Patent GB-1597988-A (GB)
Title: Method and apparatus for obtaining water from moisture-containing air
IPC: A01G9/24
Filed: 1977-12-30
Abstract: The air is channelled into a cylindrical container (1), the wall of which, at least in that part exposed to solar radiation (5), consists of a material which is permeable to the rays (5) of the sun. The container (1) is partly embedded in the earth (11) and has, on the inner side of this part of the wall, a lower coating (4) consisting of heat-retaining and moisture-retaining material. That part of the container (1) exposed to solar radiation (5) has, on its inner side, an upper coating (4A) which promotes the condensation of the moisture in the air. In the case of air channelled in during the daytime, this air is heated up in the container (1), under the influence of solar radiation, as a result of which the moisture in the upper coating (4A) evaporates. In the case of air channelled in during the night, the moisture on the upper coating (4A) condenses and is either channelled away or is retained in the lower coating (4) and evaporates again during the daytime which follows. The moisture is channelled, as vapour, with the flowing air through a duct (13) to individual consumer points, e.g. the locations in the earth of individual plants, where some of the moisture condenses in each case because the earth temperature is lower than the temperature in the insulated area of the container (1). <IMAGE>

Title: Clothes washing and spin drying machines

Filed: 1972-11-27
Abstract: 1450679 Automatic control of electric motors in washing machines HOTPOINT Ltd 23 Nov 1973 [27 Nov 1972] 54658/72 Addition to 1266691 Headings G3N and G3R The control circuit for the washing and spin drying machine described and claimed in the parent Specification is modified by connecting the winding of the feedback tachometer in the series circuit supplying the base of the speed controlling transsistor with the reference voltage so that any fault in the winding causes the reference voltage to disappear and the motor to stop. In the control circuit shown the tachometer winding 39 is connected to the washing speed reference potential developed at point 38 and through resistors 40, 27 to the base of transistor 22 which adjusts the voltage applied to charge capacitor 20 thus altering the conductive period of thyristor 2 and the speed of motor 1. If the tachometer winding becomes disconnected or high resistance the voltage applied to transistor 22 is reduced and the motor stops. Protection of the motor is provided by the N.T.C. resistor 51 which responds to an over temperature by causing transistor 21 to conduct and earth the lose of transistor 22. Other features of the control system described are claimed in Specification 1450680.

Abstract: 552,927. Drawing apparatus for spinning-frames. CASABLANCAS HIGH DRAFT CO., Ltd., and NOGUERA, J. Oct. 27, 1941, No. 13814. [Class 120 (ii)] In drafting mechanism for textile fibres of the type using two endless bands for engaging and guiding the fibres being drawn, the belts are so arranged with respect to the front drawing rollers that the flattened strand is delivered by the belts to the rollers in a plane at right angles to the line of contact of the drawing rollers while the surfaces of the belts which are gripped between the beltdriving rollers are in a plane at right angles to the plane in which the strand passes from between the belts; by this means the belt-driving rollers can be disposed with their axes parallel to the axes of the front and back drawing rollers. As shown the belts 1, 2 are in contact with the fibres while passing from back guiding members 6 to front guiding members 5 while, in passing from the members 5 to the members 6, they pass between belt-driving rollers 3, 4, the strand leaving the back drawing rollers 7, 8 being taken in a plane at right angles to the line of contact of those rollers and being delivered to the front drawing rollers 9, 10 in a plane at right angles to the line of contact thereof. In a modification the belts are arranged to turn the fibres through 90 degrees while passing between them by the use of guiding members disposed with their axes at right angles to the axes of the belt-driving rollers. In a further modification the belts are guided between the first guiding members with driving rollers by middle guiding members and the driving rollers by middle through 90 degrees on leaving their driving rollers so that they travel in one and the same plane between the middle and front guiding members while in contact with the strand. Means may be provided for pressing the belts against each other or for diverting the belts from their straight pass in order to increase their grip on the strand and the pressing means may be resilient.

Abstract: 1,115,880. Flasher circuit. UNITEDCARR Inc. 16 Dec., 1966, No. 56450/66. Heading G4Q. A flasher circuit for a vehicle's directional indicators comprises a parallel combination of a first branch 1 including a high-resistance lamp L1 mounted within a lightproof enclosure E, a second branch including a photo resistance PR, also mounted in the enclosure E and connected in series with a slow to release relay RC and a third branch 3 including contacts C of the relay. The combination is connected in series with battery B to a direction indicator switch S controlling the energization of the left (L2, L3) or right (L4, L5) direction indicator lamps. Assume switch S is thrown to the left, the lamp L1 is energized causing the cell PR to be illuminated with the result that its resistance drops to a level which allows the relay to pick up and close its contacts C. This de-energizes lamp L1 and the relay and energizes the indicator lamps L2, L3 for a period determined by the relay's release time. On release of the relay the cycle repeats.

Abstract: 1,246,294. Semi-conductor devices. SONY CORP. 3 Dec., 1968 [12 Dec., 1967], No. 57279/68. Heading H1K. A monocrystalline semi-conductor substrate is prepared for the side-by-side deposition of mono- and poly-crystalline regions as follows. The surface is masked with a first layer and a seeding site layer deposited at least on the surfaces exposed through the mask, then a second masking layer is formed covering at least the areas exposed by the first mask and the parts of the seeding layer left exposed are etched away. Finally both masking layers are removed to expose the required seeding site layer. Vapour deposition of semi-conductor material then results in a layer which is polycrystalline over areas covered by the seeding site layer and monocrystalline elsewhere. Typically the substrate and seeding site layers are of silicon and the masking layers of silicon oxide or nitride. The masks are shaped using photo-resist and etching steps and the exposed parts of the seeding site layer etched away in a hydrofluoric-nitric acid mix. The seeding site layer is at least 50  thick so that areas covered by it can be visually distinguished from the adjacent oxide to facilitate registration of the masks. Where substrate and seeding site layers are of germanium, sodium hypochlorite is used as an etchant.

The movable valve member 30, in the form of a sleeve, carries a copper ring 36 which lies adjacent to a fixed coil 37. To operate the valve a capacitor is discharged into the coil 37; the ring 36 is repelled and sleeve 30 moves to the left into engagement with seat 33. This allows compressed gas from conduit 7 to enter the central bore of the valve which is connected to the operator of a high voltage electric switch (not shown). After a delay the compressed gas fills a space 40 driving a piston 39 to the right to reset the valve. In the position shown the gas pressure retains the sleeve 30 due to the difference A 3 -A 2  in diameters. In the other position the sleeve is retained due to the difference A 2 -A 1  in diameters. A spring 38 assists in resetting the valve. A more complicated version of the valve is described (Fig. 3, not shown) with rearranged gas channels and in other embodiments (Figs. 4, 5, not shown) the valve is reset by a second electrodynamic device. The capacitors are discharged into the coils by means of photothyristors (11, 12) (Fig. 1, not shown) triggered remotely by flashing lamps (15, 16).
