Title: Bitumen felt
Inventor: HOLBEK JOHN
IPC: D06N5/00
Filed: 1997-07-23
Abstract: The invention concerns bitumen felt composed of several bitumen layers comprising a support layer (1) and at least two bitumen layers (2, 3.1) applied one on top of the other to a first side of the support layer. On the second side of the support layer (1), a strip (3.2) of a bitumen layer is applied along the longitudinal edge of the felt, the width (b) of the strip being smaller than the width (B) of the felt. The strip is made of the same bitumen material as the outer bitumen layer (3.1) on the first side of the support layer (1). Another bitumen layer (4) which is adjacent to the bitumen strip (3.2) applied along the longitudinal edge is applied to the second side of the support layer (1). This additional layer is composed of a different bitumen material to the bitumen strip (3.2) and extends from the strip to the other longitudinal edge of the felt. This design enables the overlap areas to be particularly well sealed when laying the bitumen felts.

Filed: 1998-01-29
Abstract: La présente invention concerne un circuit imprimé (10) comprenant un support flexible (11) sur lequel adhère un revêtement de matériau conducteur (12) formé par des tracés (13). Un adhésif (14) maintient le matériau conducteur en place.

Title: Apparatus for capturing light energy
Inventor: SUGINOBU KOH
IPC: F24S23/00
Filed: 1999-12-14
Abstract: An apparatus for capturing solar radiation of tracking type including a matrix array of a number of light receptors is disclosed. A first set of four shafts are disposed parallel to each other and parallel to a floor surface on which the apparatus is installed. A second set of four shafts are mounted on each shaft in the first set, and four light receptors per one shaft in the second set including 4×4 equal to 16 shafts are supported, thus providing a total of 64 light receptors. Each light receptor internally contains a mirror having four sections, and four parabolic mirrors of a reduced diameter which reflect light reflected by respective sections to the center of each section.  Where the light receptors constitute a light collector which condenses and projects solar radiation into optical fibres, a conical opening having a reflecting surface is defined centrally in each section, with a light receiving end face of an optical fibre disposed at the bottom thereof. Where the light receptors constitute a heat collector which converts the solar radiation into heat to heat a heat exchange fluid, a photo-thermal conversion surface is formed in the form of a conical opening centrally in each section, with a channel for a heat exchange fluid disposed therearound.

Title: Rebroadcasting communication system
Inventor: BARCLAY MICHAEL JOHN
IPC: H04N7/173
Filed: 1998-07-07
Abstract: A communication system is provided which can provide a broadband communications link into a number of homes and business. The communication system comprises a base station for broadcasting communications in the microwave frequency to a number of user stations within a cell. Some of the user stations can communicate directly with the base station while others communicate with the base station via intermediate user stations. To achieve this and to provide robustness for changing channel characteristics, each user station is adapted to re-transmit the communications which it receives. Most user stations and the base station therefore receive multipath signals and an orthogonol frequency division multiplexing technique is used to overcome the problems caused by the reception of multipath signals.

Title: Jump start system for vehicles having different operating voltages
Inventor: HOUGH BARRY MICHAEL
IPC: F02N11/14
Filed: 2000-02-08
Abstract: Jump start structure and method particularly useful for a battery-start vehicle for starting the vehicle or quick charging the battery from a separate source which may have an operating voltage substantially higher than the battery voltage. A starting system operating at a first voltage, for example twelve volts, is connected to a separate source of higher voltage, such as twenty-four volts, through a jumper cable. In one embodiment, a manual switch on the vehicle with the discharged battery must be operated simultaneously with the key switch to start the engine. In another embodiment, an inexpensive control circuit including a normally closed relay located on the vehicle connects the separate source with the discharged battery when a jumper cable from the source is plugged into the vehicle. Once the discharged battery receives sufficient charge, the relay activates to open the circuit between the separate source and the vehicle battery. The normally closed relay facilitates use of the vehicle for jump starting another vehicle.

Abstract: A method and assembly (kit) are provided for use by propane tank servic e personnel to detect escaping gas in propane tank systems. The standard connection between the regulator and tank service valve is replaced with a permanent valve assembly including a main connection between the regulator and valve and a valve unit  disposed in a branch connection of the valve assembly. A separate pressure gauge is individually assigned to tank service personnel and adapted to be carried by such personn el in testing the pressure in the propane tank. The pressure gauge is affixed, e.g., throu gh a hose, to a valve unit connector including an actuator, i.e., a valve stem operator, for  actuating the valve unit. When the pressure gauge is connected to the valve unit, the latt er is actuated to provide an immediate reading of the tank pressure. A determination is mad e from this reading whether the tank is out of gas, and if the tank is out of gas, the service valve is turned on, gas introduced, the service valve turned off and a further pressu re check made to determine whether gas is leaking. In one embodiment, the valve unit comprises a saddle valve directly connected to the main connection over a drilled hole i n the latter. In another embodiment, a manifold block, which includes a through bore and an orthogonal, communicating bore, mounts the valve unit.
