Abstract: "LOAD SENSING GEARBOX"                        Abstract A    universal    load    sensing   gearbox integrating a safety mechanism for use, for instance, with motor driven closures,   such as garage doors, barriers and gates,  includes a housing which encases a worm slidably mounted on an input shaft and adapted for  rotation  therewith.      The  input  shaft  is connected with the motor driving the closure.    The worm is engaged with a worm gear which is mounted on an output shaft which is connected with the closure. Dished  washers  are  provided  generally  around  the input shaft at both ends of the worm to urge the worm in a central meshed engagement with the worm gear.  A motion transmission device is provided on the worm and  is  adapted  to  slide  therewith  to  detect  a longitudinal movement thereof and to transmit this movement to an actuating device which is adapted to stop and/or reverse the motor.  Therefore, sufficient resistance  to  the  rotation  of  the  output  shaft resulting, for example, from the closure encountering an object pressure,  causes the worm to be displaced along the  input  shaft  against  the  dished washers along with the transmission device.    A sufficient movement  of  the  transmission device  causes  the actuating  device  to  trip  a  limit  switch  which triggers the stoppage and/or reversing of the motor. The  load  sensing  gearbox  is  also  intended  for agricultural applications using reducing gearboxes, for  actuating  aircraft  wing  flaps,   for  conveyer belts, etc.

Abstract: The object of the present invention is a novel and simple process forthe production of 1,2-diacyl-sn-glycerols, wherein the acyl groups may be the same or different. According to the invention D-mannitol is reacted with benzene boronic acid or a derivative thereof to form a D-mannitol- monobenzeneboronate which compound is acylated either to form, after removal of the benzeneboronate protective group, a 1,2,5,6-tetraacyl-D-mannitol with four identical acyl groups, or is acylated selectively in two stages, by first acylating the 1,6-hydroxy groups of the boronate protected D-mannitol to form, after removal of the boronate protection, a 1,6-diacyl-D-mannitol, which then is repeatedly reacted with a benzene boronic acid or a derivative thereof and then acylated in the 2-and 5-positions. After removal of the boronate protective group, the tetra-acylated D-mannitol obtained either in the one-stage or two-stage process is split by oxidation to form a 1,2-diacyl-glyceraldehyde which in turn is reduced to the corresponding 1,2-diacyl-sn-glycerol. By means of the invention it is thus possible to prepare 1,2-diacyl-sn-glycerols in which the acyl groups can be the same or different.

Title: Method for the preparation of polydicarboxysaccharides, and substitutes for phosphates in detergents, based on the polydicarboxysaccharides
Inventor: BESEMER ARIE C
IPC: C08B37/00
Filed: 1990-11-09
Granted: 2001-04-24
Abstract: A method for the preparation of polydicarboxysaccharides is provided wherein polysaccharides, such as starch and starch derivatives, are oxidised in the presence of hypobromite and/or hypoiodite and a low oxidising agent concentration is maintained during the oxidation reaction. The low concentration of oxidising agent can be maintained by adding the oxidising agent during the oxidation reaction. The hypobromite or hypoiodite is preferably formed in the reaction medium by oxidation of a catalytic amount of bromide or iodide, either by addition of hypochlorite or by passing an electric current. The product obtained by the method has good calcium and magnesium binding properties and is biodegradable, and thus it is very suitable for use as a builder in detergent compositions.
