Title: Apparatus for reading records optically
IPC: G11B7/13
Filed: 1976-02-25
Abstract: 1533888 Automatic control of focus and position PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 25 Feb 1976 [28 Feb 1975] 07415/76 Heading G3R In optical playback apparatus, parallel tracks are read by at least two detectors disposed on the same side of a plane passing through the optical axis of the apparatus and the track to be read, and within the "far field" of the track i.e. disposed so that different diffraction orders can be distinguished. The apparatus also includes tracking and focus error corrections for the optical system. In the embodiment, for optically reading video data points 3 (e.g. pits) in a spiral or concentric track of a disc 1, a laser beam passes via mirror 9 and objective lens 11 to the disc. After transmission through, or reflection from, the data point 3, the beam which is modulated according to the information on the disc passes via lens 11, mirrors 8 and 9 to detectors 12, 13 and 14. The detector 12 is used to extract the video signal Si, and the detectors 13, 14 are used to sense interference lines of the modulated beam, the data points 3 acting as a diffraction grating. The period of the interference lines is determined by the focusing of the beam on data points 3, and the phase determined by the position of the beam relative to the data track i.e. centering of the beam. The outputs of detectors 13, 14 are summed to form a centering control signal Sr that varies the movement of mirror 9, and the outputs are differenced to form a focusing control signal Sf that varies the position of lens 11. The mirror 9 and lens 11 are moved until their respective control signals Sr, Sf are zero, preferably utilizing the centering control first. Up to four rectangular or triangular detectors may be used in the focusing and centering controls and these detectors are placed remote from the information detector 12.

Movable-abutment type.-Relates to a pump in which the casing k and the rotor h both revolve, the former being adapted to receive a band by which it is driven. The rotor is carried at the same time to gyrate within the casing by eccentrics d carried by fixed shafts c, which are hollow and form inlet and outlet passages. These passages lead to chambers f in the rotor separated by a partition g and communicating with the pump chamber through ports o, o in the rotor. The casing consists of a peripheral part and side plates i. The movement of the rotor within the casing is controlled by an oscillating block m having a tongue l, which slides in a slot n in the rotor, and which also separates the inlet and outlet ports o, o. In one modinoation, the tongue l is formed in the rotor, and the slot in which it slides is formed in the block m. In another modification, which in this respect is a simple inversion of the form shown, the rotor carries the block m, and the tongue slides in a slot in the casing. The rotor may be driven by a single eccentric.

Abstract: 550,076. Preserving vegetables. BARKER, J., ALLEN, R. J. L., and MAPSON, L. W. June 26, 1941 No. 8046. [Class 49] The scalding of vegetables, which are to be preserved as by drying, is effected in the presence of a small proportion of sulphur dioxide or a sulphite. A dilute solution of sulphur dioxide or a sulphite may be made in the scalding water or the vegetables may be treated with a stronger solution or with sulphur dioxide gas and then scalded with water or steam. The preferred strength of the scalding solution is for cabbages and carrots 2.2 parts, and for carrots 0.5 parts, of crystalline sodium sulphite per 1,000 parts of water, or cabbages may be soaked in a 2 per cent. solution of the salt for about 5 minutes before scalding in steam. The vegetables are reduced in size before treatment and may be mixed with meat, the mixture being subsequently dried for the preparation of soups. The same scalding water may be used for successive batches of vegetables, about one quarter of the original quantity of sulphur dioxide or sulphite being added for each batch.

In a tyre deflation indicator of the kind comprising a support member 10 attached to the vehicle with a feeler member 14 depending therefrom to contact either the ground, or the bulged tyre sidewall, on tyre deflation, and to be moved thereby to close contacts 19, 24 on the support 10 and feeler 14 respectively to operate a warning signal, the feeler member 14 has a feeler element 12 attached thereto to be adjustable both longitudinally for height, and angularly about a horizontal axis at right angles to the tyre axis, with respect to the support 10 for selective operation either by the ground or by the tyre. As shown, the support 10 comprises an apertured strip for selective positional attachment to the vehicle and the feeler member 14 comprises a thin plate bolted to one face of the support 10 and backed by a spring strip 16. An additional spring strip 17 is bolted to the opposite face of the support 10 and carries the insulated contact 19 which is connected by a terminal 20 on a lead (not shown) to an earth return warning lamp. The strip 17 is spaced from the plate 14 by a rubber spacer 18, and the contacts 24 and 19 and the terminal 20 are protected by rubber housings 22, 23 respectively. A plate 25, having holes 30 arranged on an arc for selective engagement with a projecting rivet 31 on the plate 14, is clamped in the desired angular position by a hexagon-headed bolt 26, the head 28 of which is positively located in a complementarily-shaped recess 27 in the plate 25. The bolt passes through the plate 14 for engagement by a nut 32 and has a transverse hole 29 through its head 28 to receive slidably the shank of the feeler element 12, tightening of the nut 32 serving to clamp the element 12 against the plate 25 and to hold both in their set positions relative to each other and the plate 14. Angular adjustment of the element 12, which has a bulbous operative end 13, may be effected either by engagement of a different hole 30 in the plate 25 over the rivet 31, or by engagement of the bolt head 28 in a different angular position in the plate recess 27.
