Title: Improvements in or relating to cutter mechanisms for the webs of printing presses
IPC: B26D7/26
Filed: 1934-05-25
Abstract: 439,039. Printing - machines. GOSS PRINTING PRESS CO., 1535, South Paulina Street, Chicago, U.S.A.-(Assignees of Crafts, C. S.; 645, North Lombard Avenue, Oak Park, Illinois, U.S.A.) May 25, 1934, No. 15679. Convention date, June 19, 1933. [Class 100 (i)] [See also Group VIII] Cutting-apparatus folding paper.-Mechanism for cutting a printed paper web into sheets comprises a pair of rotary cylinders each carrying a shear cutter-blade, and so arranged that the cutting edges travel at speeds in excess of the web speed, and differing slightly from each other. The cylinders are formed with solid cores 15, 33, Fig. 1, rotated at equal angular speeds by intermeshing gears 31 at both ends, and are slightly inclined with reference to a line perpendicular to the line of feed. Integral lugs 16 on the core 15 carry the leading cutters 17 and are so shaped that when the cutters are secured by bolts 19, they assume a helical shape. The inner edges of the cutters abut against studs 22 screwed into the core and by the adjustment of which the outer edges of the cutters are caused to lie on a cylindrical surface. Discs of the diameter of this surface are formed on the ends of the cores so that straight edges can be placed thereon to form gauges for setting the blades. The following blades 30 are similarly attached to the core 33 except for the difference that the securing bolts 35 are adjustably secured to the lugs 32 by lock-nuts 391 and the blades are secured between collars 381 on the bolts and nuts 34. The coacting blade faces are curved so that the curves are a continuation one of the other. Also, the edges of the blades 17, 30 lie respectively just outside the pitch circle and on the pitch circle of the gears 31, which are arranged so that their speeds are slightly greater than the web speeds. Thus the blades move away from each other and from the cut edge of the web after the severing operation. Semi-cylindrical shells 25, 41 are secured to the cores 15, 33 respectively by bolts 26, 42, and their radius is such that their surface speed is that of the web. The cut sheets S are taken from the cutters at a speed greater than that of the cutters, and for this purpose the surface of the succeeding folding- cylinder 45, Fig. 8, between the grippers 47 and a corresponding folding blade 46 is formed of gradually increasing radius.

A needling machine comprises means to displace a part of the web W between the needle bed 1 and a continuously rotating draw roller 12 so that when the needles 3 are withdrawn the web can be drawn across the bed 1 faster than the roller 12 takes it up so that a surplus length of web is wound on to or passes around the roller 12 whilst the part of the web being needled remains stationary. The needles 3 operate through a stripper plate 2 and are mounted on a needle board 4 carried by a needle arm 5 reciprocated vertically by at least two crank arms 6 whose upper ends are eccentrically mounted on a drive-shaft 7. The roller 12 upon which or over which the web W is wound or passes is driven by a motor 8 and may have a pressure roller 13 co-operating therewith. A shaft 19 is driven at half the speed of the shaft 7 by the linkage shown. An arm 20 is secured near each end of the shaft 19 and carries the ends of two freely rotatable rollers 21 or rods or a series of rollers extending the width of the web to periodically contact and elevate the web. When the needles 3 are withdrawn a roller 21 elevates the web from the position W2 to the position W1 so that the slack part of the web is taken up by the roller 12 whilst needling takes place. In a modification, Fig. 4, the web is displaced by a freely rotatable roller 31 mounted between levers 33 pivoted at 34 and connected at their other ends by links 35 to rotatable eccentric devices 36 driven by the shaft 7. In further modifications (not shown) the web is elevated by a rail or free roller which reciprocates vertically or is taken around a system of rollers or rods which are reciprocated or moved relative to each other. The invention may also be applied to machines using upward needling.

Title: Surface treatment of metals
Inventor: WEATHERLEY ERIC GEORGE
IPC: C23C12/02
Filed: 1959-05-08
Abstract: Boron and a metal other than iron are simultaneously diffused into the surface layer of a metal article.  Suitable metals for codiffusion with boron are chromium, zinc, vanadium, niobium manganese, tantalum, tungsten and aluminium.  The metal article may be ferrous, e.g. mild steel, or a nickel-chromium or tungsten alloy. Diffusion may be effected by burying the article in a mixture comprising an inert, solid carrier, e.g. sand, boron or a boron compound, e.g. boric acid or sodium phenyl boron, and powdered metal or metal halide, and then heating in a sealed container. Alternatively, the article may be coated with a paste consisting, for example, of sodium tetraborate and sodium chromate and heated in an induction coil.  Diffusion may also be effected electrolytically (see Group XXXVI).

Abstract: 560,308. Hydraulic transmission of power. AUTOMOTIVE PRODUCTS CO., Ltd., and SIMPSON, J. K. Nov. 12, 1942, No. 16026. [Class 69 (ii)] In a liquid pressure remote control system comprising transmitting and receiving cylinders 12, 16 movement of the transmitting piston to the end of its stroke opens a valve 29 to connect the line to a pressure source 38, e.g. an accumulator or pump, whereby any leakage is made up and the motor piston is forced to the end of its travel. In the two-pipe system shown the opposite end of the transmitter is simultaneously connected to a reservoir 40. The valve is normally centralised by a spring 28 all connec - tions to the cylinder being closed until a projection 51 on the rod 13 engages abutments 49, 50 on the valve rod near the ends of the stroke. In a single pipe system the valve connects the system to a pressure source at. the end of the pressure stroke and to a reservoir at the end of the return stroke. Fig. 3 shows a system in which the transmitter and motor. pistons 93, 98 are hollow and form cylinders for secondary transmitter and motor pistons 94, 99 operable independently. The rods 95, 96 of the two transmitters actuate valves 103, 102 to connect their respective cylinder ends to a pressure source and to a reservoir when both transmitter pistons reach the same end of their strokes. The transmitter rods may be connected respectively to parts of a searchlight moving in planes at right angles, the motor rods being similarly connected to a second searchlight whereby the two lights move in unison. Alternatively the device might connect a machine gun &c. to a remote sighting device.

Title: Improvements in and relating to variable speed and reversing gearing
IPC: F16H3/72
Filed: 1927-06-16
Abstract: 300,928. Richardson, E. June 16, 1927. Variable-speed and reversing gearing comprises a three-element spur train b, c, e, Fig. 1, controlled by an hydraulic reciprocating pump carried by a drum m, which is secured to the carrier d of the planets c. A driving-shaft a carries fixed thereto the sun gear b and a face cam k. Fast on a driven shaft f is the internally-toothed ring e. Relative motion of the loose carrier d causes the cam k to reciprocate pistons h in two cylinders g. The rear ends of the cylinders communicate by an annular passage n, Fig. 3, and oil passing to and fro between the cylinders is throttled by a valve controlled by displacement of a sleeve g<16> on the shaft a. In the arrangement shown, the valve is constituted by a lining g<2> within one cylinder which can be turned round so as to vary the opening at g<5> into the channel n, there being ports g<4>, g<5> in the lining and in the cylinder wall. This turning is effected from sliding sleeve g<16> through a lever linkage g<14>, g<8>, g', g<6> and spigot g<3>. The cam k and coacting bowls h<2> on the piston rod ends have bevel surfaces like bevel friction gears. The sleeve g<16> is operated in turn by a sliding cam bar t which has a flat t<2> for holding the valve g<5> fully open while through a linkage v it gradually applies a brake u to the drum m to effect variable reversed drives. Alternatively the cylinders g may be arranged radially in the drum m and the cam k may be replaced by an eccentric or crank. The throttling may be effected by the relative displacement of plates each having a triangular opening.
