Title: Feed control means for honing and like machines
IPC: B24B33/02
Filed: 1980-07-28
Abstract: Feed motion to a working member is controlled in a machine such as a honing machine. A honing block 30 is mounted on a support and movable radially into engagement with a work surface by wedges 22, 24, This is achieved by spindle 16 feed and lever 17 movement. The feed motion is controlled, independent of pressure, by a hydraulic dash pot 42 having a cylinder and piston one of which is pivotally attached 60 to the machine and the other of which is axially movable relative thereto. A spring 104 normally biasses the piston and cylinder together into a predetermined inoperative condition. An operator pedal is operatively connected via a lever 118 to a cam 120 and to the movable dash pot part and presets the cam and the dash pot to predetermined positions at the beginning of each machine operation. Cooperatively engageable cam 120 and cam follower are coupled with the movable dash pot part. A link member operatively connects the cam follower to an arm 38 abutting a collar 36 on the feed mechanism. Subsequent relative piston-cylinder movement is controlled by adjustable metered fluid flow therein to control the feed and honing block pressure. <IMAGE>

Title: Horn antenna feeder
IPC: H01Q19/08
Filed: 1980-12-23
Abstract: A horn antenna (1) having a wide angle of flare in its H-plane is arranged to provide a substantially constant beamwidth over a broad frequency range. For operation over a very wide frequency range (e.g. 3:1), the horn (1) is combined with a waveguide feeder (2) having ridges (13, 14) the heights of which decrease with decreasing distance from the throat (8) of the horn (1), reaching zero adjacent the throat (8). Over the majority of the frequency range, the feeder (2) operates only in the fundamental TE10 mode, but at the upper end of the range, the ridges (13, 14) themselves generate in addition the higher-order TE30 mode. To alleviate the degradation of antenna performance above the TE30 cut-off frequency, the feeder (2) includes a short length (9) of plain waveguide between the throat (8) and the adjacent ends of the ridges (13, 14). <IMAGE>
