Patent NL-7604706-A (NL)
Title: Test tube vibrator for mixing - with the movement limited by elastic connectors strengthened with fabric
IPC: B01F11/00
Filed: 1976-05-03
Abstract: A vibrator for mixing materials in test tubes has a recess which moves in a circular path. The turning of the recess is limited by two or more elastic connectors installed radially symmetrical w.r.t. the drive shaft. They connect the recess to fixed points on the equipment. A test tube whose contents are to be mixed is pressed into the recess which begins to rotate. The top of the tube is steadied by hand during the mixing. Conventional devices for limiting movement of the recess tend to exert too great a breaking force on the motor as it starts or to be unreliable because they are too flexible. They allow too much noise to be produced. These problems are solved with the present design.

Patent NL-8900102-A (NL)
IPC: C02F3/02
Filed: 1989-01-17
Abstract: The present invention relates to a process for cleaning soil wherein the soil to be cleaned is brought into a layer with a thickness of 1 to 2 m on an impermeable bottom, liquid is spread over the soil and liquid is withdrawn from the bottom side of the soil depot by means of a drainage system wherein the liquid withdrawn from the soil is subjected to a biological and/or physical-chemical purification and the excess of liquid, if any, is thus discarded and the remainder is supplied to the soil again, if desired after the addition of nutrients and/or micro-organisms and/or an extraction agent or detergent. If desired, the soil can be worked periodically. Especially in case of volatile components, air is withdrawn from the soil to remove the volatiles. Air injection is an expedient means to provide additional oxygen in the soil.

Abstract: A sweeping member (5), together with a plate (2) which is to be worked and lies on a layer (4) of resilient material of a table leaf (3), is pressed over a certain distance, the depth of impression, into the resilient layer (4). Subsequently the sweeping member (5) is slid substantially parallel to the supporting leaf (3) over the plate (2) in the direction of the arrow P1, the resilient layer (4) being continuously impressed, thereby causing the plate material (2) to deform at the site of the zone of impression. By moving the sweeping member (5) continuously over the plate (2), that portion of the plate (2) which has already been swept will begin to display a curvature having a certain radius R. By varying the depth of impression, the plate material (2) can be provided locally with different radii of curvature.

Title: Process for preparing dimethilglycil-gluconic acid and salts thereof
Inventor: NASCIMENTO JOSE MARIA DO JUNIO
IPC: C07G13/00
Filed: 1987-09-21
Abstract: A new process for the synthesis of pangamic acid salts (sometimes also referred to as vitamin B15 and more accurately called dimethylglycyl gluconates). This process consists in the esterification of gluconic acid or of calcium or magnesium gluconate with a dimethylglycine hydrochloride in aqueous medium in the presence of phosphoric acid or of sulphuric acid at a temperature varying between 30 DEG  and 70 DEG C; then in the concentration of the esterification product, followed by removal of the inorganic acids by reaction with a water-insoluble amine of high molecular weight. The pangamic acid obtained is then converted into one of its salts by reaction with a carbonate such as, for example, calcium carbonate or magnesium carbonate. The pangamates are useful in medicine for combating various forms of arteriosclerosis.

Abstract: An arrangement in shelf, tray, drawer structures (10) or like structures of the kind which can be moved between an inserted position, for the storage of articles, e.g. packages such as drugstore packages, and a position of use in which the packages can be removed from the trays or the like. The trays or the like are mounted on brackets (12) which are fitted to a frame structure (22) in a manner to enable the brackets to be adjusted between mutually different positions, and optionally to be removed from the frame structure. The trays, drawers or the like include catch means (36) which are intended to latch the trays or the like in a fully inserted position in the brackets (12). The brackets (12) can be adjusted on the frame structures (22) such as to extend horizontally or at an inclined angle. The trays or drawers and/or the brackets are configured so that when the brackets (12) are in their horizontal positions the trays or drawers cannot be inserted to their full extent, thereby preventing the catch means (36) from coming into operation. This can be achieved, for instance, by inclining the end wall surface of respective trays, such that the end wall will slope obliquely inwards to the structure (22) from the bottom of respective trays to their upper side. When the brackets (12) are adjusted to their inclined positions, the trays or the like (10) can be fully inserted and thus latched by the catch means (36).
