Title: Lattice-work liners for wet-treatment vats for textiles - assembled from staves made of fluorocarbon! polymer
IPC: D06B3/26
Filed: 1978-11-22
Abstract: A liner or insert for vats and containers used for the wet-treatment of textiles comprises a lattice or grille of massive fluorocarbon polymer staves which are oriented in the direction of travel of the textile material. The staves are rectangular in cross-section, between 4 mm and 20 mm thick, preferably 8 mm -12 mm, and are fixed parallel to each other with a gap between neighbouring staves of 1/4 -1/3 the stave width. They are attached by means of screws or rivets to a series of short cross-bearers, whose lengths are less than the width of the grille and are arraned in staggered fashion across it. The frictional resistance of the fluorocarbon polymer to the movement of the textile material is lower than that of the previously-used stainless steel. It has excellent resistance to chemical attack, particularly by dye-liquors, and collects relatively little lint fro the material being processed.

Title: Profiled rods or pipes separating auger conveyor - has conveyor inlet ends forming fingers working with stop on auger between
Inventor: BRECHLER HANS-GEORG
IPC: B65G33/06
Filed: 1978-12-05
Abstract: The auger conveyor separates profiled rods or pipes and has a number of coaxial screwed spindles, each with an auger on a cylindrical shaft. The shafts rotate in the same direction and at the same speed. At the inlet are one or more stops for the rods etc as they roll down, while one or more fingers on one of the spindles work with the stop. The fingers are formed by the inlet ends (26) of the augers (25) on spindles (17, 19) separated from each other by a further spindle (18). The inlet end (57) of the latter act as a stop. The finger or stop spindles are adjustable on their respective shafts (30, 31,24) so that adjacent augers can be adjusted for angle in relation to corresponding rod diameters.

Title: Reflective casing for tubular fluorescent lamp - is divided by projecting centre into two regions reflecting light from rear of tube
Inventor: KORTE HEINRICH
IPC: F21V7/00
Filed: 1979-02-02
Abstract: The casing (1) for a tubular fluorescent lamp is designed to reflect light from behind the tube which is normally wasted. This permits good illumination for regions some distance away underneath. The lower surface (2) underneath the casing, and above the lamp (3) is treated to give good reflection, and shaped to form a beam each side of the lamp. The surface may be flat with a central triangular region with its two sides (5) sloping towards the centre line meeting at it.

Title: Pile-driver striker acceleration mechanism - has stop forcing piston in end buffer back against gas cushion
Inventor: KUEHN HANS
IPC: E02D7/06
Filed: 1979-04-03
Abstract: The percussion unit is designed to be used in a piledriver operating at high speed. It is mechanically or pneumatically driven to its far end position in a guideway. At this end there is a buffer (6) with a closed hollow space holding a gas cushion (10). The buffer has a piston (7), with limited axial sliding motion, protruding parallel to the track of the striker (4). A guideway (1) is fitted with a stop face pressing the piston back against the cusion, short of a predetermined striker interval from the far end point. This provides for increase in percussion energy and/or more rapid striking sequence.

Inventor: HEUFT BERNHARD
IPC: B07C5/36
Filed: 1979-04-27
Abstract: An apparatus for laterally deflecting selected articles from a first conveyor to one or more other conveyors comprises either extensible and retractable deflective segments, or gas nozzles whose intensity is adjustable. The deflective segments have tapered front faces which jointly form a smooth deflecting face whose taper increases in the direction of conveyance. The number of segments used depends on the speed component required, and the segments are extended by only a portion of the lateral distance the articles are to cover, the remainder of the distance being covered by the imparted inertia. Alternative embodiments include a deflecting wedge or flap.

Patent DE-2927275-A1 (DE)
Title: Thermal sepn. of oil-water emulsions - by hydrogen peroxide addn. to improve sepn. of oil rich phase which is re-used or burnt to avoid pollution
Inventor: KIECHLE ARNO
IPC: B01D17/09
Filed: 1979-07-06
Abstract: Sepn. of the oil from the water is facilitated by adding 150-3000 ppm., esp. 500-700 ppm., H2O2 to the emulsion. The emulsion is pref. heated to 75-85 deg.C prior to adding the H2O2; and sepn. is carried out at this temp. In the machining of metals etc., where turnings or swarf are obtd., an oil-water emulsion is used as both a coolant and lubricant; but the spent emulsion cannot be discharged into the drains for hygienic reasons. It is usual to heat the spent emulsion to separate the oil, but the process is veryslow and inefficient. The invention uses H2O2 to provide rapid and efficient sepn.

Title: Long exposure specialised camera - has low pressure sodium lamp with selective lens filter
Inventor: BAUM ECKART DIPL ING
IPC: G03B27/72
Filed: 1979-07-24

Patent DE-2931265-A1 (DE)
Inventor: HAPPEL FRITZ
IPC: A01J5/12
Filed: 1979-08-01
Abstract: The pulsator actuated by means of a low pressure source has pneumatic damping chambers (8, 9), a diaphragm (4, 5), which in each case bounds a damping chamber (8, 9), freely resting against a supporting element (13, 14), the shape of the latter being approximately complementary to the opposite wall of the damping chamber (8, 9). As a result of this, the volumes of the damping chambers (8, 9), which are connected to one another by means of a channel (10) with a throttle point (11), can fluctuate between a maximum value and a minimum value which is virtually zero, which prevents the impairment of operation by a pneumatic spring effect on a control spindle (12) which reciprocates in an axial direction and supports the supporting elements (13, 14) at its ends. <IMAGE>

Abstract: For simultaneous elimination and fixation of phosphates from phosphate burdened aqueous liquids like sewage water a deposit space is formed by a soil matrix containing iron and/or aluminum. The soil matrix is defined by layers of poor hydraulic conductivity along its sides and at the bottom thereof and Limnophytae species like Phragmites, Typha, Carex, Glyceria, Eleocharis, Juncus, Iris pseudacorus, Iris versicolor, Schoenoplectus, Phalaris, Arundo are planted in the soil matrix to form a reactive space penetrated by the root systems of said plants. The phosphate containing liquid is introduced along one side of the deposit space and leaves the same with a phosphate content in the 0.1 mg/l range at flow rates in the range of 10-3 to 10-2 m per sec. Valuable phosphate deposits useful as arable land not requiring any phosphate fertilizer or useful as recoverable phosphate are obtained in amounts depending on the capacity and time period of phosphate fixation.

Title: Woven heating or resistance element - having insulating warp with weft of large-gauge conductors in individual lengths
Inventor: RAHMLOW GUENTER
IPC: H05B3/34
Filed: 1979-11-29
Abstract: An electrical resistance or heating element in the form of a grid is woven from warp ends of insulating material, and weft picks of conducting material which are inserted into the shed as pre-cut individual lengths, having a length which exceed the width of the warp. The projecting ends of the conductors are subsequently joined together by soldering, welding, crimping, or by the use of screwed connectors, etc, in any desired pattern, to connect the conductors either in series or in parallel. The use of individual pick-lengths of conductor removes limitations on the gauge and the stiffness of the wire, and the number of wires per unit length of the warp, which are imposed if a continuous weft is used, which has to be bent through 180 deg.at the edges of the grid.
