Title: Reclaimer ameliorator polymeric gel
Inventor: AZZAM REDA A I
IPC: C05G3/00
Filed: 1992-02-28
Abstract: RECLAIMER AMELIORATOR   POLYMERIC GEL      INVENTOR: DR. REDA ALY IBRAHIM AZZAM            ABSTRACT   Gelatinous polymer of hydrocarbon and carbohydrate is prepared by ionizing radiation from acrylonitrile derivatives and agricultural discard for instance rice straw and others after being treated chemically. The product induces aggregation of sandy dune particles. It absorbs about 300 times its weight water. It raises also the cationic exchange capacity of soils and buildup the fertility chemically and biologically in cultivated land. The product increases the agricultural productivity two and half folds when applied to the soil at a rate equivalent to 50 Kg. per feddan.   The product is merely a polymer of multi-units composed of carbonic chain having an average length of 7 million carbon atom in connection at least with amide, carboxylic and hydroxide groups. RAPG is composed of two principle ingredients. These are hydrocarbon and carbohydrate. The hydrocarbon is represented by a primary petro chemical product. This is prepared by reacting propylene gas which is a secondary product of petroleum refinery process with ammonia gas in presence of air. So, acrylonitrile is produced:          CH2:CHCH3 + NH3 + 1? O2 - CH2:CHCN + 3 H2O Acrylonitrile abstracts one water molecule in presence of a catalyst, as for example sulphuric acid or others, forming acrylamide:         CH2:CHCN + H2O - CH2:CHCONH2 The latter hydrolyses in alkaline media, for example, sodium hydroxide forming acrylic acid:          CH2:CHCONH2 + H2O - CH2:CHCOOH + NH3 On the other hand, the carbohydrate is represented by cellulose, starch and their principle source in this invention the agricultural discard, for example, rice straw, barley and wheat. These are all polymers of multi-succarides, hydrolyse to mono-succaride.   The herein above compounds hydrolyse in aqueous mixture solution on irradiation by ionizing radiation to radicals. These bind together instantaneously forming long carbon chain having the distinct functional groups related to each compound. The optimum radiation dose for radiolysis and polymerization varies between 2 KGy and 100 KGy.   The architecture of the polymer depends on type and concentration of the ingredients, pH, temperature of the medium and percentage of atmospheric air, specially the oxygen. The integral dose and dose rate affect directly the polymer properties. The post-effect and temperature of the medium have synergistic effect on polymeric stereo-configuration, yet its extent dependent on the type and state of the ambient medium. These factors have been optimized for preparing the reclaimer-ameliorator polymeric gel. This resulted in achieving its peculiar properties of conditioning sand dunes for plantation and reducing water losses in deserts by percolation and evaporation, as well as amending arable land via increasing its chemical and bacteriological fertilities.

Title: Method of transport and distribution of helium by means of mobile bulk storage tanks
Inventor: BRUZZI STEFANO
IPC: B01D5/00
Filed: 1992-06-05
Abstract: Summary Helium is transported and distributed in mobile bulk storage tanks (1) and filled at filling stations (3) into smaller consumer tanks (11).  The contents of the tank takes up heat continuously from the surroundings, which leads to a contin-uous rise in temperature and pressure of the contents of the tank, so that the original liquid helium above a critical pressure turns into a singlephase supercritical fluid.  The bulk storage tank (5) may at need be brought to a recooling station (2) which by a recooler group (4) which exhibits a closed cooling circuit cools a heat-exchanger (29) which cools the contents of the bulk storage tank (5).  Through the extraction of heat the contents of the bulk storage tank (5) may be cooled as often as desired to a usually standardized temperature.     (Figure 1)

Title: Flexible-multiplexing process and device
Inventor: EHRICKE CLAUS
IPC: H04J3/22
Filed: 1991-02-28
Abstract: Abstract A  flexible  multiplexer  for  speech,  data  and signaling information signals having an individual n-fold bit rate (n = 1, 2, 3, ...) at the external inputs and outputs is to be assigned further interface units (7b, 7c, 8b, 8c) without changes to the basic device (I). This is made possible by add-on switching matrixes (16b, 17b) in which speech/data and signaling information signals (S/D-ES1, Kz-ES1) combined in interface units (7a, 8a, 12, 13) of the basic device (I) to form multiplex signals (S/D-EM1, Kz-EM1), and speech/data and signaling informa-tion signals (S/D-ES2, Kz-ES2) combined in the further interface units  (7b,  7c,  8b,  8c)  to  form multiplex signals  (S/D-EM2,  Kz-EM2)  are cross-connected and are output  as  new  multiplex  signals  (S/D-AM1,  S/D-AM2, Kz-AM1, Kz-AM2) both at interface units (7a, 8a, 12, 13) of the basic device  (I)  and at the further interface units (7b, 7c, 8b, 8c). If a plurality of bytes originat-ing from one frame were to end up temporally in two different  frames  during  cross-connection,  then  time compensation can be accomplished with a delay of the duration of one frame via bus loops  (33,  34)  between outputs and inputs of the add-on switching matrixes (16b, 17b). Flexible multiplexers permit a liberal grouping and distribution of time slots of digital multiplex signals.            Figure 4

Title: Power down miller killer circuit
Inventor: OHANNES JAMES R
IPC: H03K19/017
Filed: 1992-12-04
Abstract: POWER DOWN MILLER KILLER CIRCUIT ABSTRACT   A circuit to be used with bistate and tristate output buffers as a means of diverting from an output pulldown transistor the Miller Current arising while the output buffer is powered down. Its purpose is to avoid loading the common bus to which the output buffer is attached, in particular under the circumstances where other output buffers on the bus are causing transitions to occur and the buffer of interest has been powered down. In its preferred embodiment the invention utilizes a CMOS transistor, PDMK transistor (Q99), coupled between the output pulldown transistor and the low-potential power rail of the output buffer. The PDMK transistor (Q99) is controlled by a PDMK driver transistor (Q99A) coupled to the buffer output VOUT. The PDMK driver transistor (Q99A) is controlled by the output buffer's high-potential power rail and so turns on the PDMK transistor (Q99) only when the buffer is powered down. The invention also encompasses a PDMK disabler transistor (Q98) coupled to the data input VIN to ensure that the PDMK transistor (Q99) never pulls the control node of the output pulldown transistor when the buffer is in its active low state.

Abstract: ABSTRACT OF THE DISCLOSURE      A linear actuator has reversible electric motors driving a screw-threaded shaft engaging a roller nut.  A tubular housing attached to the nut has at its remote end an internal seating and load securing lugs.  An hydraulic shock absorber unit, giving linear deceleration, is normally held in its most relaxed condition between the seating and an end of a spacer tube butting against the nut. When the nut is within the shock absorber stroke distance of the driven end of the shaft, the free end of the shaft compresses the shock absorber unit against the seating.  When the nut is within shock absorber stroke distance of the free end of the shaft, a ring engages a stop collar, thereby holding the shock absorber body at a fixed distance from the free end of the shaft, and the spacer tube compresses the shock absorber unit.  A centrifugal brake is provided on a drive coupling pulley, and restrains rotation of the shaft above a predetermined rate.

A second spiral spring cooperates with the first mentioned spring to locate the barrier in an operatively disposed position forward of the vehicle and permits momentary displacement of the barrier.  A pair of switches serve to establish polarity reversing motor circuits with the switches in relay controlled circuits with a driver actuated vehicle door control switch.  A barrier mounted light is in circuit with the vehicle's amber light system.
