Title: Turning frame for dressing window frame welds - has cylinders with arms and end rollers to rotate bars in their plane
Inventor: STUERTZ KARL-HEINZ
IPC: B29C37/04
Filed: 1990-03-01
Abstract: Equipment turns a frame, and a metal or plastic welded frame in particular, when it is positioned at a machine to dress its welds. The equipment has a horizontal guide with side strips and locking members to hold the frame in position for dressing on a working plate. This plate and the strips are arranged verically or nearly so; the guide has two stop bars with a gap between; these bars can turn through an angle of at least 45 deg. up from the horizontal position by means of one common tilting device. The example shown turns a window frame (1) which is held against strips (4,5) in a nearly vertical plane for its corner welds to be dressed. These strips (4,5) are horizontal in one position but turn about the axis (6) through max. 60 deg. on guide rollers (7) at the end of tilting arms (8) which are (here) held on a fixed shaft (9). An arm (10) is swivelled by a cylinder (11). The strips (4,5) can be tilted separately when the frame (1) is in position both strips (4,5) are tilted to the position shown. The frame is taken to position on the guides (2) ADVANTAGE - The layout turns vertical/nearly: vertical frames very easily so that the corners of the frames can be dressed in succession.

Title: Hydrolysing starch content in jellied confectionery - in second of two successive heat exchangers under slightly increased pressure and temp.
Inventor: LIESER ALFRED DIPL ING
IPC: A23L1/09
Filed: 1990-03-27
Abstract: In the mfr. of jellied confectionery, e.g. crystallised fruits or wine-gums, a slurry of sugar crystals, glucose syrup, starch and water is continously fed through a first heat exchanger under sufficient temp. and pressure to dissolve the sugar without affecting the starch. The warmed mixt. then passes through a second heat exchanger where slightly increased pressure and temp. rapidly cause swelling and hydrolysis of the starch particles. Correct pressure levels for both exchangers are maintained by a regulator following the second exchanger. ADVANTAGE - With only a few degrees higher temp. needed in the second exchanger, dimensions are kept small. An increased range of starches can be used, with only as much water as required in the final prod.

Title: Shuttle box positioning - has AC servo motor to move shuttle box under loom control with feedback for fine adjustment
Inventor: JOHANSSON HANS
IPC: D03D43/04
Filed: 1990-09-28
Abstract: The adjustment assembly for the shuttle boxes, to align the shuttle layers for the loom, has an AC servo motor (7) controlled by signals (il) from the automatic loom control (6). The control (6) generates a command signal (il) for the positioning of the shuttle box between the available layers by rotating the AC servo motor (7) assisted by a transmitter (7a) at the motor with a feedback signal (i2) to give an accurate  adjustment to the command signal value. The rotation of the servo motor is converted into a linear movement of the shuttle box. The drive transmission to the shuttle box is a threaded spindle (9a) and a fixed nut (9b) which is rotated by the motor to move the spindle up an down. The threaded spindle has rotating -screws at the ends to be turned by a toothed belt (8a) or a shaft coupling. The threaded spindle/screws have a fixed cogwheel or shaft coupling section. The nut (9b) is connected to the under side of the shuttle box through an operating unit (9c) which follows the movement of the nut (9b). The transmission can also be a rod to one side with a guide, connected to a toothed belt from the motor, together with a component which controls the guide at the same time as it directs the toothed belt and shuttle box.  The toothed belt passes round two or more cogwheels,   where the first cog is coupled to the motor shaft. The support for the shuttle box, moved by the spindle, shows its position through a number of sensors (12,13,14,15) arranged to one side. ADVANTAGE - The mechanism gives an accurate positioning for shuttle boxes which operate for long periods and at high speeds and frequencies in the automatic loom.

Title: Aligning and clamping mandrel for gear blanks, etc. - has expanding collet to centre and clamp blank, with locking spring loaded rods for face support
Inventor: ZIMMERMANN HEINRICH
IPC: B23B31/30
Filed: 1990-10-17
Abstract: The mandrel (2) has a reduced dia. (8) projecting through a surrounding and attached work table (3). The gear blank (4) slides over a collet (11) and rests on a two-part cardan ring (16). A drawbar (6) has an end collar (14) which can push downwards on a plunger (13) to hydraulically expand the collet, thereby centring and clamping the gear blank. Any irregularity or out-of-squareness the face of the blank is taken up by the cardan ring. Just below the cardan ring surface are the ends of spring-loaded rods (17). Downward movement of the drawbar releases a catch (18) and allows the rods to move up against the underside of the blank. Continued movement of the drawbar actuates a second plunger (26) to lock the rods in position. The blank is now accurately centred square to the bore and adequately supported by an operation such as tooth grinding. ADVANTAGE - An additional operation to grind a face of the gear blank square to the bore can be avoided.

Filed: 1991-12-21
Abstract: A device for measuring a variable, for example the deceleration/acceleration of a motor vehicle, has at least one sensor and an amplifier of variable signal gain, the gain being varied in such a way that in a specific, particularly critical range of the variable an increased measurement sensitivity is obtained. For this purpose, gain is varied as a function of the variable to be measured. The gain may be a quadratic or logarithmic function of the value of the variable, so as to provide maximum sensitivity at low signal levels, and the device may be used to trigger a seatbelt tensioner or airbag.
