Abstract:
A number wheel has a first circular portion provided with a center hub having an axis, and with a plurality of passages which are spaced from and asymmetrically distributed about the hub and each of which has an axis paralleling the axis of the hub. A discrete second circular portion has a center portion received in the hub and centers the second circular portion with reference to the first circular portion adjacent one axial end of the latter, and a plurality of projections each of which is frictionally received in one of the passages.
Abstract:
In a wire printer, in which a plurality of selected printing needles are simultaneously advanced to print a character, each printing needle is operated by a lever to which the plunger armature of an electromagnet is secured at a smaller distance from the lever fulcrum than the printing needle so that the needle stroke is greater and faster than the armature stroke. The lever is preferably resilient, and the mass of the needle is selected so that upon actuation of the armature, the lever is at first slowed down by the mass of the printing needle and then recoils to move at a higher speed than the armature, and to continue in a free stroke when the armature is stopped at the end of the armature stroke. Preferably, the attaching end portion of the wire which forms the printing needle, is wound in a coil around the lever to permit resilient yielding of the printing needle when abutting a printing surface at the end of the needle stroke.
Abstract:
An apparatus for automatically recording time periods during which the motor car stands still and is driven, respectively, includes a transmission having a constant speed input, and a varying speed input driven by a device for measuring the distance of travel by the car, and a control gear and control cam for shifting a recording arm to a first recording position when the car is at a standstill, and to a second recording position when the car is driven so that distinguishable graphs are recorded. The graph representing the driven condition of the car is preferably a zig-zag line. The transmission preferably includes an inner thread in the control gear, and a projecting stud on a shaft driven by the variable input and meshing with the inner thread.
Abstract:
To each counter wheel of a counter, a clearing cam with cam track portions analog to the values represented in digital angular positions of the counter wheel, is secured. Spring-biased sensing members are moved toward the respective cams and abut cam track portions analog to the digits stored in the respective counters. The sensed value is transferred from the sensing members, whereupon the counter wheels are unlocked by retracting tens-transfer means, permitting the cams to be pressed by the sensing members to a clearing position in which the counter wheels are set back to zero.
Abstract:
Two successive ordinal toothed counter wheels are connected by toothed transfer means to make a tens-transfer once during each revolution of the counter wheel of the lower order. The teeth of the counter wheels and of the transfer means are cut out and hollowed so that the teeth are resilient and dampen impacts thereon during the transfer operation.
Abstract:
AN APPARATUS FOR EVALUATING AT LEAST ONE RECORDING ON A ROTARY DIAGRAM CARRIER WHICH HAS A STARTING MARK AND IS SENSED BY SCANNING MEANS DISTINGUISHING DIFFERENT SECTIONS OF THE RECORDING, AND PRODUCING A START SIGNAL WHEN SENSING THE START MARK. A PULSE GENERATOR GENERATES TIME PULSES WHICH ARE COUNTED BY A TIME COUNTER PRODUCING AN END SIGNAL WHEN A PREDETERMINED NUMBER OF TIME PULSES, CORRESPONDING TO 24, OR 12 HOURS, FOR EXAMPLE, IS COUNTED. WHILE SENSING THE DIFFERENT SECTIONS OF THE RECORDING, THE SCANNING MEANS TRANSMIT DIFFERENT SIGNALS REPRESENTING THE RESPECTIVE SECTIONS OF THE RECORDING, TO DISTRIBUTING GATES WHICH PERMIT THE PASSAGE OF CORRESPONDING NUMBERS OF TIME PULSES TO DIFFERENT STORAGE COUNTERS WHICH ARE SEPARATELY READ OUT WHEN THE END SIGNAL IS PRODUCED AFTER 24, OR 12 HOURS, FOR EXAMPLE.
Abstract:
THE FARE REPRESENTING SHAFT OF A TAXIMETER IS DRIVEN BY ONE-WAY CLUTCHES FROM DISTANCE AND TIME DRIVE MEANS. WHILE THE DISTANCE DRIVE MEANS DRIVE THE SHAFT AT VARYING SPEEDS, THE TIME DRIVE MEANS HAS A MOTOR WHICH ROTATES AT A CONTINUOUSLY CONSTANT SPEED SO THAT UNDESIRED SIMULTANEOUS DRIVING OF THE SHAFT BY BOTH DRIVE MEANS, CAN TAKE PLACE ONLY MOMENTARILY WHEN, DURING DRIVING OF THE SHAFT BY THE DISTANCE DRIVE MEANS, THE VARYING SPEED OF THE SHAFT IS MOMENTARILY EQUAL TO THE CONSTANT SPEED AT WHICH THE TIME DRIVE MEANS DRIVES THE SHAFT.
Abstract:
A taximeter apparatus, including distance and time measuring devices, a calculator, and an indicator, is mounted in a housing into which any one of several control units can be selectively inserted. Each control unit has plugs which engage sockets in the housing when the control unit is inserted and operative. Each control unit has different manual operating means for selecting functions of the taximeter apparatus, such as calculating different charges in accordance with different rates.
Abstract:
A tachographic measuring and indicating apparatus which is composed of at least one measuring unit, at least one transmission unit, and an indicator unit driven from the measuring unit through the transmission unit. The measuring unit, the transmission unit, and the indicator unit are detachably supported on a supporting casing in such a manner that each unit can be separately manufactured and combined with the other units, and also individually removed for service or adjustment.
Abstract:
The distance travelled by a car, and the time periods during which one, or two operators, actually drive the car or are performing auxiliary services like waiting or loading, are simultaneously recorded by at least two oscillatory recording means driven by rotary operating means rotated by one synchronous motor receiving pulses from two pulse generators, one of which is activated when the car travels a distance, and the other of which is activated by a manual switch. The polarity of every alternate pulse is reversed by an electronic control circuit so that the synchronous motor is driven by alternating current. Switch means cause a rotation of the synchronous motor in opposite directions during movement and standstill of the car. The operating means associated with the travelled distance, is driven only when the motor rotates in one direction, while the operating means associated with the working time periods, causes different oscillations of the respective recording means when the motor rotates in opposite directions.
