Abstract: ABSTRACT OF THE DISCLOSURE    An improved input circuit for an electronic vehicle speed control unit is disclosed.   An ignition current sensor coil is adapted to have a voltage differential signal induced therein each time an ignition pulse is generated by the vehicle engine.  Electrical noise signals generated by the vehicle engine appear as common mode signals across the ignition current sensor coil.  The ignition current sensor coil is connected at each end to a capacitor, both of which are connected to ground potential. The ends of the ignition current sensor coil are further connected to the inputs of a differential amplifier. The capacitors appear in a series loop with the ignition current sensor coil for the differential voltage signals and consequently, provide tuning for inductance.  However, the capacitors appear in parallel with one another to ground potential with respect to the common mode noise signals, thereby providing high frequency noise rejection for the input circuit.  The differential amplifier further rejects the common mode noise signal applied to the inputs thereof.

Abstract: Abstract Of The Disclosure OCCULT FECAL BLOOD TEST SLIDE    AND MANUFACTURING METHOD           A test slide for conducting a test for occult blood in feces is fabricated with a sheet of filter paper or other reagent carrier material impregnated with a test reagent and packaged in an envelope enclosure which overlies both sides of the reagent carrier sheet.  One or more specimen apertures are provided in the enclosure on one side of the reagent carrier sheet to permit the placement of feces specimens on the reagent carrier sheet through the apertures.  On the other side, the enclosure is openable to form a test opening (which encompasses the feces specimens) so that a developing reagent can be applied to the other side of the reagent carrier sheet at the location of the specimens.  A barrier material, impervious to the passage of liquids, is deposited on the reagent carrier sheet in a line which runs across the area of the test opening.  This line of barrier material isolates a portion of the reagent carrier sheet from the specimen areas, preventing the migration of liquids from the specimen area to the isolated area.  A line of positive test material is deposited on the reagent carrier sheet in the isolated area to function as a positive test of the operability of the test slide.  The barrier prevents contamination of the specimens by the positive test material.  In the fabrication of a test slide of this type, the line of barrier material and the line of positive test material are preferably deposited in a single pass of the reagent carrier material from roll stock.

Abstract: (57) ABSTRACT OF THE DISCLOSURE            This invention relates to a method for generating real-time control parameters by means of a video camera for smoke-generating combustion reactions.  In accordance with the method, a video camera (12) is used for obtaining a video signal, which is digitized and filtered temporally and spatial-ly.  According to the invention, the digitized video signal is divided on the basis of its signal level distribution into signal subareas to reduce the quantity of processed informa-tion; the picture elements belonging to the same subarea are combined into contiguous image areas representing a certain signal level, the subareas are combined into an integrated image, subsequent images are averaged to eliminate random disturbance, and the averaged image is displayed on a display device.  The method in accordance with the invention facili-tates the real-time monitoring of a combustion process.

Abstract: The invention relates to a method for producing lead having a sulphur content beneath about 2%, from sulphur-containing oxidic lead raw materials contaminated with zinc and/or other readily oxidized elements, by smelting the materials in afurnace in which furnace contents can be agitated. When practicing the method, the lead raw materials are charged to the furnace together with iron-containing fluxes and solid reduction agents. The charged materials are heated under agitation, to form a lead phase and a slag phase. The amount of reduction agent charged is selected so that at least all the lead contained in the furnace is reduced to lead metal and the amount and composition of the fluxes are selected so that a terminal slag is obtained in which the sum of the iron and zinc present is 30-40%, and so that the slag has a content of 15-25% of both Si0<sub>2</sub> and CaO + MgO.Lead raw materials, fluxes and reduction agents are suitably introduced in a plurality of charges, with intermediate moderate heating, prior to commencing the smelting process.

Abstract: A process for preparing potato fibres, and potato fibres which are prepared in accordance with the process. According to the process, the potatoes 1 are washed 2 and finely divided 3 into fruit juice, starch and pulp, with the starch 8 subsequently being separated 4 from the fruit juice and the pulp 5. The process is characterized in that solid impurities are removed 6 from the pulp, the fruit juice is effervesced 9 and added to the pulp 5 in order to form a pulp/fruit juice mixture 10, which is purified from solid impurities by means of density separation. Subsequently, the pulp 11 is dewatered in order to move some of the fruit juice and the dewatered pulp is refined 12 such that the content of fruit juice and dissolved salts in the pulp is reduced by the pulp being prepressed 13 to a dry matter content of 20-30% and then washed 14 by adding water in order to obtain a dry matter content of 11-16%, after which the pulp is pressed finely 15 to a dry matter content of 20-30%. In conclusion, the refined pulp is dried 16 and ground 17 in order to obtain the final potato fibre product 20.

Abstract: Reciprocating floor conveyor floor members (28) are moved by hydraulic cylinders (1, 2, 3) which are slightly tilted so as to exert a vertical component of force onto the ends of longitudinal drive beams (128, 130, 132) to which the cylinders (1, 2, 3) are connected. These beams (128, 130, 132) are made from tubular stock. Each is guided by a pair of longitudinally spaced apart bearings. Each bearing is a part of a bearing assembly (128, 130) which depends from an upper central portion of a transverse truss (80, 82). Each longitudinal drive member (128, 130, 132) is welded to a transverse drive beam (10, 12, 14) by fillet welds on each side of the longitudinal drive tube (128, 130, 132). Each such drive tube (128, 130, 132) is stiffened in the region of the weld by a short tubular insert which is rammed into the drive tube. The floor members (28) of the conveyor run on plastic slide bearings (26) which are snap fitted onto longitudinal guide beams (22). The guide beams (22) are small in size and are welded on both sides to transverse support beams (24). The construction of the slide bearings (26) permits the use of large dimension, strong, undressed fillet welds. The slide bearings (26) include wing portions (68) on each side which abut similar wing portions (68) on sideways adjacent bearings (26). The floor members (28) are held vertically relative to the bearings (26) by the engagement of bottom flanges (36, 38) within side slots (72) formed in the bearings (26). The floor members (28) add strength and stiffness to the bearings (26) and the abutting contact of the wing portions (68) causes the bearings (26) to mutually brace each other.

The arrangement is so designed that in any particular application, the rim M at most just barely comes into contact with the expansion sleeve (1) so avoiding uselessly and detrimentally loading the spacer S.
