Abstract: ABSTRACT OF THE DISCLOSURE     An adjustable plastic rack is provided for hanging articles. The rack includes at least a first pair of equally sized first and second members adjacent to one another, with the second member having at least an aperture therethrough and the first member having a pin at one end integral with the first member, the pin being pivotably engaged within the aperture with the opposite end of the pin protruding through the aperture.  At least one hook member is provided having fastening means integral with the hook member to fasten the hook member to the opposite end of the pin.  This action fastens the second member to the first member.  The hook member, the pin and the aperture define a pin joint, pivotable to attach the first member to the second member.  Such construction results in an inexpensive adjustable rack which can be advantageously formed from injection molded plastic and which can be assembled in a short amount of time without the use of special tools.

Abstract: ABSTRACT        A pressure responsive, variable resistance, analog device has at least one pair of first and second conductors in spaced-apart relationship.  A pressure sensitive resistive conductor composition is disposed in a position to interconnect a resistance between the first and second conductors when the resistive conductor composition makes contact with the conductors.  The amount of resistance so interconnected varies inversely to the amount of pressure exerted against the resistive composition.  The invention may be incorporated as part of a multiple touch switch having either a lateral or vertical configuration.  In addition, the invention may be configured as a pressure transducer device with or without a spacer between adjacent components of the device.

Abstract: Abstract of the Disclosure A motorcycle frame and suspension system employing a backbone frame member extending rearwardly over an engine and then downwardly where it is associated with an inverted U-shaped center frame.  Two pivot mechanisms for a rear fork are positioned in line with the ends of the inverted U-shape center frame and a cushion member is located therebetween.  The cushion member is linked at its first end with the middle of the center frame and at its second end to a linkage mechanism fixed to move with the upward pivotal motion of the rear fork.  The mechanism is so proportioned as to provide an increasing rate of upward motion to the cushion members as the rear fork moves upwardly.  The two pivot mechanisms are not identical, one allowing axial sliding movement and the other not allowing such movement.

Abstract: ABSTRACT OF THE DISCLOSURE:     The use of a liquor ratio which is as short as possible is of prime importance in the development of novel dyeing methods, in line with the necessity of saving energy and water in textile finishing.       Inventive considerations have shown that the defined object can be realized in the course of wet-treating textile ropes in jet dyeing machines if the tex-tile goods are driven by means of a non-inert gas stream and the dyestuff or product formulations necessary for carrying out the type of treatment desired are brought into contact with the goods by atomization into the cir-culated gaseous driving agent.       It is possible, on this basis, to make do with liquor ratios which are shorter than those of procedures hitherto conventional in the textile industry.

Abstract: ABSTRACT:            The invention relates to a bi-axial support of a rotatable body in a projectile for supporting said body such that it can perform small tilting motions about two mutually perpendicular axes lying in a plane, which is perpendicular to the longitudinal axis of the projectile.     The support consists of a spherical or partly spherical bearing body introduced into a correspondingly spherical cup-shaped recess in a projectile-fixed part having the open end directed forwards in the motion direction of the projectile.  The spherical bearing body is retained in the recess by means of two pairs of link arms defining two virtual tilting axes for the bearing body and connected to two output shafts such that a tilting motion of the body about the respective virtual axis results in a rotation of the respective output shaft and vice versa.  When firing the projectile the spherical surface of the bearing body comes in metallic contact with the spherical surface of the recess, whereby the support can withstand very high acceleration forces in any direction.

Abstract: TREATMENT OF LEWIS BASE CONTAINING POLYMERS TO IMPROVE ANTISTATIC, HYGROSCOPIC AND DYE RECEPTIVE PROPERTIES                 Abstract of the Disclosure A method is provided for treating and modifying solid, high molecular weight Lewis base containing polymers, particularly shaped structures such as fibers, filaments or knitted fabrics, to form branched polymer with improved electrical conductivity, water absorbency and dye receptivity while retaining the essential struc-tural shape.  The method comprises heating the polymer in the presence of an aqueous treating solution contain-ing an ethylenically unsaturated monomer which does not readily polymerize under the conditions of treatment and a catalyst which is a source of hydrogen ions or protons.  The treatment is carried out at a temperature and for a sufficient time so as to effect essentially single molecule addition of the monomer pendent to the polymer chain with substantial-ly no graft polymerization of the monomer to the polymer.          A particularly preferred embodiment of the method is the treatment of nylon 6,6 knitted fabric with an aqueous solution of acrylamide and hydrochloric acid for about one hour at 95°C to 100°C.

Abstract: Abstract of Disclosure A demodulator of the type employed in a "zero-IF" system uses a local oscillator for providing quadra-ture output signals at the center frequency of an FM sig-nal to be demodulated.  The demodulator has first and second mixers for separately mixing the FM signal with the quadrature signals to provide a first and second out-put signal each in quadrature at the outputs of said mixers. These signals are low pass filtered.  The demodulator in-cludes third and fourth mixers with each mixer receiving at an input one of the low pass signals.  At another in-put the mixers receive third and fourth signals.  The third and fourth signals are derived from mixing a variable controlled oscillator (VCO) signal with the local oscilla-tor quadrature signals.  The outputs of the third and fourth mixers are applied to the inputs of a difference amplifiers, the output of which controls the frequency of the VCO in an automatic frequency control mode (AFC) to cause the output of the difference amplifier to provide demodulated signal.          A switching means operates to alternate the third and fourth signals as applied to the input of the third and fourth means as well as the output as applied to the difference amplifier to cause an additional ampli-fier coupled to the outputs of the mixers to provide a DC control signal used for automatic gain control.

Abstract: ABSTRACT                 LOW NOISE CCD OUTPUT      The invention processes two signals having the same information content and having opposite noise-versus-frequency characteristics, to provide an output signal having said information content with reduced noise.  In a particular use of the invention, the signals are derived from a CCD imager 14.  In that case, one of the two signals may be a signal derived from a drain diffusion (28) in the form of a signal current and applied to an amplifier (40) which has a poor high frequency signal-to-noise ratio due to needed high frequency peaking, while the other signal may be derived from a floating diffusion (24) (or floating gate) through an on-chip MOSFET amplifier which has a poor low frequency signal-to-noise ratio due to 1/f noise.  The two output signals are filtered through complementary low-pass and high-pass filters (52/62, 62/52) respectively, and then combined together.
