Abstract: A drive mechanism has two parallel shafts (2,3) provided with overlapping circumferentially-extending spiral teeth (4,5) of the same hand. The shape and positioning of the teeth is such that when one of the shafts is rotated, the steep flank surfaces (7,9) of its teeth engage the steep flank surfaces (9,7) of the teeth of the other shaft and force it to rotate in the same direction. Unidirectional drive may be obtained by providing each tooth with a gently sloping flank surface (8,10) on one side. The engagement of the gently sloping flank surfaces prevents rotation of the shafts if the driving torque is reversed.

Abstract: A driveline is provided for vehicles with two or more driving wheels in which power is carried between the transmission and each wheel through a parallel shaft differential with two internal gear pairs. A traction balance, connecting the differentials, counterbalances reactive torque. Relative wheel traction is varied by change gears within the traction balance or by control torque applied to traction balance components.

Abstract: A microfilter (4) for fitting into a filter-box of an infants incubator comprises a pad (22) of non-woven filtering material enclosed in an envelope (21) of water-repellent cohesive and non-woven material which is highly permeable to air and oxygen. The envelope prevents the escape of fibrous particles from the pad and has one side colored differently from the other to reduce the risk of being replaced back-to-front in the filter-box. The envelope may be placed in a similar envelope. It may also have one face of multilayer construction with the layers individually removable so that they can be discarded when dirty.

Abstract: A calender comprises at least one pair of rolls through which a web to be calendered runs. One roll in each pair of rolls is a hard roll which is a heated metal roll, and the other roll in each pair of rolls is a roll provided with a resilient coating. The face of the roll with the resilient coating is also heated to a high temperature, advantageously to the same temperature as the heated metal roll.

Abstract: The present invention constitutes a portable neubulizer capable of producing a finely divided aerosol having uniformly sized droplets. The nebulizer includes a source of fluid such as a capillary tube coupled to a fluid reservoir to which a high voltage is applied in order to generate the aerosol by electrical atomization. The nebulizer further includes a piezoelectric crystal and a mechanism for deforming the crystal so as to generate the required voltage. By using electrical atomization to generate the aerosol and by piezoelectrically generating the voltage required for atomization, a nebulizer is provided which may be of small size so as to be suitable for hand held operations yet is capable of producing measured amounts of finely divided aerosols which are substantially monodispersed.

Abstract: A video effects generator consists of two major components: an electronic video switch and a waveform generator. The switch can give either sharp or soft edges, fade in or out or fade between the two inputs. This switch is driven by a waveform generator to provide switching at a line rate, field rate or both. Effects result when two video sources are alternately selected within the time of one field.

Abstract: A method and apparatus for fitting aircraft having manually operated escape slide girt bars with a mechanism that automatically engages the girt bar in a floor mounted bracket as the entry door is latched, releases the girt bar from the floor bracket when a foot pedal is depressed as the door is unlatched in non-emergency circumstances, and releases the girt bar from the door when the door is opened in emergency situations for deploying an escape slide. Support arms having spring loaded tongues on their remote ends are connected to the girt bar, while brackets in the door each receive one of the spring loaded tongues and hold the same in tongue retaining fittings. The tongue retaining fittings normally push the girt bar out of the floor brackets as the door is unlatched prior to opening and are provided with hinge tab stops to engage support arm hinge tabs on the girt bar support arm to lift the girt bar off of the floor as the door is unlatched prior to opening with the foot pedal depressed.
