Title: Buffer to temporarily block rail track - has two sections hinged at track sides and biassed to stand-by position by springs
Inventor: WILISCH ERHART DR
IPC: B61K7/18

Title: Gas burner flame failure monitor - uses quartz fibre bundle in flexible tube between quartz lens and radiation detector
Inventor: MOORE WILLIAM J
IPC: F23N5/14
Filed: 1977-06-16
Abstract: A flame failure control system for a gas burner, particularly where the burner is movable employs a radiation detector using an: optical fibre bundle between a quartz lens which is focused on the flame and a remote infra red detector. These optical fibres are extruded non coated quartz fibres which convey the radiation without appreciable loss. The lens is housed inside a casing, and the end of the tube screws into the casing so as to rest against the lens and hold it in position. At this point there are gas circulation openings to prevent clogging by combustion particles and to avoid observing the lens. The tube houses between 30 and 40 fibres of about 0.5 mm diameter. The fibres can convey infra red and ultra violet radiation, the wavelength range being between 2000 angstomes and 2.5 microns.

Title: Harmonica with each reed moving in magnetic field - with variation in intensity of magnetic field to produce special effects otherwise needing different amplifiers
Inventor: DELLA PORTA BRUNO
IPC: G10D7/12
Filed: 1977-09-15
Abstract: Harmonica comprises reeds (3) each of which moves in a magnetic field to cause a variation in intensity of this magnetic field. Each reed is pref. made partly or completely of magnetic or ferromagnetic material, and produces a magnetic field which varies relative to a stationary component held by the instrument body. Pref. magnets (8) coacting with the reeds produce a single magnetic field for the whole instrument, in which the reeds move and the density of magnetic flux varies. The harmonica has means for connection to normal amplifiers already in use, thus allowing utilisation of effects which can be produced by conventional amplifiers (wa wa, distortion, echo, Leslie, tremolo, etc.).

Abstract: Photographic registration materials consist of a carrier with >=2 Ag halide emulsion layers which are sensitive to different parts of the visible spectrum. At least one of the layers contains a Ag halide emulsion (Type I emulsion) which releases a development inhibitor on development of the material. In addition, >=1 of the layers contain a silver halide emulsion (Type II emulsion) which can be inhibited by the released inhibitor. The emulsion grains of the Type II emulsion are more soluble than those of the Type I emulsion, while the Type II emulsion is not matured to full sensitivity, so that after application to a carrier and 6 mins. development at 30 degrees C is an aq. developer contg. (per litre) 2g EDTA, 0.3g 1-phenyl-3-pyrazolidinone, 50g Na2SO3, 6g hydroquinone, 35g Na2CO3, 2.5g K thiocyanate, 2g KBr and 0.015g KI, the fog level is at most 25%. The fog level is defined as the ratio of the amt. of silver present on the carrier after developing and fixing (calculated as AgNO3), to the amount of silver present before development (as AgNO3) multiplied by 100. The prods. are esp. useful as colour reversal materials with improved interimage effect, which give improved colour rendition e.g. of skin tones.
Patent DE-2803150-A1 (DE)
Inventor: NEUMANN DIRK DIPL ING
IPC: H04M19/04
Filed: 1978-01-25
Abstract: The circuit essentially comprises two series-connected circuit sections, of which one section contains a DC-DC voltage converter (T, Tr, D) which operates in the radio-frequency band and supplies an externally controlled high DC voltage. The other section contains a low-frequency generator (G) with an ironless amplifier (V) connected downstream. The DC voltage supplied by the first section is fed to the amplifier as an operating voltage. The necessary DC isolation of the control line and circuit output is implemented in the high-frequency range of the first section by means of a small ferrite transformer (Tr). As a result, the circuit can be designed as a lightweight unit, e.g. using modern slot-in modules with plug-in motherboards. <IMAGE>

Title: Automatic ski lift shackle orientator - has wedge on lever arm turning passing loops into horizontal position
Inventor: SCHIESSL JOHANN
IPC: B61B11/00
Filed: 1978-03-21
Abstract: The downward-moving loop is turned into the horizontal setting, where the loop shackle encounters a lever arm. If a vertical loop encounters this, it is turned, with thrust from a wedge fixed to the arm. When at rest, the thrust wedge lies on a fixed stop, but drops from this at the slightest turn of the arm. It is then sited at loop level, for required thrust, but preventing a horizontal loop from stroking against it because of its initial higher position. The turning device is returned to its original position by a spring, as soon as the loop has passed. The swaying loop is then stabilised by coming against a lightly braked spider flange.

Title: Mechanical heat engine coupled with heat pump - expands air adiabatically and compresses it isothermally, yielding input to heat pump
Inventor: GENSWEIN ALFONS
IPC: F03G7/04
Filed: 1978-03-23
Abstract: Air is drawn from atmosphere (Pu, Tu) and expanded adiabatically in a turbine (1). The exhaust of the turbine is below atmospheric pressure and temp. It is compressed isothermally to atmospheric pressure in a compressor (2) and discharged to atmosphere. The thermodynamic cycle is completed by the constant pressure heating (3) of the air in the atmosphere which returns it to its starting condition. The heat removed from the air during the isothermal compression evaporates a refrigerant in a heat pump circuit. The turbine drives the main compressor as well as the compressor of the heat pump. Useful mechanical work is also available at the turbine shaft.

In the working position the cage is in front of the probe head, so as to catch and hold the concretion.
Patent DE-2830133-A1 (DE)
Inventor: ZULAUF HEINRICH
IPC: E06C7/08
Filed: 1978-07-08
Abstract: The end sides of the rungs are pressed, by a fastening element, preferably a screw (2) which weakens only insignificantly the uprights (1), against their inner surface. Uprights (1) and rungs are designed in such a manner that the latter can neither rotate nor move. By means of this simple connection and by means of correct material selection and shaping, a stable and safe ladder results. Moreover, this type of rungs and their connection to the uprights allows anyone to make ladders themselves, only the rungs having to be bought extra. <IMAGE>
