Title: Disc brake with acoustic wear indication - has spring engaging disc periphery after wear exceeds maximum
Inventor: FRITZ KARL
IPC: F16D66/02
Filed: 1975-08-29
Abstract: The disc brake has a calipper (1) provided with two pins (6, 7) for mounting the back plates (4) of two brake pads (3). A first hairpin spring (8) mounted on the pins has an oval strip (10) extending freely from one of the pins laterally into engagement with the respective backplates to urge them apart. A second hairpin spring (12) also mounted on the pins has a free part pressing radially on the free end of the oval part. As the plates approach one another in the course of wear, the sides of the oval part are pressed together while moving the free end along. Eventually the free part of the second spring snaps off the free end of the oval part and engages the disc periphery there to generate a noise indicating the condition of wear of the brake.

Title: Liquid or gaseous coolants for grinding - introduces coolant as close as possible to cutting point and has very low evaporation point
Inventor: SCHNEIDER HANS
IPC: B24B1/00
Filed: 1975-09-10
Abstract: The method comprises applying liquid or gaseous deep coolants for cooling the very high cutting temperatures at the cutting point of a grinding body during grinding where such a procedure extends the life of the grinding body. The liquid or gaseous coolant is introduced as close as possible to the cutting point. The evaporation temperature is at around -70 deg. C and is thus approximately 400% lower than the temperature of conventional coolants. The coolant is also so passed to the cutting point that this lies in the region of the lowest possible evaporation temperature.

Title: Space heating using coils embedded in floor - has spiralling coils with conducting plates so that walls also form heating surface
Inventor: HAHN GERHARD
IPC: F24D3/14
Filed: 1975-09-15
Abstract: The fluid heating pipe (b) is taken into the room to be heated within the floor near a wall (c). It runs in a coil (a) round the room near the walls, spiralling towards the centre of the floor. The return connection (d) is taken from the end of the coil in the centre of the floor. Thermally conducting metal plates are inserted in the base of the walls at their junction with the floor. The closeness of the heating coils to the walls, and the good thermal contact between the walls and floor result in the wall temperature rising, so that the surface of the walls also acts as a heating surface for the room.

Title: Electron beam irradiation of semiconductor elements - uses electron beams of variable energy for irradiation of sensitive lacquers
Inventor: FROESCHLE ERNST PROF DIPL PHYS
IPC: H01L21/027
Filed: 1976-01-03
Abstract: The electron beam irradiation is used in semiconductor elements production, applying photolithographic methods, utilising electron beam sensitive lacquers. For this purpose the photolacquer mask structures are irradiated by electron beams of different energy, ie the edge zones of the photolacquer masks are irradiated with electron beams of higher energy. Preferably these edge zones are irradiated with an energy corresponding to an acceleration voltage of 15 k V or more. Typically the edge zones irradiated with a higher energy are narrower than 015 microns. The diameter of the electron beam for the edge zones irradiation is smaller than that of the beam for inner zones irradiation.

Title: Iron enrichment of peat prods. - by mixing with finely divided metallic iron and neutralizing to pH 5.5-7.5
Inventor: HUTTER MAX
IPC: C05F11/04
Filed: 1976-01-22
Abstract: In prodn. of (iron-enriched) raw black peat, purified peat, composts, mixed peat fertilizers and other peat prods. from peat contg. tannin, tannic acid and/or humic acid, the peat is treated with finely divided metallic iron and subsequently adjusted to a pH of 5-7.5 by means of alkaline cpds.

Title: Radiation crosslinking of conductor insulating polymer material - using two electron accelerator source at right angles traversed twice by conductor
Inventor: BAEUERLEIN RUDOLF DIPL PHYS
IPC: H01B13/00
Filed: 1976-02-13
Abstract: Polymerisation is for the insulation of the electrical conductors, which have an insulation thickness of a few mm. The system uses high energy radiation and the conductor is passed under the radiation source at least twice. A homogeneous distribution of the radiation doses is achieved without rotating the conductor or cable. The radiation source consists of two electron accelerators displaced at right angles relative to each other. A sector conductor is fed under the radiation sources in such a way that it is symmetrical with respect to the neutral axis between the two sources. The axis of symmetry of the conductor forms an angle of 45 degrees with each of the axes of the accelerators. The passage beneath the radiation sources is repeated after deflecting the conductor through 180 degree about an imaginary axis which is at right angles to the axis of symmetry.

Title: Circuit board short and close-together conducting paths - are arranged on opposite sides to avoid solder short circuits escaping notice
Inventor: KNEIS PAUL
IPC: H05K3/22
Filed: 1977-09-13
Abstract: The circuit board has its major conducting paths on the opposite side from the components. Paths that would lie close together if on the same side of the board are separated and one is placed in the component-side of the board. This prevents inspectors having to decide whether solder connecting together such paths is wanted or not wanted (short circuit). Conducting paths shorter than 5 mm are also placed on the component-side of the board for the same reason as close-together paths are separated.
