Abstract: 813,234. Hydrodynamic torque converters; fluid-pressure servomotor control systems. GENERAL MOTORS CORPORATION. July 12, 1957 [Aug. 6, 1956], No. 22140/57. Classes 69 (2) and 135. A turbo converter comprises an impeller having radially disposed fixed blades 53 and pivoted blades 56 at the outlet side of the fixed blades. There are twice as many blades 56 as fixed blades 53, and they are adjustable from a forward angle, giving the impeller a inaximum capacity, to an extreme backward position in which the blades 56 completely block the output from the fixed blades. The converter also includes a turbine 78 fast with an output shaft 24 and reaction members 84, 86 mounted by one-way clutches on a stationary shaft 28. The blades 56 are adjusted by a servomotor controlled by an output driven governor. Each blade 56 is fixed to a crankshaft 57 engaging a groove in a common actuator ring 73 which is secured by rods 76 to a servomotor piston 39. Piston 39 is disposed in an annular chamber formed at the rear of the impeller, and divides the chamber into a pressure chamber 37 and a chamber connected to the working circuit. The piston is urged to the right by springs 46, 48; a central port 41 and a relief valve 40 are provided in the piston. A control sleeve 108 is slidable axially by an output driven governor 96 to vary the effective size of port 41. An input driven pump 35 supplies liquid through a passage 94 to chamber 37, and piston 39 takes up a position relative to sleeve 108 in which port 41 is sufficiently open to provide a pressure differential balancing the force of springs 46, 48. The angle of blades 56 is thereby adjusted to give a constant output speed. Cooling fins 31 are provided on the impeller casing, the driving engine having a fan which blows air through a duct 121 over the fins and out through an aperture 123 in a stationary housing.

Title: An improved die assembly for cutting sheets from a continuous web
IPC: G03D15/04
Filed: 1958-07-16
Abstract: 824,638. Cutting webs. KODAK Ltd. July 16, 1958 [July 18, 1957], No. 22845/58. Class 31 (1). A die assembly for cutting sheets, e.g. photographic prints, from a continuous web comprises die members 24, 25 fixed to a stationary support 20 across which a web W is adapted to be advanced intermittently from a supply roll 10 by means of rollers 11, 12 a punch 49 which is mounted on a hinged carrier 35 for movement towards and away from the support 20 in synchronism with the intermittent advance of the web and, when the web is stationary, co-operates with the die members to cut a sheet from the end of the web, a sheetejecting roller 57 which is moved into contact with the portion of the web to be cut-off as the punch carrier 35 is lowered and is moved out of the path of movement of the web as the punch carrier is raised, the roller 57 having a friction surface which resists relative motion between the roller and the web when they are in contact, and a spring 60 which is tensioned, after the roller 57 has come into contact with the web, during the lowering of the punch carrier and rotates the roller 57 to eject a sheet from the assembly as soon as the sheet has been cut off the web. The roller 57 is freely mounted on a shaft 56, Fig. 5, which is rotatably mounted on a U-shaped bracket 54 pivotally connected to a stationary plate 51, and the spring 60 has one end secured to the roller 57 and the other end secured to a collar 62 fixed to the shaft 56. A gear segment 58, Fig. 4, secured to the punch carrier meshes with a pinion 59 fixed to one end of the shaft 56, thereby holding the roller 57 off the web when the punch carrier is in its upward position. When the punch carrier starts its downward movement, the roller 57 engages the sheet to be cut off. The sheet prevents the roller from turning so that continued downward movement of the punch carrier causes the gear segment 58 to rotate the pinion 59 with respect to the roller 57 thereby winding the spring 60. As soon as the sheet is cut off, the roller 57 turns under the action of the spring 60 and ejects the cut-off sheet. A roller 29, Fig. 4, is provided beneath the roller 57 to reduce friction opposing ejection of the cut-off sheet. When the punch carrier starts its upward movement, the gear segment 58 rotates the roller 57 until a pin 65, Fig. 5, engages one arm of the bracket 54. The gear segment then lifts the entire roller assembly 55 from the web thus providing clearance for the next web advance. The extreme upward movement of the roller assembly is limited by a stop lug 70 extending into the path of the other arm of the bracket 54. A pin 73, Fig. 5, extending from the roller 57 co-operates with a cutaway roller 71 to limit the rotation of the roller 57.

Abstract: 355,911. Optical interferometers. WILLIAMS, W. E., Kildare, Ethelbert Road, Bromley, Kent. July 29, 1930, No. 22886. [Class 97 (i).] In an interferometer employing divisions of the wavefront of the primary light source to produce a number of parallel beams, one of the beams is laterally displaced either once or twice relatively to the next in order to increase the brightness of the interference fringes. In the form shown two beams are derived from contiguous parts of a single beam passing through a vertical slit in a screen 12 after traversing a narrow vertical aperture 10 in a collimator screen, and an achromatic lens 11. The beam is divided into two by two Albrecht rhombs 13, 14, or equivalent optical devices, which also displace the separated beams laterally and then direct them along parallel paths in which are placed the gas chambers 15, 16 and compensating plates (not shown). The beams are re-united by rhombs &c. 17, 18 and pass through the lens 19 of a telescope having a cylindrical eyepiece 20. The interferometer may be used in conj unction with a spectroscope for direct observation of the fringes, the eyepiece 20 being in this case dispensed with, and the fringes focused directly on the vertical slit of the spectroscope.

Classes 142(i) and 142(iv), [Also in Group VIII] A stop motion for a warp of yarns comprises a roller 5 on which a tape 9 is wound as an open helix, the outer surface of the tape 9 being adhesive so that a slack of broken yarn of the warp passing over the roller contacts and adheres to the tape thereby restricting rotation of the roller and causing electrical contacts to engage to effect stoppage of the machine. The roller 5 is mounted on bearings one of which is formed on the end of a stub shaft 70 which carries a disc of insulating material 15 carrying pins 20, 21, 22. The pin 20 is an electrical contact connected to a ring 17 on the opposite side of the disc and which is contacted by the bush 18. The pin 21 is a stop for an arm 23 secured to the roller and passing between the pins 20, 21, the arm being held in contact with the pin 21 by a spring 24 secured to it and to the pin 22. The shaft 7 is rotated bv a pulley 13, its rotary motion being transmitted to the roller 5 by the spring 24 the direction of motion being such that the pin 21 is in advance of the arm 23. Should a yarn contact the tape 9 on the roller 5, the roller is retarded by the pull of the yarn and the arm 23 moves to contact the pin 20 completing an electrical circuit and thereby stopping the machine.
