Title: Apparatus for uniform web feed
IPC: A24C5/20
Filed: 1966-07-19
Abstract: 1,104,389. Automatic tension control. CONSOLIDATED CIGAR CORPORATION. July 19, 1966 [April 12, 1966], No.32425/66. Heading G3R. Uniform tension is maintained in a web by a tension detector engaging and disengaging a clutch coupling a high speed drive to the web so as to over-ride a low speed drive which is coupled through an over-running clutch. In Fig. 1, overlapping and laterally offset cigar binder and wrapper bands B of reconstituted tobacco are drawn from reels 17 and 18 and helically wound on a tobacco rod in a cigar making machine 11. The tension in each band is automatically controlled in a similar manner and, considering one band, reel 17 is braked by a roller 32 incorporating an adjustable frictional device resisting rotation. The band is withdrawn from reel 17 by a driven feedroller 49 geared to a pressure roller 57 which is eccentrically mounted and spring- loaded towards roller 49. Roller 49 is normally driven at a low speed from a shaft 82 through a first chain 78a and an over-running clutch, but, as machine 11 consumes the band, a lever 97, resting in a loop of the band, is raised until a switch S 2  is cam-operated to energize, through a relay system, an electromagnetic clutch incorporated in the drive to roller 49 so that the latter is driven faster through a second chain 79a. When lever 97 falls sufficiently, a second switch S 1  is cam-operated to restore the low speed drive. Thereafter the speed of roller 49 alternates between the two values to maintain loop length, and hence tension, between limits. Weighting of lever 97 and the position of the switch cams are adjustable to facilitate setting the tension limits.

Title: Manufacture of new azapentylene diammonium compounds
Filed: 1952-12-22
Abstract: The invention comprises new secondary 3-azapentylene - (1,5) - di - trialkyl ammonium compounds of formula:  <FORM:0719610/IV (b)/1> in which R1-R6 represent alkyl residues with 1-3 carbon atoms and A- stands for an anion, and secondary amine salts thereof.  A- may be a halogen ion, an ion of a therapeutically applicable acid, for example methyl sulphuric acid, or of an alkyl or aryl sulphonic acid or of an organic carboxylic acid, for example acetic acid, propionic acid, succinic acid, tartaric acid, citric acid or benzoic acid, or the hydroxyl ion.  Particularly valuable compounds of the above formula in which R1 to R4 are methyl residues are N,N,N1,N1 - tetramethyl - N,N1 - diethyl-3 - azapentylene - (1,5) - diammonium compounds, e.g. the dibromide, and the N,N,N, N1,N1,N1 - hexamethyl - 3 - azapentylene-(1,5) - diammonium compounds, e.g. the diiodide.  The new compounds are obtained when an azalkane diamine of formula <FORM:0719610/IV (b)/2> is treated with quaternating agents which are capable of introducing an alkyl residue with 1-3 carbon atoms. Suitable quaternating agents are alkyl halides, such as methyl or ethyl chloride, bromide or iodide; dialkyl sulphates such as dimethyl or diethyl sulphate; or alkyl or aryl sulphonic acid esters such as p-toluene sulphonic acid methyl ester.  The reaction may be carried out in the presence of solvents such as alcohol or acetone.  The quaternary ammonium salts may be converted into their quaternary ammonium hydroxides, for example by reaction of the halides with silver oxide or of the sulphates with barium hydroxide or by treatment of the quaternary salts with anion exchangers.  From the bases thus obtained the quaternary salts of such acids as acetic, propionic, succinic, tartanic, citric and benzoic acids may be obtained by reaction with the acids. Secondary amine salts may be obtained by reacting these salts with acids such as hydrohalic acids. In the examples: (a) o ,o 1-tetramethyl diethylene triamine (obtained by hydrogenation of dimethyl-amino-acetonitrile) is dissolved in alcohol and reacted with methyl iodide to give N,N,N, N1,N1,N1 - hexamethyl - 3 - azapentylene - (1,5) diammonium diiodide of formula: <FORM:0719610/IV (b)/3> by treating with hydrogen iodide the hydriodide of formula:  <FORM:0719610/IV (b)/4> is obtained; (b) o ,o 1-tetramethyl-dimethylene triamine is reacted with ethyl iodide to give <FORM:0719610/IV (b)/5> and (c) o ,o 1-tetramethyl diethylene triamine is reacted with ethyl bromide to give <FORM:0719610/IV (b)/6> which is reacted with silver oxide to give the dihydroxide; the dihydroxide is reacted with hydrochloric acid to give N,N,N1,N1-tetramethyl - N,N1 - diethyl - 3 - azapentylene-(1,5)-diammonium dichloride.

Title: Improvements relating to transmission gear
IPC: B62M1/00
Filed: 1925-12-30
Abstract: 265,747. Siggam, J. Dec. 30, 1925. Pedals.-A crank driving-device, applicable to cycle driving mechanism, agricultural implements, &c. embodies a connection between a crank and a co-axial driven member which, when the driving pressure is relaxed as when passing through dead centre positions, allows the crank to advance independently through a predetermined angle and to take up the drive again when occupying a more effectve position. A pivoted dog or pawl 3 on a driving plate 1 secured to the crank 2<1> is formed with laterally extending lugs 8, 9 adapted to effect driving engagement with teeth 5 projecting from the face of a co-axial sprocket wheel 6. The dog when freed is tilted by a spring 11, a shoulder 13 thereon abutting against the periphery of the driving plate 1. When the lug 8 encounters an inclined tooth 5 it rides up the face thereof so that the tooth engages the recessed face 10 of the inner lug 9 and rotation is transmitted until the driving pressure is relaxed, whereon the spring 11 causes disengagement. The action of the spring may be regulated by an adjustable mounting 22. A stop 14 may be brought into the path of the lug 8 to render the driving connection permanent. When the load is light the lug 8 may not ride completely up a tooth, a continuous drive thus being transmitted until a certain load is reached. This is referred to as an automatic two speed gear. In the form shown in Fig. 12, the dog 3 is directly pivoted on the crank, being drawn against a stop 13<1> thereon by a spring 11. The teeth may, as shown in Fig. 7, be secured to the sprocket plate 6 by screwed stems 23 and nuts 24, the edges of the teeth being slightly inclined to retain the dog or dogs in engagement. Several dogs may be used in conjunction with a single tooth or vice versa.
