Title: Method for correcting the trajectory (flight path) of a missile, and a missile for carrying out this method
Inventor: FLECK VOLKER DIPL ING
IPC: F42B10/66
Filed: 1988-01-28
Abstract: In order to correct the trajectory of a fin-stabilised missile, this missile is caused to oscillate intrinsically, according to the invention, by means of a control pulse. This intrinsic oscillation is either completely cancelled out again by means of a second control pulse, or a second intrinsic oscillation is induced which is superimposed on the first intrinsic oscillation in such a manner that the missile is bent in a predetermined manner for at least a short time. This bending is cancelled out again by two specific control pulses after completion of the correction process, so that there is no residual oscillation whatsoever. In this case it is not only possible to produce major changes in the trajectory, suddenly, using very simple means, but, once the control process has been completed, the trajectory and the missile longitudinal axis always point in the same direction, as a result of which the complexity required to control the projectile can be considerably reduced.

Title: Device for controlling an automatic motor vehicle clutch
Inventor: PETZOLD RAINER
IPC: B60W10/02
Filed: 1988-03-18
Abstract: Device for controlling an automatic motor vehicle clutch (1) which is arranged between a drive engine (2) and a transmission (3). This clutch acts predominantly as a starting clutch and the engine torque (TM) and the engine speeds in front of and behind the clutch (nM, nGE) are detected or determined. A control device (5) converts an electric signal originating from an electronic control device (6) into a control variable for an adjustment device (4) for opening or closing the clutch, unacceptable oscillations (S) in the drive train between engine (2), clutch (1) and transmission (3) are detected from the frequency (f) and the amplitude (R) of the initial speed of revolution (nGE) of the engine (nM) and/or of the transmission and eliminated by defined opening of the clutch (1). This opening takes place up to a travel mark (WM2) which is derived from a characteristic curve (K) stored in the electronic control device (6). For this purpose, during each starting-up process in the deflection point (UP) of the speed of revolution of the engine (nM) the associated engine torques (TM) and travel marks (WM) of the clutch travel are stored and the characteristic curve (K) calculated and constantly renewed by ongoing measurements and improved as a result of the frequency of the measurements. In a second design, the clutch can also be closed only as far as this travel mark (WM) at which the engine torque (TM) and the torque at the transmission input shaft (TGE) are identical. <IMAGE>

Title: Mechanical power transmission for a pneumatic power cylinder
Inventor: KLEES HEINRICH
IPC: F15B15/02
Filed: 1988-07-29
Abstract: A mechanical power transmission for a pneumatic power cylinder essentially consists of an elongated housing (10) which can be supported against the power cylinder (14) and has a longitudinal tooth system (32) in the interior. A hollow supporting part (36) displaceable in the housing (10) has a locking member (40), movable into engagement with the longitudinal tooth system (32), for axially securing the supporting part (36) to the housing (10). An elongated control element (50) passing through the supporting part (36) can be secured with its rear end to the piston rod (58) of the power cylinder. A spring arrangement (62) produces a frictional connection between the supporting part (36) and the control element (50). When the frictional connection relaxes, first control means (64) arranged on the control element (50) put the locking member (40) into engagement with the longitudinal tooth system (32). An output element (30) is displaceable in the front part of the housing (10). A toggle-lever device (96) is arranged between the supporting part (36) and the output part (30). Upon further relaxing of the frictional connection after the engagement of the locking member (40), the toggle-lever device (96) can be acted upon in the extension direction by second control means (98) arranged on the control element (50). Such a power transmission delivers a high transmission ratio, and at the same time overloading and destruction are effectively prevented. <IMAGE>

Title: Process and apparatus for the preparation of chlorinated chloroformates
Inventor: MOGYORODI FERENC DR
IPC: B01D3/14
Filed: 1988-08-04
Abstract: The invention relates to a process for the preparation of monochloromethyl chloroformate and trichloromethyl chloroformate by photochlorination of methyl chloroformate. According to the process, in a first step at 60-70@C chlorination is carried out until the ester is reacted to at most 50%, then the reaction mixture is separated by rectification and the unreacted methyl chloroformate is fed back into the reactor. The molar ratio in the reactor between ester and chlorine gas is between 3:1 and 2:1. The monochloromethyl chloroformate obtained during the rectification as a bottom product is either drawn off as a final product or completely or partially led into a further photochlorination reactor in which the molar ratio between monochloromethyl chloroformate and chlorine gas is 1:2-1:3 and the temperature 90-110@C. The reaction product is separated by rectification and the head product is fed back into the second reactor, while the trichloromethyl chloroformate formed as the bottom product is led off as a final product. The invention further relates to a suitable apparatus for carrying out the process continuously. <IMAGE>

Title: Method and means for cleaning a seal for a rod which can be moved in a fitting casing mainly in an axial direction
Inventor: MIETH HANS OTTO DIPL ING
IPC: B08B9/032
Filed: 1988-12-08
Abstract: The invention relates to a method and means for cleaning a seal for a rod which is movable in a fitting casing mainly in an axial direction as specified in the preamble to Claim 1. A seal of this type ensures that all its regions are permeated by cleaning agents with the same degree of reliability and independently of the position and that the seal is loaded with cleaning agents virtually without pressure. This is achieved via process technology among other means, by directly feeding the fresh cleaning agent to the inside sub-space (3a) with a tangential speed component in such a way that the speed at which the cleaning agent flows on the path between an inlet and outlet aperture (3e and 3f respectively) of the sub-spaces decreases and that the energy inherent in the cleaning agent as it enters the interior sub-space (3a) is essentially only present in the form of kinetic energy (Figure). <IMAGE>

IPC: C12C1/12
Filed: 1989-06-06
Abstract: An installation for producing malt from cereals comprises a rotary kiln, a chamber located below the rotary kiln and a chamber located above the rotary kiln. The kiln and the two chambers are coaxial. A partitioning system is arranged inside the rotary kiln. The installation is improved by arranging fixed radial partitions in the rotary kiln which divide it into germination regions, an air-drying region and a kiln-drying region. Sealing elements are associated with the partitions in the rotary kiln and/or the partitions in the upper chamber. The rotary kiln is set in motion periodically so that the partitions in the rotary kiln are aligned with the partitions in the lower chamber and with the partitions in the upper chamber and co-operate with the latter by means of the sealing elements. The inlet spaces in the lower chamber, the regions of the rotary kiln and the oulet spaces of the upper chamber are therefore designed to form separate channels for the flow of germination air, the drying air and the kiln-drying air through the installation.

Inventor: SIEGEL HEINZ ING GRAD
IPC: B60T8/175
Filed: 1989-11-03
Abstract: The hydraulic brake installation (10) of the invention is fitted with a device (70) for limiting drive-generated slip of the driven wheels (30 and 32). It has pressurizing units (72, 84) acted on by hydraulic fluid to generate pressure in the associated wheel brakes (26 and 28, respectively). The increase in pressure in the brake (e.g. 26) is slowed by a switchable throttle (82) fitted in the hydraulic-fluid supply line to the pressurizing unit (72). The throttle becomes effective at the brake pressure reached when the brake liner lies against the the disc or drum of the brake (26). This ensures that the brake (26) acts rapidly, independently of the hydraulic-fluid capacity of the brake, and gives a brake pressure which increases slowly and remains stable as it changes.
