IPC: C07C51/25
Filed: 1994-06-03
Granted: 1996-06-01
Abstract: By the oxidation of olefins having 16 to 70 C atoms by means of chromosulphuric acid in a single- or multi-stage process in at least one reactor having a narrow residence time spectrum, carboxylic acid mixtures can be produced. These can be processed with monoalcohols or polyols such as glycol, glycerol, trimethylolpropane, pentaerythritol or sorbitol to give esters and partial esters or to give mixtures of such esters. By reaction with basic oxides or metal hydroxides, the corresponding soaps of the carboxylic acids can be produced by direct reaction or by reprecipitation. By reaction with amines or aminoalcohols the amides, amido esters and amino esters are obtained.   These products are distinguished by a pale colour, good heat stability and a wide application spectrum. <IMAGE>

Title: Power amplifier with clipping level control
Inventor: JACK C SONDERMEYER
IPC: H03G7/00
Filed: 1994-12-08
Granted: 1995-07-21
Abstract: In a power amplifier, a control device employing a dual ganged potentiometer is connected in the feedback circuits of successive amplifier stages to increase the gain of the front end stage while simultaneously reducing the gain in a subsequent stage when the control is turned down. A distortion circuit, such as a tube compression circuit, is coupled between the stages. When the control is turned down, the compression circuit is activated at a lower level that effectively reduces the output power of the second stage. Presence and resonance controls may be provided to tailor high and low frequency damping factor of the second stage and function until the compression circuitry is activated. A ripple reduction filter is provided in a filtered supply for the drivers in the second or power amplifier stage.

Title: Cantilever bicycle brake
Inventor: CAL M PHILLIPS
IPC: B62L1/06
Filed: 1996-03-22
Granted: 1997-02-11
Abstract: A cantilever bicycle brake having a piston 9 slidably mounted in a vertical central bore 54 in each brake arm. A standard pad stem 39 is mounted horizontally through the piston. The piston slides vertically for vertical adjustment, and rotates for toe adjustment. The toe can be fixed or floating. The vertical and toe settings are only needed once. They need not be reset after pad replacement. For constant-angle pad motion, a cylinder 6 is journalled horizontally through the brake arm parallel to the arm pivot axis 4. The pad stem is mounted horizontally diametrally through the cylinder, allowing the pad to pivot in the plane of arm motion. A generally horizontal linear guide 16 is fixed on the vehicle frame. The pad mount cylinder is coupled to the linear guide to maintain a constant pivot angle of the cylinder as the arms move, resulting in a constant angle of the pad. The piston and cylinder can be combined to provide true linear pad motion, as follows: The piston freely slides vertically in the brake arm. The cylinder is journalled through the piston, causing the piston to follow the linear path of the guide, rather than the arc of the arm, providing linear motion to the pad.
