Title: A method and apparatus for the removal from air, of paint and other materials insoluble in water
Inventor: BOYCE GUY BARON
IPC: B05B15/12
Filed: 1960-07-30
Abstract: 941,054. Washing air. ALFRED BULLOWS & SONS Ltd. June 2, 1961 [July 30, 1960], No. 26620/60. Heading B1R. A method of removing water-insoluble materials, e.g. paint, from air comprises passing the air over a cleansing liquid 11 which includes an emulsion of oil and alkaline water e.g. water containing sodium triphosphate or sodium metasilicate, so as to entrain droplets of the liquid in the air. The oil, which may be waste lubricating oil, is preferably present to excess to form a film on the liquid. A fan, not shown, draws the air over the liquid 11 in a tank 10 and under the serrated edge 15 of a plate 14 where it is directed by a plate 16 into a duct 12 containing baffles 13. A film of oil and emulsion is formed on the paint particles which are thus prevented from coagulating, thus allowing the alkaline substances to saponify resins in the paint. The liquid droplets and paint particles fall down the duct 12 and one or more channels 17 which communicate with one or more inverted troughs 18 in the tank 10. A weir 19, having a notched upper edge, forms a trap for paint particles in each trough 18.

Patent GB-405391-A (GB)
Title: Improvements in and relating to the treatment of alkaline-earth carbonates
IPC: C01F11/18
Filed: 1932-09-26
Abstract: Calcium, strontium, barium, and magnesium carbonates are purified or graded by dispersing the finely subdivided carbonate with a dilute aqueous dispersion of a gum, such as gum arabic or gum tragacanth, separating undeflocculated material, and recovering the carbonate from the suspension, as by film-drying, filtration, or flocculation by a neutral flocculating agent such as gelatine or glue.  A carbonate on the alkaline side of neutrality may be obtained by using a gum dispersion containing a small proportion of an alkaline reagent such as an alkali hydrate, carbonate, or silicate.  The presence of alkali silicate also assists the dispersion of difficulty suspensible carbonates such as certain native magnesites or native barium carbonate.  Numerous examples are given, and in the Provisional Specification the effect of the presence of alum in the dispersion is exemplified. The products may be used as a base in paints, printing inks, or in the striking of colours, in leather dressing, in medicine, and in the manufacture of rubber; in the latter case the alkaline product combines the effects of a reinforcing agent and a filling material, an example showing the reinforcing properties of "dispersed whiting" being furnished.ALSO:Calcium, strontium, barium, or magnesium carbonate which has been purified or graded by dispersion with a dilute aqueous suspension of a gum and separation from undeflocculated matter by film-drying, filtration, or flocculation by gelatine or glue, is used in rubber mixes.

Filed: 1960-08-02
Abstract: 901,147. Packaging-machines. VOGT, C. W. Aug. 2, 1960, No. 26721/60. Class 94(1). Powder is blown into open-topped containers through an aperture in a foraminous filling member and the container is moved relative to the member to compress the powder. The containers may be supplied as a preformed sheet or may be formed by vacuum drawing a sheet of plastic M into cavities in moulds 10A on an intermittently rotated wheel 10. The filling means comprises a hopper 35 having rotatable outlet valves 39, 40 which, after having permitted material to fall through passages 41 into filling funnels 56, 57, are rotated 90 degrees to the position shown. Each mould is raised by means 21, 22, to bring the containers into contact with a frame 68 on the filling means and air or neutral gas then enters through screens 50 to blow powder from the valves and funnels through apertures 59, 60 into the containers 11, 12. The gas escapes through the foraminous member 61 and vents 62, 63. The frame 68 is mounted for vertical movement relative to the filling means by cam bars 75, and after filling, it rises with the mould 10A. This causes the fixed member 61 to approach the container mouths and thus compress the powder. The mould and frame are then lowered and the containers may be sealed by application of a cover sheet (not shown).

Abstract: 1471320 Weighing electrically TANITA CORP 18 June 1974 [18 June 1973 5 Sept 1973]  27046/74 Heading G1N A digital display weighing apparatus includes a pointer 1 angularly displaceable proportional to applied weight and having a depending member 11  at one end thereof arranged to pass between a permanent magnet MG and a reed switch LDSW so as to de-energize a relay R Y. Rotation of the pointer by an applied weight allows the energization of the relay RY to close contacts t 3 -t 5  so motor M is energized to rotate a worm W and worm-wheel 3 to follow the pointer until the member 11 is at a position where it again screens the reed switch from the magnet MG so the contact ct 2  short-circuit the motor and it stops. To provide a number of electrical pulses corresponding to the rotation of the motor and thus to the angular displacement of the pointer, the motor shaft carries a permanent magnet MG 1  which acts with a further reed switch LDSW 1  to provide a pulse for each incremental rotation of the pointer corresponding to 0À25 kg weight. These pulses are gated through NOR 1  to counter CC linked with digital display unit DSP. The holding circuit HDC acts to maintain the weight display at DSP even when the pointer has returned to its initial position following removal of the weight until another weight is applied. Preset circuit RSC then acts through NOt circuit NOt 1  to reset the counter CC whereupon the display unit reads zero. Sensing of the member 11 may be photo-electric, Fig. 3 (not shown) or by a Hall plate Fig. 4 (not shown) or by a variable/magnetic reluctance device Fig. 5 (not shown). Motor rotations may be sensed by an apertured disc and photoelectric transducer Fig. 6 (not shown) or by a Hall effect switch Fig. 7 (not shown).

Abstract: 964,664. Transistor switching circuits. SIEMENS & HALSKE A.G. July 10, 1963 [July 11, 1962], No. 27268/63. Heading H3T. An electronic switch comprises a reciprocally coupled, complementary pair of transistors having a transformer coupled to the base circuit. As shown, the PNP transistor T1 and the NPN transistor T2 are reciprocally coupled so that both transistors are either conductive or non-conductive. The circuit is triggered by pulses fed to winding W3 of a transformer U- formed by passing three single leads through a ferrite ring. The time constant of the transformer may be short so that the input pulses are differentiated, the transistors being turned on by the differentiated pulse corresponding to the leading edge of the input pulse and turned off by the differentiated pulse corresponding to the trailing edge. Alternatively, resistor Rp may be connected across winding W3 so as to increase the time constant and allow the transistors to be turned on by the first input pulse at winding W3 and turned off by the next input pulse of reverse polarity. Fig. 5 (not shown), relates to the use of the circuit to gate pulses fed in series with the power supply.

Title: Improvements in or relating to tape driving mechanism
Inventor: BRINK ROBERT MORRIS
IPC: G11B15/26
Filed: 1954-09-22
Abstract: 746,734. Feeding webs. TIME, Inc. Sept. 22, 1954, No. 27442/54. Class 100 (1).  Mechanism for moving a tape intermittently comprises a tape drive which yieldably engages a length of the tape and continuously urges the tape in one direction, a pair of jaws between which the tape passes before reaching the tape drive, and a jaw actuator for causing the jaws alternately to open to free the tape and to close to grip the tape and bring it to rest. A magnetic tape 10 (Fig. 1) having groups of indices 80, 81 thereon is drawn over a pick-up head 84 by endless bands 14, 15 running around driven and idler rolls 16, 17 and 38, 39 respectively. The rolls 16 and 17 are mounted in standards 20, 24 on a base 18 whilst the rollers 38, 39 are mounted on brackets 42, 45 on a plate 40 which may be adjusted vertically by co-operating standards 52, 53 and screws 54, 54a. The rollers 16 and 38 are driven by belts 31, 50 from a motor 37. The bands 14, 15 frictionally engage the tape so as to drive it forwardly but if the tape is gripped the bands 14, 15 are adapted to slip over the tape until it is released. The tape is gripped between a fixed jaw 60 and a jaw 61 mounted on an arm 65 pivoted on a rod 64 and held in open position by a solenoid 68. When the solenoid is deenergized the jaws are clamped together by springs 69. Rollers 86 and 88 hold the tape in contact with the pick-up head 84 and a roller 57 is provided for holding the tape between the endless band 14, 15. Loops 75, 76 are maintained at both ends of the apparatus by photoelectric devices 77, 77<SP>1</SP> controlling motors 79, 791 operating feed rollers 71, 72 and 73, 74 respectively. The indicia markings 80 convey information via the pick-up head 84 to a photo-composer for the performance of a printing operation. The markings 81 serve to control the movement of the tape. In operation, the signal from the mark 81 is fed through a delay circuit to a multi-vibrator controlling the conductivity of a thermionic valve in turn controlling the solenoid 68 (Fig. 2, not shown), so that the solenoid is de-energized and the tape clamped by the jaws 60, 61. Upon completion of the printing operation by the photo-composer in accordance with the indicia markings 80 the photo-composer passes a second signal to the multi-vibrator so that the solenoid 68 is again re-energized to free the tape 10. Instead of the lower endless band 14 the tape may be held against the upper band 15 by air blast acting in a groove arranged below the tape (Fig. 4, not shown). The tape may alternatively be driven by passing it through two slots 122, 123 in a vacuum box 120 of a width substantially equal to that of the tape, suction being applied through a port 124 so as to draw the tape into the box 120. A photo-electric device 125 controls the size of the loop 76c which is formed in the box through rollers 73a, 74a in the same way as the rollers 73, 74 in Fig. 1 are controlled.
