Abstract: ADJUSTABLE ENERGY ABSORBING DEVICE                 PROVIDING LINEAR DECELERATION                   ABSTRACT OF THE DISCLOSURE     An adjustable kinetic energy absorbing device wherein a piston is moved in response to an applied impact force along within a tube defining a chamber containing hydraulic fluid.  The tube has a plurality of orifice openings, therein spaced therealong in the direction or movement of the piston, and an elongated path is defined outwardly of the chamber, preferably in the outer surface of the tube, and in fluid communication with the orifice openings.          The path is relatively narrow in width and extends along the tube.  An elongated flow control element is supported in the device and movable lengthwise along the path in response to manual operation of an adjustment assembly including a cam operatively engaging the elongated element.  The flow control element has formations spaced therealong adapted to register with the orifice openings to control flow of hydraulic fluid through the openings in response to movement of the element.  A region in the device in fluid communication with the path receives fluid flowing through the orifice openings and along the path in response to movement of the piston.

Abstract: ABSTRACT OF THE DISCLOSURE           A temperature-compensated band-gap reference of the type employing two transistors operated at different current densities to develop a positive TC current.  This current flows through a first resistor of nominal TC to develop a positive TC voltage which is connected in series with a negative TC voltage developed  by the base-to-emitter voltage of a transistor, to produce a composite temperature compensated output voltage.  The circuitry further includes a second resistor connected in series with the first resistor and having a positive TC to produce an additional compen-sating voltage having a temperature coefficient following a parabolic expression. This additional voltage, when connected with the other components of the output voltage, reduces the small residual inherent TC of the band-gap reference to provide a more table reference source.

Abstract: ABSTRACT OF THE DISCLOSURE          This invention relates to a process for the production of non-cellular polyurethane ureas elastomers using a chain-extender mixture produced from asymmetric-ally alkyl-substituted anilines by condensation with formaldehyde.  The chain-extending agents used in the instant invention show medium reactivity to compounds containing isocyanate groups.  These chain-extending agents may be processed both in high-pressure and in low-pressure metering and mixing units because they are either liquid at room temperature or can be melted at relatively low temperatures (below 55 °C).  The homogeneous, i.e. non-cellular, polyurethane urea elastomers obtained in the instant invention are distinguished by having excellent mechanical properties.

Abstract: Abstract of the Disclosure A reversible ratchet wrench handle in which the actuator for the direction reversing mechanism is located close to the portion of the handle that is grasped by the user.  This permits the user to operate the actuator with the thumb of the hand holding the handle whereby changing the direction of operation of the wrench is a one handed rather than a two handed operation.  Locating the actuator near the hand grip portion of the handle also removes it from the head of the handle, the usual location, and this allows the head to be made thinner for better access to narrow places.  The actuator for the direction reversing mechanism is a switch button that is movable back and forth axially of the wrench handle and this kind of movement insures more positive action.
