Patent GB-777386-A (GB)
Title: Synchronizing system
IPC: H02P5/74
Filed: 1955-02-21
Abstract: 777,386. Synchronizing arrangements. INTERNATIONAL BUSINESS MACHINES CORPORATION. Feb. 21, 1955 [Feb. 24, 1954], No. 5113/55. Class 38 (4). A system for synchronizing the operation of two independently driven machines comprises synchronous generators 10, 12, driven respectively by the two machines and connected in a closed loop so that electric power may pass between them and thus equalize the speeds of the machines, there being included in the loop a reversing relay R which is repeatedly actuated by a cam switch S6, whereby one of the generators is caused to drop back a pole each time the relay reverses and the two machines thus progressively brought into closer phase agreement. Contacts S5, controlled by a relay R3, open when the two machines are in phase, to prevent further operation of the reversing relay. The generators 10, 12 are of the multipole type and are coupled to their machines through a high ratio step-up gear, so that the dropping back of one generator by one pole results in a phase change between the two machines by only a few degrees. When approximate phase correspondence is attained, overlapping closure of cam switches 14, 16 which are operated, respectively, by the machines once per revolution, causes operation of a relay R2, which at contact S9 completes the anode circuit of a thyratron T and at contact S7 completes a holding circuit, which also includes a normally closed contact S8 of a relay R6. The thyratron is, however, held off by bias from the main D.C. source c, d until overcome by a synchronizing voltage pulse which is developed across a resistor 60 when (a) conductive segments 18, 118, carried by and connected to the slip-rings 32, 134 of the two generators, both engage their corresponding brushes 22, 122; (b) the voltages of the two generators are additive; and (c) a cam switch S10, driven by one of the machines, is closed. Under these conditions the machines are in exact phase agreement. The synchronizing pulse fires the thyratron, the anode current of which energizes relay R3 (over coil 54) to open S5 and stop further operation of reversing relay R1. Contacts S11, S13 are closed by operation of R3; S11 closes a circuit for a holding coil 64 for relay R3 and S13 completes an energizing circuit for relay R6 which, at contacts S14, disconnect sparksuppression condensers C3 from the contacts of the reversing relay and, at contact S8, prepares relay R2 and thyratron T for de-energization, which occurs when cam switch S15 opens. If synchronism should be lost, resynchronization may be started by opening a switch S12 to interrupt the holding circuit for relay R3.

Patent GB-781843-A (GB)
Title: Pretreatment of aqueous nutrient-containing fermentation media to improve the yield of tetracycline therefrom
Inventor: MINIERI PASQUALE PAUL
Filed: 1956-02-21
Abstract: An aqueous nutrient containing fermentation medium for the production of tetracycline using a tetracycline-producing-species of Streptomyces is contacted with an anion exchange resin to reduce the chloride ion content thereof and thereby improve the yield of tetracycline.  The chloride ion content should be reduced to less than 50 parts per million and preferably less than 10 parts per million.  Mixed beds of anionic resin and cationic exchange material are used where it is desired to remove cationic groups, e.g. metallic cations present in sufficient amounts to poison the nutrient medium. It is preferred to treat naturally-occurring materials such as corn steep liquor, animal stock liquor (crude mixture obtained from slaughter houses), starch and casein digests, and then to add the other ingredients of the fermentation medium, especially the mineral salts, to the de-chlorinated material.  The fermentation medium contains a source of carbon, nitrogen and mineral salts.  Viscous liquids are first diluted with water before passing through a bed of the ion exchanger.  Insoluble materials may be washed with deionized water to remove chlorine ions.  The anion exchange resins are any water-insoluble resins which will adsorb or otherwise remove chloride ions from aqueous solution, e.g. phenol-formaldehyde-polyamine condensates, melamine-guanidine-formaldehyde resins and polyalkylene polyamine resins.  The resin may be operated in various forms such as the sulphate, nitrate, hydroxyl and phosphate cycles.

Title: Improvements in reservoir ruling or marking instruments
IPC: B43K8/20
Filed: 1925-02-26
Abstract: 245,961. R÷hrich, C. Feb. 26, 1925. Reservoir rulling pens; ink-supply arrangements. -A reservoir ruling or marking instrument is provided with a piston for adjusting the volume of the reservoir and a device for regulating the flow of ink. The regulating device may consist of a valve automatically or manually operated, in which case a spring-pressed piston may be used, or a rubber sleeve fitting over openings formed in the reservoir, when a piston adjustable by hand is provided. As shown in Fig. 2, the marking- member consists of a wheel 3 mounted in the front end of the instrument, the wheel being detachably held in place by means of a cover-plate 4 and screw 5. The axle of the wheel is provided with a part-circumferential groove 15 communicating with a channel 23 leading to the wheel, and with a circumferential groove 18 communicating with the passage 19 leading from the reservoir, the grooves 15, 18 being connected by a slot in the journal for the axle. A spring-pressed piston, provided with a chain for facilitating withdrawal, is mounted in the reservoir. In a modification of this form, the wheel 3 is arranged at right angles to instead of in line with, the axis of the holder. In the form shown in Fig. 4<a>, the wheel 45 is carried in a head 46 which is movably mounted on an extension 41 of the reservoir, a sleeve 44, rigidly connected to the head, serving as a pivot. The head is normally held by a spring 55 in such a position that a passage leading into the sleeve is out of alignment with the passage 42 leading from the reservoir, but arranged so that pressure on the wheel when in use moves the head into position to permit the flow of ink. As shown in Fig. 5, the volume of the reservoir is adjusted by means of a piston 65 having a screw-threaded rod 64, and outflow of the ink through a nozzle 61 is obtained by pressure of the fingers on a rubber sleeve 63 arranged over a number of apertures 62 in the barrel. In a modification of this type the nozzle is replaced by a wheel rotating in contact with an inking- pad mounted in the end of the reservoir.

Title: Improvements in cement kiln systems
IPC: B01D45/10
Filed: 1923-02-24
Abstract: 214,779. Babcock & Wilcox, Ltd., (Babcock & Wilcox Co.). Feb. 24, 1923. Dust, separating from gases. - Dust-laden cement-kiln gases are caused to deposit their solid contents in caked form on the heated walls of flues provided with baffles, or on heated rotating rods or surfaces. The caked materials may be removed while the operation of the kiln continues ; and a non-caking dust may be deposited at the same time as the caking material. In the plant shown in Fig. 2, the waste gases from rotary cement kilns 2 are discharged into the bases 4 of stacks 5 connected, through damper-controlled opening 9, with common settling flue 7 having hoppers 8 between the kilns and having inwardly projecting wing walls which cause eddying and assist the deposition of dust in the hoppers and of caking material on the walls. The loose dust may be discharged from a hopper, and the caked material chipped off the surrounding walls and separately removed, the cleaning being effected by devices 15 lowered by chains from windlasses 18, and swung from side to side by bars 19 inserted through the flue top, or a bar 15<a> may be suspended from a pair of chains. The roof and upper parts of the walls may be reached by curved bars. The, gases pass from the flue to heat a waste heat boiler 22 below which hoppers having cleaning means are set. The gases escaping from the boiler may, as shown in Fig. 5, be passed by a fan 30 into centrifugal separators 40. In this arrangement of apparatus water is drawn from the boiler 25 and passes to a. settling chamber 25<1> whence it is forced by a centrifugal pump 32 into an economizer 28 through a pipe 34 which also receives feed water from a heater 35 heated by steam from a turbine 38 which drives the fan 30. The centrifugal separators may be replaced by a settling chamber with vertical baffles. A modified apparatus for collecting the caking portion of the material consists of rods disposed in the flue and rotated either independently, as shown in Fig. 21, or as a set forming a flat rack or a cylindrical cage, the individual rods being either fixed or rotating; or screens of non-rotating rods may be disposed transversely in the flue and lifted or lowered through slots in the top of the five by chains passing over pulleys. The rods next to the wing walls may be provided with chisel portions to scrape the wing walls in being raised or lowered. The centrifugal or gravity separators employed for separating the dry dust may be replaced by electrical dust precipitators.

Title: Rotary drive mechanisms
IPC: F16D48/02
Filed: 1974-02-06
Abstract: 1465834 Change-speed gear; friction clutches COAL INDUSTRY (PATENTS) Ltd 22 Jan 1975 [6 Feb 1974] 05428/74 Headings F2D and F2C Two-speed epicyclic gearing suitable for accelerating a loaded conveyer from rest comprises a sun wheel 32 splined at 31 to a driving flange 11 driven by an electric motor shaft 2, an internally toothed ring gear 52 with a driving connection with a shaft 5 of an output gear-box 6, a planet carrier 36 with pairs of intermeshed planet wheels of which one 35 of each pair meshes with the sun and the other 37 with the ring gear, clutch means including discs 40, 41 splined at 38, 39 to an extension of the carrier whereby the latter may be held stationary or driven by the input shaft 2, and a pump 18 driven by the input, e.g. by an eccentric, for feeding pressure fluid to a valve assembly (not shown) controlling the clutch means. Both clutch discs are urged by springs (not shown) to their disengaged positions so that no drive is transmitted when the motor is started up. After a time delay which, on starting, allows the motor to reach its full speed a solenoid valve (not shown) is energized to admit pressure fluid to a conduit 48 and thrust ring 49 to engage a frustoconical surface 43 of the disc 41 with a surface 44 of a stationary ring 45 so that the disc 41 and carrier 36 are brought gradually to rest. A sequence valve (not shown) is then operated to admit pressure fluid through a conduit 47 to a chamber 50 so that the disc 41 is held without slip. After a further time interval the pressure on the disc 41 is released and another solenoid valve (not shown) is opened to admit pressure fluid through a conduit 24 to a thrust ring 28 and subsequently past a spring-loaded centrifugal valve 27 to a chamber 29, this action bringing the conveyer up to full speed by clutching the carrier 36 to the input shaft 2. There may be overlap between the operation of the solenoid valves to avoid slowing of the conveyer during changeover. In a modification the motor shaft 2 is hollow and the output shaft 5 passes through it. A brake, arranged to be released when either of the clutch means is engaged, may be associated with the output shaft. A further modification is referred to in which the intermeshed planets are replaced by single planets meshing with both the sun and the ring gear, such arrangement causing reversal of the output on changeover of clutch engagement.

Title: Automatic phonographs
IPC: G11B3/08
Filed: 1942-04-27
Abstract: 556,974. Phonographs. PHILCO RADIO & TELEVISION CORPORATION. April 27, 1942, No. 5623. Convention date, May 15, 1941. [Class 40 (ii)] A trip mechanism for causing the lifting of the pick-up of a phonograph when the pick-up arm is given a quick inward movement by an inner eccentric groove on the record disc comprises electric contact members 56, 57, Fig. 3 one of which, 56, is made to approach the other, 57, by the inward movement of the pick-up arm and the second of which, 57, is periodically moved away from the first, so that contact is not made until the quick inward movement of the pick-up arm occurs which movement is sufficient to make the contact member 56 reach the contact member 57 before this member is moved away. The contact member 56 is attached by a stump 54 to one prong of a fork 43. The other contact member, 57, is attached to a block 50 slidable on a stem 55 attached to the other prong of the fork 43. The fork 43 is on an arm 42, Fig. 1, fast with the pick-up arm 4 on a vertical rotatable spindle 5. The fork rides between a fixed rail 44 and a plate 46 at one end of a lever 47 which is pivoted at 48 and has a roller 49 on an arm 47a at its other end in the path of projections 26 on a disc 22 driven by gearing from the turntable spindle 3. Normally, the plate 46 under the influence of a spring 52 grips the block 50 and holds it at rest while the arm 42 follows the inward playing movement of the pick-up arm. Periodically, during play, the projections 26 deflect the lever 27, thereby releasing the grip on the block 50 and allowing the contact member 57 to be sprung away from the contact member 56 by a spring 51, Fig. 3. The quick pitch of the inner groove of the record, however, gives a larger displacement sufficient to make the contact member 56 reach the contact member 57, whereupon an electromagnet 58 is energized and its armature 59 turns a trigger 38 off a stud 40 on a lever 19. A spring 36 then turns the lever 19 about its pivot 27 and brings a lug 60 on a pivoted catch 30 on the lever in the path of cam 29 on the disc 22. The catch 30 is turned by the cam from one end position determined by a lug 32 on the lever 19 to another end position determined by a lug 31 on the same lever. A toggle spring 33 holds the catch in its extreme positions. Continued rotation of cam 29 then turns the lever 19 about its pivot 27 and brings the curved end of the lever against one arm 13, Fig. 2, of a bell-crank 8, thereby turning this bell-crank and lifting a rod 17 attached to the other end of the bell-crank. The rod, 17 when thus lifted, raises the pick-up off the record. The bell-crank 8 is pivoted at 10 on a lever 9, which is pivoted at 11 on the vertical spindle 5 of the pick-up arm 4 and carries a cam follower 21 at its end, When the bell-crank is subjected to the weight of the lifted pick-up, the lever 9 is turned down about its pivot 11 and the cam follower 21 engages a cam groove in the upper face of the disc 22, this causes the pick-up arm 4 to be swung out.
