Abstract: 895,174. Hydraulic torque converters. BORGWARNER CORPORATION. Sept. 8, 1958 [Sept. 24, 1957], No. 28795/58. Class 69 (2). An hydraulic torque converter comprises an impeller 10, turbine 11 and stator 12, the vanes 21 of the stator being constructed of a flexible material and flexibly and pivotally mounted on spaced axes 22, 23 adjacent the leading and trailing ends thereof. The vanes flex under the influence of the fluid leaving the turbine to change the direction of flow of the fluid in a forward direction when the fluid impinges on the forward facing sides of the vanes, and in a reverse direction when the fluid impinges on the reversely facing sides of the vanes, prior to the entry of the fluid into the impeller. The vanes, which may be of silicone rubber, fibre glass, leather, interwoven chain or other heatresistant and pliable material, are disposed between opposed flat surfaces 34, 35 on rings 24, 25 secured to a stationary shaft 26, the vanes being mounted on pins 22, 23 extending between the surfaces.

Abstract: 1,130,739. Transformers. SIEMENS A.G. 22 June, 1967 [23 June, 1966], No. 28969/67. Heading H1T. The invention relates to means for reducing the voltage across control units 1 used in the transformer tap-changing arrangement described in French Specification 1,310,923 in which the load current is switched from one to another of two load current carrying connections, movable between tappings, by using controllable semi-conductor rectifier means. Each of the rectifier means is controlled by a control unit 1 having its input connected across the other rectifier means. At low tap voltages with the load current connections connected to adjacent taps a relay (5, Fig. 2, not shown) connected between them is not energized and its contacts 22 are closed shorting resistance 21 in series with control unit 1. When the inter-tap voltage reaches a predetermined level contacts 22 are opened and voltage across unit 1 is reduced to the lower level desirable in the steady condition when unit 1 is conducting. A capacitor 24 and high ohmic resistor 25 act as a bridging means for contacts 22 to minimize the increase in response time of unit 1 which would otherwise occur.

Abstract: 1284451 Rolling; straightening CHELYABINSKY POLITEKHNICHESKY INSTITUT 10 Aug 1969 29255/69 Headings B3E and B3M A method of rolling or straightening a sheet metal article includes passing the article between a pair of rolls rotating at different peripheral speeds, the ratio of the speeds of the rolls being not less than the reduction ratio of the article during working, and the speed of the faster roll being equal to the delivery speed of the article. The article can either pass directly between a pair of rolls, Fig. 6, or can be wrapped around one or more rolls, Figs. 3, 5. A forward and back tension is applied to the article in each instance. The rolls 9 and 10, Fig. 6, are driven at different speeds by separate motors. The two groups 16 and 17 of tensioning rollers are driven through gearing from the respective motors driving the rolls 9 and 10. A screw down 13 adjusts the spacing of the rolls. When an article is continuously rolled between successive pairs of rolls, the peripheral speed of the faster roll in one pair is made equal to the speed of the slower roll in the next pair. Different surface finishes may be applied to the rolls of a pair in order to modify the frictional forces between the rolls and an article.
