The bag is made from an unsupported and unreinforced thin plastic material that is substantially incapable of safely supporting the weight load of the bottles from a single thickness area of the bag material. In the package the bag has two substantially stretched and tensioned areas. One of the areas is a band about the body portion of the bottles. The other area is a band that includes gathered and secured material, part of which is a handle. The two stretched and tensioned band areas of the bag cooperate together and with the bottles to firmly hold the bottles together and enable the weight load of the bottles to be safely and securely carried from the handle.

Abstract: Abstract of the Disclosure A method of producing diagnostic test strips for detecting given components present in biological liquids, which strips comprise a solid support medium carrying at least two reagents for effecting a given color test reaction on wetting contact with a liquid analysate.  A water-insoluble support medium chemically inert to reagent inks is successively printed with a multitude of dots of each reagent ink so as to thereby form at least two separate patterns of printed dots, the reagent ink dots of each pattern being dried after printing and being arranged in closely spaced relationship with one another and with the dots of each different pattern, so that the printed dots of each reagent ink are separately arranged between the dots of each different reagent ink without contacting the dots of different inks, and the reagents in the respective dry dots are thereby kept separate from one another, while allowing said reagents to diffuse along the surface of the support medium to mutually interact thereon in the presence of liquid analysate.  After printing, the sheet may be cut up into a plurality of test strips of desired shape and size.

Abstract: ABSTRACT OF THE DISCLOSURE     A closed loop waste treatment and water recycling system that includes a delivery system, an anoxic reactor, an aerobic digestion chamber, a filtering system, an adsorption system, a disinfecting system and a water return system.  The delivery system includes one or more flush-type toilets and urinals which receive flush water from the water return system and deliver the toilet and urinal waste and flush water to the anoxic reactor.  The anoxic reactor contains bacteria which utilize organics in the toilet waste to convert oxi-dized nitrogen compounds, such as nitrates, to nitrogen gas, produce bicarbonates and other products.  The bacteria, in accomplishing this, lower the organic load on subsequent processes.  A denitrified liquid containing bicarbonates and reduced amounts of organics is transferred to the aerobic digestion chamber, which contains bio-logically active solids and in which organic carbon, organic nitro-gen, and ammonium compounds are oxidized by bacteria to obtain a liquid product high in concentration of oxidized nitrogen compounds such as nitrates and low in soluble carbonaceous compounds.  This liquid product is filtered, treated with activated carbon, disinfec-ted, and subsequently returned to the toilets and urinals as color-less, clear and odorless flush water containing oxidized nitrogen compounds such as nitrates.  The oxidized nitrogen compounds pro-duced in the aerobic digestion chamber insure prevention of odors in the system.  As a result of the effective management of nitrogen in the system, it can be made of reasonable size, undesirable odors are avoided and a desired slower buildup of solids in the system is achieved.

Abstract: ABSTRACT OF THE DISCLOSURE       A closed loop idle speed controller for a fuel injection system operates to control an air valve which controls an air passage bypassing the main air flow.  The air valve is positioned by an actuator whose output position is controlled by fuel pressure operating against a spring.           The fuel pressure is controlled by a pair of solenoid-operated on-off valves, one of which responds to electrical signals representing engine speeds below a speed reference to direct fuel to the actuator and the other of which responds to signals representing speeds above the reference to permit fuel to be withdrawn from the actuator and returned to its source.  Each of the solenoid on-off valves is supplied from a pulse width modulator.  The engine-driven distributor provides pulses responsive to engine speed which are connected to a sample and hold circuit.  The sample and hold circuit provides d.c. voltage levels proportional to engine rpm, modified with changes in engine coolant temperature, to a pair of summing amplifiers which compare the modified speed voltage with an idle speed reference voltage to produce speed error signals. Underspeed signals are connected to the pulse width modulator connected to the supply solenoid on-off valve and overspeed signals to the modulator connected to the return solenoid on-off valve.  Certain auxiliary circuits provide for modified operation during starting, during hot starts, during closed throttle operation, or during deceleration with a manual transmission car.

Abstract: U.S. 846,697 ABSTRACT OF THE DISCLOSURE   A circuit for inverting a DC voltage to an AC voltage having a predetermined waveform, includes first and second level shifing stages for providing selectively at their respective output terminals a voltage having the level of the DC voltage, or about twice the level of the DC voltage.  A first pair of transistorized switches are included for concurrently and selectively connecting the output terminal of one of the level shifters to one end of a load, and ground to the other end, respectively, for driving current through the load in a particular direction and obtaining a desired level and polarity of voltage thereacross, or the switches are operated to ground both ends of the load.  In generating a stepwise approximation of a symmetrical AC waveform, such as a sinewave, one level shifting stage is charging from the DC voltage supply while the other level shifting stage is discharging into the load, during each half-cycle of the AC voltage.  A second pair of transistorized (or mechanical) switches are added for selectively connecting each one of the first pair of transistorized switches in parallel with a transistorized switch of each one of the first and second level shifting stages, respectively, for operating the waveform synthesizer at half-rated voltage, and twice-rated current.  Also included is a control signal generator for operating the switches and level shifting stages in a manner providing in combination concurrent dynamic level shifting and pulse width modulation in synthesizing a desired AC waveform.

Abstract: ABSTRACT     This invention relates to an apparatus and method for detecting and measuring the position of a fracture in solid formations, such as for example a grout filled borehole.  An electrical element is placed the length of the borehole prior to filling the hole with grout.  When the hole is filled and the grout solidified, any fracture in the grout also breaks the electrical element.  The element is constructed such that its electrical capacitance is a known function of its length.          The element is constructed of easily frangible materials so that it is severed in close proximity to the grout fracture.          The capacitance of the element after the fracture can be measured using suitable instrumentation.  The position of the break is a function of the capacitance as measured after the break.

Abstract: Abstract of the Disclosure An automatic sewing machine is provided wherein the clamps for holding the workpiece can be used to define at least two different sewing patterns. The sewing pattern which is particularly defined by a given arrangement of clamps is indicated to a digital control system within the sewing machine. The control system is operative to subsequently implement an automated stitching of the particular sewing pattern which has thus been indicated thereto. This automatic stitching is accomplished through a sequential reading of a set of instructions previously stored within a memory associated with the control system. The set of instructions remain the same for at least two different sewing patterns. These instructions are altered upon read out by certain control logic which takes note of which pattern has been defined by the given arrangement of clamps.          The automated stitching is completed by an automatic ejection of the clamped workpiece.
