Title: Improvements in or relating to liquid pressure actuated control devices for automatically switching on and off the heating means of liquid flow heaters
IPC: F24H9/20
Filed: 1958-05-16
Abstract: 860,622. Valves. JUNKERS & CO. G.m.b.H. May 16, 1958 [May 17, 1957], No. 15741/58. Class 135. A known liquid pressure actuated control device, Fig. 1, for automatically switching on and off the heating means of a water flow heater, e.g. by controlling the gas valve 31, and wherein the actuating member or diaphragm 12 of the control device, which is arranged in the casing thereof between a high pressure chamber 10<SP>1</SP> and a low pressure chamber 11<SP>1</SP>, is coupled to the regulating member 15 of a water regulating valve and is actuated by the suction effect of a Venturi tube 20 arranged in the water flow passage, the throat 20<SP>1</SP> of said tube communicating through a suction passage 21 with the low pressure chamber 11<SP>1</SP>, whilst a by-pass passage 27 branching off in the flow direction of the water downstream of the water regulating valve 15 but upstream of the Venturi tube and communicating again with the main water flow passage downstream of the Venturi tube, can be progressively restricted by a throttle valve 28 for regulating the temperature of the water to be extracted from an outlet tap 25, is improved in that the by-passage before communicating again with the main water flow passage, communicates with a chamber 44, Fig. 2, in which the water is subjected to a damming effect and which is connected both to the main water flow passage and to the suction passage of the Venturi tube. As shown, the chamber 44 communicates with the downstream end of the Venturi tube 20 through apertures 45 therein so as to provide the damming effect, and the damming pressure in this chamber is communicated, past a narrow annular gap 40 formed by a grooved collar 39 of the tube, to an annular chamber 36 surrounding suction apertures 35 of the Venturi, the area of the annular gap 40 being about half the total area of these suction apertures. Thus when a larger quantity of water of lower temperature is required to be extracted from the tap 25, the throttle valve 28 is gradually opened by hand and the increasing damming pressure acts to reduce the suction in passage 21 so that the diaphragm moves to further open the water regulating valve 15, whereby an additional quantity of water corresponding to the increasing opening of the by-pass valve 28 is allowed through by the water regulating valve 15.

Filed: 1944-08-18
Abstract: 583,085. Strip-severing apparatus. WILLIAMS, W. P. (Standard Register Co.). Aug. 18, 1944, No. 15855. [Class 31 (i)] A strip-severing apparatus for cutting up printed forms such as a series of cheques, bills, invoices &c. is constructed with means for severing the strip along transversely weakened lines by means of a pulling action produced when a strip which is continuously advanced by pin - wheels 15 mounted on a shaft 13 is gripped between a pair of snubbing rollers 7, 8, and a pair of tensioning rollers 9, 10 driven at a higher speed, the rollers 7, 8 and 9, 10 being arranged to grip the strip intermittently. The rollers 7, 9 are mounted in fixed bearings and are driven by a motor 6 and pulley 21 tensioned by the weight of the freely mounted motor. The shaft 11 of the roller 7 is driven by reduction gearing 23, 24, 25, 26 from the shaft 12, and the rollers 8, 10 are mounted in frames 17 pivoted about a fixed shaft 16 on which are mounted arms 39 carrying a cutting or perforating disc 38 for cutting or weakening the strip inside the feed perforations so as to enable these to be cut off at once or subsequently. The frames 17 are oscillated by cams 18 on a shaft 19 so as to cause gripping of the strip by both sets of rollers 7, 8: 9, 10 simultaneously and consequent tearing of a sheet which is guided by the curved upper part 47 of a receptacle 35 into the receptacle. When the rollers separate, the feed is continued by the feed wheel 15 which is constantly driven in spite of the reciprocating movements of the frames 17 in which it is mounted. The cam shaft 19 is driven from the shaft 11 by means of change-gears comprising a wheel 29 mounted in an adjustable frame 30 pivoted about the shaft 11 and arranged to engage a gear 33 of variable size on the shaft 19, the gear ratio being adjustable to correspond to tickets &c. of variable length. To permit of variation of the pressure between the rollers 7, 8 and 9, 10 the shaft 16 is carried by eccentric mountings 43 which can be held in variable position by screws 44, and the rollers 20 on the frames 17 which are engaged by the cams 18 are similarly mounted in adjustable eccentric bearings 45. The arms 39 may be moved by a crank arm 40 to remove the trimming discs from strip severing relation when a new strip is introduced. Specification 560,468 is referred to.
