Title: Improvements in or relating to concrete mixers and analogous machines
IPC: B28C7/02
Filed: 1930-02-04
Abstract: 347,327. Concrete &c. mixers. KING, A. E., 21, Dartmouth Row, Blackheath, London. Feb. 4, 1930, No. 3721. [Class 86.] In concrete &c. mixers, means are provided for preventing discharge before a prescribed number of revolutions comprising a stop in the form of a shaft screwed for a portion of its length the rotation of which, from the drum, effects its retraction from a position in which it prevents discharge. As shown, the stop B, which in its projected position engages the yoke supporting a rotary tilting drum, is rotated through a friction clutch member N splined thereto, the other clutch member M being driven from the main shaft X through interrupted gearing Y. As the shaft is rotated, a coiled return spring G is wound up until the traverse of the stop brings a collar P thereon into engagement with the clutch member N to throw out the drive. Return movement of the stop is prevented by a pawl H and ratchet F during this traversing movement. The pawl H is thrown out of operation by the charging hopper, the spring G being then free to effect the protrusion of the stop, the amount of which can be varied by means of a pin placed in one of a number of holes L.

Lever-actuated pumps; reciprocating - cylinder pumps; mountings. -A liquid soap container has a movable valved cylinder 9. reciprocated over a hollow piston 8 by a lever 14. During the upstroke of the cylinder, the soap is forced through the valved piston into the hollow head 7 and thence into the outlet tube 17. When the pressure in the latter tube is sufficiently great, liquid is ejected through the valve 19 and the nozzle 21, throughout the discharge stroke. The apparatus is supported by the lug 23 engaging the socket 22 and by an outer tube 24, surrounding the tube 17, which is locked in position by screwing the nozzle against the base.

Abstract: 1504496 Coagulating scalpel RESEARCH CORP 31 Jan 1977 [9 Feb 1976] 03874/77 Heading A5R A surgical scalpel 10 comprises a transparent blade 12, preferably made of artificial sapphire a flexible fibreoptic waveguide 20 having one end received in a notch 22 in blade 12 and the other end optically coupled to a laser whereby the laser radiation is transmitted into the blade 12 and coagulates blood adjacent the cutting edge 14. The laser is preferably an argon laser, the emission of which is selectively absorbed by blood. A pressure-sensitive power control 18 is provided on handle 16 and is connected by leads to a power adjustment circuit which controls the power supply for the laser. Alternatively, an optical sensor (not shown) may be placed at the-top portion of the blade, whereby an excessive amount of internally reflected light is sensed to control the power adjustment circuit. An optical element such as a lense, prism, grating, or polarizer may be placed between the waveguide and blade or between the waveguide and laser in order to control the rate and distribution of radiation leakage at the cutting edge. In an alternative form of transparent blade, Fig. 4 (not shown), radiation is injected into the blade parallel to the longitudinal axis through an end wall and is reflected toward the cutting edge by the other end wall which is sloped and preferably curved. The scalpel may alternatively comprise a steel blade sandwiched between transparent plates optically coupled to a laser, or a steel blade having a plurality of spaced waveguides embedded therein.

Roller and - ring mills. - In a roller- and-ring mill of the type shown in Specification 221,743 the upper portion of the pendulum shaft 9 is secured for suspension in a substantially upright position, a lubricant passage 16 extends axially through the shaft, a collar 24 is mounted on the shaft, a roller 25 is adapted to rotate on the lower portion of the shaft beneath the collar, a lubricant well 30 is provided on the roller below the lower end of the shaft, a supporting sleeve 31 is adapted to rotate above the collar, means 36 is provided for securing the roller to the sleeve, and a sealing means 50 is provided between the upper end of the sleeve and the shaft. The rocker 5 has a split collar 6 adapted to grip a trunnion shaft 4 mounted in bearings in the rotary spider 1, Fig. 2, and another split collar 7 at right angles to the collar 6 grips the pendulum shaft 9, endwise and rotary movement of the shaft being prevented by a split ring 12 and flange 14 and a longitudinal key 11 respectively. The roller 25 is provided with a bush 27 with flange 28 which abuts one side of the collar 24 on the shaft 9, the other side of the collar being provided with a thrust ring 38 which abuts a thrust ring 37 fixed to the sleeve 31 fixed to the rollar 25 by bolts 36. The upper end of the sleeve is provided with a bushing 43 and a. gland 49 in contact with a hardened steel bush 45 secured to the rocker 5. Lubricant from a central system as described in Specification 305,548 may be supplied by a flexible pipe 22 to a reservoir 17 in an axial bore of the shaft 9, the end of which is provided with a filter 18. The axial bore is continued at 16 to the end of the shaft 9, a reservoir 30 being formed in the roller 25 and an annular reservoir being formed at the end of the bushing 45 which communicates with the central bore 16 through an orifice 53. When the mill is working the oil descends through the central bore and ascends along the outside surface of the shaft 9, a small amount escaping through the gland 49. When the roller is at rest, the head of oil in passage 16 forces oil through the orifice 53 but when the roller is in operation the upward flow of oil outside the shaft will tend to counteract the outward flow through orifice 53 so that no movement of oil occurs. In a modification the end of the shaft 9 is conical and is connected to the rocker by lock nuts. the roller is provided with a flange by which it is connected by bolts to the flange of the sleeve 31 and the steel bushing 45 is omitted.
