Filed: 1973-01-03
Abstract: 1381083 Inflatable bags ALLIED CHEMICAL CORP 3 Jan 1973 [11 Jan 1972] 437/73 Heading B7B Vehicle safety apparatus comprises a gas source 34 having a gas containing portion 36 and a gas generating portion 32, a plurality of gas generating charges 28, 30 disposed within the gas generating portion, means 24, 26 for igniting the charges 28, 30 upon receipt of an electrical current and means for permitting gas developed from the charges 28, 30 to flow into the gas containing portion 36 with gas releasing means 40 connected to the portion 36 for permitting the pressurized gas and the generated gas to flow into an inflatable bag 31. In operation, forces resulting on vehicle impact displace a roller 87, Fig. 2, of an impact detector 14 against a first preselected resisting force determined by an electroconductive band 90 of stainless steel or gold plated copper until the band 90 contacts conductive element 92. An electric current is then transmitted from power source 12 to heat a bridge wire 84 which actuates detonator 82 to dislodge plug 80. Pressurized gas 38 then flows into bag 31. With a greater vehicle impact force roller 96, Fig. 3, of control element 16 is displaced against a greater resisting force determined by band 100 which contacts switch means 46 and resistance element 102 for electric current to be transmitted during a controlled time interval from source 12 via a transmission circuit 20 to bridge wire 60. Squib 54 then ignites a gas generating charge 28, the barrier 50 ruptures and gas flows through diffuser 76, portion 36 and into bag 31. Input forces of greater magnitude will similarly actuate control element 18 so that current is transmitted during a controlled time interval for actuating charge 30. As the roller 96 is displaced the band 100 is brought into contact with a variable portion of resistance element 102 so that the time interval of travel of current varies inversely with the vehicle impact force. The bag 31 preferably has a porous portion 144 for the bag to collapse at a preselected rate. Means is thereby provided for varying the gas generating charges ignited in direct proportion to the impact velocity.

Title: Improvements in the construction of direct current dynamo electric machines
IPC: H02K23/40
Filed: 1922-01-10
Abstract: 196,048. Newton, F., and Newton Bros. (Derby), Ltd. Jan. 10, 1922. Field magnets; brush-holders; casings; machines with two armatures; terminals and accessories, arrangement on machine.-In a lightweight continuous-current dynamo the field coils surround the armature and are surrounded by a field structure of stampings, as shown in Fig. 5, having a flat exterior surface nearly tangential to the pole face at its centre so that the coresection decreases towards the centre and distortion of the flux is impeded. The form illustrated is a machine for aircraft wireless having a highvoltage armature 4 for the valve plate and a lowvoltage armature 5 on the same shaft for excitation and for the valve-filament current. The light non-magnetic casing 1, which is enclosed to streamline form by end caps, is continued below the machine to form a chamber, closed by a plate 18, for the condensers 15, 16. Ribs 14 in the casing are bored to support the circular end and intermediate laminae 13, of the shape shown in Fig. 6, between which the flat-surfaced laminae 2 are secured by members 20 which are fastened to the laminae 13 by their outwardlyturned edges. The pile of laminae 2 may be twisted through the arc of an armature tooth and the members 20 may lie on the twisted flat surfaces. This twisting reduces ripples in the machine voltage, and the armature slots may be nearly closed for the same purpose. The field coils are curved, as at 12, Fig. 1, to allow insertion of the armature. One brush-holder of the generator 4 is of metal to give a connection to the frame and the other, which is insulated, is brought out to the packed insulated plug-contact 22 below the machine. The terminals of the other machine are brought out to sockets in an insulating-block 24 adapted to receive the loosely mounted pins 26 of a plug 19. This consists of a metal cap containing an ebonite cup 25. The pins pass loosely through the cup, their heads being sunk in recesses, so that they can easily adapt themselves to the sockets. The movement of the pins is limited by a coned ebonite ring 27. A metal cap 28, screwed to the plug 19, may be used for making a water-tight taped joint on to the cable which also prevents tension on the cable from affecting the pin-contacts.

Abstract: 387,489. Plug cocks. NEWTON, R. B., 16, Bloemfontein Road, Shepherd's Bush, London. Jan. 12, 1932, No. 901. [Class 135.] Handles.-Relates to a plug cock in which the stem, such as 10, Fig. 1, is surrounded by a guard barrel, as 16, having its upper opening inwardly flanged and is formed of a non-circular cross section to co-operate with a similarly-shaped socket in a removable key, as 30. In such an arrangement the stem 10 is made cylindrical with a single longitudinal groove 14 and the key 30 is of cylindrical tubular form with an internal projection or rib 32 for engagement with the groove 14 in the stem. The outer diameter of the key 30, Fig. 1, is a close fit within the inturned flange 26 and a projection 34 is provided which can pass through a notch 28 in the flange as the rib 32 is engaging the groove 14 in the stem. This ensures that the particular key 30 must be used to obtain operation since another key with the projections 32, 34 angularly displaced could not be inserted. To provide for operation of the cock when it is in an inaccessible position, such as behind the dashboard of a car, an extension tube 40, Fig. 5, is fitted to the guard barrel and the plug stem is lengthened, as shown ; the upper end of the tubular extension and the stem are formed or fitted, as shown, similarly to Fig. 1, to provide similarly for cooperation with the removable key.

In apparatus for producing packages of parallel build by the ring and traveller method, the spindle speed is gradually decreased as the winding-on diameter increases throughout the build, the reduction being preferably in inverse ratio to the increase in diameter of the package. In this way, the traveller speed can be kept constant at a maximum consistent with avoiding wearing and burning of the traveller, and in draw-twisting large packages of highlytwisted material may be produced. As shown, the invention is applied to a draw twister in which the package is built in parallel layers. A motor 15 is connected (a) to a sprocket 17 driving a shaft 171 geared to a series of drawrolls 10; (b) to a sprocket 181 of a reduction gear-box 18 of which the output shaft 182, through a worm 183 drives the builder-cam 19; and (c) to the input shaft 211 of a variablespeed unit 21, of which the control shaft 213 is driven from the shaft 182 and the output shaft is connected to a shaft 22 from which the spindles are driven. The control shaft 213 may alternatively be driven by a motor rotated intermittently as each traverse is completed.
