Title: Refrigerated display container having a single air conduction
Inventor: ABRAHAM FAYEZ F
IPC: A47F3/04
Filed: 1981-01-17
Abstract: A refrigerated display container having a single air conduction and an automatic defrosting system which operates with ambient air. The access opening can be located either in the top or in the front. The single air conduction extends approximately in a U-shape around the display container and has apertures on the mutually opposite sides of the access opening. Arranged in the air conduction are at least one reversible fan and a set of cooling coils. During a cooling cycle, the fan circulates air through the air conduction in a first direction onto the cooling coils. During the defrosting cycle, the fan circulates the air in the opposite direction through the air conduction and sucks ambient air in. Since the ambient air has a higher temperature than the normal cooled air, it defrosts the system. When the ambient air has passed by the cooling coils and the air conduction, it is blown out of the air conduction to the outside of the display container and leaves the interior of the display container. <IMAGE>

Title: Pallet with shelves
Inventor: AMROGOWICZ ERICH ING GRAD
IPC: B65D19/12
Filed: 1981-07-02
Abstract: The invention relates to a pallet with shelves. The pallet is composed of a base pallet, two upright frames, at least one tier floor and a stabilising frame. In the known case the upright frames are fixed in a base pallet by plug-in pegs. Transverse stresses lead to warped plug-in pegs or to a fracture. The tier floors have edge beads which are placed on angle strips. The edge beads can be damaged. The stabilising frame is merely coupled using fingers into lug-like brackets and secured in position. These parts project outwards and form obstacles as well as sources of danger. The pivoting mountings can be damaged. On shaking the stabilising frames they detach themselves from the plug-in holders. According to the invention, the ends of the upright frames (3) are pushed onto the base pallet (2). The tier floors (4) have beadless floors and reinforcing ribs (21) on the underside. These cooperate with coupling channels (16) on the upright frames (3) and represent binding members which hold the pushed-on upright frames (3) in their operational position. Stabilising frames (5) and coupling elements (38, 39; 30, 31) are situated in the plane of the vertical struts (12). There are no protruding parts and obstacles. There are no longer sources of injury. <IMAGE>

Patent DE-3147508-A1 (DE)
Title: Ram boring apparatus
Inventor: STROBEL CHRISTIAN DIPL ING
IPC: E21B1/30
Filed: 1981-12-01
Abstract: A pneumatic striking and percussion-boring tool operated by liquid air held in cartridge form is described, the liquid-air bottle of which, designed as a piston, has one push-open cone valve each at both end faces. Both valves time the forward and return stroke of the piston independently without the use of slides or passages by impact of the valve stems at the cylinder end. In percussion-boring tools, the boring bit is transposed about the borer axis in a conventional, mechanical manner by a ratchet mechanism or in a novel manner internally by a pneumatic turborotor which is acted upon axially by exhaust air and is free of reaction moment. The piston, designed as a liquid-air tank and performing an independent timing function, can be quickly changed for exchanging the empty piston for a full piston. With the inclusion of a piston recoil spring, starting for striking and rotating is initiated by pressing the tool against the workpiece, and stopping is initiated by removing the tool from the workpiece. Depending on the construction and size, a tank filling lasts for 0.5 to 3 hours of boring or percussion time at up to 1500 bar working pressure.
