Title: Arc welding appts. with a transformerless power supply unit
Inventor: SCHMIDT KLAUS-P
IPC: H02M3/337
Filed: 1994-05-09
Abstract: The arc welding appts. is provided with a preferably transformerless power supply unit (11) producing direct current, an inverse rectifier (12), a step-down voltage transformer (13), and a rectifier (14) supplying direct current to a welding circuit (17) including the welding electrode (15).

Title: Device for exchanging a cannula
Inventor: NOBLES ANTHONY A
IPC: A61M25/01
Filed: 1994-05-25
Abstract: The invention describes a method and a device for removal of an existing cannula from a patient (16) and for insertion of a replacement cannula (54) in the patient through the same channel, a guide rod (20) being used which maintains the channel.

Title: Constant uninterrupted lighting of model railway vehicles
Inventor: DAHL CLAUS DIPL ING
IPC: A63H19/20
Filed: 1994-05-30
Abstract: The lighting systems of model railway vehicles (interior lighting, lighting for the tips of trains and the ends of trains, etc.) are supplied with electrical energy from the driving voltage. Deficiencies of this method are a) the dependence of the brightness of the lighting system on the driving voltage and b) fluctuations in brightness caused by unreliable power drain caused by technical and environmental influences. The invention uses an accumulator battery which is buffered with a controlled power supply component in order to supply the lighting system of a vehicle with power. The power supply component (3) which is fed from the driving voltage (7) virtually assumes the function of adapting the respective type and direction of voltage, adjusting the driving voltage to the value of the constant voltage (8) and thirdly charging the accumulator battery (4) in a monitored way. The constant voltage (8) supplies the load(s) (5) without interruption in the event of contact faults and the failure of the driving voltage and ensures constant brightness. A manually actuated or remote-actuated switching means permits switching on and switching off, enables capacity to be increased, loads in other vehicles to be supplied with power and other electrical/electronic model vehicle functions to be performed. The constant and uninterrupted power supply in model railway vehicles is suitable for all rated sizes of model railways and all power supply systems. <IMAGE>

Title: Resetting device for a travel direction indicator
Inventor: NORO YOSHIMI
IPC: B60Q1/42
Filed: 1994-09-28
Abstract: A resetting device of a travel direction indicator has a body to which a carrier is attached, to which a control lever and a backplate are attached. Balls are arranged in the carrier and, if the balls are in engagement with a moderation element, the carrier can be held in its right-hand turn position. A locking latch is also arranged in the body and, if the locking latch is turned, the surface of the backplate which is to be pressed is pressed by the pressing surface of the locking latch so that the carrier is turned into its neutral position and returned. In this case, the locking latch comprises an inclined pressing surface and, in the event of the locking latch being turned, the contact section between the pressing surface of the locking latch and the surface of the backplate to be pressed is moved from a point  alpha in the locking latch to a point  alpha '.

Title: Skid vehicle for ice surfaces
Inventor: HUEGELMEYER BERND
IPC: B62M27/00
Filed: 1986-12-23
Abstract: A skid vehicle for ice surfaces has at least two sliding skids and one driving wheel mounted in a frame. The axis of the driving wheel has a variable height and is biased by a spring. The driving wheel is driven or braked by a chain or similar power transmission mechanism. In order to avoid the undesirable and braking effect of the driving wheel during actual sliding, the spring applies a lifting force on the driving wheel and the power transmission acts against the force applied by the spring and lowers the driving wheel.

Title: High-pressure swash-plate pump
Inventor: UEBERSCHAER REINHARD
IPC: F04B1/29
Filed: 1990-12-18
Abstract: Described is a high-pressure swash-plate pump in which the angle of inclination ( alpha ) of the swash plate (4) producing the reciprocating motion of the piston (6) can be varied in order to change the piston displacement volume in the cylinder (7). The swash plate (4) is jointed on one side to a fixation element (3) and the angle of inclination ( alpha ) of the swash plate is adjusted automatically as a result of the equilibrium between the piston pressure and a force (F) exerted by a spring acting on the swash plate (4) in the opposite direction to the piston pressure. The pump is ideally suited for use in high-pressure cleaning equipment. In such an application, it is recommended that the spring force (F) acting on the swash plate (4) in opposition to the piston pressure is produced by at least one cup spring (9) located between the fixation element (3) and the swash plate (4). In a particularly preferred embodiment, the cup spring (9) has equally spaced slits radiating out from the recess (11) at the centre of the spring.

Abstract: La présente invention porte sur une méthode d'interpolation de valeurs chromatiques pour la transformation d'un espace chromatique initial en espace chromatique de sortie. L'espace chromatique initial est compartimenté en un réseau multidimensionnel; pour les points réseau sont prescrites, comme noeuds d'interpolation, des composantes transformées de l'espace chromatique de sortie; celles-ci, situées entre les points réseau, s'obtiennent par interpolation desdits noeuds. Aux fins de l'interpolation, les composantes d'une couleur initiale à interpoler sont décomposées en un multiple de l'espacement des points réseau et une valeur résiduelle, et les valeurs résiduelles sont classées par ordre de grandeur. Aux points réseau d'un sous-espace comportant la couleur initiale à interpoler, les noeuds d'interpolation sont choisis dand une série déterminée par le classement de valeurs résiduelles, et la couleur initiale est interpolée sur la base des noeuds d'interpolation choisis. La méthode peut s'utiliser sans accroître sensiblement le travail de calcul pour l'espace chromatique initial et l'espace chromatique de sortie avec un nombre quelconque de dimensions.
