Title: Appratus for reading a disc-shaped record carrier containing signals coded in optical form
IPC: G11B7/00
Filed: 1973-03-26
Abstract: 1429882 Automatic control of position PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 26 March 1973 [29 March 1972] 14453/73 Headings G3N and G3R In apparatus for reading a video disc 1 and comprising an optical head 4 which includes a light source 7'and a reading head 13, proper alignment of the scanned point a with the desired track of the disc being ensured by a slow, coarse control loop which adjusts the radial position of the head 4 and a fast, fine control loop which adjusts the angle of a mirror 12 pivoted at 18, a switching means S'is provided for opening the fine control  loop, allowing injection of a control signal from c to shift the mirror angle by an amount corresponding to e.g. one track spacing, and then reclosing the fine loop. The video information may thus be presented for a variable length of time allowing selection of slow or fast motion pictures or holding as a still picture. A still picture may be  accompanied by a continuous audio programme by multi-plexing the recorded audio signal at different carrier frequencies for successive revolutions of the disc, and adding a monitor signal so that the appropriate carrier frequencies are selected in turn by the reading apparatus. As shown the head 13 includes an information reading detector 14 and a positional detector 15 in the form of a grating. A positional error signal is fed via amplifier V 1  to a Piezo-electric transducer 19 to adjust the mirror angle, and an additional fluid amplifier may be used to increase the effective rotation. Deviation of the mirror from a central position is used as the coarse control signal and may be derived directly from the mirror or indirectly from the amplifier V 1 . The coarse control signal is fed via amplifier V 2  to a motor M2 driving a worm 5 and rack 6 to move the head 4. The coarse control may alternatively operate intermittently when the mirror angle exceeds a limiting value. The displacement of the mirror 12 may be produced electromagnetically Fig. 3 (not shown), and the mirror may be replaced by a transmissive element. Light reflected from rather than transmitted through the disc 1 may be used Fig. 2 (not shown). The switching means S and its actuating unit A are a circuit using two complementary F.E.T.s(T 1 , T 2 ) Fig. 4. (not shown). The switch controlling pulses (U 1 ) and  the injected control signal (U 2 ) are derived from frame pulses of the video signal.

Title: Manipulating a liquid medium for the purpose of separating materials, segregating materials or contacting materials
IPC: B03B5/04
Filed: 1934-05-15
Abstract: A liquid which has particles of another substance dispersed therein is confined on all sides and on the bottom in a container which is reciprocated along a line having a vertical component and a substantial horizontal component at such a rate that in a down-stroke the liquid descends through a greater distance than that in which it would fall in the same time due to the action of gravity alone.  The liquid is thereby vigorously arrested at the end of each down-stroke and an upwardly directed force is exerted on the particles therein. The process may be applied to segregating particles of an elastic liquid such as oil from a mixture such as industrial waste consisting of grease or oil dispersed in water, the oil or grease being segregated as a floating mass on the water.ALSO:A liquid which has particles of another substance dispersed therein is confined on all sides and on the bottom in a container which is reciprocated along a line having a vertical component and a substantial horizontal component at such a rate that in a down-stroke the liquid descends through a greater distance than that through which it would fall in the same time due to the action of gravity alone.  The liquid is thereby vigorously arrested at the end of each down-stroke and an upwardly directed force is exerted on the particles therein.  The process may be applied to separating solids from liquids, e.g. dewatering slimes, sewage, &c.  The vibration causes solid particles to move through the liquid and up the sloping side of the container and particles of substances such as oil or grease are segregated in a mass floating on the surface of the liquid.

Title: Improvements relating to the manufacture of stannic acid or oxides of tin
IPC: C01G19/02
Filed: 1926-06-11
Abstract: 263,034. Harris, H., (Heberlein, K. B.). June 11, 1926. Tin oxides, particularly such as contain small quantities of arsenic or antimony, are purified by heating in solid form with a small percentage of an alkali carbonate, preferably sodium or potassium carbonate, or of an alkali mineral acid salt, e.g. sodium sulphate, proportioned to the percentage of impurities to be removed, and then leaching to remove the soluble impurities, pureferably after grinding the heated mass with water. The mixture is preferably heated to at least 1000‹ C., and the heating with alkali carbonate and leaching may be repeated, if necessary. If the impure oxide, already contains an alkali carbonate or an alkali mineral acid salt by reason of its origin, the addition of these purifying agents may be unnecessary. Suitable proportions of carbonates to be added for each part of arsenic or antimony are 2.7 parts of sodium carbonate or 4 parts of potassium carbonate. The invention is particularly applicable to the treatment of stannic acid derived from alkali stannate solutions by treatment with acids, as, for example, that obtained as a by-product in treating impure molten lead for the removal of tin, arsenic and antimony as described in Specification 213,638.

Title: Improvements in and relating to percussion fuses
IPC: F42C15/22
Filed: 1925-06-09
Abstract: 235,240. Pantoflicek, B. June 9, 1924, [Convention date]. Projectile fuzes. - Relates to fuzes which act regardless of the manner in which the shell strikes, and which include a mass capable of rotation in the same direction as the shell, the cessation of rotation of the shell on impact causing the mass to continue its rotation by momentum to ignite the cap directly or indirectly. According to the invention, a rotary mass in the form of a weighted ring or a number of balls causes the release of a separate member interposed between the mass and the member which effects ignition. In the form shown in Fig. 1, a ball-bearing flywheel 3 is driven at the same speed as the shell by radially movable pins 9, 6. The pins 6, which are normally retained by a spring ring 8, are released by centrifugal force during flight. The pins 9 then drive the flywheel and retain the striker 10 until the rotation of the shell is checked. when the flywheel continues its rotation. The pins 9 can then escape radially through apertures in the ring 3 to release the striker. In a modification, Fig. 4, balls 16 are driven by fixed pins 19, the sliding pins 18 being set back by inertia on discharge. When the rotation of the shell is checked, the balls 16 move in the direction of the arrow to release other balls 20 which retain the striker. In a further modification, balls driven by fixed vanes, on over-running, operate to rotate a sleeve with moving vanes, to bring the balls retaining the striker into the release position.
