Title: Thermally-insulated structural members
IPC: E04B2/56
Filed: 1979-05-01
Abstract: An elongate thermally insulated structural member for use in buildings, especially intended for use as rafters and studs in roof and wall structures, comprises an elongate core e.g. 10 of heat insulating material and at least two covering sheets, e.g., 11, 12 disposed to cover at least a portion of two opposing surfaces of the core. The covering shots are retained on the core by means extending between the covering sheets. The retaining means consist preferably of straps 13 or wire loops tightened externally around the member, but may comprise one or more sheets of plastics material, e.g. The core may comprise mineral wool or rigid foamed plastics, and a central stiffening web (18), Fig. 2 (not shown), or a pair of edge stiffening webs (23), Fig. 3 (not shown) may extend between the covering sheets, which are preferably metal. The edge stiffening members, which box in the core, may be of wood-based material. <IMAGE>
Patent GB-2023523-A (GB)
Title: Vehicle Suspension
IPC: B60G11/22
Filed: 1979-05-29
Abstract: An axle (11) is supported at each end by an axle box (12) and spring means (13) acting between each axle box (12) and an associated rigid vehicle mounting. The spring means (13) has an effective spring centre which acts at a point (20) between the axle centre (10) and the associated axle box (12) so as to reduce the radius of operation (Ry) of the suspension in a yaw condition as compared with conventional suspensions in which the effective spring centre acts at the axle box. The yaw stiffness of the suspension is thereby reduced enabling the axle to self-align radially as the vehicle traverses tight curves and avoid wheel slip. The spring means (13) comprises a pair of spring units (15) arranged one on each side of the axle (11) and each spring unit comprises layers (16a) of elastomeric material sandwiched between reinforcement elements (16b). <IMAGE>

Title: Weapon with retractible barrel
IPC: F41F3/00
Filed: 1979-08-08
Abstract: A weapon for firing explosive missiles comprises a frame 4 and a recoiling mass formed by a barrel-tube 1, a breech block 5 and a cradle 3. The barrel is connected to the cradle for the purpose of opening it with a pivoting movement. A hydro- mechanical recoil brake 10, 6, 66, 9, 70, absorbs the recoil when the shot is discharged and returns the recoiling mass to the forward position. A percussion mechanism 44, 45 is housed in the breech block and controlled by a push rod 48 which is actuated by a pull off mechanism 49, 58 housed in a handle 61. The recoiling mass can be returned in the recoil position by a latch to reduce the length of the weapon for carrying purposes. <IMAGE>

Title: Card index
IPC: B42F17/34
Filed: 1979-11-01
Abstract: A card index comprises a housing 1 containing a drawer 5 which holds a stack of punched cards 7, having punched holes 26 engageable by a row of dogs 11 in the bottom of the drawer and punched selection holes in which selection stop cams 21 can engage. Each card has selection holes in register with all of the stop cams except one. To select a card, a corresponding a button 20 is pressed to rock a key lever 17, 18 and move its associated stop cam 21 downwards. The cam passes through the selection holes in all the cards until it reaches the selected card which has no hole in register with that cam. Accordingly, the selected card and any subjacent cards are pressed onto the dogs 11. The drawer 5 is released by depression of the button 20 and is opened by a spring 38. As it opens, the drawer moves the cards held by the dogs 11 out of the housing with the selected card on top. The cards above the selected card are retained in the housing 1 by the stop cam 21. <IMAGE>
