Title: Improvements in and relating to self locking stay mechanisms
Inventor: BIRMINGHAM DOUGLAS WILLIAM
IPC: E05C17/32
Filed: 1962-01-17
Abstract: 1,000,997. Hinges; stays. F. T. PRODUCTS Ltd. Jan. 9, 1963 [Jan. 17, 1962], No. 1772/62. Heading E2F. A locking hinge or stay comprises a pair of members 11, 12 (Fig. 1, 6) pivotally connected by a pivot pin 13 and provied with overlying surfaces 14, 15 formed with slots 16, 17, and a double-ended pawl 18 having its thickness accommodated partly in one slot and partly in the other, the pawl being displaceable within the slots but being yieldingly constrained to maintain its instantaneous orientation relative to the members, and the slots being so shaped that when the members are opened to the fullest extent permitted by the pawl and then slightly closed the pawl locks them in the position shown in Fig. 6, and when they are again opened fully the pawl is released so that they can be fully closed. During each opening and closing cycle, which is described in detail in the Specification, the pawl rotates through 180 degrees. The pivot pin 13 fits tightly in an aperture 15a in the member 12 and passes freely through an aperture 14a in the member 11, and at each end it is provided with an annular groove so that it engages tightly in bores 21, 22 in a pair of caps 19, 20 made from resilient material. The caps bear frictionally against the opposite sides of the pawl to provide the yieldable constraint; in a modification they comprise spring steel discs with separate synthetic plastic covers. The invention may be applied to a telescopic locking stay (Figs. 13, 15) comprising a member 72 slidable in a C-section member 71. The pawl 75 is located in a slot 73 in the member 71 and a recess 74 in the member 72, the yieldable constraint being provided by a spring cover plate 76 sprung over the member 71. Fig. 13 shows the stay in the position corresponding to Fig. 6, the members having been fully extended and then slightly retracted to be locked by the pawl. The yieldable constraint may be provided by magnetic attraction between the pawl and a suitable surface.

Title: Low temperature polymerization
IPC: C08F110/00
Filed: 1950-01-24
Abstract: In the low-temperature polymerization of mono-olefins, e.g isobutylene and iso-octene, alone or with multi-olefins, e.g. butadiene, isoprene, dimethyl butadiene, myrcene, dimethallyl, 2-methyl-3-nonyl- and 2-methyl-4-pentyl-butadienes and cyclopentadiene, dissolved in a non-reactive solvent which also dissolves the polymer, e.g. propane, butanes, pentanes, hexanes, light naphtha and carbon disulphide, the feed is led to a circulating polymerization system to which a Friedel-Crafts catalyst is added and wherein conversion is controlled so that the polymer solution is still flowable, and a polymer containing stream taken from the system is passed in counter-current <PICT:0682695/IV (a)/1> heat exchange to the feed to cool the latter and warm the polymer solution to reduce both its viscosity and precipitation of polymer.  Monomer-solvent feed from pipe 1 passes through heat-exchangers 2, 3, 4, 5, 6 and calcium chloride drier 7 to a polymerization system 9 comprising coolers 11, 12 alternately connected by pipes 14, 15 through a circulating pipe 16 and catalyst injecting nozzle 17 to polymerizing drum 19 and pump 21. A pump 25 withdraws dilute polymer solution to storage drum 26, whence it passes through the heat-exchangers in reverse flow to the feed, and by pipe 27 through a preheater 28 to drums 29, 38 and associated boilers 36, 41 where most of the solvent and unreacted monomer is vaporized and recovered in still 33. Concentrated polymer solution (15 to 25 per cent of polymer) from drum 38 is delivered by pipe 43, together with steam from pipe 47 and water from pipe 40, to a flash drum 44 provided with a stirrer, where all the volatiles are removed, leaving a slurry of polymer in water which is further purified in drum 73 and withdrawn by pipe 75 to the usual drying and purifying plant. Vapour discharged from the top of drum 44 is condensed at 48, water separating through pipe 51 and liquid hydrocarbons through pipe 52 to fractionating towers from which monomers and solvent are recycled.  A slightly modified apparatus for use with higher boiling solvents is also described.ALSO:<PICT:0682695/III/1> Volatile material is removed from a polymer solution (see Group IV(a)) by passing the solution through pipe 43 to flash tank 44 together with a steam jet from line 47 and a water jet from pipe 40 whereby the solution is broken up into droplets.

Stream-cutting machines; extrusion machines. -Relates to machines in which meal for cattle food is compressed und forced through openings in a die plate, the extruded portions being cut off to length by a knife which is stationary when the die rotates, and is rotated when the die is fixed. According to the invention, the ends of the die openings remote from the compression means are closed during a part of the compressing action, being opened again a certain time or distance interval before the operation of the knife so as to cut off pieces of uniform length and to regulate the degree of compression. In a machine in which the meal is extruded through openings a', Fig. 1, in a fixed die plate A by a rotating worm, a closure plate D having a sector d cut away is mounted on the end of the worm shaft to rotate with the worm or to be driven at any desired speed by suitable gearing. The knife E is secured by screws e<2> to an inclined facing on the plate D and forms one edge of the gap d, the other edge d<1> being formed by a piece D' secured to the closure plate by screws d<2>. The angle of the gap may be varied by using making up pieces D' of different sizes, thereby regulating the length of material cut off, and its degree of compression. In a machine of the kind described in Specification 237,944, in which meal is extruded from the interior of a rotating ring G through openings g<1> by an eccentrically mounted compression roller H, the closure plate D<2> is a section of a cylinder and is secured to a fixed part of the machine by bolts d<6> passing through elongated slots d' to permit angular adjustment between its edge d<8> and the line of contact h between the ring G and roller H. A fixed knife cuts off the extruded portions. An extension D<3> of the plate D<2> may be provided, this extension being spaced apart from the ring G a distance equal to the desired length of the moulded pieces. In a modification the extension may be so shaped that its distance from the ring G starting from the edge d<8> gradually increases.
