Abstract: Apparatus for and methods of forming airlaid fibrous webs having a multiplicity of layers and/or discrete particles of absorbent gelling material dispersed through at least a portion of the web. The apparatus (20) is of the type which includes an airlaying means (34,46) such as a laydown drum (100,110) having a foraminous forming element; a first or primary deposition means (36) for directing a first or primary stream (54) of air-entrained fibres to the laydown drum (100); a first or primary hood (38); a dusting layer deposition means (42) for directing a dusting layer stream (56) of air-entrained fibres to the laydown drum (100) wherein the dusting layer stream is deposited onto the laydown drum (100) prior to depositing the first or primary stream (54) on the laydown drum (100) and a dusting layer hood (44). The dusting layers (1012) acts to block the passage of particles or fibres entrained in the first fibre stream (54) so as to minimize equipment plugging problems and the loss of particles or fibres through the foraminous forming element. In addition, the first vacuum chamber (126) in the laydown drum (100) spans the first hood (38) and a portion of the dusting layer hood (44) so that the dusting layer (1012) is not sheared off, damaged, or destroyed as the laydown drum (100) rotates to the position where the first fibre stream (54) is deposited over the dusting layer (1012). 
     The method preferably comprises the steps of:
     a. providing multiplicity of streams (54,56,58) of air-entrained fibres:   b. directing a dusting layer stream (56) of air-entrained fibres to an airlaying means (34);   c. forming a dusting layer (1012) on the airlaying means (34) from the dusting layer stream (56) of air-entrained fibres;   d. directing a first stream (54) of air-entrained fibres to the airlaying means (34);   e. forming a first layer (1014) over the dusting layer (1012) on the airlaying means (34) from the first stream (54) of air-entrained fibres.

Abstract: A remote control system (1) remotely switches an electric power supply (8,6) to the display section (4) of a display apparatus whose display data control section (2) and display section (4) are located far from each other and separately supplied with power from their respective local commercial power sources. The control system (1) comprises an oscillator (11), a counter (12) adapted to output a switch opening signal after counting out a predetermined number of pulses output from the oscillator (11), and a relay switch (13) inserted in the power supply (6,8) to the display section (4) and adapted to be opened by the switch opening signal from the counter (11). The counter (11) receives                               at its reset terminal (R) the clock signals transmitted to the display section (4) from the control section (2). While the control section (2) continues to output the clock signals, the counter (12) does not output the switch opening signal, and the relay switch (13) remains closed. If the clock signals cease for a predetermined period of time, corresponding to the predetermined number of clock pulses, the relay switch (13) is opened, thereby cutting off the power supply (6,8) to the display section (4).

Abstract: A capacitance sensor arrangement is used to determine the distance of an element such as a shearing handpiece from a surface such as the skin of a sheep. The arrangement processes data from one or more sensors (SL, SR, SB) which include a variable capacitor (C x ) dependent on the distance, and provides an output voltage (V S ) consistent with the distance, the output voltage (V S ) being dependent on the voltage drop across a reference capacitor (C L ) in the sensor circuit.

Abstract: Signals from transmitter stations are connected to receiver stations by a switched optical network. To provide a readily expandable, non-blocking network for a large network, groups of transmitter signals are formed into distinct optical wavelength multiplexes each of which is coupled by an optical fibre bus (4) to one input of each of several optical space switches (SW). Each receiver station is connected to an optical heterodyne receiver optically coupled to an output of one of the optical switches (SW). The required signal from the multiplex switched to an optical receiver is demultiplexed by combining with the multiplex an optical source (O) which has been frequency shifted by a frequency shifter (12). This is achieved by means of a secondary optical space switch (SW′) and an optical combiner (14). The optical space switches (SW, SW′) are controlled by a controller (6) to effect the desired connection.

Abstract: L'invention concerne un nouvel alliage à base de palladium. Cet alliage à base de palladium est caractérisé en ce qu'il comprend de l'étain en quantité suffisante, de préférence 5 à 20 % en poids, pour conférer une résistance à la corrosion par le verre fondu acceptable, de préférence sensiblement équivalente à celle des alliages platine-rhodium 10 %. Un tel alliage est utilisable dans l'industrie verrière pour la réalisation de pièces en contact avec le verre fondu, qui est de préférence sensiblement exempt d'oxyde moins stable que l'oxyde d'étain, comme l'oxyde plomb, car il présente une résistance à la corrosion par le verre fondu excellente et est d'un coût beaucoup moins important que l'alliage habituellement utilisé platine-rhodium 10 %. En outre, par l'addition d'au moins un élément parmi le platine (0-50 % en poids), le rhodium (0-20 % en poids), l'iridium (0-20 % en poids), le ruthénium (0-20 % en poids), on améliore de manière significative la résistance mécanique à chaud, notamment la tenue au fluage.

Abstract: The conveyor chain assembly is made of multiple rows of pivotally connected link modules (14). Each module (14) has spaced link ends (20,22,26) which project between the link ends (20,22,26) of the module (14) in the adjacent row. The joint between modules (14) in a row is straddled or bridged by a module (14) in the adjacent row to give a bricked lay-up. Each of the modules (14) on the left side of the conveyor has a solid link end (20,22) so the pivot rod (24) abuts the inside of the link end (20,22). The other end of the pivot rod (24) lies just inside of a spring plug (28) mounted in the arm or link end (26) on the right side module (14). The modules (14) cannot be end-for-ended and assembled. They must be assembled correctly. Certain link ends are wider than the others to require proper assembly to the modules (14) in the adjacent row and to distribute drive loads over a greater area. Both sides of the conveyor are essentially flush or smooth.

Date Jun. 16, 1988.A method and device for controlling a bridge circuit for providing current or power to a load. The bridge comprises two transistors including flywheel diodes and connected in series between positive and negative power supply rails for conducting current to or from the load under control of a control drive circuit. An LC-circuit is connected between the bridge circuit and the load. The bridge voltage (E) of the connection between the two transistors and the current (I) through the inductance of the LC-circuit are monitored and a firing pulse is supplied to one of the transistors. When the current (I) through the inductance exceeds a preset value (I'), the transistors is turned OFF, whereupon the current of the inductance continues to flow another way through the flywheel diode of the opposite semiconductor member and consequently the bridge voltage (E) changes polarity a first time to the opposite rail polarity until the magnetic energy of the inductance has been terminated resulting in a second change of polarity of the bridge voltage (E) towards the first rail polarity. The change of the polarity of the bridge voltage (E) towards the first rail polarity is detected and another firing pulse is supplied at or shortly after said change.
