Title: Rapid thermo-magnetic recording disk printer and master disk for same
Inventor: KRYDER MARK HOWARD
IPC: G11B5/86
Filed: 1984-04-24
Abstract: A master disk for simultaneous recording of all information upon a thermo-magnetic recording disk, has a layer of a heating-energy-reflecting material supported by a substrate of a material substantially transparent to the form of heating energy used. The reflecting material layer is apertured at locations at which the disk-to-be-recorded is to have a bit of digital information of opposite binary value from the binary value of locations at which the reflecting layer remains intact. The master disk is placed adjacent to a recording disk previously having all domains therein magnetized in a first direction, and a beam of heating energy, such as light and the like, is directed through the master disk, in the presence of a magnetic field of direction opposite to the direction of the previous magnetization of the domains. The magnetization of domains situated under apertures in the reflecting layer is reversed, responsive to the heating energy beam and the opposite-direction external field, to rapidly write the binary information from the master disk onto the recording disk.

Abstract: An improved process and an improved composite bearing material produced thereby comprising a hard metal backing strip having leaded-bronze bearing lining tenaciously bonded to at least one face surface thereof and wherein the bearing lining is characterized by having the lead constituent thereof substantially uniformly distributed throughout the lining matrix in the form of extremely fine- sized particles providing improved operating characteristics to the bearing materials fabricated therefrom. In accordance with the process aspects of the present invention, the steel backing strip is provided with a metallic plating composed predominantly of nickel to at least the face on which a prealloyed leaded-bronze powder of a controlled composition is applied and is thereafter sintered at a controlled temperature for a short period of time sufficient to effect a liquid phase sintering of the powder together and the formation of a bond between the powder layer and the metallic plating on the face of the backing strip whereafter the sintered composite strip is cooled and is compacted usually at temperatures below about 300°F. (149 °C) to effect a substantially complete densification of the powder layer. The composite strip is again reheated at a controlled temperature and for a brief period of time sufficient to further enhance the physical properties of the bearing lining and to further enhance the strength of the bond between the lining and backing strip under controlled conditions to inhibit growth of the finesized lead particles into undesirable larger particles. The composite strip is thereafter again cooled and may be subjected to a further compaction at moderate warm temperatures to achieve still further densification and to impro- ye the physical properties and sizing of the composite strip.

Abstract: A microcomputer controlled coin telephone set prevents coin call fraud and also checks the operational readiness of the telephone set to prevent the acceptance of coins into a hopper for later collection by a coin box unless or until the set is fully functional. Capable of being interrogated remotely, a local memory is used for storing coin deposit information and generating coin deposit signals in order of deposit to a central office. 
     In those instances where the line power drops below that necessary for full operation as a coin telephone, low power sensing circuits (111) convert the telephone to the POTS mode which allows speech and dialing capabilities. Similarly, any type of chute failure, or a full hopper causes the telephone to revert to the POTS mode. While in the POTS mode, any coins deposited in the telephone are returned to the customer.

Abstract: A multi-drop local area network utilizes alternating current power lines as a transmission channel. Identical transceivers are used as a master and as up to 255 slaves. Each transceiver comprises modulator and demodulator units and a microprocessor control unit which may be connected to a host. The modulator and demodulator are connected to the alternating current power line through a high pass filter comprising a split bobbin, iron core transformer having an air gap which also provides impedance matching. The demodulator includes a clipper and analog circuitry providing a band pass filter and generating a square wave corresponding to the received carrier. A state machine acting as a digital filter produces a received carrier signal only when each half cycle of the carrier square wave is of the proper duration and the carrier signal has existed for slightly more than one half of the transmitted bit duration, which is a predetermined number of carrier cycles. 
     The microprocessors are programmed to provide for block ahead acknowledgment, alternate transmissions between master and slaves; each block message comprises an acknowledgment non-acknowledgment bit, a message sequence bit, a polling sequence bit, and a longitudinal redundancy check. The carrier frequency utilized lies in the range of 20 to 40 KHz and preferably within the range between 27 and 33 KHz for a power line transmission channel. Error free 1200 Baud transmission rates are achieved in full duplex. Higher carrier frequencies and transmission rates are possible over less noisy transmission channefs such as wire pairs.

Abstract: A shift actuator for a vehicle transfer case includes a bidirectional electric motor for positioning gearing in the transfer case. An indicator mechanism associated with the drive train between the motor and the transfer case provides electrical signals indicative of the actual position in, and thus operating state, of the gearing in the transfer case. A selector switch provides electrical signals indicative of a desired operating state of the transfer case gearing. An electronic control is responsive to an input from the selector switch and to the indicator mechanism for effecting rotation of the motor in a predetermined one or other direction to attain the desired operating state. The indicator mechanism includes a contact plate, which rotates with the drive train, and a set of stationary contacts. A conductive pattern on the contact plate identifies the positioning of the operating states of the transfer case gearing. Signals indicating the condition of the vehicle, as its speed and the state of its transmission, serve to allow or to inhibit certain responses to certain selected states of the transfer case gearing.

Abstract: In a motor-driven screw driving device, a drive unit and a drive member are located within a housing and are interconnected by a torque-limiting coupling. The coupling is adjustable by changing the force applied to a spring element. The spring element is supported within a stop sleeve located within the housing and the stop sleeve is axially displaceable relative to the housing. A depth stop on the drive spindle is adjustable relative to the stop sleeve. An actuating sleeve accessible on the exterior of the screw driving device affords the adjustment of the stop sleeve and the depth stop. A connecting element is secured to the actuating sleeve and is in engagement with the depth stop so that the actuating sleeve and depth stop can be rotated as a unit. The connecting element is selectively engageable with the stop sleeve so that the actuating sleeve and stop sleeve can be rotated as a unit for adjusting the torque-limiting coupling.

Abstract: A unique nozzle assembly (11, 12) is provided for placement within the chamber (4) of a web dryer (1) and closely adjacent a housing web slot (5, 6). The nozzle assembly generally comprises a Coanda-type nozzle (27) and a supplemental nozzle (33) disposed on the assembly so that it is positioned between the Coanda nozzle and the housing wall (3). Both the Coanda and supplemental nozzles are supplied with air from a common manifold (13) connected to an external air source. An air flow control device (34, 35) is provided for the individual air flow paths in the assembly to suitably balance the velocities of the two discharging air jets. To prevent any transient air currents inside the dryer chamber from causing web or air flow instability, a seal (43) is provided between the improved nozzle and the dryer housing wall. The seal is disposed along the head end of the nozzle; that is, closely adjacent the nozzle jet discharge ports. A pair of improved nozzles are usually disposed adjacent each housing web slot, one on each side of the web. The exact relative positioning of the nozzles in a pair may be varied according to the particular conditions encountered. To overcome any problems caused by narrow webs or a slight amount of cool room air infiltrating the warmer dryer environment, a labyrinth of expansion chambers (66) may be positioned between the inner dryer wall (3) adjacent the slots and the improved nozzles (58, 65) as per FIG. 7. In the present embodiment, the labyrinth forms part of the nozzle assemblies (44) themselves.
