Title: Improvements in, or relating to, holders for wig blocks
Inventor: JOHNSON ALAN SIDNEY
IPC: B23Q1/54
Filed: 1966-07-05
Abstract: 1,206,104. Holders for wig blocks. A. S. JOHNSON. 2 Oct., 1967 [5 July, 1966], No. 30130/66. Headings A4H and A4V. A holder suitable for supporting a wig block comprises an inherently rigid stem 29 extending upwardly from a base 11 which comprises a foot 12 and a substantially cylindrical piller 13 projecting from the centre of and perpendicular to the foot, the head of the pillar being threaded externally and formed in its end face with a concentric depression in which a ball 30 on one end of the stem 29 seats and being surrounded and engaged by an internally threaded cap 23 having in its crown a concentric aperture, so that the pillar head, cap and ball form a ball and socket coupling beyond which the stem extends, the ball being releasable by manual rotation of the cap about the pillar head to enable the stem to be adjusted angularly and/or rotated about its longitudinal centre tine and subsequently clamped between the head of the pillar and the crown of the cap to lock the stem to the base. In addition to seating on a depression in the pillar head, the ball may seat on the periphery of the aperture of the crown of the cap or on a lip protruding into the interior of the cap from the periphery of the aperture, or on the internal periphery of a non-metallic ring 28 engaged in an internal circumferential recess in the wall of the cap. The pillar 13 may be provided with a shallow counterbored recess 33 so that a wear resisting non- metallic disc may be inserted to increase the frictional force preventing rotation of the ball. The wig block itself is provided with an internal blind bore whereby it may be socketted on to the stem, and the stem is formed with circumferential grooves which may be fitted with resilient O rings which project from the surface of the stem to enable the wig block to be held firmly.

Title: An improved method of planing helical teeth, more particularly for bevel gears
IPC: B23F1/04
Filed: 1920-10-25
Abstract: 153,001. Brandenberger, H. June 7, 1919, [Convention date]. Gear-cutting. - Helical gears of large angle are planed by a process in which, during the interval between successive working strokes of the reciprocating tool, the uniformly rotating blank moves through a number of pitch intervals which is incommensurable with the number of teeth in the wheel to be cut. In cutting a 25-tooth helical bevel A, as shown in Figs. 1 and 2, the stroke of the tool is represented by the line 1-2. The line of cut is indicated by the portion 13, 14 of the line 12, 13 - - 18, and the blank rotates through seven pitch intervals between successive working strokes. The tool thus cuts all the teeth in seven revolutions of the blank without the use of dividing mechanism.

IPC: H02M3/04
Filed: 1962-08-09
Abstract: 1,059,163. Automatic voltage control. WHITWORTH GLOSTER AIRCRAFT Ltd. Nov. 8, 1963 [Aug. 9, 1962], No.30589/62. Heading G3R. A D. C. load is supplied from an A. C. source by way of a transformer, a rectifier and a tank circuit which has its capacitor charged under the control of a switching circuit in dependence upon output voltage variations, whereby the output voltage is maintained at a constant value. As shown, duplicated channels 11 and 12 supply separate outputs. For channel 12 the D.C. output voltage is taken across the capacitor 17 of a tank circuit 18 which also includes an inductor 26 and a diode 27. The charging current for the tank circuit is derived from an input transformer 16 via a full wave rectifier 20 under the control of switching transistors 28. A fraction of the output voltage is fed back on lines 22 to a comparator 23 for comparison with a reference voltage derived from a Zener diode 24, and the output from the comparator 23 is applied over a transistor 40 to a Schmidt trigger circuit 25 which in turn delivers an output signal which is applied via transistors 43 as a controlling bias to the switching transistors 28. A voltage divider 33, 34, 35 in the feedback circuit enables the output voltage to be adjusted to a desired value.

Filed: 1952-12-04
Abstract: 717,654. Filtering liquids. JALKANEN, M. J. Dec. 4, 1952, No. 30796/52. Class 46 Apparatus for separating solid particles from a liquid suspension thereof comprises a container 1 Fig. 1, partitioned by a filter screen 13 and a relatively rotating doctor arm 11 having means, e.g. a blade 16 on its leading edge, for mechanically removing particles from the screen, a duct 25, Fig. 4, through which stock suspension is fed on to the screen 13 and a duct 26 whereby filtrate having traversed the filter screen in the reverse direction is discharged ; the reverse flow serving to dislodge the residue of particles left by the scraper blade 16. The ducts 25, 26 together with a duct 27 supplied with liquid at high pressure lead to sector-like chambers 22, 21, 18 respectively, Fig. 2, formed within the arm 11 and open to the screen 13. The high pressure liquid issues from the chamber 18 through slots 19, Fig. 6, to assist the action of the blade 16; direct flow between the chambers 18, 21 being prevented by an adjustable packing flange 17. The arm 11 together with a paddle 4, agitators 5 and a blade 6 are secured to a rotatable shaft 3 and the separated particles are washed with liquid supplied through ducts 9, 10 before the suspension so formed is discharged through an opening 7. In a modification the arm is so shaped that its relative motion with the screen causes a motion in the liquid at the leading edge of the arm tending to remove solid particles from the screen. The arm may remain stationary and the screen rotate and a plurality of arms and screens may be provided.

Abstract: 893,046. Controlled electric supply systems. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Oct. 1, 1958 [Oct. 4, 1957], No. 31178/57. Class 38 (4). The current supplied to a load from an A.C. source is controlled by connecting a reactance permanently in series with the source and intermittently short-circuiting the load. In one embodiment the load is the cathode of an electron-bombardment furnace or an ionization gauge and the cathode current is controlled so as to keep the space current constant; in a second embodiment, the load is the filament of a lamp, the light output of which is maintained constant. In the first embodiment, Fig. 2, the cathode of the furnace or gauge D is supplied from secondary winding N2 of a transformer, the primary N1 of which is connected to the supply through a capacitor X. The space current of the device D is measured by the voltage across resistor-R which is compared with a reference voltage B, and any error is amplified at A to provide a D.C. control signal. This is added to a phase-shifted A.C. signal derived from a resistance-capacity bridge energized from a secondary winding N4, and.. the resultant signal controls the firing period of a pair of thyratrons V 1 , V 2  connected to short-circuit a further secondary winding N3. In a modification, Fig. 1 (not shown), the winding N2 supplies an unspecified load and the thyratron control voltage is obtained from an unspecified source. It is stated that the transformer may be omitted. In the second embodiment, Fig. 3, the output of a lamp L energized from the winding N2 is detected by a photo-cell P. A voltage proportional to the current passed by the cell is compared with a reference voltage B and any error signal, amplified at A, is added to the phase-shifted unidirectional pulses derived from winding N4, capacitor C and rectifier D3 to control the conductivity of a transistor T1, which conducts on alternate half-cycles through rectifiers D1, D2 to short-circuit the winding N3.
