Title: Making emulsions and suspensions
IPC: C10L1/32
Filed: 1982-01-26
Abstract: Apparatus for producing emulsions and suspensions with a long- term stability comprises two quantity dosing pumps 20, 120 which are motor-driven and to which are supplied the two phases to be emulsified or suspended the constituents then being fed to a rotor/stator, as well as a mixing device 30 comprising a fixed, conical outer ring 34 provided with a tooth system and a conical rotary member 35 rotating in the outer ring 34 and provided with a tooth system corresponding to that of the outer ring. An annular clearance 36, is provided between the ring 34 and member 35 whose size reduces towards the discharge in the flow direction resulting from the conicity of the outer ring and the rotary member. The conical annular clearance 36 creates a vortex type flow through the metering device and the tooth systems formed in the lateral walls of the grinding clearance further create forming wall-reflecting, annular turbulence zones (Fig. 1). <IMAGE>

Title: Method of automatically adjusting the time at which a filling stream of material fed to an electromechanical balance is switched off
IPC: G01G13/30
Filed: 1982-02-19
Abstract: A method for automatically adjusting the time at which a filling stream of material fed to an electromechanical balance is switched off makes use of a probe (1), whereby the actual weight (m) in the weighing vessel is ascertained, either continuously or discontinuously at short intervals of time, during the filling period. The readings are fed via an amplifier (2) to a computer (3) and an interpreting device (4). In the computer (3) the filling speed <dm>/dt and then the precise flow lead K x <dm>/dt are calculated, K being a time constant specific to the balance in question. The computer values are fed to the interpreting device (4), which switches off the filling stream by means of a control signal, as soon as the sum of the actual weight and the computed flow lead is equal to the desired weight of material to be weighed out. <IMAGE>

Title: Fume cupboards
IPC: B08B15/02
Filed: 1982-03-24
Abstract: The interior of a fume cupboard 4 is connected to a suction fan 11 via ducting 8, 14 and in the ducting is provided a connection 12 to the outside atmosphere controlled by a baffle 13. The baffle position reduces the flow of air from the fume cupboard as it increases the flow from outside and vice versa, the position of the baffle being controlled by a servo motor of pneumatic cylinder operated by means responsive to the position of a sash window 5 on the fume cupboard. Raising the sash window 5 increases the airflow from the fume cupboard as it reduces the flow from outside, so that the velocity of air flow through the window aperture is maintained at a constant level and the exhaust velocity from the fan 11 is also maintained. <IMAGE>

Title: Trimming lampshades
Inventor: MANSEY KEITH WILLIAM
IPC: F21V1/26
Filed: 1983-06-22
Abstract: A method of trimming lampshades is disclosed which is applicable to lampshades of which the diameter at one end is less than at the other. Problems have been encountered when trimming lampshades with plastics trimming material which is rigid but flexible and substantially j-shaped in cross-section. In order to solve these problems accurately dimensioned endless rings 9, 10 are formed of the trimming material. A ring of trim used for the narrower end of the lampshade is heated to soften the plastics and shaped to conform to the narrower end to which it is subsequently adhered. The ring of trim used for the wider end of the lampshade has a circumferential length slightly less than that of the wider end and is forced over the end. By this means the edges of the rings lie closely adjacent to and follow the line of the lampshade. <IMAGE>

Title: A method of driving an active matrix panel of a liquid crystal display device
Inventor: MOROZUMI SHINJI
IPC: H04N3/12
Filed: 1985-04-26
Abstract: A method of driving an active matrix panel of a liquid crystal display device in which a video signal suitable for a cathode ray tube is used to write into an element (Pil-Pim) of the device via a thin film transistor (Tr) which during a selected period is turned ON by a gate line (Gl-Gm). The polarity of the level of the video signal is inverted alternately every field and written into the element from a data line (Dl-Dn). The level of video signal in the element (Pil-Pim) is held during a non-selected period during which the transistor is turned OFF.

Patent GB-2168201-A (GB)
Title: Transformer cores
Inventor: DANIELS MICHAEL ROY
IPC: H01F27/245
Filed: 1985-11-29
Abstract: High power transformer cores are made of laminations formed of steel strip which usually comes covered by an insulating coating providing a tensile stress on the steel in the rolling direction. Such a coating gives a minimum power loss when in the direction of magnetisation in the core. However at the joints and corners, where the direction of magnetisation is not in the rolling direction, it has been found that a higher power loss is achieved. Therefore, the tensile coating is removed from the joint regions 18, 19, and a compressive coating may be applied in its place. Alternatively or additionally the joint regions may be scribed to reduce the effect of the coating. <IMAGE>

Title: Metal alkoxide modified clays
Inventor: YAMANAKA SHOJI
IPC: C01B33/40
Filed: 1986-06-10
Abstract: A novel process for producing clay derivatives having porous structure comprises hydrolyzing a metal alkoxide such as Al(OR)3, Ti(OR)4 and Si(OR)4 in which each R represents a linear or branched hydrocarbon group having from 1 to 6 carbon atoms, deflocculating the resulting hydrolyzate with an acid to obtain a hydrous metal oxide sol, and reacting the sol with smectite. The thus obtained porous clay derivatives have larger interlaminar interstices and a larger surface area than conventional ones. The interstices can be arbitrarily controlled by the acid amount. In addition, the derivatives are thermally stable so that they can be widely utilized in various fields as pigments, encapsulating agents, adsorbents, catalysts, carriers for catalysts and the like.
