Title: Weight reduced brake rotor
Inventor: WINTER KLAUS
IPC: F16D65/12
Filed: 1991-09-25
Abstract: WEIGHT REDUCED BRAKE ROTOR          ABSTRACT OF THE DISCLOSURE         An improved disc brake rotor is formed with fins extending between the two annular braking members which are elongated tangentially of the rotor axis and disposed in two groups lying at different radial distances from the axis.  The tangential orientation of the fins minimizes the amount of material required to form the fins while achieving structural rigidity comparable to other fin arrangements which require substantially more material.  The fin arrangement disclosed thus enables a substantial reduction in weight and also achieves efficient cooling air flow patterns for either direction of rotation of the rotor.

Abstract: PHB 33.742                                     17.09.1992 ABSTRACT: Motion vector estimation, motion picture encoding and storage.     In the encoding of a frame (P3) in a digitised motion picture sequence, the frame is divided into blocks (A) of pixels and a motion vector (VA) found topredicts the contents of each block A from a block (A') in a previous frame (IO). Rather than evaluate many thousands of candidate vectors to find the best motion vector (VA), relatively few candidate vectors are evaluated, based on starting vector which is the estimated motion vector for a neighbouring block (LB(A)) in the same frame. To allow parallel processing of several pixel blocks, all the blocks of one row in the current frame are assigned to one processor (DSP), and a starting vector is obtained from a block (LB(A)) previously processed by the same processor. Further starting vectors are obtained if desired from neighbouring blocks (UR(B),DR(B)) in neighbouring frames of the sequence. The candidate vectors based on a starting vector may be very few in number, or may fill an area a few percent of the full search area. The method may favour candidate vectors which are more economical to encode.          (Figure 1)

Title: Constituent concentration indicator with a differentiator means and a signal conditioning means
Inventor: KIRK DAVID
IPC: G01N21/78
Filed: 1992-12-04
Abstract: ABSTRACT OF THE DISCLOSURE   The Constituent Concentration Indicator with a Differentiator or Means and a Signal Condition-ing Means detects the presence of a particular constituent in either a solid, liquid or gas and returns a rapid and accurate measurement of the concentration of the constituent. The Indicator is comprised of a sensor containing a stepper motor driven tape impregnated with a chemical substance reactive to a particular constituent. Discoloration of the tape occurs in the presence of the constituent and this discoloration is converted to an electrical signal which is indicative of the rate of change in the chemical reaction taking place and is linear for some portion of time. The signal is differentiated and the resultant differentiated signal is indicative of the arithmetic mean of a plurality of instantaneous values taken at intervals during the linear portion of the reaction. The extent of the reaction as evidenced by the level of the sensor output signal is continuously monitored and compared to a known value. If the sensor output signal exceeds that of the known value the differentiated signal is transferred to a display device, the stepper motor is activated and the sensor tape is advanced in preparation for the receipt of a fresh sample. The tape advances only if a reaction has occurred. Optionally, the sensor tape may be advanced at predetermined periodic intervals under the control of a timed override or, at any time, by a manual override.

IPC: F04D29/12
Filed: 1991-07-08
Abstract: A coolant pump system driven initially by an electric motor in-line with the pump shaft to the pump housing incorporates a ram air-assisted cooling system. The ram air-assisted cooling system includes an electric motor whose rotating shaft drives the primary fan member. A second fan member is located about and connected to the periphery of the primary fan member and is rotated by high velocity air streams purposefully directed at the secondary fan blades. The air which drives the secondary fan member is preferably gathered by one or more air inlet funnels. Typically, two air inlet funnels are equiangularly disposed adjacent the periphery of the secondary fan blade members so that a balanced current of air is swept across the secondary fan blades. A shroud extends over the secondary fan blade members to force the inlet air over the fan blade members.
