Title: Improvements in Matrix Holders for use in Casting Printing Slugs and the like.
Inventor: PRINGLE JAMES BROWN
IPC: B41B5/02
Filed: 1918-09-03
Abstract: 125,007. Pringle, J. B. Sept. 3, 1918. Matrices for type-bar-making machines. A holder for matrix members such as are used in casting rules, borders, &c. is formed of two blocks which can receive between themselves the matrix members and are provided with tightening- means; special matrix members, described below, may be employed. As shown in Figs. 1 and 4, the blocks 2, 3 are formed with shoulders 8<a>, and the block 2 is provided with bolts 5 which pass through the block 3 and carry tightening- screws 7. The matrix members 4 consist of strips formed with slots 14 which engage the bolts 5 to hold the strips against longitudinal movement and to position the casting-faces 15 of the strips with respect to the mould. The strips may also be formed with holes for engaging a bolt 18 which is screwed into the block 2. A composite design may be produced by employing a number of matrix strips having different designs on the faces 15. Spacer or filler-strips having their faces Hush with the faces 8 of the blocks are provided. In the holder shown in Fig. 5, a shallow block 2 is employed, instead of the block 2 shown in Figs. 1 and 4, in order to provide a greater space between the blocks; further, the blocks are adapted to receive matrices such as the long strip 26<a> or bevel-edged strips. Short bevelled strips each having a letter matrix may also be provided. The strip 26<a> is received by the flanged edges 26 of strips 25 which are spaced apart by blocks 24, 27. The bevel-edged matrices may engage grooves 20, 21 in the blocks 2, 3, or may engage grooves 29 in strips 28, Fig. 9. The spacing-blocks and the strips are formed with slots and holes for engaging the bolts that connect the blocks 2, 3. The matrix-strips may be made of cardboard, papier mÔchÚ, &c.

Abstract: 438,058. Driving magnetos. HODGKINS, W. A., 9, Cauldwell Drive, Nottingham Road, Mansfield, Nottinghamshire. May 12, 1934, No. 14357. [Class 35] [See also Groups XI and XXXVII] A device for igniting a plurality of burners comprises a magneto and a distributer operated by a single foot or hand operated means. As shown, the spindle 17 of the distributer is connected by gearing 26, 27 with the spindle 18 of the magneto 3 and is rotated in one direction only by means of a spring-pressed pawl 25 on the gear 26 co-operating with a loose pinion 21 operated by a toothed quadrant 22 connected with a spring-controlled pedal 23. The primary winding of the magneto is electrically connected with a contact breaker 6, operated by a cam 19 on the spindle 18, and the induced current is conveyed from the secondary winding by a wiping contact 7<a> to a ring 7 having a wiping contact 16 for engaging successively a series of contacts associated with terminals 9 connected to electrodes 12 forming spark gaps with the burners 13. The pedal 23 may be coupled to the quadrant 22 by a spring 33 to provide a resilient cushion effect when the pedal is depressed. In a modification, the spindle 17 is rotated directly by means of a rubber or like rimmed or tyred wheel fixed to an extension of the spindle.

Abstract: 967,209. Operating doors of skips. A.C.E. MACHINERY Ltd. March 27, 1963 [April 13, 1962], No. 14385/62. Heading B8H. A skip for a guided skip hoist is provided with a bottom discharge opening 2, normally closed by a door 3 mounted on pivoted arms 4, and a shoot 6 pivoted about an axis 7 and connected by links 10 to arms 11 secured to the arms 4. The shoot is held in an inoperative position by a spring-loaded latch 8 acting on a pin 9. When the latch is released by engagement with an abutment at the top of the hoist, the shoot falls under gravity to a position determined by a chain 14 and thereby causes the door 3 to be raised. Lost motion is provided between the door and the shoot by pin-and-slot connections between the shoot and the links 10. A scraper blade 15, carried by arms 16 pivoted on the arms 4, strikes the shoot as the shoot approaches its upper position and scrapes the shoot towards its free end.

Title: Improvements in and relating to a method of and means for generating steam
IPC: F22B1/28
Filed: 1922-05-22
Abstract: 196,499. Cohen, H. E. May 22, 1922. Generating by electricity.-Steam is generated by passing an electric current through one or more open-ended carbon tubes or the like supported by a float in the boiler water in a partially immersed position. The vertical carbon tubes 17, Fig. 1, are connected in series by end connectors 18 and are secured tightly against a rubber covering on the sides of a float 23 by a band 26 of insulating material. A switch 37, Fig. 2, in the current supply lines 39, 41 is automatically opened when the boiler water falls below a certain level. When the water falls, the float rests upon a collar 66 on a rod 62 inside the tubular guide member 29 and moves the rod downwards, thus opening a switch 48 in a branch circuit containing an electromagnet 44 acting on the locking arm 49 of the switch 37. The switch is opened by a spring 42 when the locking arm is released.

Title: A method of influencing the speed of enzymatic reactions
IPC: C12N9/00
Filed: 1928-05-18
Abstract: 291,443. Nord, F. F. June 3, 1927, [Convention date]. Tobacco.-Enzymatic reactions, e.g., in the fermentation of tobacco leaves, are facilitated by treating the enzyme with an unsaturated hydrocarbon, e.g. acetylene, ethylene, propylene, butylene, amylene or mixtures of two or more of them. The hydrocarbons have a protective effect by forming an adsorption layer on the surface of the colloidally dissolved enzyme and enhance the permeability of cells. In an example, fermentation of tobacco leaves is accelerated by treatment with ethylene, the increased activity of the catalase present being shown by observing its action in decomposing hydrogen peroxide. The Specification as open to inspection under Sect. 91 (3) (a) refers also to the use of nitrous oxide as a protective agent. The subject-matter does not appear in the Specification as accepted.

Patent GB-814472-A (GB)
Title: Method of catalyst preparation
IPC: B01J23/882
Filed: 1956-05-14
Abstract: Cobalt molybdate is deposited on a catalyst carrier by treating the carrier with a mixture of a solution of cobalt acetate and a solution of ammonium molybdate at a temperature above about 120 DEG  F., the solutions being mixed in such a manner that substantially no precipitation of cobalt molybdate occurs before the catalyst carrier is brought into contact with the solutions.  The two solutions and the carrier may be mixed at room temperature and the mixture then heated to about 150 DEG  F. to precipitate cobalt molybdate; alternatively the solutions may be heated separately to 120-150 DEG F. or higher and then mixed with the carrier.  The carrier is preferably alumina, which may contain a small amount of silica, or active carbon.  The mixture of solutions may be added to a hydrosol, hydrogel, or slurry of alumina; the mixture of the solutions and the hydrosol may be spray dried to form microspheres.  The impregnated carrier may be dried at 200-600 DEG  F. and activated by heating to 1200-1500 DEG  F., the catalyst being prepared in suitable form by extrusion, filling, or granular drying.  In examples: (1) a 3 per cent alumina sol, prepared by hydrolysing aluminium alcoholate, is mixed with solutions of cobalt acetate and ammonium acetate, and the mixture heated to 150 DEG  F.; (2) alumina is prepared by mixing solutions of sodium aluminate and aluminium sulphate and after calcining is mixed with hot cobalt acetate and ammonium molybdate solutions to form a catalyst containing 5 per cent CoO and 10 per cent MoO3. The catalysts may be used for the hydrodesulphurization, hydroforming or hydrocracking of petroleum fractions.  Conditions suitable for hydrodesulphurization are a temperature of 400-800 DEG F., a pressure of 200-400 p.s.i., a throughput of 1-16 v./v./hr. and a hydrogen consumption of 30-500 cu. ft. per barrel of feed. In Example 3 the catalyst is conditioned by vapour phase contact with light virgin heating oil, followed by contact with heavy catalytic naphtha, at 600 DEG  F., 200 p.s.i.g. pressure, and using 1500 cu. ft. per barrel of added hydrogen; desulphurization is then performed on a heavy virgin gas oil.
