Title: Apparatus for recharging batteries by means of pulsating current
IPC: H02J7/00
Filed: 1980-11-17
Abstract: An apparatus for recharging dry batteries or accumulator batteries by means of pulses of alternating current or any other type of intermittent pulses and for a slight discharging of the batteries or accumulators during the periods appearing between the recharging pulses and comprising a mains connection circuit (A) and a recharging circuit (B) connected thereto having terminals for one or more batteries to be charged and a rectifying means (8) supplying a direct current to a controllable guide means (19). The apparatus comprises a control unit (C) which is connected to the guide means (9) and which defines the moment (75) of the alternating current pulse or the other intermittent pulse when the recharging circuit (B) is activated and a recharging voltage is supplied to the battery (13). The guiding means (9) may be a tyristor which is made conducting by the control circuit (C) at a predetermined moment (75). The control circuit (C) comprises means for optional continuous or stepwise controlling of the trigging moment (75) for the recharging pulse during the extent of the recharging and thereby for controlling the length of the recharging periods and the intermediate discharging periods. The apparatus comprises means for changing the level and the duration of the recharging voltage during the recharging operation especially after a given recharging period by increasing the recharging voltage and concurrently therewith move the trigging point (75) for the recharging pulse so that the duration of the recharging period is reduced and the duration of the discharging period is increased.

Title: Carbon gasification method
IPC: C21B11/00
Filed: 1982-05-19
Abstract: A method of gasifying carbon (C) in the form of coal, hydrocarbons and/or hydrocarbon compounds, comprising the steps of into a reactor vessel holding a molten iron bath to inject carbon, oxygen and iron oxides beneath the surface of the molten iron bath, where the iron oxides constitute a coolant and where carbon is injected in a stoichiometric excess relative to oxygen included in the bath in the form of oxides, and where the molten iron bath has such a carbon content that it solves-in carbon. According to the invention, the reactor vessel is caused to have an inner total pressure of 2 to 50 bar, preferably 4 to 10 bar. Hereby the gas production and the production of pig iron increase. Furthermore, the dust formation and the lining wear are reduced substantially.

Title: Intruder detector and method
Inventor: PENET TRISTAN
IPC: G08B13/183
Filed: 1982-10-12
Abstract: A method of detecting the presence or the passage of an intruder in a region under surveillance comprises: transmitting an infrared beam from a transmitter; receiving the beam in a receiver such that the region under surveillance is determined by the path followed by the beam between the transmitter and the receiver; and raising an alarm indicative of the presence or passage of an intruder whenever there is a significant change in the characteristics of the beam as received by the receiver. The infrared beam is transmitted in the form of pulses (Figure 1A), each comprising a packet of oscillations (Figure 1C) at a carrier wave frequency (Figure 1B), and the receiver is tuned to be sensitive to infrared radiation whose amplitude varies at said carrier wave frequency. This provides considerable immunity from interference by such natural phenomena as the sun and fog, and can also be made highly tamper-proof. <IMAGE>

Title: Calibration of electronic taximeters
Inventor: ROYDS TOM LONGSTAFF
IPC: G07B13/08
Filed: 1982-11-23
Abstract: An electronic taximeter is programmable to a tariff by a plug-in device. Pulses from a transducer on the transmission are fed to the taximeter to indicate distance travelled. To facilitate re-calibration, the programming socket, which is sealable, can alternatively receive a calibration device. When this is plugged in and a calibration mode keyed, the vehicle is driven over a set distance. The distance pulses are then directed to memory in the taximeter, and stored to serve as the tariff base.
