Filed: 1968-10-17
Abstract: 1,178,088. Electric couplings. BURNDY CORP. 17 Oct., 1968 [23 Oct., 1967], No. 49215/68. Heading H2E. An electrical connector for an insulated cable 52 having a homogeneous core 56 of a soft metal such as sodium has an internally cylindrical body portion 10 which houses, at least partially, a contact member 14 having a slidable piston portion comprising a ring element 20 and a sealing ring 22, and a contact portion 32 beyond the piston. The cylinder is sealed at its other end by a sealing ring 26 in a reduced diameter portion 28, so that when hydraulic fluid is admitted through an inlet 44, the piston is forced along the chamber, causing the pointed contact portion 32 to penetrate the cable core 56. Once hydraulic material is present, it and the sealing rings prevent the access of air, water, and other corrosive agents. The connector body 10 has an internal selftapping thread, which enables the body to be screwed into the outer surface of the cable jacket 54, which may be of polyethylene. The contact tail portion 40 may be of any design suited for the attachment of further conductors by conventional means. The piston portion 30 held in position by a snap-ring 18 which cooperates with a groove 38 in the contact member 14, a similar ring 66 co-operating with another groove 70 to hold the contact member in the advance position, this being further facilitated by the inlet preferably having a one-way ball valve (48, Fig. 1, not shown) to prevent the escape of hydraulic fluid. Bypasses (62) and vents 64 permit any excess fluid to escape, and also indicate when penetration is complete. Hydraulic fluids suitable include greases, " liquid rubbers," conventional hydraulic pressure fluids, and hardenable materials, such as epoxy resins, which set after being pumped in, so serving additionally to hold the contact in the inserted position. The outer body surface 10 may be provided with flats so that a spanner may be used to screw the connector to the cable insulation.

Title: Vehicle occupant restraint system
IPC: B60R21/263
Filed: 1972-10-26
Abstract: 1393126 Vehicular safety devices GENERAL MOTORS CORP 26 Oct 1972 [3 Nov 1971] 49469/72 Heading B7B [Also in Divisions F4 and F1] In a vehicle crash restraint system including a cushion inflatable from a fluid pressure source, means are provided for inflating the bag at different rates during high and low impact crashes. The gas source comprises a container 10 filled with a pressurized gas and enclosing a gas generator 12, the container being sealed by a diaphragm 18. The gas generator includes ignition squibs 14 and 16 respectively of the delay and non-delay action type I impact sensors 22, for detecting crash impact above a predetermined minimum, are connected in series with the delayed action squib 14 and diaphragm rupturing charges 20. On low impact crash the sensors 22 actuate charges 20 to allow the pressurized gas to escape and begin inflation of the cushion immediately, however, the gas generator is not actuated until some time later because of the action of the delayed action squib. A further impact sensor 28 is connected in series with one of the sensors 22 and with the non-delayed action squib 16, the sensor 28 being actuated on crash impact above a predetermined maximum. On high impact crash both the sensors 22 and 28 are actuated so that the squib 16 and hence the gas generator 12 are fired simultaneously with the charges 20. This results in the pressurized gas and the gas generated on ignition of the generator 12 being supplied to the gas cushion together immediately following impact. If multiple impact occurs i.e. a low impact followed by a high impact, the squib 16 may fire the generator 12 before squib 14 depending on the interval between impacts. Each squib includes a bridge wire for firing ignition material which in turn ignites an intermediate charge material which in turn ignites an output charge. These materials are layered within a cylindiical housing and ignition of the output charge ruptures the housing to fire surrounding material which generates gases. The delayed action squib includes a delay charge layer, which burns at a controlled rate, prior to the output charge layer.
