Title: A method for shaping a body with an interior cavity
IPC: B23P13/00
Filed: 1943-04-30
Abstract: 566,355. Sizing hollow bodies by pressure. WRETBLAD, P. E. F. April 30, 1943, No. 6870. [Classes 83 (ii) and 83 (iv)] Hollow bodies, such as porous bearing bushes, have the bore brought to size without appreciably closing the pores by mounting the body on a mandrel, preferably of hard polished metal and compressing it from the outer surface. A porous bush a, that may have been made from sintered powders, is impreg. nated with oil and placed on a mandrel b which sizes the bore when a punch c forces the bush through a die d. In modifications, the closure on the mandrel is effected by converging pressures from dies in a press or by hammering. The bore need not be of circular cross-section.

Title: Improvements in or relating to radar display systems
Inventor: PLAISTOWE DONALD LEOPOLD
IPC: G01S7/12
Filed: 1962-02-23
Abstract: 956,813. Radar display systems. MARCONI CO. Ltd. Dec. 13, 1962 [Feb. 23, 1962], No. 7148/62. Heading H4D. [Also in Division G1] In a radar display system of the type incorporating a storage C.R.T., means are provided for producing a signal representative of the changing portion of a raster corresponding to the scanning raster of the reading beam of the storage tube intercepted by a line moving over the former raster in synchronism with the azimuthal variation of direction of the spacesearching aerial of the radar system and means are also provided for superimposing the produced signal in a video signal channel fed with output from the storage tube. In a first embodiment, the storage tube 8 writes the signal received from the receiver 7 with a radial P.P.I. type scan and reads with a television raster type scan under the control of line and field deflection units 9 and 10 and synchronizer 11. The units 9 and 10 also control the production of a television type raster R of uniform brightness on a C.R.T. 13 in synchronism with the read raster of the storage tube. The motor 2 rotating the aerial 1 also rotates, via lining up means, a disc 4 having a slot 5 therein. The slot thus rotates in synchronism with the scanning direction of the aerial. The radial portion of the raster R seen through the slot 5 is projected on to a photo-electric transducer 16 to produce a signal which, after amplification is added to the read output from the storage tube 8, in mixer 18, for application to a display tube 19 having a television type raster in synchronism with that of the storage tube and the C.R.T. 13. The display tube 19 therefore shows a television type display having a superimposed radial line rotating to represent the scanning direction of the aerial 1. The slot 5 may incorporate a graded light filter to cause the leading edge of the radial line to be brighter than the trailing edge. In a second embodiment, Fig. 2 (not shown), the radial line is produced by a radial deflection C.R.T. showing the direction of the aerial as a rotating radial line. The radial line is then viewed by a television camera incorporating scanning means controlled by units 9 and 10 and the output of the camera is added to that of the storage tube.

Abstract: 898,081. Discharge from a nest of cups. ROSE BROS. (GAINSBOROUGH) Ltd. June 8, 1959 [March 6, 1958], No. 7174/58. Class 78 (1). Cups 11 are discharged one-by-one from a nested stack in a magazine 12 by means of grippers 56 carried by intermittently rotating carrier 32, and are deposited upon chain conveyer 58, the pushers 57 of which convey the cups to a filling mechanism. The cups are freely supported in magazine 12 by abutments 13, the magazine being caused to slide periodically along shaft 18 by cam 27 acting through levers 24, 23. Grippers 56.-These are carried on respective arms 36, 37, extensions of which are connected by pin-and-slot at 41. Pin 41 carries roller 44 which is influenced by cam 46 so as to cause the grippers to pivotally grip. Additionally support 33 is provided for supporting the lowermost cup, being resiliently carried by springs 43. Operation.-With magazine 13 (and cups) withdrawn up to the left, carrier 32 indexes to swing a set of grippers 56 into position opposite the magazine. The magazine slides down to the right. The lowermost cup then abuts support 33, being positioned so that grippers 56 are able, under the influence of cam 46, to move inwards to engage and contract the leading part of the said cup. This permits magazine 12 to withdraw leftwards whilst abutments 13 thereon engage and thus withdraw the remaining cups with the magazine. The lowermost cup, held in grippers 56, is thus free of the magazine and is carried by carrier 32 to be deposited on conveyer 58.

Title: Infrared gas laser
IPC: H01S3/04
Filed: 1973-02-16
Abstract: 1355317 Lasers PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 16 Feb 1973 [21 Feb 1972] 7726/73 Heading H1C In a CO 2  infra-red laser, water vapour pressure in the active medium is maintained by a quantity of zeolite which is heated by the laser radiation. This avoids the need for a separate thermostatic control of the zeolite temperature since if the zeolite temperature increases the water vapour pressure will increase and the laser output will fall thus lowering the temperature. The zeolite may be incorporated in the front surface of a resonator mirror, as shown at 7 in Fig. 1, or in the rear surface as shown at 7 in Fig. 2. In this latter figure the water vapour reaches the active medium via hole 12, and because the mirror surface is not apertured there is no output distortion. The zeolite may also be in a cylindrical body which has a wire or plate in the laser beam, Figs. 3 and 4 (not shown), or in a bulb in the output beam, Fig. 5. This latter has the advantage that the bulb may be screened or its thermal dissipation altered. To simplify the tube construction of Fig. 5 a reflector, or end mirror 4, may be used to direct the output on to the zeolite.
