Title: Connections for plates of cells of storage batteries and method for making same
IPC: H01M50/529
Filed: 1972-06-26
Abstract: 1401361 Iritercell connections for storage batteries FABRICA ACCUMULATORI URANIO SpA 26 June 1972 29829/72 Heading H1B An electrical connection is formed between two terminals 5, 6, attached to respective plates 4, 7 of different cells in a storage battery, through a planar wall 3 of thermoplastics material by placing planar surfaces of each terminal in contact with opposite sides of the wall 3 and connecting the terminals by a conductive member, e.g. a pin 13, extending through an aperture 12 in the wall 3, the size of the aperture 12 being such as to form an annular space around the pin 13, and injecting into this annular space a fluid thermoplastics material, this material being the same material as the wall 3, at such a temperature as to soften a portion of the wall and on cooling to form therewith a seal for the connection. As shown, each terminal may be shaped to provide further annular spaces 9, 11 around the pin 13, which is separate from the terminals and which fits snugly into bores 8, 10 in the terminals, where it is electrically welded thereto. A bore 15 in one of the terminals provides a communicating passage through which the thermoplastics material, e.g. polyethylene, polypropylene or copolymers thereof, is injected. Alternatively, Figs. 3 and 4 (not shown) the pin is formed in two halves, each half being integral with a respective terminal and the two halves welded together. The thermoplastics material may be hot when injected into the chambers.

Filed: 1966-07-05
Abstract: <PICT:1116316/C6-C7/1> In a process and machine for ornamenting and softening leather, a piece of leather is heated by a heater, and then pressed by an embossing tool whilst relative turning movement, e.g. of the order of 90 DEG , is effected between the tool and the piece of leather. The tool may be applied, in succession, to different parts of the piece of leather.  Using the machine shown in Fig. 1, the piece of leather is placed over a central hole in a table 2, and heated by a heater 4 positioned in the hole and fixed to the pedestal 1. The heater is preferably controlled by a thermostat, which can be adjusted or set, by a manual control 5, e.g. to heat the leather slowly to a temperature between 300 and 375 DEG C.  The shaft 6 and the embossing tool 7 carried thereon are reciprocated up and down, and turned each time the tool 7 is in its lowest position pressing the leather, supported on the heater.  The table 2 is also reciprocated up and down, e.g. through a distance of 1/4 inch, at a somewhat faster rate of oscillation than the tool 7.

Title: Improvements in or relating to the testing of fuel elements for nuclear reactors
Inventor: NAIRN JOHN SYME
IPC: G21C17/07
Filed: 1962-08-03
Abstract: 974, 314. Nuclear fuel elements. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. July 19, 1963 [Aug. 3, 1962], No. 30077/62. Heading G6C. A method of testing an irradiated nuclear fuel rod consisting or uranium dioxide fuel enclosed in a protective sheath to determine whether the rod is leaking, comprises heating the rod so that the crystal structure of the uranium dioxide in a leaking sheath will be changed and testing the surrounding atmosphere for the presence of fission products released from the uranium dioxide as a result of the change in crystal structure. As shown, a fuel element 1 comprising two clusters 2 of fuel rods 3 is supported in a furnace 20 having inlet and outlet pipes 6 and 7 respectively passing through shielding 8, the outlet pipe 7 being connected through a valve 10 to a beta counting cell 11 and a charcoal trap 12. The trap 12 has an outlet pipe 13 fitted with a valve 14. Lead shielding 15 surrounds the cell 11 and trap 12. A beta-sensitive crystal assembly 16 is associated with the cell 11 and a gamma-ray sensitive crystal assembly 17 with the trap 12, The furnace temperature is raised to between 300 and 400C. and a stream of air passed over the fuel element 1, the air entering through an iodine filter 9a and pipe 6 and leaving through an iodine filter 9b and pipe 7. The trap 12 is immersed in liquid oxygen -183C. and gamma counting is continuous during the passage of the air stream. The beta-emission from the fission products collected in the trap 12, however, is counted at the end of the test when the valves 10 and 14 are closed and the liquid oxygen bath replaced by a furnace at 100 to 200C. The collected fission products are then boiled off and fill the space between the valves 10 and 14, including the cell 11. The beta activity in the cell 11 is then determined. When the fuel element is heated in an air stream as above, the crystal structure in a leaking fuel rod is changed by oxidation of the uranium dioxide to a higher oxide.

Title: Improvements in the separation of weak acids from gases
IPC: C01B32/50
Filed: 1933-10-30
Abstract: Weak gaseous acids, such as carbon dioxide or hydrogen sulphide, are removed from gases containing the same by scrubbing with a liquid containing an alkali metal or alkaline earth metal salt of an amino carboxylic or aminosulphonic acid capable of forming readily water-soluble alkali metal or alkaline earth metal salts and having the constitution <FORM:0428059/III/1> in which R1 and R2 are alkyl, hydroxyalkyl, aralkyl or aryl groups.  R3 is an organic radicle combined with a carboxylic or sulphonic acid radicle and R2 may also be hydrogen or an organic radicle bearing a second acid radicle, the liquids being regenerated by heating whereby the absorbed weak gaseous acids are driven out.  Examples of suitable acids are:--N-monohydroxyethyl glycocoll N-dihydroxyethyl - glycocoll, N-mono-ethyl glycocoll, N - diethyl glycocoll, N - monoethyl aminosuccinic acid, N - monohydroxyethyl alanine, N - monomethyltaurine, N - monoethyltaurine, hydroxyethyl - imino - dipropionic acid, N - monopropanediolaminoacetic acid, methyl - imino - ditaurine and dimethyl-N-anthranilic acid.  According to examples aqueous solutions of the sodium salts are employed and may be regenerated by heating at 130 DEG  C., or treatment with superheated steam.  The removal of carbon dioxide and hydrogen sulphide from coke oven gas is described.  Specifications 391,780 and 391,786 are referred to.

Abstract: Sponge rubber is made by frothing latex without the use of a foam stabilizing agent, and coagulating.  Preferably a concentrated latex obtained by centrifuging latex to which only an alkali preservative has been added is used.  Sulphur and an accelerator may be added before heating or whipping the latex, or during an internal in the frothing, the zinc oxide or other activator being added thereafter.

Abstract: 636,080. Fuel injectors. KAMMER ENGINES, Ltd., and KAMMER, G. S. Nov. 18, 1947, No. 30632. [Class 7 (iii)] A passage 27 leading to the main fuel delivery valve 29 is controlled by a spring pressed plunger 2 which is raised by the rise in pressure due to the excess fuel supplied to the pilot delivery valve 28. The space 3 is filled with fuel the pressure of which during injection is limited by a non-return valve 8 in an escape passage 17, and after injection is relieved through a ballvalve 19. At the start of injection valve 19 closes and fuel flows through passage 21 to open the pilot valve 30 controlling the open pilot nozzle 39. The pressure in space 23 builds up, acting on plunger 2 to increase the pressure in space 3 until fuel escapes through the valve 8 and plunger 2 moves to open the passage 27. The passage 31 is smaller than passage 30 so that the valve 29, controlling the open main injection nozzle 40, does not open until a still higher pressure builds up in space 23. At the end of the pump stroke, valve 19 opens and the plunger 2 moves down and displaces fuel from space 23 through, the passage 21 to the space 3.
