A flotation machine for de-inking waste paper stock comprises a horizontally extending flotation cell (5) defining a reservoir for a stock liquid which forms a free liquid surface in the cell. A froth receptacle (4) extends along the entire length of the cell and receives froth floating up to the liquid surface. At opposite ends of the cell are a stock inlet (1) and a stock outlet (2). Situated wi...

In a metallic mold, all or a part of the annular portion for molding at least the tread of the tire is formed by a plurality of small separate pieces (10, 11, 12) that can be combined to form said annular portion. Between these small pieces, during the molding of the tire, clearances are maintained so as to permit the passage of air but not the passage of rubber. The above clearances are connected...

In the production of threads textured by false twisting, the threads are wound to form a cross-wound bobbin which is made biconical only in its lowest layers, specifically to a layer thickness of up to 30% of the total winding layer, but which is otherwise wound with straight end faces.

In order to determine a malfunction which results in the loss of torque reduction control, the engine speed and the torque converter characteristics are monitored when a torque down signal is issued. The maximum engine torque which should be produced under such circumstances is used to derive a corresponding maximum engine speed value. If the actual engine speed exceeds the estimated value, approp...

The control valve with magnetic drive is provided with an inlet connection and an outlet connection with a controllable aperture which by means of a spindle interacts with an axially displaceable piston. The piston (26) is equipped with a servo control unit (50) for adjustment of its position.

Disclosed is a process for preparing a rigid, hydrocarbon-blown, polyurethane foam by reacting a polyisocyanate with a polyurethane precursor composition comprising a polyol and a compatibilizing agent containing a compatibilizing radical of the formula: -(CnH2n+1) wherein n is a number greater than or equal to 5, and wherein the compatibilizing agent contains at least one active hydrogen atom, pr...

A process for making flexible polyurethane foam, employing a silicone surfactant composition containing 5-20 wt % of a defined low molecular weight silicone surfactant and 95-80 wt % of a defined high molecular weight silicone surfactant. Use of the claimed mixture of surfactants provides product foams having improved breathability relative to foams produced using high molecular weight silicone su...

The device comprises a turn-over bladder 1 capable of moving axially towards the centre of the drum 3 in the manner of a caterpillar track. Its movement is controlled by the inflation of a thrust bladder 2.

A plastic retainer (26) has a pair of axially spaced cylindrical rings (28,30). Retainer arms (32) for retaining an upset portion (33) of a tube (22) within a housing bore extend from said rear ring (30), and a plurality of webs (46) connect the front and rear cylindrical rings (28,30) of the retainer (26). When a tube (22) is initially inserted into the housing bore, it contacts an inner peripher...

Mattresses conventionally are covered by bed sheets having a size to extend beyond the borders of a mattress on which it is to be placed so that its projecting edges may be tucked under the mattress. It is often difficult to apply a sheet smoothly and, in particular when a person is resting or sleeping on the mattress, the sheet may be pulled out from under the mattress and be displaced. The inven...

The prodn. of fire resistant isocyanate-based rigid foam, esp. rigid polyurethane and polyisocyanurate (PU) foam, comprises reacting opt. modified polyisocyanates with high-mol. wt. cpds. contg. at least two reactive H atoms and opt. low-mol. wt. chain extenders and/or crosslinkers, in the presence of blowing agents, catalysts, fire retardants (I) and opt. other additives etc. Component (I) consis...

Two plate-like supports of transparent material sandwich a laminate arrangement (3) consisting of two layers (4,5) of a laminatable material, enclosing a patterning layer (6). The patterning layer is pref. a printed textile fabric, leather or paper. The support plates are pref. of flat or curved glass plates. Also claimed is a method of mfg. the composite body by assembling the components in a san...

The support (3) accommodates rods (5) and the collapsed canopy (2). The canopy is interrupted between adjacent rods so that normal or radially to the stand the rods can swivel relative one another round a stand-parallel or vertical line. The rods lie parallel and can swing into or out of the housing or cavity slot (8). The canopy is interrupted at opposite points allowing multiple sets to move in...

A polyester film that can provide a leader tape wherein the surface unevennesses of the etched part are minute and uniform and which is excellent in appearance, does not cause magnetic tape troubles, and has a high commodity value; and a process for producing a polyester film that can provide a leader tape having an arbitrary thickness distribution pattern with a good reproducibility, that can pro...

Tire components are assembled on a tire building drum by laying a first liner on a surface of the drum, positioning first sidewall inserts below the cylindrical surface of the drum and around the drum at insert locations spaced from each end of the drum, laying a first carcass ply around the drum, positioning second inserts over the first ply at the insert locations, laying a second carcass over t...
