Title: Rapid acting countercurrent expulsion system
Inventor: ADAMS LOWELL J
IPC: B64D15/16
Filed: 1989-10-10
Abstract: ABSTRACT An electroexpulsive separation apparatus suitable for deicing of the leading edges of aircraft includes a pair of sheet-like arrays each containing in spaced-apart relationship a plurality of parallel ribbon-shaped electrically conductive members.  The electrically conductive members are electrically interconnected such that any electrical current flowing in the conductive members flows in the same direction in adjacent electrically conductive members in the first sheet like member and also flows in adjacent electrically conductive members of the second sheet-like array in a direction opposite.  The first and second sheet-like arrays are coextensive and superposed proximate to each other such that the electrically conductive members of the first and second sheet-like members are substantially parallel.  The electrically conductive members are electrically insulated from one another.  Large current pulses of predetermined magnitude, shape and duration are fed to the conductors from a power storage unit resulting in rapid and forceful separation of the first and second sheet-like arrays and other members associated therewith.  The separation force for a given conductor, physical arrangement and current pulse is much greater than that of prior known devices. 8254e

Title: Family of high affinity antibodies for cancer treatment
Inventor: MEZES PETER
IPC: A61K47/48
Filed: 1989-10-18
Abstract: This invention concerns a family of chimeric antibodies with high affinities to a high molecular weight, tumor-associated sialylated glycoprotein antigen (TAG72) of human origin.  These antibodies have (1) high affinity animal V H and V L sequences which mediate TAG-72 binding and (2) human C H and C L regions.  They are thought to produce significantly fewer side-effects when administered to human patients by virtue of their human C H and C L antibody domains. The nucleotide and amino acid sequences of V H.alpha.TAG V H, CC46 V H, CC49H, CC83 V H, and CC92 V H, and CC49L, CC83 V L, and CC92 V L idiotype sequences are disclosed, as well as in vivo methods of treatment and diagnostic assay using these chimeric antibodies.

Filed: 1989-11-17
Abstract: ABSTRACT OF THE DISCLOSURE           The invention relates to a process for producing gas mixtures by  a plurality of dilution steps of a high concentration standard gas with a high purity diluent gas.  According to the invention, as soon as the high purity diluent gas is generated, no further contaminants such as gaseous impurities are added during the further mixing or diluting steps of the process.   Only orifices or needle valves are used in the mixing  or  diluting  lines while mass  flow controllers  and pressure regulators are placed upstream, at the output of  the gas sources and/or downstream, i.e. in the gas  venting  lines.  The invention particularly applies to trace analysis of gases with APIMS.

Abstract: Abstract of the Disclosure:         In an encoder device for encoding a sequence of digital speech signals classified into a voiced sound and an unvoiced sound into a sequence of output signals, by the use of a spectrum parameter and pitch parameters, at every frame having N samples where N represents an integer, a judging circuit judges whether the digital speech signals are classified into the voiced sound or the unvoiced sound to produce a judged signal representative of a result of judging.  A processing unit processes the digital speech signals in accordance with the judged signal to selectively produce a first set of primary sound source signals and a secondary sound source signals.  The first set of primary sound source signals are produced when the judged signal represents the voiced sound and are representative of locations and amplitudes of a first set of excitation multipulses calculated at every frame.  The second set of secondary sound source signals are produced when the judged signal represents the unvoiced sound and are representative of the amplitudes of a second set of excitation multipulses each of which is located at intervals of a preselected number of the samples.

Title: Chromium-free impregnated activated carbon for adsorption of toxic gases and/or vapors
Inventor: DOUGHTY DAVID T
IPC: B01D53/02
Filed: 1990-06-26
Abstract: Impregnated activated carbon adsorbents for the removal of toxic materials from gas streams are used in a variety of respiration and collective filter applications.      The activated carbon impregnated adsorbents in the present invention remain effective in removing toxic gases and/or vapors in military, industrial and other applications, and are free of chromium and its potential health hazards.      Generally, these activated carbons are comprised of an activated carbon adsorbent impregnated so as to result in an activated carbon containing 0 to 14% copper and 2 to 16% zinc, optionally supplemented according to the desired characteristics with silver, triethylenediamine, and molybdenum, prepared pith or without the use of organic acid. The adsorbent carbons of the present invention have been found to be effective for removing a variety of toxic gases and/ or vapors, The formulation of the impregnates, the method of impregnation and the method of drying the activated carbon after impregnation taught by the present invention can be varied to adjust the performance characteristics so as to meet both industrial and military toxic gas performance criteria, to achieve enhanced removal of specific toxic gases and/or vapors, to have an extended shelf life, as well as to obtain other advantages useful in respirator and collective filter applications. The impregnated carbon adsorbents in the present invention possess desirable qualities regarding the toxicity and carcinogenicity of the impregnates to the user, qualities that are not found in a large number of prior art impregnates potentially useful in respirator and collective filter applications.

Title: Safety device for a sanitary fitting
Inventor: HOCHSTRASSER FERDINAND
IPC: E03C1/10
Filed: 1990-08-02
Abstract: ABSTRACT OF THE DISCLOSURE    A sanitary fitting which has a safety device for preventing water from flowing back into the supply line.  The valve body  is rigidly connected to the actuating body through which the water flows.  Under normal operating conditions, in which the actuating body is under pressure by the water in the direction of flow, the sealing lip bears against the valve seat.   The closed valve separates the flow path from a venting path.   Under backflow conditions,  the  actuating  body  is  pressured  counter  to  the direction of flow, which causes it to be moved counter to the direction of flow and the simultaneous compulsory opening of the valve.  The supply line of the fitting is thus connected to the surrounding air by venting path.

The adhesion of the first heat adherent resin layer is increased by the primer layer.  Therefore, the first heat adherent resin layer is adhered strongly to the base material or the suppression.    When peeled off the base material, the base material, the primer layer and the first heat adherent resin layer are peeled off from the postcard material in the postcard material  including  the  base  material  having  the suppressiveness, while, the base material, the suppression layer, the primer layer and the first heat adherent resin layer are peeled off from the postcard material in the postcard material including the suppression layer having the suppressivess.  Therefore, the surface of the postcard can be seeing.    According to the present invention, an postcard which is able to cover preferably and temporarily an information matter of the surface of the postcard material without any process on the surface of the postcard material,  and a manufacturing method thereof are obtained.
