Abstract: 699,000. Measuring thickness by radio-active emanations. WUPPERMANN, A. T. Aug. 16, 1951 (Aug. 16, 1950; March 14, 1951], No. 19374/51. Class 40 (iii). Apparatus for comparing the thickness of a sheet of material 6 with that of a standard 5 by the use of X-rays or other radio-active emanations is characterized by the automatic introduction of a plate of standard thickness into the relevant pencil of rays when the measured sheet 6 is absent, thereby protecting the measuring tubes against excess exposure, and affording an opportunity of adjusting the measuring circuit. As shown in Fig. 1, an X-ray tube 1 produces two pencils of rays 7, 8 through holes in a screening plate 4, one passing through a standard plate 5 to a Geiger-Muller tube 2, and the other passing through the measured plate 6 to another tube 3. When the measured plate 6 is absent a relay 9 and spring 10 cause the standard plate 5 to cut both pencils of rays 7, 8. In another embodiment (not shown) the two pencils of rays are emitted at right-angles to minimize inaccuracies due to secondary emission, and a separate standard plate takes the place of the measured sheet when the latter is absent. The apparatus is preferably kept under pressure in gas-filled containers with special cooling arrangements.

Filed: 1954-07-02
Abstract: 748,328. Attaching continuously delivered yarn to winding means. CELANESE CORPORATION OF AMERICA. July 2, 1954 [July 3, 1953], No. 19450/54. Class 120 (2). In order to facilitate the throwing of continuously delivered yarn on to a bobbin in a ring twisting machine without a long loose tail extending from the yarn package, a yarn guide is provided in combination with severing means to cause yarn extending from the ring traveller to be wound on to the bobbin and the end severed by a movement of the guide. On removal of a full bobbin, the yarn is passed from the feed roll 26 to a balloon guide 29, thence to an upper guide 34 and back to the feed roll 26. After an empty bobbin 12 has been placed on the spindle, the yarn extending between the guides 29, 34 is manually drawn through the ring 17, engaged in the traveller 21 and passed under guides 32, 33, the bobbin 12 being kept stationary during this operation by a spindle brake. When the brake is released and as the ring rail 19 moves towards the bottom of its traverse, an arm 46 is moved either manually or automatically to turn the guide 32 towards the bobbin 12 thereby causing the yarn to engage the edge of the lower flange 14 of the bobbin. The yarn is caught in a slot 15 and begins to wind on the bobbin 12. At the same time, movement of the arm 46 causes a sleeve 66 to move along a rod 56 to trap the yarn between the sleeve 66 and a head 57 at the end of the rod, thus severing the yarn.

Title: Improvements in and relating to dynamo-electric machines
Inventor: LAW HILTON
IPC: H02K13/14
Filed: 1957-06-20
Abstract: 889,971. Improving commutation and current collection in dynamo - electric machines. ENGLISH ELECTRIC CO. Ltd. June 20, 1958 [June 20, 1957], No. 19487/57. Class 35. Deterioration of slip-ring and commutator brush contacts in machines subject to long periods of idle running, is prevented by the injection of circulating alternating current between pairs of brushes of the same polarity so as to provide the necessary minimum current loading. As shown for a D.C. commutator machine, the brushes are connected in pairs 12a, 12b and 13a, 13b by centre-tapped chokes 14, 19 respectively. These chokes allow the passage of the D.C. load current but offer a high impedance to the circulating current injected by transformer 18. If desired, the circulating current may be reduced on load by a regulator 24 responsive to the voltage across a shunt 25 in the load circuit, although it is stated that saturation of the chokes by the load current also produces this effect. The invention may be applied to split brushes by causing current to circulate between the two brush parts, and it may similarly be applied to multipolar machines having several e.g. two, positive and negative brushes to produce circulating current between brushes of the same polarity but different circumferential position. The invention may be applied to A.C. machines, e.g. by circulating current of higher frequency than that of the load current.
