Abstract: ABSTRACT OF THE DISCLOSURE     Wheeled, dual axle device having a platform which is supported by an axle arrangement which provides a mechanical action for engaging and disengaging a brake when force or weight is applied to the platform/or the platform is tilted from a predetermined position.  At least one wheel is mounted on a wheel bearing axle and the load receiving platform is mounted on a load bearing axle.          An upright connects the load and wheel bearing axles and is free to pivot relative to the axes of both axles.  When weight is applied to the platform and the wheel is placed in contact with the resisting element, the upright rotates relative to the of the load and wheel bearing axles until it reaches an equilibrium position.  Thereafter, the upright tends to remain in the equilibrium position notwithstanding rotation of the load receiving platform about the axis of the load bearing axle.  Brake means are actuated in response to the rotation movement of the load receiving platform while the upright remains in the equilibrium position.  If the upright is moved from the equilibrium position, force is generated by the upright as it attempts to restore itself under the influence of the weight to the equilibrium position.  This force is used to operate the brake mechanism.  In the preferred embodiment, an axially expanding brake mechanism is sensitive to the amount of weight on the platform and the degree of tilt of the 1.     platform.  Upon engagement of the brake, thee rotating wheel mounted brake pad cooperates with the axially expanding brake mechanism to cause the upright to tend to move or create a force that increases the braking force in one direction of rotation (self-energizing braking) and decreases the braking force in the opposite direction of rotation.  The de-acceleration force produced by braking also tends to influence the upright to move or decrease a force so as to control the self-energizing braking action to prevent brake lock-up.

Abstract: ABSTRACT OF THE DISCLOSURE          A pollution control system and method in which sulfur oxides in flue gases are adsorbed by activated char in a gas-solid contacting device.  The saturated char is regenerated in an integrated desorption-reduction vessel, to which crushed coal and combustion-supporting air are supplied.          A portion of the crushed coal is burned to provide the heat for the regeneration of the char, resulting in the formation of sulfur dioxide and carbon dioxide gases, and the chemical consumption of a portion of the char.  The remaining crushed coal reduces the sulfur dioxide to gaseous sulfur, and results in a material having a porous system suitable for use in the adsorption of sulfur oxides.  The remaining re-generated char and the oxidized coal are cycled back to the gas-solid contacting device, and the gaseous sulfur is condensed to liquid in a condenser.

Abstract: ABSTRACT OF THE INVENTION         An oil well instrumentation system for measuring the pressure and temperature at various depths during drill stem tests.  The measurements may be hydrodynamically analyzed to map the geological structure of an oil field in order to sel-ect drilling locations.  The measurements may also be utilized to calculate properties of an existing oil well such as total production and optimum production rate and to determine the geologic properties of the structure in which the well is drilled such as porocity.  The system includes a pressure sensor, a temperature sensor and a microprocessor based device receiving the outputs of the press; e and temperature sensors for displaying ??d recording periodic measurements.  The dis-play and recording device is powered by a rechargeable bat-tery, and the condition of the battery is internally monitored and an indication of its condition is displayed.  Oil well measurements are relatively short in duration, but they are normally made over a relatively long period of time so that a substantial period of time elapses between measurements.  In order to preserve the life of the battery between rechargings, the display and recording device is placed in a quiescent mode between measurements in which power is removed from most of the internal components including the microprocessor.

The striker has a tail portion located in a power cylinder which is joined to the housing and is filled with a fluid medium under pressure said fluid medium operating the striker.  Provision is made of an arresting mechanism which is kinematically connected to a drive designed to engage the striker for effecting its back-ward stroke in the process of which the fluid medium under pressure is compressed, storing potential energy.  According to the invention, the striker backward stroke drive is constructed in the form of several hydraulic cylinders equidistantly spaced round the periphery of the housing. The rod of each of the hyd-raulic cylinders is connected to the striker arresting mechanism. One of the spaces in said hydraulic cylinders is constantly connected with the interior space of the power cylinder for the purpose of moving the arresting mechanism under the pressure of the fluid medium, whereas the other  cylinder space is periodically put in communication with the pressure source, in order to effect the backward stroke of the arresting mechanism together with the striker, and with a pressure medium exhaust line.

Abstract: Abstract An improved RF amplifier system in which an undesired frequency such as the image frequency is rejected.      The amplifier circuit includes a first tank circuit tuned to a first predetermined frequency by a first voltage variable capacitor and a second tank circuit tuned to a second frequency by a second voltage variable capacitor.  A dual gate FET is coupled to the tank circuits such that the drain of the FET is across the first tank circuit and the source is connected across the second tank circuit.  The second tank circuit is tuned to the image frequency or the undesired frequency while the first tank circuit is tuned to the desired frequency.  When the image or undesired frequency is received the drain tank impedance of the FET becomes very small while the source tank impedance is relatively large which effectively degenerates the amplifier gain at the image frequency.  When this occurs the current flowing into the first tank circuit is reduced causing the voltage appearing across the drain to become reduced and the undesired signals to be rejected in the IF section of the receiver.
