Title: An improved form-grinding machine
IPC: B24B5/16
Filed: 1944-02-01
Abstract: 574,471. Grinding. SUGDEN & CO. (ENGINEERS), Ltd., A. R., and SUGDEN, . A. R. Feb. 1, 1944, No. 1828. [Class 60] A form grinding-machine has the work and a pattern mounted on an arm pivoted about a vertical axis, the pattern being held yieldingly against a contour plate, which, together with the grinding-wheel, is movable to swing the arm about its pivot, thus causing the pattern to roll upon the contour plate and the work to be moved correspondingly in relation to the grinding-wheel; the work is rotated during the grinding operation. The machine comprises an arm c, carried by a bracket d pivoted about a vertical axis in a part attached to a base g, the arm carrying the pattern a and the work j, one vertically above the other, the work j being mounted between centres j<1>, j<2> and rotated by a flexible shaft j' and belt gearing from a motor h<4>. The motor h<4> also drives, through belt gearing, a cup-shaped grinding- wheel h, which is mounted on a slide g<1> movable on the base at right angles to the arm c ; the slide g<1> carries also a contour or rolling plate i pivoted at i<1> and adjustable by screws i<2>, i<3> so as to be vertically above the operative face of the wheel h. The wheel h is mounted on a second slide g<2> adjustable, to apply cut, on the slide g<1> by means of a micrometer screw g<3>; the arm c is acted upon, to hold the pattern up to the contour plate and the work up to the wheel h, by a flexible connection c<1> and a weight. Means may be provided to enable the arm c to be held away from the wheel h &c. for changing a piece of work and the part n carrying the centres for the tip ends of the pattern and work may be adjustable on the arm c to accommodate work of various lengths. In operation, the slide g<1> is moved towards the work by a screw m<1> and handle m to cause the pattern to roll on the contour plate i, a corresponding movement being given to the work in relation to the grinding-wheel. The wheel. may be trued by a diamond p carried by a block p<1> slidable along the arm c by a screw p<2>. Specification 480,661 is referred to.

Abstract: 1,141,065. Extruded clay pipes. HEPWORTH IRON CO. Ltd. 13 Jan., 1967 [14 Jan., 1966], No. 1876/66. Heading B5A. Pipes are manufactured from "dry" clay i.e. having a moisture content low enough that the pipes are rigid after compaction and that contraction on drying is less than 1% by densely compacting the clay particles and extruding the mass at a pressure in excess of 750 p.s.i. Apparatus comprises (Fig. 1) a vertical cylindrical chamber 3 having a piston 12 extending through a bore in a co-operating plug 11 and having an enlarged head 14 and vertically movable by cylinder 13. The chamber 3 and plug 11 are each also vertically reciprocable by pistons 5, 9. Initially, the top of cylinder 3 is raised above the top of plug 11, head 14 being clear of cylinder 3, forming a chamber (16, Fig. 3, not shown) for the clay particles. Head 14 is then forced down the cylinder 3 compacting the mass to a rigid form which is then extruded upwardly between the head and cylinder wall. Cylinder 3 is then lowered to expose the pipe which is then severed.

Upon admitting pressure air to a line 4, Fig. 1, the full force thereof acts on a disc 15 so keeping the moving closures 6 and 8 seated, as shown, whilst a chamber 5 between the closures is slowly pressurized via a restriction 3 or a cyclically-energized electrically - actuated valve. The closures 6, 8 may be joined by a lost-motion connection. When the chamber pressure attains a given value the pressure differential on closures 6, 8 is sufficient to unseat the former whereupon the pressure air in chamber 5 flows into another chamber 10 and acts upon a disc 11 so accelerating the valve-opening movement and ensuring that the closure 8 does not open the outlet 9 until the speed of the valve members 1, 6, 8, 11 and 15 is high; the contents of chamber 5 discharges through the outlet 9 as a pressure surge. The pressure on disc 15 then returns the valve member to the position shown. In a further form, a suction cup 17 (Fig. 3, not shown) is provided which may replace or be used with the disc 15, Fig. 1, and the valve member, which may be spring or weight loaded, is supported upon, and the interior thereof is vented by, a tube 20; the disc 11 and chamber 10 are also dispensed with. The closure 8 may coact with a flexible seat. The suction applied to the cup may be variable so as to control the frequency when a succession of surges is desired. In another form, the suction cup is replaced by a magnet.

Abstract: 1,165,283. Colour television. TELEFUNKEN PATENTVERWERTUNGS-G.m.b.H. 13 Jan., 1967, No. 2053/67. Heading H4F. The Specification describes colour television signal mixing and/or fading circuit arrangements, for fading out one colour television signal and fading in another, said two signals being frame and line synchronized but the chrominance carrier F for each signal being differently modulated in alternation line by line (e.g. PAL or SECAM), and said alternations not necessarily being synchronous. Thus in a PAL receiver, the PAL switch which is in phase with the initial signal, may be found to be in antiphase with the faded in signal. In one arrangement to overcome this, Fig. 1, the two signals (FBAS) 1  and (FBAS) 2 , although line and frame synchronized are seen to have their alternations of the chrominance carrier modulation from Fa to Fb, out of synchronism by one line period, and signal (FBAS) 2  is accordingly delayed by one line period at 21 to produce a signal which, when chosen by switch 7, can be fed to fading arrangement 10, for fading on to the end of signal (FBAS) 1 . In the arrangement of Fig. 2, the signals are PAL type signals, containing the chrominance carrier F and its conjugated complex F* on alternate lines. Filters 11 and 13 separate the chrominance carriers F2, F 2 *, F 2  . . . from the signal (FBAS) 2 , to leave the components (BAS) 2 . The separated chrominance signals are fed directly to terminal 3 of switch 7 and also to modifier 15, which forms at its output the mirror image signal of its input signal about the (B-Y) modulation axis (see Fig. 3). Signal F 2  thus becomes F 2 * and F 2 * becomes F 2 . The thus modified chrominance signals are fed to the second terminal 5 of switch 7. Means, to be described, determines that the signals on terminal 3 are in phase with the chrominance carrier signals in signal (FBAS) 1  and switch 7 accordingly adds these signals to the (BAS) 2  components in adder 12, to produce the complete colour signal, which can be applied to fading arrangement 10. The PAL signals may comprise chrominance synchronization signals containing oscillations whose phase is switched over from line to line. In such a case, the connection of switch 7 to terminal 3 or 5 is controlled by a phase comparator 19, Fig. 4 (not shown) determining whether the oscillations in the two signals are in phase or in antiphase.
