Title: "Diaphragm pump"
Inventor: STAHLKOPF FRIEDRICH
IPC: F04B43/107
Filed: 1981-05-27
Abstract: The invention relates to a diaphragm pump, in which the primary working medium (fluid) actuates a tubular hose diaphragm internally and in which the secondary medium is located in a pump chamber which surrounds the diaphragm and which is bounded, on the one hand, by a preferably spherical diaphragm housing and, on the other hand, by the outer surface of the tubular diaphragm which is clamped in the housing with its ends at both sides. The invention ensures that, for the generic diaphragm pumps in a multiple arrangement, the valves and fittings necessary for controlling the balance of primary working medium can be reduced to a minimum, i.e. in concrete terms to a single arrangement in each case for the entire multiple arrangement. This is achieved by at least two connection fittings, of which each in each case connects one spherical housing to a power component, are connected by means of a valve casing in which, for each spherical housing, a set of valves, consisting of an intake valve and a pressure-relief valve, is arranged. <IMAGE>

Title: Centrifugal separator
Inventor: WILSON JOSEPH G
IPC: B04C3/00
Filed: 1981-06-02
Abstract: A centrifugal separator has an external tube and an internal tube, which tubes are arranged concentrically with respect to one another and form an annular gas inlet channel between them. Slots in the internal tube produce a connection between the channel and the space within the internal tube. In a chamber on the floor of the channel, particle-shaped material is collected and this chamber permits excess gases to flow. With the aid of outlet devices, particle-shaped material is removed from the chamber. The separator has at least one swirl device in order to cause the gas in the channel to eddy. Separation of the particle-shaped material takes place when the gas enters the channel, when it changes its direction of flow and when it enters the slot. Cleaned gas emerges at the lower end of the internal tube.

Title: Process for the preparation of polyurethanes and polyurethane isocyanurates
Inventor: STRESINKA JOZEF DIPL ING
IPC: C08G18/42
Filed: 1981-08-06
Abstract: The invention relates to a process for the preparation of polyurethanes and polyurethane isocyanurates and in particular corresponding rigid foams based on polyester-polyols from petrochemical raw materials which are readily accessible in industry. The polyester-polyols employed according to the invention are prepared by reacting residues from the preparation of terephthalic acid and/or dimethyl terephthalate with polyhydric alcohols at from 120 to 280 DEG C, usually in the presence of esterification catalysts. The advantage of the process according to the invention lies in the industrial and economic utilisation of residues from the preparation of dimethyl terephthalate or terephthalic acid, which means that these industrial processes are virtually waste-free. Reaction of such polyester-polyols with diisocyanates or polyisocyanates in the presence of conventional auxiliaries gives access to rigid polyurethane foams having a uniform structure and excellent physicochemical properties, in particular uniform stability at low temperatures. The rigid polyurethane foams obtainable according to the invention can preferably be used in the refrigeration and construction industries.

Abstract: A vertical pipe (10) has a line connection (12) at the bottom for a rinsing liquid line (14) and a section adapted for pushing on a bag (34) further at the top having at least one outlet orifice (26) for the rinsing liquid. A lateral outlet orifice (24) which extends annularly at least approximately over the entire circumference of the pipe is formed at the upper end (16) of the pipe (10), and an air inlet (32) is located below the section of the pipe (10) adapted for pushing on the bag (34). As a result, the rinsing liquid emerging at the upper end (16) of the pipe (10) is given the shape of an umbrella which supports the bag (34) from the inside and thereby counteracts a collapse, essentially uniform rinsing of the entire inner surface of the bag (34) being achieved at the same time. In addition to the rinsing liquid, the interior of the bag (34) is supplied with air which inflates the bag (34) and thus also prevents the latter from collapsing, even in its lower region where the protective umbrella formed by the rinsing liquid is less effective. <IMAGE>
