Patent GB-257691-A (GB)
Abstract: 257,691. Wilkins, S. D., Reiner, H. C., and Gould, E. C. June 15, 1925. Sugar preparations.-In a process for producing a dried molasses product from liquid molasses by first heating it at a non-injurious temperature to lower its viscosity, and next passing is through a dehydrating apparatus to evaporate it to dryness, a minor proportion of a moisture-proofing stabilizer, preferably skimmed milk solids, casein, blood, egg albumen, or other products of a colloidal nature, for example those from seaweed, is incorporated with the molasses at the first heating. The lowering of the viscosity is preferably effected bv treatment at about 190‹ F. with live steam. The final dehydration may be continued until a relatively fine powder containing less than one per cent of moisture is obtained. The produce is non-hygroscopic and is applicable to substantially all uses of the liquid molasses. In an example one part of casein or skimmed milk solids is mixed with two parts of liquid blackstrap molasses; the finished product may be used as a basis for animal fodder.

Abstract: 950,855 Lamp failure warning devices; road traffic signals on vehicles. FLEXIBLE LAMPS Ltd., G. L. FLEWITT, and L. C. BAKER. July 26,1960 [July 27, 1959; Dec. 29,1959], Nos 25770/59 and 44107/59. Headings G4N and G4Q. In an arrangement in which failure of a lamp on a road vehicle causes the relapse of a normallyoperated relay thus extinguishing a normallylighted monitor lamp, provision is made to compensate for the change in load when one or more additional lamps, mounted on a trailer, are connected into or removed from the circuit. Operation with vehicle lamps only. Actuation of switch 14 connects up lamps 10A, 11A or 10B, 11B in series with flasher unit 17 and relay 19 whereupon relay 19 operates in time with the lamps concerned and flashes monitor lamp 20 in synchronism therewith. Failure of a lamp reduces the current in relay 19 by 50% whereupon the relay no longer operates and lamp 20 remains unlit. Operation with trailer lamps. Connection of the trailer lamp 13A or 13B into circuit effects via the plug 12 the connection of ground to the lower counter-wound winding of relay 19 the resistance of which is such that it produces flux corresponding to that produced by the load current of one lamp. The total effective flux in relay 19 therefore remains the same as it was with the vehicle lamps only in circuit, and lamp failure produces the same result as before.

Title: Improvements in or relating to the production of synthetic resins from polysaccharides
IPC: C08B37/00
Filed: 1962-07-05
Abstract: In a process for making hardenable resins from cellulose or other vegetable polysaccharides or from materials containing such polysaccharides, the polysaccharides or materials containing them are heated under acidic conditions with an alcohol containing less than 10% by weight of water, and the resin separated from the resulting solution of resin in alcohol.  The polysaccharide material may be e.g. wood, grain husks, straw paper, potato tops, hay, dried weeds or pine needles.  The acid is prefably a hydrogen halide, in a concentration of 0.01-10% by weight of the reaction mixture and the alcohols, which do not undergo any reactions in the process, are preferably saturated alcohols having at least three carbon atoms. The heating temperature is preferably 200-300 DEG C.  The resin may be separated from the reaction mixture by steam distillation, and may be hardened with curing agents e.g. hexamethylene tetramine.  In examples conifer waste and newsprint are heated, in presence of hydrochloric acid, with n-butanol, cyclohexanol and amyl alcohol.

Abstract: 467,061. Step by - step conveyers. HAYTHORNTHWAITE, J. Sept. 29, 1936, No. 26404. [Class 78 (i)] [Also in Group XVIII] Articles or boxes of substantially cubical shape are moved in a closed path consisting of two columns of boxes &c., the top box of one column being transferred to the top of the other column, the bottom box of which is simultaneously moved to the bottom of the first column, the lifting and lowering and the traversing mechanisms being so interconnected that their respective movements balance one another. Fig. 1 shows transferring, lifting and lowering mechanism comprising parallel swing- ing arms 32 pivoted at 33 to, a fixed cross-bar on the frame 1 and carrying at the top and bottom lateral transferring means 31 and 42. Oscillation is imparted to the arms 32 by a link 43 pivoted to a rocker 7 hinged at 8 and operated by a rod 10 connecting it to a crosshead 12 reciprocated vertically on guide rods 13 by a rod 14 coupled to a crank 15 rotated by a chain or like driven wheel 16. From the rocker 7 depend two rods 5, 44 pivoted to plates 17, 45 respectively, whereby the column of boxes 4 is raised and the column 3 is lowered. The plate 17 rides on guides 20 and carries two spring-pressed hinged Jugs 21 having an incline on their lower sides which enables them to turn aside and snap under ledges 22 overhanging the top edges of each box. Similar lugs 23 on the frame 1 are turned aside by the rising ledge 22 and snap beneath same to hold up the column of raised boxes when the plate 17 begins to descend. The plate 45 rides on guides 46 and has a counterbalanced hinged shelf which takes under the ledge 22 and is prevented from turning down by a pawl 50 bearing against an extension of the shelf. A projection 54 on the pawl 50 hits a trip 53 to turn aside the pawl and let the shelf slip vertically past the ledge as the plate 45 ascends, the counterweight then bringing the shelf to horizontal and the pawl 50 falling back to retain it so. A spring-pressed pawl 61 holds the column 3 up while the plate 45 is rising and is tripped to release same by a striker 59 on the plate 45 lifting an obstructing lever 58. The upper lateral transfer device 31 comprises pivoted pawls 29, Fig. 4, which are pressed out from the plate 31 to engage under a box ledge 22 by a projection 40 thereon moving over an outwardly curved abutment 41. A pin 34 on the back of the pawl bears against a pivoted rod 35 to retain the pawl in position till the plate 31 is swung over the column 3, when the rod 35 strikes and is raised by a stop 38 to free the pin 34 and allow it to enter a hole 37 and let the pawl fall. The lower lateral transfer device consists of a cradle 42 which receives the bottom box of the column 3 when released, and holds it below the column 4 till it is removed by the rising plate 17.

Abstract: 1,096,302. Return tube steam and hot-water boilers. MARSHALL SONS & CO. Ltd. Oct. 2, 1964. [July 4, 1963], No. 26496/63. Heading F4A. In a shell and tube type boiler for generating steam or heating water, the water space 4 is defined by a tubular metal shell 1 with front and rear tube-plates 2 and 3 extending across the bore of the shell at each end. A smaller tube plate 5, conveniently being between one-half and two-thirds of the diameter of the tubeplates 2 and 3, is joined to the rear tube plate 3 by a metal ring 6 to form a combustion chamber 12. A wide bore burner tube 10 which opens into the combustion chamber 12 extends through the water space 4 to the front tube-plate 2 at which end is situated a burner 11. A first group of tubes 7 connected to the combustion chamber 12 extend through the water space to the front tube-plate 2 and open into a front gas-reversal chamber 15 formed by part of a hinged and davited front door 8, provided with refractory lining 8a, and a partition 16 attached to the door 8. A second group of tubes 7 connected to the front gas-reversal chamber 15 extend through the water space to the rear tube-plate 3 and open into a rear gas-reversal chamber 18 formed by a hinged and davited rear door 9, provided with refractory lining 9a, which supports a refractory member 13 separating the combustion chamber from the gas-reversal chamber 18. A third group of tubes 7 connected to the rear gas-reversal chamber 18 extend through the water space to the front tube-plate 2 and open into a flue chamber 20 formed by part of the front door 8 and separated from the front gas-reversal chamber by the partition 16. The total cross-sectional area available to the combustion gases that flow through the groups of tubes is reduced successively at each tube group. The tubes of the various group may be plain, gilled or convoluted and the burner tube 10 may be corrugated. In a modification, a fourth and even a fifth group of tubes may be added to increase the number of passes made by the combustion gases, gas-reversal chambers and the flue chamber being arranged at the appropriate ends to allow continuous flow. In the embodiment shown, the front door 8 is formed with a suitable aperture in which the burner 11 is disposed to project into the burner tube 10 but, in a further modification, a second separate front door, disposed on the outside of the door 8, may be employed to support the burner 11.

Abstract: 1,237,372. Engine test beds. JOHN CURRAN Ltd. Aug. 5, 1968 [June 9, 1967] No. 26626/67. Heading G1W. A bed supporting a gas turbine jet engine Fig. 9 under test comprises stationary and movable supports 25, 29 and connections 31, 32 acting there between comprising flexible link elements 10a, 10b, Fig.3 (not shown) arranged so that, at least under certain test conditions, one link 10a is in tension and the other 10b in compression, the latter being provided with a relatively stiff length 14 located between two relatively flexible lengths to confine the region of flexing. Both links may be stiffened, Fig. 4, they may be staggered and the common part 13 may be on the stationary or movable part. Each support connection may comprise two thin metallic straps 54, 55 Fig. 10, with their opposite ends clamped between spacer blocks 56, 57 by bolts 58 securing them to lugs 51, 52 and a frame 50 to which the engine carrier 40 is secured. The central parts of the straps 54, 55 are clamped between pairs of rigid plates 59, which are apertured to receive a sleeve 60. The ends of the sleeve 60 are connected to spigots engaged in apertures in bearing plates 61, 62 (relative to which the sleeve can be adjusted) and the plates 61, 62 are carried by a stationary base 66 frame through trunnions 64, 65. Engine thrust is measured by a load cell 68 positioned between a member 67 (secured to the frame 50 through the spacers 56, 57 and lugs 51, 52) and an anvil 69 carried by a rigid yoke 70 attached to the base 66. The lengths of each strap 54, 55 between the central spacers 59 and outer spacers 56, 57 are surrounded by stiffening plates 72, 73 connected thereto non-positively by bolts 75 arranged to connect the plates 72, 73 at points beyond the edges of the straps, the grip being insufficient to transmit tensile or compressive loading from the straps to the plates. Protective end covers may also serve as stops to limit movement should a strap break. The strap may be of 16 gauge steel sheet approximately 0À064 inches thick and of total length 30 inches, and the unit may accomodate a deflection under thrust of up to 0À02 inches or even 0À1 inches. Vertical and transverse thrusts can also be measured in apparatus with further supports mounted one on another by similar strap units for limited relative movements in the required directions. Other methods of stiffening flexible elements are envisaged and rigid links if flexibility is provided at the ends e.g. with coiled springs, leaf springs or elastomeric brushes arranged to distort angularly in shear.
