Abstract: A process for manufacturing gallium arsenide microwave circuits makes use of a nonphotosensitive acid resist (3) as an adhesive for holding the "front side" of a gallium arsenide wafer (1) onto a substrat (2) while operations such as etching "via holes" into the wafer )1) are being performed on the "back side" of the wafer (1). The process comprises front side processing, spinning the nonphotosensitive acid resist (3) onto the front-­side of the GaAs wafer (1), baking the protective acid resist coating onto the wafer (1), spinning the acid resist onto a substrate (2), joining the wafer (1) to the substrate (2), thinning the wafer (1), and performing backside processing.

Abstract: Concentrated sulfuric acid (3) (i.e., above about 70 weight percent and preferably above 93 weight percent) is used to cool hot sulfur combustion products. In addition, water and some of the sulfur oxides are removed from the gas stream. The hot sulfur combustion products enter (1) a contacting device (A), such as a cooling tower, where they come in contact with cool sulfuric acid. The gases exit (2) the tower cooled and dry. The strong sulfuric acid which is fed to the contacting device is heated up by contacting the sulfur combustion gases. In addition, the effluent acid concentration will be somewhat less than that fed due to water absorbed. Some of the hot acid is purged (7) from the strong acid circulating system while a make-up of more concentrated acid (8) is added so that the desired acid concentration can be maintained. The acid is then fed to a cooling device (B) prior to introduction back into the contacting device.

Abstract: In a method for manufacturing a sealing ring with a sealing lip, the material forming the sealing lip is fabricated in plastically deformable condition into the shape of a column-like hollow body. Prior to solidification, the column-like hollow body is twisted between axially spaced cross-sectional planes. This forms return elements with hydrodynamic action. Subsequently, the hollow body is solidfied and its diameter is enlarged axially outside the region of the sealing lip and it is then secured in a sealing ring housing.

Abstract: A fluid control valve (88) for controlling the flow of hydraulic fluid at a high pressure from a primary pump (50) and the flow of the hydraulic fluid at a low charge pressure from a charge pump (62) to cam-lobe type hydraulic motors (12) which are used to assist in driving a vehicle. When energizing the motors, charge pressure is first delivered to the motors. Thereafter, all of the supply and return lines (94, 96) leading to the motors (12) and to the primary pump (50) and the charge pump (62) are connected together to further increase the pressure delivered to the motors. Finally, the charge pressure line (72) is disconnected and the supply and return lines (94, 96) leading to the motors are connected to the high pressure supply and return lines (52, 54) leading to the primary pump. When the supply and return lines leading to the motors are disconnected from the primary pump, the lines leading to the motors are drained into a reservoir. An accumulator is provided within the motors to absorb sudden pressure delivered thereto. The flow of charge pressure fluid which controls the shifting of the spool is restricted by an orifice to control the rate of shifting and to provide sufficient time for gradually introducing the high pressure to the motors.

Abstract: An improved printing member (18) is disclosed for use in a system wherein a current source (1), in combination with a resistive ribbon (14), produces heating in selected areas (14a) of the ribbon for effecting the formation of a printing pattern on the printing member, which member is composed of a first layer (22), having a predetermined melt­ing temperature, and a heat-conducting layer (20) which adheres to the first layer below its predetermined melting temperature and which adheres to said resistive ribbon at temperatures above said predetermined melting temperature, such that, when the second layer is heated to a temperature level above the predetermined melting temperature in selected areas forming a pattern to be printed, the select­ed areas will adhere to the resistive ribbon and release from the first layer. Consequently, when the resistive ribbon is in contact with the heat-conductive layer while at a temperature level above the predetermined melting temperature of the first layer and is then drawn away from the heat-conductive layer, the selected areas will be removed from the heat-conductive layer forming the pattern to be printed therein.

Abstract: The invention refers to the mixing of gas or gases, with air, in a controllable ratio, by means of a mixing apparatus wherein the entrance air is forced in a complete developed rotation stream, by which a strong suction pressure is created in the centre, so that gas can be sucked in ratio independent of the total volume per second. 
     The mixing ratio of gas and air is controlled through an adjustable angle of the air entrance nozzles (3). The rotating airstream is accelerated in the radial entrance plane and via a logarithmic curved profile, the airstream is guided in the axial outlet direction of the mixing apparatus. The rotating airstream develops a centre-core stream, where inside it a maximal under-pressure is created. By this underpressure, the main gasstream can be sucked and mixed with the airstream via the whirl grates (24), which are fixed in the outletsection just in front of the mixture outlet valve (25,26).
