Abstract: The contact device comprises a metal plate (1) with a slit ex­tending to an edge (7) of the plate which separates two strip-shaped, resilient tongues (13) from each other and serves to take up a wire with an electrically conductive core (31) surrounded by an insulating jacket (33). Starting from the said edge (7) the slit successively com­prises a lead-in section (17), a scraper section (21) for cutting through the insulating jacket (33), a contact section (23) for making electrical contact with the core (31), and a circular first opening (5). By pressing a pin (25) with a diameter which gradually increases over its length into the first opening (5) the tongues (13) are bent away sideways from each other, so that the contact section (23) is approximately V-shaped. The scraper section (21) is formed by the transition between the widest part of the contact section (23) and a second circular opening (9) which is intersected by the split.

Abstract: In this method for manufacturing an aluminum alloy, a porous preform is manufactured from a mixture of a finely divided oxide (26) of a metallic element which has a weaker tendency to form oxide than does aluminum, and an additional substance (28) substantially more finely divided than that metallic oxide. Then an aluminum alloy containing a substantial quantity of silicon is permeated in the molten state through the porous preform. This causes the metallic oxide to be reduced by a thermite reaction, to leave the metal which it included as alloyed with the aluminum alloy. At this time, the silicon in the aluminum alloy does not tend to crystallize out upon the particles of the metallic oxide, which would interfere with such a reduction reaction by forming crystalline silicon shells around such metallic oxide particles and would lead to a poor final product, because instead the silicon tends to crystallize out upon the particles of the additional substance. This alloying method is effective even if the average particle diameter of the finely divided metallic oxide, on the assumption that it is in the form of globular particles, is less than about 10 microns. The melting point of the additional substance should desirably be substantially higher than the melting point of the aluminum alloy. The silicon content of the aluminum alloy may freely be greater than about 1.65% by weight. Desirably, the preform may further contain reinforcing fibrous material (30). And, particularly, the additional substance may be A1 2 0 3 .

Abstract: This specification is directed to a method of forming a glass sheet with an oil-base ceramic paint thereon, the method having the following steps. An oil-base ceramic paint is applied to the glass sheet. The oil-base ceramic paint includes normal ceramic paint components along with, as a new component thereof, finely divided zinc metal powder. The glass sheet is heated to a temperature which softens the glass sheet sufficiently so that the glass sheet can be formed. The glass sheet and the ceramic paint thereon are engaged with a fiberglass covered forming die to form the heated glass sheet to a desired shape. The forming die is removed from engagement with the glass sheet. The finely divided zinc metal powder addition to the ceramic paint is credited with being effective to prevent sticking of any of the ceramic paint to the forming die. The glass sheet is cooled to obtain a formed glass sheet with a ceramic paint thereon.

Abstract: A monocrystal rod (10) utilized for producing the semiconductor device or solar cell includes a neck section (3), a main rod section (4) and a shoulder section. The neck section (3) is smaller in diameter than a seed crystal (1). The main rod section (4) is formed integrally with the neck section (3) and is larger in diameter than the neck section (3). The shoulder section is tapered for linking the neck section (3) to the main rod section (4). The main rod section (4) has a stopper section (11) at the top portion of the main rod section (4), and the stopper section (11) is larger than the main rod section (4). 
     Also, an apparatus (20) for preparing the monocrystal rod (10) has a safety member (29) for supporting upwards the stopper section (11) of the falling monocrystal rod. 
     Further, a method of preparing the monocrystal rod includes the following steps. The seed crystal (1) is pulled out from a melt (22) in a crucible (21) while rotating it. The speed of pulling the seed crystal (1) is at first increased to grow the neck section (3) whose diameter is smaller than the seed crystal (11), and then is gradually decreased to grow the shoulder section. Subsequently, the pulling speed is increased again so as to prevent further increase in diameter to grow the stopper section (11) at the lower end of the shoulder section or at the top portion of the main rod section (4), and then is decreased again to grow the main rod section (4) whose diameter is equal to a required diameter.

The same pressures which tend to unbalance the valve member are impressed upon opposite sides of the bellows (18), one through an enabling bleed port (19), and resulting forces developed by the bellows (18) over a defined area are exerted upon the armature (8, 20) mechanically in a counterbalancing sense.

Abstract: The subject matter of the invention is a method for increasing the efficiency in the steam process, in which the steam (HT) generated in the steam generating process (1) with a hot material flow (14) is supplied into the steam turbine. The cooled steam flow (HL) coming from the steam turbine is condensed. The supply water (VS) of the steam generating system (1) is preheated.

The excess supply water (V1) is cooled in devices (11, 12, 13; 21) generating low-pressure steam (LP steam). The low-pressure steams (H2, H3, H4; HS) produced in this way are supplied into the steam turbine (3), as an intermediate supply, and are fed back, cooled, into the supply water preheater (9). The cooled excess supply water is fed back into the supply water (VS) running in the supply water preheater. <IMAGE>

Abstract: A single stage axial blower design provides a series of blowers producing a wide range of delivery flow rates even though they have the same outer dimension, drive speed and guide wheel. This is achieved by a structural combination which includes a stationary guide vane wheel (5) of fixed design and impellers (8) which have varying hub diameters (9, 9a, 9b) but the same outer diameter. Thus, a series of blowers having the same external dimensions and the same stationary guide vane structure can be used with a series of air-cooled internal combustion engines which differ from one another in number of cylinders and related cooling requirements.
