Inventor: PRABHU VASANT KRISHNA
IPC: H04B1/68

Abstract: Système radio mobile à bande latérale unique (SSB) à saut de fréquence mis en oeuvre en sautant la fréquence porteuse d'un signal d'entrée (s(t)) toutes les tau secondes. Le saut est commandé par une séquence de sauts de fréquence porteuse (fi(t)) produite par un générateur de sauts de fréquence porteuse (16, 24). Lorsqu'elle est utilisée dans un émetteur SSB à sauts de fréquence (10), la séquence porteuse permet de moduler le signal d'entrée, en le faisant "sauter" à une différente fréquence porteuse toutes les tau secondes. Le récepteur SSB à sauts de fréquence porteuse utilise la même séquence porteuse utilisée par l'émetteur pour démoduler le signal SSB à sauts de fréquence porteuse transmis, retrouvant ainsi le signal original de bande latérale unique (s(t)). Grâce au saut de fréquence du signal porteur d'un signal SSB, la présente invention permet de réduire les effets d'interférence entre les canaux et de fading dépendants de la fréquence propres aux systèmes radio mobiles cellulaires SSB de l'art antérieur.

Abstract: Both the leading and trailing ends of the respective yarns introduced to and removed from active knitting position are cut to a uniform length on the inside of the sock when forming solid color patterned areas in the sock. The cutting of all yam ends to a uniform length inside of the sock enables the operator to easily evert and inspect the inside of the socks as they are removed from the knitting machine and eliminates the usual time consuming operation of cutting the yarn ends after the sock is knit. The cutting and clamping apparatus includes a pair of suction tubes (44,44') supported within the needle cylinder (10) and yam clamping members (51, 51') carried by the lower ends (45, 45') of the suction tubes (44,44'). A hot wire cutter (60) is positioned between the needle cylinder (10) and the clamping members (51, 51 and yam lifting members (75,75') are provided for engaging and raising a yarn moved to inactive position into engagement with the hot wire cutter (60).

Abstract: A high voltage connector is provided for interconnecting a power cable to an apparatus such as a transformer. The cable is securely coupled to the connector, which is then mounted on to the transformer bushing. The bushing and cable electrical contacts inside the connector are spaced apart, and electrical connection is achieved therebetween by inserting a continuity plug into a socket of the connector. Electrical isolation between the cable and transfoimer may be effected without physically moving either piece of equipment, by removing the continuity plug and replacing it with another plug that introduces sufficient electrical insulation between the equipment contacts to allow operating and test voltages to be applied to one of the cable and transformer without flashover occurring to the other of said pieces of equipment. Other interchangeable plugs may provide earthing for a selected one of the pieces of .equipment, also without requiring physical movement of the equipment.

Abstract: A multiple transistor, preferably of the N-P-N type with a common emitter, has the emitter implemented as a highly doped bottom diffusion (12) in a Psubstrate (11) or as a highly doped N substrate (33). The base consists of a P-doped bottom diffusion (13) under the epitaxial collector layer (15) and the separate collector connections are made as shallow contact diffusions in the collector layer (15). The collector region is limited by an inner ring (17A,17B) of the same conductive type as the base layer (13) and makes contact with the latter. An outer ring (18,18A) of the same conductive type (N) as the emitter layer makes contact with this and is also utilized for contacting the emitter layer when this layer consists of a bottom diffusion (12).

Abstract: A battery economising circuit for use with one or more operating circuits, for example a part or parts of a radio circuit, in which battery economising circuit an opposed current mirror type of current reference circuit (18) determines entirely the current consumed by the operating circuit (10). A control circuit (22) is connected to a point in the reference circuit (18) from which current can be extracted. The control circuit (22) in response to an OFF signal causes a portion of the current in the reference circuit (18) to be diverted so that the reference circuit (18) cannot sustain its normal ON-state and in response thereto assumes its OFF-state in which the operating and control circuits (10, 22) do not take current. The control circuit (22) further includes means whereby current can be injected into the current reference circuit (18) to cause it to assume its ON state and in consequence the operating circuit (10) takes current. 
     In the case of there being several current reference circuits (18, 18') and associated control circuits (22, 22'), the inputs (24, 24') of the control circuits (22, 22') are all connected to a common signalling bus (26).

Abstract: A video signal processing apparatus for use in a video tape recorder of the PAL system obtains a composite video signal without causing a vertical colour shift on a display screen which would normally be caused by a time difference between a chrominance signal and a luminance signal. The apparatus comprises a 1H delay circuit (1) for delaying an input luminance signal by one horizontal synchronizing period (1H), an operational circuit (12), a 2H comb filter (10) that passes an input chrominance signal, and an adder circuit (5) for adding an output signal of the operational circuit (12) and an output signal of the 2H comb filter (10) thereby to obtain the composite video signal. The operational circuit (12) allows an output signal of the 1H delay circuit to pass therethrough when a difference in level between the input luminance signal and the output signal of the 1H delay circuit is large, and, when the difference is small, outputs a sum of the two signals.

Abstract: It is decribed a method for the non-destructive test of a joint obtained by electric spot welding of two sheets, substantially of the same material, joined together in a local zone with the formation of a core, its structure having a thermal diffusivity substantially different from the thermal diffusivity of the material of the two sheets before welding, a result which is obtained only when the welding is of a good quality. 
     This purpose is attained by a device whose main characteristic is to comprise an electrode able to supply a source of heat and a detector which are fitted to be placed on two conveniently chosen points on the surface of the two welded sheets, a generator feeding the electrode and an amplifier having an input connected to said detector and an output connected by a A/D converter to a computer able to process the signal and to give an indication of the welding quality on the basis of the measured value of the thermal diffusivity.

Abstract: Une cage pour la mise bas tient compte non seulement mieux qu'auparavant mais pleinement des besoins des animaux (truie et porcelets) avant, pendant et immédiatement après la mise bas (environ durant 8 jours). Cette cage de mise bas est équipée de tous les détails techniques orientés exactement sur les besoins des porcelets durant la première semaine de vie. La cage de mise bas classique pour toute la période d'allaitement devient maintenant une "station spéciale de mise bas" en tant que station de couches pour ainsi dire, pour les 8 premiers jours d'existence, c'est-à-dire pour la phase comportant des risques. A la suite de cette phase, les porcelets peuvent être logés avec la truie dans une cage de mise bas classique (de préférence désignée cage d'élevage de porcelets). La station de mise bas est ainsi de nouveau libre après 5-10 jours et est déjà disponible pour la prochaine truie portante. Une exploitation qui, jusqu'à présent, devait avoir 10 cages de mise bas pour une période d'allaitement de cinq semaines, devrait remplacer deux cages de mise bas par des "stations de mise bas" et s'en sortirait ainsi complètement. Les porcelets sont bloqués dans le nid chaud (3) chaque fois que la truie (38) se lève et reçoivent toujours automatiquement de l'eau fraîche ou une solution électrolytique ou du lait dans l'auge. Celle-ci est continuellement nettoyée automatiquement avant un nouveau remplissage. Toute la station ainsi que la truie sont lavées et désinfectées automatiquement.
