Abstract: 128,041. Davies, E. A., and Cryer, A. July 12, 1918. Cagc Lifts.-In a double-cage system, the hoisting rope A on its way to and from the driving pulley E is passed round pulleys D, D<1> mounted loosely on a shaft P which can be raised and lowered in the guides H by means of a screw R actuated by a motor Q. After the installation of a new hoisting rope, the shaft P is placed near the top of the guides, and if the rope stretches in use, the shaft is moved downwards until the portion of the rope between the pulleys on the pit head framing L and the cages is shortened sufficiently to allow the cages to arrive simultaneously at the top and bottom of the shaft. The rope A is pressed against the pulley E by a guide-pulley F. A rope reel K driven by the main motor T is provided for installing the hoisting rope in the first instance and for storing a spare hoisting rope.

Title: Method of and apparatus for extracting maleic anhydride from a gaseous mixture
IPC: B01D5/00
Filed: 1959-04-03
Abstract: Maleic anhydride is extracted from a gaseous mixture containing it, e.g. gases originating from the catalytic oxidation of hydrocarbons such as benzene, by passing the mixture through a cooling <PICT:0909645/III/1> zone to condense the anhydride to a liquid which is removed as it is formed at a plurality of locations spaced apart along the path of flow of the gaseous mixture.  In Fig. 1 cooling is by means of a fluid, preferably water, which circulates through a bank of horizontal tubes 2 and maintains them at 53 DEG  to 55 DEG C., the maleic abhydride condensing at 54 DEG  to 58 DEG C. from the gaseous mixture and flowing into funnels 13 and thence to a pipe 18. The height of the bank is small compared with the path of flow of the gaseous mixture so that reaction of the condensed anhydride with water vapour in the gaseous mixture is minimized by quick removal of the anhydride from vessel 1.

Abstract: 1,215,064. Abrasive wheel. E. SCHOLZ and H. SCHOLZ, [trading as BAYERISCHE MASCHINENFABRIK. F.J. SCHLAGETER. 11 March, 1968 [2 Sept., 1967], No. 11740/68. Heading B3D. A cutting and finishing wheel for stone or artificial stone workpieces is divided at its periphery into segments which are separated by cooling-water channels supplied by internal passages and each of which is provided with a radially projecting diamond segment. The workpiece may be a staircase step, a flagstone or a window sill. The underside of a wheel 1 has radially extending milled channels 3, adjoining an annular duct 2; the segments formed by the channels are provided at their outer periphery with diamond segments 5 projecting radially outwards a little beyond the outer periphery of the wheel. Passages 6 connect the channels 3 to an annular cooling-water chamber 7 in the wheel having an opening 8 through which cooling water is continuously supplied through a pipe 9. Water is forced by centrifugal force into the channels 3 to reach the diamond segments. Excess water can collect in the duct 2. The wheel cuts horizontally through the workpiece in a single cut, the surface of the workpiece left above the diamond segments 5 being broken away upwards by the wall 10 of the wheel which tapers conically towards the diamond segments. The diamond segments may flare axially inwardly from the projecting front cutting surface. The wheel may be fitted with a second similar wheel 14, Fig. 5, with diamond segments 15, for working stepped workpieces.

[Class 87 (ii)] [Also in Group X] A mould 12, Fig. 16, for a concrete plate or slab 1 is lined at 15 with several plies of builders' paper joined together by an asphaltic or other waterproof composition. The bottom member 113 with recesses 112 may be made of aluminium, and has two integrally formed opposite sides 114, 115, the two other sides being secured by hinges 125 to depending flanges 117 on the bottom plate, so that the mould may be opened by swinging out two opposite side members which are held in place by bolts 126 extending between wings 127 on the side walls 114, 115. Core rods 135 are passed through the recesses, and through lugs 137 by which they are supported, these rods forming holes in the pillars of the formed slabs. The mould is mounted on a rectangular frame 140, 142 by fastening screws 143, and is clamped on to a vibrating table for the concrete mixture to be poured. The paper, after the moulding operation, adheres to the slab 1 and prevents the newly-cast article from slumping. After the mould is reversed and the slab 1 stripped therefrom upon a pallet, strong adhesion of the paper to the slab is obtained by steaming in a kiln.

Abstract: 571,827. Valves. TECALEMIT, Ltd., and LE CLAIR, C. C. S. July 22, 1943, No. 11961. [Class 135] A valve device opened by hand and retained in the open position by detent devices released after a predetermined flow by a fluid meter is arranged so that the valve is closed in two or more stages so that the completion of the desired quantity is effected at a reduced rate. In the form shown in the Figures, the valve 25 has a facing washer 20 adapted to co-operate with a seat 21 and is opened by a hand lever 22 pivoted between a pair of brackets 23. The valve is held in the fully-open position by a spring-pressed catch 32 engaging an extension 22a of the lever, a similar catch 31 being provided to hold the valve in the partly-closed position. When both catches are released, the valve is slowly closed by a spring 30 and by conduit fluid passing through restricted apertures 26a, 27a to act on a piston part of the valve member slidably mounted in a cylinder 28. The catch 32 is carried by a shaft 35 provided with a crank arm with a pin engaging a slot in the end of a link 40 adjustably connected to a crank arm 43 on a shaft 7. The other catch is similarly coupled to an arm 53 on a second shaft 8 coaxial with the shaft 7. A drum 6 provided with a notch 16a is secured to a shaft rotated by the liquid meter 2. A series of drums frictionally mounted on this shaft are each formed with a semicylindrical notch and are provided with numerals 0-9 visible one at a time through a window. The drums are driven cyclometer fashion so that they indicate respectively units, tens and hundreds of gallons. The position of each drum relative to the drum 6 is preset by depressing a plunger 51 carrying a pawl co-operating with a ratchet wheel secured to the drum. The shaft 7 carries three arms 9, 10, 11 having rollers pressed into engagement with the drums by a spring 17. When the three drums have returned to their zero position, the rollers fall into the notches and the catch holding the valve fully open is released. Thereafter, when the drum 6 reaches its zero position, a sharp-edged projection on an arm 15 secured to the shaft 8 falls into the notch 16a and releases the second catch, so permitting final closure of the valve. The arms 11 and 15 are provided with interengaging projections to prevent the arm 15 operating and to hold the sharp edge out of contact with the drum until the first catch has been released.
