IPC: A61F2/30

Granted: 1984-06-15
Abstract: A prosthesis for the surgical replacement of a dysfunctional knee joint. The prosthesis includes a tibial platform, one or two tibial bearing inserts, and a femoral component. In a unicompartmental embodiment of the invention, the tibial platform includes a spike for securing the tibial platform to the tibia. The tibial platform, in the unicompartmental embodiment, includes a track, which may be curved, and which is slidably engaged in dovetail fashion by a tibial bearing insert. The superior surface of the tibial bearing insert is concave spherical, designed to slidably engage the inferior surface of the femoral component. The inferior surface of the femoral component is generally convex spherical, with radius of curvature slightly smaller than the radius of curvature of the tibial bearing insert. In a bicompartmental or tricompartmental embodiment of the invention, the tibial platform includes two tracks, each of which may be curved, and each of which slidably engages in dovetail fashion a tibial bearing insert. The two tibial bearing inserts each engage, via their superior concave spherical surfaces, mating inferior convex surfaces of the femoral component. The two curved tracks are in general not concentric; rather, the center of each falls on a line normal to the plane of such curved track and passing through the center of curvature of the concave spherical surface of the tibial bearing insert of the other curved track.

Abstract: The metering apparatus for small volumes of liquid in the milliliter and microliter range comprises a piston/cylinder system driven by a direct-current motor. The piston stroke is measured by means of an optical path-length measuring system. For this purpose, a slide-rule pulse scale provided with a regular line grid is affixed to the piston. The light from a light transmitter passes through the slide-rule pulse scale and a stationary scanning plate which likewise is provided with a regular line grid, and to a light receiver. The pulses of the light receiver are digitalized in a pulse conditioning circuit and fed to a counter adapted to be preset by means of a coding switch. The counter position acts upon a braking and rotative-speed regulating circuit in such a way that regardless of the preset desired value of the rotative speed the speed of rotation of the motor is reduced to a small value as the final value is approached. As soon as the preset volume has been metered and the counter has reached the zero position, the motor is brought to a dead stop through a motor-control logic circuit with the aid of a reverse voltage. During the stopping process the no-load voltage of the motor is measured by means of a zero-voltage comparator at regular intervals. A pulse monitoring circuit serves to measure and regulate the piston-stroke speed and to turn off the motor in case of a mechanical defect. Motor and electronic systems are supplied with current from dry cells or storage batteries, a power supply being optionally provided to charge them.

Abstract: A microprocessor-controlled coin handling apparatus, for example for a vending machine, has a plurality of change tubes (22, 24, 26) each of which is provided with a single level sensor (150, 152) for determining whether or not the number of coins in the respective tube (22, 24, 26) is greater than a predetermined number. The microprocessor (50) keeps a count of the coins in the tube (22, 24, 26). When the power is turned on, the count is set to zero if the sensor (150, 152) indicates that the number of coins is less than the predetermined number, and is set to a predetermined "full" number (FULNUM) otherwise. The microprocessor (50) increments and decrements the counts as coins are delivered to and dispensed from the change tubes (22, 24, 26). Whenever the level of coins rises or falls such that the sensor output changes, the coin count is automatically corrected. Also disclosed is a non-volatile memory (60) for storing parameters determining how the coins are handled. Keys (102, 104, 106) are provided for accessing and altering the contents of the memory (60). Some contents are accessible in a first mode, whereas other contents are inaccessible in this mode, and require a second or third access mode to be entered. At least one location can be altered in a first manner during one of the access modes, and in a second manner only during a different access mode.

Abstract: The invention disclosed herein relates to a biasing means provided in one end of a card-receiving slot of a card edge connector. The biasing means includes a spring loaded wedge slidably positioned in a sloping passage at one end of the slot. The wedge includes a vertical surface which engages a side of the card as the card is inserted in the slot. The wedge moving down the sloping passage increases the slot length to accommodate the card width without exerting significant longitudinal force against the end walls of the connector. Further, the wedge cannot be moved up the passage by an uneven force being exerted on the card; accordingly, the card can only be removed from the slot in a straight line.

Abstract: The invention relates to a penetrator (1, 11) made of heavy metal, such as, for instance, tungsten heavy metal or depleted uranium, for driving-cage projectiles which have the penetrator led by the driving cage in the gun barrel. The driving cage (6, 12) detaches itself from the penetrator after the launch. The penetrator (1, 11) shows lower strength and higher ductility in the middle portion (d) of its length than in its head portion (c) and, in its tail portion, it shows higher strength and lower ductility than in its middle portion (d) and lower strength and higher ductility than in its head portion (c). This shall decrease the risk of fracture when striking an armour. The varying strength values in the head portion (c), in the middle portion (d) and in the tail portion (e) are obtained by cold-hammering under varying degrees of deformation, by sintering from various powder mixtures or by varying partial heat-treatment in the various portions (head portion c, middle portion d and tail portion e), and these measures can be applied individually or in combination. At least one pilot core (14, 15) which is only loosely connected to the penetrator (1, 11) can also be fitted to the head portion.

Abstract: A clocked direct voltage converter with potential separation includes a control circuit for controlling the switching times of a switching transistor arranged on the primary side of the voltage converter, in which voltage converter voltage proportional to an output quantity is chopped by a controllable switch. The chopped voltage is transmitted by a transformer to the primary side of the converter, is then rectified, filtered and supplied to the control circuit. In order to obtain the largest possible control range for the converter, a further transformer is provided which transmits oscillation signal of an oscillator of the control circuit to the controllable switch on the secondary side voltage converter. By means of this oscillation signal, the controllable switch is controlled.
