Title: Flow regulating valve mechanism
IPC: B62D5/07
Filed: 1966-10-31
Abstract: 1,132,510. Motor vehicles. NEW YORK AIR BRAKE CO. 31 Oct., 1966 [21 Feb., 1966], No. 48695/66. Heading B7H. [Also in Division F2] An hydraulic circuit in a motor vehicle for operating an implement and power steering comprises three pumps, P 1 , P 2 , P 3 , drawing fluid from a reservoir 15 and driven by an engine 14, the output from P 3  being delivered directly to the implement circuit 13 through a line 18 and the output from P 1  being delivered to a valve device 11 through which it passes via an input 22, shuttle valve 27 and line 17 to a steering circuit 12. The output from P 2  passes through a line 19 and into the valve device 11, where, below a predetermined engine speed, it flows past a valve spool 35 and through channels 38, 24a and through radial orifices 29 in the shuttle valve 27 to supplement the flow from P 1  in the steering circuit. The shuttle valve 27 is biased to the left by a spring 31 and has an axial bore from which extend the orifices 29 and a replaceable pair of flow restricting orifices O 1  and O 2 . The valve spool 35 is biased to the left by a spring 42 and has internal passages 46, 47 for transmitting fluid pressure to its left face 45, its right face 33 being subjected to the pressure in passage 26 downstream of the valve 27 through a passage 49. The line 19 from P 2  enters the valve device 11 at a chamber 24 from which channels 39 and 24b extend in parallel with channels 38, 24a, channel 24b leading through a chamber 25, closed by a check valve 51 to a line 21 connected to the implement supply line. Up to a certain speed of the engine, P 1  and P 2  jointly supply the steering circuit and P 3  the implement circuit. Beyond a certain pressure gradient across the orifice O 1 , the pressure in channel 24a acting through passages 46 and 47 causes valve spool 35 to move so that an orifice 03 begins to close while an orifice O 4  opens, allowing fluid to enter channel 24b. Over a certain range of speed, the combined outputs from P 1  and P 2  to the steering circuit remain constant while part of the P 2  output is added to the P 3  output in the implement circuit. At a further predetermined speed, the pressure build-up on the face 27a of shuttle valve 27 causes it to move to the right against the pressure of spring 31, to a position beyond the channel 24a. The pressure gradients across O 2  and O 1  now act in series so that the relative pressures on the faces 45 and 33 of valve spool 35 causes the orifice O 3  to be closed so that the total outputs from P 2  and P 3  are directed to the implement circuit while the steering circuit is supplied solely by P 1 . The variable parameters determining the various speeds are the orifices O 1  and O 2  and the springs 31 and 42. There may be a slight initial drop of pressure in the steering circuit at engine speeds above that at which the orifice O 3  closes.

Abstract: 1,172,823. Fuel cell gas supply system. ENERGY CONVERSION Ltd. 8 Nov., 1966 [17 Nov., 1965], No.48952/65. Heading H1B. A fuel cell system uses the pressure energy of pressurized fuel to cause oxidant to flow to the cell. As shown, pressurized fuel gas, e.g. hydrogen, in a cylinder 10 is expanded in a cylinder 15 to cause reciprocation of a piston 16 and a connected piston 22 of an oxidant (e.g. air) pump 23, the expanded gas being expelled from the cylinder 15 through a line 17 leading to the fuel electrode chamber of a fuel cell 19 and the pumped oxidant passing through a line 29 to the oxidant electrode chamber of the cell. The fuel gas passes through a pressure reducing valve 11 and a control valve 12 responsive to the pressure in the line 17, thereby to maintain the required pressure in the fuel cell. Should the pressure in the cell exceed a predetermined value the fuel gas is vented through a valve 35 and either burnt in a catalytic burner 36 or recovered for subsequent use in the cell. To ensure that the correct amount of oxidant is supplied to the cell for all operating conditions, the supply from the pump 23 may be divided into two streams by a valve, Fig. 2 (not shown), under the control of a device responsiveto changes in the humidity or electrolyte strength within the fuel cell. One stream leads into the cell and the other stream by-passes the cell.

Abstract: 1,164,305. Laminating apparatus; foamed laminates. IMPERIAL CHEMICAL INDUSTRIES Ltd. 2 Nov., 1967 [10 Nov., 1966], No. 50473/66. Heading B5N. Apparatus for the continuous manufacture of a laminate, having a foamed plastic layer bonded to at least one facing sheet in the form of discrete panels, comprises means for conveying sheets and means for applying foam thereto, said means for conveying sheets in the form of discrete panels including means whereby panels fed at random intervals are caused to move so that their adjacent edges are brought into abutment before foam is applied to the panels. Preferably, the conveying means comprises a main conveyer preceded by a register conveyer on to which panels are fed, the main conveyer being driven at constant speed and the register conveyer being driven at a speed which varies in a regular manner such that while a panel is engaged by both conveyers their speeds are identical, but when the panel is disengaged by the register conveyer the speed of this conveyer is increased for sufficient time to bring the following panel into abutment with the other panel. As shown, the foamed core 13 is formed between two facing layers in the form of panels, conveyed by main conveyers 1, 2, register conveyers in the form of endless chains 18, 41 and feed conveyers 31, 51 on to which panels are loaded. The main conveyers are driven by motor 6. The register conveyers are coupled via variable speed gear-box 21 to epicyclic gearbox 22 driven by inputs (i) from motor 6 and (ii) from motor 24 via constant torque eddy current coupling 25, the latter operating when the load on the register conveyer is reduced. The speed of conveyer 31 is synchronized with conveyer 18 by the output of tacho generator 36 controlling constant torque eddy current coupling 35 on the drive from motor 34. Conveyer 51 operates by gravity. In the position shown, conveyers 1, 2, 18, 31 and 41 move at the same speed until the lugs 27, 44 engaging panels 12, 38 move down and are disengaged therefrom. The load on conveyers 18, 41 decreases, and the constant torque causes them to accelerate; lugs 28, 45 now engage panels 29, 47 and urge them forward into abutment with the preceding panels, whose resistance then restores the load on the register conveyers to its previous value. Spacing members may be clipped to the lower panels to compensate for variations between lengths of upper and lower panels. The foam may be polyurethane foam. Facing materials may be paper, wood, plastics, metal, rubber, paperboard, plasterboard, or asbestos cement board, the apparatus being particularly suited to those more rigid materials available only in panel form.

A thrust ring 13 is axially movable with respect to the shaft 9 by means of a forked arm 17, which also prevents its rotation, the arm being operated by a hand-brake lever (not shown) via a shaft 16. Movement of the thrust ring axially also moves the rotor and thereby the lining 7 into engagement with the drum, against the force of a return compression spring. In addition an annular friction lining 15 on the ring engages a portion 14 of the rotor m the manner of a disc brake. The application to amphibious vehicles is described wherein the brake unit is sealed against ingress of water. The unit may be attached to a speed change gear-box (Fig. 6b, not shown) or to a distributer transmission unit (Fig. 6a, not shown) in a four wheel drive vehicle; or to the speed change gear-box of a rear-engined car (Fig. 6c, not shown) or front-engined car (Fig. 6d, not shown).

Abstract: 1278385 Electro-deposition of paint FORD MOTOR CO Ltd 30 Oct 1970 [24 Dec 1969] 51640/70 Heading C7B In the electro-deposition of paint on a workpiece, a fraction of coating bath liquid extracted from the bath and having a paint concentration less than 50% of that in the bath is used to rinse the workpiece, rinse liquid being returned to the bath. As shown, article 19 is in electrical contact with bus-bar 37 via 25, making article 19 anodic whilst immersed in coating bath 13. Tank 11 is cathodic, as is also porous metal container 41; thus cations from the coating bath are attracted through waterpermeable membrane 43 (of cloth, plastics, metal or porous ceramic) so that a paint-solids-poor aqueous, dispersion forms within separation unit 40. This dispersion is pumped via 45, conduit 49 and spray heads 55 and 57 on to an article 27 which has emerged from the bath 13. The paint used may be a polycarboxylic acid resin binder dispersed within a water-soluble base, e.g. a soluble amine, ammonia, KOH, LiOH, or NaOH; an impressed potential of 50-500V and a 5-15 wt per cent resin concentration are used. It is also possible to use a cathodically depositable resin; in this case container 41 must be anodic, as must tank 11; the workpiece is cathodic.
