IPC: B65B25/14
Filed: 1967-11-15
Abstract: 1,253,204. Packaging sheets. ILFORD Ltd. 16 Nov., 1968 [15 Nov., 1967], No. 52033/68. Heading B8C. [Also in Division G2] Relative movement during transporation of a stack of sheet material 1, e.g. photographic film, is minimized by packing between upper and lower sheets of stiffening material 2, e.g. cardboard, wood or plastics, of a size slightly smaller than the sheets 1, and applying a tensioned strapping material band 7, e.g. polypropylene, nylon, rayon/fibre glass, or metal, around corner pieces 3-6, e.g. of polypropylene, high impact polystyrene, copper, steel, aluminium, or wood, which embrace the stiffening material 2. With light sensitive materials, the stack is initially placed in a light-tight folder, e.g. a polyethylene bag, with the stiffening material 2 either within or on the outside thereof. When made of plastics material, the band 7 is joined by metal clips or heat welding. The band 7 is preferably located in channels 10 in the corner pieces 3-6. An insert of stiff material may be located behind the strapping material joint 8 between the adjacent corners, and may comprise tabs extending from the upper and lower cardboard stiffening sheets which are folded over Fig. 2 (not shown), to enclose the stack between the corner pieces. When such a pack of film is fitted into an end opening box, the band is cut and removed followed by the adjacent corner pieces and the stiffening material.

Abstract: 1,257,965. Drying metal sponge. NATIONAL DISTILLERS & CHEMICAL CORP. 28 Jan., 1969 [12 Feb., 1968], No. 4700/69. Heading F4G. In a continuous process of drying reactive metal sponge (e.g. titanium, zirconium, hafnium) the metal sponge is continuously conveyed by a rotatable spiral conveyer through a heated evacuated chamber 15. The metal sponge is fed to the chamber 15 by vibration screw feeder 11 through rotating valves 12, 13 and 14, the space between valves 13 and 14 being evacuated. The metal sponge is conveyed through the chamber 15 by a screw conveyer and discharged through rotating valve 40 into container 41 to which argon is supplied during filling. The chamber 15 is heated by hot fluid (e.g. steam, chlorinated biphenyl) circulating in coils around the chamber. The chamber 15 may be evacuated by a liquid jet type pump. Argon may be fed to the chamber 15 in the event of a leak.

Abstract: 1,259,394. Hydrostatic transmissions. INSTITUT FUR HYDRAULIK. 4 Feb., 1969, No. 5939/69. Heading F2D. [Also in Division Fl] A conjoint control for a diesel engine 1 and an hydrostatic transmission 5, 6 comprises a first double cam device 4 acting via a linkage 21 on a fuel injection pump 2 and via a linkage 22 on an hydrostatically amplified engine-driven centrifugal regulator 3 which acts on the pump 2 and, through a control valve 10, on a second double cam disc 7 controlling the displacement servos 8, 9 of the pump and motor 5, 6 respectively. A cut-off valve 12 disconnects the piston/cylinder 11, controlling the double cam disc 7, from the control valve 10 to allow direct mechanical actuation of the cam disc. On turning a first cam disc in the device 4, linkage 22 increases the tension of the spring in regulator 3, causing a pivot point 25 in the linkage between the regulator 3 and pump 2, to move to increase flow from the pump 2 and, via control valve 10, to adjust the transmission 5, 6 to reduce the load on the engine. The engine speed thus increases until pivot 25 is returned to its original position, and the flow from the fuel pump 2 returns to its original value. On turning a second cam disc in device 4, the linkage 21 moves the pivot point 26 to increase the flow from fuel pump 2 without moving pivot 25, increasing the speed of the engine 1. With increasing engine speed, the pivot 25 moves to adjust the transmission to increase the load on the engine 1, and to temporarily reduce the fuel flow from pump 2 The engine speed then returns to its original value returning pivot 25 to its original position. The engine then runs at constant speed with increased fuel injection and under increased load. Overload relief is provided by a relief valve 15 which, on the pressure exceeding a predetermined value in the delivery and return lines between the pump and motor 5, 6, opens to direct the pressure fluid through a valve 13 to one side of the piston/cylinder 11 to adjust the transmission to reduce the load on the engine. Engine braking is provided by positioning cam device 4 in its idling position and moving the valve 13 to its second position B connecting the other side of the piston/cylinder 11 to the pressure source.

[Also in Division F1] In an hydraulic accumulator having a gasfilled bladder 2 provided with a valve member 8 which, when the accumulator is discharged, cooperates with a valve seat 6, the movement of the valve member 8 is damped by a dashpot 9, 10. The dashpot 9, 10 cushions the impact between the valve member and its seat and also prevents liquid from being trapped in the accumulator by premature closure of the valve. In the embodiment shown the dashpot consists of a cylinder 9 fixed to the valve member 8 and a loose fitting piston 10 fixed by a rod 7 to the accumulator container. To increase the damping just before the valve closes, the rod 7 may be provided with a large diameter and arranged to enter a bore 12 in the valve 8. The piston may be carried by the valve 8 and be movable within a fixed cylinder, Figs. 2 and 4 (not shown).
