Abstract: 1,024,083. Machine frames. A. MOOSMANN. Sept. 14, 1962 [Sept. 15, 1961], No. 35161/62. Heading B3B. [Also in Division F2] A guide for a machine tool table comprises bearing-rails 4, 7 and 9, 11 of truncated triangular cross-section treated in correspondingly shaped grooves in the machine table and frame and secured by screws 5, 8 and 10. Rolling members such as balls or rollers 14 and 17 are located between rails 4 and 7 and 9 and 11 respectively. The rail 11 and its corresponding groove are tapered longitudinally to facilitate adjustment by means of a screw 13 so as to adjust the clearances or preload the rolling elements. In an alternative embodiment an intermediate rail member is located between each pair of bearing rails and one of the rail assemblies may be inclined at 45 degrees transverse to its axis so that the carriage guide may offer transverse and vertical restraint and at the same time permit expansion and contraction due to temperature fluctuations.

Title: Improvement in roll film holders
IPC: G03B1/66
Filed: 1966-08-05
Abstract: 1,113,400. Toothed gearing. GRAFLEX Inc. 5 Aug., 1966 [6 Aug., 1965], No. 35204/66. Heading F2Q. [Also in Division G2] A sun and planet gearing arrangement is provided for transmitting rotary motion from a film-winding lever 20 to a drive element 17, which both winds on the take-up spool and also drives a footage or exposure counting indicator 15. As shown, a ring gear 21 having internal teeth is mounted with a pawl 19 engaging the teeth so as to allow rotation of gear 21 in one direction only. A carrier assembly 23 having a pair of upright studs 24 is disposed within gear 21, the studs engaging in apertures 25 in the hub portion 26 of winding lever 20, so that the carrier rotates with the lever. Planet gears 27 are mounted on studs 24 so as to engage with the teeth of ring gear 21. A sun gear 28 meshes with the two planet gears, and is coupled to the drive element 17. In operation, lever 20 is rotated counterclockwise. Ring gear 21 is held fixed by pawl 19 against this rotation, so that the planet gears 27 are rotated by being driven on the teeth of gear 21. This rotation is transmitted to sun gear 28, and hence to element 17, and so to the film wind and indicator 15. A restoring spring 29, engaged by a stud 41 on carrier 23, is also tensioned by this rotation. When lever 20 is released, the spring acts to restore the parts to the original position. Element 17, and hence sun gear 28, is now held fixed, against any reverse movement, by means not shown, and hence the ring gear is rotated by the planet gears, as carrier 23 is rotated by spring 29 back to the starting position.

Title: Process and apparatus for purifying exhaust gas
IPC: C01D5/14
Filed: 1972-07-27
Abstract: 1385719 Purification of exhaust gases HITACHI Ltd 27 July 1972 [6 Aug 1971] 35219/72 Heading ClA Exhaust gas containing a noxious substance such as SO 2  or NO 2  is reacted with an absorption solution to absorb the noxious substance, converting the noxious substance into an innocuous substance, and bringing at least part of the resultant mixture into direct contact with the entering exhaust gas stream in order to cool the exhaust gas and form a solid substance from the mixture. The absorption solution may be aqueous sodium sulphite possibly containing caustic soda which has been recovered after reaction of caustic soda with SO 2 . In the drying tower the heat of the flue gas evaporates water from the solution leaving a fine powdery Na 2 SO 3  product which may be recovered. The cooled gas is passed to an absorbing tower where it is contacted with an absorption solution containing NaOH or Na 2 SO 3 . The spent absorbent may be circulated to the drying tower or caustic soda may be added to it to convert any NaHSO 3  present into Na 2 SO 3 . Nitrogen oxides present in the waste gas may be converted by NaOH into sodium nitrate or by Na 2 SO 3  into sodium sulphate. Alternatively part of the spent absorbent may be reacted with slaked lime or CaO (as powder or slurry) to form calcium sulphate or calcium sulphite.

In one form of reflector, Fig. 2, looking from beneath, the sides 6 are parabolic in section with asymmetric axes X<SP>1</SP>X<SP>1</SP> X<SP>2</SP>X<SP>2</SP>, parallel to vertical planes through which the light from a lamp filament at the common focus 5 is mainly directed, downwardly and angularly across the street. Depending. parabolic reflectors 9 at the smaller end 8 of the reflector reflect direct light from the source and light reflected from the larger end 10 in the directions of the asymmetric beams. The light source is preferably nearer the smaller end 8 of the reflector and, to avoid glare, above the level of the lower edge of the reflector. In vertical cross-section 'the reflector may take the form of opposing elliptic curves.' The reflector may be formed from a sheet metal annulus resiliently secured and deformed into shape in a suitably apertured plate functioning also as a holder or maintained in deformed shape by upsetting the metal.

Abstract: 448,709. Resilient engine mountings. SOC. D'EXPLOITATION DES BREVETS L. SIMON (AMORTISSEURS SANCHOK) SOC. ANON., 9, Rue Boissy d'Anglas, Paris. Dec. 18, 1934, No. 36339. Convention date, July 4. [Class 122 (iii)] [See also Groups XXXI and XXXII] In a system for absorbing vibrations produced by a power plant, the machine &c. is mounted rigid with a platform which is elastically suspended in all directions, and is combined with an independent system of shock absorbers to limit the vibrations. The machine M is carried upon a platform P, the longitudinal members 1 of which are supported by vertical elastic supporting members E1-E4. Each comprises a rigid arc-shaped support 2 with an upper, annular, oil chamber provided with a concave, spherical bottom 4. A rod 9 is supported in the chamber by a bearing 5 secured to a sleeve 7 which is fixed to the rod and carries a lid 8. A spring-pressed sleeve 10 with a convex spherical bottom 12 which forms the bottom of an oil cup 11 is mounted on the rod 9 and supports a tubular member 16 provided with a bearing 21 and a bracket 18 by which it is secured to the member 1. Platform P oscillates vertically on springs 14 and horizontally on ball-and-socket joints 4, 5, 12, 21. Horizontal displacement is stabilized by pairs of devices S1, S<1>1 ... S4, S<1>4. These comprise rods 29, Fig. 6, carrying relatively fixed and movable spherical bearings 45, 23 which engage seats communicating with oil chambers 24, 35, 40, 43 in parts 22, 27. The part 22 is fixed to the ground and the frame 1 carries the part 37. A safety cushion 28 of plastic material is arranged. as shown. Shock absorbers V1-V4, H1-H4 are provided to act upon the vertical and horizontal oscillations respectively. The arms of the shock absorbers are connected to fixed points through links and ball-and-socket joints. The absorbers are preferably of a kind, the efficiency of which increases as a function of the speed. Amplifying devices, such as two-armed levers, may be interposed between the platform and the absorbers. The Specification as open to inspection under Sect. 91 describes a modification in which the platform is connected with a spring-pressed piston which is slidably mounted in a chamber to check vertical vibrations only. This subjectmatter does not appear in the Specification as accepted.
