Abstract: ABSTRACT OF THE DISCLOSURE            Aerosol particles, resulting from the combustion of organic substances with insufficient oxygen supply, usually contain toxic, higher hydrocarbonic substances (e.g. tar) on their sur-face. These substances, e.g. tar, has the property to be photo-electrically more active than other substances contained in the athmosphere. In the apparatus according to the invention the aerosol to be characterized is fed through a chamber and sub-jected to ultraviolet radiation. A controllable fan provides a desired flow velocity of the aerosol, contained in a carrier gas, through the chamber. Thereafter the charge of the photo-electrically positively charged particles is determined by means of size-selective filter means which are connected to current or charge measuring equipment. The measured values are proportional to the amount of tar present on the surface of the particles contained in the aerosol. The apparatus is particu-larly useful for the measurement of air pollution.

Abstract: POWERED BACK-UP TONGS, ABSTRACT     A powered back-up assembly is provided for securing a pipe against rotation.  A plurality of heads are supported by a cage plate assembly, and are brought into gripping engagement with the pipe by rotating the cage plate assembly relative to a cam ring fixed to the body of the tong body.  The cage plate assembly is rotated by a pair of hydraulic cylinders each connected at one end to a bar pivotably connected to the tong body.  A third hydraulic cylinder interconnected between adjacent upper and lower tong bodies may be employed to achieve a reliable scissors tong, whereby the body of the upper tong is rotatable relative to the body of the lower tong.

Abstract: ABSTRACT:              A method of manufacturing a semiconductor device having narrow coplanar silicon electrodes which are separated from each other by grooves or slots having a width in the submicron range.  The electrodes are alter-nately covered by oxide and by an oxidation-preventing layer, for example silicon nitride.  According to the in-vention, a first and a second electrode, which are covered with the same layer and which enclose a third electrode covered by the other layer are first interconnected inside a connection region.  Two of the three electrodes are separated from the connection region by etching.  By selective etching, overlapping contact windows are pro-vided on all three electrodes.

Abstract: PREDICTIVE COMMUNICATION SYSTEM      FILTERING ARRANGEMENT     Abstract A digital communication system includes a predictive decoder that is operative to convert received digital codes into a predictively decoded signal, e.g., speech signal, and to generate a set of predictive parameter signals and a signal representative of the communication system bit rate.  A set of filter control signals is generated responsive to the communication bit rate signal.  The predictively decoded signal is passed through a filter which modifies the output signal responsive to the filter control signals and the decoder predictive parameter signals to improve the output signal quality.  The filter control signals selectively alter the predictive parameter signals to optimize the predictively decoded signal modification for the current transmission bit rate.

Abstract: Abstract of the Disclosure A sealing arrangement for an air preheater for a fuel burning device includes both radial and circumferential seals.          The radial seals include a set of flexible, foil-like metal sealing strips coupled to semi-rigid radial seal plates.  The semi-rigid radial seal plates, in turn, are coupled to diaphragm members which divide a generally cylindrical drum of the air preheater into sectors, each sector containing a set of heat exchanger elements, such as parallel plates or fins.  To effect sealing, the foil-like metal radial sealing strips will engage and wipe across sector plates on a housing surrounding the drum The radial sealing strips are completely unobstructed from can-tilevered yielding movement in a trailing direction to the full extent that the flexure characteristics of the radial sealing strips themselves permit.  The circumferential sealing strips are also constructed of a flexible, thin, foil-like metal material.          These circumferential strips are coupled to circumferential seal plates which, in turn, are connected to the drum of the air pre-heater adjacent the outer circumferential edges of the drum.  The circumferential sealing strips yieldingly engage annular surfaces of the housing surrounding the drum to effect sealing between the drum and the housing.  Each circumferential sealing strip in-cludes a sharp bend adjacent its free distal edge to direct the free distal edge toward engagement with an annular sealing sur-face of the housing.

Abstract: ABSTRACT    A glass cutter having an internal lubricant supply comprises few parts, and yet provides the fluid to the cutting element in a neat and highly effective manner.  When not in use, the internal reservoir is sealed against the entry of air and flow of oil therefrom is thereby prevented.  Force upon the cutting head will displace it rearwardly into the handle, thereby opening a valve by shifting an interconnecting tubular stem, admitting air into the reservoir.   The air passes through the stem, the lubricant flows along its exterior, and both pass through a wick disposed to apply the lubricating fluid to the cutting wheel.

Abstract: ABSTRACT          "Synthesis Gas"         Carbon dioxide is removed from a raw gas containing hydrogen, carbon dioxide, and intermediate boiling gas, eg nitrogen, to give a gas suitable for use as a synthesis gas by a wet carbon dioxide removal process, and the resultant carbon dioxide depleted gas is subjected to pressure swing adsorption (PSA) to remove some, or all, of the intermediate boiling gas and the bulk of any residual carbon dioxide. The PSA waste gas is used to strip the absorbent liquid in the regeneration of the latter in the wet carbon dioxide removal process.  The process is of particular utility in the manufacture of ammonia synthesis gas from a raw gas containing an excess of nitrogen, particularly as prepared by primary/secondary reforming/shift of a carbonaceous feedstock with partial bypass of the primary reforming stage.

Abstract: ABSTRACT OF THE DISCLOSURE         It is possible with this apparatus to prevent major loss of time, especially during periods of high traffic density in the downward direction, in that only one elevator-cabin of a group of elevator-cabins, adapted to carry a suitable load, is used to serve a specific floor, thus second stops to serve remaining passengers being eliminated.  To this end, an adding device is provided to establish a total of the number of passengers in the elevator-cabin and the number of passengers waiting at the next floor to be served.  This total is compared, in a comparator, with a maximal permissible number of passengers corresponding to a limit-load-value.   If the said limit-load-value is exceeded, the elevator-cabin does not stop at the floor and the unserved call is allocated to another elevator-cabin.  If the said sum is equal to, or less than, the said limit-load-value, the elevator-cabin stops at the relevant floor.

Abstract: HYDRODYNAMIC LUBRICANT SEAL FOR DRILL BITS            ABSTRACT OF THE DISCLOSURE           A hydrodynamic lubricant sealing element for devices such as rotary cone rock bits, shaft seals and the like which is maintained under sufficient mechanical compression to effect a seal between relatively movable structures.  The sealing element defines a sealing surface establishing a seal interface with a relatively movable circular sealing surface and forms a lubricant interface and a contaminant interface at opposite sides thereof.  The lubricant interface is of such configuration as to induce a hydrodynamic lubricant wedging activity causing migration of lubricant film in the seal interface from the lubricant interface to the contaminant interface for flushing away any contaminant and for lubrication between the sealing element and sealing surface.   The contaminant is of a configuration developing substantially no such hydrodynamic wedging activity at the contaminant interface and yet presenting a scraping edge to remove contaminant material from the sealing surface upon relative axial movement of the sealing surface and sealing element.
