Title: Improvements in or relating to programming devices for water softening plants
Inventor: HEYL HANS-JURGEN
IPC: B01J49/85
Filed: 1968-02-08
Abstract: 1,208,152. Fluid actuation of switches. H.-J. HEYL, and E. HEYL, [trading as HEYL K.G. GES FUR ANALYSEN-TECHNIK GEB]. 8 Feb., 1968 [9 Feb., 1967], No. 6341/68. Heading H1N. A switch is closed after a predetermined quantity of water has flowed through a water softener to initiate a regeneration programme and the actuating mechanism is automatically reset to commence a subsequent metering cycle. A commercial metering device 16 is driven by a known flow meter 2 (Fig. 1) and by suitable reduction gearing drives a disc 36 (Fig. 1) below, and coaxial with, a switching disc 44. A friction roller 80 is urged by spring 96 against the peripheries of both discs to couple the drive to the disc 44 which thus rotates until an adjustable preset arm 48 thereon engages arm 56 to actuate switch 54. Switch 54 energizes a motor 58 (Fig. 1) which drives a programming disc 66 carrying adjustable pins 70 in a ring of threaded holes 68 to act on a star wheel 72 and actuate a switch 64. The initial movement of disc 66 lifts a follower out of a recess 74 to close a switch 62 in a holding circuit for motor 58, and allows a follower 90 to drop into the recess 74. Arm 92, rigid with arm 88 carrying the follower 90, abuts an arm pivoted at 84 to lift roller 80 out of engagement with discs 44 and 36 whereupon a spring 46 returns disc 44 to its starting position wherein a pin 50 abuts a stop 52. Further slight rotation of disc 66 then cams follower 90 out of recess 74 to bring roller 80 once again into engagement with discs 36 and 44 to commence a further metering cycle. The edges of discs 36 and 44 may be smooth or serrated, but in a modification (Fig. 3, riot shown) they are chamfered to form a Vee-groove in which a peripheral 0-ring on roller 80 engages and the slight tilt thereby produced on disc 44 causes additional frictional drive from an axial bush of disc 36 (on which disc 44 is otherwise loosely mounted) and enables the pressure on roller 80 to be reduced and hence reduces the load on programming disc 66. Instead of a peripheral recess 74 the disc 66 may be provided with an internal cam track. In another modification (Fig. 4, not shown) the disc 36 and roller 80 are replaced by an eccentric and pawl which drives disc 44 by means of ratchet teeth on its periphery, and release of the drive (for spring-return of disc 44) is by lifting the pawl (instead of roller 80). In further modifications (not illustrated) the metering device is constituted by a gear of the reduction gearing, instead of disc 36, and this is mounted on a rocker arm with either a friction wheel drive to the switching disc 44, or a direct toothed connection therewith; an axial clutch coupling may be actuated by the arm 88, and the latter may co-operate with a face cam of programming disc 66.

Filed: 1928-02-29
Abstract: 313,021. Illingworth, S. R., and Illing- worth Carbonization Co., Ltd. Feb. 29, 1928. Retort and like doors.-A door F for a vertical retort B is mounted on a shaft 9 having keyed to it a counterweight lever 11 connected by a link 12 with a lever 13 on a second shaft carrying an operating-handle 15, the pivotal points of the link being arranged to lie in dead-centre positions when the door is fully opened and closed. The door is detachably secured to bolts' 4 by plates 5 engaging grooves 6 in the bolts, and the bolts are loosely mounted in arms 8 keyed to the shaft 9. The lever arm 11 carries a counterweight 10 and the lever 13 is mounted on a sleeve 14 carrying the operating handle 15 and rotatable on a shaft 22 carried by a bracket 16 on the supporting post E. To close the door the handle 15 is moved in the direction of the arrow 20, the parts moving from the dotted to the full-line position. In the closed position the link 12 and lever 13 are at dead centre, the pivotal points being in a vertical line above the shaft 22, while in the open position the pivotal points lie vertically above the shafts 9, 22. Slotted catch members 17 mounted on a shaft 18 are operated by a hand lever 19 when the door is closed to engage with the ends of the arms 8, and the door is finally tightened against its seating 2 by screwing the bolts 4 through collars 7 bearing against the arms 8. A stop 21 limits the movement of the handle 15, and the shaft 22 projects beyond the sleeve 14 to limit the movement of the link 12.

Title: Coupling fitted with synchronizing gear, especially for the change-speed gears of motor vehicles
IPC: F16D23/04
Filed: 1940-04-09
Abstract: 538,216. Friction and claw clutches. GANZ & CO., Ltd. April 9, 1940, No. 6404. Convention date, April 14, 1939. [Class 80 (ii)] Relates to positive clutches the members of which are synchronized by a coil friction clutch brought into action by a second friction clutch, which is of conical form. The positive clutch comprises teeth 15 on a gear-wheel 9, which can be engaged by teeth 16 on a sliding coupling- member 2 splined on a shaft 1. Rods 4, slidably mounted on the shaft are detachably connected by spring-pressed balls 6 to the coupling-member, so as to move therewith. Movement of the coupling-member by a fork 3 in a direction to engage the clutch causes the rods 4 to displace a conical spring-pressed clutch-member 7, which is splined on the shaft, into engagement with a conical surface on a sleeve 10, which is rotatably mounted within the gear-wheel. Inside the sleeve is mounted a coil spring 11 having at its ends upturned portions 12, which project through an aperture in the sleeve and into a recess 13 in the gear-wheel. The rotation imparted to the sleeve by the conical member 7 forces the upturned ends of the spring 11 towards each other, so that the spring grips the shaft and frictionally connects it to the gear-wheel. Further movement of the coupling-member causes engagement of the clutch teeth 15, 16. The resistance offered by the member 7 to the rods 4 forces the balls 6 from their seats in the rods, so that the coneclutch is disengaged by its spring. The coil spring 11 may be arranged to act by expansion instead of contraction, so that it grips the inside of the hub of the gear-wheel.

Title: Quaternary ammonium salts of tri-(aminoalkoxy) benzenes
IPC: H01J17/04
Filed: 1952-03-13
Abstract: Quaternary ammonium salts of the general formula <FORM:0703893/IV(b)/1> where R1 R2 are the same or different lower alkyl radicals of 1-4 carbon atoms or together with the nitrogen atom form a piperidine ring, R3 is a lower alkyl radical of 1-4 carbon atoms, X is a halogen atom and n is an integer greater than 1, are prepared by reacting the corresponding tri-(omega-dialkylaminoalkoxy) benzene with a lower alkyl halide R3X in the presence of a solvent medium in which both reactants are soluble, suitably by heating the reactants in benzene, toluene, ethyl acetate acetone, methyl ethyl ketone, or methyl, ethyl or isopropyl alcohol, at the boiling point of the solvent.  The preferred product, the tri-ethiodide of tri-1:2:3-(b -diethylaminoethoxy) benzene is obtained in one of two forms melting at 250-255 DEG C. and 152-153 DEG C. respectively, according to whether the reaction is conducted in a substantially anhydrous solvent or in a solvent medium containing a small proportion of water.  The low melting form may be converted to the higher melting form by heating.  Examples describe the preparation of tri-1:2:3-(b -diethylaminoethoxy) benzene tri-ethiodide in both forms by reacting tri-1:2:3-(b -diethylaminoethoxy) benzene with ethyl iodide in ethyl acetate, methyl ethyl ketone and acetone.  By similar methods the corresponding trimethiodide and tri-propyliodide are obtained and also the tri-methiodide and tri-ethiodide of tri-1:2:3-(b -dimethylaminoethoxy) benzene and tri-1:2:3-(b -piperidinoethoxy) benzene.

Title: Improvements in machines for making wired box parts
IPC: B27M3/36
Filed: 1938-03-03
Abstract: 496,624. Making wired box blanks and box parts. STAPLING MACHINES CO. March 3, 1938, No. 6698. Convention date, April 3, 1937. [Class 18] In a machine for making wired box blanks and box parts, e.g. of the kinds shown in Figs. 1, 2, and 3 and for making and consolidating a loop in the end of the wire, the box parts E, Fig. 5, are placed on conveyers 3, and fed through a machine 1 which secures the wires on the box parts, e.g. as described in Specification 248,735, [Class 18], in which the conveyers move continuously, after which the blanks pass beneath a clutch control arm 6, and are engaged by belts 5, Fig. 7, which move quicker than conveyer 3 to permit formation of the loop and stapling thereof in a machine 2, which may be as described in Specification 409,995, while the blanks are stationary. Belts 5 are actuated through gears 60, 61, from a pulley 39, clutched to shaft 40 by a clutch 18, which is actuated by movement of control arm 6 through the sequence 19, 20, 21, 22, and a collar 24 which engages and disengages clutch 18. The clutch 18 is also controlled to stop belts 5 while the loop-forming mechanism is being actuated by utilizing a top link 32 pivoted on a member 34 on a shaft 35 the rocking of which operates clutch collar 24 through a sequence 38, 31, 22. The rocking of shaft 35 also throws into action the loopforming mechanism, shaft 35 acting through a sequence 44, 45, 46, 47 to permit a loaded spring 48 to rock a shaft 49 which, through a sequence 50a, 50b, 50c, 50d moves the yoke of a clutch collar 56 on a shaft 58 to partially engage a clutch 53 to connect shaft 79 to motor shaft 83, shaft 79 actuating the main shaft 54 of the loop-forming mechanism through the sequence 78, Fig. 8, and 80, 81. The same rotation of shaft 49, through the sequence 50a, 50b, 50c. 50e. 50f, 50g, throws a buffer arm 51 from the position shown in Fig. 8 to that shown in Fig. 9, to permit a cam 52 to be released and allow shaft 54 to be rotated by chain 80. While shaft 54 turns, cam 52 contacts a lobe 55 on buffer arm 51 and moves the latter thus moving clutch collar 56 through the sequence 50g, 50f, 50e, 50d so that the collar 56 completely engages clutch 53. As table T is lowered during the loop forming, a cam 63 thereon contacts member 22 and so keeps clutch 18 disengaged. The loop-forming and fastening mechanism is stopped when the loop-forming is completed by disengaging clutch 53 by a sequence 56, 68, 67, 65, and a frame 64 and piston 75 which are mounted on table T and rise and fall with it. Compression spring 48 is reloaded by shaft 68 through shaft 49, this re-engaging catch 47, the release for which having been returned to initial position by the disengagement of blank E from stock stop 32 thus permitting rotation of shaft under the influence of spring 69, crank 44, fork 45 and shaft 46 being thereby returned to initial position, thus returning the release for catch 47 into engaging position.
