Abstract: 372,163. Umbrellas &c. KRœGER, P. K. H., 5, Lutticherstrasse, Berlin. July 13, 1931, No. 20126. Convention date, July 18, 1930. [Class 134.] In umbrellas wherein the ribs 6 are not hinged to the stick 1 or to a central member, there is provided on the stick an abutment 8 over which the cover 3 may be drawn by a tensioning device so that the ribs are drawn towards the centre and the cover is held taut. The upper end of the stick is reduced in diameter as at 1<1>, and carries flanges 21, 22 between which the cover may be clamped. The abutment is secured on the reduced end by a sleeve 9. The tensioning device may comprise a plate or cup 10 movable on the stick and have a sleeve 10<1> formed with a bayonet slot adapted to engage a pin on the stick. The cup may thus be moved up to draw the cover round and over the abutment so as to give it a rigid cone shape. The cover may be made of waterproof paper having on one or both sides central reinforcing shields 4, 5, which with the cover are connected to the ribs by wire staples 7. The ribs and cover may be connected by a cementing medium and the rim reinforced by folding the cover over.

Abstract: Chlorotrifluoroethylene and a vinyl ester of an organic acid are copolymerized by heating in the presence of a per-compound. The vinyl ester may be vinyl acetate, propionate, butyrate, benzoate or stearate.  Per-compounds specified are benzoyl and lauroyl peroxides; hydrogen and diethyl peroxides; tert-butyl hydroperoxide; ammonium, sodium and potassium persulphates. There may be included ethylene, propylene, isobutylene, styrene, butadiene, chloroprene, fluoroprene, isoprene, vinyl and vinylidene chlorides and fluorides; acrylic and methacrylic acids, their esters, e.g. methyl acrylate and methacrylate, anhydrides, amides and nitriles; tri- and tetra-fluoro-ethylenes. Polymerization may be effected in bulk, in solution in benzene, methanol, cyclohexane, or tert-butyl alcohol, aqueous dispersion or emulsion and at elevated temperature and pressure.  The copolymers may be made into films and fibres.  They may be hydrolysed by adding a solution of potassium hydroxide in butanol to a solution of the copolymer in toluene and refluxing.  The copolymer may be compounded with carbon black, stearic acid, zinc oxide, sulphur and tetraethylthiuramdisulphide and vulcanized by heat.  The copolymers may be combined with or prepared in the presence of plasticisers, stabilizers, fillers, pigments, dyes, softeners and natural or synthetic resins.

Title: Process and apparatus for the ensilage of green fodder
IPC: A23N17/00
Filed: 1931-07-16
Abstract: 386,673. Storing and preserving crops ; cutting and slicing vegetables; food for animals. HOPPE, H., 14, Luneburgerstrasse, Magdeburg, Germany. July 16, 1931, No. 20380. [Classes 5 (i) and 5 (ii).] A process for the ensilage of green fodder consists in coarsely chopping the fodder to a fragmentary pulp, removing air therefrom and feeding the said pulp in a substantially air-free state to a silo, where it is caused to undergo lactic fermentation in absence of air. Fodder is fed to a chopping machine 1 comprising radial knives 2 provided at their free ends with scoops 6 whereby it is ejected into one of the pipes 7, 36 according to the adjustment of a slide valve 62, and so passes either by way of a compensating container 8, including a conveying worm, or directly, to a second comminuting machine 3. The latter comprises a fixed grinding crown 11 and a toothed grinding disc 13 provided on its periphery with shovels 14 which throw the fodder into a vertical mixing tube 15 whence it passes through a pump 19 to a silo 20. Substances such as sugar, salts, acids, starch, bran, or potato parings are dissolved or macerated in water in a container 21, water being introduced from the container 23, and pass therefrom through a pipe 27 into the comminuting machine 3. Further liquid which may contain lactic acid cultures, may be introduced into the pipe 27 or mixing tube 15 from the container 22. The supplemental materials may, if desired, be fed into the machine 1 or to the machines 1 and 3 simultaneously ; the mixing vessel 15 may then be omitted. A valve 58 in the pipe 27 is automatically controlled by the rising and falling of one of the drawing-in rollers of the machine 1, through links 33, 34. The comminuting machines and mixing tube serve to eliminate air, the residuum of which may be driven out by steam or partial vacuum during or after the filling operation : the air in the silo may, before the introduction of the pulp, be replaced by carbon dioxide, nitrogen, or other inert gas.

Abstract: 1426703 Applying metal foil blanks to bottles JAGENBERG-WERKE AG 9 May 1974 [15 May 1973] 20460/74 Heading B8F A method of applying metal foil blanks 5 to bottles or like containers comprises automatically applying gum to a blank removal member 3, bringing the gummed removal member into contact with a stack 6 of blanks and removing a single blank from the stack, folding over the leading edge of the blank during transport to a gripper cylinder 8, engaging the folded edge by a gripper 7, and transferring the blank to a moving container. The edge of the blank to be folded overlaps the leading edge of the gummed removal member to avoid application of gum to the blank edge. The folding operation is performed through 180 degrees by folding members 11, 12 in two steps. A blank is stuck laterally to the neck of a bottle 10 moving on a conveyer 9 when released by the gripper 7, and the bottle is then rotated so that the blank is folded around the neck, pressed down and then smoothed.

Filed: 1966-05-10
Abstract: 1,144,485. Sets. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 3 May, 1967 [10 May, 1966], No. 20673/66. Heading H4J. [Also in Division H1] A subscriber's instrument has a gravity switch mechanism provided with means for magnetically assisting its operation. A permanent magnet 2 (Fig. 2A) is mounted on the longer arm of a 14 : 1 ratio lever 4 adjacent the end on which an operating plunger (not shown) acts in the direction F. As the plunger is depressed and the lever 4, pivoted at 10, approaches a mild steel plate 6 the magnet 2 is attracted to the plate 6 with increasing force. The other arm of the lever 4 is coupled to the operating comb of a springset 12 and has a return spring 14. A residual gap 8 remains when the plunger is fully depressed and limits the attractive force to a value which can be overcome by spring 14 when the plunger is released. The strength and/or positioning of the magnet 2 on the lever may be adjusted. Alternatively the magnet 2<SP>1</SP> (Fig. 2B) is fixed and attracts the longer arm of a mild steel lever 4<SP>1</SP>. A non-magnetic stud 16 provides a residual gap 8<SP>1</SP>. In another example, a mild steel lever 4<SP>1</SP> (Fig. 2C) co-operates with a horseshoe arrangement of a bar magnet 18 and an L- shaped soft iron polepiece 20. A stud 16 provides a residual gap. The mechanism permits use of a lightweight handset having the hand grip extending from front to back across the instrument body and over the telephone dial.

[Also in Division F2] Particulate material, e.g. chaff, is supplied to troughs at individual milking stations through pairs of valves 17, each valve being formed by a waisted tubular-rubber moulding 18 in a tubular-steel jacket; the jackets of each valve of a pair are bolted together as well as to a supply hopper 15 and a discharge duct 14. The annular spaces between each jacket 20 and valve 18 are connected by control means to a vacuum pump whereby the spaces may be exhausted so distending the tubes 18 to enable material to flow therethrough. The upper and lower valves of a pair are operated in succession, which may be cyclical, and each operation delivers a measured quantity of material. The measured quantity may be varied by inserting a length of tubing between each pair of valves. The tubes 18 may be positively closed by applying pressure to the annular spaces 19 and the valves may control the flow of granular material or liquids.
