Abstract: 1311973 Sewing machine HUSQVARNA VAPENFABRIKS AB 13 July 1970 [14 July 1969 (2)] 33813/70 Heading D1G A sewing machine has a presser foot (on a bar 37) and a work feeding foot (on a bar 9), driven by lift mechanism 5, 6, 7 to exert pressure alternately on work to be sewn, a four motion lower feed dog (12, Fig. 7, not shown), the work feeding foot being reciprocated in a feeding direction by mechanism 30, 31, 33 adapted to be connected to the feed dog driving mechanism 16. The arrangement is such that when the presser foot is manually raised and swung to one side the lift and feeding mechanisms of the feeding foot are disconnected. The lift movement is derived from a cam 5 journalled on the drive shaft 15 and normally dogged to the latter by mechanism 42, 43 to rotate with the shaft. Link 6 engages the cam and has one end pivoted to one arm of the bell crank lever 7 pivoted to the feeding foot bar 9, the other arm carrying a hook 10 engaging the presser bar 37. Feed advance is provided by a link 33 having at one end a peg 56 normally engaging the usual feed motion fork 16 embracing an eccentric 14 on the drive shaft and connected to the feed dog mechanism. The derived motion of link 33 is transmitted by bell crank lever 31 and link 30 to a lever 29 (Fig. 10) which co-operates with a rack 27 and a toothed sector 26 guided in a slide in the machine head. The feeding foot bar 9 is slidably guided at its upper end 24 and is slidably journalled in a spherical bearing 25 received in the sector 26. Action (Fig. 16). When the presser bar 37 is raised a peg 38 thereon engages pivoted member 39 to swing it to a position where it is retained, with the presser bar, by a spring device 49, 50, a rod 41 moving rightwards to disengage the mechanism 42, 43 connecting cam 5 to the drive shaft, and swinging link 33 clockwise to disengage its lower end from the feed fork 16 and engage a notch 57 on link 33 with a stationary peg 56. A detent (54, Fig. 18, not shown) is provided to engage a notch in the released cam 5 to prevent its rotation. In modifications, not shown, the engagement and disengagement of members 33 and 16 is carried out magnetically by a solenoid; the cam 5 can be attached to the shaft 5 by a magnetic coupling; and a thrust rod may be provided to engage either or both feet, the rod being connected with a lever to actuate rod 41, the latter being disengaged when a normal presser foot replaces the former feet.

Abstract: 512,657. Drying gases; revivifying desiccants. LITTLE, Inc., A. D. Dec. 8, 1937, No. 34025. Convention date, Dec. 9, 1936. [Class 34 (i)] [Also in Group III] In processes for evaporating solutions, e.g., brine, calcium chloride solutions used for dehumidifying gases, solvent solutions used for extracting fats &c of the kind in which the vapour evolved from the solution is compressed and used as heating agent for preheating and evaporating the solution by passing the vapor and condensate produced therefrom in indirect heat exchange with the solution the condensate is passed through heat-exchange conduits of smaller cross section than those used to carry the vapour. In distilling brine to obtain pure water the heat exchange vessel comprises an insulated column 68 to the bottom of which the brine is fed from a tank 10 and pipe 9, the brine rising upwardly and overflowing through a centrally disposed pipe 12. Vapours evolved are drawn off through baffles 17 and a pipe 2 having a one way valve. 61 by a reciprocating pump 60 which compresses the vapours and feeds them through a pipe 3 having a valve 62. The hot vapours then flow through a heat exchanger coil 5, in which they give up heat to the solution and thus evaporate it while being themselves condensed, the condensate then flowing through a coil 6 of smaller cross-sectional area in which the solution is preheated by the hot condensate which is finally removed through line 8. A modification is described in which the distillation chamber and heat exchanger coils are arranged horizontally. As applied, Fig. 7, to the' dehumidification of air, fed by a fan 28 through a chamber 25, where it is dehydrated by calcium or lithium choride solution sprayed through a sprayer 27, the moisture absorbed by the solution is removed by passing the solution through pipe 109 into an evaporator 163 of the type described from which the moisture is removed as vapour by the pump 60 and fed through the heat exchanger coils 5, 6 the dehydrated solution being recirculated through a pipe 112 provided with a core 113, Fig. 8, to obtain maximum heat-exchange with the inflowing solution.

Title: Preparation of organic dicarbamates
Inventor: BEINFEST SIDNEY
IPC: C07C271/06
Filed: 1957-11-01
Abstract: Organic diol dicarbamates are prepared by reacting urea with an organic diol in a reaction zone in the presence of an alkanol or alkoxyalkanol solvent having a boiling point in the range 64 DEG  to 150 DEG  C. and an aluminium alkoxide derived from an alkanol having a boiling point in the range 64 DEG  to 150 DEG  C.  The reaction is advantageously effected at a temperature in the range 100 DEG  to 180 DEG  C., and it is convenient to separate the alkanol from the reaction product, e.g. by distillation, and recycle it to the reaction zone.  The process may particularly be applied to alkane diols such as butane-1 : 3-diol, 2-methyl - 2 - n - propyl - propane - 1 : 3 - diol and pentane-1 : 5-diol, when advantageously 0.8 to 1.5 moles of urea are reacted with about 0.5 mols. of the alkanediol in the presence of 1 to 1.5 mols. of the alkanol solvent and 0.005 to 0.25 mols. of the aluminium alkoxide per mol. of diol. Examples of the preparation of the dicarbamates of these diols and of 2-butene-1 : 4-diol are given, the solvents used being n-butanol and n-propanol and the catalysts aluminium isopropoxide and aluminium n-butoxide. Other diol starting materials and other solvents are also referred to.

[Class 40 (iv).] Relates to an electrostatic telephone transmitter of the type comprising an electrode mounted in a member having a facing the plane of which is parallel to the face of the electrode and a diaphragm which co-operates with the electrode and is clamped under tension around its periphery and positioned on the facing and consists in the arrangement of a tension ring behind the diaphragm, the cap ring of the transmitter being independent of the means for tensioning the diaphragm. As shown, the transmitter comprises an axially bored steel body member 1 provided with a coaxial circular recess 2. Inside the bore of the member 1 slides a sleeve 3 having a flange 4 at one end resting against a rubber ring 8 in the recess 2, the other end of the sleeve 3 being provided with a fine screw thread 5 with which engages a collar 6 having a part 7 which fits over the member 1, the arrangement providing for a micrometric adjustment of the sleeve 3. A spindle 10, carrying at its forward end the fixed electrode 11, is arranged within the sleeve 3 and insulated therefrom by ebonite rings 9, the spindle and sleeve being locked together by a nut 13 and insulated by mica washers 14. In order to equalize the static pressure on either side of the diaphragm 12, the electrode 11 is formed with a duct 15 leading from the edge thereof and extending axially through the spindle 10 on the outer end of which is mounted a bell 16 across which is stretched a rubber diaphragm 17. The diaphragm 12 is clamped between rings 20, 21, a thin brass or phosphor-bronze ring being interposed to prevent crumpling and abrasion of the diaphragm during screwing-up, and the diaphragm is tensioned by a ring 22 sliding in ring 20 and pressed against the diaphragm by an adjusting ring 23. A flanged cap ring 24 is screwed on to the ring 20, which is secured by screws 19 to a flange 18 on the member 1, and the diaphragm is clamped between the tensioning ring 22 and the flange 25 of the cap 24. This flange is made as thin as possible so as to make the air cavity 25a in front of the diaphragm as shallow as possible. The width of the flange 25 is made such that when the diaphragm and complete frame member 20 .. 24 are mounted on the member 1, the diaphragm is held between this flange and the face 26 of the member 1. During manufacture, the electrode 11 is screwed forward until its face is substantially coplanar with the face 26 and the two are then ground accurately coplanar and lapped together on a surface plate thus ensuring accurate parallelism between the diaphragm and its electrode.
