IPC: F16K1/20
Filed: 1962-07-04
Abstract: 966,146. Valves; Junction pieces. ENCO Ltd. April 19, 1963 [July 4, 1962], No. 25595/62. Headings F2G and F2V. In a discharge valve for tanks wherein a valve urged to a closed position is opened manually, the normal axis of the outlet port is inclined to the normal axis of the inlet port and the normal axis of the mounting face of an outlet adapter is inclined to the normal axis of the adapter outlet so that the angle between the body inlet and adapter outlet normal axes can be varied by the rotational mounting position of the adapter. Pivoted valve member 20 is urged, by a torsion-operated helical spring, upon " O " sealing ring 16 which also acts to seal between the valve body A and an outlet adapter D. The adapter D is bolted to the valve body H at mounting face 12 with the axis C of the mounting face (Fig. 1) at an angle of 11“ degrees to the axis B of the valve body inlet port 11, and the axis E of the adapter outlet port also at 11“ degrees to the axis C of the mounting face 12. The adapter is mounted to the valve body by four equi-spaced bolts and the Fig. 1 disposition of the axis E of the adapter outlet port parallel to the axis B of the body inlet port 11 may be translated to a relative inclination of 22¢ degrees upon 180 degrees rotational remounting of the adapter D.

Title: Process for the manufacture of carbonyl sulfide
Filed: 1960-07-22
Abstract: Carbonyl sulphide, COS, is prepared by reacting CO and S vapour in molar ratio 0,5-2:1 at 500-900 DEG  F. in the presence of a dehydrated crystalline alumino-silicate catalyst having rigid three-dimensional networks made up of unit cells characterized by absence of change in unit cell dimensions upon dehydration and rehydration, and a sorption capacity at 760 mm. and 25 DEG  C. of at least 4% of n-butane.  Pressure may be atmospheric-50 psig. and space velocities 5-25,000 v/v/hr.  Catalysts may be zeolitic molecular sieves, e.g. Na12(AlO2)12(SiO2)12, 27 H2O, Na86[(AlO2)86(SiO2)106 267H2O, or the corresponding Ca salts.  CO enters externally heated jacket 11 at 12 and flows through molten S and aperture 13 to cylindrical reactor 10.  Further CO may be added at 15 and the mixture flows through catalyst on sintered disc 14.  The <PICT:0885871/III/1> resulting mixture flows through S condenser 18 maintained at 120 DEG  C. by steam in jacket 19, and condensed S is separated in 22.

Abstract: 353,300. Heating water by electricity. SMITH, E. W., 31, Legard Road, Highbury, London. Aug. 30, 1930, No. 25956. [Class 39 (iii).] An electrically heated hot-water geyser 1, Fig. 1, has associated with it a switch chamber 2 through which the water flows, initiation of the flow of water by turning on a tap closing a switch in the chamber 2 and thereby energizing an electromagnetic switch 5 controlling the circuit of the heater. The device is shown applied to a threewire system a, b, c, the circuit of the heater taking the full voltage a, c and the circuit of the switch in the chamber 2 taking the low voltage a, b. The switch chamber 2, Fig. 5, has inlet and outlet pipes 3, 4 and the flow of water through holes (not shown) in a plate 50 raises a piston 20 connected by a link 34 to a box 24 pivoted at 32 thereby raising the box and a mercury tube switch contained within it to a horizontal position and closing the circuit. The leads 39 pass into the box 24 and out of the chamber 2 in a watertight manner and the box 24 is packed with paraffin wax surrounding the mercury tube. When the tube is closed, gravity returns the box 24 to its original position.

Title: Apparatus for feeding blanks of cardboard or analogous sheet material to machinery for operating on the blanks so fed
Inventor: KIRBY KEITH ROLAND TALLETT
IPC: B65H3/12
Filed: 1965-06-18
Abstract: 1,108,193. Feeding sheets. KIRBY'S (ENGINEERS) Ltd. 13 June, 1966 [18 June, 1965], No. 25971/65. Heading B6B. Apparatus for feeding sheets from the bottom of a pile 16 to a machine 103, 104 comprises a pile-supporting table 11 with grooves in which one or more open-topped channel-shaped feed members 12 are mounted for reciprocation in the direction of feed, the bottom of each feed member 12 being cut away at 121 so as to act as a slide valve between the member 12 and a suction chamber 24, and the top of the member 12 having cross pieces 13 to provide openings through which suction is applied to the bottom blank. The members 12 are reciprocated by a linkage 18, 19 oscillated by eccentrics 191 on a shaft 201. The top of each cross-piece 13 projects above the surface of the table 11 so that parts of the blank tend to be bent into the spaces between adjacent pieces 13 thus ensuring a more positive feed. When the rear end of a slide moves beyond the rear edge of the suction chamber during a feeding stroke, the chamber and member 12 become open to atmosphere so that suction ceases and the feed of the sheet is continued by rollers 101, 102. The cross-piece 13 at the leading end of each member 12 has slots therein so as to allow suction to be applied to the leading edge of each sheet. According to the width of the sheets, one or more of the feed members 12 may be rendered inoperative by the insertion of filler blocks between the pieces 13. Gates 17 are adjustable to allow one sheet to pass at a time, and adjacent to the gates suction is applied to the bottom blank through an opening in the table 11 connected to a suction duct 25. This causes the bottom sheet to be drawn over rollers 251 mounted in the duct to assist in guiding the sheet beneath the gates 17. The table 11 is provided with a back stop 15 for the pile, and with angle members 161 engaging the front corners of the pile.

In a hair-clipping device comprising a fixed toothed cutting member and a movable toothed cutting member which is arranged to be driven in an oscillatory manner and which is held against the fixed cutting member by a spring, the pressure of which is applied to the movable cutting member at a point on the outer side thereof, the spring is supported on the fixed cutting member, or at the side of the cutting members remote from the movable cutting member, at a point which is situated on the opposite side of the driving point of the movable cutting member from the teeth of the cutting members and, between this point of support and the point of application of the spring, the spring passes through the plane separating the cutting members. As shown in Figs. 1 and 2, oscillatable blade 2 is held against fixed blade 1 by two springs 7 each of which has one end 17 secured to the blade 1, the spring extending through a recess 15 in the edge of the blade 1 around a projection 18 which protrudes into the recess and back through the recess and through a recess 13 in the blade 2, the end 16 of the spring engaging the outer surface of the blade 2. A hole 3 in the blade 2 is engaged by a reciprocable driving member of a dryshaver. In a modification, the limbs 22, 23 of a U-shaped spring 20 pass through recesses 21 in the side edges of a fixed blade 28 and the transverse portion 25 of the spring bears on the outer surface of oscillatable blade 24. The ends 27 of the limbs 22, 23 are accommodated in a groove 26 in the wall 19 of a housing remote from the housing of a dry-shaver. In a further modification, a bent wire has a middle portion 39 rotatably supported in lugs 40 on housing wall 33, an end portion 43 which carries a roller 44 pressing oscillatable blade 32 against fixed blade 31 and an end portion 41 engaging resiliently beneath a catch 42 on wall 33.
