Title: Ceramic-ceramic or ceramic-metal composite powders having uniform 2nd - obtd. by cation-exchanging metal from soln. onto ceramic powder then converting metal to cpd.
Inventor: OHTSUKA KUNIO
IPC: C01F7/02
Filed: 1990-07-19
Abstract: An inorganic powder having a cation-exchange property is formed into a suspension with a metal-contg. soln. where metal ions are exchanged into its surface. A precipitant-forming material which releases an anion when subjected to heat or pressure is then added and heat or pressure applied so that the released anion forms metal hydroxide, salt or basic salt on the surface of the particles. The composite powder is heated to convert the metal cpd. into oxide, producing a ceramic-ceramic composite material. Opt., the metal oxide may be reduced to yield a ceramic-metal composite powder.

Title: Current supply for alternating voltage fluctuation control - has transformer with tappings for different input voltages which are selected across logic circuit and connected using switches
Inventor: SIMMANK WILFRIED
IPC: H02M5/12
Filed: 1991-07-26
Abstract: The current supply has a transformer which can have one or more output windings. In the event that no separation from the mains is necessary, an autotransformer can be used. Electronic switches as well as mechanical switches can be used for switching e.g. triacs and relays. The tappings selected across a logic with switches are on the output side. Simultaneous zero passage of current and voltage takes place only with a pure ohmic load. Therefore, it is necessary that triacs are not switched off and simultaneously other triacs are switched on in the zero passage of the voltage. So that switched off triac yet still conducting can cause a short circuit. USE/ADVANTAGE - Can be used where high output voltage accuracy is not required. Fluctuations of main voltages can be balanced and feedback coupling from output can reduce load influence. Higher accuracy obtained with output regulation.

Patent DE-4203131-A1 (DE)
Title: Bleaching fibrous material - uses gas reagent suspension with opened fibres for mechanical mixing for reaction and porous bed to complete reaction and remove surplus gas
Inventor: CARLSMITH LAWRENCE A
IPC: D21C9/153
Filed: 1992-02-04
Abstract: Fibrous material is opened out within the gas reagent to form a gas suspension with the fibres. The material is mixed mechanically while in suspension with the gas reagent, until it has reacted with the fibres. The material is passed to a porous bed for gas to be extracted to finish the reaction and ensure that all surplus reagent is removed from the fibre material. The assembly to move the gas suspension of fibres has a longitudinal mixing chamber with a number of mixing paddles on a rotating axial shaft. A screw conveyor at the entry to the mixing chamber moves the gas and fibre suspension into the mixing chamber at a speed which gives the gas suspension a dwell time of up to about 10 secs. After the gas/fibre suspension has been fed into the mixing chamber it dwells in the chamber while mixing for a sufficient time to allow the major portion of the gas reagent to react with the fibres. The gas/fibre suspension is transferred into a degassing and reaction chamber to form a porous bed, where the reaction can continue until the reagent is wholly consumed. The fibre material is opened out with the gas reagent, using wood pulp with a consistency of 20-50%, and the reagent is a mixture of ozone in oxygen, with a dwell time of about 10 secs. in the mixing chamber. The screw conveyor generates a movement pressure against the mixing paddles in the mixing chamber, and gives a dwell time of about 10 secs. for the pulp gas suspension in the mixing chamber. USE/ADVANTAGE - Partic. to bleach pulp for use in papermaking, using gas reagents such as chlordioxide or ozone. The technique gives a thorough reaction between the gas and the fibre material, with lower reagent consumption

Inventor: KIM CHEOL-MIN
IPC: H04N5/445
Filed: 1992-03-19
Abstract: Since channel changing causes noise in synchronization, and an unstable picture when performing automatic frequency tuning (AFT) and automatic gain control (AGC), an image signal of the previous channel is stored in an image memory 80 before being changed, and output onto the screen using a switch 50 controlled by a microcomputer 20 during the unstable period of AFT and AGC, instead of the image signal of the altered channel. The image signal of the altered channel is output after the output of an automatic controlled is stabilized. <IMAGE>

Title: Blocking capacitor prodn. from metallised films - includes non-self healing films, by demetallisation of cut edges using laser beam
Inventor: FERAL THIERRY
IPC: H01G13/06
Filed: 1992-04-01
Abstract: A healing process which can be incorporated into the prodn. of blocking condensers from flexible, metallised films of all types, and not just those such as polyethylene terephthalate or polypropylene which are self-healing, involves scanning the cut film edges with a laser beam at an angle of incidence of 0-70 deg. so that non-metallised edges (9) are formed on all of the film layers of the semi-finished condenser. USE/ADVANTAGE - The healing process can be applied to polyester, polycarbonate, polysulphide, polypropylene or other plastics films metallised with e.g. Al, Zn, or Cr and cut with simple appts. The metallisation is thermally removed, pref. to give a metal free edge zone some 1/10-1/20th of the film breadth, this resulting in an improvement in resistance to edge sepn. and a high dielectric strength for the final prod. In subsequent processing of the condenser the conventional hardening temp. of 145 deg.C can be raised to 180 deg.C.
Patent DE-4214541-A1 (DE)
Inventor: GOTTSCHALK ACHIM DR ING
IPC: B61L17/00
Filed: 1992-04-29
Abstract: For the online determination of the rolling resistance of a train section, the actual running path/running time behaviour of the section is recorded during freewheeling; during this process, the times when individual axles of the section pass over contacts are determined. In addition, the computational time points when the contacts are passed over are determined from the simulation of the process. If the actual running behaviour of a section deviates from its computationally calculated running behaviour, false values for the variables taken into account in a simulation model are set in the simulation model. By listing the numerical values for the influence which changes to these variables have on the computationally calculated times of passing over contacts, in a matrix and application of the orthogonalisation method to this matrix, correction values for the variables are obtained. Using these correction values, new times of passage over the contacts and new values for the influence of parameter changes are determined and, from these, new correction values are determined again for the variables. These processes are repeated until a sufficiently accurate adaptation of the computationally determined running path/running time behaviour to the appropriate running path/running time behaviour is obtained. The value of the rolling resistance which is then used for the simulation gives the actual rolling resistance of the train section in question. <IMAGE>

Title: Section warping machine - uses a head-shaft arrangement to enable ties to be placed on the tapes automatically
Inventor: BUTTERMANN GUENTHER
IPC: D02H9/00
Filed: 1992-07-18
Abstract: A process to tie the tapes on a section warping machine, in which the yarn from a creel is brought through a heald-shaft arrangement is claimed. When the drum is stopped, the yarn is sepd. and the tie introduced through the shed which is formed. The tie is introduced automatically near the expanding reed, and carried to the drum before the shed closes. The appts. is also claimed. The yarns (13) are drawn in a bundle from the creel and are sepd. in the reed (33) to prevent entanglement. When the drum is stopped, the expanding reed (18) is moved to a position (68) behind the tie insertion mechanism (20) by means of the mechanism (28). The heald-shafts (14) separate yarn sheds (15), to enable the mechanism (20) to insert a thread (10) across the width of the tape. The shaft mechanism changes the shedding, and a second thread (10) is inserted. These are cut off, but with sufficient width to enable the ends to be knotted. It is then carried forward by the expanding reed (18) to the drum (17) and set in the correct position, with the correct width, before the shed is closed. ADVANTAGE - The tapes are tied automatically without manual assistance, and therefore the operation is carried out quicker.
