Abstract: A disc for mounting a valve onto a spray can which is capable of engaging a standard-sized protective cap such that the cap fills all the space between the disc and the top of the spray can regardless of variations in the thickness of the disc or the seal. The disc has a central body portion and an annular groove disposed at the periphery of the central body portion. The bead of the spray can sits within the annular groove. A seal is positioned between the annular groove and the bead. A spacer is positioned in the annular groove such that the spacial relationship between the bead and the annular groove is predetermined, i.e., the distance between the annular groove and the top of the can is a predetermined distance. Consequently, a standard-sized protective cap can be used for spray cans in which the seal thickness and disc thickness vary, wherein the cap fits snugly on the disc and fills the entire space between the disc and the top of the can.

Abstract: Magnetic media containing data and method for data verification are disclosed. The data verification method utilizes the relative position of specific features of magnetic media signals, such as, peak zero crossings, the ratio of preselected amplitudes, the locii of preselected points along the signal, the RMS value of the waveform and the like. In the preferred embodiment, the ratio of the separation of adjacent pulses in the signal is employed. The deviation of the precise location of the placement of the peak points in the signal waveform is referred to as "jitter". This "jitter" is enhanced to provide a pattern of "jitter" or a magnetic "signature" that is random, non-reproducible and that can be used to positively identify a particular specimen of magnetic media and the associated data. The magnetic jitter pattern or security signature can be separate from or an integral part of the data recorded on the magnetic media.

Abstract: A building (1) where steel plates (2, 8, 9) are used partly as heat transporting elements to and from the constant heat area of the earth which is at a constant temperature and partly as load-bearing elements. The steel plates (2, 8, 9) maintain a significantly higher surface temperature than the outer walls of a conventional building in the winter, and they are insulated (5) on the inner side to below ground level with a high insulation value, thereby making it possible to maintain stay temperature in the interior of the building because of the free heat from the interior of the building and activities of a few individuals as well as from incident sunlight and heat from domestic appliances, light, radio, etc. In the summer, the steel plates serve as air condition by conducting excess heat down into the ground. They may be insulated (10) on the outer side to restrict heating owing to incident sunlight. This insulation (10) also reduces the need for thermal energy from the earth magazine in the winter.

Abstract: In a plate heat exchanger for evaporation of a liquid by means of a heat emitting vapor every second plate interspace forms an evaporation passage (28) and the rest of the plate interspaces form condensation passages (30). Aligned openings (16) in the plates form an inlet channel through the plate heat exchanger for introduction of evaporation liquid into the evaporation passages (28). For enabling use of a large inlet area of each condensation passage (30) and a large outlet area of each evaporation passage (28) the plate heat exchanger is arranged in a container (1), the interior of which is divided in two chambers (6, 7) by the plate heat exchanger itself and a partition (5).

Abstract: The present invention relates to a plate heat exchanger with a number of heat transfer plate (1) arranged between two end plates (3,4). Two guiding bars, which extend from one end plate (3) to the other end plate, are formed in one piece of one and the same rod (5).

Abstract: A method for controlling the cardiac rhythm of a wearer of a dual-chamber pacemaker. A post-atrial atrial refractory period (PAARP) is defined. Any depolarization of the atrium that occurs during the PAARP is defined as pathological. An atrial-ventricular delay is not triggered in response to a pathological depolarization.

Abstract: In a plate heat exchanger for climbing film evaporating of a fluid, vertically arranged heat transfer plates (1, 2) delimit evaporating passages (4) and condensating passages (7) between themselves. Each evaporating passage (4) has a fluid inlet (5) at its lower portion and an outlet (6) for concentrated fluid and generated vapor at its upper portion, which outlet (6) is located at one vertical side of the heat transfer plates. To provide a desired distribution of the fluid and the vapor in each of the evaporating passages (4), at least alternate heat transfer plate (1), in its lower portion (17A) closest to the inlet (5) for fluid, has been provided with a number of zones (23A-26A), having different pressing pattern of corrugation ridges and grooves.

Abstract: A method and apparatus for the continuous production of flexible open cell polyurethane foam, where a process air stream is drawn through the interior of the foam material after it has completed its rise to thereby accelerate the cooling of the foam material. The process air stream contains vaporized constituents which are removed by the steps of:(a) collecting the air stream from the foam material;(b) passing the air stream into an adsorption expansion chamber having a cross-sectional area adapted to reduce the flow rate of the air stream;(c) passing the air stream into an adsorption chamber;(d) passing the air stream through at least one activated carbon char filter bed located in the chamber at a flow rate that is adapted to provide sufficient residence time for the removal of the vaporized constituents drawn from the foam material; and(e) discharging the treated air stream into the atmosphere.

Abstract: An improved currency validator apparatus adaptable to be assembled in either a validator up-stacker, down-stacker, or stacker-less configuration is disclosed. A motor bracket housing and an optics housing interconnect to form a bill passageway. The housings contain optical and magnetic sensors, permit the easy re-positioning of a magnetic sensor and an opposing pinch roller assembly, and preferably are made of a translucent red plastic material. The red plastic material permits the unobstructed transmission of infra-red light from an infra-red sensor, and further acts to indicate the position of the banknote entryway when illuminated by the optical sensors. An improved pinch roller assembly which automatically adjusts to the way in which the magnetic sensor is seated is also described. Further, an encoder positioned on the motor drive shaft, and accompanying slotted optical sensor, provide greater accuracy regarding bill position in the validator.

Abstract: A pump sprayer for pharmaceutical or cosmetic products provides for consistent spray regardless of the orientation of the container. A gravity-actuated valve element coacts with a valve seat to close a secondary passage to the pump when the container is in a normal upright position. In an inverted position the valve opens and the pump intakes from the secondary passage which draws from the area of the top of the container, opposite the primary pump dip tube intake at the base of the container. The valve casing which includes the valve seat has an insertion aperture for the valve element, as well as an axial slot to insure communication of the secondary passage with the pump when the container is in the inverted position.

Abstract: A method of testing a coin in a coin testing mechanism, comprising subjecting a coin inserted into the mechanism to an oscillating field generated by an inductor, measuring the reactance and the loss of the inductor when the coin is in the field, and determining whether the direction in the impedance plane of a displacement line, representing the displacement of a coin-present point which is defined by the measurements, relative to a coin-absent point representing the inductor reactance and loss in the absence of a coin, corresponds to a reference direction in the impedance plane. The reactance and loss measurements may be taken by a phase discrimination method.
