Abstract: ABSTRACT OF THE DISCLOSURE         The vibratable diaphragm of an electret transducer has in its central plate portion one or more formed ribs, ridges or projections resting on a substantially flat backplate.  These support the active regions of the diaphragm with precise spacing from the backplate.  Elongate projections can be formed to relieve membrane stresses in the diaphragm.  The flexural stiff-ness of the diaphragm is sufficient in itself to provide mechan-ical stability of the diaphragm in the presence of the destabil-izing forces of electrostatic attraction by the backplate.

Abstract: ABSTRACT OF THE DISCLOSURE      A platen press has upper and lower platens each provided with at least one rigidifying beam.  A group of hydraulic cylinders spaced about over one of the platens serves to urge the two platens together in a pressing direction to compress a workpiece--plywood, fiber mat, chipboard, or the like--between the platens.  During pressing the platens and their rigidifying beams bend somewhat.  This bending is measured by an apparatus which comprises a flexible strand, holders at the end of the one beam for gripping the ends of the strand and holding same straight and under tension, and sensors fixed on the one beam at a location between the ends of the one beam for measuring the displacement of the strand relative to the beam at the location during pressing.  This sensor lies wholly out of physical contact with the strand

Abstract: ABSTRACT OF THE DISCLOSURE         For storing heat-releasing radionuclide configurations, particularly burned-out fuel elements, with free cooling with ambient air,apparatuses are required which visually comprise a housing provided with charging passage, supply-air and spent-air ducts and closed storage cells which contain storage racks, which contain horizontally arranged or inclined storage shafts to receive the radionuclide configurations.  These apparatuses are intended to assure a reliable emission of heat with a supply of cooling air as optimal as possible and to protect the ambient air against direct irradiation.  For this purpose the ceilings of the storage cells have been designed as heat exchangers and within the storage cells at the storage shaft orifices there are disposed functionally separated up-draft chimneys and down-draft chimneys.

Abstract: NOVEL PROSTAGLANDIN ANALOGUES AND PROCESS        FOR MAKING SAME Edward David Mihelich Abstract A novel process for the oxidation of olefins to the corresponding alpha-epoxy alcohols which can be incorporated in the total synthesis of members of a novel class of prostaglandin analogues. Olefins are reacted with singlet oxygen in the presence of a group IVB, VB or VIB transition metal catalyst, excluding chromium. The reaction is fast and highly selective to the alpha-epoxy alcohol. When cyclopentene is oxidized in the process of the invention, high yields of cis 2,3-epoxy-cyclopentan-l-ol are obtained. The latter compound is used as a starting material in the synthesis of prostaglandin analogues. The prostanoids of the invention are characterized by an oxa group replacing the methylene group at the 7-position, and the absence of a hydroxyl or other substituent at the 11-position. Members of this class of prostanoids show important cytoprotective properties in animal tests.

Abstract: ABSTRACT:       The invention relates to an amplifier comprising means for eliminating direct-voltage transients on the amplifier output. For this purpose there is provided a controllable voltage source, which is coupled to the out-put or to a point in the amplifier in such a way that the output voltage gradually increases to the steady-state value.  The magnitude of the output voltage of said source, which conducts current in one direction only, can be con-trolled by means of a control voltage which is continu-ously variable during the turn-on period and which is applied to its input.  The voltage source is connected to the amplifier in such a way that, as the amplifier output voltage rises, it is cut off by the resulting potential changes.

Abstract: ABSTRACT OF THE DISCLOSURE       An improvement is disclosed in a method for the separation of hydrogen and/or dueterium and tritium from an inert gas flow which is contaminated with one or more of these elements.  In which the inert gas which is to be purified is conveyed along the primary side of an exchange wall for hydrogen isotopes.  The improvement resides in adding an agent on the secondary side of the exchange wall which chemically reacts with the permeating hydrogen isotopes so as to bond the hydrogen isotope or isotopes which are to be separated out of the inert gas flow being purified into a reaction product transportable in a gas flow which is not permeable through said exchange wall. A carrier gas is conveyed along the secondary side of the exchange wall in orderto carry off the reaction product.  Additionally disclosed is an apparatus especially adapted for the carrying out of this method.

Abstract: ABSTRACT     IMPROVEMENTS IN ABLUTIONARY SHOWER SYSTEMS     An automatic drain-off valve for an ablutionary shower system is provided at the lowest point of the supply pipe at or from the shower control or mixing valve to the shower spray head.  The drain valve (30) comprises a body (1) having a chamber (7) in which a clack valve (3) is mounted and which is normally biassed into the open position relative to a port (16) surrounded by a seating (8).  The port (16) comprises a series of through bores opening to the bottom of the valve for discharging water from the chamber (7) to waste.  When water flows through the supply pipe of the shower system, the chamber (7) fills and pressure on the clack valve overcomes the bias applied to the valve spindle (4) by a spring (14) so that the valve close on the seating (8).  A clearance gap (9) is provided between the periphery of the clack valve and the internal wall of the chamber (7) to ensure that when the valve is open water can drain through the valve, but the gap is small and restricts flow when the chamber (7) is filled and cause pressure build-up in the chamber (7) to close the valve.  In a modification, the spring bias is adjustable.  Automatic drain-off in shower systems is considered as a preventative measure with regard to Legionnaire's disease as well as for other advantages avoiding stagnation of water in the shower head supply pipe.  Various installations are described.
