Title: Distributed-array radar system comprising an array of interconnected elementary satellites
Inventor: GALATI GASPARE
IPC: G01S7/00
Filed: 1988-03-25
Granted: 1993-03-16
Abstract: ABSTRACT OF THE DISCLOSURE        A radar system for primary and secondary airspace surveillance, and especially for the detection and tracking of moving targets, consisting of a number of elementary satellites connected to nonrigid structures and of a main satellite, which performs accurate measurement of the position and altitude of elementary satellites and real-time adaptive combination of radar signals coming from them, so as to provide a large-phased array operating in the microwave band.  This system overcomes the limitations on dimensioned large space-bound antennae found in the literature, minimizing the incidence and effects of undesired echoes and interference and assuring high detection accuracy.  The fact that the elementary satellites are all the same (modular) makes possible gradual assembly of the system with possible expansion in time and assures particularly high operating availability.   ef-PC

Title: Method of selective reduction of polyhalosilanes with alkytin hydrides
Inventor: SHARP KENNETH G
IPC: C01B33/107

Granted: 1992-11-24
Abstract: METHOD OF SELECTIVE REDUCTION OF POLYHALOSILANES WITH ALKYLTIN HYDRIDES                           ABSTRACT           The invention relates to the selective and stepwise reduction of polyhalosilanes by reacting at room temperature or below with alkyltin hydrides without the use of free radical intermediates.  Alkyltin hydrides selectively and stepwise reduce the Si-Br, Si-Cl, or Si-I bonds while leaving intact any Si-F bonds.  When two or more different halogens are present on the polyhalosilane, the halogen with the highest atomic weight is preferentially reduced.

Title: Ear wax barrier for a hearing aid
Inventor: WEISS ERWIN M
IPC: H04R25/00
Filed: 1988-04-12
Granted: 1992-02-18
Abstract: ABSTRACT         An ear wax barrier for a hearing aid to prevent ear wax from contacting and damaging the internal components of a hearing aid or hearing aid receiver.  The barrier includes a housing defining a central axis of passage, as well as a plurality of projections and a variable acoustic attenuator.  The projections extend inwardly from the interior surface of the housing, each projection partially occluding the cross-sectional area of the housing.  The projection provides a tortuous path for ear wax migrating into the hearing aid.  The variable acoustic attenuator and the projections provide a constricted passageway for damping of the acoustic response of the hearing aid.

Title: Package wrapping method and machine
Inventor: TREIBER FRITZ F
IPC: B65B11/20
Filed: 1988-08-17
Granted: 1992-02-18
Abstract: PACKAGE WRAPPING METHOD AND MACHINE               Abstract of the Disclosure An elevator package wrapping machine comprises a film gripper for initially drawing fixed lengths of film into the machine.  While the film is held by the film gripper and side clamps, a package is elevated into the film such that the height of the package draws a first addition to the film drawn by the gripper, if required.  Film side and rear underfolders fold the lateral edges of the film and the rear edge of the film extending from the film source under the packages, respectively.  A film cutter is provided for severing the film from its source as the packages are being wrapped, and the cutter is controlled such that the timing of its operation is based on package length.  By timing the operation of the film cutter to correspond to package length, a second film addition may be drawn by the rear underfolder during package wrapping, if required.  Since the film may be cut on the fly as it is being drawn by the rear underfolder, the cutter preferably comprises a heated member and a brake which is applied to the film prior to severance such that the film is substantially stopped and stretched to thereby be cleanly severed and retract from the heated member to prevent fouling.

Abstract: ABSTRACT           A needle assembly is disclosed which comprises a hub to which a needle is fixed.  A spring is coupled to the hub and surrounds the needle.  The free end of the spring retains an end cap which is intended to cover the tip of the needle after use of the needle assembly.  A clamp may be used to maintain the spring compressed so that the needle assembly can be used and after use the clamp is removed so that the needle biases the end cap into a position where it covers the end of the needle.  Alternatively, a deformable cylinder may be coupled with the hub and have clip members which engage corresponding clip recess on the end cap to maintain the spring compressed.  Upon deformation of the deformable member the end cap is released from the deformable member so that the spring biases the end cap into a position encapsulating the end of the needle.
