Title: Operating process of an equipment arrangement combined from a laser transmitter and a thermal imager as well as an apparatus for this
Inventor: KARNING HEINRICH
IPC: G01S17/86
Filed: 1983-08-16
Granted: 1984-10-18
Abstract: In the case of an operating process of an equipment arrangement combined from a laser transmitter and a thermal imager, the associated optical axes (11; 12) are aligned parallel to each other; in addition, there is only one common thermal image/laser receiving channel (8 to 11). Since the angular movement of the mirror (8) scanning the incident radiation has to be taken into consideration in a distance-measuring operation, unless the narrow-band CO2 radiation is coupled out ahead of the mirror, which is not always possible for design reasons, a synchronising means (1 or 2, 3 or 4), compensating this angular movement, is provided on the receiving side and/or emitting side in the path of rays (Fig. 1). <IMAGE>

Title: Hydraulic earthworks vehicle with a slewable boom
Inventor: THIEME GERHARD
IPC: E02F9/12
Filed: 1985-03-12
Granted: 1986-07-10
Abstract: The slewing unit for an excavating arrangement of a vehicle, in particular for working the bank areas of stretches of water, contains a slewing platform (21) which is mounted on a vehicle chassis (22). Fastened to the slewing platform (21) is an excavating arm (20) which can be lifted and lowered via a hydraulic cylinder (19). Two hydraulic cylinders (1, 2) whose stroke dead centres are offset at an angle to one another serve to swivel the slewing platform (21). The angular position of the slewing platform (21) is detected via two plate cams (16, 17) and via an angle transmitter (23). In the slewing-range end positions (E1, E2), the plate cams (16, 17) reduce the flow through choke valves (12, 13) which are connected in the rod-side hydraulic lines (10, 11) of the cylinders (1, 2). The output signal from the angle transmitter (23) is converted in a limit-value electronics unit (24) and controls the hydraulic valves in a reversing-valve block (18) as well as in the main slide (3). This enables a uniform progression of the slewing moment and the angular velocity of the slewing platform (21) as well as a safe approach to the slewing-range end positions (E1, E2) to be achieved. <IMAGE>

Granted: 1989-11-23
Abstract: A sewing machine is designed so that the feed dog executes, as desired, either rectangular movements or horizontal sliding movements only. The sewing machine has a lower feed dog to which adjustable horizontal sliding movements are imparted by a drive cam via a stitching actuator and vertical lifting movements are imparted by a drive cam via a pivoting lifting shaft with a lifting cam. A releasable coupling (34-39) is arranged between the lifting shaft (29) and its drive cam (25). The sewing machine can be used both for normal sewing operations, in which the lower feed dog executes a rectangular movement, and for hemming operations in which it may execute horizontal sliding movements only.

Granted: 1992-04-09
Abstract: The invention relates to a process and an installation for depositing a diamond layer on a workpiece, for example a drawing die or a punch tool, in which a reactive, plasma-aided coating process is used. According to the invention, the plasma is generated by means of a direct-voltage arc discharge, a current of charged particles additionally being introduced into the discharge path; the workpiece to be coated is placed, according to the invention, in the discharge path. The design according to the invention makes it possible to use a relatively long discharge path, with the result that even large surface areas can be coated; the coating takes place in an area of very high plasma homogeneity and density. The invention provides a process which can be cheaply and reliably controlled and which is suitable even for large-area coatings.

Granted: 1992-11-12
Abstract: In order to record vehicle driving data with a higher resolution, in particular at the beginning of an accident, a memory control is disclosed which permanently scans with two different frequencies (f1 and f2) the analog measurement signals (1) detected by a measurement sensor of a data processing device suitable for a vehicle, once the analog signals have been digitalized, and which stores them in two parallel ring memories (22 and 23) clocked at the f1 and f2 frequencies. When an accident is recognized, the ring memory (22) clocked at the slower frequency is stopped once a determined follow-up time (9) has elapsed, and at the same time data storage in the ring memory (23) clocked at the higher frequency is immediately interrupted and transferred to another semiconductor memory (26) in order to maintain high-frequency data recording for the duration of the accident phase.

Title: Arrangement for connecting a stopper-rod for a metallurgical vessel to its lifting device, and stopper-rod suitable for the arrangement, and method for producing the arrangement
IPC: B22D41/18
Filed: 1993-07-23
Granted: 1994-08-25
Abstract: The arrangement (100) comprises a carrier (10) on whose one end a lifting device engages and which projects with its other end into an inner longitudinal recess (8) in a stopper-rod (2). The stopper-rod (2) has an installation space (17) which widens the longitudinal recess (8) laterally and whose downwardly adjoining side walls merge in a curve or conically into the longitudinal recess (8). The carrier (10) comprises at least one blocking member (14, 24) which can be displaced by an auxiliary assembly bar (36), which can be introduced into the longitudinal recess (8), such that said blocking member projects out of the cross-section of the carrier (10) into the installation space (17). To release the connection, after releasing a nut (7) which is supported against the end face (11), only the stopper-rod (2) has to be displaced further upwards on the carrier (10), as a result of which the blocking members (14, 24) are automatically displaced back into the cross-section of the carrier (10) and the stopper-rod (2) can be withdrawn downwards from the carrier (10). It is therefore possible to make the installation space (17) in reusable pressing-in sleeves (29) which are also pressed in during the isostatic pressing of the ceramic stopper-rod material. <IMAGE>

Granted: 2003-07-01
Abstract: The creation of a micro-climate around a growing organism in a greenhouse cultivation provides absolute energy economy and positive cultivation manipulation forth increase of production, flower formation or plant morphology. The micro-climate has a radiation range of approximately 1 m and the process is based on the measurement and regulation of relative air humidity, temperature of leaves, sap flow measurement, growth point measurement, root temperature, stem diameter development, etc. The control of the micro-climate takes place on the basis of the measured parameters and possible growth models still to develop at the level of the micro-climate. The invention makes use of the principle of an inverted temperature gradient. An adjustment is made of a buffering of the heat in the growing organism, so as to prevent radiation to the colder space in the upper part of the greenhouse as much as possible. The buffering consists of placing the plants as close together as possible, combined with the use of insulating materials placed around the plant containers.
