Abstract: 1464613 Generating combustion products under pressure GENERAL MOTORS CORP 6 June 1974 [25 June 1973 (2) ] 25139/74 Heading F1L [ Also in Division F2] A combustion gas generator for inflation of a restraint cushion in a vehicle comprises a cylindrical pressure vessel 12 containing a fluid, e.g. argon, and a cartridge assembly 60 removably retained in a cylindrical casing 36 closed at one end by a rupturable wall 42. Cartridge assembly 60 comprises a plastics housing 62 containing a hollow cylindrical propellant 72 and at one end a metal plate 74 having a fluted outlet orifice 76. The other end of housing 62 is closed by an integral wall 66 having cylindrical bores 68, 70 containing respectively electrically fired squibs 78, 80. A metal ball 82 is also retained within bore 70. An igniter plug 90 electrically connected to squibs 78, 80 is carried by a seal plate 86 secured to wall 66, plate 86 having a chamfered edge 88. The latter is engaged by a circlip 92 which retains cartridge assembly 60 within casing 36 against the action of a biasing spring 96. When an impact sensor fires squibs 78, 80, the former ignites propellant 72 and the latter fires ball 82 into orifice 76 to restrict the flow area thereof and thus increase the burn rate. At a predetermined pressure, wall 42 ruptures causing a rod 50 to move rightwards within sleeve 54 rupturing the pressure vessel outlet 20. A mixture of combustion gases and argon thus flows through holes 28 in outlet member 22 and thence via manifold 32 and diffuser' 34 to inflate the restraint cushion. Casing 36 is designed to fail at groove 98 if the combustion pressure becomes excessive. An argon filling and bleed valve assembly, (136), Figs. 3, 4 (not shown) may be provided (see Division F2).

[Class 87 (i).] Bricks in a rank formed by cutting a clay clod by wires are separated apart outwards on both sides of the centre brick by overhead pallets only to facilitate drying. A clod of clay is passed laterally from a clod-supplying machine and cut to length by an operator. It is then pushed forward, by a mechanically - actuated back board, through wires which sever it into ten or more or less bricks, which are pushed on to a stationary table a. A series of pendent overhead plates c are supported on spaced guide bars c<1> which are supported in the frame f of the apparatus so as to be lowered by cams h and advanced by cams g. Pallets d are carried by the plates c so as to be capable of rising and falling movement relative thereto and are lowered by the cams h onto the individual bricks when a rank of bricks is in position. They may, if desired, be pressed downwards by springs. Overhead barrel cams i, mounted on the shaft i<l> which carries the cams g, h, and having throws increasing from the centre outwards in both directions, engage bowls j<1> of shanks which play in slots in the plates c to move the bricks in a rank outwards from the centre. The pallets d are then advanced by the cams g to advance the rank of bricks clear of a rank behind it. The spaced bricks are pushed by the succeeding rank of bricks into a tray ready for removal to the place where the spaced bricks are to be dried. These trays may be removably carried on supports so as to be moved forwards automatically by the driving mechanism for the separating apparatus. Specification 4308/02, [Class 87, Moulding &c.], is referred to.

Title: Indirectly heated cathode structure and method of assembly
IPC: H01J1/24
Filed: 1953-09-16
Abstract: 725,111. Thermionic-cathode tubes. RADIO CORPORATION OF AMERICA. Sept. 16, 1953 [Oct. 11, 1952], No. 25651/53. Class 39 (1). In an indirectly heated cathode, the heater 13 is separated from the cathode sleeve 10 by a spacer comprising a conductive member with insulation thereon, so that substantial portions of the space between heater and sleeve are left open. In the embodiment shown, the spacer is formed bv a helical wire 22 with an insulating coating 23. This grips the . enclosed heater tightly enough to deform it slightly, which accordingly impedes the tendency of the heater to " creep." The pitch of the helix is sufficiently wide to allow of good heat transfer from heater to cathode. The end 24 of the conductive core of the spacer helix may be connected to ground, together with the cathode sleeve, the helix thus forming a shield for the cathode against electrostatic fields between heater and cathode. In assembling, the spacer helix may be first compressed, and pushed within the cathode sleeve, the heater being subsequently forced into position; or else the heater may be inserted into the spacer first, and the unit so formed pushed into the cathode. The elements may be secured in place by spots of cement 27, 28.
