Patent DE-3004961-A1 (DE)
Title: Construction of basket with internal fabric - for screening particles from cooling or drinking water
Inventor: LENZ RAINER ING GRAD
IPC: B07B1/10
Filed: 1980-02-11
Abstract: A basket with an internal screening fabric is affixed to belts motor-driven in a closed circuit or to circular holding drums and is intended for removing particles from outwardly moving liq. It consists of a hollow open structure assembled from angled and flat profiles welded into basket shape. A pre-formed fabric of corresp. shape is gripped inside the basket by clamping strips, washers and holding screws. The baskets are strong enough to resist the pressure differences arising during screening. Used for removing contaminating particles from drinking water or from the cooling water in thermal or nuclear power stations. The internal location of the fabric makes clamping bands unnecessary, and since standard profiles are widely used and less welding is involved, total production cost is reduced by about 40%.

Title: Explosion protected coal pulverising plant - uses protective gas atmosphere for all containers and dust separator for recycled hot drying gas
Inventor: DIEL WALTER
IPC: F23K1/00
Filed: 1980-04-10
Abstract: The coal pulveriser uses a protective atmosphere to exclude oxygen to reduce the risk of explosion and combustion . It has a silo for the material to be pulverised and container for transport which are protected by nitrogen. The input silo includes a level control system to ensure a minimum content of material to reduce the possibility of entry of atmosphere or oxygen into the interior. When the coal enters a predryer before grinding, it does not come into contact with an oxygen containing gas mixture. The warm drying gas is discharged from multiple entry positions so that its temp. remains at higher level to ensure an efficient moisture removal. All separated dust is removed by a flotation system. The gas in the water separator is dried, then reheated to pass through distributor valves for return to the drying and pulverising circuit. Between the water separator and the gas heater is an intermediate tank to equalise pressure surges.

Title: Safety circuit for bi-directional semiconductor switches - uses ignition pulse generator for different start and normal operation control, and comparator for pulse generator control
IPC: H03K17/082
Filed: 1980-09-15
Abstract: The circuit is intended for triac, or thyristors in anti-parallel, used in alternating circuitry as switches, when ignited by control signals of an ignition pulse generator. Alternately, they are used as power adjusters when operating according to the phase control principle. At the start of the forward switch condition the ignition pulse generator (2) energises the bidirectional switch (1) only by a preprogrammed, lower current flux angle. During the first half-wave, effective in the forward direction, a reference voltage (UR) is provided as a measuring value for the instantaneously flowing current in the load circuit. The reference voltage is supplied to a comparator (3) for comparison with a preset threshold voltage. On exceeding the latter, the ignition pulse generator receives a control signal preventing further ignition train at the bidirectional switch.

Title: Settling tank outflow channel scrubber - with reciprocating mechanism for brush assembly dragged by raker arm
Inventor: BORMET HORST
IPC: B08B9/08
Filed: 1980-11-26
Abstract: A scrubbing appliance for the effluent channels in sewage treatment plants, esp. for biological final settling tanks, consists of an assembly of brushes which are urged by springs against the side walls of the channel and its bottom. This assembly is dragged along by the raker arm of the settling tank. A reciprocating brush motion is superimposed to the drag motion by a gear motor which drives a crank mechanism for the one or two connecting rods, linking the raker arm to the brush assembly. The superimposed reciprocating motion results in a much better scrubbing efficiency for little extra engineering effort.

Patent DE-3120219-A1 (DE)
Title: Cutting-tool head, in particular countersinking- and/or reaming-tool head
Inventor: HOENE WOLFGANG
IPC: B23B51/04
Filed: 1981-05-21
Abstract: A cutting-tool head, in particular countersinking- and/or reaming-tool head, is proposed, with three indexable inserts, arranged at roughly uniform peripheral angular distances from one another, in mounting seats. The indexable inserts are fixed therein in such a way as to be locked against displacement. A central adjusting device sits on the head end. The adjusting device acts jointly and radially in a uniform manner on the three indexable inserts, and in fact in the area of the material elasticity of the head end and in the process in a reversible manner. At the head end, the adjusting device has a central and coaxial tapered bore with an adjoining tapped hole and, furthermore, a threaded shank which can be screwed into the tapped hole and has a tapered core at the end. The taper angle is equal and advantageously lies in the self-locking range. The tapered bore has such wall surfaces in contact with the pressed-in tapered core only in the radial area of the indexable inserts. Located in the peripheral direction between the wall surfaces are radial recesses which are axially parallel channels and encourage specific material deformation in the elasticity range. At least the head end is given spring temper. At least the tapered core is hardened and ground. By screwing in the tapered core, the tool head can be set in such a way that it enables bores with only slight tolerance and high quality to be produced, in particular with fits roughly in the range from IT7 to IT9.

Title: Enclosed electrical installation
Inventor: BRAND KLAUS-PETER DIPL PHYS DR
IPC: H02B13/055
Filed: 1981-10-24
Abstract: In an enclosed electrical installation, electrical components at high voltage, such as busbars, isolating switches and measuring transducers, are accommodated in compartments filled with insulating gas. The insulating gas contains sulphur hexafluoride and is at an operating pressure of approximately 1 bar. The object is to develop this installation further so that its dielectric strength above a minimum operating temperature of -10 DEG C is increased in an inexpensive and physiologically safe way and the soot formation due to the insulating gases used being decomposed by switching sparks is at the same time limited to an extent which is sufficient for practical applications. This is achieved as a result of the insulating gas containing 75-85 per cent by volume of bromochlorodifluoromethane (CBrClF2), 60-70 per cent by volume of dichlorotetrafluoroethane (C2Cl2F4), 60-70 per cent by volume of perfluorobutane (C4F10), 25-35 per cent by volume of tetrafluoro-2-butene (C4F8) or 25-35 per cent by volume of hexafluorocyclobutene (c-C4F6).

Title: Device for aerating and/or deaerating a room
Inventor: SAELZER HEINRICH
IPC: E04F17/04
Filed: 1981-11-17
Abstract: Arranged upstream of a ventilating device is an air duct (1) which is closed at both end faces and has an inlet opening (3) on one longitudinal side of the duct wall and an outlet opening (5) on another longitudinal side of the duct wall. The openings (3 and 5) are offset with respect to one another over the longitudinal extent of the air duct (1) and turned through 90 DEG  relative to one another. In addition, the duct wall is covered or lined with a material resistant to bombardment, so that, over the air duct (1) independently of the angle of bombardment, projectiles can neither pass through the duct nor penetrate from the outside into the interior of the room to be aerated over the course of the duct itself. By virtue of a special design of the duct cross-section, panels resistant to bombardment can be inserted and fixed via an end face of the duct which is initially still open, so that it is possible to use, for lining the air duct (1), individual panels (11, 16, 17, 24) resistant to bombardment which, by virtue of their arrangement, produce a lining without gaps except for the inlet and outlet opening (3 and 5 respectively). The end faces of the air duct (1) are sealed by means of cubic or parallelepipedal plugs likewise made of material resistant to bombardment. <IMAGE>
