Filed: 1946-07-11
Abstract: 621,966. Collectors. ANGUS, A. B., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. July 11, 1946, No. 20769. [Class 104 (iii)] A collecting bow, resiliently supported on the carrier head of a pantograph frame, is maintained in its position transverse to the direction of travel but isallowed a small movement in and perpendicular to the direction of travel. As shown in the perspective view, Fig. 1, and part perspective view, Fig. 2, a collecting bow O is supported at each end by a spring M acting on a block N pivotally mounted in the bow with the spring supported on an abutment provided by the hub portion H of a rocker G fixed on a rod F which is pivoted in and extends between two platforms in the form of rectangular frames A carried by the upper arms D, D<SP>1</SP> of the pantograph. A slotted link P pivoting on the pivot pin of the block N slides by its slot over the rod F, the slotted link P normally being centralized by abutment rollers J on the rocker G, the latter having a lug K centralized by springs L on the platform. If the bow collector meets an obstruction it can move backwards against the action of the centralizing springs L or can move vertically against the action of the spring M. The rod F ensures that the rockers, at each end move equally so that the two ends of the bow collector are moved backwards equally. A second rod T in a corresponding manner ensures that both ends of the bow move downwards equally by reason of the rod T having lever arms S, Fig. 3, at each end which are linked to the bow collector at Q. The rectangular-frame platforms A are carried on the pantograph arms D, D<SP>1</SP> by blocks with pivot pin connections to the frames, one pivot pin moving in a lengthened slot C in the platform frame, Fig. 5. The other pivot pin is provided by the rod T being extended. The rods F, T also maintain the platforms in a common plane.

Title: Improvements in or relating to machinery guards
IPC: B31B3/72
Filed: 1922-07-29
Abstract: 204,453. Etheridge, J. R. July 29. 1922. Guards, controlling; stopping machinery by movement of guards.-In guard's for power presses, especially corner-staying machines for cardboard boxes, of the type in which pivoted arms sweep over the anvil as the plunger descends and are connected with mechanism acting to declutch the driving-means if they are obstructed, the arms first execute a downward movement and are caused to open out only when in close proximity to the anvil. Guards 1 are carried by rods 3 mounted on either side of the plunger 2 of a cornerstaying machine. The rods 3 are guided in bearing-sleeves 4 pivoted on the plunger 2 and normally held vertical by a spring 28 pressing apart arms 25. The rods are linked to slotted levers 7, which are pivoted on fixed pins 8 carrying rollers 29 and are connected each by a link 9 to an arm 10 on a rock-shaft 11. The shaft 11 carries a further arm 14, Figs. 1 and 4, having an adjustable pivoted portion 14a in contact with a cam 15 on the main shaft 16. The arm 14 is provided with a hollow screw 14d, Fig. 4a, and the portion 14a with a screwed stem 14c and a nut 14e. When the rock-shaft is released by the cam 15, the guard's 1 descend under the action of gravity and a spring 31. When the plunger 2 descends, rollers 26 carried by the arms 25 are moved inwards by fixed cams 27, so tilting the sleeves. 4 and spreading the guards 1 over the anvil 28 to give passage to the die 33 and to remove the operator's hands. Should either movement of the guards 1 be obstructed, the arm 10 does not make a full movement, and a trip-block 22, Figs. 1 and 4, connected thereto by adjustable linkage 17 - - 21, is insufficiently withdrawn from the path of a declutching-trigger 23, so that the machine is stopped. When so stopped, it can be restarted only by pulling a rod 40 connected to the bolt 21, in order forcibly to disengage the wedge-shaped face of the trigger 23 from a notch in the block 22. The gummed strip, fed through a slot 42 and cut during descent of the plunger, is received on fingers 32 slidable on members 34, which are pressed by springs 35 against adjustable stops 36, Fig. 1. The plunger, in descending, engages its corners 2a with the members 34, thereby carrying the fingers 32 into contact with the anvil, which slightly opens them against springs 39 to release the gummed strip. According to the Provisional Specification, the bearing- sleeves 4 are slotted to engage a pin on the lower part of a slide carried in the plunger and operated to tilt the sleeves by a bell-crank, which is mounted on the top of the plunger and has engagement with a fixed cam slot.

Title: Preparation of solid and semi-solid polymers of olefinic hydrocarbons
IPC: C08F10/00
Filed: 1943-12-17
Abstract: <FORM:0579894/IV/1> Solid and semi-solid polymers and interpolymers of olefinic hydrocarbons are made by polymerizing at elevated temperature and pressure, separating the gaseous and non-gaseous constituents of the reaction mixture at two or more pressures and recycling the gases at these pressures with recompression to the polymerization pressure if necessary.  Catalysts, e.g. oxygen; hydrogen, diethyl, lauroyl, tetralin, urea, butyryl and benzoyl peroxides; persuccinic acid; alkali and alkaline earth metal and ammonium persulphates, perborates and percarbonates may be present. Olefines specified are ethylene, propylene and isobutylene, which may be interpolymerized with styrene; vinyl acetate, formate and isobutyrate; vinyl chloride; vinyl ethers; divinyl formal and butyral; methyl vinyl ketone; acrylic, methacrylic, itaconic, crotonic and fumaric acids and their esters, acid halides, amides and anhydrides.  Ethylene from a gas holder 1 is compressed by a compressor 2 to 150 to 500 atmospheres and passed into a cooler 3 or 3a.  Benzene may be introduced into the ethylene stream from a storage vessel 5 by an injector 6.  The gas is further compressed to 800 to 4000 atmospheres by an injector 7 and introduced into a converter 8.  Water from a storage tank 4 is mixed with the catalyst in a vessel 4a and also introduced into converter 8 by an injector 9. The converter temperature is controlled to a value between 40 DEG and 400 DEG  C.  The pressure of the mixture is reduced by a reducing valve 10 to between 150 and 500 atmospheres, the gases, separated in a separator 11 from the liquids and solids, returning after cooling to the initial compressed, ethylene stream.  The liquids and solids pass through an extrusion valve 12 into a second separator 13, which is kept below 150 atmospheres and preferably at atmospheric pressure, from which the product is extruded through an extrusion valve and the gases are returned to the initial ethylene stream, preferably after cooling in a cooler 14.  The two coolers 3 and 3a are employed alternately for cooling the ethylene, which is recycled at a pressure between 150 and 500 atmospheres, so that the process may operate continuously. Specifications 471,590 and 497,643 are referred to.
