Patent DK-10498-A (DK)
Inventor: KONGSGAARD BJARNE
IPC: A01K1/015
Filed: 1998-01-26
Abstract: There is described a method and a layout for strewing in a farm animal barn and a dispensing unit for application thereof. In the invention, litter is produced in granular form or friable form and fed from a storage to the farm animal barn via transport elements 1, which deliver the litter in dispensing units 2 with an essentially horizontal pipe 9. The outlet end 10 of the pipes is arranged indirectly above the floor surface. The litter is dispensed in that the animals act on the lower end of the pipe, bringing about a swinging of the pipe, which produces a dispensing of litter onto the floor surface 11. The litter is then distributed by the animals. The dispensing unit, which comprises the dispensing pipe 9, is mounted in a fitting 17, which is elastically yielding, and which comprises at least one undulating piece 19, designed to bring the dispensing pipe 9 back into a position of rest after the activity of the animals ceases. Such a dispensing pipe can be used for strewing, for feeding, and/or a combination of strewing and feeding. <IMAGE>

Abstract: 570,769. Centrifugal pumps. STEVENS, A. H. (Thompson Products, Inc.). Jan. 7, 1944 No. 339. [Class 110 (i)] A gravity-fed centrifugal pump, particularly for an aircraft fuel system, is provided with a baffle at the inlet for breaking up the vortical flow of fluid as it enters the pump so that the fluid enters axially and any vapour separated from the liquid by the agitation of the impeller is enabled to escape readily up the outside of the axial column of fluid without being trapped in the descending fluid to accumulate in the throat and prevent entrance of the fluid to the pump. In the embodiment illustrated, the impeller 25 has curved vanes 27 with tapered inner ends, and works in a casing 17 with an inlet throat piece 20 preferably having a flared surface 37. A baffle plate 38 (shown in longitudinal section) extends diametrically across the throat to break up any rotational motion of the fluid entering the pump. The baffle 38 may be in the form of a cross instead of a single diametical plate, and may be integral with, or welded or otherwise fixed to, the throat piece 20.

Abstract: 380,683. Change speed gearing ; clutches. HUNKEMÍLLER, L., 50, Romanshornerstrasse, Arbon, Switzerland. Jan. 11, 1932, No. 765. Convention date, Jan. 13, 1931. [Class 80 (ii).] Change-speed gearing for motorvehicles comprises a claw clutch sleeve 9 and a friction clutch sleeve 19 which are normally rigidly connected together and jointly displaced for the application of the synchronizing friction clutch, and hand-operated means for separating the two sleeves to allow the claw clutch sleeve to be moved independently into engagement. A pinion 2 on a driving-shaft 1 and a countershaftdriven wheel 6 loose on a driven shaft 7 are each provided with clutch claws 40 and with a friction cone 41. The claw sleeve 9 with two rings of clutch claws 42 is splined on the shaft 7, and loose upon it is the sleeve 19 with two female friction cones 43 corresponding. The inner sleeve 9 is connected by bolts 10, passing through slots in the outer sleeve 19, to a striker ring 12 engaged by a selector-fork 13 on a guide-rod 21. A second fork 20 slidable on the same rod 21 engages a strikergroove in the outer sleeve 19. The forks are normally coupled by a spring latch-lever 22 so as to be slidable together by a control lever 14 so as to bring one pair of friction cones 43, 41 into engagement to effect synchronism of the adjacent clutch claws. The latch lever 22 is then disconnected from the fork 20 by depressing a rod 25 which passes down through the control lever and engages the tripping end of the latch lever. Continued movement of the control lever 14 then brings the synchronized claw rings 42, 40 into engagement to effect positive driving. In a modification, the latch lever is replaced by a spring plunger which is raised out of engagement by raising the knob of the control lever, such knob being fast to the inner rod 25 and not to the lever 14 proper.

Title: A process for the manufacture of co-polymers from vinyl esters and vinylidene compounds by polymerisation in emulsion
IPC: C08F2/22
Filed: 1946-01-09
Abstract: Vinyl esters, such as vinyl chloride, and vinylidene compounds, such as vinylidene chloride, are copolymerized in aqueous emulsion, the vinyl ester only at the outset being subjected to polymerizing conditions, the vinylidene compound being added after a substantial part of the induction period has elapsed but before any polymerization reaction commences.  The induction period may be shortened by using a higher temperature for the first step and then lowering the temperature for the actual polymerization. Plasticizers such as dibutyl phthalate and sec.-octyl phthalate, fillers and colouring matter may be added before, during or after polymerization. Hydrogen or benzoyl peroxide may be used as catalysts and sodium cetyl sulphate as emulsifier.  Solvents for various copolymers are butyl acetate and xylene mixtures, ethyl acetate, acetone and dichlorethane.  Films may be cast from the solutions.  The copolymers may also be after-halogenated, e.g. chlorinated.  The Specification as open to inspection under Sect. 91 comprises also obtaining copolymers of a uniform constitution from a mixture of copolymers of varying constitutions by fractional solution and/or fractional precipitation, ultra centrifuging or dialysis. Mixtures of acetone and methyl alcohol may be used in the fraction solution.  This subject-matter does not appear in the Specification as accepted.
