Title: Bistable trigger circuit
IPC: H03K3/315
Filed: 1961-12-06
Abstract: 990,682. Tunnel diode bi-stable circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 6,1961 [Dec. 23, 1960], No. 43647/61. Heading H3T. A bi-stable circuit of the type comprising two negative resistance semi-conductor devices connected in series so that one or other is in a high voltage state has control means to move the operating point of one of the devices in each state very close to its negative resistance region. Fig. 1 shows two tunnel diodes 20, 22 connected in series resistor 26 to a source 24 so that one or other is in the high voltage state. Assuming 22 is initially in the low voltage state, the potential applied from junction point 50 to the cross-coupled transistor circuit 54, 70 is such as to maintain transistor 54 cutoff or lightly conducting and transistor 70 conducting such that the current passing through lead 52 moves the operating point of diode 22 very close to its peak point. A positive pulse at terminal 30 switches diode 22 to the high voltage state and 20 in the low voltage state. This causes the conduction conditions of the two transistors to reverse and to move the characteristic of diode 20 to a new operating point very close to its valley point.

Title: Control of the filling level of sliver reservoirs in the textile industry
IPC: B65H51/20
Filed: 1972-09-26
Abstract: 1400246 Sliver reservoirs; level control ZELLWEGER USTER LTD 26 Sept 1972 [22 Dec 1971] 44331/72 Heading D1F In a method of controlling the level of sliver in a reservoir, the level is detected by sensors at at least one level and the quantity of sliver delivered to the reservoir controlled on the basis of the detection, the method being characterised in that the level is rendered dependent on the size of the variations in the crosssection of the sliver. In the preferred embodiment, sliver 10 is delivered to the reservoir 20 from the drafting arrangement of a carding machine, and is taken from the reservoir for deposition in sliver cans. The rate of feed of the drafting arrangement is varied dependent on the detected thickness of the sliver and therefore the level of sliver in the reservoir is varied. Statistical methods are used to plot a frequency distribution curve for the filling level in the reservoir, and an acceptable minimum level, i.e. level at which 1% of levels is less than the minimum level, is determined and a sensor 23 is positioned in the reservoir to issue a signal on this minimum level being reached. When a signal is issued by the sensor 23, the feed to the card and the speed of drafting is compensated to increase the supply to the reservoir. In a further embodiment, when the level of sliver in the reservoir falls below the minimum value, a sag of 10" is produced, and to prevent the reserve sliver reaching breaking point, a further sensor is positioned to detect a safety level at which the drafting arrangement is acted upon to feed more sliver, even though of a reduced thickness. The removal of sliver from the reservoir may be controlled in response to the level detecting sensor signal. The or each sensor may be mechanical or electrical e.g. photocell or capacitive sensor.
