Patent GB-2010712-A (GB)
Title: Assembly for uniformly distributing melt in an electromagnetic mould
IPC: B22D11/115
Filed: 1978-12-18
Abstract: Melt fed down from a trough 11 through one or more nozzles 12, into a region where it is moulded by electromagnetic force for solidification, is directed outwardly by a submerged dish 4 of a float device 1, in generally radial horizontal directions, in the same direction as the eddy flow at the surface of the poured melt. The dish 4 is secured by struts (e.g. four) to the bottom of a (sintered silica) float 2 on the melt surface. The device 1 is shown loosely attached for floating, by arms 6 on the annular float 2, to pins 13 on two slotted members connected by screws 15 on a beam 8 which can be raised or lowered by screws or, as shown, by levers 18 of cam mechanisms 9, 10, to determine the melt level. The level of beam 8 determines the lowest level of the dish 4 and the level of the melt trough 11 whose outflow through the nozzle(s) 12 is controlled by the dish. <IMAGE>

Title: A process for the dyeing of wool treated with an anti-felting agent
IPC: D06P3/20
Filed: 1979-10-19
Abstract: A process for the dyeing of wool which has been treated with an anti-felting agent using a metal complex of an azo dye which contains at least one sulphonic acid and/or at least one sulphonate group and in the presence of in the range of from 10 to 15% by weight (based on the weight of dry goods) of a non-colouring, inert, neutral alkali metal salt. This enables dyeing to be carried out at, e.g. 70-85 DEG C, when previously the dyeing of such wool had to be carried out at the boiling temperature of the dyebath to ensure a level and fast colouration. Dyeing at this temperature not only strained and hardened the wool fibres but was also costly in terms of heating energy.

Title: Fibre-suspension screen apparatus
IPC: B01D29/11
Filed: 1979-11-08
Abstract: The rotary agitator 20 of a fibre-suspension screening apparatus is driven at a speed varied according to at least one physical parameter of the fibre suspension measured on one or both sides of the screen 1, 2 to prevent clogging thereof. The parameter may be the pressure, flow rate or concentration of the suspension, and any variations from a predetermined level produce an automatic change in agitator speed to restore the status quo. As a result of this increase in speed of said relative movement, fibres and the like clogging the perforations of the screen plate or plates are completely or partially torn away, thereby increasing the screening capacity to a normal value. <IMAGE>

Title: Portable data acquisition and storage system for monitoring patient
IPC: G11C17/18
Filed: 1980-05-22
Abstract: The system enables ambulatory monitoring of a patient's blood pressure and heart rate without the need for the patient to wear a portable magnetic tape recorder. ECG electrodes and a blood pressure cuff are affixed to the patient and are connected to a blood pressure measuring apparatus worn by the patient. The Data Acquisition and Storage System (DAS) is connected to the blood pressure measuring apparatus and includes a solid state storage device in which the successive measurements are stored. After the monitoring session, which may last 24 hours, the patient returns to the clinic, where the DAS is connected to a stationary charter that prints and plots the stored data in tabular and graphical form. The DAS includes a clock for determining the time at which the readings are taken, and these times are stored along with the data. The clock also permits the heart rate to be determined and stored by the DAS. If the voltage of the power source should fall too low the DAS goes into a dormant mode to preserve already stored data. <IMAGE>

Title: Coating hot glass with metals or metal compounds, especially oxides
IPC: C03C17/00
Filed: 1981-01-26
Abstract: In the formation of a metal or metal compound coating on a face of a heated glass substrate during its forward displacement along a tunnel by contacting the substrate at a coating station in the tunnel with at least one stream of droplets comprising one or more substances from which said coating is formed, and simultaneously exerting suction forces in exhaust ducting to draw environmental gases away from that station, the coating may sometimes be spoiled by side reactions or by the spurious deposition of substances from the atmosphere within the tunnel. To help reduce this spoiling, the exhaust ducting comprises at least one exhaust duct (12, 13) whose entrance is located in said tunnel forwardly or rearwardly of the coating station and which forms or is associated with a barrier wall (16 and/or 17) located so as to prevent gases from passing over said duct, towards and into contact with the droplet stream(s) (9, 10). One or more oxide coatings of Sn (optionally doped with Sb, As or F), Cd, Mg, W, Fe, In, Ti or Co may be produced. <IMAGE>

Title: Lined conduits
IPC: G01M3/00
Filed: 1981-06-18
Abstract: A conduit for conveying a pulverised fuel/air mixture comprises an outer casing (34) surrounding an inner lining (30) of hard wearing material, the latter being releasably located within the casing (34) and being spaced inwardly from the casing (34) to define an annular clearance (36). Tell tale holes (54) may be provided in the casing (34) such that, on puncture of the lining (30), penetration of the coal/air mixture into the annular clearance (36) will be apparent due to leakage of coal dust through the holes (54).
