Title: Improvements in or relating to tobacco-feeding machines
IPC: A24C5/39
Filed: 1929-09-05
Abstract: 339,606. Grupe, W. F. Sept. 5, 1929. Cigarette-making machines.-In a machine in which a tobacco container has an aperture opening on to the surface of a carded roller or other means which conveys the tobacco more or less uniformly to the other parts of the machine, for example as described in Specification 327,675, the feed of tobacco is rendered more uniform by causing it to take place vertically upwards towards the carded roller, either by conveyer belts or by plungers, paddle blades, or other pusher means. Fig. 2 shows a paddle device comprising a series of blades 20 carried by a chain and arranged to press the tobacco up a conduit 27 to the carded roller 10. The blades are feathered by the engagement of arms 22 with a cam groove 21. Instead of paddles, the tobacco may be fed upwards by a pair of conveyer belts, which constitute the sides of the vertical conduit. In another form, the tobacco is pressed into the lower end of the conduit by a horizontally moving plunger, and is fed up the conduit by a vertical plunger. Fig. 3 shows another device comprising a U-shaped conduit 28, to which the tobacco is fed by a belt 31, and along which it is forced by a plunger 29. The belt 31 may be connected to weighing-means as described in Specification 338,908. The carded roller 10 may be arranged so that its weight, partly counterbalanced at 34, bears on a spring-pressed sliding section 35 of the conduit, the vertical movement of the roller due to irregularity of feed being used to adjust the tobacco-feeding means. Specifications 329,253 and 329,256 also are referred to.

Title: Improvements relating to flow control valves
IPC: G05D7/01
Filed: 1958-08-22
Abstract: 849,386. Fluid-pressure servomotor control systems; valves. ELLIOTT BROS. (LONDON) Ltd. (Fisher Governor Co.). Aug. 22, 1958, No. 27060/58. Class 135. A diaphragm valve comprises a dome-shaped seat 20, Fig. 1, having a set of ports 30 communicating with the inlet 14 and a set of ports 32 communicating with the outlet 18 and an elastic diaphragm 38 secured to the valve casing at its edge 44 and stretched so as to fully engage the dome under conditions of no flow. A loading pressure is applied at 52 and may be controlled by inlet pressure at 54. A single pipe line may be provided with two domes and diaphragms, the passages 18 being curved and merging into a single outlet. Eight applications of the valve have been described. In the pressure regulating valve shown in Fig. 9, outlet pressure via 124 acts on the adjustably loaded diaphragm of a pilot valve 126 to allow diaphragm valve loading pressure in 122 to be augmented from the inlet via 120 or vented to the outlet via 124. The valve 126 may be replaced by interconnected self-lapping valves operated by two diaphragms or the valve 126 may be actuated manually or by a solenoid. The twin diaphragm self-lapping valve replacing 126 may be used in a pressure release valve in which case one diaphragm is exposed to inlet pressure and the other diaphragm exposed to outlet pressure or to atmosphere. In two relief valve applications valve 126 is omitted and pipes 120, 122 and 124 contain variable constrictions and are connected to a common damping chamber, or the pipe 120 may contain a diaphragm-operated pressure regulator leading to pipe 122 and then through a variable restriction either to atmosphere or the outlet. Fig. 12 shows the invention used as a cistern dump valve. Normally the diaphragm valve is kept closed by a loading pressure of a column of liquid 168 supplemented by pressure above the liquid in the system 150 acting through the adjustably loaded self-lapping valve 158. For a given height of liquid in tank 150 the pressure above the column 168 is relieved to atmosphere at 160 by the pressure at the foot of the tank acting on a diaphragm via pipe 154. The diaphragm valve is then forced open by inlet pressure equal to the pressure due to the liquid and the pressure above the liquid. The diaphragm valve closes when the pressure in 154 equals the pressure above the liquid together with the spring loading of the self-lapping valve. The diaphragm valve may be used as a cistern supply valve in which case the pressures in the pipes 154, 156 actuate the self-lapping valve 158 to either supply or exhaust diaphragm valve inlet pressure to or from the line loading diaphragm valve.

Title: Improvements in the apparatus for compressing air, gases or vapours or for producing heat or cold
IPC: F04D17/12
Filed: 1922-10-09
Abstract: 209,478. Vianello, E. Oct. 9, 1922. Multi-stage pumps; balancing moving parts; leakage -preventing devices.-A multi-stag turbine compressor for gases or vapours has a number of blade wheels which successively offer passages of reduced' cross-sectional area to the flow of the fluid. The blade wheels are arranged in two symmetrical sets to balance the axial thrusts; each wheel has a rim projecting towards the suction side and having ports which make an angle of from 50‹ to 60‹ with the radius on the inlet side and pass radially on the outlet side. Atomizers 8 are provided for the injection of water near the suction end of the compressor to form a mixture of steam and water so that it may be condensed under compression in case of an adiabatic compression of wet steam, or to keep the temperature nearly constant in the case of compression of a permanent gas. The casing is divided into cells by diaphragms 15 with packing rings 16 to prevent leakage. The rings 16 are screwed on to the central parts of the diaphragms and may be adjusted in position, relatively to the blade wheels, from outside the casing. The fluid to be compressed' is drawn in the suction pipe 4 and discharged through the pipes 5, 5<1> to the receiver 3, Fig. 1. The total cross-sectional area of the ports diminishes on successive wheel rims from the suction pipe 4 outwards by reason of the diminution in axial length and number of the ports. The lower pressure side of each diaphragm 15 carries deflectors 20 placed radially at their inner parts but inclined about 60‹ to the radial at their outer parts. The compressed gas passes out through the valve 9. Cold water circulates in a nest of tubes in the lower part of the receiver 3 to cool the liquid passing out through the pipe 6, or cooling tubes may be arranged inside the compressor or a cooling jacket placed round it. The packing glands preventing leakage between the casing and the shaft have small wheels 109, 109<1>, Fig. 14, integral with the shaft and shaped like the wheels of the compressor. The wheel 109<1> checks the flow of fluid from the high-pressure side of the gland and the conduit 107 directs the leakage flow from this side to an intermediate part of the compressor; the wheel 109 directs the leakage from the lowpressure side through the conduit 108 to the low pressure stage of the compressor.

Abstract: 845,168. Friction clutches. FIAT S.p.a. Aug. 26, 1958 [Oct. 30, 1957], No. 27362/58. Class 80 (2). [Also in Group XXIX] In a vehicle transmission clutch plates 4, 11 are engaged by the centrifugal pressure of liquid supplied from a tank 41 to a rotatable chamber 45 formed by a casing 17 attached to the flywheel 1, the pressure acting on a piston 14, the rotation of the liquid being stopped to effect clutch release by holding stationary an impeller 22 mounted in chamber 45 and rotated with casing 17 by fluid friction. Stopping of the impeller is effected by energizing a solenoid 31 to brake one member 29 of a normally engaged auxiliary clutch, which is connected to the impeller by dog-clutches 26, 28 and members 23, 27, and to the output shaft 6 through a dog-clutch 35 and a free-wheel clutch 37 effective on over-running of the shaft. Flow of liquid to the chamber 45 is controlled by a differential valve consisting of a resilient annular lipped member 42 provided with a series of apertures 42b, flow into the chamber taking place only through these apertures, the lip 42a being sealed against a member 23, but flow from the chamber, consequent upon rearward movement of piston 14 during clutch release, taking place also through the annular gap formed around lip 42a by its inward deflection.

Title: Process for obtaining cyclic olefins from the corresponding cycloparaffins
IPC: C07C5/56
Filed: 1962-07-17
Abstract: Monocyclo-olefines are produced by dehydrogenating the corresponding cyclo paraffins at 350-550 DEG  C. with the gaseous mixture obtained by reacting hydrogen chloride and oxygen or oxygen-containing gases in the presence of a hydrogen chloride oxidation catalyst (see Division B1) at 350-550 DEG  C., the molar ratio hydrogen chloride: oxygen being between 20:1 and 1:1 and cycloparaffin: oxygen being between 20:1 and 2:1.  The oxidation and dehydrogenation may be carried out either simultaneously in the same vessel or in a reaction furnace divided into two zones, the first zone, to which the hydrogen chloride is introduced, containing the catalyst and the second zone, being either empty or packed with inert material, to which the products from the first zone and vaporized cycloparaffin are fed. Cycloparaffins having 5-8 carbon atoms are specified, e.g. cyclohexane.ALSO:Catalysts for the oxidation of hydrogen chloride may be copper and/or iron salts with the oxides or chlorides of the rare earths and/or alkali metals and/or alkaline earth metals deposited on suitable carriers.  Specified are copper and magnesium oxides on silicaalumina and the product formed by soaking fossil meal in a solution of cupric chloride, magnesium chloride and cerium chloride, drying at 110-130  DEG C. and calcining for 30 minutes at 400-450 DEG C. in a stream of air.

Filed: 1947-10-13
Abstract: 646,655. Fire-alarm systems. STANDARD TELEPHONES & CABLES, Ltd. Oct. 13, 1947, No. 27407. [Class 40 (i)] In a signalling system employing a number of normally ungrounded, series-fed, closed loops, each including a number of transmitters such as Box A, B, and normally energized line relays LA, LB, Fig. 1, the loops are changed over to parallel grounded connection by a relay K during a signalling operation whereby signals from two transmitters on the same or different loops may be recorded simultaneously at a central station as described hereafter. Normal operation, one loop.-On operation of box A, the first breakimpulse makes a circuit at the central station over mc3 down, lar1 up, loop relay contacts la2 down energizing change-over-relay K and relay KA in parallel to stick up over ka1, Fig. 2. Loop relay LB energizes relay KB similarly. (Slow-release fault-detecting relays LAR, LBR normally maintained energized by loop relays LA, LB, do not drop out during breakimpulses.) Change-over-relay K connects the two ends of the loop in parallel and grounds the battery, Fig. 1, whereafter Box A sends the rest of the signal over the ground circuit (switch ES being closed during operation). Each further impulse from the transmitter drops la1, lb1 to make a circuit over ka2, kb2 up for the punching relays PA, PB, which operate momentarily only and are de-energized by RA, RB. With a single loop the energizing circuit for PB may be assumed to run over the chain-dotted line from PB to kb2. Two boxes-one loop.-If Boxes A and B operate simultaneously they will control relays LA, LB respectively in the two parallel arms formed when the loop is changed over and the battery grounded by relay K and hence the punching relays PA, PB will record signals from boxes A and B respectively. Boxes in different loops, e.g. loops 1 and 2.- Relays 21a, 2lb in the second loop circuit (not shown) will operate relays 2ka, 2kb (not shown), as described above for a single loop. Punching- relay PB will be controlled by 2lb1 over 2kb2 up, 3ka3, 3kb2 down, while punching-relay PA follows la1 in the first loop as before. Open circuit fault.-A prolonged break due to loop-open-circuit, releases LAR to energize relay KR which is held up by its second winding and energizes the second winding of relay K to change the loop to parallel grounded connection, whereby signals may be sent as above when a box operates. The fault circuit is released by key RK de-energizing the second winding of relays KR and K. Recording and resetting.-The punching-relays PA, PB energize the paper-feed-motor-relay MS to stick up and start the motor, Fig. 3, which closes cam-operated contacts RC, once a revolution, to energize relay MP. When the punching signals cease, the relay chain MA ... ME is energized in steps over ms3, pa3, pb3 for every closure of mp1, and de-energizes relays KA, KB over mc3 up and finally breaks the motor relay circuit over me3, by which time the perforated paper signal has been fed clear of the punches.
