Patent DE-2615744-A1 (DE)
Title: Static frequency changer output voltage and frequency control - uses EMF rather than motor terminal voltage to maintain three phase motor airgap flux constant independent of load and motor speed
Inventor: BLOECHER CHRISTIAN ING GRAD
IPC: H02P23/06
Filed: 1976-04-10
Abstract: The method is for regulating the output voltage and frequency of an intermediate circuit. A static frequency changer is for feeding a three-phase motor driven at variable frequency and speed. This maintains the air-gap flux of the three-phase motor constant, independent of the load and motor speed, and with the least possible expense on electronics and with high accuracy. The EMF (UR) is used rather than the terminal voltage (U2) of the motor. The true value of the EMF (Uh) can be automatically derived from the motor terminal voltage (U2) by means of an arithmetic unit, and to convert the terminal voltage to the EMF an approximation formula can be used to simplify the electronic balancing network required. More specif. the approximation formula is used in a form that allows minimum expense on electronic hardware to be realised.

Title: Thread breakage detector, esp. for wide looms - uses laser beam and sample and hold circuit respond rapidly
Inventor: HAUSER GUENTHER DR ING
IPC: D03D51/28
Filed: 1976-06-25
Abstract: The breakage of a thread in a loom is detected and recorded by means of a laser emitting a constant beam of light. In the optical receiving instrument the beam of light 1 mm. in dia. is focussed to a point and between emitter and receiver the beam is divided into a number of, and at least two, part beams. One of these is projected throught the shed and the other is directed beneath the sheds. The response time to a thread breakage is 1 milli-second, so that a very fine thread under tension crossing the beam at high speed is detected and registered. The signal is stored in a sample an dhold circuit, which also feeds through an amplifier for the stopping of the machine. The mechanism is only released when the reset button for the sample and hold circuit is pressed. The monitored width can extend to 10 m. with accessories and with a thread smaller in dia. than 0.01 mm.

Title: Flame-resistant laminate of chipboard and glued-on veneer(s) - where the glue contains a flame-retardant in a gas-permeable layer
Inventor: MENGES EDUARD ING GRAD
IPC: B27D1/04
Filed: 1976-06-28
Abstract: Flame-resistant laminates comprises a (difficulty flammable) chipboard and an adhesively bonded veneer on 1 or both sides. The adhesive layer contains a flame-retardant, and in the adhesive layer a gas-permeable layer of difficultly flammable or non-flammable material. Used e.g. in mfr. of doors, furniture, partitions. The gas-permeable layer prevents build-up of press. of gases formed during exposure to heat, inside the laminate so that destruction of the prod. is minimised or at least delayed. Normally flammable veneers can be used.

Title: Suction box for dewatering paper slurry - adapts for different widths, turns easily for redressing of sieve plate
Inventor: RAUCHMAUL DIETER
IPC: D21F1/52
Filed: 1976-08-09
Abstract: Parent patent described an installation for dewatering paper slurry consisting of a number of suction boxes with their long sides arranged parallel to each other, on the perforated horizontal plates of which, the felt with the slurry runs; there being at one end of the box suction connections to which a vacuum line can be attached. When a sieve plate shows signs of wear, the box is turned through 180 degrees and the friction of the felt redresses the plate automatically. In this addn., suction boxes are used both end faces of which have in the bottom zone on the outside of the box, easily removed tube flanges, the stubs of which have external threads. At one side the pipe connection is sealed by a cap and at the other a conventional claw coupling for the attachment of the suction pipe is provided. At the ends of each suction box under the sieve plate an adjustable plunger is fitted by which the sieve plate perforations at the ends of the horizontal plates can be blanked off. The holes at the ends, within range of the blanking plunger, are of small dia., whilst between these two zones of small holes, the sieve plate perforations are in the form of slots. A choke valve to adjust the degree of vacuum and a pressure gauge are fitted to each suction box. When it is seen that the felt is not making a seal on the sieve plate due to wear on the plate, the box can be turned through 180 degrees in the simplest and quickest possible manner. The plungers make it possible to produce paper webs of different thicknesses with the same boxes.

Title: Vulcanising mould for ring-shaped rubber blanks - has hinged segments forming working circumference without gaps or play
Inventor: PSCHINNIK LEONID GRIGORIEVITSC
IPC: B29C33/48
Filed: 1977-09-01
Abstract: A cylinder having on its outer circumference an arrangement of grooves profiled in cross-section, for receiving annular banks, forms a vulcanising mould. The cylinder is in three segments linked by hinge details so that the circumference can be reduced whilst the blanks are put on the finished mouldings are removed. The first segment is fixed and the pivoting of the other two segments hinged to it is effected by crank drives, two of which are fastened to the fixed segment. These are kinematically connected to each other so that the successive movements of the other two relatively to the fixed segment can take place. The coupling between the cranks and the hinge points on the moving segments is effected by turnbuckles. Used for the prodn. of the vee belts, etc. The segments fit accurately against each other so that axial and radial displacement of the segments is impossible and damage to the products is prevented.

Title: Insulation monitor for AC mains networks - uses differential amplifier level detector with relay output facility and includes low-pass filter
Inventor: WEUTSCHECK HEINO
IPC: H02H3/17
Filed: 1978-04-06
Abstract: The insulation monitor consists of a series-connected resistor (R1) and constant-current source (Q) connected between the AC phase (L) and earth. A capacitor is connected across the constant - current source (C1).

Title: Intruder resistant ventilated roller shutter - has interlocking flanged slats locking in side rails when pushed from below
Inventor: GOERN WALTER
IPC: E06B9/86
Filed: 1978-06-22
Abstract: Slats in the roller shutter are hung so as to interlock by means of a flange with ventilation slits in it. The blind is laterally guided in U-shaped profile rails, and each flange is thrust into the next slat, with its slit covered. Slats (10) are shaped so that when the roller shutter (14) is bunched up, a thrust from below causes locking in the rails (12) to occur. They can be wider at the bottom end (24), with a bottom attachment (34) pressing the flange (28) at the top against one rail shank (42) and the slat top (22) against the other shank (44). This prevents break-ins, and also rattling in strong winds.
