Title: Improvements in and relating to directional aerials
IPC: H01Q1/18
Filed: 1946-03-06
Abstract: 612,329. Electric control systems. BRITISH THOMSON-HOUSTON CO., Ltd. March 6, 1946, No. 6995. Convention date, March 27, 1943. [Class 40 (ii)] [Also in Group XL (c)] A gyroscopically - stabilised aerial designed for mounting upon a ship is carried by a turntable upon which is journalled a frame having an axis perpendicular to the vertical plane containing the directive axis of the aerial system, and gyroscopic means for maintaining the intersection of the plane of the frame with the said vertical plane horizontal, means being provided to maintain the elevation angle of the directive beam at a predetermined value relative to the gyroscopically-stabilised frame. The antenna comprises a radiator 4 connected to a transmission line 3 and a parabolic reflector 5 mounted in trunnions 6 carried by' supports 7 mounted on a rotatable carriage 1 and adjustable in elevation by a toothed sector 28 secured to the reflector. The turntable 1 is driven by a motor 8 which is controlled by a selsyn follow-up system, Fig. 4 (not shown), to position the directive axis of the aerial in azimuth in accordance with the preset position of a control handle. The elevational motion is controlled by a motor 25 driving the toothed sector 28 and rotating the stator 31 of a selsyn 32, Figs. 3 and 6, so that the position of the stator corresponds to the elevation of the directive axis of the antenna. The stator 31 is journalled in a housing 34 fixed to a U-shaped frame 35 bolted to the turn-table 1. Rotatably mounted in the frame 35 is a frame 36 having a shaft 37 fixed to the rotor 38 of the selsyn 32. The frame 36 is held horizontal in a plane parallel to the vertical plane, including the directive axis of the antenna by a gyroscope which is carried by a frame 39 pivoted to the frame 36 on a horizontal axis parallel to the directive axis of the antenna and which includes a stator fixed to the frame 39 and a rotor 40 surrounding the stator and provided at its lower end with a hemispherical damper 41 associated with a permanent magnet 42 supported for universal motion from the frame 39. The magnet has a short period of oscillation and if the axis of the rotor 40 deviates from the vertical, the drag, due to eddy current in the damper 41, causes the gyroscope to process towards the vertrical, thus bringing the frame to the horizontal position. The elevation of the antenna is controlled by a selsyn 43, having its stator 44 connected to the stator 31 and having its rotor 45 adjusted by handle 46 so that any phase displacement of the.rotor 38 relative to its stator 31, as compared with the preset selsyn 43, generates a voltage which is amplified and rectified at 47 and supplied to the fields 48 of the generator 30 to produce a control voltage for the motor 25 to rotate the stator 31 and to move the antenna to decrease the displacement.

Filed: 1974-02-19
Abstract: 1453687 Automatic exchange systems SIEMENS AG 19 Feb 1974 [22 Feb 1973] 7455/74 Heading H4K In a t.d.m. system employing a 4 wire switching network of the Time-space-Time format means are provided in the crosspoint space switching section for indicating a double connection to an intermediate t.d.m. highway. As is well known, incoming t.d.m. highways KL1-KL15 are coupled via respective stores to the "horizontals" of a crosspoint switching matrix. However instead of the "horizontals" being directly connected by crosspoint switches to the "verticals" or intermediate highways, each set of crosspoints, e.g. 1K1-15K1, 1K2- 15K2 &c. giving access to a respective one of the intermediate highways is connected to the inputs of an OR gate OZ and a parity generator PG. In operation the parity generator produces an output 0 in the presence of a binary 1 on none or an even number of its inputs and a binary 1 in the presence of a binary 1 on one or an odd number of its inputs. Hence, if, during any time slot, two (or on even number) of the crosspoints, e.g. 1K1-15K1 giving access to the same intermediate highway are open to pass PCM binary codes, there is a high probability of a binary 1 occurring on two (or an even number) of inputs to OR gate OZ and the parity generator PG. The occurrence of such an even number of binary ls causes a binary 1 to be produced at the output of an exclusive OR gate EG due to the presence of different binary signals at its two inputs. This signal is used to give an indication of a double connection for if no signal is present at the output of any of the crosspoints extending to the same intermediate highway the inputs to EXCLUSIVE OR gate EG will both be binary 0 or if only one of the crosspoints has a signal at its output the inputs to EXCLUSIVE OR gate EG will again be identical. It is emphasized that because each connection involves two incoming highways and two outgoing highways GL1-GL15 due to the four wire operation, the possibility of a double connection for both directions is guarded against.

[Class 100 (i).] Sheets, envelopes, &c. are fed to printing, counting, gumming, and like machines from a spring or gravity pressed pile 2 supported on an adjustable inclined support 9 which is arranged so as to form with the periphery of a feed roller 4 a curved channel 12, the depth of which is adjusted in accordance with the thickness of the sheets. A support 7 for the pile is similarly adjustable. A frictional feed roller 4 which is formed with a rubber, gelatine, or like frictional portion 6, and with a smooth portion 5, separates the lowermost sheet 11 and draws it through the channel 12 into contact with a feed roller 22 co-operating with the roller 4. The roller may be formed with a plurality of alternating smooth and rough parts. A spring 13 finally assists the discharge of the separated sheet to the machine. The spring 13 is supported by a strut 14 which also supports a spring 16 which bears against the upper part of the channel 12 and serves to prevent double feed, and keeps back the succeeding sheet until it is engaged by the surface 6 at the next rotation of the roller 4. The separation of the sheets may be assisted by suction apertures formed in the surface 6 and controlled by valve means. Or the separation may be effected entirely by suction.
