Title: Improvements in or relating to a process and apparatus for the treatment of contaminated oils
IPC: C10M175/00
Filed: 1943-10-05
Abstract: 573,386. Treatment of contaminated mineral oils. GENTIL, H. L. Oct. 5, 1943, No. 16319. [Classes 32 and 91] In a process for the recovery of usable oil from contaminated lubricating oil in a gravitational flow system in which the rate of flow is under control, the contaminated oil is subjected to filtration, and possibly also to neutralisation, and then the temperature of the oil is raised in at least two successive stages to temperatures which are below the temperature distillation range of the oil, with separate recovery of contained materials volatile at each stage; the refined oil is then cooled by heat exchange with contaminated oil. In the apparatus shown, contaminated oil is admitted through funnel 1 and passes through the filtering device 2 which is formed with alternating layers of powdered charcoal and sawdust admixed with a small quantity of quicklime. The filtered oil enters the reservoir 3 where it is electrically heated to about 50 to 60‹C., passes through the main control valve 4 into the heat exchanger 5 and from thence into boiler 6 where it is electrically heated to about 130 to 150‹C. The volatile material, which includes petrol, evolved at this stage is condensed in condenser 7a and collected in vessel X. The oil now passes through pipe 8a into heat exchanger 8 and from there into boiler 9 where it is electrically heated to about 300‹C. The volatile material, kerosine &c. evolved at this stage is condensed in condenser 10a and collected in vessel Y. The refined oil now reverses its flow, passing in order through pipe 11, heat exchanger 8 and heat exchanger 5, from which it emerges as a cool clear oil and is collected in vessel Z. In a modification of the apparatus, the heat exchangers and boilers are arranged as a series of nested concentric tubes. The process can be applied to the refining of oil tank bottom waste and of oil works slops from solid particles, water and petrol.

Title: Improved means of control for electrically driven vehicles
IPC: H02P9/00
Filed: 1926-06-29
Abstract: 278,073. Stevens, W. A. June 29, 1926. Systems for. ccntinuous-current motors; safety arrangements and connections ; controllers, interlocking.-In an electrically propelled vehicle driven by a compound-wound motor 1, the motor is controlled by a reversing switch 9 and a starting and speed-changing resistance controller 22. The reversing switch is actuated by a lever 18 having two extreme positions F, R for forward and reverse running and an intermediate neutral or off position N; the resistance controller is actuated by a spring-retracted pedal 24. The reversing lever and the pedal are interlocked, for example by the disposition of interengaging parts 29, 31 shown in the Figures, so that the reversing lever is free only when the pedal is fully retracted with the motor circuit broken and all the series resistance 4 connected in the line, and so that the pedal is free to be fully depressed only when the reversing lever has been set to the forward position, as shown in Fig. 2, and is free to be partly depressed when the reversing lever has been set on the reverse side, as shown in Fig. 3. In the forward running position shown in Fig. 2 the first part of the pedal movement acts, by means of a controller segment 21, to complete the motor circuit through a contactor 16 and to cut-out the series resistance step-bystep through contactors 16 - - 16<x>. The second part of the pedal movement, by means of a controller segment 27, puts resistance 5 step-by-step into the shunt field 3. In the reverse running position shown in Fig. 3 the pedal is prevented from going beyond the first part of its movement. To guard against undue rise of the voltage during regeneration a contactor 16 is adapted to open automatically in case of breakage or disconnection from the supply, a supplementary high resistance 32 being thereby connected in circuit with the shunt field. The invention is designed for use on overhead trolly vehicles, or on petrol-electric or battery vehicles.

Abstract: 317,313. Camco (Machinery), Ltd., (Assignees of Holms, W.). Aug. 13, 1928 [Convention date]. Delivery apparatus. - Sheets being delivered from a folding or other machine. 10 are directed to different receiving units by means of a deflector 41 rotatable in one direction only to various positions, stop members actuated by the travel of a sheet being adapted to control the rotation of the deflector in order to direct a succeeding sheet into a different course. The delivery mechanism is mounted in a frame 15 detachable from the main machine. Alternate sheets issuing from feed-rollers 17, 18 are directed by the deflector 41 between feed-rollers 26, 28 or 29, 34 respectively having pivoted shoes 49, 50 resiliently mounted and projecting into the path of the sheets as described in Specification 315,692. The spindle 42 on which the deflector 41 is carried is driven from a continuously rotating shaft through a friction clutch which slips when the deflector 41 is held against rotation so as to deflect a sheet upwardly between the rollers 26, 28 by an engaging hook 73 mounted on a spindle. 71 connected by links 67, 69 to a crank 65 on the shaft of the shoe 49. As the edge of the sheet moves forward it engages the shoe 49 and tilts it into the position shown dotted, and this movement is transmitted to the hook 73 by the mechanism 67, 69 so as to allow the deflector to rotate. A spindle 72 coupled to the lower shoe 50 by mechanism 70, 68, 66 similar to the mechanism 69, 67, 65 carrier a stop member 74 which arrests the deflector in position to direct the succeeding sheet to the rollers 29, 34 and releases it when this sheet engages the shoe 50 so as to allow the deflector to move to its initial position. The hook 73 and the stop 74 are provided with resilient adjusting mechanisms 75, 76 respectively. The mechanism may be modified so that consecutive sheets may be directed into any desired number of different paths. Specification 308,352 also is referred to.

Abstract: 321,661. Carpmael, A., (I. G. Farbenindustrie Akt.-Ges.). Aug. 9, 1928. Cellulose ethers. - Water-insoluble cellulose ethers, are purified by extraction with a mixture of water and a water-soluble solvent, whereby the constituents of the ether which are of low viscosity and swell in water are removed. The, extracting agent may be dilute alcohol, dilute acetone, or dilute acetic acid. To improve the colour of the product, there may be added to the extracting agent a small proportion of an alkali and/or of a bleaching agent such as hydrogen peroxide. The low-viscosity constituents taken up by the extracting agent can be precipitated therefrom by addition of electrolytes. Examples describe the purification of ethyl cellulose with dilute alcohol alone or with an addition of caustic soda or caustic soda and hydrogen peroxide; in each example, the extraction is effected at ordinary temperature, but higher temperatures can be applied if the extracting agent is modified. Purification as described above renders the cellulose ethers more suitable for use in the manufacture of artificial threads, plastic masses, and lacquers.
