Title: Improved Mechanism for Treating Porous Vessels in order to render them suitable for Retaining Fluid or otherwise Preserving their Contents.
IPC: B28B11/04
Filed: 1917-12-29
Abstract: 123,125. Hadfield, G. H., and Bawtree, A. E. Dec. 29, 1917. Coating - machines. - Vessels such as cardboard boxes are coated with protective or other fluid by feeding them in succession to a revolving chuck, in which they are held while being coated automatically or by hand by brushing, spraying, &c. In the machine shown in Fibs. 1 and 2 of Provisional Specification 19228/17, the articles are stored in the column 1 and are fed by the reciprocating plunger 7 into the chuck 2, one article 6 ejecting the article 5 in front of it. The plunger 7 is attached to a swinging arm 8 to which motion is imparted by the cam 10 and spring 9. The chuck 2 is provided with spring jaws 3 for gripping the article and with a driving pulley 4. The shaft 12 on which the cam 10 is mounted may operate coating-mechanism or may carry means such as the arm 13 adapted to receive and deliver the treated articles. Fig. 2 of Provisional Specification 5685/18 shows a machine for coating the exterior of rectangular boxes. The plunger 7 which enters the box at the base of the column 1 is actuated by the cam 10 and spring 9. It is surrounded by a sleeve 7<A> having slots 7<B> which are engaged by the spring jaws 14 of the chuck 2, so that 'when the plunger is moved forward, motion is imparted to the sleeve 7<A> and to the box carried on the end of it. When the plunger 7 is withdrawn, the treated article is shipped from it by the edges of the jaws 14. The chuck 2 and camshaft 12 are driven by gearing. On the end of the shaft 12 may be mounted a compound cam 16 for operating spraying-apparatus. A modified apparatus, more particularly for coating the interior of large containers is shown in Fig. 1 of the Complete Specification. The containers 6 are fed from a hopper 1 containing a wheel 20, an arrangement of which avoids the weight of a column of articles pressing on the feeding- plunger. A worm on the chuck 2 drives the shaft 12 through the worm-wheel 22 and bevelgear 23, 24. The gear-wheel 24 is connected with the shaft 12 by a clutch, so that the feed can be interrupted without stopping the rotation of the chuck 2. A cam on the rear end of the shaft 12 may operate spraying-apparatus through a flexible connexion.

Title: New interpolyesters
IPC: C08G63/672
Filed: 1949-07-27
Abstract: Interpolyesters, capable of being drawn into fibres are made by reacting terephthalic acid or an ester-forming derivative thereof, a glycol of formula HO(CH2)nOH, where n is 2-10 and a high molecular weight polyalkylene oxide, each component providing recurrent linkages in the polyester chain and the polyalkylene content of the polyester not exceeding 20 per cent by weight. Specified derivatives of terephthalic acid are alkyl esters, cycloalkyl esters, aryl esters, acid halides, and ammonium or amine salts.  When using a dihalide of terephthalic acid reaction may be carried out in presence of an inert organic liquid and a base, e.g. pyridine, N - methylpiperidine, N-dimethylaniline or N-diethylaniline.  Reaction may be carried out in presence of an ester interchange catalyst, e.g. lithium, sodium or potassium or their carbonates or borates; calcium; beryllium; magnesium or its oxide; zinc; cadmium; aluminium; chromium; molybdenum; manganese; iron; cobalt; nickel; copper; silver; mercury; tin; lead or its oxides, e.g. litharge; bismuth; antimony; platinum or palladium. The alkali metals, alkaline earth metals and magnesium may be used in the form of their alcoholates formed by dissolving them in the glycol to be used or in methyl or ethyl alcohol.  In examples: (1) 100 parts dimethyl terephthalate, 96 parts ethylene glycol, and 16 parts polyethylene oxide of m.w. circa 1500 are reacted under nitrogen at 200 DEG  C. while distilling off excess ethylene glycol and methanol with reduction of pressure.  The melt obtained is extruded through a vent in the reaction vessel, dried, moulded into a rod and formed into filaments which are cold drawn at a draw ratio of 5.5-1.  These when treated with acetate rayon dyestuffs give excellent exhaustion of the dye liquor and depth of shade; (2) as in (1), the reaction being carried out in presence of 0.2 part of litharge; (3)-(5) as in (1), employing 10.4 and 21 parts respectively of a polyethylene oxide of m.w. 3000.

Filed: 1920-07-09
Abstract: 147,882. Siemens - Schuckertwerke. June 15, 1918, [Convention date]. Coils and conductors; windings.-For reducing eddy current losses and the " crowding " of current in the conductors of alternating-current machines, the conductors are divided into a number of components insulated from one another from the top to the bottom of the slot and connected between the slots by a single form of end connector such that the components are transposed outside the slots and each one occupies in the complete winding all of the possible positions in the slot. The winding is subdivided into branches connected in parallel, the number of which is equal to or a multiple of the number of subdivided conductors arranged one above the other, and each branch contains a number of conductors equal to the number of slots. Fig. 1 shows a six-part conductor in successive slots, the components being marked 1 - - 6 and the cyclic displacement of No. 1 being shown by the crosshatched areas. The end connectors for both front and back ends are all of the form shown at 1<1> - - 6<1> in the perspective diagram of 3 slots in Fig. 1<a>. In this case, the displacement pitch is unity, but any other pitch may be used. Fig. 5 shows the transposition in the components of a twelve-part conductor in two vertical groups, the end connectors being as shown in end elevation in Fig. 6 to give a cyclic displacement of two steps. When the number of components placed above one another is odd the displacement pitch is made one greater than this number. Thus, as shown in Fig. 5, with the total number n of components in the slot equal to 10 and two vertical groups being employed, the displacement pitch is n/2 + 1 = 5, as shown by the cross-hatched areas. The components are lightly insulated from one another by a thin lacquering or enamelling.
