IPC: H05B3/68
Filed: 1947-01-20
Abstract: 621,926. Induction heating apparatus. SHAW, H. N. Jan. 20, 1947, No. 1799. [Class 39(iii)] The upward force on an electrical induction heated container 10, produced by the currents flowing in the primary coil 25 and the secondary coil 15, is balanced by magnetic pads 29, Fig. 5, located between the top of the primary coil and the adjacent face of the secondary coil. The secondary coil 15 is contained within a laminated magnetic frame 13 extending below the container base, and is positioned, together with the insulated primary coil 25, between the legs of a U-shaped laminated magnetic ring 17. The pad 29 comprises a number of magnetic steel strips 31 secured to non- magnetic saddles 30 held in slots within the main ring 17. Air gaps 32, within the pad, may be varied to produce the required downward force. The container 10 may rest on three non-magnetic pads, not shown, placed between pairs of pads 29 equally spaced around the ring 17. Specification 440,105 is referred to.

Void [Abridged as open to inspection under Sect. 91 of the Acts, July 26, 1935]. [Class 102 (i)] In a fuel - injection pump, of the type in which the suction and discharge ports are controlled by the plunger b and the injection is effected by an accumulator piston c loaded by fuel compressed in a chamber d, the chamber d is enclosed in an outer casing e into which the fuel supply pipe o opens. During the suction stroke of the plunger b fuel is drawn from the casing e into the container d through a check valve h and passes to the pump through passages p. Trapped air is discharged from the casing e to an escape pipe w through an annular space r<1> and a valve u opened by means of a press button s. Depression of the valve u also depresses the valve h, thus permitting escape of air from the container d. In a multi-cylinder pump all containers d are enclosed in a common casing e. The spindle of an air escape valve in the casing e carries tappets which open the valves h of the containers d.

IPC: B41J29/15
Filed: 1927-01-24
Abstract: 264,880. Zukmann, L., (Assignee of Schmidt, F. P.). Jan. 23, 1926, [Convention date]. Copy-holders.-A copy-holder is provided with a manuscript carrier, preferably an endless band, which is advanced for line-spacing. The support shown in Fig. 1 comprises two side members 2 connected together by transverse bars 3, 4 and carrying upper and lower rollers 5, 6 over which passes an endless band 7 tensioned by a weight 8. The manuscript supported on the band 7 rests with its lower edge against a ledge 9 attached to the band, and is held by spring clamping-fingers 11 mounted on the ledge. A resilient stop 10 is provided on the ledge for contact against the rollers 5, 6 to determine the limits of movement. An extension table 14 is mounted on the upper bar 3 and can be supported against a stop 15 either as a continuation of the band 7, or in the lower position 14a, or can be turned down as shown at 14<b>. A line indicator 16 is adjustably mounted by means of a slotted arm 17 on one of the side members 2 for use either over the band 7 or over the extension table 14. The band 7 is advanced for line-spacing by means of a key 27 and pawl-and-ratchet mechanism comprising a wedge-shaped pawl 24, Fig. 3, on a yoke 23 connected to the key-lever 26, and a V-grooved wheel 22 on the shaft of the lower roller 6. An adjustable stop 30 determines the extent of the linespacing feed. A detent pawl 32, Fig. 1, for preventing reverse rotation of the wheel 22, is connected with a release key 34. When the key 34 is depressed, both pawls 34, 24 are released, through a connection 35, and the ledge 9 is returned against the lower roller 6 by gravity, or by the aid of a spring drum connected with the roller 6. The ledge 9 may be provided with lateral guiding lugs extending over the side members 2. The feed mechanism for the roller 6 may be provided as a separate unit connectible by a flexible shaft, in which case wider manuscript extending beyond both sides of the support may be used, and the line indicator may be made extensible. Fig. 6 shows a separate feed unit mounted in a casing 45, the keys 27, 34, the adjusting screw 31 for the line-spacing stop, and the feed shaft 21a projecting externally. The shaft 21a is provided with a stop device for locking the movement in either direction and preventing overwinding of the spring drum. This stop device comprises stops 40, 41 on the shaft and co-operating stops 38, 39 on a nut 37 travelling on a screw-thread 36 on the shaft. A detent 42 sliding on a guide 44 prevents rotation of the nut 37 and can be released to permit adjustment of the spring tension.

Title: Improvements in electrode assemblies for the electrolytic protection against corrosion of metal structures
Inventor: MORGAN JOHN HAROLD
IPC: C23F13/02
Filed: 1959-01-20
Abstract: 866,577. Preventing corrosion. STURTEVANT ENGINEERING CO. Ltd. Jan. 20, 1960 [Jan. 20, 1959], No. 2082/59. Class 123(1) An impressed current anode assembly for the cathodic protection of liquid-containing metal vessels, especially the tanks of oil tanker ships carrying sea water ballast, consists of a rod 1 of titanium, tantalum or other metal on which an anodic film is formed covered at its mid-portion with a layer 5 of platinum or other metal not affected by the electrolyte and forming the anode proper. The rod 1 passes through an insulating bushing 2 in the tank roof and is connected to a source of direct current. The lower end of the rod terminates a short distance from the tank bottom and is held in an insulating block 3. In operation, the anodic film on the rod prevents flow of current therefrom into the sea water electrolyte. When oil is fed into the tank any electro-static charge carried by the oil in the vicinity of the rod 1 discharges through the film which is conductive with respect to electrostatic potentials. Consequently, when the level of the incoming oil reaches the anode 5 no discharge spark occurs.

As illustrated the second or outer portion 7b is rigidly connected to support arms 11-13 pivoted at 14-16 on the side wall 1 of the container. The first or inner portion 7a of each part includes at each end a roller 20 which is movable in a guide (19), (Fig. 6, not shown), and which constitutes said movable means. The biasing means comprises torsion bars 17, 18 which are each clamped at one end to the side wall and attached at the other end to the arms 11, 13 respectively. Twisting of the bars during opening of each roof part opposes the weight of that part. Cover plates 10, (21), (Fig. 6, not shown), are provided for protecting the hinges 9 and guides.

Class 135 Means for regulating' the supply of air to a furnace comprises: pressure responsive members respectively connected to the fuel and air systems; actuating means for varying the air supply corresponding to the supply of fuel; and relay mechanism controlling the motive power to the actuating means including a rotatable element connected to the pressure responsive member in the fuel system and formed with a portion whose curvature is dependent on a predetermined relation between the air and fuel pressures, and means co-operating with the curved portion and connected to the pressure responsive member in the air system. The supply of combustion air to a furnace burning liquid or gaseous fuel from a ring main at 01, 02 is controlled automatically by a piston 4 which adjusts the steam valve V of a motor driving a fan F. Pressure fluid is supplied at 10, Fig. 2, to each side of a relay double-acting piston or diaphragm 14, 15, connected to two jets 12, 13, the outlets from which are controlled by a law plate 16 carrying a slot or cam 26. The jets are moved by a diaphragm 22 responsive to the fan outlet pressure at 24 while the plate is rotated by a diaphragm 18 responsive to the pressure of the fuel at 20 in the return pipe R to the fuel pump. The piston 14, 15, actuates a valve 8 by which fluid pressure supplied at 9 actuates the piston 4. The fuel return flow is regulated by an automatic pressure valve A in the return pipe responsive to boiler pressure or temperature. In a modification the boiler pressure or temperature acts through an air pressure controller, the diaphragm 22 is responsive to pressure in the furnace and the piston 4 actuates dampers in the furnace exhaust. The slot 26 and diaphragm 22 may move a lever and cam for operating flaps controlling the jets. The draught regulator may be actuated by electric motors controlled by an electric contact controller.
