Title: Thixotropic bleaching powder dispersion prodn. for decontamination of chemical warfare agents - involves dispersing bleaching powder in colloidal alumina and silica, and copolymer resin in water
Inventor: LETTKO HERBERT
IPC: A62D3/38
Filed: 1991-05-04
Abstract: Process for producing a thixotropic bleaching powder dispersion (I) for decontamination of chemical warfare agents (II), e.g. S-LOST, N-LOST, Lewisite, organic phosphate esters such as Tabun, Soman, Sarin, VR and VX, esp. chemically thickened (II). The novel features are that (a) 20 kg bleaching powder (III) (ca. 36%) are added to 80 kg water in a high power disperser; (b) after dispersion (ca. 1-2 min), 1-2 kg colloidal SiO2 (IVA) contg. 16% colloidal Al203 (IVB) are added; and (c) after dispersion for 1-2 min longer, ca. 2% of a 50% copolymer resin dispersion (V) are added. Pref. addn. of a 3-10% soln. of morpholine in ethylene glycol dialkyl ether makes (I) resistant to cold down to -10 deg. C and inhibits oxidn. of unalloyed steel. USE/ADVANTAGE - It is claimed that (a) (IV) acts as thixotropic agent; (b) (V) acts as crystallisation inhibitor; (c) (IV) causes thixotropic thickening which is stable for at least 48 hrs. and ensures that the original sprayable thixotropic state returns after brief stirring; (d) even moist lumps of (III) can be used; and (e) at elast 95% electrical energy is saved cf. with the dry milling process. The viscosity is increased without using chlorohydrocarbons and (I) is readily degradable.

Patent DE-4121333-A1 (DE)
Inventor: PETERMANN CHRISTOPH
IPC: H01Q5/15
Filed: 1991-06-25
Abstract: The invention relates to a foil antenna for radio telephones, especially cordless telephones. Instead of the previously normal rod antenna, whose length corresponds to a quarter of the wavelength of the frequency which is to be transmitted or received, a foil antenna is proposed as the antenna. The foil antenna according to the invention has radiating elements which are connected to one another by means of inductors. In addition, the matching circuit is accommodated on the foil. The inductors which are arranged between the radiating elements are essentially constructed as straight line pieces. The antenna according to the invention can be produced easily in production-engineering terms, can be completely integrated into the housing of the cordless telephone, and has a relatively high efficiency with dimensions which are considerably less than the length of the previously normal rod antenna. <IMAGE>

Patent DE-4132072-A1 (DE)
Inventor: MAHMUD SHABAZ
IPC: G01R31/3185
Filed: 1991-09-26
Abstract: The invention relates to an integrated semiconductor circuit which comprises a number of functional blocks which can be tested individually, and which contains a selection arrangement with which the individual functional blocks are selected for the test. Due to the move towards increasingly higher integration densities in integrated circuits, it is becoming increasingly difficult to test functional capacity. For this reason, subsequent testability must be borne in mind even during the development of an integrated circuit. A read-only memory area (ROM area) is therefore provided in an integrated semiconductor circuit in which a bit pattern is in each case stored under an address which serves to activate a selection circuit or directly to select the functional block to be tested. A counter is furthermore provided whose counter reading can be incremented by an external counting signal and whose counter reading indicates an address for the read-only memory area which contains a bit pattern for the selection of a functional block. <IMAGE>

Inventor: HUESTER BERNHARD
IPC: B67D7/06
Filed: 1991-11-13
Abstract: In order to regulate the speed of rotation of the driving motor (18) of a gas feeding pump (12) that ensures gas return during a fuelling process, in particular when the fuel filling flow increases or decreases at the beginning or end of the fuelling process, so that this speed of rotation is proportional to the amount of returned gas, according to a predetermined calibrating curve, and so that errors affecting the speed of rotation of the motor may be immediately detected and electronically compensated, the real values of the volume of fuel fed into the tank are converted by a pulse generator (5) and supplied as an input value to a regulating unit (16) in the form of a processor, along with the fedback tachometric voltage of the electric motor (18) linked to the gas feeding pump (12). The regulating unit (16) constantly compares said input values and supplies at its output a controlled variable for the electric motor (18) that is proportional to the difference between the volume of fuel filled into the tank and the amount of gas returned. The computer (6) connected to the pulse generator (5) and regulating unit (16) converts the measurement data from the liquid measurement motor (4) and displays them on a monitor for service station clients. The output of the regulating unit (16) is directly connected to the pump motor (18).

Title: Vehicle tyre with long service life - has two similar halves bonded together, each having tread, so that when one tread is worn out tyre is reversed and inner tread faces outwards
Inventor: BRANNAN DAVID
IPC: B60C11/00
Filed: 1992-03-25
Abstract: A tyre, and particularly one for a powered vehicle, has an out tread and inner face, a sidewall with carcass, and a radially internal bead. The tyre is made up of two pain parts which can be bonded together beforehand; both parts have one smooth and one profiled face when they are laid flat; the parts are pref. joined together as mirror images; the single tyre carcass lies between the two smooth faces. The example shown is made up of two halves which are virtually equal, so that both the outer and inner faces (1) can be used as treads. Thus each part has a tread portion along its centre. The two parts are joined together, with the beads at the ends. Their smooth sides face each other, and they can be produced singly or already joined together. Another option is to have one part with a summer tread and the other a winter counterpart. ADVANTAGE - The tyre has a long service life. Its cost is resonable. It meets safety requirements. When the tread has worn out smooth the complete tyre can be turned inside out and used again until its second tread has gone.

Patent DE-4218435-A1 (DE)
Inventor: TUMALSKI TADEUSZ
IPC: F16B15/04
Filed: 1992-06-04
Abstract: In order to fasten structural parts on a porous underlying surface such as, for example, gas concrete, a nail for gas concrete is formed from a half-round metal rod which is grooved transversely to the longitudinal axis. The points, projecting away from each other, of the nail are pushed through the splitting disc (7) and the nail is driven into the material. The transverse bar (6) of the splitting disc acts on the two shank halves of the nail with a lateral force which spreads out the nail in the form of a claw, independently of the effect of the underlying surface. In addition, the transverse grooves of the nail improve the load-bearing capacity of the connection in the gas concrete. <IMAGE>
