Inventor: LEATHERMAN ALFRED FULLER
IPC: H05B6/06
Filed: 1989-07-21
Abstract: An integrated multiple particle heating agent (3) is provided for heating, particularly using the agent for heating and bonding plastic substrates. The integrated multiple particle heating agent (3) includes significant portions of non-conductive ferromagnetic oxide particles (9) which generate heat because of hysteresis losses and of conductive ferrous particles (10) which generate heat because of eddy current losses. The dual particles are thoroughly intermixed and respond to a magnetic field (8) of an appropriate RF frequency. The ferromagnetic particels (9) are submicron size and the ferrous particles (10) are micron size. The particles are combined with an inert resin carrier (4) and applied as a coating, directly incorporated within the substrate, or as a separate element. The ferromagnetic oxide loading is generally less than the ferrous particle loading, with a range of 30 to 60 percent (40 to 50 preferred) by weight of ferrous particles and a range of 10 to 50 percent (15-25 preferred) by weight of the oxide particles. The radio frequency magnetic field can be in the range of 1,2 to 7 MHz with 3,5 to 4 MHz being typical. The integrated submicron sized ferromagnetic particles (9) and micron sized ferrous particles (10) generate heat at a significantly and unexpectedly high rate using a single RF magnetic field (8) of a relatively low frequency. The percentage loading may vary with different substrates.

Abstract: A wet recording apparatus, using a developer (7) with a charged colorant dispersed in a dispersion medium, has a plurality of electric field generators (4, 5) to which a voltage is selectively applied, and a developer feeder (9), feeding the developer into a gap formed between said field generators (4, 5) and a recording paper (1) whereby a colo­rant image is formed on the recording paper according to the electric field established by said field generators. Each field generator comprises a recording electrode and a counter electrode (5) provided on a side of the recording paper (1) of opposite to the recording electrode. The re­cording electrode may be constructed of a main electrode and an auxiliary electrode. In such construction, a static latent image former is not required, and a charged pigment in the developer moves to stick onto the recording paper through electrophoresis under the electric field formed by the field generators. The quantity of the sticking pigment may be continuously controlled by the intensity of the electric field and voltage impressing time, and since a picture image is reproduced directly on the recording pa­per, a high picture quality is obtainable.

Abstract: In a computer system, a series of parallel input circuit lines are connectable to each removable/-­replaceable circuit card or other component for carrying preliminary sequential polling signals. A single configuration bus is connected to the output of passive circuit components located in such circuit card or other component. A unique identification number encoded in such passive circuit components is transmitted along the configuration bus to a com­parator whenever the slot holding such circuit card is polled by a query signal. Thus, improper circuit components and/or improperly located circuit com­ponents are detected before any power is applied to the system.

Abstract: The electrical safeguard device for a clamping device is represented on a sheet transfer drum for printing machines for optional first impression printing or perfecting. The actuating member (27) of the clamping device is arranged so that it can be screwed axially between end positions by a thread, the screwing movement on a first portion actuating a switching member (28) for an electric switch (30) lying in the power supply circuit for the drive of the printing machine. During its movement on a second portion, the actuating member (27) acts on intermediate elements which press at least one friction surface on the sheet transfer drum against a friction surface on a part of the sheet transfer drum which is adjustable in the circumferential direction. The end positions are limited by stops consisting of a cam (32) on the actuating member (27) and two cams (33a, 33b) on a part of the machine which is arranged fixedly in terms of rotation, the two cams (33a, 33b) each being assigned to an end position and having a spacing in the direction of the axial displacement of the actuating member (27), which spacing is greater than the pitch of the thread, and the axial covering of the cam (32) on the actuating member (27) by one of the two other cams (33a, 33b) in the stop position being smaller than the pitch of the thread.

Abstract: A hydraulically damped mounting device has two anchor parts (1,3) joined by a resilient spring wall (9). The resilient spring wall (9) and a partition (6) define a working chamber (13) for liquid, the working chamber (13) being in communication with a compensation chamber (14) via a passage (73,74,75,76). The compensation chamber (14) is bound by a flexible bellows wall (5). A flexible diaphragm (66) of annular shape defines, together with the partition (6), a gas chamber. The annular nature of the diaphragm (66) means that the centre of the partition (6) which bears the most load during relative vibration of the anchor parts can be made strong.

Abstract: An improved electric device and manufacturing method for the same are described. The device is for example an IC chip (28) with associated leads (39) encapsulated within a moulded plastics package (41). In advance of the moulding process, the IC chip (28) and its associated lead structure (39) is coated with silicon nitride (27) or other electrically insulating material in order to protect the IC chip from moisture invasions through cracks or gaps in the encapsulation. The coating of the silicon nitride is advantageously carried out after cleaning of the surfaces of the IC chip and its associated structures by plasma cleaning in a plasma CVD apparatus which is then utilized for the silicon nitride coating process.

In response to the output signal of the comparator, a control circuit (9) produces the control signal to be supplied to the power supply by adding the output signal of the comparator to a predetermined signal to control the electric power outputted from the power supply to the laser.

Abstract: The invention relates to the piecing of the roving to an empty roving bobbin within the bobbin change on automated fliers. The aim of the invention is to contribute to increasing the degree of automation of the flyer and ring spinning machine. The object on which the invention is based is to provide a method for the automatic piecing of roving to roving tubes, which, without a high outlay, makes it possible to produce roving bobbins having a winding commencing in the vicinity of the tube foot. This object is achieved, according to the invention, in that, during the introduction, the roving tube is set in rotation opposite to the winding direction, until the press finger has reached the piecing position located in the immediate vicinity of the tube foot, and in that the direction of rotation of the roving tube is then reversed and the roving start guided in the press finger is applied to the roving tube. <IMAGE>

Abstract: A system for controlling the running state of a motor vehicle comprises a traction control apparatus for controlling the traction or driving force of the motor vehicle, and a speed control apparatus for regulating the vehicle speed to correspond a predetermined speed setting. The speed control apparatus is connected with the traction control apparatus via a signal line, and includes speed control correcting means. The speed control correcting means inhibits the speed control apparatus from outputting an operation signal to open a mechanical throttle valve of the vehicle, and also inhibits the provision of a down-shift signal to an automatic transmission so long as the traction control apparatus outputs a traction control signal. Additionally, the speed correcting means commands the speed control apparatus to output a signal so as to only slowly return the mechanical throttle valve when the operation of the speed control apparatus is interrupted while the traction control apparatus outputs a traction control signal.
