Title: Improvements in or relating to duplicating or printing machines
IPC: B65H29/48
Filed: 1951-01-18
Abstract: 724,082. Sheet-delivery apparatus for duplicating-machines. FORD, R. M. April 18, 1952 [Jan. 18, 1951], No. 1369/51. Class 100(1). In a duplicating machine of the kind in which means are provided for feeding copy sheets to a rotary printing couple at positions spaced apart across the width of this couple, a receiving table 14 extending the full width of the printing couple is operatively disposed in the delivery path of the copy sheets and a collecting tray 18 of fractional width is movably mounted across the width of the printing couple to register with that zone of the printing couple through which each copy sheet is passed, means being provided for transferring the copy sheets in succession from the table 14 to the tray 18. The invention is illustrated applied to a duplicating-machine, as described in Specification 724,081, which comprises a main printing cylinder 16 and a secondary printing cylinder 21 movably mounted parallel to the axis of the cylinder 16 with a carriage 20. Impression cylinders 24, 25 co-operating with the cylinders 21, 16, and a feed tray 36 are also mounted on the carriage. The collecting tray 18 is mounted for movement in unison with the carriage 20 by means of rollers 27 running on rails 30. The movements of the carriage 20 and the tray 18 are controlled through interconnected cables by a mechanism described in Specification 724,081. The receiving table 14 consists of a number of wire loop members pivotally mounted on a shaft 17 extending the full width of the printing couple 16, 25 and oscillating between receiving and transferring position (shown in chain and full lines respectively). The table is spring- loaded to the receiving position and moved to the transferring position at a predetermined time in each printing cycle by a cam 31 on the shaft of the cylinder 16. Cam 31 displaces a lever 32, a pin 35 on which bears on a lever 37 and rocks it against an arm 39 on the table. A number of fingers 23 projecting through the wire loops of the table are arranged to be turned in an anti-clockwise direction to engage the edges of the sheets and transfer them to the tray 18. The fingers 23 are rotated against the action of spring 44 by the end of lever 32 bearing on a rocker 43 adapted to engage an extension 48 from the bar 19 carrying the fingers. Sheets fed from the couple 16, 25 at any point of its axial length are received on some part of the table 14 and transferred by the fingers 23 to the collecting tray which always remains vertically below the feed tray 36 and therefore collects the sheets in the order in which they passed through the printing couples.

Abstract: 644,642. Liquid-fuel stoves; liquid-fuel burners. BAILEY, W. A. Jan. 19, 1948, No. 1615. Convention date, Oct. 12, 1946. [Classes 75(i) and 126] A stove utilizing fuel rendered liquid in the apparatus in the course of its operation includes a casing containing a fuel receptacle the lower end of which is surrounded by a burner having valve controlled passageways between it and the fuel receptacle. The cylindrical fuel receptacle 16 having a hinged lid 16b and side fins 16a is disposed centrally within the casing 42, and its lower end is surrounded by an annular wick 41 contained in a U-section annular wick-holder 13.

Abstract: 1,121,632. Change-speed gear. DAVID BROWN GEAR INDUSTRIES Ltd. 6 Jan., 1967 [14 Jan., 1966], No. 1852/66. Heading F2D. A change-speed gear having high and low speed ranges comprises coaxial input and output shafts 11, 12, a parallel layshaft 13, a gear 14 fast on the input shaft and constantly meshing a gear 15 free on and clutchable to the layshaft, a gear 17 fast on the layshaft and constantly meshing a gear 16 rotationally free coaxially of the input output shafts and clutchable to either or both of said shafts, and gears 18-21 fast on the layshaft and constantly meshing gears 118-121 free on and clutchable to the output shaft. The gear 16 may berotatably mounted on the end of the input or, as shown, the output shaft. The pitch circle diameter of either one of the gears 14, 16 exceeds that of the other. Positive clutch sleeves 30, 31, respectively for clutching the gears 16, 17 to the input shaft and the layshaft, are axially slidable by forks (32), (33) interconnected by a lever (34) to ensure the engagement of only one of these clutches at a time, the forks being operated by a piston (37) actuated pneumatically or hydraulically under the control of a valve which is Bowden-cable operated by a gear-shift levermounted push-pull button. A reverse idler shaft (22) has free thereon and clutchable thereto a gear (23) constantly meshing a gear 24 fast on the layshaft, and a gear (25) fast thereon meshing a gear 26 splined on the output shaft and integral with a positive clutch sleeve 42. Positive clutch sleeves 40, 41 and the sleeve 42, respectively for clutching the gears 16, 118 and 119, 120 and 21, to the output shaft are axially slidable, from neutral positions, by forks 140- 142 fast on shift rods 43-45. A clutch sleeve (49) for clutching the gear (23) to the reverse idler shaft is axially slidable, from a neutral position, by a fork (48) connected by a lever (47) to a shift rod (46). The shift rods are selectively shiftable by a gear-shift-lever-actuable, rotatable (cross-shift) and slidable (gear-establishment), spindle 56 having an arm 55 the end of which is engageable in grooves of members 50 carried by the shift rods. A T-sectioned interlock member 52 engaging the grooves of the members 50 and movable with the arm 55 during cross-shift prevents simultaneous gearestablishing movement of more than one shift rod. A power take-off shaft 27 is driven through speed increasing gears 28, 29 respectively fast on the layshaft 13 and free on and clutchable to the shaft 27. A brake engageable on disengagement of the main, engine to input shaft, friction clutch (not shown) comprises a disc 60 fast on the input shaft and a shoe 59 carried by a lever 58 which is acted on by the clutch-actuating cross-shaft 57 through an arm 61, a rod 62, rod abutments 63, 64 and springs 65, 66.

Title: Light equalizer
IPC: G02B6/00
Filed: 1975-03-21
Abstract: 1489805 Lighting fittings ENVIRONMENTAL RESEARCH & TECHNOLOGY Inc 21 March 1975 [5 April 1974 (2)] 01938/76 Divided out of 1489804 Heading F4R A light equalizer designed to produce a substantially uniform light intensity across its output aperture 32 irrespective of intensity variations across its input aperture 26 comprises an elongated light-transmissive body 22 divided, in a direction extending between the apertures, into 2<SP>m</SP> transmission channels, where m is a positive integer, the channels having substantially identical transmission characteristics and at least a part of the interface between each pair of adjacent channels being substantially half reflective and half transmissive. The body 22 is divided in half on the plane A-A by a plurality of reflective elements 28, 30, 31 so that for a distance d1 extending inwardly from the input aperture 26 substantially half the plane A-A is reflective and the remainder transmissive whilst for the remainder of the length of the body the plane A-A is entirely reflective. At distance d 1 the two halves of the body are themselves divided in half on respective planes B-B and C-C by reflective elements 34-41 so that for a distance d2 each plane is half-reflective and half-transmissive whilst for the remainder of the length of the body each plane is entirely reflective. Further divisions are made in a similar manner. The reflective elements may consist of metallic foils or deposited coatings and the half-reflective half transmissive regions may consist of a continuous film of a suitable dielectric material. The light transmissive body 22 may be made of glass or a high molecular-weight polymer for use with visible light or an alkali-halide for use with infra-red radiation, the use of self-supporting reflective elements in a vacuum being also contemplated. The external surface of the body, except for the apertures 26, 32, is made reflective. A second body 24 with its reflective planes inclined, preferably at a right angle, to the reflective planes of the body 22 may be connected to the output aperture of the first body. In operation, radiation entering the aperture 26 at an inclination to the planes of division is split by the part-reflective, part transmissive regions so that it is distributed substantially equally between all of the channels. Radiation which enters parallel to the planes is not equalized, so a second equalizer disposed at an angle to the first may be connected to the output aperture of the first equalizer.
