Title: Improvements in or relating to wire-tying machines
IPC: B65B13/28
Filed: 1944-09-14
Abstract: Relates to an automatic wire-tying machine of the type in which a wire is looped around an article to be bound, drawn taut under tension, twisted to form a tie, and cut beyond the ends of the tie to remove any surplus end portion and disconnect the tied portion from the supply.  According to the invention, the mechanism includes means for tensioning the wire about the article, a lever, a spring in engagement with one end of the lever, a travelling wire gripper, means for moving the gripper into a position wherein it becomes operatively connected with the other end of the lever whereby the tension put on the gripper by the action of the tensioning means on the wire is opposed by the spring, and means actuated by the oscillation of the lever for controlling said tensioning means to stop the pull of the wire against the lever. When the tension in the wire reaches a pre-determined amount, which is governed by the capacity of the spring to resist tension, the lever oscillates under the pull of the wire to a sufficient extent to open an electric switch and, thereby, stop the motor which is actuating the tensioning means.  The machine to which the invention is applied is identical with that disclosed in Specifications 615,617 and 615,657.

Abstract: 1374427 Measuring water content NEWPORT INSTRUMENTS Ltd 8 March 1972 [5 May 1971] 13226/71 Headings G1N and G1S The water content of a material containing organic hydrogen is determined by mixing a sample of the material with a quantity of heavy water so as to allow hydrogen-dueterium exchange to occur, separating the mixture into an aqueous phase and a non-aqueous phase and determining the hydrogen content of the aqueous phase. The hydrogen content may be determined by infrared spectroscopy, mass spectrometry or by N.M.R. The material may be a fat, and the heavy water may be acidified with hydrochloric acid to a pH of 1 to 2 to suppress ionization of fatty acids in the fat. If N.M.R. is used to determine the hydrogen, a paramagnetic salt such as Cu (NO 3 ) 2 .3H 2 O or a soluble salt of the "d" block transition metals (e.g. manganese, copper, iron, cobalt or nickel) is added to the heavy water to reduce the proton relaxation time. The hydrogen content of the heavy water is preferably determined both before and after contact with the material, and the increase in hydrogen content is a measure of the water content and may be compared with a calibration curve. The material may be margarine, butter, mayonnaise, groundnut cake, milk powder or animal feedstuffs.

Title: Improvements in or relating to the manufacture of solid chlorinated rubber products
IPC: C08C19/12
Filed: 1933-05-10
Abstract: A solution of chlorinated rubber is heated at any desired pressure, and the pressure is suddenly reduced to below the vapour pressure of the heated solution, so that a substantial proportion of the solvent is flashed off: the remainder is evaporated by simultaneously supplying heat from an auxiliary fluid heated to a temperature higher than the condensation temperature of the solvent.  The auxiliary fluid may be a volatile liquid or a non-solvent for chlorinated rubber such as water, or it may be a gas.  Stabilizers, plasticizers, colouring matters &c. may be added to the initial solutions. According to an example, a 10 per cent solution of chlorinated rubber in carbon tetrachloride is agitated with its own weight of water and heated in an autoclave to 120 DEG  C.  The hot mixture is blown by its own pressure through a nozzle into a chamber heated to 80 DEG  C. The chlorinated rubber collects in the bottom of the chamber with some water, and is dried in a current of warm air.

Title: Impact tool
IPC: B25D11/12
Filed: 1973-03-21
Abstract: 1389803 Percussive tools MATSUO LABORATORY CO Ltd 21 March 1973 [3 April 1972] 13635/73 Heading B4C A pneumatic impact tool comprises a crankoperated air pump piston 3 operating in a cylinder 4 which communicates with the tool cylinder 2 through side openings 6 and through an upper tube 5, the tool cylinder being provided with a one-way exhaust port 12 which communicates with the upper tube through a relief valve 11 when a male portion 10 on the hammer piston 1 closes the aperture 2<SP>1</SP> in the tool cylinder head. To start the hammer piston the chisel 9 is brought into contact with the material to be crushed to push the piston upwards to open the space 2b below the hammer piston with the space 4b below the pump piston. The downward movement of the pump piston reduces the pressure in the upper spaces 2a, 4a and increases the pressure in the lower spaces 2b, 4b to lift the hammer piston. The hammer piston is cushioned when the plug 10 enters the aperture 2<SP>1</SP>, the air trapped in the space 2a being let through into the tube 5 when the pressure reaches that set by the non-return valve 11 in the exhaust port 12. The hammer piston remains in its upper position until the pump piston has returned to its upper position where maximum pressure exists in the tube 5 and minimum pressure exists in the lower spaces 2b, 4b. The maximum pressure is first applied to the area of the plug and then to the whole area of the hammer piston as the hammer piston starts its downward movement. Upon striking the chisel 9, the hammer piston rebounds so that the side openings 6 are covered at the upper edge and the still descending pump piston applies a negative pressure in the upper spaces 2a, 4a and a positive pressure in the lower spaces 2b, 4b to cause the hammer piston to rise as described earlier. The side openings 6 may be divided into two side openings, Fig. 4 (not shown).
