Title: Decontaminating hospital waste water contg. radionuclides e.g. iodine - by introducing air bubbles and setting alkaline pH
IPC: G21F9/20
Filed: 1976-10-26
Abstract: The waste is decontaminated by a cascade process comprising introduction of air, in finely divided form, into the cross-current of waste water in vessels. Basic cpds. are added to the waste water while it flows through the aerate vessels, so as to set its H+ ion concn. to values which prevent the escape of radioactive I2 with the used air. Pref. H+ ion concn. is pH >=7 (>=10). The used air from vessels need not be filtered and costs and maintenance are reduced.

Title: Electronic speed control for vehicle - has impulse generator delivering signals to counter with flip=flop reset forming independent control
Inventor: COLLONIA HARALD
IPC: G05D13/62
Filed: 1976-10-27
Abstract: The vehicle speed is converted into signal pulses by an impulse generator to feed a counter. When the required speed is reached, the count is stored permanently by comparing the output of the counter, through a resistor array with the output of the signal generator. The counter is controlled by a flip-flop which automatically resets the counter when the ignition is switched off. The control operates independently to variations in the resistors and is unaffected by capacitance drain etc. in the storage circuit.

Title: Long-acting pyrethroid insecticide compositions - contg. a vaporisation-modifying agent e.g. butyl stearate
Inventor: BERNABE GIUSEPPINA
IPC: A01N/
Filed: 1977-08-29
Abstract: New compositions for the controlled and prolonged volatilisation of a pyrethroid insecticide contain a mixture of at least one pyrethroid insecticide and at least one volatilisation modifying agent. Addition of volatilisation-modifying agents lowers vapour pressure of the pyrethroid preventing premature decomposition, so that evaporation from electrically heated volatilisation devices can be extended for e.g. 8 hrs., thus ensuring continuous insecticidal effect. Typical pyrethroid insecticides include 3-allyl-2-methyl-cyclopent-2-en-4-on-1-yl dl-cis/trans-chrysanthemate and 5-(2-propargyl)-furfuryl dl-cis/trans-chrysanthemate. Typical volatilisation-modifying agents include butyl stearate, didecyl adipate, ethylene glycol benzoate and tricresyl phosphate.

Abstract: The receiver is intended for motor vehicle application in the USW band. It contains at least two receiver antennae (1, 2) in mutual spacing of at least one quarter of the mean operation wavelength. One antenna is connected to a receiver (4). An automatic change-over switch (6) switches over to another antenna, when the signal level of the first antenna (1) is below a given value. Preferably the change-over switch provides subsequent switching of the two antennae to the receiver input, until one provides reception above the given value. The change-over switch may be controlled by a logic circuit (5), dependent on the receiver signal whose amplitude responds to the high frequency receiver input signal.

Title: Automatic focussing system for camera - uses mirror rangefinder with photoelectric cell in compensating network including monostable multivibrator
Inventor: ISONO TADAO
IPC: G02B7/30
Filed: 1977-11-30
Abstract: The automatic focussing system, for a camera, measures the angle of dispersion of light reflected from a subject and adjusts the focussing distance accordingly. Light reflected from the subject (OP1, OP2) is directed by two mirrors (16, 17) onto a reflecting prism (13) and into a photoelectric cell (12). One mirror (16) is fixed and the other (17) pivots. An extension from the pivoting mirror (17) adjusts the camera focussing mechanism. The rangefinder measures pulses light emitted by its own make and break spring mechanism control (21) and looks for the highest intensity reflection at the photoelectric cell (12) by a moving mirror (17). A compensating network with a photocell (25) and monostable multivibrator (28) can be added to ensure the measured light is that which was transmitted.

Title: Sports shoe screwed stud - has aluminium alloy head, with plastics or hard rubber base
IPC: A43C15/16
Filed: 1977-12-15
Abstract: The stud for sports shoes, especially a screwed on stud, is made of plastic or hard rubber and metal, with the tread surface of the stud being of metal. The entire head (10) of the stud, which is subject to wear, is made of an aluminium alloy, and only the base (13) of the stud coming into contact with the underneath sole is made of hard rubber or plastic. The screw (12) for fixing the stud on is also of aluminium alloy, and is integral with the head part (10). That part of the stud made of metal (10, 11, 12) positioned between the head (10) and the screw (12) has a milled part (11) with a smaller dia. than the head (10). Only that part of the milled part (11) is surrounded by a wider edge part (14) of plastic or hard rubber (13). Radial ridges (16) round the periphery make for a better grip.

Title: Rendering safe the waste from polishing barium-glass - by treating with aq. suspension of calcium sulphate to precipitate barium ions as sulphate
Inventor: KISCHIO WERNER DIPL CHEM DR
IPC: H01R12/16
Filed: 1978-05-16
Abstract: Ba ions in waste materials, esp. grits from surface-working Ba-contg. glass, are bonded by treating the waste with an aq. suspension of a water-insoluble sulphate cpd. The insoluble sulphates bond the released Ba ions as BaSO4. The process allows the deposition of toxic Ba-contg. waste on waste tips. The waste is pref. treated with >=1 kg anhydrous CaSO4/kg Ba ions in waste. Anhydrous CaSO4 also acts as a lubricant and filtration aid and increases water-hardness, which is advantageous when using the water for glass polishing.
