Title: Hydraulic transmission mechanism
IPC: B60K6/12
Filed: 1963-01-23
Abstract: 1,017,571. Hydrostatic transmission. F. A. SUMMERLIN. Jan. 22, 1964 [Jan. 23, 1963; March 4, 1963; March 18, 1963; May 16, 1963], Nos. 2934/63, 8572/63, 10682/63 and 19573/63. Headings F2C and F2D. An hydrostatic transmission for a motor vehicle in which the torque transmitted is automatically varied in response to the difference between input and output speeds comprises an engine-driven fixed displacement rating swash-plate pump 11 which delivers to a hydro-pneumatic accumulator 17 until the pump delivery pressure is equal to the pressure in a motor circuit 14, 15 whereafter the remainder of the pump delivery is supplied through a network 16 of non-return valves to a fixed displacement motor 13. Variation of output load varies the pressure in the circuit 14, 15 and thus the quantity of liquid supplied by the pump to the motor circuit per pump cycle. The motor circuit is provided with a reversing valve 18 and pressure relief valve 76. An engine-driven make-up pump 66 supplies pressure liquid to an accumulator 69 in the motor circuit. During starting, a valve 61 short-circuits the motor 13 until the engine speed reaches a predetermined value whereupon the pressure developed by the make-up pump 66 overcomes a spring to close the short-circuit valve 61. Alternately, the valve 61 may be operated by a centrifugal device. The hydro-pneumatic accumulator, Fig. 5, comprises a gas chamber 24 which separates two liquid chambers respectively connected to the two cylinders of the pump. During the suction stroke of the pump cavitation of the pump cylinders is prevented by drawing liquid from additional chambers 60 in the period before the non-return valves open. The pump 66 may also supply lubricant to the pump and motor bearings. The pump 11 may drive two motors connected in series or parallel each of which is connected to one of the vehicle wheels.

Title: Vibratory mill and method
IPC: B02C17/14
Filed: 1965-01-22
Abstract: 1,087,986. Vibratory grinding. U.S. STONEWARE Inc. Jan. 22, 1965 [Feb. 7, 1964], No. 2981/65. Heading B2A. A process of vibratory grinding in a substantially horizontal vessel containing tumbling grinding media as well as material to be ground comprises moving the respective ends of the vessel in looped eccentric paths, each in a substantially vertical plane, without rotating the vessel, the eccentricity of one end of the vessel leading that of the other end and thereby causing the grinding media to move in loop orbits within the vessel about a horizontal axis, making repeated contacts with one another and with the wall of the vessel, and by such motion of the vessel causing the grinding media to maintain a relatively constant position longitudinally with respect to the ends of the vessel while causing the material to be ground to travel towards one end of the vessel while being subjected to repeated grinding contacts with the grinding media. In a mill for carrying out the process, motor-driven shafts 8 and 9, Fig. 5, at the ends of a vessel 5, are mounted in eccentric cams 10 and 11 which rotate within housings 12 and 13, and the eccentric mountings are opposed by counterweights. The eccentric 10 leads the eccentric 11. The grinding media 20 moves in relatively circular orbits whereas the material, which is supplied at 30 and discharged at 31, follows a generally helical path. The vessel is resiliently supported. In a modification, driven shafts 50 and 51, Fig. 9, at the ends of a vessel 40 have eccentric weights 53 and 54 secured thereto, the eccentric 53 leading the eccentric 54. The vessel has a discharge opening 55.

Title: Improvements in impulse transmitters for use in telephone or like systems
IPC: H04M1/274
Filed: 1925-02-04
Abstract: 235,136. Automatic Telephone Manufacturing Co., Ltd., (Assignees of Blessing, J. G.). June 7, 1924, [Convention date]. Impulse transmitters.-A transmitter of the dial type used for numbers which are called very frequently is so constructed that only a single setting operation is required to set up the complete connection. The impulse cam 39 always generates the same number of impulses, and the variable setting of the dial 12 causes the selection of one of a number of cam discs 30 which cooperate with springs 60, 61 to split up the impulses into trains, one cam disc being provided for each subscriber. Two movable finger stops 11, 11<1> are provided on a bar 56, which always moves through the same angle (156) to prepare for the rotation of the impulse cam. Gear wheel 13 is fixed to the bar 56, and tensions the usual driving spring during the setting movement, shafts 58, 74 remaining at rest. When the finger stop moves from normal a pin 51 on the bar 56 releases an arm 50 on a shaft 97, so that the latter is rotated slightly by a spring to unlock shaft 58 by means of an arm 46, Fig. 7, and to bring a detent 47 into engagement with a ratchet 26 on the shaft 22 of the dial. When the dial has rotated through the angle of movement of the finger stop (156), the lowest point of an inclined wall on ratchet 26 engages a roller 34 on an arm 25, and the roller then rises on the inclined wall so that a bracket 44 with springs 60, 61, 80 is lifted by arm 25 opposite the appropriate cam disc 30. The setting operation is completed when a pin 43 or 43<1> on the bar 56 engages a stop 108 on the mounting plate 8. During the return movement of the bar 56, the shaft 58 of the impulse cam is rotated from gear wheel 13 through a ratchet 18, while the shaft 74 carrying the cam discs 30 is rotated through a ratchet 32 and pawl 33, so that trains of impulses are sent out under control of a governor 21 in a manner subsequently described. When pin 51 again strikes arm 50, shaft 97 returns to normal position, locking shaft 58 and removing detent 47, so that ratchet 26 and the dial return to normal under the action of a spiral spring 22, when a pin 15 engages projections on the finger stop 11<1>, while arm 25 and bracket 44 are restored by a spring 38. The impulse springs 66, 67, Fig. 4, are normally short-circuited by springs 60, 61, which are operated by cams 113, 114, 115 on the disc 30 to remove the short.-circuit and enable three trains of impulses to be sent out. The disc 30 makes a complete revolution at each operation. The engagement of a brush 59 with the cam disc shortcircuits the substation instruments while impulses are being sent out. The framework of the apparatus comprises mounting plates 7, 8 with posts 5, each having a cut-away portion and a screw 6. When the framework is placed in the tubular housing, the screws 6 are screwed outwardly into register with corresponding holes to lock the framework in position. Specification 4179/12 is referred to.

Title: Improvements in and relating to the manufacture of artifical filaments from viscose
IPC: C08G12/40
Filed: 1958-01-31
Abstract: 862,715. Spin dyeing viscose rayon; reaction products of aminoplasts and dyes. COURTAULDS Ltd. (Files de Calais). Jan. 30, 1959 [Jan. 31, 1958], No. 3248/58. Classes 2(2) and 2(5). In the production of coloured filaments or films from viscose there is added to the viscose before extrusion, the reaction product (prepared in the presence of an inorganic or organic base and substantially in the absence of water) of an aminoplast and a dye capable of combining chemically with cellulose, which reaction product is soluble in water or aqueous caustic soda solution. Suitable dyes are those containing a cyanuryl radical with at least one reactive chlorine atom. Aminoplasts are defined as mixtures of formaldehyde and an amino compound capable of reacting with formaldehyde to produce a resinous condensation product, such as urea, thiourea, melamine, ethylene urea or dicyandiamide, and all the condensation products of the mixtures which remain soluble in water or aqueous caustic soda of up to about 8% concentration after reaction in the presence of an inorganic or organic base with dyes capable of combining chemically with cellulose, and which form water insoluble products in the presence of acid, for example aqueous sulphuric acid such as is used in the extrusion of viscose, thereby ensuring precipitation of the reaction product simultaneously with the coagulation of the viscose. In an example, 60 gm. of urea is dissolved in 500 c.c. of water containing 2 gm. of caustic soda and 200 gm. of 30% formalin. The mixture is maintained at 35 ‹C. for 15 mins., kept for 48 hours at room temperature and the precipitate formed is filtered off. Then 4 gm. of the precipitate and 1 gm. of the dyestuff "Cibacron Blue 3G" are boiled for 1 hour in 40 c.c. of pyridine and the mixture is cooled, diluted with 200 c.c. of ether, and the precipitate filtered off. The aminoplast dyestuff reaction product thus formed is readily soluble in cold water and in viscose. In a second example, the same process is used with the dyestuff "Cibacron Scarlet 2G," and 6 gm. of the product obtained dissolved in 100 c.c. of water is mixed with 2 kgm. of viscose and the mixture is spun. In a third example 1 gram of "Procion Bright Orange HGRS," 2 gm. of urea and 2 gm. of paraformaldehyde are boiled for 1 hour in 40 c.c. of pyridine and the mixture is cooled, diluted with ether, and the precipitated reaction product filtered off. Specifications 501,603, 797,946 and 798,121 are referred to.
