Abstract: ABSTRACT OF THE DISCLOSURE         Rectangular base mounting-platform structures for removable combat-equipment, for example, guns and other support units like radar which are mounted on rectangular openings on a ship deck, are provided with interchange-ability.  In order to achieve interchangeability of units which have mounting-platform structures of unequal size, the platform rectangular dimensions as well as the dimensions of the corresponding rectangular openings are so designed that the base length of the smallest unit is made equal to the width of the next bigger rectangle and so forth; in order to mount the smallest rectangular base on the immediate next larger rectangular opening, the length of the smallest rectangular base is aligned with the width of the larger opening; mounting is so done as to leave an open space towards only one side, leaving only one longer side of the smallest rectangular base unsupported within the area of the mounting opening.  The unsupported side is supported by a beam running under the mounting opening, which beam transfers the load to other structure which reinforces the rectangular opening.  An area of the rectangular opening which is thus left uncovered is covered by a suitable covering member.  The mounting of the rectangular base structure, and the covering member, as well as the ends of the beam, are provided with sealing members to render the platform-structure impervious.  Three consecutive rectangular sizes are preferred wherein the width of a rectangle is the same as the length of the immediate smaller rectangle.

Abstract: D-23,099C     SWITCH MODE - CLASS B POWER AMPLIFIER                                By Edward T. Ball and John E.R. White Abstract of Disclosure An input signal is applied to the inverting input of a class B amplifier and to the input of a limiter circuit.  The square wave signal from the limiter is applied to the input of a switching amplifier which drives this amplifier between V and ground at the switching rate established by the input signal; thereby, obtaining a power control signal.  The power control signal is applied to one terminal of a load and to the non-inverting input of said class B amplifier.  Ignoring the input signal to the amplifier, this switches the output of the class B amplifier between V and ground at the same rate and in phase with the output from the switching amplifier.  m e gain of the input signal path in the amplifier is such that the input signal will just drive the output between V and ground.  The switching action of the power control signal in combination with the input signal then causes the output signal across the load to have the same characteristic as the input signal but with a peak-to-peak amplitude of 2V.

Abstract: ABSTRACT OF THE DISCLOSURE           The invention relates to a programmable signal pro-cessing device primarily intended for hearing aids and of the kind which include an electronically controlled signal pro-cessor.  Hearing aids for persons having impaired hearing are normally adjusted for only one frequency response and are adapted to amplify the frequencies which the patient has difficulty in hearing.  At different sound environments, as for example conversations with disturbing background sounds, normal conversation in quiet environments or at lectures, the conditions of listening are different.  Up to now this pro-blem has not been solved satisfactorily for hearing aids. With the present invention a number of different signal pro-cesses, can easily be selected to suit different sound situa-tions automatically or by the user himself.  This is accompli-shed in that a memory is arranged to store information/data for at least two unique signal processes adjusted to different sound environments/listening situations and that a control unit, manual or automatic, is arranged to transmit information/ data, for one of the unique signal processes, from the memory to the signal processor, to bring about one signal process adjusted to a particular sound environment/listening situa-tion.

Abstract: MULTILAYER FILM MANUFACTURE UTILIZING SCRAP RESIN                 ABSTRACT OF THE DISCLOSURE          A novel system for producing film by extruding and/or casting at least two layers of resin, such as polyacrylonitrile homopolymer or interpolymers.  The system provides for co-extruding a continuous multi layer film with contiguous or tandem dies from a first supply of homogeneous resin solution and a second supply of non-homogeneous redissolved resin scrap.  The film may be cast onto a smooth cooled drum surface to form substantially continuous adjacent layers from two or more resin supplies.  By stripping the film from the drum as a continuous film strip and stretching the film an oriented structure is provided.  Scrap resin, such as selvage trimmed from the stretched film or mill scrap, is comminuted and redissolved in solvent for recycle to the second supply of the extrusion step.  The homogeneous layer prevents film disruption by inhomogeneities present in the contiguous layer containing redissolved scrap, which might cause localized stresses in the film and discontinuities during stretching.
