Title: An automatic washing machine
IPC: D06F58/38
Filed: 1980-11-27
Abstract: In combined automatic laundering and drying machines, there is a problem in combining the measuring devices for the temperature of the washing liquid and of the laundered articles as well as for the moisture of the laundered articles into an integrated measuring system without replacing the hitherto conventional measuring organs by completely novel ones. Beyond that, it is desired completely to avoid the drying operation time control hitherto usual in such machines. In a preferred embodiment of the invention, each measurement sensor of each group of measurement sensors (11-2, 21-2, 31-1, 31-2) is associated with a first input of a respective comparator (1 to 3) which is arranged to produce output signals with a step-function characteristic and a second input of which is supplied with a respective one of fixed or adjustable reference values (10, 20, 30), the output of the comparators (1 to 3) being connected through a mixer stage (5) to a switching device (6, 61, 65) for the heating devices (62, 66). <IMAGE>

Title: Semiconductor memory cell array
IPC: H01L27/108
Filed: 1980-12-12
Abstract: A semiconductor memory cell array has bit lines 11, 13, 14, 16, 17, 19 diffused in a semiconductor body 10 of opposite conductivity type and overlaid conductive word lines 21. The cells, which comprise diffused regions 101-106 of the same conductivity type as the bit lines are arranged in pairs (e.g. 101, 102) between bit lines 11, 13. A word line overlies gate regions between bit lines and cell regions (e.g. between 11 and 101 and between 13 and 102) to form an IGFET structure. The cell regions of each pair are contiguous with an auxiliary region 12, 15, 18 in the body 10 and have the same conductivity type as the body 10 but higher conductivity, to enhance the capacitance of the cells. The array is contactless, i.e., does not involve connections to the individual cells or pairs of cells. A self-aligned fabrication process is described. <IMAGE>

Title: Injection frequency locked laser apparatus
IPC: H01S3/23
Filed: 1981-04-10
Abstract: In a very high power, stable frequency TEA pulsed laser a conventional CW laser tube 30 is positioned in a resonant cavity 10 with the high power TEA laser 40. The high power output pulses are frequency locked to the CW laser by adjusting a mirror 20 to change the optical length of the resonant cavity in response to the frequency of a portion of the output signal from the CW laser. The mirror 20 is dithered at 1kHz with TEA laser off and the CW laser on. A 2kHz dither is superimposed on the output signal because of the output characteristic. At the peak of the characteristic only a fundamental 2kHz signal is present. This is detected by control circuits 80 which otherwise generate an error signal to reposition mirror 20. When the error vanishes the dither is switched off and the mirror 20 is held is place. Arrangement is used in target tracking where reflected laser beam is projected onto a detector together with a local laser beam to produce a heterodyne signal. Local laser frequency stabilisation is described.

Patent GB-2116334-A (GB)
Title: Eye follower
Inventor: HOBBS KEITH CHRISTOPHER
IPC: G06F3/01
Filed: 1982-03-04
Abstract: Patent No. 1581018 describes a so-called eye follower, in which a TV camera views an operator's eye. The image of that eye is analysed and the result of the analysis indicates the direction in which the operator is looking. This result generates an output which can be used to operate a peripheral device. This is usable to enable a disabled person to control operations to be performed. In such a system some inaccuracies may occur due to minor head movements or an initial misalignment. To overcome this, when the user's eye (10) is viewing a screen (11) bearing indications of the desired control functions, a closed loop is set up. For this, the output of the eye follower (13) is applied to the screen (11) so that the user can see if it is correct. If it is not, he adjusts, via a manual input (14) or a calibration subroutine, the output of the eye follower until the latter coincides with the intended viewing point. The control function output from the eye follower is only effective when this adjustment - or confirmation - of the setting occurs. <IMAGE>

Abstract: The invention relates to a process for the preparation of the propagating matter (seedling) of foxglove (Digitalis lanata Ehrh.) under vegetative micropropagation in a tissue culture, by subjecting the seeds or the shoot apices of open-air plants to superficial sterilization. According to the process of the invention   a) a sterile plant with some, preferably 2-3, leaves is produced from the sterile seed or the sterile shoot apex of open-air plant on a known culture medium, b) the sterile plant with some, preferably 2-3, leaves is optionally derooted and then trans-inoculated (passaged) onto a propagating culture medium containing auxin(s), cytokinin(s) and optionally gibberellic acid, the plant is propagated there until a stage of 20-40 side shoots is reached, then the plant is divided into leaf bows of preferably 2-3 leaves each and, if desired, propagation is repeated until the desired number of plants is obtained, c) the sterile leaf bows with preferably 2-3 leaves are transplanted onto a rooting culture medium containing an auxin or an auxin and a cytokinin, and rooting is induced until roots, 4-8 mm in length, are developed, d) the plants with roots 4-8 mm in length are rooted on a culture medium free of auxin(s) and cytokinin(s) until a root length of 4-6 cm is reached, and e) if desired, the resulting propagating matter (seedling) is adapted to open-air conditions.   In this way a homogeneous, genetically stable population is obtained.
