Title: Process for making fibrous material water-repellant
IPC: D06M15/37
Filed: 1961-02-20
Abstract: Polyamines having lipophilic residues, e.g. those described below, are reacted with epichlorhydrin.  (1) 1 mol. of the methyl ester of hardened cottonseed oil fatty acids and 1 mol. of dipropylenetriamine were reacted together, and 400 parts by weight of the product melted in a stirred vessel under reflux.  A mixture of 120 parts of epichlorhydrin and 100 parts of denatured ethanol was added and stirred at 80-90 DEG C. and then diluted with water. (2) 130 parts of saturated alcohol obtained by the hydrogenation of tallow fatty acids were melted in a stirred vessel under reflux, and 1 part of tin tetrachloride and 46.5 parts of epichlorhydrin added at 70 DEG C. The mixture was stirred at this temperature for 30 minutes, and then 33 parts of dipropylenetriamine and 44 parts of 50% caustic soda were added, and the mixture stirred for 45 minutes while heating to 120 DEG C. The product was washed with water, and, after the addition of 100 parts denatured ethanol, reacted at 80 DEG C. with epichlorhydrin and then diluted with water.  (3) 130.5 parts of commercial hexadecyl chloride were stirred with 66 parts dipropyl triamine, 51 parts of 50% soda lye, and 60 parts of 96% denatured alcohol, and boiled under reflux.  The sodium chloride formed was filtered off, and the filtrate reacted at 80 DEG C. with 93 parts of epichlorhydrin and then diluted with water.  (4) 300 parts of N-hexadecylpropylenediamine were treated with 100 parts of 96% denatured ethanol in a stirred vessel.  140 parts of epichlorhydrin were added at 70 DEG C. with stirring, and the mixture boiled under reflux, and then diluted with water.  (5) 270 parts of N-dodecyl-p-cyclohexylenediamine were stirred with 80 parts of 96% ethanol, and 140 parts of epichlorhydrin added at 75 DEG C.  The reaction mixture was boiled under reflux, and then diluted with water.  The products may be used for waterproofing (see Group VIII).

Title: Improvements in electrically ignited rockets, flares and the like
IPC: F42B12/68
Filed: 1947-03-04
Abstract: 622,030. Pyrotechnic apparatus. SCHERMULY, C. D., SCHERMULY, A. J., and SCHERMULY, C. March 4, 1947, No. 6096. [Class 9 (ii)] A device comprising a rocket or flare is housed in an outer casing 1 having electrical ignition means in its rear end embedded in an expelling charge and electrical contacts on its outer wall and base connected to the ignition means. The millboard casing 1 is closed at its forward end by a wooden cap 2 and at the rear by a wooden plug 3 accommodating an explosive charge 5 in which are ignition wires 7 having leads 8, 9 passing through passages 10 to a recess 11. The leads 8 are soldered to a brass strip 14 on the casing 1 and the leads 9 are soldered to a dished metal plate 15. The recess 11 may be filled with clay or like non- conducting material. Within the casing 1 is a casing 16 closed by a wooden cap 17 and a wooden plug 18 containing a powder charge 19. A pressed delay action fuze 21 fills an axial bore in the plug 18 which is spaced from the plug 3 by an annular felt pad 22. A primed cambric 23 secured to a flare candle 24 contacts the flare composition 25. The flare candle is closed by a metal cap 26 to which is secured the cords of a parachute 30. The flare is fired from a discharger described in Specification 622,029, the brass strip 14 contacting the barrel of the discharger and the plate 15 contacting the brass contact insulated within the barrel to complete the electric circuit. On closing the firing switch the explosive charge 5 is ignited and ejects the casing 16, the flash from the charge 5 having ignited the delay fuze 21 which ignites the charge 19 to eject the flare candle 24 from the casing 16. The flash from the charge 19 ignites the cambric 23 and hence the flare composition 25. The inner casing 16 may be replaced by a rocket.

Title: Harvesting and/or processing machine for agricultural products
IPC: A01D41/127
Filed: 1972-02-09
Abstract: 1378715 Combine harvesters MASCHINENFABRIK FAHR AG 9 Feb 1972 [13 Feb 1971] 6101/72 Heading A1F [Also in Divisions G1 and G3] A harvesting machine or any processing machine for agricultural products which involves jobs such as separating, grading or classifying, and in which the processing speed has to be chosen to provide an optimum return between the opposing requirements of rate of processing and quality of output, comprises means for measuring a loss value, or loss values, such as the volume, weight, or number of damaged items, or of wrongly transported items (e.g. grain in the straw discharge of a combine harvester), means for measuring another value, which is the volume weight or number of correctly transported material, on the overall harvested or processed material, and comparison means for relating the loss values to the other value; the comparison means includes an indicator device for indicating the comparison result and/or a regulating device for regulating the machine according to the comparison result. In particular in a combine harvester the other value may be either the quantity of harvested grain or the area of field harvested. The former may be measured by electrical transducers such as capacitative or photoelectric detectors or balances to measure degree of filling, or acousto-electric or capacitative or photo-electric transducers to measure flow rates, which may also be measured, but less accurately, by turbines or bucket wheels. The area harvested may be measured by path or travel speed transmitters coupled to the ground wheels, together with a separate transmitter for the working width if this is not constant. The loss values may be measured by similar electrical transducers. In an araby method voltages proportional to the measured loss value and to the other value are produced, and supplied to a quotient former, whose output is either displayed to the operator, or use to provide automatic control for the machine. In a digital method signals in excess or short of a certain value are transmitted instead, and used to provide visible or audible warning to the operator that the losses have exceeded a predetermined limit. The measurement of one value, loss or otherwise, may be used to "trip" the measurement of the other. In the combine harvester shown discharge of grain from the straw shakers is measured by the capacitative passage 2 and similar passage 5 measures discharge of grain from the chaffer sieve 4. A third passage 6 measures the supply of threshed grain to the grain tank 7. The falling grains vary the capacity of the capacitors in the passages 2, 5, and 6 and these variations are transmitted via high-frequency measuring bridges 13, amplifiers 10 and rectifiers 11 as voltages. A voltage X 1  originating from passages 2 and 5 is supplied together with a voltage X 2  originating from passage 6 to a quotient former 9, whose output appears on an indicating device 12 in the operator's cab.

Title: Improvements relating to the production of rotagravure printing surfaces
Inventor: WILBY WILLIAM PETER LAWHAM
IPC: B41C1/05
Filed: 1963-02-15
Abstract: 1,035,342. Copying by scanning. CROSFIELD ELECTRONIC Ltd. Feb. 6, 1964 [Feb. 15, 1963], No. 6270/63. Heading H4F. A printing surface is produced on a metal cylinder 14 by evaporating the surface by means of the intense beam of a radiation from a laser 12 which is controlled by pulses which are modulated in respect of amplitude, repetition rate and/or duration by signals derived by the photo-electric scanning an original 4. The cylinder is subjected to rotational and axial displacement and its movement is utilized by a photo-electric system 16, 16a, 17, 18 to control the production of pulses by master generator 19 which serve to synchronize the scanning of the original 4 by cathode-ray tube 1. The pulses are also applied to control the laser through a circuit 9 which is controlled by the signals derived from the original. The apparatus is illustrated as applied to the production of a printing surface from one colour component of a multi-coloured picture, the signal for circuit 9 being obtained from a known form of correction computer 6 which receives signals obtained by scanning three colour separation transparencies of which only one, 4, is shown. The output of circuit 9 is applied to the laser by way of power transistor 10 and pulse transformer 11. To stabilize the laser beam energy a fraction of its output is extracted by a semi-reflecting (or partially-intercepting) mirror 23 and directed to a photo-electric cell 22 whose output is applied to circuit 9 as negative feedback. Reference is made to the use of a random pulse source to control circuit 9 and variation in pulse rate to correspond with the degree of detail and tone to be printed. The laser may be of the gallium arsenide or ruby type. The signals representing the original may be obtained from a magnetic tape or other storage medium.

Filed: 1959-02-24
Abstract: 885,699. Securing articles on shafts. SVENSKA KULLAGERFABRIKEN A.B. Feb. 24, 1959, No. 6305/59. Class 80 (2). [Also in Group XXII] A press-fitting joint between a pair of joint members having inner and outer opposed surfaces of rotation respectively is characterized by the provision of a pressure member arranged to be forced into pressure relationship with a single or a stepped conical surface concentric with the press-fitting surfaces of the said joint members, in which said pressure member contacts the said conical surface at or near each end thereof through a comparatively narrow continuous annular portion or sealing surface and further characterized by the provision of one or more sealed chambers between the opposed surfaces containing a pressure medium having low internal friction such as a liquid, grease, soft paste or a semi-liquid substance. In an embodiment a hub 1 having an external conical surface 2 is mounted on a shaft 3 by means of a compression sleeve 4 having a cavity 5 bounded by annular sealing ribs 6 and 7 which engage the conical surface. The cavity is filled with a mixture of oil or grease with a mineral substance such as sodium. The sleeve is first forced so far on to the conical surface of the hub that there is no leakage of oil or grease and then locked in this position by a ring 8. After the hub has been mounted on the cylindrical or conical surface of the shaft 3 the sleeve is forced further up the conical surface and the locking ring is transferred to another groove 27. In a modification the sleeve is thicker at its ends and central portion and two cavities 23 and 24 are provided. Screws 25 assist the dismounting of the sleeve. In another embodiment the sleeve is forced into place by a nut 12 and rubber sealing rings 16 and 17 ensure a fluid-tight seal for the cavity 5. In a further embodiment the conical surface of the hub is stepped (Fig. 5) and the sleeve is forced into position by a hooked bolt 40. If the hub is made of a permeable material, such as cast iron, a thin sleeve having a tapered surface is first mounted on the hub and the compression sleeve is mounted on the thin sleeve. In another embodiment the hub 28 of a coupling is mounted on the hollow end of a shaft 29, an internally tapered sleeve 30 is mounted in the shaft and the joint is effected by a tapered plug 32 provided with sealing ribs 33 and 34 leaving a cavity 35 for the pressure medium. The plug is forced into the sleeve by a screw 36. The pressure medium may be oil, grease, oil mixed with colloidal clay or graphite or a mixture of a liquid and a mineral or a mineral soap mixed with an organic fat to form a pasty or viscous substance. The depth of the cavity is between 0.2 and 0.02 mm.

Title: Improvements in or relating to coin freed mechanism for turnstiles and the like
IPC: G07F17/14
Filed: 1936-03-03
Abstract: 471,329. Coin - freed turnstiles. ELLISON & CO., Ltd., W. T., and DELUCE, S. E. March 3, 1936, No. 6359. [Class 27] In a coin-freed turnstile in which the locking mechanism is released by a coin forming a thrust transmitting connection between two axially aligned plungers, one of which is manually operated, in order that the mechanism will function when a plurality of coins are inserted, the coin passage i<1>, Figs. 3 and 4, is provided with a byepass to receive and retain all but the final coin which is deflected by the last but one coin to its operative position. As shown, the mechanism is set to require five coins to unlock the turnstile. The first four coins j<1>, j<2>, j<3>, j<4> are received in the byepass, the first coin j<4> resting on a stop bar k and the last j<1> deflecting the final coin to its operative position between the plungers. The stop bar k is carried by a member l moving with the actuated plunger, so that when the turnstile is unlocked and operated, the bar k is withdrawn from the passage il and the coins fall to a money-box. The bar k is detachably secured by a pin l<6> in one or other of transverse tubes l<1> . . . <l5> in the member l so that the apparatus may be set to take different numbers of coins. When the proper number of coins have been inserted, the cranked end of a lever p pivoted to the fixed casing and connected at p<1> to the member l or actuated plunger is moved into the passage i by the movement of the actuated plunger. This lever and an inclined extension d<1> on the manually-operated plunger retains a further coin until the turnstile has been operated and the plungers restored to their initial position, whereupon the retained coin can enter the byepass. The passage i<1> is formed with projections r on the side walls so that the coins take a slightly zigzag course, causing small coins to escape through openings s. When the bar k is in the tube l<1>, the mechanism will function when a single coin has been inserted.

Abstract: 432,228. Variable - speed gearing. TURNER, W., 17, Peel Grove, Longsight, Manchester. Feb. 9, 1935, No. 6416/34. [Class 80 (ii)] Planetary frictionrollers g are splined on radial spindles d, carried by a driving cage c, and rotated by toothed engagement with a stationary bevel wheel f on a fixed shaft b, the rollers being movable, centrifugally and/or manually, over the face of a driven bevel disc j. Final drive to a toothed wheel n is through a planetary reducing train, comprising a fixed sun-wheel f<2>, formed on the bevel wheel f, an annulus j<1> formed in the driven disc j, and a planet-carrier m<1> secured to the toothed wheel n, which drives, say, the cardan shaft of a motor vehicle. Neutral and reverse may be within the range of adjustment or independent reversing-gear may be provided. The disc is pressed axially towards the rollers by a spring k<4>, and in the top-speed solid-drive position engages directly with the outer part of the driving-cage c, the rollers being then out of contact with the disc. Speed variation may be automatic in accordance with centrifugal force acting on the friction rollers g, which are drawn inwardly by tension springs i. Manual adjustment is also possible by turning a loose plate h, having cam-slots h<2>, engaged by roller-supporting members g<3>, which also pass through radial slots in the cage c. The cam-plate h is turned by axial movement of a control-collar q, feathered to the driving shaft a, and having an inclined key- and-slot connection with the cam-plate. A control-lever may be connected to the collar q with sufficient play as to allow automatic movement of the cam-plate h, throughout the centrifugal range of the rollers g, without affecting the lever. The gear may constitute its own clutch, controlled by a pedal, acting through a fork p to retract the disc j.

Filed: 1935-03-04
Abstract: 453,231. Portable crop-sprinklers. BURNSIDE, C. F. M., Mill Cottage, North Lancing. Sussex. March 4, 1935, No. 6753. [Class 47 (ii)] [See also Groups XXVIII, XXIV, and XXVI] A portable pumping set for agricultural use comprises a 1.p. pump for watering and a h.p. pump for spraying, which are used alternatively. The pumps are driven by an electric motor, or by an internal-combustion engine 1. The plant is mounted on a barrow, comprising side members 9, extended to form handles 13, and united by a tray 3, which may form an exhaust silencer, and by the axle 10 of a wheel 32. The l.p. pump 4 is preferably rotary and is directly coupled to the engine, while the h.p. pump 8, preferably a gear pump, is driven from the spindle 6 of the l.p. pump through a detachable coupling 7. When the h.p. pump is in use the l.p. pump runs idly, while, when the l.p. pump is in use the h.p. pump is disconnected. Water is supplied to the cooling jacket of the engine by pipes 18, 19 from the discharge 16 and inlet 14 of the l.p. pump when that pump is in use. When the h.p. pump is in use the pipes 18, 19 are closed by cocks 36, 37 and pipes 20, 21, leading to the discharge and inlet of the h.p. pump, are opened by means of cocks 34, 35. An adjustable spring-pressed valve 33 in the pipe 20 regulates the amount of the h.p. discharge which passes to the engine jacket.
