Patent GB-959286-A (GB)
Title: Improvements in or relating to bis-phenols
Filed: 1960-09-07
Abstract: The invention comprises bis-phenols of formula: <FORM:0959286/C2/1> wherein R and R1 are alkyl groups containing differing numbers of carbon atoms, R and R1 together containing from 11 to 23 carbon atoms. They are used in the preparation of epoxy resins (see Division C3). The bis-phenols are prepared by condensing 2 moles of phenol with 1 mole of an unsymmetrical ketone such as 2-tridecanone, 2- or 3-pentadecanone, 2-heptadecanone, 2-tricosanone, 3-tetradecanone, 3-nonadecanone and 4-eicosanone.  In an example a mixture of phenol, methyl undecyl ketone and beta-mercaptopropionic acid is heated to dissolve the ketone, cooled to 30 DEG C. and hydrogen chloride is bubbled into the mixture which solidifies at the end of the reaction. The product (2, 2-bis(4-hydroxyphenyl)-tridecane) is washed with water and petroleum ether and dried by azeotropic distillation.  2, 2-Bis(4-hydroxyphenyl)-nonadecane and 3, 3-bis(4-hydroxyphenyl)-tetradecane are similarly prepared.ALSO:Epoxy resins having improved adhesive strength at cryogenic temperatures are prepared from bis-phenols of formula: <FORM:0959286/C3/1> wherein R and R1 are alkyl groups having differing numbers of carbon atoms and R and R1 together contain 11-23 carbon atoms (see Division C2). In an Example epichlorhydrin and aqueous caustic soda solution were added to molten 2,2-bis (4-hydroxyphenyl)-nonadecane, the mixture refluxed, cooled, neutralised with hydrochloric acid and washed with water. Volatiles were removed by vacuum distillation to give a viscous amber liquid as product. In a further example triethylenetetramine was added to the epoxy resin and the mixture of resin and curing agent applied to steel strips which were overlapped by one-half inch and cured by heating. The strips were cooled in liquid nitrogen to -190 DEG C. and the shear strength of the cured resin tested and compared with the resins prepared from the bis-phenols derived by condensing 2 moles of phenol with 1 mole of acetone, methyl amyl ketone, methyl heptyl ketone, methyl nonyl ketone or dinonyl ketone.

Title: Improvements in tip buckets
IPC: B65D88/56
Filed: 1919-12-10
Abstract: 154,799. Foy, J., and McVey, J. Dec. 10, 1919. Tip-buckets are fitted with latching-mechanism which is connected by a supplementary chain to the hoisting-chain and is operated automatically to dump the load when the hoisting-chain is slackened first and then raised again. The apparatus comprises a pair of parallel bent levers C pivoted to the 'bail at C<1> and engaging a fixed fork D on the bucket. The tail ends of the levers carry a shaft on which is fixed a ratchet-wheel 4 and a double link 3 attached by the chain 7 to the hoisting-chain. The apparatus is set by adjusting the length of the chain 7 until the pull on the hoisting-chain will not swing the levers bodily about the pivot C<1>. This end is attained when the link 3 is upwardly inclined as illustrated, and abutting against a stop 8. When the appliance is set, the pawl 5 is moved by hand into engagement with the ratchet-wheel. When the bucket rests on the ground, or elsewhere, and the hoisting- chain is slackened, the link 3 falls by gravity until it abuts against the lowest stop 9. During this operation, the ratchet-wheel overruns the pawl so that, on re-hoisting, the link 3 is fixed in alinement with the tail of the lever, which shortens the effective length of the chain 7 so that the lever C is swung about its pivot to release the fork D.

Patent GB-409751-A (GB)
Title: Improvements in organ-like instruments for the electrical production of sound
IPC: G10H3/08
Filed: 1932-11-05
Abstract: 409,751. Electrical musical instruments. ROBB, F. M., 217, East Bridge Street, Belleville, Ontario, Canada. Nov. 5, 1932, No. 31290. Convention date, Nov. 5, 1931. [Class 88 (ii).] An electrical musical instrument, in which the sounds are produced by phonic wheels rotated in front of electromagnets the alternating currents generated being amplified and conducted to loud-speakers or the like, is arranged with the phonic wheels 35, Fig. 11, mounted on twelve shafts 34 successively at speeds increasing in the ratio 12 : 2 to represent the twelve notes of an octave. Each shaft carries a set of wheels for each timbre to be produced, the (say, five) wheels of each set sounding respectively a note of given timbre and the (four) octaves thereof. A single amplifier, or an amplifier corresponding to each stop or each shaft, may be used. The shafts may be rotated by a single belt passing round pulleys of different sizes (Fig. 12, not shown) ; or worm or spiral gears may be used ; or each shaft, may be individually driven and synchronised with an automatically vibrated tuning fork. A number of diagrams of series and parallel wirings for the key and stop contacts are given, the contacts in some cases being opened, and in others closed, for operation. For instance in Fig. 4, three stops are wired in parallel and four keys in series, the stop contacts S closing to sound, and the key contacts K opening to sound. An electromagnet 37, Fig. 13, may be adjusted on its pivoted base 39 towards and away from its phonic wheel 35 by a nut 38 acting against a spring 40. The wave forms may be cut laterally on the discs 35. It is desirable to make the wave forms of the higher octaves of rather greater amplitude in proportion of their length, than the amplitude of the lower notes. Volume is controlled by a swell pedal operating a variable resistance in the output of the amplifiers or in the loud-speaker fields. The Specification as open to inspection under Sect. 91 comprises also : (a) a number of phonic wheels on one shaft, the first wheel representing the fundamental and the others harmonics of a single note ; (b) a single phonic wheel with a number of electromagnets connected with resistances, disposed around it. This subjectmatter does not appear in the Specification as accepted.

Title: Improved cutter guard for joiners and like machines
IPC: B27G21/00
Filed: 1948-12-03
Abstract: 654,613. Machinery guards. PEAT, J. T. Dec. 3, 1948, No. 31355. [Class 80(iv)] A guard for the rotating cutter 6 of a joiner or like wood-working machine comprises a shield plate 9 arched over the cutter 6 with its longitudinal edges resting on the machine worktable 4 and pivoted from a lever block 11 fulcrumed on a pin 12 at the rear of the worktable by two parallel links. 10 disposed substantially beneath the worktable surface. A tension spring 15 acting through an arm 14 partially counteracts the weight of the shield plate and links, and a tension spring 16 disposed between the links 10 leads the shield plate towards an adjustable work guide fence 7. The arrangement is such that an upwardly and forwardly inclined deflector horn 20 either causes the shield plate 9 to lift when a flat piece of material 21 is fed into the machine, after which the weight of the shield plate 9 returns the latter to the worktable, or alternatively causes the shield plate to move across the worktable if a piece of material is fed edgewise into the machine, after which the spring 16 returns the shield plate towards the guide fence 7, movement being limited by a stop screw 18. A further horn 24 may be provided to ease the return of the shield plate 9 to the rest position, and both horns may be replaced by a handle (not shown), for manual lifting of the shield plate. Manual pressure on the latter in a downwardly direction or towards the guide fence 7 prevents bucking of the material passing through the machine.

Title: Improvements in apparatus for handling material
IPC: E21F13/02
Filed: 1925-12-14
Abstract: 245,094. Stockly, W. D. Dec. 14, 1925. Portable endless - chain conveyers with parallel chains; feeding-devices; driving- gear; directing and adjustably supporting. - A portable inclined conveyer for loading coal from a heap comprises a series of digging or agitating elements 39 and of driving members throughout the length of the head shaft 11 at the lower end, and a flexible conveyer member providing a supporting surface effective substantially throughout its length and width and engaging the driving members on the tail-shaft for operating the digging members 39. The digging members are advanced into and under the heap and actuated to destrov the equilibrium of the material so that it descends on to the conveyer belt and is removed. By this method of operation the agitator operates only upon a small proportion of the material to be removed and the efficiency of the loader is increased. The machine comprises side frames 10 carried on wheels 29, 29<a> and projecting above the conveyer so as to form retaining walls for the material. The wheels 29<a> form part of a steering unit 33 - - 36. The wheels 29 are driven by ratchet gearing 30, 31 operated by the driving- gear of the conveyer so that the machine is advanced as material is removed from the heap. The tail shaft 12 of the conveyer is driven from a motor 20 through a countershaft 16, and drives a sleeve on the countershaft carrying an eccentric or cam which actuates the ratchet gearing 30, 31 through a rod 25. The machine may also be moved forwards by a push-bar 32. The conveyer comprises a set of parallel endless chains formed of closed oval links 37, Fig. 4, or disconnectible flat links 45, Figs. 5 and 6. The sprockets for these chains are keyed upon the tail shaft 12 or formed in a single member keyed on the shaft. One arrangement of the head shaft 11 for digging into and agitating the material is shown in Fig. 3. Discs, such as that shown in Fig. 4<a>, with teeth projecting beyond the chains, are arranged between adjacent sprockets, the head shaft 11 being keyed to and driven by one or more of the sprockets. In the arrangement shown in Figs. 5 and 6, the sprockets themselves are provided with digging teeth 47 and the separate discs are not used. An apron plate 43 is arranged beneath the conveyer chains, and is slotted at both ends so that they may approach closely to the sprockets. In a modification, Figs. 9, 10 and 12. the apron plate 43 carries a nosepiece 50 having a set of bearings 51 for the head shaft. The shaft carries combined sprockets and agitators 53 between the bearings 51. The conveyer element is formed of V-shaped links 55 carried by pins 56, and is driven by a sprocket wheel engaging the lower run. This form of machine is supported on an endless track instead of upon running wheels.
