Abstract: 1,110,299. Digital electric data processor. STANDARD TELEPHONES & CABLES Ltd. 12 Nov., 1965 [16 Nov., 1964], No. 48109/65. Heading G4A. A digital electric data processing system includes means for examining the output of a portion of the equipment, means for detecting an error in the output, and means for converting all error-free elements of the data associated with that portion of the equipment into an alternative form in which any element previously in error will now appear error free. As described data is accompanied by Hamming check bits and possibly by a simple party bit and detection of an error causes all the bits but the faulty bit (assuming only a single fault at a time) to be complemented so that the word then present is the correct complement of the original word. A further bit may be included to identify whether the word is complemented or not to cause the appropriate processing to be carried out on the data.

Abstract: 1,208,563. Dispensing liquids. AVERY-HARDOLL Ltd. and BECK & CO. (METERS) Ltd. 20 Oct., 1967 [1 Nov., 1966], No. 49003/66. Heading A4T. [Also in Divisions B1 and F1] In apparatus dispensing bends of two liquids, e.g. petrol or petrol and oil, the flows are controlled by two variable capacity meters 14, 16, Fig. 1, having their shafts connected at 70 and having means 62, 64, 72, 74 for changing their capacities. Motor driven pumps 2 deliver the two liquids through conventional meters 6 to the flow controllers 14, 16 preferably in the form of positive-displacement variablecapacity meters and then via a pressure regulator 18 tending to reduce the pressuredifferential across the controllers and thence by concentric hoses 26 to nozzle 22. Mechanical linkages 8 from the meters 6 actuate a quantity and price computer 9 and linkage 80-86 sets the price computer according to the blend selected by adjustment of the relative capacities of the controllers at 74. Each controller comprises radial vanes 24, Fig. 3, with their inner ends passing through slots in rotors 34 and bearing on fixed rings 30 via roller bearings 32 and their outer edges sealing with the inner walls of casing 48 assisted by springs 42 and provided with oil seal chamfers 66 facing away from inlet 58. Rotors 34 are mounted on spindle 40 which is eccentrically mounted in bush 54 rotatable by blend selector rack 64 whereby the volume swept by one set of vanes varies inversely with that swept by the other set. The regulator 18 acts so that, when the pressure differential increases across say controller 16 holding flow back, increased inlet pressure on valve 90 from controller 14 and increased inlet pressure to controller 16 via conduit 102 acting on diaphragm 98, tends to close valve 92 and reduce the differential and leakage in controller 16.

Abstract: 1498089 Corrugating sleeves ANDERSONCOOK Inc 3 Dec 1975 [2 Jan 1975 21 Aug 1975] 49635/75 Heading B3E A thin-walled sleeve is corrugated to form internal and external splines by rolling it on a toothed mandrel between opposed elongate toothed dies. In Fig. 1, the mandrel is supported between a head stork 20 and tail stork 24 in the gap between dies 26, 32 reciprocated in synchronization, the gap being adjustable by pillars 36 and nuts 38. In Fig. 2, the head and tail storks have arbors 54, 56, shafts 58, 60 of which are received in bore 50 of the mandrel 40. The mandrel supports two workpieces 42, each having a sleeve portion 46 and an annular end portion 44 which is kept flat during spline formation. The mandrel may be slightly expandable to facilitate removal of the splined workpieces. The teeth on the dies 26 are in groups of successively increasing height, Fig. 12, the leading group having a height Ha of at least 75%, preferably over 90%, of the finaltooth height Hf. Each group of teeth extends for a distance at least equal to half the mandrel circumference. The profile of the first group of teeth 34a has a flat 78 and chamfers 74, 76. The second group 34b is of rounded profile, and the third group 34c of rounded profile more nearly approaching the final profile. The remaining groups have the same profile as the final group, but truncatad at the root. All teeth have a common root line 66. All teeth may extend the full width of the die, apart from teeth 34s<SP>1</SP> on one die, Fig. 14, which engage a corrugated sleeve 52 on the mandrel, Fig. 2, to ensure correct relative movement between the dies and mandrel at the start of die movement before splining begins. Fig. 14 shows a modification in which the teeth of groups a to e are of progressively increasing length, so as to form each spline progressively from its centre outwardly. In other alternatives, each spline is formed progressively from one end, either the end near the portion 44, or the other end. The splines may extend right up to portion 44, or leave a ring near portion 44 unsplined.

Abstract: 1,242,420. Retractive switches. ROBERT BOSCH G.m.b.H. 28 Oct., 1968 [14 Nov., 1967], No. 51003/68. Headings H1A and H1T. A rotary key-operated switch, suitable for use as a combined ignition and starting switch for motor vehicles, having an "off" position, O, a first "on" position, Z, and a second "on" position, S, from which it retracts to the Z position on release of the operating key, is provided with a latch lever 20 to prevent movement of the rotary switching member 14 from the Z position to the S position unless it is first moved to the "off" position O. A ball detent 18 co-operates with notches 17 to locate the O and Z positions. The lever 20 is pivoted at 21 and has a projecting wall-like portion 24 which projects further at 23 such that portions 24 and 23 co-operate respectively with cams 25 and 22 on the member 14, the cam 22 being able to pass freely over the portion 24. A spring arm 19 normally urges lever 20 anticlockwise. As shown (Fig. 5) the member 14 has been moved into the Z position from the O position and can be moved further anti-clockwise to the S position wherein the cam 22 engages portion 23 to move the lever 20 over-centre with respect to spring arm 19 which then urges lever 20 clockwise, bringing the nose of portion 24 into engagement with the surface of member 14 behind the step 26 (Fig. 6, not shown). On release of the operating force a spring (27, Fig. 1, not shown), restores member 14 to the Z position and spring arm 19 causes the portion 24 to latch in front of step 26 (Fig. 7, not shown), thus preventing anti-clockwise rotation of member 14 to the S position. If member 14 is now turned back to the O position the cam 25 engages portion 24 to restore the lever 20 (Fig. 4, not shown) and the member 14 can again be moved to the Z and S positions.
