Abstract: A pivotable adjustment mechanism is provided herein for the connection of two mutually moveable members. Such members can be a seat portion and a base support portion of a chair, two cooperating, shaftforming members of an apparatus, a machine, etc. The adjustment mechanism includes two concentric rings suspended according to the Cardan principle. The two rings each have a torsion bar disposed along a diameter of and securely fastened to its ring for adjustment of the latter, the two torsion bars being arranged at right angles to each other. A first member is fastened to the outer ring which is suspended by rotatably mounting the ends of its torsion bar in brackets secured to the inner ring which is axially displaced of the outer ring. The inner ring is suspended by rotatably mounting the ends of its torsion bar in a bracket secured to a second member of the chair, apparatus, machine, etc. The torsion bars of the outer ring are secured at their centers against rotation relative to the inner ring and the bracket secured to the second member respectively. This mechanism using the Cardan principle provides a more robust construction with the use of torsion springs which provides a longer lifetime for the springs and less noise in the springs during use.

Abstract: Abstract of the Disclosure:     A standard industrial process is the formation of a varnish layer on a printed surface.   The use of a hydrophobic ink on a hydrophilic surface leads to inefficient coating when a water based varnish composition, for example a dispersed acrylic copolymer, is used.  The standard of varnish coating is improved by incorporating an auxiliary film forming material, for example caesin, capable of raising the critical surface tension to the hydrophobic inked areas."

Abstract: WGT:SLW     METHOD FOR MANUFACTURING AN EMBOSSES VINYL SURFACE COVER ING           HAVING A CLEAR PHOTOPOLYMERIZED COATING     ABSTRACT  OF THE DISCLOSURE         An improved method for manufacturing an embossed thermoplastic surface covering having a clear, durable, tough, mar-resistant photo-polymerized wear layer is described.  One conventional method for forming such a surface covering involves passing an embossed substrate beneath a curtain coater containing a 100% reactive photopolymerizable coating to apply about 2 to 5 mils of coating and then curing the coated substrate by passing it beneath a source of ultraviolet radiation.  A disadvantage in this method resides in the fact that, in those areas deeply embossed, the coating being applied by the curtain coater, which is highly viscous, traps air bubbles beneath the surface of the coating adjacent the leading edges of the valleys which first pass beneath the curtain coater.          We have overcome this difficulty by prewetting the valleys of the em-bossed substrate with a liquid consisting essentially of an acrylate or mixtures of acrylates together with sufficient photoinitiator to initiate polymerization when the coated substrate is subjected to ultraviolet radiation.

Abstract: ABSTRACT A control unit for a converter has a circuit for the formation of a periodic control signal having a given pulse pattern including a memory in which code words designating the position of the switching pulses (flanks) of the control signals in one period or subperiod of the converter voltage, divided into a number of increments, are stored.  Address input of the memory is connected to an addressing unit which generates addresses associated with the pulse pattern of the control signal and with the switching pulses within the pulse pattern.  A digital comparator compares the code words at the out-put of the memory with the count of a counter.  Whenever the code word and the count are in agreement, the comparator triggers a pulse stage generator whose output signal represents the control signal and advances the addressing unit to the next address.  The invention makes possible the formation of control signals independent of circuit for different converter types and converter circuits is thus made possible.
