Title: Improvements in or relating to wireless direction finding systems
IPC: G01S1/02
Filed: 1937-07-09
Abstract: 498,417. Aerials. STANDARD TELEPHONES & CABLES, Ltd., andWAGSTAFFE, C. F. A. July 9, 1937, No. 19113. [Class 40 (v)] A radio direction-finding system uses an aerial system comprising three or more pairs of aerials equally spaced around a circle, each pair of aerials being connected to an associated field coil of a radio-goniometer or to suitably disposed plates of an oscillograph. Where three pairs of aerials are used the spacing between aerials of a pair can be À5# for an error of less than ¢‹ and the spacing can be increased to À75# if four pairs of aerials are used. The three pair aerial system can be used with three field coils A, B, C associated with a single search coil SC as indicated in Fig. 1, with three search coils SC1, SC2, SC3 connected in series or parallel and mounted on a common spindle as shown in Fig. 2, or with an oscillograph having three pairs of deflecting plates with deflecting axes at 0, 120 and 240‹. Alternatively the three channels can be reduced to two channels for connecting to an orthodox oscillograph, the conversion to two channels being effected by three special transformers T1, T2, T3 in which the primaries P1, P2, P3 are identical and the secondaries A1, A2, A3, B1, B2, B3 are also identical, the couplings between the various coils being defined in the Specification. The channels can be connected to a single amplifier channel as described in Specification 496,239.

Abstract: 632,869. Lathes. WARNER & SWASEY CO. July 18, 1947, No. 19231. Convention date, July 18, 1946. [Class 83 (iii)] [Also in Group XXIV] Indexing-mechanism for a lathe &c. comprises two identically-shaped and reverselydisposed cams 51, 52 which are rotated simultaneously and respectively engage a plurality of projections on the opposite faces of an indexible member 47 in such a way that the member 47 is driven by one cam 51 co-operating with the projections 48b &c. on one face of the member, while the cam 52 co-operates with projections 49b &c. on the other face so as to prevent over-running, the cams being provided with arcuate surfaces F, F<SP>1</SP> which respectively co-operate with adjacent projections 48b, 49b on opposite faces of the member 47 to maintain the member in an indexed position. A notch D is formed in each cam to hold the member 47 steady while the other cam is passing from a driving to a restraining function. The indexible member 47 is mounted coaxially with a work-, or too]-, turret on a shaft 24 and is clutched thereto at each end of an inoperative turret traverse (to the right in Fig. 3) by a pin 44. An electric motor 58 then rotates the cams through an electrical transmission device 59 and gears 64, 65, 66, 67 and 69, a switch ILS being actuated after one complete revolution to de-energize the cam drive. The transmission 59 is alternatively energized to rotate a gear 60 which through gears 61, 63 and a cam 37 traverses the turret until a switch FLS is actuated. A switch RLS controls the return movement of the turret. When, during the traverse, the clutch-pin 44 becomes disengaged, the turret is maintained in its position by dogs 30 which consecutively engage a guideway on the machine frame.

Filed: 1955-07-06
Abstract: <PICT:0807857/III/1> <PICT:0807857/III/2> Vacuum distillation apparatus comprises a surface of revolution which has an upright axis and is arranged to be heated, means for supplying liquid to the surface so as to flow downwardly thereover in a film, a member mounted for rotation about the axis, and a plurality of wiper elements mounted one above the other with respect to the axis of the member and arranged to rotate with the member, each element having an axial length less than the axial length of the surface and being free to move radially independently of the other elements so as to engage the surface under centrifugal force as the member is rotated. Distilland is pumped through a pipe 88 (Fig. 1) into a tubular shaft 37, which is rotated by a pulley 67, and then through a needle valve in an assembly 91 by pipes 109 to nozzles 111, the volume delivered to the nozzles being proportional to the pressure of the distilland. The distilland is sprayed by the rotating nozzles on to a heated cylindrical vaporization surface 61, down which it flows as a film which is thinned by wipers 116 mounted in channels 113 rotating with the nozzles 111.  The wipers 116 are loose in the channels 113 and shift outwardly by centrifugal force to contact surface 61.  Half the wipers have surface-engaging ports on their upper and lower edges with cut-back portions between, and the other half have cut-back portions on their upper and lower edges with surface-engaging portions between, the wipers being mounted in the same horizontal plane complementary to each other.  As the wipers rotate the surface-engaging parts thin the film on the surface 61, surplus liquid passing through slots in the wipers to be thrown back on the surface by centrifugal force and redistributed by the cutback portions and then rewiped again. The pressure of the wipers on the heated surface 61 is controlled by varying the speed of rotation of shaft 37.  Distillate condenses on a cooled coil of piping 47 and drips into a trough defined by a wall 28 and flows through an outlet 38.  Residue flows into an annular collector 59 and through an outlet 62.  A condenser 126 cools the lower wall 17 of the apparatus forming condensate which flows through the outlet 39.  A vacuum is applied through a conduit 33.  The upper part of the apparatus forms a high vacuum distillation unit and the lower part a low vacuum unit.  Both condensers 47 and 126 may be operated together to separate liquids of lower and higher boiling points from a mixture, or one or other condenser may be operated above.  In a modification the unit has a sloping wall.
