Title: Improved apparatus for baking or drying substances at high temperatures and for subsequently cooling same
IPC: A21B1/42
Filed: 1921-05-03
Abstract: 185,460. Greenwood, R., and Carr & Co., Ltd. May 3, 1921. Cooling-chambers.-In an apparatus for baking biscuits &c. and for drying materials at high temperatures, the goods are caused to ascend through a vertical oven having a number of independently-controllable heating-zones, and then to descend through an adjacent chamber to which air for cooling is admitted at the lower end. The goods are carried on trays 14, and in each chamber these are raised or lowered by a pair of endless conveyers 8, 10 having angle-iron supports 13 for the trays. Near the upper end of the heating-chamber 1 the trays are transferred to the cooling-chamber 2 by an endless chain 21 having abutments 22, which push the trays from the supports of the heating-chamber conveyers on to aligned supports of the conveyers in the cooling- chamber. The driving-mechanism for the conveyers of the cooling-chamber is preferably geared down relatively to that of the heating- chamber conveyers, and the supports for the trays are set closer to correspond with the reduced rate of travel. The cooling-air is withdrawn from the chamber 2 at a level beneath that of the point of transfer between the two chambers, so that a more or less dead air space is formed at the top of the cooling-chamber.

Title: Improvements in and relating to the manufacture of cyanine dyes and their use in photography
IPC: C09B23/04
Filed: 1933-05-02
Abstract: Gelatino silver halide emulsions are sensitized to the blue and violet regions of the spectrum by means of oxacyanines.  These dyestuffs are prepared by condensation of two molecules of a quaternary salt of a benzoxazole or naphthoxazole containing a m -methyl group by means of an ester or salt of nitrous acid and an anhydride of a lower aliphatic acid.  In examples: (1) 2:2<1>-dimethyl oxacyanine iodide is prepared from 1-methyl-benzoxazole methiodide in the presence of boiling acetic anhydride and amyl or butyl nitrite; (2) 2 : 2<1>-diethyl oxacyanine iodide is prepared from 1-methylbenzoxazole ethiodide using acetic anhydride or propionic anhydride and amyl or butyl nitrite; (3) 2 : 2<1>-dimethyl and 2 : 2<1>-diethyl-5 : 6 : 5<1>-6<1>-dibenzoxacyanin iodide and 2 : 2<1>-dimethyl and 2 : 2<1>-diethyl-3 : 4 : 3<1> : 4<1>-dibenzoxacyanine iodide are similarly prepared from the corresponding quaternary salts of a  and b -naphthoxazoles.  The wavelengths at which maximum sensitivity is shown for the above named cyanines are tabulated.  For the preparation of the emulsions methyl alcoholic solutions of the dyestuffs diluted with water may be added to the gelatino silver halide emulsion before it is applied to a glass or cellulosic support.  Alternatively the coated film or plate may be bathed with a solution of the sensitizer.  1-Methyl-a -naphthoxazole and 2 - methylb  - - naphthoxazole, may be prepared by the standard method from the o-aminonaphthol and acetic anhydride. Substituted 1-methyl benzoxazoles may be prepared by the same method from the o-aminophenols. Methoxy-methylbenzoxazole is mentioned.

Patent GB-132596-A (GB)
IPC: B60C23/12
Abstract: 132,596. Cumming, W. G. Sept. 14, 1918. Actuating pumps by motion of vehicles.- Single-acting air-pumps, actuated by the depression of the tread of the pneumatic tyre as the tyre passes over the ground are provided with spring-actuated means whereby the pump plunger is held normally in contact with the end of the cylinder. Two forms are shown, that in Fig. 1 being mainly external to the tyre, while that in Fig. 4 is mainly contained within the tyre. On a depression of the tyre taking place, the hollow rod 4, Fig. 1, raises the outer end of the lever 14 and, by the inner end of the lever, depresses, against the action of the spring 22, the pump plunger 16, with the consequent introduction of fresh air through the valve 15 and filter 15<a>. On the tyre regaining its shape, the air is transferred through the valve 17 to the pump cylinder, and thence by the rod 4 to the tyre. On an extended thrust of the rod taking place due to a blow or violent jar, the lever 14 is wholly raised and the rod allowed to pass onwards. On the return of the rod, the lever follows it up, owing to the reaction of the spring 22. The presence of the spring also ensures contact of the plunger with the end of its cylinder. In the form shown in Fig. 4, the pump plunger 31 is retained normally against the end of its cylinder by reason of its connexion with the spring 47, the outer ends of which are secured to the respective ends of the toggle mechanism 29, 27. On a depression of the tyre taking place, the togglearms are thrust apart, and air is drawn through the body 37, tube 49, and valved plunger 31 into the end of the cylinder. When the tyre resumes its normal outline, the parts return to their original position, and the air in the cylinder is driven through the valve 43.

Abstract: 904,724. Tension indicators. GENERAL ELECTRIC CO. Ltd., and RICHES, W. April 12, 1961 [April 13, 1960], No. 13284/60. Class 106 (2). In a tension-measuring device, to be interposed in a rope or the like, in which deformation of a spring actuates an indicator means, means are provided to increase the resistance of the spring to deformation when the tension reaches a specified amount, higher tensions being then indicated on a reduced scale. As shown in Fig. 1, two U-shaped springs 16, 17 are linked by shafts 10, 11 which are drawn apart by rope tension applied to shackles 1, 2, thereby displacing racks 52, 53 to rotate pinion 51 and a calibrated drum 3 co-operating with a fixed pointer 5. When the tension reaches a predetermined value, the arms of the U-shaped springs will bear against rods 43, 58 and the springs will effectively stiffen. The rods 43, 58 are carried by bolts 36, 48 at either end, these bolts being, in turn, adjustably fixed to rods 35, 39 extending between two pairs of overlapping triangular plates 18, 19, fixed at their apex to bolts 10, 11. The base end of each plate has a slot for the free movement of the other bolt. Movement apart of the bolts 10, 11 thus increases overlap of the plates and draws the rods 43, 58 towards the arms of the U-shaped springs. At the predetermined tension, the scale on drum 3 changes to show greater tension increments per division. Should the springs fracture under too great a tension, movement apart of shafts 10 and 11 will be constrained by the plates 18, 19.
