Title: Fluid Actuated Valve Assembly
IPC: F15B13/04
Filed: 1969-02-19
Abstract: 1,190,356. Fluid-pressure servosystems. BENDIX CORP. Feb.19, 1969 [March 7, 1968], No.8941/69. Heading G3P. A valve comprising a hollow body 12 and an axially shiftable element 14, is characterized by a pair of vortex fluid amplifiers 24, 32, means 40, 42 for supplying fluid to the amplifiers at predetermined relative pressures providing equal and opposite axial forces on the ends 22 of the element so that this latter is maintained in a first position and at a predetermined different relative pressure the element 14 is moved to a second position, and means for equalizing the forces on the ends 22 in the second position. A supply of fluid 76 is fed to inlet parts 66, 68 and further to either of the outlet ports 72, 74 unless the spool 14 is in its central first position. The fluid also flows via gaps 89 to the vortex amplifier 24, 32 to pressurize the vortex chambers. Control pressures Pc 1 , Pc 2  are fed tangentially to the vortex amplifiers 24, 32 respectively. Any predetermined relative increase in one control pressure forces the spool 14 to move axially towards the other vortex chamber to a second position, thus opening one of the outlet passages 72, 74 to control the piston 82. A feedback system includes apertures 50, 60 of varying resistance to fluid-flow to an exhaust 90 so that the feedback pressures Pf 1 , Pf 2  can produce a response in the vortex amplifiers 24, 32 to equalize the axial forces in the second position of the spool 14.

Title: Pulse-width demodulator
IPC: H03K9/08
Filed: 1948-03-30
Abstract: 653,852. Pulse modulation circuits. BENDIX AVIATION CORPORATION. March 30, 1948, No. 9016. Convention date, April 3, 1947. [Class 40 (v)] A detector for pulse width modulated pulses comprises means actuated by the leading edge of the pulses to charge an energy storing device to a fixed level, and means to discharge the device during each pulse, whereby the charge remaining on the device is a function of the duration of the pulses. Width-modulated pulses are applied at terminal 50 in Fig. 5 to differentiating circuit 52, 55, so that valve 51 is rendered conducting only at the instants of the leading edges of the input pulses, and condenser 59 then rapidly becomes charged up to a fixed potential. The pulses are also applied through a normal coupling circuit 54, 56, so that valve 53 is rendered conducting for the duration of each pulse. While valve 51 is cut off, and valve 53 is conducting, condenser 59 discharges relatively slowly through valve 53 to an extent dependent on the duration of the pulse and the voltage across condenser 59 is then of the form shown in Fig. 4, in which variations of pulse width have been transformed into voltage variations which are taken from output terminal 58.

Title: Improvements in or relating to the carding of cotton or the like
IPC: D01G15/46
Filed: 1947-04-05
Abstract: 637,870. Preparing fibres for spinning. CHADWICK, F. April 5, 1947, Nos. 9217 and 27209. [Class 120 (i)] A carding engine is characterized by the provision, behind the doffer roller A, of a rotating cage G which is subjected to internal suction over a portion of its periphery defined by a stationary damper H, so that the resultant induced air current causes the fleece C leaving the doffer A to adhere to the operative portion of the cage's periphery, such fleece (before reaching, or after release from, the suction cage) being passed through a guide plate orifice E whereby it is laterally condensed to form a narrow web, lap or sliver. As shown, fleece C is removed from doffer A by a doffing comb B, and the condensed web or sliver C<SP>1</SP> passes between calender rollers F, F to a pair of suction cages G, G each provided with an adjustable damper H. The speeds of rollers F and cages G are arranged to give an initial draft to the sliver which then proceeds to a coiler can. A perforated plate J directs dust, loose fibres, etc., falling between the cages and the calender rollers, to the lower cage. In alternative arrangements the calender rollers may be dispensed with, and the lower cage may be replaced by a plain roller. The condensing guide plate and calender rollers may be situated behind the cage or cages instead of in front thereof, and the doffing comb B may be dispensed with, the fleece being removed from the doffer by the suction of the cages. A set of drawing rollers may be arranged behind the suction cages to increase any draft provided between the suction cages and the rollers feeding the fleece, to or from the condensing plate, before the sliver is collected in the coiler can. This drawing of the sliver enables the first drawing stage in the subsequent treatment of the sliver to be dispensed with.

Title: Improvements in tipping buckets for aerial rope-ways
IPC: B66C3/00
Filed: 1933-03-28
Abstract: 413,080. Tip - - buckets. KENDALL, R., 383, Moss Lane East, Whitworth Park, Manchester. March 28, 1933, No. 9263. [Class 78 (iv).] A tip-bucket is provided with means for retaining it in the upright position on its return swing, after the dumping of the contents, so that at the re-loading point it is only necessary to re-engage the tripping-latch by hand. The engagement of the arm 1 of a bell-crank lever by a fixed ramp at the dumping-point in order to release the forked bracket 4 in the bucket, also operates a cam 5 to depress the arm 8 of a pivoted lever momentarily and so release a notch 8a from a projection 9 on the bucket. As the arm 1 continues to rotate, the cam reaches a position such that the spring 8b can restore the lever 8. Thus when the bucket makes the return swing after dumping, which is assisted by making the bottom portion relatively heavy, the projection 9 is re-engaged by the notch and it travels back to the loading-station in the upright position so that it is only necessary to re-engage the bell-crank with the bracket 4 by hand. The spring 8b may be dispersed with by over-weighting the notched arm of the lever so that it will return by gravity. The trunnions 2 of the bucket are carried by thick metal straps 11, 14a built round the bottom portion of the bucket.

Filed: 1945-04-13
Abstract: 591,295. Valve relay circuits. SIEMENS & GENERAL ELECTRIC RAILWAY SIGNAL CO., Ltd., and RIDDLE, H. J. N. April 13, 1945, No. 9303. [Class 40 (v)] In a. timing-circuit, a condenser, charged from a source through a resistance to a potential dependent upon the charging period, is dis. charged by a source of equal and opposite potential to the charging source, a period being determined by the time taken by the condenser to discharge to a predetermined potential. Condenser 1, Fig. I, is held normally in a discharged condition due to grid current flowing in the valve. Upon contact 8 being closed, the condenser charges over resistor 7 to an extent determined by the period that the contact is closed. When the contact is released the upper plate of condenser 1 carries the grid negative, cutting off the anode current so that the relay 10 releases. The condenser dis. charges over resistor 9, the grid potential rising and, allowing the valve to conduct and relay 10 to re-operate. The resistor 7 may be replaced by an inductor, and the resistor 7 shunted by a condenser, Fig. 2 (not shown). In a modification, Fig. 3, with contact 8 open, the condenser , 1 charges over resistor 14 and the grid-cathode path of the valve, the closure of contact, 8 operating a high-speed relay 13 to complete the circuit to relay 10. The valve is driven beyond cut off, condenser 1 slowly discharging over resistor 9 to allow the avalve to conduct and relay 10 to operate. In a modification; Fig.,4 (not shown), the contact of the relay 13, when released, completes a charging circuit for the condenser.

Title: Improvements in and relating to billet heating furnaces
IPC: F27B9/22
Filed: 1930-04-07
Abstract: 354,717. Charging and discharging metal-heating furnaces. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(Scovill Manufacturing Co. ; Mill Street, Waterbury, Connecticut, U.S.A.) April 7, 1930, No. 9349/31. Divided on 356,779, [Group XXIX]. [Class 51 (ii).] In a billet-heating furnace in which the billets are pushed along guideways, billet-delivering, infeed-pushing and discharge-pushing mechanisms are caused to operate automatically through a cycle, the operation of a subsequent mechanism being initiated by the operation of a prior mechanism. In the four-track furnace shown, the billets are fed by intermittently actuated endless conveyers 3 to a guideway 6 running across the feed end of the furnace and having vertically movable stop members 33 which are actuated in turn to arrest a billet in front of one of the charging openings. The billets are advanced along the guideway by a ram 11 and are pushed into the furnace by rams 39, 40, 41, 46. At the discharge end the billet tracks 29, Fig. 12, terminate in upward inclines 29a leading to a transverse discharge guideway 47 along which the hot billets are pushed by a ram 63, to be received by a combined discharge door and turntable 73. From this they are pushed by a ram 81 and passed to the tube forming machine described in Specification 356,779. At the discharge end of each billet track is a stop 50 which is advanced to hold the leading billet, and is not withdrawn until the pressure of the charging-ram has been removed from the line of billets. Associated with this stop is a detector head 48 carried by a spring-pressed rod 49 which holds it slightly in advance of the stop. The leading billet pushes in the head 48, and this movement is utilized to control withdrawal of the stop at the required time and to allow one billet to roll into the discharge track. All the moving parts of the apparatus are operated by fluid pressure cylinders, the valves of which are operated by direct current solenoids controlled by switches operated by alternating current solenoids controlled by cams on the various moving parts of the apparatus, and an electric circuit is described by which a complete cycle of operations is controlled automatically, and every operation is initiated by some preceding operation in the cycle. The automatic control can be thrown out of action, and all the operations can be controlled when desired by handoperated switches. Switches, actuating.-An actuating device for a switch in which one-way operation is desired comprises a bell-crank lever 405b, Fig. 22, one arm of which bears against the switch arm 406, while the other carries a spring-pressed pivot arm 405d contacting with the reciprocating cam 405e. When the cam moves to the right the switch is actuated, but on the return movement the arm 405d is pushed aside against the pressure of the spring 405h by the inclined end face of the cam. Specification 338,898, [Class 135, Valves &c.], is referred to.
