Abstract: 359,434. Drilling-machines; metalworking presses. GREENWOOD & BATLEY, Ltd., 16, Great George Street, London, and MACLAGAN, J. C. M., Grainge Villa, Wedgewood Drive, Roundhay, Leeds. July 17, 1930, No. 21715. [Classes 83 (iii) and 83 (iv).] In a machine having an automatic work-feeding device such as a drill or press, a number of workholders are moved radially and in succession into and out of working relationship with a central tool head. The invention applied to a press is shown in Figs. 1 and 2 where A indicates a work table supported on a body B which houses a centrally placed ram or die block C, adapted to work in conjunction with an adjustable press head D. Slidably mounted in radial grooves in the table A are guide blocks 2 ; a bolt passing through each block secures, on the upper face, the work-holder 4, and underneath the block, a link 5 which is attached to one arm 6 of a bell-crank lever fulcrumed on studs 7, fast to the table A, and whose other arm 8 carries a pin mounting a roller 9. The rollers 9 run in a cam groove 13 on a plate 10 which is rotated centrally about the die block by a worm and worm wheel; such rotation causes the work holders to reciprocate radially so that each is successively brought under the tool head for treatment, and then withdrawn to an outer position for emptying and recharging. A machine provided with three feeding members is shown, but more or less may be employed ; a double workholder may also be attached to each guide block, Fig. 4, in which case a cross lever 15 having two rollers 16, 16<1> is fastened to the underside of the blocks and the rollers arranged to engage cams 17, 18 on the plate 10, so that on rotation of the latter each of the work-holders on the feeding members is swung through 180‹ and brought, in turn, under the centre of the machine.

Title: An improved method of separating contamination from lubricating oil
IPC: F16N39/06
Filed: 1934-07-28
Abstract: <PICT:0442081/III/1> <PICT:0442081/III/2> In a process for regenerating used lubricating-oils, such as from internal combustion engines, the used oil is passed through a filter F, Fig. 1, and flows through a pipe p<3> to a still S from which diluent fuel vapours are drawn by a pump through a condenser C<1> and the condensate flows into a receiver FR. The regenerated oil flows through a pipe t into a reservoir OR, the top of which together with fuel receiver FR is connected to a vacuum pump VP.  The filter F may also be connected to the vacuum pump.  The still S consists of a series of superposed members a<1>--a<4>, Fig. 2, each having a central opening an extending above a circular annular well ar, at the base of which is a drain tube connected to the well of the member below.  A vertical plate having holes at the bottom is mounted in front of each drain tube to retain any froth.  The lowest member a<1> forms a sump for oil and is provided with an overflow pipe t.  The cover member a<5> contains a vapour outlet v, a safety valve s, and a thermostat t<9>. The members are heated by electrical resistances e to a temperature of 300 to 500 DEG  F., and the whole apparatus is mounted within a casing c.  In operation, the filtered oil is fed upwards through a pipe p<3> to the top member a<4>, and flows around the recess to the outlet pipe through which it descends to the next member a<3> in the series and finally into the sump a<1>.  During the downward flow, the diluent fuel is vaporized and passes through the central apertures to the outlet v.  The regenerated lubricating oil flows from the sump through the pipe t to the reservoir.  The members a<1>--a<4> are shaped so that a large cross-section of metal is provided through which heat flows, the cross-section decreasing towards the centre. Heating may be effected by superheated steam.

Title: Measuring and control apparatus
IPC: G05B11/01
Filed: 1937-08-11
Abstract: 493,229. Electric signalling systems. BROWN INSTRUMENT CO. Aug. 11, 1937, No. 22097. Convention date, Sept. 25, 1936. [Class 40 (i)] A motor is controlled by unbalance of a self-balancing electrical network, the motor driving in one direction when the bridge is unbalanced in one direction and driving in the reverse direction when the bridge is not unbalanced in this direction. The application of the invention to a means for indicating fluid flow in a pipe is shown in Fig. 1. When the flow varies the armature D is displaced so that an inductance bridge is unbalanced and armature d at the receiver is moved to restore balance. If d moves upwards it closes contacts f, F, so that motor E is driven to move contact F upwards, the pointer A<1> being moved at the same time over a suitable scale to indicate the flow. When contacts F and f separate the motor reverses and at once recloses contacts F, f, so that the motor oscillates about a position determined by the position of armature d. If d had moved downwards, motor E would have moved contact F downwards to follow f and the motor would have oscillated with arm G in a different position. Numerous constructions of contacts f, F and suitable motor circuits are described in the Specification. The Specification as open to inspection under Sect. 91 describes also a system using a light beam and a selenium cell J as shown in Fig. 14 (Cancelled). When the temperature of the thermocouple T varies the mirror K of the galvanometer M deflects the light beam which is directed towards the cell J so that motor E turns the turntable O on which cell J is mounted until normal circuit conditions are re-established and the motor E oscillates the table O to maintain the circuit in this condition. The table O may control a valve Q to maintain constant the temperature of the thermocouple and may carry a pointer to indicate temperature change. This subject-matter does not appear in the Specification as accepted.

Abstract: 1495843 Cracking oils MOBIL OIL CORP 22 May 1975 [17 June 1974] 22259/75 Heading C5E [Also in Division B1] Coked fluid zeolitic hydrocarbon conversion catalysts are regenerated by forming a mixture, having a temperature of at least 1175‹ F., of coked catalyst and hot regenerated catalyst, passing the mixture in suspension in oxygen-containing regeneration gases upwardly through a dense-bed regeneration zone and thence through a dispersedphase regeneration zone, the quantity of such gases in said zones being sufficient to raise the temperature of catalyst leaving said dispersed phase zone to at least 1350‹ F., collecting regenerated catalyst from said dispersed-phase zone and forming the mixture from part thereof. As described catalyst particles from the riser conversion zone 4 are separated in cyclones 14, 14<SP>1</SP> and collected as a downward moving bed 26 of catalyst through which stripping gas such as steam is passed as a countercurrent from conduit 28. Stripping gas and stripped hydrocarbons are separated in cyclone 16 and passed to a separator via conduit 24. Stripped catalyst withdrawn by standpipe 30 is passed to the bottom portion of riser mixing-catalyst regeneration zone 34, hot regenerated catalyst being added by standpipe 36. Riser 34 discharges into the lower portion of a dense fluid bed of catalyst to be regenerated. Regeneration gas is added via conduits 40, 42, 44. The density of the catalyst suspension is decreased as it ascends riser 46 the regenerated particles being discharged into settling zone 52 from which some regenerated catalyst is withdrawn by standpipe 36 for mixing with coked catalyst in riser 34 as described. The gases from settling zone 52 are discharged via cyclosers 54, 56. Regenerated catalyst is returned to the cracker via standpipe 5. The hydrocarbon feed to the cracker may be a gas oil and it may be cracked in the presence of additional gasiform reactant such as C 1-  5  hydrocarbons or the related alcohols or ethers. The products include gasoline, fuel oils and normally gaseous hydrocarbons.

Abstract: 504,529. Obtaining gases rich in hydrogen. METALLGES.AKT.-GES. July 26, 1938, No. 22260. Convention date, Sept. 27, 1937. [Classes 65 (i),and 55 (ii)] In the production of gas mixtures containing carbon monoxide and hydrogen in the volume ratio of about 1 to 2 for synthesis purposes by the gasefication of fuels under pressures of several atmospheres by means of oxygen-steam mixtures, the proportion of oxygen used being about 0À1 to 0À2 N.T.P. cubic metres per N.T.P. cubic metre of gas produced, carbon dioxide is added to the gasefication medium in amounts ranging from about half to three times the volume of oxygen employed. In an example, coke is gasefied under a pressure of 10 atmospheres with a gas mixture comprising about 0À13 cubic metre of O2, 0À65 kilograms of steam, and 0À2 cubic metre of CO2, to produce a gas,mixture in which the CO and H2 proportions comprise 21 and 42 per cent respectively. A pressure range of 5 to 50 atmospheres is specified and a gas mixture is produced which is practically free from methane. Carbon dioxide is washed from the gas mixture under pressure and a part is returned to the producer for adding to the gasefication medium. The CO2 may be heated to a temperature of 500‹ C. before entering the producer and it may also be saturated with steam to economise the latter in the process. Inferior tars or oils or gaseous hydrocarbons, such as methane, may be added to the gasefication medium and are cracked in the producer.
