Title: Centrifugal blasting apparatus
Inventor: URAKAMI FUKASHI
IPC: B24C5/06
Filed: 1992-05-21
Abstract: Disclosed is an improved centrifugal blasting apparatus for for blast cleaning or shot peening treatment of a selected surface of an object to be treated by throwing pulverized abrasive material onto the surface.  Its wheel casing has an elongated slot to permit pulverized abrasive material to pass therethrough and scatter through the air with centrifugal force, which is given by the blades of the rotary blade wheel.  The inlet suction conduit extends from the blasting cabinet to the wheel casing, and the outlet suction conduit extends from the wheel casing to an associated vacuum pump.   The abrasive material storage or collector is provided in the inlet suction conduit, thus making up an abrasive material circulating loop.  The apparatus uses no force of gravity to supply pulverized abrasive material to its rotary blade wheel, and therefore, the positioning of the rotary blade wheel is not limited with regard to availableness of the force of gravity.  It requires neither air-tight ejector nor screw conveyers or bucket elevators, and accordingly its weight and size can be reduced substantially.

Abstract: A cutting device for a wire-removing machine for severing the tying wires of bales, especially of pulp bales, consists essentially of two elongate knives (5, 6) which can be pushed to and fro relative to one another and which are equipped on each of their cutting sides with a tooth row consisting of teeth (16, 17) arranged at regular intervals in succession and having an undercut on their flanks located at the front in the cutting direction. So that the cutting moment is defined exactly and at the same time to ensure that a gripping device retains the tying wires reliably even before they are severed by the cutting device, the front flanks (18, 19) of the teeth (16, 17) each have at their lower ends, in the region of the tooth root, a receiving pocket (21, 22) for at least one tying wire,  the rear ends of the receiving pockets (21, 22) being designed as a cutting edge (24). The front flanks (18, 19) of the teeth (16, 17)  are designed as obtuse   sliding faces  in their portion between the tooth tip (20) and the respective receiving pocket (21 or 22). (Figure 1)

IPC: F04B27/18
Filed: 1992-12-24
Abstract: A slant plate type compressor having a capacity or displacement adjusting mechanism includes a housing for a cylinder block provided with a plurality of cylinders and a crank chamber. A piston is slidably fitted within each of the cylinders and is reciprocated by a drive mechanism which includes a slant plate having a surface with an adjustable incline angle. The incline angle of the slant plate, and thus the capacity of the compressor, is controlled according to the pressure differential between the crank chamber and the suction chamber. The pressure in the suction chamber is controlled by a valve control mechanism which is disposed in a passageway linking the crankchamber and the suction chamber. An internally controlled safety valve device prevents an abnormal pressure differential between the crank and suction chambers. The internally controlled safety valve device is provided within the valve control mechanism, thereby obtaining an easily manufactured slant plate type compressor having a durable and reliable capacity adjusting mechanism with a safety valve device.

Patent CA-2091626-A1 (CA)
Inventor: BORENS MANFRED
IPC: F24C15/04
Filed: 1993-03-15
Abstract: In a window for ovens, in particular household baking ovens, with a window structure that consists of several panes, at least one of the panes is angled in comparison to the other panes. Because of this a lower outer surface temperature results on the outer pane of the multiple pane arrangement turned away from the oven inner chamber with elevated temperature. The frame of the multiple pane arrangement can also have openings on the top and bottom in the area between the outside pane and the center pane. In combination with this measure, which permits convection of the outside air through the outer pane intermediate space, an additional reduction of the temperature of the outer pane can be achieved. This air convection can be increased by the fact that the angled center pane converges toward the outer pane at the top.

Abstract: A protective passive oxide layer is formed on the inner surfaces of metal heat pipes or tubes including their end caps, welds and accompanying hardware through the use of an oxygen encapsulation method.   After cleaning the tube and its accompanying parts, the tube is reassembled and existing gases within the tube are removed thereby creating a vacuum inside the tube.  The tube is then filled with pure oxygen and sealed.  After the oxygen is sealed within the tube, the sealed tube is heated thereby forming a passive oxide layer, such as magnetite (Fe3O4) on the inner surface of the tube.
