摘要： A manually actuated liquid pump sprayer is capable of use in both upright and inverted positions without leakage through the vent port by the provision of a first slider valve which covers an inlet port in the upright position and which uncovers that port when the pump is inverted. A second slider valve located within the pump body is provided for uncovering the vent port in the upright position of spray, and for covering that vent port in the inverted position to avoid leakage.

摘要： The invention relates to a method of generating X-ray images by means of a photoconductor which is provided on a conductive substrate and whose surface potential can be read by means of probes, and also relates to a device suitable for carrying out the method. In order to avoid image artefacts which could be caused by deviating sensitivities of the probes or by frequency-dependent distortions, after the charging of the photoconductor the substrate potential is varied during a test phase. Test data is generated which correspond to the spatial or temporal variation of the potential on the surface of the photoconductor; from this test data there is formed correction data which is stored in order to correct the image data of a subsequent X-ray exposure.

摘要： The invention relates to an arrangement for producing X-ray images, which arrangement comprises an X-ray source (1) for the generation of an X-ray beam (10), a layer (41) sensitive to X-rays and situated on a cylindrical drum (4), and a read unit (5) for converting the X-ray image detected in the layer into electrical image values. In order to improve the X-ray images which can be produced by the arrangement an image processor (21) includes a module (212) for transforming the X-ray image (I) situated on the layer into an X-ray image (I.sub.v) situated in a virtual plane (12), and a module (211) for improving the uniformity of the modulation transfer function (MTF) over the X-ray image produced.

摘要： The invention relates to a method of producing an X-ray exposure is provided by a photoconductor, which converts X-radiation into a charge pattern, is evenly charged locally before the X-ray exposure, is discharged by the exposure as a function of the intensity of the X-radiation and the surface of which is scanned after the exposure for detecting the charge density, an image value being formed for each image point, corresponding to the discharge at the image point. The measured image values may be falsified by the self-discharge of the photoconductor induced by X-radiation. Since the self-discharge always proceeds in accordance with the same time laws, the self-discharge effects are corrected utilizing the time of the scanning instants, i.e., position in time with respect to the X-ray exposure and the end of the charging of the photoconductor in conjunction with a characteristic discharge function of the photoconductor and a correction factor.
