Abstract: ABSTRACT A composition of material for use as a friction material in a brake and its method of manufacture. Liquid double salts of dibasic and monobasic (ammonium-potassium hydrogen) phosphoric acid (DSP) is added to a dry mixture of reinforcing fiber, friction modifiers, fillers and phenolic resin to create a high viscosity slurry.  Thereafter, a metallic (magnesium) oxide and para formaldehyde (para) are added to the slurry.  Molds which have been previously heated are filled with the slurry and any excess removed.  The metallic oxide reacts with the DSP and the para reacts with the phenolic resin to create a two binder matrix for holding the reinforcing fiber, friction material and fillers in a fixed relationship corresponding to the shape of a brake pad. The brake pads are removed from the molds and transported to a ventilated chamber where the internal curing proceeds at or near ambient temperature to complete the manufacture of the brake pad.

Abstract: THERMOELECTRIC COOLER Abstract of the Disclosure A  thermoelectric  cooler  (10)  having  a  storage compartment (36) with insulated inside walls forming an access opening on one side opposite a back wall (42a) of substantially the same size includes an insulated door (40)  movable  between  a  closed  position  sealing  said access opening and an open position displaced from one edge of the access opening for providing direct access to the interior of said storage compartment over the entire area of  the access opening.  The  insulated door  (40) comprises a pair of door segments pivotally interconnect-ed about a median axis in parallel with one edge of the access  opening  of  the  storage  compartment.   An over-center spring  (68)  is interconnected between the door segments to exert a resilient biasing force tending to pivot the door segments in one direction about the hinge (58) axis when the spring is on one side thereof and an opposite  direction  when the  spring  is  moved  to  the opposite side of the median axis.  A guide (76, 80, 82) and follower  system is  provided  adjacent  the  storage compartment  interacting  with  the  door  segments  for guiding the door segments in coplanar alignment while the spring is on one side of the median axis and as the door approaches the closed position.  When the door is moved toward the open position the spring moves to the other side  of  the median axis  and pivots  one  of  the  door segments  away  from  the  coplanar  position  towards  an angularly  transverse  position  so  that  a  minimum  of adjacent space (38) is required even though the door is fully displaced to provide access over the entire area of the access opening.

Abstract: METHOD AND APPARATUS FOR ALIGNING A DIRECTIONAL ANTENNA TO RECEIVE SIGNALS FROM ONE OR MORE GEOSTATIONARY SATELLITES     ABSTRACT OF THE DISCLOSURE          An  alignment  apparatus  and method for using it to orient  a  directional antenna so as to receive signals   broadcast  from  one  or  more  geostationary satellites.    In one embodiment, suitable for aligning an  antenna  to  receive  a  signal  from just a single satellite,  the  antenna's  elevation  angle  is  first adjusted to a desired value and the antenna then turned in azimuth in a generally horizontal plane until the signal is received.  To correct for a turn plane that is not precisely horizontal, the step of adjusting the longitudinal elevation angle is intermittently repeated  during  the  step  of  turning.   In a second embodiment,  suitable  for  aligning an antenna that is rotatable  about  the  axis of a polar mount to receive signals   from   any   selected  one  of  a  number  of satellites,  the  method  further  includes preliminary steps   of   controllably  adjusting  to  predetermined angles  both  the  elevation angle of the polar mount's axis  and  the  elevation  angle of the antenna itself, when  rotated  to  its zenith.  Thereafter, the antenna is  rotated about the polar mount axis to the elevation angle  of  a  predetermined  satellite, and the antenna turned in azimuth in the generally horizontal plane until   a   signal  from  the  satellite  is  received. Rotation  about  the  polar  mount  axis  then  permits selective   reception   of  signals  from  any  visible geostationary satellite.

Abstract: ABSTRACT OF THE DISCLOSURE           A neutral position indicator for an electrically conductive cable coiled in an automotive steering wheel includes a fixed storage case for storing the electrically conductive cable therein, the storage case including a rotatable member rotatable with the steering wheel, and a position indicator unit rotatably mounted in the fixed storage case and angularly movable for a first angular interval each time the rotatable member rotates through a second angular interval in response to completion of the rotation of the rotatable member through the second angular interval, the position indicator unit being indicative of a neutral position of the electrically conductive cable when the position indicator unit reaches a prescribed angular position.  The storage case is covered with a cover having a window for allowing visual observation of the position indicator unit. The angular position of the rotatable member, i.e., the electrically conductive cable coiled in the storage case, can be indicated by the position indicator unit since the position indicator unit is angularly moved through the first angular extent each time the rotatable member rotates through the second angular extent.  The neutral position of the cable can easily be confirmed by visually checking the angular position of the position indicator unit through the window.   Total p.13

Abstract: Abstract of the disclosure The invention comprises a mass spectrometer adapted for the determination of isotopic ratios which has several ion-collecting means disposed along its mass focal plane.  Separate current amplifier means  are provided for each ion collecting means and comprise an electrometer amplifying element and an input resistor disposed in an inner box, itself disposed within a sealed evacuated housing.  Means are provided for cooling the amplifier element to a temperature substantially below 20°C. Means are provided for maintaining the temperature of at least the input resistor substantially constant. Cooling the amplifier element, typically to between 0 and 5°C, results in an unexpected reduction in low frequency noise which allows the time required to determine an isotope ratio to be  reduced, thereby substantially increasing sample throughout.
