Patent GB-454504-A (GB)
Title: Method of treating pectin
IPC: C08B37/00
Filed: 1935-03-29
Abstract: The intrinsic setting time of pectin is altered by treating solid pectin with an acidic reagent for a period insufficient to destroy the gel-forming capacity of the pectin.  The reagent may be an acid, an acidic substance, or an acid-forming substance, and may be liquid or gaseous, aqueous or anhydrous, but any carrier for the reagent should not dissolve or disperse the pectin. Suitable acid reagents are hydrochloric, sulphuric, sulphurous, phosphoric, nitric or lactic acids, chlorine, hydrogen chloride, hydrogen sulphide, sulphur dioxide, sulphur trioxide, or acid methyl sulphate.  Carriers which may be used are alcohols, glycols, ethers, ketones, acetyl chloride, ethyl acetate, acid methyl sulphate, aldehydes, amines, aliphatic or aromatic hydrocarbons, or air or other gases.  Usually the setting time is increased, but with anhydrous methyl alcohol as carrier, the setting time is shortened.  It is sufficient to store pectin containing residual acid and from 2 to 10 per cent of water to change the setting time.  Increase of temperature or acid concentration shortens the necessary period of treatment.  To stop the treatment and stabilize the pectin, it is washed with alcohol or other liquid, which may contain a buffer substance, and dried. Specification 239,635, [Class 121], is referred to.

Filed: 1941-08-05
Abstract: 552,335. Printing-machines. STEVENS, A. H. (Miller Printing Machinery Co.). Aug. 5 1941 No. 9938. [Class 100 (ii)] A two-revolution flat bed printing-machine in which the bed 17 reciprocates on four trackways 18 arranged between side frames, 10, 11 and supported by a cross beam 19 is driven by a motor 27 driving a sprocket 29 on a shaft 30 formed with a gear 32 arranged outside the frame 11 and adapted to drive a main shaft 44 on which is splined a gear 53 engaging a a central rack 56 on the bed for driving the bed at uniform speed during the printing operation. The shaft 44 drives the impression cylinder by means of a pair of gears 43, 45 and also drives a pair of crankshafts 34, 47 adapted to reverse the bed by cooperation with a central hanger 40 carried by the bed. The hanger 40 is formed with surfaces 41, 42 each arranged at an angle of 45 degrees to the machine base, and rollers 38, 52 of the crank pins 38, 51 first engage the lower edges of the surfaces 41, 42 to stop the motion of the bed, and in the case of the roller 38 further clockwise movement causes pressure of the roller on the upper side of the surface 41 and starts movement of the bed towards the left. The gear 53 is moved out of engagement with rack 56 by means of a cam 69, Fig. 3, which actuates a shifteryoke 70 provided with a block engaging a groove in a collar 61 on a gear 60 which is made to engage a rack 62 during the non-printing motion of the bed, the yoke 70 being linked to a similar yoke 74 which moves the gear 53 out of engagement with the rack 56. The shaft 65 of cam 68 is driven from the shaft 44 and is geared to a control shaft for a suction feed device, and is also fitted with a cam which oscillates a segmental gear 83 geared to an eccentric 87 connected by a push rod 88 to the eccentric bearings of the impression cylinder 14. The reversing rack 62 is arranged between the central rack 56 and a driving- rack 25a for the inking-apparatus, and this arrangement is adapted to prevent skewing of the bed upon reversal. The construction is adapted to shorten the span of the bed between the inner tracks 18 and to limit the deflection of the bed during printing. Also the location of the reversing gears beyond the side frame enables larger gears to be used which may be made of cast iron. The main driving-gears may be of single or double helical type, and may be enclosed in an oil casing. Specification 552,361 is referred to.

For making fine screws, particularly for the manufacture of diffraction gratings, a diamondholder or other tool-holder 13 is fed by a nut 7 which is mounted on a rotary cylinder 1 carrying a preformed master thread and is lined with flexible material, preferably cork in segmental strips 7<SP>1</SP>, so that errors in the master thread are averaged out in the thread cut by the tool. The cylinder 1 is mounted in bearings 2, 5 having segmental lining strips of cork or other resilient material and, at one end, has a thread 4 of zero pitch so that it is axially restrained as a whole but is free to expand. The tool-holder may be mounted on the nut 7 and close to it so that the tool cuts a thread on the cylinder 1 and, as the nut advances, it engages the improved thread which it itself has cut and which feeds the tool for further cutting. Alternatively, as shown, the thread may be cut on a second cylinder 6, similarly mounted to the first cylinder and driving it through reduction gearing 17. The tool-holder 13 is mounted on a second nut 8, which has a flexible lining 8<SP>1</SP> and is connected by an arm 12 to the nut 7 and, after a certain amount of thread has been cut, the secondary nut is released from the first nut by disengaging a catch 18, the gears 17 are disengaged and the tool is fed by the engagement of the second nut with the thread already cut. Out-riggers 9 riding on flat surfaces 10 prevent rotation of the nuts and the tool-holder 13 is mounted on flat springs 14 and damped by an oil dash-pot 15. A second tool may be mounted behind the nut for clearing or modifying the thread. The secondary thread may be similarly transferred to a third cylinder connected to the secondary cylinder by 1 : 1 gearing, either simultaneously or, preferably, subsequently. It is stated that it is known to cut an improved thread in a cylinder by means of a diamond or other tool supported at a distance from a cork-lined nut which is clamped on a master thread on the cylinder or by means of a tool supported between a pair of cork-lined nuts each engaging a portion of master thread near the ends of the cylinder.
