Abstract: A B S T R A C T            The invention is based upon a mounting for heated vessels (1), more particularly for tilting, steel-plant converters, the weight of which is absorbed, while allowing for thermal motion, when the vessel is upright, by means of tension-elements (13) in parallel with the central longitudinal axis (12) of the vessel and, if necessary and when the vessel is horizontal, by means of flexible tension-elements (13) running transversely or perpendicularly to the central longitudinal axis of the vessel, the said tension-elements being pre-loaded and secured to stationary or tiltable mountings (8).  In the case of the loading arising when the vessel is horizontal, in order to avoid an unduly rigid transverse attachment, consisting of an insert-pin on the support-frame (8) and an insert-pin receptacle on the vessel (1), i.e. in order to make it possible for the transverse attachment also to absorb thermal motions without disadvan-tages, it is proposed that the transverse-attachment tension-elements (14a, 14b) be attached in pairs by their one ends (14c) to a vessel-mounting (8) at the side of the vessel and, by their other ends (14d), to a displaceable hollow bearing (15) in such a manner as to transfer tensile force, and that a short support lug (16), projecting into the said hollow bearing (15) be connected, at least centrally, to the wall (2) of the vessel.  In the case of an interchangeable heated vessel, the short support lugs (16), with their axes running in parallel with the central longitudinal axis of the vessel, are adapted to slide in and out of the said hollow bearing (15).

Abstract: ABSTRACT OF THE DISCLOSURE, The invention relates to an electrode intended, for example, for electro-cardiogram examinations, and capable of being held in position by suction.          Vacuum conditions are created through a hose or tube, through which a measuring conductor is drawn.  The electrode comprises an inflexible backpiece, an intermediate component made of an elastomeric material, and an electrode plate, preferably made of a. silver-coated plastics.  The intermediate component includes a relatively inflexible sealing ring which, in the operative state of the electrode, supports against the skin of a patient via a sealing lip and against the opposing side of the back-piece.  The electrode plate is firmly connected to the backpiece, while the sealing ring carried by the intermediate component is movable and can be readily sprung away from the backpiece via a. resilient member, When no load is exerted on the lip-side of the ring and the ring is thus urged outwardly, a vacuum valve is closed automatically through the inter-mediate component, and is re-opened when the electrode is pressed against the surface of the skin, whereupon the electrode is held firmly by suction.

Abstract: MICROPROCESSOR BASED TWO SPEED MOTOR CONTROL INTERFACE            ABSTRACT OF THE DISCLOSURE            A two speed motor control comprises push buttons that can be activated to start, stop, select a high start of speed or select a low start of speed for the motor.  The high and low selector buttons can be used to transfer between high and low speed operation for the motor.  Units in the form of AND gates for example can be provided with inputs to establish permissive conditions for a motor start up or speed change operation.  These automatically avoid overheating the motor or starting the motor during an inappropriate condition of equipment connected to the motor.  Start up and speed selection is achieved without the operator having to verify the existance of appropriate conditions.

Abstract: ABSTRACT OF THE DISCLOSURE      Disclosed  herein are  an  improved method  and  apparatus  for continuously  embossing  a  repeating  pattern  of  precise  detail,  in particular,  cube-corner  type  reflector  elements,  on  one  surface of a single  sheet or on one surface of a laminate of transparent thermoplastic materials,  to form retroreflective  sheeting.  A con-tinuous embossing tool  in  the  form of a flexible  thin metal belt or  cylinder has  on  its  outer  surface  an  embossing pattern which is the reverse of the precision optical pattern to be formed.  The embossing tool is continuously moved at a predetermined speed along a  closet  course  through  a  heating station  where  the  temperature of a portion of the embossing tool is raised to be above the glass transition  temperature  of  the  sheeting or  laminate and a  cooling station where  the heated portion of  the  embossing tool  is  cooled while in a relatively planar condition to be below that glass transi-tion temperature.  The sheeting is continuously moved at the predeter-mined speed from a supply thereof into engagement with the embossing pattern  on  the  tool  and is  pressed  there-against  continuously at a plurality of pressure points sequentially spaced along the heating station, with the one surface of the sheeting confronting and engaging the embossing pattern until the sheeting is raised above its glass transition  temperature  and  conforms  to  the  embossing pattern  on the  one  face.   The  sheeting is maintained  in engagement with the tool until the tool passes through the cooling station and the sheet-ing is lowered below its glass transition temperature and the pattern solidifies.  The sheeting thereafter is stripped from the tool and 2. next passed through a reheating station where the embossed sheeting is  heated  to  an  annealing  temperature  where  the  stresses  formed in  the  thermoplastic  material  during  embossing  and  cooling  are relieved, while preserving and enhancing the precision optical pattern previously formed.

Abstract: PROGRAMMABLE CONTROLLER ("PC") WITH IMPROVED BOOLEAN PROCESSOR                ABSTRACT OF THE DISCLOSURE           A very fast and efficient Boolean processor ("BP") (20) capable of compiling a full range of diagrams or expressions in ladder, logigram, and Boolean with a small but powerful instruction set.  The BP includes an instruction decoder (34), combinatoric logic (35), a T-register (42) which holds the temporary results of a sequential AND operation, an N-register (43) which holds the initial Boolean value of T, a Binary Accumulator Memory ("BAM") (40) which is used as a scratchpad for a program which evaluates a ladder or logigram diagram or a Boolean expression, a source address ("S") in BAM (40) from which an initial operand is taken, a destina-tion address ("D") in BAM (40) in which the result of an operation is stored, and a destination address regis-ter ("DAR") (45) in which the destination address is stored.  The instruction set includes a subset of input instructions and a subset of structure instructions. The operand (I) of an input instruction is an address in IOIM (25).  The operands (S,D) of a structure in-struction are source and destination addresses in BAM (40).  Each input instruction reads the value of a bit from IOIM and has the effect of logically combining this bit value with the value held in the T-register and possibly with the destination bit in BAM.  The struc-ture instructions cause operation on the pair of ad-dresses S and D, and either describe the structure of the diagram to be compiled or permit the performance of logical functions between nodes in the diagram.

Abstract: Abstract of the Disclosure A sliding clip for a floating standing seam roof for allowing buckling of the roof panels to relieve exces-sive thermal expansion.  The relative arrangement of the stops which limit the motion of the upper clip portion in respect of the lower clip portion is asymmetrical to allow a greater admplitude of motion of the upper clip portion toward the fixed ends of the roof panels caused by contrac-tion than is permitted toward the floating ends of the roof panels caused by expansion.  This prevents destruction of the clips or of the fastener for the fixed ends.  It also prevents rupture of the panels themselves at their fixed ends.
