Abstract: In a process for recovering pure methylal from methanol-methylal mixtures, which can optionally contain still further compounds, the separation conducted in a rectification device comprising two rectifying columns. In the first rectifying column, the mixture to be separated is rectified under a pressure lower than that in the second column, into a methylal-rich, methanol-poor distillate, and into a practically methylal-free, methanol-rich sump product. The methylal-rich distillate of the first rectification is then separated in a second rectifying column, operated under a higher pressure than the first rectification column, into a compound stream containing methanol and methylal, which is then recycled to the first rectifying column, and into pure methylal as the sump product. In a specific refinement, the first rectification is preferably operated under a pressure of 1-22 bar absolute and the second rectification preferably under a pressure of 9-30 bar absolute, with the second rectification being operated under a pressure which is at least 8 bar higher than that of the first rectification.

Title: Continuous speech recognition method and device
Inventor: NOJIRI TADAO
IPC: G10L15/12
Filed: 1982-11-10
Granted: 1986-12-04
Abstract: In a system for recognizing a continuous speech pattern, based on a speech pattern entered through a microphone, a feature vector  alpha i is extracted by a feature extraction unit, and a feature vector beta jn is read out from a reference pattern memory. A first recursive operation unit (DPM1) computes a set of similarity measures Sn(i, j) between the feature vectors. A maximum similarity measure at a time point i is determined and produced by a first decision unit (DSC1) and is stored in a maximum similarity memory (MAX). A second recursive operation unit (DMP2) computes a reversed similarity measure. Based on a computed result g(v, l) and the output from said maximum similarity measure memory, a second decision unit determines a boundary vmax. A word Wu based on data u=vmax-1 obtained by the boundary v is stored as nx(x=1, . . . , Y) in an order reversing unit (REV). The order reversing unit finally reverses the order of data and produces an output nx(x=1, . . . , Y).

Filed: 1983-11-15
Granted: 1987-03-12
Abstract: The present invention relates to a method for producing alkalimetal selenite and alkalimetal selenate from metallic selenium through selenous acid. The selenium is dissolved in nitric acid to form selenous acid, which is reacted with an alkalimetal base, to form alkalimetal selenite. The formed selenite is then spray dried. Alternatively, the formed selenite is oxidized at elevated temperature in a basic environment at pH 10-12, with hydrogen peroxide as the oxidant, to form selenate, which is then spray dried.The invention also relates to products produced by the method. The products are intended to be incorporated in animal-fodder or foodstuffs (selenite), or in fertilizers (selenate), to be thus administered to human beings and animals as trace substances.

Title: Hearing aid
Inventor: HENNEBERGER HANS
IPC: H04R25/00
Filed: 1984-06-14
Granted: 1988-06-16
Abstract: A hearing aid has a housing insertable into the auditory canal, wherein the housing contains at least a microphone, an amplifier, an earpiece and a power source. In instruments of this kind it has turned out to be desirable to have, in addition to the usual volume control, an additional control for varying the way the incoming sound signals are influenced by the amplifier (i.e. its characteristic) to adapt to individual hearing impairments. For this purpose the hearing aid provides in the housing space for the battery a pitch control in such a manner that its actuating member can be operated at least when the power source is removed from the instrument. This makes it possible to reduce the space requirement for the pitch control so that even hearing aids insertable into the auditory canal can contain such an additional control.

Title: Apparatus for deinking
Inventor: NANDA ASHOK KUMAR
IPC: D21B1/32
Filed: 1984-04-03
Granted: 1988-07-21
Abstract: In a deinking process for a fibre stock or slurry air is introduced into the slurry so that air bubbles and ink come into contact, and the ink-laden bubbles are then separated from the slurry. 
<??>In order to provide an improved separation process the invention proposes to independently control the air injection, the mixing of the air and slurry, and the separation process by splitting them into separate steps so as to optimise the separation process. 
<??>Thus, there is provided a separation cell (31) which is fed with slurry from an inlet, an air inlet device, which in one embodiment comprises a porous sintered sleeve (7) to which air pressure is applied, and a mixing section which imposes turbulent flow on the air bubbles and slurry by passing the constituents through a series of turbulence discs (39). The resulting mixture enters the separation cell where the ink-laden bubbles rise to the surface as a foam which is conveniently removed by suction. The reinked slurry being drawn off from the separation cell.

Title: Insole
Inventor: ANGER WOLFGANG DIPL ING
IPC: A43B17/08
Filed: 1984-10-17
Granted: 1989-02-09
Abstract: A foam latex insole includes a number of ribs on its undersurface. The ribs face the top-sole of a shoe when the insole is placed therein, and are formed of foam latex which is closed-pored and somewhat firmer than the foam latex which forms the continuous part of the insole. The ribs can be straight, curved or sharply bent, and form a labyrinth of ventilation channels between the top-sole of the shoe and the underside of the foot. The arrangement of the rib is such that a pumping effect is developed in response to pressure changes on the insole which promotes the exchange of air within the shoe to maintain a suitable environment for the feet.
Patent DE-3483679-D1 (DE)
Inventor: PIERREL HANS-JOACHIM
IPC: H04M19/08
Filed: 1984-09-17
Granted: 1991-01-10
Abstract: The invention relates to a circuit for a telephone station which is mains-supplied or remote-powered as required, i.e. in the event of a mains failure an automatic switchover from the mains voltage to remote power takes place, and a switchover in the opposite direction takes place when power is restored. This is effected without any additional voltage insulation and without substantial additional expense. This is achieved in that a switching regulator which establishes the actual feed voltage is connected to the mains DC voltage, where a blocking voltage for a transistor located in the remote feed unit is obtained from the mains DC voltage. If the mains fails, the blocking voltage for the transistor is also lost and the latter is switched through by the remote feed voltage which acts upon its base. This procedure is automatically reversed when the main voltage again becomes available.

Abstract: Transfer of garments, having limp portions, from one machine (L) to another machine (T) the needs of which demand that the limp portions are separate for delivery to separate receiving members therefor, is accomplished while the garments are moving in the direction of the receiving machine (T). The limp portions of the moving garment are draped over a guide rail (28); a second guide rail (30) is encountered by the limp portions, this rail being positioned to interpose itself between the advancing limp portions, with the result that one limp portion becomes draped over each rail. Thanks to a subsequent divergent between the rails (28, 30), the said portions are separated from one another and are guided by the rails in this state to the intended receiving members (12 min , 12 sec ). Adjacent the receiving machine (T), the apparatus includes positive drive means (40) constituted by driven endless loops (42) which seize each limp portion and advance them individually with precision to their allotted receiving members (12 min , 12 sec ). The invention is particularly applicable to pantihose manufacture e.g. for transferring part-finished pantihose garments from a line closer to a toe closer.
