[Also in Division H5] Dielectric welding apparatus, e.g. for producing P.V.C. vehicle seat covers, comprises brass bars 13 (to produce a fluted effect) resiliently mounted in a frame 17. The frame is hingedly mounted between conducting plates, to which the electricity is supplied, in the manner described in Specification 1,011,589. The bars 13 are bounded by a peripheral bar 12 castellated to produce an intermittent weld which may afterwards be sewn. The gaps allow the escape of air from'the work, which comprises a layer of P.V.C., a layer of plastic foam, and a base layer which may also be of P.V.C. or at least have areas coated with a weldable plastic. The bars are supported by insulated rods 22 passing through oversize holes, and they are separated by pairs of insulating strips 19 spaced apart by spacers 20 and plastic foam 21. The arrangement is such that a left and right pair of covers, sandwiched between the bars and the upper and lower conducting plates respectively, are produced at a time.

Title: Process for the manufacture of pantothenic acid and the salts thereof
IPC: C07C233/46
Filed: 1943-06-30
Abstract: Pantothenic acid is produced by the oxidation of d(+) - a g  - dihydroxy - b b  - dimethyl - butyric acid-(31-hydroxypropyl)-amide or the corresponding a g -diacetoxy compound, using as the oxidizing agent a permanganate such as potassium permanganate or barium permanganate at a temperature not substantially exceeding room temperature in dilute weakly acid solution.  In examples: d(+)-a g -dihydroxy-b b -dimethylbutyric acid-(31-hydroxypropyl)-amide is added to aqueous sulphuric acid and to the solution so formed a solution of barium permanganate is run in slowly, the temperature being maintained at 15-20 DEG  C.  The pantothenic acid is purified and crystallised in the form of its cinchonidine salt; (2) d(+) - a g - diacetoxy - b b  - dimethyl - butyric acid-(31-hydroxypropyl)-amide is dissolved in aqueous sulphuric acid and treated as in example (1). The d(+)-a  : g -dihydroxy-b b -dimethyl-butyric acid-(3-hydroxypropyl)-amide which is used as the starting material may be prepared by the process described in Specification 568,355, and the d(+)-a  : g -diacetoxy-b b -dimethyl - butyric acid - (31 - hydroxypropyl) - amide is obtained by the condensation of d(+)-diacetoxy-dimethyl-butyric acid chloride with g -hydroxy-propylamine in the presence of acetic acid ethyl ester.

Title: Improvements in and relating to the gripper mechanism of printing presses
IPC: B41F21/05
Filed: 1924-04-30
Abstract: 227,034. Bohn & Herber Maschinenfabrik und Eisengiesserei, and Finkhaus, O. April 30, 1924. Gripper mechanism.-To register sheets accurately in multi-colour and like printing-machines, the impression cylinders are fitted with gripper mechanism including lower sheet-supporting members which are capable of moving circumferentially and radially, and are projected so as to be held temporarily by fixed stops near the fixed sheet front stops while the grippers close on the registered sheets. In one form, Fig. 1, the movable grippers 3, which are opened by fixed stops acting on shoes 4, are moved clockwise to close the grippers, which are kept closed by springs 16. The grippers 3 press the sheets against a support 12 carried by spring-pressed rods 13 mounted to slide in rings 14 pivoted in the impression cylinder 1. The support 12 is normally pressed outwards by two springs 16 weaker than the springs 11, and the springs 18 pull the rods 13 in a counterclockwise direction so that stops 22 on the support 12 normally contacts with stops 23 on the cylinder 1. In the open position of the grippers 3, cams 21 on the shaft of the grippers 3 act on arms 17 of the support 12 and keep it from projecting from the cylinder. While the grippers 3 are closing on a sheet fed over a table 24 with a flexible extension 25 to a fixed front stop 27, the cams 21 permit the support 12 to be protruded from the cylinder. The support 12 moves into contact with the horizontal part of fixed guides 28, and moves along the horizontal part until it engages a vertical part of the guides 28. The support 12 is thus held stationary, while the grippers 3 close on the sheet by moving perpendicularly to the support. Finally the support 12 is depressed below the outer surface of the cylinder 1 and is freed from the. stop 28, thereby permitting the sheet to be advanced in correctly registered position. In a modification, Fig. 5, the support 12 is replaced by a support 29 carried by arms 30 pivoted about the gripper shaft 2. The coiled spring 18 is replaced by a bent spring 32 which is depressed by a cam 33 to act on a projection 31 on the support 29 when the grippers 3 are opened. The support 29 is normally pressed outwards by a spring- buffer 36 carried by an arm 35 on a shaft 34 manually held in operative position by an arm 41 held by a clamp 42 with an operating-handle 43. Blankets, fixing. The blanket 40 of the impression cylinder 1 is held in position by springs 39 on the shaft 34, the shaft 34 being moved in a counterclockwise direction to release the springs 39 when the blanket is being assembled.

Abstract: 1366854 Treating sewage J FROST 6 Aug 1971 [6 May 1970] 10788/70 Heading C1C A method of lowering the B.O.D. of sewage (or other effluent) comprises admitting the sewage in particulate form to a column, admitting hot oxygen or oxygen-containing gas to the bottom of the column with a velocity which suspends the particles in the form of liquid and optionally wet solids, and removing evaporated liquid and dry solids if present, from the top of the column. In the embodiment shown sewage is sprayed on to belt 10 associated with pressure roller 12. The bulk of liquid is collected in trough 16 and the bulk of the solids in hopper 14. Liquids with entrained solids is passed by pump and grinder 20 to column 26 where it is sprayed downwardly from jets 24. The sprayed particles are contacted by air heated in heat exchanger 32 and supplied by fan 28. The evaporated liquid and dried solids are carried by the air stream to cyclone separator 38, the solids being discharged through flap valve 48. The separated gas is passed through heated catalyst (e.g. Pt) chamber where any ammonia or methane is broken down, and heat exchanger 32 where it heats incoming air, to a condenser (not shown). The condensed liquid may have urea removed therefrom. The air may be at 130-150 F.

Abstract: 600,669. Dielectric heating. GENERAL ELECTRIC CO., Ltd., LEYTON, E. M., and NELSON, H. M. April 30, 1945, No. 10849. [Class 39(iii)] Pellets or preforms of moulding material are arranged in contact with, or adjacent to, an electrode having a co-operating electrode comprising independently movable elements each maintained in contact, or substantially in contact, with one of the pellets which are then heated by a highfrequency electric field induced between the electrodes. Thus a frame 1 is mounted on legs 2 and carries a rectangular plate 3 which supports a number of electrode elements 4 in register with apertures 10 in an insulating loading board 6 resting on a platform 5 which is slidably mounted vertically on the legs 2 by toggle levers 7, 8 with a control arm 9. The pellets are supported in the apertures 10 by a removable electrode plate 11. If the board 6 has recesses only it may itself form the lower electrode. Each electrode element 4 comprises a member 13 fixed to the plate 3 and a member 12 carrying a plate 41, the members being extended telescopically by a spring 14 to an extent limited by a rod 16. Thus after raising the platform 5, or alternatively lowering the frame 1, the electrode plates 4<1>, which are of smaller diameter than the apertures 10, are yieldably maintained in contact with the pellets. The electrode elements 4 may be grouped into spring-mounted units comprising, for example, two or three electrode elements tiltable about one or two suitable horizontal axes respectively. The electrodes are connected to a high-frequency electric source by leads 19, 20 the latter having connections 18 to the rods 16 if the plate 3 is non-conductive. The apparatus may be mounted in a chamber or oven having a door operating the arm 9. After heating, the board 6 may be located over a mould having cavities into which the pellets drop on withdrawing the supporting electrode 11.
