Patent DE-2456751-A1 (DE)
Title: Variable convertor for gas vol measurement - has no moving parts and suitable for very slight temp and pressure variations
Inventor: HOFMANN DIETER DR PHIL
IPC: G01F15/02
Filed: 1974-11-30
Abstract: The period of transverse vibration of a vibrating wire is taken in linear approximation as a measure of the variable of state. The wire is subjected to constant tension and is relaxed through a diaphragm in proportion to the difference between the working pressure and the temperature-dependent pressure of a reference gas in a gas thermometer. Pref. the diaphragm is a metal bellows which undergoes elastic deformation in the axial direction to load the vibrating wire with constant tension. Pref. the nodal point of the wire vibrations is determined by perforated blocks with the seating of the wire in the blocks controlled by slightly off-centre fixing of the wire beyond the range of vibration.

Title: Colour mixing optics for printer - having mixed fibre optics leading to light mixing chamber
Inventor: GRIEGER BERND
IPC: G03B27/54
Filed: 1975-03-14
Abstract: A simple light mixing system for the colour printer has the light from the adjustable filters passing through a solid light to taper to a set of fibre optic guides these are mixed in position and project the light into a tapering light mixing cavity before appearing as an even distribution on a ground glass screen. The system enables relatively few fibre optic filaments to be used thus simplifying the design and providing a more economic equipment. The solid light guide is tapered so that the cross sectional area required by the fibre optics is considerably reduced and made more economic.

Title: Commutator-less DC motor - has stray flux concentrated on magneenggneti% ff flux sensitive element
Inventor: MUELLER ROLF DIPL ING
IPC: H02K29/08
Filed: 1975-04-03
Abstract: Commutator-less d.c. motor with permanent magnet(s) rotor and radial air-gap is proposed with the refinement, that the space between the magnetic flux field sensitive element and the rotor magnets is occupied only by those magnetic flux field influencing elements that concentrate the leakage or stray flux from the rotor magnets onto the same flux sensitive element. This element may be an induction coil or a Hall-effect generator. By this means the stray flux of the permanent magnetic rotor is concentrated in to the magnetic field sensitive element and consequently a sufficient intensity of magnetic field is produced for the commutation control.

Title: Horizontal bar conveyor for festooned piece goods - which rotates bars moving fabric gently through steam or hot air
Inventor: HEIDAN KLAUS
IPC: F26B13/08
Filed: 1975-05-22
Abstract: A device for rotating around their long axes, a number of horizontal support bars, spaced some distance apart and moved by chains or similar along straight or a curved path, esp. for transporting piece goods hanging in loops, through steam or hot air chambers, has, fixed at a laste one end of each bar a disc, arranged at right angles to and considerably larger in diameter than the bar; the discs on consecutive bars being offset axially to each other. Above the rows of discs formed in this way, spring-loaded braking skids are positioned independently of each other, in pairs, so that each skid contacts one disc over a working length corresponding to the length of the circumferential arc through which the disc rotates around the bar, whilst the pitch of two successive discs on the same row, is the same as or larger than the length of zone of the skid. Provides a simple means of turning the bars on their long axes, esp. when heavily loaded, at a moderate speed, uniformly and without jerking.

Title: Radioactive or toxic materials release prevented after accident - by intentional discharge into foam-forming materials
Inventor: MORLOCK GUENTER
IPC: G21F9/00
Filed: 1975-08-28
Abstract: Bursting discs, press. responsive valves or similar discharge devices are provided on the equipment which contains the dangerous substances. The discharge devices lead into discharge pipes, which are connected to receiving vessels. The receiving vessels contain foam-forming substances so that, if a discharge of a dangerous substance takes plate into a receiving vessel, foam is produced by the dangerous substance with or without the assistance of a foaming agent. The dangerous substance thus remains imprisoned in the foam as it hardens.

Title: Heater shell for long workpieces - has split housing with ceramic filling and reflecting surfaces
Inventor: BREUER ERICH
IPC: C21D9/00
Filed: 1975-12-09

Title: Ions-sensitive cell having easily replaceable membrane - with all-round flow, clamped in position by screw
Inventor: BAUCKE FRIEDRICH G K DIPL CHEM
IPC: G01N27/28
Filed: 1976-01-30
Abstract: A through-flow cell for continuous measurements of ions activity comprises a cell block through which a narrow bore conducts the medium to be measured. Perpendicular to the bore is a second, wider bore, in which an ion-sensitive membrane is mechanically fitted with sealing rings, so that a narrow channel is formed around (on both sides of) the membrane for the medium to flow past it. Pref. there are two such wider bores, the second one housing a reference electrode or a second membrane. The two wider bores are pref. parallel to each other. Pref. the ion-sensitive membrane is screwed into the bore and the cell block is of plastic. Standard membranes, made by pressing or crystallisation, canbe used, resulting in a very economical arrangement. Axial pressure is applied to the membrane by a screw, giving a good sealing action and reliable electrode functioning. It is only necessary to undo this screw in order to remove and replace the membranes. Membranes can be rapidly replaced for measurements of different types of ions. Also, several different membranes can be incorporated in a single block, so that activities and concentrations of different ions can be measured simultaneously. Solid or liquid conductors from the membranes can be used with equal facility. Since the duct around the membrane can be made as wide as desired, the adjustment time is dependent upon the setting up of conviction and not of diffusion, and therefore adjustment times of a few seconds are attainable.

Title: Adjustable material-advance mechanism of a sewing machine - is modified to enable a previous setting to be returned to at will
Inventor: LANDWEHR GUENTER
IPC: D05B27/04
Filed: 1976-04-14
