Title: Improvements in or relating to front feed devices for business writing machines
IPC: B41J11/54
Filed: 1953-08-04
Abstract: 748,660. Typewriters &c. TORPEDOWERKE AKT.-GES. FAHRRADER UND SCHREIBMASCHINEN. Aug. 4, 1953 [Aug. 16, 1952], No. 21525/53. Class 100 (4). In a front-feed device for a business writing machine of the kind wherein a feeler locates a punched hole in the card to arrest it in desired position for printing, the feeler 13 is forced by a spring 41 to follow the movement of the hole in the card, by the drive of draw-in rollers 16, 18. These rollers are driven by a hand lever and are coupled to a spring motor so that, after printing, the cards may be ejected. Rotation of rollers 16, 18 also rotates a cam which moves a bar 24 in the direction of the arrow shown and lifts a control member 33. This allows counter-clockwise rotation of an intermediate lever 43 so that the force of the spring 41, normally resisted by a flange 47 on the lever 43, is taken by the feeler 13 which enters a punched hole in the card and is urged positively along with the card. A nose 30 on the feeler mounting then engages an end 31 on a pivotal pawl 22 which engages a ratchet wheel 20 associated with the feeding roller 16 and arrests feeding. Upon the operation of a release key the rollers eject the card and bar 24 returns to position shown permitting return of control member 33 and intermediate lever 43, and a spring 27 returns feeler 13. A second card may be controlled by a feeler 13A, pawl 23, and an intermediate lever 49 connected to the first device by a link 50. When not required the device may be rendered inoperative by shifting the control lever 33 so that a notch 36 engages a rod 28.

Title: Improvements in and relating to devices for turning sheets of music and the like
IPC: B42D9/08
Filed: 1921-08-13
Abstract: 185,611. Semley, G. B. Aug. 13, 1921. Leaf-turners for music. Counterweighted turning arms 1 are released in succession. The arms are mounted to swing in front of the music R of a piano, music-stand, &c., and are pivoted at 8 to a bracket plate 2 carried by a stationary block 3 secured to the top of the piano &c. A slidable block 6, connected to the block 3 by a keyway 5 and dovetail rib 7, is moved rearwardly step by step to release the turning-arms in succession by means of a slide rod 23 with ratchet teeth 21 which are acted on through connections 24, 26, 27 from a pedal 28. In using the apparatus the turning-arms are disposed between the leaves of the music with their upper ends locked in inactive vertical position by a series of latch bars 12, which are pvioted at 13 to the part 3 and are provided each with a tail 16. The underside of each bar 12 has an arcuate groove which fits against a curved part 14 of the corresponding turning-arm 1. Each successive rearward movement of the block 6 under the influence of the pedal 28 exposes a latch bar 12, which is deflected to release the turning-arm by a cam action on the tail 16 of a finger 18 on the block 6. The tnrning-frame is thus moved out of the vertical and completes its movement under gravity.

Ultramarine is added to the acid solution before injection into the installations.
Patent GB-387004-A (GB)
Title: Improvements in the manufacture and treatment of staple fibre
IPC: D06M13/207
Filed: 1931-07-29
Abstract: Filaments of cellulose acetate or other artificial material are treated with bodies of a hygroscopic character and cut into stable fibres, continuously with their production.  The filaments may, if desired, be cut while still wet with the liquid containing the hygroscopic body.  The small amount of hygroscopic material on the fibres overcomes difficulty due to electrification of the fibres, and to the slipping of the fibres over each other during spinning.  As hygroscopic bodies there are mentioned ammonium citrate, magnesium chloride and the chlorides of calcium, zinc, iron, and strontium; the nitrates of magnesium, calcium, zinc, iron, cobalt, and nickel; the acetates and formates of ammonium, sodium, and potassium; sodium and ammonium phosphates; amines and amides and their salts, e.g. acetamide and methylamine hydrochloride; and quaternary ammonium compounds and their salts. Hygroscopic liquids such as glycerol, glycol, and diethylene glycol may be added to the solutions.  The hygroscopic body, in an example, is applied in solution of 0,1 to 0,75 per cent concentration.  The friction between the fibres may be further increased by applying, conjointly with or separately from the hygroscopic bodies, roughening media such as silica, barytes, lithopone, kieselguhr, or the soluble salts of Specification 372,797, and also, if desired, lubricants, e.g. olive oil.  When the fibres are cut wet, they may be dried in any suitable manner, preceded, if required, by a centrifuging operation to bring the liquid content down to about 30-40 per cent.  The staple fibres may be spun alone or in admixture with fibres of cotton, silk, wool, or reconstituted cellulose, such as viscose. Specifications 317,026, [Class 120 (iii), Yarns &c.], and 359,511, [Group IX], also are referred to.

Title: Improvements in or relating to ultra short wave radio antennas
IPC: H01Q9/43
Filed: 1947-08-07
Abstract: 658,612. Aerials. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Aug. 7, 1947, No. 21665. Convention date, Jan. 9, 1946. [Class 40 (vii)] A short-wave radio antenna, Fig. 1, comprises a conductor 60 bent in the form of a half loop having a semi-circumference of one half of the operating wavelength. One end 61 is connected to a conduction ground sheet 58, which may be the surface of an aircraft, and the other end is energized from a coaxial line TL, the outer sheath of which is connected to the ground sheet. The antenna has a maximum of radiation in the direction indicated by arrow F. In a modification, Fig. 2 (not shown), providing increased band-width, the coaxial line passes through and extends above the ground sheet for one-eighth of a wavelength. In a further modification, Fig. 3, the conductor 60 is hollow for a distance of one-quarter wavelength and a supplemental conductor 62 concentrically arranged within the hollow portion is connected to the ground plane. This places a quarter wavelength section of line in shunt with the antenna to act as a compensation circuit and broaden the band. In the antenna shown in Fig. 4, the semi-circular conductor 90 has an overall length of one-quarter wavelength and is hollow throughout. An extension 63 of the inner conductor 11 of the coaxial line TL provides a compensation circuit to widen the band. The Specification as open to inspection under Sect. 91 comprises also a further feed system, Fig. 10, (Cancelled), in which the effective feed point is shifted to point 100 by means of a supplemental sleeve 92. Fig. 2, (Cancelled), shows an antenna comprised of a whole loop having a circumference of 2#. The loop is supported horizontally a quarter wavelength above a metallic ground plane 18 by conductive supports 20, 22, and is energized from coaxial line TL which is bent round to form half of the loop. Fig. 5, (Cancelled), shows a.broadband whole-loop antenna formed of two cones 45, 46 energized at gap 47 by coaxial line TL. Fig. 3, (Cancelled, not shown), shows two horizontal loops each having a circumference of 2# A and spaced - vertically on a two-wire trans- 4 mission line. The feed points of the loops are also displaced by 45 degrees. Loops having a circumference of 1# and a feed point displacement of 90 degrees may be used. Fig. 4, (Cancelled, not shown), shows a modified feed system for a whole-loop antenna in which the gap in the loop is moved round so that the two parts of the loop differ in length by an odd multiple of A -. This subject-matter does not appear in the 2 Specification as accepted.
