Title: Manufacture of can bodies
IPC: B21D19/12
Filed: 1971-07-29
Abstract: 1348287 Flanging; rolling; making cans SWISS ALUMINIUM Ltd 29 July 1971 [31 July 1970] 35792/71 Headings B3E B3A and B3M A stepped rim on a seamless metal can is made by forming a rim 39, Fig. 6, on the free edge of the can by rolling and then causing metal to flow from the rim to a cylindrical portion 9, Fig. 7, being formed adjacent the rim with a diameter greater than the remainder of the can. In operation a mandrel 11, Fig. 3, is placed inside the can and a pressure roll 25, Fig. 4, moved into engagement with the can wall. The mandrel and roll are then rotated in opposite directions and on further displacement of the roll towards the mandrel, a cylindrical part 12 of the mandrel, having conical surfaces 18 and 19 which engage with spring biased conical surfaces 20 and 21, is shifted eccentrically with respect to a shaft 15 to form the rim 39. Upon further movement of the roll towards the mandrel, an annulus 30 having a conical surface 31 engaging a spring biased bush 33, is moved eccentrically with respect to a roller shaft 26, and at the same time the part 12 of the mandrel become more eccentric in relation to the shaft 15. Thus the cylindrical portion having a diameter greater than the remainder of the can is formed. During formation of the cylindrical portion metal flows into the portion from the rim 39.

Abstract: 1527728 Determining the spatial variations in transmissivity of a body PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 3 Sept 1975 [6 Sept 1974] 36273/75 Heading H4F In a device for determining the transmissivity variations over the volume of a body 4, an X-ray or a radio-active source 1 is positioned behind apertured attenuators 1, 2, to provide a wedgeshaped radiation beam. The radiation passes through the body 4 to be received by a row of photodetectors 6, whose sensitive areas are immediately adjacent one another, positioned along a circular arc. Each detector has a narrow field of view. The whole source-detectors arrangement may be rotated about the body with the source being switched on or exposed at predetermined angular positions. A further row of detectors may be provided in a direction perpendicular to the plane of the drawing. An additional detector may be positioned to receive the radiation directly, the further detectors outputs being ratioed with the row detectors 5 outputs to provide measurement values independent of intensity variations. Alignment and adjustment of the device may be achieved by means of an optical device (not shown) which is attached to the radiator and which emits three light rays corresponding to the outer extremities and the bisector of the wedge shaped X-ray beam. In Fig. 2 there is provided a number of radiators 11 ... 21 arranged in a circle about the object 4 with corresponding diametrically opposite rows of detectors 51... 61.

Title: A process for separating butylenes from butane
Inventor: BROUGHTON DONALD BEDDOES
IPC: C07C7/10
Filed: 1959-10-30
Abstract: Butane, butene-1 and butene-2 are separated from a mixture of C4 hydrocarbons by contacting with a solvent which preferentially dissolves the butenes to obtain a butane raffinate, introducing the extract of butenes into a stripping zone wherein the ascending vapours are contacted with solvent provided by the extract and from which butene-2 is obtained as a vapour side stream, solvent is obtained as bottoms and is recycled and a mixture of butene-1 and butane is obtained overhead and is subjected to fractionation to recover butene-1 overhead.  If isobutylene is present it is recovered with the butene-1; if isobutane is present this will be recovered partially with the butane and partially as overhead from the fractionation butene-1 being recovered as a side stream.  Many oxygen-containing organic solvents are specified, preferred being aqueous methanol containing 2%-30% by weight of water.  The extraction is effected at 5 DEG C.-65 DEG C. and 10-50 atmospheres in the liquid phase.  The stripping and fractionation may be effected in a single tower having at a mid-point a tray which collects liquid bottoms from the fractionation, this liquid being passed to the extraction process at a point between the point of introduction of the hydrocarbon feed and the point of removal of the extract.

Title: Improvements in or relating to apparatus for producing a display of information on an oscilloscope
Inventor: HASLETT ROY WILLIAM GEORGE
IPC: G01S7/534
Filed: 1959-10-30
Abstract: 897,969. Echo sounders. KELVIN & HUGHES Ltd. Jan. 26, 1961 [Oct. 30, 1959], No. 36970/59. Class 40(7). [Also in Group XXXVI]  Apparatus for displaying items of signal information received during recurring time intervals comprises selector apparatus adapted to select the information received during predetermined and corresponding portions of the time intervals, recording apparatus adapted to record the selected information along a closed track on a recording medium, the track length accommodating information from a predetermined plurality n of the time interval portions, erasing apparatus adapted to operate once during each of the time intervals for a period equal to one of the interval portions so as to erase the recorded information from the earliest interval portion recorded on the track, and means which reproduce the recorded information and display it on n lines of a raster such that the display on the line at one end of the raster represents the latest information and that on the line at the other end of the raster represents the information received n time intervals earlier. The invention is described as applied to a fish-finding ultrasonic pulse-echo sounder in which the display of echoes e.g. FI, Fig. 2a, with a predetermined range 23, Fig. 2b, of the sea bed is given, during successive pulse repetition periods, on successive lines of a raster on cathode-ray tube (C.R.T.) 30 by intensity or deflection modulation thereof. Waveform, Fig. 2b, is derived from input, Fig. 2a, by the means 12 disclosed in Specification 785,001. Magnetizable drum 16 rotation period is made slightly less, Fig. 2c, than the period between adjacent porches of waveform, Fig. 2b, and erase head 17, recording head 18 and reproducing heads 19, 20 are disposed at the time intervals indicated, Fig. 1. Pulse 23 switches on erase oscillator 21, triggers generator 31 (see also Fig. 2h) which feeds a frame time base charging circuit 32, and gates "on" signal, Fig. 2a, to recording amplifier 24. Circuits 26, 27 are fed from head 19 and yield waveform, Fig. 2f, which is differentiated to trigger line time base generator 29. The output, Fig. 2k, of head 20 is mixed with the pulse train, Fig. 2j; derived in generator 29 and with waveform, Fig. 2h, such that when the latter two waveforms are simultaneously positive waveform, Fig. 2k,  intensity-modulates the C.R.T. To obviate irregular spacing of the lines on the C.R.T., arising from irregular spacing of recordings on drum 16, the frame time base circuit utilizes a constant current pentode charging a capacitor, the pentode being rendered conducting each time waveform, Fig. 2j, becomes positive and the capacitor being discharged at the times X, Fig. 2h. Head 18 may be used also to replace head 19. C.R.T. beam deflection modulation to replace intensity modulation is provided by inserting an additional mixer between generator 33 and the Y-plates and feeding that mixer with the output of amplifier 34.
