Title: Photographic Camera
IPC: G03B17/30
Filed: 1967-06-16
Abstract: 1,184,931. Photographic camera. VOIGTLANDER A.G. June 16, 1967 [June 18, 1966], No.28009/67. Heading G2A. A photographic camera using perforated roll film supplied in cartridges without spools contains a film transport mechanism and co-operating locking mechanism for the camera back comprising Figs. 1 and 2 a winding wheel 6 geared to a film sprocket 14 to advance film from the cartridge 11 to take-up chamber 15 while the tooth 23 also geared to wheel 6 advances the exposure counter disc 5 which can be viewed through aperture 4. On completion of the exposure of all the film from cartridge 11, further rotation of the winding wheel 6 in the same sense produces a change in gearing by means of a cam wheel 50 Fig.4 below the counter disc 5 causing a reversal in the rotation of film sprocket 14 and transporting the film back into the cartridge. At the same time a further cam 56 Fig. 6 below the first cam actuates a locking device 9 by moving the lever 59 thus preventing the back of the camera being manually opened during the re-winding of the film into the cartridge. When the re-winding is complete the lever 59 is further actuated by cam 56 to unlock and open the camera back for removal of the cartridge. Opening of the camera back also causes release of the counter disc 5 from the pawl 37 allowing the disc to return to its initial position under the tension of a spring. Two forms of camera back locking mechanisms are described.

Title: A spring coiling machine
IPC: B21F33/04
Filed: 1934-10-01
Abstract: 446,895. Making upholstery springs. PASS, H. C., 1989, Queen Street East, Toronto, Canada. Oct. 1, 1934, No. 28016. [Class 83 (iv)] In a coiling-machine for producing upholstery springs with radially inturned ends the wire is fed between rolls 17, 28 which can be separated at predetermined intervals by a cam to interrupt the feed. A guide sleeve 80 presents the wire to a grooved roller 56 which curves it downwardly to form the spring the diameter of which is determined bv the vertical adjustment of the roller in respect to the guide sleeve and by the base diameter of a replaceable cam 39 which moves the roller towards the sleeve when the spring ends are to be bent. This cam is driven by skew gearing from a longitudinal shaft 30 driven by skew gear on a transverse shaft 10 operated by a motor 24 and the shaft 30 carries cams 33, 34 which swing the arm 54 carrying the roller 56 outwardly to determine the pitch of the spring and move it vertically to bend the ends after the roller has been advanced towards the sleeve 80. A third cam 32 operates a knife 73 to sever the completed spring. Adjustable sectors can be secured to the cams 33, 34 and to the cam which separates the feed rolls to produce springs of varying shapes.

Abstract: 1305349 Radiant energy velocimeter SINGER CO 15 June 1971 [4 Nov 1970] 28052/71 Heading H4D In a velocimeter of the type described in Specification 1,043,791, light from a coherent source 13, Fig. 1, is directed on to the relatively moving surface 15 to give scattered light lobes 16 which are received back at station 10 to sweep past the photo-detectors with a speed indicative of the relative velocity as a vector, i.e. direction and magnitude, the scattered light is passed through two sets of moving gratings, the lines on the two sets of gratings being + and- 45 degrees with respect to direction of movement of the gratings (which direction is taken as the "along-track" direction, to give rise in respective photo-detector outputs to signals at respective frequencies F 0  + F 1  and F 0  + F 2 , where F 0  is the frequency due solely to the movement of the gratings and would be the frequency of both outputs if there where no relative movement between 10 and 15, and F 1  and F 2  are component frequencies due to any such relative movement and are only equal if the "cross-track" velocity (90 degrees to the 'along-track" direction) is zero. The "alongtrack" velocity is given by and the "cross-track" velocity by F 1  - F 2 . The frequency offset generator 20, incorporating the moving gratings may comprise, Fig. 2, a moving continuous band 22 carrying the alternately arranged gratings 23, 24 as shown in Fig. 3. The photo-detector 27 then gives alternate output at F 0  + F 1  and F 0  + F 2 . A light source 31 and photo-detectors 33 use the alternate opaque and transparent edge strip sections 25, 26 to give a grating indentification or "left/right sequencing" signal 81. The band drive can also drive an F 0  signal generator 35. The outputs of the two photo-detectors and signal generator are fed to the frequency tracker 80, Fig. 4 (not shown), where the (F 0  + F 1 ) and (F 0  + F 2 ) signals are separated out, using the "left/right sequencing" signal and then converted to equivalent analogue voltages for use in subtracter circuits (with the similarly converted F 0  analogue voltage) to give (F 1  - F 2 ), F 1  and F 2 , the latter two being then averaged to five The gratings may alternatively be on respective rotating discs 128, 129, Figs. 5, 6, with the areas of detection shown at 139 and 140. The reference signal F 0  is then given by light source/detector pairs 141, 143. The gratings may also be formed on transparent drums 248, 249, Fig. 8, the scattered light passing through the cylinder at one end and the reference signal pairs being at the other end. In a third embodiment, Fig. 9, the gratings 260, 261 are fixed and the scattered light lobes are moved past them by means of rotating prisms 262, 263. - In the embodiment of Fig. 10, the moving grating strip, similar to that in the embodiment of Figs. 2 and 3, is carried on a support 357 which is rotated about a vertical plane under the control of the cross-track velocity signal, until this signal is zero and the plane of the support &c. is aligned with the velocity vector.

Title: Improvements in and relating to radio-telegraphic direction finding and similar methods and arrangements
IPC: G01S3/14
Filed: 1925-11-07
Abstract: 267,575. Watt, R. A. W., and Robinson, J. Nov. 7, 1925. Directive signalling; thermionic amplifiers.- In order to eliminate the effect of quadrantal error, or other aberrations due to lack of symmetry in the receiving circuits of direction-finding installations, wherein the input voltages from a plurality of aerials are separately amplified, as for example in the type of apparatus described in Specification 252,263, means are provided in the amplifier circuits for varying the ratio and, if necessary, the phase-relation of the amplified voltages. For instance, a variable tapping A, A<1> on the plate resistances R, R<1> may be employed to reduce the overall amplification from one or other of the directional aerials without introducing any phase difference in the output voltages. Or a variable grid leak may be used to give a similar control. Or the variable capacity C, C<1> included between the grid and filament connections of the first valve amplifier may be made only a fractional part of the total aerial capacity. Alternatively variable impedances or absorption traps L<1>, C<1>, R', Fig. 2, may be coupled to the plate circuits of the amplifiers so as to compensate for any input irregularities. Any phase-differences so introduced are removed by means of a phase-shifting device S<1>, one primary winding of which is directly included in the output circuit of one amplifier, whilst the other primary winding forms part of a resonant circuit coupled to the output of the associated amplifier.

Title: Improvements in the manufacture and production of carbonyl compounds
IPC: C01G49/16
Filed: 1924-11-26
Abstract: 244,895. Johnson, J. Y., (Badische Anilin & Soda Fabrik). Nov. 26, 1924. Iron carbonyl is prepared by passing carbon monoxide at a pressure above about 50 atmospheres over reduced iron at such a rate that the gaseous reaction product contains only from 2 to 8 per cent by volume of iron carbonyl whereby condensation of the latter upon the reduced iron is prevented. In an example, roasted pyrites containing small amounts of sulphur and copper besides iron oxide is reduced by means of hydrogen and after cooling to 200‹ C. carbon monoxide is passed over it at 200 atmospheres. Most of the iron carbonyl is condensed by cooling the reaction gases and the residual carbon monoxide, after removal of the uncondensed carbonyl by means of active carbon, is returned to the reaction apparatus without releasing the pressure. In another example, carbon monoxide is passed over reduced iron at 180‹ C. and at a pressure of 100 to 200 atmospheres. The activity of the iron is increased by the presence of aluminium, bismuth, nickel and other metals reduced to the elementary state. The reaction is also facilitated by adding water vapour or mercury vapour to the carbon monoxide Salts such as iron carbonate- or oxalate may be used in the preparation of the reduced iron. In place of pure carbon monoxide gases containing the latter and another gas such as hydrogen, e.g. water gas, may be used. Specification 17608/08 is referred to.

Title: Improvements in or relating to platinum- or palladium-containing reforming catalyst
Inventor: BARRETT WAYNE THOMAS
IPC: B01J37/03
Filed: 1954-10-04
Abstract: A hydrocarbon reforming catalyst is prepared by contacting a cracking component comprising silica and at least one of the metal oxides alumina, zirconia, magnesia, and thoria with an aqueous solution of a reducible compound of platinum or palladium, maintaining the cracking component in contact with the aqueous solution for 3-288 hours under substantially non-evaporative conditions at an elevated temperature up to the boiling point of the solution, and then drying and reducing the deposited platinum or palladium compound to the metallic state. The platinum or palladium compound becomes associated with the cracking component in a manner such that not more than 50 per cent of the compound can be removed by washing with water prior to reduction. The amount of platinum or palladium in the final catalyst is 0.1-2.5 per cent by weight.  Before contacting with the solution, the activity of the cracking component is reduced by the methods described in Specification 686,641, by varying the amount of metal oxide combined with silica, or by incorporating an alkali metal compound.  The cracking component may be covered with chloroplatinic acid solution, centrifuged after 1/2 hour, then heated for 3-48 hours at 190 DEG -230 DEG F. in covered containers or in a closed non-circulating oven, dried in nitrogen, and reduced in hydrogen; the centrifuging step may be omitted if the solution is sprayed on to the cracking component.  Another method is to immerse the cracking component in excess of the impregnating solution, preferably at 190 DEG -210 DEG F. for 16-48 hours, before drying and reducing.  The catalysts are especially suitable for reforming hydrocarbon fractions boiling in the gasoline-kerosine range.
