Title: Process for the prepn. of cell-free penicillin-acylase by fermenting a strain of E. coli which produces this enzyme. The intracellular enzyme is separated form
IPC: C12P37/00
Filed: 1969-02-14
Abstract: Prepn. of cell-free penicillin-acylase by fermenting a strain of E. coli which produces this enzyme. The intracellular enzyme is separated from the culture liquid at controlled temps. between 0-50 deg.C by fast removal of the cell material through a slot or opening at a pressure of at least 500 psi but below the pressure which would badly tear the cells. The removed cell material is then stirred in water for 0.1-5 hrs. at 10-50 deg.C to dissolve the enzyme; this is extracted from the inactive cell material in aqs. soln. The cell-free enzymes are used for the prodn. of 6-APA and are esp. suitable for direct removal of side-chains of natural penicillins, esp. the side-chains of benzyl penicillin. The enzymes may be used as starting materials for chemical modification of the enzyme, giving products with higher activity and/or wider technical application.

Title: Sealed container with pouring lip for liquids - or powders
IPC: B65D5/06
Filed: 1969-03-21
Abstract: Container is parallelepiped shaped and of square section, and has a roof-shaped top closure with 2 symmetrical slopes. The rigid outer envelope has a bottom made of 4 triangular sections automatically locked together by integral notched feet and are mutually imbricated. An inner impermeable envelope has a sealed bottom and is of flexible plastics whose natural depends on the eventual contents; it is glued at least to the top part of the inner walls of the outer envelope. The lip is integral with the upper part and is formed in the axial prolongation of the roof as it is sealed; it is a pyramidal projection with a triangular base, and its top point has incisions to facilitate its cutting away for the pouring, orifice. The lower triangular side of the lip forms the pouring plane, whose slop is the same as that of the roof sides. Full containers can be stacked without loss of space, as the lip imbricates with one of the roof slops of a neighbouring container. The containers can be grouped in at least fours and then in multiples of 2 and 3, taking account only of the orientation of the lip.

Title: Flocculating agent dose regulation - using clarity of samples as parameter for varying dosing rate
IPC: G05D21/02
Filed: 1972-02-11
Abstract: A method for precipitating suspended particles from a liquor, esp. for separating sludge from a liquid containing it, using a dosed flocculating agent, is carried out by removing samples at intervals from the liquor, containing flocculating agent, flowing into the separator, the quantity of flocculating agent dosed is reduced or increased according to whether the sample clarifies before or after a predetermined period of time, as the suspended particles sink. In a preferred apparatus, samples are removed at intervals from the incoming flow lines, into which flocculating agent has already been injected, the samples are tested by photo-sensitive devices for measuring their clarity in a sample vessel; depending upon whether a predetermined clarity level is reached before or after a predetermined time, a control circuit reduces or increases the dosing rate of flocculating agent.

Title: Recovering pure glycofrangulins - from rhamnus frangula by selective solvent extraction
IPC: A61K31/70
Filed: 1972-02-28
Abstract: Process for recovering glycofrangulins from crude plant material, esp. the dried bark of the alder buckthorn (Rhamnus frangula L.) comprises extracting the material with a solvent mixt. of (i) a 1-3C alcohol and (ii) a 3-6C aliphatic or cyclic oxo and/or oxido cpd.; removing impurities from the extract by adsorption onto an activated polyamide; treating the purified soln. with a non-aqueous, esp. methanolic, soln. of an alkali hydroxide to produce a salt which is then treated with an acid or ion-exchanger, and solvent removed from the final product in the usual manner. Extract is a mild laxative. Process gives a purer product (90-95% consisting of molecules having at least 2 sugar residues bound to emodin) than prior art processes. Extraction solvent has excellent selectivity; most of the impurities (which are foul smelling and cause undesirable side effects) are irreversibly bound to the polyamide, and the process is suitable for large scale operation.
Patent FR-2162230-A1 (FR)
IPC: H01G7/02
Filed: 1972-12-04
Abstract: An electret transducer in which the electret material is an inorganic insulator sheet with electric charges in it and is juxtaposed to an electrode, and either the sheet or the electrode is mechanically deformable to change the distance between the two, thereby changing the electric charge induced in the electrode by the charged electret sheet. In a preferred form, the electret material comprises a multilayer sheet of insulating materials. The method of forming the transducer includes at least the steps of vapor-depositing a thin layer of inorganic material on a substrate and subjecting the exposed surface of the insulating material to a source of electric charge for a time sufficient to implant charges in the insulating material. If the insulating material is to be deformable, it should be deposited on a thin layer of metal which, in turn, has been deposited on a thicker substrate. A spacer layer of metal is deposited on top of the charged insulating material. Thereafter, selected areas of the substrate and of the spacer layer are chemically removed to leave the thin metal layer and the charged insulating material free of support except around the periphery of such open area. The ability of the insulating material to accept and hold a charge may be improved by depositing the insulating material as two separate layers of different materials, one immediately on top of the other.

Title: Refrigeration door seal - with magnetic strip insert having anti-scuffing seal face
IPC: F25D23/02
Filed: 1973-04-26
Abstract: A flexible extruded seal and closure for a refrigerator cabinet, pref. of PVC, and incorporating a flexible permanent magnetic strip. The seal consists of a sealing face section contg. the permanent magnetic strip, which seals against the metallic face of the cabinet or door, which is supported by a flexible bellows section of the extrusion from the base section attached to the other part of the refrigerator. To eliminate problems of scuffing of the seal face, with consequent difficulties in closure and damage to the seal which occur on the hinge side of the door, the seal face section of the seal extrusion has a higher durometer hardness (e.g. 90-95 Shore A scale) than the rest of the extrusion (e.G. 65-70 Shore A scale), thus minimising friction.

Title: Heavy load handling belt - comprises several slings encased in flexible protective coating
IPC: B66C1/18
Filed: 1974-05-27
Abstract: The belt is composed of a number of slings sharing the load between them, the slings being encased in a coating (6) of flexible protective material such as rubber, plastic etc. To prevent the load slipping, the external surface of the belt can be ribbed. Alternatively it can be completely smooth, for use in securing bundles of well tubes, so that individual ones can be slid clear as desired. It can also have coloured external flourescent markings for measurement of lengths etc. The design avoids damage to the load, or to the user's hands due to frayed rope wires, in addition to protecting the slings themselves from wear.

Title: Digital magnetic compass - produces digital measurement of azimuth of given direction with respect to earths magnetic field
Inventor: MANOTTE LOUIS
IPC: G01C17/26
Filed: 1974-10-11
Abstract: The digital magnetic compass comprises a pointer rotated at a constant speed about a vertical axis. Devices generate a first electric signal each time the pointer passes a mark at a certain position with respect to the given direction. Further devices generate a second electric signal when the pointer is in a certain position with respect to the terrestrial magnetic field. A constant frequency oscillator is provided. A pulse counter counts the oscillator pulses between the two electric signals. A device for the second electric signal generation consists of a soft iron bar rotating together with the pointer about the vertical axis, with respect to which it is eccentrically mounted.
