Title: Thermosetting hydrocarbonaceous resinous materials
IPC: C08L95/00
Filed: 1960-12-21
Abstract: A polymerizable composition comprises a partially cured thermosetting hydrocarbonaceous material formed from hydrocarbon pitch and having a softening point between 100 degrees and 250 degrees and 25-60% acetone- or benzenesoluble components together with a compatible, thermosetting resin. The partially cured hydrocarbonaceous material may be prepared by treating pitch with an oxidising agent, e.g. dinitrobenzene or dinitrotoluene, or with phosphorus pentoxide, boron trioxide or red iron oxide. Thermosetting resins mentioned are phenol-aldehyde resins; phenolaldehyde resins modified, e.g. with polyvinyl butyral, rosin, drying oils, or p-tert.-butyl phenol; melamine-aldehyde, urea-aldehyde, and guanidine-aldehyde condensates; alkyd resins and epoxy resins. A list of phenols suitable for preparing the phenol-aldehyde resin is given and includes cashew nut shell oil. Aldehydes mentioned for condensates with the phenols are formaldehyde, acetaldehyde and furfural. Methylene-bridge donors, e.g. hexamethylene tetramine, may be used with the phenol-aldehyde condensates. The compositions may include fillers, e.g. graphite, clay, asbestos, glass filament or cloth, mica, carbon, metal particles, borytes, alumina, titania, silica, nylon, polyesters, carbonaceous fibres produced by carbonising organic fibres, wood floor, or shell flour. In examples (1) coal tar pitch was heated with dinitrobenzene, and the partially cured product was mixed with a phenol-formaldehyde condensate and with hexamethylenetetramine and cured at 260 DEG C. for 4 hours. The cured product was ground, mixed with asbestos, barytes and phenolic resin and pressed to form a brake lining (2) and (3).  The phenol-formaldehyde condensate of example (1) was modified by reaction with cashew nut shell liquid. (4) and (11) Coal tar pitch was heated with phosphorus pentoxide and the product cured together with the phenolformaldehyde condensate of example (1). In examples (5) and (12) the pitch was treated with boron trioxide. In example (6) cashew nut shell liquid, formaldehyde and cresol sulphonic acid were condensed in presence of a partially cured thermosetting material formed from pitch and the product thermoset. (7) The thermosetting resins employed with the pitch product of example (1) were (a) urea formaldehyde resin, (b) melamine-formaldehyde resin and (c) epoxy resin.

Title: New aryl-sulphonyl-thionyl amides and a process for their manufacture
IPC: C07D279/02
Filed: 1960-12-28
Abstract: Sulphur dioxide is obtained by the action of water on aryl sulphonyl thionyl amides of the formula ArSO2N : S-->O, wherein Ar is phenyl or substituted phenyl.ALSO:The invention comprises aryl sulphonyl thionyl amides of the formula ArSO2NSO and a process for their preparation by reacting an aromatic sulphonamide with a thionylating agent, e.g. by refluxing in the presence of anhydrous benzene. The word "aryl" denotes phenyl or substituted phenyl.  Examples describe the reaction of thionyl chloride with benzene-, p-toluene-, p-chlorobenzene-, p-bromobenzene and p-nitrobenzene-sulphonamides to give the corresponding sulphonyl thionyl amides.

Title: Mechanism for turning cigarettes

Abstract: 1,095,529. Turning filter cigarettes. H. H. FOCKE. Oct. 13, 1966 [Oct. 14, 1965], No. 45868/66. Heading A2C. One row Z 1 , of tipped cigarettes Z that are fed with their tips facing one another in two rows on a conveyer 10 of spaced bars 10a, is turned by only two conical wheels 11, 12 which pick up, turn and deposit this row Z 1  while the cigarettes Z remain in continuous motion. The wheels 11, 12, are provided with spaced cigarette carrying grooves 13, 14 respectively which are connected in turn, by pairs of ducts 17a, 17b, and 18a, 18b, to a suction source, a vent to atmosphere, and a compressed air source by means of conventional arcuate recesses on the stationary part of the mounting for the wheels 11, 12. The cigarettes Z of row Z 1  are picked up by, and held while being turned in, the grooves 13, 14 by suction. They are released from the grooves 13, 14 by venting to atmosphere during transfer to grooves 14, and are similarly released from grooves 14 when deposited back on the conveyer 10 between adjacent cigarettes Z to row Z 2 . Air pressure is applied to clean out the grooves 13, 14 during that part of their rotation when they are not carrying cigarettes. The turning mechanism is mounted in a head 35 pivotable about a bearing flange 36 to allow it to be swung away from the conveyer 10 for servicing. The wheel 12 is of smaller diameter, and has a correspondingly smaller number of grooves 14, than the wheel 11. The bars 10a have a point of reduced diameter 16 to avoid obstructing the cigarettes Z as they are swung out of position on the conveyer 10. In another embodiment (Figs. 5, 6 not shown) the grooves (44) of the turning wheels (42, 43) are pivotally mounted and so controlled by cams that they are maintained in axis-parallel relationship with the cigarettes Z over a relatively long period during cigarette picking-up and deposition operations.

[Also in Divisions B1 and B2]  In a pressure-operated dewaterer 10 for fibre pulp suspensions of the type wherein the pulp is pumped from a container 46 to a cylinder 14 from which water is squeezed through perforations 24 into an outer cylinder 28 due to the pressure difference between these cylinders, the stirrer 36 for conveying the pulp to a grinder 12 is driven by an electric motor 42 which controls, via a pulse-emitting relay 44 and an electric motor 34, the position of a valve 32 controlling the discharge of the separated water from the cylinder 28. In operation, variation of the pulp concentration about a predetermined value produces a corresponding variation of the speed of motor 42 and hence a corresponding adjustment of the valve 32 to restore the predetermined value, the latter adjustment varying the pressure in the cylinder 28. Alternatively the valve 32 may be controlled by the conveyer 54 of the grinder 12, in which case the electric motor 56 driving the conveyer controls the relay 44 in a manner similar to that for the motor 42.

Abstract: 1481237 Duplex copying XEROX CORP 28 Oct 1974 [1 Nov 1973] 46499/74 Heading B6C In a process for duplex copying first and second images are formed on a photosensitive surface and then transferred in turn to opposite sides of a copy sheet during a single pass of the copy sheet requiring only one sheet feeding and registration operation and including turning of the sheet about one edge, as it contacts the photosensitive surface. The invention is particularly applicable to electro-photographic copying where latent images I, II, are formed on the photoconductive surface 11 of drum 10 simultaneously from both sides of an original 17 and developed at station C. The trailing edge of a copy sheet 14 is gripped by mechanism (31), Fig. 4 (not shown) and transfer of the first image I under the influence of corona generator 29 is effected to a first side (20), Fig. 4 of the sheet 14. Puffer 40 strips the leading edge and directs the sheet into shoot 41 where the image is fixed using fuser 42. As the drum 10 rotates in the direction of arrow 13, the trailing edge becomes the leading edge of sheet 14 so that side (21) is brought into contact with surface 11, Fig. 6 (not shown). The second image II is transferred using corona generator 44, and the copy sheet 14 stripped by puffer (45), Fig. 8 (not shown) and passed under fuser 47, to delivery tray 48. Detacking corotrons 43, 46 assist the puffers 40, (45), in the stripping operations. The stack 25 may be replaced by roll-feed mechanism (26) and cutter (28), Fig. 2 (not shown). The gripper mechanism (31) comprises two co-operating pairs (32-35), Figs. 4-7 (not shown), and both the developer station C and the cleaning station E may be tripped as the grippers rotate into their area of operation.
