Title: Machine to distribute bottles - uses a vibrating table and a device to ensure bottles are upright
IPC: B65B35/34
Filed: 1974-06-04
Abstract: The bottles pass from a storage bin into channels (10) on a vibrating table. A rotating brush prevents exit of the bottles except in the channels. The vibrating table is mounted on flexible mountings (14) and is motor driven. The bottles move along the channels and enter locations on a tilting device. If the bottles arrive neck first, the neck passes through an opening (37). When the device tilts, the base of the bottle clears the edge of the vibrating table and the bottle is pivoted round to be deposited base down on the exit channel (60). If the bottle arrives base first, the neck contacts the edge of the table when the device tilts, the bottle pivots then slides down a sloping surface (38) to the exit.

Title: Geothermal steam raising plant - pumps surface water into deep wells with parallel steam tubes and piston and flap valves
IPC: F03G7/04
Filed: 1975-03-13
Abstract: A deep bore is dug in an area where geothermal energy is available. Two tubes (3, 7) of suitable metal are inserted side by side in this well. They are separate along their whole length but joined at the bottom. Surface water is pumped down one tube and is vaporised by the natural heat in the earth. The resulting steam rises up the other tube and is collected in a receiver (5). It can be superheated by electric heaters on the outlet of the receiver. A piston at the base of the tubes is depressed by the pressure of the water and raised by the pressure of the steam. It serves to prevent steam rising up the down coming water tube.

Title: Detection of fertile period and pregnancy - with test kit contng. buffer and cpd. hydrolysable to p-nitrophenol etc.
IPC: C12Q1/34
Filed: 1975-03-28
Abstract: New test kit for determining an increase in N-acetyl-beta-glucosaminidase in female body fluids (i.e., for determining the fertile period or pregnancy) consists of: a bibulous absorbant strip impregnated with a non-toxic buffer (A) (to maintain pH 4-5) and a colour indicator (I). The strip is moistened with saliva, or cervical or vaginal fluid. Any colour that develops is further intensified by the addition of a buffer (B) (to maintain pH 9-11). The presence of a colour indicates ovulation or pregnancy. (I) may be alpha-naphthol-N-acetyl-beta-d-glucoraminide, 1- p-nitrocatechol -N-acetyl-beta-d-glucosaminide, 3,3-bis-(p-hydroxyphenyl)phthalid-N-acetyl-beta-d-glucosaminide, or pref. p-nitrophenyl-N-acetyl-beta-d-glucosaminide (II). Safe, simple, reliable test is very accurate, and readily detects ovulation (the fertile period; for conception or rhythmic contraception). Method also allows the diagnosis of pregnancy to be made as early as 10 days after fertilisation.

Title: Letter or number display for transport - uses precut figures which can be bent so as to be slotted into support
IPC: G09F7/08
Filed: 1975-04-15
Abstract: The display system is of the type having a support panel and individual precut signs which can be fitted onto the support so as to form a message.

Title: IC engine torque increasing device - has springs inside segmented piston to store compression energy at beginning of stroke
IPC: F02B75/36
Filed: 1975-07-10
Abstract: The piston of the internal combustion engine is made in two parts. The upper part (1) is attached by sliding bolts to the lower part (3). Compression springs (1) are fitted around the guide bolts so that there is normally a gap between the two parts of the piston. When the engine fires, the sudden rise in pressure in the cylinder presses the upper part (2) of the piston against the lower part (3), and energy is stored in the springs (1). As the crankshaft (5) rotates and the inclination of the connecting rod (4) increases, the force exerted by the expanding springs (1) transmits an increased torque to the crankshaft (5).

Title: Stain repellent unglazed tiles - contg. invisible water and or oil repellent layer formed by double impregnation with reactive components
IPC: C04B41/45
Filed: 1976-06-11
Abstract: Stain-repellent unglazed tiles contain an invisible oleophobic and/or hydrophobic barrier layer near surface. The layer is formed by impregnating absorbent tiles with >=2 reactive components and allowing components to react below tile surface. In a pref. process, the tiles are impregnated, on surface, with a first liq. compsn., used in amts. such that the ceramic body is not completely soaked through. The surface is left to dry. A second liq. compsn., which reacts with the first liq. compsn. to form an oleophobic and/or hydrophobic reaction prod., is then applied to surface, following which the tiles are dried, opt. with heating, to 50-250 degrees C. The tiles are esp. coloured, e.g., clinker- or earthenware, floor tiles. Tiles are rendered oleophobic and water-repellent. Tile appearance, gloss, colour and heat-insulation are unchanged. Pores are not filled and tiles remain vapour-permeable, allowing escape of moisture from core and drying after they are laid. Visible "blooming", when using an incorrect mortar for applying tiles, is prevented. Barrier layer is sufficiently low to escape erosion in use. Barrier prevents grout from penetrating into pores. A pause between application of the 2 impregnating agents, improves stain-resistance of layer.
