Title: Mfr. of concrete moulding with patterned surface - by placing fabric sheet in mould before pouring concrete into mould
Inventor: KOTHE HELMUT
IPC: E04G9/10
Filed: 1977-09-29
Abstract: Concrete mouldings are made with a pattern on >=1 surface by placing a sheet of fabric in the mould or on the shuttering before pouring the concrete into the mould. The fabric remains on the concrete after the mould or shuttering has been removed. A fabric or flat material with an open porous structure is pref. used, and may be coated with an adhesive or water prior to insertion in the mould. The concrete penetrates into the porous fabric or mesh and hardens in the pores or cavities of the fabric. The fabric may also be a patterned plastic foil.

Title: Tool for machining wall of plastics tube - uses hydraulic cylinder to keep tool tips at correct spacing on inner and outer side of tube wall
Inventor: NOWIK JOSEF ING GRAD
IPC: B23Q1/68
Filed: 1977-10-21
Abstract: The plastics tube is machined with a tool which removes material simultaneously from the outside dia. and the bore. The tool holder (1) consists of two parallel arms (5) connected by a bridge piece at one end and fitted with cutting tips (6) at the other end of each arm. To maintain accurate control of the wall thickness of the finished machined tubes, the distance between the tool tips (6) is maintained by a hydraulic cylinder (8). This presses the arms outwards against the stops formed by the bolts (9).

Title: Dentifrice with improved cleansing and polishing action - contg. abrasive agent together with zinc cpd. to reduce abrasion of dental enamel
Inventor: CORDON MARTIN
IPC: A61K8/26
Filed: 1977-10-26
Abstract: Dentifrice with improved cleansing and polishing properties contains >=1 abrasive agent with a particle dia. of 1-15 mu, and a non-toxic Zn cpd. in an amt. of >=0.0065 wt. %. The abrasive agent is either (a) Ca pyrophosphate in an amt. of >=7.5 wt. % or (b) a hard abrasive agent selected from calcined Al2O3, Zr, silicate, crystalline SiO2, Ca silicate, KAlSi3O8 sand, SiC, pumice, ilmenite, CeO2, Fe2O3, ZrO2, SnO2 and topaz in an amt. to give the dentrifice a radioactively determined enamel abrasion (REA) value of >=400. When the abrasive is Ca pyrophosphate, the Zn cpd. is ZnO and is pre-mixed with the Ca pyrophosphate before incorporating into the dentifrice. When the abrasive is Zr silicate or crystalline SiO2, the Zn cpd. is ZnCl2 and/or ZnO. Incorporation of a Zn cpd. reduces the effect of the abrasive agent on the dental enamel without adversely affecting its effectiveness in removing resistant flecks and food residues from the tooth surface, so that a good polishing and cleansing effect is obtd. without the risk of damage to the enamel.

Title: Ground water conducting layer flow capacity assessment - involves metering excited fluid level oscillation for mathematical or graphic analysis
Inventor: KRAUSS GEB SEIDENBACH IRENE
IPC: E02D1/02
Filed: 1978-01-28
Abstract: The process for determining the transmissive capacity of an earth stratum through which fluid moves, is esp. applicable where ground water is conducted.

Title: Swaging machine for curved pipes - has hydraulic motor driven rollers mounted on hydraulically balanced platform raised by cylinder underneath
Inventor: BUCHMUELLER HEINZ
IPC: B21D17/04
Filed: 1978-06-10
Abstract: The machine which can swage the end of a curved pipe has a frame (1) with guides (13) for a platform (11) which can move vertically up and down.

Title: Voltage to frequency conversion circuit - stores result as digital number and obtains offset value by additional conversion process
Inventor: SCHULZ ALFRED DIPL ING
IPC: H03M1/00
Filed: 1978-06-22
Abstract: The convertor is used esp. for voltage into frequency conversion with subsequent storage as a digital number. The keying ratio of a pulse generator obtained by integration is compared with the unknown analogue value. The convertor converts many input voltages into series nor parallel digital numbers which are at least temporarily stored. In order to correct offset error an additional A/D conversion is carried out without an input voltage, but with such connection of the system inputs, that the offset value is obtained. This value is at least temporarily stored and used during following measurement processes.

Title: Ultrasonic technique for metrology - using peak value sensors responding to test piece end surfaces to operate flip=flop, gate element and counter
Inventor: MOELLER PETER DIPL ING DR
IPC: G01B17/02
Filed: 1978-12-08
Abstract: Impulse reflection techniques are used to determine the thickness and other dimensions of a test piece using ultrasonic waves. A scanning method is used which produces a sequence of wave responses which have peak values at the ends of the test piece. The appts. used includes two peak value memory units with a centrally situated delay unit. Output voltages are transferred to two comparators along with a common signal through the delay unit. Comparator outputs are used to manipulate a flip-flop, a gate element and a counter which forms an output signal proportional to displacement. For test pieces with rotational symmetry, a pair of sensors may be used at opposite ends of a diameter. To smooth out spurious readings a technique may be used where the display responds to a sum of 10 consecutive pulses.

Title: Microwave region frequency measurement - has quartz crystal accuracy by broad band mixing into automatic digital microwave counter
Inventor: GROLL HORST PROF DR ING
IPC: G01R23/02
Filed: 1979-02-13
Abstract: An arrangement enabling the frequency range of an automatic digital microwave frequency counter to be expanded is a routinely useable combination of an electronic circuit and microwave components. It gives accuracy equivalent to square crystal measurement in the range 26 to 40 GHz but may also be used for higher frequencies. A signal lying outside the counter frequency band is converted into an intermediate frequency using a free-running oscillator whose frequency is measured by the counter, a frequency multiplier, and a broad band mixer. The intermediate and oscillator signals are alternately switched to the counter via an electromechanical or diode switch for automatic derivation of the unknown signal frequency. The switch is controlled by the counter print pulse. The multiplied oscillator frequency lies on the side of the signal band corresp. to highest mixer losses.

Title: Sulphonation of organic cpds. using sulphur tri:oxide - with membranes of tetra:fluoroethylene and per:fluorovinyl:ether mixed polymers
Inventor: VAUGHAN RONALD J
IPC: C07C67/00
Filed: 1979-05-16
Abstract: The sulphonating agent and the organic compound to be sulphonated are maintained basically separate from each other, by a membrane which is near enough chemically inert relatively to the partners in the reaction, in the sulphonation of organic compounds. Pref. the membrane is of a perhalogen-carbon polymer which has terminal carbon acid-, phosphonic acid or sulphonic acid radicals or mixtures of these. Used for the production of cationic exchange materials, anionic wetting agents (surfactants), as well as additives to lubricating oil, such as sodium dodecylbenzolsulphonic acid, a main constituent of detergents. Certain types of membranes can be used in non-aqueous environments under conditions which permit a selective contact between partners in a reaction, so that reactions which were previously difficult to control can be carried out easily. The invention overcomes the problems of known processes and yields a sulphonated product which is free from undesired byproducts.
