Title: A process of treating regenerated cellulosic articles to prevent discolouration
IPC: D06P3/10
Filed: 1956-03-01
Abstract: Regenerated cellulose fibres, filaments or pellicles are washed free of soluble impurities and are treated with a solution at a pH of 3 to 6 containing HSO3 ions and dried in the presence of the HSO3 ions. The source of the HSO3 ions may be sodium, potassium or lithium bisulphite, sulphurous acid, sulphites or anhydrous metabisulphites (e.g. Na2S2O5).  The treating solution may be obtained by bubbling SO2 gas into a solution of an alkali metal hydroxide.  The pH of the treating solution may be adjusted with sodium hydroxide or hydrochloric acid and the solution may contain a textile auxiliary such as a polyoxyethylene glycol monoether of sorbitanmonolaurate or sorbitan-tristearate, sorbitan monopalmitate, lauryl sulphate, white mineral oil in the presence of sulphated butyl oleate or cetyl-ethylmorpholinium ethosulphate.  The solution may be applied to yarn directly from the spinning operation after the immediate after-treatments, to a tow of staple fibre after desulphurizing and bleaching or to cakes of continuous filaments.  The treated material may be oven-dried at temperatures up to 200 DEG  F.

Title: Drive for a time clock
IPC: G04C15/00
Filed: 1974-02-13
Abstract: 1447906 Electronic timepieces ZENTRA ALBERT BURKLE KG 13 Feb 1974 [26 Feb 1973]  6529/74 Heading G3T [Also in Division H2] A drive for a time clock comprises a standby supply circuit and a synchronous motor 1, the circuit including an accumulator 9, an oscillator 11 and a switching circuit 18 for supplying power to the motor in the event of failure of a mains supply connected between terminals R, Mp. When the mains supply is present it drives the synchronous motor 1 which, via a gear train 2, operates contacts at a pre-set time. The oscillator 11 may be a crystal oscillator or a 50 Hz multivibrator, a frequency divider 12 being provided if a crystal oscillator is used. The accumulator is charged via a diode 8 whilst a diode 7 and a capacitor 10 maintain transistors 13, 14 conductive to prevent the anti-phase outputs Al, A2 of the oscillator 11 from operating the circuit 18. On failure of the mains supply, the transistors 13, 14 are switched off so that when the output A2 is positive, transistors 15, 17 are switched on to supply a current Ic 1  to a capacitor 19 and the synchronous motor 1. When the output A1 is positive, a transistor 16 is switched on so that a discharge current Ic 2  flows through the motor. The motor is therefore supplied with an alternating current at a frequency of 50 Hz. In a modification the circuit 18 comprises a bridge network of four transistors and in a further modification suitable for higher voltage motors a voltage multiplier including a blocking oscillator supplies the circuits 11, 12, 18.

Trueing and balancing rotating tools; gauges. -In controlling the operation of grinding or abrading machines, a member secured to the trimming tool adjusts at each traverse the surface of an abutment which actuates an indicating or controlling device for the cross feed of the machine. In one form, Fig. 1, a separate disc h on the spindle of the grinding wheel c coacts with the controlling abutment d, this disc being reduced at each traverse by a suitable tool, not shown, to the same extent as the grinding-wheel is reduced by the trimming tool. In a modification, Fig. 2, an abutment a frictionally mounted in the tool slide may coact with an indicator b. In order to compensate automatically for wear of the wheel, when the wheel is moved past a trimming tool f the abutment moves past a projection k which resets the abutment a in its previous position relative to the wheel surface. The Specification as open to inspection under Sect. 91 (3) (a) describes also a modification in which the surface of the grinding wheel c, Fig. 1 (Cancelled), makes frcitional contact with an abutment d to close electrical contacts a, b controlling the cross feed of the wheel.

Abstract: 1386031 Brake pedal linkages; linkwork H O SCHROTER 12 Feb 1973 [12 Feb 1972] 6825/73 Headings F2E and F2K A brake pedal 6 pivotally mounted on a pin 1 carries an axle pin 2 for a roller 11 which cooperates with a cam lever 7 to which is pivotally attached at a pin 4 the piston-rod 10 of a master cylinder; the cam profile of cam lever is of substantially hyperbolic convex form and during operation of pedal 6 the roller 11 first rides up arm 13 towards vertex 12 of the hyperbola into closer proximity with the fulcrum 3 of the cam lever 7 and thereafter rides up arm 14 which extends directly towards fulcrum 3. The transmission ratio increases as roller 11 rides up arm 13 but as it rides beyond vertex 12 the transmission ratio remains substantially constant. In the brake released condition the axis of the piston-rod 10 makes an acute angle of between 50 and 60 degrees with the line joining pin 4 and fulcrum 3 and this angle increases as the cam lever 7 is pivoted during braking. The x-axis of the hyperbola passes through pin 4, and the distance between vertex 12 and fulcrum 3 is 1À4 times greater than the distance between the pin 4 and fulcrum 3. As shown, a pretensioned spring 9 connects pin 2 and pin 4 which spring 9 provides a restoring force during travel of roller up arm 13 but thereafter assists deflection of the pedal 6. In the released position the cam lever 7 bears against a stop 8 attached to a base-plate 5 which is bolted to a bearing bracket containing the pivot pin 1.
