IPC: C01C1/04
Filed: 1986-12-20
Abstract: In an NH3 reactor, especially with at least two heat exchangers concentrically arranged axially one after the other and catalysts beds surrounding these heat exchangers, it is intended by comparatively simple constructional means to provide optimum preheating and flow within the vessel for the circulating gas and/or process gas, while maintaining perfect cooling of the vessel wall, it being possible for the vessel in particular to have more than two catalyst beds.

Title: Skip hoisting system
Inventor: JONDRO BOLESLAW
IPC: B66B17/08
Filed: 1987-03-18
Abstract: This skip hoisting system is intended in particular for hoisting minerals from the level of the pit eye of a mine to its pit mouth. When loading and unloading hoppers of the skip hoisting system, crushing of the minerals should be avoided, to prevent reduction in value and the nuisance of dust being raised. The skip hoisting system has six hoppers of identical construction and effect, of which two loading hoppers are built into a chamber at the pit eye, two skip hoppers in a support structure of skips, and two unloading hoppers at the pit mouth. The individual hoppers each consist of an upper segment, in which a movable lower segment is arranged in a liftable manner, having a movable rotatable bottom. <IMAGE>

IPC: G01B21/04
Filed: 1987-06-13
Abstract: The invention relates to a shape measure for checking the accuracy of coordinate measuring machines. In order to provide a shape measure which can be used as universally as possible and is also suitable for simulating complicated radially symmetric three-dimensional surfaces, the invention envisages providing a base plate, which rests on the table of the coordinate measuring machine, is constructed as a precision pivot bearing and is provided with a test piece, with scanning points for determining position in the coordinate system of the coordinate measuring machine, and that the rotation angle of the base plate can be set exactly with respect to a starting position. Moreover, the test piece is arranged obliquely in space on the base plate and its position is known down to the ppm region. In this case, the test pieces are furnished as simple geometrical shaped elements which can be produced with high precision and have uniformly curved shaped surfaces.

Title: Actuation of a pen of a line-drawing device in typewriters or similar office machines
Inventor: KITTEL ARTHUR ING GRAD
IPC: B41J29/26
Filed: 1987-07-16
Abstract: Line-drawing devices on typewriters for drawing horizontal and vertical lines are already known in many designs. The fact that they are hardly ever encountered in practice ought to be sufficient evidence of them not proving to be expedient or of obstructing the writing operation too greatly. This disadvantage is avoided by an ink-ribbon cartridge with a displaceable pen which is arranged in a cutout in the cartridge housing so as to be displaceable and lockable by hand in two end positions. If, in this case, lines are to be interrupted, the pen is to be engaged with and disengaged from the recording medium by hand in each case. The invention is based on the object of allowing lines to be produced with few manipulations. This is achieved in that the displaceable pen (16) is in positive-locking engagement with power transmission members which can be operatively connected to and disconnected from an electromagnet (57), provided for transporting the ink ribbon (10), by means of an operating element (39) which can be actuated by hand, and in that the ink-ribbon transporting members can be moved alternately out of and into the operative range of the electromagnet (57). An electromagnet (57) which is already present selectively takes over either the transporting of the ink ribbon (10) or the engagement of a pen (16) of the line-drawing device with the recording medium (1). By deactivating the electromagnet (57), ... Original abstract incomplete. <IMAGE>

Patent DE-3740652-A1 (DE)
Title: Device for improving the side tone suppression or loop gain in intercom systems
Inventor: GENUIT KLAUS DR
IPC: H04B3/20
Filed: 1987-12-01
Abstract: In a device for improving the side tone suppression or loop gain in intercom systems, it is proposed to leave the propagation constant constant in the low-frequency transmission range and to carry out voice-level-dependent control of the gain in the low-frequency range with distinction between simplex and duplex speaking, the sum of the gains remaining constant in the transmitting and receiving direction. Alternatively or as a supplementary measure, the method of an (adaptive) echo cancellation, which is known per se, can be used for achieving adequate loop gain in the low-frequency range. Finally, it is possible to control the pass-bands and stop-bands of the band filters involved speaker-dependently over the entire transmission range in such a manner that in the case of pure duplex speaking, the signal of the transmitting subscriber is transmitted unfiltered and the signal on the other party is attenuated by the amount of the desired increase in loop gain, whilst, in the case of simplex speaking, the gains of the individual band-pass systems are controlled in dependence on the respective voice level, in such a manner that the stop-bands of the filter transfer functions of the louder speaker in each case are attenuated less and the pass-bands of the inverse filter transfer functions of the quieter speaker are correspondingly attenuated more.

Abstract: The invention relates to a device for developing an electrographic image and is used in the modular treatment of films. It is provided that a specific filling container is arranged above the developing chamber which is perpendicularly arranged and whose closable feed line leads into the developing chamber from below, in which developing chamber the liquid paths then branch off according to the principle of communicating pipes. The complexity in terms of control and regulation is thus reduced while ensuring high functional reliability and at the same time shortening the developer guide paths in the direct functional area. <IMAGE>

IPC: G01N21/55
Filed: 1989-07-19
Abstract: A continuous determination of differences in gloss together with those in colour, e.g. in a production line of lacquer spraying of refrigerator cabinets, is achieved by passing the workpieces beneath a HeNe-laser (1) which emits intermittently a beam of 0.25 mm dia. the reflection of which (4) reaches a sensor (5) with two photosenstive semiconductor layers. The diffuse reflection from a polychromatic tungsten lamp reaches the sensor in the intervals between the laser reflections. A modulator (2) controls the periodicity. The laser reflection produces a sensor output which assesses the gloss and that of the polychromatic radiation (350-750nm) that of the main criterion of the radiation e.g. the colour.
