Heat crimpable composite filaments are produced by simultaneously melt-spinning through the or each extrusion orifice of a spinneret two fibre-forming polymers selected from (1) a polyester which comprises at least 75% by weight of the recurring structural unit (2) a polyester-ether which comprises at least 75% by weight of the recurring structural unit and (3) a polymer comprising from 98 to 70 mol per cent of the recurring structural unit (I) or (II) and from 2 to 30 mol per cent of the recurring structural unit wherein n is an integer of 2 to 6 and R is a hydrogen atom, or a methyl, ethyl, cyclohexyl or -SO 3 Na group. The filament thereby formed is a composite filament in which the polymer components are arranged and bonded together either in a side by side or in an eccentric sheath-core relationship along the entire length of the filament. The polymer (3) may be a ternary polymer comprising at least 70 mol per cent of the recurring structural unit (I) or (II), 5 to 20 mol per cent of the recurring structural unit (III), the remainder being another polyester forming constituent. In the ternary polymer the recurring structural unit (I) may be a unit of polyethylene terephthalate and the said other polyester forming constituent may be a unit of polyethylene hydroxybenzoate. Alternatively the recurring structural unit (II) may be a unit of polyethylene hydroxybenzoate and the said other polyester forming constituent may be a unit of polyethylene terephthalate. The said recurring structural unit (III) may be produced by the polycondensation of a hexahydroisophthalic acid or the specified derivatives thereof in which the cis-type and the trans-type are mixed and a diol having from 2 to 6 carbon atoms. The composite filament may be drawn, e.g. at an elevated temperature or in the presence of a swelling agent. The filaments may be caused to develop crimps by immersion in boiling water for a few minutes under no load or loads up to 5 mg./denier.

Filed: 1970-10-15
Abstract: 1320975 Analogue/digital converters GENERAL ELECTRIC CO 15 Oct 1970 [23 Oct 1969] 49053/70 Heading G4H In the receiver of a communication system an automatic band synchronizer senses the optimum sampling time for an analogue/digital converter 22 (Fig. 1) by generating a sampling pulse train at a rate equal to the transmitted data rate and determines the average time of occurrence of zero slope of a received analogue waveform to synchronize the sampling pulse train therewith. As described the analogue input is fed via a demodulator 13 to a variable transversal type filter 10, 11, 12 the output (a, Fig. 2, not shown) from which it is fed both to the A/D converter 22 and zero slope detector 17. The positive going output pulses (b) from the latter trigger a monostable 18, logic circuit 19 giving an output at the next pulse from a clock generator 15 phase locked to the transmitted data rate appearing at the receiver input. Up/down counter 20 is incremented or decremented in accordance with whether the output of the logic unit 19 leads or lags the negative going output of the sampling pulse train (e) of the A/D converter. Overflow (i) and underflow (h) pulses from the counter are fed to an adaptive threshold circuit 23 which prevents hunting by only transmitting a signal to digital phase shifter 24 when it has received two consecutive, overflow or underflow pulses. The digital phase shifter, fed with the output of clock generator 15, inhibits or adds a single clock pulse to the 64 band signal at its output, this signal being divided by 64 before being used for sampling the analogue signal. Consequently the digital phase shifter advances or retards the phase of the sampling signal.

Title: Improvements in or relating to fire-resistant fibre board
IPC: D21J1/16
Filed: 1963-12-13
Abstract: Fire-resistant fibreboard is made by preparing a wet layer of wood fibres, applying a suspension of mineral fibres upon the woodfibre layer to form a layer of mineral fibres, and dewatering the composite wet mat through the wood-fibre layer.  The fibres of the two kinds are used in such quantity that the thicknesses in the final dried board of the layers of mineral and wood fibres are at least 2.5 and 6 mm. respectively.  The wet mat may be pressed at room or elevated temperature, and may then be finally dried in a fan drier or in a heated press.  The mineral-fibre layer may be sized, e.g. with starch or a melamine-formaldehyde or urea-formaldehyde resin, or a sizing agent in the form of starch, carboxy-methylcellulose or an emulsion of an alkyd or vinyl resin or acrylate may be sprayed on to the web before or after the press section.  Mineral-fibre layers may be applied on both sides of the wood-fibre layer.  The mineral fibres may be of mineral wool, asbestos, slag wool or glass wool.  The board of the invention will damp sound transmission in buildings.  The starch solution used for sizing may contain an emulsion of tall oil. The tall oil is emulsified in water by adding concentrated ammonia and stirring.  This emulsion is then added to a solution of starch.

Title: Method of manufacturing a cylinder liner for an internal combustion engine
IPC: F02F1/14
Filed: 1975-12-04
Abstract: An annular cooling tube (1) is to be embedded in the cylinder liner (7). For this purpose, radially extending cooling-water inlet and outlet branches are welded to the cooling tube (1) and supporting webs (4) are secured along the entire circumference. These project beyond a surface which limits the cylinder liner to be produced. A stabilising ring (6) lying to the outside of the surface bounding the cylinder liner and surrounding the ends of the supporting webs is attached to the supporting webs (4). This ring is inserted into a core box and compacted with the core sand surrounding it to form the core. After the removal of the core (8) from the core box, the unit thereby obtained is placed in a casting mould (9) provided for the casting of the cylinder liner and the mould is then filled. Finally, the cylinder liner is removed from the mould (9) and those parts of the supporting webs (4) which project beyond the boundary surface are removed together with the stabilising ring (6). The process prevents unwanted shifting of the cooling tube during the pouring process. <IMAGE>
