Title: New 5-nitrofuran derivatives
IPC: A61K31/44
Filed: 1962-02-16
Abstract: The invention comprises 5-nitrofuran derivatives of the general formula:- <FORM:0925569/IV(a)/1> in which R is a hydrogen atom or alkyl radical; the quaternary ammonium salts and N-oxides thereof. The compounds are prepared by heating 5-nitrofurfurol with an alkyl pyridine at 50-200 DEG C. in an acid medium, e.g. acetic anhydride. The quaternary ammonium salts may be obtained by further reaction with alkyl or aryl halides.  The N-oxides are obtained by oxidising the pyridine derivative with a per acid, e.g. perbenzoic or peracetic acid.

Title: Improvements in or relating to concrete mixing machines
IPC: B28C7/08
Filed: 1929-02-26
Abstract: 329,713. M³cke, E., and Rajtora, V. Feb. 26, 1929. Feeding-devices.-The charging skip of a concrete-mixing machine is raised and lowered by crank mechanism the crank pin being connected either directly or indirectly to the skip by ropes or levers. In the form shown in Fig. 1 the drum 1 is rotated by a shaft 2 which drives a counter shaft 8 through worm gearing 6 and clutch 27, the countershaft having mounted thereon a crank disc 9 provided with a number of holes 24, 24<1> for the reception of a pin 10. The pin is connected to a lifting rope 11 by an eyepiece having a number of holes 38<1>, 38<11>; by adjusting the pin 10 in the holes 24, 24' the lift may be varied, while by varying the particular hole 38', 38" engaged by the pin, the upper limiting position of the skip may be maintained constant. The crank disc 9 is provided with one or more recesses 23 in which engages a projection on a threearmed, spring-returned hand-lever 19 controlling the clutch. In the position shown the clutch is disengaged and the skip in its lower position. Operation of the lever 19, either manually or automatically, engages the. clutch and starts the hoisting operation which is continued till the crank pin has rotated half a revolution. The skip is then lowered and the clutch thrown out of gear by the entry of the projection 22 into the recess 23. A second recess may be provided to stop the mechanism with the skip in its upper position. In another form the hoisting rope passes over a pulley mounted on the crank pin. The rope may also be connected to a pivoted arm which is rocked by the crank pin engaging a slot therein; the slot may be curved so as to effect a dwelling period with the skip elevated. The rope may be connected to the arm at variable distances from its end to vary the lift; in this form the end of the arm is curved at the connecting point, so that the upper position of the skip is constant. In a form illustrated diagrammatically in Fig. 5 the arm 35<1> is pivoted to a second arm A which can be moved about its pivot by screw mechanism 36; by these means the throw of the arm 35<1> is varied without varying the top position of the skip.

Abstract: 704,165. Hot-water supply systems. RANGE BOILERS, Ltd. March 17, 1952 [March 17, 1951], No. 6454/51. Class.64(1) In a domestic hot water supply system comprising a closed hot water reservoir a and an adjacent open cold water reservoir b connected together by an inlet pipe f leading to the bottom of the hot water reservoir from the cold water reservoir, to which cold water is supplied through a float-controlled valve, means are provided at the upper end of the inlet pipe f to reduce convection circulation therefrom into the cold water reservoir a. In the forms shown, an air lock is formed by an inverted cup h located above and partly overlapping a shallow cup e around the top of the pipe f. The cup e and/or the pipe f may be of non-conducting material or jacketed with solid or air insulation. In one form, Fig. 2, the expansion pipe g extends through the pipe f and the cup h. 'The cup e may have upward projections to support the cup h. In another form, Fig. 8, the expansion pipe is in two parts, g<SP>1</SP>, g<SP>2</SP>. The lower part g<SP>1</SP> may be omitted, a hole being provided in the side of the pipe f near the top. The cups e, h may be replaced by an inverted cup, from which air has been allowed to escape, or other baffle arrangement. Specification 453,294 is referred to.

Filed: 1927-03-08
Abstract: 284,488. Tasman, G. March 8, 1927. Bodies.-Relates to joints between wooden rails and pillars, used in the construction of automobile bodies, &c. According to the invention, a wooden key 13, the grain of which runs in the same direction as that of the pillar 16, is glued into a groove in the end of the rail 11, a transverse aperture 15 is formed through the rail, and holes 14, 17, of the same diameter, are bored through the pillar and rail, the hole 14 passing from the centre of the end face of the rail into the aperture 15. The end of the rail and the key 13 are then glued to the pillar, with the holes 14, 17 in alignment, a lining tube 18 is inserted through these holes, and a bolt 19 is passed through the tube, a nut being screwed on the end of the bolt in the aperture 15. Grooved dowel pins 21 are finally glued in holes bored obliquely through the rail 11, key 13, and pillar 16. The end of the key may be recessed into the pillar. Two rails 29, 30 may be joined to one pillar 31, Fig. 4, in the manner described above, but with a single connecting-bolt 19. Instead of one key, several keys may be provided in grooves in the end of a rail. Where the rails and pillars are very narrow, so that the aperture 15 cannot be made large enough to allow a wrench to enter for tightening the nut, the outer end of the bolt is so formed that the bolt may be turned by a screwdriver or wrench.

Title: Improvements in elastic fabric and in the production thereof on braiding-machines
IPC: D04C1/00
Filed: 1937-03-09
Abstract: 491,854. Elastic braid. PRICE, W. H. March 9, 1937, No. 6953. [Class 74 (i)] Relates to the use of elastic threads to help in forming scalloped edges or other effects in lace &c. made on braiding-machines. Fig. 1 shows a piece of the finished braid with scallops c. Fig. 2 shows a small piece of the same braid in process of making. The elastic threads b and non-elastic threads a are both drawn from traversing bobbins. The threads a traverse some in one direction and some in the other direction, to form the substance of the scallops c. The elastic threads b, preferably wrapped with cotton &c., are traversed under tension from the extreme edge of the material to a suitable distance in the width of the fabric and back again. When the tension is released the scallops are forced out as shown in Fig. 1. Other elastic threads y combine with the body threads to produce longitudinal elastic pillars. These threads may be drawn from running bobbins or passed up through the centre plates. There may be two sets of traversing scallop-forming elastic threads. When the finished braid is to be sewn on to a knitted fabric or run on the needles of a knitting-machine the other, unscalloped edge j is made from comparatively fine threads.
