Patent GB-2048314-A (GB)
Title: Improvements In and Relating To Electrical Machines
IPC: D06F37/42
Filed: 1979-05-14
Abstract: A control system of a washing machine or spin dryer is described, in which operation of the motor 1 driving the washing machine or dryer drum is controlled by a microprocessor 4. To ensure that the door of the drum can not be opened when the motor 1 is operating, a changeover switch 13 is provided, through which either the motor 1 is energized (to rotate the drum) or a door locking means e.g. a solenoid 11, is energized (to permit the door to be opened) but not both: if the locking means 11 is not energized the door can not be opened. Operation of the changeover switch 13 is effected by a bimetallic element carrying a movable contact 13c heated, under the control of the microprocessor 4, when the motor is operating. When the motor is de-energized, the heat is removed and the bimetallic element cools down: the locking means 11 is not energized until the bimetallic element has cooled and the time delay thus introduced ensures that the door can not be opened until the drum has slowed down. <IMAGE>

Title: Liquid crystal mixture
IPC: C09B1/20
Filed: 1979-12-19
Abstract: In a liquid crystal mixture which is intended for use in displays that have no polarizers and which is composed of a dye as a guest phase embedded in a host phase mixture consisting of a nematic liquid crystal with an optically active dopant, at least part of the dye is an anthraquinone dye having the general formula:   <IMAGE> in which R<2>, R<3>, and R<4> are the same or are different and each is a hydrogen atom or a hydroxyl, amino or short- chain N-monoalkylamino group; Y and Z are the same or are different and each is a halogen atom, an amino or hydroxyl group or an alkyl, alkoxy or alkylamino groups containing from 1 to 16 carbon atoms; and m and n are each 0, 1, or 2. These dyes are commercially available and their dichroic ratios are nearly as good as the best anthraquinone dyes proposed for the cholesteric guest-host effect, which must be custom prepared. Furthermore, the dyes used have an adequate solubility in the host phase and are especially stable to the UV component found in natural daylight.
Patent GB-2045243-A (GB)
Title: Producing codeine from cell cultures
IPC: C12P17/18
Filed: 1980-02-25
Abstract: The production of codeine has been achieved from modified cell cultures derived from the plants Papaver somniferum L. or Papaver setigerum DC. The cell cultures have been constrained to produce cytodifferentiated polyploid cells which are considerably larger than the normal non-differentiated cells. In the presence of these polyploid cells the production of codeine is realized.

Title: Measuring surface roughness
Inventor: MARSHALL RALPH JOHN
IPC: G01B11/02
Filed: 1981-09-25
Abstract: A housing 1 on an adjustable support 2 incorporates a lighting source 4 for projecting a light beam at an angle onto a rough surface 3, e.g. skin. Reflections from the surface 3 are observed by a video camera 5 whose output is led to a control unit 6 incorporating a microprocessor for analysing the signals and displaying a trace of the surface texture on a screen 7. A roughness value is calculated by analysing the light density variation along a line portion of the surface and comparing this with a standard value. The reflections may instead be photographed and light transmitted through the negative along the line portion. A graphical trace of the light density may be made and the roughness value taken as the trace length or calculated from the mean peak to peak frequency or amplitude, the integral of the area to both sides of the mean or from a Fourrier analysis. <IMAGE>
