Patent DE-3918267-A1 (DE)
Title: Pressurised liq. filter subsequently clears residual liq. - by spare elements, held inactive by valves during main operation
Inventor: GIESE MANFRED
IPC: B01D29/11
Filed: 1989-06-05
Abstract: Liq. is filtered under pressure while flowing radially inwards through tubular elements enclosed in individual casings. Filtrate discharges via valved outlets into a common header. During normal filtration, the valves controlling discharge in outlet and header cut off the discharge flow from one or more filter units, pref. near the edge of the assembly. In this period, liq. is delivered from a base outlet in a by-pass route, with a pump discharging liq. into the channel formed by an inclined collar plate below the pump discharge. A vertical weir in the channel ensures a free gap remains between collar and filter element. After cake build up terminates normal filtration, header valve is closed and outlet valves opened, enabling unused filters now to be used for residual liq. in the system. The valves may be manually or automatically controlled. ADVANTAGE - No separate filter is needed, as with known systems, for residual liq. after the main operation.
Patent DE-3918419-A1 (DE)
Title: Pulse modulation with constant pulse amplitude - scanning carrier signal with threshold values for generating modulated pulse train
Inventor: BRAUN CHRISTOPH
IPC: H03K7/00
Filed: 1989-06-06
Abstract: The pulse modulation uses a constant amplitude and scans the carrier signal by threshold values for generating a modulated pulse train. A sine-shaped carrier is scanned by a threshold value detector, e.g. an analog comparator. The comparator threshold value is engaged by the modulated low pass signal. The modulated signal consists of pulses of constant amplitudes, whose time position is determined by the threshold value scanning. Alternately a carrier signal is scanned by time-constant threshold value, such that a modulated low pass signal is superimposed onto the sine-shaped carrier. USE/ADVANTAGE - For digital transversal filters, with improved and reliable operation.

The bar has a support edge or surface on eahc side of its lengthwise axis. ADVANTAGE - The extent of twist between the front and back parts of the shoe's sole can be adjusted to the sportsman's individual needs.

Title: Guiding corpuscular probe in region of sample - following signal of interest along conductor path of integrated circuit whose layout is not fully known
Inventor: BRUST HANS-DETLEF
IPC: G01R31/305
Filed: 1989-08-24
Abstract: The sample (IC), esp. an integrated circuit, has a characteristic quality. The sample is scanned by the probe (PE) in the area of a first point. The scanning is achieved by relative movement of the components in two directions orthogonal to each other. The measuring signal (MS) from the probe is recorded. The measuring signal is used to determine at which points of the sample the characteristic quality is in evidence. The sample is deflected in the region of a second point displaying the characteristic quality. The steps are repeated accordingly. USE/ADVANTAGE - Tracing local path of signal to integrated circuit. Spiral movement of electronic probe through computer control reduces time taken.

Title: Waste incineration slag utilisation - as pelletised aggregate for concrete
Inventor: SEEMER HORST DIPL ING
IPC: C04B18/02
Filed: 1990-04-11
Abstract: In the utilisation of waste incineration residues involving use of the slag prod. as a building material, the novelty is that the slag is homogenised by crushing, pelletised with binder and then used as a concrete aggregate. The crushed slag may be mixed with flyash and may be freed from other valuable materials before treatment. In one method, the slag (and opt. flyash) is mixed with bitumen and pressed to moulded aggregate, in which case the slag is cooled to about 200 deg.C before crushing and the recovered heat is used in the bitumen mixing stage. ADVANTAGE - Toxicity problems (esp. due to sulphates, heavy metals, mercury and dioxins) are overcome by firstly binding in the pellets and secondly by encapsulation in concrete.

The taste of cigarettes is better than with cellulose acetate filters, or at the same intensity of taste, the cigarette smoke is more dil..
Patent DE-4032941-A1 (DE)
Title: Fasle-twist spinning -  has pneumatic rotor action followed by airjet spinning to produce a folded thread or cord
Inventor: STAHLECKER FRITZ
IPC: D01H1/115
Filed: 1990-10-17
Abstract: A pneumatic process to spin with false-twist, takes a double roving through the drafting zone. The rovings at the output of the draft are held at a distance which is less than twice the staple length. Two rovings are drawn in direction through the drafting aprons and out at the roller pair, across a perforated suction roller and then through the airjet spinning device. Then the folded yarn is taken through the roller pair to the creel. The rovings are held in the nip of the roller pair at the required distance apart, so that the action of the perforated roller draws the loose fibre ends away from the core fibres, to enable the airjet to wrap it around the core efficiently. The perforated roller is driven as a rotor at a higher speed that the two roller pairs. USE - To produce a folded yarn, so twisted into a yarn or thread, that the separate components are unidentifiable.

Title: Spinning frame service robot - has automatic programme and equipment to release and reset drafting zone pressure rollers
Inventor: GOEBBELS HEINZ-DIETER
IPC: D01H13/14
Filed: 1990-12-18
Abstract: Spinning frame has a series of drafting zones. The top cradle for the cots provides the pressure, which is occasionally released and re-applied by the equipment on a service robot which is carrying out other tasks simultaneously. The drafting zone (6) is repeated in units along a frame. A service robot (26) has electronic control (27), including a programme (28) for release of pressure rollers (16, 17, 18). These have synthetic roller covering which lose shape if not occasionally released. The cradle (9) is hinged (10) and pressed into position and locked by the lever (29) hinged (30) and weighted (31). A controlled pneumatic cylinder (40) releases the lock by upwards movement of the shaft (41). The electromagnetic end (43) is switched on when bringing the arm back into the locking position. Similarly, the cylinder (39) presses the shaft (42) forward, raising the locking arm (34) which holds the cradle back in the open position when pin (33) is in the hook (38). When the frame is stopped, the service robot travels along the units, locks into the correct position at each one and releases the cradle (9) one after another. Before the drive is set in motion, the robot travels along the frame and re-sets each cradle in the operating position. ADVANTAGE - The roller coverings are released from pressure against the drive rollers, to allow them to regain their correct shape. The task is performed automatically.

Title: Removing materials from separator esp. fat separator - by breaking up solid material using stationary, angled water jets, and then mixing and pumping off
Inventor: KESSEL BERNHARD
IPC: B01D17/02
Filed: 1991-06-13
Abstract: In removal of materials from a separator, sepd. material is broken up before pumping away. Floating materials are broken up by angled, stationary water jets and thoroughly mixed in a circulating stream. The separator has at least one sepg. chamber for the floating materials with two or more water jets which impinge diagonally onto the surface of the sepd. material. The jets are arranged at a mutual distance from each other and are connected to a high pressure pump. The separator has a sludge chamber (S) and an adjacent sepg. chamber (I) for floating materials. Waste water mixed with fat passes through a supply tube (2) into the sediment chamber (S) where solid material settles out. Floating material flows with the water over a sepg. wall (3) into the sepg. chamber (I) and gradually separates from the water. Clear water flows under a sepg. wall (4) and through an outlet (B) into the sewage system. USE/ADVANTAGE - Esp. for removing fats from waste water, is fast acting and enables solidified material to be satisfactorily pumped off.
