Title: Apparatus for continuously and mechanically compacting textile and paper webs or other compactable material webs
IPC: B31F1/18
Filed: 1965-07-19
Abstract: 1,104,972. Finishing fabrics; textile treating apparatus. G. BECHER. 19, July, 1965 [18, July, 24, Feb., 1965], No. 30516/65. Headings D1L and D1S. Apparatus for continuously compacting a textile fabric or paper web h by passing the web h between a conveying roller a and a further roller c driven at a lower peripheral speed than the roller a and by means of a shoe b associated with the roller a and having a concave inner surface adapted to the shape of the roller a to form a channel g for the web h, is characterized in that a shoe d is associated with the roller c to form a channel for the web h and in that both the width of the channels and the distance between the rollers a, c is adjustable in accordance with the thickness of the web h. In one embodiment, Fig. 1, the bearings of the rollers a, c and the shoes b, d are displaceable parallel to their axes. The surfaces of the rollers a. c are roughened and the surface of the roller c may have a higher coefficient of friction than that of the roller a. The smooth-surfaced shoes b, d may be provided with parallel displaceable rails m, n, Fig. 3 (not shown.). Preferably, the rollers a, c and/or the shoes b, d are heated to prefix the compacting. The apparatus may effect creping or pleating of the web h. The roller c and the shoe d are hollow bodies with apertures i for introducing a physical or chemical treatment medium, e.g. a gaseous medium, such as steam or air, or a liquid or powdered medium, onto the web h. Non-rotatable walls j in the roller c limit the outlet of the medium to the zone of the shoe d. After compacting, the web h passes on a conveyor e to a felt calender f to fix the compacting. In a modification, Fig. 2 (not shown), a further compacting roller k with an associated shoe l is provided. The roller k has a rougher surface and is driven more slowly than the roller c. In the embodiment of Figs. 4 and 5 (both not shown), the web h is compacted laterally by rollers a, o and shoes b, p. The roller o is rotated slightly faster than the roller a and is provided with curved guide lines q, e.g. milled grooves or superimposed profiled wires.  In a modification, Fig. 6 (not shown), the lateral compacting roller o, is formed with guide lines q, which are straight in the development thereof but have different pitches. The apparatus may be constructed to first longitudinally and then laterally compact the web.

Title: Improvements in or relating to hop picking apparatus
IPC: A01D46/02
Filed: 1956-10-08
Abstract: 821,559. Picking hops. HINDS, G. A. Jan. 8, 1958 [Oct. 8, 1956], No. 30665/56. Class 6(3). An apparatus for stripping hops from detached laterals comprises at least one pair of plucking drums 11 with yieldable fingers 8, 9, rotating about parallel axes, an openwork support 15 extending between the drums, and means 16 for retaining the laterals on the support during plucking. The drums are similar to those described in Specifications 520,997 and 769,559 and have rod-like fingers 9 or loops 8. The openwork support comprises transverse rods 17 spaced 2 inches apart and interconnected by wires 18 looped around the rods and spaced at about 4 inches. The rods engage sprockets 19, 20 by which the support is continuously driven. The fingers pass through the support during stripping and the laterals are retained thereon by a set of transverselyspaced fingers 16 resting on the upper run of the support and secured at their other ends to the main frame work of the machine. As shown in Fig. 1, two overlapping supports 15 are provided, the stripped hops falling through on to a conveyer 51. The drums are driven in opposite directions by belts 30, the upper and lower drum-speeds being respectively 400 and 375 r.p.m. Below the rear end of each drumsprocket 20 is a beater 57 which beats the return run of the endless support to detach hops which may be carried over.

Title: Improvements in or relating to the preparation of catalytic agents
IPC: B01J23/70
Filed: 1932-11-01
Abstract: Metallic iron, nickel, and cobalt catalysts are produced by treating their salts with a more electropositive metal in a non-oxidizing organic liquid medium and preferably at atmospheric temperature.  For example, iron is prepared by treating an ethereal solution of hydrated ferric chloride with magnesium ribbon.  Nickel is obtained from its bromide, and cobalt from cobaltous chloride, by treating these salts in xylene with powdered zinc.  The metals are separated magnetically or otherwise from the precipitating metal and are protected against oxidation. They are suitable as hydrogenation catalysts.

Abstract: 618,028. Twisting threads. SOC. RHODIACETA. Oct. 15, 1946, No. 30713. Convention date, Nov. 30, 1945 [Class 120(ii)] In a twisting machine in which the thread is given more than two twists per revolution of the spindle by mounting a support concentrically with a "doubletwist " spindle and rotating in the opposite direction thereto, the thread passes through the air gap 32 of an electric motor, of which the rotor 24 drives the thread support 9 and of which the stator 21 is fixed to the frame of the machine, during its journey between the lower orifice 7 of the spindle 1 and a fixed thread-guide 33. Support 9 is carried by a mandrel 8 to which rotor 24 is keyed. Spindle 1 is driven, by a belt acting on pulley 20, in the opposite direction to rotor 24. The thread is guided through the air gap by a cupshaped or bladed member 19 formed of electrically non-conducting material to avoid Foucault currents. Support 9 may constitute the feed bobbin or the receiving bobbin; in the latter case a thread guide device is provided for winding the twisted thread on support 9, actuated by the rotation either of the mandrel or the spindle.

Title: Lubricated split ring closure stop-cock
IPC: F16K5/18
Filed: 1936-11-11
Abstract: 484,920. Plug cocks. SHAFFER, W. D., and SCHWEITZER, F. J. Nov. 11, 1936, No. 30819. [Class 135] To facilitate rotation under high pressure, a ported split closure ring is adapted to be engaged by an inner member integral with the actuating spindle so as to contract the ring and release it from the bore before rotating it. A casing 2 has ports 3, 4 and a bore 5 in which fits snugly a split ring 10 the split being along a line 13, and the ring has ports 11, 12. The ring is formed internally with helically inclined lugs 14, 15, Fig. 4, the lugs being on opposite sides of a line passing through the centre of port 11. The ring is rotated by a core 20, Fig. 3, having a bore 20a and spindle 22 and formed with recesses 26, 27 complementary to but wider than the lugs 14, 15 respectively. A shoulder 28 and a removable plate 31 moving with lost motion in recesses in the ring, prevent axial movement of the ring on the core. Normally the ring 10 fits the bore snugly, but upon rotation of the core, relative movement of the faces of the ring along the line 13 occurs, the ring being thereby slightly contracted and the pressure against the wall eased. Lubricant may be introduced to grooves 5a, Fig. 6, in the shell through valves 36 adapted for the attachment of a grease gun. British Specifications 15725/12, 338,913, [both in Class 135], and U.S.A. Specifications 2,027,108 and 2,039,465 are referred to.
