Title: Reversible refrigeration system
IPC: F25B13/00
Filed: 1976-05-25
Abstract: 1529614 Valves CARRIER CORP 25 May 1976 [23 June 1975] 21708/76 Heading F2V [Also in Division F4] A reversible heat pump comprises a compressor 17, a four-way valve 20, heat exchangers 11, 12 and a pair of valves 15, 16 which act as expansion valves or through-flow valves according to the flow direction of the refrigerant. The valve 15, Figs. 2, 3, comprises a housing 30 formed with a flow passage 35 communicating with a cylinder 36 containing a free-floating piston 45. The open end of the cylinder is provided with a nipple 37 having a tapered internal opening 38. The piston is formed with a metering port 46 and, in its outer periphery, with fluted channels 47. In the position shown, the channels 47 are closed by engagement of the piston with the end wall 50 of the cylinder, thereby allowing refrigerant to flow only through the port 46, so that the valve acts as an expansion valve. When the refrigerant flow is reversed, the piston moves to the right and engages the nipple 37 whereby the refrigerant may flow through the channels 47. The total cross-sectional area of the channels is equal to or slightly larger than that of the refrigerant supply line 14 interconnecting the two heat exchangers 11, 12.

Patent GB-1312703-A (GB)
Title: Extrusion press
IPC: B21C23/08
Filed: 1970-05-06
Abstract: 1312703 Extruding; billet piercing MASCHINENFABRIK SACK GmbH 6 May 1970 [29 May 1969] 21902/70 Headings B3H and B3P An extrusion press which can be used to produce either rod or tube includes an hydraulic piercer piston 13 inside the main extrusion ram 4 and a control valve 20 actuated in dependence on the position of the piercer tip 15a relative to the die 8 to supply fluid to the piston to keep it substantially stationary. In one form the valve is actuated by an abutment 30 on a cord 27 attached to the piston at one end and a spring- biased pulley 28 at the other end. Alternatively the valve 20 may be electrically actuated or a variable delivery pump could be used to vary the supply to the piston. In operation the piercer tip 15a oscillates slightly within the die. The press can be used to extrude tubes using a piercer which moves with the ram in which case the abutment 30 is positioned so that the valve 20 is not actuated and hence the piercer is maintained fully extended relative to the ram 4 under the control of a valve 19. When the press is used to extrude rods the piercer is maintained fully retracted by appropriately positioning the valve 19. For extruding tubes using a substantially stationary piercer the valve 19 is closed and the abutment 30 positioned so that its separation from the valve actuator 32 is equal to the distance between the piercer tip 15a and the die 8. Hence as the ram advances the piercer is fully advanced until it enters the die. For extruding tubes using a moving piercer the valve 19 is actuated to fully retract the piercer into the ram. When the ram abuts the workpiece a pressure sensitive switch closes the valve 19 to keep the piercer retracted. The ram upsets the workpiece and is then slightly retracted to allow for the backward extrusion caused by the piercing. After piercing the piereer is maintained in its advanced position during the extrusion.

Abstract: 1,006,345. Folding paper. ADDRESSOGRAPH - MULTIGRAPH CORPORATION, CHARLES BRUNING DIVISION. May 28, 1964 [July 23, 1963], No. 22088/64. Heading B6H. A paper web 16 having transverse crease lines 16b at regular intervals to provide rectangular portions 16a is stacked in a container 48, 50, 52 in zig-zag fashion, with the portions 16a superimposed, by stationary guide means comprising a lower plate &c. 54 and an upper plate or set of fingers 60 which define a throat which has a depth smaller than the length of the portions 16a, and is positioned above the back 50 of the container. In operation, the leading end of the web 16 is fed by belts supported on pulleys 45 and by pressure rollers 46, to impinge on the fingers 60 and be directed downwardly to engage the wall 50, and finally to abut the wall 48, as shown in Fig. 5. Continuing movement of the web causes it to fold at its first crease 16b, and the first portion 16a lies on the wall 52. On further feeding, the restricted throat causes the second portion 16a to be placed in compression and to buckle back about the second crease 16b, as shown in Fig. 6; the creased web is now moved forward so that the second crease 16b engages the wall 48 and the second portion 16a is superimposed on the first portion 16a. These operations are then repeated to cause the entire web to be stacked in zig-zag fashion independently of the speed of the web and without the aid of moving parts. The apparatus is described as applied to a copying machine, the web being of sensitized paper originally stacked in zig-zag fashion in a container, and fed around a cylinder with a web of negative material past a source of light. The two webs are then separated, and the web 16 is fed by rollers and belts towards a discharge position, where it is zig-zag folded and stacked as described.
