Patent GB-109488-A (GB)
IPC: G07F17/38
Abstract: 109,488. Jofeh, J. Sept. 18, 1916. Tivoli billiards and the like.-In apparatus of the type in which a player endeavours to catch a ball in a movable cup, the player, if sufficiently skilful, is'permitted a number of successful operations for the insertion of a single coin, the ball is returned into play after each sudcessful operation, a token is delivered after each of certain numbers of successful operations, and a coin or a number of coins after a different number of successful operations. In the arrangement shown, thirteen successful operations are permitted, an indicating disk 11 being provided, which is rotated one step after each successful operation, and carries a pointer 10, Fig. 1, working over an indicator comprising representations of dominoes, a projection 26 on the disk engaging a fixed buffer 25 when the disk has completed a revolution: the particular successful operations which result in the delivery of prizes may or may not be disclosed to the player. The number of points scored by each player may be indicated by a disk d moving with the pointer and bearing numbers visible through an aperture 73 in the board. The disk 11 is provided with lugs 12, four of which carry short pins 13a serving to operate. the token-delivery mechanism, and one of which carries a long pin 13 adapted to effect the delivery of a coin or coins. A ball caught in the movable cup 3 passes into a pocket in a bar 27 connected to an external handle. After a successful operation, the player rotates this handle and moves the bar 27 to the right, Fig. 2, the ball lifting a detent 31 from engagement with a notch 32 in the bar, and a pawl 28 on the bar rotating the disk 11 one step: simultaneously a token-delivery slide 24 is moved over a tilting table 22. If one of the short pins 13<a> is adjacent a pawl 14 on a lever 15, the rotation of the disk 11 causes the pin 13<a> to rock the lever 15, and, through a link 21. lower the table 22, permitting the delivery of a token. If, however, the long pin 13 is adjacent the inclined end 42 of a lever 40, the tilting bottom 35 of a coin receiver 58 is lowered, permitting the coins contained in the receiver to pass to the player. Inserted coins are directed alternately to the money box and to the receiver 58 by a pivoted deflector 56; when the receiver 58 is full, further coins pass on to the money box. At the commencement of the game, the disk 11 is zeroized by an helical spring s when a pawl 60 is tripped from engagement with one of the lugs 12 by a spring-controller lever 63, which is operated from a disk 67. The player must rotate the disk 67 to withdraw a stop 45 from the coin shoot and permit the inserted coin to pass down the shoot and trip a lever 48 carrying a gate 6, so as to allow the balls 5 to pass into play. A spring-controller-shutter 74 cooperating with a earn 76 on the projecting-plunger serves to separate the ball to be projected from the remaining balls each time the plunger is operated.

Abstract: 1363969 Wire rope ends; inserting wedges NAUCHNO - ISSLEDOVATELSKY I OPYTNO-KONSTRUKTORSKY INSTITUT AVTOMATIZATSII CHERNOI METALLURGII USSR 9 March 1972 10960/72 Heading D1T A device for inserting cylindrical wedges into a butt end of a wire rope comprises a housing 1, Fig. 1, holding extended, telescoping tubes 2-5 held in position by annular, expanded rings 6-9. Tubular spacers 10-13 are held on the tubes by locks 14-17. Bushings 28-31 have cylindrical portions inserted between the spacers, and tapered portions extending to support wedges 23-26. Bushing 27 is supported in tube 5, and supports wedge 22. To insert the wedges, housing 1 is advanced by a hydraulic piston-cylinder unit and, Fig. 4, wedge 22 enters the annular gap between central wire 48 and wire layer 49. When wedge 23 enters the gap between wire layers 49 and 50 it stops moving. Lock 17 is then released, and further movement of all the tubular parts causes ring 9 to be contracted by stationary spacer 13 so that tube 5 and inserted wedge 22 stop moving. The wedges 23 to 26 are similarly inserted. When all the wedges are inserted to a depth determined by the release load of locks 14-17, the wedges are in alignment, Fig. 2, and the wedges are advanced together. The advancing wedges turn in the direction of wire lay. The bushings are moved all the way into the clearances between the spacers.

Filed: 1957-04-04
Abstract: 821,369. Preserving fish. BECKMANN, H. April 4, 1957 [April 13, 1956], No. 11053/57. Class 49. [Also in Group XIII] Cooling and preservation of protein and for containing foods, especially fish, involves subjecting the food to a high vacuum for degassing so that evaporation of liquid on the surface of the food results in cooling it to freezing temperature without freezing, and maintaining the food in degasified condition. The tanks 1, Fig. 3, are double walled and the space between the walls is lightly refrigerated by an evaporator with the coils wrapped in metal foil; alternati vely, the space may be evacuated or filled with insulating material. Water may be introduced into the tank after the initial cooling by means of a spray 5. Vacuum is created by a steam pump 4. The tanks may contain evaporator coils so that water vapour present may condense and freeze on the walls of the tank and the coils to form an ice reservoir. A stirrer may be provided to assist evaporative cooling. The tanks may be of a size to be removed easily from a fishing vessel, for which they are primarily intended, or may house smaller containers or trucks for the fish. In the latter case, after initial evaporative cooling of the fish, water is introduced into the containers and cooled until each container is sealed by a film of ice, or fresh or sea-water ice may be added to the tank during or before the vacuum process.

Title: Improvements in or relating to navigation aiding radio beacons and systems
Inventor: RUST NOEL MEYER
IPC: G01S1/68
Filed: 1954-04-15
Abstract: 778,213. Electric correspondence control systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. April 5, 1955 [April 15, 1954], No. 11206/54. Class 40(1). [Also in Groups XIX, XX and XL (c)] In a radio navigation system (see Group XL (c)) in which an unambiguous coarse indication of the bearing of a craft relative to a radio beacon is given by the angular position of the output shaft of a phasemeter CAP and an independent ambiguous fine indication of the bearing is given by the angular position of the output shaft of a phasemeter FAP such that the rotation ratio of the output shafts of meters FAP and CAP is 20 : 1, an accurate unambiguous bearing indication is given by a pointer SAP whose coarse position is determined primarily by meter CAP, the exact position of pointer SAP within any 18 degree sector being determined by meter FAP. As shown, the output shafts of meters CAP and FAP drive electrodes C1 and C3 of rotary capacitors C1, C2 and C3, C4. Each capacitor comprises a pair of electrodes each shaped as a sector of a cylinder; electrodes C3 and C4 are each semicylindrical, electrode C1 subtends an angle of 360/20=18 degrees and C2 subtends a much smaller angle. A motor M1 drives electrode C4 directly and drives electrode C2 and the pointer SAP through a 20: 1 step down gearing G1 such that when electrode C2 is centrally within electrode C1, capacitor C3, C4 is in the half capacity position. The two rotary capacitors are connected in parallel in the frequency determining circuit of an oscillator L0 such that the frequency of the oscillator is equal to the datum frequency of a frequency discriminator T1, T2 when electrode C2 is in the said central position and this condition is maintained automatically by applying the D.C. error voltage from discriminator T1, T2 to a relay RC1 controlling reversing contacts RR1 in the supply to motor M1. Pointer SAP then gives an accurate and unambiguous bearing indication. An accurate and unambiguous range indication is provided in a similar manner by a pointer SDP controlled by coarse and fine range meters CDP and FDP the corresponding components being indicated by a suffix.

The amount of fuel is controlled by the governor acting on the suction-valve, and the injection is timed by the valve 29, which is operated from the plunger cam 20 through a roller 21 and a lever 31 having an adjustable fulcrum. A single pump may supply two injection valves, the pump having two discharge valves and two release valves, which are separately controlled.
Patent GB-183243-A (GB)
Title: Process for the grading of alkaline-earth carbonates
IPC: C01F11/18
Filed: 1921-04-19
Abstract: Alkaline earth carbonates are graded by treatment in finely powdered form with a dilute aqueous solution of an alkali silicate.  The quantity of silicate required depends, to some extent, on the hardness of the water used, but is generally of the order of 0.5 to 1.5 per cent of the weight of the carbonate, a higher concentration being desirable in the case of magnesium carbonate.  In an example, a suspension of 120 lb. of whitening in 1554 lb. of soft water is treated with 1 lb. of sodium silicate in aqueous solution and the whole left to stand for one hour.  The upper portion is withdrawn, treated with 1 lb. of aluminium sulphate in aqueous solution, and allowed to stand for 1 to 1 1/2 days.  The supernatant liquor is then withdrawn, leaving a residue of very finely divided alkaline earth carbonate. As flocculating-agent for the very fine suspension a solution of gelatin or glue may replace alum or aluminium sulphate, and the flocculation process may be performed gradually, so that the sedimentation of the flocculated carbonate is retarded. Specifications 2379/11 and 27930/11 are referred to.ALSO:Alkaline earth carbonates are graded by treatment in finely powdered form with a dilute aqueous solution of an alkali silicate.  The quantity of silicate required depends, to some extent, on the hardness of the water used, but is generally of the order of 0.5 to 1.5 per cent of the weight of the carbonate, a higher concentration being desirable in the case of magnesium carbonate.  The carbonate is conveniently treated in the form of a 5 to 10 per cent mixture with water, when under the action of the silicate, the coarser material precipitates and may be separated, after which the alkaline earth carbonate is recovered from the suspension in a very finely divided form.  In an example, a suspension of 120 lb. of whitening in 1554 lb. of soft water is treated with 1 lb. of sodium silicate in aqueous solution and the whole left to stand for one hour.  The upper portion is withdrawn, treated with 1 lb. of aluminium sulphate in aqueous solution, and allowed to stand for 1 to 1 1/2 days.  The supernatant liquor is then withdrawn, leaving a residue of very finely divided alkaline earth carbonate.  From the tank in which the original silicate treatment was effected, about 48 lb. of coarse deposit is recovered.  As flocculating-agent for the very fine suspension a solution of gelatine or glue may replace alum or aluminium sulphate, and the flocculation process may be performed gradually, so that the sedimentation of the flocculated carbonate is retarded.

Title: Improvements in duplicating machines
IPC: B41L9/04
Filed: 1931-04-17
Abstract: 378,892. Copying documents. JOY, C. H., 457, North Racine Avenue, Chicago, U.S.A. April 17, 1931, No. 11488. [Classes 100 (i) and 100 (ii).] In copying machines of the kind comprising a carriage 6 movable over a gelatine printing surface 4 and supporting a platen roller 70 adapted to oscillate relatively to the surface, the upward movement of the roller is such that whilst the presser roller 51 remains in contact therewith the distance between the axis of the platen roller and a margin bar 40 does not vary. The platen is pivoted in arms 14 resiliently mounted on a shaft 12 carrying a handle, operable when locked to the carriage to reciprocate it or when unlocked therefrom to oscillate the platen. Projections 36 in the members 14 engage the forked ends of links 39 in which the margin bar 40 is pivotally mounted. The presser roller 51 is resiliently mounted in the links 39 and frame 6. When the platen is in raised position slots in the links and margin bar are in alignment to permit its removal. The paper is fed from a table 58 up to a shoulder on the bar 40 and the platen lowered into alignment with the stationary bar. A clutch 63 then engages the rim of the platen to prevent it rotating and the paper is fed downwardly by the motion of and pressure between the platen and presser rollers, the margin bar being rotated simultaneously by a link 45 pivoted at 46, 47 to the bar 40 and carriage respectively. The support surface 60 of the bar moves away from the edge of the paper which is fed to a position approximately parallel to the bed. The clutch 63 is then disengaged. by the link 45 and the carriage looking lever 75 released. By locking the platen roller against rotation at the point where it would engage the thinnest paper used, papers of varying thickness are fed to the same position on the bed.
