Filed: 1954-04-22
Abstract: 752,388. Measuring osmotic pressure. LKBPRODUKTER FABRIKSAKTIEBOLAG. April 22, 1954 [Sept. 4, 1953], No. 11678/54. Class 106 (2). [Also in Group XX] An interferometer employing a beam-splitting prism is used to measure the difference of level between two liquid surfaces in an osmotic pressure cell. As shown the cell K comprises arms J1, J2 containing the liquids separated by a semi-permeable membrane L. Light from a source A collimated by a lens D is divided by a beam-splitter comprising a semi-transparent reflecting layer F between prisms El, E2, the resulting beams being directed by reflectors G1, G2 on to the liquid surfaces respectively. The layer F is arranged so that the prisms E1, E2, reflectors C1, C2 and the liquid surfaces are respectively mirror images of each other with respect thereto. The beams reflected by the liquid surfaces are combined by the layer F and superimposed images of the surfaces are formed by a lens M in a plane N observed in an eyepiece O. Any difference between the two liquid levels gives interference effects visible in the eyepiece and which can be compensated by a compensator H2 placed in one of the beams and formed of two relatively movable prisms. A glass plate H1 is placed in the other beam to equalize the light paths.

[Also in Division D1] Corrugated board is produced from a web 1 of sheet material, e.g. paper, plastics material, textile fabric or leather, by feeding the web 1 between a pair of feed rollers 2 at a first predetermined speed, passing the web 1 between a pair of parallel conveyer belts 6, spaced from the rollers 2 in the direction of movement of the web 1, at a second predetermined speed lower the first speed to corrugate the web 1, applying adhesive to the crests of the corrugations on at least one side of the web 1, and feeding a covering web 9 to at least one side of the web 1 between the latter and the belts 6 to cause the web 9 to adhere to the corrugations and to hold them under compression. After passing between the rollers 2, each provided with radial incisions, the web 1 passes between parallel sheet-metal guide plates 3 which are partially overlapped by parallel limiting metal plates 4 which are vertically adjustable to the desired height of the corrugations of the web 1. Pivotally-mounted glueing rollers 8, each provided with radial incisions, project into apertures 7 in the plates 4 to apply glue to the crests of the corrugations. The speeds of the belts 6 and the rollers 2, 8 are adjustable in stepped or infinitely variable manner. To produce corrugations lying obliquely to the direction of movement of the web 1, the rollers 2 and the plates 3 are arranged in the same direction with respect to the oblique position of the corrugations to be formed, but less obliquely, Fig. 3 (not shown).

Filed: 1957-04-11
Abstract: Dosage unit forms of hexylresorcinol are prepared by mixing hexylresorcinol and a silica aerogel to obtain a free-flowing powder which is incorporated in a gelatin capsule.  The mixing may be achieved by (1) heating the hexylresorcinol; (2) dissolving the hexylresorcinol in a solvent such as olive, corn, cottonseed or castor oil, or polyethylene or polypropylene glycol; (3) dissolving the hexylresorcinol in a volatile solvent such as ethyl alcohol, acetone, benzene, chloroform, or carbon tetrachloride with subsequent evaporation assisted by heat if necessary, and adding a silica aerogel to obtain a free-flowing powder.  Diluents such as dicalcium phosphate and starch, and lubricants, such as magnesium stearate, may be added.  The mixture should contain 5 to 50 per cent by weight of hexylresorcinol. Specification 674,172, [Group V], is referred to.

Title: Mobile railway track levelling machine
Inventor: PLASSER FRANZ
IPC: E01B29/04
Filed: 1969-03-07
Abstract: 1, 249, 905. Photo-electric control of railway track levelling apparatus. F. PLASSER. March 7, 1969 [March 7, 1968], No. 12132/ 69. Heading G1A. Mobile railway track levelling apparatus is provided with means for establishing a horizontal reference line extending along the track, comprising a radiation source 11 located on a lead truck 10, and two detectors 14', 14" mounted on the track packing and levelling unit 1 which is already on levelled track. Also provided are two shadow boards 12', 12<11> mounted to the track height adjustment means 5, and shaped and arranged such that on adjustment of the height of the track, the upper edge of one shadow board 12' changes the intensity of radiation reaching the detector 14<1> and the lower edge of the other board 12<11> changes the intensity reaching the other detector 14" . In the arrangement shown in Fig. 3, only one arrangement as described above is used for one rail 6 of the track, the height of the other rail 6' being connected by means of a cross-level indicator 17 e. g. a pendulum, spirit level or gyroscope. The arrangement of Fig. 3 also shows two fixed shadow boards 15<1>, 15" which permanently shield upper and lower halves of detectors 14', 14<11>. Thus, when the track is at the correct level the detectors are obscured by the combinations of boards 12<1>, 15<1> and 12<11>, 15<11>. At levels above and below the correct one, either one of detectors 14', 14<11> will receive light and its output signal is used to control the hydraulic jack 5 to raise or lower the rail 6. The fixed shadow boards 15 may be omitted, Figs. 4-6 (not shown) in which case the differential output of the detectors is used to control the height adjustment jack(s). For example, each detector output may control the pressure to one side of the jack. At the correct track height the pressures are equalized; at any other the difference in pressure causes lifting or lowering. This method of control ensures that excessive raising or lowering does not occur, since with decreasing pressure difference the jack operation slows down. The radiation source may emit infrared or visible radiation and be pulsed. The shadow boards may be integral or separate and mounted on separate arms. Each rail may be operated under the control of its own photo-electric-shadow board system. A single source may supply all four detectors in the latter case.

Title: Control means to control machining of workpieces on lathes or the  like

Filed: 1972-03-15
Abstract: 1380362 Automatic control of machining GILDERMEISTER AG 15 March 1972 [16 March 1971] 12152/72 HeadingG3N A program control system stores a desired final contour for a workpiece being machined. The load on the machine tool is measured and compared with a nominal value, the difference being used to control the relative longitudinal and transverse tool feed rates, while maintaining the magnitude of the feed vector at a predetermined value. In the system shown, the spindle 5 of a lathe has a chuck 17 holding a workpiece 6 for machining by a tool 7 controlled by a slide 8 with a longitudinal (Z) drive motor 15 and transverse (X) drive motor 16. Signals from a torque measuring device I and a rotational speed device 3 are fed to a multiplier 4 and their product is supplied to control circuits 10, 11 which compare the input product with a set value and use the result of the comparison to adjust the relative energization of the feed motors 15, 16 through a switching arrangement 14 which can reverse or exchange the control signals in accordance with the machining quadrant. The circuits 10, 11 have sinusoidal or linear characteristics in relative quadrature so that the feed vector is rotated according to the measured speed and torque values but its magnitude is substantially unaltered at a value set by an input circuit 12. The tool may be pivoted to maintain it in the most effective machining position relative to the feed direction. Geometrical correction factors may also be supplied by an input stage 13. In operation, the cutting cycle is repeated until a stored contour is achieved, comparison between actual and desired contour being made during the machining operation. An accelerated feedrate may be employed in areas where the final contour has been previously reached. Generally the system operates in a manner which maintains the chip thickness approximately constant.

Teeth 31 on the outer races 15 of the ratchet clutches 14 mesh with teeth 30 on the outer race 28 of the ratchet clutch 29 the inner race of which is formed by the input shaft 6. The gear sizes being such that the engine braking is greater than it would be through the highest ratio. The outer race 15 is fast with a shaft 16 carrying gears 19, 20 in permanent mesh with gears 21, 22 freely rotatable on an output shaft 7 and selectively clutched thereto at 25. In Fig. 2 the ratchet clutch 29 is in parallel with a positive clutch 32, 33<SP>1</SP> which is normally held disengaged by cam projections 37 on the eccentric 8 engaging the end of the clutch member 33.

On reducing the eccentricity of the disc 8 the cams on the projections 37 disengage the clutch.
