Title: A hydraulically-operated multiple clutch change speed gear
IPC: F16D25/10
Filed: 1937-02-08
Abstract: 482,632. Variable - speed gearing ; friction clutches. KEGRESSE, A. Feb. 8, 1937, No. 3735. Convention date, Feb. 10, 1936. [Class 80 (ii)] In a three-speed gear comprising three hydraulically-operated friction clutches A, B and C adapted to transmit respectively low, intermediate and high speed drives from a driving flywheel 54 to nested gear-carrying shafts 44, 45 and 46, each clutch comprises a driven disc. such as 41, secured to the corresponding shaft 44 and arranged between a pair of discs 59 and 59<1> splined in the flywheel, the discs 59 and 59<1> being moved towards each other so as to grip the disc 41, against the action of retracting springs 62, by diaphragms 18 and 22 which bear against the discs 59 and 591 and which are secured over annular recesses formed in plates 57 and 58 fixed in the flywheel. Pressure fluid is supplied through passages 63 and 34 to a chamber 35 in the end plate 56 of the flywheel, and thence past a pressureresponsive spring-loaded valve 36 to a duct 66 leading to the annular recesses of the lowspeed clutch A. From these recesses, a duct 67 leads to a chamber 68 above a similar valve 69 controlling the supply through a port 70 and duct 71 to the annular recesses of the clutch B. From the latter, a duct 72 leads to a chamber 73 above another similar valve controlling the supply through a port 74 to the clutch C. The valves are mounted in members 77 detachably fitted in the periphery of the plate 56. The spring loading of the valve associated with a lower speed clutch is smaller than that of the valve associated with a higherspeed clutch, so that the clutches operate in succession as the oil pressure varies. As a valve closes, the annular recesses of the associated clutch are vented through ports 76. Each metal diaphragm is, in the disengaged condition of the clutch, flexed by the action of the retracting springs into the corresponding recess, and, when the clutch discs are new, the' application of fluid pressure restores it to its natural plane condition. As the discs wear, however, the diaphragm flexes beyond this plane condition. The Specification as open to inspection under Sect. 91 comprises also a single clutch, constructed as above, between a driven shaft and a drum secured to a driving shaft, wherein a valve movable axially in the driving shaft is adapted to put the passage 34 into communication either with a supply of pressure fluid or with a vent port. There may be more than one disc secured to the driven shaft, each such disc being arranged between a pair of oppositely-movable driving discs. This subjectmatter does not appear in the Specification as accepted.

Title: New or improved apparatus for washing out the interiors of receptacles such as petrol or other oil cans
IPC: B08B9/08
Filed: 1921-02-01
Abstract: 179,280. Hayes, A. H. Feb. 1, 1921. Cans, washing and cleaning.-The interiors of receptacles such as petrol or other oil cans are washed out by a device comprising or tank or container for the washing-fluid, from which the washing-fluid, such as petrol, is supplied to a rotatable jet pipe by a pump, wherein the operation of the pump imparts a rotary movement to the jet pipe about its axis, and a relatively reciprocal movement between the receptacle and the jet pipe. In the arrangement shown in Fig. 1, the tank 1 is divided by a partition 4 so that the washing-fluid which is forced by the pump 6 into the can 17 is first freed from foreign matter. The liquid enters the piston cylinder through a non-return valve 9 on the up-stroke of the piston 7, and is forced on the return movement of the piston through a pipe 12 and a hollow jet pipe 10. The member 10 is formed with an external thread 13 engaging a nut 15 fixed to the ram-rods 16 of the pump, whereby it is rotated as the pump is operated so as to discharge the washing-fluid with a whirling motion into the petrol can 17. By forming the orifice 18 as a narrow slit the washing-fluid is ejected in the form of a thin sheet. The pump is reciprocated by a lever 19, pivoted at 20, and attached bv links 25 to the cross-bar 27 of the rods 16. The pump lever is operated by a handle 24 and a pedal 22. The used washing-fluid is discharged by a return pipe 29 into the compartment 2 of the tank. The support 28 for the can is supported on the cross-bar 27 so as to have the same movements as the pump piston. In a modified construction, the jet pipe 10 is rotatably connected with the ram piston, and in such a manner that, in addition to a reciprocating movement, it has a rotary movement by engagement with a tubular member of the pump barrel as the pump is operated. The return pipe 29 is rigidly secured to the top of the tank 1, the supporting-member 28 being fixedly mounted.

Title: Improvements in or relating to a rock-to-sleep doll eye
IPC: A63H3/40
Filed: 1966-01-27
Abstract: 1,067,105. Doll's eyes. AMERICAN CHARACTER, Inc. Jan. 27, 1966 [April 7, 1965], No. 3820/66. Heading A6S. A rock-to-sleep doll's eye comprises a pivoted eye member E pivoted about a horizontal axis a and having a weight member W pivoted thereon about a vertical axis b and a ratchet member R on said weight member W having staggered stepped teeth 48, 50 engagable alternately with a pair of fixed pawls P. When the doll is first laid down the eye remains open owing to the lefthand pawl, as viewed in Fig. 4, engaging the upper tooth of the lefthand teeth 48 of the ratchet member R. Rocking the doll causes the ratchet member R to swing the upper tooth clear of the lefthand pawl P, whereupon the next tooth 50 down on the righthand side of member R engages the righthand pawl P. Continual rocking causes a step-by-step movement of the ratchet member R to left and right until the eye finally closes. The eye immediately returns to the initial position under the influence of the weight member W when the doll is restored to an upright position, the ratchet member then making a rapid succession of left and right movements until such initial position is reached.

Abstract: 724,550. Boring-heads. WALDES KOH-INOOR, Inc. Feb. 11, 1953, No. 3829/53. Class 83 (3). An adapter for use with a grooving tool 10 comprises a body 16, 18, 19, means 17 for mounting the body adjustably on the spindle 12 of the tool so that it rotates with the spindle, and a bottom plate 22 rotatable relatively to the body so that the plate may be kept stationary while the body rotates with the spindle as a groove 27 is cut in the bore 25 of work 24. The plate 22 is held stationary through contact with a shoulder 26 in the bore, and a bearing 23 is provided between the plate and the body. If the slot is to be located relatively to the bottom wall of the bore instead of to the shoulder 26, the body is replaced by one not having an extension 20 below the plate 22. The adapter and tool assembly is inserted in the bore 25 with the cutter, 14, which is mounted on the end of a shaft 13 supported in an eccentric bore in the spindle 12, retracted from the cutting position shown in Fig. 3. Upon applying pressure to the shaft 11 of the tool, which is rotated by a lathe or drilling machine, after the plate 22 has engaged the shoulder 26, a follower (not shown) on the shaft 13 is influenced by the downward movement of a cam slot to rotate the shaft about its own axis and bring the cutter 14 into the cutting position, an adjustable stop (not shown) limiting movement of the part in which the cam slot is. formed. The body may be formed as an integral construction, and its part 19 need not extend around half of the crosssection.

Patent GB-1011994-A (GB)
Title: A process for preparing 5-ribonucleotides
IPC: C07H1/02
Filed: 1963-01-30
Abstract: A 51-ribonucleotide is obtained by dissolving the corresponding 21,31-O-protected ribonucleoside in phosphoryl chloride while maintaining the reaction mixture at from 0 DEG  to 30 DEG  C. to produce the 2,31-O-protected ribonucleoside phosphorodichloridate, hydrolysing the latter to convert the phosphorodichloridate group to phosphate, then hydrolysing the 21,31-O-protected -551-ribonucleotide to remove the O-protecting group and recovering the desired 51-ribonucleotide or an alkali metal salt therof. Advantageously an amount of water, partially hydrated phosphoryl chloride, an ether, an aliphatic alcohol containing from 1 to 5 carbon atoms, or phosphoryl chloride in which the chlorine is partially replaced by an aliphatic alcohol radical containing from 1 to 5 carbon atoms is added to the solution of ribonucleoside in phosphoryl chloride.  The nucleoside may be protected by acetal, diacyl, or cyclic carbonate groups, preferably by a 21,31-O-alkylidene group.  A small amount of a metal halide, e.g. ferric chloride, may also be added to the reaction system.  Specified alcohols which may be present are methanol, tert.-butanol and isoamyl alcohol and a molar ratio of alcohol to nucleoside of from 1 to 5 is suitable in the case of inosine.  The amount of water present should generally not exceed 1 mole per 20 moles of phosphoryl chloride.  Specified ethers are ethyl ether, isopropyl ether, dioxane, methyl ethyl ether, methyl n-propyl ether, ethyl n-butyl ether, ethynyl ether and benzyl ethyl ether and the reaction may with advantage be carried out in the presence of both an aliphatic alcohol and an ether.  The hydrolysis of the protected ribonucleoside 51-phosphorodichloridate may be carried out by adding it to water, optionally with aqueous caustic alkali in which case the resulting solution is maintained at a pH from 6 to 8, and the removal of the protecting group may be effected by heating the protected nucleotide in aqueous medium of pH about 1.5 and at about 70 DEG  C. for 1 hour.  Unused phosphoryl chloride may be recovered before the hydrolysis steps by concentration in vacuo, solvent extraction (e.g. by ligroin or ether) or by freeze-drying.  Examples are given for the production of 51-sodium inosinate, 51-sodium guanylate and 51-sodium adenylate.

Abstract: 1,195,662. Arc welding control systems. ANGLO AMERICAN CORP. OF SOUTH AFRICA Ltd. 24 Jan., 1969 [24 Jan., 1968], No. 4058/69. Heading H2H. In order to protect the operator of an arc welding apparatus whilst replacing a welding electrode the voltage applied to the welding apparatus is reduced. Arc welding apparatus 16, 17 is supplied from an A.C. source 10 by way of a contactor 14, having normally open contacts 13 and normally closed contacts 26, and a transformer 12. Connected between the secondary winding 15 and the welding apparatus is a voltage sensing device 18 which comprises back-to-back diodes 19, 20 in parallel with a resistor 21. A second transformer 23 is connected to the A.C. source 10 and a secondary winding 24 of this transformer is connected to the primary winding 11 of transformer 12 by way of the normally closed contacts 26 of the contactor 14, the output voltage of the winding 24 being stabilized at a low value-say 5 volts. Whilst the electrode 16 is not in contact with the workpiece 17 no voltage is developed across the resistor 21, thus an amplifier 28 has no output and the contactor 14 is not energized. The welding apparatus is then supplied by winding 24 over closed contacts 26 at a low, safe, value. When the electrode 16 is brought into contact with the workpiece 17 a small current flows in resistor 21 developing a voltage which is below the breakdown value of the diodes 19, 20. This voltage is compared with a reference voltage 27 and applied to the amplifier 28. The consequent output of the amplifier energizes the contactor 14 by way of transistor 37 and the diode bridge 32 with the thyristor 31. The contactor 14 is then energized to close contacts 13 and open contacts 26 whereupon the welding apparatus is supplied with normal voltage from the source 10. When the electrode 16 is again moved out of contact with the workpiece 17 the system reverts to supply from the winding 24 after a time delay introduced by the discharge of a capacitor 30.

Apparatus for detecting the passage of ferrous objects, e.g., motor cars, on a road comprises a coil wound on the two limbs of a U-shaped core 1 (Fig. 1) located beneath the surface of the road 5, and consisting of an energizing winding 4 and a pick-up winding 3. The coil is mounted with the side limbs vertical, and elongated or flat pole pieces 2 are added parallel to the plane of the road 5. A number of detector units may be assembled under the surface with the energizing windings 14-17 (Fig. 7) connected in series, and the pick-up windings 18-21 connected to eliminate the effect of ripple in the supply to the energizing windings. The overall sensitivity may be made uniform by varying the spacing, the depth or sensitivity of each unit. Signals from unidirectional traffic may be selected by using two rows of detector units, the responding equipment being made to operate only when a signal is received from both rows in the proper sequence. The time interval between the signals may be used to determine the speed of a vehicle.

Filed: 1945-02-19
Abstract: 588,461. Electric indicating systems. NEWTON, E. P. (Standard Oil Co, of California). Feb. 19, 1945, No. 4172. [Class 40 (i)] A common indicator is actuated by detonation pick-ups associated with each of the cylinders of an internal-combustion engine. As shown in Fig. 1, the output from a number of detonation pick-up units 10-17 is applied to amplifier 35 through coupling condensers 19-26 and attenuator 29 which cuts out the low amplitude voltage signals due to combustion pressure and valve closure. The large amplitude voltages due to detonation are amplified and applied through tuned circuit 38, 39, tuned to the detonation frequency to a grid leak detector 45. The rectified signal is applied to gas discharge tube 48 causing it to fire, the tube normally being biassed to prevent conduction. Condenser 49, which is charged to the potential difference across resistor 50, discharges through tube 48 when it fires and thus keeps the tube lighted for a longer period. The conductor 27 connecting the pick-ups to the amplifier is shielded to avoid pick-up from the radio or ignition system, the capacitance of the shielded conductor being compensated for by loading-inductance 30.
