Abstract: 313,235. Dreyfus, H. March 24, 1928. Alkory aliphatic anhydrides.-Alkoxy aliphatic anhydrides or their substitution products are prepared by bringing metallic salts of the corrrespondacids into reaction with sulphur di- or tri-oxide and chlorine, or with compounds of sulphur di- or tri-oxide with chlorine. Suitable compounds are sulphuryl chloride and chlorsulphonic acid and its salts. and such compounds may be employed together with chlorine and or sulphur di- or trioxide. Preferably, the anhydrous pulverulent alkali-metal salts of the alkoxy aliphatic acids are employed and the reaction is conducted in an inert meduim, advantageously in the anhydride to be produced; the process may then be conducted continuously. The anhydrides may be freed from traces of sulphur or its compounds by treatment with suitable metals or metal compounds, such as lead oxide or copper oxide, or by treatment with chlorine and a metal salt of the acid coresponding to the anhydride. In one example, dry powdered sodium methoxyacetate mixed with methoxyacetic anhydride is treated with a solution of sulphuryl chloride in methoxyacetic anhydride at a temperature below 15‹ C.; the product is distilled in vacuo when the reaction is complete. In another example, sulphur dioxide and chlorine are used. Reference is made also to the preparation of anhydrides from the ethyl and propyl ethers of glycollic acid and the methyl, ethyl, and propyl ethers of lactic and hydracrylic acids. Specifications 313,233 and 313,284 are referred to.

[Class 98 (i)] A focal plane shutter, of the type in which tapes on a leading curtain are wound on coaxial spools 20 and the following curtain is wound on a drum 17 between the spools, includes a pivoted lever 52 movable with the shutter speed dial 56 and having parts 63, 64 respectively coaxial with, and extending radially of, the dial, together with a pin or projection 50 which moves in an arcuate path with one of the spools 20 and during the unwinding of the leading curtain moves the lever 52, so causing the coaxial portion 63 to actuate means for releasing the follower curtain. As shown, the lever 52 is pivoted on a bracket 54 secured to the shaft 55 of the speed dial. The pin 50 extends from the face of the upper spool 20 through an arcuate slot in the mechanism plate, and engages the end 64 of the lever 52 to release the following blind at a moment determined by the position of the lever, as set by the speed dial, so determining the width of the slit formed between the blinds in the usual manner. The release of the following blind is effected by the part 63 of the lever 52 rocking a lever 70, so disengaging a lug 74 carried by it from a pin 75 on the drum 17. The shutter is set and the film wound by moving a handle 11 through a full stroke, which through a one-way spring clutch 28 and gears rotates the shaft carrying the film sprockets 25. Motion is transmitted from this shaft by means of pulleys and spring belts 34, 38 to the film take-up spool 10 and to a disc 40 to which is secured an annular spring 41 carrying a pin 43 which engages a pin 44 on the lower spool 20, thus rotating the spools. The drum 17, which is loose on the spool shaft, is rotated from the lower spool 20 through a pin and slot lost motion connection 118, 119, which allows the necessary relative movements between the blinds during the exposures. During the winding of the shutter, a disc 48 on the release rod 46 engages a lug 77 on the lever 70 which is thus held so that the lug 74 is disengaged from the pin 75. When the release is depressed the lever is freed so that the lug engages the pin 75 to retain the following curtain, and subsequently a second disc 49 on the rod engages a lug 42 on the spring 41 and depresses it so that the pin 44 is freed from the pin 43 and the leading blind is released. The shutter is adjusted for " bulb exposures by rotating the lever 52 to a point at which it is not engaged by the pin 50, so that the following blind is released only when pressure is removed from the shutter release knob.

Abstract: 568,608. Altering physical structure by stretching. FORSSELL, C. A. June 8, 1943, No. 9218. [Class 83 (iv)] In improving a constructional steel element by cold stretching, projecting anchoring means are provided at the ends or at one end of the element and are used to attach the element to the stretching machine. The anchoring means may comprise plates 12, 14 welded, riveted or wedged to one or both ends of the element, and these plates may engage the clamping jaws of an ordinary stretching machine, but preferably they are engaged behind rigid jaws 13, 16 of a movable slide 4 and a fixed part 1 of the machine shown. The plate 14 engages the jaws 16 through a slide 15, Fig. 7, having slots 24 to receive the elements or bars 11, two being stretched at one time. The bars 11 are introduced into the machine by moving the slide 15 along a horizontal guide 19 and the rest of the bars into the intermediate jaws 18, while the plates 12 and adjacent end of the bars 11 pass along a guide 20 and behind the jaws 13. If desired, an intermediate guide plate 17 may be used to keep the bar 11 straight. If heavy and stiff bars &c. are to be stretched, the machine may be arranged with slots between the jaws vertical, the work being introduced by a crane. The element to be stretched may have two or more spaced means 14 at the end of such a size that they will pass through the jaws 16, one of these means 14 being engaged by a slide 15. The slide 4 is moved to stretch the bars 11 by an electric motor 10, worm gearing 8 and nuts 6, .or hydraulically. The anchoring means may be removed with or without the unstretched part of the element or they may remain for use in concrete or for attaching to another element. In this case, the tensile force may be applied in stretching in the same way as it would act on the anchoring means in use.
