Abstract: 103,536. Musker, A. Feb. 4, 1916. Trimming and spreading apparatus. -Coal or other material is trimmed or distributed in bunkers or other chambers by reciprocating devices arranged at or near the top of the bunker or chamber. In Fig. 1, an arrangement is shown for a ship, in which coal supplied through a hatch to the top bunker 4 passes through hatches 15 to the lower bunkers 5, 6, and is moved by the distributing- devices 22 to the forward bunker 7, from whence it falls through the batches 16 to the bunkers 8, 9. The distributing-devices 22 are carried by bars 20 and frames 21, which are reciprocated by mechanism 26. In the bunkers 4, 7, 5, the distributing-devices 22 are all pivotally mounted on the frames 21, and are kept in position to move the coal by the engagement of arms 25 with stops 24 when the bars are moved to the right. The distributors in the bunkers 8, 9 are fixed blocks, and the distributor in the lowest bunker 6 is a fixed plate. Similar devices may be arranged to move the coal towards the stokehold doors. Instead of the apparatus being fixed permanently to the ship or other structure, it may be portable and attached temporarily to the vessel &c. In an arrangement for supplying the sets of bunkers 4, 5, 6 and 7, 8, 9 through separate hatches (not shown), some of the distributing-devices are shaped angularly, some elliptically, and others are flat plates. The distributing- device 22, Fig. 6, fits closely to the underside of the deck and works in a casing 22<x>. When the block 22 is out of its casing, is closes the hatch 15 either wholly or partly. In the construction shown in Fig. 9, the distributing-devices 22 are pivoted in arms 31 which are pivotally mounted in the deck &c. In each construction, the distributors are connected tc the bars or frames in such a manner that they can be readily changed to allow an appropriately-shaped distributor to be used for any particular material operated on. According to the Provisional Specification, the apparatus may be arranged to collect coal into a heap, and for this purpose one or both ends, or intermediate portions, or both, may be arranged in adjustable supports, and the plates &c. 22 may be carried on endless bands and moved continuously.

Abstract: 1,157,394. Making pressure vessels; assembling force fits; jointing. BAROGENICS Inc. 12 Jan., 1968 [22 May, 1967], No. 1916/68. Headings B3A, B3U and B3V. [Also in Divisions B1 and G6] A pressure vessel is made by expanding a hollow, segmented, support cylinder 10, inserting a sleeve 14 into the cylinder and allowing the support to contract to produce hoop compression in the sleeve. The sleeve is then machined to make its ends flush with the support and end caps are welded to the ends. The support cylinder is composed of segments 18a &c., each with two pairs of holes 22 through which pins 24 are inserted. The pins preferably extend the whole length of the cylinder but shorter pins may be used. The pin ends are threaded and nuts serve to clamp the segments together. The support cylinder is expanded either by the sleeve 14 or by an intermediate sleeve 30. In the former case the bore of the support cylinder is tapered as is the outer surface 27 of the sleeve. The sleeve is forced into the bore by an hydraulic press or jack. This method is particularly suitable for small pressure vessels. In the latter case the intermediate sleeve 30 is expanded by a wedge 36 forced into a slot in the sleeve to expand the support cylinder. Alternatively several wedges (54), (55), (56) may be used in spaced slots in the sleeve, Fig. 4 (not shown), or two wedges (42), (44) co-operating together in one slot, Fig. 3 (not shown).

Abstract: 821,356. Optical range-finders. ZEISSSTIFTUNG, C., [trading as ZEISS, C.. [Firm of]]. Jan. 23, 1957 [Jan. 28, 1956], No. 2374/57. Class 97(1) [Also in Group XL(b)]  In a range-finding system light from a lamp is modulated in intensity and focused by a lens on a reflector located at the distance to be measured and the light returned by this reflector and by another reflector disposed within the crosssectional area of the modulated beam is focused by the lens into two images, the brightness of which may be adjusted to equality by axial displacement of at least one reflector. Alternatively, a single reflector is provided and part of the light is returned thereby to a photo-cell which also receives another part of the light returned by said reflector after said part has passed again through the modulator, a flicker diaphragm being disposed in the light path to the photo-cell so that the part beams are incident thereon alternately. In the form shown, light from lamp 1 is polarized at 10 and passes through quartz plate 9 and polarizer 11 and is focused by lenses 3, 4<SP>1</SP> and 3, 5<SP>1</SP> on mirrors 4, 5 which return the light so that separate images of lamp 1 are formed at 1<SP>1</SP> and may be observed through polarizer 10<SP>1</SP> by reflection at transparent plate 6. An A.C. voltage is applied to quartz plate 9 so that the beam focused on the mirrors is modulated in intensity, and the distance of mirror 4 can be determined from the axial displacement thereof necessary to equalize the brightness of the two images. Mirror 5 in another embodiment is convex and disposed near lens 3. A further form is shown in Fig. 3, where part of the modulated beam reflected by mirror 4 is focused by lens 3' and mirrors 12, 13, 16 on a photo-cell and another part of 'said beam is returned to the quartz modulator 9 and focused by lens 3 and reflectors 6, 14 and 16 on the photo-cell. A flicker diaphragm 17 ensures that the part beams are alternately incident on the photo-cell. The distance of mirror 4 is again determined by equalizing the image brightness either by displacing mirror 4 from the distant point or adjusting the freauency of the modulator 9 as by a feed back from photo-cell 8<SP>1</SP>. A Kerr cell may replace the quartz plate.
