Patent EP-0215572-B1 (EP)
IPC: B05B9/01
Filed: 1986-08-12
Granted: 1990-10-10
Abstract: There is a disclosed an improved spray tip for airless spraying of liquids in which the spray orifice (32) is mounted in a rotatable turret member (14) which is captured in a subassembly of a plastic spray guard (10) and a tubular metal housing (12). The housing (12) has a longitudinal through passageway which receives a floating piston seal member (90) that has a forward, cylindrically concave face (100) which is urged into a tight seal against the rotatable turret member (14) by the liquid pressure which acts on the upstream face of the floating piston seal member (90). The floating piston seal member (90) is sealed in the longitudinal through passageway by an annular seal (104) which also restrains the seal member (90) against rotation when the liquid pressure is released, thereby freely permitting substitution of spray orifices by interchanging of turret members (14). The turret member (14) includes a handle (16) with a dependent prong (24) which is reveived through a slotted aperture (42, 44) of the spray guard (10) into an internal cavity (56) of the spray guard body having one side wall (60) with shoulders (62) which provide abutment stops for the turret member, thereby aligning its transverse bore with the longitudinal passageway through the housing.

Abstract: In a hearing aid system, selected optimum parameter values are programmed into an electronically erasable, programmable read-only memory (EEPROM) (84) which supplies coefficients to a programmable filter (64) and amplitude limiter (67) in the hearing aid so as to cause the hearing aid to adjust automatically to the optimum set of parameter values for the speech level, room reverberation, and type of background noise then obtaining. The programmable filter may be a digital equivalent of a tapped delay line in which each delayed sample is multiplied by a weighting coefficient, and the sum of the weighted samples generates a desired electro-acoustic characteristic; or a tapped analog delay line in which the sum of the weighted outputs of the taps generates the desired characteristics. Acoustical feedback is reduced by an electrical feedback path in the hearing aid which is matched in both amplitude and phase to the acoustic feedback path, the two feedback signals being subtracted so as to cancel each other. Alternatively, a single filter in the forward path may be used for this purpose with a transmission characteristic equivalent to that of the programmable filter in the forward path plus the electrical feedback path. Also, the relative speech-noise content in the signals from the hearing aid microphone is sensed and binary words are generated and supplied to the programmable filter for selecting from memory a set of delay line tap coefficients that are effective to impart to the filter the appropriate frequency response for the specific environmental noise condition being detected.

Abstract: A condensation process and apparatus for water vapor under vacuum which is taken preferably from a drying apparatus. The vacuum is produced by a water ring vacuum pump through which water flows, and the water vapor in the liquid ring vacuum pump is condensed into the liquid. The water is carried in a water circuit with at least one heat exchanger yielding heat from the water for heating purposes. Before flowing into the water ring vacuum pump, the water carried in the circuit is passed through a heat exchanger transferring waste heat from the pump and the pump drive to the water. Heat losses are prevented by a casing of thermal insulation surrounding the pump as well as the heat exchanger.

Title: Flexible slab for railroad level-crossings
IPC: E01C9/04
Filed: 1988-02-25
Granted: 1991-08-28
Abstract: Elastic plates for level railroad crossings have rail-adjacent edges which are profiled in their vertical cross sections to provide the required interlock. The plates have a first pair of grooves in the top and the bottom of the plate running parallel to the rail and have a second pair of upper and lower parallel grooves in the top and the bottom of the plate running transverse to the rail. In each pair of grooves, the groove in the top of the plate is laterally offset with respect to a parallel groove in the bottom of the plate, and each pair of grooves forms an expansion and contraction crease therebetween. Pairs of grooves in the top and the bottom of the plate are spaced, so that the distances between individual expansion creases, or between expansion creases formed by groups of creases, are large relative to the distance between the grooves which constitute the expansion creases. The first and second pairs of grooves intersect one another and in order to prevent an aperture or opening from being formed in the plate at the points of intersection, an integral layer of material is provided at each intersection to seal between the upper and lower sides of the plates.

Granted: 1990-10-03
Abstract: In gas-cooled electric machines with a closed cooling loop which is distributed over two heat exchangers, arranged on the upper or under side of the machine, only part of the circulating cooling gas is cooled so that the electric machine must be taken out of operation because of the danger of local ovewrheating. In order to overcome this, baffles are arranged adjacent to the heat exchangers so as to block the cooling gas on half the side of the opposite axial cooling gas passage regions of the heat exchangers, thus subdividing the cooling gas stream into two halves with opposite flow directions. The partial transfer of the cooling gas stream halves to the entire width of the axial cooling gas passage areas of the heat exchangers provides turbulence and a distribution of the cooling gas for uniform cooling also in the event of a failure of one heat exchanger.
