Abstract: <PICT:0799379/IV (a)/1> <PICT:0799379/IV (a)/2> <PICT:0799379/IV (a)/3> Apparatus for securing and positively locating a spinning jet, for use in the production of artificial filaments by the wet spinning process, comprises a union, with an externally projecting radial flange, for connecting a spinning jet to a flexible resilient supply-pipe, and a holder, for accommodating the union, with a seating for the forward face and outer edge of the flange, the latter being held securely, when in the holder, by the resilience of the supply-pipe forcing the forward face of the flange against the face of the seating.  Preferably the holder has a longitudinal U-shaped channel for accommodating the union and an entry passage for the flange to its seating, preferably in the form of a pair of slots cut in the walls of the channel and inclined at a small angle to the plane of the seating.  The seating may enclose sufficient of the outer edge of the flange to prevent transverse movement of the jet. The holder may also serve to align a spinning tube, through which the freshly formed filaments pass, coaxially with the jet by means of a bracket attached at that end of it opposite to the channel for the union.  The longitudinal axes of the union, the jet and the spinning tube may be horizontal and the face of the seating vertical.  As shown in Fig. 1, a resilient flexible pipe 2 is connected at its submerged end to a jet 1 by a flanged union 4.  Jet 1 is held in a bath 5 of coagulating liquid 6 by a holder 7 mounted on a base 8.  A bracket 9 also mounted on base 8 has an aperture 10 lined with a resilient bush 11 into which is fitted the end of a glass tube 12, the latter being coaxially aligned with jet 1 so that freshly formed filaments 13 pass through tube 12 to a take-up device (not shown). Referring to Figs. 2 and 4 the holder 7 has two walls 14, 15 between which is cradled the jet union 4.  A seating 16 is cut into walls 14, 15 for a flange 17 of union 4 which is urged into position by the resilient nature of pipe 2.  The seating encloses more than 180 degrees of the circumference of the flange 17 so that, when the union 4 is in position, no transverse movement of the jet is possible.  To provide access for the flange 17 to the seating 16, a pair of lead-in slots 18, one in each wall 14, 15, are cut in a plane set at an angle to the plane of, and leading into, the seating 16.

Title: A device and a method for examining the surface of a body
IPC: G01B11/30
Filed: 1963-09-23
Abstract: 1,055,996. Inspecting surfaces photo-electrically. M. J. RICHARDS. Dec. 23, 1964 [Sept. 23, 1963], No. 37262/63. Heading G1A. The surface of a body is examined by aligning a part of the body along an axis, directing a beam on to the body at an acute angle to the axis, and investigating the pattern of light reflected the body in a plane transverse to the axis. A wire 25 under test passes through a chamber 20 where the two sides of it are illuminated through apertures 32, 33 by light sources 29, 28 respectively. Light reflected from the wire falls on annular photosensitive devices 26, 27 each comprising a plurality of sector-shaped selenium or other cells. The outputs of the cells are measured in sequence and may be displayed on a cathode-ray tube, and any deviation from a predetermined pattern of outputs indicates a defect in the wire. Different proportions of the outputs may be compared with one another or with a reference output, the arrangement being particularly useful when examining non-circular wires. Light which spills past the edges of the wire passes through apertures in screens 40 to fall on photo-sensitive sectors which may be used to provide a reference signal indicative of the light source intensity or, when connected differentially, to indicate if the wire has drooped. The light source is formed by the end of a light guide leading from a lamp, preferably of the tungsten type. The length of the light guides limits the divergence angle of the light beams incident upon the wire. To eliminate all blind spots, three source-photo-cells systems may be provided.

Title: Improved Multiple Pump Assembly
Inventor: WOCHNER JOSEPH J
IPC: F04B/
Filed: 1967-08-14
Abstract: 1,171,707. Rotary pumps. ALLISCHALMERS MFG. CO. Aug. 14, 1967, [Aug. 18, 1966], No.37262/67. Heading F1F. A pump assembly comprises two pumping units 13, 16 of different capacities and having externally meshing pumping gears driven by a common shaft 19, said units being furnished with a common inletpassage 21 and a common outlet-passage 26, and a branch passage 28 associated with the latter and the unit 16 being controlled by two valves 18, 31 in accordance with the pressure in the passage 26. The valve 31 is a non-return or check valve whereas the valve 18 when in an open condition permits fluid in the passage to return to the passage 21 by way of a by-pass passage 36, the latter valve being regulated by a pilot valve 41 having an actuator 42 associated therewith. During normal operation of the assembly, a spring-loaded valve member 59 in the valve 18 is held against a seat 63 by pressure communicated to the interior of said valve member from the passages 28, 36 through an orifice or bleed hole 57. When the pressure in the outletpassage 26 becomes excessive, a spring-loaded valve member 51 in the pilot valve 41 is raised and permits fluid to flow through lateral openings 50 in a carrier 45 for said valve member into the passage 21, throttling caused by the hole 57 being effective to reduce the pressure within the valve member 59 so that owing to a conic surface 58 thereon the latter is deflected away from the seat 63 by the pressure prevailing in the passage 36. To prevent the pilot valve closing until the pressure in the passage 26 is reduced to a predetermined value, a plunger 43 constituting the actuator aforesaid is raised by pressure in a chamber 46, which is communicated thereto through a passage 66 from a further branch-passage 27 associated with the pump 13 and the passage 26, the area of the lower most end 60 of the plunger being greater than the cross-sectional area of a bore 64 in a seating 52 for the valve member 51 to ensure that there is sufficient thrust to hold the latter in an open position until the pressure in the various passages 26, 27, 28, 36 falls by a substantial amount, thereby preventing cyclic opening and closing, or "hunting", of the valves 18, 41.
