Title: Improvements in making solutions of cellulose in sulphuric acid
IPC: C08B1/00
Filed: 1937-06-15
Abstract: Cellulose material in a wet or moist condition is mixed with sulphuric acid so as to produce a solution from which threads, bristles, ribbons, films, or like materials may be obtained.  The cellulose material may be in the form of a wet pulp such as is obtained in the disintegration of wood and the necessary purification and bleaching processes in making paper pulp, and it may contain 50 per cent or more of water.  The content of water may even be several times the dry weight of the cellulose. Preferably, the wet cellulose is uniformly distributed in several times its weight of dilute sulphuric acid, the concentration of which after dilution by the water in the cellulose, is about 52-57 per cent.  Mixing is preferably conducted at low temperature, and the wet cellulose may be used in a cool or frozen condition. Strong sulphuric acid is added to the suspension until the cellulose is dissolved.  In an example cellulose material containing 50 per cent of water is mixed at low temperature with a 58 per cent solution of sulphuric acid so as to form a suspension of cellulose in a 53 per cent solution of sulphuric acid.  To the suspension there is added at -3 DEG  C. an amount of 80 per cent sulphuric acid so that the cellulose is dissolved in a 63 per cent solution of sulphuric acid.  The solution may be spun immediately or after dilution with dilute sulphuric acid.

Patent GB-704313-A (GB)
Title: Television system
IPC: H04N1/00
Filed: 1952-07-03
Abstract: 704,313. Television. HAMMOND, J. H. July 3, 1952, No. 16791/52. Class 40 (3) A television transmitting system is arranged whereby the normal programme may be interrupted briefly to enable a still picture, consisting, for example, of a news sheet, to be televised, a control signal indicating that this is to occur being transmitted in advance. At a receiver, the control signal operates a recorder through a timing mechanism whereby a record is made at the instant the still picture is received. In the embodiment described, the transmitting station, Fig. 1 (not shown) includes a switch whereby the output from a camera viewing the still picture may be connected to the transmitter in place of the normal studio cameras. Upon operation of the switch a motor driven cam switch is set into rotation first to apply an audio tone to the sound channel as the control signal and then to apply the camera output to the vision channel. Thereafter the cam switch comes to rest and normal transmission may be resumed. At a receiver, Fig. 2, the control signal is selected by control mechanism 47 and applied through a thermally operated or dash-pot controlled switch to actuate the shutter 59 of a camera 48 viewing the receiver cathode-ray tube 42 at the instant the still picture is reproduced. Simultaneously a solenoid 62 is energized and withdraws a spring- loaded plunger 69 from engagement with a stop 68 to allow a cam switch 65 to commence rotation. After a short interval, contacts 76 are bridged by segment 66 causing a motor 75 actuating a film drive mechanism 77, 78 to be energized briefly. This results in the exposed portion of the film 82 being pulled into a processing chamber 85 where it remains until the contacts 76 are again bridged by a second segment 67. The exposed and processed film is then moved to frame 87 where it is projected on to a viewing screen 54 by lamp 89 and optical system 53, 91. Alternatively the projecting system may be dispensed with and the processed film may be viewed directly or torn off and used as a sheet for distribution. As a further feature the video signals may be recorded magnetically or as a charge pattern so as to permit reproduction whenever desired. The control signal may be sent over the video channel.

Abstract: 777,257. Trueing grinding wheels. NAGY, A. May 16, 1955 [June 9, 1954], No. 16942/54. Class 60 A diamond tipped tool for trueing and dressing a grinding wheel 1 includes indexing mechanism for presenting the diamond to the work in successive positions all of which are at or in close proximity to its directions of hard grain. The diamond 2 may be pyramid shaped and to reduce the tendency for large flats to be produced it is preferably indexed to an even number of unequally spaced indexing positions comprising four groups each of which consists of two or more indexing positions disposed symmetrically in relation to one of the directions of maximum hardness and disposed not more than about 15 degrees from such direction. A bit 5 holds the diamond in a sintered matrix 4 and is fixed by a grub screw 7 to a ratchet member 6 having notches 11 which correspond to the indexing positions and co-operate with a spring-loaded detent 9 connected by a pin 15 to a shank 14. A pair of springs 13 act as a clutch between the member 6 and a nut 12 threaded on to the head 8. When the cap nut 12 is turned in one direction it causes the member 6 to rotate with it until the detent 9 engages the next notch 11 while the springs 13 allow it to slip with respect to the member 6 on rotation in the reverse direction. A centre mark 16 serves to locate the tool correctly on a grinding machine. The diamond may be a rough diamond or one with a number of pyramids as described in Specification 655,720.
