Filed: 1975-04-08
Abstract: 1503598 Antenna THOMSON-CSF 8 April 1975 [9 April 1974] 14435/75 Heading H4A An antenna whose axis OA may be directed azimuthally and elevationally has a radiating system beam, the radiating system having a privileged plane defined by the antenna axis OA and a beam symmetry axis ab, this latter axis being rotated about the antenna axis in a plane Q perpendicular thereto according to a function of the azimuth G 0  and elevation S 0  of the antenna, the system allowing a beam scan up to 20 degrees on either side of the antenna axis OA in the privileged plane aOb. As described, the major symmetry axis ab and privileged plane are maintained tangential to the circle generated by a point A due to the roll of a ship, on which the antenna is mounted, about Ox by computer operations on azimuth G 0  and elevation S 0  angles of a satellite which angles are known from the ship's position and heading. The maintenance parameter is the computed angle #. In an embodiment the radiating system comprises a 7 x 7 array of phase controlled elements (Fig. 3, not shown). The scanning angle (r, Fig. 5, not shown) may be computed from a knowledge of the roll angle. For small pitch angles about Oy, beam axis ab can be oscillated by an angle related to the instantaneous roll to maintain the antenna axis in the privileged plane for no roll conditions.

Abstract: 1,140,349. Vending Machines. WESTINGHOUSE ELECTRIC CORP. 6 April, 1966 [28 April, 1965], No. 15267/66. Heading G4V. A check-controlled, multi-column vending machine including a vend release mechanism for each column comprises an interlock means having a series of slides normally held locked in an end-to-end abutting relationship which, upon insertion of a check, are released to permit the operation of only one mechanism. The machine also includes means whereby, when a mechanism is being operated, a check deposited in the machine is returned to the user. Handles (15-20) (Fig. 1, not shown), each associated with a column are operatively connected with rotatable shafts 41 of the vend release mechanism which may be similar to that described in copending Specification 1,140,346. Each shaft has rotatable therewith a cam plate 81, having a cam slot 83 which receives a cam roller 82. The roller also moves in a stationary cam slot 84a. When the shaft is rotated clockwise(as shown in Fig. 7) the cam roller displaces a pivoted interlock slide operating lever 91 which engages between two slides e.g. 101, 102. Movement of the lever to the position of Fig. 11 is prevented by a locking bar 110 engaging a recess in slide 100. When a check is deposited in the machine a solenoid 113 is momentarily energized to raise the locking bar to a position in which its lower portion 112 is supported by a spring urged catch 114. Movement of the slides to permit actuation of one of the vend release mechanisms is then possible. The slides on being moved prevent actuation of another vend release mechanism. A portion 100a of a slide 100 upon movement engages with and pivots the catch 114 thus releasing the bar 110 which drops on to the upper surface of the slide 100. When the slide 100 is moved by spring 100b to the right after a vending operation the bar will again engage the recess in that slide. Coin return.-Movement to the right of slide 104 during a vending operation causes, via bell crank lever 105, switch 62 to condition a check accept and return mechanism 120 to return to the user any check deposited during the operation. Empty indication.-Each column has associated therewith a cam lever 51, the portion 51a of which engages an article, e.g. a bottle. The empty condition of a column is indicated by a button 22 forced outwardly by a cam 51d engaging the mid-point of a spring 72. Each lever 51 when in its empty position engages a notch 80 (Fig. 7), to prevent rotation of a respective shaft. When the machine is empty a bar 60 drops and actuates switch 62 thus causing return of deposited checks. Fraud, preventing.-Pressure applied to one of the handles will cause sufficient movement of the slide 104 to operate the switch 62 and condition the mechanism 120 for coin return.
