A differential input hearing aid with a programmable frequency response provides the hard of hearing with the capability to listen to individual conversations in the midst of high ambient background noise, and to have the frequency response of the hearing aid tailored to the individual user by programming the desired response characteristics into the hearing aid by digital signals. The audio input...

To treat workpieces, construction elements or similar, an air jet laden with granular particles is used, which air jet is accelerated and blown against the workpieces, a wetting additive being added to the air jet. To avoid corroding the treated surfaces and to accelerate the drying thereof, water vapour is used as an additive. The apparatus for implementing such process comprises a compressor (1)...

In processes for the hydrolysis of alkylene oxide to form alkylene glycols in the presence of selectivity-enhancing organometalate wherein the organometalate is provided in a water-insoluble phase, a stabilizing material is used to enhance the stability of the organometalate. The stabilizing material is water-soluble and comprises a cation and a selectivity-enhancing metalate anion.

Novel, ethoxylated lignites which exhibit excellent water solubility as well as solubility in organic liquids are obtained by ethoxylating lignite at elevated temperatures using various weight ratios of ethylene oxide to lignite, the ethoxylation being conducted using an alkali metal alkylate catalyst in a solvent which is generally inert under reaction conditions.

Preparation of alkylation catalysts containing iron oxide and/or chromium oxide, by means of a process which comprises: (a) precipitating hydrate oxides of iron and/or chromium from an aqueous solution of soluble compounds of said elements; (b) separating the thus obtained precipitate, and washing said precipitate; (c) granulating the washed precipitate, and drying the granules so obtained; (d) ca...

A thermoplastic vehicle trim or molding member includes a preferably elongated slot or cavity in one side. A stud or mounting member having an elongated base is inserted into the cavity, heated and rotated such that the elongated portions of the base locally melt, traverse through, and embed themselves into, the surrounding thermoplastic material. The thermoplastic is allowed to cool to form a sec...

Washing machine for washing off or separating plastic film, for example polythene, from paper or cellulose fibers or other pollutants comprising a container 1 into which the material to be washed consisting of plastic film with residual quantities of paper or cellulose or other pollutants is introduced at the same time with the water or subsequently thereto and then stirred by washing mechanical m...

PURPOSE:To prevent the erroneous decision by reducing and transmitting the transmission power when the reception input is lower than a prescribed level at a mobile station to be tested to informing this state to a test device, reducing the transmission power at the side of the test device to avoid the disturbance given to another station and supplying the information on reduction of the transmissi...

The transmission is made up of a symmetrical lower body (101) intended to carry with it a tool, and of an upper box (100) containing front (1) and side (3) shafts intended to be connected to a power take-off. It is possible to swivel this upper box by 180 DEG symmetrically relative to the lower box (101) in order to adapt the transmission to various uses.

Method for the cleansing and decontamination of soil by (a) the extraction of soil contaminated principally by hydrocarbons or other organic material, heavy metals and/or cyanides, by mixing the contaminated soil with water of specific pH as extractant, (b) separating the cleansed or at least partially cleansed soil from the water, (c) separating the contaminants from the water and (d) recirculati...

The three part hinged board vessel, has bow mounted ring (4) and side rings (2,3) for wires passing through ring (4) to the rudder. - The front mounted sail support bridge is secured to the deck by clamps (8). Behind the bridge is an anti-slip surface standing platform, with slot for a sword fitment. Pedals (15) on small rollers (16) are connected to a drive which includes ducts (12) and rods (13)...

An apparatus for generating an aerosol powder from a melt includes an atomization die having an orifice through which the melt passes to create the powder. In a preferred embodiment, the orifice has a dimension less than 5 millimeters, and may include a heater to prevent freeze-off. The die may be included in a high-temperature probe suitable for immersion in the melt, so that accumulated accretio...

Apparatus for treating meat, in particular for the purpose of improving its ability to absorb a curing liquid prior to cooking, comprises a frame mounting at least two spaced-apart side-by-side rollers which are rotated in opposite senses as meat to be treated is passed therebetween. To improve the effectiveness of treatment, the rollers are formed as pressure rollers arranged such that the spacin...

A closed apparatus of potential fluidization type, for conveying powder materials in a dense bed from a storage region (31) to at least one region to be fed therewith, comprising a storage tank (48) for storing the powder material, referred to as a reserve container, which comprises between the two regions at least one horizontal conveyor (33) formed by a lower duct (35) for a flow of gas, an uppe...
