Abstract: PROGRAMMABLE STEERING CONTROL  APPARATUS FOR MOTOR VEHICLES                     ABSTRACT      Programmable motor vehicle steering control apparatus, which enables zero settings of front wheel caster, camber, toe-in and steering axis inclination, comprises left and right pairs of first and second, tangentially loaded helical spring elements and means for connecting the left pair of spring elements between a left front wheel steering arm and tie rod and the right pair of spring elements between a right front wheel steering arm and tie rod.  Parallel connecting arms of each second spring element cross so that when either pair of spring elements in push or pull loaded during vehicle turns, the two spring elements in each pair act in opposite, spring coil opening or closing directions.  The connecting means includes means for offsetting outboard ends of the spring elements in each pair and preloading means are provided for selectively preloading each of the spring elements.  Together, the offsetting means and preloading means cooperate to enable non-symmetrical spring element loading and unloading in vehicle turns to provide, for example, greater spring restoring forces on outside wheels in a turn, according to required steering control and wheel return-to-center characteristics.

Abstract: 27                  48,895 ABSTRACT OF THE DISCLOSURE     Electrical apparatus and more particularly vacuum electrical circuit breaker apparatus is taught. The electrical apparatus has a cylindrical movable terminal stem which is to be interconnected with a fixed terminal by way of a flexible conductor which is nevertheless relatively stiff and self supporting.  This is accomplished by using interlayered elongated rectangular plates or sheets between the two aforementioned terminals.  Connec-tion to the circular stem is made by utilizing offset tabs around the periphery of a central hole at one end of each of the sheets.  The offset allows the tabbed opening to be inserted over the stem.  After which the tabs are sandwiched or compressed to lie in the plane of the sheet thus causing the edges of the tab to flow around the stem reducing contact resistance.  Because there are multiple sheets in each flexible conductor packet, the number of three point contacts between the flexible conductors and the stem is increased.

Abstract: ABSTRACT OF THE INVENTION         METHODS OF AND APPARATUS FOR CONVERTING PULSE-AMPLITUDE-MODULATED SIGNALS INTO PULSE-CODE-MODULATED SIGNALS           A method of and apparatus for converting pulse-amplitude-modulated signals into PCM-signals in accordance with an approximated logarithmic characteristic curve.          In this process a partial coding characteristic curve which possesses a substantially reduced dynamic scope is firstly produced in known manner, and a second pre-decision is then carried out which sub-divides the dynamic region of the partial coding characteristic curves (TC) into two sub-regions in such manner that the coding of the lower and upper sub-region is effected with the same number of weighing steps.  Thus, in contrast to the known method, the proposed method requires one weighing step less.            (Figure 1).

Abstract: RANGE SURFACE UNIT RECEPTACLE                 ABSTRACT OF THE DISCLOSURE          The spadelike terminal pins of a conventional plug-in surface heating element for a domestic range of the elec-tric type are received in a socket member hingedly mounted to the range by a clip structure including a spring-biased pin joint.  The clip structure allows the heating element, nor-mally nested within and supported by a drip pan, to be tilted upwardly and then unplugged from the socket to permit ready removal of the drip pan for cleaning purposes.  Spring-biasing of the clip structure aids in retaining the heating element at its normal position within the drip pan.  The spring-biased pin joint is shielded from the radiant heat generated by the heating element to minimize the deteriorat-ing effects of repeated thermal expansion and contraction cycles.

Abstract: ABSTRACT OF THE DISCLOSURE         A process for producing corrugating medium pulp, fuel, and other products from a wide variety of woody materials is disclosed.  In one embodiment a pulping solution is pro-duced by cooking green chips in a water solution of mono-ethanolamine and subsequently collecting the liquor produced.          Pulp is then produced by digesting chips under a vapor dome of the pulping solution, or cooking the chips in the solution and subsequently digesting under a vapor dome.  Digested chips are then refined in pulping solution to produce corrugated medium pulp.  In another emboidment, fuel may be produced by digesting woody material under a vapor dome with sulfur dioxide and ammonia.  The digested chips then yield a lignin containing liquor which has a good fuel value and may be used as a liquid fuel or impregnate for woody material.  In another embodiment the pulping solution is used as a hard wood conversion resin.          Wood is impregnated and pressed.  The pressed wood may have a density of twice the original wood.  Monoethanolamine vapor also can convert soft wood to hard wood.  When wood is vapor impregnated under a vapor dome it may be pressed to a more dense configuration.  In both hard wood embodiments the pressed wood maintains its pressed configuration so that it may be used in construction or as a fuel.

Abstract: Abstract of the Disclosure A control system is provided for a combine or other vehicle having an engine for driving both the ground wheels of the vehicle and at least one auxiliary mechanism, such as the crop-processing mechanisms of a combine.  The engine is coupled to the ground wheels through a hydrostatic trans-mission and the power takeoff for the auxiliary mechanism is located on the engine side of the transmission.  A speed droop governor regulates the fuel input to the engine in response to changes in the engine speed.  Transmission control means adjusts the setting of the hydrostatic transmission, and thus the load applied to the engine via the transmission, in response to changes in engine speed or another parameter that varies with engine load so as to control the speed changes effected by the droop governor, The combined effect of the speed droop governor and the transmission control means is to gradually reduce the operating speed of the engine as the fuel input to the engine is increased, with the total speed reduction over the full load range of the engine comprising from about 1% to about 5% of the no-load speed.

Abstract: ABSTRACT GENETIC ENGINEERING It has been a problem to find an alternative, less time-consuming, and more reliable source of factor IX, a polypeptide which is essential to the human blood clotting process and necessary for the treatment of patients with Christmas disease. The invention is an important step towards solving the problem by way of genetic engineering, in that it provides recombinant DNA containing a DNA sequence occurring in the human factor IX genome. It includes recombinant DNA comprising substantially the whole sequence of human factor IX genome inserted in a cloning vehicle and transformed into a host such as E.coli.  It is conveniently characterised by a 129 or 203- nucleotide long sequence (J-J' and J'-J" in Figure 9).  Other fragments of the sequence have also been cloned and the invention includes DNA molecules comprising part or all of the human factor IX DNA. The invention also includes cDNA derived from human factor IX RNA. Uses of the invention include the provision of an intermediate of value in the genetic engineering of a factor IX polypeptide precursor and thence manufacture of the factor IX polypeptide, and in making probes for use in diagnosing the presence of normal or abnormal factor IX DNA in patients with Christmas disease.
