Patent EP-0038018-A1 (EP)
Inventor: WILLEITNER EBERHARD ING GRAD
IPC: F25B43/02
Filed: 1981-04-08
Abstract: An oil separator comprising an elongated horizontally oriented container having an inlet near one end through which an oil-refrigerant vapor mixture can be introduced into the container, the container having outlets near its other end for the separated oil and refrigerant vapor, respectively. A deflector is located within the container in the flow path of the oil-vapor mixture, and there is a demister within the container downstream of the deflector. The bottom of the container constitutes an oil sump, and a partition within the container has an opening in its portion within the sump, the partition carrying the demister at a location above the oil level in the sump. The cross-sectional flow area of the demister is smaller than the surface area of the partition above the oil level. The length of the demister is sufficient to permit oil drops in the oil-vapor mixture to unite with oil clinging to the demister mesh. Two spaced apart demisters may be used. In an alternative embodiment, a second container extending into the elongated container has the oil-vapor inlet and a perforated bottom above the sump oil level. Within the second container is an annulus, a stilling chamber, and a demister downstream of the annulus. A heater and/or a cooling device may be located within the oil sump.

Abstract: An electrochemical anemometer (10 or 50) is provided for measuring electrolyte motion, e.g., relative local motion of oxygen-dissolving aqueous electrolyte, e.g., sea water or brackish water. The anemometer includes: (a) a housing (11 or 51); (b) an exposed first electrode (14 or 52), e.g., of silver, attached to the housing; (c) an exposed second electrode (13 or 53), e.g., of platinum, attached to the housing (11 or 51) and spaced apart from the first electrode (14 or 52); (d) an amplifier (110) having input and output disposed in the housing (11 or 51) and having its input connected either to the first electrode (14 or 52) or to the second electrode (13 or 53); and (e) an electrical power supply (110) to the other of the first electrode or the second electrode and to the amplifier means, and for conducting the output of the amplifier to a display for the signals of the output. In this way, the signals are proportional to the oxygen transport rates, which are, in turn, an indication of the relative electrolyte motion in the region of the electrolyte adjacent one of the electrodes.

Abstract: This invention relates to an arrangement for attaching discrete electrical components to a generally flat layer of sheet material. Both mechanical and electrical connections are provided by the attachment elements of the present invention. One form of the invention is directed to a membrane switch keyboard wherein one of the layers of the membrane switch has a tail extending therefrom. The tail has a free end which is adhesively secured to some portion of the keyboard. Conductive traces are formed on the tail and extend to the free end where they contact the leads of an electrical component. The component is held between the tail and the keyboard. In another aspect, which may be applied to the membrane switch keyboard just described, the invention includes a sheet material having two or more slits cut therein for each of the component's leads. The slits are cut in a portion of the sheet having conductive traces formed thereon. The leads of the component are then interlaced through the tabs created by the slits to both mechanically and electrically connect the component to the sheet.

Abstract: In the invention, a plurality of fire sensors are allocated in parallel on a two-wire line via which at the same time the supply voltage for the fire sensors is provided. The measured value is formed by connecting, under the control of a local pulse generator, a measured value shunt to the two-wire line in order to generate measured value pulses. Each measured value generator (3, 4) is provided with a pulse generator (11, 12) programmed to emit an individual pulse code. The pulse code serves in the central station as an address which can be evaluated behind a first threshold value switch (21). At the end of the two-wire line (1, 2) facing away from the central station (6), there is a monitoring shunt (16, 17) which is permanently connected through by pulses by means of a pulse generator (15) also arranged at this end and , specifically, in order to generate monitoring pulses (15) which can be evaluated in the central station (6) behind a second threshold value switch (22). The amplitude of the monitoring pulses (15) and the threshold value, exceeded by them, of the second threshold value switch (22) is substantially smaller than the amplitude of the pulse code and the threshold value, exceeded by the latter, of the first threshold value switch (21). <IMAGE>

Abstract: Heavily perfumed detergent compositions having both immediate and long lasting perfume emitting properties are prepared by a process in which perfume is emulsified in a water solution of water-soluble polymer, and the emulsion is mixed with a powdered hydratable material, in such a ratio that all of the water in the emulsion can be bound in the resulting hydrate, eliminating a separate drying step. The result is a dry, free flowing granular material which can be readily dry mixed into fully formulated detergent compositions. The perfume is retained in the polymeric matrix and is released at the point of product use when contacted with water.

Abstract: Printing apparatus suitable for use as a dot matrix printer is provided with an elastic medium, such as an elongate metal or alloy member 18, extending across the print field, the member being associated with some form of ink deposition mechanism (not shown) such as an inked fibre provided on the member, or a trough arrangement containing ink. Pulses P., P m  are transmitted in opposite directions along the member 18, either from two transducers T 1 , T 2  or from one transducer in two series of pulses, the first being reflected at the end of the member opposite the transducer and returning to meet the second series. The pulses travelling in opposite directions combine constructively to provide momentary stationary impulses P c  which actuate the ink deposition mechanism. Pulses of smaller amplitude do not actuate the mechanism thereby avoiding spurious printing. Thus relative timing of the pulses produced by the transducer(s) will determine the positions of the printed dots.
