Title: Improvements in or relating to record card controlled listing or tabulating or like statistical machines
Filed: 1930-11-07
Abstract: 365,689. Statistical machines. BROUGHAM, L. E., Brillig, Riddlesdown Avenue, Purley, Surrey. Nov. 7, 1930, No. 33604. [Class 106 (i).] In a perforated-cardcontrolled statistical machine a single cardcolumn controls a number of type-bearing members, e.g. two. For this, the column is divided into sections, e.g. two, each section having a special auxiliary perforation, the presence or absence of which decides the values of the remaining holes in the section. In the construction shown, the invention is applied to a statistical machine with swinging type sectors, which are differentially set as in Specification 26896/13, [Class 106 (i), Calculating &c.], and which are also controlled by swinging members of the kind described in Specification 108,942, [Class 106 (i), Calculating &c.]. In a card-field embracing five card columns, each column is divided into two sections ; the first section consists of hole positions B .. F and auxiliary hole position A ; the second consists of hole positions H . . L and auxiliary hole position G. Holes B . . F control, through offset extension rods ER, stops S to arrest differentially the heel on a swinging member AS locked to type sector TS No. 1 so as to position one of the type t 0 .. 4 opposite the printing platen P. If the auxiliary hole A is present then the special sensing pin SSP raises stop SSS with its extension AM so that the latter rotates lever LL to release lug AA on TS No. 1. The springs SS cause AA to move to the left-hand end of slot SL so that the member TS No. 1 has an additional movement, which thereby sets one of the type t 5 .. 9 opposite the platen P. The five holes B .. F and special hole A thereby control the setting of ten type t. Similarly the holes H .. L and special hole G control the setting of the second type sector TS No. 2. The nvention may be applied to machines in which the cards are read whilst they are moving; in this case the auxiliary perforations (A and G) would complete a circuit to modify the interpretation of the normal holes of the sections. For example, stops with compound or tapped windings may be used so that part of the winding is energized by normal holes and the whole when an auxiliary hole is also present. Alternatively, stops and actuating means for the latch (LL) as described in Specification 108,942 may be actuated electrically.

Title: Improvements in or relating to internal combustion engines
IPC: F02B1/00
Filed: 1922-12-11
Abstract: 211,995. Brookman, R. S., and Moss & Sons, Ltd., W. Dec. 11, 1922. Regulating.-A four-stroke engine using a variable combustion chamber to suit the volume of the air or mixture charge has the whole of the charge supplied by a pump during the suction stroke; the variation is accompanied by an alteration in the amount of water circulating through the cooling system, by an adjustment of the engine valves, and if two fuels are used by changing over from one to the other. An adjustable abutment 6 forming the cylinder head is connected by outside rods to an eccentric 10 on an adjusting-spindle 11; a second eccentric 23 on this spindle is connected to a hinged quadrant 20 in which moves the pin joining the pump rod 18 to a driving connecting-rod 21. The spindle 11 is turned through the gearing 45, 47 - - 50 and the clutch relay 52 - - 54 from the governor shaft 55 according to the movement of the governor. The eccentric 23 varies the position of the quadrant to give a variable pump stroke, this being zero in one limiting position. An arm 82 on the quadrant varies the position of a throttle valve 79 in the water-circulating system. Either petrol or paraffin are supplied through the three-way cook 34. A cam disc 46 on the spindle 11 has (i) a stop 73 for acting on linkage. 74 - - 77 connected to the governor muff so as to limit the working of the governor, (ii) a cam 70 for moving the fuel cock 34, and (iii) a cam 64 for moving the bell-crank 65 used to slide the valve cam 62 on the cam shaft 61; the bell-crank 65 is also connected by a link 69 to a crank 68 and catch 84. When the valve cam 62 is moved to bring a twostep cam 63 under the exhaust valve, the latter is held open on the normal compression stroke; as fuel is simultaneously cut off, the engine then works as a brake. The catch 84, during this period, holds the water throttle valve closed. The movement of the valve cam 62 can also be effected by hand from the rod 67 through the lever 68; this lever acts through the link 41 on a cam 40 for holding the fuel pump inactive. The rod 41 may be worked independently of the lever 68 to stop the fuel supply. In a modification, carburetted air is drawn through the pump, the rod 69 being connected to a throw-over valve which can be used to cut out the carburettor and connect the pump to the atmosphere.

Title: Refining metals
Inventor: PATON BORIS EVGUENIEVICH
IPC: C22B9/18
Filed: 1961-09-25
Abstract: <PICT:0979583/C6-C7/1> <PICT:0979583/C6-C7/2> In a process for refining metals and alloys, e.g. to remove gases and other inclusions, a consumable electrode of the metal to be treated is immersed in molten slag of higher melting point than the metal, and the metal is gradually melted by the slag and joins a mass of the same molten metal under the slag, the molten metal forming the second electrode, and the electric current flowing to it from the consumable electrode heats the slag.  The mass of molten metal is then cooled, and the slag of lower co-efficient of expansion than metal forms a separated sheath around the latter, and also forms a clearance with the wall of the vessel.  In examples tool and other alloy steels, magnet steels, non-ferrous metals and alloys may be treated, and the slags used include mixtures containing CaO, Al2O3. CaF2, MgO, TiO2, and B2O3.  The end of an electrode 7, Fig. 3, dips into molten slag 1 below which is a pool of molten metal 4 acting as the lower electrode, and resting on solidified metal, which is insulated from the vessel by solidified slag sheath 3 spaced by shrinkage gaps 5, 51.  The vessel 2 is provided with a cooling jacket formed by an outer wall of non-magnetic steel and an inner wall of copper.  The slag has a melting point 50-70  DEG C. above that of the metal electrode.  Either D.C. or A.C. power may be applied including 3-phase current supplied to three electrodes arranged in line or in a ring.  Multiples of three electrode rings may be used and more even heating is achieved by rotating the molten steel, by imposing a magnetic field from a surrounding electrically energized helix. In an alternative arrangement, Fig. 8, the metal electrode consists of a tube of the metal 71 surrounding a rod of the metal 7, a voltage of 15-30 V. being maintained between the tubular electrode and the melt 4, and 60-80 V. between the rod element and the melt 4.  The tube 71 may be replaced by a helical coil, and may also be of a different metal of higher melting point than the rod thus forming an alloy. The density of the metal 71 may be greater than the rod 7, when two slag layers are used, the slag 11 being less dense than rod 7, and slag 1 is intermediate in density between the two metals, so that molten metal from rod 7 floats on slag 1 within the tubular electrode which melts into the metal pool forming an alloy at 4.  An inert gas may be introduced into the free space.

Abstract: 1,005,838. Coffee-making machines. OFFICINE CIMBALI GIUSEPPE S.p.A. Sept. 7, 1962 [Sept. 11, 1961], No. 34440/62. Heading A4D. In a coffee-making machine in which, on raising plunger 10, hot water flows from boiler 13 to cylinder 2 simultaneously along two paths in which heat is dissipated unequally, one path 8, 7, 6 extends through part of the cylinder casing to port 5 and the other through duct 1 and port 3. The change in viscosity which occurs when the water in path 8, 7, 6 cools diminishes the amount delivered through port 5 at each stroke of the plunger and so maintains the mixing temperature in cylinder 2 constant, however much time elapses between successive operations of the machine. When the machine is operated several times in rapid succession, the excess temperature of flow path 8, 7, 6 and the flow rate through it are raised, thus maintaining the same contribution to the heat loss as before and preventing any change in the mixing temperature. The port 3 is advantageously smaller than the port 5. A non-return valve 17 is provided.
