Title: Improvements in volumetric displacement apparatus suitable for controlling the supply of gas for chlorinating water or similar purpose
IPC: C02F1/76
Filed: 1927-03-16
Abstract: 277,869. Bramwell, B. March 16, 1927. Fluids, regulating volume of flow of.-A volumetric displacement apparatus suitable for controlling the supply of gas for chlorinating water and for other purposes comprises a displacement vessel a which is closed at the top and open at the bottom, and is contained in a closed vessel b to which water is led by a pipe f. A U-tube has its short leg c funnel-shaped and opening into the vessel a and its long leg d carried through the walls of the vessels a, b. Gas supplied by a pipe e to the vessel a depresses the water level in the vessel a and U- tube leg c until the seal in the U-tube is forced, a definite quantity of gas and water being thereby discharged through the leg d. The sudden release of pressure in the displacement vessel permits the water level to rise to the top of the leg c when the, seal is re-established. The vessels a. b are made of glass, celluloid, or other transparent material so as to allow the rate of displacement to be observed.

Abstract: 658,546. Sliver roll forming machines. FRASER & SONS, Ltd., D., and FRASER, H. March 21, 1949, No. 7569. [Class 120(i)] In a sliver-roll-forming machine having an endwise withdrawable arbor or pair of half-arbors provided with protruding pins or pin-like elements to engage the sliver, the pins or pin-like elements are individually set helically, i.e. skew to the axis of the arbor or half-arbor, their pointed ends being directed towards that end of the arbor or half-arbor last to emerge from the roll on withdrawal. As shown, Fig. 3, pins 1<1> are fitted at the larger ends of the halfarbors 2<1> of a machine of the type described in Specification 398,617, so as to point forwardly with respect to the direction of rotation; at commencement of winding the sliver passing between driver 6 and arbors 2<1> is arrested by an abutment 8, causing pins 1<1> to dig into the sliver. Pins may be similarly arranged. on the halfarbors of a machine of the type described in Specification 588,935, the arbors being initially driven with a surface speed slightly greater than the speed of travel of the sliver; or the pins may be orientated with their pointed ends trailing, the arbors then being driven at a lower surface speed than that of the sliver.

Abstract: 1426356 Welding by pressure P OPPRECHT 16 Feb 1973 [18 Feb 1972] 7845/73 Heading B3R In resistance seam welding using two electrode support rolls forming a co-operating pair, a single electrode wire passes twice in succession through the nip between the rolls to provide two wire lengths between which the work is welded, the electrode wire has been hardened by rolling or drawing to give it an elastic limit at the welding temperature which is greater than the pressure applied to the wire during welding and the cross-section of the wire is in a form bounded by a convexly curved work engaging crown and two equal flanks, either straight or convexly curved, which mutually converge to meet in a peak or hump. The wire electrode, e.g. of copper, is drawn or rolled prior to engaging the work, either immediately before or at the works, to increase tis hardness and strength. The wire electrode may have the cross-sectional shape shown in Fig. 2 or the electrode engaging flanks may be convex. Each face of the wire may be curved and of the same length so that the wire may be turned in the groove of the support roller and each face used in turn as the work engaging face.

Abstract: 311,501. Shone, T. March 14, 1928. Preserving fish, bacon, &c.-A house a for curing fish, bacon, &c., by smoking, having one or more exterior fireboxes g and means for controlling the passage of the combustion products from the fireboxes g to the house a, has a perforated metal plate d forming a dome, arch, &c. located beneath the roof b of the house a to divert condensed moisture towards the sides of the chamber and prevent it dropping on the food. The perforations may be formed in plate g by punching, their edges forming annular ridges on the upper side of the plate to ensure the matter condensed on this side passing to the sides of the house. In the construction described, the firebox g is connected by a passage h to the house a, a slidable damper i, Fig. 3, operated by a rod j regulating the supply of combustion products from the passage h. A perforated deflector plate h<1> is provided in the house a opposite the passage h. The combustion products leave the house a through a flue k, the inlet of which is at the base and is vertically adjustable, being locked in position by a bolt and wing-nut m engaging in a slot l therein. The upper end of the flue k leads to an outlet o which may be damper-controlled. An opening n controlled by a damper p is also provided in the inner wall of the flue k adjacent to the outlet o to permit the house to be cleared of the combustion products when desired. The inner wall and, if desired, the side walls of the flue are perforated. The house may have a hinged door fitting in a frame q. The food is suspended from bars e.
