Title: Process furnace temp. and other data detector - uses antenna for selective gathering of radiation energy for evaluation
Inventor: TIURI MARTTI PROF
IPC: F27D21/00
Filed: 1976-07-19
Abstract: The detector arrangement is used for observation and control of temp, quantity configuration and the location of a solid material in a process furnace e.g. in soda drum furnaces and in cement making furnaces. A detector antenna (5) is used for receiving high frequency radiation emitted by the material in the furnace, due to its temp. The various radiation intensities impinging on the antenna (5) from various directions are individually measured or the components of this measured radiation intensities are used for the variation of the quantity and configuration of the material as well as its location. The temp of the material is evaluated at a suitable position.

Title: Heat retaining system for bath tub - uses glass wool mat contoured to bath covering hot water surface
Inventor: BEIKERT MICHAEL
IPC: A47K3/00
Filed: 1976-09-04
Abstract: The heat retaining means for bath tubs comprises a heat-insulated downflow pipe (3) which is attached to the hot water tap by a rubber connecting sleeve (4) and leads down into the bath through an opening in a glass wool mat (5) which is placed in the bath tub. The glass wool mat (5) which is encased in a water-tight plastics foil (6) is raised up by means of floats (7) once the hot water flows in so that the surface level of the hot water is covered by the mat thereby preventing heat loss. In this way much less but other water can be used.

Title: Continuous indolyl-sodium prepn. from phenyl-glycine salt melt - by reacting with sodamide and alkali hydroxide melt in multiple screw extruder, used in prepn. of indigo
Inventor: EGER KNUT DIPL ING DR
IPC: C07D209/34
Filed: 1976-09-29
Abstract: Continuous prepn. of indoxyl-Na, (I), comprises mixing a melt of an alkali metal salt of phenyl glycine with an Na amide/alkali hydroxide melt at 230-250 degrees C in a multiple worm extruder, whereby the melt in mixing- and reaction zone warms up to 260-340 degrees C. After reaction, the melt is discharged. Dwelling times in extruder, after mixing to reaction temp. is 0.5-3 min. The NH3 relased is drawn off in degassing zones. Use of multiple worm extruder allows good mixing of highly viscous melts. Surface of thin layers formed is constantly renewed. Heat released in exothermic reaction is drawn off quickly. No deposits are left in extruder. Process requires a smaller quantity of alkali hydroxide. Yield of (I), indigo quality and indigo yield are not affected.

Title: Real time computer interruption control system - achieves optimum efficiency using time interval or time point selection
Inventor: HENN RICHARD DR
IPC: G06F19/00
Filed: 1976-12-23
Abstract: A time-controlled interruption mechanism for real time computers is designed to achieve greater computer loading and hence efficiency, w.r.t. priority controlled devices. The selection of interruption signals occuring during operation is decided according to time characteristics in for form of response times, in which case time intervals are used, or time limits, in which case time point selection is employed. Time limit operation involves processing at definite times and interval operation involves processing after intervals have elapsed. The two methods achieve the same result when only one processor is used.

Title: Auxiliary air feed for exhaust gas purifiers - in which air feed is increased in response to sudden acceleration
Inventor: MIYAGI HIDEO
IPC: F01N3/22
Filed: 1977-01-11
Abstract: The exhaust gas after burner (10) is provided with an auxiliary air feed (8) supplied by an air pump (5) driven by the engine. The auxiliary air feed is controlled by a regulator valve (9), which responds to signals from an exhaust gas oxygen sensor (11) fitted downstream to the after burner (10) and from signals gained from a clutch pedal switch (17). he clutch pedal switch produces a signal (125) when the pedal is depressed, to increase the auxiliary air feed to the after burner independently to the oxygen sensor (11) dependent signal. The oxygen sensor and clutch pedal dependent signals are fed to an electronic regulator (12) whose output regulates a servo (13). The servo responds to the regulator signals by actuating the auxiliary air feed by pass flap (14).

Title: Self centring coke oven charging hopper - with ball support and internal cover lifting magnet
Inventor: EMRICH JOHANNES
IPC: C10B31/04
Filed: 1977-01-12
Abstract: A self-centring charging hopper for horizontal coke oven chambers rests on three carrier discs which are fixed to the charging car structure. A carrier tube for the hopper has three bearing brackets, fixed to a carrier frame, each fitted with a free-running ball. This compensates for any inaccurate alignment between charging hopper and charging hole. Pref. the charging hopper is suspended on two power cylinders from a carrier frame which is also attached to the carrier tube with the coal charging pipe and three bearing brackets. Each brackets tube is fitted with a spring-loaded ball so that the whole structure can align itself relative to the position of the charging hole by moving along the three carrier discs. This allows the charging hole cover lifting magnet to be housed inside the hopper, so saving time. The self-centring ensures an exact fit and pollution prevention through dust and gas emission by a double seal.

Title: Migraine treatment ergot alkaloid e.g. ergotamine suppository - stabilised by substances releasing sulphur di:oxide, e.g. sodium di:sulphite
IPC: A61K9/02
Filed: 1977-05-10
Abstract: New stabilised suppositories contg. ergot alkaloids and/or their derivs. contain an SO2-releasing substance in fine dispersion in an amt. of 0.2-5 mg. per suppository. Used for treatment of migraine or related headaches. Suppositories are the pref. alternative to oral treatment of migraine (oral medication is often not possible in migraine, and parenteral admin. has to be undertaken by the physician), but ergot alkaloids are generally unstable in suppository formulations. Suppositories contg. SO2-releasing substances, on the other hand, can remain stable for years. In an example, stabilised suppositories consist of 0.325 mg. ergotamine tartrate, 0.500 mg. sodium disulphite, 2.000 mg. butylhydroxyanisole, 5.000 mg. aneurin nitrate, 60.000 mg. caffeine, 100.000 mg. dimethylaminophenyldimethylpyrazolone, and 1190.000 mg. suppository mass.

Title: Mfr. of cement or concrete mouldings e.g. plant pots - using press with heated upper die so that stripping agent on mould contents evaporates onto die
Inventor: HEUSER TONI
IPC: B28B7/42
Filed: 1978-02-04
Abstract: An exact dose of a ductile cement or concrete mixt. (a) is fed into a plastic mould located in the bottom die of a moulding press. The surface of mixt. (a) is then sprayed with a stripping agent (b), and the lower die is raised towards an upper die heated to 300-700 degrees C so agent (b) evaporates and forms a thin stripper film on the upper die; before and during pressing, vibrators are used to assist the compaction of mixt. (a). The pref. press uses a frame fitted with vertical guide bars, along which work cylinders drive a vibrated frame carrying the lower die. The upper die contains electric heating elements and is mounted on a shaft driven upwards against the force of a compression spring. When the moulding (a) has set, it is removed from its plastic mould. Easy sepn. of the upper die from the bore of the pots is achieved.

Title: Transverse fluid preheaters for drying wet cellulosic sheet - to enhance the efficiency of roll press dryers (SW 11.9.78)
Inventor: SUOKAS MATTI
IPC: D21F5/00
Filed: 1978-02-09
Abstract: Preheaters for wet cellulosic sheet passing at an intermediate stage between compression roll driers where the preheating is provided by a stream of hot fluid, pref. steam, released from a manifold within a local hood and drawn past and through the cellulosic sheet to a collection chamber from which the fluid is recycled via an ancillary heater to recompensate for heat lost to the sheet etc. Used for heaters to reduce the viscosity of residual moisture within the sheet and improve the moisture extraction efficiency of a subsequent roll press after some moisture has been removed by one or more preliminary press rolls. The heating effect of the permeating fluid is more efficient than prior art use of the surfaces of a stack of rolls to impart heat by conduction, and the engineering requirements of the design are less stringent and more compact.
