Abstract: Novel polycationic or polyguaternary ammonium ionenes, which generally are hygroscopic, and processes for their preparation, are described. The compounds are useful as conditioning agents for skin, hair, textile products and powders.

Abstract: The invention provides a junction coupling for branching a flow of fluid from a pipe or conduit. The junction coupling is essentially C-shaped and is dimensioned partly to surround such pipe or conduit. Opposite limbs of the C-shaped member carry, on the one hand, an outlet duct and on the other hand means for securing the coupling in position on the pipe or conduit. The outlet duct is alignable with an aperture in the conduit wall and adapted to receive a branch conduit. The dimensions of the C-shaped member are such that the coupling may be engaged over the pipe or conduit only at the location of the aperture therein.

Abstract: This invention provides a garment design aid. In one embodiment the invention comprises a bodice design aid having a rigid spine, a rigid rib slidable along the spine and projecting therefrom and a number of template panels two of which are used at a time, together with the rib and spine, to provide a pattern for the bodice. The panels are slidably secured to the rib and spine so that the size of the pattern may be varied. The position and shape of darts is indicated by members that are pivotally attached to the template panels. In another embodiment the invention comprises a pants design aid which has three template panels that are slidably interconnected to cater for size variations. This aid further has a pivoted member to vary the crutch depth of the pants and two further pivoted members for varying the hip size of the pants.

Abstract: In a civil machine comprising a working tool provided on a vehicle with a travelling mechanism and a drive therefor, an automatic control system comprises a stroke detector for detecting the amount of stroke of a lifting cylinder operating to move the working tool up and down, an inclination angle detector for detecting the inclination angle of the vehicle, an arithmetic unit for obtaining data representative of the height of the working tool from the detection signals of the two detectors, and a control for operating the lifting cylinder by using the data to control the position of the working tool with high accuracy.

Abstract: An apparatus for the mass compensation at a machine driven by means of a crank drive including a crankshaft, especially a punch press or stamping machine, comprising at least one compensation weight which is connected with a piston or cross-head and the crank drive in order to realize a mass compensation both of the oscillating masses and of the rotating masses. A double-lever is hingedly connected by means of its one end with the compensation weight in order to realize mass compensation of the rotating masses and is hingedly connected by means of its other end with the crank drive via a first guide or link. The one end of the double-lever is directly connected at the compensation weight, and an intermediate bearing means of the double-lever is hingedly connected via a second guide or link, directed towards the side of the crank shaft, with the machine housing or a component fixedly connected therewith.
