Title: An improved apparatus for estimating the dry rubber contents of latices
IPC: G01N9/36
Filed: 1948-02-05
Abstract: 652,283. Weighing-apparatus. HATFIELD, P. W. Feb. 5, 1948, No. 3349. [Class 143] A spring balance, or other weighing apparatus, is provided with a tabular chart showing weights of dry rubber according to weights and specific gravities of latex, the columns of the chart being identified with markings of an associate hydrometer which is inserted into the batch being weighed. In the apparatus shown, the batch is suspended on an eyelet 19 supported by a weighing spring 15 whose downward extension is communicated, through a tubular member 21, to the tabular chart 24 which moves on vertical guides 25 behind a transverse index aperture 27. A horizontal scale of specific gravities is marked off immediately above the index aperture 27, the markings corresponding to those on the stem of the hydrometer (not shown), and each being in alignment with a column of the chart 24. The weight of dry rubber in the batch is then shown in the aperture 27 under the specific gravity figure as read from the hydrometer. The eyelet 19 is connected to the spring 15 by a rod 18 on which is threaded a cap 20 secured to the tubular member 21, so that the tare can be eliminated by turning the cup and then securing it by a lock-nut 22.

Filed: 1923-02-05
Abstract: 210,627. Gimson Shoe Machinery Co., Ltd., and Bagshaw, C. M. Feb. 5, 1923. Pulling-over.-Relates to machines of the type in which mechanisms moved by power-driven means for pulling over an upper are upon completion of the pulling over operation, released and automatically returned to normal position under spring or like influence; and consists in the provision of a dash-pot applied to yieldingly control this return movement. As applied to the machine described in Specification 138,499 the dash-pot may comprise a piston 2 sliding in a cylinder 1 communicating with the outer air by a passage controlled by the conical end of a screw 14. The piston may be normally raised by springs 3. On the completion of a pulling-over operation and return of the pincers to normal position consequent on the descent of the end of the lever 19, the movement is cushioned by the dash-pot. In a modification, the dash-pot is provided with a non-return valve allowing free ingress of air.

Title: Method of and apparatus for regenerating ion-exchange materials

Abstract: 1,102,992. Ion-exchange. PERMUTIT CO. Ltd. 25, Jan., 1967 [26, Jan., 1966], No. 3545/ 66. Heading B1J. In a cyclic process wherein liquid is passed through a vessel containing a bed of a mixture of cation- and anion-exchange resins of different specific gravities, the bed is periodically regenerated by moving it as a slurry out of the vessel and introducing it into a stream of water flowing upwards at a velocity sufficient to carry one resin upwards but insufficient to prevent the other resin from moving downwards, removing the resins as separate streams, one upstream and the other downstream of the point of entry of the slurry into the upwardly flowing stream, regenerating the resins individually, returning them to the vessel and mixing them. As shown, ion-exchange treatment of water entering at 2 takes place in bed 4. When regeneration is necessary the resin from the bottom of the bed is fed as a slurry via pipe 19 to vessel 11 where there is an upward flow of water 14 which carries the lighter anionexchange resin via pipe 11 to regeneration vessel 21 while the heavier cation exchange resin falls in the stream and passes to regeneration vessel 24.

Title: Sintering method and sintering machine
IPC: C22B1/20
Filed: 1959-02-02
Abstract: 915,838. Sintering machines. NIPPON KOKAN KABUSHIKI KAISHA. Feb. 2, 1959 [Feb. 4, 1958 (2)], No. 3577/59. Class 82 (1). The pallets of a strand sintering-machine are used for sintering ore while travelling in one direction, and for cooling the sinter while travelling in the return direction, the pallets remaining upright during both directions of travel and the track being in a vertical plane with the cooling section being above the sintering section. Air is drawn through the sintered material in the cooling section and then employed in the sintering stage. In the apparatus shown in Fig. 2, pallets 9 are charged by devices 22 and 23 and ignited by furnace 25, combustion being maintained by the passage of heated air through the charge into windbox 37. On reaching sprocket 20, pallets are caused to dump their contents by means of the arrangement of rails 15, 16, 17 and 18, front and rear rollers of the pallets proceeding on different rails. The sinter passes through crusher 27 to hopper 28 from where it is conveyed by skip 29 to hopper 30, screen 31 and thence to the upper line of pallets for cooling. The cooled sinter is discharged on reaching sprocket 19 by means of rail system 15, 16, 17 and 18. An alternative method of discharging cooled sinter employing rail systems 43, 44 and 47 is shown in Fig. 4. For cooling the sinter air is drawn through into windbox 36 and subsequently into windbox 37. Windbox 36 is used also to extract dust from the ducts leading to crusher 27, hopper 30 and screen 31. When the charge is to be sintered and cooled without intermediate discharge, the sprocket and rail arrangement remote from the charging end of the machine may be replaced by a device of the type shown in Fig. 5.

Title: Improvements in games of chance

Abstract: 1,056,341. Amusement apparatus. T. CATLOW. April 17, 1964 [Jan. 29, 1963], No. 3618/63. Heading A6H. [Also in Division G4] Amusement apparatus simulating horse racing operates automatically and continuously to pay out winnings at predetermined odds against bets placed. Horses are propelled along a track by endless chains the drives to which are interrupted at random by a uni-selector in series with a mercury switch, until one horse 'wins', and another horse finishes in 'second' place. As shown in Fig. 8 the wiper arm of the uniselector is stepped by a drive magnet SLS DM operated intermittently by a mercury switch SLS dm, and relay DR. Relay MR is also operated intermittently by a contact breaker mercury switch CB dm 2. At each operation of relay MR a second relay SR1. . SR6 will be actuated, depending on the position of the wiper arm SL52. Each relay SR1 . . SR6 when actuated deenergizes a clutch solenoid which interrupts the drive to one of the horses. When the horses in first and second positions reach the finish appropriate relays are actuated to stop the advancement of the other horses and to set up paying out circuits. Figs. 10 and 11 show paying out circuits for two cubicles. A bet placed in the first cubicle (Fig. 1, not shown) for a 'win' or a 'place' closes one of the switches A1-M1 which activates one of the relays 1W1---1W6, 1P1---1P6. A contact in Fig. 10 corresponding to the relay operated is made. Upon closing of the appropriate contacts corresponding to the first and second horses, pins on cams W6<SP>d</SP>--W1/-, P1----P6 will cause the corresponding switches to be closed and thus cause the pay out solenoids to pulse. Each pulse releases a coin to the appropriate cubicle (Fig. 4, not shown). The odds of the winner are determined by a wiper arm ganged with the wiper arm SLS2, which actuates one of three relays Po 6<SP>d</SP>, Po 9<SP>d</SP>, PO 1/- (Fig. 6a, not shown). A clear down relay is then operated to return the circuits to their original state, and upon the cam shaft completing one revolution the clear down relay is released and the drive to the horses is re-engaged to return the horses to the start. Another race is automatically commenced when all the horses are at the start.
