An antenna lens is associated with a cluster of horns mounted symmetrically on each side of the lens axis. Scanning is effected electrically by the sequentive correction of the horns to the receiver or transmitter. The horns are coupled by a waveguide system to the receivers, through waveguide ferrite switches. The latter line each controlled by an associated electromagnet which is energized through a commutator or switch. As the commutator is moved progressively round its angle of rotation the magnets are energized in turn, and the horns coupled in turn to the receiver or transmitter. Those horns not so coupled are connected to matched terminations which absorb received signals.

Title: Improvements in or relating to grinding or abrading machines
IPC: B24B47/20
Filed: 1936-09-19
Abstract: 470,139. Grinding. TRIGGS, W. W. (Norton Co.) Sept. 19, 1936, No. 25551. [Class 60] In a cylindrical grinding-machine means are provided for automatically increasing the rotational speed of the grinding-wheel as this wears, in order to maintain a constant peripheral speed. The machine comprises a base 10 carrying a grinding-wheel 11 belt-driven by an electric motor 14. Slidable on ways 19, 20 is a work carriage 18, movable towards and from the wheel by a screw 21, the work 25 being supported by head- and tailstocks 26 on a slide 27 movable on longitudinal ways 28, 29 on the carriage 18, so that the work may be traversed axially, either by hand, through rack gearing 30 ... 33, or automatically. The speed of the motor 14 is controlled by a rheostat 37, the arm 38 of which is moved by a chain 46 passing round a sprocket 45 rotatable on a stud 41 carried by the base 10. On the stud also is mounted a pinion 40 engaging a rack 39 on the carriage 18, the pinion 40 either being fixed to the sprocket 45 or connected thereto with lost motion by a stud 50 on the pinion movable in a cut-out portion 51 of the hub 52 of the sprocket. In operation, the carriage is advanced to the grinding position, and if the wheel has worn down, so that its peripheral speed has fallen, the pin 50 engages the end of the slot 51, thus causing rotation of the rheostat arm 38 to increase the speed of the motor 14 ; the lost motion arrangement allows withdrawal of the carriage 18, for removal &c. of the work, without alteration of the setting of the rheostat, but when the carriage is withdrawn sufficiently to allow the insertion of a new full-sized wheel, the speed of the motor is reduced correspondingly. In a modification, the wheel is movable towards and from the work, the speed controlling mechanism being operated by movement of the wheel carriage. In order to adjust the initial speed of the motor, the sprocket 45 is adjustably carried by the hub 52 mounted on the stud 41.

[Also in Group XI] Apparatus for producing hollow structures includes a number of spaced apart pairs of elongated co-operating high-frequency electrodes, means for supporting and moving a pre-folded structure towards the electrode pairs such that the overlapping structure portions are subjected to mechanical pressure and heating. Separate pairs of elongated electrodes 13, 14 are carried by oscillator units 8, each adjustable along a bracket 9 by a hand wheel 10 and toothed gears 11, and a platform 15, which may be adjusted vertically, supports an insulated block 38A over which the workpiece, i.e. a box-like structure, Fig. 5, is placed. A pin 21 on a slide 23 carried on two horizontal rods 24 passes through a slot in the platform and fits centrally within a bore in the block. By depressing a pedal 25 the pin and block are moved towards the electrodes by levers and links 26-28, and two of the overlapping workpiece parts 40 are engaged by the separate electrode pairs. Simultaneously a switch 33 is operated, by the movement of the link 28, to effect the supply of power to the electrodes which co-operate with counter electrodes secured in the block adjacent the parts 40. The two remaining junctions 40 are welded after rotating the block about the pin and repeating the operation. A spring 36, Fig. 4, returns the pin to its rearward position. The electrodes may be resiliently or pivotally mounted on the oscillator units, and in an alternative construction the electrode groups are arranged on opposite sides of the platform.
