Title: Washing or bleaching compsns. for textiles - contg. calcium binding agent and additives delaying pptn. of calcium cpds.
Inventor: SCHMADEL EDMUND DIPL CHEM DR
IPC: C11D3/36
Filed: 1975-09-03
Abstract: Textiles are washed or bleached in an aq. bath contg. a substance capable of binding the agents causing hardness of water (>=50 mg CaO/g.), in partic. a finely dispersed, water-insol. opt. hydrated cpd. of formula (Cat2/nO)x. Me2O3. (SiO2)y (in which Cat is a cation that can be exchanged for Ca2+; n is the valence of this cation; x = 0.7-1.5; Me is B or Al; y = 0.8-6); and also builder(s) andopt. surfactant(s). In this addn., the mixt. contains a combination of builders contg. water-sol. salts having cations that do not hinder the formation of calcium complexes, in partic. salts of (A) a phosphonic acid which considerably delay the pptn. of calcium cpds., or a calcium complex-binding phosphate; and (B) a phosphorous-free polyanionic cpd. considerably delaying the pptn. of calcium cpds.; with the proviso that their sodium salts (0.5 g/1.), when added to a soln. of Na2SO4 (2.5 g/1.), in water having a calcium hardness of 22.4 degrees d (224 mg CaO/1.) and a bicarbonate hardness of 14 degrees d (140 mg Ca(HCO3)2/1.) with a pH adjusted to 9, prevent the formation of a visible ppte. after boiling under reflux for 30 mins. The weight ratio (A):(B) is 1:10 to 10:1, pref. 1:3 to 3:1. The use of the above calcium-binding cpd. and the above combination of builders permits the elimination or redn. of the phosphate content in the washing or bleaching bath.

Title: Small switchboard signalling system - has signalling oscillator for loudspeaker modulated by second incoming call
Inventor: LECHNER JOERG
IPC: H04M19/04
Filed: 1975-09-24
Abstract: A calling method for a telephone station to which several lines can be connected, uses a common calling element for all lines. When a call arrives over one of the lines (AL1-Aln) an oscillator (0) is made to deliver a calling voltage to the calling element (L) which may be a loud speaker. This voltage is modulated by the incoming calling a.c. voltage. When a second call arrives over a second line, while the first call is still going, the oscillator voltage is modulated by a voltage whose frequency is twice that of the incoming calling voltage.

Title: Barstock supply system for automatic machine tools - has cable operated push rod and continuous supply of hydraulic oil for smooth running and noise damping
Inventor: MARCHAND ERIC
IPC: B23B13/00
Filed: 1976-05-13
Abstract: The feed-in arrangement consists of a split tube (7) in which a push rod (8) is mounted. A vane (9) is mounted on the push rod, which protrudes through the slit in the tube. A cable (11) which is attached to this vane moves the push rod (18) against the rod material (18) and pushes it into the machine tool. To reduce the noise coming from the arrangement it is surrounded by a housing (6). Hydraulic fluid is fed into the housing so that the push rod runs in oil and further reduces noise. The oil is collected in a sump (20) at the front of the housing from which it is returned to the oil pump.

Title: Slow release granular fertiliser prodn. - by granulating a mixt. contg. alkaline earth (hydr)oxide and treating with carbon dioxide
Inventor: KEIENBURG HELMUT
IPC: C05D3/02
Filed: 1976-06-16
Abstract: Process for making long-lasting fertilisers comprises using lime, calcined dolomite and magnesite, cpds. of N,P,K useful as fertilisers and other usual components, by first granulating with addn. of water mixts. contg. >=30 wt. % alkaline earth oxides and/or hydroxides (calculated on oxides plus fertiliser ingredients). The granules are then treated with CO2 at 100-250 degrees C. Pref. the granules are granulated a second time, before CO2 treatment, with 5-20 wt. % alkaline earth oxides and/or hydroxides to give them an oxide coating. Treatment with CO2 causes partial recarbonisation of the surface oxides so that the speed at which the soluble fertiliser components are released is much reduced. Components which are normally incompatible can now be used together.

Title: Parameter changing for elastomechanical oscillating system - has feedback circuit for elastic damping of mass forces
Inventor: BREITBACH ELMAR DR ING
IPC: G01M7/02
Filed: 1976-06-28
Abstract: The oscillating system parameters are rigidity, damping and/or mass. Distances travelled, velocities and/or accelerations in the oscillating system are measured. The signals are generated in the form of a voltage from which interferences have been removed, and applied as control signal to a power amplifier which generates a current proportional to the control signal. This current is applied through an oscillation exciter in the form of a force corresp. to elastic, damping or mass force to the oscillating system, thus closing a feed-back circuit so produced. The interferences are removed by a filter which is provided with a controllable generator (6). The filter (3) is phase and amplitude coherent.

Title: Cooling system for power transmission tubes - has inner and outer cooling cylinders with spacers formed by U=shaped wires whose free shank ends pass through inner cylinder bores
Inventor: BADENHOOP RAINER
IPC: H01J7/28
Filed: 1976-09-23
Abstract: The cooled transmitter tube has an outer anode which can be inserted in a water cooling pot, consisting of an outer and an inner cooling pot cylinder. The spacing between the anode and the inner cylinder, and the inner and outer cylinders, is determined by distance pieces secured in the inner cylinder (2). The spacing is determined by several U-shaped wires (4) secured to the inner cylinder, whose inner parts extend in axial direction. The free shanks (5) of the wires are put through bores (7) in the inner cylinder. Preferably the spacing is determined by the dia. of the free shanks which are bent or crimped. Alternately the spacing is determined on one side by the dia. and on the other side by the length of the free shanks, which may be several times shorter than the middle wire part.
Patent DE-2645058-A1 (DE)
Title: Antenna system with several individual units - consists of set of antennae between which further units for smaller frequency range are inserted
Inventor: KURZ GEORG
IPC: H01Q5/42
Filed: 1976-10-06
Abstract: Individual antennas are mounted in a plane and can be connected as required. In order to widen the antenna frequency range without increasing secondary lobes of its directional characteristic and without unwanted couplings between adjacent individual antennas, the packing density of antennas is increased by insertion between each two wide band antennas for the full antenna system frequency range, of a similar antenna for a part of the total frequency range. Alternatively two or more individual antennas of the same or similar type for the same or for different parts of the total frequency range may be inserted.

Title: Purifying waste waters contg. organic materials - e.g. yeast and protein, by adding alumina and or silica in addn. to polyelectrolyte
IPC: C02F1/52
Filed: 1976-12-07
Abstract: Purificn. of waters contaminated with organic, esp. protein and yeast-contg. materials, is effected by adding an aq. suspension of finely-divided Al2O3 and/or SiO2, in addn. to a polyelectrolyte, esp. polyacrylamide as flocculant. Process is used for purifying grape-pressing-, brewing-, dairy- and fruit-processing waste waters. The dehydrated solid concentrates obtd. can be used as soil-improvers for dumped. Flocculation is accelerated, e.g., the addn. of Al2O3 and/or SiO2 to polyacrylamide can increase BOD5 reduction from 20-25% to 80-90%. Large flakes are accumulated, which settle quickly. Filtration is not required.

Title: Food smoking chamber system - with three phases of circulating with and without smoke generator and venting
Inventor: REICH WOLFGANG
IPC: A23B4/052
Filed: 1977-06-04
Abstract: System for the operation of a food smoking chamber for hot and cold smoking processes uses three phases. In the first, a smoke generator feeds smoke into the chamber in which the air/smoke mixture is circulated in a closed circuit. On reaching the max. air humidity, the smoke generator is cut off and circulation continues until the food has absorbed nearly all the smoke. The third phase is a venting period which starts when no environmental pollution need be feared. This system can be applied to a conventional smoking chamber with very little additional appts. It demands no extra consumption, yet satisfies all statutory regulations concerning antipollution limits of emission.
