IPC: G01D15/14
Filed: 1931-07-09
Abstract: 384,692. Recording-apparatus. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.- (Assignees of Rusher, M. A. ; 10, Holmes Street, Scotia, New York, U.S.A.) July 9, 1931, No. 19787. Convention date, July 9, 1930. [Class 106 (iv).] A photographic recording-apparatus for use with oscillographs or other electrical measuring instruments comprises a galvanometer element provided with a mirror for reflecting a beam from a source of light, means for obtaining a record of the reflected beam, and means for intercepting the beam when it passes through the zero or other predetermined position. The invention is particularly applicable for identifying records produced on a single recording surface by a plurality of oscillographs. As shown in Fig. 1, a number of galvanometer elements 10 carry mirrors 11 which reflect a beam of light from a source 12 on to a sensitized film-strip 14 in front of which is placed a bar 15 provided with slidable holders 16. Each holder, Fig. 3, carries a metal pin 17 which is positioned to intercept the reflected beam when the element is at its position of rest. By this means a series of breaks occurs which breaks fall on horizontal lines appropriate to each record. The holders 16 may be moved to intercept the beam at determined values or be moved to inoperative positions.

Abstract: 596,754. Hair clippers. HORSTMANN, S. A., and HORSTMANN, Ltd. Aug. 2, 1945, No. 19897. [Class 131] In an electrically-driven hair clipper the lower fixed cutter is thinner at the front than at the back and the upper oscillating cutter is carried by the forward ends of a bridle-piece which extends rearwardly within the casing and at its rear end is pivoted on an adjustably mounted pin so that the longitudinal position of the upper cutter relative to the lower cutter may be adjusted to cut the hair to different lengths. As shown in Figs, 2 and 3 the lower cutter 13 is fixed to the front end of the lower casing 10 to which an upper cover is screwed and spaced apertures in the moving cutter 14 are engaged by the downturned forward ends 25a of the bridle-piece 25 which is made of wire and is pivoted on the pin 26 upstanding from a crank plate 27 which is itself pivoted on the casing 10 by a pin 28 and is adjustable by the lever 29 so that the cutter 14 may be moved forward or backward on the lower cutter 13 and by engagement with suitable abutments on the casing 10 limits the adjustment of the upper cutter. The cutter 14 is driven by the armature 15 of the electro-magnet 16, the ball-shaped end 34 of the shouldered pin 32 attached to the cranked end 15b of the armature, engaging the bridge-piece 30 which slidably engages the ends of the bridle-piece 25. The resilient pressure between the cutters 14 and 13 is adjusted by the screw 21 which passes through the bottom casing 10 and screws into the extension 15a of the armature beyond the point where the armature is mounted on the lower casing by the pivot screw 17 and the lateral position of the armature and hence the " throw " of the cutter is regulated by the springs 18, 19 adjustable by the thumb screw 20. The supply leads 51 enter at one side of the rear end of the casing through a rubber sleeve 52 clamped between the two parts of the casing and having a suspension loop at the farther end of the sleeve. A short-haired brush at the front end of the casing prevents the entry of hair clippings.

Title: Improvements in feed mechanism for printing machines
IPC: B65H3/38
Filed: 1922-07-25
Abstract: 205,871. Waite, F., and Waite & Saville, Ltd. July 25, 1922. Tripping-arrangements.-In connection with a device for feeding sheets to platen presses of the kind described in Specification 20149/04, a feeler mechanism is employed for checking the impression if a sheet is not fed to the feed table 16. While the sheet is on the table 16, it is acted on by a feeler 25 which acts to check the impression by means of a lever 50 in known manner if a sheet is not fed to tabled. This feeler is of light construction, and is caused to make its falling motion in part under spring action, and to complete it by gravity. The feeler 25 is on a shaft 26 provided with a lever 32 operated by a lever 33, link 34, lever 35, and cam 36 to raise the lever. When a roller k on lever 35 enters the depressed part of cam 36, the lever 33 moves in a clockwise direction to permit lever 32 to follow to it, and thus allow the feeler 25 to descend. It descends under the action of a spring-controlled lever 28 on an arm 27 on shaft 26 until a stop 39a meets the side of the machine frame. The arm 32 then follows the lever 33 under the action of gravity only, and while so moving the absence of a sheet is felt for, and the machine checked if the sheet is absent.

Abstract: 665,036. Filters. UNITED STATES HOFFMAN MACHINERY CORPORATION. Aug. 4, 1949 [Aug. 4, 1948]. No. 20354/49. Class 46 Dry-cleaning solvent containing suspended dirt particles is forced under pressure into contact with at least two parallel filtering elements each comprising a coarsely-foraminous metal framework covered by a layer of finely porous material to cause the solvent to flow through the layers, a relatively-high direct-current voltage being maintained on at least one of the frameworks to produce an electrical field between the elements and thereby prevent packing of dirt at the surfaces of the finely porous layers. Suspension is pumped at 91 into a cylindrical tank 10, Fig. 1, containing a number of filter leaves 34, 35, Fig. 5, mounted on a manifold 36, Fig. 3, having outlet pipes 72. 73. The top of the manifold 36 is constituted by a cover plate 68 of electrically insulating material. into which are threaded metal bushings 74 internally tapped to r,eceive the tapered lower ends 79 of metal nipples 52, Fig. 9, of the elements 34, 35. The bushings of elements 34 are connected through branch conductors 78 to a common conductor 76 connected through lead 124 to a high voltage D.C. source such as will provide a potential gradient of 6,000 volts per inch between adjacent elements. The bushings of elements 35 are connected to branch conductors 82 which are connected by screws 84, which penetrate the cover plate 68, to the manifold 36. Casing 10, and hence the manifold 36, is earthed. The elements are separated by shields 86 of a non-conductive material having reduced portions below the cover plate 68 held by a pair of rods 90. The high potential for the elements 34 is provided by a power pack 114, Fig. 10, having one terminal earthed and the other connected to the lead 124. The pack 114 is supplied from 120-volt A.C. mains through a magnetic starter box 106, a pump motor 120 being incorporated in one of the leads 118. A float-operated switch 98 (see also Fig. 1) is provided just above the filter elements in the lead 119 to cut off the current and thus prevent arcing between the filter elements if the liquid level falls below the tops of the elements. plug connections 122 are also provided for breaking the circuit when the cover 14 of the filter is removed. Each filter element comprises a marginal U-shaped frame 44, Fig. 9, which supports a relatively coarse metal screen 46 having a layer of relatively fine screen 48 on each side of it. The frame and screens are mounted in a slot 50 of the discharge nipple 52, and are encased by a fabric filtering medium in the form of an open-topped rectangular bag 58 having a neck 60 at the centre of the bottom. The neck is secured by a clip 64 and the upper edge, having a bead 66, by a U-shaped clamping member 68. Where the screens 48 are sufficiently fine the fabric filtering medium 58 may be omitted. The screens 48 may be 80-mesh electroformed screens having lands with flat surfaces confronting the body of liquid to be filtered to facilitate removal of solids collecting on the surface.
