Abstract: A method and apparatus for playback of a data recording disc which contains a CD area in which a signal such as an audio signal is recorded in digital form and a video area in which a FM-modulated video signal is recorded with a digital audio signal superimposed thereon. The position of a data detection point of a pickup is monitored, and the equalization and amplifier gain of components of a digital demodulation system are automatically changed in accordance with playback being executed of the CD area or the video area, so that a single demodulation system is used for woth digital signals from the CD area and digital signals from the video area. In addition, the frequency characteristics of components in servo systems which control the spindle motor, pickup carriage, etc. of the apparatus are automatically changed over for CD area and video area playback respectively, to provide stable servo control in spite of the high speed of rotation during video data playback.

Abstract: An ophthalmic device (1) includes a base (5), a suction ring (3) connected to the base (5) to secure the device (1) to the eye (E) of a patient, and a support piece (13) carrying a pair of securely ganged cutting blades (7,9) having cutting edges (47) oriented at an angle with respect to one another. The support piece (13) can be raised and lowered with respect to the eye surface, and rotated around the base (5) to simultaneously form two incisions along a path on the eye. The device (1) includes a mechanism for progressively advancing the two cutting blades (7,9) together in the support piece (13), while maintaining a constant angular cutting edge relative orientation, to a position in which the cutting points (49) of the two cutting blades (7,9) are touching, and can thus be used to form an annular wedge-like cut of eye tissue in the treatment of refractive errors. In alternative embodiments, laser or electrosurgical knives may be used instead of cutting blades.

Abstract: A disposable pricker has a body (1,2) lance (4) spring (3) and cap (13) integrally moulded in plastics, the cap being subsequently separable. The lance tip (5) is a needle embedded in the moulding and relatively inaccessible within the body. Formations (17) within the cap compress the spring (3) as the cap is fitted until they are flexed aside by co-operation with abutments (7) within the body. The lance (4) is released and shoots forward for the tip (5) momentarily to project proud of the cap (13). The latter is made captive to the lance (4) during this movement and cannot be removed to repeat the operation. The lance tip (5) thus remains concealed within the cap (13). In another capless version, squeezing the body (31) wedges the lance (36) back until it escapes and is shot forward by a spring (38). On recovery within the body, the lance is blocked from reverting to the position where it can be re-actuated.

Abstract: The invention relates to a method for orientating a second pattern (7a), deriving from a first pattern (6a) formed on a stencil (6), in relation to print material (7) so that the second pattern (7a) will have a pre-determined position in relation to the print material (7). The second pattern (7a) is formed by, in a printing position, passing coating substance through the first pattern (6a) and onto the print material, for instance with the aid of a squeegee in a silk screen printer. 
     It is proposed;
     a) That the position of the print material in relation to a reference value, e.g. the printer chassis, is established in a first registered position (A), a material feed position, and the resultant measurement values stored;   b) That the print material is moved to a second registered position, a printing position or the receipt of the second pattern;   c) That the material (7) printed with the second pattern (7a) according to "b" above is moved back to the first registered position (A) and the position of the printed second pattern (7a) in relation to said reference value is established and the resultant measurement values stored;   d) That in response to an established discrepancy between the actual position of the pattern, obtained by the transfer according to "b" above and its pre-determined position, the stencil frame carrying the first pattern, and/or the print material and/or the printing table or the first registered position (A) is displaced to an extent and in a direction such as to minimise the established discrepancy;     e) That each subsequent print material registered in a similar manner in the first (A) and the second (B) position is printed in the second position (B) with a second pattern (7a) applied with minimised discrepancy.
