IPC: D01H1/02
Filed: 1921-10-03
Abstract: 195,658. Potter, J. C. Oct. 3, 1921. Ring and traveller frames; driving-arrangements; building-motions; spindle rails; spindle apparatus; anti-ballooning arrangements.-In cotton ring-spinning and twisting frames non- rotating rings, with travellers which derive their motion only from the pull of the threads, are mounted in stationary supports and high speed spindles are mounted in a reciprocating carriage. The ring rails are secured by flanges 16 to an angle-bar 13; and the spindle rails on each side of the frame are connected by cross-bars 23 upon which the tin rollers are mounted, so as to form a removal unit which is supported on slides 28 by means of screws 26. The building-motion and the tin roller driving-gear are arranged between heads 11, Fig. 1, at the middle of the frame, and the slides 28 on each side thereof are reciprocated by a lever 38 so that one is falling when the other is rising. The lever 38 is oscillated by a cam 45, and is connected by sprocket chains 41, Fig. 9, with geared shafts 31 carrying wheels 30 geared with the slides. The building-motion lever is provided with ratchet-gearing 48 of usual construction. The tin-rollers are driven from a countershaft pulley 36 by a belt 33 which is tensioned by a pulley 34. The drawing-rollers are driven from the tin roller of each unit by a pinion 56, which meshes with a gear 57 on a shaft connected by sprocket-gearing 59 with a shaft geared with the front-roller shafts. The building-motion cam is driven from an intermediate wheel 65 of the roller gearing by a sprocket chain 67 and bevel and worm gearing. Tubular antiballooning devices 50, provided with inclined or overlapping threading slits, are pivoted on brackets 53 on the flange 16 of the ring-rail. A tube 74, Fig. 10, provided with an oil-cup at one end, is clamped to the bolster cases by a block 77 and serves, by means of outlets 80, to lubricate all the spindles. Holes 81, which serve for punching the outlets, also serve for hand-oiling, and are normally covered by a plate 83 provided with a tail 85 to retain the spindle during doffing. Reference has been directed by the Comptroller to Specifications 3854/74, 6155/00, 25986/01, and 2499/04.

Patent GB-1362888-A (GB)
Title: Motor-driven time switch
IPC: H01H43/10
Filed: 1972-06-08
Abstract: 1362888 Time switches DIEHL 8 June 1972 [18 June 1971] 26705/72 Heading H1N A motor driven time switch having a manually operable member for setting a time interval is provided with means operable to prevent such manual adjustment during a timing operation. As shown, rotation of knob 4, and hence shaft 3, clockwise causes arm 10 to entrain disc 9 (by means of its interior "dog" 25) and rotate it until cam lobe 26 abuts a stop 24 whereat contacts 27 are closed and synchronous motor 13 is energized. This drives gear 7 via reduction gearing 12 and, through friction clutch 8, returns shaft 3 until arm 10 engages the other side of "dog" 25 and entrains disc 9 to open contacts 27. A rotary coupling member 20 continuously engaged with a gear 6 on shaft 3 is axially movable by a device 23 to engage the gear 7, thus providing a rigid coupling from motor 13 to shaft 3 whereby manual rotation of knob 4 is prevented. The device 23 may be operated, for example, by changes in voltage, air pressure or moisture content. In another embodiment (Fig. 2, not shown) the friction clutch 8 is omitted so that the shaft 3 and knob 4 do not commence the return to the start position until device 23 couples gears 6 and 7. In each embodiment, after full clockwise movement to energize motor 13, the knob 4 can be adjusted to set a desired time interval prior to the coupling by device 23, but not thereafter.

Title: N-alkyl-piperidyl-methylphenothiazines
IPC: C07D279/18
Filed: 1955-09-19
Abstract: The invention comprises compounds of the formula <FORM:0773037/IV(b)/1> and their salts, in which R1 is a halogen atom, a C1 to C4 alkoxy group or a C1 to C4 alky group and R2 is an alkyl group.  Such compounds can be obtained by reacting the appropriately substituted phenthiazine with an N-alkyl-piperidyl-4-methyl chloride at elevated temperatures, e.g. 150-200 DEG  C., and, if desired, under elevated pressure without an additional acid-binding agent.  Alternatively, the substituted phenthiazine is first converted into its sodium, potassium, lithium or magnesium compound or at least two equivalents of metal donor are added before the reaction with the N-alkyl-piperidyl-4-methyl chloride.  In Examples (1) and (3) 3-chlorophenthiazine is boiled with sodium amide and then reacted with N - methylpiperidyl - 4 - methyl chloride to give, after removal of an isomer, 3-chloro-10-(N - methyl - piperidyl - 41) - methyl - phenthiazine which is converted into its tartrate and naphthalene-1,5-disulphonate.  In a generally similar manner are prepared (2) and (4) 3-methyl-10 - (N - methyl - piperidyl - 41) - methylphen - thiazine, and its naphthalene-1,5-disulphonate; (5) 3 - methoxy - 10 - (N - methylpiperidyl - 41) - methylphenthiazine and its tartrate.
