Inventor: CROSS BERNARD JOHN
IPC: C08F4/654

Abstract: A particulate solid is formed from a compound of the general formula Mg(OR) x X (2-x)  where R is Rʹ or CORʹ, Rʹ is a hydrocarbyl group, X is a halogen atom and x is greater than 0 up to 2, the particles of the solid being essentially spherical. The solid can have a surface area of at least 15 m²/g, and the surface area may be at least 50 m²/g. The solid is porous and may be capable of absorbing at least 0.6 cm³ of ethanol per gramme of solid. The particulate solid may be obtained by spray drying a non-particulate material, preferably by comminuting the non-particulate material in the presence of a liquid medium, and desirably an attrition inhibitor, and spray-­drying the comminuted mixture. The particulate solid can be reacted with a transition metal compound such as titanium tetrachloride and preferably with a Lewis Base compound such as the ester of an aromatic carboxylic acid. The transition metal composition obtained is useful for the production of olefin polymerisation catalysts of high activity and stereospecificity. The polymers obtained have an essentially spherical particle form and are porous, for example having a porosity of at least 0.2 cm³/g as measured by mercury porosimetry. The polymers typically have a mean particle size of at least one millimetre.

Abstract: A novel thermal ink jet printhead and related methods of operation are described. Methods of manufacture of the printhead wherein multiple heater resistors (18,20) are connected in series between a source of ink supply (10) and an output ink ejection orifice (24). A primary heater resistor (20) is located in an ink ejection chamber (16) and adjacent an output ink ejection orifice (24). This resistor (20) propels ink away from the printhead, whereas another heater resistor (18) (or resistors) is removed from the primary heater resistor (20) and is located in an adjacent ink injection chamber (14), and is operative to inject ink toward the primary heater resistor (20). In this manner, ink ejection operational frequency is increased and cavitational wear on the heater resistors (20) is minimized. Simultaneously, hydrodynamic back pressure in the ink ejection chamber (16) is reduced, and control over ink drop size and viscosity is improved.

Abstract: In known detector circuits for speech signals, after bandpass filtering to obtain the fundamental speech frequency of the microphone signal, the speech envelope of the said signal is detected and the detection signal used for control of a control amplifier in such a way that this amplifier attenuates the microphone signal when the detection signal is absent and amplifies the microphone signal when the detection signal is present. A method of this kind results in a detection time of the order of magnitude of 200 ms. The new method is intended to permit a shorter detection time. This is achieved by the fact that the signals occurring at the output of the low-pass filter are checked for amplitude and for the duration of a defined amplitude and that a speech signal is detected if at least three sequential amplitudes have occurred in the range of the fundamental speech frequency. The detection of speech signals can be performed particularly in combination with a signal processor for controlling the amplification of microphone signals in an environment filled with interfering noise, amplification taking place only when speech signals are present; it can also be used in intercom or two-way communication systems to amplify the signal in the appropriate direction and attenuate it in the opposite direction when a speech signal is present. <IMAGE>

Abstract: The sealing-in of a discharge vessel (4) of a sodium high pressure discharge lamp contains a plug (7) made of ceramic which is sintered into the end of the discharge vessel (4). The plug (7) consists of a cylindrical part (12) and a conical part (13). The cone faces the electrode (10, 11) and extends up to the electrode spiral (11). Moulded onto the outer surface of the conical part (13) are pockets (14) which are separated from one another by webs (15), and in which the metallic filler substances, electrically insulated from the power supply (8), become condensed. Due to the construction, an improved coaxial alignment of the plug (7) in the discharge vessel (4) is effected. Moreover, there is an improved heat transition from the tube (6) into the plug (7), by which means an increased cold spot temperature is achieved. The discharge vessel is thus suitable for colour-improved lamps and for plug-in types. An improvement is also achieved in respect of the vibration resistance of the lamps.

Abstract: In the neighbourhood of information processing and telecommunication systems, data signals, which are exchanged within that system, can, due to electromagnetic emission outside the relevant system, to a greater or less degree, be received - in a wireless way - and - generally after the received signal has been restored - be reproduced and displayed. The present invention relates to a measuring method and a device for determining a characteristic value indicating the degree to which data signals of a digital information processing system are reproducible outside that system. According to the invention a signal (3) received outside the information processing system to be tested is compared with a threshold value (5), and converted into a binary signal (6), of which the relatively shortest time (t₀) between two consecutive starting times of the ascending pulses is determined, said characteristic value being proportional to that number of ascending pulses for which it applies that the time (t x ) between the starting time of that ascending pulse and the starting time of the ascending pulse preceding that pulse is, within certain tolerances, equal to {(n *t₀) / 2}, in which t₀ represents said relatively shortest time and n is a random natural number from the series {3,4,5,...}.

Abstract: Apparatus for continuously manufacturing plastic-lined metallic pipe (22). The apparatus includes an extruder (28) having an output providing a plastic sleeve and further includes a continuous roll-forming tubing mill production line. This production line (20) includes a series of forming rolls which progressively deform a substantially flat steel strip to a generally tubular configuration as the strip moves along a straight-line longitudinal path. The production line further includes an electrical resistance or high frequency welder (38) which continuously welds the lateral edges of the moving strip to complete the pipe. The apparatus also includes a feed for the plastic sleeve (24) into the incipient metal pipe (26) upstream of the welder. The plastic sleeve has an outside diameter slightly smaller than the inside diameter of the metallic pipe in its as-formed condition. Furthermore, the plastic sleeve maintains a generally tubular configuration from the time it enters the pipe until the manufacture of the plastic-lined pipe is completed. The exterior surface of the metal pipe can be galvanised (46) in the production line, or raw steel pipe can be lined and the exterior surface later painted. The production line also includes a sizing station (30) for reducing the inside diameter of the metallic pipe to substantially the outside diameter of the plastic sleeve. A method for continuously manufacturing plastic-lined metallic pipe using this apparatus is also disclosed.
