Title: Improvements relating to pulse radar apparatus
IPC: G01S7/295
Filed: 1956-11-23
Abstract: 840,118. Pulse radar; radio direction-finding. COMPAGNIE FRANCAISE THOMSONHOUSTON. Nov. 23, 1956 [Nov. 25, 19S5], No. 35958/56. Class 40 (7). Pulse radar apparatus comprises directional receiving aerials 1, 2 having their directions of maximum sensitivity symmetrically disposed on either side of a line in a plane, a common local oscillator 7 and I.F. amplifier 14, separate mixers 5, 6, a switch 13 for feeding the outputs of the mixers alternately to the I.F. input in successive radar pulse repetition periods (p.r.p.s. ) and a comparator 24 deriving an error signal representing the deviation in the plane of an object from the line of symmetry between the aerials. The switching is accomplished by anti-phase square waves from generator 15 whose repetition period is twice the radar p.r.p. and which is synchronized from pulse generator 16 and frequency divider 17. Gating circuit 18 controlled by an adjustably-timed pulse from generator 19 selects the desired target range. Comparator 24 includes a circuit 25 which multiplies detector 21 output pulses by a square wave from generator 15, Fig. 3 (not shown), the resultant positive and negative pulse train being averaged in unit 26 to produce an output error signal which may actuate a control system 27 to orient the aerials until there is no error output. A.G.C. circuit 22 reduces I.F. output variations over a period long compared with the radar p.r.p. The I.F. output is monitored by cathode-ray tube 23. Two pairs of aerials may be used to give the deviation in mutually perpendicular planes.

Title: Machine for severing and applying predetermined lengths of tape
IPC: B26D7/26
Filed: 1972-08-01
Abstract: 1398391 Rotary cutting apparatus MINNESOTA MINING & MFG CO 1 Aug 1972 [2 Aug 1971] 35958/72 Heading B4B Apparatus for cutting strip material 12 into lengths and applying the lengths in spaced relationship on a travelling surface 14 comprises an applying wheel 18 with a peripheral speed equal to that of the surface, a vacuum system for engaging the tape end with the periphery of the wheel, a cutting bar 16 mounted on the applying wheel co-operating with a cutting blade 24 and means to feed the tape at a slower speed than that of the surface but to advance the tape end during cutting at the surface speed. The cutting blade is resiliently mounted on a second wheel. The surface 14 may be on a series of ribs. The cutter bars 16 are arranged on the wheel 18 which has an apertured periphery against which the strip 12 is drawn by vacuum. Strip is fed to the wheel from a roll 28 via rollers on a plate 44 pivoted at 46, the plate being oscillated by crank means 48, 54. The blades 24 are mounted on a wheel 26 so as to be pivotable on the heads of adjusting bolts 88 against springs 90, the blades being held normally against stops 94. Each blade assembly is carried on an arm 96 pivoted on the wheel for movement relative to it by a fixed cam 100. The blade cutting edge. 22 is angled, Fig. 6, and guide members 86 project from either end. The peripheral speed of the members 86 and edge 22 is slightly greater than that of the cutting edge 20 of each bar 16. In operation, the guide members 86 initially engage the bar edge 20 on either side of the strip and, owing to the speed difference referred to above, the blade is pulled off the stop. At the same time, the arm 96 has been allowed to pivot in the same direction (anticlockwise as shown) on the motion of the wheel 26. Normally the strip advances at slightly less than the peripheral speed of the wheel 18, causing slip, but during the cutting operation the plate 44 swings forward to permit speeding up of the strip advance. After cutting and prior to disengagement of the guide members 86 from the edge 20, the cam 100 pivots the arm 96 clockwise so that the stop 94 moves towards the blade to receive it as it slips free of the edge 20. A wheel 73 applies oil to the blades 24.

Filed: 1929-12-04
Abstract: 341,646. Milling screws. McLEOD, R. J., of Power Plant Co., West Drayton, Middlesex. Dec. 4, 1929, No. 37185. [Class 83 (iii).] In a milling - machine, particularly a thread-milling machine in which a hob and the work normally rotate at constant speed but in which the relative velocities may be varied and corresponding relative traverse imparted to the hob for the purpose of avoiding facets on the work, means are provided for automatically restoring the tool and work to predetermined axial and angular relations. The work-piece 5 shown as a double-tapered socket is mounted in a chuck on a spindle 8 which is driven through change speed and reversing gear 11 from a main shaft 10. From a shaft 12 of this gearing, the hob 21 is driven through gears 13, differential gear 17, shaft 18 and bevel gears 19, 20. The hob housing is mounted on a cross slide 24 carried by a longitudinal slide 25. A gear 27 driven from the train 13 drives through reversing bevel gearing 31 a shaft 36 which is connected by a longitudinal shaft and gearing 37, 38<1>, 38<3>, 40 to a lead screw 41 which, as described in Specification 310,240, [Class 83 (iii), Metals, Cutting], imparts a longitudinal movement to the hob to avoid the formation of facets. The hob-rotation is compensated for this movement by means of gearing 33, 34 connected to the differential casing 16. The shaft 36 is also connected by bevel gearing 42 and gears 43 to a cam cylinder 45 having a track 47 actuating a rod 49 provided with adjustable stops 50, 51 coacting with a bar 53 controlling the reversing bevel gearing 31. The bar 53 may also be operated from a handle 55 and its positions are determined by a lever 63 coacting with a notched plunger 66. In operation, the hob saddle 25 is adjusted by hand until the required starting position, such as the position to continue a thread already cut on one half of the blank, is reached. A dead stop is adjusted for this position and the stop 50 is adjusted against the arm 52 with the clutch 31 in neutral position. The cutting of the screw can then be effected, and when the differential movements are required to eliminate the facets the hand lever 55 is operated to engage the forward driving pinion 29. The cam 45 is thus driven and the rod 49 shifted until the stop 51 disengages the clutch. The hob slide 25 is then manually withdrawn, whereupon a projection 60 on this slide rocks the lever 63 to engage the reverse pinion 28 which reverses the lead screw, differential drive and cam 45 until the original positions of these parts are reached whereupon the clutch is agan moved into neutral by the stop 50. In a modification, the cam 45 may be replaced by a disc cam, and in a further modification, Fig. 5, the bar 49 carries a roller coacting with cam strips 73 on a drum 74.
