The wind machine has a tower frame formed by four converging beams(12). At the is a gear head(26) connected to a wind driven multibladed fan(48). A vertical shaft(27), which is reciprocated vertically as the rotor rotates, is connected to the gear head. A counterbalance assembly(52) has tubular arms at opposite sides of the vertical shaft. The arms are slidablycarried by sleeves pivoting in ver...

PURPOSE:To both remarkably improve mechanical strength of a plate and eliminate powdery dust of a lead compound after drying, by immersing the light weight thinned plate after being filled to be applied in liquid in which lead powder is mixed in a suitable amount of glycerine aqueous solution. CONSTITUTION:A treated layer of mixed liquid, in which lead powder is mixed with glycerine or glycohol or...

In a method of manufacturing positive tube plates for accumulators a mixture containing essentially Pb and Pb compounds is filled into the tubes of the tubular pockets, which contain a lead core connected to the terminal strip, from the ends of the tubes remote from the terminal strip, until the tubes are full, whereupon the filling openings of the tubes are closed. In this method lead dust is gra...

A thread delivery device is disclosed, particularly for supplying elastomer threads in circular knitting machines or circular hosiery machines. An endless belt (1) is guided in a horizontal plane along the periphery of the machine by means of guide rollers (2) mounted for free running, and is driven at a predetermined speed. It is in friction engagement with the peripheral surface of delivery spoo...

Prior to the actual splicing process, a preparation process is carried out in a preparation apparatus. The apparatus comprises a preparation tube having one or more circumferentially arranged air jet nozzles. The axis of each nozzle is inclined to the axis of the preparation tube and has a mouthpiece at the inlet end. The yarn end to be prepared is introduced into the preparation tube, where it is...

The invention relates to a collecting container for roving tubes on spinning and twisting machines, having a pivotably mounted bottom flap. The object on which it is based is to reduce the outlay and the space requirement and to lower the proportion of manual activity. This object is achieved in that the collecting container (1) for roving tubes is movable along the machine, a spring (3) is connec...

The invention relates to polyetherurethane particles having absorptive activity whereby these particles may be applied for the extractions or the separations of metal ions from liquids, e.g. from waste liquors leaving galvanizing, printing and metal working industries. The particles are of a spherical shape, have a bulk density of at least 0.5 g/cm3 and are resistant against acidic liquids. The in...

An automatic running work vehicle which is adapted to repeat a running travel reciprocatingly and which has means for teaching the running course of one travel by sampling the running direction detected by an orientation sensor every predetermined running distance detected by a distance sensor during the travel and for steering the work vehicle based on the information of running course taught by ...

The shell is removed from a crustacean by creating a pressure difference across the shell. Initially the crustacean is heated until body liquid adjacent the shell is just below boiling point. The pressure on the crustacean is then suddenly lowered to induce the liquid to boil and thereby create the pressure difference across the shell. After pressure treatment, the crustaceans are projected into a...

A heat wave shielding lamination consisting of at least two In2O3 shield layers containing different amounts of Sn is provided on the surface of a glass substrate to provide shielding against heat waves without causing heat wave pollution in the surrounding environment. The amount of tin contained in the respective layers increases with increasing proximity to the substrate. The heat wave shieldin...

An automatic running work vehicle in which both front wheels 2 and rear wheels 3 can be steered and which is provided with a follower sensor A for detecting the boundary between an unworked area and a worked area and an orientation sensor 5 for detecting the running direction so as to run automatically along the boundary. Based on the result of detection of the boundary by the follower sensor and ...

An automatic running work vehicle adapted to repeatedly work on the ground while automatically changing its running direction and provided with means for controlling the vehicle body so that the vehicle body will be automatically positioned, upon a change of direction after finishing one course, for the next course with its orientation and position in match with the boundary of the course.

A composite ski binding which allows downhill skis to be converted to touring or langlaufing use by use of a clip-in base (13, 14) provided with an upper footplate (16) rotatable about said base (13, 14) in a substantially transverse axis (19) in relation to said base (13, 14). The axis of rotation (19) is substantially intermediate the ends (17, 18) of the footplate. Preferably the base (13, 14) ...

An absorbent material is produced by exposing an aqueous solution of polyvinyl alcohol and a low molecular weight, water soluble copolymer containing polymerized oxyethylene and oxypropylene units, to sufficient electromagetic or corpuscular ionizing radiation to form a gel.
