Abstract: ABSTRACT         A tape cassette and an apparatus for use with such a cassette. The cassette housing has openings in two opposite side walls, and contains a tape which is suited for recording purposes at both sides, passed from one hub over guide elements along a side wall, then crossing over substan-tially diagonally to a tape guide element near the diagonally opposed cor-ner, passed along the opposite sidewall and finally over a subsequent guide element to the other, counter-rotating winding hub.  The apparatus may be a tape recording or playback apparatus or be capable of both functions.  It has two counter rotating winding spindles, on which the cassette may be positioned, and a capstan and a recording and/or playback head are disposed at one side of the spindles and another capstan and recording and/or  play-back head disposed at the other side of the spindles so that each head can cooperate through the respective hole in the cassette with one side of the tape.

Abstract: ABSTRACT OF THE DISCLOSURE         Certain high strength alloys lacking resistance to hydrogen embrittlement are cold worked and heat treated utilizing critical pre-selected conditions to result in a unique alloy having increased resistance to hydrogen embrittlement without unacceptable loss of strength.  It is theorized that this unexpected improved resistance correlates with the concentration of certain elements, such as phosphorus and sulfur as impurities on the crystallographic boundary surfaces of the alloy.

Abstract: STRAIN RELIEF                            ABSTRACT            A strain relief for an electrical conductor cord is disclosed for distributing a bending stress acting on the cord.  The strain relief includes a head portion and a flexible tail portion molded about a conductor having a major transverse axis of greater dimension than its minor transverse axis.  A bending force acting on the cord in a direction to effect bending about a bend axis nonparallel to the major transverse axis of the cord induces both bending and torsional movement of the strain relief so as to dis-tribute the flexure strain over the length of cord within the strain relief and thereby increase the flexure life of the cord.

Abstract: PREAMBLE TO DISCLOSURE     Be it known that JOSHUA SWITHENHANK and DAVID          SHAW TAYLOR of The Department of Fuel Technology, The University of Sheffield, St. George's Square, Sheffield 1, England, have made an invention entitled :                  "CONTROL OF BURNERS" the following disclosure contains a correct and full description of the invention and of the best mode known to the Inventors of taking advantage of the same.

Abstract: ABSTRACT OF THE DISCLOSURE A print hammer mechanism which forms a magnetic path between the opposite fixed and free ends of an elongated resilient hammer element using a permanent magnet, a first pole piece terminating in a pole tip adjacent the free end of the hammer element and electromagnetic means for cancelling the effects of the permanent magnet employs a second pole piece having a pole tip disposed adjacent the free end of the hammer element between the first pole piece and the fixed end of the hammer element.  The relatively short magnetic path of low reluctance along the hammer element between the pole pieces combines with the effect of flux flowing in two gaps perpendicular to the flat surface of the hammer element to significantly improve the mag-netic properties of the print hammer mechanism including the ability to quickly release and then retract the hammer element and the ability to increase the resonant frequency and/or the amount of energy stored in the hammer element for a given amount of magnetic flux available.  The second pole piece forms a gap with the hammer element when the hammer element is in a spring-loaded retract position against the first pole piece, providing better retraction of the hammer after release and reducing the amount of magnetic energy required to overcome the effects of the permanent magnet and release the hammer element.  The electromagnetic means for cancelling the effects of the permanent magnet consists of a coil wound about the first pole piece in direct contact therewith, enabling the first pole piece and adjacent parts of the magnetic circuit to provide adequate heat dissipat-ing without the need for fins or other heat dissipating elements on the coil.

Abstract: A process for the treatment of an-aluminum-salt slag produced in the remelting of aluminum by the addition of salt to aluminum scrap wherein the aluminum salt slag is sub-jected to pressure and impact rolling to a thickness of about 0.2 mm to about 1 mm and the product is milled to an X80 value of about 130 to 150 microns.  The milled product is classified in a plurality of stages to recover therefrom a large-particle  fraction consisting at least predominantly of aluminum partricles, and a fine-particle fraction.  The fine particle fraction is subjected to flotation in at least one flotation stage to which a base is added in an amount of 0.04 to 0.4 g of the base per ton of the material subjected to flotation to bring the pH to between 10 and 11, whereupon a cation active collector of the formula R0-(CH2)n-NH-(CH2)n--NH2 is added to recover an impurity-containing froth of low chloride level and a concentrate containing most of the chlorides of said slag.

Abstract: Abstract of the Disclosure A copper-nickel-silicon-chromium alloy having a high hardness and improved electrical conductivity.  The alloy is composed by weight of 2.0% to 3.0% nickel, 0.4% to 0.5% silicon, 0.1% to 0.5% chromium, and the balance copper.  The silicon is used in excess of the stoichiometric relationship wtih nickel to provide excess silicon, and the chromium is used in excess of the stoichiometric relationship with the excess silicon.          The alloy is heat treated by initially heating the alloy to a temperature in the range of 1600°F to 1800°F and is thereafter quenched.  The quenched alloy is then subjected to a two-step aging treatment in which the alloy is initially aged at a temperature of 482°C to 593°C to precipitate the metal silic-ides and develop a hardness in excess of 90 Rockwell B (185 Brinell) and subsequently is subjected to a second aging at a temperature in the range of 399°C to 482°C, which serves to precipitate the excess chromium from solution and increase the electrical conductivity to a value greater than 45%.

Abstract: ABSTRACT:           A power supply circuit for supplying current to a MOS depletion load transistor logic circuit for use in programmers for washing machines or controllers for tumble driers.  The power supply circuit comprises a depletion MOS transistor having its drain-source path connected between first and second power supply rails.  The conduc-tivity of the depletion transistor is controlled by a long tail pair amplifier which compares a reference voltage derived from a source with a voltage derived from the second supply rail using a voltage divider.  The voltage divider is constructed to compensate for the effects of process variations on parameters such as threshold volt-age and thereby hold the voltage divider ratio substant-ially constant.  The voltage divider comprises two enhance-ment MOS transistors connected in series between the second supply rail and ground and a current source in the form of a depletion MOS transistor and an enhancement transistor connected in series between the first and second supply rails.  The gates of all the transistors are connected to a junction of the current source transistor and the drain of the transistor connected thereto.  The voltage across the drain-source of this latter transistor varies with threshold voltage and is added to the voltage on the second rail.  Further  the voltage at the gates of the enhancement transistors of the voltage divider is used to vary their conductivity.
