Abstract: ABSTRACT OF THE DISCLOSURE     A face shield affixed to a safety helmet has a plurality of air vents formed therein in mutually spaced relation.  Each of the air vents has a movable closing member and is selectively openable and closable via the closing member.  Each of the air vents includes a slot, a raised cover over the slot spaced from the corresponding one of the helmet and face plate to form an opening, a pair of spaced parallel grooves formed in the cover on opposite sides of the opening and extending along the length of the opening and a closing member movably mounted in the grooves.  The closing member selectively opens and closes the opening to a desired extent when it is inserted in the grooves and provides air circulation in the helmet during hot weather to cool the helmet for the wearer and enhance his comfort, so that he is induced to continue wearing the helmet regardless of the heat and thereby protects himself from injury.

Granted: 1982-04-27
Abstract: FORMATION OF ELECTROSTATIC LATENT IMAGE ABSTRACT OF THE DISCLOSURE . Disclosed is a process for forming an electrostatic latent image on a recording element having a dielectric layer superposed on a conductive electrode. In the first step of this process, the recording element and a xerographic sensitive element having a photoconductive layer also superposed on a conductive electrode are charged with the same polarity. In the second step, the photosensitive element is brought into virtual contact with the recording element so that the charged surface of the photoconductive layer in the photosensitive element is in face-to-face relationship with the charged surface of the dielectric layer in the recording element. In the third step, an external voltage is imposed between the two conductive electrodes, said voltage being of at least a magnitude for producing an electric field causing breakdown of minute air-gaps present between the contacted surfaces of the photosensitive element and the recording element and, before the completion of the external voltage imposition, an optical image is projected onto the photoconductive layer in the photosensitive element. - 1 -

Abstract: METHOD AND APPARATUS FOR EXPANDING THE WIDTH OF PREFORMED FIBROUS WEBS            Abstract This invention is directed to a method and apparatus for expanding the width of preformed fibrous webs.  Fibrous webs having fibers oriented in their lengthwise direction can be widened by this method and this orientation is still maintained in the widened web.  The method involves feeding the web to a blade edge lying at an angle to the lengthwise direction, abruptly changing the direction of travel of the web at the edge from the lengthwise direction to a second direction, and turning the web fibers in the second direction while expanding the width of the web.  The profile of fibrous webs, i.e., the thickness, uniformity, weight and fiber density, across its width can also be changed and controlled according to the method disclosed.

Abstract: POSITION SURVEILLANCE USING ONE ACTIVE RANGING SATELLITE AND TIME OF ARRIVAL OF A SIGNAL FROM          AN INDEPENDENT SATELLITE        Abstract of the Disclosure The position of a ship or other object being located is determined at an earth station using an active ranging satellite and a satellite which transmits time signals. One line of position is determined by two-way active ranging through the first satellite. The other line of position is determined by one-way ranging from the second satellite. The time interval between the time of arrival of the timing signal at the ship and reception of the active ranging signal at the ship is measured and sent back to the earth station with the ship's active ranging response. The position fix is then computed at the earth station.

Abstract: ABSTRACT OF THE DISCLOSURE           This invention provides an apparatus for mounting, driving and steering the wheels of a high mobility wheeled vehicle, such as those used over roadless terrain in tree harvesting operations.  Each vehicle wheel is mounted on a rotatable hub which is in turn journaled on the end of a wheel drive housing.  The housing is medially pivoted to the wheel suspension structure of the vehicle for steering move-ments and has a driving motor mounted on the inner end of the housing and connected to the wheel hub through an appropriate gearing system.  The pivotal mounting of the drive housing is preferably located at the end of a walking beam arm which is disposed at a substantial horizontal angle with respect to the longitudinal axis of the vehicle to provide clearance for steering movements of the vehicle wheel.  The steering motion is imparted to the drive housing by an actuator which is connected between the inner end of the drive housing and the inner end of the walking beam arm.

Granted: 1981-11-03
Abstract: ABSTRACT     A lamp assembly and power module is provided for a microform display apparatus, such as a fanless microfiche reader.  The lamp assembly and power module are both situated in a drawer which is removably inserted into the base of the reader to form a air-restricted path for the efficient convection of heat away from the reader.  By setting the lamp at an angle to the longitudinal axis of the drawer, both the lamp assembly and power module components can fit in the drawer.  The front end of the drawer is provided with a grille for air passage, and a chimney structure is situated adjacent the rear of the drawer for the efficient evacuation of heat.          The lamp and power module are located below the chimney, and as the lamp and power module components heat the surrounding air, the air rises up the chimney and out of the reader by convection.  This air movement creates a draft through the grille in the front of the drawer, which serves to sufficient-ly cool the components.

Abstract: Abstract of the ???closure A double heterostructure laser having a pair of opposite-conductivity-type, wide bandgap cladding layers separated by a narrower bandgap active region is characterized in that the active region includes a low-loss waveguide layer and contiguous therewith a narrower bandgap active layer in the form of a narrow strip which extends along the longitudinal (resonator) axis of the laser. Suitable lateral current confinement means, such as reversed biased p-n junctions, are provided to constrain pumping current to flow in a narrow channel through the active layer. Lasers of this type exhibit relatively high pulsed power outputs (e.g., 400 mW), linear L-I characteristics, stable fundamental transverse mode and single longitudinal mode oscillation. In another embodiment the surfaces of the waveguide layer adjacent the active layer are provided with distributed feedback gratings. Also described are techniques for shaping the active layer without the introduction of debilitating defects therein, as well as procedures for LPE growth on Al-containing Group III-V compound layers which are exposed to processing in the ambient.

Abstract: ABSTRACT     Title:-   METHOD AND MEANS FOR CONTROLLING THE OPERATION OF           FLUIDISED BED COMBUSTION APPARATUS     The specification describes a method and means for controlling operation of a fluidised bed combustion apparatus.  In  the proposals embodied in the invention the supply of combustion air fed to the fluidised bed is augmented by inert gas (preferably waste gas taken from a low temperature outlet of the apparatus) and the proportion of inert gas used to augment the combustion supporting air is variable in dependence upon the temperature of the fluidised bed in the apparatus and/or the thermal demand placed upon the apparatus.  In described embodiments of means enabling the invention to be effected arrangements are described including a recycled gas    fan, coupled to the outlet for waste gas of the apparatus, for feeding waste gas to a mixer and the use of a two input mixer fan  coupled to both atmosphere and a waste gas supply line connected to a waste gas outlet.  The volume of waste gas supplied is controllable in dependence upon the temperature of the bed in the apparatus and/or the thermal demand placed on the apparatus.  The rate at which fuel is fed to the apparatus may also be controlled in dependence upon the thermal demand placed on the apparatus.

Abstract: ABSTRACT OF THE DISCLOSURE     An air-to-air heat exchanger, comprising an array of stain-less steel tubings arranged in a three-fold pass, is connected to the outlet of the combustion chamber of a liquid hydrocarbon-fueled, thermo-electric generator.  Air enters the heat exchanger at the ambient temperature and is pre-heated up to 500°C.  At the same time, the temperature of the gases leaving the combustion chamber is reduced from 700°C to only 200°C.  This pre-heating of the air reduces fuel consumption, increases efficiency and makes it more difficult to detect the generator by means of its infrared signature.
