Title: Workpiece contour measurement for surface grinder - using measuring mode with speed monitoring of slowly rotating tool to determine contact points
Inventor: HANDSCHICK BERT DIPL ING
IPC: B24B49/16
Filed: 1991-01-14
Abstract: The grinding tool (4) is rotated slowly and its speed monitored.

The tool is held on a multi-axle support, incorporating rotational and longitudinal degrees of freedom. The controlled contacting, with rapid stopping of the tool, prevents grinding damage to the surface. ADVANTAGE - Automatic surface profiling using grinding tool without additional measuring appts. Minimum damage to workpiece.

IPC: G01N33/32
Filed: 1991-04-26
Abstract: The method of investigating the coalescence process of a polygraphic material in a 2 or 3 phase system involves using the drop investigation method and the application of the digital image measurement technique. A vertically positioned drop of defined vol. is successively forced against a solid, flat surface with a defined foce. After coalescence the drop is removed from the surface. The drop removal phase is measured using digital image analysis. Edge angles of the drop are determined which are formed when the substrate is moistened under dyanmic conditions. USE - The technologically relevant records of the dynamic coalescence processes of polygraphic materials are derived from images of the interactions at the boundaries of 2 or 3 phase system.

Title: Process for burning carbonaceous materials - in spiral-stream firing appts. comprising combustion chamber with start=up burner and cooling chamber
Inventor: MOHR HORST
IPC: F23C3/00
Filed: 1991-04-30
Abstract: In burning carbonaceous materials having a specific grain size in a spiral stream, the combustion is initially started allothermically during a relatively short time interval, esp. using ignition firing. The material introduced as material-conveying air mixt. to be burned and combustion air are tangentially introduced into the combustion chamber, and after the start-up time interval further combustion is carried out independently at the required temp.. The novelty is that at least the independent combustion is carried out at more than 1200 deg. C independent of throughput (kg/hr) of the material to be burned. A spiral-stream firing appts. for carrying out the process is also claimed. USE/ADVANTAGE - The appts. can be used to burn filter dust produced from the carbonisation of Al-waste contg. amorphous C and finely ground elementary Al charged with dioxin and furan, and also used to burn finely ground Ca-cpds. and ground coal and coke originating from filter appts. of e.g. waste disposal plants.

Title: Pallet-handling unit and layout for plastic injection moulding machine
Inventor: HEHL KARL
IPC: B29C31/00
Filed: 1991-06-19
Abstract: Pallet-handling unit and arrangement are for plastics injection moulding machine. A usual parts-removal device transfers mouldings from the opened mould to a filling station (Fs) at the clamping end of the moulding machine. The pallets are individually supported in support plate which slides on guides in a transport unit. At least two units are carried on forks cantilevered from a carriage. This carriage moves vertically on a frame attached to the rear or end of the moulding machine, forming together a pallet tower. A pallet on its support plate is withdrawn horizontally from the tower onto guides aligned in the filling position (Fs). During the filling process, the carriage may be raised or lowered to remove filled units or exchange empty units. When filling is complete, the pallet may be returned to the same position in the transport unit that is left. The carriage is then moved to a position for the next empty pallet to be transferred to the filling position (Fs).

Title: Automatic regulating system for injection mould closure pressure - has controller which regulates curve of mould closure pressure against time according to corresponding curve of internal mould pressure
Inventor: ROEPER JUERGEN
IPC: B29C45/76
Filed: 1992-01-07
Abstract: A system regulates the pressure to close injection moulds where the closure force is transmitted via a moving mould clamping plates to the mould tool. The system has gauges positioned where their readings enable the internal mould and closing pressures to be obtd. over the time concerned; an electronic controller evaluates and stores the readings, it depicts these pressures against time for each operating cycle, and regulates the closure pressure against time during the cycles as a function of the course of the internal mould pressure against time; the drive system has correction devices which convert the signals from the electronic controller into adjustments to regulate the course of the closure pressure against time for each cycle. ADVANTAGE - The closure pressure is regulated at each point of the operating cycle and according to the needs of the moment. This contrasts with normal system which do not take into account that the max. internal mould presusre is usually present when the mould is full, whereas the max. closure pressure is usually applied at the start of the moulding cycle.

Patent DE-4203674-A1 (DE)
Inventor: BRANDES MANFRED DR ING
IPC: H04L25/52
Filed: 1992-02-08
Abstract: According to the object, the linear distortion due to inadequate transmission of low-frequency spectral components and superimposed low-frequency interference sources occurring during the transmission of digital signals is to be eliminated. Networks as used in quantised feedback, the frequency response and variation with time of which must be matched to one another, are not to be used. The method according to the invention has the effect that from the bivalent digital signal a trivalent signal is produced by clamping the voltage for a short time to a reference voltage UO at the detection point under control by the bit clock. The value of the digitial signal is determined by a logic operation from the voltage values of successive bit periods and is provided as regenerated signal at the predetermined bit clock rate. The method provides for regenerating even multi-valent signals. It is preferably used in PCM engineering. <IMAGE>

Title: Sliver delivery textile machine for card cans fibrous material supply - comprises changeover system by trolley patrolling stand of card cans at machine, for stacking in min space with access
Inventor: SCHUMANN JOACHIM
IPC: D01H9/18
Filed: 1992-03-24
Abstract: The machinery has stands to hold the cans. The full and empty cans trasnporter exchanges with those on the stands. The front row of cans on the stand are moved apart so a mechanism on the trolley, which runs parallel to the machine, may intersect to change a can on a fixed stand near to the machine. The machine (S) pref. has a series of working positions, which require a supply of fibre in the form of a roving or sliver. This is held in bulk in the card cans (Ka-Kz) and (ra - ry), each supplying to one working position. The row of cans (ka - kz) near the machine are pref. held in a fixed position, and the front row (ra - ry) are supported on a base of rollers (R). This may alloy the can on the rollers to move apart sufficiently for a can (5) to be brought forward and replaced. The can changeover is effected by a trolley, which runs on a rail at the front of the cans. There is a mechanism with two-part drive, to extend and connect to the base roller ends (24), to form a drive in alternate pairs, with spring clutches so a drive may be given to the right or to the left. Sensors (47,48) are used to determine the extent of the drive. The rollers have a friction surface to engage the base of the cans. USE - Used to stack card cans in the smallest possible space and gives access at time of can changeover, with the least amt. of movement and disruption to continuous running.

The deformations of the reference body are calibrated in units of change of length of the test body.  The reference body is of material with negligible thermal expansion coefficient. ADVANTAGE - Simple, easily operated arrangement yielding sufficient accuracy.
