Abstract: 990, 892. Film magazine orientation indicators. EASTMAN KODAK CO. Jan. 14, 1963 [Jan. 15,1962], No. 1549/63. Heading G2E. A camera has an externally visible indicator co-operating with means on a reversible magazine to indicate which half of the magazine film is positioned for exposure. The reversible magazine is of the kind used for film to be exposed in two longitudinal columns. An indicator 20 is marked with numerals "1" and "2" viewed through window 24 in the camera body to indicat the first and second exposure positions, and pivots at 21 being spring-urged towards stop 23. Aperture 28a in the magazine chamber wall 28 allows indicator 20 to protrude into chamber 26 and contact the asymmetrical magazine 25 whose chamfered edged 27 contacts indicator 20 in position 1 as in Fig. 1. When the magazine is removed as in Fig. 3 numeral "1" is again shown and this ambiguity is avoided by use of a 3-position indicator in which the chamfer is dimensioned to give a position "1" differing from the empty position of indicator 20, or by use of a footage dial. Indicating positions may alternatively be selected by means of electric contacts completing a circuit by engagement with an asymmetrical magazine surface with inlaid conductors. Another 3-position embodiment has a pivoting indicator with a sensing arm carrying a permanent magnet which is attracted by an asymmetrically placed magnet in the magazine. A footage dial 41 is combined in Fig. 8 with a magazine position indicator whose spring-loaded arm 46 is in fixed relation to sensing arm 44 which engages the magazine at a symmetrically placed notch 49. Position numerals "1" and "2" are viewed with footage numerals through window 48. Drive means of the pawl and ratchet kind for the footage dial are described. In moving from position "1" to position "2", indicator arm 46 engages and rotates dial 41 to show the new footage in the reversed magazine. U.S.A. Specification 2,186,926 is referred to.

Title: Improvements in apparatus for the objective determination of the refraction of the eye
IPC: A61B3/103
Filed: 1934-01-18
Abstract: 430,761. Sight - testing apparatus. REASON, R. E., and KAPELLA, Ltd., 104, Stoughton Street, Leicester. Jan. 18, 1934, No. 1751. [Class 97 (i)] Apparatus for measuring the refraction of the eye or the orientation of the axis of curvature of any cylindrical component of the eye, comprises an adjustable projecting system for directing light through a marginal area of the pupil so as to form a retinal image of a target, and an observing system for viewing the retinal image along an axis inclined within the eye to that of the projecting system, the observing system comprising an objective for forming an intermediate image of the retinal image, a lightdividing device substantially in the plane of the intermediate image for dividing the image - forming rays into two or more parts, a reversing system through which some of the rays are passed, a second objective system for forming a further image in which the relatively-reversed parts are adjacent in one direction, and a device substantially in the plane of this image for recombining the rays so that they can pass through a continuous area of the observer's pupil. In the form shown in Fig. 1, an image of a target 3 illuminated by a lamp 1 and condenser 2 is projected by a lens 4 and reflectors 5, 6 through a marginal area 9 of the pupil 10 to form a retinal image 7 which can be focused by displacing the target 3 along the axis 11. The image is viewed by an observing system coaxial with the eye, this system comprising an objective 13 forming an image of the retinal image in a plane 14, in which plane is situated a biprism 16 dividing the rays into two parts, and a field lens 15. The divided beam then passes through the first component 20 of an objective 20, 21 and through apertures 17, 18 in a diaphragm 19. One part of the divided beam then passes through a reversing prism 23 and the other part traverses a compensating plate 23A, both parts being received by the component '21 of the objective which forms an image consisting of two relatively-reversed parts in the plane 22. In this plane is placed a field lens 24 and a recombining biprism 25 which deviates the two incident beams so that after traversing the lens 26 they pass through the same area 27 where the observer's eye is placed. The lens 20 is preferably so situated that its front focal plane coincides with the image 14, so that the reversing prism 23 is disposed in parallel light. Alternative means are described for dividing the image-forming beam, reversing one part relatively to another and recombining the parts. For example in Fig. 5, the rays are divided by reflection at two faces of a cube 34 one part undergoing three reflections in a roof-prism 35 and the other part being subjected to two reflections in a right-angled prism 36. The rays are focused by lenses 20, 20A, and are recombined by reflection at the other two faces of the cube 34. Specification 413,029 is referred to.

Title: Improvements in or relating to pneumatic cushioning or shock absorbing devices for vehicles
IPC: F16F9/02
Filed: 1920-09-22
Abstract: 174,374. Holmes, B. B. June 19, 1920. [Convention date]. Pneumatic springs.-A pneumatic cushioning- device for vehicles comprises a reservoir, a chamber of variable volumetric capacity, a second chamber of variable capacity, which is subjected to greater pressure variations than the other for a given relative movement of the parts and which communicates with the reservoir, and a restricted means of communication between the chambers. Fig. 1 shows metallic bellows 10 secured at its upper end to a flange 9 on a steel cup 8 on a bracket 6 attached to a rear axle 7. A steel tube 11 surrounds the bellows and has a head 12 threaded thereon, and a flange 13 at the base over which the bellows is spun and to lugs on which the shackle of a leaf spring 20 is attached, a rubber buffer 21 surrounding the upper bush. The cup 12 has a boss 22 threaded to carry a sleeve 23, between which and the cup 8 is preferably a lubrÝcating-bush 24, the fit not being air-tight. The sleeve 23 has screwed to its lower end a spider 25 .carrying a disc-valve 26 guided on a shouldered bleed-tube 27 formed with a seat 29 for a valve 30 provided with a groove 31 and depending stem 32 adapted to contact with a pad 33 on the bottom of the cup 8 to open the valve against its spring 34. Air is pumped into the device through a valve port 37 to a pressure sufficient to support the maximum load. Owing to the restricted passage between the chambers A, B, running shocks tend to increase the pressure in chamber C until ordinary rises of pressure in the chamber B fail to open the valve 26. The riding position of the device is thus lowered until the stem 32 contacts to open the bleed valve, which remains open until the pressure in chamber B is raised sufficiently to allow this valve to close. To increase the dashpot effect of the chamber B owing to the rise of pressure therein being greater than in the chamber A, unless relieved by flow to the chamber C, the spider 25 may have small air passages, and to vary the effect spiders with varying air passages may be used. Fig. 2 shows a device of the piston type, the casing 51 of which is threaded into a member 48 mounted on a spring horn 45 and clamps a buffer pad 52 thereon. A cap 53 closes the upper end of the casing and carries a tubular sleeve 55 which telescopes loosely with a tubular extension 60 of a piston 56 connected to the spring 46 by an offset link 59. An annular cupleather 62 surrounds the extension 60 and is clamped by a nut 63 and a spring-pressed rubber expander 64; or the cup-leather may be U-shaped and the nut omitted. The piston has a groove to receive a pad 69 from which an oil duct leads to the shackle bolt 57. The sleeve 55 carries a spider 25 and associated apparatus as in Fig. 1, and the space between the extension 60 and the casing 51 is filled with oil. The action of the device is similar to that of the device shown in Fig. 1.

Title: Process of and apparatus for the electrical separation of suspended particles from gaseous fluids
IPC: B03C3/40
Filed: 1932-01-25
Abstract: <PICT:0389237/III/1> <PICT:0389237/III/2> In a process for the electrical purification of gases, the suspended particles are charged by ionizing portions of the collecting electrodes, the gas flow being in a direction opposing the ionic discharge, and then precipitated in a corona-less field. An auxiliary permeable electrode placed in the path of the gas to be treated may be used to provoke the discharge, and may be earthed or charged to a potential higher than that of the collecting electrodes.  The collecting electrodes may consist of parallel plates having a small difference of potential between adjacent plates and being spaced close together so that the field intensity between the plates is high.  When alternating current is used, the spacing between the collecting electrodes is made so small that the length of travel of a particle of a given size, in a given time, before reversal of charge, is larger than the spacing between the electrodes.  Pulsating direct current is preferably used for the ionizing discharge, while direct current is supplied to the collecting electrodes for the precipitating field.  The collecting electrodes may be provided with projecting points or edges, or in the case of plates, the edges may be shaped to produce ionization.  In the arrangement shown in Fig. 1, alternating current is supplied to the smooth electrode 3 which projects axially into the tubular container 1.  The member 3 is provided with one or more points 6 directed to a perforated auxiliary electrode 7 which is attached to the container 1 at a point beyond the dirty gas inlet 2.  The suspended particles are charged by the alternating discharge from the point 6 and are precipitated by the field between the member 3 and the container 1.  In the arrangement shown in Fig. 2, the collecting electrodes consist of a series of parallel plates 12, 13, the plates 13 being earthed to the outer casing of the precipitator and the alternate plates 12 connected to a source of alternating current, for example a tapping on the secondary 21 of a transformer.  The gas is passed through an auxiliary electrode 10 which is supplied with alternating current from the secondary winding 21 at a potential greater than that supplied to the electrodes 12.  The ionizing discharge is provoked from the edges of the electrodes 12, 13. Alternatively, the auxiliary electrode may be earthed, and the alternate pairs of collecting electrodes supplied with alternating current, both being above earth potential.

IPC: F16F1/387
Filed: 1949-01-27
Abstract: 657,712. Resilient mountings; assembling rubber bushes. GENERAL TIRE & RUBBER CO. Jan. 27, 1949, No. 2317. [Class, 108(iii)]  In an antivibration mounting comprising inner and outer rigid coaxial members and an annular bushing of rubber between the members, the bushing comprises a plurality of outwardly extending solid tapered teeth united at their bases and extending substantially throughout the thickness of the bushing, the teeth being widest at their base portion adjacent the inner coaxial member, narrowest adjacent the inner surface of the outer coaxial member and gradually diminishing in width as they extend outwardly from the base portion. In the arrangement according to Fig. 4, an annular bushing 5 of rubber-like material comprises an inner annulus 6 having outwardly projecting teeth 7, which are complementary to inwardly projecting teeth 9 of an annulus 8, the rubber of the annulus 6 being relatively harder than that of the annulus 8. The mounting is assembled by radially compressing the bushing 5 through a tapered path 15, Fig. 1 of a mounting member 16, into a metal outer member 3 of the mounting and thereafter forcing a metal inner member 1, Fig. 2, at high speed, into the bushing 5, thereby effecting frictional adhesion between the rubber and the inner and outer members 1 and 3. The rubber and metal surfaces may be coated with a dried film deposited thereon from a hard drying material such as a solution of rubber chloride, a rubber isomer, or rubber derivatives capable of passing through a thermoplastic state, or other rubber to metal adhesive, prior to the assembly of the mounting, adhesion being obtained by rapid heating of the metal parts to the softening point of the adhesive. The bushing may be vulcanised and placed between the inner and outer members without compression and bonded thereto in any known manner. The teeth 7 and 9 may be vulcanised together or held by the radial precompression of the bushing. In a modification Figs. 6 and 7, (not shown) the bushing comprises a single annulus having outwardly projecting teeth, which if the bushing is com-. pressed radially, as above, have a height to width ratio of preferably less than two, or the annuli 6 and 8 may be separately moulded and cured and assembled together with or without a suitable cement.
