Filed: 1929-06-05
Abstract: 333,672. Lees & Co., Ltd., H., and Biles, A. W. June 5, 1929. Recording particular operations.-In apparatus for recording the delivery of materials from bulk (e.g. coal into railway locomotives) the successive movements of a manually inserted key close the switch 19 of an electric motor (which drives the delivery apparatus and the recorder), clutch the recorder to a shaft 2 driven by the motor and print an identifying number 25 from the key. The shaft 2, driven from the motor, carries a friction clutch 7 adapted to engage a drum 3. which is loose on shaft 2 and carries peripheral type denoting quantities as well as a disc 4 having indications shown at a window 5. The drum is normally rotated counter-clockwise, Fig. 1, to zero by a weight 6. Under this drum are a record band 10 and carbon band 12 rotated step-by-step by lever 13 and a pin 14 on disc 4. Below drum 3 is a plunger 15 in line with a switch 19 maintained open by a spring. Plunger 15 and a member 16 are connected by parallel-motion links 17, 18 pivoted at 27 to the fixed framework and nesting into slots in a bar 20, which tends to swing from right to left, Fig. 1, on arms 21, 22. When the key is inserted its end 24 moves the lower end of arm 8, Fig. 2, against the action of a spring 9, so that clutch 7 moves against drum 3. On turning the key a lug 25 thereon depresses member 16 and prints the identifying number 12345; member 16 carries with it plunger 15 so that switch 19 is closed and the electric motor operates the delivery apparatus and the shaft 2, rotating drum 3 against the action of weight 6. At the same time, links 17 leave their slots and bar, 20 moves to the left so that its uncut upper surface locks links 17 and members 16, 15. This locks clutch 7 in the engaged position and locks the switch 19 closed. At the end of the operation the key is returned and withdrawn, the spring of switch 19 flinging plunger 15 up sharply to print off the drum 3 on to the strip 10. At the same time a lug 26 on the key moves an extension 23.of arm 22 so as to restore bar 20 and links 17.

Abstract: 145,587. Marsollier, C. J. Feb. 8, 1916, [Convention date]. Two-part couplings; needle-point couplings; binding-posts; wire couplings.-A connecting device and lamp.holder comprises plungers 6, Fig. 1, in tubes 16 in an insulating block and connected to the conductors 2 by pins 18 passing through the tube and the insulation of the conductor or by countersunk screws 19. The pins or screws secure the plungers 6 within the block. The conductors are passed from opposite sides through an opening in the block to take any strains. According to the Specification as open to inspection under Sect. 91 (3) (a), means for connecting cables, wires, and other conductors are characterized by the contacting surfaces being situated out of the direct line of pull of the connected conductors. As shown in Fig. 1 (Cancelled), a lead 2 is passed through an insulating body 1 and bent back into a depression 3 wherein its bared end is placed in contact with a member 5 carried by a second insulating body 4. This contact may be maintained of itself or by means of accessory parts. Contact members mentioned are points, screws, pins and plungers. The backward bend of the conductor is stated to diminish any pull that may be exerted upon the conductor or conductors. Fig. 2 (Cancelled) shows the application to a lamp-holder wherein one or more conductors 2 are fitted to an insulating body 1 and one or more conductors 6 are fitted to a second insulating body 4 and the two are held together by a mechanical connecting device, comprising a casing 7 and the cap of a lamp, which takes all strains tending to pull the connected conductors apart. Contact is in this case made by pins 5 which enter the turned-back ends of conductors through their insulating coverings. In a modification bared conductors are bent back into recesses, where they are secured by screws, with the heads of which plungers on a co-operating part of the coupling engage. The strain of the conductors may be taken by passing them wholly or partly round insulating members such as 21, Fig. 7, (Cancelled), or by means of knots, loops, or wavy bends therein.

Title: Method of producing polymers of aromatic vinyl compounds
IPC: C08F2/00
Filed: 1951-07-27
Abstract: <PICT:0711611/IV (a)/1> Copolymers of aromatic vinyl compounds and esters of polyvalent alcohols containing unsaturated fatty acid radicals are obtained by continuously introducing the vinyl compound under atmospheric pressure at one or more points into a circulatory system of the ester preheated to a temperature above the boiling point of the vinyl compound, at a rate such that the reaction is completed before the aromatic vinyl compound can evaporate.  Aromatic vinyl compounds mentioned are styrene, a -methyl styrene, nuclear halogenated styrenes and vinyl naphthalene, and the esters may be oils such as olive, groundnut, palm, rape, cottonseed, poppy-seed, soya, sardine, fish-liver, menhaden, pilchard, linseed, perilla, wood and oiticica oils.  In addition, alkyd type esters with for example, phthalic, adipic and maleic acids with alcohols such as glycerol glycol, pentaerythritol, trimethylol-ethane and propane, mannitol, sorbitol and hexane triol.  The esters may be modified to form stand or blown oils.  Solvents such as carbon tetrachloride, benzine, turpentine, benzene, chlorobenzene, toluene, xylene, and ethyl benzene may be used together with a catalyst such as benzoyl peroxide.  In the apparatus shown the heated ester circulates under nitrogen, supplied by pipe S, between vessels A, B and styrene is injected continuously into pipe D by a pump F, e.g. over a period of 24 hours, after which heating is continued, e.g. for 6 hours to thicken the product.
