Patent GB-284586-A (GB)
IPC: H01H3/34
Filed: 1928-01-30
Abstract: 284,586. Riviere, M. P. R., and Soc. Anon. des Anciens Etablissements d'Appareillage Electrique Gabreau. Jan. 29, 1927, [Convention date]. No Patent granted (Sealing fee not paid). Speed-indicator transmission mechanism. - Comprises an electrically controlled ratchet device for imparting a step-by-step movement in one or both directions to a rotary member; stated to be applicable for the distant control of speedometers &c. A toothed disc B secured to a shaft A or other rotary member to be actuated, is normally locked by a pair of oppositely acting pawls D, D<1> carried by arms C, C<1> freely pivoted about the shaft axis and drawn together by a preferably adjustable spring G, or by a torsion spring concentric with the shaft. The arms are respectively connected by links J, J' to pivoted or slidable armatures K, K<1> normally drawn back against stops N, N<1> under the influence of the spring G. When one of the electromagnets L is energized, the corresponding arm C is drawn down with the armature K, the pawl D slipping over the tooth into the next notch. Simultaneously, a link S' pivoted to the arm C rocks an arm P<1> on a fixed pivot O<1> to raise the idle retaining pawl D<1> out of action by impact with a tail piece R<1> thereon. When the electromagnet is de-energized, the arm C is returned by the spring G, carrying the toothed wheel B forward one step. A similar movement in the opposite direction is obtained through the arm C<1> and pawl D<1>, by sending an impulse through the electromagnet L<1>. The member B may be wholly or partially toothed and adapted to receive a stepby-step movement through a limited angle or through complete rotations. When the movement is through a limited arc, a safety switch controlled by the shaft A may be provided to open the circuit of the electromagnet when the limit position is reached. One of the electromagnets may be eliminated and the corresponding arm C or C' fixed, when rotation in one direction only is required. The device may work at high speed and limitations thereto may be set by selection of the masses of the moving parts and regulation of the strengths of the spring and electromagnets. With a sufficiently strong spring, the upper speed limit corresponding to the full stroke of the pawl may be exceeded, the pawl imparting impulses to the wheel and returning before completing its full stroke. By the introduction of a make-andbreak switch, as shown in Fig. 3, into the electromagnet circuit, a continuous series of impulses may be transmitted for so long as the switch : i is closed.

Abstract: 267,479. Deutsche Spinnereimaschinenbau Akt.-Ges. March 15, 1926, [Convention date]. Void [Published under Sect. 91 of the Acts]. Guards, controlling.-In guards for carding- engines, the rod controlling the opening and closing of the stripper door is locked not only by means on the belt-fork but also by co-operation with means frictionally controlled by motion of the fast pulley. A rod h, having an enlarged part i guided in a slidable sleeve k, is rigid with a rod f jointed to the pivoted arm d' carrying the stripper door b. A spring l normally holds the sleeve k against a collar h<1> on the rod h, in which position registering notches n in the parts k, i can be engaged by a pin o on an extension p of the belt-fork q when this is over the fast pulley w. On shifting the belt, the pin o is withdrawn, but movement of the sleeve k to the right brings a pivoted sector s thereon, Figs. 2 and 3, into frictional contact with a flange v on the pulley w, rotation of which turns the sector against its counterweight t, as shown in Fig. 3, to bring a projection u into the path of the rod h. When the pulley stops, the weight t lifts the sector s, allowing the rod h to move to the right and open the door, the spring l being compressed. In a modification, rollers k<2>, Fig. 5, press a bar x against the pulley flange v, rotation of which depresses the bar against a spring y and moves a hole x<1> out of line with the rod h.

Title: A method of and apparatus for obtaining tempered glass sheets
IPC: G03B19/10
Filed: 1938-02-04
Abstract: 503,649. Glass manufacture; tempering glass. FERLITO, E. Feb. 4, 1938, No. 3633. Convention date, Dec. 24, 1937. [Class 56] Relates to the production of tempered glass sheets which can be divided into smaller portions. According to the invention, grooves or indentations are formed in the glass sheet during or immediately after manufacture, while the glass is still hot and plastic, and the grooved sheet is tempered immediately by passing it between air blowers. The tempered sheet may be divided by cutting along the grooves. A sheet c, Fig. 1, can be formed by a drawing- apparatus of known type, and while the glass is still plastic, the sheet passes between rollers e, .f, one or both of which are provided with projecting ribs or blades that impress grooves in the glass. The hot glass is chilled by air blasts from nozzles or slots fitted to or formed in hollow rollers g which are connected to suitable fans. The sheet is also cooled by two large hollow rollers h provided with nozzles and connected to suction devices, so that hot air is drawn away from the surface of the glass. In another construction, the glass is grooved by dies t, Fig. 8, which are moved to and from the glass either mechanically or by pneumatic or hydraulic cylinders o. These cylinders are supported on the pistons of hydraulic or pneumatic cylinders m, and admission and exhaust of the power fluid of the cylinders m is so timed that the dies t move with the glass during the impressing period. Finally, the sheet passes between blowers u from which jets of air are blown on to the glass. The method may be carried out also with a drawing- apparatus of the Libbey-Owens type, the sheet being impressed, after passing over the bending- roller, by blades moved to and from the glass. The grooved sheet may also be formed by pouring glass on to a casting-table or mould which is formed with protuberances corresponding to the desired grooves, and a roller also formed with ribs or blades is then passed over the glass. The plate so formed may be chilled while on the table, or it may be conveyed to a blowing-apparatus. The grooves may also be formed by grids or gratings w, x, Fig. 10, and the glass plate z may be chilled while still on the casting-table v after the grid x has been removed, the presence of the grid w modifiying the tempering of the glass in the grooves.
