Title: Improvements in or relating to the Manufacture of Metal Rolls.
Inventor: HADFIELD ROBERT ABBOTT
IPC: C21D9/38
Filed: 1916-07-10
Abstract: 125,422. Hadfield, Sir R. A. July 10, 1916. Rollers or cylinders.-Rolls for rolling metal &c. are made from nickel or chromium steel or both and are hardened, tempered, and toughened by alternate heating and cooling to definite temperatures. The steel may contain 0.6 per cent of carbon, 2 to 3¢ per cent of nickel, and 2 to 3 per cent of chromium, or instead of both nickel and chromium 4 to 5 per cent of either. The roll is annealed by heating to 700 to 800‹, say 765‹ C. and cooling slowly. After machining to finished shape, the roll is heated to 875 to 880‹ C., preferably while rotating with its axis vertical in a gas-heated furnace, and quenched in oil. This gives a hardness of 93 to 98 by scleroscope. The journals are protected from excessive heating by pots. The roll may be tempered by heating to 300‹ C. and cooling in air or in oil. The roll, whether tempered or not, is then heated slowly in oil preferably to 100 to 200‹ C. and allowed to cool in air. If the roll is cast instead of forged, it may be annealed at 1200 to 1300‹ C. The roll may comprise an outer tubular portion of nickel or chromium steel secured on a core of poorer quality.

Abstract: <PICT:0832963/III/1> A glass tube 16 is coated internally and/or externally with a treating, lubricating, dispersing, protecting, adhering or coating material prior to flattening, fragmentizing and incorporating in a transparent synthetic resin (see Group XXIII), or glass flakes are coated with the above materials.  The coating material may be the resin, e.g. a polystyrene, polyethylene, polyamide, polyvinyl or polyester.  Molten glass in a tank 10 is drawn through an annular orifice 14.  Tubes 12, 13, which may be concentric, either or both of which may have spray heads 15, supply a gas or vapour to the interior of the tube 16 to maintain its shape and also a coating material, e.g. in vapour form if suitable, e.g. vinyl trichloro silane, a styrene monomer or diallyl phthalate, or in liquid form, the liquid returning by the other pipe.  A liquid may be supplied through one of the pipes 12, 13 and a fluid reactive therewith through the other, and where concentric pipes are employed, air may pass through the outer pipe to cool liquid or vapour in the inner.  Coating materials in powdered form may be introduced into the tube 16.  The exterior of the tube 16 may be coated by the sprays 20 . . . 22 and roll applicators 23 may supply coating material from a heated pan 24 to the ribbon 19.  Both the interior and exterior of the tube 16 may have more than one different coating, and opposite surfaces may have different coatings.  The coating material may be applied to the exterior of the tube 16 or of the ribbon 19 in gaseous form by enclosing the parts 16, 19 in a casing.  In a modification, the ribbon 19 is split into two films each of which is spray-coated and heated to set or cure the coating material, and in another modification, the ribbon 19 is led into a bath of coating material in which the ribbon is broken by a chain conveyer which carries the coated fragments out of the bath.  The temperature of the bath is maintained by a jacket and fresh material is fed to the bath which forms part of a liquid circuit including a pump.  One of the coatings on the flakes may be metallic (see Group II).  A list of organic coating materials for improving the glass flake-resin bond, which are introduced by the tubes 12, 13 and/or by the sprays 20 . . . 22 is included in the Specification. Specifications 805,703 and 832,964 are referred to.
Patent GB-371575-A (GB)
Title: Improvements in or relating to thermionic oscillation generators
IPC: H03B5/10
Filed: 1931-04-01
Abstract: 371,575. Valve generating circuits. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE, 12, Hallesches Ufer, Berlin. April 1, 1931, No. 9906. Convention date, April 3, 1930. [Class 40 (v).] The frequency of a thermionic oscillator is stabilized by feeding back from the anode circuit a voltage which is the difference between two voltages whose phase dependence on frequency is different, whereby the phase dependence on frequency of the feed-back voltage is greater than that of each of the original voltages. In Fig. 2 the feed-back voltage is taken from the common point 5 of a tuned circuit 2 and resistance 3. At a certain setting of 2 and corresponding compensating adjustment of resistance 3, the alternating voltage between the points 6 and 5 is zero. To obtain back-coupling one of the elements 2, 3 is slightly altered which provides a feedback voltage the phase of which is closely dependent on frequency. Instead of the feedback being taken directly from the common point of the two circuits 10, 11, a differential transformer circuit 13 may be inserted, as in Fig. 3, and coupled to the grid circuit 12. In a modification of this arrangement, Fig. 4, a limiter valve 26 :is inserted between the grid and the coupling circuit 22 to eliminate frequency variation due to variation in amplitude of feed-back voltage. In all cases direct back-coupling through the oscillator valve is prevented by neutralizing or employing a screen-grid valve.

Abstract: 473,001. Gas heating-stoves. MAIN, Ltd., R. & A., and WORTLEY, G. W. April 3, 1936, No. 9952. [Class 126] [Also in Group XIII] In a gas-heated radiator in which a casing 11 has its front wall constituted by a metal radiating panel 35 and its rear wall covered by an air jacket 40 open to the atmosphere at its lower end and communicating with the space 45 beneath a cover plate 42, the tendency for air and gas currents to pass upwardly over the wall of the room above the heater is prevented by disposing the waste-gas outlets 36 in the upper part of the panel 35, the combustion gases being thus discharged beneath and separately from the hot air from the space 45. The upper part of the rear wall of the casing 11 is curved forwardly at 38 and has secured thereto a corrugated reflector 39. The casing 11 is secured, by means of a cast frame 28 and bolts 32 to a lower casing 10 fitted with a burner 22, there being arranged above the burner an annular upwardly-flared baffle 29 which has feet 30 resting on the frame 28 and is formed with end flanges through which extend the bolts 32. A curved reflector 27 is provided at the base of the burner 22 to reflect the flame upwardly through a glazed door 25 hinged at 24 to the front of the casing 10.

Title: Cutter drum
Inventor: JOHN GUENTER
IPC: A01F29/06
Filed: 1984-07-10
Abstract: A chopper has a housing centered on an axis and having a radially open input and a radially open output spaced angularly therefrom as well as a pair of axially oppositely open intakes, and a cutter drum rotatable in the housing about the axis and having a pair of end plates transverse of the axis and having axially oppositely directed faces confronting the respective intakes and a plurality of blades secured to and between the end plates and having cutting edges defining on rotation of the drum an orbit centered on the axis. Respective pluralities of vanes at the end plates can be secured either to the respective end plates in in-service positions extending generally radially thereon so that rotation of the drum moves the vanes to draw air in the axial intakes and expel it through the radial output or in an out-of-service position in which they do not move appreciable air. The vanes can be secured in the out-of-service position also to the respective end plates but extending generally only angularly. In particular the vanes form a radially closed cylindrical annulus in the out-of-service position. This annulus generally blocks flow from the intake to the output in the out-of-service position. The vanes can also be secured in the out-of service position so as not to rotate with the drum.

Title: Automatic knob fitting device
Inventor: KANAI MICHIHIRO
IPC: G05G1/00
Filed: 1982-01-08
Abstract: PURPOSE:To realize automatic fitting efficiently through a simple device by guiding a knob to positions which face each other concentrically about a rotating shaft, and pressing the knob axially and elastically and also rotating it over a slide. CONSTITUTION:The knob 1 is stored in a storage 8 by being guided from a feeder which is not shown in a figure so that the semicircularly sectioned hole 1a of the knob 1 faces the semicircularly sectioned shafts 14a of, for example, constant resistors 14 arrayed on a printed board 13 (at right angles to figure surface). A bearing block 24 for holding a spindle 23 moves forth and back through a nut 20 by being driven by a motor 16. When the tip pin 22 of the spindle 23 enters the hole of the knob 1 and further moves forth, a rubber ring 30 comes into sliding contact with the knob 1. At the same time, a rack 28 reciprocates at right angles to the paper surface to allow the spindle 23 to have one turn and half. When the semicylindrical shapes of the shaft 14a and hole 1a coincide with each other, the knob 1 engages the shaft 14a. Thus, plural knobs are fitted automatically and efficiently.
