Title: Self loading vehicles
IPC: B66F9/06
Filed: 1973-03-06
Abstract: 1364585 Self loading vehicles; fork lift trucks J A FARGEN 6 March 1973 [6 March 1972] 10413/72 Headings B8E and B8H [Also in Division B7] A self-loading fork lift vehicle having its power unit and transmission slung under the load platform has the forks rotatable through 190 degrees about a vertical column and three conveyers in series to feed loads to the end of the vehicle. The first conveyer 18 comprising powered rollers as described is at 10 degrees to the longitudinal centre line of the vehicle while the second conveyer 19 is pivotally mounted at 23 to be alignable with the first or third conveyers 18, 20 by the action of a ram. The conveyers are provided with clamping strips having pressure pads 51, Figs. 8, 8A, actuated by a ram 58 to move a section 50 so that a load is gripped to align it on the conveyer 18 or to hold it during transport on conveyers 19, 20. The forks are mounted on a sub-frame 37, Fig. 6, secured to a framework running by rollers 35, Fig. 2, on the column 15 and movable thereon by a ram acting through a chain and pulley mechanism. The frame 37 can tilt the forks by a ram 41 acting through links 45.  A stabilizing pad 25 pivotally mounted on the vehicle, Figs. 3, 7, is connected by linkwork to a side rail 26 so that on operation of a ram 48 to raise or lower the pad the rail is correspondingly raised or lowered. Safety limit switches are provided to prevent operation of the parts out of sequence, e.g. to prevent swivelling of the forks while the pad 25 and rail 26 are raised.

Abstract: 678,749. Lathe details. WICKMAN, Ltd., A. C. April 4, 1951 [April 28, 1950], No. 10464/50. Class 83 (iii). Tool-slide actuating mechanism for a multispindle lathe &c. of the kind giving rapid movement up to the work, slow cutting feed, and quick return, comprises the combination of a slide, a toggle mechanism connected to the slide, a two-armed lever carried by the slide and adapted at one end to actuate a tool-slide, an adjustable link and lever mechanism connected to the other end of the lever, and rotary cams for actuating the toggle, link and lever mechanisms. A slide b has pivoted thereto a lever d, one end of which may be connected directly to the tool-slide, or, a link r may connect it to the tool slide s as shown. The other end of lever d is adjustably-connected by a link k to a doublearmed lever n pivoted to the frame at o. One end of lever n has a roller p which engages a cam groove q in a rotatable disc i. The slide b is also connected to one link e of a toggle mechanism e, f. Link f of this mechanism carries a roller g which engages a cam-groove h in the face of the disc i opposite to that with the cam-groove q. As the toggle links straighten the tool-slide moves rapidly up to the work and the slow feed movement is obtained from movement of the lever n.

Title: Process for the manufacture of solid porous articles from polyolefins
IPC: B01D39/16
Filed: 1961-03-23
Abstract: Porous polyolefins are made by sintering a mixture of at least two particulate polyolefins, one of which has a softening temperature at least 5 DEG C. higher than another and also has a molecular weight at least twice that of the other. The polyolefins are homopolymers or copolymers of one or more of ethylene, propylene, butylene and branched alpha-olefins.  They may be produced by using Ziegler-Natta catalysts or by the "Phillips" or "Stanolind" processes and may have molecular weights of 10,000-1,000,000. The mixture may also contain organic or inorganic colourants or fillers (e.g. carbon black, blast furnace fly ash, kieselguhr or sawdust), a stabilizer (e.g. N-phenyl -N1- cyclohexyl -p-phenylene diamine), or a vinyl polymerization catalyst (e.g. benzoyl peroxide or benzene-1:3-catalyst (e.g. benzoyl peroxide or benzene-1:3-disulphohydrazide). The polyolefin mixture is sintered in a mould at 130 DEG -250 DEG C., preferably in an inert atmosphere or with exclusion of air, at atmospheric or higher pressures.  The mould may be previously treated with a release agent (e.g. calcium stearate, a polyhydric alcohol or ether thereof, or a silicone). Uses: gas and liquid filtration, heat insulating material, floating bodies, upholstery, fenders for boats, electrolytical membranes, in storage batteries, air cushions in textiles and packing, flower pots.

Title: A device for use in practising golf
IPC: A63B69/00
Filed: 1922-04-20
Abstract: 193,321. Stokoe, T. R. April 20, 1922. Golf-practising appliances. - A device for practising golf comprises two balls or a ball and a counterweight carried on an arm freely mounted on an horizontal spindle in a casing the surface of which is flush with the ground, the arrangement being such that the ball or the arm is capable of rotation about an axis at right angles to the spindle to give a visible indication of deviation of the ball from the direct path. In Fig. 1 the ball a is free to rotate on an arm b rotatable upon ball bearings arranged on an horizontal spindle c. A black line k is marked on the ball and indicates by its displacement the deviation in flight which would have resulted from the stroke. In a modification, Figs. 3 and 4, two balls n are rotatably carried on the arm i by spindles 1 and the arm is mounted on a ball bearing arranged upon a fixed spindle m. The ball bearing is such that the arm l may rock so as to rotate in a plane inclined to the spindle m if a deviating stroke is made. To indicate this deviation the arm l is coupled by links t to a pointer v which registers against a graduated scale at the top of the casing. The hub of the arm l is connected by a flexible shaft y to a counter indicating the length of the drive.

Abstract: 1,055,736. Friction and belt gearing; stopping and starting. W. KRATZSCH. March 17, 1964 [April 18, 1963; Dec. 31, 1963], No. 11296/64. Headings F2L and F2Q. In a friction drive from a wheel 4 to a wheel 24 frictional contact is maintained by drive torque reaction by mounting the wheel 4 and its drive motor eccentrically in a rotatable block 2 rotatable by a handle 17 to disengage the drive and brake the driven wheel 24. The motor and wheel 4 are also loaded against the driven wheel 24 by springs 15 and 11. In a modification, Fig. 3 (not shown), the drive wheel 4 is swung through 180 degrees to reengage the driven wheel and the handle 17 during this movement switches-off and then restarts the motor in reverse. In Fig. 10 (not shown), the handle 17 applies an internal brake to the driven wheel. The drive wheel may be stepped for multi-ratio drive and move axially with its eccentric housing by a gear 34, Fig. 5 (not shown), operated by hand wheel 39 which when swung laterally disengages the friction drive through linkage 36-37. For a flat or V-belt drive a belt is passed around the driving and driven wheels, rotation of the drive wheel in its eccentric housing decreasing belt tension sufficiently to stop drive transmission. In Figs. 11 and 12 (not shown), a belt drive wheel drives a wheel 67 mounted with a friction gear-wheel 71 on eccentricallymounted spindle 68.

Title: Improvements in or relating to the preparation of catalytic bodies
IPC: B01J37/00
Filed: 1923-04-26
Abstract: In the preparations of a porous catalytic material by treatment of a mixture of a metallic oxide or oxides and an organic metal compound or compounds with a carbonaceous reducing agent as described in Specification 5847/14, partial reduction is first effected and the reduction then completed at a higher p  temperature after the addition of further quantities of the reducing agent.  A mixture of the ground metal oxides with the organic metal compounds is briquetted with the carbonaceous reducing agent, such as tar, and preferably with the addition of a little carbon, and heated to a temperature of 700-800 DEG  C.; the heating is stopped before the oxide is reduced, the mixture re-ground, mixed with more tar and carbon again briquetted and roasted at a temperature of 1000-1100 DEG C. until the metal is obtained in the sintered form.  The carbonaceous reducing agent is preferably employed in each stage in the proportion of ten per cent of the total mass, any carbon added being in the proportion of about one per cent.  The oxides and organic compounds employed are usually those of the heavy metals, such as iron, nickel, cobalt and manganese.  Small quantities of a reducing metal, such as aluminium or magnesium, may be added to facilitate the reduction of the oxides.  In the examples the following mixtures are used, (1) ferric oxide, nickel oxide, ferrous oxalate, nickel oxalate and carbon, (2) ferric oxide, manganous carbonate, ferrous oxalate, carbon and aluminium, (3) ferric oxide, nickel oxide, iron tartrate, nickel acetate and aluminium.
