Abstract: 1,213,992. Jet Loom. MACHINEFABRIEK L TE STRAKE. 26 Sept., 1968 [26 Sept., 1967], No. 43870/67. Heading D1E. The leading end of a weft thread inserted by a jet of fluid has its weight increased by wetting it; the heavy leading end is propelled by a short spurt of water or steam, and the remainder of the length of weft may be acted on by a jet of air. Nozzle. Water entering a chamber 16 by a pipe 21 is converted into steam by an electrical heater 26. The steam pressure opens a valve 17 by moving the core 12 to the left, whereupon the steam impinges on the leading end of the weft thread 1; part of the steam condenses on the thread, assisted by cooling gas entering a pipe 29, and the remainder acts as a propelling jet. The resulting drop in pressure allows a spring 22 to close the valve 17, thereby producing a jet of short duration. Alternatively, the valve 17 may be operated by a cam acting on a groove 30 on the core. An air jet can be supplied through the core 12. The heater 26 may be omitted.

Title: Improvements in or relating to television camera tubes
IPC: H01L27/00
Filed: 1960-12-21
Abstract: 942,406. Semi-conductor devices; television pick-up tubes. PHILIPS ELECTRICAL INDUSTRIES Ltd. Dec. 21, 1960 [Dec. 24, 1959], No. 43904/60. Headings H1D and H1K. The target of a television camera tube is composed of a mosaic of NPN semi-conductor elements, Fig. 2, the thickness of the P domains being smaller than the effective diffusion length of the minority carriers (electrons) in these regions. The base layer N is only interrupted at its front surface and is in contact with a signal electrode consisting of a thin transparent metal layer. The production of hole-electron pairs in the base layer by the radiation quanta falling upon produces an electron current through the semi-conductor proportional to the number of hole-electron pairs. The restoration of a mosaic element to cathode potential by the scanning beam produces an instantaneous voltage difference across the signal resistor. The target may be cooled to reduce the dark current. In Fig. 4 the tube incorporates a mirror optical system 12, the window 4 serving as a correction lens. A cooling vessel 11 is associated with the target. The mosaic elements of the target may be produced by etching N and P-type layers through a mask prepared by a photographic process or by depositing impurity atoms in the interstices of the mask from a flowing gas. The mask, e.g. silicon oxide, may be retained in position to protect the base layer from direct bombardment by the scanning beam. A suitable material for the base layer is silicon or germanium and the impurity atoms may be arsenic and boron or phosphorus and gallium.

A device for use in a work cylinder, e.g. for honing the interior annular sealing grooves of cylinders used with co-operating rams in mines such as advancing hydraulic cylinders and rams for mine roof supports, comprises a body 2 having radial tools 3, 4, 5 surfaced with honing material. The tool stems 3b, 4b, 5b are slidable in chambers 6, 7, 8 in the body fitted at their outer ends with bearing rings 9, 10, 11 retained by the edges of plates 18, 19 fastened by screws to the body. On the inner sides of the bearing rings are 0-rings 12, 13, 14. The inner ends of the tool stems carry piston rings 15, 16, 17 permitting limited flow of fluid past them. The diameter of the tool stems is less than that of the chambers thus forming annuli A1, A2, A3. Pressure fluid from an inlet connection 24 is supplied through passageways 25a-h in the body to the annuli. A return duct 26 extends past the inner ends of the chambers 6, 7, 8 and a valve 30 operable by a pivoted hand lever 32 is provided between the duct and an outlet connection 29. There may be an inlet connection 36 for coolant liquid which passes through passageways in the body similar to those for the pressure fluid to outlets 37, 38, 39 between the tools. The device is held rotationally stationary, e.g. in a lathe. The valve 30 is opened, to retract the tools. The tools are located opposite the grooves in the work cylinder, the valve 30 closed to project the tools owing to back pressure, and the work cylinder rotated. (For Figures see next page.)
