Title: Method of controlling a transport means and a transport means for effecting the method
Inventor: VAENNINMAJA PEKKA

Abstract: Abstract A transport means (1) comprising a body (2) and sev-eral wheels (3a to 3h) positioned in the longitudinal direction one after another on both sides of the body and  turnable  about  vertical  axes  (4a  to  4h).  The transport means (1) is supported at one end turnably by means of a tractor means (6) by means of which the direction of travel of the transport means (1) is con-trolled.  In order that the transport means could be controlled more easily, a control sensor (7) is mount-ed in a swing joint (5) connecting the transport means (1) to the tractor means (6), which control sensor in-dicates the angle (.alpha.) of turning between the tractor means  (6)  and the transport means  (1), whereby the sensor (7) together with an adjusting means (8) con-trols the turning of the wheels (3a to 3h) in propor-tion to the angle  (.alpha.) of turning. When the angle (.alpha.) of turning is, e.g., no more than 20°, the ad-justing means (8) controls the wheels (3a to 3h) so that they turn in such a way that the transport means (1) turns about a centre (9) of turning positioned in the  middle  thereof  in  the  longitudinal  direction, whereby the turning radii at the front and rear end are substantially equal. When the angle (.alpha.) of turn-ing  exceeds 20°, the position of the centre (9) of turning is shifted in the longitudinal direction of the transport means (1) in proportion to the value of the angle (.alpha.) of turning towards the rear end of the transport means (1), whereby in parking situations it behaves similarly as a conventional trailer, but the axes of all the wheels  (3a to 3h) go through  the centre  (9)  of  turning,  whereby  the  wheels  always rotate without sliding.

Abstract: METHOD AND APPARATUS FOR GENERATING VIDEO SIGNALS           ABSTRACT OF THE DISCLOSURE A video signal generator employs a host processor subsystem (11), display controller system (18), display generator subsystem (20), refresh memory subsystem (24), and video data system (28) to process pixel data in parallel to achieve high pixel frequency rates permitting large flicker-free images. To achieve high pixel frequencies, parallel processing is maintained from the bit map memory  (36) until the data is processed by the digital-to-analog converter (DAC) (54). The display generator subsystem (20) outputs a multi-bit digital data address signal (35) which is used to address a plurality of bit map memory (BMM) arrays (36). The BMM arrays (36) operate in parallel, and the data (35) is read into a portion of each BMM array (37, 39) until the array (37, 39) is filled. The data is read out of the arrays (37, 39) in parallel (32) and into a plurality of BMM output multiplexers (MOM) (38), new data continuously being read into each BMM array (37, 39). The MOM (38) time division multiplexes the data signal (32) into data nibbles (26), of fewer bits,representing the color intensity of the data signals (32). The data nibbles (26)are multiplexed by a plurality of video multiplexers (40) to produce a multi-bitcolor intensity code (44) which is used to address a plurality of color look-up tables (CLUTs) (40). The CLUTs (40) select the array data for display, and generate color codes (48). The color codes (48) are multiplexed to the desired pixel frequency rate and are input into DACs (54) to drive a monitor (58).

Abstract: PRODUCT PUMP SYSTEM                     Inventor: Robert D. Heyl ABSTRACT OF THE DISCLOSURE           A dust-free,  vented arrangement comprising a self-contained filter dump station combined with a compressed gas product pump for conveying dry free-flowing material.  The filter dump station is for receiving the dry free-flowing particulate material which has been transported in a bag or drum or the like and is emptied through a grate in the apparatus into a hopper. Dust-laden air produced by this process is communicated to a filter section where that air passes through filter media for collection  of  the  dust  particles  and  is exhausted  to  the atmosphere. The filter media are cleaned by jets of pressurized gas removing the dust particles therefrom, and the dust particles are allowed to drop into the hopper.  The hopper serves to feed the material into the product pump.   The product pump has a product chamber, a product receiving inlet communicating with the product chamber, a product discharge outlet communicating with the  product  chamber,  and  a  pressurized  gas  inlet  also communicating with the product chamber.  A receiving inlet valve is connected to the product receiving inlet for regulating the flow of product through the product receiving inlet into the product chamber.  A pressurized gas inlet valve is connected to the pressurized gas inlet for regulating the flow of compressed gas into the product chamber.  The pressurized gas inlet means includes upper and lower inlets.  The upper inlet is positioned so that the pressurized gas passing through it generally impacts the upper portion of the product in the product chamber when filled and also pressurizes the product chamber.  The lower inlet is positioned so that the pressurized gas passing through it sweeps the product on the floor of  the product chamber out through the product discharge outlet.  A vent communicates with the product chamber and serves to permit venting of the product chamber after the product in the chamber has bean discharged out through the product discharge outlet and after the inlet valve has closed the pressurized gas inlet.   A venting line valve regulates the flow of gas from said product chamber out through the vent.  The vent line may communicate with the filter section of the dump station so that the vented discharge is filtered and any product carried therewith if salvaged.

Abstract: A method of removing heavy metals, particularly cadmium, from wet-process phosphoric acid produced by digesting raw phosphoric material with sulphuric acid, by precipitating out the heavy metals in sulphide form. The residual sulphuric acid is removed first by neutralization with alkali or as a not-readily dissolved sulphate precipitate. Alkali is added to obtain an Me/P ratio within the range of about 0.05-0.3, where Me is the number of catio equivalents in the alkali and P is the number of phosphorous atoms in the phosphoric acid, whereafter the heavy metals are precipitated out by adding a sulphide compound which is soluble in the phosphoric acid, and the sulphide precipitate removed.

Abstract: This lock comprises handling members which may be actuated according to a code, and a rack which may be displaced after actuating the actuating members controlled according to the code. Each actuating member cooperates with an insertion part which comprises at least a recess and which may be brought into two different positions. The insertion parts arranged according to the code prevent, in their start position, the displacement of the rack and, in their working position given by the cooperating actuating member, they allow the displacement of the rack owing to their recess or recesses. The insertion parts, which are not arranged according to the code, operate inversely. Thus, there is no resiliency difference between the coded and non coded actuating members and it is not possible to determine the code by groping.
