IPC: B02C4/04
Filed: 1926-11-30
Abstract: 280,041. Torrance, J. R., and Torrance & Sons, Ltd. Nov. 30, 1926. Mixers combined with grinding or crushing apparatus. - A combination plant for the manufacture of paints, enamels, inks, &c. comprises a mixer or grinder, a mill system, and a finishing mill, the units being so arranged and related as to provide a. continuous process plant in which the material is mechanically or automatically fed or delivered from the mixer or grinder to the finishing mill without handling. A second mixer or diluter may be interposed between the mill system and the finishing mill. As shown, the dry material and oil are fed by hoppers 1 into an edge-runner mill 2 where it is mixed and partly ground. The mixture is discharged into a receiver 3 containing revolving stirrers mounted on a shaft 4, from which it is delivered through a slide-controlled opening 3<a> on to the first roll of a triple granite roll mill 5. From the mill 5, the mixture passes to a second triple granite roll mill 6, the finely-ground paste passing by a scraper tray 7 into a diluting mixer 8 which may be of the vortex type. From the mixer or diluter 8, the material is pumped into the hopper 9 of a roller finishing mill 10, which may he of the kind described in Specification 209,829, [Class 59, Grinding, crushing, Ac.]. The mixer 8 may be divided into compartments, or duplicate mixers 8 may be provided, so that while the diluted material in one compartment or mixer is being pumped &c. into the hopper 9 the paste is being delivered from the mill 6 into the other compartment or mixer. A tipping shoot may be provided over the mixers to deliver the material from the scraper tray 7 to the mixers, or the diluting mixer may be arranged directly over the finishing mill so that there is a gravity feed from the mixer to the mill, the paste being pumped if necessary from the tray 7 up to the mixer.

Abstract: 1,110,628. Movable fulcrum for spring- boards. R. C. RUDE. 6 July, 1966 [24 Sept., 1965], No. 30316/66. Heading A6M. A movable fulcrum for springboards consists of a drum 15 mounted in a cradle which bears slidably on two rails 24 which are part of the base. Movement is affected by turning the drive wheel 20 which is directly connected to and rotates the drum 15. The top of the drum bears against the bottom of the spring- board so that the rotating force on the drum is transferred into motion of the drum and cradle along the rails 24. The rails sit in grooves in the base of the cradle and both may be covered with a friction reducing material such as polytetrafluoroethylene. The drum may be ribbed along its length to increase its friction against the bottom of the springboard.

Abstract: Pile material (1) is corrugated between blades (5) and (6), which are movable in a series of guide grids (3) and (4) which traverse the machine, and an adhesive backing (11) is applied. Figure 4a (not shown) shows that a continuously moving conveyor (40) has levers (41) that push the guide grids (3), (4) out of supports (22), (60\sv) so that cam operated plates (75), (95) can move successive blades (5) and (6) (Fig. 5, not shown) out of the grids to corrugate the pile.

Title: Braking valve-gear for reversible engines
IPC: F01L13/06
Filed: 1935-11-05
Abstract: 448,086. Engine valve gear. CAPROTTI, A., 2, Via Pergolesi, Milan, Italy. Nov. 5, 1935, No. 30567. Convention date, Nov. 5, 1934. [Classes 122 (ii) and 122 (iii)] A valve-gear for a reversible engine is provided with means whereby variation of the valve's timing in comparison with the timing corresponding to the simple reversed motion may be effective to increase the area of the braking diagram. The whole valve-gear may be angularly shifted to advance the valve events relative to the valve events corresponding to the maximum cut-off in reverse. Special inlet and exhaust cams may be provided. A modification of the gear described in Specification 170,855, [Class 122 (ii)], to facilitate braking is described. To enable the result to be obtained in gears operated through rotating-shafts, an angular shifting-device is inserted in the shaft which allows the gear to be given a lead or a lag. The motion is transmitted from the axle E through wheels g, g<1>, universal joints u, u<1>, and a shaft E<1> coupled to the cam shafts. A counterweight F<1> may be added to cause the resulting force from impacts to pass through the axis of the axle. The retaining-link P may have spherical ends. The shaft E<1> is divided at E<1>1, E<1>2, Fig. 4, and connected by adjustable helical elements H, L. The valve-gear described in Specification 170,855 is modified as shown in Fig. 5, to render braking more effective. The inlet cams C, C<1> are driven from the shaft A through the screw V and scrolls M, M<1>. The scrolls are controlled by collars K, K<1> connected to the reversing-shaft A<1>. The lost-motion between the collars and scrolls is eliminated and a positive connection effected through the thrust ball race shown. The links J, J<1> are made in two parts connected by springs s which allow the links to increase in length by an amount corresponding to the eliminated lost motion. The exhaust cam D is driven in a fixed angular position by a piece N fixed on the shaft which engages a projection on the cam and one or the other of two spring-pressed latches T, T<1> carried by the cam. When the gear is reversed, the end of rod B on lead cam C detaches latch T and the cam D is carried forward and the latch T<1> engages recess t<1>. A plate Z secured to the shaft holds the catches out of action in intermediate positions. When the valve-gear is of the multicam type, Fig. 10, the shaft X is provided with additional admission and exhaust cams ul, y<1>, Fig. 11, to augment the braking effect of reversal.
Patent GB-452073-A (GB)
Title: Improvements in and relating to methods of electrical purification of gases containing elementary sulphur
IPC: B03C3/014
Filed: 1935-11-06
Abstract: Gases containing sulphur vapour together with other solid or liquid impurities are purified by passage through an electrostatic precipitation apparatus at a temperature between 400 and 200 DEG  C., at such a velocity that some sulphur is precipitated together with substantially the whole of the impurities, the main portion of the sulphur leaving the apparatus without deposition.  Coarse impurities may be separated first by treatment in a precipitator at such a temperature that no sulphur will be condensed.  The sulphur is deposited in the liquid state with the impurities silted therein. The process is particularly applied to the gaseous mixture containing sulphur obtained by the reduction of sulphur dioxide with coal, coke or other carbonaceous material.

Abstract: 1,110,321. Semi-conductor devices. SIEMENS A.G. 20 July, 1965 [21 July, 1964], No. 30765/65. Heading H1K. A semi-conductor device is made by forming a mesa in the surface of a sem-conductor body of one conductivity type, providing an oxide layer on the flanks of the mesa and then diffusing an impurity down the mesa to form an oxide protected PN junction. In a typical transistor of this type, Fig. 8, the me a is defined by a moat 24, the emitter zone 20 and contact 21 are linear and the base contact 22 U-shaped. Such a transistor is conveniently made by etching to form the mesa in an N- type silicon wafer, oxidizing or depositing oxide on at least the flanks of the mesa and then diffusing boron into the mesa face to form the collector junction. Subsequently, phosphorus is diffused through an aperture in oxide masking to form the emitter zone and emitter and base electrodes 21, 22 and collector electrode 15 formed by alloying aluminium and goldantimony respectively to the wafer. In forming a diode contacts are made to the bulk of the wafer and to the first diffused region. The oxide coating may be formed by evaporation, pyrolysis, or anodic oxidation or by oxidation during the early stages of the diffusion step.
