Title: Process of degumming silk
IPC: D06C15/00
Filed: 1930-02-03
Abstract: 349,961. Degumming silk. JACKSON, L. MELLERSH-, 28, Southampton Buildings, Chancery Lane, London.-(Twitchell Process Co. ; June Street, Cincinnati, Ohio, U.S.A.) Feb. 3, 1930, No. 3630. [Class 120 (i).] Natural silk is degummed by treating with an alkaline solution of a mineral oil sulphonate, preferably mahogany sulphonate. Subsequent dyeing operations are facilitated by the fact that both the mahogany soap and the mahogany acid to which it is converted by the acid dye bath are soluble, uneven dyeing thus being avoided. In an example, silk is immersed for 10 to 45 minutes in a solution containing À03 per cent sodium hydroxide and À5 to 1 per cent sodium mahogany sulphonate at a temperature slightly below boiling point. To prevent salting out, and to obtain a homogeneous solution, a small amount of a water soluble solvent, e.g. À08 per cent of 95 per cent methyl alcohol, is added to the solution. Specification 127,159, [Class 91, Oils &c.], is referred to.

Title: A method of and an apparatus for selectively remotely controlling receivers
IPC: H02J13/00
Filed: 1969-01-23
Abstract: 1,253,733. Electric selective signalling. ZELLWEGER Ltd.. 23 Jan., 1969 [12 Feb., 1968], No. 3769/69. Heading G4H. In a remote control system of the kind in which a sequence of pulses is transmitted over power lines to effect a control at a receiver, a signal for controlling an individual device consists of a combination of m of the available n bits, and a master control for simultaneously controlling all the devices of a group consists of combination of p of the available n bits. As described n = 5 and each receiver monitors three of the five bits. In the form of Fig. 1 an individual control signal consists of three "1's" and two "0's". For example in line 1, the individual control signal is 00111. One device is adapted to respond to 00XX1, the positions shown by X being unmonitored. This signal is shown in line 1, column C. Columns D and E show other monitored patterns, the signal 00111 serving also to operate the corresponding devices. A master control signal, has one "1" and four "0's". That in line 0 column C is 00001 and this operates all the devices whose monitored patterns are shown in column C. Similarly the master signal 12 operates all the devices in column D. Each receiver consists of a codedgap switch rotated by a synchronous motor so as to connect to a contact 44, Fig. 3, or contact 46. The switch 34 is operated by the incoming pulse sequence, to switch between contacts 35 and 36. If the sequence of pulses is correct, the switches 34 and 43 never make a common connection to short circuit a switching element 63. The switching element remains conducting and near the end of the cycle, contact 50 closes to apply a control signal to terminal 72. The contact discs of the coded-gap switches may be changed to change the pulse sequence to which a receiver will respond. Instead of using binary valued bits, the "1" and "0" may be signalled by pulses in either of two time positions in each bit slot.

Title: Improvements in radio beacons
IPC: G01S1/02
Filed: 1937-02-09
Abstract: 491,963. Directive wireless systems. SOC. ANON. DES ONDES DIRICEES. Feb. 9, 1937, No. 3862. Convention date, Feb. 14, 1936. [Class 40 (v)] A rotating-beam effect is produced by radiating a carrier-wave of constant average amplitude but supplied with a modulation note which varies with the azimuth and with time. Two fields are radiated at the same frequency, one modulated and the other not, the phase of one field varying with the azimuth, and the other with time, the " zero " modulation of the field rotating with constant angular velocity. For instance in Fig. 1, one pair of aerials A1, A2 is energized in phase-opposition, whilst another pair of aerials A<1>1, A<1>2 is energized in quadrature, the resultant field being of constant intensity, but with a phase-variation in azimuth. Another aerial B, situated at the centre of the system, is energized with current of the same frequency, but modulated at a lower frequency. An observer at a point M<1>, by observing the time which elapses between the receipt of a signal indicating the beginning of the rotation, and the instant when the " zero " modulation sweeps past him, can ascertain his bearings relatively to the transmitter. The aerials A1, A2 and All, A12, Fig. 7, are fed from a source 1 through stationary coils 2, 3, whilst a rotating coil 4 feeds the aerial B with a voltage which varies in phase with time. The voltage is fed in parallel to the grids of two pentodes 5, 6, the outputs being coupled in opposition to the aerial B. The modulating note is applied through a rotary switch 8 which makes first one pentode and then the other operative in feeding highfrequency current to the aerial. The direction of the nodal line of radiation is controlled by the coil 4, which can, if desired, be " locked " at a given position to produce a stationary " guiding line, the outer margins of which are distinguished by complementary Morse signals, such as " A " and " N ". Specifications 271,508 and 273,754, [both in Class 40 (v)], are referred to.

Abstract: 104,739. Craddock, T. F., (Craven, A., and Burn & Co.). March 16, 1916. Combined buffer and draw-gear. - Relates to arrangements in which the buffer-head and the shank or draw-bar are separable and are capable of pivotal movement in relation to each other when in use. The end of the shank B is formed as a vertically-disposed T-head B<1> adapted to rock on a 'bearing at the back of the. buffer-head A. In one construction, Figs. 1 and 2, the head B<1> bears against the forward face of a renewable bush N fixed in the buffer-head. The vertical sides of the hole in the bush are tapered as shown in Fig. 2, to allow for the rocking movement, and the top and bottom faces of the shank are tapered as shown in Fig. 1, to fit a corresponding tapering of the hole in the bush. A bolt D prevents forward displacement of the shank. In a modification, Figs. 6 and 7, the bush N is dispensed with, and renewable key-pieces O<4>, O<5>, shaped as shown to fit the correspondingly-shaped shank, provide those portions of the T-head which take the wear. Similar key-pieces may be used in the case of a shank B of triangular cross-section. In another arrangement, the contacting surfaces of the shank and of the hole in the bush, or in the buffer-head when the bush is dispensed with, are curved, and clearances are provided. Fig. 8 shows a modification in which clearances for vertical, as well as for horizontal, movement are provided. In a further modification, Fig. 11, the T-head formed by renewable key-pieces B<2> bears against a renewable plate N'.

Abstract: 1,212,593. Jet propulsion plant; turbines. BRITISH AIRCRAFT CORP. Ltd. Jan. 14, 1969 [Jan. 25, 1968], No.3954/68. Headings F1J and F1T. [Also in Division F2] A seal between two coaxial parts, one being stationary and the other rotatable (e.g. a seal for preventing the escape of gas through a gap 15 in a gas turbine jet propulsion engine) comprises an inwardly-facing channel 6 on the stationary part, a flange 13 on the rotatable part extending normal to the axis of rotation and into the channel, a container 7 including a heater 12 for supplying the metal gallium 14 in a liquid state to the channel at a point 9 closer to the rotational axis than the outer diameter of the flange, and means 10 for applying pressure to the container upon rotation of the parts so that upon rotation some of the liquid is expelled into the channel and on stopping the rotation the expelled liquid is returned into the container. The gap 15 is between the combustion chambers 5 and a rotary shroud 2a carrying ducted fan blades 1. Before the engine is started the heater 12 is used to melt the metal. The engine is then rotated and-pressure is transmitted to the container 7 via the duct 10 to transfer the liquid metal 14 by way of a duct 8 into the channel 6 where it is centrifuged to take up the position shown in Fig. 2. As the engine speed increases the gas pressure at the gap 15 displaces the level of the metal in one of the legs of the channel as shown in Fig. 1A such that the centrifugal force exerted by the displaced metal balances the pressure exerted by the gas. Following engine shut down, the metal returns to the container 7 via mouth 9 and duct 8 to solidify. Blades 13a, 13b or scollops may be provided on the flanks of the flange 13 and retaining lips 6a, 6b may be provided on the channel. The forces acting axially on the flange 13 due to unequal levels in the channel during operation are opposed to the thrust of the fan blades 1.

Abstract: 1,083,622. Stapling and nailing machines. JOH-FRIEDRICH BEHRENS. Jan. 28, 1966 [Feb. 24, 1965], No. 3967/66. Heading B4C. A pneumatically-operated stapling or nailing machine comprises a driving piston 80 reciprocably mounted in a cylinder 60 under the control of valve means 30 which is adapted to permit the pressurized air to exert an initial driving pressure on the piston after closure of all outlet openings on the driving side of the piston. The valve means is in two parts 31, 32, the part 31 having a piston portion 45 and a face 42 arranged to co-operate with a sealing ring 39 secured to the part 32, the latter part having a piston portion 34 and a face 36 arranged to contact a sealing ring 56 in an insert 27. The piston 80 is provided with resilient ring 86 adapted to contact a sealing member 70 at the end of the working stroke. In operation, with a trigger-actuated valve 90 open as shown, air flows via a passage 92 so as to act on the piston 45 and maintain the valve means in a position in which an outlet passage 50, 51 is open to atmosphere. Upon depressing the trigger, the valve 90 is closed and the air then acting on the piston 34 via a passage 93 urges the valve part 32 downwardly so that the face 36 contacts the sealing ring 56 and thereby closes the outlet. The compressed air then acts on the surface 42 thereby separating it from the sealing ring 39 so that the air acts on the top of the driving piston to move it on its driving stroke; the air ahead of the piston is exhausted to atmosphere through ports 73 in the sealing member 70 and a passage 25. At the end of the stroke, the ring 86 abuts the sealing member so as to close the ports 73 and the head of the piston is positioned so as to allow compressed air to enter a chamber 59 via ports 64 in the cylinder. When the trigger is released and the valve 90 opened, the valve means 31, 32 is returned to the position shown and the piston returned by the air trapped in the chamber 59. The piston is retained in the upper position by means of a magnet 57.
