Title: Weft injector for air jet loom - has main and sec. air flows into mixing tube with specified divergence for constant flow velocity
IPC: D03D47/30
Filed: 1980-11-17
Abstract: The arrangement is intended for injecting a weft thread into the warp gap of a weaving loom by means of a sub-sonic (supersonic in an alternative arrangement) flow of pressurised transport gas. The injector comprises a chamber (5) connected to the transport air supply (16) and to a first duct (8,7), a second duct (2) through which the thread passes together with a secondary air flow, and a third duct (10) in which the two air flows combine to pass the thread to the nozzle end. The ratio of cross-sectional flow area of the duct (10) to the mass flow rate increases in the flow direction such that at any point along the length of the duct (10) the redn. in air density due to friction losses is at least largely compensated by the increased cross-section. Used as pneumatic weft thread injector for air jet weaving loom.

Patent NL-8602303-A (NL)
IPC: G11B7/013
Filed: 1986-09-12
Abstract: Method of pulse-mode driving of a semi-conductor laser, driving device for a semi-conductor laser and laser-writing apparatus provided with such a driving device. A semi-conductor laser (60) is driven by first driving the laser in the LED region with a pedestal current pulse from a first current source (41) and by superposing thereon an information current pulse from a second current source (51) after current stabilization. Due to this two-stage drive switching transients can be reduced so that shorter pulses are possible and unnecessary power dissipation between the information pulses is avoided which contributes to the lifetime of the semi-conductor laser.

Title: A resonant power converter for energising a coil
Inventor: FERREIRA JAN ABRAHAM
IPC: H02M/
Filed: 1999-05-04
Abstract: A pulse generator is provided for energising a coil with period bipolar current pulses for the purposes of airborne prospecting. The pulses have a generally square waveform, and the pulse generator includes a resonant DC to AC converter circuit including a DC input and an output coupled to the coil. A control circuit is provided for controlling the switching of the converter, and a resonant capacitor is connected in parallel across the DC input. A decoupling diode is provided for decoupling the resonant capacitor from the DC input when the voltage across the resonant capacitor exceeds that of the DC input. The converter includes first and second resonant charging sub-circuits, first and second resonant discharging sub-circuits, first and second freewheeling sub-circuits and first and second exponential charging sub-circuits. The control circuit is arranged to control the amplitude and frequency content of the square waveform by switching the convertor circuit to operate between the above sub-circuit types in at least one controlled switching cycle during unipolar current pulse intervals. The circuit further includes a clamping circuit arranged to supply a substantially constant DC voltage to the coil which is higher than that of the DC input.
Patent PT-68986-A (PT)
Title: Modular unit for the construction of a floating deck for liquid storage tanks
IPC: B65D88/00
Filed: 1978-12-27
Abstract: A modular structure for making a floating apron to control the evapn. of a liq. in a storage tank comprises a core made of foam plastic e.g. polyurethane and an envelope. The envelope encloses the core and forms a barrier which prevents the core absorbing liq. or vapour. It consists of a layer of flexible metal which is a good conductor of electricity, entirely covered with an outer layer of plastic material to prevent corrosion of the metal by the stored material. This metallic part can be fitted with an inner layer of plastic material to increase adherence between the core and the metal. It is preferable however to treat this inner layer e.g. by flame treatment to ensure liaison between the core and the coating. Problems associated with absorption of liq. by the polyurethane, corrosion of the metal layer, sinking of the apron and diminishing of rigidity are avoided. The floating apron made from the modules according to the invention cannot be attacked by the contents of the tank, cannot be submerged and is impermeable to liquids or vapours, while being economical and simple to install.

Abstract: PCT No. PCT/SE84/00368 Sec. 371 Date Jun. 19, 1985 Sec. 102(e) Date Jun. 19, 1985 PCT Filed Oct. 31, 1984 PCT Pub. No. WO85/02509 PCT Pub. Date Jun. 6, 1985.Digital signals which are sent each with their own frequency are corrected for frequency-dependent attenuation of the transmitting medium in a filter (5) so as to maintain a desired relationship between the amplitudes of the signals after the filter. Difference circuits (6) which have output signals (US1, US2, US3) control the filter means, obtain signals (Uf0) on their first inputs from a common voltage supply circuit (9) and signals (Uf1, Uf2, Uf3) on their second inputs from a voltage supply circuit (10) for each of the output signals. A decoder (18) sends a control signal (S0, S1, S2, S3) associated with the respective digital signal. The control signals reset switches (17) whereby the voltage supply circuits (9, 10) obtain signals from an amplitude detector (13) corresponding to the respective frequency in the transmitted signal. Each of the output signals (US1, US2, US3) fed to the filter (5) by the difference circuits (6 ) thus corresponds to a digital signal.
