Patent DE-2356514-A1 (DE)
Title: Quick action switching system direct or alternating current supply - had disc shaped air cored coil attracting coaxial magnetic material armature disc
Inventor: STURM HERMANN
IPC: H01H50/20
Filed: 1973-11-13
Abstract: Quick action switching system for relay or safety trip may be connected to a d.c. or a.c. source. There is a fixed drive coil on a shaft which produces a magnetic field to attract an armature which operates the contacts. The drive coil is air cored and is wound in the shape of a disc. The armature is a ferromagnetic disc mounted coaxially on the same shaft but is free to slide when attracted or released by the magnetic force of the drive coil. The armature is backed up on the same shaft by another disc made from copper and with a higher electrical conductivity. It is mounted so that it is also traversed by the magnetic field.

Title: Reagent for colorimetric detection of pyridine (derivs) - comprising aconitic or citric acid and a condensing agent
Inventor: LANG ERNST DIPL CHEM DR
IPC: G01N31/22
Filed: 1974-02-01
Abstract: A reagent for colorimetric detection of pyridine and its derivs. is prepared by (a) adding to a solid, gelled or liq. carrier aconitic acid (I) or citric acid (II) or their derivs. and (b) using as second component a condensing agent e.g. a mixt. of acetic acid and acetic ahydride. The reagent is specific and gives yellow, red or violet-red to red violet colours in a few sec to mins. No heating is required; the components are relatively harmless and non-polluting and the reagent may be stored in liq. or solid form without appreciable deterioration. By using a standardised colour scale the method can be made (semi)quantitative.
Patent DE-2407490-A1 (DE)
Title: Rotary steel-wire brush with elastomer base - comprises wire-bundles, evenly distributed in elastomeric carrier
Inventor: SCHAAK FRANZ-WERNER DIPL ING
IPC: A46D1/00
Filed: 1974-02-16
Abstract: The wires are shaped into bundles and the bundles are evenly distributed in the elastomer material. This prevents outward shifting of the wires, when the hollow body of the brush is being filled. Preferably the wires in each bundle are twisted together or are made up in the form of a braid. Each bundle has one component wire wound around the outer surface in a spiral pattern. The embedded bundles of wires which may be secured by means of adhesived or edging material, is then assembled into a cylindrical member so that the above edging material is at one end and a hollow cone contour is at the other.

Title: Sinter bodies for electrical condensers - by sheeting mixt of valve metal and polymer binder, compressing, welding anode wire and sintering
Inventor: BUB HUBERTUS
IPC: H01G9/052
Filed: 1974-04-13
Abstract: A sinter body for an electrical condenser is prepd. by (a) mixing a valve metal, esp. Ta, with a film-forming org. polymer binder, dissolved or dispersed in an org. solvent or water, to give a pourable compsn., (b) casting in a mould and evapg. the solvent to give a coherent, workable sheet, (c) compressing the sheet by rolling or pressing (d) solidifying the sheet, or parts cut from it, by sintering, after removal of remaining solvent and binder such that an anode junction wire of valve metal can be welded onto the body, opt. in an atmos. of protective gas, and (e) after welding the junction wire, subjecting the body to final sintering. Bodies of more uniform density and better electrical props., e.g. residual current and tan S, are obtd. The density can be varied by altering the press. during rolling or pressing. Smooth, easily processed, solid electrolyte bodies are produced. The thickness of the sinter body is not limited by the dia. of the junction wire. The grain size and condition of the metal powder are less important then in known methods. Metal powder is not sintered onto the junction wire.
Patent DE-2418905-A1 (DE)
Title: Filament strand impregnating device - in which opposite charges are induced upon strand and impregnating particles
Inventor: BROWN ALFRED WINSOR
IPC: C03C25/12
Filed: 1974-04-19
Abstract: Strands made up of filaments are impregnated by moistening the filaments of the strand to form a semiconductive coating thereon, applying an electrostatic charge to the filaments to cause them to separate and passing the separated filaments through a fluid bed of impregnant particles carrying a charge of opposite sign to that carried by the filaments. The different charges cause the particles to be attracted onto the filaments. The filaments are passed through a device which coalesces the particles and are finally formed back into a strand. The process is useful in preparing strnds for use in article reinforcements and ensures that each filament of each strand is coated. The filaments may be changed by passage over an earthed or line electrode or by passage through a cylindrical electrode.

Title: Continuous track vehicle face seal - comprises two sealing flanged rings held together by wholly rubber retainers
Inventor: NEGRO GIORGIO DR
IPC: F16J15/34
Filed: 1975-01-16
Abstract: The face seal for continuous track vehicles has two sealing rings held together coaxially by flexible components. The rings are circular with a central hole to accommodate continuous track rollers. On their outer periphery, there is a flange connected via a blunt-conical section to a smaller shoulder. The turned away surfaces of the flange acts as friction surface for the opposing corresponding surface of the other ring. The flexible components which hold the rings together are entirely constructed from rubber without reinforcement. The blunt-conical and shoulder sections of the ring periphery have a high friction value in relation to the flexible retaining components whilst the turned away surface of the flange is finely ground.

Title: Solar cell for heating and hot water systems - preventing furring and winter freezing of pipes
Inventor: WENDEL WALTER
IPC: F24J2/04
Filed: 1975-08-19
Abstract: Solar cell for heating and hot water system, using water, comprises a heat conductor (2) made of metal, and an isolating switch which prevents backflow of heat from the boiler. The insulated asbestos cement housing (1) and the Al sheet cover plate (4) are weather resistant and aid heating of the Cu collector plate. In an example, the sun rays are focussed by means of glass lenses and transmitted to the collector plate. If there is no sunlight, an automatic switch isolates the heat conductor and prevents backflow of heat. In an alternative embodiment without glass lenses, the housing is covered only with the Al sheet, and conduction of heat is performed as above.
