Title: Self priming liquid pump system
IPC: F04D9/00
Filed: 1967-11-14
Abstract: 1,212,378. Centrifugal pumps. WORTHING- TON CORP. Nov.14, 1967 [April 18, 1967], No.51732/67. Heading F1C. [Also in Division F2] A self-priming pumping system has a centrifugal pump 12, Fig. 1, arranged inside a well 14 as shown or externally of a liquid storage tank (224), Fig. 7 (not shown), to draw liquid from the well or tank and discharge it through a line containing a liquid accumulator 22. Should the pump lose its prime, a by-pass valve 74 (see Division F2) is opened to permit liquid to pass from the accumulator down into the well to re-prime the pump and expel air or vapour from the well through a line 68 containing a non-return valve 70. The valve 74 may be controlled automatically by the liquid pressure in the accumulator either directly or through a fluid servomotor system, Fig. 4 (not shown). The valve may additionally be associated with an external pressure by which it can be manually or automatically controlled. The valve may be actuated by a solenoid energized through a switch controlled by the liquid pressure in the accumulator, Fig.5 (not shown), or by the liquid level in the well, Fig. 6 (not shown). The switch may be selectively by-passed to provide remote control of the solenoid.

Title: A rolling mill
IPC: B21B13/06
Filed: 1966-11-18
Abstract: 1,126,656. Rolling. E. W. BLISS CO. 18 Nov., 1966 [6 Jan., 1966], No. 51739/66. Heading B3M. A rolling mill, such as a strip edg ng mill, comprising a pair of vertical rolls 20, 22 for sizing a workpiece B, includes, for each roll, a removable housing 12 which supports the roll necks in bearings 24, 26, couplings being provided between the housing and a fixed base 10 for supplying lubricant and coolant to the bearings. Each coupling includes a nipple 110 attached to the housing and a corresponding extendible nipple 130 on the base 10. When the housing is fixed in position relative to the base, the nipples 130 are raised by fluid pressure under the control of a slide valve 230, mating of the nipples automatically permitting lubricant and coolant to flow to the bearings. The lubricant is supplied from a reservoir 270 and passes through conduits 272, the corresponding nipp'es 130, further conduits 50 and 60, and to annular spaces 54 and 64 surrounding the bearings. Conduits 52, 62, and 274 return the lubricant to the reservoir. The flow of lubricant is maintained for a short period after the housing has been changed, the valve 230 then being moved to retract the nipples 130. The coolant is supplied continuously during rolling and passes from a supply to a coupling 280, through conduit 76 to chambers 70 and 72, and then through a conduit 82 to an outlet 282 or a further coupling. The couplings can be operated in each case by the supply of lubricant or coolant, the need for a separate operating fluid thus being obviated. In this latter case, fluid is pumped beneath a piston 302, Fig. 3, to raise a hollow rod 304 and an attached nipple 130. Coupling between the nipple 130 and the nipple 110 automatically unseats both a spring-loaded ball 116 and a spring-loader plunger 136 to communicate the passages 132 and 50. Uncoupling of the nipples by supplying fluid to the space above the piston 302, closes the valves in the nipples.

A fastening device for securing a lid to a container comprises a spring keeper f adapted to be secured to the container and a hook bolt b adapted to be pivoted to the lid so that the bolt can be engaged with the keeper without pivoting but which must be pivoted through an arc to become disengaged from the keeper. In the construction shown the keeper is disposed on the inside of the container so that a portion projects at an angle to the container wall and the bolt is pivoted to a bracket d integral with the lid of the container and near one end of the lid. The bolt is pivoted by a key having a square section shank which passes through a hole in the container wall. The opposite end of the lid is held in place by integral studs which project from its end edge and engage apertures in the corresponding wall of the container. Instead of the bracket being integral with the lid, a separate bracket can be provided where the device is to be used with containers and lids made of wood.

Abstract: 1364509 Drying or cooling powder or granular materials BUSS AG 12 Nov 1971 [16 Nov 1970] 52612/71 Headings F4G and F4U Dusty, powdery or granular material is continuously dried or cooled by passing it suspended in a gas stream through a tangential inlet 7 into a cylindrical treatment chamber 1 having a cylindrical outlet chamber 6 from which gas and dried material is withdrawn via tangential outlet 8. Heavy (i.e. wetter and larger) particles assume the largest-radius orbit possible and hence have longer residence times in the treatment chamber 1 than light particles. The incoming wet particles progressively displace the drying particles towards the centre where the radial gas flow entrains them for discharge at 8. The cover 4 is screwed to the wall 2 of the chamber 1 for easy dismantling for cleaning, the wear plate 3 is a replaceable insert, and the wall 2 is protected by a replaceable liner (not shown). An upward extension 9 of the container 6 shields the inlet 7. Air inlets may be provided near the inlet 7 and baffles at the lower end of the chamber 1 for directing particles inwards, and the chamber 1 may be surrounded with a heating or cooling jacket. The dryer may be followed by a cyclone, or by a similar dryer in series.

The reduction in pressure used to suck the yarn into the guide tube may thus be equal to or less than that used to extract pollutants. In the embodiment of Fig. 1 when suction unit 12 is applied to the unheated tulbe 6 its weight pivots the tube so that its end 5 comes into air-tight contact with the annular end face 7 of the 'connector 3 to block off extraction opening 110. In Fig. 4 unheated guide tube 29 terminates in cylindrical housing 30 having a tube socket 31 connected via flexible hose to a vapour extraction system. In the yarn threading position shown flange 34 on the end of heated guide tube 2 abuts the bottom of housing 30 to seal off access to the extraction system.
