Title: Improvements in or relating to apparatus for indicating the level of liquids
IPC: G01F23/24
Filed: 1919-08-02
Abstract: 139,103. Barclay, S. F. Aug. 2, 1919. Order-type apparatus.-Liquid levels, especially in fuel tanks of automobiles and oil and water tanks, are indicated by comparing the resistances of wires partly and wholly immersed in, and cooled by, the liquid, with that of a wire not in contact with the liquid. The apparatus compensates for variations in the temperature conditions, in the voltage of the battery, and in the characteristic of the galvanometer. In the form shown in Fig. 3, two arms of a wheatstone bridge are formed by equal constant resistances 4, 5. The third arm comprises a wire 2 located in the liquid-container 18 and protected by a tube 9 containing air. The fourth arm comprises, alternatively, a. wire 3 which is partly immersed according to the level of the liquid, or a wire 1 which is immersed wholly or to a fixed extent. These wires can be connected in circuit by a two-way switch 8, and are coated with insulation if necessary. The galvanometer 7 is calibrated so that it reads directly in levels or volumes when the wire 3 is in circuit. The liquid level is given by the ratio of the readings obtained with the wires 3 and 1 respectively, or the rheostat 10 may he adjusted until a standard reading is given with the wire 1 in circuit. Permanent minor adjustments are made by means of the resistances 12, 13, 14. In a modification, two bridges are arranged in series or parallel, one containing the wire 1 and the other the wire 3. The former bridge may either be adjusted as described above to give a standard galvanometer reading, or may have its galvanometer graduated in terms of the corrections which must be applied to the galvanometer of the second bridge, when temperature conditions differ from those in which the latter was calibrated. The wire 1 may alternatively be surrounded by any suitable gas, solid, or liquid.

Title: Improvements in and relating to can openers
IPC: B67B7/46
Filed: 1952-07-30
Abstract: 712,309. Can-openers. SWING - A - WAY MANUFACTURING CO. July 30, 1952 [May 19, 1952], No. 19283/52. Class 66 A can-opener has a base plate 32 adapted to be secured to a wall and which has journalled therein a shaft 74 carrying a serrated drive wheel 70 and a pinion 76 on one side of the base plate 32 and a crank handle 42 on the other side. A cutting wheel 90 and associated pinion 96 are mounted at an angle on a bulge 80 in a carrier plate 78 which is slidably secured to the base plate 32 by means of a rivet 102 and a stud 174. The rivet and stud pass through the base plate 32 and connect carrier 78 to an actuated plate 104. The rivet 102 passes through a slightly inclined slot 64 in the base plate 32 and the stud 174 passes through the lower part of a figureof-eight shaped link which moves in an opening 52 specially shaped to give an over-centre toggle action to the link. The crank handle 42 comprises a drum-like part 118 having inside it a boss 128 carrying a rigid cam 138 and a pivoted spring-loaded dog 156 (see Fig. 10). An actuator pin 114, fixed on the actuated plate 104, lies within the part 118 and co-operates with the cam 138 and dog 156. The can-opener mechanism is in its inoperative position in each. of the Figures shown except Fig. 10, wherein the actuator pin 114 is shown in the operative position. To open a can C (Fig. 7) the top bead thereof is placed on the serrated edge of the drive wheel 70 with its side wall W against a flange 68. Handle 42 is then rotated anticlockwise as seen in Figs. 1, 10 and 11 and the cam 138 (Fig. 11) forces the pin 114 to the left until it reaches'the position shown in Fig. 10 (further rotation of the handle having caused the dog 156 to spring past the pin 114). In moving to the left, pin 114 forces the actuated plate 104 and hence the carrier plate 78 to move also, and cutter wheel 90 is carried down to pierce the top of can C (Fig. 8, not shown). This action also engages pinion 96 with pinion 76. Continued rotation of the handle now rotates the can C and severs the top T therefrom, whereupon the handle is given a short backwards rotation to cause dog 156 to engage pin 114 and force it back into the inoperative position as indicated in Fig. 11. This lifts the cutter wheel 90 and frees the bead of the can C which may then be removed. A small block 148 (Fig. 7) of neoprene is mounted in the boss 128 to buffer the heel of dog 156 and prevent clicking as the dog snaps off pin 114 during each revolution of handle 42.

[Class 55 (i)] In the production of oils by low temperature distillation of coal, lignite, oil shale, petroliferous sandstone, &c. in a distillation chamber through which the material passes vertically downwards, by means of hot gases or superheated steam flowing: horizontally therethrough in a closed circuit, followed by combustion of the distilled material by means of oxygen-containing gas, the hot residue is utilized to preheat the hot gases or steam used in the distillation chamber. Superimposed chambers of a retort comprise a preheating or drying chamber A, a distilling chamber B, a combustion chamber C and a residue cooling chamber D and are utilized in combination with a condenser L and a heat exchanger E. The distilling medium is superheated by passage through the hot residue in D and then through the heat exchanger E before entering the distilling chamber B from which the gases and volatile products pass into the condenser L. Oils are recovered in the latter and the non-condensible gas or lowpressure steam, which may be compressed by a compressor M, is returned to the cycle. Hot water separated in the condenser may be utilized for the production of steam required in the process. Oxygen-containing gas is supplied to the combustion chamber C through a supply pipe 7, part of the issuing gases being used in the heat exchanger and part, after utilization in an external apparatus, such as a boiler K, being used in the preheating chamber A. The flow of gases through the chambers A and D may be horizontal or vertical.

Title: Process for the isomerization of saturated hydrocarbons
IPC: C07C9/00
Filed: 1957-06-25
Abstract: In the isomerization of an isomerizable saturated hydrocarbon fraction of average molecular weight not above 72 the fraction is passed in admixture with a recycle, produced as described below, to a first fractionating column from which is obtained overhead a product isoparaffin fraction free of n-paraffins which are obtained as bottoms free of isoparaffins, a minor proportion of these bottoms is fractionated in a second fractionating column, removing as bottoms a fraction of average molecular weight greater than that of the feed and overhead a fraction of molecular weight not greater than that of the feed which overhead is mixed with the major proportion of the bottoms from the first fractionating column and isomerized in contact with a platinum-containing catalyst and the effluent from the isomerization forms the recycle mixed with the feed to the first fractionating column.  The feed may be a butane fraction containing n-butane in which case isobutane is removed as product from the first column and C5 hydrocarbons are removed as bottoms from the second column, or a pentane fraction containing n-pentane when isopentane is obtained as product and C6 hydrocarbons removed from the second column.  The isoparaffins may be used as such in gasolines or used for alkylation with propylene, butylenes or amylenes to yield higher molecular weight isoparaffins.  The catalyst in the isomerization zone may contain 0.01 to 1.0 per cent platinum with a larger amount of combined halogen, e.g. 0.1 to 3 per cent of fluorine and chlorine, supported preferably on alumina or silica-alumina, silica-zirconia or silica-alumina-zirconia.  The isomerization is preferably performed in the presence of hydrogen at 3.4-68 atmospheres, 371-510 DEG  C., an LHSU of 0.5 to 5 with 0.5 to 5 mols. of hydrogen per mol. of hydrocarbon.
