Abstract: 1,200,813. Regulating fluid-flow. PERKINELMER CORP. Jan.9, 1968 [Jan. 9, 1967], No.1314/68. Heading G3H. [Also in Division B1] Apparatus for mixing two liquids, gases or vapours comprises a fluid-flow impedance network (as shown, a pneumatic network for mixing gases or vapours) having inlets 12, 14 to which the fluids are respectively supplied at regulated (and preferably equal) pressures and comprising flow restricting impedances 54 to 76 having outlets 36-44 and arranged so that a mixture of the two fluids is available from each outlet in concentration differing e.g. by a factor of 10. The impedances may be capillary tubes of differing lengths, or tubes packed with sand or glass beads. The outlets may selectively be coupled to the point of use by a manually operated rotary valve (46), see Figs.1 and 4 (not shown) or by an arrangement of vents and stop-cocks see Fig. 5 (not shown). Tubular mixing chambers (112), Fig.6 (not shown) may be introduced at the junctions of the impedances. The two fluids may be two streams of an inert carrier gas such as nitrogen or helium, one stream of which has been passed through a liquid to saturate it with vapour, see Fig. 4 (not shown). The apparatus may be used in the calibration and testing of gas chromatographs.

Abstract: 707,180. Correcting inductive disturbance. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Oct. 3, 1952 [Jan. 17, 1952], No. 1427/52. Class 40 (4)  Spurious signals due to induced currents in the screen of a cable feeding H.F. signals to an apparatus are reduced by connecting the screen to earth adjacent the apparatus through a resistance and employing voltages set up in this resistance to counteract the spurious signals. As shown, the normal terminating resistance 5 is connected in series with resistance 6, the condenser 7 providing a H.F. return path. Resistance 6 feeds transformer 9, one end of the secondary of which is connected to the cable side of condenser 4, while the adjustable tap of a potentiometer resistance 11 connected across the secondary is connected to the apparatus side. The arrangement is such that the compensating voltage derived from resistance 6 acts in opposition to the spurious components appearing across resistance 5, while potentiometer 11 provides for amplitude adjustment. Alternative embodiments are described in which the signals appearing across 5 and 6 are applied to one valve'and those appearing across 6 to another, the valves operating differentially to give a wanted-signal-only output.

Title: Improvements in devices for forming tabs in strips of adhesive tape
Inventor: BRITTON WILLIAM JOHN
IPC: B65H35/00
Filed: 1955-01-18
Abstract: 828,534. Adhesive tape dispensers. JOHNSON & JOHNSON. Jan. 9, 1956 [Jan. 18, 1955]., No. 1536/55. Class 18.  A device for forming tabs on adhesive tape comprises a roll support and fixed and moveable platforms 14, 15, the latter being biased towards the former, withdrawal of tape separating the platforms to which the tape adheres. On the tape being cut by a knife 16, the platforms are again brought together, forming a tab 29 by which the next length required may be grasped. As tape is withdrawn, it rotates a roller 8 geared to a spindle 10, the latter being spring biassed to rotate anti-clockwise (as shown), but being rotated clockwise by the roller 8. The platform 15 is mounted on an arm 17 connected by a rod 22 to a member 23 having a friction grip 25 on the spindle 10. Clockwise rotation of the spindle 10 causes the platforms to separate until the arm 17 contacts an adjustable stop 26. The grip 25 may then slip. When the tape is severed, the spindle 10 rotates anti-clockwise automatically to bring the platforms together. Means for limiting the amount of tape withdrawn is provided in the form of a dial, Fig. 1 (not shown) mounted disengageable on the spindle 10 and having a stop for contacting a fixed lug on the dispenser body. The dial may be disengaged from the spindle 10 and rotated to space its stop a predetermined peripheral distance from the lug and then re-engaged with the spindle. The spindle 10 may then be rotated by the drawing off of tape until the stop and lug contact each other.

Title: Diammonio esters
Filed: 1955-01-18
Abstract: The invention comprises compounds having the formula <FORM:0764141/IV(b)/1> wherein R and R1 are alike and are methyl or ethyl groups and X and X1 are stable nontoxic anions.  Such compounds are obtained by reacting a 2-haloethyl 3-halopropionate and dimethylethylamine or diethylmethylamine in the presence of a solvent, for example chloroform, dioxane or acetone, at a temperature between about 10 DEG  and 100 DEG  C. or by treating the appropriate di-(tertiaryamino) ester with a methyl or ethyl halide, and in the case where the non-toxic anion desired is other than halide substituting the desired anion for the halide ion. The substitution may be effected by treating the halide with the appropriate salt having a cation which yields an insoluble halide. Examples describe the preparation by such methods of various bromides, chlorides, iodides, and nitrates of the above formula. Nitrate ions may be substituted for iodide by treatment with silver nitrate.  Other anions may also be introduced by treatment with ionexchange resins. Further non-toxic anions mentioned are sulphate, phosphate, acetate, bitartrate, citrate, borate, formate, lactate, oxalate and propionate.  Starting materials.  2-Iodoethyl-3-iodopropionate is prepared by reacting 2-chlorethyl-3-chloropropionate with sodium iodide in methyl ethyl ketone.  The product, reacted with diethylamine, yields 2-diethylaminoethyl-3-diethylaminopropionate.

Title: Improvements in or relating to the production of potentially heat reactive thermosetting resins and to infusible resins and resinous products obtainable therefrom
IPC: C08G6/02
Filed: 1948-01-20
Abstract: Potentially heat reactive thermosetting resins are obtained from alkali-condensed furfuraldehyde-ketone condensates by heat polymerizing said condensates at a pH below 3.0, preferably in the range 0.5-1.5, and cooling the product while it is still in the heat reactive state.  Reduction of the pH is obtained by adding acids, e.g. nitric, sulphuric, chloracetic acids, or di-methyl or -ethyl sulphates, or by passing chlorine through the alkaline condensate. The fusible products are soluble in acetone, furfuraldehyde and alkyl acetates and may be further reacted with aldehydes or with other fusible resins, e.g. lignin, phenol-formaldehyde, cashew nut shell, or glyptal resins or shellac.  In the fully-cured state they may be ground and used with asbestos or rubber for brake and clutch linings. Examples describe the reaction first under alkaline conditions and then at a pH below 3 of furfuraldehyde with the following ketones-acetone, methylethyl ketone, methylisobutylketone, diacetone alcohol, isophorone, cyclohexanone, phorone, mesityl oxide, acetophenone, methyl n - amylketone, acetonylacetone, diethylketone, diisobutylketone.  In example (20) laminates are obtained from kraft paper soaked in a solution of the resin in ethyl acetate or acetone. In example (21) a moulding powder is obtained by hot milling wood flour, zinc oxide, iron oxide, hexa, catalysts and the resin. Emulsions are made (example 22) by mixing the resin with bentonite and water.
