Title: Improvements in and relating to vulcanising presses for band-shaped articles such asconveyor belts
IPC: B29C35/00
Filed: 1961-04-24
Abstract: 916,808. Stripping vulcanised articles from press plates. SIEMPELKAMP, E. April 24, 1961 [April 26, 1960], No. 14693/61. Class 87(2). A vulcanising press for band-shaped articles e.g. conveyer or drive belts, comprises a press frame 2 having upper and lower heating plates 3, 4 respectively arranged therein, a clamping and stretching device 6 for the bandshaped article 1 and a separating traverse, e.g. a roller 7, associated with at least the bottom heating plate which is wider than the article 1 and is movable by the aid of driven pull members 9 between the heating plate and the article 1 to separate them. The upper heating plate 3 is vertically reciprocable to compress part of the band-shaped article 1 between it and the lower heating plate 4. A roller 7 (not shown) is associated with the upper heating plate 3, hydraulic cylinders being provided for vertical reciprocation, of the roller 7 with the plate 3, by reciprocation of pulleys 8 round which the driven pull members 9 pass. The separating roller 7 associated with the lower heating plate 4 is shown in Fig. 4. The roller has outer stepped portions 7a which rest on tracks 10 and keep the roller 7 clear of the surface of the plate 4. After the upper plate 3 has been raised the roller 7 is moved from its rest position round a curved portion 10a of the tracks 10 and along the tracks 10, by movement, of the driven pull member 9, to separate the article 1 from the plate 4. The roller 7 is connected to further rollers 11a, 11b, 11c to form a chain by intermediate pull members 12, and these rollers distribute themselves along the length of the plate 4 and prevent the article 1 from sagging into contact with the plate 4. As the next length of the article to be vulcanised is drawn into the press by removal of the vulcanised length, e.g. by driven knurled rollers as a coiling device (not shown), the rollers 7, 11a, 11b, 11c are moved back to.their rest position at the left of Fig. 4, the clamping and stretching device 6 is operated and the upper plate 3 is lowered. As the roller 7 passes over the plate 4 it also forces side constraining bars 5, Fig. 2, on to the plate 4 during the separation of the bandshapedarticle 1. The press frame may be recessed on both sides to render the heating plates and the rollers accessible, and the rollers 7, 11 may be conducted in a complete circuit instead of being reciprocated over the surface of the plates.

Title: Improvements in non-inductive electric resistors
IPC: H05G1/08
Filed: 1943-09-08
Abstract: 566,559. Wire resistances. BRITISH THOMSON-HOUSTON CO., Ltd., and COX, H. E. Sept. 8, 1943, No. 14698. [Class 37] A non-inductive resistor comprises a plurality of coils located in spaced circumferential grooves in an insulating former, the coils being in the form of flat spirals and wound from a continuous length of wire in the same direction, the portions of the continuous length of wire forming the connections between adjacent coils being so disposed that, when current flows in the resistor, its direc. tion in adjacent coils is opposed. The resistance is wound on a former made by threading insulating discs 4, 5, 6 or a square insulating rod 3- The flat spiral coils 7 lie between discs 4 and 6, the inner diameter of the coils being determined by the diameter of the small discs 5 whose thickness is the same as the diameter of the wire. The resistance is wound from a single length of wire on a spool, by the following method. The first coil is wound on, the outer free end being connected to terminal 14<1> and the inner end, still connected to the spool, is carried through a radial slot 8 in the next disc 6 and engaged in a notch 9. Sufficient wire for the next two coils is unwound from the spool and held out in a bight, the end next the spool being engaged in the notch 9 of the next disc 6. The former is then rotated to wind the two coils together until the bight is absorbed, the end of the bight finally straddling a peripheral notch in the disc 4 between the two coils. The rest of the coils are similarly wound in pairs and the last free end is connected to terminal 151. The upper end of spindle 3 has a metal member 12 carrying a nut 18 which serves to adjust a spring 16 which holds the coils in compression. The ends of the resistance are electrically connected to metal end plates 20, 21 sealed to an insulating tubular casing 19 which may be filled with oil.

Abstract: 1,041,387. Air conditioning. BUENSODSTACEY CORPORATION. April 11, 1963 [May 3, 1962], No. 14712/63. Heading F4V. In an induction type air conditioning system the temperature of the zone to be conditioned is controlled only by varying the temperature of the primary air supply. Ducts 16 and 17 of a dual duct system are supplied with warm and cold air from a central conditioning unit and feed a mixing chamber 15 located in, or under the floor near, a distribution unit 10, one distribution unit being provided for each room or zone to be conditioned. A valve 18 controlled by a pneumatic or electric zone thermostat 19 proportions the mixture of warm and cold air supplied via a constant volume flow rate regulator 20 to a duct 14 of the unit 10. Air from the duct 14 passes to a header 11 and is ejected from the unit through nozzles 12 and a grille 13. A flow of recirculated room air is thus induced through a grille 21 and over a heat exchanger 22 which is fed with fluid from a closed system including a pump 25 and reservoir 26. The reservoir 26 is heated or cooled according to the season and the heat-exchange fluid circulates at a constant volume flow rate. In a modification, Figs. 2 and 3 (not shown), two heat-exchangers are disposed in the path of recirculated air above the primary air header which may be provided with a slit in place of the nozzles, and a pivoted flap proportions the warm and cold air.

Title: Improvements in or relating to machines for feeding metal strip material
IPC: B21D43/09
Filed: 1953-05-27
Abstract: 731,883. Variable-speed gear. LITTELL MACHINE CO., F. J. May 27, 1953 [Jan. 29, 1953], No. 14748/53. Class 80 (2). [Also in Groups XVI and XXII] Apparatus for feeding metal strip having feed rolls and power driving means therefor has included in the driving connection between the feed rolls and the power means a variable-speed pulley unit mounted for bodily movement in the directions of the belt driving connections therefrom to effect a change in the speed of the feed rolls, manually operated means being provided for adjusting the position of the pulley unit and other means for automatically varying the position of the pulley unit within limits with respect to any position selected by the manual means. Strip passes to intergeared opposed feed rolls 37, 38, the upper roll 37 being liftable for the insertion of the strip, from straightening rolls 31 and 32, the latter 32 being driven from the feed rolls, and continuously from the feed rolls, in a loop, to blanking, punching or other metal-working apparatus. To maintain the size of the loop substantially constant, a variable-speed pulley unit 72 is provided in the drive between an electric motor 70 and a speed-reducing gear unit 55 driving the feed rolls through an endless chain 61. The pulley unit 72 comprises an outer pulley disc 76 and an inner pulley disc 77 mounted on a trunnion rotatable on a shaft 73 and a central double cone pulley disc 78 rotatable and slidably mounted on the trunnion. An endless belt 80 drives the discs 76, 78 and an endless belt 81 is driven by the discs 77, 78, vertical movement of the pulley unit shifting the disc 78 laterally and, as one belt moves further in towards the trunnion and the other further out, varies the speed ratio between the belts. The pulley unit 72 is carried on one arm 74 of a bellcrank lever pivoted at 93, the other arm 82 having pivoted thereto a block 87 secured to a pivot pin 91 in turn connected to a rod 98. A screw 84 rotated by a handle 83 and threaded into a clevis 85 connected to the block 87 rocks the bell-crank lever, the rod 98 preventing the block 87 from turning relatively to the bellcrank lever, to give the manual vertical adjustment of the pulley unit 72. The pulley unit 72 is also automatically adjusted, to vary the speed of the feed rolls up to approximately ten per cent of the manually adjusted speed, under control of a pivoted arm 62 resting on the metal strip loop. A cam 67 (not shown) on the pivot shaft to which the arm 62 is fixed rocks a lever 95 to raise or lower the rod 98 thus to turn the pin 91 and rock the block 87, held at one end by the clevis 85, to oscillate the bell-crank lever. A cam 66 (not shown) on the pivot shaft of the arm 62 switches the motor 70 off, if the arm 62 drops too low.

Title: Method and apparatus for making or forming helically finned tubing
IPC: B21C37/26
Filed: 1958-05-09
Abstract: 846,803. Coiling.strip on tubes. MATHENY, W. F., and MATHENY, W. F. Jun. May 9, 1958, No. 14913/58. Class 83 (4). A method of making helically finned tubing by spirally winding a strip of metal on to a continuously rotating and advancing tube comprises longitudinally feeding the strip towards the tube with the strip disposed edgewise to the surface of the tube with one edge thereof in a line intersecting the periphery of the tube to radially deform one edge of the strip on the surface of the tube into tight-fitting embrace about the periphery of the tube whilst stretching the opposite edge of the strip to form a helical fin. A tube 28 is rotated and fed longitudinally, by means 29 (not shown) through a hollow shaft 17 rotated by a pulley 20. Strip 45 from a reel (not shown) passes between rolls 50, 51, Fig. 3, which form a flange 63 along one edge of the strip, the roll shafts being journalled in an adjustable bracket 57. The thus-flanged strip then passes over an arcuate guide 64, Fig. 8, having side guide flanges 66. The guide 64 is rotatably adjustable about two mutually perpendicular axes and bodily adjustable relatively to the tube 28. A nose part 67 of the guide 64 leads the strip 45 between a conical-nosed forming roll 22, secured to and coaxial with the rotating hollow shaft 17, and a dished wheel 24 on an adjustable shaft 32. The roll 22 and wheel 24 co-operate to thin the outer, non- flanged edge of the strip 45 to coil it helically, tightly, around the rotating and advancing tube 28. The strip flange 63, now engaging the tube, is pressed more firmly against the tube by a pair of parallel discs 86 urged upwardly by a spring 102 and latch means.

Title: Fish washing and transporting apparatus
IPC: A22C25/04
Filed: 1951-06-23
Abstract: 683,874. Washing fish. WOOD, W. H. Aug. 29, 1951 [June 23, 1951; July 16, 1951], Nos. 14962/51 and 16816/51. Class 28 (ii). Fish are washed in an open top tank by water from two or more swirling nozzles 18, 19, and float out at one or more (end) walls 4, 5 of lower height down a conveyer 25. The device may be used on board a trawler for delivering the handgutted and now washed fish into the hold. The bottom 1 of the tank is inclined up at 6 and 7, the upper edges being curved at 6' &c. to facilitate the overflow of the fish. The side walls 2, 3 and their converging ends 2<SP>1</SP>, 3<SP>1</SP> have inwardly directed top flanges 9 with downturned edges to prevent damage to the fish thrown by hand against them. Such flanges 9 taper away at the ends. An extra height auxiliary wall 30 may be provided on one side particularly for a washer on a ship to intercept fish when thrown in after hand gutting. When using the whole tank to wash and deliver the fish from one end only to the conveyer shoot 25, an end closure plate 12 is inserted at the other end and the tank is inclined to slope down towards the conveyer end. Such inclination can be reversed to deliver the fish into another hold in the ship, the apparatus being located between the holds. The tank may be divided into two by inserting a central division plate, so that different types or qualities of fish can be thrown into the half tank, each half doing its own washing by the swirling nozzles and delivery at each end, the tank then being set horizontal.

Title: Improvements in and connected with Gas Producers.
Inventor: SMITH DAVID JOSEPH
IPC: C10J3/00
Filed: 1917-10-18
Abstract: 120,599. Smith, D. J. Oct. 18, 1917. Fire-bars and grates; ash-pits.-A gas-producer, more especially adapted for supplying internalcombustion engines fitted on vehicles or boats, is constructed so that there is a mechanical and positive control of the fuel feed and removal, rocking of the grate, and water feed to the steam generator and to the wet scrubber if such is used ; also the producer is constructed of such a shape that the fire bed is relatively shallow in proportion to its area so that the fuel, which is fed in small but regular quantities, rapidly becomes incandescent, and is not subject to slow distillation. The mechanical control referred to is preferably obtained by gearing from a shaft geared to the engine, and in addition to this the throttle of the engine may also auto matically adjust the fuel-feed and ash-discharge and the supply of steam to the fuel bed. The producer shell may also be formed with inwardly projecting fins for keeping the fire bed well agitated. The producer comprises a circular grate formed, as shown, of six parallel sections 9 pivoted at one end 10, and resting on cams 8 on a shaft 7 driven by worm gearing from a shaft 4 which is mechanically driven, preferably from the engine shaft. The various sections 9 rise and fall in sequence, and in conjunction with fins on the shell 1 serve to agitate the fuel thoroughly. At the commencement a fire is started on the grate 9 by opening a door 13<a>, and a hand-pump 28 operates to send a blast of air through a pipe 14<b> to the space above the ash pan 16. When a gas-burner 20 indicates that the producer is working correctly the engine is started, and the shaft 4 is rotated, and thus is started (1) a pump 5 which circulates water to the gas scrubber 3; (2) a force pump 12<b>, which acts to deliver water through a tubular gascooler 2 to a steam generator 14 which delivers steam through the pipe 14<b> to the grate; (3) adjustable crank-mechanism 15, 15<a>, which operates, by means of adjustable ratchet mechanism, (a) an intermittently rotating conveyer 17, which feeds the fuel, and (b) an apertured ashdischarger 18 which intermittently discharges ashes; and (4) the rocking motion of the grate also commences.

When a master controller MS is returned from a " forward " operating position to an " off " position, the armature a of a motor M and its shunt field winding f are disconnected from supply-lines L1, L2. Closure of contacts DB2 connects a dynamic braking resistor 9 across armature a, whilst the field winding is connected across the armature through rectifier RB1, contact DB4, and rectifier RB2. The field winding is thus subjected to the countervoltage of the motor during dynamic braking operation. Return of the controller from a " reverse " position to the " off " position again connects resistor 9 across the armature, the field winding now being energized through rectifiers RB3, RB4. In a modification, the shunt field winding is normally connected across lines L1, L2, when the master controller is in the " off," " forward," or " reverse " positions, and it is connected to receive dynamic braking energization from the armature counter-voltage only in the event of complete or partial failure of the supply-voltage, Fig. 2 (not shown).
