Patent DE-2161306-B2 (DE)
Title: Valve rotating mechanism for IC engine - has split circular spring to dispense with need for ball cage
IPC: F01L1/32
Filed: 1971-12-10
Abstract: A fixed ring (4) has tapered slots (6) holding balls (5). A circular leaf spring resting on the balls presses on a cap which forms the seat of the valve spring. Each slot (6) is curved so that it has a smaller radius at is deeper end than at its shallower end. A split circular spring (7) surrounds the valve shaft and rests on the inner sides of the balls (5). As the valve is depressed the cap and leaf spring exert a force on the balls which moves them to rotate the cap. When the valve closes the split spring (7) returns the balls to their initial position.

Title: Test gear for peripheral unit using AM signals - has modulator for conversion to frequency or phase modulation and has store for feed to demodulator
IPC: G01R31/30
Filed: 1972-05-12
Abstract: The peripheral instrument test circuit, supplies the instrument with an amplitude modulated signal. The peripheral unit is held in the operating condition. The functions are monitored as the signals to the peripheral instrument. Any fault will be located and rectified immediately. The amplitude modulated signals are fed to a modulator (MOD) which converts them into frequency or phase modulated signals. These signals are stored and then transmitted to a demodulator as necessary (DEM 1, 2, 3). The reaction of the peripheral is immediately evaluated. The modulated signals may also be stored in a memory.

Title: A bale wrapping machine
Inventor: COX ALFRED ANTHONY
IPC: A01F25/00
Filed: 1994-11-15
Abstract: The invention concerns machines for wrapping large bales 24 of fodder, particularly, square or rectangular bales. The machine is of the kind comprising a turntable 6 which is rotatable about a vertical axis and which rotates the bale about the vertical axis, conveying means to turn the bale about a horizontal axis, and means 16 for continuously supplying a strip 17 of wrapping mateial to the bale as the bale is simultaneously turned through the two axes, to wrap the wrapping mateiral around the bale. The conveying means is in the form of an endless conveyor belt 12 suspended above the turntable and having a substantial sag which defines a cradle to receive the bale, and which assumes a substantially u-shape or v-shape when a bale is placed on the belt. The belt travels about four rollers comprising two lower rollers 210, 211 disposed transversely of the turntable and located forwardly and rearwardly of the turntable respectively, and two upper rollers 212, 213 spaced above and parallel to the lower rollers. There is an adjusting roller located between each one of the lower rollers and the corresponding upper roller, about which the belt also travels. Sliding bearings are provided to displace the adjusting rollers towards or away from each other to increase or decrease the sag in the belt, and for displacing the adjusting rollers out of parallel to control tracking of the conveyor belt. Pivoting side restraining roller assemblies are also provided.

Title: A mock-linking apparatus and process
Inventor: CULLEN JOHN CHRISTOPHER
IPC: D05B35/06
Filed: 1995-06-07
Abstract: A mock-linking apparatus is used in a process whereby the trim to be stitched to the garment unfinished edge has a double row of single bed stitching adjacent one edge for improved simulation of linking loops. The edge of the trim is folded over and then the whole trim is folded, manipulated and presented by a single-piece guide with a presentation section (28) inclined to the feed direction at an angle in the range or 100{ to 110{. A stitching head has a deflector (32) engaging the lower section of the folded trim and a foot (36) configured to accommodate the upper side of the trim with its folded under edge. Drive is provided by a separate pair of drive rollers (4, 42) mounted downstream of the stitching head whereby there is a clear path for the layers of fabric through the stitching head free from drive dogs. The deflector (32) can be displaced by a piston (35) to remove the lower trim section from the stitching head. The upper trim section is guided so as to overlap the garment to a lesser extent than the lower section.

Abstract: A Grob cold-rolling machine, which is known per se, can be taken as a basis, the said machine, as is known, having rolling-head carriers (26) which can be adjusted towards and away from the workpiece (1, 11, 111) and contain rolling heads (27) which can be driven in rotation. Mounted in the rolling heads (27) are impact rollers (28) which, as the rolling heads (27) revolve, revolve on a circular path (280) and can perform individual rolling operations on a workpiece situated on a mandrel (3). In addition, an undriven pressure roller (29) with the ability to rotate freely is mounted on each of the rolling-head carriers (26) outside the circular path (280) of the impact rollers (28), being mounted on a roller axis (290) parallel to or obliquely inclined with respect to the mandrel axis (31).

Abstract: A method and apparatus for addressing faster responding liquid crystal panels (LCDs) so that video rate, high information content LCDs having time constants on the order of 50ms or less, are perceived as having brighter bright states and darker dark states by limiting peak voltage levels across the pixels. A first set of LCD electrodes are continuously driven with signals each comprising a train of pulses that: are periodic in time; have a common period T; are independent of the information to be displayed; and are preferably orthonormal. A plurality of column signals are generated from the collective information state of the pixels defined by the overlap with a second electrode pattern. Each column signal is proportional to the sum obtained by considering each pixel in the column and adding the voltage of that pixel's row at time t to the sum if the pixel is to be "off" and subtracting the voltage of that pixel's row at time t from the sum if the pixel is to be "on". If the row signals only switch between two voltage levels, the sum may be represented as the sum of the exclusive-or (XOR) products of the logic level of the amplitude of each row signal times the logic level of the information state of the pixel corresponding to that row. Hardware implementation comprises an external video source, a controller that receives and formats video data and timing information, a storage means for storing display data, a row signal generator, a column signal generator, and at least one LCD panel. Alternative embodiments provide gray scale shading and circuits to reduce the magnitude of the column signals, as well as the number of column voltage levels required to generate a displayed image. <IMAGE>
