Title: Process for the preparation of polyisocyanates containing urethane and biuret groups
Inventor: BOCK MANFRED
IPC: C07C275/62
Filed: 1977-09-14
Granted: 1980-08-12
Abstract: Abstract of the Disclosure The present invention is concerned with a process for producing biuret polyisocyanates and the polyisocya-nates so produced.  These isocyanates are produced by the reaction of at least about a four fold molar excess of a diisocyanate having aliphatically bound isocyanate groups with amino alcohols having a particular structure at a temperature between about 90 and 200°C.  The amino alcohols contain at least three carbon atoms, have their hydroxyl and amino groups separated by at least two carbon atoms, and may contain urea, urethane, ether or amino bonds.  The present invention is also concerned with a process for producing two component and one component moisture curing lacquers using the biuret polyisocyanates of the present invention and the lacquers 80 produced.

Abstract: Abstract In a method of stabilising, by means of a stabilising machine adapted to inject a stabilising agent into the ground, a ground surface whose bearing capacity is so low that it is unable to support the stabilising machine or can only support said machine with difficulty, there is used a stabilising unit supported by the drive or transport unit of said machine in front thereof as seen in the drive direction. The stabilising unit has a width which exceeds the width of said drive or transport unit. The stabilising agent is introduced into the ground to a depth of such magnitude, and the machine is driven at such a speed that the ground is sufficiently stabilised by said stabilising agent introduced thereinto to support the whole of the stabilising machine. The stabilising unit may be partially supported by lifting and/or carrying arms of the drive unit and partially by separate ground-engaging tracks or wheels arranged between said unit and said drive unit.        The means for introducing stabilising agent into the ground may be provided with support surfaces arranged to engage the surface of the ground so as to assist in supporting the weight of said unit.        The invention also concerns a stabilising unit for carrying out the method and having means for connecting it to a tractor or a similar vehicle so that it is supported in front thereof.

Abstract: Abstract of the Disclosure The invention provides a trim unit for use, for example, as a valance, or for application to sliding and bifold doors to screen the unsightly gap that usually is left between the bottom edge of the door supporting channel and the top edge of the door or doors.  The unit consists of a U- or L-shaped base member having a first portion that is fastened in some convenient way to the ceiling or door header and a second downwardly-extending portion that extends downward when the unit is installed. A supplementary movable member in mounted on the second portion and can be adjusted in its vertical position thereon.  Thus in the case of a door trim unit the supplementary member can be moved to  screen the gap between the bottom edge of the channel and the top of the door without fouling the door as it is opened and closed. This gap cannot be predetermined and may be changed, e.g. when carpet is installed.   In the case of a valance trim unit the supplementary member can be moved to the position that gives the desired vertical depth to the valance.  The connection between the second vertical portion of the supplementary member may be, for example, by rivets or by nuts and bolts so that they are friction-ally engaged together against relative movement.  In other constructions struck-out parts of the base member frictionally engage the supplementary member, or the supplementary member is of U-shape and frictionally embraces the base member.

Abstract: ABSTRACT OF THE DISCLOSURE            In a household machine for the production of food pastas, the improvement comprising a shaft mounted for rotation about a horizontal axis within a pasta mixing vat which shaft has a set of radially extending kneading elements detachably secured to said shaft.  The dimensions of the shaft and elements and the spacing between the elements are chosen so as to provide a homogenous pasta mixture which avoids adhesion or encrustation of the pasta mixture around the shaft and bases of the elements.  The shaft and kneading elements are preferably smooth and convex surface so that they can be quickly and thorougly cleaned.  In addition, the shaft and kneading elements have no specific surfaces for guiding a pasta mixture and they drag the ingredients into a rotary motion which promotes the formation of lumps.  These lumps constitute true and proper nucleii of initiation of the mixture, which gradually expand and little by little incorporate all the ingredients.  The pressure which arises between these nucleii of the mixture becomes too great for them to move freely without mutual interference.  However, these pressures involve mainly the various parts of the mixture, without exerting excessive forces on the shaft and kneading elements, in view of the relatively small area of the kneading elements.  Thus, the machine can be operated with low-powered motors. In particular; the arrangement of the kneading elements on the shaft results in negligable axial thrust on the shaft.

Abstract: ABSTRACT:          A high voltage transformer, comprising a secondary winding of coils which are wound one on top of the other and which are electrically interconnected by diodes which are connected in the same rectifying sense.  Each coil consists of a number of series con-nected sub-coils, each of which consists of a first layer of turns which contact each other, and a second layer which comprises a smaller number of turns.  The first layers of two successive sub-coils directly con-tact each other, the second layers being separated by a clearance having a width equal to the wire thickness. Compared with prior art transformers, in which each coil is composed of a single layer of turns, the high voltage generated per coil of this transformer is higher, so that fewer coils and diodes are required.

Abstract: Abstract of the Disclosure Feeder apparatus is provided for delivering a pre-determined amount of feed to hogs and like live-stock.  The apparatus includes a feed transporting and dispensing conveyor with which are associated a plurality of feeder units; each unit receives and temporarily stores the feed.  Each unit includes a feed receiver body.  A boot extends from the body and defines a dis-charge opening.  A pear-shaped stopper valve carried in the boot fits into and onto the discharge opening to obstruct the flow.  A stopper valve pull system acts to draw the stopper valve away from the discharge opening, thereby permitting feed flow; if desired, this pull sys-tem can be connected to a timer so as to discharge the feed at a pre-selected moment.  The stopper valve in-cludes a semi-spheroidal element adapted to fit into and onto the discharge opening and a conical element adapted to be drawn through the feed pile so as to discourage feed bridging and hang-up within the feeder unit body.          A discharge tube extending into the feeder unit body includes an extensible and retractable bellows member for varying the height of the feed pile to be collected within the feeder unit.

An apparatus for reading a disk-shaped record carrier, the radial scanning position being controlled with the aid of a first servo control loop, which con-trols a positioning member for the read element depending on a control signal which is read from the record carrier. If this control is disturbed  a second servo control loop is rendered operative. This second servo control loop com-prises a position indicator for supplying a position sig-nal which is representative of the radial position of the positioning member, a memory circuit for storing the value of this position signal at the instant of failure of the first servo control loop, and a differential amplifier for applying a control signal to the positioning member, which signal corresponds to the difference between the instantaneous and the stored value of said position sig-nal. Furthermore, there is provided a control circuit for changing-over between the first and the second servo con-trol loop and vice versa depending on a built-in criterion.
