Patent DE-3615610-A1 (DE)
Title: Circuit arrangement for rapid charging of batteries for battery-operated handlamps or pocket lamps (torches)
Inventor: WITTE WALDEMAR
IPC: H02J7/35
Filed: 1986-05-09
Abstract: The invention relates to a circuit arrangement for rapid charging of rechargeable batteries from the mains, having a bias resistor (1, 2) and a bridge rectifier (4) for emitting a virtually constant current to the battery which is to be charged. The current which is emitted from the bridge rectifier is a multiple of the rated charging current. A non-linear, voltage-dependent circuit (7) which is connected in parallel with the battery (6) takes over a larger and larger proportion of the charging current as the voltage on the battery increases, so that, when the maximum charge voltage is reached, the current flowing into the battery is then in the order of magnitude of the continuous charging current. The connecting terminals of a solar generator SG, on the one hand, and the connecting terminals (via which a connection can be produced to an external battery) of a jack plug 11, in addition, are connected to the points X and Y of the bridge rectifier 4. <IMAGE>

Title: Hair curler
Inventor: MERGES HEINZ
IPC: A45D6/08
Filed: 1986-05-15
Abstract: The hair curler (20) is distinguished by the fact that the securing elements have flexible bands (26) with an adhesive covering (26a), which bands can be placed against the outer circumference of the sleeve (21) parallel to the longitudinal axis thereof and can be secured in this position, and that axially directed legs (23) distributed around the circumference are arranged at one end of the sleeve (21). Such a hair curler is held standing on the head without any sharp edges of the sleeve (21) pressing against the parts of the curled strands of hair (27) near to the head. Since the legs (23) raise the sleeve (21) in relation to the scalp, the hair roots are virtually completely free of the hair curler (20) and the hair is neither creased nor compressed so that it is exposed solely to the action of the permanent wave preparation and is not damaged by additional mechanical influences. <IMAGE>

Patent DE-3624195-A1 (DE)
Inventor: WILLIE JOACHIM
IPC: G08B13/18
Filed: 1986-07-17
Abstract: A method of analysis for recognising objects remaining within the detection area of a passive infrared movement alarm and an arrangement for implementing the method are described. In accordance with the invention, the non-uniformity of the measurement background, which depends on physical factors such as absorption, reflection, specific thermal conductivity or varying influence of foreign radiation, is used for the analysis. With a variation in the background radiation field occurring below a lowest specified signal frequency, a background field correction is carried out which adjusts the particular reference value to match the change in the measurement background field. To make the correction, the difference between the current output signal of the radiation detector and an appropriately delayed output signal is taken via a signal amplitude-dependent time- varying reference-level correction circuit to a comparator which controls a timing element and a memory device. <IMAGE>
Patent DE-3625913-A1 (DE)
Title: Method for reducing switching losses in current-injecting frequency converters
Inventor: MEYL KONSTANTIN DR ING
IPC: H02M7/5387
Filed: 1986-07-31
Abstract: The current injection of the present pulse converter having a voltage intermediate circuit is implemented by measuring and regulating each individual phase current via 3-point regulators which have hysteresis. Since the switching losses which occur in the power switches (power circuit breakers) during pulsed operation are proportional to the switching frequency, the invention is therefore based on the object of minimising the switching frequency relating to the driving of the power switches, while maintaining the quality of the phase currents governed by the hysteresis band. In particular, the alternating switching which additionally loads the power semiconductors as a result of ringing currents is to be avoided as far as possible. According to the invention, this is achieved by means of range splitting (BAS) and range gating (masking, blanking) (BAT), according to which alternating switching operation is permitted between in each case one upper and one lower switch for only very small currents and, in addition, as a function of the rotation direction, only until the zero crossing of the nominal value. <IMAGE>

Title: Process for disposing of residues from steel works dust precipitators
Inventor: HORNICH HERIFRIED
IPC: B09B3/00
Filed: 1986-11-03
Abstract: Process for the environmentally sound disposal of water-soluble residues and waste, which pose a risk to the environment, in particular those from dust precipitators in steel works. In order to eliminate the risk of leaching of the substances contained in the residues under landfill conditions, the residues of steelworks dust precipitators and other hazardous waste are introduced into a molten slag present in an arc furnace or running out of the latter during tapping and are allowed to cool together with this slag. This causes vitrification of the residues, which thereby become virtually insoluble under usual landfill conditions and no longer present a risk to the environment.
