Abstract: SOLID-STATE COLOR IMAGER AND             METHOD OF MANUFACTURING THE SAME          Abstract of the Disclosure The invention provides a solid-state imager having a set of color filters disposed on a semiconductor body including photosensitive regions.  The color filter of a third color is formed by overlapping between filter members of a first color and a second color.  One of the filter members which has a spectral transmittance capable of transmitting light used for exposure in forming the filter members is provided as a lower layer closer to the substrate of the semiconductor body.  Thus, when the filter members are formed by the exposure process, a solid-state imager having good characteristics can be manufactured, because the lower filter member layer does not block light reflected from. the semiconductor body and permits the formation of uniform layer of the second color filter member, even in the parts where the first and second filter members overlap.

Abstract: ABSTRACT OPTICAL GLASS FIBRES AND METHODS OF FORMING SUCH FIBRES     In optical glass fibres formed of high-silica glass which is susceptible to the production of colour centres on drawing into fibres, the attenuation due to such drawing-induced colour centres is suppressed or reduced by incorporating from 1 to 100 (preferably 3 to 50) parts per million of cerium oxide in the glass from which the fibre is drawn, under oxidising conditions such that a signifi-cant proportion of the cerium is in the form of ceric ions and the total attenuation is not more than 20 dB/Km in the wavelength range from 800 to 900 nm.  The invention is applicable to the known process in which a batch of glass-forming materials is melted to form a phase-separable -silicate glass and a rod is drawn or cast from the glass, which is then phase-separated and leached to form a porous rod; the rod is stuffed with a dopant which increases the refractive index; the dopant is dissolved out from an outer region of the rod, which is collapsed by heating to produce a pre-form of a high silica glass with an inner region of higher refractive index; and optical fibre is drawn from the pre-form.  In this process, a cerium compound may be introduced into the batch, the melting and the drawing or casting of the rod then being carried out under oxidising conditions to ensure that a significant proportion of the cerium is in the form of ceric ions, or a cerium compound may be introduced with the dopant into the porous rod, the porous rod then being collapsed under oxidising conditions.

Abstract: POWER OUTAGE RECOVERY METHOD AND APPARATUS FOR DEMAND RECORDER WITH SOLID STATE MEMORY                 Abstract of the Disclosure A demand recorder includes a microprocessor for receiving data pulses representative of measured events and formats the incoming data into demand intervals. After a predetermined number of demand intervals, called a collec-tion period, the microprocessor transfers the data for more permanent storage to a solid state memory which may be removed for remote processing. The system has battery carry-over during a power outage, but the microprocessor prevents data transfers to the solid state memory. At the end of a collection period in which a power outage occurred, the micro-processor transfers the current data to a secondary portion of random access memory.  For subsequent demand intervals until power is restored and including any thermal recovery periods, the processor formats event data by assigning index numbers f or demand intervals in order of occurrence and stores data only for those demand intervals in which power consumption was actually measured.  After the system has returned to normal operation, the data temporarily stored in secondary RAM is transferred to the solid state memory and the data in primary RAM which is stored in compacted format is re-constructed into normal storage format in RAM with all intervals during which no event data was detected being zero-filled. As data is taken from primary RAM, converted into the original format and transferred to secondary RAM for storage in the solid state memory, the remaining data in primary RAM is advanced in memory, similar to the operation of a stack memory, so that as much space as possible is made available for data storage in the event of a subsequent power outage prior to the time all of the data in primary RAM is converted and stored in the solid state memory.

Abstract: IMPROVED SOY CONTAINING DOG FOOD                       ABSTRACT      The object of the invention is to improve the palatability of soy-containing dog foods.     It is difficult to make foods which are both low in cost and palatable to dogs.  Soybeans provide a range of economical proteinaceous materials and are widely used in dog foods.  When made under normal processing conditions, these soy-containing dog foods are less palatable than is desired,  The present invention improves these foods by select-ively treating the soybean proteinaceous material to improve its contribution to the overall palatability of the dog food, thereby improving the overall product palatability.  According to a preferred aspect of the invention, soybeans are selectively treated by roasting followed by quenching with a fat, such as soybean oil added in an amount of about 2 to 15% of the weight of the soybeans.

Abstract: FEEDBACK WELDER CONTROL SYSTEM                    Abstract of the Invention A control system for resistance welders of the type in which welding current is supplied to a workpiece through a transformer.  The system assures weld quality by monitoring the change in resistance across the weld during the welding operation without the need for auxiliary leads or separate sensing transducers at or near the workpiece and automatically terminates the welding current when a quality weld is made as determined by weld resistivity characterstics.  To accomplish this, the system monitors the discrete changes in the characteristics of the current in the primary of the welding transformer which occur as a result of changes in weld resistance.  Immunity to line voltage disturbances which can cause changes in current characteristics unrelated to resistance change in the weld is achieved by a modeling circuit which is subjected to the same line voltage disturbances as the actual welder circuit and which simulates the current characteristics of the actual welder but is unresponsive to the resistive changes which occur across the weld during the welding operation.  The system compares the current characteristics of the modeling circuit with those of the actual welding circuit and terminates the welding current in response to the true resistance change which occurs during weld formation.

Abstract: TITLE:  APPARATUS FOR COUNTING TURNS WHEN MAKING THREADED      JOINTS INCLUDING AN INCREASED RESOLUTION TURNS COUNTER     ABSTRACT OF THE INVENTION An apparatus for controlling the number of turns made and the torque applied during the operation of making a threaded joint includes a high resolution turns counter.  The turns counter senses the rotation of a member of the joint and gen-erates a pulsed signal, each pulse representing a predetermined increment of rotation.  The turns counter includes an idler wheel driven by one member of the joint and in turn driving an encoder which generates a relatively large number of pulses per revolu-tion of the idler wheel.  A presettable divide-by-N circuit is utilized to divide the encoder pulses to generate a pulse train to a monitoring and control apparatus for indicating whether a good or a bad joint has been made.  The divide-by-N counter can be preset to generate a predetermined number of pulses per revolu-tion of the joint member or pulses representing a predetermined percentage of a total number of turns to be made.  Also disclosed is an apparatus  as   provided for controlling the-speed of rota-tion of a joint member during the operation of making a threaded joint.  At lower speeds of rotation, a counter means receives clock pulses generated at a predetermined frequency and counts down from a stored value representing the elapsed time for a maximum rate at which turn signal pulses generated during prede-termined increments of rotation of the joint member should be generated.  If the elapsed time between the turn signal pulses is less than or equal to the stored time, a signal is generated to slow down the joint making operation.  At higher speeds of rota-tion, a counter means receives the turn signal pulses and counts down from a stored value representing the maximum number of turn signal pulses which should be generated in a predetermined time interval.  If the turn signal pulse total exceeds the maximum number during the predetermined time interval, the slow down signal is generated.

Abstract: ABSTRACT OF THE DISCLOSURE An electronic control means is utilized in an electrically actuated shift apparatus for a multi-speed axle including an electric power source and an electric motor coupled to actuate means for shifting the axle.  Four Darlington pairs are connected in a bridge configuration between the power source and the armature of the motor for bi-directional operation of the motor.  A manually actuatable shift lever has magnetic means attached thereto for generating mag-netic shift signals to magnetically actuatable switches.  The switches are connected in pairs with each pair alternately connecting a capacitor to the power source to charge and then connecting the capaci-tor to the input to a control Darlington pair which turns on two associated Darlington pairs of the bridge to allow current to flow through the motor for one direction of rotation.  In the same manner, the other pair of switches is actuated in the opposite sequence such that the other one of the capacitors is charging while the one capacitor is discharging to operate the motor in the desired shifting mode.  The discharging time of each capacitor is selected to fall between the minimum time required to actuate the motor and associated shift mechanism to shift from one speed to the other and the probable burnout time of the motor.  In an alternate embodiment, the Dar-lington pair bridge is replaced by a pair of diode transistor combinations with each transistor alter-nately being turned on by the associated capacitor. The switch pairs are replaced by a single pole, double throw switch connected between the power supply and the diodes to provide power to the motor and charge the capacitors.
