Abstract: 343,543. Road rollers. BARFORD & PERKINS, Ltd. and PERKINS, J. E. S., Queen Street Iron Works, Queen Street, Peterborough. Nov. 15, 1929, No. 34951. [Class 6 (i).] Relates to road rollers of the kind wherein the usual pivoted yoke for the front axle is sprung and steering movement imparted to it by a sector or the like borne in the vehicle frame and slidably keyed to the yoke pivot. According to the present invention the sector or the like 9 is held to the frame 4 by bolt-and-slot connections 11, 12. In the construction shown the yoke 1 is pivoted to a pivot pin 2 slidable and rotatable in a bush 3 fixed to the frame 4. The frame is supported in the fork by means of bosses 8 on the bush, springs 7, and a non-rotary flange 6 resting on a flange 5 secured to the pin 2. The sector 9 is slidably keyed at 10 to the pin 2 and is rotated for steering by means of a shaft 14 and worm 13 engaging with teeth on the sector. Steering may be effected by hand or power, the hand gear comprising a hand-wheel (not shown), a shaft 16, and bevel gearing 17 driving the shaft 14. The power gearing comprises a shaft 23, Fig. 6, driven from the engine, bevel reversing gear 20a, 21, and a chain wheel 22 driving a chain wheel 27 on the shaft 14. The reversing gear is controlled by a hand-lever (not shown) on a shaft 36 connected by an arm 37 and bell-crank 38 with a sliding rod 39 acting through a block 40 and a rod 25 connecting friction clutches 24a, 24b which clutch the respective bevel wheels 20a to the shaft 23. Springs 41 on the rod 25 normally hold the rod 25 in the central position, and adjusting nuts 26 are provided. To prevent the yoke from being turned too far stops 30 on the sector are adapted to engage a lever 31 connected by a rod 34 to the rod 39 so as to disconnect the power steering- gear.

Title: Improvements in or relating to machines for cutting and stacking sheets of paper
Inventor: DAVIES ROY DENIS
IPC: B26D1/08
Filed: 1959-10-15
Abstract: 902,915. Delivering sheets. ERICSSON BROS. Ltd. Oct. 13, 1960 [Oct. 15, 1959], No. 34991/59. Class 100 (1). A machine for stacking sheets of paper comprises a cutting blade 1 movable to cut a web of paper into sheets, a stacking tray 15 on which the sheets fall and are stacked, and a presser plate 7 arranged for movement with and in relation to the blade 1, which plate engages the uppermost sheet of the stack and presses the stack and the tray 15 downwards. The blade 1 co-operates with a fixed blade 2 and the plate 7 is pivoted to the blade 1 at 8. A lever 9 is pivoted to the blade 1 at 10 and has a forked end which engages a pin 11 mounted on the plate 7. The free end of the plate 7 is biased upwards in relation to the blade 1 by a spring 13, but is held in the position shown, when the cutting blades are open, by an angled strip 7b secured to the flanged lower edge 7a thereof, which strip engages under an angled member 14a secured to the machine frame. The tray 15 is mounted on a framework 16 which includes vertical bars 17 slidable in flanged, channel-shaped guides 18 secured to the machine frame. Spring-biased friction washers 20 on the framework 16 engage the outsides of the guides 18 and normally prevent the bars 17 from sliding in the guides 18. A web of paper is advanced intermittently between the blades 1, 2. When the web is stationary the blade 1 descends and severs a sheet length therefrom. After the cut has been made the end 12 of the lever 9 engages the head of a screw 14b threaded in the member 14a causing the lever to pivot in an anti-clockwise direction and the plate 7 to pivot downwards until the flanged edge 7a engages the cut sheet, now resting on top of the pile on the tray 15. This pressure on the top of the pile overcomes the friction of the washers 20 so that the tray 15 is moved downwards a short distance. When the blade 1 is moved upwards away from the blade 2 the plate 7 is returned to its original position by the spring 13. The machine may be modified for cutting narrow depth sheets, in which case the tray 15 is pivoted downwards to a vertical position and a narrow depth stacking tray is secured thereto, guide plates being mounted on the framework 16 in order to retain the cut sheets on the tray. Specification 794,732 is referred to.

Title: Improvements in or relating to a process for the catalytic cracking of hydrocarbon oils
IPC: C10G11/18
Filed: 1957-11-18
Abstract: A hydrocarbon oil boiling essentially above the gasoline range is cracked to give gasoline by: (1) introducing it as vapour into a narrow first reaction zone together with 5-15 parts by weight (per part of oil) of a freshly regenerated finely-divided cracking catalyst and passing them as a suspension through the zone for a contact time of 1-4 seconds at a velocity (defined below) of 2.4-18 metres per sec. and above that at which the catalyst will fluidize, the conversion being at least 40 per cent; (2) separating hydrocarbon vapours and catalyst and passing the former together with hydrocarbon vapours from the second reaction zone (see below) to a fractionating zone where there are separated gasoline product and oil boiling essentially above gasoline; (3) part of the oil boiling above gasoline from the fractionating zone such that the combined feed ratio (defined below) is between 1.5 and 2.8 is passed to the second reaction zone, the remainder being withdrawn as product; (4) passing partially used catalyst from the first reaction zone to the second reaction zone where conditions are maintained for a contact period of at least 2 minutes and a conversion of 10-40 per cent, the temperature being below that in the first reaction zone; (5) separating catalyst from the hydrocarbon vapour effluent which latter is then passed to the fractionating zone.  The velocity is defined as the arithmetic average of the velocities at the beginning and end of the first reaction zone; the combined feed ratio is the ratio of the volume of feed passed to both reaction zones to that passed to the first reaction zone; first stage and total conversion are defined as 100 minus the percentage of oil recovered boiling above 232 DEG  C. (450 DEG  F.) from the first stage and total reaction products respectively, the difference between these being the second stage conversion.  The catalyst is conventional, e.g. silica-alumina or activated clay, it is preferably fluidized in the second reaction zone and may thereafter be regenerated and returned to the first reaction zone.  First stage reaction temperature is preferably at least 510 DEG  C. and may be up to 580 DEG  C.  The feed preferably contains less than 0.5 per cent boiling below 232 DEG  C.
