Title: Improvements in or relating to the treatment of wool and like fibres or materials made therefrom to render them unfeltable and unshrinkable
IPC: D06M11/30
Filed: 1943-04-17
Abstract: Wool or like fibres, yarns, or fabrics, are subjected to a mild chlorinating or brominating treatment controlled at a pH value of 4, and subsequently to a treatment with a peroxide in order to minimise felting and shrinking of the fibres.  The chlorinating agent may be a solution of sodium hypochlorite which had been acidified to a pH value of 4 by addition of hydrochloric acid. When the chlorinating liquid is exhausted, sodium sulphite or bisulphite is added to clear the wool which is then washed. Oiled wool tops may be treated and the wool may be protected by the presence of a sulphonated oil.  The sodium hypochlorite solution may be acidified subsequently to the complete impregnation of the wool.  The treating liquid may be circulated through the wool.  The peroxide treatment may directly follow the chlorination treatment, or it may be effected at any later stage in the treatment or manufacture of the wool fibres or materials. The first treatment is primarily to prevent felting and the second treatment is to reduce and prevent length shrinkage.  A warm solution of hydrogen peroxide containing ammonia and sodium silicate may be used for the second stage of the treatment.

Title: Improvements in or relating to printing machines
IPC: B41F17/00
Filed: 1923-03-06
Abstract: 211,719. Centore, E. March 6, 1923. Printing with flexible printing-surfaces.-A de. vice for printing designs on fragile articles of irregular shape, such as plates, of the kind comprising an article carrier with a flexible diaphragm for supporting the article and a type carrier with a flexible diaphragm carrying the design, the diaphragms being subjected to partial vacuum when positioning the article and to air pressure for making the impression, is provided with means for automatically centering the type carrier relatively to the article carrier, such means preferably consisting of coned members. Platen machines.-The hollow member a contains the article carrier c shaped on its upper surface to conform with the shape of the plate &c. to be printed. The upper surface of the plate carrier c communicates by passages d with a central passage e and nozzle f, which is connected to a vacuum and compressed air apparatus. Over the member c is stretched a rubber diaphragm f secured to the ring i held in position by a flange l on an outer ring k. The diaphragm j<1> to which the types or designs are secured is similarly fixed to the type carrier o by a ring i' held in position by a ring k<1>. Interfitting conical rims are formed on the edges of the rings k, k<1> accurately to centre the carriers c, o when they are brought together. The type carrier has a central opening p p and nozzle r communicating with a vacuum and air pressure apparatus. In operation, both carriers are first moved apart and subjected to vacuum action, by which the diaphragm f is drawn down on to the carrier c enabling the plate to be placed thereon, and the design carrying diaphragm j<1> is held against movement on the carrier o whilst the inking rollers are run over it. Escape of air between the diaphragms and their carriers is facilitated by radial grooves d<1> on the carrier c and concentric grooves on the carrier o, air vents n, u being also provided round the edges of the members k, k<1>. The carriers are then brought together and subjected to air pressure, which forces the diaphragm j<1> into contact with the inside of the plate to make the impression. Risk of breakage of the plate during the impression is obviated by the action of the air pressure under the diaphragm j. The rings i, i<1> on the two carriers are interchangeable. Printing-surfaces.-The design on the diaphragm j<1>, Fig. 3, is formed of portions v of vulcanized rubber stuck on strips x of spongy rubber secured by rubber solution to the diaphragm. To permit escape of air the strips x are perforated at x<1> and fluted strips y are stuck radially round the periphery.

Title: A stability augmentation system for helicopters
IPC: G05D1/08
Filed: 1963-02-18
Abstract: 984,986. Controlling helicopters. NORTH AMERICAN AVIATION Inc. Feb. 18, 1963 [Feb. 20, 1962], No. 6518/63. Heading B7G. [Also in Division G3] A servo operated actuator is disposed in the linkage connecting a pilot control to mechanism for controlling the attitude of a helicopter about an axis, and a signal representing rate of change of that attitude is applied to the actuator through a lag-lead signal shaping network the lead time constant of which is significantly less than the lag time constant, the lag signal being limited to a value less than that producing the full range of movement of the actuator. In the Figure, actuators 30, 31 which are variable length links, are disposed in the mechanical pitch and roll linkages, respectively, connecting a pilot's cyclic pitch column 32 to a conventional swash plate mechanism. Each actuator is energized by the output signal of a network 64, each network receiving the appropriate pitch or roll D.C. signal from a vertical sensor 63. The roll network also receives a heading error signal from a device 62. In the pitch channel, a trim signal is added from a manually set potentiometer 78, and the sum is passed to a differentiating or washout resistor-capacitor combination 67, 68. The output terminal 66 of the network is shunted to ground by a resistorcapacitor combination 69, 71, so that the output voltage is related to the rate of pitch by a transfer function (T 2 s + 1)/(T 1 s + 1) where s is the differentiate with respect to time operator, T 1  is at least ten seconds, and T 2  is at most one-sixth of T 1 . A switch 72 may be closed manually to add a pitch angle signal to output terminal 66 through summing resistor 70, so that the system then operates to maintain the helicopter at the trimmed pitch angle. The output of network 64 is limited by a diode device 44<SP>1</SP>. The control column 32 is connected to the airframe through a magnetic clutch 45 and preloaded double acting spring box 51, the preload force being greater than that required to operate the swash plate, so that operation of actuator 30 moves the swash plate rather than the control column. The actuator 30 has a smaller range of movement than the control column, so that when the actuator is fully extended, the pilot can still operate the swash plate. Closure of switch 49 on the control column releases clutch 45, thus trimming the zero feel position of the control column. The roll control system is similar. An actuator 61 in the linkage between pedals 60 and the antitorque tail rotor is energized by the heading error signal from device 62, through network 74 similar to network 64, to damp heading changes. In another embodiment, Fig. 4 (not shown) signals from pitch rate and roll rate gyros are passed through signal shaping networks having transfer functions as above, and energize actuators 30 and 31 respectively. Specification 970,454 is referred to.
