Abstract: ABSTRACT        The present invention provides an X-ray tube which produces less external stray radiation than conventional tubes.  It includes the usual evacuated envelope, and an X-ray generating target located within the envelope.  An electron gun is positioned within the envelope to direct a stream of electrons at the target.  The X-rays generated at the target are passed through a window to a point of use beyond the envelope.  The major improvement of the present invention consists in providing a high density attenuator within the envelope which has an axial bore in line with the direction of the electron stream and has at least a substantial portion of its axial length extending into the space between the target and the electron gun. The configuration of the axial bore and its disposition as stated serves to attenuate the high energy photons which do not leave the envelope through the window.

Abstract: VOLTAGE BOOST CIRCUIT FOR     TELEPHONE SYSTEMS     Abstract of the Disclosure In a voltage boost circuit, for telephone systems where reverse battery supervision is employed, optically coupled semiconductor devices are used to control both the polarity and the charge on a nonpolar capacitor.  This capacitor is powered from a DC to DC converter and the capacitor serves the dual functions of a rectifier filter capacitor and a voice frequency (VF) bypass capacitor.  The voltage boost circuit charges the capacitor so that it aids the central office battery, thus extending the normal operating range of the central office.          Whenever the current in the loop drops below a predetermined threshold level, the voltage boost is removed by a rapid discharge of the aforementioned capacitor.  When the loop is closed, the capacitor is quickly charged to the full boost voltage with a polarity so as to aid, or increase, the current in the loop.                             - i -

Abstract: LAMINATED PROGRAMMABLE        MICROSTRIP INTERCONNECTOR       ABSTRACT OF THE DISCLOSURE    An electrical interconnector is formed of discrete laminate members.  The basic configura-tion has a printed circuit substrate member inter-leaved between two ground plane members.  Prede-termined first and second printed circuit conductor patterns are on opposite sides of the printed circuit substrate, each interacting as a signal plane with the particular one of the ground plane members that is juxtaposed to it.  The two pat-terns are interconnected by severable conductive means located at one or more predetermined loca-tions across at least one edge of the substrate.          Programmability is effected by severing one or more of the conductive means in the desired interconnection pattern.  The basic configuration when arrayed with other similar basic configura-tions provides modular construction.  Each basic configuration, hereinafter referred to sometimes as a section, in the array is separated from its adjacent section by another laminate member which is an insulator.  The spacer member and its associated adjacent sections are configured to form a raceway, i.e. a duct or channel, for run-ning insulated wire conductors which may be used, if desired, to interconnect predetermined ones of the printed circuit conductors associated with the interconnector.  The interconnector is adapted to have the terminals of electrical devices mounted along the laminar edges of the interconnector.

The mold is part of a rotating mechanism and lift frame for rotating and verti-cally stacking the panel when the panel is partially cured.          Reinforcing steel is put into a heated mold.  A layer of concrete is poured into the mold, forced into close and in-timate contact with the mold and through the reinforcing steel by means of a traveling auger, striker plate and vibrating screed; insulation board and shear connectors are placed in the mold, further reinforcing steel is then placed in the mold, and a second layer of concrete is poured into the mold and forced through the reinforcing steel, by means of the traveling auger, striking plate and vibrating screed, which at the same time as they force the concrete through the steel, produce a smooth finish on the non-mold contacting surface of the concrete panel.           The mold can be heated by means of heating tubes attached to the bottom outside surface of the mold.           When the panel has set, hydraulic cylinders pivot the mold with its contained panel on to supports and into a vertical position for stacking and storing the finished panel.

Abstract: ABSTRACT OF THE DISCLOSURE            A depository construction for receiving deposits at unattended banking equipment units in deposit-containing envel-opes, and for issuing receipts for such deposits to bank cus-tomers.  The customer activates the depository mechanism to initiate a deposit procedure by pressing a button, using a key or inserting a customer-identifying card at a banking unit. Activation of the mechanism opens an entry gate for a horizontal deposit entry slot to permit a deposit-containing envelope to be inserted into the slot, and energizes the drive mechanism of an envelope belt conveyor to transport the envelope through the mechanism.  As the trailing end of the envelope passes an entry sensor, the entry gate is closed and a conveyor exit gate is opened.  As the leading end of the envelope arrives at the exit end of the conveyor, an exit sensor energizes a printer beyond the exit end of the conveyor which stamps deposit data on the envelope.  Another printer prints similar data on a receipt while the envelope is being discharged from the conveyor.  As the trailing end of the envelope passes the exit sensor and drops to a deposit chest, the conveyor drive is stopped and the receipt is issued to the customer.

Abstract: ABSTRACT OF THE DISCLOSURE         A method and apparatus for destroying weeds growing in and around crop rows without destruction of crops growing therein.  A plurality of electrically conductive spring members are disposed in a generally horizontal plane and connected to a high voltage source of electricity.  The spring members have a spring constant such that relatively stiff crops plants will deflect the spring members while relatively flexible weeds will not deflect them.  Substantially all of the plants in and around the crop rows are contacted with current-carrying portions of the spring members by moving the spring members relative to the crop rows parallel to the crop rows.  A larger dwell time of contact is provided between the spring members and the relatively flexible weeds then the dwell time of contact between the spring members and the relatively stiff crop plant so that the weeds receive sufficient electrical energy to result in destruction thereof, while the crop plants do not receive sufficient electrical energy to result in destruction thereof.  The difference in dwell time is provided by forming each spring member so that it has one end connected to a supporting member and the first portion extending from the connected end making a first angle .alpha. with a line along the direction of movement of the spring member, and having a free end with a second portion adjacent the free end making a second angle .beta. with a line along the direction of movement of the spring member, the angle .beta. being substantially greater than the angle .alpha., and by disposing the connected end of the spring member between crop rows while the free end extends into a crop row during movement of the spring member to affect contacting.

Abstract: 46,788 CIRCUIT BREAKER WITH INTERCHANGEABLE  RATING ADJUSTER AND INTERLOCK MEANS              ABSTRACT OF THE DISCLOSURE         A circuit breaker comprises an adjustable trip unit having electronic circuitry for initiating a tripping command upon detection of overcurrent conditions.  The trip unit includes an externally accessible interchangeable plug in rating adjuster removably supported on the housing of the circuit breaker and secured by a threaded rod and tube. An interlock mechanism cooperates with the trip bar of the circuit breaker mechanism to insure that only when a com-patible rating adjuster is properly seated in the housing and the threaded rod is completely engaged within the threaded tube will the circuit breaker mechanism be removed from the trip-free condition.  Coordination of a proper rating adjuster with a corresponding trip unit and circuit breaker is achieved by coordinating the lengths of the rod and tube and the position of the threaded portions thereof such that only a rating adjuster which is electri-cally compatible with a particular circuit breaker and trip unit will properly engage the threads of the tube to remove the circuit breaker from the trip-free condition.
