Abstract: An electric circuit device comprising a connector for permitting removal and mounting of a cartridge with a circuit built therein, a processor for performing operation and processing using the circuit built in the cartridge, and a first reset circuit for supplying the processor with a first reset signal, and producing the first reset circuit when resetting is commanded by manual input or when a a power supply to the electric circuit device is turned on, means for producing a connection detection signal indicating whether or not a cartridge is mounted to the connector, and a second reset circuit for receiving a cartridge connection detection signal via the connector. When the connection detection signal is not inputted, the second reset circuit outputs a second reset signal. When the connection detection signal begins to be received, the second reset circuit terminates the second reset signal a predetermined time after the beginning of the reception of the connection detection signal. The processor executes the resetting when either the first reset signal or the second reset signal is inputted.

Abstract: An improved construction for a thermal engine, particularly a Stirling engine, comprising a two-part drive shaft. One part of the drive shaft (18) contains the swashplate mechanism (14) and is journaled on the engine housing (12) so that the component of force acting on the swashplate (16) which induces bending of the drive shaft (18) is reacted on the housing (12) by the journaling (52, 56) of the one part of the shaft (18). The second shaft part (62) is separate from but operatively coupled with the first-mentioned shaft part (18) and has its own journal mounting on the housing. The operative coupling in the disclosed embodiment is by means of a spline connection (60) between the two shaft parts (18, 62) which are in coaxial alignment. The second shaft part (62) is journaled on a housing part (42) which is separable from other parts (48, 54) of the housing on which the first shaft part (18) is journaled. A pressure seal (82) between the rotating drive shaft and the housing is provided between the second shaft (62) part and its housing part (42), and in this way the seal is sub­stantially isolated from the effect of bending loads imparted to the drive shaft by the swashplate mechanism.

Inventor: LANE HUGH ROGER
IPC: G01B21/20

Abstract: Metrological apparatus, particularly for measuring form, has a turntable 4 and a transducer 14 and associated stylus 12 mounted so that the tip 12a of the stylus is displaceable radially and vertically relative to the turntable 4. The problem of obtaining both high resolution and large range of operation is solved by using a transducer/stylus 12,14 having a resolution of 12 nanometres and a range of only 0.4 mm and mounting the transducer 14 on an arm 10 which is driven radially and/or vertically by a computer 30 in response to the output from the transducer 14 to cause the stylus 12 to follow the workpiece surface. High resolution data defining the rotary position of the turntable 4 and the radial and vertical position of the transducer 14 is provided by a photodetector/optical grating arrangement 23, 21, 31; 27, 19, 43 and associated interpolators 42, 44, 46. A novel computer architecture comprising a host 22, master 30 and slaves 33, 35, 37 provides an efficient system for controlling the apparatus and gathering data. Efficient gathering of data is further assisted   by the provision of means to cause the stylus 12 to traverse the surface of the workpiece at a constant speed, particularly as a function of the radial position of the transducer.

Abstract: The object of the invention is to produce a circuit arrangement for controlling the operating device of a circuit breaker while largely avoiding electromechanical components. With the exception of a relay (K1), used for the potential-free reporting of readiness to switch on, semiconductors and power semiconductors are used. A capacitor (C1) is used in conjunction with an electronic switch (V8) as an energy store, which capacitor is dimensioned for the maximum occurring running duration of the drive motor (M), for making available the control energy for a power semiconductor (V3) located in the circuit of the drive motor (M). A power semiconductor (V11) with a self-latching characteristic is used for operating a selection magnet (Y1) for the tensioned spring store.   The described circuit arrangement is suitable for low-voltage circuit breakers with a motor-store drive. <IMAGE>

Abstract: A method is specified for the continuous marking of articles (1) which are moved in their longitudinal direction, by means of which method annular features which are limited in the axial direction are applied by means of paint jets (2) on to the surface of the article (1). The paint jets (2) emerge under pressure from two nozzles (6, 7), which are arranged parallel to one another and oscillate continuously about an oscillating axis (5). If it is intended to use only one nozzle (6), the other (7) is closed by means of a 2/3 way valve (20). At the same time, a bypass (18) is opened, via which the paint quantity intended for the switched-off nozzle (7) is led away. The paint jet (2) of the nozzle (6) which continues to be used then remains unchanged.

Abstract: The invention relates to a process for repairing railway fastenings on wooden sleepers. After removing the old sleeper screw, which becomes loose in the course of time due to rotting of the wood, a thread is cut into the passage holes (11) of the ribbed sole-plate (2). New sleeper screws (33) with a single or double thread (37, 39) having a greater volume than the thread of the old sleeper screw are screwed into the boreholes (11) of the sleeper (1). One thread (37) of this single or double thread (37, 39) has a larger outside diameter that the passage hole (9) of the ribbed sole-plate (2). This thread (37) is matched to the thread (30) cut into the ribbed sole-plate (2). To permit simple guiding of the new sleeper screw (3) into the borehole (11) of the sleeper (1), the old cut-in thread (12) is used for guiding a thread cutter when cutting the thread (30) into the ribbed sole-plate (2) and for the new sleeper screw (33).

Abstract: A rear mirror for a motor vehicle has a continuously variable degree of reflection due to the fact that in front of its mirror plate (6) it has a transparent plate (3) whose distance from the mirror plate (6) can be varied by means of a device (8,16,18) controlled by a photoelectric cell which measures the incident light, and that the corresponding intermediate space (15) between the mirror plate (6) and the transparent plate (3) is filled with a light-absorbing liquid (8) and is connected to a reservoir (10) for the liquid (8). The intermediate space (15) is located together with the mirror plate (6) in a bag (9) which consists of transparent material and whose residual volume forms the reservoir (10). The liquid (8) is a magnetic liquid and behind the mirror plate (6) a magnetic coil (16) is arranged in such a way that when it is excited it draws the liquid (8) into the aforesaid intermediate space (15) counter to a restoring force (18) which presses the mirror plate (6) and the transparent plate (3) against one another. The light-absorbing liquid and thus the mirror can be of neutral colour or else having any desired colouring, for example blue. A maximum degree of reflection of over 90% is possible and a minimum degree of reflection of under 5%. <IMAGE>

Abstract: A method of controlling the rotational speed of a continuously variable transmission having a pair of pulleys which each includes a fixed pulley member and a movable pulley member, including the steps of decreasing and increasing the groove width between each pair of fixed and movable pulley members to respectively increase and decrease the rotational radius of a belt wrapped around the pulleys. A hydraulic clutch is pro­vided and is connected to and disconnected from the driving force of the transmission in response to clutch pressure applied thereto. A control section is provided for calculating a desired clutch pressure for the hy­draulic clutch. This desired clutch pressure is based on an engine torque value and a desired engine rota­tional speed. When the clutch is in a normal starting mode and certain other predetermined conditions are satisfied, the control section is used to adjust the desired engine rotational speed based on the temperature of the oil in the transmission.
