Abstract: Abstract The invention relates to a prefabricated concrete component system for forming ground-bearing stairways, platforms, terraces and analogous structures of one or more layers. It is the object of the invention to be able to construct, from a few basic components, a durable and safe ground-bearing structure of the desired shape. Such a component system comprises at least three different basic components (1, 2, and 3), which are used together or separately and which are slab components provided with upright supports.          The basic components of the component system according to the invention are so designed that one or two adjacent slab components in the same constructional layer form at least two support and fastening surfaces for the next higher slab component. Thus a sturdy and safe structure is obtained.          The shape of the components enables them to be cast in a single-part casting mold, from which the component will detach owing to beveled surfaces. The system also includes ramp components, edge components provided with edges, and corner components.            Figure 8

Abstract: Abstract of the Disclosure Improved techniques are provided for adjusting the axial position of a rotatable valve closure element carrying an elastomeric annular seal with respect to a metallic valve body.  An adjustable nut is threaded to the valve body and includes a recess for receiving a lower stem of the valve closure member.  One or more interference members are spaced radially between the nut and the lower stem, and permit axial movement of the lower stem and thus the annular seals with respect to the valve body, while enabling the valve closure member to freely rotate during normal use of the valve.  According to the method of the present invention, the lower stem is positioned within the recess of the nut, interference members are then fitted therebetween, the subassembly is then connected to the valve body and the shaft end interconnected with the valve closure member, and the closure member and seal are then centered with respect to the valve body by rotating the nut, which is then locked in position with respect to the valve body when the desired axial position has been achieved.

Abstract: ABSTRACT OF THE DISCLOSURE      A retractable turn-over type rearview door mirror in which angular adjustment of the mirror member can be effected by manually operating an actuation lever.  By using a certain linkage mechanism, a favorable correspondence is achieved between the direction of movement of the actuation lever and the direction of movement the mirror member.  The use of a clutch unit permits the adjusted state of the mirror member to be conserved, even when the rearview door mirror is retracted and restored, by minimizing the influences of the retracting movement upon the linkage mechanism. This can be accomplished by applying a suitable amount of friction to the linkage mechanism, but, by using a lock lever which fixes the angular orientation of the mirror member when the rearview door mirror is retracted, the angular orientation of the mirror member may be kept fixed without requiring such a friction and it allows the operation of the actuation lever to be performed with a small force.

Abstract: ABSTRACT OF THE DISCLOSURE           Communication apparatuses which utilize telephone lines and which have a function called repertory dialing are disclosed.    In  the  repertory dialing mode,  pairs  of  a destination  telephone  number  and  a  number  corresponding thereto, e.g. of two digits called a compressed dial number, are stored in a memory provided in the telephone set or the like.    The  telephone  calling  operation  is performed  by entering only the compressed dial number corresponding to a desired destination telephone number.   According to the invention, a communication apparatus activates or deactivates the compressed dial number mode by detecting the on-hook or off-hook state of the handset by means of a hook state detector.   When the handset is in the on-hook state, the compressed dial number mode is selected.  By operating the dial number keys to enter a compressed dial number in this state, a corresponding destination telephone number is read out of the memory and the calling operation is performed. Thus the telephone number entering operation is simplified to enable an accurate and quick input operation.

Abstract: Method of producing printing plates by means of a laser beam, said laser beam being scanned by means of a rotating polygonal mirror (32). According to the invention the rotational movement is transferred to the polygonal mirror (32) by means of a magnetic coupling, possible oscillations being dampened by a hysteresis-dampened, i.e. a faraday-dampened, magnetic coupling. The magnetic coupling is formed by intermeshing, radially projecting members, which can be slightly rotated relative to one another and which comprise strong magnets (62) . The resulting rotational accuracy is 6 ppm per rotation. In this manner it is possible to perform a laser scanning at a high speed while maintaining a high accuracy. The rotational shaft of the polygonal mirror (32) is disposed in an air bearing and comprises a cylinder (53) of a relatively heavy material, such as granite.

Date Nov. 16, 1989.In a centrifugal separator there is formed within the rotor a separating chamber (7) and a central chamber (26), which latter communicates with a peripheral part of the separating chamber through a channel (19a, 19b). The part (19a) of the channel situated closest to the central chamber (26) extends substantially parallel with the rotor axis, whereas the other channel part (19b) forms an angle with the rotor axis. For avoiding that solids entrained by liquid entering the channel (19a, 19b) from the separating chamber (7) are separated and depositing on the outer wall of the inner channel part (19a) a partition member (44) is arranged in this inner channel part (19a). The partition member (44) divides the channel part (19a) into two parallel flow ways (45, 46). Further, a pumping means (31) is arranged to pump liquid from the central chamber (26) to one (45) of said flow ways, so that this liquid flows through first said one (45) and then said other (46) flow way and then flows back to the central chamber (26). By the liquid circulation thus established in the inner channel part (19a) the solids are maintained suspended in the liquid until it again leaves the channel part (19a).

Abstract: 1490227 Flotation apparatus; dispersing gases in liquids PIELKENROOD-VINITEX BV 6 Dec 1974 [22 Dec 1973] 52771/74 Headings B1C B1D and B2H A method of separating suspended material from a suspension comprises reducing the pressure of a pressurized liquid containing gas or a volatile substance to form a dispersion of gas bubbles in the liquid, and introducing the liquid into a tank containing the suspension and forming part of a plate-type separator 7 so that the bubbles become attached to the suspended material and cause it to float. In the embodiment shown the suspension is introduced to a chamber 3 through a duct 11 and a nozzle 12, the latter consisting of a tube having a longitudinal slot. A pump 16 draws in air through a pipe 18 and liquid through a pipe 17 and produces a pressure in a pipe 14. This pressure is suddenly relieved beyond a valve 15 to produce a dispersion of air bubbles in the liquid which is injected into the chamber 3 through a nozzle 13. Floating material passes over a weir 5 into a discharge chamber 6 and sediment is collected in a hopper 10 after passing through an assembly 7 of superposed parallel corrugated plates. In another embodiment, Fig. 3 (not shown) there are separate pumps (16) and (21) for the liquid and air which may be stored under pressure in a mixing vessel (22) before passing through the valve 15. The suspension to be treated and the dispersion of gas bubbles in the liquid may be introduced into the chamber 3 through the same nozzle, and in another modification the suspension itself is pressurized and mixed with air to form the dispersion of gas bubbles. The suspension may be subjected to a coalescence treatment in a device located either inside or outside the chamber 3.
