Title: Improvements in the manufacture of methyl vinyl ketone
IPC: C07C45/26
Filed: 1931-07-24
Abstract: Methylvinyl ketone is prepared by reacting monovinylacetylene and water in the presence of a hydration catalyst.  The preferred catalysts are the oxides, hydroxides and salts of mercury, copper, silver, cadmium and zinc; specified salts are mercuric sulphate, acetate, fluoborate, chloride, and arsenate, silver sulphate and phosphate, cadmium sulphate and zinc chloride.  The catalyst is preferably used in association with an acid other than a hydrohalogen acid; acids specified as suitable are sulphuric, acetic, sulphoacetic, phosphoric, arsenic, arsenous, formic, and mono-, di- and tri-chloracetic acids.  In the examples, (1) vinyl-acetylene is shaken in a sealed container with dilute sulphuric acid and mercury sulphate, and the reaction product is neutralized and distilled; methylvinyl ketone is salted out from the distillate; (2) vinylacetylene is bubbled through a solution of mercuric oxide in dilute sulphuric acid at 10-30 DEG  C., and the product worked up as described above; (3) the reaction of example 2 is effected at 60-80 DEG  C., and the vapours from the reaction vessel are led through a condenser, from which an aqueous solution of methylvinyl ketone is withdrawn, while unreacted vinylacetylene is returned to the reaction vessel together with fresh vinylacetylene and water.  Specification 384,654 is referred to.

Title: Manufacture of 1-amino-3-dialkylamino-2-propanols
Filed: 1927-08-12
Abstract: 276,012. I. G. Farbenindustrie, Akt.- Ges. Aug. 13, 1926, [Convention date]. 1-Amino-3-tertiaryamino-2-propanols are made by causing a secondary base to act on a 3-halogen- 2-oxypropylphthalimide, the phthalic acid residue being finally split off, or on a 3-halcgen-2- oxypropylamine.

Patent GB-1170855-A (GB)
Title: Improvements relating to Photographic Apparatus
IPC: G03B29/00
Filed: 1967-05-09
Abstract: 1,170,855. Box cameras. INTERNATIONAL POLAROID CORP. May 9, 1967 [May 13, 1966], No.21546/67. Heading G2A. A box camera is made more compact by bending the light path so that most of it lies parallel to the photo-sensitive film sheet. The examples described and illustrated are adapted for use with "Polaroid" film. The camera is formed as a relatively thin box-like housing having a front wall 12, rear wall 14, side walls 16, and top and bottom walls 18, 20. The Polaroid-type film assemblage comprises a stack of photo-sensitive image-recording sheets 68 in first container 74, and a stack of transfer or image-receiving sheets 70 in a second container 80, the two containers being spaced apart by side members 86 to define a passage 88 between them. At the top of front wall 12 is an objective lens 22, behind which is pivoted a mirror 24. The light path passing through lens 22 is thus reflected to pass through a disphragm 26, 28 and along passage 88 between and parallel to the two sets of photographic sheets. At the farther end of the sheets the light path is reflected again by a prism 92 (or a mirror, as in Fig.4 not shown) to pass through a narrow slit 90 in the inner wall 76 of container 74. Thus as the photo-sensitive sheet 68 is drawn past this slit, the whole sheet is gradually exposed, strip by strip, no shutter being required. At the same time, the image is scanned across the slit 90 by pivoting mirror 24 on its axis, so that the image is maintained stationary relative to the moving sheet. The movements of sheet and mirror are co-ordinated by the mechanism shown in Fig. 7. The image-recording and image-transfer sheets are moved initially by frictional engagement with plates 112, operated by means of a lever 114 from outside the housing, until the sheets enter the nip between rollers 100, 102 driven by a motor 104, after which image transfer takes place in the usual way. A gear-wheel 140, driven from roller 102, carries a cam 138 which is followed by the end of a lever 134. Lever 134 is mechanically linked with the shaft 130 on which mirror 24 is pivoted, thus providing the co-ordination of mirror and sheet movement. The diaphragm is formed by two plates 26, 28 having slots therein which together form the diaphragm aperture 36. The aperture is varied by sliding the plates relative to each other, this sliding movement being controlled by inclined cams 42, 44 on a button 46 mounted outside the housing.

Filed: 1974-05-15
Abstract: 1465180 Cleaning open-end spinning rotors ZINSER TEXTILMASCHINEN GmbH 15 May 1974 [28 May 1973] 21588/74 Headings DID and D1F The rotor 1 of an open-end spinning machine is controlled such that when a thread monitor 9 detects an ends down continuous deceleration of the rotor is initiated and a timer 27 is activated which after a first period sufficient for the rotor speed to permit effective cleaning initiates a pneumatic cleaning operation and after a second period terminates the pneumatic cleaning operation. The initiation occurs during the run down of the rotor at time t 3  and termination occurs at t 5  when the rotor has stopped or alternatively during restarting of the rotor. The cleaning is done by an air nozzle 14 controlled by a valve 8. The rotor is decelerated by a lever operated brake pad 24 while the drive belt 4 is lifted from the drive whorl 3 by a roller, Fig. 2 (not shown).

Abstract: 1,010,030. Controlling clutches; linkwork. FICHTEL & SACHS A.G. May 27, 1964 [June 1, 1963], No. 21977/64. Headings F2K and F2L. Disengagement of a motor vehicle clutch is effected by operation of a variable-ratio linkwork system comprising rods 40, 50 pivoted upon a triangularly-shaped lever 46 so arranged that initial movement in the clutch-disengaging direction requires a relatively large force, which decreases to a relatively small force as disengagement is completed.

This is instead of using the high permeance of a magnetic circuit which is almost entirely ferromagnetic. In the space bounded by the coils and the annular discharge tube a yokeless ferromagnetic core is axially arranged. This core aids in ensuring the necessary field conditions, and saturates at the end of each acceleration period so as to contract the electron orbit. The field relationships may be adjusted by providing an adjustable air-gap in the core. Further air-gaps may be provided.

Filed: 1955-07-29
Abstract: <PICT:0786451/III/1> Hydrocarbon charging stock is thermally cracked when mixed with a hydrogen donor diluent under liquid phase conditions to convert portions of the stock to products of lower boiling point which are continuously withdrawn from the cracking zone as vapour and fractionated.  The charging stock, which may be a crude oil, a distillate or residual fraction therefrom, a coal tar, shale oil, tar, or asphalt, is blended with a hydrogen donor diluent, which is a polycyclic condensed ring aromatic or an aromatic-naphthenic material prepared by partially hydrogenating a thermal tar or catalytic cycle stock, heated in a furnace 4 and passed to a reactor 6.  Conversion products boiling below the initial boiling point of the diluent are removed as vapour by a line 7 to a fractionator 8.  A liquid mixture of diluent, products boiling above the initial boiling point of the diluent, and unconverted constituents of the feed is taken by a line 9 to the fractionator 8.  From the fractionator 8 light gases are removed by a line 10, naphthas by a line 11, heating oils by a line 12, heavy gas oil by a line 14, and a gas oil containing the spent donor diluent by a line 13 to a hydrogenator 18, where the diluent, with make-up diluent admitted by a line 17, is partially hydrogenated, and then returned by a line 2 to furnace 4. In a modification, conversion products and spent diluent are passed as vapours to a fractionator forming the upper part of the cracking reactor, products being separated and the diluent passed to a hydrogenator as before. Specifications 314,871, [Class 32], and 758,413 are referred to.
