Title: Improvements in methods and apparatus for emptying containers having flexible walls and containing viscous liquids or pasty substances
IPC: B65D83/00
Filed: 1936-12-21
Abstract: 477,068. Syringes. TECALEMIT, Ltd. Dec. 21, 1936, Nos. 35110 and 35111. Convention dates, Dec. 21, 1935 and Nov. 10, 1936. [Class 102 (ii)] [Also in Group XVII] Collapsable paper or like containers for lubricant &c. are emptied by being enclosed in a rigid chamber having a lining comprising a flexible pocket or bag of flexible leakproof material such as indiarubber, compressed air being introduced into the closed space afforded between the chamber and the lining to bring about the deformation of the pocket or bag, which thus causes the crushing and collapsing of the enclosed container. In the construction shown, a container 10 is enclosed in a chamber 11 provided with a rubber lining bag 14, the upper edge of which is held between the mount ring 13 and a screwed-on washer 15, the rim 10a of the container being gripped between the washer and the hinged cover 12 so as to afford a tight joint, and the cover having a discharge outlet 24 disposed in register with an opening 26 in the end of the container. Compressed air admitted by a union 17 and passage 18 to the space P between the chamber and the lining causes the container to be collapsed as indicated in chain lines. The walls of the rubber bag may be of uniform thickness, but in the construction shown they diminish in thickness from B to A, thereafter increasing to afford a thickened base portion G, such construction being found to facilitate the uniform crushing of the container. In a modification of the construction, the upper end of the rubber bag may be formed into a beaded edge 14b, Fig. 4, between which and the cover the beaded edge of the container is clamped. In a further modified construction, the mouth of the rubber bag is attached to a metal reinforcing ring 38 of angled form to render it non-deformable, the crushing action then taking place in the manner indicated in Fig. 6.

Abstract: 881,256. Lightning arresters. WESTING- HOUSE ELECTRIC CORPORATION. Oct. 20, 1959 [Oct. 30, 1958], No. 3546/59. Class 38 (4). A lightning arrester comprises two discshaped separators 10, 12 of insulating material, preferably ceramic, reversibly placed face to face, each having integrally formed radially extending arc splitters 14 engaging with recesses 18 formed on a semi-circular raised portion 16. At the ends of each splitter 14 and recess 18 is a semi-circular depression 20 in which metallic balls 31 forming splitter tips are positioned. A raised portion 26 is received in a recess 24 of the other separator. A substantially triangularshaped opening 22 receives one electrode which is formed on a disc-shaped sheet (preferably brass) which encloses a permanent magnet 34 which may be of ceramic magnetic material such as barium ferrite. Flanges 32 between electrodes may be secured by means such as welding or brazing. When the arc is formed between adjacent electrodes the permanent magnetic field drives it into the splitters and recesses 14, 18 thus cooling and lengthening it. The use of ceramic material for the splitters is stated to give improved performance above that of metal splitters and the use of metal arc tips 31 is stated to improve the performance still further. Specification 814,509 is referred to.

Title: Improvements in or relating to brakes for motor vehicles
IPC: B60T17/08
Filed: 1930-11-25
Abstract: 373,969. Vehicle brakes. BADERTSCHER VAKUUMBREMSE AKT.-GES., 14, Falkenstrasse, Zurich, Switzerland. Nov. 25, 1930, No. 35475. Convention date, Nov. 26, 1929. Void [Published under Sect. 91 of the Acts]. [Class 103 (i).] Fluid pressure; compensating for wear. -Relates to vehicle brakes in which the brake shoes are brought into contact with the brake drum by a piston actuated by the suction of the engine when the ac celerating pedal re turns to the off position, the effective pressure being applied by a pedal acting upon a brake rod which has been displaced by the piston and consists in the provision of means for adjusting the position of the brake rod to compensate for wear of the shoes so that the movement of the pedal in applying the brakes when the suction device fails remains the same. The piston (not shown) working in the cylinder 37 is connected to the brakes by the link 43 and lever 52. The pin 42 on the lever 52 passes through the slotted end 44 of a rod 45 having a threaded part 45<1>, the threads having one face inclined to the axis of the rod and the other face perpendicular as shown. A ring 46 in a number of parts surrounded by a spring 47 engages the rod 45 and normally abuts on a stop member 48 adjustably screwed into the part 50 secured to the brake cylinder thus determining the normal position of the piston and the brake rods. If when the brake is applied the piston with the rod 45 by reason of wear of the brake shoes moves an excessive amount, the ring 46 comes against a stop 51 and slips over a tooth of the rod 45 so that the parts do not return to the original position.

Patent GB-962866-A (GB)
Title: Process of producing alkylene imines
IPC: C07D203/08
Filed: 1962-09-18
Abstract: Alkylene imines are produced by adding a solution of an amino alkanol sulphuric acid ester in an aqueous alkali metal hydroxide solution to the top of a reaction zone counter currently to water vapour ascending, thus heating the solutions and causing them to react, the length of the reaction zone being sufficient to enable the reactants to react substantially completely to form an alkylene imine which is converted to vapour form, the vapours of water and alkylene imine being removed from the top of the reaction zone and an aqueous solution of alkylene imine being recovered from these vapours.  The residence time in the reactor may be shortened considerably by carrying out the process under superatmospheric pressure. The process is preferably carried out continuously and in this case it is necessary that the concentration of the alkali metal sulphate formed should be kept below saturation at the temperature in the apparatus. Examples are given of the preparation of (a) ethylene imine from animo ethanol sulphuric acid ester; (b) 2-methyl ethylene imine from the sulphuric acid ester of 2-methylaminoethanol; (c) 2,2-dimethyl ethylene imine from the sulphuric acid ester of 2,2-dimethyl-amino ethanol and (d) N-ethyl ethylene imine, from N-ethyl amino ethanol sulphuric acid ester.
