Abstract: 1,032,557. Corrugating asbestos-cement sheets. CENTRE DE RECHERCHES DE PONT-AMOUSSON. Feb. 4, 1964 [Feb. 13, 1963], No. 4637/64. Heading B5A. A sheet F of asbestos-cement or the like is corrugated in apparatus which comprises an upper member II with a surface having the desired corrugations and a lower member I with parallel bars 2 and 12 which conform with the hollows of the upper member. The bars 2 which support an elastic apron 11 are fixed in height and their spacing is variable on transverse bars supported in fixed frame 1. The bars 12 are of fixed spacing and their height is variable by means of an hydraulic jack V. The sheet F is reduced in width by inward movement of the bars 2 to a spacing of twice the pitch of a single corrugation, the member II is lowered to engage the supported portions of the sheet in alternate hollows and then the portions of the sheet between adjacent bars 2 are raised into the unoccupied hollows by the bars 12. To separate the sheet F from the apron 11 and transfer it to an exit, suction is applied to the sheet through perforations 22 in member II which is then raised and moved relative to frame 1. The bars 2 and 12 may be mounted on a carriage movable between the sheet manufacturing station and the corrugating station. The movement of bars 2 and 12 may be achieved with rack devices or other mechanical means.

In a manual controller of an aircraft autopilot system, as described in Specifications 662,831 and 662,832, the control column is mounted on a gimbal ring so as to be movable about both the fore and aft and transverse axes. Movement about the latter axis effects operation of the pitch control while, movement about the former controls both ailerons and rudder simultaneously. As shown, the control column 62 is manually movable about axis 64, 68 against the restraining springs 69, 71 and signals are injected into the pitch, bank and rudder control channels by the induction devices 45, 37, 41, respectively. Movement of 62 about axis 64 causes motion of rod 116 along axis 68 which effects rotation of winding 47 through linkage 118, 121, 120. Winding 46 is energized from the pitch take-off of the auto-pilot and the output from 47 is applied to the elevators. Movement of 62 about axis 68 similarly effects rotation of windings 39, 43; windings 38, 42 are energized from the bank and rate-of-turn pick-offs respectively and the outputs from 39, 43 are applied to the ailerons and rudder respectively. The rudder signal is adjusted for wind speed by the gearing 87, 92 and the set screw 91. Separate manual adjustments of the elevators and ailerons can be made to knobs 53, 61. Switch 104 disconnects the auto-pilot compass during operation of 62. Specification 662,836 is referred to.

Abstract: 1300241 False-twisted composite yarn KUNSTSEIDEN AG 2 Feb 1970 [19 Feb 1969] 4816/70 Headings D1F and D1W In a process for the production of a woollike composite yarn by false-twisting, fixing the false-twist and winding the yarn after it has been twisted back, one or more multifilament yarns 8 are delivered freely to a multifilament core yarn 1, within the false-twist zone, either perpendicularly or substantially perpendicularly to the axis of the core yarn, before entering a false-twist spindle 10. The yarn 1 is delivered by a mechanism 2 to a heater 5 and false-twist spindle 10, from which it is delivered by mechanism 12 to a wind-up mechanism 13, 14. The composite yarn may be subjected to a second fixing treatment and then to twisting after it has been wound up. The cover yarn or yarns 8 may be delivered to the core yarn 1 at a point 9 which may be before or after the heater 5. The cover yarn or yarns 8 are preferably fed to the contact point 9 by independently driven mechanisms 7, and the point 9 is allowed to move freely whereby knots are formed in the cover yarn at irregularly spaced intervals along the core yarn. The effects produced in the yarn can be varied by suitable variations in the following parametres: the delivery rate of the cover yarn; the take-off rate of the delivery mechanism 12; the rotational speed of the false-twist spindle; and the delivery rate of the core yarn. The delivery rates of the cover yarns may be subjected to brief fluctuations in accordance with a predetermined programme. The cover yarn or yarns 8 may be delivered in a twisted or untwisted state and are preferably overfed relative to the core yarn.
