Abstract: ABSTRACT A heating boiler comprises separate combustion chambers for oil and solid fuel.  The oil combustion chamber can be connected directly to flues in contact with water via an afterburning chamber common to the two chambers. The connection between the oil-combustion chamber and the afterburning cham-ber can be shut off by a damper while a connection is opened between the oil combustion chamber and the solid fuel combustion chamber via  n ash compart-ment and a grate under the solid fuel combustion chamber.  Through the ar-rangement with the damper a number of possible variations can be obtained depending on the actual heat requirements.

Abstract: ABSTRACT OF THE DISCLOSURE         A wood burning stove comprises a fire chamber of which the upper part is constituted as a heat exchanger.  A primary air supply is provided as is a secondary air supply, the secondary air supply permitting air to be mixed with the gaseous products of combustion to support complete combustion of those gaseous products.  Both air supplies have dampers, the damper of the secondary air supply being automatic and opening as the damper of the primary air supply is closed.  The secondary air supply comprises an inlet manifold  interconnecting a plurality of tubu-lar elements which form a fire supporting grate, the tubular elements leading the secondary air beyond the fire to a region in which mixing of that air with the gaseous products of combus-tion is effected, secondary air passing through the tubular elements being preheated by the burning fuel supported on the grate.

Abstract: ROLL-WAVE SHEET SEPARATOR STRUCTURE                    ABSTRACT OF DISCLOSURE          A roll-wave sheet separator is provided which comprises means for supporting a stack of sheets and sheet separating means mounted adjacent to the stack which comprise a rotatable shaft having a helical peripheral thread coaxial with the shaft, and a follower rotatable around the shaft which follows the helical thread to move along the shaft axis.  The follower supports at least one circular element which is pref-erably freely rotatable.  The apparatus further includes means for rotating the shaft in one direction to drive the follower and its supported circular elements against the surface of the outermost sheet in the stack so that rotation of the circular element against the uppermost sheet in the stack will shingle that sheet from the stack.  Means are provided for abruptly stopping the rotation of the shaft whereby the follower and its supported element will then move back along the shaft out of engagement with the sheet surface.  At this point the sheet may be removed, after which the circular elements are again driven into engagement with the next uppermost sheet to shingle the same.

Abstract: A process for scavenging hydrogen sulfide from hydrocarbon gases utilizes iron oxide particles of unique chemical and physical properties. These particles have large surface area, and are comprised substantially of amorphous Fe2O3 containing a crystalline phase of Fe2O3, Fe3O4 and combina-tions thereof.  In scavenging hydrogen sulfide, the iron oxide particles are suspended in a liquid which enters into intimate mixing contact with hydro-carbon gases; the hydrogen sulfide is reacted at an exceptional rate and only acid-stable reaction products are formed.  Thereafter, the sweetened hydro-carbon gases are collected.

Abstract: ABSTRACT OF DISCLOSURE        The invention is concerned with a process for producing aqueous emulsions for air drying and stoving paints, on the basis of polyethyleneglycol modified alkyd resins, with improved stability over long periods.  In this process, fatty acid esters carrying ether-like bound polyethylene glycol radicals are reacted with normal alkyd resin raw materials to give an alkyd resin intermediate, which, in a next step, is esterified with an acidic vinyl copolymer carrying methacrylic acid and oil fatty acid radicals.  The excellent stability characteristics of the products despite the relatively low content of polyglycol of from 3 to 8 %, is due to the substantially unsaponifiable linking of the stabilising groups.

Abstract: ABSTRACT OF THE DISCLOSURE   A digital resolver processor measures the angle of a rotatable device.  A resolver connected to the rotatable device generates sinu-soidal signals as a function of an excitation signal and of the resolver angle.  A phase shift network receives the sinusoidal signals and generates leading and lagging phase shifted signals with a relative phase shift proportional to resolver angle.  A counter is enabled by the leading signal and inhibited by the lagging signal so that the contents of the counter represents the relative phase shift, and thus, the angle of the rotatable device.  The angular position of the resolver is limited so that the contents of the counter is maintained within a predetermined range in the absence of a fault condition of the resolver terminals.  The contents of the counter is forced outside the predeter-mined range in response to short or open circuit conditions of the resolver terminals, so that misleading angle representations may be recognized as such.

Abstract: ABSTRACT:         The invention relates to the serial transmission of binary data via an information channel and relates in particular to a method of coding and decoding predetermined binary block codes. The invention particularly relates to cases in which the information channel is in the form of an optical disc. In a block coding method, blocks of, for example, m data bits are converted to blocks of n channel bits (n > m). The blocks of information bits thus obtained must satisfy, for example, the requirement of being (d, k)-constrained. In (d, k)-constrained sequences the run length of "zeroes" is limited form a minimum d to a maxi-mum k of zeroes between each pair of consecutive "ones".         This coding has the disadvantage that it has a low-fre-quency spectrum which is too great to be ignored. Accord-ing to the invention, a block of separation bits is included between each of the blocks of n-information bits. In those cases where the format is not prescribed by the (d, k)-constraint the separation bits are chosen such that the low-frequency spectrum and particularly the direct current unbalance is as low as possible.

The accumulator plate is 5 millimeters or less in thickness, and is made of an aluminum alloy which, at that thickness, provides an isothermic plate which promotes uniform heat transfer and which has a coefficient of expansion which results in distortion of the surface plane of the plate to provide increased surface exposure, particularly during the early hours of the collection day, when the sun's rays are at less than a 90 degree angle.
