Patent DE-2530562-A1 (DE)
Title: Benzotriazole metal surface corrosion inhibitor solns. - in organic solvents, for incorporation in lubricants
Inventor: KREUTZER INGO
IPC: C23F11/14
Filed: 1975-07-09
Abstract: The soln. comprises benzotriazole, methyl benzotriazole and/or tetrahydrobenzotriazole dissolved in an amine salt of a carboxylic or phosphoric acid, a trialkyl phosphate ester, an aminealkyl benzyl sulphonate or mixts. of these. The solns. are added to lubricants to prevent corrosion of machine parts eg. hearings esp. by S-contg. oils. Solubility of the benzotriazole or derivs. in oil is increased around 9 times, and the corrosion-inhibiting action increased, so that a smaller amount can be used. In an example 0.3% of a mixt. of 400 g isohexanic acid, 250 g isodecylamine and 350 g benzotriazole is dissolved in paraffinic spindle oil at 22 degrees C.

Title: Automatic tumble dryer with multistage dryness indicator - allowing user to estimate time of end of drying
Inventor: PETERS HANS ECKART
IPC: D06F34/32
Filed: 1975-07-09
Abstract: The dryer comprises programme and control means which allow the drying process to take its course in dependence on the residual moisture content of the clothes. The dryer also includes an indicator which indicates the degree of dryness reached by the clothes during the programme, in stages. The end of the drying programme may occur as soon as the actual degree of dryness of the clothes corresponds to that which has been preselected. The programme selector and indicator may be in the form of a rectangular assembly of panels in which the individual panels can be illuminated. The user can estimate from the panels when the programme will be finished, and can interrupt the programme to remove individual articles of clothing when the load contains different kinds of fabric.

Title: Rotating cylinder engine gas and oil mixture regulator - prepares fuel without addition of air external to cylinders
Inventor: BAENTSCH ERICH
IPC: F01L7/10
Filed: 1975-12-01
Abstract: A rotating cylinder engine has an injector pump which forces the fuel through a heater situated close to the exhaust. The heated fuel then flows to the injector, which is adjusted to 100 atmospheres pressure, before joining the combustion air flow to the cylinder. The fuel and air mixture enters the cylinder through a rotating slide valve to be ignited by a heater spiral (33) which is supplemented by heat from the exhaust channel (17). The injector is adjusted to higher pressure for cold start purposes.

Title: Respirator device with automatic condensed water elimination - has removal pipes to remove condensed water and warm and moisten inspired air
Inventor: LANG VOLKER DR
IPC: A61M16/08
Filed: 1975-12-15
Abstract: A respirator head is used with through-flow systems with automatic condensation elimination. It is esp. for use by new born or small children. It is constructed such that the respirator head and condensed water removal device form a single unit. Automatic expulsion of condensed water occurs via pipes in the base of the device during inspiration. The removal pipes act as continuous leaks and serve to warm and moisten the inspired air. The pipes lie directly below the cover of the respirator head allowing condensed water to collect in the floor of the device and not within the user.
Patent DE-2556692-A1 (DE)
Title: Aqs., alkaline textile cleaning compsn. - contg. borax as buffer and no polluting fillers
Inventor: GOLD HORST
IPC: C11D3/02
Filed: 1975-12-16
Abstract: In this cleaning mixt., the buffering substance comprises mainly or solely of borax. This mixt., when used as a 0.001-0.008 wt.% soln., produces a bath of pH = 7.1-8.8 without the need for any (alkaline) additives. Being an aqs. soln., the detergent requires no polluting fillers (e.g. phosphates) and, having a sp. gr. 4-5 times the corresp. granular products, does not result in large packages. (Spray)-drying and similar process are likewise obviated.

Title: Solvent extraction in multistage contraflow - in revolving drum with deflector blades for propulsion of solvent
Inventor: HEINZ ERNST DIPL ING
IPC: B01D11/02
Filed: 1976-04-24
Abstract: Extn. of soluble substances from solids by contraflow of solvent through the solids is carried out as follows. The solid material is alternately centrifuged and tumbled as it is propelled through the process simultaneously, the solvent (extract soln.) is sepd. from the extract material during the centrifuging stage and the rotational energy thus obtd. by the solvent is converted into press. energy and used to propel the solvent in contraflow to the extracted solids. Only a portion of the extract soln. may be advanced towards the next stage, while the remainder is returned into the same stage. The extracted material may be turned over several times within the same stage. Used for multi-stage, contraflow solvent extn. to obtain max. extn. efficiency. The system obtains a very high extn. rate with comparatively simple and easily constructed plant. Maintenance is reduced to a min.

Title: Tachogenerator for record player speed control - has four stator windings at 45 degree phase intervals to double frequency
Inventor: RICHT OSKAR HUBERT
IPC: G01P3/487
Filed: 1976-07-09
Abstract: The tachogenerator with high-frequency output is particularly suitable for speed regulation of low speed mechanisms, e.g. tape recorders and record players. The generator rotor comprises a ring of magnetised material having alternate north and south poles (1) which is attached to the drive motor rotor. The stator windings are constructed on two separate thin discs (2, 3). Each disc is approx. 0.1 mm thick with a printed, serpentine winding on each side, 90 deg. out of phase with the other (2a-b). The discs are fitted together on the stator of the motor so that their respective windings are offset 45 deg. to each other. This provides an output signal whose frequency is twice that of the usual device, thus providing greater resolution of angular velocity.

Title: Registration error correction device for recording appts. - senses reference line and generates stylus position signal
Inventor: WALLNER FRANZ DR ING
IPC: G01D9/00
Filed: 1977-01-26
Abstract: A control device for the zero position and operating region of the styli of a single- or multi-channel recording appts. such as an oscillograph or direct recording instrument employs a single electrical signal to move the styli transverse to the recording paper and to compensate for registration errors introduced by lack of precision in the transport mechanism of high speed recording systems. The device relies on the sensing of either the edge of the recording strip or a guide line marked on it. the guide line may be an abrupt colour transition, a change of transparency or of electrical or magnetic properties. A signal derived from the device monitoring the edge or guide line serves to correct the instantaneous nominal position of the styli, thereby eliminating errors.

Title: Plug coupler system for HV power appts. - is contained inside enclosing tube to enhance mechanical stiffness
Inventor: LORENZ DIETER DIPL ING
IPC: H02G5/06
Filed: 1977-02-18
Abstract: The conductors to be connected (1, 2) are typically contained in a duct (4) and supported by disc insulators (3). A tubular support (8) is permanently attached to one conductor (1). At its open end (9) the tube has a bore (11) eccentric to the conductor axis (10). The bore contains a bush (12) which also has an eccentric bore (13) whose diameter matches that of the second conductor (2). By relative circumferential movement of the tube (8) and brush (12) the axial misalignment (a) between conductors can be accommodated. The electrical connection is typically made by a laminated tube (7) sliding over spherical terminals (6) attached to the end of each conductor. The tube (8) fitting between the conductors relieves the jointing tube (7) of any mechanical loads due to current flow. It also acts as a screen for the connection. The bush (12) is normally of insulating material, and the tube of metal.

Title: Auto-thermal fuel gasification under pressure - using side stream for low temp. carbonisation and fixed bed heat generation
Inventor: TOELLE ROLF DR
IPC: C10G1/00
Filed: 1977-07-19
Abstract: In the autothermal gasification under pressure of large-sized fuel, e.g. bituminous coal, with steam and air or oxygen in a fixed bed gasifier, the fuel is carbonised at low temp. before the gasifying reaction with a side stream of the process gas. The low temp. gas is extracted and burned at less than the stoichiometric ratio. The gaseous prods. of the combustion are used to generate the heat for the gasifying reaction in the fixed bed. This results in a better control of the combustion process. The overall efficiency of the gasification is improved by a reduction of the steam consumption and of the moisture content in the process gas.
