along its edges to the female (outer) conduit end portion 14 and having a flexible elongate element 20 outwardly around it. Tightening of the elongate element around the male conduit end portion 12 expands the band 18 inwards and squeezes it against the outer periphery of the male conduit end portion 12 to effect sealing.   In an alternative embodiment (Fig 6) the seal member 218 is in the form of a flexible tube secured within the outer end portion 214 and capable of inflation by means of valve 220. The tube 218 is thus expanded inwards against the outer periphery of the male conduit end portion 212 to effect sealing. <IMAGE>

Title: Method of obtaining methanol
Inventor: ROZOVSKY ALEXANDR YAKOVLEVICH
IPC: C07C31/04
Filed: 1987-07-23
Abstract: A method of obtaining methanol consists in contacting a gas mix, containing carbon monoxide, carbon dioxide and hydrogen, with a copper-containing catalyst at a temperature of 190-290 DEG C and a pressure of 5-10 MPa in two stages. During the first stage the copper-containing catalyst is contacted with a gas mix containing 5-30 % by volume of carbon monoxide, 0.3-20 % by volume of carbon dioxide at a volume ratio between the carbon monoxide and the carbon dioxide of 0.25-87 and at a volume ratio between the hydrogen and the total of carbon oxides of 2-3.65. The first stage is carried out in one through-flow reactor or in a cascade of such reactors at a bulk speed of the initial gas mix of 4,500-100,000 h<-1>, thus obtaining, after the first stage, a gas mix containing carbon monoxide, carbon dioxide, methanol vapor and 0.02-1.38 % by volume of water vapor. The methanol and water vapors are removed from the gas mix and the remaining gas mix, which contains the carbon monoxide, the carbon dioxide and the hydrogen, is fed to the second stage which is carried out in a reactor at a bulk speed of 7,000-15,000 h<-1> thus obtaining, after the second stage, a mix containing the carbon monoxide, the carbon dioxide, the hydrogen and the methanol and water vapors, the methanol and water vapors being then removed from the gas mix.

Title: Refrigeration system
Inventor: ADAMSON PETER WILLIAM
IPC: F25B47/02
Filed: 1988-06-27
Abstract: This invention relates to a refrigeration system particularly for use in corrosive environment wherein exposed apparatus can deteriorate rapidly. The system is for drawing heat from a walled storage area, and comprises a refrigeration cycle in which the condenser 6 is disposed adjacent the inside face of a wall of said walled area. This arrangement allows heat exchange across the wall to the external environment, the condenser being insulated from the storage area. The compressor 14 is disposed within a housing which is closed to the ambient environment and kept cool by its own evaporator 46. A heat exchanger 62, which accumulates heat from the compressed discharge fluid during the refrigeration cycle, gives out heat during the defrost cycle, which heat together with particular defrost discharge route for compressed discharge fluid provides a rapid defrost cycle. <IMAGE>

Title: Adjustable pillar loop for seat belts
Inventor: STONEFROST MARK
IPC: B60R22/20
Filed: 1989-05-05
Abstract: The pillar loop 14 is secured to an assembly 4 slidably mounted on a rail 1 mountable in a vertical position adjacent the shoulder of a person sitting in a motor car.

Title: Internal composite layer for a multilayer circuit board
Inventor: TAKANO HIDEKAZU
IPC: H05K3/46
Filed: 1993-02-24
Abstract: An internal composite layer for a multilayer circuit board, which is composed of an electrically insulating substrate with a copper layer formed thereon and a film of a coupling agent covering the copper layer is fabricated by treatment with a base such as sodium or potassium hydroxide or sodium methylate or sodium ethylate or lithium ethylate or the base and an accelerating agent to supply hydroxyl groups to a surface thereof. Subsequently, the treated copper layer is coated with the coupling agent, e.g., a silane, titanate or zirconate coupling agent. The coupling agent is chemically bonded to the treated copper layer by the reaction of the hydroxyl groups with the coupling agent, so that an adhesion strength between the copper layer and the coupling agent is increased. In addition, since it is not necessary for forming a copper oxide layer in the surface of the copper layer, the internal composite layer shows excellent acid resistance without causing a pink-ring which usually occur around a through-hole plating.
