Patent GB-103249-A (GB)
Title: Improvements in and relating to Recording and Reproducing Sound.
Inventor: MURRAY WALTER JOHN
Filed: 1916-06-06
Abstract: 103,249. Murray, W. J. June. 6, 1916. Speed, regulating and indicating.-The range of graduation for the speed-regulating spindle of gramophones &c. is extended by providing two dials, one of which indicates the angular position of the speed-regulating spindle, the other showing the number of complete revolutions thereof; and each record is marked with two numbers, one indicating the reading of the regulator when the record was taken, and the other showing the regulator reading when the recording-machine is run at such a speed as to cause a standard singletone record to give its correct note. The motor speed is adjusted by the axial movement of a spindle 7 having a threaded portion 6 engaging a fixed internal thread 5. A square portion 8 of the spindle carries a boss 9 with a pointer 10 moving over a fixed dial 3, and also carries a disk 12 having a single tooth which, after each complete revolution, moves forward a pinion 14 and a numbered disk 15, the numbers thus being successively visible through an opening 16 in the case. A. spring bearing on the smooth or notched rim of the disk 15 prevents accidental movement When a song &c. is to be recorded, a standard single-tone record is placed on the recording- machine, and the speed is regulated until the record gives its correct note, say la, with a speed indication, say 3.10. The song is then recorded at a suitable speed, say 3.50, and the record and all copies taken from it are stamped " la 3.10, sung 3.50." In order to reproduce at the correct speed, a standard single-tone record is placed on the reproducing-machine, and the speed indication, say 2.90, required to give off the correct note is read. By comparison with the stamping on the record to be played, it is seen that the reproducing-machine gives an indication 20 below that of the recording-machine, and the record when played with the regulator set to 3.30, reproduces the song at the pitch at which it was originally sung. The standard record may also be used for correcting the speed-indicating scale of the reproducing-machine.

Title: Improvements relating to the production of paraformaldehyde
IPC: C08G2/08
Filed: 1932-03-21
Abstract: Paraformaldehyde in a form which readily dissolves on heating with water is obtained by removing water from aqueous solutions of formaldehyde by distillation with organic liquids capable of producing with water azeotropic mixtures of low boiling point. The auxiliary liquid may, for example, be toluene, ethyl acetate, methyl ethyl ketone, diethyl formal, mesityl oxide, or ethylene dichloride; or the water may be removed in a ternary mixture by the simultaneous use of, for example, ethyl alcohol and diethyl formal.  In the example, 1000 gms. of ethyl acetate are heated in a flask provided with a tall Raschig column.  At a point two-thirds of the way up the column, a 40 per cent by volume solution of formaldehyde is run in at such a speed that the quantity of formaldehyde solution added agrees approximately with the quantity of water distilling off.  The azeotropic mixture passing off at 70 DEG  C. condenses to a mixture of 91,4 per cent of ethyl acetate and 8,6 per cent of weak formaldehyde solution. Paraformaldehyde separates in the flask, and by filtration and drying for a short time at 100 DEG  C., may be freed from adhering solvent.ALSO:Paraformaldehyde in a form which readily dissolves on heating with water is obtained by removing water from aqueous solutions of formaldehyde by distillation with organic liquids capable of producing with water azeotropic mixtures of low boiling point.

Title: Improvements in and relating to manufacture of valves in paper sacks
IPC: B31B19/84
Filed: 1931-03-20
Abstract: 362,807. Forming valves in paper bags. HOOVER, G. S., Wellsburg, West Virginia, U.S.A. March 20, 1931, No. 8681. [Class 94 (ii).] In making a paper bag, a cut in the side of a continuously moving bag tube actuates a device for folding in the side of the tube to form a valve. A continuously moving paper web, formed into a tube with pleated sides, surrounds a fixed hollow member 15, Fig. 1, which is formed at its free end with a head 16 having a lateral projection 17. The projection 17 has a V-shaped edge 18, Fig. 5, adapted to engage one pleat in the tube and the opposite pleat is held by a spring-pressed member 22 on the head 16. The head 16 lies between feed rollers 5 and more slowly moving rollers 6 and the former have rubber-covered portions 8 and wooden portions 11, a Z-shaped knife 9 on the last roller 5 making a cut 45 on the edge portion of the tube. A bar 26, normally held in a retracted position by a weight 29, slides in the hollow member 15 and carries at its outer end a rack bar 32 and intermediately a projection adapted to engage a depending arm secured to a rock shaft 61, the rock shaft being provided with a second depending arm which engages a rod 67 slidable in brackets 68 on the machine frame 1. A slide block 46 movable in a guide 47 is secured to the end of the rod 67 and carries a bifurcated finger 44 pressed by a spring 51 against the edge of the tube. The head of the slide enters the pleat in the tube, which is opened by a lug 56 on the head, and is formed with a right-angled recess 53. As the tube passes along the machine, arms about the projection 17 expand the tube and the finger 44 engages its edge until the cut 45 allows the spring 51 to press it inwards to fold the edge inwards against a former 33 forming a continuation of the projection 17 and secured to the rack bar 32. The former 33 has diverging horns 35 between which the tube edge is folded. On the head 16 of the member 15 is a curved pivoted arm 39 carrying a roller 40 adapted to press outwardly on the tube edge, until the cut portion reaches it and causes it to rotate, the rotation operating through a train of pinions to displace the rack bar 32 relatively to the head 16. The movement of the rack 32 and bar 26 draws the slide 46 along the guide 47 in unison with the former 33, and the arm 39 tucks down the cut edge of the tube between the horns 35 of the former 33, doubling the edge into the recess 53 in the slide 46. Converging arms 71 collapse the tube after the formation of the valve and an idler pinion ensures the re-formation of the pleat. A knife 13 on the last roller 6 severs the bag length from the tube, the ends of the length being subsequently closed by binding strips, one of which is doubled around the corner left by the cut 45, sewn thereon.
