Title: Method of and means for converting rotary into oscillatory motion
IPC: B06B1/12
Filed: 1921-02-19
Abstract: 171,349. Tekniske Forsogsaktieselskab. Nov. 9, 1920, [Convention date]. Machinery, utilizing inertia to obtain movoments in.- A crank linkage comprises a reacting inertia. member and is applied for driving power r hammers. hack-saws, vibratory aircraft propellers, &c. The essence of the device appears in Fig. 3. A pulley G mounted in a block V is connected by a crank A' and rod B' to a mass W, the masses V and W being both slidable in guides C. When the pulley drives, the masses V, W reciprocate in opposite directions, and according to the invention, the mass or block V is caused to do work. The effect of the inertia of the resisting mass W is increased by making the elements A', B' equal in length, so that the mass W passes from side to side of the mass V. Lateral thrusts are eliminated by employing a duplicate linkage A<2>, B<2>. The active mass V may be positioned and controlled by adjustable resilient buffers. In the application to hammers, eccentrics replace the crank and rod. as shown in Figs 6 and 7. A shaft 0 driven through a sliding coupling drives eccentrics A<1>, A<2>, A<3> journaled on a, gudgeon R upon the mass V, the eccentrics A<2>, A<3> being driven in the opposite direction to the eccentric A'. Enveloping eccentrics B<1>, B<2>, B<3> connect to the resisting mass W and form part of the resisting mass. Such a hammer is shown in Fig. 15. The mass V is controlled by buffers X, U actuated by handwheels Z<1>, Z<2>, and the shaft 0 is driven from a motor D through a shock-absorbing spring Y. A form suitable for driving aircraft propellers is shown in Fig. 8. The vibratory propeller carries the mass V and a fixed sun gear S<1>. An arm A carrying planet gears S<2>, S<3> is driven through a flexible shaft O. The mass W is carried on an arm B secured to the gear S' so as to be reciprocated past the mass V in a horizontal path.

A particular way of calculating the PSC of a powder is specified, and an equation giving the apparent density in terms of PSC, mill speed, and mill gap is given. Preferably, at least 95% of the particles as atomized are finer than 80 mesh. The annealing is carried out in a decarburizing reducing atmosphere e.g. hydrogen or dissociated ammonia to reduce the carbon content to below 0À1%, preferably below 0À01%, from a value of up to 0À8%, preferably below 0À15%, and the final powder preferably has an apparent density less than 2À6 gm/cc. The apparent density may be slightly decreased by using temperatures at the higher end of the range, e.g. 1800-2100 F.

Abstract: 712,976. Wire strainers. STRESSED CONCRETE DESIGN, Ltd. March 13, 1951 [March 13, 1950], No. 6282/50. Class 45. [Also in Group XXX] A hydraulic jack or tensioning device particularly for use in stressing re-inforcing wires in prestressed concrete beams or structures, comprises a cylinder 2 within which moves a piston member 3, relative movement between the cylinder and piston effecting the jacking or tensioning operation, the cylinder being provided with a pump 7 having its inlet connected to the cylinder at one side of the piston and its outlet to the cylinder at the other side of the piston whereby the space in the cylinder to which the inlet side of the pump is connected normally acts as a reservoir for the oil or other fluid used for operating the jack, operation of the pump forcing the liquid to the other side of the piston to move the latter within the cylinder and wherein the piston is pressed by a spring 5 in a direction away from the reservoir end of the cylinder. The spring 5 surrounds the piston rod and acts between a washer 6 on the piston rod and a pressure plate 1 from which the cylinder projects and through which the piston rod passes. At the opposite end of the cylinder from the pressure plate 1 is the pump 7 which is hand-operated; the inlet of the pump communicates with the adjacent end of the cylinder 2 and the outlet communicates by means of a pipe 23 with the pressure plate end of the cylinder. A pressure gauge 24 is provided in the pipe 23. By operating the pump 7, fluid is transferred from the pump end of the cylinder to the opposite side of the piston and so retracts the piston rod and applies tension to wires 53 which are connected to the piston rod by a releasable clamp 41 of the type described in Specification 713,059, [Group XXV] , When the wires have been sufficiently tensioned they are anchored by a clamp of the type disclosed in Specification 690,981 and after the clamp 41 is released, the pipe 23 is connected to the pump end of the cylinder by opening a valve 27 which bye-passes the pump; the spring 5 then returns the piston and the fluid to their initial positions. The valve 27 comprises a ball which is pressed on to a seat by a screw-threaded plunger which is manually adjustable. The pump, Fig. 3, comprises a piston 10 having internal passageways communicating with the outlet pipe 23 and the entrance to which passageways are closed on the upstroke of the piston by a ball valve 17 and below the piston ball valve 38 which closes the inlet 20 to the pump cylinder on the downstroke of the piston.

Abstract: 544,537. Photo-electric safety apparatus for electric circuits. BRITISH THOMSON-HOUSTON CO., Ltd. May 21, 1941, No. 6501. Convention date, May 21, 1940. [Classes 39 (i) and 40 (iii)] For protecting electric circuits such as switch gears of central stations, a photo-electric apparatus is used in which the photo-electric sensitive device is of high sensitivity to. ultra-violet radiaton such as is produced by an arc fault and of low or negligible sensitivity to medium intensity daylight and conventional artificial illumination. This enables the apparatus to be constructed without light screening except from direct sun light. A suitable photo-electric cell is one comprising a sodium cathode in an ultra-violet transmitting envelope. As shown in Fig. 1, such photo-electric cells 13 are arranged in the compartments of a metal-clad type of switch gear in such positions that at least one and preferably two photo-electric cells are affected by radiation from any arcing likely to occur in the compartments, which include busbars 4 in one compartment and branch circuit connections 5 and transformer 11 in another compartment divided from the first by a partition 10. When a photoelectric cell is affected by the radiation, an amplifier-relay device 131 is actuated and operates a switch device 22 which in turn actuates a mechanism 12 causing the circuit breaker 2 to depress hollow insulators 6 thereby disconnecting the circuit 5 from the busbars. In other arrangements, sections of the busbars may be disconnected as well or instead of the branch circuit 5. Fig. 3 (not shown) shows the invention applied to an open-type indoor switchgear.
