Title: Chain arrangement in rotary tube furnaces
IPC: F27B7/16
Filed: 1931-05-22
Abstract: 373,409. Rotary furnaces. JACKSON, L. MELLERSH-, 28, Southampton Buildings, London.-(Krupp Grusonwerk Akt.- Ges., F. ; Buckau, Magdeburg, Germany.) May 22, 1931, No. 15223. [Class 51 (ii).] In a rotary furnace heat-transmitting chains are tightly stretched, loosely suspended from both ends, or suspended from one end only, at least two of these methods of suspension being used together. When tightly stretched chains are used, the loose or freely suspended chains are arranged to contact with them during the rotation of the furnace, or loose chains may be interwoven with parallel stretched chains to form a network or sieve. A number of these networks mav extend across the furnace with the chains of one displaced through an angle relatively to the chains of the others, and loose or free chains may be suspended in the spaces between the networks. In the arrangement shown in Fig. 4 chains 22 are stretched across a ring 20 between which and the furnace wall are loose chains 23. In another arrangement, Fig. 5, a perforated plate 25 is fixed centrally in an enlarged part of the furnace, and loose chains 27 are suspended between the edge of this plate and the furnace wall, and others 29 extend across the furnace. Free chains 28 are attached to the edge of the plate, and others depend from the wall. The charge may be cascaded by lifting-shovels 30. In a further modification loose chains are suspended in the space between two discs centrally mounted in the furnace by radial stretched chains. The loose and free chains may be weighted.

Title: Improvements in or relating to telephone systems
IPC: H04Q3/00
Filed: 1921-06-01
Abstract: 165,030. Automatic Telephone Manufacturing Co., Ltd., (Assignees of Baer, F. L.). June 18, 1920, [Convention date]. Automatic and semi-automatic exchange systems.-A trunk 30, 31 from an automatic to a manual exchange is provided at its outgoing end with a device E, which responds to the impulses representing the surplus digits of the called number and which only closes the trunk circuit, to signal the distant operator, when all such impulses have been received. The impulses received by relay 5 control a slow-release relay 8 and magnet 23 to advance a switch 19, 20 one step for each digit. After the last digit, the switch arm 19 completes a bridge circuit across the trunk 30, 31, energizing relay 7 in series with relays 33, 34, which light a calling lamp L and transmit an induction ringing tone to the calling line through a small capacity 51. The operator's reply energizes a sleeve relay 35, which disconnects relays 33, 34 and de-energizes relay 7, the trunk circuit being now metallically interrupted by condenser 52. If the call is from a subscriber not entitled to trunk service, the operator receives a tone signal over wire 17 and through transformer R; otherwise she completes the connection and momentarily presses key K to energize relay 37, which energizes relay 36. Both these relays lock themselves up, the upper winding of relay 37 being now bridged across condenser 52 so as to be energized in the supervisory circuit in series with relay 7, which open-circuits the primary of the tone-transformer R. After conversation, when the calling subscriber disconnects himself, the relapse of relays 5, 6 closes a circuit for magnet 22, which restores switch 19, 20, thus opening the trunk circuit to give a clearing signal to the operator. If the trunk should be seized again before the cperator withdraws the answering- plug, being again bridged at its outgoing end through relay 7 and switch arm 19, relay 33 is not energized, its circuit being open at contact 45, but relay 34 is energized, over contacts 43, 46, 48 and the trunk loop, and flashes the lamp L by connecting it to interrupter I. The operator then momentarily withdraws the answering plug, to unlock relays 35 36, and deals with the call as before described. For testing purposes, a telephone may be bridged across the trunk by plugging into a jack J<1>, a relay 32 being energized at the same time to separate the incoming and outgoing sides of the trunk and to energize relay 7, which marks the trunk busy by grounding wire 17.

Title: Improvements in Devices for Detachably Connecting Electric Conductors to the Terminals of Magnetos and other Electrical Apparatus.
Inventor: JOSEPH GEORGE FREDERICK
IPC: H01T13/04
Filed: 1918-09-20
Abstract: 121,105. Joseph, G. F., and Harding, A. I. Sept. 20, 1918. Cable and wire terminals. - In means for detachably connecting electric conductors to the terminals of magnetos &c., the conductor is fixed to one end of a tube 4 of conducting-material containing a plunger 9 which is pressed against a stop 5 in the tube by a spring 12, the tube being provided with a cam-slot having an enlarged end 6, and the plunger with a circular aperture 11 to receive the lead 7 of a terminal stud in such a way that the parts are locked by giving an endlong and an angular movement to the tube. The front end of the plunger has teeth 10 to engage with the stop 5, and the engagement normally keeps the parts in such position that the enlarged end 6 of the slot and the aperture 11 are opposite each other. The stud can then be introduced and the coupling is secured by pressing forward and turning the tube 4, so that the narrow end of the cam-slot engages with the stud and the stop 5 engages between other teeth in the plunger, the neck of the stud being pressed by the plunger against the forward edge of the cam-slot. The conductor 1 of the cable passes through a screwthreaded ferrule 3 and is secured at the front end by solder.

Title: Rapid processing photographic apparatus and method
Inventor: WRIGHT JOSEPH HAROLD
IPC: G03B17/50
Filed: 1961-04-27
Abstract: 930,338. Processing apparatus for photographic film. PHOTOMECHANISMS Inc. April 27, 1961, No. 16311/61. Class 98 (1). Processing liquid is applied to a film after exposure by means of a porous applicator through which the liquid exudes, the film and applicator being supported just out of contact with each other, so that the liquid passes from one to the other by capillary attraction. Fig. 19 shows schematically, and Fig. 7 in more detail, a self-contained camera unit for exposing and then developing a film. The film 36 unwinds from a supply cassette 35 and passes through the gate 138 of a lens and shutter assembly 42 where an exposure is made. It then passes round a support plate 38 which locates it just above an applicator shoe 34 comprising an upper block 184 and a lower block 186. The shoe 34 is in fact designed to apply two separate processing liquids one after the other, firstly a developing solution and then a fixing solution. These are contained respectively in tanks 188, 190, and are conveyed by a pump 44 to the lower block 186, where they are heated by thermostatically controlled heating means to an appropriate temperature. From the lower block they pass into the upper block 184, being channelled into respective chambers 248, 254 in the block. The chambers are filled with dampening wicking, and covered with respective porous shoes 252, 258. The liquid is forced through the shoes by a slight positive pressure, and on to the film 36, filling the space between shoe and film by capillary action. A spacing of about six to ten thousandths of an inch is contemplated. The respective areas of liquid in contact with the film are limited by the meniscal boundaries, and a separating squeegee 259 is provided between them. A waste tank 192 is provided for receiving excess developer and fixer solutions draining from the processing block. The film then passes up the face of a lamp housing 49 containing a number of lamps 312, which illuminate the film so that the processed film can be inspected through a viewing window 78. In this section of the apparatus the film is dried by a hot air blower (not shown), and it finally passes between rollers 166, 158 to leave the apparatus through slot 72 in the housing cover 62. The flow of processing liquids and the film travel rate may be synchronised.

Title: Improvements in the manufacture of highly polymeric polymethylene terephthalates
Inventor: ISAACS ELIAS
IPC: C08G63/85
Filed: 1955-05-27
Abstract: In a process for making highly polymeric polymethylene terephthalates by reacting a glycol of formula HO(CH2)nOH (where n is 2-10) with terephthalic acid or an ester-forming derivative thereof, and polycondensing the resulting glycol terephthalate, at least the polycondensation step is effected in presence of an organic titanate, especially an alkyl or aryl titanate.  An additional polycondensation catalyst may be used, e.g. antimony oxide, and when starting from a dialkyl terephthalate, an esterinterchange catalyst may be used, e.g. zinc acetate.  Part of the terephthalic acid may be replaced by another dicarboxylic acid (e.g. isophthalic acid in the form of dimethyl isophthalate) and a mixture of two glycols of the above series may be used.  Titanium dioxide, which acts as a delustrant, may also be present during the polyesterification.  In examples: (1)-(9) ester-interchange was effected between dimethyl terephthalate and ethylene glycol in presence of tetramethyl or tetrabutyl titanate and in some examples also in presence of zinc acetate at 149-218 DEG C. and the resulting glycol terephthalate polycondensed at 275 DEG C. and 1 mm. of Hg. pressure; (10) terephthalic acid and ethylene glycol were reacted at 230 DEG  C. and 35 lbs./sq. inch and the resulting glycol terephthalate polycondensed at 275 DEG  C. and 0.3 mm. of Hg in presence of tetramethyl titanate and titanium dioxide. Subject-matter in Specification 769,220 is disclaimed.

Title: Improvements in or relating to change-speed gear units for tractors
Inventor: PAVER GEORGE HENRY
IPC: F16H3/16
Filed: 1956-05-17
Abstract: 824,186. Change-speed gear; gearing for stopping and starting machinery. INTERNATIONAL HARVESTER CO. OF GREAT BRITAIN Ltd. (International Harvester Co.). April 25, 1957 [May 17, 1956], No. 15396/56. Class 80 (2). [Also in Group XXXI] A change-speed gear unit wherein drive is transmitted from a clutch sleeve 1 to a driven shaft 2 through selective gear ratio means and the clutch sleeve 1 is selectively driveable from a primary drive shaft 17 either directly or through reduction gearing, has a friction clutch 22 in the drive through the reduction gearing to the clutch sleeve and a power takeoff shaft 33 in constant driving connection with the primary shaft 17 through the reduction gearing, the clutch 22 being operable to disengage the drive to the clutch sleeve 1 while drive to the take-off shaft 33 is maintained. The latter is connected by an auxiliary shaft 32 and a pair of constant mesh gears 20, 21 to the primary shaft 17. A lay shaft 3 surrounds the auxiliary shaft 32 and carries gears 5 . . . 7 to cooperate with gears 9 . . . 11 slidably splined on the shaft 2 for operation by a gear lever 12 and selector mechanism to provide three gear ratios, a fourth ratio being provided by sliding a gear 4 to the left to couple the clutch sleeve 1 directly to dog clutch elements 2a on the shaft 2. The gear 11 also co-operates with reverse gears (not shown). For road use, the clutch sleeve 1 is connected to dog clutch elements 17a on the shaft 17 by movement to the right of an outer clutch sleeve 18 and drives the lay shaft 3 through the gear 4 and a gear 5, while for field use, the lay shaft 3 is driven at a lower speed through the friction clutch 22 and the gears 20, 21. The clutch is biased by springs 26 to the disengaged position and is moved to the engaged position by a thrust collar operated through a pair of levers 28 from a hand lever 34. Cams 36 on the lever 34 engage rollers 28b on the levers 28 and are arranged so that the clutch 22 is fully disengaged when the lever 34 is in mid position, a friction lining 30a co-operating with a taper 7a on the gear 7 to bring the shaft 3 to rest to facilitate gear changing. Further movement of the lever 34 causes a lug 37 mounted on the same shaft as the cams to engage a slot 38 in a selector rod 13 controlling the clutch 18 and causes cams 36b to move the collar 30 to a position in which the clutch 22 is disengaged but the friction lining 30a is clear of the taper 7a. The gears 5 . . . 7 and 9 . . . 11 may alternatively be of the constant mesh type.

Title: Improvements in the commutating gear of high tension direct current apparatus
IPC: H02K13/00
Filed: 1924-06-26
Abstract: 238,046. Calverley, J. E., and Highfield, W. E. June 26, 1924. Brush-holders; commutators. - In commutating gear for use with a number of coaxial commutators adapted for connection in series through their brushgears, the brush carriers are insulated from the supporting member and from each other by an arrangement of the condenser type comprising alternate layers of insulating and conducting materials, definite potentials being established on the conducting layers by connecting some or all of them electrically with the respective brush carriers. The shaft 1 has an insulating tube 2 of mica &c., and upon this are built up alternate tubes of conducting material 6 and insulation 5. At the high-tension end of the shaft (lefthand side of the Figures) the insulation extends over the conducting layer next beneath, but at the other end, a short length of conducting layer is left uncovered, and on to this portion a brushsupporting ring 13 is shrunk. The conducting layers may consist of copper foil enclosed in a shrunk-on steel cylinder or secured by a double layer of wire wound on under tension. The stepped ends of the insulation at the high-tension end are enclosed in a hollow cylinder 14, and the space is filled with an insulating compound 40. Brush carriers 23 are rigidly secured to the rings 13 and, with the exception of the brush carrier at each end, are formed with two arms 21, 22, the brushes of which engage with adjacent commutators 26 .. 29. The end rings have one brush arm, and are also arranged with slip-rings 31, 32. In some cases, the arrangement may be made symmetrical about a centre plane, the two sets of commutators on each side of this plane being connected in parallel so that the potential rises from the two ends symmetrically to the centre. Tappings may be brought out from the metallic layers through the insulating compound 40. Specifications 140,853, 150,824, 150,825, [all in Class 38 (ii), Electric currents, Converting &c] ; 214,698; and 216,690, [Class 38 (ii), Electric currents, Converting &c.], are referred to.
Patent GB-593648-A (GB)
Title: Improvements in or relating to the production of artificial stone
IPC: C04B28/18
Filed: 1945-06-18
Abstract: Artificial stone is produced by partially hydrating comminuted lime by treatment with water vapour at a temperature of above 100 DEG C. or with water dispersed in air, mixing the partially hydrated lime with a siliceous or argillaceous material, adding water, moulding or otherwise shaping the mixture to the required form, allowing the lime in the mixture to hydrate completely, and hardening the composition by the action of steam under superatmospheric pressure.  In a modification unhydrated lime and the siliceous or argillaceous material are ground together in an air-swept mill and partial hydration of the lime is effected simultaneously by introducing a controlled amount of steam into the air current.  The product may be rendered cellular by forming gas bubbles in the mixture, e.g., by incorporating aluminium powder.  Specification 245,935, [Class 22], 455,039 and 560,824, [Group III], are referred to.
Patent GB-355666-A (GB)
Title: Improvements in or relating to electrical methods of obtaining current impulses of predetermined frequency and shape
IPC: H03K3/04
Filed: 1930-05-21
Abstract: 355,666. Converting. STANDARD TELEPHONES & CABLES, Ltd., SKILLMAN, T. S., TERRY, R. ST. G., ROCHE, A. H., and FEDERICI, M. E., Columbia House, Aldwych, London. May 21, 1930, No. 15625. [Class 38 (ii).] To obtain current impulses of predetermined frequency and duration, the grid potential of a three-electrode valve is controlled by a resistancecondenser combination, the condenser of which is periodically charged from a source of potential by a switch periodically operated by a relay in the plate circuit. Assuming the switch 1, Fig. 1, is closed, the condenser C charges rendering the grid potential negative so that the valve becomes non- conductive and the relay Q opens the switch. The condenser then discharges through the resistance R until the grid attains such a potential that plate current flows to operate the relay Q to close the switch, thus recommencing the cycle. The relay Q opens and closes contacts in an external circuit. The frequency of the impulses, determined by the rate of charge and discharge of the condenser, can be varied by adjusting the resistance. In the circuit shown in Fig. 3, when sufficient plate current flows in valve T1 the relays A, B energize but immediately release since the relay A applies a negative potential to the grid of valve T1. Relay B applies a negative potential to the grid of valve T2 which causes the relay C to open and this remains open until the condenser in the grid circuit has discharged through the resistance R2. Thus the opening of the relay C is determined by the resistance-condenser combination in the grid circuit of valve T1 and its closure by the resistance-condenser combination in the grid circuit of valve T2. Fig. 4 shows a circuit for obtaining impulses of very short duration. The relay A periodically energizes and immediately opens thus causing the relays B, B1 to energize. These relays are so biased that they operate at different instants and the duration of current obtained is the difference in their operating times.
