Title: Cathode ray tube apparatus
IPC: H04N9/28
Filed: 1978-11-27
Abstract: In a convergence circuit for a shadow-mask colour cathode ray tube, the square of a horizontal deflecting signal ex is multiplied by coefficients dependent on the quadrant of the screen in which the display is located, and the square of a vertical deflecting signal ey is multiplied by coefficients also dependent on the quadrant, the degree of convergence following the sum of four signals thus formed. Alternatively, an ellipse centreing the display surface is defined by aex<2>+bey<2>=ec where a, b, ec designate constants. The degree of convergence follows aex<2> +bey<2>=el inside of the ellipse while following aex<2>+bey<2>+K(aex<2>+bey<H N=0><2>-ec) outside of the ellipse where K is a variable constant. By changing K for each of the quadrants, the degree of convergence may be different between them.

Title: Liquid Pressure Control System
IPC: B27L11/04
Filed: 1978-12-18
Abstract: A liquid pressure control system advances logs (19), Fig. 8, towards a rotary cutter wheel (10) in timed relationship to successive cuts by cutters on that wheel (10).

Title: Method of producing thermoplastics moulding compounds using scrap materials
IPC: C08J3/00
Filed: 1979-06-11
Abstract: Fully cured scrap rubber is chopped and then granulated, after which the granules are mixed with granulated thermoplastics material by a mixing operation vigorous enough to raise appreciably the temperature of the materials being mixed. The resultant hot mass is formed into a slab which after being allowed to cool is granulated to produce a material capable of being extruded or injection moulded. The substance of the invention can be used for making any articles which can be extruded or moulded from unvulcanized rubber and possesses a degree of rigidity higher than is obtainable by the use of unvulcanized rubber alone. The invention solves the problem of providing a mouldable compound from scrap rubber which has already been vulcanized and which would in consequence be otherwise impossible to remould.

Patent GB-2069753-A (GB)
Title: System incorporating photoelectro-chemical cell
IPC: H01G9/21
Filed: 1980-02-13
Abstract: A system comprising a photoelectro- chemical cell (11) for converting light into electrical energy in combination with a thermosyphon for circulating the electrolyte from the cell through a heat exchanger (13) and back to the cell for cooling the electrolyte and cell and hence reducing detrimental corrosion and thermal expansion effects. The heat removed by the heat exchanger may be used as an energy source. The circulation reduces concentration polarisation between the photoelectrode and counter electrode of the cell enabling operation at higher current densities. The described system is thermally isolated from the ambient so that all the absorbed heat passes to the heat exchanger. Heat absorption may be increased by colouring the electrolyte and electrical output by shaping the housing of the cell to function as a lens. <IMAGE>

Patent GB-2075672-A (GB)
Title: Washpot for use with sampling probe
IPC: G01N35/10
Filed: 1980-04-17
Abstract: A washpot has a wash chamber 5 into which a reciprocable sampling probe 4 may be retracted so as to aspirate wash liquid into the probe and also to rinse the outside of the probe. To avoid the necessity for a seal on the outside of the probe to prevent leakage of the wash chamber 5 is so dimensioned that in use wash liquid fed via a line 8 will bridge the gap between the open end of the probe 4 and the end of line 8 when the probe is in the wash or upper position. The chamber 5 thus does not run in the wash mode. The clearance round the probe 4 in the upper passage 3 is minimal to prevent significant upward leakage of the wash liquid and an enlarged connecting chamber 6 connected to an aspirating exhaust line 9 prevents downward leakage. Passage 7 is large enough to allow droplets of sample on the outside of the probe 4 to be carried into the wash chamber. <IMAGE>

Title: A shielding type mining wall lining
IPC: E21D23/00
Filed: 1980-10-24
Abstract: A mining wall lining with a mechanism driving a roof-bar along a curved path (for example a lemniscate curve) is provided for tall beds having a height which is variable over a wide range. The prop 8 of the wall lining is supported in a socket of a bracket 6 located high on the sill piece. Also the hole 13 for fastening the respective link 14 is drilled in the bracket 6 and is located high above the sill piece 1. This makes the lining able to transfer large forces without fear of the props bowing. At the same time this wall lining has its minimum height considerably small compared to its maximum height by virtue of the particular location of the hole 13 high above the sill piece. The sill piece consisting of a base plate 15 and reinforcing beams 2 is rigid and has a large surface area of contact with the floor to prevent local stress concentration on the floor resulting from distortions of the sill piece. <IMAGE>

Title: Forming foundry moulds
IPC: B22C1/20
Filed: 1980-12-19
Abstract: To form a shaped foundry core or mould, a binder material comprising an ethylenically unsaturated monomer or polymer is distributed on a foundry aggregate, the aggregate is shaped into the desired foundry article, and the binding material is then polymerised by means of a free radical initiator comprising a peroxide and catalytic agent. The binding material is preferably a solution of an ethylenically unsaturated polymer in a solvent of unsaturated monomeric compound or compounds, in which vinyl or acrylic unsaturation is present. This binder is suitable as a foundry binder of the cold box type wherein a room temperature, rapid gas cure is utilized. The gas, preferably sulfur dioxide, serves as the catalytic agent of the free radical initiator. Alternatively the catalytic agent may be heat. The binder collapses readily after casting of aluminium and other lightweight metals to provide complete shakeout of the core with minimum application of external energy.
