Title: New quinuclidines and process for their manufacture
Filed: 1955-10-06
Abstract: The invention comprises quinuclidines unsubstituted in positions 2, 4, 5, 6, 7 and 8 and substituted in the 3-position by a free or functionally converted carboxyl group, and also containing either a hydrogen atom in the 3-position or a double bond in the 2:3-position, salts and quaternary derivatives thereof, and a process for their manufacture by splitting off the elements of water from 3-hydroxy-quinuclidine containing a free or functionally converted carboxyl group in the 3-position, and then if desired hydrogenating the 2:3-double bond produced, followed if desired at any stage by conversion of a free carboxyl group into a functional derivative or of a functional derivative into a free or another functionally converted carboxyl group, and/or conversion of a base into a salt or quaternary derivative, or liberation of a base from its salt. Specified functional derivatives include esters, acid chlorides, nitriles and amides, and salts may be formed with e.g. hydrohalic, sulphuric, nitric, phosphoric, thiocyanic, acetic, propionic, malic, oxalic, malonic, succinic, methane sulphonic, ethane sulphonic, oxyethane sulphonic, benzene and toluene sulphonic acids, and quaternary derivatives with reactive esters of lower alkanols, e.g. alkyl halides, dialkyl sulphates, and alkyl esters of organic sulphonic acids.  In examples: (1) 3 - oxy - 3 - carbomethoxy - quinuclidine is added to cooled thionyl chloride, the mixture refluxed and evaporated in vacuo, giving the hydrochloride of 3-carbomethoxy-1-azabicyclo-(2 : 2 : 2)-oct-2-ene, which on hydrolysis with 20 per cent HCl yields the corresponding 3-carboxy compound; (2) 3-carbomethoxy-1-azabicycle - (2 : 2 : 2) - oct - 2 - ene hydrochloride in methanol is hydrogenated using a platinum or palladium catalyst and the resulting 3-carbomethoxy - quinuclidine hydrochloride (characterized as the picrate) hydrolysed with HCl to 3-quinuclidine carboxylic acid hydrochloride, which (3) is refluxed with thionyl chloride and the product treated in chloroform with ammonia gas to give quinuclidine-3-carboxylic acid amide hydrochloride and subsequently the free base and its picrate.ALSO:Therapeutic compositions having sympathomimetic properties and useful for treatment of disturbed peristalsis comprise quinuclidines substituted in the 3-position by a free or functionally converted carboxyl group, and also containing either a hydrogen atom in the 3-position or a double bond in the 2 : 3-position, or salts or quaternary derivatives thereof, together with an organic or inorganic carrier suitable for enteral, parenteral or topical administration. Specified carriers include water, gelatine, lactose, starches, magnesium stearate, talc, vegetable oils, benzyl alcohols, gums, polyalkylene glycols, petroleum jelly, and cholesterol, and the preparations may further contain preserving, stabilizing, wetting, emulsifying or other therapeutic agents, or salts as buffers or osmotic agents.

Abstract: 1,206,001. Sawing. HENRY SIMON Ltd. 18 Jan., 1968 [2 Feb., 1967], No. 2773/68. Heading B5C. [Also in Division B3] A sawing machine for making cuts in arcuate workpieces 140, Fig. 1, comprises a supporting structure 26 carrying a rotatably mounted workpiece-carrying structure 28, and a saw mechanism 27 mounted on the supporting structure for longitudinal movement relative to a workpiece on the carrying structure so that the workpiece can be cut with straight, angled, curved and combination lines as required. The supporting structure consists of braced uprights 30, 31 at their upper ends supporting vertical guideways 42 for bearing blocks 41 for a horizontal shaft 40, the shaft being manually rotatable and formed with pinions 47 engaging racks 44, whereby the shaft is vertically adjustable. The shaft carries a saw support 55 consisting of a pair of flat bearings 56 secured to opposite ends of a plate 57 for mounting a sabre saw 60 having an offset swivelling blade. A sleeve 64 is disposed between the bearings 56 and can be secured to the shaft 40 by a screw 66 passing through a lug, the latter being urged by a spring against a pin on one of the plates 56 to position the saw supporting structure. The latter can be moved against a spring pressure to disengage the saw from the workpiece during skip cutting. The workpiece-carrying support consists of a shaft 85 mounted in bearings 86 on the supporting frame. A pair of hubs 106 are adjustably secured by bolts to the shaft and have flanges 107 to which split work-receiving discs 108 are secured by bolts. The peripheries of the discs and flanges have bolt-receiving inserts 112, 113 by means of which arcuate workpieces 140 may be secured to the machine. The shaft 85 also carries an indexing disc 90 having circumferentially-spaced apertures selectively engageable by a bolt 98 to permit indexing of the workpiece. When the machine is in use without the indexing mechanism, a brake shoe 131 can be engaged with a disc 138 on the shaft by operation of a rod 126 to prevent rotation of the workpiece. Drilling.-A bar 75 is secured to the supporting structures and is provided with horizontally spaced bushings which act as guides for a hand drill used to drill radial holes in the arcuate workpiece.

Title: Improvements in apparatus for use in the manufacture of artificial films and foils
IPC: B29C41/28
Filed: 1932-01-30
Abstract: <PICT:0396398/IV/1> In the manufacture of foils and films, particularly from cellulose derivatives, by depositing a layer of a solution on a moving support, the solution is applied to the support by a resilient roller carrying a layer of the solution.  The resiliency of the roller may be provided by the use of a resilient surface material, by the whole roller being resilient or by a rigid surface mounted on a resilient core and the roller may be resiliently mounted in its bearings.  The resilient surface may be of solvent - resisting rubber and the rigid surface of artificial resin, nickel, chromium, or polished metal such as stainless steel as in Specification 396,723.  The moving support may be of metal, which may be coated with gelatin, or paper, and may have applied thereto a temporary backing, e.g. of wax.  As shown, a band 5 is coated with a solution e.g. of cellulose acetate in acetone by means of a depositing roll 8 and a furnishing roll 11 both of which are rotated clockwise, roll 11 having preferably a greater peripheral speed than 8, and 8 having a greater peripheral speed than the linear speed of the band. Doctor blade 13 controls the quantity supplied.  A micrometer 14 adjusts the depositing device relative to the roll 7. After deposition, the band 5 proceeds through a drying casing 17.  In other Figures (not shown) apparatus is illustrated for applying a second layer of solution which may be e.g. of nitrocellulose and may be coloured, a depositing roll with a rigid surface and resilient core, and a rigid roll mounted in resilient bearings.

The output voltage from the secondary winding 2b of a transformer which has a primary winding 2a'connected to the interrupter contacts 6, 7 of a vibrating reed converter 1 having driving contacts and coil 4, 5, is maintained constant or otherwise controlled by varying the closure time of contacts 6, 7, for example by passing negative feed-back current through rectifiers 8, 9 from secondary winding 2c (or 2b) to an auxiliary driving coil 10. The control may be limited or varied respectively by a battery or non-linear resistor in the connection to one of the coils 5, 10. In modifications the closure time of the vibrator contacts may be varied by electromechanical servo-mechanism energized by the output voltage, or by simple manual control arranged for minimum disturbance of the vibrator screening can; the control voltage may be the difference between the output and a standard from a battery or neon tube suitably amplified, and the vibrator may be self-rectifying.

Abstract: 432,440. Plug-and-socket couplings. CRABTREE, J. A., Endwood, Little Aston Park; Sutton Coldfield. Jan. 30, 1934, No. 3066. [Class 38 (i)] A sliding shield a which normally covers the socket tubes c is displaced against the action of springs g on the correct insertion of a plug, the two pins pressing equally upon the bevelled face a<3>, but an unbalanced pressure tilts the shield laterally about a rib e so that a lug f on the shield engages in the socket tube or against some other part and locks the shield. The shield is therefore not operable by a single pin. In a modification, Fig. 4 (not shown), the shield co-operates with a plug provided with two pins of different lengths and becomes locked if the plug is not properly presented.
