Patent DE-3007087-A1 (DE)
Inventor: STRACK HANS DIPL CHEM DR
IPC: C01B39/16
Filed: 1980-02-26
Abstract: Crystalline zeolite powder of Type A is employed as a phosphate substitute in washing agents. For this use, it is advantageous if the crystalline zeolite powder of Type A has a specific average particle diameter of 4.3 to 8.5 mu  as well as a specifically narrow particle size distribution. By a specific sequence in the addition of the reactants in the precipitation of zeolites A this requirement of the product is fulfilled. Thereby water is present in a receiver and there are simultaneously added sodium aluminate liquor and waterglass solution and subsequently after a long stirring phase there are added further sodium aluminate liquor and further waterglass solution. The maximum grit content of the zeolite powder of Type A obtained is 0.2%.

Title: Lighting control circuit for indoor tennis courts - has individual light level monitors connected to common average value computing circuit and switch unit
IPC: H05B37/02
Filed: 1980-03-05
Abstract: The lighting system for a hall containing e.g. four indoor tennis courts permits individual lighting level control for the courts, and also compensates for daylight conditions. Each court has a light level monitor and is each connected by a switch to an average value former common to all four, giving an output signal to a controller. The switches are operated by a monitoring device which senses which courts are switched off or on, and which can operate each individual level controller. The monitoring device also includes a delay device for operating these controllers, and a further section connected to a second average value former, to operate it when all the individual controllers have been switched off. The second average value former is connected to a limiting value transmitter.

Title: Biological tissue specimens prepd. in paraffin - with pretreatment steps using pref. isopropyl alcohol all carried out in same receptacle and containment
Inventor: BERGER HERMANN JULIUS DR
IPC: G01N1/36
Filed: 1980-12-17
Abstract: A method of embedding one or more specimens of tissue in paraffin, comprises pretreatment by a fixing agent, removal of contained water by alcohol, soaking in liq. paraffin and finally embedding in a paraffin block. All these process steps are carried out with the specimen of tissue in the same receptacle possessing a sieve-type base and inside a single working containment vessel. For the fixing pretreatment of the specimen a first filling of isopropyl alcohol (pref. at 60% concn. e.g. with formalin additive) fills the containment vessel, then for removing the water in the next step a second filling of isopropyl alcohol (pref. 100% concn.) is introduced into the containment vessel; this is then displaced by a third filling of liq. paraffin, which in turn is replaced by a fourth filling of water at a temp. equal to or higher than the melting point of the paraffin such that the liq. paraffin remains in the receptacle. Finally, the water of the fourth filling is cooled. Used fot the prepn. by embedding in paraffin of tissues of humans, animal or vegetable origin.

Title: Shutoff and regulating element of a steam pressure reducing valve
Inventor: MATTHES EKKEHARD
IPC: F22G5/12
Filed: 1981-01-12
Abstract: The invention relates to a shutoff and regulating element (1) of a steam pressure reducing valve, consisting of a closing element (2) which can be secured on the valve spindle (13) and pressed against the valve seat (3) and of an adjoining hollow-cylindrical restriction element (5) which is provided with radial holes (4) and into the interior of which cooling water can be sprayed. In order as far as possible to avoid fatigue and wear phenomena on the restriction element (5) of a shutoff and regulating element of this kind, caused by extreme pressure and temperature differences, the invention proposes that the wall of the restriction element (5) consist of at least two hollow cylinders (6, 7) inserted coaxially with respect to one another and connected to one another at one end, it being possible to manufacture these hollow cylinders from different materials. In this way, it is possible, by appropriate selection of materials, to match the restriction element (5) to the different local conditions, by, for example, employing a material which is particularly resistant to thermal shocks and corrosion-resistant for the inner hollow cylinder (7) and a material which has a particularly high mechanical strength for the outer hollow cylinder (6). <IMAGE>

Filed: 1981-04-04
Abstract: A method and a device for carrying it out are disclosed which make it possible to control the orientation of particles as they pass through a detection zone in a particle analysis system for determining the shapes of the particles. A laminar flow alignment of the particles takes place in a flow which passes through an elongated straight passage and which is aligned coaxially with respect to an elongated detection zone.

Title: Arrangement for supplying pressure medium to a plurality of fluid motors connected in series
Inventor: OSTWALD FRITZ DIPL PHYS
IPC: B60T8/44
Filed: 1981-07-11
Abstract: The invention has, as departure point, an arrangement for supplying pressure medium to a plurality of fluid motors connected in series, in particular for motor vehicles, having a pressure-medium pump and having a steering servo-valve which is constantly located in the pump delivery flow and in the case of which at least one further fluid motor can be switched into the delivery flow of the pressure-medium pump. The known system has the disadvantage that the pump is coordinated with the sum of the maximum pressure pick-up of the fluid motors. In contrast, the arrangement according to the invention proposes to arrange the further fluid motor (12, 13, 14) between the pressure-medium pump (1) and the steering servo-valve (3) and to short-circuit it by a pressure line (20) which is through-connected in the normal manner. Use is also made of valve means (2) which can be switched by an electronic monitoring means and, when actuated, interrupt the pressure line (20). In this arrangement, brief overloading states of the pressure-medium pump (1) arise, but, owing to the short operating time of the further fluid motor (12, 13, 14), these are totally permissible. Owing to the use of a small pressure-medium pump (1), already present in the vehicle, for supplying the steering servo-valve (3), the arrangement is particularly cost-effective. <IMAGE>

Title: Camshaft for internal combustion engine
