Title: Method of and apparatus for washing gas
IPC: B01D47/06
Filed: 1928-08-20
Abstract: 321,252. Norgate, R. Aug. 20, 1928. Scrubbers and washers.-Gas washing apparatus comprises a series of chambers each having a liquid bath and an injector with a submerged liquid inlet, a gas inlet above the liquid level, and an inlet for pressure gas. A casing a is divided into superposed chambers c intercommunicating through staggered apertures d through which liquid supplied through an inlet u descends from chamber to chamber. Gas is supplied through an inlet s and pressure gas through a pipe n from which branches m lead to the injectors f. Liquid enters the injector casing g through the annular passage surrounding the pressure gas nozzle l and mixes with gas drawn in through a pipe z, the mixture being discharged through an annular slot h and a central hole i. Liquid may be drained off from the chambers through pipes o. In a modification the chambers are arranged in two superposed groups of four and the injectors are made up of three portions screwed together, constituting pressure gas and liquid nozzles and an outlet fitting into which a vertical open-ended gas inlet tube is screwed.

Abstract: 673,701. Crop sprayers. VENABLES, A. B. Aug 23, 1950 [Sept. 20, 1949], No. 24190/49. Class 69 (iii) An upright water supply pipe supports a number of atomising nozzles at different levels from the ground, the nozzles being spaced closer together in a vertical direction as they extend up the pipe. One or more such pipes, which may be connected to a main supply pipe either direct or through separate feed pipes, may have control cocks, and atomising nozzles may be spaced around the pipe or pipes in a helix, the pitch of which decreases as it extends upwards. Pipes located around the perimeter of the sprayed area have nozzles spaced around only half their circumference. The Provisional Specification states that the control cocks associated with the pipes arranged around the perimeter of the sprayed area may be controlled through wind vanes associated with water motors.

Title: Improvements in and relating to incandescent lamps
IPC: H01K1/32
Filed: 1957-07-30
Abstract: 846,934. Electric incandescent lamps. EGYESULT IZZOLAMPA ES VILLAMOSSAGI R. T. July 30, 1957 [Aug. 1, 1956], No. 24149/57. Class 39(2). An incandescent lamp especially for infrared radiation has a reflecting coating on part of the inner surface of the bulb, the remainder of the surface being given a coating of pigment of micron grain size producing a matt finish. In a method of producing a bulb, the coatings are applied successively in any order, the other coating being removed from those areas where it is not wanted. In one method, a pigment such as titanium dioxide in a solution of butyl acetate or acetone containing a binder such as collodion is applied to the bulb, the unwanted parts of the resulting coating are removed mechanically or chemically and a reflecting coating applied by evaporation, unwanted parts of this coating being then removed by chemical means. Alternatively, the reflecting coating is applied first, unwanted parts are removed and the remaining parts coated with collodion. The matt coating is then applied and the collodion coating together with the overlying matt coating removed. The outside of the bulb may be provided with a red lacquer coating or a red pigment may be fired on to the outer surface. Specification 695,081 is referred to.

Title: Thermal flowmeter
IPC: G01F1/684
Filed: 1963-06-18
Abstract: 974,690. Measuring fluid flow electrically. HASTINGS-RAYDIST Inc. June 18, 1963 [June 29, 1962], No.24165/63. Heading G1N. The rate of fluid flow through a conduit is determined by heating the conduit and measuring the temperature difference between two points along the line of flow using thermocouples of which one element is the conduit itself. In the basic embodiment (Fig. 3), the conduit 10 has a heat sink 12, 14 at each end whereby the ends are maintained at the ambient temperature. Heating is produced by a current through the conduit obtained from a transformer 26 connected to the ends 12, 14 of the conduit, and a meter M is connected between the centre point 32 of the conduit and the centre tap 30 of the transformer winding 28. The material of the transformer winding and the leads form the thermocouple with the material of the conduit 10 so that the meter M indicates the temperature difference between the mid point of the conduit and the ambient temperature, which temperature difference is indicative of the rate of fluid flow through the conduit. The meter M is in the balanced diagonal of the bridge circuit supplying the heating current, and therefore does not carry any component of the heating current. In further embodiments, (e.g. Fig. 11), the conduit 72 is looped and/or duplicated to enable at least one of the heat sinks to be earthed, and the meter M is connected between points on the conduits which are outside the heating current circuit or are balanced with respect to the heating currents, which may be induced into the conduits as shown by electromagnetic coupling, or by eddy current heating.

In a double glazed window enclosed by channel members 10 and 12, a breather is provided in member 12 which connects the space between the window panes to the atmosphere. The breather comprises a horizontal hole 22, Fig. 3, which extends through the member and a hole 23 which extends to a position opposite the centre of the space between the panes. The holes are enlarged over part of their depth to form chambers 29 and 30 which receive filter pads. The chambers are interconnected by a groove 33 formed in the member 12 and the groove and the open end of the chambers are covered by a sealing gasket and plate 34. Air enters or leaves the breather via a bored plug 40, which engages in hole 22 and is provided with a cross-bored projecting head 37 and via a tube 27, which interconnects the inter pane space and the base of the hole 23. The flow of air is limited by a plug 35 which is formed with a mutilated thread and is screwed into the hole 23. One of the chambers may contain a desiocant, e.g. silica gel. 914,854.

Abstract: 314,269. Bull, H. Aug. 25, 1928. Cream, separating.-In the extraction of fats from fat-bearing emulsions such as milk, the materials are intimately mixed, for example, in a grinding mill, with substances which combine with water such as sodium sulphate, burnt gypsum, or desiccated alums such as potash alum. When the material is rancid a small amount of sodium carbonate is added to neutralize the free fatty acids. Oil is extracted from the mixture, which may be a dry powder, by solvents or by pressure or centrifugal treatment. The residueafter extraction is treated with steam or hot water to yield a further amount of oil, an aqueous solution of the desiccant, and solids which may be treated to produce animal food.

Filed: 1923-10-04
Abstract: 227,161. Beevers, L., and Fieldhouse, Crossfield, & Co., Ltd. Oct. 4, 1923. Clutches, claw; operating clutches. - In onerevolution segmental-key clutches for presses, shearing-machines &c., the clutch-releasing trigger is pulled down by a notched link, which is so connected to a bell-crank actuating-lever and constrained by a fixed roller as to be rocked through an arc when depressed and thus to be disconnected from the trigger. A segmental key Q carried by the crankshaft 0 can be turned to engage a notch in the flywheel boss (not shown) by a tension spring connected to an arm on the key or by a coaxial helical torsion spring secured at one-end to the key and at the other end to an adjustable spindle X locked by a set-screw Y in a spring housing V. At its other end, the key Q carries an arm P movable in a gap S in a collar R, a set-screw T therein being engageable with a notch in the key to hold it disengaged while the shaft O is being turned by hand. The arm P is normally engaged by a trigger G having slotted engagement with its pivot H. The trigger is pressed by spring plungers L, M and carries a pin J engaged by the hooked end of a link C, which is held against a roller D by a spring F and is connected to a treadle or hand lever by a bellcrank lever B pivoted below and behind its point of attachment to the link. On depression of the link C to start the machine, the trigger G releases the arm P, the link C rocks backwards, and the trigger G slides forward on its pivot H, as shown in Fig. 3, so disengaging the parts C, J. Whether the treadle &c. is released or not, the trigger rises against a stop surface into the path of the arm P to declutch after one revolution. By removing the roller D, continuous running during actuation of the treadle &c. is obtained.
