Heading F4J, A chimney comprises an outer shell 2 within which one or more flues 7 are laterally supported by wheels or rollers 6 attached to the outer shell 2 or to discs 8 through which the flues pass (Fig. 3, not shown), or to subframes 67 attached to the shell 1 (Fig. 13, not shown). Heat losses from the flues 7 are reduced by filling the void between flues 7 and the outer shell 2 with a loose fill of insulating material, e.g. vermiculite, by insulating support plates 9, discs 8 and caps 15 from the outer shell 2 or flues 7 and by covering the wheels or rollers 6 with a material having low heat conductivity. The wheels are mounted on spring bearings 12 to allow for variation in the external diameter of the flues 7 and can be attached to the shell 2 between jointing flanges 4 of adjacent sections of the shell, or the portion of the flue in the vicinity of the wheels 6 can be increased in diameter. Fig. 4, and the wheels 6 attached thereto. An embodiment is described (Fig. 13, not shown), in which a duct 68, similarly supported as the flues 7, has a refractory lined flue 69 similarly supported therein, said flue 69 being suitable for very hot gases. A natural draught, in the space between the duct 68 and the flue 69 serves to cool the outer surface of the flue. In a further embodiment, suitable for existing chimneys, expansible rods and corner pieces 54 for rectangular chimneys (Fig. 1, not shown) and expansible hoops 62 for circular chimney are forced against the wall and support the wheels 6 or the discs, on which the wheels can be mounted, by means of movable steel strips 56.

Abstract: 1,083,362. Carry mechanisms. BUCHUNGSMASCHINENWERK KARL - MARX - STADT, VEB. Jan. 27, 1965, No. 3561/65. Headings G4B and G4D. In a carry mechanism that can be selectively associated with any one of a plurality of accumulators 12, 13 or 14, 15, carries are temporarily stored by the unlocking of transfer pawls 23, until all the digits of a number have been entered by differentially moved racks, and are actually transferred, after the input racks have been disengaged, by releasing locking devices 34. In operation an adding or subtracting accumulator, e.g. 12 or 13, is swung into engagement with an intermediate wheel 2 meshing with one of the racks 1 and consequently as the accumulator completes one revolution a long tooth 18 or 19 by engaging with teeth 5 or 6 rotates a toothed member 4 and, by the corresponding rotation of a pawl 25, the arm 28 of a carry pawl 23 is released from a stop 30. The arm 28 is held against a pivot member 33 until all the digits have been entered and the pivot is then released so that the arm 28 rotates under the tension of a spring 26 and by the engagement of the teeth 27 with the next intermediate wheel 2, the carry is transferred to the place of next higher significance. To return the accumulators to zero the racks 1 are again brought into engagement with the wheels 2 and withdrawn until the long teeth 18, 19 engage the projections 5, 6. One of the other accumulators 15, 16 may be swung into engagement with the wheels 2 as the racks 1 are withdrawn to transfer the total from one accumulator to the other. The totals may be printed by a type carrier.

Abstract: 1,234,322. Photo-electric microscopes. SOC. GENEVOISE D'INSTRUMENTS DE PHYSIQUE. June 2, 1969, [June 17, 1968], No.27823/69. Heading G1A. [Also in Division G4] A photo-electric microscope for use in investigating masks used in the production of integrated circuits has a laser for its light source. The microscope optical system comprises a telescope 23 enlarging the cross-section of the beam, diverging lens 13, an oscillating mirror 15, lens 14 focusing the beam to form a scanning spot on the transparent mask, and lenses 21 and 18, directing the light transmitted by the mask to a germanium photo-cell 16. The output of the detector is amplified and shaped in circuitry 19, 20, the actual purpose and nature of which is not described. The microscope permits accurate location of marks in the form of transparent lines on the mask. Narrow lines produce triangular pulses; wider lines produce square pulses which require differentiating for determination of the accurate location of the marks. For coarse measurement, an interferometer system, using preferably the same laser 5 as its source, is used, comprising beam splitter 6 to direct light to prisms 7 and 8 and photo-cells 9, 10 whose pulse output is counted at 19. The interferometer measures the position of a movable table (2) which carries a further table (11) on which the rotatable mask support (12) is mounted, Fig.1 (not shown). Rotation of the table 12 thus allows distances at least in two directions at right angles to one another to be measured by longitudinal movement of table 2 by motor 4. During measurement the mask may be viewed by the operator by means of a closed circuit television system. The laser 5 again provides the source of illumination for the mask, via a ground glass screen 22 supplied by beam splitter 24. The TV camera 25 receives light through beam splitter 27 and also detects the oscillating scanning spot provided by mirror 15 and lens 14. If a "flying spot" TV system is used, mirror 15 can form the scanning mirror but cannot be used simultaneously for microscope measurement. Separate sources may be used for the TV system and the interferometer instead of the same laser 5.
