Abstract: 513,119. Polyvinyl acetal resins. KODAK, Ltd. (Eastman Kodak Co.). March 22, 1938, No. 8828. [Class 2 (iii)] Polyvinyl acetal resins are prepared by reacting polyvinyl alcohol, or a polyvinyl ester under saponifying conditions, with a halogensubstituted aliphatic compound which reacts with the polyvinyl body to form an acetal, e.g. an aldehyde. Saponifying conditions may be produced by reacting in an alcohol, e.g. methyl, ethyl, or iso-propyl alcohol, with or without water or dioxane, with a catalyst, e.g. hydrochloric, sulphuric, trichloracetic, or organic sulphonic acids. Other acetalysis catalysts are zinc chloride and phosphoric acid. There are specified :-polyvinyl esters-acetate, chloracetate, propionate, butyrate ; acetal-forming bodies-mono- or di-chloracetaldehyde, chlorderivatives of propionaldehyde and butyraldehyde, the corresponding bromine derivatives, monochloracetaldehyde diethyl acetal. The acetal-forming body is preferably a saturated aldehyde containing one or more chlorine or bromine atoms in the alpha position or an equivalent compound such as alpha:#-dichlorethyl ether or alpha:#:#-trichlorethylether. There may also be present a second acetal-forming body, e.g. formaldehyde, acetaldehyde, propionaldehyde, butyraldehyde, paraldehyde, acetaldehyde, diethyl ether. The resins may be plasticized with tributyl phosphate, triphenylphosphate, tricresyl phosphate, diamylphthalate, dibutyl phthalate, di- and tri-glycerol esters, e.g. the acetins, propionins and butyrins, and monochlornaphthalene. The resins may be used in moulding compositions or sheets, e.g. photographic films, interlayers for safety glass. Examples detail the preparation of polyvinyl chloracetaldehyde, acetaldehyde-chloracetaldehyde and acetaldehyde-bromacetaldehyde acetal resins.

Title: Process for the conversion of olefin hydrocarbons
IPC: C07C2/74
Filed: 1937-03-25
Abstract: Olefines are simultaneously polymerized and hydrogenated by treatment with hydrogen, a hydrogenating catalyst, and a polymerizing agent comprising a phosphoric acid and a solid adsorbent.  Suitable catalysts are the oxides and sulphides of chromium, molybdenum, tungsten, and uranium.  The reaction temperature is usually below 300 DEG  C. and the pressure 100 atmospheres or less.  The process is particularly applicable to the production of iso-paraffins boiling within motor fuel range from branched-chain mono-olefines present in oil cracking gases. According to an example 100 parts of isobutylene are heated for 12 hours at 275 DEG  C. in 75-100 atmospheres of hydrogen in the presence of 2,5 parts each of molybdenum oxide and a solid phosphoric acid polymerizing agent, and a 50 per cent yield of iso-octane is obtained.  The polymerizing agent is made by mixing 70 parts of pyrophosphoric acid with 30 parts of kieselguhr, calcining at 275 DEG  C., and grinding.

Patent GB-801248-A (GB)
Title: Solvent dewaxing of petroleum oils
IPC: C10G73/06
Filed: 1957-03-19
Abstract: In the dewaxing of petroleum oils by adding a solvent containing up to 6 C atoms per molecule, chilling by evaporating some of the solvent to produce a slurry and separating wax from the slurry, a non-reactive gas is bubbled through the solvent-oil solution during chilling, at a rate whereby the amount of gas introduced during chilling is 0.5-1.5 volume per cent of the amount of solvent vapour evaporated, both measured under standard temperature and pressure. The process produces wax crystals of more uniform size with less tendency to clog the filters used for separating the wax.  Suitable gases are carbon dioxide, methane or nitrogen; also air if a non-inflammable solvent is being used.  A preferred solvent is propane, used in a ratio of 1.5-3.5 : 1 by volume of oil.  The dry gas is stored under pressure and released through a throttling valve through nozzles or similar distribution means into the bottom of the chiller.  Preferably at least two chillers are employed to enable the process to be operated continuously.

Title: Machine for Producing Lined Cartons
Inventor: SCULLY JOHN WILLIAM
IPC: B31B7/32
Filed: 1967-02-24
Abstract: 1,179,464. Making lined cartons. PNEUMATIC SCALE CORP. 24 Feb., 1967, No.9015/67. Heading B5D. In a machine for producing lined cartons, a lining sheet 14 is cut from a web 16, wrapped around one of an assembly of intermittently rotating forming blocks 12 at station A and sealed to form a bag. At station C a prescored carton blank 42 is fed to and erected around the lining bag after which the lined carton is stripped from the forming block 12 and tipped on to a conveyer 64 leading to a line of packaging machines. The web 16 of lining material is withdrawn from a roll (18), Fig. 6 (not shown), and continually fed over rolls (20), (22), the latter of which is driven by a ratchet and clutch mechanism (24), over a roll 68 at a gluing station 30, and over a glue drying plate 72 to a gear and rack mechanism (32), Fig. 5 (not shown), which intermittently advances one length of lining material. A movable suction manifold 50 with suction elements 52 is connected to a vacuum system and transfers carton blanks from a stack 44 into the bight of feed rolls 46, (48), Fig. 4 (not shown), on to a conveyer 56, along which the blanks pass a gluing station 60 before being wrapped around the forming blocks 12. A photo-electric scanner 118, 120 detects a surplus of lined cartons on conveyer 64 and operates a circuit which discontinues the feed of carton blanks 42 and lining material 16 but allows partially formed cartons to be completed and tipped on to the conveyer: a time delay relay (122), (PE), Fig. 2 (not shown), is actuated by the scanner to discontinue the vacuum to the suction manifold 50 by means of a valve 128 in a vacuum line 126 which is closed by solenoidoperated pilot valve 142 (SVI, Fig. 2) connected in a compressed air line 130. The supply of lining material is discontinued when a spring and pivotally mounted finger 174, normally in contact with a carton blank, descends to actuate a switch 180 which de-energizes a relay (186) and thereby disengages the gear and rack mechanism (32). Simultaneously, the switch 180 energizes a solenoid-operated valve 214 in a compressed air line 216 to move a stop 94 attached to the piston (222) of an air cylinder 224 to disengage the ratchet and clutch mechanism (24). Similar means also stop the application of glue to the carton blanks 42 and the web 16 of lining material by withdrawing a roll 158 and roll 68 from engagement with glue applying rolls. Means for discontinuing the transfer of carton blanks and the feeding of lining material independently of the scanner 118, 120 are actuated by a switch (282), Fig. 3 (not shown), and provision is made for the separate feeding of carton blanks 42 or lining material.
