Abstract: A buckle folding machine with at last one pair of folding rollers and at least one folding pocket (1). The folding pocket includes a top rail (43), which extends over the width of the folding pocket (1) and is attached to lateral toothed belts (26, 27) and has, on its side facing the folding pocket mouth (9), a plurality of stop fingers (44). The stop fingers have front end faces (48), located in a common plane, serve together as a paper stop within the folding pocket (1), and which can be brought by the toothed belts (26, 27) into a front deflecting position, in which their front end faces (48) together act as a paper deflector and guide the material arriving at the folding pocket mouth (9) for folding past the folding pocket (1) and into the next folding station (F2).

Abstract: A breathing mask with a fan for feeding respiration air into the interior space of the mask has a flow indicator for indicating a necessary respiration air flow at the air outlet end of the fan connection. In order for this indicator to be directly recognizable by the mask user in his field of vision, the opening of the air outlet end (4) shall be closed at least partially by a flow plate, which is movably mounted on a guide structure (11, 20) such that it emerges into the field of vision of the mask user in the presence of air flow, and guides the respiration air flow along the inner side of the window (10). If the respiration air flow is insufficient, the flap jumps back, and warning windows appear, instead, in the range of vision of the mask user.

Abstract: A voluntary control, intended to obtain an increase in retinal reflection, is carried out using an auditory biofeedback technique based on the measurement of retinal reflection, for the purpose of achieving an improvement in visual perception in its principal functions; the method includes the following phases:periodic measurement of the retinal reflection and of its variations, independently of factors concerning ocular optics;production of a tone representative of such measurements, which informs the patient as to the condition and as to the variations of his own retinal reflection;instruction on voluntarily increasing the retinal reflection by means of the voluntary control of the biofeedback tone.

Abstract: The cathode of an electron gun is connected to the body of a space vehicle, performing an automatic limitation (or neutralization) of the negative potential (measured with respect to the physical entity toward which the electron beam is directed, i.e. the anode (A) of the gun, whether this be the environment in which the gun is immersed or a particular object such as a second space vehicle) which the body may assume in the absence of the connection referred to. The aforementioned negative potential is limited or neutralized by means of the extraction of negative charges emitted from the gun (K-E) in the form of an electron beam under appropriate conditions of vacuum. The gun comprises a cathode (K) to be connected to the body (C), at least one accelerating electrode (E), an accelerating voltage generator (G) and a generator (R) for heating the cathode.

Abstract: A ball joint for chassis parts in motor vehicles is described, in which a hinge pin 1 with a spherical part 2 is mounted in a housing 3 by a bearing box 4. The hinge pin is led through an opening 6 out of the housing 3. The housing 3 is sealed by a lid 7, on the opposite side. In this case, the housing is placed in a rigid external bushing 10 with an elastomer sleeve 9 surrounding the housing. Radial surfaces on the housing 3, as well as on the external bushing 10, limit the axial movement of the housing 3 with respect to the external bushing. The radial surfaces of the housing 3 are formed by the two flat sides of a collecting plate 15, which can be firmly connected to the housing 3 first in the assembly of the joint. The collecting plate 15 engages with an axial moving space between arranged radial surfaces of the external bushing 10.

Abstract: A writing board ink composition comprises a medium formed of a lower alcohol solvent which contains an alcohol-soluble polymer, a scraping (erasing) agent, a surfactant and a diketopyrrolopyrrole pigment having a median Stokes diameter (ultrafine particle size) of not more than 0.2 .mu.m and represented by the following formula ##STR1## R.sup.1 and R.sup.2 independently represent an unsubstituted phenyl or naphthyl group of a non-water-solubilizing substituent substituted phenyl or naphthyl group, and R.sup.3 and R.sup.4 independently represent hydrogen or a non-water-solubilizing substituent. The writing board ink composition remains stable for a long time while in pens even when the resin content (alcohol-soluble polymer) is such that unclear writing and scrapability reduction (loss of scrapability or erasability) can be avoided, since the pigment of ultrafine particle size is fast to lower alcohol solvents.

Abstract: A dispenser cathode with multilayer sintered body is suggested, wherein the layers have a thickness of between 0.01 and 10 mm and have different compositions.

Abstract: The present invention pertains to a process and a device for packing pressed bales with a film and by strapping, wherein the pressed bale is maintained under pressure between pressure rams while the packing is applied. The packing device 1 has an enveloping device 5 and a strapping device 6, which are arranged on separately movable transport carriages 8, 9. The packing film is pulled off from a single film roll 10 on the other transport carriage 9 by means of a movable film arm 5 located on one of the transport carriage 8, and is placed in a U-shaped pattern as a belly bandage around the pressed bale 2. After cutting off from the roll 10, the film ends are then placed loosely over each other with an overlap by means of a second gripping arm 20, and fixed by strap hoops.

Abstract: A coupling device for establishing a detachable connection for a tube system is to be improved so that while simple detachability of the pipe socket and tube is guaranteed, the pulling-off force is equivalent to firm clamping. To accomplish the task, a sleeve-like coupling box 7 is provided, which surrounds the tube 5 in a clamp-like manner and, for fixation on the pipe socket 2, it has, on the inside, a circumferential notch 8, into which two oppositely arranged projecting parts 4 of the pipe socket 2 snap. The coupling box 7 expands under the effect of a force acting laterally, so that the projecting parts 4 will disengage from the notch 8.

Abstract: A pressure-measuring head for measuring the pressure of a fluid consists of a membrane-like diaphragm (6), which separates a pressure chamber (4) from a reference chamber (7), to which the pressure-sensitive elements, e.g., thick-film resistors or strain gauges, are applied. Under the effect of the pressure in the pressure chamber, these pressure-sensitive elements perform a deflection which is proportional to the pressure occurring in the pressure chamber. An electric contact is switched during simultaneous displacement of the membrane (6) arranged in a sensor housing by a predeterminable distance (19) after a defined pressure value has been reached in the pressure chamber. A measuring head of such a design is also able to assume a swithing function without additional auxiliary energy, besides sending an electrically processable pressure signal.

Abstract: A miniature motor having a housing formed into a bottomed hollow cylindrical shape. The inner circumferential surface to which a pair of permanent magnets, which are rare-earth plastic magnets of an essentially C shape in cross section, are fixedly fitted. An end cap is fitted to an open end of the housing, and a rotor is rotatably supported in the housing by bearings provided on the housing and the end cap. A pair of the permanent magnets are formed in such a manner that the magnetic force of each magnet is made different from each other so that the rotor can be attracted to the permanent magnet having a larger magnetic force. One of the permanent magnets is made of a rare-earth plastic magnet containing a coloring material.
