Title: Readily installed cleats for tire traction improvement
Inventor: FORTNER BENJAMIN A
IPC: B60C27/04
Filed: 1986-05-28
Granted: 1990-10-16
Abstract: Abstract of the  Disclosure An anti-skid device for ready application to a vehicle wheel, that is entirely installable from the outer or hub side of the wheel.  A primary embodiment of my device comprises at least three curved cleats, each having an inner surface and an outer surface, and each also having an integral attachment flange having a deliberate bend therein.  Each cleat is configured and designed to curve in a cantilever manner around the tread of the tire, and in a primary embodiment, the cleats are interconnected by a number of elongate connection rods.  The elongate assembly so formed can be placed around a tire, to encompass substantially more than half of the periphery of the wheel when the cleats are arrayed in an approximately equally spaced relation in contact with the tread of the tire, with the inner surface of each cleat normally disposed in a stand-away relation to the tread of the tire.  When the assembly has been tightened around the tire, to place it in its operational mode, the inner surface of each of the cleats is caused to depart from the stand-away relation to the tire tread, and to move into tight contact with the tire tread, thus to form a highly effective anti-skid device automatically eliminating any slack tending to form in the assembly due to the tire deforming as a consequence of rolling contact with the ground.

Title: Imaging devices
Inventor: BAKER IAN M
IPC: H04N5/335
Filed: 1986-09-18
Granted: 1990-07-17
Abstract: ABSTRACT IMAGING DEVICES In an imaging device, photocurrent generated by photovoltaic detector elements (1), e.g. cadmium mercury telluride photodiodes, is integrated in resettable capacitors (2), and an output signal (S) is derived by reading the potential of the capacitor (2) at the end of its integration period, e.g. using a source-follower MOST (3). In accordance with the invention, blooming-protection means (11,48,12) is coupled to each capacitor (2) to inhibit forward-biasing of the detector elements (1) and inversion of the capacitor potential when the capacitor (2) becomes fully discharged by excessive photocurrent. The blooming-protection means comprises a further gate (11) which has substantially the same threshold voltage as the injection gate (10) via which the photocurrent is injected into the capacitor (2). The further gate (11) which is connected at substantially the same control potential as the injection gate (10), is most conveniently formed together with the injection gate (10), as alternate integral parts of a common gate stripe (37) extending at one side of the capacitors (2). When a capacitor (2) becomes fully discharged, the further gate (11) coupled it to a current source (12) which supplies current to the capacitor (2) to stabilize the potential of both the capacitor (2) and its detector element (1) and so to protect against signal blooming.

Granted: 1991-01-08
Abstract: ABSTRACT OF THE DISCLOSURE       A housing is disclosed for an apparatus for deter-mining pregnancy in animals which includes a pressure acti-vated switch.  The housing includes a housing portion formed from integrally molded synthetic plastic which is selected to have a rigidity which varies with the thickness of the material.  The handle includes walls which define a chamber for receiving components of the apparatus including a pressure activated switch.  The walls are selected to have material thickness sufficient for the walls to be rigid in response to a pressure applied by an operator's hand.  A digit engaging portion of one of the walls is pro-vided with a reduced thickness sufficient for the digit engaging portion to flex into the chamber in response to a pressure applied by an operator's hand and returned to a rest position when pressure is withdrawn.  The pressure activated switch is included within the chamber and has a pressure activated element opposing the digit engaging portion.

Title: Torque measuring device having dual range load cells
Inventor: D ANGELO SERVERINO
IPC: G01L3/16
Filed: 1987-02-20
Granted: 1991-07-23
Abstract: ABSTRACT OF THE DISCLOSURE      A torque measuring device having dual range load cells is provided featuring high accuracy over a large range of torque measurements.   A pair of load cell assemblies act on the torque arm of a dynameter torque balance.  A compliant element is employed to connect the torque arm to a low range load cell assembly and lost motion means are provided by the high level load cell assembly.  Low torques imposed on the torque balance cause only the low range load cell to be loaded.  The low range load cell assembly is selected to provide high accuracy over the low torque range levels.  Once a predetermined threshold torque is applied, the deflection of the compliant element permits the torque arm to engage the high level load cell assembly.  Torques beyond the threshold level are determined by summing the measured torques of both load cell assemblies.      Several embodiments are described which disclose various means for providing a compliant linkage for the low range load cell assembly and for providing a lost motion coupling for the high range load cell assembly.

Title: Optoelectronic signal recording medium and method of making same
Inventor: KUEHNLE MANFRED R
IPC: G11B7/24009
Filed: 1987-06-10
Granted: 1991-11-26
Abstract: Abstract of the Disclosure An optoelectronic signal recording and storage medium including a base layer, a conductive layer, a photoconductive layer and storage layer has a coherent crystal morphology throughout, even though the chemical and electrical properties of its layers are by choice dramatically different.  The base layer is preferably made of monocrystalline sapphire grown in a manner as to allow the growth of the other layers directly on a surface of the base layer without the need to grind and polish that surface, thereby minimizing internal defects in the medium.  The monocrystalline base layer also allows the acceptance of exeptionally uniformly distributed charges over wide areas of the medium, thereby enabling the medium to locally record and store minutely differing optoelectronic signals on a background of minimal noise, thus facilitiating low light level electronic or optical recording and long term storage of signals and minimal energy readout of those stored signals.  The medium base layer can be thin enough to be flexible and transparent and yet to have great strength to provide a firm foundation for the other medium layers. method of making the medium is also disclosed.

Title: Early end of tape sensing for a cache buffered tape drive
Inventor: HUNTER DAN A
IPC: G11B15/093
Filed: 1987-09-25
Granted: 1990-11-13
Abstract: ABSTRACT An early end of tape sensing subsystem for a data processing system, including a host computer, a cache buffer, and a magnetic tape drive subsystem utilizes outputs dependent upon the movement of a capstan wheel, swing arm, and file reel of the magnetic tape drive subsystem, determining the net movement of tape therein in order to measure the circumference of the file reel plus tape thereon.  Whenever a series of valid readings from a conventional sensor are obtained indicating that the circumference of the file reel plus tape is approaching that of the circumference of the file reel itself (i.e., no tape on the file reel), a signal is sent to the microprocessor controlling the cache buffer, said signal indicating that the end of the tape is approaching.

Title: Reed solomon error correction code encoder
Inventor: WENG LIH-JYH
IPC: G06F11/10
Filed: 1988-05-06
Granted: 1993-01-19
Abstract: ABSTRACT OF THE DISCLOSURE         An encoder encodes a sector of data to produce ECC symbols using a GF(210) code by first appending one or more pseudo data bytes to the sector data bytes.  The data string of sector data bytes and pseudo data bytes are then encoded to produce a desired number of 10-bit ECC symbols.  Two selected bits from each ECC symbol are compared to a known bit pattern.  If the selected bits match the pattern, the bits are truncated and the remaining 8-bit symbols are concatenated with the data string to form a codeword.  The codeword bytes can later be decoded, and any error correction performed, by appending the bit pattern as necessary.          If the selected bits do not match the pattern, the pseudo data bytes are modified such that encoding the data bytes and the modified pseudo data bytes produce 10-bit ECC symbols with the selected bits matching the bit pattern.  The selected bits are then truncated and the remaining 8-bit symbols are concatenated with the data string to form the codeword.
