Title: Arrangement for automatically controlling the torque of  a winch
IPC: H02P29/40
Filed: 1971-04-19
Abstract: 1347116 Automatic torque control LICENTIA PATENT-VERWALTUNGS GmbH 19 April 1971 [15 April 1970] 26804/71 Heading G3R The torque of a braked winch is measured and automatically regulated to a predetermined value by actuating a winch motor in response to torque variations.  In Fig. 1, a rope mooring a ship to a quay is wound on the drum 8 of a ships winch driven through gearing 3 by a motor 1 which is normally held in a fixed position by a disc brake 4 engaging shoes 9 supported relative to the ship at 10. A signal corresponding to the torque applied to support 10 by the mooring rope is produced by a hydraulic, quartz or magnetic transducer 11 and compared with a signal representing desired torque so that errors exceeding a desired value cause operation of a transistor circuit to release brake 5 and actuate motor 1 to reduce the error. The drive for motor 1 is derived by way of a servo unit from the desired torque signal, and actuation continues until the motor speed reaches zero. After a time delay, the brake is re-applied and the motor switched off. Thus the torque is again monitored by sensor 11.

Title: Improvements in blade assemblies for gas turbines and the like
IPC: F01D9/04
Filed: 1952-10-29
Abstract: 727,608. Turbines. GENERAL MOTORS CORPORATION. Oct. 29, 1952 [Oct. 31, 1951], No. 27138/52. Class 110 (3). A stator ring for a gas turbine or compressor consisting of an inner and outer shroud ring with a plurality of blades removably supported between them has the inner ring formed in a number of arcuate segments which are slidable into engagement with one another, the engagement being such as to prevent relative axial movement between adjacent segments. The term " removably supported " is used to mean that the blades are separate members from the shroud rings. The stator ring 10 mounted in a casing 11, is formed by a pair of semicircular segments 12. Each of the segments consists of an outer shroud ring 13 and an inner shroud ring 14 between which are mounted the stator races 16. Each of the inner shroud ring segments comprises a pair of channel members 18, 20 which are secured to one another by spot welding. The flanges 24, 30, 32 and 26 form with the adjacent surfaces of the rotor disc, a seal for the inner ends of the vanes 16. The webs of the channel members are pierced to receive the tenons 48 of the stator vanes. The segments 12 of the stator ring are interconnected by tongue-and-groove connections integrally formed at both ends of the inner shroud ring elements 14. The inner channel member 20 projects beyond the ends of the flanges 24, 26 of the outer channel member 18 and has a slot 54 formed in the web 28. This slot receives a tongue 56 formed in the web 28 of the channel member 20 of the other inner shroud ring. The outer channel member 18 of the other shroud band 14 extends beyond the flanges 30, 32 of the inner channel member 20 and has a groove or slot 58 adapted to receive a tongue 60 formed in the web 22 of the outer channel member 18 of the first shroud band 14. The separation X, Y between the ends of inner and outer channel members allows for circumferential expansion. The clearances between the tongue and the groove prevents binding and aids assembly. The entering edges of the tongue and groove may be chamfered or curled in opposite directions to facilitate assembly. The outer shroud bands 13 have flanges 34, 36 which engage an annular groove 38 in the inner surface of the casing to which they are attached by stud bolts 44. The vanes 16 are attached to the shroud bands 13 by tenons 46 which are beaded over the ring. In a modification, the tongues at the ends of the channel members are formed by notching the web and forcing the flanges inwards and the slots by cutting away the web of the channel member and forcing the flanges outwards. In a further modification, the tongue is formed by bending the web 28 and flanges 30, 32 inwardly so as to fit the unmodified end of the inner channel member of the adjacent section. In other modifications, a separate tongue or tongues are welded to the end of one channel member to engage the unmodified end of the inner channel member of the adjacent section or the spacers between the flanges of the channel members.

Title: Improvements in starting electric luminous discharge lamps and tungsten arc lamps
IPC: H01J61/54
Filed: 1923-10-31
Abstract: 215,312. General Electric Co., Ltd., (Assignees of Patent-Treuhand-Ges.-f³r Elektrische Gl³hlampen). May 4, 1923, [Convention date]. Vacuum tubes; arc lamps; arc-lamp electrodes. -In a lamp filled with rare gas in which a glow is either maintained continuously or serves for starting the lamp, the starting-voltage is reduced by covering the insulator between the electrodes with a very thin layer of material of low conductivity. The layer may consist of metallic or non-maballic substances and may be placed on the foot-tube of the lamp or on a special carrier of insulating-material positioned between the electrodes or leading-in wires. A metal layer may be deposited by cathodic sputtering with alternating current in the presence of hydrogen, or by being dipped into, or painted with, a solution or paste containing the metal. The layer may consist of graphite, or of a material which reduoesthe cathode drop, such as an alkaline earth metal prepared for example, by decomposing a layer ofbarium nitride. Fig. 1 shows a glow-dischargelamp having hood-shaped electrodes b carried on a stem d attached to the foot-tube c. Between the leading-in wires e is the thin layer f of low conductivity material which acts as a bridge between the leading-in wires e and may extend partly up them. When the current is switched on, this layer becomes covered with glow, which remains while the lamp is burning, and which facilitates the formation of glow on the cathode. The gas pressure may be 10 to 20 mm. for ordinary supply voltages. Fig. 2 shows a tungsten are lamp in which a similar layer f is arranged on the foot-tube c, bridging the electrode leads e. A glow discharge occurs at starting on the layer f ionizes the gas between the tungsten electrodesb, and starts the arc. The ensuing fall of voltage then causes the glow on the layer f to disappear. The leads e may be of iron or othermetal of comparatively low melting-point. Specifications 17036/14 and 17646/14 are referred to-
