Title: Improvements in transformers with regulable output current
IPC: H01F29/10
Filed: 1946-01-30
Abstract: 607,269. Transformers; supply systems for welding arcs. UNITOR AKTIESELSKAPET. Jan. 30, 1946, No. 2964. Convention date, Jan. 30, 1945. [Classes 38 (ii) and 38 (iv)] A variable transformer having one or more magnetic shunts 5, 6 includes two or more secondary windings 3, 4, of which the winding 3 is on an iron path of regulable magnetic reluctance and winding 4 is on an iron path of constant reluctance; the secondary windings can be brought into operation individually or in parallel. The reluctance can be varied by moving the shunt 5-the motion being outwards, away from primary winding 2, to increase the current output. Shunt 6 is fixed. The maximum current output of winding 3 is preferably equal to the output of winding 4. A switch 7 is movable step-by-step to connect winding 3 in circuit alone or in parallel with winding 4 and to vary the effective numbers of turns in the windings. The load supplied may be an arc welding circuit 8.

Abstract: 1,170,965. Luminescent materials. AMERICAN CYANAMID CO. 19 Jan., 1967 [9 Feb., 1966], No. 2971/67. Heading C4S. [Also in Division G4] A record such as a cheque or card has symbols, e.g. legible characters, recorded thereon by means of a combination of at least one material which fluoresces under ultraviolet radiation and at least one material reflecting any or none of the visible colours red, green and blue. The symbols may be sensed by spatially separating the fluoresecent and visible portions of a symbol and simultaneously irradiating the respective portions with ultraviolet and white light, there being an appropriate number of photodetectors responding to the various fluorescent and reflected colours. Alternatively, the two symbol portions may overlap, and the symbol is sequentially illuminated with ultraviolet and white light. In this case, it may be possible to use the same detectors for both portions, the threshold level for sensing visible marks being higher than that for sensing fluorescent marks. The illumination sources may be covered by shutters as the record is intermittently advanced between successive symbols. The fluorescent materials may be 4,5-diphenylimidazolone-2 and lanthanide ion chelates, e.g. chelates of europium, terbium and samarium. Optical fibre light guides may be provided to the photodetectors.

Title: Single-die double-stroke header
IPC: B21K1/58
Filed: 1962-01-26
Abstract: 987,700. Extruding; forging. TEXTRON Inc. Jan. 26, 1962 [Jan. 27, 1961], No. 3022/62. Headings B3H and B3P. Tubular articles such as hollow rivets are mad in a two blow heading machine having an axially movable die 14 which is held positively in a forward position during the first heading blow. The horizontal header slide 45, Fig. 1, driven by crank-shaft 47, has a vertically slidable carrier 50 for a pair of heading punches 51, 52 which act successively on the workpiece in the die 14. Carrier 50 is actuated by linkage 55, 57, 60, roller followers 61 and cam 62 on half-speed shaft 63 driven through gearing 64, 65 from the crank-shaft. Die 14 is slidable axially in a holder 13 against springs 39 but can be held positively in a forward position, Fig. 4 (not shown), by an oscillating member 27, Fig. 2, driven through linkage 113, 115, 118 from the lever 57. The die contains a piercing punch 67 whose position is adjustable by screw 74. In operation wire stock is fed through a tube 110, Fig. 2, against an adjustable stop 111, severed by a cutter 112 and transferred in front of the single die 14. Punch 51 forces the workpiece into die 14, which is then held forwardly, and against piercing pin 67. A preliminary coneshaped head 53c, Fig. 4 (not shown), is thus formed and the other end is slightly pierced. On the next heading stroke the die 14 has been released and the second punch 52 thus presses the workpiece over the then stationary pin 67 to extrude it into a hollow shank and simultaneously the head is completed, Fig. 5 (not shown). As the header slide 45 retracts, the pin 67 is moved forwardly by linkage 69, 70, 78, 82, Fig. 2, lever 83, Fig. 1, and cam 86 to eject the workpiece, Fig. 6 (not shown). The ejected workpiece is gripped by spring-loaded finger 90 on lever 87, Fig. 9, and transferred adjacent a stopmember 125 where a blast of air from orifice 124 discharges it into a delivery shoot. The piercing pin 67 is retracted by a lever 105, Fig. 1, loaded by spring 109.

Filed: 1976-01-27
Abstract: 1509333 Sonars RAYTHEON CO 27 Jan 1976 [3 Feb 1975] 03032/76 Heading G1G A sonar for a ship has a transducer system 24 in which the receiving beam sensitivity direction relative to a symmetry axis 2 may be controlled. The beam direction may be space stabilized by making the beam control responsive to the ship's gyro. As claimed, a directional receiving or radiating system having a beam direction specified by bearing # and tilt α angle relative to an axis Z of the system comprises a plurality of rings (Nos. 1-8) of transducers 38 disposed in a corresponding plurality of parallel planes spaced along and perpendicular to the axis, variable delay devices (73), Fig. 8 (not shown), in channels individual to the transducers, and control means (58), Figs. 12 and 14 (not shown), responsive to selected tilt α and bearing # angles as to control the variable delay devices as to establish the beam direction, wherein the control means includes a store of sets of delay values, each set determining relative delays for transducers for an associated tilt angle, regardless of bearing angle, and selector means responsive to the selected bearing angle to associate the set of delays selected in accordance with the selected tilt angle with those transducers which provide a beam direction with the selected bearing angle. In the preferred embodiment, sets of twelve circumferentially sequential transducers from each ring, aligned parallel to the Z axis, are used to form the beam in reception. In transmission all the transducers are utilized, only the tilt α being controlled. Synchronization of transmission reference signals and reception allows gating to examine signals received from a specified range, azimuth and elevation and also allows the use of correlation techniques for the reception of echo ranging signals. The system may be used for passive listening. The transducer array may be disposed on a truncated hemisphere, Fig. 5 (not shown). The system may be alternatively an electromagnetic radiation system.

Abstract: 1,187,971. Foil press marking machine. J. H. ELLIS. 24 April, 1967 [24 Jan., 1966], No. 3176/66. Heading B6J. General arrangement.-A foil press marking machine comprises die supporting means 101, Fig. 3, having mounting means (e.g. mandrel 213, Fig. 4) for releasably and rotatably carrying an article 215 having a curved surface to be marked, means for effecting translational movement of the mounting means relative to the die supporting means and means for rotating the mounting means during the translational movement, whereby the article can be moved relative to the die supporting means with its curved surface in rolling contact with a die carried on the supporting means, and foil feed apparatus adapted to feed foil between the die and the article during return movement of the mounting means. Platen assembly.-Platen 101, Fig. 3, mounted on heater block 83 may be adjusted laterally by screws 107. Block 83 may be tilted about an axis extending front to rear, Fig. 3. The platen is adjustable vertically by shaft 75 and hand wheel 77. Shaft 75, supported in plate 63 is mounted on bars 25, 27. B or 25 is attached to a member 33, Fig. 5, to permit tilting of the platen assembly for inspection and replacement of the die. Clamp 41 secures bar 27 in the operative position. Article support means.-Cross-member 153, Fig. 4, is movable relative to platen 101 on guide bars 155 and 157, Fig. 2, and carries a mandrel 213 supporting an article 215. The mandrel is rotated by pinion 193 engaging a rack 195 on bar 197. The end of the mandrel is supported during movement by ball races 261 and 263. Article ejector rod 217 pushes the marked article from the mandrel when struck by a plunger from compressed air ejector cylinder 245. Foil feed.-Pigmented foil is fed from roll 115 around guide wheels 126, 127 on to driven roller 123 and take-up roller 135. The foil is advanced stepwise during return movement of the article supporting mandrel by a pinion 141, Fig. 6, engaging rack 143 carried on frame 144 which is retained for movement parallel with the guide bars by a rod 147 attached to the frame slidable in guide 145. Frame 144 moves with member 153 during the working stroke until collar 150 on rod extension 149 engages guide 145. During this movement pinion 141 is rotated but not roller 123. On the return stroke, when head 153 engages arm 151, frame 144 is moved back to its initial position and the foil is advanced as pinion 141 is turned. The position of collar 150 determines the length of foil fed. Operation.-Head 153 carries plate 231 which bears a trip lever 233 to trip pneumatic valves 239 and 241 controlling damping. Head 153 is carried forward by the piston of air cylinder 165 and the speed of movement is controlled by oil filled damping cylinder 167 which permits a fast approach of mandrel 213 up to the die, a slower controlled speed of the mandrel during marking, a fast movement of the mandrel to the ejector station and a fast return to the initial position.

Patent GB-651412-A (GB)
Title: Improvements in or relating to process of preparing procaine penicillin and the product resulting therefrom
IPC: C07D499/24
Filed: 1948-02-03
Abstract: The procaine salt of penicillin (especially penicillin G) is manufactured by bringing together penicillin and procaine in a solvent in which procaine penicillin is relatively insoluble, with the procaine and penicillin in solution in amounts to form substantially more procaine penicillin than will dissolve in the solvent, and with the penicillin present in a purity of at least about 75 per cent, and separating the resulting precipitate.  The process may be effected by reacting in aqueous solution a penicillin salt (e.g. its sodium, potassium or ammonium salt or a water-soluble salt thereof with an organic nitrogenous base such as N-ethylpiperidine) with a procaine salt (e.g. hydrochloride, sulphate, nitrate or formate), or by reacting penicillin (acid) with procaine (base) in an organic solvent or mixture of solvents in which procaine penicillin is relatively insoluble (e.g. an alkyl acetate having 4-9 carbon atoms, such as amyl, isoamyl, butyl or hexyl acetate, or, less suitably, ether or chloroform). Examples are given of both procedures and of medicinal preparations of the product, in one of which phenol is added as a preservative.  The Specification as open to inspection under Sect. 91 comprises also a reference to the calcium salt of penicillin as a starting material.  This subject-matter does not appear in the Specification as accepted.ALSO:An injectable medicinal product comprises finely divided procaine penicillin (especially procaine penicillin G) in suspension in an aqueous medium, or in a vegetable oil (e.g. cottonseed, peanut or sesame oil) or an oily medium containing a small amount of hydrogenated vegetable oil (e.g. partially hydrogenated peanut oil), or in an aqueous emulsion of a vegetable oil (preferably stabilizing with a small amount of a water-soluble and of an oil-soluble emulsifier).  The procaine penicillin and the liquid in which it is to be suspended may (especially when the latter is or contains water) be put up in separate sealed vials and mixed just before use.  Detailed examples are given, in one of which phenol is added as a preservative.

Title: Improvements in or relating to irradiating apparatus
IPC: A61N5/06
Filed: 1970-01-23
Abstract: 1,248,192. Control systems for discharge tubes. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 23 Jan., 1970 [28 Jan., 1969], No. 3323/70. Heading H2H. An irradiation apparatus comprises a gas discharge tube which is provided with devices which shield the radiation from the tube until the tube has reached its normal operating condition. A high pressure mercury vapour tube 5, provided with a starting electrode, is connected in series with a ballast resistor 4 and the contact 6 of a time switch T2 across an A.C. supply 1, 2. Connected across the ballast resistor 4 is a parallel circuit comprising a relay winding 7 and a changeover switch 11 in one branch and a contact 8 of relay 7, a contact 9 of a second time switch T and the energizing coil 10 of an electromagnetic solenoid in the other branch, the solenoid having core members 25, 25a which are operative to move the radiation shielding members 30, 31 along the discharge tube 5. Initially, upon closure of a switch 3 and before the tube 5 has ignited, no voltage appears across the resistor 4. Thus, although the contacts 6, 9 are closed by energization of the timers T2, T1, the coil 10 remains unenergized and thus the members 30, 31 are in a position to completely shield the tube 5. When the tube 5 ignites, but before it reaches its normal operating condition, the volt drop across the tube is low and hence the drop across the resistor 4 is high, thereby energizing coil 7 sufficiently to open contact 8. The coil 10 remains unenergized until the tube 5 reaches its normal operating condition when the volt drop across the tube 5 rises and that across the resistor 4 falls when the coil 7 is no longer able to maintain the contacts 8 open. Closure of these contacts then causes energization of coil 10 to move the members 30, 31 to the ends of the tube 5 allowing radiation therefrom to take place. When the timer T1 times out contact 9 opens to de-energize coil 10, thus returning members 30, 31 to their shielding positions. Timer T2 still maintains contact 6 closed, thereby maintaining the tube 5 in its normal operating condition until this timer times out. If during this period it is desired to use the irradiation apparatus, the coil 10 can be energized by moving the changeover switch 11 to its right-hand contact.

Abstract: 977,250. Toothed gearing; valves. E. WICHMANN, and R. SCHMINKE. Aug. 16, 1963 [Aug. 24, 1962], No. 32474/63. Headings F2Q and F2V. [Also in Division H2] Closure of switch 25 in the circuit of contactor 23 energizes electric motor 2 to close valve 22. At the beginning of downward movement of slide 21, switch 27 is closed to short-circuit limit switch 10, but, after the slide leaves the top position, the circuit of contactor 23 is maintained only by the switch 10. If the slide meets an obstacle, gear 3 is moved upwardly against the force of spring 6 so that switch 10 is opened to stop the motor. The same operation takes place when the slide reaches its lower position. The valve is re-opened by actuating switch 26 in circuit with contactor 24. If the slide 21 has jammed in its bottom position, gear 3 moves downward against the force of spring 7 to actuate limit switch 11, which is bridged by switch 28 however. Further movement of gear 3 displaces the limit switch 11 as a unit against the force of spring 15. As soon as the slide 21 is released to begin its upward movement, the switch 11 is released and resumes its control function for the contactor 24. Maximum torque limitation is provided by additional limit switches operated by extreme movement of the gear 3, or by the housings of switches 10, 11, when the latter are moved through a certain distance. The switchactuating element 29 may be replaced by a time device which keeps the switches 27, 28 closed for an initial period. In another embodiment, a link is engaged by a cam on shaft 5 just before slide 21 reaches the top limit position. This displaces switch 10 against spring 14 so that the gear 3 must move a greater distance against the force of spring 6 before it can actuate switch 10. The limit switch will thus respond only to a higher torque during initial movement in the downward direction, Fig. 3 (not shown).

Abstract: 1535262 Tractor/trailer braking system BENDIX CORP 29 Jan 1976 [6 March 1975] 03567/76 Heading F2F To provide controlled trailer braking on failure in a coupling 46 or trailer service brake control line 44 the trailer emergency brakes are actuated as a result of operation of a pressure differential valve 72 in response to a predetermined differential between a port 76 communicating with a drivers control valve 24 and a first portion (the tractor service brake lines) and a port 70 communicating by a line 68 with a second portion (the trailer service brake line) of the braking system. In a pneumatic braking system, shown in its inoperative condition, actuation of a manual push-pull valve 26 connects an accumulator 14 through a valve 84 and via a chamber 56 of a tractor protection valve 40 to pressurize and release the trailer emergency brakes. Pressurization of the chamber 56 raises a piston 54 to connect the trailer service line 44 through a double check valve 36 with the higher pressure one of tractor service brake lines 28 and 30. Normal operation of the drivers valve then controls all the service brakes. Upon failure in the trailer line 44 or coupling 46, operation of the drivers valve 24 pressurizes from the line 28 the port 76 of the valve 72 displacing the pressure differential responsive piston 92 downwards and unseating the valve element 86. This connects a second inlet 78 from the line 28 to an outlet 80 and thence to an inlet 82 to lift a piston 112 of a valve 84. This closes valve elements 106, 108 and exhausts through a piston passage 122 and exhaust port 104 the line 62 to apply the trailer emergency brakes and the chamber 56 permitting the spring 52 to lower the piston 54 of the tractor protection valve 40 to isolate the trailer service line. On release of the drivers valve the valves 72, 84 and 40 return to the positions shown to release the emergency brakes.
