Title: Brush bedding process for small commutator motors - employing chemical reaction between ammonium salt and carbon to remove excess brush material
Inventor: TEUSCHLER HANS-JOACHIM DR
IPC: H01R39/46
Filed: 1980-08-11
Abstract: The brush bedding process is to reduce the running in time required and hence improve on mass production output. The process is also applicable to sliprings. Bedding is achieved by chemical reaction. The surface of the commutator or brush is treated with an ammonium salt, for example ammonium phosphate or ammonium chloride. When the machine is first run the inevitable arcing at the brushes produces a plasma condition between brush and commutator in which the salts react with the brush material and form the brush to the smooth contour of the commutator. The reaction can take place in air of controlled humidity or in a special atmosphere of nitrogen or hydrogen. The process is such that the salts are finally sublimated and removed after the bedding process. A reduction in running in time from the present typical 30 min. to 1 hour down to 3 to 8 minutes can be achieved.

The elements are axial and/or radial projections whilst the members consist of resilient rings or discs engaged by respective projections. The axial projections of each corresponding pair may be spaced (S) radially and surrounded by a resilient coupling ring (6), the centres of these rings lying on a common pitch circle. The axial projections of each pair may have complementary semi-circular cross sections.

Title: Ionisation manometer triode - with cathode and grid facing slot in cylindrical anode
Inventor: GENTSCH HORST PROF DR
IPC: H01J41/04
Filed: 1980-11-08
Abstract: A Bayard-Alpert ionisation manometer triodiee has a cylindrical anode with a longitudinal slot facing a grid and the cathode. The electrons have to pass through this slot. The grid is insulated separately from the anode; both are kept at the same potential. Square plates at both ends of the anode cylinder have several holes for the passage of an ion trap. The new triode is not sensitive towards electrostatic fields. The thin collector of conventional gauges causes a perihelion path for the ions so that many miss the trap.

Title: Wind resistant solar energy conserving pitched roof panel - has edge headed pins locking into previous row resilient bent pieces
Inventor: GLASER HORST
IPC: E04D13/18
Filed: 1980-11-19
Abstract: The covering panels made of heat-conductive materials are laid like slates on heat-insulating panels, and clamped in ribs on these by resilient bent sections in a steeply sloping roof structure deriving heat from the sun and environment . To prevent lifting off in strong gusts of wind, the covering panels (4) are additionally secured by headed pins (7). These grip a lateral edge of a panel (4-4) being laid, and lock into the resiliently bent part of a panel (4-2) in the row previously laid. The bent section can be appropriately shaped, pref. with an edge section matching panel overlap width. Mechanical rigidity is enhanced.

Title: Process for separating lipophilic constituents from aqueous colloid solutions for preparative purposes and/or for detecting an analyte in the aqueous phase
Inventor: HEUCK CLAUS-CHRISTIAN DR RER N
IPC: G01N25/14
Filed: 1981-05-07
Abstract: A process for removing fat-soluble constituents from aqueous colloidal solutions is described. The process is characterised advantageously in that the physicochemical and biological properties, in particular even of the amphiphilic colloids in the aqueous solution are retained. As a result they are accessible to a qualitative and quantitative biochemical analysis or further work-up. The extraction method is based on the use of mixtures of organic solvents containing a water-insoluble component, which has a surface tension < 25 dyn/cm, and a component having a low water solubility and a surface tension < 20 dyn/cm. The proportion of the water-insoluble component is 50 to 98% by volume of the solvent mixture. Characterisingly, in the liquid-liquid phase extraction from colloidal solutions of biological origin, even in the undiluted state of the aqueous sample - in contrast to extraction methods known hitherto - no intermediate phase is formed in which in particular colloidal analytes having amphiphilic properties are enriched in a precipitated and denatured state.

Patent DE-3127588-A1 (DE)
Inventor: LEWYN LANNY L
IPC: H03L3/00
Filed: 1981-07-13
Abstract: A very low current Pierce oscillator has two pairs of complementary field-effect transistors (FET's) and a two-terminal quartz crystal. The gates of the first complementary FET pair are coupled through individual capacitors to one terminal of the quartz crystal, their drains being connected together and to the other quartz crystal terminal. Current flow through the crystal oscillator is minimized by a novel oscillator bias loop connected between the gates of the first FET pair. Amplification is provided by the second FET pair which have a commonly connected drain comprising the oscillator output node. The gates of the second FET pair are each connected to a respective one of the gates of the first FET pair. The oscillator bias loop minimizes the source-to-drain current through the first FET pair by reducing the P-channel FET gate voltage in response to the source-to-drain current. The oscillator bias loop assures reliable start-up by permitting the oscillation of the source-to-drain current to increase freely to some large magnitude and then operates to reduce the amplitude of the oscillation and also the dc bias level of the current to an equilibrium condition. Means are provided for preventing elements within the oscillator bias loop from overloading the oscillator or otherwise preventing the initiation of oscillation at start-up.

Title: Skirting board
Inventor: SPAEHN RICHARD
IPC: E04F19/04
Filed: 1981-07-14
Abstract: A skirting board (10) comprises a skirting leg (12) which runs obliquely and is adjoined at the top by an approximately horizontal or slightly inclined covering web (14) which is adjoined by an approximately vertical wall-abutment leg (16), while the lower end of the skirting leg (12) is adjoined by a supporting web (20) which is longer than the covering web (14) and is adjoined by a connecting portion (22) which is bent in an approximately semicircular manner and terminates in a floor leg (24) directed to the front. Wall-abutment leg (16) and floor leg (24) taper in cross-section to the free end in each case and terminate in relatively sharp edges (18, 26). The skirting board permits the carpet edge to be pushed relatively deeply in between the supporting web (20) and floor leg (24), with the result that a precise machining of the carpet edge can be dispensed with. The wall-abutment leg (16) and the floor leg (24) can both be used for fastening the skirting board. After fastening the skirting board, the wall-abutment leg (16) is covered over with wallpaper. The covering web (14) serves, in this arrangement, to guide the cutting blade. <IMAGE>

Title: Process for increasing the fatigue strength of hot-forged components
Inventor: RAZIM CLAUS DR PROF
IPC: C21D7/06
Filed: 1981-09-23
Abstract: The invention relates to a process for increasing the fatigue strength of hot-forged components. These show a forging skin of different thickness, with micro-cracks in the form of so-called forging overlaps. By applying a hardening process, permanent internal compressive stresses are built up in the component within a layer which is close to the surface which is thicker than the forging skin at its thickest point. Expediently, case-hardening is applied for this purpose, and the hardening depth is restricted to about 0.2 to 0.3 mm. Subsequent to the hardening, the fatigue strength can be increased yet further by shot-peening.

Title: Device for the early recognition of the ending of the life of a lead-acid accumulator
Inventor: WINSEL AUGUST PROF DIPL PHYS D
IPC: H01M10/48
Filed: 1982-08-24
Abstract: An initial indication of the end of the life of a lead-acid accumulator is based on the sudden resistance change of a test body which is short-circuited to the positive electrode and whose life history expires precisely at the same time when its total corrosion occurs. In principle, the test body represents a critical conductor piece of increased corrosion susceptibility, for example the pinched limb (4) of a lead grid (life test grid, LTG), having the webs (1, 2, 3) according to Fig. 1. According to Fig. 2, the test grid is schematically placed in an AC circuit with a short-circuit lead (6) to the positive electrode such that its sections form corresponding components of a resistance measuring bridge. The complete corrosion of the resistor (4) (P->PbO2) results in the bridge being mistuned. In this case,  DELTA U is the voltage signal of the mistuned bridge which indicates the corrosion process. <IMAGE>
