Patent CA-1216165-A (CA)
Inventor: SCHOENHAUSEN HORST

Abstract: Abstract of the Disclosure A process  for the preparation and immediate use in situ of ready to use blends of structural material, such as plaster, mortar, stucco, tile adhesive or similar blends, which, in contrast to the usual methods does not use as a raw material a dry mixture of the three main components binder, filler and additives. Instead a dry mix of binder and filler is prepared at the building site, and an aqueous solution of the additives is added in a separate mixing operation, immediately followed by the application in situ of the finished blend. This method avoids the difficulties associated with the use of dry mixtures containing all three components. The invention includes an apparatus for mixing and immediate application of the blends as defined by the process claims. In an especially advantageous form of the invention, part of the aqueous solution of additives is added to the rest of the blend, after mixing and preferably at a point situated between the conveyor pump and the transport hose, in the form of a cylindri-cal thin concentric mantle surrounding a core of the wet blend. Much of the friction between the structural blend and the trans-port conduit can thus be avoided, as well as the wear associated with it. The application of the structural blend can be assisted by pressurised air injected into the stream upstream of the applicator nozzle. The stream of air may be loaded with airborne particles of silicone solution in order to impart water repel-lency to the structural layers made by the process.

Abstract: ABSTRACT OF THE DISCLOSURE          A system for draining condensate from a temperature regulated, steam operated heat exchanger. A buffer tank having a volume at least equal to that of the steam compartment is connected to the steam side of the heat exchanger, and a drain line extends from the bottom of the buffer tank to a condensate collection pipe located above the buffer tank.  The drain pipe from the heat exchanger included an air venting device and a control pipe having a non-return valve linking the top of the tank to the steam side of the heat exchanger.  During low load opera-tion of the heat exchanger, air from the top of the buffer tank can flow  back to the steam compartment of the heat exchanger to equalize the pressures and permit drainage of the condensate even during low load conditions.

Abstract: ABSTRACT OF THE DISCLOSURE         A selector detent means in a gear shifting device on,  or  in  conjunction with,  a  rotating shaft,  the  axial displacement  of  which,  from the neutral  position,  serves to  select  a  gate,  whereas  the  rotation  thereof  engages the  gears.   Arranged in  the  rotating shaft,  or upon at least one  locking ring,  are locking paths which act only in  the  selecting  direction  and  cooperate  with  at  least one  detent element guided in the control housing.   Under the action of a spring, being against the control housing, the detent element  is  urged  towards  the locking path so that,  under the action of the locks, a locking projection occurs which makes it easy for the driver to find the gates as he moves  the  gear shift  lever.   Under the additional action  of  a  holding-coupling  spring  assembly,  the  gear shift  lever  is  guided back  into a predetermined gate or the  detent  elements  are  preferably  designed  pivotably, e.g.  as  detent  levers,  and are mounted upon a first pin secured,  in  the  control  housing,  at right angles  to the rotating shaft.   A projection on the detent lever is in operative connection only with the locks of a detent ring and the pivoting movement of the detent lever is restricted by  a  second pin  arranged  in parallel  with  the  first in an opening or elongated hole, in such a manner that a gap occurs between the projection and the bottom of the locking path or of the rotating shaft.   As a result of the small amount  of  friction  during  the pivoting movement,  and of the  elimination  of  any  friction  outside  the  locks,  the gear shift is smooth and of simple design.

Abstract: Abstract Arrangement for connecting tooth replacement parts by adhesion, especially a prosthesis part with an anchor part or attachment part. It consists of a pair of connecting elements, or respectively of model parts for connecting elements, which are connected or can be connected with the parts to be connected, and of which at least one embraces the other. In order to be able to close the connection without the danger of thermal deformation, with correctly inserted individual components - possibly even in the patient's mouth - the surfaces to be connected of the connecting elements or of the model parts enclose an interspace which permits the adjustment of the parts to be connected, and can be filled with a hardening casting material, while the surfaces include surface portions which are undercut in relation to the releasing direction, and thus act in an interlocking manner on the casting material.         For the formation of the interspace, a special model part is provided, which can be inserted in identical shape between a model part for the inner connecting element and a model part for the outer connecting element.

Abstract: Abstract A transverse field interaction multi-beam amplifier device comprising a structure having, for example, a plurality of discrete cathodes cylindrically located in succession along a central axis of RF propagation.  In registration with the cathodes are a respective number of annular collectors located within an outer cylinder which also acts as the structure housing.  Intermediate the cathodes and collectors are two additional coaxial cylinders, one having a relatively smaller diameter than the other, with the smaller diameter cylinder including respective number of discrete grids, while the larger cylinder comprises a structure preferably having a rippled or undulating slow wave wall surface and a respective number of annular slots formed therein.  The cathodes emit radial beams of electrons which pass through and are bunched by the grids and then accelerated by the slots to the collectors while interacting with and being modulated by an input RF beam propagating along the central axis of the coaxial structure between a first pair of cylinder walls including the grids and cathodes and inducing an output beam in a second pair of cylinder walls including the slots in the slow wave wall surface and the grids.

Abstract: ABSTRACT An electrical wire has a conductor formed of a bundle of copper strands.  An adherent, electrically insulating, refractory coating extends around the circumference of the bundle but not around the individual strands. Extending around the individual strands is an intermediate layer formed from a metal which acts as a barrier to diffusion of oxygen or copper or both and having a thickness of at least 1.5 micrometres.  The intermediate metallic layer may be formed on the copper strands in a number of ways, for instance by electroplating, standard wire cladding techniques such as roll bonding, and by vacuum deposition techniques e.g. sputtering, evaporation, flame spraying, plasma assisted chemical vapour deposition (CVD) or other techniques.  The wire is particularly suitable for forming signal integrity cables and circuit integrity cables because, depending on the construction of the wire, when a portion of the cable is subjected to a fire, the refractory coating will pro-vide sufficient insulation between the conductors to enable the cable to operate for a significant length of time even when any polymeric insulation of the wire has been lost.
