Inventor: DYVIK F
IPC: C25C1/16

Abstract: The present invention relates to a method for manufacturing zinc hydrometallur­gically from zinc-containing starting materials. The method comprises one or more leaching stages, one or more solution purifying stages and one or more electrowinning stages for recovering metallic zinc from the leaching solution obtained. The method is operating with a closed solution circuit. A predeter­mined part volume of the solution obtained in the electrowinning stage or stages is withdrawn and concentrated by evaporation so as to precipitate any magne­sium and manganese present in the part volume in the form of metal salt crys­tals. The precipitated crystal mass is separated from the residual liquid phase. The liquid phase in this manner purified with respect to magnesium and manga­nese can be recycled to the leaching process or utilized for some other purpose. When the process is carried out in a sulphate environment, the solution obtained in the electrowinning stage or stages is concentrated to a sulphuric acid concen­tration of at least 60% by weight.The precipitated crystal mass, which has but a small volume, may be dumped to no disadvantage. In accordance with a preferred embodiment, the crystal mass is re-dissolved in a small quantity of water, thereby enabling practically all the zinc content to be recovered in metallic form, by electrowinning.

Abstract: Apparatus for controlling a vehicle suspension system includes acceleration sensors mounted on the vehicle for producing electrical signals representative of road surface undulations or irregularities, processing circuitry for processing the sensor signals to produce control signals, and a shock absorber or damper having adjustable damping characteristics. The damper preferably includes two chambers connected by a controllable bypass. One of the chambers becomes smaller during compression of the suspension system, and one becomes smaller during expansion. A controllable throttle and/or valve is provided in the bypass to adjust the damping characteristic of the absorber. The circuitry produces control signals H and w which are representative of the average height of the overall road surface undulations, and a ratio of average heights of long-wave and short-wave undulations, respectively. The circuitry further processes these signals to produce control signals F and P to control the bypass throttle and/or valve, respectively, in accordance with the following relationship: P=ao+a1H+a2w+a3Hw F=bo+b1H+b2w+b3Hw where, ao-a3 and bo-b3 are predetermined constants.

Abstract: An invalid hoist has a lifting arm, a sling hanger support mounted to turn about a rigid vertical bearing axis at the outer end of the arm and a sling hanger which is a unitary construction pivotable about a horizontal axis relative to the sling hanger support. The sling hanger presents spaced sling attachment points on both sides of the horizontal axis for connection of one pair of sling attachments to one side of the horizontal axis and for connection of a second pair of sling attachments to the opposite side of the horizontal axis. Thus the disposition of a sling-suspended invalid can be changed, while suspended on the hoist, by pivotal movement of the sling hanger about the horizontal axis.

Abstract: In an apparatus for binding loose sheets in one or more folders there is utilized a regulating circuit means where an inserted folder (F) interrupts a light beam to a photodiode (16) which simultaneously starts a time counter (18) and closes the power supply (via 31) to the heating plate (2), wherewith the binding operation is carried out. The time interval of the timing counter is determined in response to the actual values of the width of the folders and the starting temperature of the heating plate. These values are obtained from a width detector (34, 7, 35) and a temperature detector (28), said values being fed into a microcomputer (19) controlling the timer. When the timer has counted down the time interval to zero, it interrupts the power supply to the heating plate (via 31).

Abstract: An apparatus for an internal combustion engine controls engine timing as a function of engine load, speed and air intake temperature to reduce engine NOx emissions and/or engine fuel consumption. The apparatus is particularly beneficial to a large, aftercooled turbocharged engine which utilizes a cooling system having a liquid cooled, separate circuit aftercooler (SCAC) to cool the pressurized intake air. By routing the aftercooler circuit and engine coolant circuit through a common or single core radiator, the aftercooler cooling circuit temperature and associated engine air intake temperature are reduced to further reduce engine NOx emissions and/or engine fuel consumption.

Abstract: Hinges (12) for orthopedic and rehabilitation braces allow intuitive, convenient and positive control and adjustment of the limits to which the braces (10) may extend or flex. Such hinges (12) also allow convenient locking of such braces (10). A flexion switch (24) and an extension switch (26) allow convenient repositioning of stops (56) or limits which limit flexion and extension of the brace (10). Such switches (24, 26) may be repositioned, however, only with repositioning pressure for moving the switch (24, 26) to a new position combined with safety pressure for unlocking the switch (24, 26). A brace locking switch may also be included. Such hinges (12) promote more effective post-operative and rehabilitation results because they, among other things, allow users easily to change the flexion, extension and fixation limitations of their braces (10) conveniently and in real time such as during post-operative and physical therapy sessions and workouts.

Abstract: In a code division multiple access communication system, a method and apparatus provide for an efficient testing of operating behavior of a quality indicator bit. The method and the accompanying apparatus include configuring a receiver to expect to receive a communication channel at a full data rate, and transmitting a signal from a transmitter to the receiver. The signal is carrying the communication channel at a data rate other than said full data rate, and at a power level for receiving at the full data rate. Consequently, the receiver fails to receive the communication channel at the full data rate. A received signal to noise ratio of the received signal at the receiver is determined. A value of the quality indicator bit is determined based on the determined signal to noise ratio. The determined value of the quality indicator bit is communicated to the transmitter.
