Abstract: 1,112,673. Packaging partition structures. OWENS-ILLINOIS Inc. 11 May, 1965, No. 19766/65. Heading B8C. Crossed strip partition structures are collapsed for storage by advancing them on a conveyer into contact with endless belts whose vertical surfaces form a narrowing channel into which the structures are drawn as they collapse on a diagonal, The conveyer includes bars 11 which engage the structures P and also operate valve means 18 through a feeler 13 controlling a pusher 36 for pressing the collapsed structures into a horizontal stack. A guide 29 urges the structure against a continuously driven belt 23, when collapsing commences. The structure next contacts the second belt 20, driven at the same speed, and is flattened between both belts as it passes on to a table 34 in front of the pusher. It is retained by yieldable upper and lower gate bars 45, 37, respectively until thrust on to the stack on a table 47. In order to cope with various sizes of structure, the position of the guide 29 and the distance between the belts 20, 23 are adjustable, as are the height of the bar 45, and the position of the table 47 relative to a guide 72. The timing of the pusher operation may be varied by moving the feeler 13 along a rod 14 and the pusher height may be altered by changing rods 137, 138.

Abstract: 806,777. Thermal regenerators. GENERAL MOTORS CORPORATION. June 25, 1957 [July 5, 1956], No. 19941/57. Class 64(1) In a thermal regenerator for heat exchange between gases at different pressures and having a rotary annular drum or disc type matrix 10 of rectangular crosssection, each of two seals provided for sealing that part of the matrix which is momentarily receiving heat from that part which is releasing heat, comprises a rectangular metal frame constituting a primary seal 31 through which the matrix passes and consisting of a seal bar 34 extending across the "cold" face of the matrix rigidly connected at each end to a plate member 36 extending across the edge of the matrix, and a seal bar 37 extending across the "hot" face of the. matrix and connected to the edge members 36, the surface of the bar 37 which lies adjacent the "hot" face of the matrix being curved to approximate to the curvature which that face assumes under working conditions. In the form shown, each of the two primary seals is carried in an outer fixed and rigid frame 25 consisting of an inner beam 23 and an outer beam 24 connected by side plates 26, relative movement between the primary seal 31 and the rigid frame 25 being accommodated by asecondary seal 32 bridging the gap between the primary seal 31 and its rigid supporting frame 25 and consisting of a thin flexible sheet of metal the edges of which are received in grooves in the primary seal 31 and frame 25. The primary seal is pivotally mounted in the frame 25 on trunnions 66. Rollers 67 are carried from the upper bar 34 of the primary seal and are caused to ride upon tracks 18 on the matrix by springs (not shown) tending to urge the primary seal radially inwardly of the matrix. Fig. 5 shows the matrix distorted under working conditions. The seal bar 37 at the "hot" face of the matrix has expanded and pushed outwardly the inner ends of the members 36. Rigid connection between these members and the seal bar 34 at the "cold" face of the matrix has deformed this bar to a shape conforming with the contour of the "cold" face of the matrix under working conditions. The bar 37 is shaped initially so that when expanded it likewise conforms to the contour of the "hot" face of the matrix. Edge seals 53, 56 of graphite may be provided as shown, the seal 56 being resiliently mounted to accommodate expansion of the matrix. Two co-axial matrices may be utilized the resiliently mounted edge seals 56 for each matrix then being carried in a single block 27 disposed between them (Fig. 5).

[Class 47 (ii)] An extinguisher comprises a casing a adapted to be charged with compressed gas by way of a valve k and passage a<3>, or by means of a gas capsule, and an inner container for liquid in the form of a coil b. The inlet end b<1> of the coil communicates with a chamber a<1> connected by a non-return valve c to a chamber a<2> which communicates with the passage a<3> and is closed by a cap d. The outlet end b<2> of the coil is closed by a diaphragm e above which is a piercer g<1> raised by a spring h. When the diaphragm is ruptured, gas pressure acting through the valve c ejects the liquid through the outlet i, which may be fitted with a perforated spraying plate i<1> or with a nozzle. The piercer is adapted to be forced in by a spring-biassed lever m<1> normally held inoperative by an arm m<2> co-operating with a bimetallic strip n. The latter is carried by a pivoted arm p adapted to be tilted by a lever p<2> for manual operation of the extinguisher or by a rod or the like s for remote control. The strip n may be replaced by a fusible link, and the seal e and piercer g<1> by a spring-pressed valve. The Provisional Specification describes the provision of a discharge valve closed by a spring, and opened by a rocking lever for remote control, or by a stronger spring acting on the valve spindle when released by fusion of a link.

Alternatively, the blades may be driven by fluid-jet reaction. Fig. 3 shows two engines 22, 27, the engine 27 being permanently coupled to a tractor screw 28, and the other being adapted to be clutched to a tractor 24 when the propeller 21 is to act as a screw, or to a tractor 23 when the propeller is to be used as a plane. The blades, which are of symmetrical outline, may be feathered and varied in pitch for balancing, rotational gliding, and for checking the descent at landing. During forward flight, the propeller is adjusted and held in a transverse position by hydro-pneumatic means described in Specification 172,331. The propeller 21 is mounted on a hub rotating in ball-bearings on the car, and the frictional torque is counteracted by arranging a rudder 31 in the wash of the propelling units. Land wheels 12, 13, 14, 15 are arranged on spring undercarriages beneath the car.
