Title: Improvements relating to radiators and like heating and cooling apparatus and in the manufacture of the same
IPC: F28D1/00
Filed: 1919-02-14
Abstract: 142,933. Smith, H. R. Melland-. Feb. 14, 1919. Honeycomb and like tube apparatus. - In heat-interchanging apparatus such as radiators for heating buildings, honeycomb radiators for motor-cars, &c., an electrolytically - deposited multi - tubular cell d, Fig. 1, is joined integrally with the other portions of the apparatus, such as the header a, sump b, and inlet and outlet connexions e, f, so as to produce a complete radiator or radiator section. The process consists in joining the multi-tubular core of fusible metal on which the deposit is to be made to the headers &c. by soldering or brazing so as to produce a continuous metallic joint, depositing the metal over the whole, and subsequently removing the metal of the core by melting. The core on which the deposit is to be made is preferably made by running the fusible metal in a molten condition into a mould, comprising a base h and a lid k, Figs. 6 and 8, each having a series of holes i into which a number of removable pegs m corresponding with the tubular parts of the cellular structure are fitted. The core is then joined to the aluminium or other metal header and sump &c., and forms the cathode in an electrolytic bath of which the anode is formed by a series of metal pegs r, Fig. 11, projecting through the holes of the core and held between conducting-plates q of aluminium. The fusible metal core is finally removed by immersing the whole in molten metal at the correct temperature, or by means of a muffle furnace. The complete radiator may consist either of a single section as produced or of several sections bolted together.

Title: Improvements in electric tachometers
IPC: G01P1/04
Filed: 1945-02-13
Abstract: 594,144. Speedometers. WILLS, F. P. Feb. 13, 1945, No. 3623. [Class 106 (iii)] The invention relates to electric tachometers of the type in which a conductive element is mounted for angular movement against spring restraint and extends into anannular gap presented by an electromagnetic stator in which a rotating magnetic field is excited by an alternating current generator. Temperature compensating means is provided, either bridging the annular gap or the interpole spaces. According to the invention, a member or structure of material of which the magnetic permeability decreases with increase of temperature, positions two separately formed iron portions of the electromagnetic stator to present between them the annular gap into which the spring-restrained conductive element extends, and bridges said gap and also the spaces between adjacent polepieces of the stator to afford temperature compensation. In one embodiment a conductive disc 11, Fig. 1, is rotated on a spindle 12, carrying a pointer 26, against the action of a spiral spring 28, by a rotating magnetic field excited by coils 17, Figs. 1 and 2, surrounding polepieces 16 of a stator, the two portions 14, 15 of which are held together by bridge members 19 formed from temperature - compensating material. Castellations 22 formed on the bridge member fit tightly between.the polepieces 16, 18. In another embodiment, a cup-shaped conductor 51, Fig. 3, moves in a gap between an annular portion 55 of the stator having coils 57 on its polepieces and.a central portion 54 connected by a temperature-compensating bridge 59.

Title: Speed control of induction motors by means of mercury vapour frequency changers
IPC: H02M5/27
Filed: 1933-02-07
Abstract: 397,768. Frequency changing. ENGLISH ELECTRIC CO., Ltd., 28, Kingsway, London, CALVERLEY, J. E., Crescent Road, Rowley Park, Stafford, and BALL, R. D., Phoenix Works, Bradford, Yorkshire. Feb. 7, 1933, No. 3708. [Class 38 (ii).] The secondary 3b of an induction motor 3 is connected through a transformer 4 to a mercury vapour rectifier 5 which supplies direct current to a grid-controlled mercury vapour rectifier 6 connected through a transformer 7 to the mains 1. The grids 6c of the rectifier 6 are controlled by a contact arm 9a connected to a battery 8b, and driven by a synchronous motor 10 connected to the mains 1, the contact arm 9a co-operating with contacts 9b connected to a battery 8a, and the grids 6c. Current is thus returned to the supply 1 from the secondary of the motor, the speed of which is varied by moving a member carrying the contacts 9b, or by varying the position of the contact arm 9a on its driving shaft. Alternatively, the phase relation between the supply 1 and the supply to the motor 10 may be varied. The transformer 4 may be constructed as an induction regulator. In place of a contact arm 9a and batteries 8a, 8b, an impulse generator or synchronous peaked-wave alter. nator driven by the motor 10 may be employed. Alternatively, impulses may be applied to the grids by a transformer supplied from the mains 1 and producing a peaked-wave form of voltage, the transformer being constructed as or used in conjunction with an induction regulator. If it is desired that current shall pass from the supply to the secondary of the motor, grids are provided in the rectifier 5 controlled in accordance with slip frequency by methods similar to those used for the grids 6c.

Title: Granulating device
IPC: B29B9/06
Filed: 1965-01-28
Abstract: 1,100,841. Extrusion granulators. BUSS A.G. 28 Jan., 1965 [1 Feb., 1965], No. 3740/65. Heading B5A. Plasticized material fed, e.g. by a screw 2, is extruded through substantially radial nozzles 6 in a truncated conical die 5 and the material is granulated by knives 14 which contact the die and are attached to a housing 11 positioned coaxially with screw 2 and rotatably mounted via bearings 9, 10 on a shaft 8. The nozzles 6 are heated electrically or by the passage of fluid through inlet 12 and duct 7. Cooling fluid is introduced via duct 18 in housing 11 and emerges through nozzles 19 adjacent knives 14, see also Fig. 2 (not reproduced). Fan blades 15 attached to the knives create an air flow within a collector 20 which assists removal and cooling of the granulate. The cooling fluid also provides a film on blades 15 and collector 20 which prevents sticking of the granulate thereto and the collector may be additionally sprayed by liquid entering nozzles 25. The knives 14 are axially adjustable by rotation of a nut 23 which moves housing 11 with or against the action of a spring 22 and the adjustment may be periodic utilizing a drive (11b), Fig. lb (not shown), and linkage 11c to give the knives an oscillating axial movement. In this case die 5 is cylindrical, see also Fig. 1a (not reproduced). The two knives 14 shown may be axially staggered so that each operates on a half of the die 5 or, alternatively, more than two knives may be used. Also an independently driven fan 15a, Figs. 2a and 3 (not shown), may be utilized which surrounds the knives. An additional air stream to cool the granulate and also to effect exhaustion may be incorporated by the provision of a fan (20a), Fig. 3 (not shown), external to collector 20 and having an exhaust (20b). The right-hand side of collector 20, Fig. 1, has detachable flange portions 26 to facilitate cleaning.

Title: An improved method and machine for moulding bodies of granular material
IPC: B28B3/12
Filed: 1920-02-09
Abstract: 162,423. Norton, C. L., and Refractories Machinery Manufacturing Co. Feb. 9, 1920. Processes; endlesschain machines; feeding; templets; delivery. -Silica bricks composed of granulated ganister rock or materials having similar characteristics are made by dropping a quantity of the granules into a mould, the conditions being such that the granules in dropping separate slightly so as to constitute a closely assembled but discrete aggregate on arrival within the mould. The moulds M, Figs. 1 and 3, are carried by endless chains A<1>, passing round sprocket-wheels A<2>, A<3>. The joints of the links are provided with rolls M<5> supported where necessary in their travel by rails F<1>, F<3>. The moulds M comprise a box-like frame M<1> with partitions M<3> and a bottom M' adapted to slide relatively thereto; the spindles of bowls M<6> on the bottom sliding in slots M<7> in the box-like portion. The moulds first pass over a supporting-beam F<2> and the charge of material is dropped into them. The charge of material, which must be more than sufficient to fill the mould, is contained in a hopper D', Fig. 4, provided with sliding gates on arms D<4> which are operated intermittently to allow the charge to fall down a shoot D<2> into the mould. The shoot is larger in cross-section than the mould, so that only freely-falling material enters the moulds. The excess material acts to tamp the material into the mould. The filled moulds then pass on, the lower edge of the shoot scrapes off some of the excess material, and a roller H smooths and presses the remaining material. The material is next subjected to a trowelling action by bars E' and plates E<2> carried in a frame E<3> hung on flexible supports E<4> and given a vibratory movement across the machine. The moulds in passing round the sprocket A<3> are provided with pallets P fed from a slide F. They are held in position on the moulds by a belt B. The pallets may be fed automatically, the mould as it passes pushing on one side a spring catch which retains the lowest pallet in the slide. The pallets then pass on to a supporting-belt C moving at the same rate as the chain A<1> and the bowls M<6> on the bottoms of the moulds, now inverted, engage a rail G and are depressed relatively to the rest of the mould to push the bricks out of the moulds and leave them on their pallets on the belt C. Specification 3726/96 is referred to.

Filed: 1929-02-06
Abstract: 325,377. Fawcett, Ltd., T. C., Fawsett, D. L., and Bottomley, A. E. Feb. 6, 1929. Stationary-moulding machines.-In a screwoperated vertical plunger or like press means are provided whereby on the attainment of a predetermined downward pressure on the brick an upward pressure is applied to it. As shown, the upper cross-head c and the lower cross-head i are connected by guided bolts i, to form a. rigid framework capable of vertical movement, the weight of which is partially supported by springs s. The upper plunger f, carried on the guide member f<1>, is depressed by the action of the screw e engaging with the nut d, thereby applying a top pressure to the clod t. When the frictional resistance of the clod on the sides of the mould k is sufficient to prevent further downward movement of the plunger f, the continued rotation of the screw causes the frame c, i, j to be raised, thereby bringing the abutments j<1> on the lower cross-head into contact with the bottom mould plate m, and transmitting an upward pressure to the clod. The plate m is connected by bolts n to a plate o which is supported on bolts p fixed to the upper cross-head. The screw e may be rotated manually or by means of friction discs g, h.

Abstract: 744,374. Making electrical induction heaters. GENERAL ELECTRIC CO., Ltd., and FRANKLIN, D. C. Feb. 10, 1954 [Feb. 12, 1953], No. 4012/53. Class 83 (2). A method of making a metal article, e.g. a heat exchanger or a work-loop for an electric induction heater, having an internal bore or bores comprises forming in a plaster-like material grooves or ducts, casting a low melting point alloy into said grooves or ducts, removing the plaster-like material from the casting, building up metal on the casting, and removing the low melting point alloy. In an embodiment for making a work-loop for heating the root and one flank of gear teeth a thermoplastic separator 10 is pressed against the gear teeth 11 and a block of plaster-like material 13 is cast into the mould formed by the separator 10. Grooves or ducts 14, 15 are cut in said block and a low melting point alloy is poured into the grooves. When the alloy has hardened the block 13 is broken and metal, e.g. copper, is built up around the alloy casting by e.g. electrodeposition. Finally, the alloy is removed by melting away. The thickness of the separator 10 is made equal to the desired clearance between the work-loop and the gear teeth plus the thickness of metal to be built up to form the work-loop.

Filed: 1965-01-29
Abstract: 1,099,432. Feeding sheets. DE STAAT DER NEDERLANDEN, TEN DEZE VERTEGENWOORDIGD DOOR DE DIRECTEURGENERAAL DER POSTERIJEN TELEGRAFIE EN TELEFONIE. Jan. 29, 1965 [Jan. 30, 1964], No. 4073/65. Heading B6B. Documents of assorted dimensions, such as forms, cards, or letters, are separated sequentially from a stack by a friction belt 9 and fed between two rollers 1, 4, the roller 4 being driven in a direction to assist feeding the documents, and the roller 1 being driven through a slipping friction clutch in a direction to assist feeding the documents, but at a lower circumferential speed than the roller 4. Thus, the roller 1 will hold back a second document engaged thereby relative to a first document engaged by the roller 4 in the event of doublefeed, and will be speeded up to over-run the clutch when a single document is present. As shown, the bearings of the roller 1 are mounted on bar 24 pivoted at 25, and the bar is coupled to a screw-adjustable means 12-14 and spring 11, so that the roller can be adjusted relatively to the roller 4 to form a gap which is just wider than the thickness of one document. A second pair of rollers 2, 3 is arranged along the feed path, the roller 2 being urged against the roller 3 by spring means. The belt 9 passes around pulleys 6, 7 and an annulus 5a, the pulley 7 being driven intermittently by gearing (16, Fig. 2) and the gearing (16) is driven by gears (17) and pulley (19). The annulus 5a is freely mounted on a roller 5b which is toothed to receive a pair of belts 8 driven by a toothed pulley 3, and the pulley 3 is driven by gearing (18) from the shaft of pulley (19). The belt 8 also drives the roller 4 in a document feeding direction. The roller 1 (Fig. 3) has its shaft coupled by a bush (23) and a slip clutch (21, 22) to a gear (20) which is driven by known means, so that the roller 1 rotates in a document feeding direction at a lower peripheral speed than the roller 4. A single document separated from the stack by the belt 9 will pass between the rollers 1, 4, causing the roller 1 to speed up and overrun its clutch (21, 22); but when two superposed documents are separated by the belt, one will be fed forward by the roller 4, whereas the other will be retarded by the slower moving roller 1 and will be held back sufficiently to enable the first document to be fed away by the rollers 2, 3. Pile tables.-The documents are stacked on edge on a table 10 which is moved to the right, by means of a weight, to urge the stack towards the belt 9.

Title: Improvements in or relating to steam traps
IPC: F16T1/16
Filed: 1949-02-16
Abstract: 659,907. Steam traps. PORTER, W. H. Feb. 16, 1949, No. 4208. [Class 64(ii)] [Also in Group XXIX] Relates to a steam trap incorporating a release valve 23 which is opened by the pressure of condensate from an inlet 11 thereon and closed by the pressure on a piston 28 of flash steam from the condensate. According to the invention, in such a trap wherein the piston is accessible to condensate which has not previously passed the release valve, the release valve 23 co-operates with an annular seating 25 at the outlet end of a nipple 21 through which the condensate discharges, such that the cross sectional area of the release valve which constitutes the effective area on which the direct pressure of the condensate acts for opening equals the cross section of the bore of the nipple. A separate valve 31 regulates the admission of condensate to an expansion chamber 27 in which the piston, which may be provided with small through passages, fits loosely. Condensate from the inlet 11 fills an annular cavity 15 between outer and inner hollow bodies 10, 13 and a sump 37 and most of it passes, by ducts (not shown), to a top chamber 19. From thence the condensate passes to the outlet 12 by way of holes 26. The regulating needle valve 31 is screwed into a plug 30 to a distance which determines a leakage flow, through an orifice 32, of condensate from holes 36 by way of circumferential grooves 35 in the valve stem. When the condensate is hot enough it flashes into steam in the expansion chamber 27 and raises the piston 28 to close the release valve 23 on the adjustable nipple 21. Gauze filters 40 are arranged at the top and bottom of the trap. In a modification the inlet 11 communicates with the sump 37 either directly or by a downwardly-directed duct in the outer body 10. A base plug with a circumferential groove and radial holes for fluid flow replaces the base cap 16 and the cavity 15 communicates directly with the top chamber 19. The traps may be used in an inverted position. Specification 607,547 is referred to.
