Title: Improvements in method of making polyurethane prepolymers and polyurethane thread produced by said method
IPC: C08G18/10
Filed: 1959-12-30
Abstract: A method of making a prepolymer comprises heating, at a temperature of 90 DEG -100 DEG C. for a period of from 90-120 minutes, a mixture of a polyester derived from a glycol and a dicarboxylic acid, said polyester having a molecular weight of from 500 to 5,000 and an acid value less than 6, with from 1,8-2,1 moles of an aromatic diisocynate, until the reaction is substantially complete, as evidenced by the fact that a substantially constant viscosity is achieved, to form a soluble, uncured, liquid material which is an essentially linear polyurethane having terminal isocyanate groups, and thereafter heating such linear polyurethane in an inert atmosphere at a temperature of 90 DEG -100 DEG C. for a period of from 48-196 hours, to provide a liquid, uncured, essentially linear, soluble polyurethane having terminal isocyanate groups, which is capable of being cured in the form of a thread, by subsequent curing action of an aliphatic diamine and water, characterized by a permanent set of from 2%-10%.  The conversion to a solid thread is effected in two stages, the diamine first reacting to form a composite thread having a fluid core of uncured prepolymer and an outer shell cured to the solid state.  The action of water, preferably under pressure, e.g. 50-150 pounds per square inch causes the liquid core to set. Suitable diamines are ethylene diamine, hexamethylene diamine, 1, 4-diamino-cyclohexane, 3, 31-diamino-dipropyl ether and diaminodibutyl sulphide.  Preferably the setting bath also contains an anionic or nonionic wetting agent. In Examples (1) a polyester (M.W. 2070) from adipic acid, ethylene glycol and 1, 2-propylene glycol was reacted with methylene bis (p-phenylene diisocyanate) for 48 hours at 90 DEG -95 DEG C. in a nitrogen atmosphere. The prepolymer was extruded into a 3% aqueous ethylene diamine bath at 135 DEG F. and then cured in a water bath at 140 DEG F. and 100 lbs. per square inch pressure.  The product had a permanent set of 4%; (2) for comparison a thread in which the heating of the prepolymer reaction mixture lasted six hours was prepared and was found to have a permanent set of 38%.  Other examples illustrate prepolymer heating times of 48, 120 and 170 hours, and for comparison, 1 1/2 , 6 and 24 hours.  Reference has been directed by the Comptroller to Specification 847,673.

Abstract: 1537029 Educational appliances THOMAS SALTER Ltd 17 Sept 1976 [29 Oct 1975] 44588/75 Heading G5G A question and answer device indicates the correct answer to a multiple choice question on a sheet (not shown) placed in a recess 14 by allowing a ball inserted in an entry hole 8 to emerge from a selected exit 12, the exits being lower than the entry hole (Fig. 1, not shown). As described to select a question a PVC belt 1, which passes from a roller 2 over the open side (facing exits (2)) of a channel 4 to a roller 3, is advanced using knobs 15 and 16 until the number of the question, the numbers being printed on the belt, appears in a window 7. At this position a hole in the belt will be aligned with one of the exits to correspond to the correct answer. Thus a ball inserted through the hole 8 passes down passage 9 at a rate controlled by tongues 10 to the channel 4 to emerge through the hole in the belt at an exit to indicate the correct answer. A container 13 for the ball when not in use, and for the storage of pegs, for engagement with studs (not shown) for a student to select his answer and for scoring, is provided. In an alternative embodiment (Fig. 5, not shown) an endless belt having holes therein is supported by a rod at the upper end of the housing. In this embodiment a cursor is connected to the belt and is operable to move the belt as it is moved along the recess 14. Thus a question may be selected by aligning the cursor with the question on a sheet inserted in the recess. Spare question sheets may be stored under the housing by means of tabs formed on wedge-shaped legs, the legs serving to support the housing at an angle.

The groups of objects are transferred by gripper strips 11a-11d mounted on a reciprocating frame. An empty container, or a container B having only a single group of objects left may be pushed by the frame on to the conveyer 4 to become a carton. A row of full containers may be fed from a conveyer 7 on to a conveyer 6 parallel to, and moving stepwise with but in the opposite direction to, the conveyer 5. The frame then feeds individual cartons from the conveyer 6 to the conveyer 5. If there is an even number of sorts the individual sorts are disposed in two successive storage containers at a time in the feed sequence. In another embodiment, Fig. 5, not shown, the cartons are fed between a plurality of conveyers each holding containers having a single different sort of object. Some of the conveyers are only moved each alternate step.

Filed: 1972-09-27
Abstract: 1444348 Book covers; indexing books R GASPAR 27 Dec 1973 [27 Sept 1972] 44650/72 Headings B6A and B6E The individual pages of a book are provided with marks each including at least one element that points in a different direction on consecutive pages so that the elements appear to rotate when the pages are thumbed through, thereby facilitating the location of a desired page. As shown in Fig. 1, the directional elements comprise a plurality of lines 2 on each page, the mark on each page including a field 3 indicating whether the elements are printing upwards or downwards. The marks may be at the same position on the margin of each page, or staggered down the margins. The field may be separate from the directional elements, Fig. 2, and be made up of lines which change orientation to indicate different sections of a book as described below. Various examples of suitable marks are given, Figs. 3 to 6 (not shown). In a particular embodiment, Fig. 7, the directional elements 2 appear in a light field against a dark mark 4, the marks being staggered to produce oblique lines 6, 14 visible from the edge of the closed book denoting sections of the book. Additional elements denote the particular section in which the mark lies and these additional elements are shown on an index sheet for instance on the back cover 7 of the book at 12, together with the directional elements at 17 relating to specific pages. In this way a grid is produced which indicates the appearance of the mark present on a desired page, and the section of the book in which the desired page is to be found. The oblique lines may be distinguished by different colours, textures, lengths or widths. Thumbing through the leaves is facilitated by the provision of foam rubber pads 19 on the inside of the cover and in the middle of the book. Book Covers.-Where the book has hard covers, flicking of the pages is facilitated by providing a flexible joint 20, Fig. 7, between the two rigid parts of one cover. One part 22, Fig. 9 has a part-circular cross-sectional groove, and the other 21, a tri-angular cross-sectional groove, the grooves accommodating a correspondingly shaped link 23, of rubber. A heel 24 prevents the parts being bent inwardly and the gap 26 is filled with compression resistant material. Similarly, on the other side of the joint, the gap 25 is filled with stretch resistant material.

Abstract: 1,129,516. Magnetic separators. M.E.L. EQUIPMENT CO. Ltd. 11 Aug., 1966 [26 Oct., 1965], No. 45267/65. Heading B2J. A magnetic filter for removing ferromagnetic particles from a fluid comprises an inner core 1 consisting of a series of co-axial discs 2 of soft ferromagnetic material spaced apart by cylindrical permanent magnets 3 having like poles opposing each other so that adjacent discs 2 form pole pieces of opposite polarity, and an outer cage 12 fitted round the core 1 and consisting of a series of spaced, co-axial annular members 13, Fig. 1, or 26, 27, Fig. 2, of soft ferromagnetic material which are each located adjacent a respective one of the discs 2 to form an extension of the pole piece formed by that disc so that when fluid containing ferromagnetic particles flows past the members 13 or 26, 27 such particles are attracted to these members, the core 1 and the cage 12 being capable of being separated from one another by axial movement of one relative to the other. The discs and the magnets 3 are supported on a tube 4 and held between plates 5, 6 which are clamped between nuts 7 and a collar 8 secured on a hollow tie bolt 9. Rods 10, 11 securing the collar 8 to the bolt 9 form a handle. As shown in Fig. 1, the annular members 13 are in the form of plates substantially co-planar with the discs 2 and are mounted on a sleeve 14 of non-magnetic material between its flanged upper end 15 and its turned lower end 16, the plates being held in assembled relationship by four tie bolts, of which one is shown at 17, with sleeve-shaped spacing elements 18 surrounding the bolts between the plates. Each pair of bolts is connected to a U-shaped handle 19. The sleeve 14 has a sliding fit on the discs 2. The core 1 and the cage 12 are housed with a sliding fit in casing 24. The plates 13 may be formed at their edges with recesses (25), Fig. 2 (not shown), so that the length of the outer periphery of each pole piece extension is increased thereby increasing the separation of ferromagnetic particles from the fluid as the latter passes the edges of the plates 13. The recesses in one plate are preferably staggered relative to those in adjacent plates. To clean the filter the cage 12 and the core 1 are drawn apart axially by means of the handles 10, 11 and 19 whereby the plates 13 of the cage will no longer be magnetised and the ferromagnetic particles collected on the edges of these plates will fall off or can be readily removed as by flushing. In Fig. 3, the extensions of the pole pieces are each formed by a pair of rings 26, 27 made from corrugated strips which produce fin-like radial projections, Fig..4 (not shown), on the outer side of the sleeve 4. The rings 26, 27 of each pair of corrugated rings have the same polarity, being separated by a spacing ring 28 of soft-ferromagnetic material substantially coplanar with the associated disc 2 of the core 1. The fin-like projections may be in line or staggered.
