Abstract: SPREADER FOR PARTICULATE MATERIAL                 Abstract of the Disclosure In a spreader of the type used for spreading particulate material onto a roadway and comprising an upper hopper having a lower material discharge chamber terminating in a lower dis-charge opening, a rotatable spreader element below the discharge opening and a valve mechanism between the discharge chamber and the spreader element for controlling flow of material from the chamber to the spreader, there is provided an arrangement for shifting the valve mechanism between an opened and closed position in response to the direction of rotation of the spreader element.  When the spreader element is rotating in one direction, the valve mechanism is automatically opened. When the spreader is rotated in the opposite direction the valve mechanism is automatically closed.  This valve operating feature is accom-plished by transmitting force through the particulate material within the discharge chamber of the spreader device so that no physical connection is provided between the motor and the valve shifting arrangement.

Abstract: A dwelling for cold climates in the shape of a portion of a right circular cons cut along a longitudinal plane perpendicular to the base of the cone.  The cons portion is laid on its aids and the longitudinal plane forms a floor for the dwelling, which is of triangular shape.  The base wall of the dwelling is arc-shaped and is provided with a plurality of windows.  The outside and inside surfaces of the roof and side walls of the dwelling converge in the direction of the apex portion of the dwelling.  The dwelling is oriented such that its apex portion faces the direction of the prevailing winds, which are generally north or northwest in the cold regions, whereby the base wall faces the sun.  There is a minimum heat loss due to the wind and the light rays entering the windows of the base well are reflected onto the floor by the inclined inside surfaces of the dwelling.

Abstract: ABSTRACT Electric household blender having a base enclosing a motor to drive the tools of an auxiliary unit such as a carved element, wherein the auxiliary unit is anchored by lock bars arranged thereon to bolts provided on the base.  The bolts can be rotatably moved together with a ring mounted on the base for the purpose of locking, which ring, in turn, cooperates with an operating switch to turn the drive motor on and off and with a positioning member, lock rod and lock fork.  The lock bars are either rigidly arranged on the auxiliary unit and formed in two pieces, or formed as one-piece, double-bent, flat pushers mounted in a movable manner in the housing of the auxiliary unit.  The operating switch and the lock bars can only be activated when the lock bolts have first entered into the recesses or lock bar in such a manner that the auxiliary unit is nonremovably locked in place.

Abstract: Abstract of the Disclosure Electrothermal printing apparatus includes a thin, planar, endless ribbon of electrically resistive material having a thin conductive layer on an outside surface thereof and a row of spaced-apart, conductive styli individually selectively coupleable to the conductive layer through a voltage source and disposed in contact with the ribbon at the inside surface thereof opposite the conductive layer.  Momentarily coupling selected ones of the styli to the voltage source produces heating of discrete areas of the resistive ribbon adjacent the momentarily coupled styli.  The ribbon which is mounted on one or more rollers moves relative to the styli and in the same direction and at the same speed as an adjacent length of thermally sensitive paper so that discrete areas of the ribbon heated by the styli remain in contact with the thermally sensitive paper long enough to color discrete areas of the paper adjacent the heated discrete areas of the resistive ribbon.

Abstract: Abstract of  the Disclosure The ergonomic chair comprises at the upper end of the chair column, a supporting arm on which the front end of the seat supporting frame is articulated for pivoting vertically. At the rear end of the seat supporting frame, a back rest is connected to the seat supporting frame and the supporting arm by means of a movement guiding and return mechanism so that an alteration in the inclination of the back rest automatically causes a proportional alteration in the inclination of the seat supporting frame. The movement guiding and return mechanism is divided into two structural units which are separate in construction. The one is a linkage mechanism which is effective between a back-rest connection construction, the seat supporting frame and the supporting arm, with a movement lock which is effective when the chair is in the position of rest. The other structural unit is constructed in the form of a spring mechanism which can be locked and which applies a force to the chair column between the back-rest connection construc-tion and the supporting arm, through which the back rest and the seat supporting frame are restored from a backward-ly inclined position into a normal initial position.

Abstract: ABSTRACT OF THE INVENTION The invention provides a process for the granulation of sulfur, consisting in the solidification of liquid sulfur on a counter-current stream of air in a column, characterized in that liquid sulfur is introduced into a vertical air stream having the linear velocity increasing downwards, from a velocity lower than the critical velocity of sulfur dust in the sprinkling zone to a velocity higher than the critical velocity of the formed granule in the zone of intensive cooling.  As an additional cooling medium, water may be introduced into the air stream in the form of a mist.  The variable air velocity may be achieved by varying the cross-sectional area of the air stream.  The process according to the invention selectively produces granules that have any grain characteristic, smooth spherically formed surfaces and high mechanical strength.

Abstract: ABSTRACT OF THE DISCLOSURE         For reducing the amount of water consumed, the supply of water to the cutting head of a cutting machine is released only when different operating conditions simultaneously occur.       The process provides for the release of the supply of water to the cutting head only with the switching-on of rotational movement of the cutting head and to make the water supply available only when at least one further operating condition such as, for example, movement of the cutting arm or movement of the machine simultaneously occurs.  The apparatus for effect-ing this process comprises a device for switching-on a water pump, said device being coupled with a device for switching-on the rotational drive of the cutting head.  For this purpose, a series of control pistons are arranged within a common cylin-der, the working spaces of each individual control piston being connected via conduits with the working spaces of the associated hydraulic assemblies for the movement of the cutt-ing arm  and, the machine.  The control pistons are coupled one with the other in direction of the pressure supplied and biassed in opposite direction by a spring.  Movement of one of the control pistons which control pistons can be moved in-dependently one from the other, together with the water pump being switched-on, this effects a release of supply of water to the cutting head.
