Title: A compressed air operated free-piston engine used as an oscillation generator, more particularly for apparatus for winning and/or loading coal or the like
IPC: F01B11/06
Filed: 1956-07-18
Abstract: 836,422. Compressed-air engines; valve gear. GEWERKSCHAFT EISENHUTTE WESTFALIA. July 18, 1956 [Aug. 1, 1955], No. 22272/56. Classes 122 (2) and 122 (3). A pneumatically operated free piston engine used as an oscillation generator comprises a piston 10, Fig. 1, which is cushioned at the end of each stroke by entrapped air in chamber 12, 13, and a slide valve 21 which is reciprocated by the pressure fluctuations in these chambers, which are sealed from the working chambers 14, 15 of the free piston 10. In the embodiment of Fig. 1 compressed air from a passage 23 passes around the slide valve 21 to an inlet 28 to the engine cylinder 11 and via passages 16, 17 and non-return valves 18, 19 in the piston 10 to the cushioning chambers 12, 13. Air is also admitted by a passage 26 to the working chamber 14 to move the piston to the right thus compressing air in the cushion chamber 13 as air is discharged from the opposite working chamber 15 through exhaust passages 27, 25, cushioning chamber 12 meanwhile remaining open to the supply air pressure. The pressure in chamber 13 moves the piston 29, and the slide valve 21 to the right until air is admitted to the opposite end of the cylinder 11 causing the piston 10 to reverse its movement and to compress air in the cushion chamber 12 and thus to actuate the slide valve 21 by the piston 30 to complete the cycle. In the embodiment of Fig. 2 the slide valve 21 is actuated by hydraulic means interposed between the air cushioning chambers 12, 13 and the valve-actuating pistons 29, 30. Free pistons 33, 34 may be inserted in the lines 32, 31, liquid losses being compensated from a reservoir 35 through non-return valves 36, 37; conduits 38, 39 allow excess liquid to be returned to the supply lines from the space below the pistons 33, 34 when the pressure in the respective chambers 12, 13 is low. Compressed air is supplied to these chambers through a conduit 28 and a regulator 40, formed by a spool valve 41, and an inlet 43 having a by-pass conduit 44. This regulator maintains the air supply to the chambers 12, 13 substantially constant and slightly below that of the supply line because of the throttling action of the valve 41. The desired frequency of oscillation of the piston 10 is achieved by controlling the quantity of air supplied through a throttling disc 45 the spring 46 of which holds the valve open against the pressure of a free piston 49 which is subjected to the pressure in the cushion chamber 13 through a non-return valve 47. An adjustable outlet 50 is provided to ensure that the piston 49 is constantly under the influence of the pressure in the air cushion chamber 13. Starting is facilitated by opening a valve 51 or 52 to atmosphere.

Dynamo - electric machine windings consisting of conductor bars each formed by mutually insulated transposed multiple strands 1 are insulated by a method which comprises fixing the bar in a clamping device, not shown, winding on to the bar a sheath 2 of insulating tape consisting of mica on a carrier tape, forming a tight - fitting cover 5 peripherally about the insulating tape, and then with a synthetic resin 3 impregnating from within the contents contained within the cover, the cover being impermeable to the resin. The bar may be of the Roebel-type for large generators, the strand insulation and the carrier tape may be of glass filament fabric, the resin may be a polyester, certain strands may be hollow, and the impregnation may be under vacuum. The cover 5 may be produced by dipping the bar in a resin bath, or winding on a second tape, possibly of elastic material, or shrinking on a hose; it may be electrically conductive and vacuum-tight, act as a slot lining and as a protection against glow discharge, and may partially dissolve in the synthetic resin. The impregnation may be effected after the winding has been located in the machine slot, not shown.

Abstract: 1,267,997. Detecting holes in a moving web. WIGGINS TEAPE RESEARCH & DEVELOPMENT Ltd. April 20, 1970 [May 2, 1969], No.22536/69. Heading G1A. An apparatus detecting holes in a moving web comprises a light source with a lens system directing parallel light on to the web and a detector positioned on the other side of the web at such a distance that it responds to holes in the web but not to light diffusing through the web. In an embodiment, Fig. 1, parallel light formed by a collimating lens 7 and a light source 3, passes through a slot 6b and is incident on a web 10. Light which has passed through any holes and light which has diffused through the web then passes through slot 6a and is incident on a photo-voltaic detector 8. The depth of the slot 6a is such that the intensity of the diffuse light falls off to such an extent that a mono-stable flip-flop counting circuit Fig. 4 (not shown) can be used to detect and record any holes present in the web. The electric circuit excludes signals below a certain predetermined strength, that is, it excludes any signals from the diffuse light which would cause a background or noise signal. The counting circuit includes a relay (23), Figs.3 and 4 (not shown) which in turn operates a counter (24). In further embodiments greater use of the active surface area of the detector 8 is achieved by inserting a converging lens between the web and detector, and by arranging the lens so that an image of the source covers all the active surface of the detector, or, alternatively, by inserting an optical fibre bundle between the web and the detector, the bundle being outwardly tapered towards the slot to provide an elongated row of fibre ends extending along the slot.
