Patent EP-0385057-A1 (EP)
Title: Antiskid chain
Inventor: FRANKLIN CHARLES R
IPC: B60C27/10
Filed: 1990-01-03
Abstract: An anti-skid chain for a vehicle tire comprises an inner and outer harness. The outer side harness comprises a closed loop harness line with elastic expansion members acting as a damping elements. A locking device is attached at one end of the harness line and a tensioning chain at the other end passes through the locking device, which permits movement of the tensioning chain for tensioning and prevents movement in the opposite direction. The inner side harness comprises a ring-shaped resilient stirrup which can be elastically spread apart for slipping across the tire tread. Closure members on the free ends of the stirrup lock the stirrup closed on release of the stirrup.

Abstract: A broadcaster for flowable spreading material, especially fertilizer, consists of a supply container with at least one adjustable outflow orifice and with an outflow shaft adjoining this, from which the spreading material issues in the manner of a jet in a falling stream, and of a centrifugal disc rotating under this about an axis arranged offset relative to the outflow and having at least one throwblade which extends over the entire radial extent of the jet of spreading material to the circumference of the centrifugal disc and which, in cross-section, forms a U-profile fastened by its lower leg to the centrifugal disc. To reduce uncontrolled rebound losses, the outflow shaft and/or the upper leg of the throwblade are so designed and arranged that the particles reflected by rebound effects when the throwblade penetrates into the jet of spreading material are deflected into the throwblade or intercepted by this and accelerated outwards.

Abstract: The baling chamber (54) of one type of round baler is de­fined by belts (46) which are trained over rolls connected to a drive. Stones can enter the nip (90) formed between the belts (46) and some of the rolls, e.g. a lower front belt driving roll (20), and thereby cause poor tracking of the belts (46). 
     To reduce the problem, a shield device (92) is snap-fit mounted on the roll (20). The device (92) includes a nip bridging plate an upright portion (96) of which abuts the belt run (48) advancing to the nip (90) and a downwardly sloping lower portion (98) of which bridges the nip (90). Thus the device (92) covers the nip (90) preventing access to it by the stones, and stones which fall upon it slide down the sloping portion (98) of the plate eventually to find their way harmlessly to the ground.

Abstract: A sheet reversing apparatus comprises a support (31) on which sheets are stacked, an entrance section (10) for guiding the sheet to the support, a blowing mechanism (28) for directing an air stream to a sheet stack on the support to separate a lowermost sheet and the remaining sheets, and a feeding mechanism for attracting the sheet to feed it. Further, a stopper plate (37) is provided to be pivoted above the support so that it cooperates with the support to pinch and brake the sheet therebetween in a continuous reversing mode wherein the incoming sheet is fed as it is and that it abuts against the incoming sheet by a portion thereof opposing a leading end of the sheet in a stack reversing mode wherein while the sheets are being stacked the lowermost sheet is separated and fed.

Abstract: In an ECL circuit comprising a differential type switching circuit (12) having first and second output terminals, a first transistor (a pull-up transistor Q7) connected to a first power source (V1), a second transistor (a pull-down transistor Q5) transistor connected to a second power source (V2), and a capacitor (Cc) connected between the second output terminal of the switching circuit and the base of the second transistor, the ECL circuit further comprises a constant current source (I BIAS ) connected between the first power source and the base of the second transistor, and an impedance (2) connected between the base of the second transistor and the second power source. In the above ECL circuit, the base of the second transistor is biased by means of a circuit constituted by the constant current source and the impedance and the static current flowing in the second transistor can be stably maintained by using a constant current source which can be easily obtained in the prior art as the above constant current source. Further, since the base potential of the second transistor can be determined by the second power source potential of the constant current source, the power consumption can be reduced by adequately setting the second power source potential. In addition, since the base impedance of the second transistor can be set to be higher than the base impedance of the transistor Q5 in the conventional circuit shown in Fig. 1, charges injected into the base of the second transistor via the capacitor may effectively function, causing the driving ability of the second transistor to be enhanced.

Abstract: The rotating tabletting machine has a rotatably mounted die plate (2) provided with die bores (4). In the die plates (2) are guided upper punches (10) and lower punches, the position of which is controlled by means of vertically adjustable pressure rollers (6, 7). In order to reduce the time hitherto required for the disassembly of a pressing station because the essential components of a known pressing station had to be stripped down into their essential components for the purpose of cleaning or for example maintenance, the invention provides making it possible for these components to be detached from the machine as a self-contained structural unit and replaced by other units. This is achieved according to the invention by mounting a pressure roller (6) in a bearing block (18) which is connected releasably with the housing (28) of the drive, the bearing block (18) preferably being held in a guide (30) of the housing (28) so as to be displaceable by the drive for the pressure roller (6). This results in the advantage that the pressing stations can be detached from the tabletting machine as structural units for maintenance at a remote position, to be replaced in the meantime by structurally identical parts or the use of identical structural units. …<IMAGE>…

Abstract: Municipal sanitary sewage sludge is disposed of by an improved partial oxidation process without polluting the environment. Aqueous slurries of sewage sludge are upgraded by hydrothermal treatment, preferably while being sheared, concentrated, and then mixed with a supplemental fuel, preferably coal. A pumpable aqueous slurry of sewage sludge-coal and/or petroleum coke is thereby produced having a greater total solids and heat content (HHV) as well as containing an increased amount of sewage sludge for reacting with free-oxygen containing gas in a free-flow partial oxidation gas generator. Hot quench water or steam produced by cooling the hot raw effluent stream of synthesis gas, reducing gas or fuel gas from the gasifier may provide heat for the hydrothermal step.

Abstract: The method for optimum processing (cleaning) of textile fibres has the great advantage that cleaning steps are combined in a master process which contains in sections the part processes of bale opening (1), coarse cleaning (4), fine cleaning (6), carding (11) and mixing (62, 63, 67), and that machine settings corresponding to the origins, or a mixture of these, of the fibre stream running through are carried out, during the course of the process, as a function of predetermined values and process feedback. From the main fibre stream, part fibre streams are fed to a parallel mixing operation or homogenising operation, in order to achieve, in the mixing apparatus, not only the mixing and homogenisation, but also a time-buffer effect. Between the initial product and the final product extends a two-dimensional process field which is formed from a linear main process chain (that is to say, the machine installation) and the number of origins (A, B, C, D, E) to be processed, that is to say the number of different products to be processed simultaneously. Since not all the products can be processed at the same time, but only in succession, and this only with different respective sets of machine parameters, a parallelising machine element of the process chain, namely the "mixer", is additionally used as a buffer element. It is also a condition that it should be possible for the machine settings to be carried out automatically according to predetermined parameters. The two-dimensional process fields can thus be incorporated into a one-dimensional process chain. <IMAGE>
