Title: Firefighter's garments having minimum weight and excellent protective qualities
Inventor: GRILLIOT WILLIAM L
IPC: B32B3/28
Filed: 1989-10-19
Abstract: A firefighter's garment as disclosed herein may be a coat or trousers or a vest.  The garment has an outer layer, an intermediate layer, and an inner layer. A spacer element or elements are positioned between two of the layers of the garment.  The spacer element or elements in the firefighter's garment establish and maintain an air space or air spaces between the layers of the garment, even when localized pressure or weight is applied to portions of the garment.  Thus, the firefighter's garment has excellent heat insulation qualities without being heavy and/or bulky.  Thus, a firefighter wearing the garment is continually protected and is subject to minimum stress and is able to work more effectively than a firefighter wearing a firefighter's conventional garment.

Patent CA-2007939-A1 (CA)
Title: Tire-making method
Inventor: SCHMIDT OSKAR
IPC: B29D30/08
Filed: 1990-01-17
Abstract: Abstract of the Disclosure A tire is made by first fitting a pair of bead rings interconnected by reinforcement over a gas-pervious annular liner to form an annular core assembly and then inflating the core assembly by directly contacting same with a fluid to impart to the core assembly an inwardly open U-shaped section.  This U-section core assembly is then spacedly enclosed in a mold which is filled around the U-section core assembly with a hardenable elastomer which is hardened so it bonds to the reinforcement, rings, and liner to form a tire.  Finally the liner is deflated and the tire is demolded.  The liner has a pair of opposite end edges and is inflated by sequentially clamping each of the edges against a support so as to define between the liner and the support a pressurizable chamber, displacing one of the clamped edges toward the other so as to outwardly bow the liner, and introducing a fluid, typically air, into the chamber.  It is also possible to mount the rings in the mold and thereafter introduce the liner into the form for fitting it and the rings together.

Title: Test device for a bus with two pairs of conductors
Inventor: FIEAU JEAN-CLAUDE
IPC: G01R31/58
Filed: 1990-10-12
Abstract: ABSTRACT OF THE DISCLOSURE   The device checks the connection of the conducting wires of a bus such as a bus distributed in a local area network. It comprises two test modules to be connected to the terminations of the bus. The first module comprises a voltage source and detects electric discontinuities in the pairs of wires, and an abnormal crossing of two wires of one and other pair when the second termination is directly connected to terminating impedances of the bus. The second module signals a crossing of wire pairs and crossings of the wires within a pair.

Abstract: ABSTRACT         This invention relates to a load indicating member comprising a shank having at least one groove and an ultrasonic transducer means coupled to a load indicating member so that an ultrasonic wave is directed to the groove.  A surface can be formed adjacent to one longitudinal end of the shank and the ultrasonic transducer means can be coupled to this surface. Further, the ultrasonic transducer means can be coupled to this surface so that the ultrasonic wave is also directed to the other longitudinal end of the shank which is remote from the surface. The groove may be located on the shank at a predetermined distance from the surface for identification of the member. Moreover, the surface can have a recess, with the ultrasonic transducer means being located in the recess.  Advantageously, the groove can be an annular groove or the groove can be comprised of threads disposed on the shank.  Also, the shank can have two or more annular grooves.  These grooves can be located on the shank at a predetermined distance apart for identification of the load indicating member.  Preferably, the ultrasonic transducer means is a piezoelectric film transducer. Additionally, the preferred load indicating member is a fastener in accordance with the present invention.

Title: Surge voltage absorbing apparatus
Inventor: ITO TOSHIO
IPC: H01H37/52
Filed: 1991-02-01
Abstract: Abstract of the Disclosure A surge voltage absorbing apparatus has a transparent tube and a surge voltage absorbing element contained within the transparent tube to evolve heat upon discharge.  The surge voltage absorbing element has a pair of lead wires, one of which extends directly out of the tube and fixed in place.  A coil spring is disposed in the tube and has one end soldered to the corresponding lead wire of the surge voltage absorbing element and the other end portion extending out of the tube.  A discharge occurs in the surge voltage absorbing element upon the flow of a surge current by lighting, causing a solder spot to be broken to allow a terminal device to be open-circuited.  It is thus possible to protect the terminal device from a large surge current.

Title: Con-a-seal
Inventor: LUSSIER DONALD G
IPC: F16J15/00
Filed: 1991-04-17
Abstract: Abstract The effectiveness of rubbing seals is based on the fact that an elasticsealing element is pressed against the sealing surface with a certain pressure. A good quality of the sealing surface finish is necessary to keep the frictional and the wear of the sealing element as low as possible. The use of rubbing seals is limited by the maximum circumferential speed at the sealing surface which depends on the type of sealing. The sealing properties are better than with non-rubbing seals.
