Patent FI-925716-A (FI)
Inventor: GERSTENKORN BERNHARD
IPC: E05F15/632
Filed: 1992-12-16
Abstract: A method for controlling a sliding door system determines the masses and the frictional forces of all movably interconnected parts of the sliding door system. The system has a door leaf which is moved in an opening learning travel and a closing learning travel and guided without drive over respective first and second test sections. First and second energy balances are determined from the detected speed and distance travelled data of the first and second test sections respectively. The energy balances equate the kinetic energy at the beginning of a test section with the kinetic energy at the end of the test section plus the frictional energy plus the potential energy of a closing weight connected to the door leaf. The potential energy is added with a positive sign for opening travel and a negative sign for closing travel. The dynamic mass and the mean frictional force of the sliding door system can then be determined from the first and second energy balances. An apparatus for controlling the door motor in accordance with the method includes a microprocessor in a door drive with a memory for storing the speeds and distances associated with the learning travels. The microprocessor and the tachometer detect, store and process the speed and distance data, and the microprocessor determines the values for the dynamic mass and the mean frictional force and also the closing speed, which is the maximum permissible for safe operation of the door.

Patent FI-961985-A (FI)
Inventor: TCHAMOV NIKOLAY
IPC: H03K3/282
Filed: 1996-05-09
Abstract: An emitter-coupled multivibrator oscillator circuit including a pair of main transistors (Q1,Q2) having a positive feedback, in which the base of each transistor is connected to the collector of the other transistor via buffer transistors (Q3,Q4). A capacitor (C) is connected between the emitters of the main transistors. The circuit further comprises pull-down transistors (Q5, Q6), cross-connected so that they are positively driven to alternate between a conducting and a non-conducting state according to the states of the main transistors. The frequency of the oscillator is adjusted by controlling the current (I1) passing through the capacitor (C). Additionally, a compensating current (Icom) is arranged to flow through the collector resistors (Rc1,Rc2) of the main transistors so that the total current passing through each resistor is essentially constant and independent of the control current (I1). This way the signal amplitude of the oscillator is not affected by the frequency control.

Abstract: 538,128. Coating with metals. JOHNSON BRONZE CO. Jan. 20, 1940, No. 1233. Convention date, May 22, 1939. [Class 82 (ii)] [Also in Group XXII] Steel-backed lead-bronze bearings are made by grinding pre-cast bronze to a fine powder, applying this to a steel backing, and heating the whole in a non-oxidizing atmosphere. A strip of steel is cleaned and preferably coated with zinc chloride or other flux or plated with tin or copper. The bronze is ground so as to pass an 80-mesh sieve but not a 200-mesh one and may be sintered at 1300‹ F., in a reducing atmosphere, with a finer powder of copper to roughen the surfaces of the bronze particles or be merely mixed with such powder of copper, tin, zinc, aluminium or other metal. This powder is preferably applied and spread, 0.045-0.055 of an inch thick, by a mechanism through which the strip is fed. This is then passed through a hydrogen or other reducing or neutral furnace at 1250‹- 1500‹ F. The strip is then cold rolled, to reduce the thickness of the bronze to 0.025 of an inch, passed through another and similar furance, and finally cold rolled to reduce the thickness of the bronze to 0.005 of an inch and harden it. The strip can then be cut up and stamped. Graphite or other solid lubricant may be mixed with the bronze powder and, if the bronze layer is not consolidated too much by rolling it may be impregnated by dipping in oil. Specification 509,834, [Group XXII], is referred to.

Title: Improvements in or relating to electric power systems
IPC: H02P9/00
Filed: 1939-01-13
Abstract: 523,755. Transmitting mechanical power. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Jan. 13, 1939, No. 1255. Convention date, Jan. 28, 1938. [Class 38 (iv)] In a system in which a prime mover drives a main electrical generator, an exciter and an auxiliary generator, the means for controlling the prime-mover also operates a generator regulator system by which, over the lower speed range, a differential control is exerted on the exciter to limit the torque on the prime mover, while, over the higher speed range, the field of the generator is controlled so as to attain maximum torque. The auxiliary generator may function as a speed indicator and controller over the higher range and also serves to charge a battery and drive auxiliaries. The primemover 22 is directly coupled to the generator 9, the exciter 13 and the auxiliary generator 17, and is regulated by control lever 33 connected to switch contacts 35, 34 by which the two control ranges are rendered effective. For starting the prime mover, switch 37 and push-button switch 39 are closed thereby supplying current from the battery 24 to the starting field 12 of the generator. When the engine is started, switch 38 is closed, whereby relay 27 and voltage regulator 25 are energized thereby connecting regulating resistances 45, 46 in or out of the circuit of the shunt field 21 of auxiliary generator 17 to secure constant voltage for charging the battery 24. When the prime mover is driven up to about half speed for supplying the motor 23, contacts 34 are closed by control lever 33, thus energizing relay 36 by which the field 15 of the exciter 13 is connected across the battery, whereby the exciter 13 energizes the field 11 of the main generator 9. Variations of the current in the main circuit between the generator 9 and the. motor 23 act through the opposed or differential field 16 of the exciter to limit torque resistance of the generator. When running at higher speeds the engine control 33 also closes contacts 35 thereby operating relays so that controller 25 is de-energized and controller 26 is brought into operation by connecting its winding across the auxiliary generator 18. The voltage of this generator 18 then varies with the speed and it controls the operation of relay 26 by which switch 29 is opened or closed to regulate the resistance in the field 11 of the main generator 9 and secure maximum torque at all speeds.

IPC: B65D65/38
Filed: 1951-01-17
Abstract: A moulded packing unit which is resilient and permeable by air is made of lightly compressed woodwool, wood shavings, shredded wood, cereal straw, hay, dried grass, or flax rug which is flax mechanically broken down, or a mixture of two or more of these materials, held together by a thermosetting adhesive.  Wood wool sprayed with synthetic resin, e.g. of the phenol formaldehyde or urea formaldehyde type, using for example 1/2 lb. resin to 3 1/2 lbs. wood wool, is evenly distributed between a central perforated pattern, of the shape of the portion of the article to be enclosed by the packing unit, and external perforated platens. The platens are pressed at about 45 lbs./sq. in. to consolidate the material and hot compressed air (pressure about 1 lb./sq. in., temperature 210-230 DEG F) is passed through the central pattern and the moulded material therearound, causing the resin to set.  An article may be protected by a two part packing unit.  A filler such as wood chips or sawdust up to about 50 per cent. by weight of the moulding material such as cardboard or fabric may be placed in the wood wool while it is being distributed round the pattern prior to moulding under pressure.

Filed: 1925-01-16
Abstract: 228,153. Patart, G. L. E. Jan. 21, 1924, [Convention date]. Air and gases, moistening.-In a vertical column divided into two parts through which water is continuously circulated, fresh reaction gases are heated and saturated with water vapour in the lower part, whilst in the upper part the reaction products are cooled and their water content condensed. At the base of the column is a regulating reservoir 17 in which water is maintained at a constant level by means of an overflow 21 and cold water supply 22. The water is delivered by the pump 19 through the tube 20 to the top of the upper part 3 of the column, whence it falls down bubbling plates, coke, &c., in the upper part and becomes heated at the expense of the hot reaction products from a catalyser 9 entering by the pipe 10 and leaving by the valved pipe 24, the gases being at the same time cooled and deprived of most of their water vapour content. The hot water then passes through the siphon tube 15 to the lower part 4 of the vertical column, where it meets the fresh gases for the catalyser which enter by the valved pipe 2 and leave by the pipe 5, and in descending the bubbling plates, coke, &c. the water delivers up its heat to the fresh gases which are at the same time saturated with water vapour. Additional water vapour required for the reaction in the catalyser 6 is supplied by a steam injector 7, whilst the power required for circulating the gases is derived from one or more centrifugals 6. The apparatus is intended for use in the catalytic manufacture of hydrogen from steam and carbon monoxide. Specifications 15498/02 and 136,189 are referred to.
