Patent EP-0384625-A1 (EP)
Inventor: CASTRICUM WILHELMUS P H
IPC: B26D1/60
Filed: 1990-02-12
Abstract: An apparatus for forming and slitting spirally formed pipe, particularly spiral pipes having a diameter of approximately one inch or less, is disclosed. The pipe forming apparatus includes an enclosed forming head (29) and a mandrel (60). A continuous strip of metal (15) is driven around the mandrel (60) and inside a lateral bore (30) in the forming head (29) in a helical manner. First and second rollers (37,39) mounted in the forming head partially form a spiral lockseam. A third roller (52) mounted in the upper portion of the forming head closes the spiral lockseam. The mandrel (60) is both rotatable and pivotable. The device for slitting the spiral pipe into sections includes a first knife (80) that is positioned inside the spiral pipe. This knife is mounted at the end of a rotatable boom (81), that extends through the mandrel and is positioned inside of the spiral pipe. A second rotatable knife (110) is positioned outside of the pipe. A rotatable support roller (130) is also positioned outside of the pipe, and opposite the outer knife. To cut the pipe, the outer knife punctures the pipe and overlaps the inner knife, and the support roller abuts the opposite side of the pipe. The inner and outer knives and the support roller move axially with the pipe. As the pipe continues to rotate, it is completely severed.

Abstract: A numerical insulation tester (10) consists of a digital signal processor P1 intended for the real-time tabular synthesis of a sinusoid. The numerical values of the sinusoid are sent to a digital- analogue convertor CNA of an injection circuit (48) in order to generate a low frequency AC reference signal with a very low and stable level of phase distortion. A data acquisition circuit (50) is provided with a switch (52) cooperating with a double measuring circuit (38, 44) to send an injected voltage signal and a leakage current signal into an analogue low-pass filter (56) connected in series with a sample-and-hold circuit (58) and an analogue-digital convertor CAN. The processor P1 then carries out synchronous demodulation and sends the data to a microcontroller P2.

Abstract: The device combines heating, ventilating or air-conditioning aeraulic and thermal equipment with a technique for distributing air using novel constituents in this application. The device eliminates the equipment of the duct or plug type which are characteristic of whole-air conditioners. It creates a horizontal technical duct which is accessible and demountable and is available over the totality of the surface of the premises. A ventilation unit (1) blows, above a false ceiling made of impervious stretched fabric (2), the air pretreated in the power unit (1). This air (8) is distributed and retreated by transfer modules (3) towards the blowing volumes above a false ceiling made of permeable fabric (4). The latter provides the homogeneous distribution of the air (8) over the entire surface of the treated premises (5). A recovery grille (6) provides the recycling of air (8) towards the circulation room (7). <IMAGE>

Abstract: An IR suppressor produces a thin "ribbon" exhaust plume using a tapered exhaust manifold (3) which has a plurality of discrete exhaust nozzles (6) that are longitudinally aligned with the exhaust manifold (3). Optionally, the nozzles (6) extend with­in but are spaced apart from mixing ducts (15) which are open to the ambient air at both ends. The mixing ducts (15)mix ambient air with the exhaust plume. For use in a helicopter the IR suppressor is rotatable so that the exhaust can be directed substantially parallel to the helicopter blades when the blades are not turning to protect them from exhaust heat.

Abstract: The multiplexer comprises n (an arbitrary integer) multiplexing circuits (11 to 1n) that converts signals input from multiple circuits into m (an arbitrary integer) parallel signals having a first .. transmission speed to which an additional bit is added, a `parallel-serial converter circuit (40) and buses (30) that connect n multiplexing circuits and the parallel-serial convert circuit together. Each of the n multiplexing circuits has a circuit that successively sends the m parallel signals onto the buses using pulse signals of a second transmission speed which is n times as fast as the first transmission speed. A digital signal separator comprises a serial parallel converter circuit (75), n (an arbitrary integer) separating circuits (51 to 5n) that separate the additional bit from the m parallel signals of the serial parallel converter circuit (75) and sends the signals onto circuits at a predetermined speed, and buses that connect the serial-parallel converter circuit (75) and the n separating circuits together. Each of the separating circuits receives signals from the serial parallel converter circuit sent onto the buses at a clock timing of the same speed as the predetermined tranmissionn speed. @(58pp Dwg.No.3/19)@.

Abstract: This invention relates to a magnetic recording/reproduction apparatus such a VTR, DAT, and the like. A cue signal is recorded in advance as a position mark for making an automatic operation or automatic edition along with the contents of a program. The frequency of the cue signal is selected in an audio signal band. The cue signal is recorded along with audio signals in a time-division multiplexing way on an auxiliary audio track (24) of a magnetic tape (21). A silent zone is disposed before a cue signal recording region, and a cue signal is judged to be a correct one when the cue signal is detected by a filter after this silent zone is detected. A counter (6) determines the frequency ratio between the cue signal and a control signal (CTL). The CPU (7) discriminates the cue signal on the basis of this frequency ratio. A reproduction signal is divided into blocks and the cue signal is detected from the frequency distribution of the frequency. The present invention makes it possible to improve the efficiency of recording and reproduction of the cue signal, simplify the detection structure and make correct detection.

Abstract: The intensity of light reflected from the surface of coffee beans which are being roasted is continuously measured on the one hand at two wavelengths which are absorbed by water and on the other hand at two wavelengths of which only one is absorbed by water, the other not. In the first case, the degree of roasting (colour) of the roasted product is measured, controlled by means of this and if necessary terminated if the colour of a preset colour standard is achieved. In the second case, the surface moisture is first measured at the surface of the coffee beans and the preset moistening is then carried out directly after roasting, taking into consideration the colour change (becoming darker). By this means, the need for test roastings, and experimental determination of the amount of water to be added, is avoided.

Abstract: A horizontal deflection system (20) comprises a horizontal deflection yoke (Lh) and a resonant retrace circuit (24) coupled to the yoke (Lh) and to a switched energy source (Q2) for generating a horizontal deflection current (Ih) in the yoke (Lh). A diode modulator (12) is coupled to the resonant retrace circuit (24). A control circuit (34) operable in a switched mode supplies a control signal (Is) to the diode modulator (12) for modifying the deflection current (Ih) to correct for side pincushion distortion. A transformer (TR1) has a first winding (W1) coupled to the diode modulator (12) and to the control circuit (34) for recovering energy from the diode modulator (12). The transformer (TR1) has a second winding (W2) for receiving the recovered energy from the first winding (W1). A diode clamp (30) is coupled to the second winding (W2) and to a load (RL) driven by a voltage source at a first voltage level, for transferring the recovered energy between the second winding (W2) and the load (RL). The energy is transferred between the first winding (W1) and the second winding (W2) at a second voltage level across the first winding (W1) determined by the first voltage level and the turns ratio of the transformer (TR1). The second voltage level defines an effective voltage clamping level and is related to the operating range of the diode modulator (12). The second voltage level can be adjusted to levels different from the first voltage level by changing the turns ratio of the transformer (TR1).
