Title: Improvements in and relating to control circuits for gas triodes
IPC: H03K17/52
Filed: 1938-08-26
Abstract: 521,941. Valve relaying circuits. THORNTON, A. A. (Philco Radio & Television Corporation). Aug. 26, 1938, No. 25119. [Class 40 (v)] In a circuit for con trolling gas triodes by a high frequency signa applied to the grid and with an alternating supply to the plate and grid of predeterminec phase and magnitude the arrangement is such that the space path is rendered conducting by the signal. The Figure shows a radio frequency input 8 and a resistance-condenser combination 6, 7, for adjusting the phase applied to the grid from the transformer 2. A condenser 5 may be associated with the load 3 to ensure a more or less continuous flow of current, while a resistance 4 may be used to limit the peak current and modify the time constant of the circuit 3, 4, 5. The phase shifting network 6, 7 is preferably adjusted so as to ensure that firing occurs early in the alternating current cycle while by making the time constant of the elements 9, 10 greater than that of the supply the grid bias, due to rectification of the alternating current applied to the grid, is reduced after the break-down of the tube by ionisation so that if the tube operates with the first signal impulse it will tend to operate on the following impulses, but failure to operate will increase the grid bias and thus tend to prevent operation by succeeding impulses.

Title: Improvements in or relating to the concentration of fluorspar values from fluorspar ores
IPC: B03B7/00
Filed: 1929-08-19
Abstract: 319,685. Aluminium, Ltd., (Assignees of Williams, J. C., and Greeman, O. W.). Sept. 26, 1928, [Convention date]. Flotation processes.-Fluorspar is separated from gangue containing a substantial amount of calcite by a froth-flotation process following treatment of the ore to remove a large proportion of the slimes. The slimes are removed from the crushed ore either by frothing or preferably by repeated agitation with water, the water and slimes being syphoned off after settlement of the ore, and the deslimed pulp is treated with a frothing agent comprising a mixture of oleic and cresylic acids, preferably in approximately equal quantities. Sodium oleate and phosphocresylic acid may replace oleic and cresylic acids respectively. The froth and the material carried over with it are collected, diluted with water, and again frothed with or without the addition of more frothing reagent. This cleaning of the froth is repeated two or more times, the froth from the final operation being taken as the final concentrate. The use of sulphates, e.g. aluminium' or copper sulphate, and sodium sulphide as depressants, and of oleic acid, or sodium oleate with soda ash, and oleic acid with pine oil as flotation agents is referred to.
Patent GB-863032-A (GB)
Title: Improvements in or relating to knitting method and machine
IPC: D04B9/24
Filed: 1957-08-12
Abstract: 863,032. Knitting. SCOTT & WILLIAMS Inc. Aug. 12, 1957 [Aug. 27, 1956], No. 25456/57. Class 74 (2). The sinkers of a cylinder and dial machine are given inward and downward movements at a point following the location of the drawing of the stitches whereby the nebs of the sinkers engage the sinker loops and urge them inwardly and downwardly away from the needles. Thus untensioned rib fabric, particularly an initial portion, is urged away from the needles in such manner that the tension imposed on the sinker loops urges the needle loops of the previous courses away from the needles, particularly the dial needles, and prevents a loading-up of loops on the needles. In producing a 1 X 1 or 2 x 2 rib fabric on the machine starting on bare needles, a rack, tuck or normal held loop welt may be produced with or without the sinkers operating with their inward and downward movements. In the case of a rack welt involving shogging of the dial, the dial is shogged during the second course when the dial needles do not take yarn. As a result the dial needle loops extend across the cylinder needle loops as is shown for a 1 x 1 rib fabric in Fig. 10 and for a 2 x 2 rib fabric in Fig. 12. Prior to the start of a 2 x 2 rib welt the dial is moved so that one needle of each pair of dial needles extends between the pair of cylinder needles. After completion of the welt and on commencement of normal rib knitting a cam 140, Fig. 5, positioned somewhat after the normal stitch drawing cams, is introduced to engage the butts 16 of the sinkers and to draw them outwardly against the action of the usual spring band 20. This action causes the upper edge of a recess 22 in the back of each sinker to move over a cam 144 whereby the sinker is tilted upwardly, as shown in Fig. 7. Upon release of the butt 16 from the cam 140, the sinker is urged inwardly by the band 20 and slides in its raised position off the cam 144. The lower edge of the usual guiding slot 28 provided in the sinker is of two levels having a forward lower level 36 and a rearward upper level 32 connected by a sloping portion 34. The level 36 is just clear of the cylinder flange when the sinker is engaged by cam 144 and as the sinker rides inwardly and downwardly off the cam 144 the portion 34 is engaged by the cylinder flange. Simultaneously the sinker neb 26, which is provided with angular ledges 27, 29, moves downwardly to clear the dial and to engage over the sinker loops. Further inward movement of the sinkers causes the level 32 to ride under the cylinder flange thereby further urging the sinker downwardly as it is moved inwardly by the band 20 to the position shown in Fig. 9. During transfer operations a cam 160 is rendered operative and engages the backs 23 of the sinkers under influence of a spring 156 and serves to assist the band 20 during these operations when the tension of the loops is increased. Specifications 701,972 and 863,033 are referred to.

Title: Cushioned biscuit cutter
IPC: A21C11/10
Filed: 1962-07-05
Abstract: 961,248. Biscuit cutting presses. WERNER MACHINERY CO. July 5, 1962 [July 5, 1961], No. 25829/62. Heading B5A. In a press used in e.g. cutting and dimpling biscuits, the length of the stroke of the ram 23 is controlled by a pressure responsive cushioning means 20, carried by ram suspension means 18. As shown in Fig. 1 the ram carries biscuit cutters and dimplers 32, and is reciprocated by collars 28 which are eccentrically mounted upon a shaft 14. The dough is supported upon an endless belt which runs over a plate 38, carried by a membrane 41 under which is a cushion of pressurized air in a cavity 40. The cavity 40 is connected by a conduit 102 to a space 100 above a valve 82 (Fig. 2) of the cushioning device in such a way that the pressure in space 100 remains constant. If the length of the stroke of the ram is too great the ram will abut the belt and cause a compressive force in member 44 of the ram suspension means, thus forcing the piston 60, contained in cavity 54, to move upwards. Fluid from the upper chamber 56 is forced through one way valve 82 and conduit 80 into the lower chamber 58 thus retaining the piston 60 in its raised position and effectively shortening the stroke of the ram. If the ram does not contact the belt i.e. the length of the stroke is too short, the member 44 experiences a tension which forces the piston 60 downwards thus transferring liquid from the lower to the upper chamber, through a restricted orifice 88, which effectively lengthens the stroke of the ram. By adjusting the pressure in space 100, the valve 82, and thus the cushioning means, may be made responsive only to forces above that experienced when cutting dough alone, adjustment therefore occurring only when the length of the stroke is too long or too short and abnormal forces are encountered. A one-way valve may be used instead of orifice 88 and in a further embodiment a twoway valve may replace both orifice 88 and valve 82. In another embodiment (Fig. 7) the fluid flows from the lower to the upper chamber through an orifice 294 in a plug 216 of a valve 290. Any excess pressure in the lower chamber is transmitted to a reservoir 208 which causes a valve 261 to open and admit fluid to the upper chamber through a conduit 283.
