Title: Improvements in liquid fuel burners
Filed: 1922-03-22
Abstract: 199,780. Dalzell, H. E. March 22, 1922. Spray burners.-In a spray burner of the type in which the liquid fuel and atomizing agent are conveyed by separate passages to substantially rectangular outlets in the burner body, the flow of the fuel and atomizing agent is regulated simultaneously and proportionately by a valve or valves having a port or ports of substantially triangular, parabolic, semicircular, or cycloidal section. In the burner shown in Figs. 1 and 2, the fuel and atomising agent pass along passages a, b respectively in the burner body to chambers a<1>, b<1> at the burner mouth, and the discharge through outlets a<2>, b<2> is regulated by means of two horizontal rotary valves c, d having ports c<4>, d' and provided with interengaging toothed sections c', d<1>. The valve operating mechanism is connected to a shank C<SP>2> on the valve c, and the movement of the valves is limited by stops C<SP>3> on the valve c engaging a projection a<3> on the burner body. The size of the outlets a<2>, b<2> may be regulated by means of an adjustable and removable copper lip plate e which may have a slightly hollowed front face and upper edge. In a modification shown in Fig. 13, interconnected rotary valves o<1>, p<1> are provided with substantially triangular ports o<2>, p<2> which are inverted relatively to those shown in Figs. 1 and 2, and the adjustable lip plate q for regulating the extent of the oil and atomizing agent outlets is inclined. A central projection r formed on or attached to the upper edge of the fuel outlet guides the oil to the middle of the plate q. In another form of burner shown in Fig. 11, a plate valve i having a triangular or other suitable opening i<1> is vertically movable in guides i<2> by means of sector and rack gearing k, k' across the fuel and atomizing agent outlets f<1>, h'. The outlet h<1> is independently adjustable by means of an adjustable and removable plate l forming its lower lip.

Abstract: 1293874 Laminated products UNIROYAL Inc 24 Feb 1970 [26 Feb 1969] 8732/70 Addition to 1034988 Heading B5N A leather-like three-layer laminate comprises a base layer of fabric, an intermediate cellular layer of blown polyurethane and a surface layer of polyurethane, the material of the intermediate and surface layers defining a multiplicity of interconnecting voids to give gas permeability, the voids containing particles of an incompatible thermoplastic resin such as polyethylene, polypropylene or wax. The laminate is made by forming the surface layer, usually on a casting surface such as paper which may be silicone-coated, from a uniform mixture of a fluent polyurethane film-forming material and an incompatible thermoplastic resin, forming on this layer the intermediate layer from a similar mixture but also containing a blowing agent, the incompatible resin in each layer being in a physical form (e.g. powder) having an apparent density less than its actual density, applying a fabric to the surface of the intermediate layer, heating the entire composite to fuse the two layers into a unitary film bonded to the fabric and rendering the body layer cellular by substantially simultaneously decomposing the blowing agent and melting the incompatible material in the two layers. The fabric backing may be knitted or woven natural or synthetic fibres. The minute voids in the polyurethane layers may be made more open by kneading or staking.. The surface of the laminate may be given an overall slip finish in diamond-shaped deposits by means of a discontinuous print roller and may be subsequently embossed.

Filed: 1961-03-13
Abstract: 936,316. Hydraulic transmissions. BERGENS MEKANISKE VERKSTEDER A.S. March 13, 1961 [March 16, 1960], No. 9073/61. Class 69 (2). [Also in Group XXX] An hydraulically driven mooring winch 10 normally powered from a main pump 1 driven by an electric motor 3 is provided with a low capacity auxiliary pump 11 driven by an auxiliary low power electric motor 12 for use in maintaining the ropes taut during tidal movements &c. whilst releasing the main pump 1 for other purposes. The capacity of the auxiliary pump may be variable. A regulating valve 8 maintains a constant pressure in the supply line and thereby maintains a constant pull on the ropes. The auxiliary electric motor 12 is controlled from a pressure-sensitive switch 13 which operates to drive the pump 11 at high speed when the pressure in the system drops so that slack in the ropes is taken up rapidly. A rise in pressure due to tightening of the ropes causes the motor 12 to reduce speed and thereby reduce the power loss at the regulating valve 8.

Abstract: 594,156.  Hand tools for planting. HARRISON, L. D., and QUARTON, C. F. B. April 12, 1945, No. 9112. [Class 6 (ii)] [Also in Group V] Apparatus for use in transplanting seedlings, which is provided with a cutter-open at the lower side for cutting out a clod of soil, with a ram for pressing a hole in the clod, and with a plate for ejecting the clod, said plate being attached to a pair of reciprocable rods, has the upper ends of said rods connected by a crossmember passing through the tool shaft and engaging with a lever-operated plunger axially slidable within the tool-shaft. A shaft 3 has at the upper end a handle 4 and at the other end an open mould 5 of which the lower edge 5a is sharpened to cut into the compost. Mounted to slide within the shaft is a rod 6 carrying a plunger 7, which is pressed into the mould to form a central hole in the block of soil by operation of a lever 11 passing through a slot 12 in the shaft and pivoted on an arm 14 attached to the shaft. A spring 8 restores the plunger to its original position after operation of the lever 11. On depressing a second lever 21, passing through a slot 3b in the shaft and pivoted to a bracket 23 on the shaft, an ejector plate 15 is actuated. The ejector plate 15, which has sliding fit in the mould 5 is provided with a central aperture for the passage of the plunger 7, and is carried at the lower end of two rods 16 vertically slidable in tubular guides 17 and maintained in the rest position by two springs 18. A cross-bar 19 is slotted through the tops of the rods and through slots 3a in the shaft. A plunger 20 inside the shaft abuts against the lever 21 and is slotted at its lower end to pass over the cross-bar 19. Depression of the lever 21 operates the plunger 20 and hence moves the cross-bar 19 and the rods 16 downwards to press the ejector plate 15 against the container and force it out of the mould.

Title: Improvements in and relating to voltage regulators
IPC: H02P9/32
Filed: 1951-04-19
Abstract: 694,756. Automatic voltage control systems; inductances. BRITISH THOMSON-HOUSTON CO., Ltd. April 19, 1951 [May 2, 1950], No. 9180/51. Classes 38 (ii) and 38 (iv). [Also in Group XXXIX] The output voltage of an alternator is controlled by supplying its field from the A.C. output via a rectifier and saturable reactor, the reactor being controlled by a mag. netic amplifier having a permanent magnet as a reference m.m.f. The voltage of the alternator 1 is detected by connecting a resistor 24 and condenser 25 in series across the output to provide a frequency compensated voltage divider, the voltage across the condenser being rectified at 26 and applied to control windings 22, 23 of the amplifier 6 (and also to a biasing winding 38 on reactor 31). The output of amplifier 6 controls the excitation of winding 37 to vary the saturation of reactor 31, thereby controlling the magnitude of the current that flows (in alternate half-cycles) through load coils 32, 33 and rectifiers 34, to the field winding 4. Amplifier 6 consists of a permanent magnet 12 (surrounded by a shorted turn 41 to reduce the effects of a pulsating flux due to the current in the load windings) the magnet being shunted by laminated core members 9, 10, 11, 13, including air gaps 16, 17, and also shunted by two cores 14, 15 of relatively small cross-section, and made of a magnetic material having a very sharp knee in its magnetization characteristic. The flux of the permanent magnet would saturate the cores 14, 15, were it not for an opposing flux due to control windings 22, 23 wound on the cores 14, 15. Load windings 19, 20 are wound on cores 14, 15 respectively (under the windings 22, 23) and, on alternate half-cycles, pass current from a transformer 5 through winding 37 via rectifiers 21. The pulsating flux in core 14 or 15 due to the unidirectional current pulse through winding 19 or 20 aids the flux due to the permanent magnet. Hence at some point on the pulse waveform the total flux causes the core to saturate, the reactance of the winding falls sharply and current is passed to the winding 37. The point at which the core saturates is determined by the control current in windings 22, 23 which controls the degree of magnetization of the cores. In a modification, Fig. 2, the axis of the permanent magnet 12 is parallel to the cores 14, 15, and the main portion of the core comprises upper and lower members 42, 43. A magnetic shunt 44 is inserted between members 42 and 43 and airgaps are included in this path. In a further modification, Fig. 3 (not shown), the core is made symmetrical by placing the cores 14, 15 on opposite sides of the core which contains the permanent magnet. Specification 670,838 is referred to.

Abstract: 1303682 Photographic apparatus EASTMAN KODAK CO 26 Feb 1970 [27 Feb 1969] 9247/70 Heading G2A [Also in Division E2] A latching device 51, e.g. for a photographic camera, is formed as a one-piece plastics moulding or of other like mouldable material and has a hook shaped latching lug 55 which cooperates with a fixed hook shaped latching lug 33 on the camera cover 7. As shown, the camera cover is closed, with surfaces 63 of the device 51 in a lowered position so as to permit movement of film driving member 64 to its lowered position in which it engages a film take-up spool. To open the cover, a knob 53 is raised (as seen) thereby raising the device 51 to disengage the lugs 55, 33. Also, an abutment surface 67 of a flexible release member 57 engages surface 37 of the lug 33 to resiliently urge the cover 7 to a partially open position, Fig. 5 (not shown) where it can be easily grasped by an operator. Additionally, the surfaces 63 raise the film drive member 64 to permit loading or unloading of film. When the cover is fully opened, Fig. 6 (not shown), the member 57 is no longer resiliently flexed, but the surface 67 thereof engages a surface 24 of the camera casing to maintain the device 51 in the raised position. As the camera cover is  closed, the surface 57 is pushed off the surface 24 by the surface 37 to permit lowering of the device 51.

Abstract: 1277435 Valves; pipe couplings WHESSOE Ltd 1 Jan 1970 [20 Feb 1969] 9259/69 Headings F2G and F2V In a coupling assembly composed of coupling and adaptor members 8 and 32, 33, respectively, the coupling member is provided with a closure member 27 biased by a spring 30 into engagement with a seat 29, and the adaptor member is provided with a closure member 35 biased by a spring 44 into engagement with a seat formed on portion 32 of the adaptor. The respective passages through the coupling and adaptor members are maintained closed by the two closure members both when the two members are separate and when the assembly is completed, as by inserting portion 32 within coupling member portion 5 and appropriate swinging of clips 6. Subsequent to completion of the assembly as per above, the flow path through the assembly can be opened by moving lever 14 in a clockwise sense such that, by virtue of the engagement between teeth 16 and pins 18, actuator member 17 is moved towards the right, as seen in the drawing, until it unseats closure member 35 and brings the latter into engagement with a stop 34. Thereafter, further movement of the lever 14 results in the lever bearing on actuator 17, and hence in a movement to the left, as seen in the drawing of the sleeve which surrounds the actuating member and which carries the coupling closure member, the latter movement serving to open the coupling member valve. In the event of the actuator and coupling members being detached, either accidentally or purposely, the two valve closure members are immediately urged to their respective seats by the action of springs 30 and 44. Once detached, the coupling and adaptor members can have dust caps attached thereto (Figs. 1 and 2, not shown). The free portion of the coupling member duct is rotatably attached to an inlet pipe (2, Fig. 1).
