Title: Rotary printing or coating machine
Inventor: NORRIS DONALD
IPC: B41F15/08
Filed: 1964-12-04
Abstract: 1,146,281. Stencilling apparatus. NORRIS-FROME Ltd. 4 March, 1966 [4 Dec., 1964], No. 49565/64. Heading B6C. A rotary printing or coating machine comprises a cylindrical perforated screen 13, a fluid container 19 inside the screen extending substantially the length of the screen, the fluid container being provided with means (e.g. pipes 28, 16 and apertures 30) for supplying fluid thereto, a fluid transfer roller, in the form of a hollow, flexible tube 33, partially filled with a loading material (e.g. mercury, lead shot or a liquid that may be pumped in and out to provide variable loading), extending substantially the length of the screen in free rolling contact with the inside of the screen and adapted to convey a thin film of fluid on its surface from container 19 to the inside of screen 13 and force the fluid through the perforations in the screen. The material to be printed or coated is brought into contact with the exterior of the screen, e.g. by resilient pad 35. Filters (32, Fig. 6, not shown) cover the apertures in the channel (31, Fig. 7, not shown) housing roller 33 by way of which fluid passes from container 19 to the roller. Roller 33 may have helical grooves on its surface. The screen is vertically adjustable to vary the printing pressure and may be of sheet metal, thermosetting or thermoplastic material or a knitted steel stocking electroplated to provide dimensional stability. As shown in Fig. 8 the above described machine 10 is used to print a number of spaced masses of thermosetting adhesive on a woven cloth 68 fed from a roll 60 (past vacuum slot 69 for cleaning) and these masses bond the cloth to a knitted cloth 70 fed from roll 72 with which it is brought into contact under a pressure roller 71. The adhesive may be cured by a heating roller situated between rollers 71 and 76 or by a heating roller 81. The cloth 68 is fed on travelling blanket 62 which blanket may be cooled by contact with band 65 passing over water cooled rollers 66 and 67. slots in the side walls by a pneumatic cylinder 10 and the rack 9 to deposit the counted batch of sheets on the underlying pairs of fingers 5. When a photo-electric sensing unit 19 detects the absence of a stack of sheets under the fingers 5 it causes a pneumatic cylinder 16 to actuate the rack 15 and pivot the fingers 5 in a manner similar to fingers 4, whereupon the pivotal outward movement of fingers 5 causes the batch of sheets to be deposited on a conveyer 3. Counted batches may be controlled by the height of the stack sensed by the sensing unit 19, which, also controls the movement of a conveyer 18 delivering the sheets to the receptacle and stops the conveyer when counted batches are deposited on both sets of fingers 4, 5 and a further counted batch is stacked below the fingers 5. In another embodiment (not shown) the pivotally mounted fingers may be replaced by slidable ones.

Title: Improvements in and relating to diorganotin derivatives of mercaptoacids
IPC: C08K5/58
Filed: 1965-12-02
Abstract: Diorganotin S, O mercaptocarboxylates are prepared by reacting R12SnO (R1 = saturated hydrocarbon radical) with a mixture of a mercaptocarboxylic acid HSCR2(CR2)nCOOH, and a thio-bis-carboxylic acid S(CR2(CR2)n COOH)2, wherein n is 0 to 2, and R is H or a saturated hydrocarbon radical, said mercaptocarboxylic acid being present in at least one mole per mole of R12SnO, and then removing the water which is also formed.  Preferably, n = 1 and the reaction is carried out in an inert solvent such as isopropyl ether.  The mixture of mercaptocarboxylic acid and thio-bis-carboxylic acid may be prepared by reacting a lactone of the Formula II <FORM:1084610/C2/1> or a halocarboxylic acid of the formula ClCR2(CR2)nCOOH with a water soluble in organic sulphide (preferably an alkali metal hydrosulphide) in a polar solvent, e.g. water at less than 30 DEG  C., and then ether extracted for reaction with the diorganotin oxide.  The process of the invention eliminates the need to purify the mercapto acid reactant.  In the example sodium hydrosulphide was allowed to react with b -propiolactone in aqueous solution at 10 DEG  C., the solution acidified, to a pH of less than 1 and extracted with isopropyl ether.  The ether extract contained 22% by weight b -mercaptopropionic acid and 4.5% b ,b 1-thio-bis-(propionic acid) and was then reacted with di-n-butyl tin oxide according to the process of the invention.

Title: Method of making biaxially oriented non-woven fabrics
IPC: D04H1/70
Filed: 1976-12-08
Abstract: An aqueous dispersion of long and short fibres is slurried by stripe-forming elements onto a moving endless wire. The long fibres have a minimum length of 12.7 mm. The short fibres are shorter than 12.7 mm. The stripe-forming elements extend in the direction of movement of the endless wire. They are either formed on the longitudinal wire itself by stripy liquid-impermeable coverings over the wire apertures or fixed in place as stripe-forming strips above the endless wire. The distance between the stripe-forming elements is less than the average length of the long fibres. The fibre web thus produced has successive alternating regions (11, 12) of higher and lower fibre density. The fibres in the regions (11) of higher fibre density are aligned in a parallel arrangement in the longitudinal direction of the fibre web. The fibres in the regions (12) of lower fibre density are aligned transversely to the longitudinal direction of the fibre web. The fibres in the stripe-structured fibre web are fixed, for example by applying an adhesive to the composite (10) or, if thermoplastifiable fibres are present, by heating the composite (10). <IMAGE>

Abstract: 1400669 Analyzing engine exhaust gases FORD MOTOR CO Ltd 7 Nov 1973 [5 Dec 1972] 51602/73 Heading G1B An apparatus for making a fuel-based determination of the total gaseous constituents emitted from an engine comprises (a) a through-flow duct effective to directly receive the emissions from said engine and to provide homogeneous mixing therein, (b) means effective to continuously and isokinetically extract a gas sample of said homogeneously mixed emissions from said duct, (c) a receptacle for collecting said gas sample transmitted by said extracting means, and (d) means for maintaining the temperature of said emissions in the receptacle and in said extracting means at an elevated uniform temperature to prevent condensation of said emissions. An apparatus of the type described above is illustrated in the accompanying drawing. In this apparatus, exhaust gas emissions from an engine are received by duct A, this duct containing a mixing device 10 to homogenize the emissions. A sample of these emissions is extracted by isokinetic probe 13 and passed via container 15 and pump means 17 to collection receptacle 16: A means C is employed to obtain equalization of the pressure at the exit of duct A and at a downstream station 23 of said probe 13. A heating apparatus 25 is provided surrounding the probe 13 and enclosure 24, to prevent condensation. During operation, as the bag 15 expands to eventually adopt the shape of enclosure 24, transducer 18 senses a pressure difference between exit 22 and station 23, and pump means 17 is activated to reduce the pressure in bag 15 and restore isokinetic pressure conditions. Alternatively, these conditions may be restored by means of pump 17, said pump being activated by a micro-switch on the interior of enclosure 24.
