Abstract: Abstract of the Disclosure The present invention is a remotely actuated battery pow-ered, auxiliary pressurizing system for hydraulically actuated lift arm devices which system is driven independently of the principal power source of the vehicle on which the hydraulic lift arm device may be mounted but utilizes the same hydraulic control system as when the system is being pressurized by the vehicle engine.  The invention includes radio or light means to activate the battery powered unit from the working basket or platform without the use of electrical conduits or pneumatic or hydraulic actuation lines within the lift arms and without in any way interfering with the conventional lift arms control system established in the working basket or platform.  The remotely actuated battery powered pres-surizing system is mounted on the chassis of the vehicle and com-prises a battery operated motor pump assembly, control means for the motor pump assembly which latter includes a receiver for the signals transmitted thereto by the actuator on the work platform by radio waves or light rays.  Provision is also made for actuating the system without reliance upon the transmission from the work platform, for operating accessories and in event of emergency.

Abstract: MACHINE FOR CLINCHING A MULTIPLE        LEAD COMPONENT      Abstract of the Disclosure A clinching machine for clinching the leads of a connector on a circuit board includes a top wall which provides a work surface having an opening for receiving the leads and a clamp for clamping the circuit board and the connector in place against the work surface.  A pair of clinching jaws, each having a pair of work faces intersecting at an angle of less than 90°, are pivotably mounted in fixed relationship adjacent to the opening.  Pneumatic actuators first cause the clamp to engage the circuit board and the connector, and then cause the jaws to pivot, thereby drawing the leads into close contact with land areas on the circuit board.  The amount of rotation of the jaws corresponds to the difference between the intersecting angle and 90°.

Abstract: ABSTRACT An apparatus for feeding individual pieces of timber from a mat of a plurality of interconnected or closely adjacent timber pieces, comprises a feed conveyor for feeding the timber mat through a feed path which, for example, may comprise an inclined plane along which the timber mat moves by gravity.  A cam or arm member is oscillated periodically to engage in front of the fore-most edge of the foremost piece of the timber mat in order to position it at a location in which it will be engaged by a respective projection member which forms a part of an endless conveyor having a plurality of such projection members which are advantageously formed by pivoting them together.  The projection members are shaped in a tri-angular fashion so that the apex of the triangular part engages directly adjacent the trailing edge of the fore-most piece of lumber which is fed along the feed path and it aids in separating this piece from the remaining pieces. In addition, the projection member  includes a support surface which is inclined downwardly in the direction of movement of the transfer conveyor and the supporting surf-ace moves below each timber piece in succession and supports it in a downwardly and forwardly inclined position as it is tranferred away from the feedconveyor.  The transfer conveyor moves through a path such that the foremost edge of each picked-up lumber piece is deposited on a second conveyor which also may be of an endless belt type which travels through a path intersecting the transfer conveyor.

Abstract: METHOD FOR SUBSTANTIALLY COMPLETE REMOVAL  OF HYDROGEN SULFIDE FROM SULFUR BEARING              INDUSTRIAL GASES                      Abstract of the Invention Hydrogen sulfide is substantially completely removed from a sulfur bearing industrial gas stream by absorbing the H2S into a liquid absorbent, stripping the absorbent of absorbed H2S and reacting it with SO2 in a ratio of H2S/SO2 greater than the stoichiometric ratio of 2.0:1.0 to produce elemental sulfur and water, leaving a tall gas containing an excess of hydrogen sulfide but no sulfur dioxide.  At least the last stage of the reaction is carried out in a liquid reaction medium at a temperature not i greater than 160° C.  The excess H2S assures complete reduction at these temperatures of all SO2 to elemental sulfur.  The remaining excess H2S is then recycled in the tall gas back into the original industrial gas stream prior to the point of contact of the industrial gas stream with the liquid absorbing solution.

Abstract: TURBINE-CONDENSER SUPPORT SYSTEM               ABSTRACT OF THE DISCLOSURE         A subatmospheric pressure condenser has an en-closure within which steam is condensed after exhausting from an associated turbine.  The enclosure is flexibly con-nected to the turbine to permit relative movement there-between.  The condenser also has an outer wall which is flexibly connected to the enclosure to define a vacuum balancing chamber therebetween with the outer wall being structurally connected to the turbine for the purpose of reducing the atmospheric pressure force exerted on the turbine's structure by the turbine. The structural connec-tors between the outer wall and the turbine intersect the enclosure and provide fluid communication therethrough between the turbine's exhaust port and the vacuum balancing chamber.  At the intersection between the structural con-nectors and the enclosure, sleeves are attached to the enclosure in closely spaced surrounding relationship with each of the structural connectors to minimize liquid intru-sion therebetween from the enclosure to the vacuum balancing chamber.  Since the outer wall is flexibly connected to the enclosure and the vacuum balancing chamber has little or no water intrusion, the outer wall efficiently transmits atmos-pheric pressure forces exerted thereon through the struc-tural connectors to the turbine and reduce the load on and thus the required size of the turbine's support structure.          The sleeve members which fit about the structural connectors permit relative movement therebetween and extend a prede-termined distance from the enclosure to further minimize water leakage into and subsequent accumulation thereof in the vacuum balancing chamber.
