Title: Automatic counter-actuated apparatus for taking and developing photographs
IPC: G03B17/53
Filed: 1971-05-24
Abstract: 1292781 Automatic double camera PHOTOME INTERNATIONAL Ltd 24 May 1971 [23 May 1970] 16746/71 Heading G2A An automatic coin-operated photographic apparatus has a double camera construction, one camera having a single lens assembly for taking single relatively large photographs, and the other camera having four lens assemblies for taking four smaller photographs, some possibly being of a picture which may be mounted on the apparatus. The apparatus is housed in a cubicle (1), Fig. 1 (not shown), and in the upper part is a box 20 containing a roll of reversal paper E. This is led down between rollers 40, 42 to pass into camera C just in front of a masking sheet 27 and then into camera D just in front of a masking sheet 28. These masking sheets produce suitable borders to the photographs when illuminated by lamps 29 or 30. The single lens assembly 25 of the upper camera has its own diaphragm setting means, whereas the four lower lens assemblies 26 have their diaphragms set simultaneously by means actuated by a wheel 33. In correspondence with the upper camera C are two slide projectors 35, into which slides 39 can be inserted, and the images on these slides can be projected via a mirror (36), Fig.7 (not shown) on to the film in camera C. If a single large photograph is required, a coin is inserted into the appropriate slot (11), Fig. 1 (not shown), the film is fed down to the separation level between the two cameras, where a cutter 43, 44 severs the portion of the film below itself, and leaves the apparatus set for the photographing step. The rear bulb 29 is energized to expose the border, the main bulbs (9) energized to light the subject, and then the film is fed down through the lower camera into engagement with its conveyer rollers 54, 57. The cutter is operated again, and the severed length of film is then passed on into the processing part of the apparatus. If four smaller photographs are required, then, after inserting the coin into the corresponding slot, rear bulb 29 is energized to expose the outer border, and the film passes into the lower camera D where rear bulb 30 exposes the dividing borders between the four picture areas. The main bulbs 9 illuminate the subject, and the four exposures are made, either simultaneously or separately. The length of film is then cut off and delivered to the processing section as before. If only two small photographs are required, together with two pictures derived from the slides 39, these latter are made in the upper camera, and the film then transferred to the lower camera, where only the two lenses corresponding to the unexposed areas are used for the subject exposure. If only two of the small photographs are required, together with two blank spaces for future use, two additional bulbs (60), Fig. 8 (not shown) shielded by opaque screens (61) expose two of the picture areas, leaving the remaining two areas for photographs in the normal way.

Patent GB-677109-A (GB)
Title: Air line lubricator
IPC: F16N7/34
Filed: 1950-07-06
Abstract: 677,109. Air line lubricators. NORGREN CO., C. A. July 6, 1950 [July 14, 1949], No. 16939/50. Class 12 (iii). In an air line lubricator, a blade - shaped metering assembly is disposed within an air passage and can be rotated, thereby controlling the rate of oil flow. An air passage 11 contains a metering assembly 26, of which the upper and lower portions 29, 31 are cylindrical, while the centre portion 32 is in the form of a blade. The blade 32 may be rectangular in cross-section or the upstream and downstream edges may be bevelled so that it is approximately a parallelogram. Such changes in shape vary the pressure reduction obtained per degree of blade rotation, and hence control the metering characteristics of the lubricator. A transparent cylindrical sight gauge 42 surrounds a needle valve 48. The metering assembly 26 may be rotated, accidental movement being prevented by a set screw. Air passing through the tube 11 enters an orifice 64 in the blade 32, and thence goes via a passage 66, a groove 67, a further passage, not shown, and a check valve to a bowl 19. Lubricant in the bowl is thereby forced through a tube 59 and a valve 58-which latter prevents downward flow of lubricant-and passages 56, 57, 54, 53, to the valve 48. From the valve 48, the lubricant passes through the sight gauge 42 and thence by passages 63, 62, 61 out of the downstream edge of the blade 32. A filler plug is provided and co-operates with the check valve in the inlet air passages of the metering assembly in such a way that replenishment of the bowl 19 with lubricant is possible even while air is passing through the passage 11. The lubricator is adjusted by first opening wide the needle valve 48 and rotating the metering assembly 26 until a flow of lubricant slightly in excess of that required is observed in the sight feed gauge 42. The final adjustment is made by gradually closing the needle valve 48. The direction of air flow through the lubricator may be reversed, the metering assembly 26 being rotatable through 180 degrees.

Abstract: 172,009. Moritz, R. Nov. 23, 1920, [Convention date]. Void [Published under Sect. 91 of the Act]. Sulphuric acid.-In the tower process of making sulphuric acid, in order to render the intensity of the reaction as uniform as possible throughout the series of towers the latter are provided with surfaces capable of withdrawing or supplying heat. As shown in the Figures, this exchange of heat is effected by means of lead tubes 5, 6, 7, water from the tubes in the hottest towers being used to supply heat to the cooler towers. The towers are preferably of rectangular section and the acid-proof filling is so designed as to allow the gases to be distributed uniformly. The towers are divided into compartments by the semi-pervious partitions 4 which are made of ceramic material and are pierced with small holes which allow the liquids to pass through but practically no gases and compel the latter to travel horizontally. The lead tubes 5 are lodged between the specially constructed filling so that the tubes may be withdrawn without stopping the process. The water discharged from the tubes may be used to cool the outside of the towers. Irregular filling-elements may be employed when heating or cooling is not desired actually amongst the filling.

Title: Black level clamping circuit for a television signal processor
IPC: H04N5/18
Filed: 1975-04-25
Abstract: 1511003 Television RCA CORPORATION 25 April 1975 [1 May 1974] 17250/75 Heading H4F A circuit for clamping the pedestal of a television video signal to a reference level includes a capacitor to which the signal is applied, the capacitor being charged from a low impedance source of reference potential via a unidirectional device, e.g. a diode. The reference source is so designed that the signal cannot be clamped to the level of a noise pulse that exceeds the pedestal level. In the embodiment shown, Fig. 1, the luminance signal of a colour video signal is passed via an amplifier 36, which has a low output impedance, to a capacitor 42. A low impedance black reference potential source 46, which includes a resistor 68 as the emitter resistor of the output transistor 64, supplies the current to charge capacitor 42 via diode 67. The luminance signal is also applied to sync. pulse separator 24 which causes switch 72 to earth the emitter of transistor 64 during each sync. pulse to prevent charging, so that the pedestal level rather than the sync. pulse level is clamped to the reference potential. The time constant of the charging path is so chosen that the capacitor charges slowly relative to the duration of a noise pulse. Thus, during a noise pulse the current flowing through diode 67 increases to a value equal to the current available through resistor 68. Transistor 64 is cut off with the result that capacitor 42 can only charge through the relatively high impedance of resistor 68. The circuit thus clamps rapidly to the reference potential source but remains relatively insensitive to noise pulses.
