Title: Improvements in or relating to moving display receptacles
IPC: A47F3/08
Filed: 1930-08-30
Abstract: 361,014. Displaying. KILEMNIK, M., 524, Florida, Buenos Ayres. Aug. 30, 1930, No. 25975. [Class 3 (i).] Apparatus for bringing a number of receptacles V in succession to a display window E comprises upper and lower rails R<1>, R, lifting and lowering mechanisms M, and pivoted members Br, Br<1> which respectively transfer the receptacles from the lifting members to the upper rails, and from the upper rails to the lowering members. The mechanisms M consist of a motor connected to a platform PL sliding between guides G. The platform PL attaches itself to a receptacle V either by magnetism or by spring or counterweighted hooks. The members Br, Br<1> carry motors which move them from vertical to horizontal position and vice versa, the motors being started and stopped by various contacts engaged by the receptacles. The receptacles run along the rails R<1> R either by gravity or by an endless chain or by motors, the motors being stopped by contacts on the receptacles when these meet an obstruction. In a modification one transfer member Br only is provided, being located above the level of the upper rails R<1>, and the receptacles have bottom wheels running on the rails R, R<1>. Platforms raise and lower the receptacles. Fig. 5 shows a further form in which a truck Cz, running on rails, slidingly engages a receptacle V when it has reached its upper display position, and shunts it along its rails R<1> to the descent platform.

Abstract: 675,929. Beam warping and beaming machines. REINERS, W. Oct. 30, 1950 [July 26, 1949], No. 26469/50. Class 142(iv) A beam 23, after passing a dead-centre position 29 during swinging about its pivot 26 towards its driving roller 25, keeps friction driving wheels 3 and 4 in contact due to its torque about the pivot 29 tending to move the shaft 6 in the direction of the arrow. The beam is swung in about its pivot by a quadrant 20, gear 19, worm and worm wheel 16, 17, shaft 6, friction drive 3, 4 and motor 2. A hand lever 15 moves the shaft to bring the wheel 5 against the wheel 3 to swing the beam outwards. The lever is also used to keep the appropriate friction wheels in engagement during the upward movement of the beam to its deadcentre position. When the beam is swung away from its driving roller and has passed its dead-centre position, the weight of the beam moves the shaft 6 in the opposite direction and keeps the wheels 3, 5 in engagement.

Title: Improvements in or relating to control systems for synchronous machines
IPC: H02K19/10
Filed: 1956-09-03
Abstract: 803,957. Control of A.C. motors. BRONIEWSKI, B. Sept. 3, 1956 [Sept. 2, 1955], No. 26915/56. Class 38 (3). A three-phase synchronous machine which may operate as a generator or a motor has its stator winding S connected to a bridge PI, comprising thyratrons a-f, which permits the transfer of energy from the stator to the supply system Ra or in the opposite direction. The bridge PI is connected to a direct-current source consisting of a second bridge PII which is, in turn, connected to the supply system Ra. The control of the bridge PI is effected at the frequency of the stator current, whilst the control of the bridge PII takes place at the frequency of the supply, this control consisting in varying the firing periods of the valves by phase-shifting the grid voltages. In this manner, the amplitude of the stator current and is phase-relationship with the stator voltage s regulated. The machine may be started as a motor by allowing the passage of current through only two phases of the stator winding, by blocking some of the controlled rectifiers. During the starting period, the current in the bridge PII is intermittently interrupted at a frequency which is a multiple of the motor speed. When the motor reaches a predetermined speed, the voltage induced in the motor becomes sufficient to ensure commutation so that the intermittent current flow imposed on the valves of the bridge PII is removed. An inductance L reduces the ripple current.

Abstract: 615,733. Bobbins. OWENS - CORNING FIBERGLAS CORPORATION. Oct. 18, 1945, No. 27424. Convention date, Feb. 14. [Class 120(iii)] [Also in Group XXIII] In the production and packaging of fibres of heat softenable material, particularly glass, the material is attentuated to fibres by winding on a rotary member surrounded by a flexible sleeve, which may ultimately be collapsed for removal from the package, but which, during the winding, is subjected to an outwardly expanding force to enable it to resist the tension of the winding process. The flexible sleeve 19 of the winding device shown is supported on the outer rounded edges of blades 36, pivoted at 37 in end plates 32 having slots 34 whose leading sides 40 limit the force centrifugally applied by the blades to the sleeve as the device is rotated on its spindle 17. The sleeve may be made of gummed or latex-coated paper, or cotton or glass fibre cloth treated or coated with the material known under the Registered Trade Mark "Vinylite," or rubber coated cloth. Glass fibres, attenuated by the pull of the winding device from molten glass streams issuing from the multi-orificed. bottom of a feeder, may be gathered into a strand (a lubricant and binder being applied), and the strand fed onto the sleeve 19 by a traversing mechanism comprising an eye mounted on a slide reciprocated longitudinally by a drum-type cam. For further processing of the package, the collapsable sleeve 19 may be removed from its interior before or after transport, and the fibres may be unwound from the inside, or, if wound with a slow traverse, may be withdrawn from the end as an annulus (Fig. 4, not shown).

Stays.-The hinged lid of a cabinet, box, or other article is held in the open position by a stay c which co-operates with two gravity-controller members, the member k deflecting the end of the stav into engagement with the member j as the lid is being raised; further raising of the lid releases the stay end from the catch j, when the lid is free to be closed. The stay is hinged at c<1> to the lid b and its lower end is guided in a slotted member g secured to the receptacle a, a pin i limiting the upward movement of the lid. The hinged member k engages with a hook e on the end of the stay when the lid is raised and then deflects the stay in its upward movement so that the extension f engages with the pivoted catch j. The lid is then held in the open position and the member k falls back into its initial position. On raising the lid further, the stay moves away by gravity from the catch and the lid may then close freely.
