Title: Improved process of and apparatus for renovating cards of the type used in accounting machines
IPC: G06K21/08
Filed: 1927-10-27
Abstract: 305,065. Valtat, R. L. A., and Gros, P. Oct. 27, 1927. Statistical apparatus. - Perforated cards used in accounting machines are renovated by pasting thereon sheets of material of accurate predetermined thickness cut to accurate dimensions, and testing the electrical insulating properties of the renovated cards. The applied sheets of material may be of slightly smaller dimensions than the card. One sheet mav be applied to each side of the card and pressed into the card, and the holes in the latter may be previously filled with adhesive pasty material. In the method described a continuous strip of material is applied to a number of cards, and subsequently severed to separate the cards. The cards are placed in a receptacle 1, Fig. 1, and fed therefrom by mechanism 2 of known type which pushes them one by one in abutting relation through a pair of pressure rollers 5. The paper to be pasted on the cards is drawn from a roll 3, passes over a paste roller 4, and then between the rollers 5 where it is applied to the cards. The paste preferably used consists of 20 grams of powdered gum arabic, 5 grams of sugar and 75 grams of boiling water made into a solution, and stirred together with a mixture of 15 grams of starch and 30 grams of cold water, 300 grams of boiling water being added. Two rolls of paper and two sets of pasting rollers may be used to apply paper to both sides of the cards. To close the perforations in the cards, liquid paper paste or similar material may be applied by means of mechanism of known type. This is effected after pasting paper on one side of the cards but before applying paper to the other side. The cards pass from the rollers 5 to a series of heated drying rollers 6, and between pressure rollers 7 which press the applied paper into the body of the cards. The cards are then separated by a cutting mechanism 10 which cuts through the paper. The cutting mechanism is actuated by a spring-pressed roller 9, Fig. 2, which when it drops into the gaps formed by the cut-off corners 12 of two adjacent cards, causes a thin blade to enter between the cards. The apparatus for testing the finished cards comprises a receptacle 12, Fig. 4, with feed mechanism 13, by means of which the cards are passed one by one over a metallic surface 17 and at the same time under a series of metallic brushes 14. The plate 17 is carried by an electrically operated mechanism 16 which causes the plate to tilt downwards when a circuit is completed between the brushes 14 and the plate by the passage of a card with defective insulation, and so reject the card. Cards with satisfactory insulation are pushed on into a box 18.

Title: Transition metal tetrahydridoaluminates
Inventor: JENNINGS JAMES ROBERT
IPC: C07F15/00
Filed: 1968-06-17
Abstract: 1285871 Tetrahydridoaluminates of transition metals IMPERIAL CHEMICAL INDUSTRIES Ltd 16 Sept 1969 [17 June 1968] 28675/68 Heading C2P The invention comprises tetrahydridoaluminates of transition metals of Groups IVa to VIII of the Periodic Table of Elements having at least one anionic ligand of the formula AlH 4  bound to the transition metal and further ligands as required to satisfy the valence and co-ordination requirements of the transition metal. Preferably the further ligands are stabilizing ligands especially those containing Group Vb donor atoms such as phosphorus, co-ordinated to the metal. The preferred products are those containing a transition metal of Group VIII, e.g. Co or Ru. The products are obtained by contacting a transition metal compound containing at least one anionic ligand with an alkali metal aluminium hydride in a dry inert solvent and isolating the transition metal tetrahydridoaluminate product. With certain transition metal compounds it is necessary to have present in the reaction mixture an excess of a stabilizing ligand such as a phosphine. The use of solvents containing acidic hydrogen and those containing alkene, alkyne, nitrile and carbonyl groups should be avoided. The transition metal compound is suitably one of the general formula LxMXy wherein L is a phosphine ligand, M is a transition metal atom, X is an anionic ligand, preferably a halogen, and x and y together satisfy the valence and co-ordination requirements of M. The overall reaction may be expressed by: wherein M<SP>1</SP> is an alkali metal atom. The process is conveniently effected by suspending the reactants in an ether at low temperature, e.g. <SP>_</SP> 78‹ C., and then allowing the mixture to warm up to room temperature, with exclusion of air and moisture. Examples are given for the production of [(C 6 H 5 ) 3 P] 2 Co(AlH 4 ) 3  from LiAlH 4 , triphenyl phospine and bis-(triphenylphosphine) cobalt dichloride and of [(C 6 H 5 ) 3 P]aRu(AlH 4 ) 2  from LiAlH 4 , triphenyl phosphine, and tris- (triphenylphosphine) dichlororuthenium, the reaction being carried out in ether and under nitrogen in each case. The products are useful as catalysts in hydrogenation, polymerization, and olefin isomerization reactions.

Title: Improvements in or relating to liquid fuel injection systems for internal combustion engines
Inventor: MANSFIELD WILFRED PERCIVAL
IPC: F02M45/06
Filed: 1954-10-06
Abstract: 810,456. Fuel injection pumps. BRITISH INTERNAL COMBUSTION ENGINE RESEARCH ASSOCIATION. Sept. 29, 1955 [Oct. 6, 1954], No. 28797/54. Class 102(1). A pilot injection device for a fuel injection system for an I.C. engine comprises a valve housing 5 screwed into the pump body 6, the pump chamber, containing a piston 1 having a control edge 2 co-acting with a spill port 3, is connected by passages 9, 10 to a bore 11 in the valve housing 5. A piston valve 12 is slidable in the bore 11 and is urged to its initial position by a spring 13. A port 14 in the bore 11 communicates by a passage 15 with a connection 16 connected to the low pressure fuel supply. A further port 21 communicates with fuel discharge passage 22. A recess 20 in the valve 12 communicates by a port 19 with the interior of the valve. Initial discharge by the piston 1 forces the valve 12 upwardly until the upper edge closes the upper edge of the port 14 thereafter fuel above the valve 12 is forced through the passage 19 to port 21 and the discharge passage 22 to give a pilot injection which continues until the upper edge of the groove 20 communicates with the chamber 14 thereafter the pressure in the discharge passage 22 falls to that prevailing in the passage 15. The valve 12 continues to rise until its lower edge clears the port 21 thereafter fuel is forced by the piston 1 into the discharge passage 22 and the main injection takes place. When the valve 12 approaches the end of its upward movement it surrounds a cylindrical boss 24 thereby trapping fuel which can only then escape via a restrictor 25. During downward movement of the valve 12 fuel flows back through the restrictor 25 when the port 14 is closed. The passage 15 may be internally connected to the inlet chamber 17. In a modification, Fig. 2 (Prov.) in which the piston 1 is actuated by fluid pressure, pilot injection takes place when the lower edge of groove 20 closes port 21 and continues until the upper edge of groove 20 opens to the chamber 32. Main injection occurs when the valve 12 clears the port 21. The delay period between the cessation of pilot injection and the commencement of main injection is controlled by outflow from above the valve 12 through a restrictor 25 to the connection 16 which is connected to the fuel supply line. This period may be varied by varying the bore of the restrictor 25. Specification 746,280 is referred to.

Abstract: 1,105,319. Friction tests. C.N. ROWE. Aug. 31, 1965 [July 15, 1964], No. 29041/64. Heading G1S. A self-contained portable unit for measuring the coefficient of friction between a standard surface and another surface comprises a housing 9, 10, 11, a carriage and a drive for moving it at a steady speed within the housing, a shoe 52 on which the standard is provided and which is connected to the carriage through a spring device 47, 49 and an indicator 34 mounted on the carriage and indicates the stress in the spring device, the arrangement being such that in use the stress in the spring device provides a corresponding tension tending to pull the shoe along the other surface and as the carriage moves the stress and tension increase until the friction between the standard and other surface is just overcome whereupon the indicator registers at the moment of movement a value dependent upon the limiting friction between the two surfaces. The carriage slides on guide rods 14, its movement being limited by rubber headed stops 19, 20 engaging side flanges 16, 17. The carriage is urged to move to the right by a coiled spring 21. The movement of the carriage is dampened by a dashpot cylinder 27. The live pointer 34, with a slave pointer 35 is mounted on a spindle 39 having a drum 42 rigidly fixed thereto. The measuring operation is started by pressing control knob 58 which through a lever system releases the carriage for movement by spring 21. The shoe 52 will not move immediately because of the frictional force and hence the drum 42 is rotated by the force in rod 47 building up stress in spring device 45, 49, carrying the pointers 34, 35 over the scale. When the frictional force is just overcome the shoe will suddenly move relieving the stress in the spring device so that the drum and live pointer 34 rotate back to zero position. The carriage will continue to move and the cycle will be repeated until the carriage reaches abutment 20. The slave pointer 35 will record the maximum frictional force and the scale may be calibrated directly in coefficients of friction.
