IPC: F15C1/08
Abstract: 1,053,021. Regulating fluid flow. BOWLES ENGINEERING CORPORATION. Jan. 15, 1964 (Jan. 18, 1963], No. 1851/64. Heading G3H. A pure fluid switch or amplifier has a power nozzle 4, Fig. 1, control nozzles 13, 14, outlets 23, 24 separated by a divider 19, and vents 26, 27 from each outlet to prevent instability due to back pressure or load at the outlets. A slight perturbation, when fluid commences to flow from the power nozzle, will cause the flow to be deflected towards one or other of walls 8, 9 set back from the nozzle whereupon the fluid flow will tend to "lock on" to that wall due to evacuation of fluid from the recess between the nozzle and the wall 8 or 9. The flow will consequently be directed to one of the outlets 23, 24 and a portion will be scooped off by a cusp 29 or 30 of the divider to generate a circulation assisting in maintaining the flow to the one outlet. Some of the circulating flow and some of the flow to the outlet can spill as shown by the arrows. The control nozzles 13, 14 may connect with passages 16, 17 that are the outlets from a similar device constituting a first stage, the control nozzles of which perform presetting and resetting functions. A number of similar devices may be stacked in such a  manner that the outlet 24 of one feeds a vortex chamber constituting a supply chamber to the power nozzle of the first stage of the next device, such an arrangement constituting a multi-stage binary counter. The power nozzles 4 and the resetting nozzles have common supplies, and the outlets 23 are closed at their ends remote from the nozzles 4. In a modification, the walls 11, 12 are eliminated by the positioning of the vents 58, 59 and 50, 55 of the two stages as shown in Fig. 4. In further modifications the first stage has feedback passages 73, 74, Fig. 5, which may take the place of the control nozzles, or is asymmetrical, with a single control nozzle 81, Fig. 6. In the latter example the flow from the power nozzle 78 goes to the outlet 87 when a control nozzle flow is present but otherwise discharges to the outlet 83.

Abstract: 1,229,366. Radio receiving circuits; transistor amplifying and frequency-changing circuits. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 10 Dec., 1969 [13 Dec., 1968], No. 60344/69. Headings H3Q and H3T. In a V.H.F/U.H.F. tuner employing transistors, V.H.F. signals are applied to the base of a transistor 1 operating as a mixer, its emitter being earthed over capacitor 10 and a switch, comprising diode 11 in its conductive state. For U.H.F. signals the transistor 1 operates as an I.F. amplifier, diode 11 being rendered non- conductive and U.H.F. intermediate-frequency signals being applied to its emitter over capacitor 14 and resistor 15 from a separate U.H.F. mixer stage. The V.H.F. signals are applied to the base of transistor 1 via R.F. amplifier 2 and tuned coupling circuit 3: series inductor 4 and capacitor 5, together with circuit 3 presenting a low-impedance to the base of transistor 1 for intermediate frequency. The biasing voltage for diode 11 may be obtained from the supply to the V.H.F. local oscillator 18, both being switched together.

Abstract: 1,231,383. Straightening. REDMAN HEEWAN INTERNATIONAL Ltd., and W. E. ALDRED. 4 June, 1968 [9 June, 1967], No. 26784/67. Heading B3M. In a straightening machine for bars or tubes comprising at least three pairs of driven straightening rolls 10-15, of which one of each pair is vertically movable relative to the other and the centre rolls 12, 13 are vertically movable in unison relative to the outer pairs and which are arranged to rotate the bar or tube as it passes longitudinally therealong, an hydraulic jack 32 is associated with one of the rolls of each pair whereby any excess loading causes a pressure relief valve to open and prevents an increase of a predetermined hydraulic pressure on the bar or tube being straightened. A tube to be straightened is fed forward by a conveyer 22, through driven pinch rolls 17, 18 which feed it to the straightening rolls 10-15 and is finally discharged on a conveyer 23, actuation of the feed devices being controlled by the tube interrupting sonic beams. Each of the upper rolls is connected to a cylinder 32, abutting a cover 33 of which is the lower end 35 of a sleeve 34 which is vertically moved to move the upper roll into the straightening position by a rotating nut 39. Oil is fed into the cylinder 32 below a piston 38 at a pre-set pressure so that when excess pressure is applied to the upper roll due to an oversize tube, a relief valve is opened to maintain the pre-set load in the cylinder 32 and the roll is allowed to rise. When smaller tubes are to be straightened, oil may be fed into a cylinder 47 at a pre-set pressure above a piston 46 to cause the piston-rod 37 to be lowered and engage the baseplate 31 of the cylinder 32. If an excess pressure is applied against the roll, a relief valve is opened to allow the piston 46 and hence the upper roll to rise also. The centre lower roll 13 is connected to its associated roll 12 by linkage (70, 71, 74) (Fig. 3, not shown) so that when the lower roll 13 is vertically moved by introducing oil into a cylinder (52) the upper roll 12 is moved by an equivalent amount. The centre rolls 12, 13 may be vertically moved in unison before the straightening operation or after the leading end of the workpiece has entered the last pair of rolls 14, 15.

If one of the radicals R 1  and R 2  in the phenol derivative of Formula I is hydrogen or if both R 1  and R 2  are methyl groups, then during the reaction the phenolic OH group partly reacts with the phosphorus compound to form the following compounds Specified phosphorus compounds of Formula II are triphenyl phosphite, didecyl-phenyl-, diphenyloctyl-, and di-(nonylphenyl)-phenyl phosphites, phosphorous acid diethyl ester chloride, butyl ester dichloride, and phosphorus trichloride. The products may be used as stabilizers for polymers.

Abstract: 1,232,628. Cutting machines. FAMILIE WALDENFELS G.m.b.H. 25 Sept., 1968 [25 Sept., 1967], No. 45611/68. Heading B5A. Sheets of fabric composed of warp and weft threads, in which the warp threads are of thermoplastic material, are severed from a web of such fabric in which weft threads are omitted at the positions of severance, by applying heat to the web at those positions with or without pressure. On leaving a delivery roll the fabric 1 is scanned by a photo-electric control device 4, 4a which stops the fabric when a weft-free zone comes opposite it. Two clamp bars 6 controlled by electromagnets 5 then clamp the web on each side of the zone and hold it against an abutment 6a whereupon a hot air nozzle 11 is moved across the web at the weft free zone on a transversely moved bar 7. The hot air severs the web and welds together the severed ends; the bars are then released and the severed sheet falls away. Instead of a hot air nozzle the cutting and welding device may comprise a heated cutter which forces the web against an abutment.

A combined stirrer and filter for use in a test-tube or similar container comprises a body 6 having ramp surfaces as at 8, 10 separated by a. partition 12 to which is attached a screen 26. There are vertical slots 18 (and 20, Figs. 2-4 not shown) in the body, which rests on a flat surface 16 or on a spike attached thereto. When the device is rotated clockwise as seen from above, the ramp surfaces cause fluid to flow upwards from their upper ends and through the screen, and to circulate downwards again through the screen in the region of the slots 18, (20). The screen may be cut away in the region of the downward flow so that foreign matter is retained only on its underside. The stirrer is rotated by the action of an external rotating field on the permanent magnet 24 which is received by the void 22. The body 6 may be of plastics and the screen a plastics mesh of 30-40 strands/inch.

A coaxial feed cable traverses the skirt, its outer conductor being connected thereto, and its inner conductor being connected to the unipole. In an embodiment intended for suspension from a meteorological balloon, the unipole 1a, Fig. 3, projects downwardly, and is terminated in a capacitive disc 8. There is an insulating spacer 14 between the disc 8 and the closed lower end of a skirt 2, which is coaxial with the unipole 1a The upper end of the skirt 2 is closed by a disc 13, and a coaxial cable 7 traverses the said skirt, and is connected thereto and to the unipole 1a.
