Title: Improvements in the method of, and apparatus for, continuously distilling liquid hydrocarbons of the benzol type and the like
IPC: C07C7/04
Filed: 1924-02-09
Abstract: 232,724. Koppers Coke Oven Co., Ltd., (Koppers, H.). Feb. 9, 1924. Hydrocarbons, distilling; progressive evaporators.-In distilling benzol, &c. from wash oils, the apparatus is arranged so that circulation of the oil is not affected by the degree of reduced pressure in the apparatus. A pump 11 draws wash oil from a container 10 and forces it through a heat-exchanger 12 and pipe 15 into a still 14. The residual oil passes by a pipe 13 through the heat-exchanger 12, where it acts as heating- agent for the incoming oil, and to a stand-pipe 17 which is discharged at a constant level by a pipe 18, so as to maintain the exchanger 12 full of oil. Vapours pass from the still to a column 21 and a cooler 22 connected to a vacuum pump 23. The still 14 consists of an inclined vessel fitted with staggered partitions 30 and heated by gas burners 25, the hot gases from which pass through a preheater 26 for the air supply to the burners, the heated air being supplied through perforated pipes 29 below the burners.

Title: Improvements in or relating to polymer-inorganic support composites
IPC: C08F2/46
Filed: 1966-01-26
Abstract: Polymer-inorganic support composites having semi-conducting and catalytic properties are prepared by contacting a polymerizable, unsaturated monomer, under radioactive radiation and in the vapour phase, with a solid porous inert inorganic support having a specific surface area of from 100-500 sq.m/g.  (The polymer formed is stated to be "grafted" on to the support.)  Monomers specified are vinyl chloride, vinyl acetate, divinyl benzene, vinylidene chloride, acrylonitrile, methacrylonitrile, hexyne-1, octyne-1, cyclohexyl-acetylene and phenyl-acetylene.  The support may be a silica, alumina or silico-aluminate.  The radiation may be alpha rays, beta rays, neutron fluxes, X-rays or gamma radiation, e.g. from an isotope such as cobalt 60.  Polymerization may be effected at ambient or elevated temperature. In some cases, it is necessary to submit the product to a thermal and/or chemical after treatment, e.g. pyrolysis, oxidation or dehydrochlorination. In examples, acrylonitrile is polymerized on to alumina or a silico-aluminate, the composite being subsequently heated at 500 DEG  C in a current of helium; the product can be used as a dehydrogenation catalyst (see Division C5).ALSO:A composite material prepared by polymerizing acrylonitrile vapour on a porous support of alumina or a silico-aluminate (see Division C3) is used as a dehydrogenation catalyst for converting cyclohexane to benzene, and butene-2 to butadiene (together with some butene-1 formed by isomerization).  The reaction is conducted at 500 DEG  C.

Title: Improvements in or relating to the control of an internal combustion engine-electricpower plant as used for the propulsion of a vehicle
IPC: H02P9/00
Filed: 1945-02-12
Abstract: 592,201. Control of D.C. motors. SULZER FRERES SOC. ANON. Feb. 12, 1945, No. 3460. Convention date, March 9, 1944. Addition to 592,193. [Class 38 (iii)] [Also in, Group XXXV] To avoid overloading of the contacts of the motor field regulator switch in a control system for an internal - combustion engine-electric vehicle drive 1-4 as described in the parent Specification, means are provided to ensure that the moving contact of the switch, in moving from one fixed contact to another, comes to rest only when completely engaging a fixed contact. In the system shown, control of the field accelerator resistors 30, 31 of motor 4 is effected by a drum controller 60 actuated by a reversible electric servomotor 56 - 58, the energization and direction of rotation of the latter being under the control of contacts 53-55 associated with the generator voltage regulating servomotor 12. Positive engagement of the drum contacts 73-77 with the drum is effected by a notched plate 65, which rotates with the drum, and a locking bar 66 having a tongue 66<1> for entering the notches. The bar is supported on springs 69, 72 and is moved into ' release ' position to allow rotation of the drum by electromagnets 67, 70, one of which becomes energized when contact 53 engages either of contacts 54, 55. When this occurs servomotor 56-58 starts up and runs until contact 53 is again clear of 54, 55. The energization of the servomotor and electro-magnet then ceases and the momentum of the drum rotates the latter until tongue 66<1> springs into the next notch. Alternatively, the drum controller may haul additional contacts 61-64, 78, 79, which together with contacts 68, 71, actuated by the electromagnets, permit further energization of the servomotor to the extent necessary for the engagement of the tongue with the next notch. A modified arrangement makes use of a single electro-magnet.

[Classes 54 and 69 (i)] Gas or volatile liquid is stored in a container comprising a vertically movable member attached to the side wall of the container by a flexible sealing member which forms a loop depending from the vertical movable member substantially throughout its vertical movement. Fig. 2 shows a storage tank A in which the top of the storage chamber is formed a vertically movable member B which is attached to the side-wall 2 by a flexible non-metallic sealing member C. The member B is supported by cables 3 attached to counterweights 5 which are equal to or slightly greater in weight than the member B and its attachments. In the loop of the sealing member C are arranged roller weights 29 strinig on a ring 30. The sheaves 4 over which the cables 3 pass are mounted on a roof D carried by' a cylindrical shell 7 supported by the side-wall 2. The memver C is prevented from sticking to the side-wall 2 and shell 7 by insulating material 14. The member B is preferably formed by a limber metal diaphragm capable of flexing upwardly and downwardly to vary the volume of the storage chamber. The bottom of the tank is rigid, if the tank is to be used as a gas holder, but preferably consists of a limber metal diaphragm 1, if the tank is to be used as a combined gas and liquid holder. The vertical movement of the member B is limited by stops 12, 13. Excessive pressure in the storage chamber is relieved by an escape valve 17 in a tubular neck 15 on the member B being operated by engagement with an adjustable tripping device 21 in a canopy D<1> supported above the roof D. A flexible sealing device 20 engages around the neck 15 as it issues from the roof D and prevents the gas entering the shell 7. An excessive vacuum in the storage chamber is prevented by a relief valve 24 on the member B opened by the bottom 1 when it flexes upwards. Gas and liquid are supplied to or withdrawn from the storage chamber through pipes 10, 11, Fig. 8 shows a gas holder consisting of an inverted cup-shaped member A' supported on posts or an annular shell E<1>, the bottom of the storage chamber being formed by a piston or vertically movable member B<1> attached to the side-wall 101 by a flexible element C<1> carrying roller weights 107. The member B<1> is counterbalanced by weights 105 attached to cables D<1> passing through stuffing-boxes 108 which may be lined with felt or arranged below reservoirs 109 containing a viscous sealing liquid. The sealing liquid flowing down the cables is caught in cups 110 on the piston B and passes through syphon drains 111 to a reservoir 112. A pressure vacuum vent 113 may be provided on the gas inlet and outlet pipe 114. Specification 470,086 is referred to.

Abstract: 931,621. Feeding sheets. BAFRA MASCHINEN G.m.b.H. Jan. 29, 1960 [April 23, 1959], No. 3354/60. Class 100 (1). [Also in Group XVII] An apparatus for sealing envelopes by folding down their flaps into contact with a glue moistening device is arranged to operate in combination with franking means to which it may  feed envelopes in spaced formation. Envelopes to be sealed are stacked with their closure flaps 21 vertical in a magazine, one side 13 of which is adjustable for different sizes. They are fed forward by belts 6 protruding through a plate 8 supporting the magazine and pivoted at one end so that a cam 10 operating on a roller 11 at the other, may raise it clear of the belts to stop the feed. Rubber plates 17 lie on the belts 6 and allow only one envelope at a time to pass. Each envelope is passed by a belt 24 and with its flap still vertical, beneath a plate 27 and a plough 38 then folds the flap on to a brush 37 moistened from a tank 34. The envelope is fed between rollers 22, 40 to complete the seal. The envelope may pass to a franking machine 41 of known kind in which case the cam 11 is permitted to oscillate the magazine to give a spaced feed. For sealing only, however, the cam is moved clear of the roller 11 to give a continuous feed. Means may be provided to interrupt the feed if the franking machine should cease operation. The apparatus may forward cards or printed matter, the closing means then being inoperative.

Filed: 1958-02-06
Abstract: The invention comprises the lithium salts of 1,3 - dimethylcyclobutane carboxylic acid, 1,2,2,3 - tetramethylcyclopentane carboxylic acid, 1,3,3 - trimethylcyclohexane carboxylic acid, 1,4 - diisopropylcyclohexane carboxylic acid, 2,2-diethylhexanoic acid, 2-methyl-2-cyclohexylpropionic acid and 2-methyl-2-ethyl-butyric acid.  Lithium compounds of tertiary carboxylic acids may be prepared by reacting the appropriate acidic organic compound with lithium or lithium hydride, hydroxide, alkoxide or carbonate, followed by recovery of the salt from solution in water, alcohol or an inert organic solvent. Alternatively they may be prepared by saponification of an ester of a tertiary carboxylic acid with a lithium base.  The salts are useful as additives for fuels for internal-combustion engines, and a number of salts suitable for this purpose are specified in addition to the above.ALSO:A hydrocarbon fuel for internal combustion engines contains, as anti-knock agent, from 0.05 gm. to 50 gm. per gallon of a lithium salt of a tertiary carboxylic acid.  Suitable lithium salts include those of 1,3-dimethylcyclobutane carboxylic acid, 1,2,2,3-tetramethylcyclopentane carboxylic acid, 1,3,3-trimethylcyclohexane carboxylic acid, 1,4-diisopropylcyclohexane carboxylic acid, 2,2-dimethylpropionic acid, 2,2-diethylhexanoic acid, 2-methyl-2-cyclohexylpropionic acid, and 2-methyl-2-ethylbutyric acid.  The compounds may be introduced into the cylinder of the engine with the fuel, separately as a dust or powder or with solvents, or in anti-knock solutions such as tetraethyl lead/alcohol mixtures.  The additives are especially suitable in gasolines which may also contain up to 6.0 ml. of tetraethyl lead per gallon.  The fuels may also contain scavenging agents, dyes, antioxidants, anti-icing agents, inhibitors for rust, corrosion, haze-formation or gum-formation, or anti-pre-ignition agents.  Blending agents such as gasoline-miscible alcohols, glycols, esters, ketones and amides may be added.  The lithium salts may be dissolved directly in the blended gasoline or added as a concentrated solution in the blending agent.  Examples describe the use of the salts in gasolines, iso-octane and fuels of the kerosene or JP-4 jet turbine fuel type.

Abstract: 1,261,503. A method of detaching loose leaves united into books. NETHERLANDS POSTAL & TELECOMMUNICATION SERVICE, DIRECTOR GENERAL OF. 28 Jan., 1970 [28 Jan., 1969], No. 4085/70. Heading B8C. In a process for releasing the leaves of at least one book which has been formed by uniting the leaves by a backing layer L of glue, one, or more, books a-e are gathered together and compressed in a frame, Fig. 6, to form a solid block while a milling cutter 6 cuts out a groove 1 across the leaves and removes the strip of glue L. A pack of books, preferably of punch cards S and initially placed between side boards 4, 5 preferably provided with grooves to let the cutter 6 pass, are placed in the upper compressing compartment of a frame wherein a movable end wall 8 is pressed towards the other end wall 10 and secured, by knobs 44, 45 which slide in slots in a base 11, to maintain the books in a compressed state. The end wall 10, and a side wall 13, are common to the upper and lower compartments of the frame both compartments being open at the front and the lower compartment having a fixed end wall 9, and an inspection opening 17 in the side wall 13. The cutter 6 provides a groove 1 with divergent sides. In a machine for carrying out the process a number of receptacles, filled with books in their upper compartments and containing the original wrappings of the books in their lower compartments, are placed at the input end 34 on a conveyer 25, a sensor 14 and a photo-electric sensor 15, 16 signalling respectively if the books are wrongly placed or if the packing is not in the lower compartment so that defective frame can be removed at a first stopping point 35. A correctly filled frame is held up at stopping points 36, 37 which operate one at a time and, upon arriving at the point.37, causes the operation of a device which senses if the machine is already handling a frame. With no preceding frame in the machine the frame at the point 37 is pushed laterally by a ram 26 so that projections 18, 19 on the frame engage in guides 20, 21 on a movable milling table 24, where spring-loaded rams (32, 33), Fig. 9, (not shown), descend to align the books and a ram 30 holds the books together while the table 24 moves them forward under the cutter 6. The latter removes the glue strip L, while a succeeding frame moves up to the point 39. At the end of the cutting stroke the frame carrying the books is released by the ram 30 and a ram 27 pushes the frame back on to the belt 25. As the belt 25 carries the frame operated upon out of the machine the frame, waiting at the stop 39 moves up to the stop 40 for transfer by a ram 41 into the guides 20, 21 of the milling table 24 where the rams 31 and 30 align, and hold, the books respectively before the table 24 is moved in the opposite direction beneath the cutter 6 and to a position where a ram 42 can move it laterally on to the conveyer 25 which conveys it from the machine.
