Title: Retaining rings and method of making the same
IPC: F16B21/18
Filed: 1959-02-02
Abstract: 855,047. Making retaining rings; forging; curving. BLUTH, L. S. Feb. 2, 1959, No. 3571/59. Classes 83 (2) and 83 (4). [Also in Group XXV] A method of making a retaining ring or circlip comprises cutting a linear strip of metal, e.g. spring steel, to a length equal to the circumferential length of of the ring; bending the strip into a discontinuous circular blank; swaging said blank to form a band of reduced thickness along one edge thereof, said band increasing in width from the centre towards the open ends of the blank, and pressure-forming said band into a corrugated wall. The ring blank 110 is bent to discontinuous circular shape by three rollers 111, 113, 114, the centre roller 111 being driven. The formed ring is then swaged between dies 120, 121, to form the band of reduced thickness 125 in the ring. Excess material is removed from the swaged-blank by trimming dies 130, 131, having opposed shearing edges. Finally, the band of reduced thickness is corrugated in stamping dies (not shown), to form a ring, as shown in either Fig. 1 or 5, and of a cross-section as shown in Fig. 2. The thicker portion of ring may be tapered as at 66 (Fig. 11).

Filed: 1953-02-10
Abstract: <PICT:0740825/III/1> <PICT:0740825/III/2> <PICT:0740825/III/3> A film evaporator comprising a cylindrical or conical chamber surrounded by a jacket for heatingmedium, and a rotor which passes axially through the chamber and has blades for maintaining the liquid as a film on the interior wall of the chamber is characterised in that the evolved vapours flow downwards through the evaporation concurrently with the liquid being evaporated so that the vapours and the concentrate are both withdrawn from the lower end of the evaporator.  The invention eliminates the entrainment of liquid droplets in the vapours.  In Fig. 3, evaporator chamber 100 is surrounded by a jacket having an steam inlet 104 and an outlet 106, a deflector plate 110 being provided so that the steam does not impinge directly upon the top of the wall of chamber 100.  This wall 100 is made of thin metal, and is surrounded by stiffening ring 132 to provide structural rigidity. The rotor, which is driven by shaft 116 and is supported in bearing 156 comprises a central tube 120 and a plurality of radial blades 122 which extend nearly to the inner wall of chamber 100. Mounted on the upper end of the blades is a distributer ring 124 having an inner concave surface 126.  An inlet pipe 128 for the feed liquid passes through cover plate 114, and has an opening in alignment with a plurality of small orifices 130 in ring 124. The liquid passes through the orifices under the centifrugal action of the ring, and is distributed evenly around the interior of chamber 100.  The concentrate flows off the lower periphery of chamber 100 and is collected in annular trough 144; the concentrate is swept to outlet 148 by extension 150 of one of the rotor blades.  The vapour outlet 152 is attached to the inner rim of trough 144.  A spray pipe condenser 160 is disposed within outlet 148, the lower end of which may be connected to a source of slight vacuum.  If a high degree of concentration is required, several evaporators may be connected in series.  For large production capacity a plurality of evaporators, connected in parallel, is used, each evaporator having a diameter of 10 to 12 inches.  Figs. 6 and 7 show several evaporators 200 arranged concentrically around a separator 202 which is provided with a rotor and blades 230.  The evaporators are supported on a common base 204 and are provided with a common heating jacket 206; but each evaporator has its own liquid inlet 216 and its own rotor and blades 212.  All the evaporators open at their lower ends into a common concentrate collector 218 having an outlet 220.  The vapour leaving the lower ends of the evaporators is drawn upwardly through separator 202 to outlet 226, which leads to a source of vacuum.  The individual evaporators may alternatively be arranged in side-by-side relationship.  Eletrical or mechanical means may be provided to shut off the feed to any evaporator if the movement of its rotor is interrupted for any reason.  Specification 656,605 is referred to.

Abstract: 230,966. Cross, J. W., and Fawcett, J. Feb. 16, 1924. Fluid-actuated valves. - An accelerator for a dry-pipe valve system, in which the air pressure is adapted more quickly to open the differential valves, comprises two diaphragms f, g a piston valve i working in a chamber j, and an air valve k, all mounted on a spindle e held in its uppermost position by a spring e<2>. On charging the installation the air under pressure passes through flanged pipes b<3> to the accelerator chamber and, by a loosely fitting bored spindle d<1> having holes d, to a chamber b<1> above the diaphragms. The upper end of the bored spindle passes through a Muntz metal washer d<2> and enters a screwed-on thimble d<3>. When the air pressure falls, due to a sprinkler acting, the valve k, moved from its seating under the influence of the diaphragms, allows the air under pressure to escape from below the piston valve i so that it falls till its holes i<1> are in alignment with holes j<1> in the valve chamber. The air under pressure then escapes into the vessel b<2> and through pipes l<1>, l<2> actuates the differential valves and may also pass to an alarm. An atmospheric chamber h is located between the diaphragms f, g. The diaphragm g is larger than the diaphragm f to allow the air pressure to maintain the valve k against its seating in normal circumstances. An air-release valve m and a water-release valve n are fitted at the upper and lower parts of the accelerator casing respectively.
