Title: Improvements in or relating to portioning machines
IPC: G01G13/00
Filed: 1962-05-02
Abstract: 966,414. Separating and sorting by weight. ARENCO A. B. May 2, 1962 [May 19, 1961], No. 16924/62. Heading G1W. [Also in Division B8] A portioning machine which portions, by weight, granular materials into receptacles 8 (Fig. 1) moved one at a time by conveyer 2 to a weigh pan 10 beneath a shutter controlled discharge opening of a coarse portioning container 22, of which the shutter 24 when closed forms the bottom. The container has a volume equal to or less than that of a required weight of material. If underweight is indicated a further small amount (fine portioning) is discharged from a table 23 through the open container 22. When the proper weight is in a receptacle 8 the two upper contacts of a switch S3 (Fig. 2), attached to the weigh pan, engage so actuating relays K11, K12, K1 to energize electromagnet Y1 causing a hook 27 to disengage an arm 26 and the spring 28 thereby rotates a rod 25 to close the shutter 24. Actuation of relay K12 also energizes relays K13, K14 and then contactors K4, K5 causing motor 21 to start and turn shafts 14, 32 to a predetermined angular position in which a cam disc 53 closes switch S6 and connects the negative pole to relays K31 to K35 and K24, K25. If overweight the three contacts of S3 mutually engage providing a positive feed to relay chain K31 to K35. These relays are associated with reject mechanism comprising an electromagnet. Y3 which is energized when relay K35 is actuated and moves a locking bar 51 so as to prevent movement of an ejector arm 47 which serves to divert only correct weight cans along a path 46. If underweight the position of switch S3 is as shown Fig. 2 and K31 to K35 are also energized and the same procedure follows. Relay K24, in cooperation with switch S4 operated by a can on the conveyer is energized if a can is missing one step before the weigher. K25 then operates closing contactor K2 to energize electromagnet Y2 which prevents opening of the shutter 24. The switch S4 may be a photo-cell. The opening device for the shutter is synchronized with a device to lock the scale pan when filling a can.

Patent GB-1110412-A (GB)
Title: Improvements in or relating to chromium plating
IPC: C09G1/08
Filed: 1965-04-22
Abstract: A decorative chromium plate is formed on a metal by first forming on the surface a thin coating of a hydrogen-acceptor composition, i.e. compositions which react with hydrogen and which raise the hydrogen overvoltage at the metal as cathode, and then electro-plating chromium on to the metal thus coated in such a manner that substantially none of the coating remains in the final product. Typical hydrogen acceptor compositions are natural and synthetic rubbers; styrene, acrylate, acrylonitrile and butadiene monomers and polymers; acetylenic compounds; ethylenically unsaturated non-aromatic compounds; non-aromatic compounds with groupings -N=N- and >C=O sulphur; carbon disulphide; organic sulphur-containing compounds; antimony oxide; arsenic oxide; arsenous acid; 2-nitrobenzene arsonic acid; p-(phenylselenyl) aniline; hippuric acid; ethylene dicyclohexanol; and perthiocyanic acid.  The organic compounds may form continous films of 10 to 2000A thickness while the sulphur coating may be discontinuous. The coatings may be formed by dipping, spraying, swabbing electro-phoretic deposition or electrolytic action and may be dried before the electroplating step. The organic composition coatings may also include protective colloids such as gelatine, gums, cellulose ethers alginates and pectins and may be subjected to cathodic treatment, e.g. in dilute sulphuric acid before chromium plating which typically is effected from a chromic acid bath containing sulphate and silicofluoride at 42 to 43 DEG C. to give a micro-cracked deposit at a thickness greater than 0.25 micron.

Abstract: 380,483. Coated sheet material. DU PONT CELLOPHANE CO., Inc., 2, Park Avenue, New York, U.S.A.-(Assignees of Charch, W. H.; Elliott Apartments, Linwood Street, Buffalo, New York, U.S.A.) June 16, 1931, No. 17462. Convention date, June 17, 1930. [Class 140.] Transparent sheet material such as sheets or films of regenerated cellulose or cellulose derivative, or sheets or films of albuminous material are coated with a composition free from cellulose derivatives and comprising a resin and a wax or a wax-like substance in such proportions as to render the coating moisture proof and to provide a non-tacky, non-greasy, and transparent material. The composition may also contain a plasticizer. The resin may be a natural or synthetic resin or mixture of resins ; resins prepared from vinyl derivatives, modified polyhydric alcoholpolybasic acid resins, and resins produced from chlorinated diphenyl may be used. The wax is preferably paraffin wax, but Japan wax, spermaceti, ceresin wax, beeswax, petroleum jelly, and stearin may be used. The plasticizer may be tricresyl phosphate, castor oil, dibutyl phthalate or other known material. In general, the weight of resin exceeds the weight of wax or plasticizer alone ; the proportion of wax necessary to produce a coating of the desired properties is not large ; generally a weight of less than one-third that of the resin is sufficient. Solvents may be used to produce the composition, or the ingredients may be melted together. The composition may be applied to the sheet material in any manner, and the coated material is dried, preferably at a temperature equal to or above the melting point of the wax. After drying, the material is preferably humidified. In examples: (1) 15 parts by weight of a polymerized product made from vinyl chloride and vinyl acetate, 3 parts of paraffin wax, and 7 parts of tricresy1 phosphate are dissolved in toluene, and sheets of regenerated cellulose immersed therein. (2) A composition comprising a resin prepared from glycerin, phthalic anhydride, rosin and chinawood oil acid, paraffin wax, and castor oil is prepared and used as in the previous example.

Title: Improvements in or relating to electric protective relays
IPC: H02H1/04
Filed: 1934-06-13
Abstract: 437,902. Electromagnetic relays. NALDER BROS. & THOMPSON, Ltd., 97, Dalston Lane, and LIPMAN, C. L., 9, Stamford Grove East, Stamford Hill, both in London. June 13, 1934, No. 17492. [Class 38 (v)] A protective relay comprises a device which, when energized by A.C. and/or transient, intermittent or pulsating current tends to move the operating member of the relay in a direction in which a second device upon energization by direct current tends to move it, both devices being connected so as to be energized from the same source of supply. The relay may further be provided with a time-delay device. As shown in Fig. 1, the movable members of the two devices are mounted on a common shaft the upper member comprising an induction disc or vane B<2> movable between the shaded poles C<1> of an electromagnet C and the lower one comprising a moving coil B moving in the air gap of an electromagnet A or a permanent magnet. The shaft carries also a contact E co-operating with a fixed contact E<1>, operation of this contact being prevented by the restraining action of A.C. or intermittent current on the disc and closure of the contact being produced by a sustained direct current. The complete operation of the relay may, however, be controlled by a time-delay device which may be separate from the relay or mounted on the same shaft. As shown in Fig. 3, the time-lag device comprises a spring-driven eddy-current braking disc B<3> moving between the poles of a permanent magnet, the device being normally held out of operation by the core J of the electromagnet K which is acted upon by a spring L which normally overcomes the adjustable driving spring D<4>. The permanent braking magnet may, alternatively act directly on the disc B<2>. In this arrangement A.C. components are diverted from the moving coil device by a choke M, and the moving- coil section may be replaced by a dynamometer-type device. The time-lag device may in other modifications consist of a tilting- mercury tube electromagnetically-operated, Figs. 5 and 6, (not shown). Setting of the relay and time-lag device may be such that operation of the relay to complete a tripping circuit may be produced by D.C. sustained for 0À2 second. The relay may however be arranged to operate on A.C. with a D.C. restraint.
