Abstract: Optical fibre cables are produced containing an extruded support member ofthermotropic liquid crystalline polymer in which the extrusion conditions are used to control the thermal expansion coefficient of the support member. The support member may be extruded on to the support member. In this case extrusion conditions may be used to induce a compressive strain on the fibre which can counteract the thermal change in length of the fibre when subject to temperature variations so that a cable having an optical path length which is less sensitive to temperature variation can be produced. Support members which provide a loose fitting sleeve over the fibre can be produced by control of extrusion conditionsto have a thermal expansion coefficient of not less than -5×10 -6 /°K.

Abstract: A dual-chain sewing machine for aligning the edges and the corresponding seam tracks of pieces of a garment that have different curvatures and for sewing the pieces together along the seam tracks includes two flexible, elongated carriers, which move at approximately the same linear speed and which are mounted and arranged for motion around continuous paths. Each carrier has pins extending from it in a direction transverse to the direction of movement, with the pins of one carrier extending towards the pins of the other carrier. A first fabric piece is applied to the pins of the first carrier when a pin bearing portion of the first carrier is in a path segment corresponding to the seam track on the first fabric piece; a second fabric piece is applied to the pins of the second carrier when a pin bearing portion of the second carrier is in a path segment corresponding to the seam track on the second fabric piece. The second carrier is guided towards the first carrier so that the pins of the first carrier engage the second fabric piece, and then the second carrier is guided away from the first carrier. Consequently, the second fabric piece is transferred from the second carrier to the first carrier and aligned with the first fabric piece already on the pins of the first carrier. The first carrier transports the fabric pieces to a sewing machine, which sews them together along the desired seam track.

Abstract: An electret fiber sheet has polarized charges on its surface and preferably has charges in ordered orientation across it. The polarized charges are present in an amount of at least 7 × 10 -11  C/cm 2 . Such sheets are found to have a high dust collecting efficiency. Sheets having an amount of polarized charge even as high as this are nevertheless stable when they have a maximum activation energy of depolarization of at least 0.2 eV. 
     Such an electret sheet can be obtained by a process comprising placing a fiber sheet between a non-contact type voltage-application electrode and an earth electrode confronting each other and supplying electricity (voltage > 3 kV; current density > 1 x 10 -6  mA/cm 2 ) between the electrodes, provided that the fiber sheet has a weight no more than 80 g/m 2  and a covering factor of at least 60%. 
     The electret fiber sheets are useful in a variety of applications, such as filter materials, especially for collection of micro dust; clothing and furniture apparel for industrial clean rooms; adsorbing materials; and medical materials such as masks and collectors of bacilli.

Abstract: The suppression of the reverse injection of the carriers in a bipolar transistor, without adversely effecting forward injection, is carried out by modifying the energy gap characteristics of the transistor so that a greater barrier to reverse injection is presented than that which is confronted by the forward injected carriers. The energy gap of the emitter is increased, relative to that of the base, through ion implantation. The ions which are implanted are such that the resulting compound material has a higher energy gap than that of silicon into which they are implanted to selectively modify the emitter region so as to locally increase its energy gap. Preferred materials include carbon and nitrogen.
