Title: Improvements in the manufacture and production of vinyl ethers
IPC: C07C43/16
Filed: 1935-09-14
Abstract: Vinyl ethers are manufactured by reacting acetylene at elevated temperatures in the presence of a strongly alkaline reacting substance as catalyst with carbohydrates or such derivatives thereof as still contain at least one free reactive hydroxyl group and are stable in the presence of basic substances above 100 DEG  C., e.g. tetramethylglucose or preferably carbohydrate derivatives which are acetalized to a considerable extent, such as b -diacetonefructose, monoacetone-glucose or the mixture of b -diacetone-fructose and diacetone-glucose formed by treating cane sugar with acetone and sulphuric acid, or the corresponding methylene, ethylidene or benzylidene acetals.  The acetylene, diluted with inert gases, e.g. nitrogen or hydrogen, may be reacted under normal or increased pressure with the sugar or its derivatives dissolved or suspended in a solvent or diluent or on the fused compounds themselves.  As catalysts may be employed the oxides, hydroxides, alcoholates or phenolates of the alkali or alkaline-earth metals.  The products may be employed as softening agents for lacquers and plastic masses, or may be hydrogenated to the corresponding ethyl ethers, which may be similarly employed. The vinyl ethers may also be polymerized, as such, in solution, or in emulsion or suspension, if desired together with other vinyl compounds, e.g. vinyl methyl or ethyl ether, vinyl octodecyl sulphide, substituted aromatic vinylamines, vinylcarbazole, acrylic acid esters, styrene, vinyl halides, vinyl esters, e.g. the acetate, acrylic nitrile or unsaturated ketones, e.g. vinyl methyl ketone.  The polymerization products may be employed, alone or mixed with other substances, e.g. natural or synthetic resins or highly polymerized compounds, fillers, softening agents or dyestuffs, for the preparation of lacquers, films or foils.  In examples: (1) b -diacetone-fructose is treated in a shaking autoclave with acetylene diluted with nitrogen, in the presence of potassium hydroxide, yielding 1 - vinyl - 2 : 3 : 4 : 5 - diacetone-fructopyranose-(2 : 6); the product may be polymerized, and solutions of the polymer may be worked up into films and coatings; (2) the reaction of (1) is carried out in butanol solution, vinyl butyl ether being formed as a bye-product; (3) monoacetone-glucose is dehydrated by adding toluene and distilling off a portion thereof, and the residue is treated as in (1); (4) the mixture of b  - diacetone - fructose and diacetone - glucose, obtained by simultaneously splitting and acetalizing cane sugar, is dehydrated by adding butanol and distilling it off, and is then treated with acetylene diluted with nitrogen, in the presence of potassium hydroxide; the product may be polymerized and the polymer used for preparing coating agents; the corresponding ethylidene, benzylidene and methylene acetals may be similarly treated. Specification 378,544 is referred to.

Abstract: 1496549 Mounting clutch discs on hubs DAIMLEK-BENZ AG 16 June 1975 [24 June 1974] 25599/75 Heading F2U A clutch disc 10, 11, 12 is resiliently-mounted on a hub 17, 27 by at least three spring stages 13, 14, 15 and 16 of progressively harder characteristics, the friction damping devices comprising a damping device 28 for the idling range provided with a friction disc 28a, and first and second main damping devices 30, 31 provided with friction discs 33, 44 and control plates 32, 43 respectively, the arrangement being such that the disc 28a acts with the plate 32 so that at the commencement of compression (at A in Fig. 5) of the second stage spring 14 the first main damping device commences to act instead of the idling damping device, and the second main damping device commences to act (at B) additionally to that of the first within the range of action of the second stage spring. As shown, the idling damping device 28 consists of a friction disc 28a and a spring 29. The first main damping device 30 consists of a control plate 32 and a pair of friction discs 33 pressed by a pair of springs 34, the control plate being provided with an upturned edge 40 for co-operating with a window 38 and a lug 41 for co-operating with a recess 42. The second main damping device 31 consists of a control plate 43 and a pair of friction discs 44, the control plate being provided with an upturned edge 50 for co-operating with a window 47 and a lug 51 co-operating with a recess 52. As shown in the graph, for the idling range L the first stage spring 13 is compressed and the damping by the disc 28a is very slight. In the range I the second stage spring 14 is also compressed and the control plate 32 is held by the window 38 to allow the clutch disc 10, 11, 12 to compress a first control spring 36; the disc 28a ceases to act and because the spring 36 is precompressed a step S1 occurs and damping is represented by shaded areas 57. In the range II the control plate 43 is held by the window 47 to allow the clutch disc 10, 11, 12 to compress a second control spring 45 and because the spring 45 is precompressed a second step S2 occurs and damping is represented by shaded areas 58 which are added to the areas 57. The third and fourth stage springs 15, 16 come into operation in ranges III and IV with the damping effect remaining added as shown by areas 57, 58 and the idling friction damping device remaining out of action.

Abstract: 927,144. Making cams. PERKIN-ELMER CORPORATION. July 14, 1961 [July 22, 1960], No. 25619/61. Class 83 (2). [Also in Group XXIV] In a method of making a cam, a metal strip is secured to the outer surface of a cam blank to form a cam surface. A mould comprises a base-plate 10 having a spigot 13 and a middle plate 12 having an opening larger than the cam form. A suitable parting agent is applied to the plates but not to the surface defining the cam outline in plate 12 or to the spigot diameter and to a master cam 18. The plates are screwed together, the cam 18 screwed to the plate 10, and the gaps 14, 15 filled with a metal-loaded epoxy resin to provide the spigot 13 and the cam outline in the plate 12 with moulded surfaces 34, 30. After hardening the cam 18 is prised from the mould by the screws in the plate 10 after fitting a plate 22 over the assembly to protect the cast faces. The plates 10, 12 are separated, cleaned, coated with a parting agent and re-assembled. A roughly-shaped cam blank 36 is screwed to the plate 10 and a flat flexible metal strip 48 of a width equal to the thickness of the finished cam inserted into the cavity 40 against the mould face 30. Metal-loaded epoxy resin is injected between the strip 48 and the blank 36 and into the central cavity 42. After setting, the faces are cleaned and the completed cam form ejected by screws in the plate 10 engaging the blank 36. In a modification, metal strip may be wrapped around the periphery of an undersize cam and suitably secured by screws or resin. In a further modification the cam may be cast with an outer metal loaded resin without a metal strip (see Group XXIV).

Abstract: 653,419. Stopping shafts in predetermined positions. PHILIPS ELECTRICAL, Ltd. Oct. 1, 1948, No. 25621. Convention date, Oct. 4, 1947. [Class 80(ii)] [Also in Group XL(c)] Stop-pawls 5, angularly and axially spaced about a rotary shaft 1 on rockshafts 6, and each cooperating with one of a number of peripherally notched discs 2 arranged along the shaft, to stop the latter in predetermined angular positions, as for tuning a radio receiver or transmitter, are positively lifted out of their notches 3 in the stop-discs 2 by the movement of the pawl-selector mechanism, which comprises a single annular cam surface 10 on a coaxial rotary selector-wheel 9 and having a single gap or depression which in an appropriate set position, admits a selected one of a number of coplanar pins 8, one on each rockshaft 6, thereby permitting a spring 17 to act on a radially-guided member 13 (shown axially out of place) so that its curved undersurface 14 urges the pin 8 down into the gap, thus causing the corresponding pawl 5 to enter its stop-disc notch 3 to stop the shaft 1 in the selected position. On the first movement of the selectorwheel 9 towards a new position, one of the bevelled sides 11 of the cam-gap positively cams out the operative pin 8, lifting the corresponding pawl 5 out of its stop-wheel notch 3, which frees the shaft 1 for rotation until arrested in the new position by a selected pawl 5. The idle pins 8 ride on or near the cam surface 10 under the influence of a spring or stop (not shown). In Fig. 2, not shown, the slot-guided member 13 and spring 17 are replaced by a single bent-wire spring.

[Also in Division F2] The flow of gas from an inlet 5 to a main burner outlet 6 and a pilot burner outlet 7 is controlled by a valve arrangement including a minimum gas-pressure cut-off closure 8 cooperating with a seat 9 and disposed on a shaft 10 carrying a diaphragm 11 and a pressureregulating closure 24 co-operating with a seat 25 in series flow with seat 9. The diaphragm 11 is acted upon by gas downstream of seats 9, 25 in opposition to a spring 12 and atmospheric pressure acting beneath the diaphragm. A second diaphragm 19 is attached to the stem 10. A spring-loaded valve 20 by-passes the seats 9, 25. The valve casing 1 has three removable covers 2, 3, 4. The valve arrangement also includes a flamefailure valve-closure 27 coacting with a seat 26 in the flow path to the main outlet 6, and a closure 29 coating with a seat 28 in the flow path to the pilot outlet 7. The closures 27, 29 are attached to telescopically disposed elements 30, 31 which are loaded away from each other by a spring 32, the element 30 being connected to an armature 33 and the element 31 incorporating an electromagnet 34 energized by a thermosensitive device (not shown) activated by the pilot burner. The element 31 is connected to a spring-loaded push-button 35 and the latter is also connected to the by-pass valve 20 by a spring 38. Upon pressing the button 35 the valve 20 and closure 29 are unseated whereupon gas flows to the pilot outlet 7 and into diaphragm chamber 15; the electromagnet 34 is energized and holds the armature 33 so that upon releasing the button 35 the closure 27 is unseated. A stop prevents the element 30, 31 from moving to seat closure 29. The pressure in diaphragm chamber 15 builds up to open the closure 8 and cause closure 24 to function as a pressure regulator.
