Two parts of castor oil may be added to decrease the stiffness and resiliency of the colloidal coating. The solution may be applied by spraying the solution through an atomizer using an excess of air. Parts only of the fabric or article may be treated by manipulating the atomizer or by interposing a stencil between the fabric and the spray. In the case of fabrics having long nap, the spray is directed on to the face of the fabric; in other cases, the spray is directed on to the rear face. A treating solution described in Specification 170,171 and containing cellulose acetate dissolved in acetone and having a clarifier of methyl alcohol and benzol, and a softener of salol and triphenyl phosphate may be employed.

Title: Improvements in cigarette-rod cutting devices
Inventor: BARDENHAGEN DIETRICH
IPC: A24C5/28
Filed: 1961-04-21
Abstract: 982,298. Cigarette-making machines. K. KÍRBER. April 21, 1961, No. 14504/61. Addition to 971,260. Heading A2C. In a cigarette rod cutting device of the kind described in the parent Specification the cutter shaft is adapted to be adjusted in pivotal manner in a plane parallel to the rod and inclined to the horizontal plane through the rod, and the oscillatory motion of the cutter about a radial axis directed towards the cutting edge is obtained by means of a cage member associated with an idler shaft which is pivotally adjustable consequentially upon pivotal adjustment of the cutter shaft, in a plane substantially parallel to the rod. As shown in Fig. 3 the cutter shaft 2 and the idler shaft 57 are connected obliquely by a Cardan joint, the position of the shaft 57 relatively to the shaft 2 regulating the oscillation of the cutting blade 34. A fork 54 (Fig. 8) is mounted at the end of the shaft 57. A pivot pin is mounted in the shaft 57 which is provided with an operating button 72 at one end and a pawl 82 at the other, the pivot pin being spring urged in the direction of the button 72. Operation of the button 72 causes the pawl 82 to rotate the shaft 87 which is geared to a worm 100 for advancing the blade 34 outwardly as it is worn. The shaft 87 is mounted in a tubular shaft 88 which extends through bores 93 in a cage 30 (Fig. 6). The ends 89 of the fork 54 are each provided with a bearing which supports pivot pins which extend into bores 55 of the cage 30. The shaft 88 is mounted in bearings 108, 109 of a cutter support 104. The shaft 2 engages a conical bore 111 in the support 104 and is rotatably supported in a gear-box 1 (Fig. 8). A drive shaft 113 drives the shaft 2 through the gearing in the box 1. A flange 114 is arranged on the gear box 1 inclined with respect to a horizontal plane. The flange 114 is provided with a graduation 115 for permitting adjustment of the box 1 and shaft 2 around the axis of the shaft 113 according to the desired length of cigarettes to be cut, which is dependent on the angular setting of the blade 34. Rotation of the flange 114 with respect to the housing is permitted by curved slots 116. During adjustment the clamping screws for the bearings 58 of the shaft 57 must be loosened. The bearing 58 is mounted on a block 117, the clamping face 118 of which lies in a plane substantially parallel to the cigarette rod and approximately in the same plane as the face 119 of the flange 114. Slots 120 in the block 117 permit the necessary adjustment.

Title: Improvements in and relating to volt ampere meters
IPC: G01R11/64
Filed: 1942-10-20
Abstract: 560,246. Volt-ampere meters. BRITISH THOMSON-HOUSTON CO., Ltd., (General Electric Co.). Oct. 20, 1942, No. 14705. [Class 37] A volt-ampere meter comprises a differential measuring instrument having a pair of energising circuits and responsive to the difference of the currents therein, means for energising the circuits in parallel by currents, the total of which is proportional to one of the quantities, and a regulator responsive to the other quantity for varying the relative flow of currents in the parallel energising circuits such that the response is proportional to the volt-amperes. In the instrument shown in Fig. 1 a power line 10 feeds the primary of a current transformer 11, the secondary of which energises reverse torque bimetal elements 13, 15 in parallel. A conducting shaft 12 is fastened to the inner ends of the spirals 13, 15 and also to the inner end of a central spiral 14 which is not of bimetal and serves as a common connection from the transformer secondary through the shaft 12 to the inner ends of the bimetal spirals 13, 15. The outer end of the spiral 14 is adjustable for adjusting the zero setting of the meter. The outer end of the spiral 13 is connected directly to the other terminal of the transformer secondary, while the outer end of the spiral 15 is connected to the same point through a resistance 20. This is of material such as iron, nickel, or tungsten wire having a positive temperature coefficient, and is enclosed in an evacuated or gas-filled tube 23 together with a heater resistance 24 which is connected across the secondary of a potential transformer 25. The movement of the shaft 12 caused by the differential torque of the spirals 13, 15 is conveyed through multiplying gearing 26 to a shaft 12a carrying a pointer 27, which may move a friction pointer 29 to indicate the maximum demand. The tube 23 may also contain a resistance of negative temperature coefficient which is connected in series with the spiral 13. In another arrangement, Fig. 3, a moving-iron instrument has two coils 31, 32 which are arranged in opposition and connected in parallel, through resistances 40, 41 to the secondary of the current transformer 11. These are situated in the two legs of a U -tube 36 containing mercury 37 and provided with expansion chambers 34, 35, the chamber 34 containing a resistance 38 which is heated in response to the voltage of the line 10.

Abstract: 1283030 Substation circuits; automatic volume control SIEMENS AG 26 March 1970 [28 March 1969] 14710/70 Headings H4K and H4R A substation circuit includes a two stage transistor amplifier with a non-linear resistance element connected in parallel with a load resistance of the first stage and with the input of the second stage, and arranged to vary the output power in accordance with the current supplied over the exchange lines. As shown, transistors T1 and T2 form the respective stages of the amplifier which connects the substation microphone M to the telephone line + A, - A. A Zener diode D1 forms the non-linear resistance. Short telephone lines give rise to higher power supply currents which cause the Zener diode to adopt a low resistance which shunts resistor R1 upsetting the match between transistor T1 and the microphone. The resultant reduced output of this transistor is further attenuated by the increased shunting effect of the Zener diode. Thus for short lines the output applied to the output stage T2 is reduced to compensate for line length.
