Title: Improvements in or relating to the production of rubber threads and the like and products containing the same
IPC: B29D99/00
Filed: 1941-02-10
Abstract: 545,882. Rubber threads and other articles. SHEPHERD, T. L. Feb. 10, 1941, No. 1792. Drawings to Specification. [Class 70] Rubber, particularly in the form of thread, of low extensibility is formed by stretching the rubber, prior to vulcanization, beyond its elastic limit and subsequently vulcanizing it at a temperature below the annealing temperature and while not under tension. The rubber may be compounded with vulcanizing ingredients or may suspended in a solution or dispersion of these ingredients such that vulcanizing takes place during storage at between ordinary temperature and 50‹C. The vulcanized rubber recovers its extensibility to a small extent on subsequent heating, which may be effected after the thread has been woven into cloth. A latex mix containing ultra-accelerators such as sodium isopropyl xanthate, diethyl ammonium diethyl dithiocarbamate &c. together with zinc oxide, antioxidants, stabilizers &c. is extruded in the form of thread into a coagulating bath. The thread is stretched, dried at a temperature below 65‹C. and wound either directly on to collapsable swifts or first on to bobbins, drums &c. and then on to collapsable swifts. The hanks are removed from the swifts and allowed to hang free from tension until vulcanized. Specifications 423,997 and 520,092, [Group XXVIII], are referred to.

Title: Automatic pilot systems for aircraft
Inventor: PARKER ROBERT HUGHES
IPC: B64C13/22
Filed: 1968-01-18
Abstract: 1,218,471. Automatic control of aircraft. SPERRY RAND CORP. Jan.18, 1968 [Feb. 6, 1967] No.2796/68. Heading G3R. In an aircraft automatic pilot, the datum of a closed-loop attitude control system is proportionally adjusted by applying force to a manual controller above a predetermined threshold value in one mode of operation and above a higher predetermined threshold value in another mode of operation, the first mode of operation being re-established if the higher value is exceeded in the second mode. In Fig. 1, an aircraft is automatically stabilized about its roll axis by electrical signals, from a synchro receiver 29 associated with a gyro vertical 20 and from a roll rate gyro 21, which are applied through amplifiers 22, 23 to operate ailerons 9 through hydraulic actuators 16, 11 arranged in series. Transducers 17, 18 associated with actuators 16, 11 apply follow-up signals to the input of amplifier 23. The attitude thus maintained about the roll axis may be varied by unclamping a servomotor 27 which then adjusts synchro 29 in dependence on signals applied to servo-amplifier 26 from either (a) a manual controller 36 (b) a gyro-magnetic compass 35 or (c) a radio beam capture and on-course receiver 51 associated with a three-term controller 37, according to the mode of operation selected by the setting of the switches shown, which may be transistors under the control of logic circuitry (not shown). Means 39,34 limit the angle of bank and its rate of change respectively. Alternatively, the aileron actuator may be adjusted by servo-assisted pilot and co-pilot control wheels 10 which are given feel at 14 and are associated with a suitably biased A. C. force transducer 45 signals from which, if large enough, are applied through a threshold device 46 and demodulator 44 to amplifier 26. The threshold is increased by the switching of a resistor 66 in certain modes of operation which are cancelled when the threshold is exceeded by operation of the control wheels. If the angle of bank is less than 5 degrees servomotor 27 operates as a positional servo but if it is greater than 5 degrees positional feedback is removed at 31 and servomotor 27 operates as a rate servo to provide integral action. Various interlocks are provided to ensure correct operation and synchronization of the gyro signals is arranged for during manual control. Control wheel signals, for example can only over-ride the radio beam signals when the latter are above a predetermined level at 40.

Title: Method of and apparatus for knitting
IPC: D04B9/38
Filed: 1960-01-27
Abstract: 914,585. Knitting-machines. PHILIP, M. Jan. 27, 1960, No. 2936/60. Class 74 (2). A rib machine has means for individually deflecting the needles of one bed in relation to those of the other to enable the pattern of the fabric to be varied. For example, the alternate needles in the one bed may be deflected so as to project between the alternate spaces between the needles in the other bed whereby a 2 X 2 rib fabric is followed by a 1 X 1 rib fabric. As described in connection with a cylinder-and-dial machine, where it is desired to change from a 2 Î 2 to a 1 Î 1 rib formation, the dial needles 264, 265 are initially spaced so as to project in pairs between pairs of cylinder needles 266, 267, thereby enabling the 2 Î 2 rib formation to be produced. The alternate dial needles 264, 264<SP>1</SP> ... are then flexed by members 232 adapted to be pivoted by a cam 40 so as to press on the side of the needles and as they are projected to cause them to pass between the needles of each pair of cylinder needles as illustrated by the dial needle 264<SP>1</SP> positioned between the cylinder needles 266<SP>1</SP> and 267<SP>1</SP> in Fig. 9. The members 232 eventually ride off cam 40 and the flexed dial needles retain this deflected position by being restrained by the adjacent cylinder needles. During the deflection of the needles the knitting movement of all of the needles has been continued without any variation whereby the 1 X 1 rib formation is thereby commenced and by successive deflections of the needles the formation of 1 X 1 rib is continued. When the cam 40 is withdrawn the needles resume their normal operating movements and a 2 X 2 rib formation is again knitted. The invention can be applied to a single or multi-feeder circular machine or to a flat machine. In the case of a multi-feeder circular machine a cam 40 is provided for each feeder and is controlled by a cam to advance and retract it as desired for the pattern. Other effects beside 1 X 1 and 2 X 2 rib formations may be produced by selecting which needles are to be deflected. Specification 835,252 is referred to.
