Patent DE-2755603-A1 (DE)
Title: Liquid storage system - with lighter liquid equalised in level with surrounding denser liquid
IPC: B65G5/00
Filed: 1977-12-14
Abstract: A system for storing two liqs. of different densites includes walls defining a liq.-impervious outer chamber, a flexible liq.-impervious membrane disposed in spaced relation to the walls to define an inner chamber contg. the less dense liq., the more dense liq., filling the space within the chambers, and an arrangement to substantially equalise the levels of the two liqs. by overcoming the density differential between them. The two liqs. may be petroleum and water. The density differential may be overcome by loading the less dense liq. with a solid or solid and liq. mass imposed on its upper surface or with fluid press. The system is environmentally safe owing to the less dense liq. being maintained under more than its vapour press., and may be located in abandoned strip mine areas and/or in areas of high water table. Spreading of the liq.-impervous membrane is avoided, and the liq. of the solid and liq. loading mass may be used for fire fighting and/or expelling the less dense liq. from the system.

Title: Device to locate any position on magnetic tape - coats back of tape with reflecting layer with equally spaced absorbing marks identified by detector and counter
Inventor: STOECKIGT GERHARD
IPC: G11B15/02
Filed: 1977-12-19
Abstract: The reverse side of the tape is optically marked. The device has a controllable tape transport system, A photodetector, a pulse amplifier, a binary counter; a register, a binary/decimal decoder and a drive and a visual display.

Title: Sight testing instrument using reflected light - has rotary filter disc for examiner, with and without filter sections
Inventor: BOBIER CLAIR W PROF
IPC: A61B3/10
Filed: 1978-06-13
Abstract: The beam of light(12) from a light source is passed through a lens(13), then reflected by a mirror(16) onto the eye of a patient, for sight testing etc. The eye(20) of the examiner is positioned behind the mirror to receive light reflected from the eye, passing through a non-reflective part(18) of the mirror. Behind the mirror is a rotary disc(22) with a ring of filter openings around it. At least one region of the filter has a relatively high spectral transparency in the region of visible light. The ring can be rotated to place a selected opening in the reflected light path.

Title: Load lowering platform with guides - has flexible drive connected to counterweight via pulley system, with tubular break system filled with liquid
Inventor: SCHEIDING HORST
IPC: B66B9/00
Filed: 1978-07-31
Abstract: The lowering arrangement for loads has platform moving along vertical guides. The platform is connected to a counterbalance with flexible connectors running over a pulley at the top. The lowering arrangement does not use a driving motor and utilises the potential energy of the loads to be moved. It is esp. suitable for mobile applications. The counterbalance arrangement is heavier than the platform. The counterweight, however, is lighter than the weight of the platform and load combined. The platform can be optionally locked in the lower position. The end position of the downward travel of the platform can be adjusted by a stop. On the flexible connectors acts a tubular brake system filled with a liquid. The counterweights move within these tubes as damping pistons.
Patent DE-2835384-A1 (DE)
Title: Automatic volume control for car radio - has microphone picking up noise in car to give control signal and switched OFF at high signal strength
Inventor: FISCHELMAYER HEINRICH
IPC: H03G3/32
Filed: 1978-08-12
Abstract: The device adjusts the volume to the noise level in the car. A microphone picks up the noise level inside the car, and its LF components are converted into an electric interference signal which controls the useful signal level and/or the dynamic level of the signal source. In order to separate the interference from the useful signal, picking up of the noise level is stopped when the useful signal exceeds a level depending on the car type. The noise level before interruption is stored, and holds constant the volume and/or dynamic range.

Title: Prepn. of clear green ammonium poly:phosphate fertiliser solns. - by partial oxidn. of carbon-contg. impurities in the phosphoric acid starting material so the final soln. is easier to filter
Inventor: PETERSEN ALFRED WILLIAM
IPC: C01B25/40
Filed: 1979-07-11
Abstract: Prepn. of ammonium polyphosphate (I) comprises leading an ammonia stream (II) into a tube reactor followed by a stream (III) of phosphoric acid contg. carbon-contg. material and with a P2O5 content of 54-72 wt.% so that (II) and (III) are contacted at 232-343 degrees C for a sufficient time for molten droplets of ammonium polyphosphate to form. Either simultaneously with the entry of the phosphoric acid into the reactor, or up to 15 mins. before this, a nitrate oxidising agent is added in an amt. of 5-95 wt.% of the stoichiometric amt. needed for complete reaction with the C-contg. material present in the acid. Process yields clear, green, ammonium polyphosphate fertiliser solns. The carbon-contg. impurities in the phosphoric have been partially oxidised so that the solns. are easier to filter and the impurities can be sepd. from the clear green solns. Process is simpler and cheaper than previous methods for the removal of the finely divided C-contg. impurities from fertiliser solns. derived from wet-process phosphoric acid.

Title: Self-adhesive soft coating for telephone earpiece - improves coupling to ear and excludes external noise
Inventor: LAUER LUDWIG
IPC: H04M1/19
Filed: 1979-07-12
Abstract: The ear contacting surface (3) of a telephone earpiece earpiece (2) is covered by a circular disc (1) of soft material e.g. velvet, fur on leather. A central hole (8) in the disc permits sound to pass from the perforations (6) in the earpiece. The disc is attached by a self adhesive backing and takes up the curvature of the earpiece. The soft disc is more comfortable to the ear and makes a better sound proof coupling, which improves hearing and excludes external noise.

Title: Ejection of discs punched from holes in sheet metal - involves forming notches with burred edges, so that disc bind together in continuous column ejected through tube
Inventor: HUETER WERNER
IPC: B21D45/00
Filed: 1979-09-28

Title: Super calender conversion - has distance piece inserted in gap between rollers when unwanted upper rollers are lifted
Inventor: SCHUMANN INGO
IPC: D06C15/00
Filed: 1980-04-02
Abstract: The rollers of the super calender are lifted, to bring them out of action, by the lifting cylinder on conversion to a delustering satiniser. The spindle nuts can then be reset. The spindle nuts are moved downwards, before the superfluous rollers are lifted out of action, so that there is an increased gap between the uppermost roller of the wanted section and the lowest roller of the displaced section. At least one distance piece is inserted into this gap to allow the gap to be increased further as the spindle nut is reset for the rollers to be used. When the distance piece is in place, all the spindle nuts are set to the normal gap between them and the limit surfaces on the mounting wall. The gap developed between the rollers is sufficiently larger than the distance piece, to allow its insertion into the gap, to be placed between the two side discs of the flexible rollers and the collar of the hard roller. The mechanism allows a simple and quick conversion of use for the super calender unit.
