When the end member 1 is screwed on to the rod 7, the members 3, 4, 5 and 2 are placed on the rod, the middle of which is centred by an elastic sleeve 18 and they are aligned axially by interengaging ridges and recesses on adjacent ends. The members are heated and welded to form joints 20, 21, 22. Hot gas is then passed through a hole 6 and when a temperature difference of 200-300 C. between the rod and the members is reached, the member 2 is screwed as far as it will go. The supply of gas is stopped and when the rotor members have cooled, the members 2, 5 are interconnected by studs 17. The resulting compressive stress in the rotor can at least treble the fatigue strength of the welded joints. Finally winding slots are formed in the rotor.

Title: Improvements in and relating to weft-knitting
Inventor: PARR WILLIAM GEOFFREY
IPC: D04B1/14
Filed: 1964-12-24
Abstract: A weft knitted fabric is formed by feeding a substantially non-twisted multifilament yarn to a series of hooks which form in effect needles devoid of latches or other hook closing means such that they draw loops from the yarn fed to them.  The hooks are again advanced and take further yarn in their hooks and the same process is continued until the hooks become sufficiently loaded as to be incapable of accepting more yarn, whereupon some of the yarn and filaments thereof are cast off over the last drawn loops.  The resultant fabric is composed of drawn loops of yarn and filaments haphazardly disposed throughout the fabric.  To ensure that the loops of filaments are randomly disposed the hooks of the needles may be formed as slots in a blade and the slots may be of different depths or size so that some hooks accommodate more yarn than others.

Abstract: 1389020 Valves; antiskid systems GIRLING Ltd 27 Oct 1972 [12 Nov 1971] 52568/71 Headings F2V and F2F  A pressure-responsive control valve assembly, which is usable in an hydraulic braking system, has a ball valve member 33 operative to control flow between an inlet 35 and either one of two outlets 36 and 38. The valve member is urged, by the net force of opposed springs 13, 28, to engage a seating 16 thereby closing off outlet 36. Should the pressure of the flow then passing to outlet 38 rise above a predetermined value, then such pressure is operative to move actuator piston 26 against the force of spring 28 acting thereon until valve member 33 is caused, by spring 13, to engage seating 32 thereby to close outlet 38. A fall in pressure within the last mentioned outlet results in the system returning to the first state wherein outlet 36 is closed. When used in braking system, high pressure fluid is supplied to the wheel brake directly from a source connected to inlet 35 whilst outlet feeds an anti-skid system.

Abstract: 1471899 Facsimile systems; analogue-todigital conversion ROBERT BOSCH GmbH 11 Dec 1974 [24 Dec 1973] 53532/74 Headings H4F H3H and H4P A video signal representing successive points in successive scan lines of a scanned field is differentially encoded and the encoded signal quantized, the quantization characteristic being changed during a scan line n if a large difference signal is detected in the preceding scan line, such signal representing a substantial change of contrast, e.g. the edge of an object in the scanned field. The new quantization characteristic is maintained during scan line n for a period that embraces the difference signal representing the portion of the edge in that scan line, so ensuring that it is subjected to the new quantization even if the edge has a substantial slope. The difference signal comprises a series of digital or analog values each representing the difference of the values of the video signal at two adjacent picture points. Successive difference values at 11 are passed to a threshold unit 15, Fig. 2, and to a quantizer comprising threshold units 12-14. If a difference value exceeds, for example, 15% of the maximum possible difference value, and therefore represents the presence of an edge in the scanned field, unit 15 passes an edge signal to OR gate 29 and serially connected delays 20-23. Each delay 20-23 is equivalent to the scanning interval between two picture points. The edge signal causes delay 30 to reverse switches 16-18 after an interval corresponding to one scan line minus two picture points. The switches remain reversed for 5 points since delays 20-23 are connected to the OR gate input. The switches change the thresholds of units 12-14 such that coarse instead of fine quantization takes place. The coarse quantization lasts for 5 points and so exists when the corresponding edge occurs in the next line, even if the edge is substantially inclined to the scan lines. Unit 31 receives the output from each threshold unit and develops a signal for transmission.

In a particular arrangement, the element 21 has three metal layers of chromium, silver and chromium respectively, on top of a base layer of silicon dioxide on silicon. The workpiece plates 17, 19, 23 have a three-metal layer structure of the same dimensions as the control element. The infra-red radiation emitted, by the control element 21 is measured via quartz windows 27 by a thermometer 29 producing a voltage which is indicated, 31, and graphically recorded, 33. Different voltage levels are produced for the two different metals, and a substantial difference between the bottom chromium layer and the face, indicating the desired depth or end point of the etching process. Automatic electrical end-point sensing means may be provided. The control element need not have the same thickness of materials as the workpiece plates as long as its nature and thickness is known and the etching rate in comparison with that of the layers of the workpiece to be etched, is known. Suitably a control element layer structure is formed by the same process as that for the workpieces.
