Abstract: A novel graft copolymer capable of imparting to a polyolefin when blended therewith a good balance of tensile modulus, sag resistance and melt viscosity, is a polyolefin trunk having a, preferably relatively high weight-average molecular weight, methacrylate polymer chain grafted thereto. The graft copolymer is formed by dissolving a non-polar polyolefin in an inert hydrocarbon solvent, and, while stirring the mixture, adding methacrylate monomer together with initiator to produce a constant, low concentration of radicals, and covalently graft a polymer chain, preferably of relatively high molecular weight, to the polyolefin backbone. The graft copolymer can be separated from the solvent, by volatilizing the solvent, for example in a devolatilizing extruder, and pelletised or extruded or otherwise shaped into a desired shape such as a sheet, tube or the like. This graft copolymer can be blended with a polyolefin matrix to improve its physical properties in the melt, upon cooling, and in the solid state, and is useful in cast and oriented films, solid extruded rod and profile, foamed rod, profile and sheet and blown bottles. The graft copolymer can also be used to improve compatibility between polymers in a wide range of polymer blends.

Abstract: A method and apparatus for keying TV signals. A keying signal, K, is employed to create first and second modified keying signals, K(A) and K(B), which commence at independent points in time. The modified signals are compared and, as a result, a revised keying signal, R, is produced commencing at the leading edge of one modified keying signal and terminating at the trailing edge of the other. The operator selects R according to one of two rules (i), (ii), the selection being by trial and error: 
rule (i): 
if K(A) > K(B) then R = K(A) 
if K(A) < K(B) then R = K(B) 
rule (ii) (which is the converse of rule (i)): 
if K(A) > K(B) then R = K(B) 
if K(A) < K(B) then R = K(A). 
In this manner, the revised keying signal R can be made to coincide with the video signal, V, to be keyed.

Abstract: An ink jet printhead fabrication process produces a plurality of printheads from two mated substrates (31,36) by two dicing operations. One dicing operation produces the nozzle face (29) for each of a plurality of printheads and optionally produces the nozzles (27). This dicing blade, together with specific operating parameters, prevent the nozzles from chipping and the nozzle faces from scratches and abrasions. A second dicing operation with a dicing blade severs the mated substrates into separate printheads. The dicing operation which produces the nozzle face is preferably conducted in two steps. A first cut makes the nozzle face, but does not sever the two mated substrates. A second dicing cut severs the two substrates, but does so in a manner that prevents contact by the dicing blade with the nozzle face.

Abstract: A means of analysing and of synthesising speech is described, using the simulation of the acoustic behaviour of a tube divided into segments with variable cross-section. The variations in cross-section of the various segments of a tube allow the generation of phonemes when an air pressure and delivery source is positioned similar to the human vocal cords. By simulation, these phonemes can be generated in the form of electrical signals delivered to a loud-speaker. The invention bears upon the choice of the lengths of the tube segments and relates this choice to the fineness of the approximation which it is desired to make. For an approximation with three formants (the formants are the resonant frequencies of the tube), the tube is divided into eight segments of successive lengths L/10, L/15, 2L/15, 3L/15, 3L/15, 2L/15, L/15 and L/10; L is the total length of the tube.

Abstract: The apparatus consists of: - a drainage tube (2a), 50 centimetres in length, to be inserted into the surgical wound;  - a two-way connection piece (2b); - a connection tube of 100 centimetres, connected to a two-valve "technical plug";  - an auto-aspirating bellows, By leaving the perforated drainage tube "in situ", the compression of the bellows alone activates the apparatus for the drainage of the physiological fluid which is situated in the wound. It is at no time necessary to disconnect the elements, which could infect the surgical wound. The drainage action is however achieved in a correct, precise, simple and rigorously aseptic manner. The duration of the drainage action is set by the surgeon.

Abstract: When an excessive acceleration spin condition is detected in one or both of the driven wheels (10,12) of a vehicle, braking pressure is applied to one or both wheel brakes to quickly take control of the respective excessive spin condition. A value representing the total engine torque being absorbed by both driven wheel brakes (18,20) above a predetermined low value is determined from which a desired engine torque reduction amount is determined. The actual engine torque output value is determined and reduced by the desired engine torque reduction amount resulting in a desired value of engine torque output. The engine torque output is then decreased to the desired engine torque output.

Abstract: In a telecommunication switching system the telecommunication software is implemented by means of independent software components referred to as objects. The objects communicate with each other by messages and symbolic names only. A runtime system includes a runtime linker which registers the systems components and records a data pointer to the components data. To communicate with another object, a source object transmits an executable expression, called a message, to the runtime system. The message includes the symbolic name and the identity of the method of the destination object. The runtime system serves only a single processor or group of objects and calls the destination object, by means of the identity of the method and the data pointer if the destination object is within the group of objects served by the runtime system. In the case a destination object is located on another processor, the runtime system will broadcast the message to other processors. In each of the receiving processors, the runtime system searches its linker table for the symbolic name of the destination object of the message and if found calls the destination object on the basis of the method identification in the message and the data pointer information in the runtime linker. Interprocessor messages include a source processor designation and the run system of each of the processors records the name of the source processor and the symbolic name of the source object when an interprocessor message is received. This table is consulted before broadcasting a message to a non-resident destination object and a direct processor-to-processor communication is established, instead of a broadcast, if the symbolic name of the destination object is recorded together with the corresponding processor identification, in the destination table.

Abstract: In the method, particles (16) are classified by locating them in a resonance cavity (10) and applying a swept range of microwave radiation to the cavity. The transmitted signals are detected and analysed. The particle is then assigned to a classification in accordance with changes in the dielectric characteristics of the cavity as a result of the presence of the particle. The radiation is polarised and is applied in at least two mutually orthogonal directions. With the particle located at the centre of the cavity, where the E-field is a maximum, and with signals propagating in at least two mutually orthogonal direction, account is taken of dimensional and orientational inaccuracies from particle to particle.
