Abstract: Starter circuits are disclosed for a fluorescent discharge tube (10) of the type having a pair of heater cathodes between which the discharge is struck and which are connectable to the mains supply (V.) through a ballast inductor (L). The starter circuit (20) includes a thyristor (SCR) that conducts current through the ballast inductor and heaters on half-cycles on one polarity. A gate control circuit (30) includes a capacitor (C 1 )that receives a controlled (by C 2 , Z 1 ) bias voltage increment in each such half-cycle to eventually terminate triggering of the thyristor (SCR). Preferably an automatic switching arrangement (C 3 , Z 2 ) changes the value of capacitance to give a lesser rate of increment upon a certain bias level being reached to provide a two phase start operation that eventually times out. Alternatively, the maximum bias may be clamped and a positive temperature coefficient resistor (PTC) carrying the heater current terminates the second phase upon heating to a predetermined resistance. The starter circuit (20) also includes a non-linear dielectric element (NLDE) that cooperates with the inductor to generate striking voltage for the tube and that is connected in an ignition circuit including a capacitor (C s ) connected to the thyristor (SCR) to charge and maintain the NLDE quiescent during normal operation but to be discharged by the thyristor (SCR) during starting to allow the NLDE to achieve saturation and coact with the ballast inductor (L).

Abstract: The device includes a control lever (1) and push-button for moving a figure on a video screen. The linear movements of the lever are slowed down by a double effect oil damper (7). Since the oil damper limits the speed at which the lever may be moved, there is a proportional relationship between the force applied by the operator, and the speed at which the figure moves across the screen. The lever moves in a cardan joint (4) allowing movement in two perpendicular directions - with an inductive system providing the electronic control. A toothed wheel in the housing of the control allows the figure to be rotated on the screen.

Abstract: The system has a map-aided localising device, a navigation system and a route-seeking device. The localisation and navigation system do not require any external triangulation stations. Before every road crossing, the route-seeking device selects that direction from the range of possible directions which will reach the destination by the optimum path in a particular case. If any other direction is taken, the route-seeking device again determines the optimum path on the basis of the chosen direction, i.e. of the position actually reached.   <IMAGE>

Abstract: The wall according to the present invention comprises a gravity support structure with a plurality of compartments or cells which are filled with bulk-material and surrounded or subdivided by flat and flexible envelope material, and on one front side or on both opposite front sides of this gravity support structure a fore-part, preferably in the form of a supporting grid structure, which is positively or frictionally connected with said gravity support structure. Such combined wall structure can be used for slope supporting as well as for noise absorbing or partition purposes, in the latter cases e.g. in the form of a stand-alone structure. An essential function of the fore-parts is the protection of the front portions of the envelope material holding the bulk material filling against violation and solar irradiation. The stability of the combined wall is greatly enhanced by anchoring the fore-parts to the gravity support structure be means of comparatively inexpensive tensile elements.

Abstract: A power assist steering gear for use in vehicles having a housing that defines a chamber. A piston dividing the chamber into first and second chamber portions. The piston is movable through a work stroke in opposite directions in the chamber. A steering valve directs fluid pressure into the first chamber portion and vents the second chamber portion to effect piston movement in a first direction and directs fluid pressure into the second chamber portion and vents the first chamber portion to effect piston movement in a second direction. An input shaft moves to effect actuation of the steering valve. A relief valve for communicates the first and second chamber portions when the piston is near the end of its work stroke. The relief valve has a valve member and valve seat which are movable between a closed position blocking communication between the first and second chambers and a fully open position establishing communication between the first and second chambers when the piston reaches the end of its work stroke. A press-fit connection effects adjustment of, in response to movement of the input shaft, the position in the piston path at which the valve member and valve seat move relatively to an open position.

Abstract: In a gaming machine with a win pay-out, according to a random function determined by a random generator (8-10) a combination of m symbols, representing a win in at least one of a plurality of win classes, each with a predetermined win probability, can be played (drawn) from a predetermined stock of n symbols ("1", "2", "3" to "49") and from the symbol stock a number of m symbols can be set optionally as a play combination for the player, m being smaller than n and the higher win probabilities being predetermined multiples of the lowest win probabilities. To allow a player to play on a coin operated gaming machine which, despite the fact that chances of a win have actually changed, gives the player essentially the same play stimulus with apparently the same chance of a win as in the game familiar to him, from the number (m + 1), increased by 1 (a missing number ("blank")), of the symbols forming the play combination a number x (0-6) can be played automatically according to a random function, as a win class with a higher win probability than corresponds to a probability of 1 to "n over m" for the win class of lowest win probability, with the predetermined multiples for the higher win probabilities being taken into account.
