Title: Improvements in or relating to methods and apparatus for galvanizing or zinc coating iron or steel articles
IPC: C23C2/02
Filed: 1934-01-24
Abstract: An iron or steel article, e.g. a wire or a coil of wire, is annealed in a tubular or muffle furnace or an annealing pot or pan in which is maintained a gaseous atmosphere which produces a nitrogenizing or a carbonizing or a combined nitrogenizing and carbonizing effect on the surface of the article, and is then coated with zinc by passing it through a bath of molten zinc.  The wire &c. may be passed direct from the annealing furnace into the galvanizing bath without coming into contact with the air, e.g. by passing it through a hollow conduit connecting the furnace with the bath, or, after annealing, it may be pickled and fluxed prior to galvanizing.  The desired atmosphere in the annealing apparatus may be obtained by introducing a gas or gases such as ammonia, carbon monoxide, or methane, or by introducing a salt, such as ammonium carbonate, which will decompose into or evolve a gas or gases possessing the desired properties.  The temperature in the annealing apparatus is preferably maintained between 680 and 780 DEG  C.  Specifications 226,150, [Class 82 (ii)], and 345,598 are referred to.

Title: Improvements in or relating to a method of producing dimensionally stable plastic tubular members and apparatus therefor
IPC: B29C48/09
Filed: 1963-01-22
Abstract: 1,023,122. Moulding hollow articles. REMINGTON ARMS CO. Inc. Jan. 22, 1963 [Feb. 6, 1962], No. 2789/63. Heading B5A. Apparatus for producing plastics tubing, e.g. shortshell casings, from pre-formed slugs preferably of high density polyethylene, comprises a die structure having an elongated passage of annular cross-section, the portion of said passage adjacent the discharge end of said die having a gradually increasing mean diameter and a gradually decreasing cross-sectional area and a hollow reciprocating ram which pushes the preformed slugs successively through the die structure. The die structure, Fig. 3, comprises a cylinder 18, 19 within which is located a female die member 22 having an external helical groove through which a heating liquid, e.g. water, between 150-210 F., is circulated. Within the die member is a two-diameter mandrel 27, 27a, the part 27a of which has a conical end 27c to facilitate entry of the slug. At the discharge end of the die structure the mandrel enlarges and the adjacent surface of the die member 22 widens to narrow the annular through passage. The mandrel co-operates with a reciprocable hollow ram actuated by a piston and cylinder motor 34, 35. The grooves 27b in the mandrel and a hole 31b in the ram allow drainage of excess lubricant carried by the slugs. The stroke of the ram is such that it requires two reciprocations to force a slug through the die structure. The slugs are fed in series to the loading station through a serpentine shaped channel which passes through a tank containing a heating liquid lubricant. A ring 28 adjacent the exit of the die structure gives the tube a ribbed or corrugated surface. The mandrel has a recess 27f which is engaged before actuation of the ram by the end of a retaining rod 38, Fig. 2, connected to the piston-rod of a pneumatic motor 39. The retaining rod 38 is locked and held against the force of the ram by a locking device including two rollers 49a, 51a actuated by a pneumatic motor through a linkage to engage a spool member 41 on the rod 38. A fixed bush 43a strips the elongated tubes from the retaining rod 38 as the latter is retracted so that the tubing drops on to a conveyer comprising two belts movable over rigid frame plate member in opposite directions, the lower belt moving away from the die structure at a higher speed than the upper belt moves towards the die structure. The space between the belt is such that the tubes are squeezed and rolled. Cooling blasts of air are directed on to the tubings in the conveyer which may comprise one belt and a stationary plate. A second similar die structure may be located on the other side of the ramactuating motor.

Filed: 1956-01-30
Abstract: 805,106. Laminates. UNITED STATES RUBBER CO. Jan. 30, 1956 [March 21, 1955], No. 2890/56. Class 140. [Also in Group XVII] Flexible rubber containers are made by bonding a layer of thermoplastic resin to a layer of an adhesive vulcanizable rubber to form a flat laminate, heating two of such laminates to a deformable state, drawing them into two arcuate segments with the rubber surface facing outwardly, placing the two segments in mating, face-to-face relationship so that the resins coalesce at the juncture into a continuous wall and maintaining the segments in drawn shape while cooling them to a temperature at which the thermoplastic layers retain their shape. This assembly may then be inflated with fluid such as air, have pieces of vulcanizable rubberized fabric placed on it and be disposed in a mould having the shape of desired container and the whole vulcanized. Butyl or reclaimed butyl rubber compounded for vulcanization may be used and as thermoplastic resin polyethylene may be used. The lamination may be by a heated press, pinch rolls or a calender or butyl rubber may be formed into a sheet and polyethylene deposited thereon as a surface layer by calendering, or skim coating or polyethylene may be formed into a sheet and butyl rubber calendered thereon. Polyethylene may be sprinkled or dusted on to a butyl rubber layer before lamination with a polyethylene layer. Better bonding of virgin butyl rubber is obtained by either an under-cure or an over-cure. The laminate 10 (Fig. 1) is vulcanized in press 13 and cut or stamped to an oval shape. A metal ring 15 is placed on the thermoplastic surface and the assembly heated. Two such assemblies, with the edges wrapped over the metal ring, are placed on the hinged mould assembly 21 and air is withdrawn through ducts to cause the assemblies to form arcuate shapes, the mould is then closed, bringing the two shapes together, and allowed to cool. The outstanding rim including the metal ring is cut from the container. An outlet is generally left leading from this inner assembly, through which it may be inflated and shaped pieces of corded fabric skim-coated with butyl rubber placed upon it. A pipe-nipple is attached to the outlet and the whole is then placed in a hinged mould, Fig. 8, and vulcanized. A screwed outlet pipe may be fitted into the crude outlet.

Title: Improvements in radiation pyrometer with illuminator
IPC: G01J5/52
Filed: 1951-02-06
Abstract: 721,148. Automatic temperature control systems. LEEDS & NORTHRUP CO. Feb. 6, 1951 [Feb. 7, 1950], No. 2925/51. Class 38 (4). [Also in Group XL (b)] In a system for measuring or measuring and controlling the temperature of a surface 10, Fig. 1, of heated material 11 an illuminator surface 16 is placed adjacent surface 10 to define a measuring zone therebetween, the illuminator being provided with heaters and having a peripheral area 40a for inwardly directing energy received by the peripheral area, and a pyrometer 25 is positioned to receive energy from the zone. Black body conditions are simulated in the measuring zone by the addition to the radiant energy emitted directly from the restricted portion of surface 10 so as to enter pyrometer 25, of reflected energy emitted from other parts of surface 10 opposite the illuminator, and from the illuminator surface 16. To prevent radiant energy within the zone from escaping and external energy from entering, the peripheral portion 40a of the illuminator is formed with saw-tooth cuts whose surfaces lie at angles of 60 and 30 degrees respectively to the flat central portion of the illuminator and skirts 45 are provided. A heater-controller 18 receiving the output of a thermometer such as a resistance thermometer or thermocouple 20 in contact with illuminator 16, maintains the latter at the desired temperature of surface 10 by means of electrical heater 17. Any temperature variation of surface 10 changes the radiation received by the sensitive element 24 of the total radiation pyrometer 25 and the resultant rotation of the slidewire 26 by means of the mechanical relay MR, controlled by galvanometer G, in order to rebalance the potentiometer measuring circuit which includes battery B, and resistor 33, causes both a pen and indicator 29 to move relatively to a record chart 30 and scale 31 and also to make the temperature controller 32 change the setting of the valve 15 or the like to increase or decrease the heat applied by chamber 14 to the moving material 11. The valve 15 may be cyclically operated between " on " and " off " positions or may be adjusted to an intermediate position. The illuminator 16 which may be of polished chromium plated iron or copper, polished stainless steel or aluminium, is heated by the strip heaters such as 46, 48, 49, Fig. 8, which are clamped thereto, and covered by glass wool 60, held in place by cap 63. The pyrometer 25 is secured to illuminator 16 at an angle of 60 degrees thereto and may have its lower end cooled by a water jacket. The skirts 45 of Fig. 1, may be formed of blocks 64, surrounding the edges of the illuminator so as to serve also as bumpers, the assembly being mounted by brackets 58. In a modification the peripheral area 40a is roughened or sand-blasted or may comprise oxidized copper, platinum black or shellac. Specification 721,147, [Group XL (b)], is referred to.

Abstract: 933,525. Gating circuits. SIEMENS & HALSKE A.G. Jan. 25, 1962 [Jan. 26, 1961], No. 2950/62. Class 40 (6). [Also in Group XIX] A logic circuit comprises a number of input windings and at least one output winding on a magnetic core, it being arranged that the core is operated over the linear portion of its magnetization curve. Several embodiments are described. In a typical embodiment, Fig. 2, the core M has mounted on it windings I, III and IV (having one sense) and winding II (having opposite sense), the sense of the windings being indicated by the slope of the lines. Binary signals Ex, Ey bias diodes Gx, Gy, and a positive pulse at E is fed via like valued resistors R1, R2, R3 to windings I, II and III. If a binary signal has the value 1 the winding to which it is applied is blocked. Thus, in the present example, no pulse will appear on terminal A if Ex=1 and Ey=0 but a pulse will appear for binary signals 00, 01, or 11. In all further embodiments each binary signal input circuit comprises a resistor R and capacitor C, but these are not shown in the Figures. Fig. 3 shows a sheffer's stroke circuit which pulses for signals 00, 01, 10, but not 11. If a diode Ga is placed in the output line, for example as in Fig. 9, it is not necessary for the number of turns on the input windings to be precisely equal or for the resistors R1, R3 to be carefully matched. Figs. 10-16 (not shown) illustrate circuits wherein each input diode G is preceded by an AND gate or an OR gate. Fig. 17 (not shown) gives a circuit which does not pulse unless m out of n input signals are "0." In Fig. 19 the logic circuit (an exclusive OR gate) is followed by an inverter; and in Fig. 20 a transistor in the output line feeds back a current to a winding U, thereby to cause the transistor to trigger quickly and produce a steep-fronted output pulse. Specification 906,158 is referred to.

Abstract: 305,214. Soc. Rateau. Feb. 2, 1928, [Convention date]. Void [Published. under Sect. 91 of the Acts]. Regulating or controlling; casings.-A centrifugal fan or pump is controlled by the introduction of a ring member into the diffuser, the member being displaced in a direction parallel to the axis. In the form shown in Fig. 1, the rotor a delivers fluid to the volute b through the diffuser c. A vane ring d can be inserted into, or withdrawn from the diffuser according to the conditions of pressure and output required. Pipes h, f connected to the volute and rotor chamber respectively, may be connected by a cock i to a tube g. With the tubes h, g in connection, as shown, the vane ring d is moved to position in the diffuser, whilst when the tubes f, g are in connection the ring d is moved out of the diffuser which is then vaneless. The ring may be mounted on helicoidal slides to promote even movement. Two vaned rings may be employed, a ring being mounted on each side of the machine, the vanes of the rings being adapted for different running conditions. In a modification, two combined rings d<1>, d<2>, Fig. 5, with vanes of different pitch, can be brought into position in the diffuser by means of a number of screws j. In another modification the ring d, Fig. 6, is left in the diffuser and the delivery is modified by moving the cheek k by means of the screw j to vary the effective width of the vanes. In another modification the vane block d, Fig. 7, can be retracted from the diffuser, and the cheek k can be moved to vary the distance between the diffuser walls. The arrangement may be applied to multi-stage machines.
