Title: Densification of carbon black
IPC: C09C1/56
Filed: 1965-03-12
Abstract: A method of densifying carbon black, which comprises evenly distributing a stable oil in the form of a fine mist on to a bulky mass of loose carbon black in a confined zone, the addition of oil being accompanied at substantially all times by agitation of the mass insufficient in intensity to form pellets, the rate of oil addition being limited to a rate which is no greater than that at which the oil is readily taken up by the particles and not great enough to produce localized accumulations of oil within said mass, the amount of oil employed being 5 to 32 parts by weight per hundred parts black.  Any black may be used.  The oil may be of vegetable, mineral or synthetic origin and preferably has a midboiling point of about 350 DEG  F.  Exemplified are linseed oil, fatty oils, tall oils, rubber extender oils and news ink vehicle oils.  In batch processing, agitation must begin before or at the same instant as the addition of oil.  In a continuous process all of the black undergoing treatment should be under agitation at all times.  The oil may be introduced by impingement of an oil stream against a stream of gas or vapours or against a fan.  The oil may also be introduced by way of a nozzle or nozzles directed downward on to a bed of carbon black When a high viscosity oil is used it may be necessary to preheat it to e.g. 200-500 DEG  F. and spray under considerable pressure.  A plurality of small nozzles may be used the droplets striking the mass of black before the walls of the zone and the spray patterns are arranged so that they do not intersect and are closely adjacent at the point at which they intersect the surface of the bed.

Title: Improvements relating to the production of insulating coatings by spraying fibre
Inventor: DOLBEY NORMAN LOUIS
Filed: 1952-04-28
Abstract: <PICT:0741286/III/1> <PICT:0741286/III/2> Apparatus of the kind described in the Specification 368,368, for spraying asbestos or other mineral fibre simultaneously with an adhesive or the constituents thereof on to surfaces e.g. ceilings, for heat or sound insulating purposes, comprising mechanism for forming the fibres into a suspension in air and a fan which blows this suspension through a hose to a spraying nozzle, is characterized in that the fan is separated from the suspensionforming mechanism by a length of hose and is at a substantial distance along the total length of the hose from the mechanism to the nozzle.  The tendency of the fibre to clot up in the hose is offset by the opening action of the fan, so that a long hose can be used.  As shown, partially-opened fibre delivered by the spiked conveyer 4, Fig. 2, of a hopper feeder is sprayed with water from nozzles 16 to prevent release of dust and is stripped by a brush 10 on to a revolving perforated drum 12, whence it is entrained in the air stream leading through a fishtail nozzle 18 and a hose 20 to a fan 22, Fig. 1.  From fan 22 the fibre is delivered through a further length of hose 26 to the spraying nozzle 28.  The hopper feeder is driven by a motor 32; fan 22 is independently driven by a small motor 40 and may be located more than halfway from the hopper feeder to the nozzle 28.

Title: Improvements in or relating to cash registers
IPC: G06C7/10
Filed: 1925-04-27
Abstract: 232,983. National Cash Register Co., (assignees of Brown, W. C.). April 25, 1924, [Convention date]. Cash registers.-In machines, for example that described in Specification 192,083, provided with means for printing consecutive numbers and wherein a key is provided, as described in Specification 232,967, to disable the counter actuation for one or a series of operations, the key is pivotally mounted and is rocked to the right or left to perform its alternative functions. The disablement of the actuating link 47 is effected, as in Specification 232,967, by the leftward displacement of pitman 71 supported by bell-crank lever 72. A key 95 is pivotally mounted on a lever 91 pivoted at 92, and on being swung to the right or left rocks this lever, and therefore through pin 90 another lever 85 pivoted at 84. Thus one or other of two pins 86, 88 on the lever 85 are caused to depress a slide 82 having a lug 81 bearing against a pin 80 on the bell-crank lever. When the key is rocked to the left the lever 91 is detained by a pawl 101 engaging a notch 100 in the lever, the pawl then having its tail within the path of the releasing arm 104. If the key is rocked to the right, however, the pawl engages a notch 106, but the relative position of the pawl is not changed thereby, so that the releasing arm 104 is unable to latch the key. When in this condition, the parts may be freed by depression of the key, a projection 107 thereby rocking the pawl to disengage it from the notch.

Title: Improvements in or relating to washing machines
Inventor: MATTHIAS EUGEN
IPC: D06F37/30
Filed: 1951-05-09
Abstract: 695,414. Washing-machines. DANIKER & CO., L. May 9, 1951. No. 10923/51. Class 138 (ii). [Also in Group XXIX] A washing-machine having a working member which is reciprocated by means of a motor driven by fluid under pressure comprises a control device having a multi-way cock with an automatically operated member which alternately permits the flow of pressure fluid to the motor and the removal of the fluid therefrom, and the automatically operated member is combined with a motor which is rotated cotinuously in one direction by the pressure fluid. The invention is applied to a machine having a vertically moving agitator (not shown) moved downwardly by a piston acted on by the water under pressure and upwardly by spring mechanism. Water from the supply enters through an inlet pipe 2 and flows from a bore 4 in a cylinder 5 to a second bore 6 by way of two pairs of openings 12, 13 in the wall of the cylinder 5. The bores 4, 6 are separated by a partition 5a and connected through a doublewalled sleeve 8 rotatably mounted on the cylinder 5. The annular space 9 thus formed in the sleeve communicates with the openings 12, 13 in the position shown through openings 10, 11. The bore 6 is connected through a pipe 7 with the agitator piston (not shown). Some of the water entering at 2 passes through a passage 27 to an adjustable nozzle, Fig. 4 (not shown) the jet from which impinges on the vanes of a vane wheel 18 causing it to rotate. The vane wheel 18 is mounted with a flywheel 22 on a shaft 19 carrying a worm 17 which meshes with a worm wheel 16 on the sleeve 8. The sleeve 8 is thus continuously rotated at a speed determined by the size of the nozzle, adjustment of this being effected by means of a knob 26. As the sleeve 8 rotates it closes the openings 12, 13 in the cylinder 5 and brings further openings 15 in the sleeve into line with openings 14 in the cylinder 5. The supply of water is thus cut off and the springs are free to raise the agitator again. The agitator piston forces the waste water through pipe 7 and openings 14, 15 into the casing 1 whence it escapes through an outlet 31. Specification 640,535 is referred to.
