Title: Improvements in or relating to chemical compounds of boric acid and tanning substances
IPC: C14C3/12
Filed: 1951-12-10
Abstract: Complex compounds are prepared by reacting a natural tannin and boric acid in an organic solvent.  Suitable solvents are methyl, ethyl, n- and isopropyl, butyl, amyl, allyl, and propargyl alcohols, formic, acetic, and propionic acids, esters of these alcohols and acids, acetaldehyde, acetone, methyl ethyl ketone, ethyl ether, and mixtures thereof.  A preferred solvent is a mixture of ethyl alcohol, acetic acid, ethyl acetate, and water in equilibrium proportions.  Reaction takes place at normal temperature or with warming, and the compounds formed may be separated by evaporating the organic solvent and recrystallization from ethyl acetate.  In examples boric acid is added to organic solvent extracts of oak bark and pomegranate tree bark.  The products may be used as tanning agents (see Group VIII) or as external remedies (see Group VI).ALSO:Solutions suitable for external treatment of the human or animal body affected by fungal or bacterial disease are prepared by reacting a natural tannin and boric acid in an organic solvent (see Group VIII).

Title: Improvements in or relating to web roll supporting mechanisms for printing and other machines
IPC: B65H16/08
Filed: 1929-09-24
Abstract: 336,758. Goss Printing Press Co., (Assignees of Crafts, C. S.). April 22, 1929, [Convention date]. Feeding and registering webs.-In a web-roll supporting mechanism for printing or other machines in which the roll is rotatably supported on a number of rollers, the rollers are adjustable axially for transverse register of the roll. Vertically movable members are provided to engage the ends of the axial orifice in the roll to keep the roll upon its support, and these members are mounted on pedestals relatively movable to accommodate rolls of different widths. The roll 25, Figs. 1 and 2, rests upon a pair of rollers 27, 28, preferably in the form of drums secured to hubs 32, Fig. 1, on stub shafts 33. These shafts 33 are mounted in roller bearings 29 carried by end frames 12, 13 slidable upon fixed bed-plates 10, 11 and adjustable thereon for transverse register of the roll by means of a rotatable spindle 70 threaded into the frame 12. Collars 36, 37 releasably secured to the rollers 27, 28, engage the sides of the roll and prevent lateral movement of the roll upon the rollers. The ends of the orifice in the roll are engaged by members 47 on spindles 48 rotatable in bushes 49 having a spherical portion 53 to permit universal movement in their bearings 52. The spindles 48 are axially movable in the bushes to engage and release the rolls but are normally held against such movement by collars 50 secured to the spindles by screws 51. The bearings 52 can slide laterally to an extent limited by the compression of springs 54, Fig. 2, mounted on pins secured to the bearings 52 and guided in the members 56 carrying the bearings. These springs resist any tendency of the roll to roll off the rollers 27, 28, and assist the return of the roll to normal position. The members 56 can slide freely vertically in pedestals 40, 41 mounted on rods 18, 19 secured to the frames 12, 13, and these pedestals can be spaced apart to accommodate rolls of dif. ferent widths and are secured in adjusted position by set screws 45. The tension of the unwinding web is controlled by a brake applied to one of the shafts 33 and comprising a brake drum 80 on the shaft engaged by brake shoe on a pair of levers 84 pivoted at their lower ends and connected at their upper ends by a pivoted link 90 carrying a spring, the tension of which may be adjusted by a hand-wheel nut 92. The rollers 27, 28 are connected together by gears 95, 96 and an intermediate gear 97 so that both rollers are equally retarded by the brake.

Abstract: 689,993. Rectifying. BRITISH THOMSONHOUSTON CO., Ltd., and LUDBROOK, L. C. Nov. 30, 1950, No. 29364/50. Class 38 (ii). In a supply circuit wherein a discharge device 10 serially connected with a load 16 across A.C. supply terminals 15 provides a control for the unidirectional current pulses in such load, the range of control of the device 10 is extended by an excitation circuit which renders the device conductive at a point nearer, than would otherwise be the case, the beginning and end of each positive half-cycle, e.g. when the anode 11 of the device is at a potential only a few volts above that of its cathode 12. This excitation circuit comprises the connection of a condenser 21 in series with a rectifier 19 between the anode 11 and cathode 12 of the device, the junction of these components 19, 21 being connected to the control electrode 13 of the device and the rectifier being so poled that the condenser is charged during each half-cycle when the anode is negative so as to provide a current pulse to initiate the discharge in the device when desired during the following half-cycles when the anode is positive. As shown, Fig. 1, applied to a pentode thyratron the condenser and rectifier are shunted across one limb 17 of a potentiometer 17, 18 shunting the device 10, and the discharge therein is initiated when desired by the reduction, such as by the superposition of a peaky waveform voltage, upon a bias potential applied to an auxiliary electrode 14. Applied to an ignitron, Fig. 2. the ignition instant is determined by a further discharge device 23 connected between the condenser 21 and the ignition electrode 13 of the ignition. A number of basic half-wave circuits shown may be embodied in known polyphase and bridge arrangements.

The Figure shows a power supply for a thermionic valve 3 which in the inoperative condition shown has a voltage dropping resistor 8 in series with the primary winding of the heater transformer 7 and resistor 5 in series with the A.C. supply to the rectifier 6 in the anode supply circuit. When the left hand button of switch 12 is depressed solenoid 4 operates and makes contact 1, the solenoid being held by the contact 14 after switch 12 is released. Switch 13 brings the valve into the operative condition when its left hand button is depressed by energizing solenoid 9, thus shorting out resistors 5 by contacts 2 and resistor 8 by contact 10. The solenoid is held operative by the circuit through contact 15 even when switch 13 is released. The circuit is returned to the inoperative condition with resistance in both heater and anode supplies by depressing the right hand button of switches 12 and 13.
