Title: Improvements in or relating to machines for sealing acid bottles or the like
IPC: C03B23/057
Filed: 1942-06-03
Abstract: 559,616. Sealing bottles &c. JONES, O. W., and BROOME, J. H. June 3. 1942, No. 7546. [Class 125 (ii)] Glass &c. containers for fire-extinguishing fluids &c. are sealed in a machine comprising a rocking bar 5, pivoted at 6, which moves spindles 11, 12 upwardly or downwardly through swivelling bearings 7, 13, 9, 10, to raise or lower the containers, rigidly held in cups 31, to heating flames from burners 53, 54. The spindles 11, 12 are constantly rotated from an electric motor through belts 16, 20 and pulleys 17, 18, 19 and the container-holding cups 31 are frictionally driven by the spindles through spring-pressed balls 33. The cups 31 may thus be held by hand while the containers are being positioned therein or removed therefrom. The holding means for the containers comprise parts 38, 39, pivoted together at 42 and biassed towards each other by a spring 48; a knob 47 permits the parts to be separated for positioning or removing a container. Needle valves 63, 64 govern the amounts of air and gas to the burners 53, 54, the carrying block of which is adjustable on a vertical rod 67. The burners are positioned so as to play upon the top portion of the neck of a container to be sealed, so to pre-heat the same, when the cup 31 is in the lower position, and when the cup is raised the burners play upon the lower portion of the neck of the container which is sealed by the operator, who, by means of pliers, pulls the heated neck upwardly. An adjustable spring- biassed toggle system 22, 26, 30 operates to hold the rocking bar 5 in one or the other extreme positions. A balance weight 21 counteracts the effect of the pulley 17. An alternative form of container-holding device comprises two pivoted parts 68, 69 biassed together by a spring 82 through a pivoted ring 78 which bears on ramps 76, 77. The parts 68, 69 may be opened for the positioning or removal of a container by depressing a thumb piece 84 on the ring 78. A further form of containerholding device comprises a pivoted spring- pressed lever with a forked end adapted to bear upon the bottle body.

Title: Method of and apparatus for controlling the moisture content of paper
IPC: G01N25/56
Filed: 1929-03-08
Abstract: 330,596. Klages, F. E. P. March 8, 1929. Drying.-A wet bulb acting thermostatically supplied with air drawn from the vicinity of a pulp-sheet substantially short of the completion of travel on the drying rolls, regulates the supply of heat to the dryercylinders thus controlling the moisture-content of the paper, board, &c. leaving the dryer. A fan 19, Fig. 2, with a motor 20 draws air through a slit 12a, Fig. 5, in a pipe 12 extending across the sheet E and supplies a box 14 containing a wet bulb 15, &c. The, wet bulb is connected by piping 22 to a diaphragm attached to a valve controlling a compressed-air supply for valve-operating motors 32 and 33. Exhaust steam passes from a supply pipe 10, through a valve 34 to an outlet 37, or through a pipe 36 supplying the dryer - cylinders, a manually operated valve 38 and a live steam valve 35 being normally closed. An increase in the moisture of the air supplied to the wet bulb increases the pressure in it and opens the valve to increase the supply of compressed air to the motor 32, thus closing the valve 34 and increasing the supply of exhaust steam to the dryercylinders. Further compressed-air supply opens the live steam valve 35. Included in the compressed-air system is a reducing valve 43 and a three-way valve 30 which carries a switch for the motor 20. For temporary stoppage of the dryer, the valve 30 is operated to supply air from the reducing valve to maintain a reduced heat supply to the cylinders, the motor 20 being switched off.

Title: Improvements relating to the adjustment of movable machine parts
IPC: B23Q17/22
Filed: 1954-03-16
Abstract: 760,831. Electric indicating systems. LINDNER GES., H. March 16, 1954 [March 21, 1953], No. 7672/54. Class 40 (1). [Also in Group XL (b)] Apparatus for determining the adjustment of a machine part comprises a scale the graduations of which represent adjusted positions of the machine part, means for projecting an image of the graduation on to a pair of photo cells which give identical responses when the machine part is in the exact position corresponding to the scale graduation but which change in opposite senses when the part shifts and means for indicating the difference between the cell responses. As shown, a co-ordinate boring machine or jig-borer has a vertical boring spindle 3, a carriage 7 slidable on ways 5 and a table 8 slidable transversely on ways 9. For coarse adjustments of the carriage and table coarse scales 13, 14 are provided while, for fine adjustments, a pair of rods 15, 16 having a fine helical line inscribed on them are associated one with each of the coordinate movement and are adjustable by means of graduated drums 17. Fig. 2 shows the optical and photo-electric arrangements associated with one of these scales. Light from a source 18 is reflected by a flat glass plate 19 on to the scale 15 and an image of the helical line is projected via a. collimator 20 and telescopic system 21 on to a matt screen 22. The screen is in control box 12 mounted on the machine. The matt screen carries a pair of lines between which the image of the graduation should be located. The matt screen may be replaced by a microscope with a reticule in the focal plane of its eyepiece. Behind reflector 24 is a photo-electric cell divided into two parts the arrangement being that when the image of the graduation is between the lines of the matt screen the two parts of the cell are equally illuminated and meter 32 on the control box indicates a centre zero. The cell construction is shown in Fig. 4 and consists of a single cell having a barrier layer divided into two parts. The space between these parts is such that the graduation image 27 overlaps both cells thus one cell or the other gives a maximum reading if the image is off centre and the response of one cell falls while that of the other increases. Each section of the barrier layer cell is partially covered with a screen 30 which ensures that the output increases rapidly to a maximum as the image moves to one side of the centre and then falls off. The cells are connected in the differential circuit shown in Fig. 5, initial balance being obtained by a potentiometer 36. Unequal illumination of the two cells will produce a potential difference at points a and b which is "chopped" by a chopper relay 39 amplified at 41 and indicated on galvanometer 32. The response of the photo cells may control a power adjustment.

Filed: 1942-06-08
Abstract: 557,978. Aeroplane wing spars. COLE, W. June 8, 1942, No. 7758. [Class 4] The booms 2 of an aeroplane wing spar are of angular cross section of uniform thickness, the spars being in sections detachably connected together by ribbed plates which engage one another or separate ribbed plates and are held in engagement by screws, these plates being parallel to the flanges and web of the spar and arranged near the comers of the booms. The flanges of the spars taper in width along their length in accordance with the load upon the booms. Figs. 2 and 3 show a web 1 and two angular section booms 2 forming one side of a box-section member of a wing. Secured to the ends of each boom 2 on the inside are two plates 5, only two of the four being shown, these plates having alternate ribs and recesses engaging corresponding recesses and ribs in plates 6 which extend across the plates 5, on abutting spar sections, to which they are clamped by screws 7 and nuts 8. The edges of the plates 6 have slots 15 at one edge to permit the ready entry or withdrawal of the bolts attached to the removable section. The ribs on the plates 5, 6 are transverse to the spar and transmit bending moment stresses. Shear stresses are taken by similar plates 10, on the outsides of the webs 1, having longitudinal ribs, the plates on adjacent sections being sprained by correspondingly ribbed plates 11 and secured by screws 12 and nuts 13. One end of each plate 11 is cut away as shown at 16, Fig. 3, to permit passage of the screws 12 on the removable section. Packing strips 3 are arranged between the booms 2 and the outer skin. The abutting edges of the boom flanges are shaped as shown at 18, 19, Fig. 4 to facilitate alignment. To enable the spar sections to be more readily engaged, the plates 6, before the nuts 8 are tightened, may be yieldable under spring pressure, and the foremost tooth of the plate 5 on one section may be bevelled and made sufficiently broad so as not to slip into any of the recesses until the central recess in the plate 5 is reached, the bevelled end displacing the plate 6 against the action of its spring as the spar end is moved into position.

Abstract: 720,313. Beams; floors. UDALLS PRESTRESSED CONCRETE, Ltd. March 26, 1953 [March 26, 1952], No. 7768/52. Class 20 (4). A reinforced concrete beam is made by arranging reinforcements in a channel-shaped member, or more than one aligned channelshaped sections, the reinforcements being tensioned, against the compression reaction of the sections, before the in situ concrete is filled into, and above, the channel. As shown in Fig. 1, the sections 11 are open at one end and closed by a wall 13 at the other end, the wall having passages 15 for the reinforcements 17. The sections are aligned with grouting between them, with the wall 13 of each section against the open end of the adjacent section, except in the middle of the beam where two walls 13 abut. The reinforcements are tensioned, by any suitable means, and are retained by being embedded in concrete in the end sections. When the assembly so formed is in position in the building, the channels in the sections 11 are filled in with concrete which extends above the side walls of the channels and may be integral with in situ concrete extending laterally from the beams to form a floor. Some of the reinforcement rods may be tensioned after the setting of the in situ concrete to post-tension the same, and in some cases, the reinforcements may rise at their ends out of the general plane of the reinforcements. The sections 11 may have orificed walls 13 at both ends, and the concrete may be filled into the channels before the assembly is in position in the building. A number of beams may be laid side by side to form a continuous support for the concrete forming the floor which is post-tensioned by reinforcements running transversely to the beams. The depth of the beam may be increased as shown in Fig. 6 by side slabs 23 which may be retained in the permanent structure. The slabs 23 preferably have a corrugated or toothed lower edge to fit correspondingly formed edges of the sections 11. The sections 11 may each be in the form of a cross, Fig. 10, so that a grid-like structure may be built up, the reinforcements passing through holes in the walls 34 or through clearance spaces 35 beneath the walls.
