Title: Dithered center tracking system
Inventor: CANINO LAWRENCE S
IPC: G11B21/10
Filed: 1979-11-08
Granted: 1982-09-21
Abstract: DITHERED CENTER TRACKING SYSTEM     ABSTRACT OF THE DISCLOSURE     A servo control system for maintaining an information detection device,  such as a light beam, centered on a moving information track, such as a spiral  recording track on a video disc.   The system of the  invention includes a dither signal genera-tor,  a bandpass filter  for deriving an  intermediate signal  indicative of the effect of dither on the detected signal derived from the information track, and switching circuitry for deriving an error signal from the intermediate signal and the polarity of the dither signal.   In one embodiment of the  invention, the switching circuitry includes an inverter, and a switch for  selecting  either  the  intermediate  signal  or  the inverted  intermediate  signal, in accordance with the polarity of the dither signal.  The error signal thus derived is low-pass filtered and has a positive value when the center position of the beam moves to one side of the track, and a negative value when the center position of the beam moves to the other side.   In an  alternate  embodiment,  a  pulse generator  provides two trains of pulses occurring at the positive and negative peaks of the dither signal, respectively, and  the pulse  trains are employed to control two sample-to-bold circuits, respectively supplied with the intermediate signal and its inverse.

Abstract: ABSTRACT OF THE DISCLOSURE The invention is a process for producing a polymer or copolymer of an alpha-olefin by continuously polymerizing or copolymerizing the alpha-olefin and optionally up to 5 mole % of a diolefin in the presence of a catalyst. This catalyst is composed of (A) a solid magnesium compound obtained by react-ing (i) an adduct between a magnesium halide and an electron donor, with (ii) an organometallic compound of a metal of Groups I to III of Mendelejeff's Periodic Table, (B) a liquid transition metal compound of a metal selected from titanium and vanadium and (C) an organoaluminum compound.  During the process catalyst component (B) is fed to the polymerization or copolymerization zone separately from components (A) and (C).  The products of the process are polymers or copolymers of alpha-olefins having a narrow molecular weight distribution.

Abstract: ABSTRACT OF THE DISCLOSURE         Infectivity and replication of influenza viruses in successive numbers of cells of the same liquid cell culture is assured by including a protein hydrolyzing enzyme in the culture during virus incubation.  Technique overcomes "one-step growth cycle" of virus and allows commercial influenza vaccine pro-duction from liquid cell cultures instead of from more costly embryonated chicken eggs.  Resulting vaccine is thus substanti-ally free of egg proteins.

Abstract: A b s t r a c t The clamping device of the anti-slip device comprises: a resilient pull or tensioning member (12) extending peripherally of the vehicle wheel; a clamping wire also extending peripherally; two locking members (18, 19); and two release members (22, 23).   The pull member (12) has both its ends secured to a rectangular frame (25) which extends around the locking members (18, 19) and the release members (22, 23).   The clamping wire (17) is secured relatively to the pull member (12) in a position opposite the frame (25) and has both its free ends (17a, 17b) extending through the locking members (18, 19) and release members (22, 23, in the frame (25).   The locking member (18) and associated release member (22) are associated with the wire end (17a) whereas the locking member (19) and release member (23) are associated with wire end (17b).   With the anti-slip device fitted and with the release members (22, 23) in the locking position, the locking members (18, 14) allow the clamping device to move relatively to the wire ends (17a, 17b) only in the sense of a shortening of the effective length of the wire (17).   With the release members (22, 23) - and therefore the locking members (18, 19) -in the release position, the wire ends (17a, 17b) can move relatively to the clamping device in the opposite direction.    The anti-slip device can be fitted readily; securing is reliable and take-up is automatic.
