Abstract: PROTECTIVE CIRCUIT FOR SELECTIVELY APPLYING POWER TO A MOTOR    ABSTRACT OF THE DISCLOSURE       A protective circuit is described for selectively applying power to a motor.  The circuit includes a power switch which closes and opens to apply and remove power from the motor, and a control for diverting reactively inducted motor current from the power switch back to the motor via a current path when the power switch is opened.  The control opens the current path when the power switch opens and remains open for a predetermined interval so that, when the motor is unenergized and mechanically rotated, the motor is not braked by current flow through the current path and the motor.

Abstract: ABSTRACT OF THE DISCLOSURE                    An improved transmitter for a compatible indepen-dent sideband (ISB) AM stereo system developes a phase modulated carrier where the modulation represents the stereo difference signal inverse modulated by the stereo sum signal in accordance with a selected modulation function.  The phase modulated carrier then is amplitude modulated by the stereo sum signal.  This simplified modulation scheme provides the second-harmonic sideband correction required to develop a true single sideband type signal wherein left and right stereo information are transmitted in separate lower and upper sidebands, which can be demodulated without distortion in ISB AM stereo receivers.  Simplified receivers which use inverse modulation are also disclosed.

Abstract: ABSTRACT OF THE DISCLOSURE:     A method and apparatus for chemical analysis of specimens in order to detect the presence and percentages of given chemical elements (C, N, H, S and O) therein.  Said specimen is subjected to known chemical treatments in order to reveal said elements, which are detected and revealed as peaks of a curve traced by the apparatus, each peak corresponding to an analyzed and detected elements.  The surface area of each element peak is then correlated with that of the other element peaks in order to obtain a series of ratios between said areas.  Such ratios are then compared, for each element pairs, with an experimentally determined graph which is valable for each element pair in all specimens and gives a ratio between the numbers of atoms of said element pair, so that from said ratios between the numbers of atoms of all analyzed and detected elements, a reduced formula of the specimen composition may be obtained.  When the specimen is weighened, besides said reduced formula, it is possible to statistically locate a probable composition of the specimen molecule residual, as formed by not analyzed and detected elements.

Abstract: ABSTRACT OF THE DISCLOSURE     A time recorder for recording the working times of individuals during successive work periods includes devices for detecting faulty use of identifying elements associated with the individuals for operating the recorder.  Upon such a faulty use being detected a blocking device is activated to prevent recordal of time for the relevant work period in respect of the particular individual's identifying element.  The devices for detecting faulty use of the identifying elements are monitoring devices com-prising signal generators with the aid of which a faulty use of an identifying element can be indicated and stored.  The blocking devices are automatically actuable to release the working time storage devices for each new work period.

Abstract: ABSTRACT A method of winning copper, and accompanying metals, from sulfidic ores, post-flotation residues and waste products from the pyrometallurgical processing of copper ores.  The insoluble minerals of the metals are trans-fered into solution consists by leaching the above materials, initially ground to below 0.1 mm particle size, by means of a mixture of a heterocyclic aromatic amine, preferably pyridine, and a chlorinated hydrocarbon of C1 to C3 chain length, preferably of a protic nature as chloroform.  The liquid phase is separated from the solid residue, and the metal compounds are separated from the solution and deposited by known methods, e.g. by electro-deposition.  The leaching process is preferably performed at the boiling temperature of the solvent mixture, the solvents being recycled to the process, preferably after purification by known methods.

A router base assembly includes handles and a flat base plate and is adjustably fixed to the housing.  The flat plate supports the router for movement along a work surface and is provided with a central opening through which the router bit extends to engage and penetrate the work surface.  The other end of the housing has a support surface upon which the router can rest when the router is temporarily put down during use and when it is stored, or while the bit is changed, or while the base assembly is adjusted relative to the housing for depth adjustment of the bit.  A switch is provided on the housing for turning the router motor "on" and "off," and is controlled by a switch operator having a portion which extends through an opening in the router housing support surface.  The switch operator has one portion which extends beyond the support surface when the electric motor is "on," and is positioned flush with that surface when the motor is "off" so that the motor is "off" and cannot be turned "on" when the router is supported on its support surface.  The switch operator has another portion rigidly connected to the one portion and which is at the side of the router housing and close to one of the handles for turning the motor "on" and "off."

Abstract: Abstract of the Disclosure A carbon composite article and the method of making the article wherein selected carbon fibrous materials are formed into a basic starting substrate having a volume greater than the desired volume of the' finished article.  Very small amounts of a carbonaceous-binder material are used to bond the fibrous materials together at a multiplicity of bonding sites.  The basic substrate is then subjected to controlled temperatures and pressures to form a shaped substrate characterized by having a high degree of open porosity, a predetermined shape and structural integrity sufficient to withstand subsequent substrate processing  The carbonaceous binder is applied to the fibrous material in a manner whereby substantial encapsulation of the individual fibers is avoided so that the portions of the fibers disposed inter-mediate the bonding sites are free to move to accomodate and effectively distribute stresses which may be generated within the substrate due to material shrinkage or other process related causes.  The shaped substrate is then partially or fully densified in a freestanding config-uration by chemical vapor deposition of pyrolytic materials interstitially of the substrate.

Abstract: LITHIUM PEROXIDE PRIMARY ELEMENT     ABSTRACT OF THE DISCLOSURE   In a galvanic primary element of the system Li/H2O2, the aqueous cathode depolariser H2O2 is fixated as a polyurethane gel.  It can thereby be controlled and caused to react with the anode metal in accordance with the current drain requirements.  This is accomplished using a ram to press the gel toward a conductor which covers the lithium anode, which may take the form of a metal grid and/or a gas diffusion electrode.  The oxygen which forms in the working layer through catalytic decomposition of hydrogen per-oxide creates a gas bubble when the current is interrupted or the ram is stopped, thereby interrupting the further supply of hydrogen peroxide to the catalyst.

The installation includes a first heat exchanger for collecting heat having a high heat value, the heat exchanger being disposed within a solar collector.  A medium is provided for receiving heat collected in the first heat exchanger.  A second heat exchanger is provided for collecting heat having a lower heat value with respect to the first heat exchanger. A circulator pump is provided for circulating the medium through the first heat exchanger and the second heat exchanger, the circulator pump being a prime mover driven by a pressure difference between the first heat exchanger and the second heat exchanger and being a charger pump.  The prime mover and charger pump operate as differential piston pumps having a common piston rod, each such piston pump being operatively disposed within a chamber in-cluding control ducts, which load, via fluidic connections, an auxiliary control slider member. The auxiliary control slider member is reciprocated within the chamber, and upon reaching end portions of the differential pis-ton, switches the chambers of the two differential piston pumps to effect oppositely directed movement.  Thus, the pump may be used to provide heat to a swimming pool, or to provide thermal drive for a refrigerator or an air conditioning system.
