Patent GB-108093-A (GB)
IPC: F04F5/42
Abstract: 108,093. Schmidt, H. F. Nov. 30, 1916. Aspirating apparatus; nozzles, cones, and combining-tubes.-Relates to apparatus for purposes such as the ejection of air from condensers and employing an elastic inducing fluid, such as steam. The inducing-fluid passes by an annular series of nozzles 1, Fig. 1, formed by tangential partitions in an annular chamber, into a vortex chamber 2, moving in a spiral path therein and accumulating pressure at the expense of kinetic energy until able to discharge, with the induced fluid, against the external pressure. Induced fluid enters the casing 3 by a port 4, and inducing- fluid by a port 5, passing through the nozzles into the vortex chamber 2 which communicates around its inner periphery with, and draws induced fluid from, a central chamber 6, the combined fluids passing from the outer edge of the vortex chamber into a spiral pressure or delivery chamber 7. By means of a by-pass 9, induced fluid is supplied to both sides of the central chamber 6, in order that the groups of inducing-fluid nozzles 1 on both sides may be equally effective. Accelerating nozzles 10, similar to the inducing-fluid nozzles, receive pressure fluid from a port 11 and expand it to the pressure normally existing in the central chamber. Modifications comprise the provision in the vortex chamber of an annular series of diffusers formed by the lateral walls of the chamber and transverse vanes, which may be adjustable to the stream-line contours for various rates of discharge, and also the arrangement of similar vanes 15, Fig. 5, to form diffuser tubes uith straight sides, whereby the apparatus acts as a number of ejectors, each having one or more nozzles and a diffuser, arranged in an annular series and operating in series. Alternatively the nozzles 1 and 10 may be without the tangential partitions; so that the delivery is radial, in which case the pressure-chamber vanes also will be radial. These vanes may be curved, or may terminate before reaching the inner periphery of the vortex chamber. According to one arrangement, the nozzles 1 are omitted.

Abstract: 947,163. Photographic cameras. VOIGTLANDER A. G. March 28, 1960 [March 28, 1959], No. 10971/60. Heading G2A. In a photographic camera the exposure time adjusting member and/or diaphragm adjusting member of which is adjusted corresponding to the indication of a built-in photo-electric exposure meter by means of a device which scans the position of the exposure meter pointer and which in its scanning motion abuts against the pointer and is stopped in a position determined thereby, the measuring instrument of the exposure meter is arranged in a housing on which is secured a mirror which redirects a beam of light from the instrument pointer into the viewfinder of the camera. As shown (Figs. 2, 4, 6) the position of an exposure meter pointer 7 moving over a transparent plate 9 in a galvanometer housing 1 is made visible in a viewfinder 20 by means of a mirror 14 placed behind a window 13 in camera cap 15,by a mirror 19 secured to housing 1, and by a glass body 21, which is let into a glass block forming part of the viewfinder 20 and which has a toric lens surface 22 and a reflecting surface 23. The ends 10 and 11 of plate 9 are coloured so as to indicate when conditions are unsatisfactory for proper exposure. The camera is operated as follows. On winding-on the film,by means of a rack and pinion coupling 53, 54 (Fig. 5), a slide 46 is moved to the left against the tension of a spring 55,until a catch 57 engages in a recess 56. The shutter speed and film sensitivity rings 65, 67 are set to the desired values on fixed scales 64, 68 respectively, whereby grey density wedges 66, 69 are adjusted in front of the photo-cell 71 connected to the galvanometer in housing 1. On depression of a camera release 32, by means of co-operating pin 31 and spring urged lever 29, a clamping bow 27 is pivoted so as to lightly clamp the pointer 6 against an overlying clamping surface. On further depression of release 32, by means of a projection 58 co-operating with the catch 57, the slide 46 is released, runs down to the left, adjusts the diaphragm aperture by means of rack and pinion coupling 60, 61, and moves the scanning lever 37 across the measuring range of pointer 6. The scanning lever 37 is pivoted at 36 on disc 35, is lightly urged by spring 38 into abutment with a stop 39 thereon, and is coupled to the slide 46 by way of a shaft 34, a disc 43, and a bar 49 sliding in a groove 50 in the disc 43 and pivoted about a point 47 on slide 46. On engagement of lever 37 with pointer 6, by means of projecting pin 40, the said lever is pivoted slightly away from stop 39 and becomes jammed between a friction surface 42 and its pivot point 36. Further movement of slide 46 is thereby prevented, and the diaphragm is as a result set to a value in accordance with the measured light value and the present values of exposure time and film speed.
