Patent GB-685911-A (GB)
Title: Improvements in or relating to a process for the production of artificial fibres
IPC: D01D5/08
Filed: 1947-07-15
Abstract: A fibre-forming mass in a thick or semi-solid state is applied to a support and is subjected to the picking-up and extending action of the tips or points of a finely pointed rotating member which by its rotation is periodically brought into contact with the support and withdrawn therefrom to produce artificial fibres of comparatively <PICT:0685911/IV (a)/1> short length.  The finely-pointed rotation member (or "gib") may be formed as a comb or brush.  Fibre may be produced from glass, polyamides, polyacrylates, polystyrenes, polyvinylchloride and cellulose esters.  If desired, the process may be carried out in a non-oxidizing medium, e.g. nitrogen or carbon dioxide.  As shown, the semi-solid fibre-forming mass is fed from a container 1 to a spreading plate 2 and thence to a roller 3 on which it is spread in a uniform layer.  Another cylinder 4 revolves on an axis 5 parallel to that of cylinder 3.  A comb 6 is mounted on a frame 7 provided with counterweights, the frame 7 being mounted for independent rotation on the axis 5 of the cylinder 4.  Preferably the comb rotates at a slower velocity than the cylinder 4, thus stretching the fibres.  The points of the comb strike the surface of the roller 3 during rotation and draw the material into fibres, which are deposited on roller 4 during further rotation of the comb.  If desired, the fibres may be entrained from the points of the comb by a current of air and deposited on an endless belt.  A steel wire brush may be used instead of the comb.

Title: Improvements in or relating to remote control and indicating systems for radio relay stations
IPC: H03G1/02
Filed: 1934-06-25
Abstract: 440,425. Electric signalling systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Electra House, Victoria Embankment, London.-(Assignees of Beverage, H. H.; Riverhead, Long Island, New York, U.S.A.) June 25, 1934, No. 18762. Convention date, June 23, 1933. [Class 40 (i)] [See also Group XL] A chain of radio relay stations is remotely controlled from a single point over an auxiliary channel over which two kinds of signal may be sent, the first of which selects an operation and the second controls the selected operation. At the controlling point positive current from a source 16 may be sent over the wire 18 by a key 11 or in the form of impulses by a dial 12 and negative current from a source 17 by a key 15. At each relay station two polarized relays 19, 20 respond to positive and negative currents respectively and close contacts 22, 23 and 24, 25 respectively. In order to start up the transmitter 63 at each station, " C " is dialled to rotate the step-by-step switch a to its contact C through the notching magnet 27 and then a negative current is sent over the line energizing the coil 56 of a polarized relay 65 through said contact C. This closes contacts 58, 59 energizing the power contacter 60 to connect transmitter 63 to its power supply PS. The contacts 58, 59 remain closed until winding 57 of the relay 65 is energized. The step-by-step switches a are returned to zero by sending a long positive current to energize the slow acting release magnet 32 and the transmitters are closed down by dialling "B" to prepare a circuit over the. contact B of switch a for a subsequent negative impulse to energize the winding 57 to open the contacts 58, 59. An alarm 54 may be operated by dialling "A" and sending a subsequent negative impulse. A selective operation may be performed at one station only by dialling the number of the required station (6 in the case case shown) in order to divert subsequent impulses from the switch a to the switch b, relay 42 being energized to change over the contact 48 from contact 49 to contact 50, at the selected station only. Subsequent impulses operate the switch b at the selected station to bring into operation an auxiliary transmitter 73 or perform other operations. Telemetering equipment may be provided, Figs. 2 and 3 (not shown), which is brought into operation from the control station to give indications of aerial current, received signal strength &c. by means of currents of different frequencies sent back over the line and controlled as to amplitude by the quantity to be measured. These are separated by filters, rectified and applied to current meters.

Title: Setting of justifiers in end-of-line justifying typewriters
IPC: B41J19/64
Filed: 1952-07-29
Abstract: 723,941. Typewriters. LEGLISE, P. July 29, 1952 [Aug. 28; 1951], No. 19129/52. Class 100(4). In end-of-line justifiers, e.g. of constructions described in Specifications 715,115 and 717,947 the desired amount of justification to which the justifier setting scale should be set is directly indicated on a letter-space scale e by an indicator i during the printing of a trial line, or by blank typing (i.e. tapping out the wording on the spacing key) the end part of the line in which justification is to be effected. The reading on the scale e is then used to set a justifying mechanism J to a corresponding marking on a scale E. In the embodiment shown, the scale e comprises a series of differently-coloured markings n on a clip C adjustable along a graduated paper bail R so that the central or zero marking registers with the indicator i fixed on the typewriter frame at the desired right hand end of 'the lines. For convenience the indicator may be formed with a second pointer i<SP>1</SP> so that a bail-roller r may take up or remain in a position best suited for controlling a paper sheet. A second indicator plate may be fitted on the right of the type-guide G. After the typing of the last letter in a predetermined unjustified terminal segment (end portion) of a line or after typing of a whole trial line, the amount of justification is seen on the scale, and the justifying mechanism J may then be readily set to a corresponding marking on the scale E. The commencement of the terminal segment is determined by adjustment of the stop k on the machine frame. The clip C comprises two hooks c, c<SP>1</SP> for engaging the bail R and the scale e passing behind the bail. Alternatively, the scale e may be formed in front of the bail on a horizontal part integral with two side-pieces similar to hooks c, c<SP>1</SP>. The clip may also be of the form shown in Fig. 7 and the markings n may be circular, eliptical, square, triangular, etc.; the marks on either side of the zero may be similar or different in shape. If it is required to have the scales numbered, the marks + 2, - 2 only are made. The scale e, alternatively, may be (a) permanently fixed on the bail R with the indicator i adjustable on the frame; (b) adjustably mounted on the frame with the indicator fixed on the carriage; or (c) fixed on the frame with the indicator adjustably mounted on the carriage. The justification mechanism J may be any of the forms described in Specification 715,115. Specification 723,942 relating to means for accelerating the blank typing also is referred to.
Patent GB-635635-A (GB)
Title: Manufacture of substituted mononitronaphthalenes and substituted monoaminonaphthalenes
Filed: 1947-07-17
Abstract: Mononitro - 1 - halogen - 2 - alkoxynaphthalenes are prepared by the treatment of a 1-halogen-2-alkoxynaphthalene with a nitrating agent consisting of nitric acid alone, and isolating at least one of the resulting isomers.  The halogen is e.g. chlorine and the alkoxy group e.g. methoxy or ethoxy.  For the nitration, nitric acid is used alone or mixed with an inert organic solvent, e.g. chlorobenzene. Temperatures in the range 10-80 DEG  C., particularly 40-60 DEG  C., are preferred.  The product consists of 6-, 8-, and 4-nitro-2-alkoxy-1-halogen-naphthalenes.  The 6-nitro compounds (particularly when the alkoxy group is methoxy) may be isolated by making use of their insolubility in boiling alcohol; with higher alkoxy groups, crystallization alternately from alcohol and carbon disulphide may be necessary.  The compounds may be separated by distillation, preferably in vacuo; further purification may be effected by crystallization from carbon disulphide.  In the examples: (1) powdered 1-chloro-2-methoxynaphthalene is added to nitric acid (62 per cent), the temperature being maintained at e.g. 40 DEG  C. by cooling, to yield on dilution with water a crude product which is extracted with boiling ethanol to leave a residue of 6-nitro-1-chloro-2-methoxynaphthalene.  The latter is reduced in alcohol with iron and a little acid to give 6-amino-1-chloro-2-methoxynaphthalene.  In example (2) a solution of 1 - chloro - 2 - methoxynaphthalene in chlorobenzene is nitrated at 40-60 DEG  C. and 6 - nitro - 1 - chloro - 2 - methoxynaphthalene isolated from the product.  The 2-ethoxy compound is prepared in a similar way, isolated by crystallization, and reduced to the 6-amino compound.  Example (3) is similar to example (2), but in addition to the isolation of the 6-nitro derivative, the more alcohol-soluble isomers are fractionally distilled in vacuo, and after a crystallization procedure, the 4-nitro and 8-nitro isomers are also obtained.  The latter 8-nitro isomer is reduced to the 8-amino compound; the 8-nitro-1-chloro-2-ethoxy-naphthalene may be prepared in a similar manner.  The Specification as open to inspection under Sect. 91 refers to the use of nitration agents in general.  This subject-matter does not appear in the Specification as accepted.

Abstract: 871,111. Annealing bell furnaces. STEIN & ATKINSON Ltd. June 18, 1957 [June 18, 1956], No. 19205/57. Classes 51 (1) and 51 (2). In a recirculating atmosphere furnace of the kind having a base supporting the charge, a removable inner cover, a fan in the base for circulating the atmosphere within the inner cover and an outer cover arranged to supply heat to the inner cover, radiant heat is concentrated on a limited zone of the inner cover. A portable heating hood 10 and inner belltype muffle 11 seat on a base 15 comprising a stand 18 for supporting a column of coils of metal to be annealed. The furnace atmosphere is circulated by fan 23 coaxial with a central aperture in the top plate of the stand 18, which has radial gas passages defined by spacers. The furnace is heated by tangentially directed burners 34 within a groove 35 in the peripheral wall 16 of the base 15, on which the hood 10 seats. An annular air supply passage 37 supplies air tangentially to the track 35. The track 35 may be of rectangular, curved or triangular cross-section or it may be formed below a projecting lip or ledge on the inside wall, but its radial depth should be at least half of its vertical height in order to concentrate the radiant heat on the lower part of the inner bell 11. Pilot burners may be arranged in a small annular recess within the track 35. Secondary air from passage 42 is supplied at low velocity through radial ports 43 below the hot track, and the proportion of secondary air supplied is controlled in accordance with the temperature at thermocouples 45 and 46 in the lower and upper parts of the bell 11 respectively. A higher proportion of secondary air raises the level of the hottest part of the bell. The total fuel and air input is controlled in accordance with the temperature at a third thermocouple 55 in the stand 18. A wall 60 close to but spaced from the side wall of the inner bell 11 forms a nozzle directing the gases against the side wall. A horizontal flange 62 at the bottom of wall 60, seats on the top plate of the stand 18, and vertical slots in the wall 60 enables the flange 62 to seat properly on different bases when the inner bell 11 seats on the base, Fig. 6. The wall 60 extends to the same height as the intense radiation from the hot track 35. The wall of the bell 11 may be corrugated. In a modification, Fig. 3 (not shown), the hot track 35 is formed in the'outer cover rather than in the base.
