Filed: 1987-02-11
Abstract: With this device for manipulating an inoculating ladle (1), it is possible to carry out all the movements required for purifying and casting a melt effortlessly and in a time-saving manner. The device, which is arranged on the suspension yoke (7), comprises a rocker (8) mounted pivotably on the suspension yoke (7), on one end of which rocker a linkage (9, 10, 11) for opening or closing a filling cover (2) is pivoted and into the other end of which an electric block and tackle (12) is hooked. The open position of the filling cover (2) is limited by a rocker stop (7.6) arranged on the suspension yoke (7). The hook-type bottom block (12.2) of the electric block and tackle (12) is connected to a tipping bracket (5) provided at the foot (1.4) of the casting ladle. When the electric block and tackle (12) is switched on, it raises the filling cover (2) of the inoculating ladle (1) via the rocker (8), the inoculating ladle being suspended from a crane hook (13) and the suspension yoke (7), until the rocker (8) rests against the rocker stop (7.6). If the electric block and tackle (12) is switched off, the filling cover (2) remains in this open position. If the electric block and tackle (12) continues running, the hook-type bottom block (12.2) raises the inoculating ladle (1) with the filling cover (2) open and the inoculating ladle (1) is tipped about the axis (3.1) of the tipping journal (3.2) and the cast-iron melt is gradually emptied out. <IMAGE>

Abstract: The synchronous FIFO register has a three-column flip-flop matrix, which serves for the serial shifting of data bits (u, v, w) arriving in parallel. There is provided a control circuit with three control stages (C1, C2, C3), which each control one flip-flop column of the matrix and of which the central control stage (C2) receives on the input side a filling status signal F1 and a write command signal S1, which are generated by the first control stage (C1), and supplies on the output side its own filling status signal F2 and its own write command signal S2 to the third control stage (C3), the central control stage being fed an additional write command signal S3 from the third control stage (C3). In order to make the central matrix column of this FIFO register transparent in a simple way, the central control stage (C2) is configured in such a way that the following relationships apply to the said signals  S2 = (F1 + S1) . XF2  c = S2 . XTk'  F2(T>Tk') = (S2 + F2(T<Tk')) . XS3 where c is the control signal for the flip-flop column, T is a time, X is a negation prefix and Tk' is a point in time coinciding with an active edge of the clock pulse (Tk). <IMAGE>

Inventor: RICHTER EBERHARD
IPC: B27G11/00
Filed: 1987-07-08
Abstract: In order to glue saw-toothed abutting surfaces (1) of strip-shaped veneer pieces (2 and 3) to be joined to form veneer blanks, the front abutting surfaces (1) and hence the teeth (4) are in each case wetted with glue by arranging the two veneer pieces (2 and 3) at a distance from one another with one flat side and teeth (4) pointing towards one another on an application surface (7), an apportioned strip of glue (6) or, alternatively, a series of spots of glue being applied in the space between the two mutually facing front sides of these veneer pieces (2 and 3) to be joined, before, at the same time as their arrangement or, alternatively, afterwards, and at least one veneer piece then being moved towards the other and in the process being pushed through the glue with its teeth (4). In this process the moved veneer pieces(s) (2 and 3) is/are guided on their top side (10) facing away from the application surface (7) having the glue and are held down to such an extent that they are prevented from sliding over one another. The intermediate transport of the veneer blanks after the wetting of the abutting points with glue is thus avoided and the wetting with glue and the joining together take place on one and the same apparatus. <IMAGE>

Patent DE-3728201-A1 (DE)
Title: Soil-cleaning method and appliance for carrying it out
Inventor: KANCZAREK THADDAEUS-ANTON DIPL
IPC: B03B1/00
Filed: 1987-08-24
Abstract: The soil-cleaning method and the appliance for carrying it out are based on the fundamental idea of a directed superimposition of two motion components of the soil particles with very high acceleration forces which lead to the detachment of clinging harmful substances. To this end, the soil and the washing solution are fed as a suspension (30) into a channel-shaped treatment chamber (BK). The latter can be designed in particular as a pipeline for a continuous process. The suspension (30) is set in rotary motion (u, u') by high-pressure fluid jets (7, 7', 71, 72, 73), produced by jet nozzles (50) in a nozzle wall (2). The primary rotary motion (u) contains microturbulences (u') of different speed profiles in which the soil particles, the size of which is in the  mu m range, correspondingly move in a rotary manner. A superimposed longitudinal movement, produced by ultrasonic pressure waves (4) of corresponding ultrasonic transmitter heads (3), forces the soil particles into zones of different radii and thus different peripheral speeds of the circulating flow (u). The soil-cleaning method is suitable for carrying out on the spot with a corresponding mobile appliance, in which the treatment chambers consist of a multiplicity of pipelines connected parallel to one another. <IMAGE>

Title: Method and device for regulating a direct current using D.C. controllers connected in parallel
Inventor: BOEHRINGER ANDREAS PROF DR ING
IPC: H02M1/088
Filed: 1988-05-14
Abstract: In the case of a method for regulating the direct current supplied to a load, using a parallel circuit which is in series with the load and comprises at least two D.C. controllers, the D.C. controllers are prepared for a switching state alteration successively in a constant sequence, which is repeated cyclically at a predetermined clock frequency. On each clock pulse, a decision is made, only for the D.C. controller prepared for a switching state alteration, as to whether to keep or alter its switching state. The device for implementing this method comprises, for each D.C. controller (2), a logic circuit (8) having a first input and a second input. Each of these first inputs is connected to the output of a signal generator (11-13), the signal of which determines the switching state. In addition, a clock pulse generator (9, 10) is provided, having a number of signal outputs corresponding to the number of D.C. controllers (2), on which outputs a clock signal is present, successively in a constant sequence, which is repeated cyclically at a predetermined clock frequency. The second input of the logic circuits (8) is in each case connected to one of these outputs. <IMAGE>

Title: Process for producing a microporous polyamino acid urethane resin film
Inventor: ITO NOBUO
IPC: D06N3/14
Filed: 1988-05-16
Abstract: The present invention relates to a process for producing a microporous film which is superior with regard to moisture permeability, heat resistance and elasticity and is obtained by the dry process and use of a water-in-oil emulsion of a polyamino acid urethane resin solution. The conventional polyurethane resin was superior in physical properties, such as elasticity and low temperature resistance, but a microporous film obtained from this resin shows disadvantages in properties such as moisture permeability and heat resistance. The present invention was made as a result of research concerned with improving these disadvantages, and creates a process for producing a microporous polyamino acid urethane resin film which is characterised in that an alkyl ester group in a polyamino acid urethane resin obtained by the copolymerisation of a urethane prepolymer with a terminal amino group and an acid amino acid alkyl ester N-carboxylic anhydride in an organic solvent was reacted on at least one kind of ammonium, hydrazine, monoamine and diamine in order that a hydrophilic property may be conferred, and then a water-in-oil emulsion of the polyamino acid urethane resin obtained by adding water to the resin solution was applied to a substrate and dried.
Patent DE-3817525-A1 (DE)
Inventor: WEIGEL JUERGEN
IPC: B29C43/14
Filed: 1988-05-24
Abstract: The invention relates to a method for producing a shell-like moulded article, the walls of which are formed in a positive and/or negative mould from a fibre-reinforced supporting layer of a liquid synthetic resin with hardener and at least one top coat of a modified, liquid synthetic resin, arranged on one side of the supporting layer and bonded integrally to the same. In order to develop this method in such a way that less work is involved in producing the top layer and the styrene emission is considerably reduced, as well as allowing the possibility of applying the top or gel coat subsequently to the already produced supporting layer, it is proposed that a deformable space is formed between the mould and the supporting layer, that a predetermined quantity of liquid synthetic resin required for the top coat is filled into the space and that this space is subsequently deformed by pressure and/or vacuum and the top coat thereby formed. <IMAGE>
