Abstract: A first wrap adapted to wrap around the lower leg generally over the medial malleolus and above the lateral malleolus is connected by a strap to a second wrap adapted to wrap around the lower leg generally on the upper portion of the gastrocnemius or below the popliteal fossa. The first wrap has a holster for carrying a firearm and which holster is secured approximately over the medial malleolus. The holster may be selectively detachable to allow a selection of holsters to be secured to the first wrap. The second wrap carries the substantial portion of the weight of load of the assembly, and of any holster and firearm secured thereto.

Abstract: A layer of polyethylene or polyvinal chloride bonded to a layer of polyurethane material in turn bonded to a surface of material such as concrete or metal comprises a combination of a coating and a liner which prevents corrosion of the coated, lined material and is substantially free of pin hole penetrations. A method of spray applying atomized polyurethane material to a surface to be coated, such as concrete or metal, and thereover applying a layer of polyethylene or polyvinal chloride material is described. A machine for spray applying polyurethane material from a nozzle atomizes the polyurethane material at elevated pressures and temperatures.

Abstract: A finger positioning guide includes a flat surface positionable between the neck and strings of a stringed instrument to present sets of uniformly colored spots beneath certain of the strings at predetermined distances along the neck. The flat surface is positioned in relation to the neck and the strings by a slot or a plurality of slots adopted for engaging frets and the nut. An edge limiting device, appended to the surface to comprise the guide and further position it in relation to the neck, may include a clamp shape clamping the guide to the neck.

Abstract: An apparatus for testing the calibration of hard disk substrate tester includes a calibrating micrometer moving a known surface to at least two distances from a non-contact detector in the hard disk surface tester and a known distance from each other, and further includes a piezoelectric transducer mounted to the known surface moved by the calibrating micrometer, and an oscillator oscillating the surface at predetermined frequencies and amplitudes.

Abstract: Indicia having a requirement for a high degree of precision is printed onto a sheet and is scanned or read automatically shortly thereafter. Electronic control signals result from a comparison of the actually printed indicia with a pre-defined quality standard, and are used selectively to adjust command control signals to the printer to correct indicia printed thereafter. The leading edge of sheets to which the indicia is to be printed is precisely located by a light absorption detection or sensing mechanism which controls a sheet advance motor. The indicia printed, preferably bar code, is read by an optical bar code scanner traversing the printed code.

Abstract: Peanuts, almonds, Brazil nuts, hazelnuts and similar hard, dry roastable nuts with raisins or currants or both are maintained stable at granular sizes from 015 to 120 screen sizes. Raisins or currants or both are wetted in a heated liquid having the substantial effect of removing surface sugars and oils. The raisins, currants or both are treated further either by simultaneously wetting in the presence of flaxseeds or by pressing to a damp-dry state. The raisins, currants or both are mixed with a hard, dry roasted nut before granulating into from 015 to 120 screen sizes.

Abstract: A gravity fed water bath process treats waste water from spray rinses containing compounds of copper and like heavy metals. For displacing heavy metals, such as copper, the bath has a substantially pure metal with an electrode potential greater than the heavy metal contained in the rinse water. A system for controlling the pH level of the water bath treatment and for supplying acid at the beginning of the bath, and alkaline material at the bath's end provides a highly acidic pH level for the water bath and heavy metal removal chamber, and adjusts the pH level of the discharged water for satisfactory deposit in municipal sewer systems.A method for displacing the heavy metal from the compound in solution requires exposing the heavy metal compound to a substantially pure metal having an electrode potential greater than the heavy metal of the compound, in an acidic bath whose pH level is controlled.

Abstract: Organizations are disclosed for driving bit lines of a two-line 21/2D coincident current magnetic core memory in which a bit line not used for reading a bit out of a core is placed physically in parallel with the bit line driven by half select current to approximate in the unused line the capacitive and inductive coupling of the driven line with the word drive line. That coupling produces in the unused line the same noise (crosstalk) produced in the driven bit line by the word drive pulse. The crosstalk signal in the unused line is subtracted from the signal in the driven bit line before amplification and detection. The unused line may be a separate dummy line, or simply another bit line not being used for the bit being read out. In the case of paired bit lines used for common mode rejection of the bit drive signal, a second pair of unused bit lines is arranged in parallel for crosstalk cancellation.

Abstract: A variable speed controller for an alternating current induction motor reestablishes the start time for firing pulses and clock pulses in a circuit having a uniform frequency generator generating firing and clock pulses. Feedback from the stator terminals sets an oscillator with a sawtooth type ramp output. Subsequent feedback from the stator terminals are compared with the output of the oscillator in a comparator that establishes a time or phase shift in the generated output having the same frequency, for resetting the firing pulses so that the frequency of current to the stator winding is a function of the relationship between the stator and rotor positions, and of the current amplitude in the stator windings. Adjustment of the circuit parameters reduces the difference between the rotor and stator positions and optimizes stator current to maintain flux balance.

Abstract: A beam emitter type speed sensor for railroad rolling stock is calibrated by positioning an endless belt between rails of the track for the railroad rolling stock. The endless belt has a speed which is controllable. The endless belt is so positioned so that the railroad rolling stock can maneuver the speed sensor in proximity thereover having an antenna-to-belt distance comparable to the antenna-to-roadbed distance. A method of calibrating the indicator in the cab includes rotating the belt at a known speed.

Abstract: In a large scale addressable memory which is addressed with an applied block and word address, an auxiliary memory stores word addresses of defective locations within each block of the main memory. Such defective location addresses are supplied by the auxiliary memory in response to the applied block address. A set of comparators compare the applied word address and the defective location word addresses and signal any match. The auxiliary memory also provides a substitute location address for each stored defective location address. When a match is found by a comparator, the corresponding substitute location address is provided to the main memory to access a substitute memory location, which is known to be good.

Abstract: A computer-aided health care system for use by a paramedic. Findings taken from the patient by the paramedic are assigned numerical codes by use of preprinted forms. The paramedic uses a keyboard to enter the numerical codes into a fixed purpose computer. The computer compares the findings with a number of disease definitions stored in its memory. The computer then operates a printer to list numerical codes for all treatments to be administered. The paramedic uses these codes to enter a treatment and diagnostic manual which gives the name of the disease and specific instructions for its treatment, in the language of the paramedic.

Abstract: Strung rackets for hitting compressible balls have a stringing network that can be adapted to provide for an expanded sweetspot; precise diminution of dead spots especially at the top of the racket; reduced string wear; controllable areal stiffness for hard hitting; prolonged dwell time of the ball on the racket for directional control of the ball; and increased frictional contact between ball and racket for improved stroking, and application and control of spin to the ball. The rackets employ predetermined patterns and concentrations of string in predetermined areas within the racket frame to provide stringing networks complemental and functional to the particular characteristics of an individual player. Downwardly flared string crossings and multiple strand reentrant string crossings are used alone and in combination to provide the predetermined patterns and concentrations.

Abstract: An electronically programmable oscillator has a plurality of digitally incremented selectable frequency signal outputs, providing a wide range of incrementally distinguishable, selectable frequencies having defined pulse widths. Incremental frequency selection is made through delay lines and bypassable interpolating delay lines connected in series. Selectable bypassable delay loops can be inserted into the oscillator signal path by manually controlled electronic, programmable selections. The width and shape of the pulse is regulated at several stages of the circuit, using solid state electronic components.
