Abstract: An oil separator device (1) of stainless steel for separating oil or fat from a liquid mixture consists of a tank (2) in which, by means of a submerged wall (3), a preprecipitation chamber (4) is separated off, in which floating oil or fat as well as sinking solid particles are separated due to their density from the liquid mixture running in and, by means of a baffle (12) provided underneath the submerged wall (3), are prevented from being transported into the compartment (5), separated from the preprecipitation chamber (4), of the tank (2). The compartment (5) separated off is designed as a microfiltration stage, in which a submerged circulation pump (16) is provided which draws liquid from the separated compartment (5) and forces it through a crossflow filtration unit (19) protruding into the tank (2) and having ceramic tube membranes, from where purified permeate is discharged and retentate which has been enriched with oil or fat and has not passed through the pores of the ceramic tube membranes is returned into the separate compartment (5). The oil separator device (1) with integrated microfiltration is particularly heat-resistant, compact and easy to maintain and, because of its small space requirement, is suitable as a mobile unit, which can also be used in a decentralised manner, for extending the service life of degreasing baths etc. <IMAGE>

Inventor: MUELLER WERNER
IPC: D06C5/00
Filed: 1993-07-03
Abstract: What is indicated is a method for the thermal treatment of tubular, elastically stretchable material, especially for the drying and/or smoothing of stockings, tights and the like, in which the material (24) is stretched on at least two adjacent legs (14) of an elongate form (12) and is then subjected to heat for drying and/or smoothing. During the thermal treatment, the legs (14) are driven in rotation about their longitudinal axis, the direction of the rotational movement preferably being reversed alternately. Stripes, especially during the shaping of stockings, tights and the like, are thereby prevented from occurring. A suitable apparatus has at least one elongate form with at least two adjacent legs, on which the material (24) can be stretched, and is provided with a heating device (36) for heating the material. The legs (14) of the elongate form (12) are mounted rotatably about their longitudinal axis and are connected to a drive device (34), for example via a chain drive (26). <IMAGE>

Abstract: With reference to Figure 3, an electrically-powered heating panel 1 of flexible construction, in the form of an under-carpet heater comprises, a dual wire heating cable 2, with inner 3 and outer 4 heating wires thereof connected in series together, with fuse means 5, the inner and outer heating wires 3, 4 being of substantially equal electrical resistance. 
     The inner and outer heating wires 3, 4, which are of coiled form, are electrically insulated from each other by inner insulation 6 of thermoplastics material. (Polyethylene.) 
     Under normal conditions, the current flow from line  L  to neutral  N  is by way of fuse 5, inner heating wire 3, and then outer heating wire 4. 
     As the inner insulation sheath 6 is of polyethylene, this sheath will soften/melt and allow substantial electrical contact, (creating a short circuit), to occur between the inner and outer wires 3, 4 in the event of excessive overheating at any point along the length of the heating cable 2. 
     If a short circuit takes place at point "A" current will flow from the line  L , through fuse 5 and inner wire 3 and onto the neutral  N . 
     Thus only the inner heating wire 3 remains in use, the outer wire 4 being by-passed. This halves the nominal resistance of the heating cable 2, and doubles the current flow. 
     The increase in current flow may not be sufficient to blow the fuse 5 at once. However, the increased current will cause the inner insulation sheath 6 to further overheat, (and soften/melt), so as to cause further short circuits between the heating wires 3 and 4, and increase current flow sufficiently to ensure that the fuse 5 does indeed blow. The current supply is therefore terminated. 
     Wherever an initial short circuit occurs, the nominal resistance is halved.

Abstract: A metal laminate gasket of the invention is used for an internal combustion engine formed of a cylinder head and a cylinder block. The gasket is basically formed of two metal plates (10,11) laminated together. The gasket has a rectangular shape, and includes a plurality of cylinder bores (Hc) arranged in a longitudinal direction of the gasket, and a plurality of bolt holes (Hb) arranged to surround the cylinder bores. The gasket has two lateral side portions, each being defined between a lateral edge and a line linking centers of bolt holes (Hb) located adjacent to the lateral edge. Edge support shims (12) are installed between the plates at the lateral side portions to substantially completely support tightening pressure of the bolts applied to the lateral side portions. Thus, deformation of the cylinder head is prevented, and substantially equal tightening pressure can be formed around the entire cylinder bores.
