Patent EP-0002326-A1 (EP)
Inventor: HARDWICK HARRY FLEEMAN
IPC: B31B29/84
Filed: 1978-11-14
Abstract: A valve sack is made from tubular material whose opposed longitudinal edges have been gusseted. There is formed in one of the gussets an aperture (S) which extends along the gusset for a distance appreciably less than the width (D) of eventuat sack. The outer longitudinal edges of the gusset are then sealed together, either directly or via a further sheet of material, over a distance greater than the length of said aperture, to form a tube running along one longitudinal edge of the material. The material is then sealed together along two lines which run across the material and are spaced apart to define the width of the eventual sack. One end of the tube is sealed off. A further aperture overlapping the first mentioned aperture if formed in the tube.

Abstract: An aerator for the treatment of liquid by immersion in the liquid to form in the liquid a liquid stream and introduced gas bubbles. The stream is to be produced with efficient use of power to have sufficient bubbles small enough to avoid waste by bubbles reaching the surface too quickly. The areator has a pressure chamber (49), with a liquid inlet and gas inlets (422) positioned between the liquid inlet and a restricted outlet throat (47) associated with a chamber wall surface (44) arranged to direct an outlet stream deflected from the liquid inlet direction. The aerator can be formed without immersed moving parts by two tubes, a smaller inner one (41) expanding towards an outer larger one (42) to define the throat and pressure chamber and wall surface. The gas supply is applied through holes large enough to resist algal obstruction at a position where the gas and water enter a part of the pressure chamber of reducing cross-section for subsequent deflection out of the throat.

Abstract: The invention provides a process for reducing the fiamide content of imidazolines having the formula:-
     wherein R represents an aliphatic group having from at least 4 carbon atoms and R 1  represents an alkyl or alkenyl group having from 1 to 4 carbon atoms. 
     The mixture of imidazoline and diamide is reacted with a primary of secondary amine which deacylates the diamide to an amido-amine. The product of this deacyla- tion is an imidazoline solution which remains clear even on prolonged storage. 
     The imidazoline is produced by reaction of an acid RCOOH with a diamine NH 2 (CH 2 ) 2 NHR 1 . Preferably this diamine is used as the deacylating agent.

Abstract: Rotary valve controlled internal combustion engine and method for facilitating the relative motion between the elements of a sliding valve. This apparatus has a flow duct or a channel (304) and a rotary valve device (314) connected therein. Intermittently operating sealing elements (sliding plates) (332, 334) for preventing a flow through the channel have a sealing surface which can be brought intermittently into an immovable sealing position transversely over the channel (304). Special devices (358-362) are used to displace the sealing surface as a function of the method of operation of the rotary valve device (314) into this stationary sealing position with respect to the channel (304) and out of this sealing position, in order to improve the sealing, in operation of the rotary valve device (314). A device (394-408) for the oil-free lubrication of the sliding plates which can move with respect to one another is furthermore provided. The invention furthermore provides for a method for facilitating the relative motion between the elements of a sliding valve. <IMAGE>

Abstract: A process for separating the individual optically active isomers of cis- or trans-cyclopropane carboxylic acids which comprises the step of treating an aqueous solution of a soluble salt of the recemate or diastereoisomeric mixture with just sufficient of a suitable optically active amine to cause precipitation of one isomer or diastereoisomer of the cyclopropane carboxylic acid as the amine salt, whilst substantially all of the other isomer (or isomers if more than two are present in the mixture) remains in solutionas the soluble salt. The process can be used to separate (+)-cis-3-(2-chloro-3,3,3-trifluoroprop-1-en-lyl)-2,2-dimethylcyclopropane carboxylic acid from a (±)-cis-mixture.

Abstract: Molding apparatus for injection-compression molding thermosetting materials comprises an injection nozzle assembly (17) controlled at a temperature high enough to maintain thermosetting molding material within the nozzle in a plasticized state and low enough that no substantial curing or setting-up of the thermosetting molding material takes place. 
     In the injection state, a movable platen assembly (39,41) is positioned with its mold faces (27) in close proximity with aligned mold faces (25) on a stationary platen assembly (29,31) to form partially open mold cavities (23) into which thermosetting molding material is fed in a plasticized state through the nozzle member (17), through runner channels (21) from the nozzle assembly into the partially open, heated, mold cavities (23). 
     Subsequent complete closure of the heated mold cavities cuts off further feed of thermosetting material by closing off the runner channels with the thermosetting material within the confines of the mold faces being pressed and heated to a curing temperature.

Abstract: Open-air theatre consisting of a performance area for the actors and rows of seats arranged in front of the said area, which theatre takes account of the demands of modern theatre, which requires a flexible association of stage areas and audience areas, and permits experiments with space by virtue of easy variability, even during rehearsals, without special technical means, making possible a daily alteration of the audience-actor configuration. The object is essentially achieved by a mobile theatre comprising seats for the audience and stage areas (1) for the actors, with frameworks (2) which are arranged on one or more sides of the stage area (1) and into which platforms (3) can be placed one above the other at an appropriate spacing, on which the seats for the audience are arranged and which are provided on one longitudinal side with stair frameworks (4) into which panels (5) can be placed as steps. At the same time, it is possible to use the stage area as the audience area and to use the frameworks as the stage area. <IMAGE>

Abstract: A pulse arc welding machine includes a consumable wire electrode (12), a wire feeding unit (14) for the wire electrode, a base current source (9), and a pulse current source (1, 2) for supplying a pulse current superposed on the base current. The quantity of heat applied to the electrode (12) is corrected by comparing an output detection signal produced by an arc sensor (38) with a preset arc voltage and then producing a pulse width instruction signal in response to the difference signal for setting the pulse width of the pulse current. When the detected arc voltage is large, the quantity of heat applied to the electrode (12) by the welding current is decreased and the wire feeding speed is increased, while when the arc voltage is small, the quantity of heat applied to the wire electrode is increased and the wire feeding speed decreased.
