Title: A phase shifter for a phased array antenna
Inventor: THOMAS LOUIS DAVID
IPC: H01Q3/36
Filed: 2009-05-15
Abstract: A phase shifter comprises two coupled 180 degree hybrids H1, H2 with an interposed phase shifting delay element D 1. The input signals are of equal amplitude but are phase displaced by a first angle. The phase shifter provides an input-output phase shift which is substantially proportional to the product of the first angle and the angle of the phase shifter D1. The 180 degree hybrids may comprise quadrature hybrids with series 90 degree phase shifters (figure 5). The phase shifters of this form may be deployed in a phased array antenna feed network (figure 10), each phase shifter (PM1 -PM4) having a fixed delay and receiving signals from a corporate feed network (204) having a single controllable phase shifter (212) effecting beam steering. A phase profile to reduce sidelobes may be applied to the radiators by fixed phase shifters (FP1-FP10), the phase profile increasing in magnitude and alternating in sign with distance from the array centre.

Filed: 1931-04-02
Abstract: 380,081. Rectifying. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. April 2, 1931, No. 10064. Convention date, April 3, 1930. [Class 38 (ii).] An arrangement of rectifiers comprises one or more pairs. of thermionic or static contact rectifiers connected or influenced in the same sense with respect to a " controlling current," and in opposite sense with respect to a " current to be controlled.'' The object is to " pass or withhold " the controlled current " synchronously with the controlling current," for A.C. measurements &c., or for D.C. circuits " in the manner of a relay." Current, voltage and phase-displacement measuring apparatus is described. In Fig. 1, rectifiers 2, 3 connected in like sense in the controlling circuit fed from the source A may be balanced for any inequality by a resistance slider 5, the points 5, 11 being normally at the same potential. A measuring instrument 8, and controlled source B functioning therewith, are connected to the points 5, 11 so that the rectifiers are in opposite sense in the controlled circuit. Current limiting and balancing resistances 4, 9, 10 are provided. The source A may feed two transformers connected to provide the correct rectifier sense, and the rectifiers can be connected so that only one half of the current is allowed to flow in the controlled circuit, the other half being shortcircuited. Fig. 6 shows an arrangement wherein one half of the controlled current is effective on a bridge connection A, B and the other on a bridge C, D. In order to prevent interference between the bridge circuits, they may be connected on the controlled or controlling side through a transformer having two secondary windings. Both halves of the controlled current may be utilized with a circuit as shown in Fig. 9, and this circuit may be modified on lines indicated above as regards its resistance and transformer connections. Fig. 11 shows an arrangement for measuring power factor, the rectifier bridges being supplied with a voltage corresponding to the voltage of the network 40, 41 and also with a current proportional to the network current. The sine component can be measured by rotating the phase of the network voltage.

Abstract: 590,859. Centrifugal governors. MASSEY MACHINE CO. April 23, 1945, No. 10203. Convention date, Sept. 28, 1944. [Class 57] In a centrifugal governor, four weights 18-21 are connected to crossed levers 22, 24 mounted on a pin 28 on the driving shaft 10 and also connected to the shaft 10 by links 30-33 that are parallel to the levers 22, 24 so that as the weights expand, they maintain the same attitude. The weights 18, 19 are connected by links 37, 39 to a rod 38 that carries a trunnion sleeve 46. A lever 50 is pivoted to the casing and to the sleeve 46 and is loaded by a spring 58. The tension of the spring 58 is adjustable by moving the abutment 59 by bevel and screw gear and the point of application of the spring to the lever 50 is adjustable by rotating the screw 65 through pinion 92 and bevel gear 93, 94. A wheel external to the casing carries the pinion 88 and is pressed inwards to engage the pinions 88, 92 to make this adjustment. In a modification shown in Fig. 4, the governor has two weights 108, 109, each connected to the shaft 100 by a pair of levers 110, 111 and 112, 113 that are parallel so that the weights maintain the same attitude. The lever 130 is loaded by three springs 134, 135, 136 of different strengths. Adjustment of the rod 140 by the bevel gearing determines which abutment 150, 151 shall be effective and which spring shall be operative to load the governor. In a further modification the loading springs are mounted between the weights.

Title: Improvements in taper roller bearings
IPC: F16C19/34
Filed: 1934-04-07
Abstract: 417,768. Roller bearings. SKERRETT, H. N., 24, Temple Row, Birmingham.- (Timken Roller Bearing Co. ; Denber Avenue, Canton, Ohio, U.S.A.) April 7, 1934, No. 10548. [Classes 12 (i) and 12 (ii).] A taper roller bearing has one of its bearing members 1, 4 provided with ribs 8, 9 at its opposite ends which closely confine the rollers 3 and are circumferentially opposed to the other bearing member with such a slight clearance that the parts act as plain bearings in the event of deformation of the rollers. In Fig. 1, the ribs 8, 9 are on the bearing cup and have cylindrical peripheries so close to the cylindrical parts 6, 7 of the bearing cone 1 that under heavy loads or shocks, these parts act as plain bearings. Lubricant supplied through the journal member to radial passages 10 opening at the small ends of the rollers passes to their large ends by the pumping action of the rollers themselves. The ribs 8, 9 may have conical peripheries, in which case the cone 1 has a single conical surface. In modifications, the ribs 8, 9 are on the bearing cone, or both bearing members have ribs, the adjacent cylindrical peripheries of which are located approximately at the axes of the bearing rollers. The latter form has a separate rib at one end of the cone. Fig. 6 shows a double-row bearing, the inner bearing-member having end ribs 8<d> adjacent the small ends of the rollers and a low central thrust-rib 30. A modified doublerow bearing has the end ribs and the central thrust rib which engages the large ends of the rollers formed on the bearing cups. In some forms, the bearing may be made self-contained by making the diameter of the cylindrical peripheral portion of one of the ribs different from that of the circle formed by the ends of the rollers over which the said portion must be pressed in assembly.
