Patent GB-901703-A (GB)
Title: Phosphite esters and process of making the same
Inventor: HECKER ARTHUR CALVIN
IPC: C07F9/141
Filed: 1958-08-05
Abstract: A tri-substituted mixed alkyl (or aralkyl) aryl phosphite is obtained by heating a triaryl phosphite with an appropriate saturated monohydric non-tertiary aliphatic alcohol having from 1 to 18 carbon atoms in an amount insufficient to replace all the aryl groups in the triaryl phosphite in the presence of a catalytic amount of an alkali metal alcoholate or hydroxide or alkaline earth metal alcoholate or hydroxide.  Specified triaryl phosphites are triphenyl, tricresyl and trixylyl phosphites and the aliphatic alcohol is preferably a C6-C18 alcohol. Aryl substituted aliphatic alcohols, e.g. benzyl alcohol may also be used.  The catalyst may be added directly or may be formed in situ by adding the corresponding metal, e.g. sodium or potassium, to the alcohol reactant.  Generally, the amount of alcohol used should not be substantially in excess of that required to replace more than two aryl groups in the triaryl phosphite and the reaction temperature normally approximates to the reflux temperature of the reaction mixture.  Examples are given for the production of diiso-octyl monocresyl phosphite and monoiso-octyl diphenyl phosphite and the invention includes such products per se.  The products are useful as stabilizers for polyvinyl halide resins.  Specification 841,890 is referred to.
Patent GB-995155-A (GB)
Title: Production of dibenzothiophene and dibenzofuran derivatives
Inventor: MCCALL ERNEST BRYSON
IPC: C07D333/76
Filed: 1962-06-29
Abstract: A dibenzothiophen or a dibenzofuran substituted by an aromatic group is prepared by heating a dibenzothiophen or dibenzofuran with an aroyl peroxide.  The dibenzothiophen or dibenzofuran starting material may contain other substituents which must be substantially inert during the reaction, e.g. halogen atoms. The aromatic group that is introduced during the process is generally an aromatic hydrocarbon group, which may however be substituted, e.g. by halogen atoms.  Compounds containing up to four aromatic groups are usefully prepared by this process, although the number can be higher.  Where the product is a dibenzothiophen or dibenzofuran containing more than one aromatic group, one or more of these may have been present in the starting material. The process may conveniently be operated by adding the aroyl peroxide to the starting material at a temperature at which the peroxide decomposes to give the required aromatic radicals at a practical rate.  The optimum temperature is usually in the range 50-200 DEG C. The quantity of aroyl peroxide employed relative to the starting material will depend on the number of aromatic groups to be introduced. The product of the process may be a mixture of isomers which may be separated or used as such. An example describes the preparation of an isomeric mixture of monophenyldibenzothiophens. The compounds possess good thermal stability and can be employed as functional fluids.

Abstract: 158,939. Goodyear, C. E. Oct. 14, 1919. Vehicle lamps.-Automobile and like lamps having bodies consisting mainly or entirely of glass or equivalent material are secured to their supporting-means by expansible and contractible collars. The bodies, except for the light-emitting portions, may be rendered more or less opaque either in the course of manufacture or by paint or other coating. Parts of the bodies may be internally or externally silvered to act as reflectors, and parts of the light-emitting portions may be coloured. The light-emitting portions may be of less thickness than the lamp body. Rubber or other vibration-absorbing medium may be incorporated in the means carrying the lamp bodies. In the lamp shown in Fig. 1, the glass body a is formed with a neck b having a flange c engaged by a closure member d on a slotted frame i which is adapted to be secured to the car lamp-bracket by a screw k and locking-nut l. The member d carries a standard electric-bulb holder g and is secured to the flange c by a channel-sectioned clamping-collar e tightened by means of a screw f. The flange, closure member, and clamping-collar may be formed with engaging depressions to prevent relative rotation. In another form, the closure member is riveted to a dished plate having a perforated rim by which it is attached to the car body or mud-guard. In Fig. 7 the lampbody is shown fitted with a disc t acting as a continuation of the reflector and is mounted on a bracket u. In the form shown in Fig. 9, the electric-bulb holder is mounted in a metal shell or casing x which is clamped to a rib 3 on the body. The shell may be silvered to act as a reflector. The Provisional Specification states that the neck of the lamp-body may be threaded to receive the lamp-holder and that the body may be of stream-line formation and provided with external ribs or corrugations.

Rotation of shaft 5 and movements of the pistons as controlled by valves A, B, (Figs. 4-6 not shown), produce adjustment of valves 29, 29<SP>1</SP>. However, a flap angle of less than 15 degrees, e.g. during cruising of the aircraft, maintains valve 29, 29<SP>1</SP> closed; on takeoff the valves A, B are as shown in Fig. 3 and provided the flap angle is greater than 15 degrees the valves 29, 29' are opened accordingly. On landing or should one pressure source fail on take-off, the valves 29, 29<SP>1</SP> are opened to a greater degree per degree of flap angle than on normal take-off. A pilot operated solenoid valve 3 vents the system to close the butterfly valves in an emergency.

Title: Device for the delivery of flat items from a stack of flat items
IPC: B07C1/04
Filed: 1968-05-27
Abstract: 1,216,876. Feeding sheets. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. 27 May, 1968 [26 May, 1967], No. 25260/68. Heading B8R. Sheets 6, stacked on edge are removed from the pile by belts 3 having suction ports 3<SP>1</SP> cooperating with suction trough 1, the sheets being forwarded to a supplementary separation device comprising suction trough 2 which is operable to prevent the forwarding of more than one sheet at a time. A sheet arrives beneath trough 2 in advance of the set of ports 3<SP>1</SP> which lifted it from the pile (due to the detour of belt 3 around rollers 8, 9 and 10) and consequently there is a time delay between the arrival of a sheet and its removal by the ports 3<SP>1</SP> from the region of trough 2. If more than one sheet is separated the additional sheet (or sheets) remains behind when the first sheet is removed from beneath trough 2, thus causing a continuing blocking of the light to photocell 23<SP>11</SP> resulting in the application of fingers 20 to the pile preventing further separation therefrom. The additional sheet (or sheets) is removed by the next set (or sets) of parts 3<SP>1</SP> passing beneath trough 2. A rotary brush 17 guides the sheets beneath the trough 2 where they are arrested momentarily by a reciprocating stop 15. In an alternative embodiment, a separate belt may be provided to co-operate with each trough, the belts being timed to ensure a delay between the arrival of a sheet beneath trough 2 and its removal from this position. Instead of fingers 20, either the vacuum supply to trough 1 may be cut off or the drive to the belt associated with this trough may be disengaged. The wall 15 may be replaced by a fixed wall and wall 16, together with a further parallel guide wall may be movable to direct sheets momentarily against the wall before presenting them to the trough 2. Vacuum strippers 11 and 12 may be provided at the exit of each of the two separators.

Abstract: 1353950 Hydrocracking; luboil bases UNIVERSAL OIL PRODUCTS CO 19 April 1971 [2 April 1970 (2)] 25822/71 Heading C5E Lubricating oils of V.I. higher than 100 are obtained by cracking two feedstocks. The first feed, e.g. a deresined cylinder stock, is mixed with hydrogen and cracked over a catalyst (6), the product is separated into vapour and liquid in a hot separator (8); the vapour from 8 is mixed with the second feed, e.g. a wax distillate, and cracked over a catalyst (12), this product is separated into vapour and liquid in a cold separator (17); part or all of the vapour from 17 is recycled as a part of the hydrogen feed to 6; the liquid from 8 is separated into liquid and vapour at a reduced pressure, e.g. in a hot flash 11, the liquid from the hot flash is further separated, into a first lubricating base stock (21) and a vapour, e.g. in a fractionating column 20; the vapour phases from the fractionator and the hot flash and the liquid phase from the cold separator are combined and separated into vapour and liquid at reduced pressure, e.g. in a cold flash 23, and the liquid from the cold flash is further separated, e.g. in a fractionating column 26, to obtain a second lubricating base stock (27). In a modification (Fig. 2, not shown), a hot separator (18<SP>1</SP>) is interposed between the second reactor and the cold separator, and it is the vapour from this hot separator that goes to the cold separator; the liquid from this hot separator is separated into liquid and vapour in a hot flash (24<SP>1</SP>), and the vapour from 24<SP>1</SP> is mixed with the vapour from the first hot flash and the liquid from the cold separator and separated in a cold flash (22<SP>1</SP>); the liquids from 22<SP>1</SP> and 24<SP>1</SP> and the overhead distillate from the bright-stock fractionator are combined and separated in a fractionating column (33), and the bottoms from this column are combined with a sidestream from the bright-stock fractionator to provide the second lubricating base stock. The second cracking zone may be operated under less severe conditions, that is a lower temperature or a higher space velocity, than the first. Part of the heaviest material from the first hydrocracking zone may be recycled. The catalysts in the two cracking zones may be the same or different and may contain a transition metal of Group VI or Group VIII, compounded with a porous carrier material, e.g. alumina, silica, titania, zirconia, magnesia, alumina-silica, silicamagnesia, alumina - silica - boron phosphate, silica-zirconia, mordenite, faujasite or an aluminosilicate molecular sieve, and may be halided. If the feedstocks have not been dewaxed, the products may be.

Filed: 1961-07-17
Abstract: 951,221. Wire-stitching machines. T. B. CLERK. (T. W. & C. B. Sheridan Co.). July 17, 1961, No. 25863/61. Heading B4C. [Also in Division B6] A stitching-machine having continuously operated automatic stitching heads, is provided with means for de-activating said heads without stopping the movement of their parts, each time the heads fail to receive a complete article to be stitched. Each stitcher head is supplied with a continuous wire strip W normally fed downwards one stitch or staple length each time the head operates by means of reciprocating grippers 23, 24. Gripper 24 is pivotally mounted on pin 25 and urged towards gripper 23 by a blade spring 27. Known mechanism for opening the grippers at the end of their downward stroke and holding them open during their upward stroke is provided. On failing to receive a complete article, such as a book signature, the head is de-activated during its downward stroke by a spring-loaded lever 30 pivoted to the gripper 23 and rotated to engage a pin 26 on the gripper 24, whereby the grippers are latched open. Hence, no wire is fed and no staple formed during this downward stroke. In this case said known mechanism acts to lift the pin 26 free from the lever 30 at the end of the downward stroke, so that the spring 33 returns the lever to its unlatched position and the grippers are free to re-engage the wire at the commencement of the next cycle. On sensing an incomplete or missing book signature, calipering means activate a solenoid, after a suitable time delay, whereby a finger 35 is pivoted to engage one arm 34 of the lever 30 to latch the grippers open when said missing or incomplete signature is positioned beneath the heads. Alternatively, the armature of the solenoid engages the arm 34 direct. The signatures are fed intermittently beneath the stitching heads by reciprocating bars 44, 45a (see Division B6), positioned above and below the signatures, respectively. The bar 44 carries spring-loaded grippers 45 adapted to press the signatures against the bar 45a during feeding movement and be retracted therefrom by mechanism 46 during return movement.
