Title: Improvements in and relating to apparatus for piling strips of material
IPC: B65G47/82
Filed: 1953-11-06
Abstract: 740,297. Roller conveyers; load-handling machines. AKTIEBOLAGET SVENSKA METALLVERKEN. Nov. 6, 1953 [Nov. 7, 1952], No. 30856/53. Classes 78 (1) and 78 (3). In apparatus for piling strips of material, the strips are conveyed to the site 5 by a roller conveyer 2 and are discharged therefrom by pushers 7 mounted on bars 8 which move transversely to the conveyer, the bars being moved simultaneously to discharge a strip and retracted oneby one, or in sets, to deposit it. When a pile is completed, it is moved away from the conveyer by a series of carriages 25 to permit the formation of another pile. Each rail 8, Fig. 2, moves between a pair of guides 9 and is connected at 17 to a chain 16 which is driven by a motor 18. The site 5 is formed with channels 24 in each of which is disposed a pair of beams 26, Fig. 5, on the lower flanges of which run the wheels of a carriage 25. Each carriage is connected to a driving chain 29. The beams 26 are supported by the plungers 38 of fluid-pressure cylinders 39, so that they can be raised to bring the carriages into contact with the bottom of a pile to raise it above the site and, after the carriages have been moved to transfer the pile, lowered to deposit the pile in the new position. The strips are removed one by one from the piles by a device consisting of rollers 42, 43 and a strip separator 44. Specification 737,069, [Group XVI], is referred to.

Abstract: 1,141,217. Drilling machine. DONETSKY NAUCHNO-ISSLEDOVATELSKY UGOLNY INSTITUT. 5 July, 1967, No. 30947/67. Heading B3C. [Also in Division H2] A mining drill comprises a tool 6, Fig. 1, connected to a screw 2 at 7, the screw being driven by the rotor 5 of an electric motor, through gears 3 and clutch 4, and a nut 8 driven at a slower speed by a rotor 9, rotatably mounted on the shaft of rotor 5, through gearing 10. In operation, with rotors 5, 9, in series, the nut and screw are rotated at different speeds, tool 6 rotates and is fed up to the work. When the tool abuts the work, an axial force is transmitted to the nut by the screw, and the nut is accelerated, owing to friction between the members. Rotor 9 is now driven by the nut, and the power generated is passed through the magnetic flux of the stator, to thus increase the efficiency of rotor 5. In a modification, rotor 9, Fig. 3, drives screw 2 through gearing 15, and rotor 5 drives tool 6, and also nut 8, through gearing 16 and dog clutch 17.

Title: Acceleration sensitive device
IPC: H01H35/06
Filed: 1963-08-07
Abstract: 1,027,765. Inertia switches. BENDIX CORPORATION. Aug. 7, 1963 [Aug. 27, 1962], No. 31208/63. Heading H2B. In order to avoid false indications an acceleration sensitive switch employs a dashpot, time delay device to prevent actuation of the switch until after the passage of a predetermined time, thereby ensuring that there is no response unless the acceleration is maintained for that time. A seismic mass 19 is movable, against a spring 25, under the influence of acceleration. It is connected by a spring 28 to a piston member 26, which carries a bridging contact ring 36. The casing 22 is filled with oil and although this does not have any appreciable damping effect on the mass 19, owing to the clearance provided, it effectively retards the member 26, which follows, with a predetermined time delay, owing to the tension in the spring 28. The contact ring 36 consequently moves from contacts 39, 40 to contacts 41, 42. Initial tension in the spring 25 is adjusted by the axial position of the stop member 24 and a screw stop 51 determines the limiting position of the mass 19. A mass of resilient material 35, such as neoprene, compensates for expansion of the damping fluid.

Abstract: 653,727. Securing wall panels. HOROWITZ, A. Dec. 7, 1949, No. 31351. Convention date, Dec. 15, 1948. [Class 20(iv)] The front part of a covering strip for panelled walls s is wedged to a separate backing part after they have been engaged in position on a wall structure to form an H- shaped member which embraces the edges of two adjacent panels, the final locking together of the two parts causing no relative longitudinal movement between them. The flanges 8 of a channelled inner member 5 of the front part are adapted to slide between the inturned flanges 6 of an outer member 4. Hookshaped members 10 connected within, and extending through openings spaced along the bottom edge of, the channel-shaped web 12 of a backing part 13, engage in corresponding openings formed along the bottom side of the channelled part 5. The inner member 5, which is shorter than the outer member 4, may be levered downwards, Fig. 3, by a pin, not shown, which, extending through a hole 8 in the member 4, may engage in one of a series of holes 17 formed in the inner member 4. This locks the inclined surface 11 of each hook 10 against an upper edge 19 of the corresponding opening 9 and draws the members 4 and 13 together to grip panels 1, 2. Notches may be provided along the surfaces 11 to facilitate this. The hooks 10 carry studs 16 which are riveted in openings 15 on each side of each opening 9, and they may be provided with extension members for attachment to the wall structure. In an alternative construction the hooks are provided on the member 5 and corresponding wedging surfaces are formed in the strip 13.

IPC: F24F12/00
Filed: 1976-07-29
Abstract: A high performance ventilation system with means for recovering a high percentage of sensible and latent thermal energy from the exhausted air for return via the supply air. Two matrices of thermally absorbent, expanded honeycomb material are respectively alternately interconnected with fan-driven supply and exhaust paths via a valve device to store energy in one matrix while retrieving energy from the other. Constant air flow direction is maintained in the ventilated area. The valve may be thermostat controlled.

In operation, on compression, liquid is metered between the ribs 9 and their respective associated grooves in the piston. The return of the plunger is effected by the differential pressure acting on opposed faces of the piston and piston rod. This action may be implemented by a spring.
