Title: Improvements in or relating to the manufacture of sectional heat-exchangers
IPC: B21D53/04
Filed: 1949-03-03
Abstract: 673,071. Radiators for heating and cooling buildings. BINDER, H. G. March 3, 1949, No. 5875/49. Class 64(ii) A sheet metal heat-exchanger, e.g. a central heating type radiator for the flow of heating or cooling medium, or section thereof, has bosses which fall away substantially perpendicularly, as at n in Fig. 7, to the edge of the section and which have, located wholly or partly therewithin, parts i each internally threaded and rigidly brazed or welded to the front m of the boss. The sections of the radiator are formed by the welding together of flanges k at the edges of half sections and the annular, threaded parts i are used for plugging, for tightening by right- and left-hand threaded nipples, and for connecting to pipes. The bosses, in cross-section, may be circular, or may be generally triangular, or heartshaped as shown in Fig. 8, to provide a flat portion n which is parallel to the edge of the flange k to impart rigidity. The threaded part i may have an annular neck portion protruding through and fitting in the boss aperture, or may be located, for welding, by a plug fitting in this aperture. A flange p of a thickness, viz. 3/16 inch or less, comparable to that of the sheet metal may be provided on the part i, to be welded to the inner or outer face of the boss front m. The shape of the boss in Fig. 8 enables electrodes to be inserted in the corners thereof for spot welding of the flange at points s. In a modified form of part i, lugs are formed at the points s for locating the part and for spot welding to the boss, in addition to welding by a seam surrounding the boss aperture. The welded seam is produced by roller-welding or by using a cup-shaped electrode, Fig. 9, (not shown), in which the part i is supported by its flange p. The boss of a radiator halfsection is fitted over the electrode and an upper electrode is moved stepwise, by a ratchet ,in a circle round the boss aperture in order to stitch-weld the components together. or the cup electrode is moved around the axis of the stationary upper electrode. Specifications 385,608; 495,445, 511,522. 540,051 and 541,497, [Group XXII], are referred to.

Title: An automatic method of taking and recording radio directional bearings
IPC: G01S1/02
Filed: 1931-02-27
Abstract: 375,372. Wireless signalling. FARNES, G. H., 37, Sutton Grove, Sutton, Surrey. Feb. 27, 1931, No. 6159. [Class 40 (v).] The critical readings in wireless directionfinding are recorded by a stylus 7 on a drumchart 2 mounted on the shaft of a rotating frame-aerial, or the search-coil of a radiogoniometer. The stylus is controlled through a relay 5 by the amplified current from the detector valve RR, which is biased to saturation at 5-10 milliamps. As the search-coil and drum 2 are rotated, the stylus traces a straight line until the " minimum " position, when a " dip " is recorded. A spring-controlled rack engaging the shaft of the drum, and controlled by the knob 3, allows the chart to be moved up or down relatively to the stylus so that several successive records can be taken. When taking bearings from a rotating beacon-transmitter, the drum 3 is arranged to be driven by a motor, at the same speed as the beacon, and starting on receipt of the characteristic " North " signal. In the presence of continual jamming, a " clear " interval of one-fortieth of a second is sufficient to enable the critical " minimum " to be recorded. Specification 363,374 is referred to.

Filed: 1927-03-07
Abstract: 274,382. Nielsen, F. March 7, 1927. Vulcanizing boots &c.-The invention relates to a process and apparatus for the vulcanization of rubber soles to fabric uppers, and is characterized by the following principal features, viz. :- (1) the insole and upper are stitched or riveted together except at the heel and toe before lasting; (2) the vulcanization is effected on the last upon which the boot is first mounted for lasting; (3) the upper is under observation during the vulcanization; (4) the sole is vulcanized by heat simultaneously applied to both sides of it. The apparatus comprises a hot-plate 17 on which the sole mould is mounted and a last 23 attached to an arm 22 pivoted at 56 to a bracket 19. The last drops into contact with the mould upon pressure on the pedal 26 counteracting the tension of the spring 24, which normally tends to withdraw the last from the mould, and is held in place by a catch 27; after vulcanization the catch is released and by means of the cords 61, 62 and overhead lever 60 the arm 22 is thrown over through an angle of 180‹ bring- ing the last into a reversed position to enable the boot to be stripped from it. A link 33 ensures parallel motion of the last as it approaches the mould. The last, as shown in Fig. 7, has a separate heel portion 35 forced into position by means of the lever 36; its lower surface has a, cavity containing a double diaphragm 30 to the interior of which steam or hot air is circulated through pipes 38, 39. A loose steel insole 31 is interposed between the diaphragm and the boot. The sole mould, as shown in Fig. 8, consists of a sole plate 41, side pieces 43 surmounted by a thin plate 44 which projects slightly over the edges of the sole, and guide plates 45; it is closed up by means of a rack and pinion gear operated by the lever 51, Fig. 1, and shown in detail in Fig. 4, and is simultaneously pressed into contact with the hot-plate 17 by wedges bearing against the shaft 49.

Title: Improvements in or relating to induction furnaces
IPC: H05B6/16
Filed: 1948-03-01
Abstract: 656,730. Induction furnaces. ELECTRIC FURNACE CO., Ltd., and SPANSWICK, J. R. March 1, 1948, No. 6459. [Class 39(iii)] An open-topped, low frequency electric induction furnace for heating molten metal has a removable immersion element arranged to be lowered into the container without the necessity for liquidtight joints between the element and the container, the element embodying at least part of a magnetic core to increase the effective coupling between the primary exciting winding and the metal to be heated. As shown in Fig. 6, the removable immersion element comprises a rectangular hollow refractory block B having one or more channels C extending through it and containing a magnetic core D energized by a single or three-phase primary winding E, the said channels extending between the limbs of the core D. The molten metal in the channels C provides the greatest resisttance to the current flow but the immersion element B and the furnace A may be so dimensioned that between them they form an additional channel F in the circuit through the molten metal, the dimensions of this channel being adjustable by varying the position of the immersion element to vary the effective impedance of the furnace. The immersion element is preferably open at the top to give access to the windings and the magnetic core, and to facilitate the supply of current and cooling air. The refractory block B may be built around a metallic structure to form an earthed shield between the molten metal and the primary winding.

Title: Apparatus for gauging and sorting
Inventor: SCHWARTZ MORRIS ALBERT
IPC: B07C5/08
Filed: 1957-02-26
Abstract: 835,288. Sorting by gauging. ETHICON Inc. Feb. 26, 1957, No. 6475/57. Class 106 (2). Apparatus for gauging a cross-sectional. linear dimension of a rod-like article S which may vary throughout the length of the article and sorting the article into a class with reference to that dimension comprises means for gauging the article throughout at least part of its length, and devices A2, B2, C2 controlled by the gauging means to sort the article in accordance with its size. As shown in a machine for sorting sutures according to their diameter, the sutures S are passed between wheels 11, 11<SP>1</SP>, the lower one, 11, of which is rotating clockwise as viewed in Fig. 1, gripped by them and passed between gauging wheels 12, 12<SP>1</SP> and on to a further pair of wheels 13, 13'. They are then delivered into a tube 32 and thence propelled along a further tube 37, by a stream of air, to a sorting head 38, Fig. 3, where they are passed into one of four tubes A1, B1, C1, R1 and so into semi-circular receptacles 48. Gauging into the various classes is performed by the movements of the wheel 121 which actuate switches A8, A9, B8, B9, C8, C9 according to the diameter of the suture. These switches operate relays A3, B3, C3 to control the movement of gates A2, B2, C2 in the sorting head 38, after a suitable time lag. The tubes A1, B1, C1 R1 end in chambers A5, B5, C5, R5, closed at one end and provided with gates 42, operated by air motors 49, which may close the undersides of the chambers, but which are normally open. Should a suture be directed to the chamber B5, as shown in Fig. 3, then gate B2 remains open and gates A2, C2 close, as does the gate 42 to chamber B5. After a further time lag, the gate 42 opens and the suture is dropped into the receptacle 100. An electric circuit (not shown( is described, which controls the operation of the various devices, ensures that gates A2, B2, C2 remain in their sorting positions even if a further suture is being gauged, and ensures by means of switches 55, 56 operated by wheels 11<SP>1</SP>, 13<SP>1</SP>, that a suture being gauged lies under all three wheels 11<SP>1</SP>, 12<SP>1</SP>, 13<SP>1</SP>. Electric counters A7, B7, C7, R7 are operated by the circuits to air motors 49.

Abstract: 1348611 Locks JEGA FRIEDRICHSTHALER EISENWERK JENEWEIN & GAPP GmbH 11 Feb 1972 [11 Aug 1971] 6568/72 Heading E2A [Also in Division F4] A self-cleaning electric oven 1 comprises heating elements 2, 3 which are selectively set by a manually actuated switch 28 either to a selected operating temperature or to a temperature at which a self cleaning operation takes place, a door switch 10 which allows the self cleaning operation only when the door is closed, a door fastening mechanism with a locking member and a temperature responsive device which comprises a heat expandable agent and an actuator and which is operative when the switch 28 has been set for the self cleaning operation and the oven has attained a safe limit temperature of 300‹C wherein operation of the device causes the actuator to secure the door fastening mechanism in the locking condition and to set a control switch 22 to close an auxiliary current circuit to effect further energisation of the heating elements to heat the oven to the self cleaning temperature the auxiliary current circuit being independent of the current circuit for the heating elements. The door fastening mechanism comprises a pair of levers 13 pivoting on a support strip 15 on the oven, the levers being urged by springs 17 so that inwardly bent ends secure a pin 5 on the door between them, the levers being locked by a head member 20b at one end of a piston rod 20a of a hydraulic cylinder actuator 20 the member being insertable between the levers to lock them in position. A slide 6 slidable on the oven is moved against the pressure of a spring 7 when the door is closed to operate the switch 10 in a circuit for a heating element 26b surrounding a vessel 26a containing fluid and which is connected by a tube 26c to the cylinder. At about 300‹C a temperature sensor 34 in the oven completes the circuit for the heating element 26b. As the fluid is heated the rod 20a moves and inserts the head member 20b between the levers to lock the door and a stop 20c on the rod 20a closes the switch 22 for the heating circuit for the oven to be heated to the self cleaning temperature. If the sensor controlled circuit fails and the door pin is not locked by the head member 20b it is locked by the deformation of bimetallic elements between the head member and a stop 15a on the support strip 15. Alternatively the rod 20a may pass through a U-shaped metallic spring which deforms when heated to engage behind the head member and move it to locking position.
