Title: Machine for dispensing a band for sealing or wrapping an article
IPC: B65B51/06
Filed: 1966-01-26
Abstract: 1,115,572. Machine for dispensing tape. R. DE LA COUSSAYE. 26 Jan.; 1966 [27 Jan., 1965], No. 3414/66. Heading B8F. A machine for dispensing a band for sealing or wrapping an article (which band may be gummed) comprises (see the Figure):- a work surface 2 in which the operator pushes an article 3 to be wrapped in the direction of the arrow, the surface having an opening 4 through which the (gummed) band 5 is dispensed, a lever 6 pivoted at 7, a roll of paper 8, a guide slide 9, a movable knife 11 and fixed plate 12, a dispenser 17 for the tape pivoted at 18 and an upper roller 19 rotatable at 20 fixed to the end of lever 21 which pivots about axis 22. A lever 23 is pushed to the right by rod 24 pivoted at 25 on lever 6 and at 26 to a lever 27 which pivots at 28, the lever 26 being urged to the left by spring 34, one end of which is fixed to a member 35 fixed to plate 12. The engagement of rollers 17 and 19 is effected by lever 21. The dispensing action is effected by rotation of roll 17 in the direction of the arrow, Fig. 2, which is effected by rotation of pinion 29 in a counterclockwise direction, the pinion being driven by a chain 30 tensioned at one end by spring 31 fixed to a member at the front end of the casing, the other end of the chain being attached to point 33 of lever 6. Rotation of the pinion in a clockwise direction does not drive roller 17 since a free-wheel mechanism is provided. The knife 11 is activated by lever 6 which engages slide 53 able to release a catch 45, the return of the knife to the original position being effected by action of springs 47 and 48.

Abstract: 556,808. Quenching steel. AFRICAN SISAL & PRODUCE CO., Ltd., and BROWNE, R. J. March 16, 1942, No. 3434. [Class 72] [Also in Group V] Pectin or pectic substances are extracted from the flesh of plants of the Agave family, including Agave Sisalana by washing the flesh with water, preferably below 60‹C. to remove water soluble substances; treating the hesh with inorganic or organic acids preferably those having calcium salts of low solubility, and treating the whole mass of the residual flesh after filtration, with an alkali such as sodium or potassium carbonate or ammonium hydroxide. Pectic substances are precipitated from the filtered extract by addition of alcohol, acetone, chloride, sodium hypochlorite &c. or by addition of electrolytic acids, or metal hydrosols such as aluminium hydroxide. The acid extract, if separated before the alkali treatment may be treated with alcohol to precipitate pectin. If extraction is effected by oxalic acid in presence of ammonium oxalate, a product suitable for use in the quenching of steel is obtained. Specification 538,271 is referred to.

Abstract: 985,322. Clutch control. MITSUBISHI DENKI KABUSHIKI KAISHA. Jan. 30, 1962 [Jan. 30, 1961], No. 3485/62. Heading F2L. [Also in Division H3] An electromagnetic clutch is energized in accordance with the speed of rotation of its input shaft between predetermined limits. The clutch coil 10 is connected to the collector of a transistor 12 which has its base connected to the collector of a transistor 18. A generator 24 driven by the clutch input shaft is connected across a resistor 23 having a tapping leading, by way of a Zener diode 20 to the base of the transistor 18. At idle speeds the Zener breakdown voltage is not reached and the transistors do not conduct. When the speed is sufficient for the Zener diode to become conducting, both transistors also become conducting, and the clutch coil 10 is energized. As the speed of the input shaft increases the current through the clutch coil is increased until full clutch engagement is produced just prior to the transistor 12 reaching saturation.

Title: Apparatus for the fractional distillation of multi-component liquid mixtures
IPC: B01D3/30
Filed: 1952-02-14
Abstract: <PICT:0710158/III/1> Apparatus for the fractional distillation of multi-component liquid mixtures comprises an externally-heated cylindrical tube disposed in a vertical or inclined position, an inlet for introducing the liquid onto the inner surface of the tube, a blade-bearing rotor passing axially through the tube by means of which the liquid is spread as a film on the inner surface of the tube, partitions which rotate with the rotor and extend to the liquid film so that the partitions divide the tube in an axial direction into two or more chambers, and outlets for withdrawing vapours from the individual chambers to separate condensers.  The apparatus is suitable for the fractionation of temperature-sensitive mixtures under reduced pressure.  Liquid is fed through pipe A into externally-heated cylinder B, and is spread over the inner surface of the cylinder by blades C or rotor D.  The inner space of the cylinder is subdivided into four chambers by three circular discs F lying perpendicular to the axis and rotating with the blades, or by sectors arranged between the blades.  The vapours formed in the individual chambers are withdrawn from the top and base of the jacketed cylinder and through two openings G in the side, into four separate condensers J, which are maintained at the same pressure by vacuum pump K. High-boiling liquid withdrawn from the base of the heated cylinder is spun by blades C into channel O.

Title: Improvements in or relating to range finding surveying instruments
IPC: G01C15/00
Filed: 1949-02-15
Abstract: 664,760. Position finders; surveying instruments. SVENSKA AKTIEBOLAGET GASACCUMULATOR. Feb. 15, 1949 [Feb. 23, 1948], No. 4121/49. Classes 97 (i) and 97 (ii). A surveying instrument wherein a rangefinder and a plotting device are coupled for rotation about a common vertical axis for sighting on an object and are also operated by mechanism whereby movement of a plotting point radially of said axis is effected simultaneously with and in proportion to adjustment of the range-finder is characterized in that the mechanism for operating the range-finder is coupled to the mechanism for adjusting the plotting point by a coupling member which, when rotated about said axis, is adapted to effect radial movement of said plotting point. The instrument shown comprises a distant base range-finder consisting of two telescopes 3, 4 coupled by a sleeve 12 with a plating device K, the sleeve 12 being rotatable about a vertical axis in bearings H supported by a member S. The plotting device K comprises a plotting point 8 carried by a ruler 7, which is attached to the lower end 10 of sleeve 12. and supports a rack 6, which meshes with a pinion 18 on a shaft 16, coaxial with the sleeve 12 and engaged at 19, 20 with a rod 21 which is manually operable at 1. Rotation of rod 21 causes vertical displacement of a slider S<SP>1</SP> along a threaded rod 5 geared to the shaft, and this slider causes rocking of a rod 24 and consequent elevation of the telescope 4. In use, the range-finder housing 13 is rotated to bring the desired object into view, such rotation causing rotation of ruler 7. Thereafter, shaft 21 is rotated until the telescope 4 is sighted on a mask at a known height above the axis of telescope 3, rotation of this shaft causing proportional radial displacement of the plotting point 8. The latter can thus indicate on a chart the position of the object sighted relative to a fixed point 14.
