Title: Improvements in means for feeding fluid material on to a moving surface
Inventor: MEREDITH JOHN
IPC: B29C48/08
Filed: 1948-06-05
Abstract: <PICT:0650898/IV (a)/1> Film-forming liquid is applied to a moving surface such as a band or belt conveyer, for continuous heat or other treatment on the surface, in a machine of the kind comprising an inclined shoot or trough whose delivery end rests on the moving surface whereby a reservoir is formed between the surface and the shoot, the machine being characterized in that the shoot is provided with a transverse baffle spaced above its floor to allow the liquid to pass in a thin wide stream thereby removing air bubbles or extraneous matter.  The surface to be coated 1 is passed over a drum 14 past a shoot 2 which is mounted upon brackets 5 forming part of a parallel motion link mechanism which is counterpoised for the weight of the shoot and which allows the position of the shoot about the drum to be varied.  The shoot is closed at both sides by end plates upon which baffle 20 is supported by vertically adjustable means to vary the clearance above the floor of the shoot.  Quadrants 15 are pivoted at 16 to the sides of the shoot and may be adjusted to close the gap between the end walls of the shoot and the drum in the various positions of the shoot, about the drum.  The shoot itself is pivotable in the brackets 5 and adjustment screws 7 are provided on an angle 6 between the brackets.  Liquid is supplied to the shoot by a pipe 19 and a well 29 having an overflow 30 is provided at the rear of the shoot to maintain a constant level.  The shoot may be subdivided allowing liquid, especially latex, of different colours to be applied to the surface.  The baffle may be straight, rearwardly bowed or angular in plan.  The shoot carries discs 32 to engage the sides of the surface 1 to prevent lateral movement of the shoot relatively to the surface.  The treated material is removed from the band at any point after treatment.

Title: Improvements in or relating to friction-clutches
IPC: F16D13/70
Filed: 1919-06-21
Abstract: 151,350. Girling, A. H. G. June 21, 1919. Clutches, friction.-In cone and plate friction clutches of the type in which the parts are operated by balls acting as wedges and pressed radially by an axially-sliding cone. the angle of the cone is such that the clutch spring will cause the balls automatically to drive the cone back or cause them to be automatically displaced by the cone, provided that the balls rotate around the cone. Figs. 1, 4, and 6 show forms in which the balls press back the cone, and Figs. 3 and 5 forms in which the cone displaces the balls. A driven clutch cone C, Fig. 1, is pressed into clutching engagement with a driving-cone A by a spring E, and the clutch is disengaged by a lever G giving axial movement to a cone F, turning with the clutch cone C, which presses balls H radially between inclined surfaces A<1>, C' on the parts A, C. The angle of the cone F is such that the radial pressure of the balls can press the cone F back only if the balls and cone are rotating relatively, so that, when the lever G is released, the balls strike out a helical path on the cone and the clutch cones approach each other more slowly as the difference in speed of the parts A, C, and thus of the parts F, H, diminishes. A groove in the cone F may be engaged by the balls F when the clutch is fully disengaged, so that an effort on the lever G is required to start the engaging action. In the form shown in Fig. 4, the non-rotating cone J is external to the balls J<1> and a spring L<2> acts on the lever L' to cause slip of the clutch cones at low speeds, the centrifugal action of the balls J<1> pressing back the cone J at high speeds so as to stop the slip. In the form shown in Fig. 6, plates P', respectively secured to and sliding relatively to a shaft P, grip a plate Q, turning with a shaft Q<1>, under the action of blade springs P<2> engaging pins P<x> in the fixed plate P'. The balls R engaging the cone R' and surfaces P<3>, Q<2> on the movable plate P' and on a sleeve Q<3> secured to the shaft Q<1> and carrying lugs Q<4> with which the inner edges of plates Q<*> carrying the plate Q loosely engage. The surface P<3> is made spherical with a centre at the centre of the plate Q, as is a thrust surface on the shaft Q' engaging balls Q' on the shaft P, so as to allow relative universal movement of the shafts P, Q'. In the form shown in Fig. 3, the clutch spring E' bears on the operating-cone C<5>, the angle of the cone being such that the cone will advance automatically to cause clutching only when the balls H' and cone C<5> are rotating relatively. As shown in Fig. 5, clutch plates M may be disengaged from the driving-casing N by light springs M<4>, the cone O<1> being secured to a lever O<2> which is pressed by a spring O<3> to clutching position in the manner described. The balls O increase the clutching effect by centrifugal action at high speeds.

Abstract: 1,208,796. Making valves. J. L. GRATZMULLER. 3 April, 1969 [10 May, 1967], No. 15924/68. Heading B3A. [Also in Division F2] A valve comprises two body parts 2, 22 (see Division F2), which are joined together by a crimped flange 24. In making the valve, a bore 34 and a lower face of the part 22 are machined without removal of the part from a machine tool, as also are an upper face of a seating 12 and a bearing face for a diaphragm 28 in the part 2. The bearings 36, 38 in a guide 20 are similarly machined with a face against which a valve carrier 40 bears. Finally the parallel faces that bear against the diaphragm 28 and a washer 42 in the carrier 40 are machined. These operations ensure that the correct gripping force on the rim of the diaphragm is obtained together with the correct alignment of the parts of the valve.
