Abstract: A ring of paddles is provided the lower ends of which are engageable under the upper bead of a longitudinally-lying tire for lifting the latter and positioning it in a press. The paddles define an enclosure for the press diaphragm to prevent the latter "ballooning" out above a tire or tire carcass pre-formed to C-section and thus of smaller axial extent than its diaphragm when inserted in the press. Spreading of the lower ends of the paddles to engage under the tire bead is effected by gravity as the device is lifted and locking means is provided to prevent such spreading when desired.

Abstract: A safety ski binding with a sole plate having structure facilitating a connection of a ski boot thereto. The two ends of the sole plate each engage a ski-fixed holding part and, through the provision of a locking mechanism prevents the sole plate from rotating and lifting off from the ski in the area of the ends of the sole plate. The sole plate is rotably supported approximately in its center about a ski-fixed pin which extends perpendicularly with respect to the upper surface of the ski and the pin is received in a recess in the sole plate and has structure for preventing removal of the sole plate. A sleeve is provided between the exterior surface of the pin and the interior wall of the recess in the sole plate, which sleeve is movable telescopically along the wall of the recess, and the maximum path of movement of the sleeve in the recess is fixed by stops.

Granted: 1985-04-19
Abstract: A sensitive high speed clocked comparator for use with low level differential logic circuits which utilizes an amplifier, a Gilbert Gain Cell, and load devices to amplify the difference between analog voltages being compared, and a high speed latch to increase the output voltage level of the Gain Cell up to the level of logic signals used in low level differential logic circuits. The circuit has two modes, a "follow" mode wherein the amplifier and Gilbert Gain Cell cause an unbalance in the currents through two load devices responsive to any difference in input voltage, and a "latch" mode wherein a latch causes the current unbalance to increase and to latch. The modes are sequentially selected by clocking.

Granted: 1982-05-14
Abstract: A safety binding for a ski including a body having a jaw for holding a ski boot and a support fixed to the ski. The support has a rear transverse face with two recesses therein, and a front transverse face. The body includes a transverse face having two projections thereon, each adapted to engage one of the recesses of the support. The recesses and projections define two lines of support converging at a point above the ski and disposed, respectively, on either side of the longitudinal plane of symmetry of the ski, so that the body can pivot along either one of the lines of support. A spring urges the rear face of a piston against the front transverse face of the support so that the rear traverse face of the support is urged against the transverse face of the body. The rear face of the piston includes two lines of reaction converging toward the ski. Because the two lines of reaction are on the rear face of the piston, the return moment of the binding increases continuously as the binding pivots further away from a central retaining position, thereby ensuring the rapid return of the binding whatever the displacement of the boot. In addition, because lines of reaction are on the rear face of the piston, the line of contact between the rear face of the piston and the support is constant.

Abstract: An apparatus for receiving optically encoded binary data transmitted over an optical fiber from an optical transmitter device coupled to another data processing system. The receiver apparatus is used to convert the light signal carrying the subject data into TTL level digital logic signals. The receiver apparatus is comprised of circuitry for converting the optically encoded data into electrical signals in serial format, and circuitry for converting these electrical signals into TTL level digital signals in parallel format for use by a user device. The primary advantage of the apparatus disclosed here is the ability to substitute a single optical fiber for a plurality of parallel copper wires for carrying data between one data processing device and another with little or no loss in speed due to the larger bandwidth of optical fibers. Another significant advantage is the ability to couple data processing systems directly over much larger distances than possible with average cost parallel copper wire electrical cables. Higher noise immunity and communications security is also enjoyed. In the preferred embodiment, the receiver apparatus comprises a photodiode for converting the light signal into an electrical signal followed by an amplifier for changing the electrical signal to TTL digital logic levels. A clock generator and header detector recover a clock signal and detect the receipt of a header signal indicating transmission of a serial format data packet has commenced. A serial in and parallel out shift register/data latch storage buffer combination utilizes a signal derived from the recovered clock signal to shift the incoming data bits into the shift register and latch them into the data latch output buffers in parallel format when a counter signals that an entire data packet has been received.

Abstract: A carrier element for an IC module (integrated circuit) comprising leads which are connected at one end with the corresponding terminals of the module and at the other end have a contact surface. The ends of the leads running into the contact surfaces extend unsupported beyond the edge of the carrier so that they can be bent into the desired position according to the intended purpose of the carrier element. When the leads are bent around the carrier plane towards the back surface of the module and united by using a castable material in a casting the result is a compact carrier element well adapted to the dimensions of the IC module. For the incorporation of the carrier element according to the invention into an identification card the free ends of the leads can be directed through corresponding recesses in the cover film of the card. During lamination of the layers of the identification card the ends of the leads are bent onto the cover film and thus pressed into the film material.

Date Aug. 4, 1986.A surgical apparatus for partially modifying the curvature of the cornea of an eye while the eye is within the patient is disclosed. The device is able to ablate a zone of corneal material in the form of a lenticular lamina. The thickness of the lamina at any particular point on the cornea surface varies as a function of the radial distance between that point and the central optical axis of the eye. The surgical apparatus comprises: a source of light (31) capable of emitting a beam of light (4) having a wavelength which is about 200 nanometers; an optical system (32) for directing and focusing the beam of light onto the desired zone of the cornea in order to ablate a lamina of material of the desired dimensions; and, a series of diaphragms and screens for obscuring varying portions of the zone of the cornea undergoing ablation in order to effect differential irradiation of the corneal surface. The longer the light beam (4) is allowed to impinge a particular portion of the cornea, the more corneal material removed from that spot and the greater the thickness of the lamina ( 2 and 16), and vice versa.

Abstract: The exchange device (not shown) is installed in a lock and emits a modulated carrier wave. The key (2) possesses circuits (27, 28, 29, 23) for demodulating the modulated carrier wave received and for reconstructing a first signal (PR) representing the information emitted by the exchange device, and processing circuits (23, 25, 30) receiving the first signal (PR) and generating a second signal (D) representing the information to be transmitted. The second signal causes an impedance (26) to vary abruptly, so that the charge detected by the exchange device varies and so that the information is thereby transmitted to it. Moreover, the impedance (26) is designed as a limiter. A clock signal (41) is obtained from the modulated carrier wave by clipping, and the supply voltage (AC) is obtained by rectification and regulation. The system makes it possible particularly to use a contactless connection between the key and the lock, for example by means of a single pair of coils.
