Abstract: A needle type probe having a displacement surface acting as a bridge which extends across the aperture into the lumen of the needle. The displacement surface defines two approximately equal lateral openings on either side of the bridge and acts to displace and stretch the skin about the needle shank. A holder for the needle type probe is provided which comprises a sleeve which is pushed over the shank of the needle with a force fit, the sleeve having a stopper portion at the end towards the needle point and a holder plate rotatably mounted on the sleeve by means of a collar which is fit over the sleeve. The stopper portion and the front edge of the holder plate collar each have a serrated surface for selectively restricting rotational movement of the collar relative to the sleeve and needle shank. There is further provided a method for making a needle type probe of the instant invention wherein a point wise force is exerted on a tubular needle material at its front edge and the end of the tube is collapsed onto itself until contact is made between radially opposite inner portions of the inner surface of the needle shank. The shank is then ground rearwardly from the contact point to form a bridge extending from the needle point rearwardly with openings on either side of the bridge.

Title: Method and apparatus for conveying information signals
IPC: H04N19/593
Filed: 1986-12-19
Granted: 1991-10-23
Abstract: Video signals from a source (10) are digitised and applied to a source coder (15) which segregates the signals into four channels (CH1 to CH4) of progressively less visual significance. CH1 carries basic picture information at a relatively low resolution. CH2 to CH4 carry differential information at progressively higher resolutions. The four channels signals are applied to respective coders (16) and the digital outputs are combined in a matrix (18) with voltage levels falling off as visual significance decreases. Received signals, transmitted say by way of a satellite (22), are applied to a first, high level decoder (32) which extracts the digital waveform for CH1 as DCH1. This is recoded and subtracted from the input to provide a signal to a decoder (42) which recovers CH2 as DCH2, and so on. DCH1 to DCH4 are applied to a source decoder complementary to the coder (14) to recover the source signal. Low significant channels can be omitted at the transmitter, or not be recovered at the receiver to adapt to the prevailing signal to noise performance.

Abstract: On a étudié l'amélioration de la force coercitive d'aimants frittés et magnétiquement anisotropes à base de Fe-B-R, en augmentant la teneur en B, en ajoutant au matériau de base une faible quantité d'Al, Si, Cu, Cr, Ni et Mn, servant à augmenter la force coercitive, et en éliminant du matériau les impuretés nuisibles telles que P, S et Sb. Ledit matériau a été réduit en poussière par les procédés habituels de fusion, coulée, concassage ou réduction directe. Cette poudre a été soumise à orientation dans un champ magnétique et ensuite compactée, frittée et soumise à un traitement thermique. Ce procédé permet d'obtenir des aimants permanents frittés à base de F-B-R présentant un produit énergétique maximum supérieur à 20 MGOe et une force coercitive supérieure à 15 kOe.

Abstract: Apparatus and method of synchronizing the component signals of a multi-component augmented television signal between its generation reception are disclosed. The disclosed apparatus includes circuitry which generates a training signal that indicates the position of the first pixel in each horizontal line interval of the video signal. This training signal is inserted into one horizontal line interval of the active video signal for transmission. The receiver includes circuitry which separates the training signal and derives a timing signal from it. The timing signal is used to define the pixel positions of various decoded components of the received video signal to facilitate their combination. The timing signal is also used to align the color subcarrier signal and to generate other carrier and subcarrier signals used in the decoding process. Two training signals are disclosed: a pseudo-random noise sequence and a time-reversed, all-pass filtered, raised-cosine 2T pulse.
