Title: Improvements in electric cells
IPC: H01M2/38
Filed: 1959-10-02
Abstract: 877,896. Batteries; electrolytic cells. TUDOR A.B. Oct. 2, 1959 [Oct. 31, 1968], No. 33522/59. Classes 41 and 53. A battery cell is provided internally with an open-ended electrolytic cell 1 immersed in the battery electrolyte. When current is passed between the electrodes 2, 3 of the cell the gases evolved pass up the tube 1 which terminates below the level 9 of the electrolyte. In Fig. 1 the tube 1 is provided with a constriction 10 to enable large gas bubbles to be formed which fill the tube so that when they loosen and rise they lift the electrolyte above them and thus stir and cause circulation of the electrolyte. The same result may be obtained by making the tube 1 of a sufficiently small bore, or by forming its upper part of reduced diameter as shown in Fig. 5. The current for the cell may be obtained from the battery in which it is enclosed or from an outside source. A switch may be provided to disconnect the electrodes 2, 3 when the battery is being charged. Several electrolytic cells may be mounted in the battery as shown, for example in Fig. 3 in which cells 1 are mounted between parts of the positive electrodes 10.

Title: An improved method of and apparatus for testing the balance of rotatable bodies
IPC: G01M1/22
Filed: 1927-12-20
Abstract: 299,636. Lundgren, J. Dec. 20, 1927. Testing balance of rotary apparatus. - Comprises a method which consists in supporting the body to be tested, rotating the body, limiting in one direction the movement of the body under the unbalanced forces and permitting the body to move freely in the opposite direction so as to influence an electrical angle indicating device whereby the angular position of the unbalance can be observed. A foundation plate 1 provided with a raised portion 2 carrying a motor 3 is slotted to receive the securing bolts of base plates 7 of the specimen supports which are longitudinally adjustable on the plate 1. Each base plate is provided with an upwardly extending portion 9 to which is connected a bracket 10 bifurcated to receive a spring holder 12 pivoted to it. The holder has secured to it a spring 15 carrying a V-bearing 17. Each holder is threaded to receive a screw 20 provided with an enlarged and graduated collar 21 and a knurled handle 23. A contact carrying plate 25 is also fixed to the part 9 of the base to the upper end of which is secured a bar of insulating material 26 carrying a contact screw 30 adapted to co-operate with a contact 31 secured to the bearing. Each base plate 7 has one or more studs 34 connected at the upper end to a cross bar 35 provided with an adjustable screw stop 36. The motor 3 drives the specimen through a universal coupling 38, flexible rod 39 and coupling 40. The dial hand 51 is driven from the motor shaft through gears 41, shaft 43 and gears 46, 47 and moves over a dial 53 of conducting material. The rotor to be balanced is mounted in the bearings 17 and coupled to the motor. The masses 20 are adjusted to their neutral positions and the motor started. The vibration due to unbalance causes one or both contacts 31 to engage contacts 30 so that on pressing one or both of two pushes the current through an induction coil is broken and a spark passes between the hand and the dial showing the angle of unbalance. The angle is determined for one axial plane of balance by moving the screw 36 to prevent oscillation at the other end, and the mass 20 is adjusted until no spark passes. This gives the amount of unbalance. The same operation is now done for the second balancing plane. Any number of balancing planes may be chosen.

Patent GB-655364-A (GB)
Title: Improvements relating to fractional distillation
IPC: B01D3/14
Filed: 1947-12-29
Abstract: In fractional distillation using a thermally-insulated, non-packed column, the input of heat to the still is regulated so that the average velocity of the vapour in the column lies between 2D/a and 20D/a, where D is the diffusion constant of the vapour and a is half the minimum internal cross-sectional dimension of the column.  Air should preferably be excluded from the upper part of the column where the return-flow of condensate begins.  This method utilizes very low-vapour-velocities which increase the number of theoretical plates obtainable from a given column.  The column may be a jacketed cylindrical tube with or without a cylindrical core, or a bubble-cap column.  In the latter case a is half the diameter of the funnels inside the caps.  The jacket of the column may be evacuated or may contain a boiling liquid.  A mathematical formula for the calculation of D for a binary mixture, is given in the Specification.  In an example, a mixture of benzol and carbon tetrachloride was fractionated at atmospheric pressure using a tube 30 cm. long and 0.3 cm. radius, the "heads" being withdrawn through a heated tube leading to a condensate trap having a cooled surface maintained only a little below the boiling temperature of the mixture.  The supply of heat was adjusted to 9 X 10-3 cal./sec. giving an average vapour-velocity of 0.13 cm./sec.  The number of theoretical plates obtained was 100.

Title: Manufacture and application of a plasticising agent for cellulose derivatives
IPC: C08K5/103
Filed: 1935-12-17
Abstract: Glycerol lactate triacetate which is a plastifier for cellulose derivatives is made by acetylating all the hydroxy groups of glycerol mono-lactate which may be prepared as described in Specification 456,525.  The acetylation may be effected with acetic anhydride or acetic acid which may be relatively dilute, such as 90 per cent strength.  When the acid is used it is preferable to add a solvent such as benzene to entrain the water liberated.  In examples: (1) glycerol monolactate is acetylated with glacial acetic acid in presence of sulphuric acid and benzene; the benzene from the distillate is separated and returned to the reaction vessel until the required quantity of water is removed; (2) the acetylation is affected with acetic anhydride in presence of sulphuric acid. Glycerol lactate triacetate is a plasticizer for cellulose derivatives and may be used with cellulose nitrate or acetate, with or without a natural or synthetic resin for lacquers or coating-compositions in quantity from 25--150 per cent of the cellulose ester; for cellulose acetate moulding-powders the quantity may be 40 per cent; for cellulose acetate triacetate or nitrate for making sheets, films or rods and for cellulose acetate or triacetate for spinning artificial fibres by wet or dry-spinning processes; and in the manufacture of laminated glass having an intermediate sheet of cellulose acetate, triacetate or nitrate, the glycerol lactate triacetate may be an ingredient of the sheet, or may be used as a bath to treat the sheet to render it adhesive, and it may also be used as an ingredient in adhesive compositions containing cellulose acetate or nitrate, a synthetic resin and a solvent such as acetone for use in the production of laminated glass.
