Patent EP-0269094-B1 (EP)
IPC: H04N9/00
Filed: 1987-11-25
Granted: 1993-07-14
Abstract: In a TV answer back system where many receiver stations communicate with a TV transmitter station by means of rf pulses generated by rf oscillators at the receiver station, the requirement for keeping all oscillators on frequency is achieved without crystal control by automatically controlling the rf oscillator frequency using synchronization signals carried in the video signal received from the TV studio. By this invention it has been possible to control the frequency of multiple megahertz oscillator as accurately as desired from relatively low frequency synchronizing signals such as the vertical and horizontal video sync pulses. Thus an oscillations counter is gated for a very accurate time period by the sync pulses, and the oscillation count is compared with a datum count representing the desired oscillation frequency. The requirement to prevent receiver stations from answering with rf pulses in response to queries contained in home video recordings of previously broadcast signals is achieved by encoding broadcast time on all query containing TV transmissions, and by comparing at receiver stations broadcast time information from received signal with time from a local battery backed clock contained at each receiver station, thus discrimination of video recordings is possible by comparing received video broadcast time with local time.
Patent EP-0270479-B1 (EP)
IPC: G02B6/44
Filed: 1987-09-30
Granted: 1992-05-06
Abstract: A splice cassette housing for optical waveguides has to be brought from an installation position, e.g. a socket-type housing, to a splice position. The incoming and outgoing optical waveguide cables fed with known splice cassette housings along the longitudinal sidewalls are disadvantageous for the free mobility of the splice cassette housing. In order to achieve a high degree of freedom in the mobility of the splice cassette housing, the incoming and outgoing optical waveguide cables 8 and 9 are usually fed separately from each other to the splice cassette housing in a common axis within a flexible hose. Further, a groove-type guide channel 11 in the shape of a member "9" is provided in the bottom 6 of the housing for a change in direction of one of the optical waveguide cables by 180 DEG , in order to be able to feed the individual optical waveguides again from opposed directions to the splice position. The splice cassette housing is suitable for applications especially in cable-terminal boxes, but also in cable distributors and the like for glass-fiber cables.

Title: Procede de reformatage de signaux de television couleur
IPC: H04N11/02
Filed: 1987-05-28
Granted: 1992-08-19
Abstract: Procédé et appareil de reformatage de signaux de télévision couleur MAC dans le but de réduire la largeur de bande. Les composantes de chrominance et de luminance sont disposés en série sur une base ligne par ligne, la composante de chrominance n'étant pas comprimée ou l'étant de manière minime. Le rapport d'aspect est réduit du rapport d'aspect standard au moyen d'une porte (5) qui tronque les bords et envoie les signaux MAC dans les mémoires (10, 11) à des fins d'expansion temporelles ultérieures. Etant donnée qu'un tube d'image de télévision normal effectue un surbalayage, les bords de l'image ne sont jamais affichés et n'ont pas besoin d'être transmises ou enregistrés. Le signal reformaté peut-être rendu compatible avec un signal composite standard par une simple expansion (22) et modulation de la chrominance qui est ajoutée à la luminance (25) le signal compatible possède un temps vidéo actif plus court et un rapport d'aspect plus petit.

Inventor: NIESCHWITZ PAUL-JOSEF DR
IPC: G01B11/24
Filed: 1989-10-14
Granted: 1992-05-20
Abstract: A process for determining the geometry of an object (10) in a forging press is specified, it being the case that for the purpose of being processed the object in the forging press is displaced for a processing pass and rotated about the longitudinal axis in a predetermined fashion. In this process, the surface of the object (10) is continuously scanned over the circumference in a manner known per se in planes perpendicular to the direction of displacement of the object. Thereafter, the scanned data are transmitted to a computer programmed in advance, and subsequently converted in the computer with the aid of a program based on the volume constancy conditions in such a way that the actual geometry of the object (10) is acquired. The acquired actual geometry is processed in the computer so as to introduce a further transformation step with predetermined programmed forging parameters. A device for carrying out the process consists of a carrier, which is constructed as a ring (13), is arranged in the vicinity of the processing region of the object (10), and is attached to a sensor (15), rotating about the object at a defined rate. Installed on the inner surface (14) of the ring (13) at two or more oppositely located points are beam transmitters (11) and beam receivers (12) arranged adjacently in each case.

In an injection procedure, the end wall (2) of the cylindrical hollow body (1) is pierced by the spike (6), so that, in the event of an attempt to draw up a disposable syringe which has already been used, the space in the syringe barrel would draw in air through the aperture formed by the spike (6) in the end wall (2) of the cylindrical hollow body (1).
