Abstract: Serial No. 257 742 Danfoss A/S (Brown, Alvin E.) APPARATUS FOR DETERMINING THE ARRIVAL, TIME  OF ALTERNATING SIGNALS     ABSTRACT OF THE DISCLOSURE         Received ultrasonic bursts of energy are rectified and converted into pulse trains and also envelope detected. The envelope is red to a ramp generator whose output is threshold detected to provide an arrival delay  signal corresponding in time to the peek amplitude of the received bursts.  A regulator circuit varies the timing of the arrival delay signal to coincide with the next negative-going zero crossover of the pulse train,  A timing generator provides a reference delay offset, relative to the transmission time of the ultrasonic bursts, by the expected transit time there-of.  The timing of the reference signal is varied in the same manner as the arrival delay signal by the regulator circuit and compared with the positive-going zero-crossover in the pulse train next following the negative-going zero-crossover. Thus determined accurately the actual time of arrival of the bursts, using  low cost components.

Abstract: ABSTRACT OF THE DISCLOSURE           A roofing system and construction wherein a water proof membrane con-sisting of an impervious base sheet being applied directly to the surface of a roof deck.  The waterproof membrane is a heavy duty material having a high strength heat resistant mesh throughout and integral in the membrane.  This base sheet membrane has a bottom surface of self-adhesive rubberized material and, upon application of the base sheet membrane to the roof deck, results in a permanent bond between the roof deck and the base sheet membrane.  An insulation layer of sprayed insula-ting foam is applied directly to the top of the base sheet membrane and the chemical composition of the spray foam and the chemical composition of the base sheet upper surface further provides for a permanent and continuing bond therebetween upon the application of said insulating foam.      The foam thickness is determined by the specified installation demands for the roof system design.  The foam spray insulation provides a substantially seamless insulating layer throughout the roof system.      The top surface of the insulating foam has thereupon applied a weather protective coating and seal such as a hydrocide elastomer, which elastomer is sprayed or brushed on to form a continuous and seamless coating exposed to and protecting the roof system from the weather and external conditions.      The present invention permits application of the base sheet mem-brane about cut-through stacks and projections of a rood simultaneously with the installation of the roof system in a manner providing a complete water and weather seal about said cut-through and projections in a roof system.      The method of application for this roof system at a roof edge results in a seal of the base sheet membrane and positioning of insulation spray foam material in place on a continuous base for the roof and provides an effec-tive seal after application of a rubberized or vinyl elastomer coating thereon.

Abstract: ABSTRACT OF THE DISCLOSURE    A hardened wear spot on a textile element is formed by applying high energy heat to a selected small area of the element which has been previously hardened and tempered to provide the proper spring characteristics for an operating textile element.  The intensity and time of application of the high energy heat and the cooling after heat cut-off are care-fully controlled to provide a small area of full hardness which is completely separated from the remaining tempered portion by a buffer zone of less hardness than either the tempered portion or the full hardness area.   The new textile element made by this new method is a textile element with the major portion having a predetermined spring characteristic for an operating textile element. A small area of full hardness is located at a predetermined location to provide wear resistance.  A buffer zone having less hardness than either the full hardness area or the major tempered portion completely separates the full hardness area from the major portion.

Title: Organosolv delignification and saccharification process for lignocellulosic plant materials
Inventor: PASZNER LASZLO
IPC: C07C51/00
Filed: 1977-08-31
Granted: 1981-05-05
Abstract: ABSTRACT OF THE DISCLOSURE     Hereby a novel process is described which is capable to take most any subdidvided, chipped, shredded, hammermilled lignocellulosic forest and/or agricultural residue, pure or in mixtures thereof, and with the aid of a chemical agent,which is essentially a mixture of an organic volatile solvent with water, such as ethanol or acetone, acidified with either an inorganic strong acid such as hydrochloric, sulphuric or phosphoric acid, or an organic acid such as oxalic, formic, citric, maleic, plicatic, tannic, tartaric, trichloroacetic or trifluoro-acetic acid, convert it into pulp, crystalline cellulose, dissolved chemicals such as sugars, lignins, furfurals and organic acids in high yield.  The process of conversion is continuous but can be subdivided-into stages according to the order of product formation.  The conditions under which these products are formed are very conducive to rapid hydrolysis and usually involve liquor pH at  4 and lower, a temperature of 160°C but not exceeding 210°C, and a pressure appropriate with these temperatures and the cooking liquor composition. Product composition is mainly influenced by cooking time at maximum specified temperature and liquor composition,i.e., more than one product mix can be produced with a single set of temperature/pressure and cooking  liquor composition by merely increasing or decreasing the exposure time at maximum temperature.  The equipment is so designed that it make possible the production and recovery of the whole range of chemicals (products) indicated above.  It is a further characteristic of the pro-cess that it treats most all lignocellulosics with nearly equal efficiency and thus such plant materials may also be processed in mixture without serious deterioration of product quality and process efficiency.  A high degree of cooking chemical recovery is possible and continuous re-covery is an integral and important part of the process.         Thus this invention does not limit itself to the solvent system by which such rapid production of high to low-yield pulps, bulk lignins and sugars and sugar dehyd-ration products are possible from all types of lignocellu-losics, neither is it limited to the conditions under which such flexibility is possible but is also concerned with the apparatus which would allow efficient, economic, orderly and controlled high yield manufacture of such a product mix as  outlined in Figure 1.

Abstract: TAPE MOTION CONTROL IN AN INCREMENTING    MAGNETIC TAPE TRANSPORT                     Abstract of the Disclosure In a rotating head magnetic tape transport, the tape is maintained stationary as the head sweeps a selected data track.  A length of tape is buffered in a vacuum column between a supply spool and the rotating head station.  A take-up spool on the opposite side of the head station is servo controlled to maintain proper head/track align-ment and to periodically step the tape to an adjacent track.  Changes in the tape radius on the take-up spool are compensated for by (1) a stop-lock source of motor energization whose magnitude is servo con-trolled by unbalance between the vacuum column force tending to pull the tape in one direction and the take-up spool motor torque tending to pull the tape in the opposite direction, and (2) a step modifica-tion network which responds to head/track alignment error caused by the variable tape radius on the take-up spool.
