Title: Improved means for steering trailers
IPC: B62D13/04
Filed: 1919-05-20
Abstract: 141,313. Hekking, A. L. P. April 5, 1919, [Convention date]. Articulated vehicles and road trains.-Comprises an improved road construction of the steering connexions between a tractor and a trailer of the kind in which the steering wheels of the trailer are defleeted by any relative inclination of the tractor and trailer axes, and in which provision is made for altering the position of the point of connexion of the rod which controls the said deflexion when it is desired to reverse the direction of propulsion. In the form shown in Figs. 1 and 2, a crank a on a shaft 1 journaled to the tractor is connected by a link 4 to a lever b, c pivoted at 5 to the trailer, the lower arm c being connected by a bell-crank d, e to the steering wheets. The pcsition shown is for backward travel; for forward travel the crank a is turned through 180 degrees. Two modifications of this form are described, in one of which the reversing crank is carried on the trailer. The adjustment may be made to occur automatically when the direction of propulsion is reversed. In an automatic form, illustrated in Figs. 9, 10, and 13, the trailer steering wheel is fitted with a drum 16 having holes 17 which gear with blades 18 carried by a nave keyed on a shaft 20 journaled in a lug 21 on the part 12 carrying the stub axle 14. A friction drum 23 is also fitted in this form and is surrounded by a friction strap 25 the hooked ends of which are connected by springs 29 to regulate the friction; the ends are also connected to the have 18<a> by crossed cables attached to the nave. The shaft 20 is connected to the shaft 1 of the crank a by a simple or compound spring 22. The rotation of shaft 20 is limited in either direction by a fixed stop 31. Upon reversal of the direction of rotation of the wheel, the blade last in engagement with the drum 16 on the forward travel once more engages the drum, and the shaft 20 is rocked and through the spring 22 reverses the crank a. Where the mechanism is carried on the tractor the blades 18 may be held out of action at the third and fourth speeds by connexions to a change-speed lever of the gate tyre. Fig. 14 shows the invention applied to a four-wheeled trailer with a steering front on the fifth-wheel principle, but the two rigid axles are replaced by stub-axles carrying mechanism, as described above. A V-coupling 40 connects the coupling hook 11 on the tractor to the trailer bogie, and a bar 8 connects the tractor to the arm b which is connected by a pivoted link 41 with the shorter arm b<1> of the rear-wheel mechanism.

Filed: 1974-03-22
Abstract: 1466424 Treating industrial dust HUTT GmbH 22 March 1974 [23 March 1973] 12916/74 Heading C1A Shaped masses are made from a blue dust which has surface constituents which contain at least one oxide, hydroxide, carbonate or carbon resulting from a mineral processing plant by adding to the blue dust 10 to 40% as binder a raw material used in said process in finely divided form, adjusting the moisture content if necessary and compressing the mixture into the desired shape. The shaped masses are preferably recycled. At least part of the dust may be used in the wet state and in any event the moisture content of the mixture is preferably adjusted to between 5 and 10%. The finely divided material with which the dust is mixed is suitably dustseparated in a dust separator disposed at the outlet from a mill for the raw material(s). The mixture is preferably granulated by a compression granulation and the granulate is suitably screened to separate granules of a size suitable for use in the process and a fine fraction, the fine fraction preferably being recycled for incorporation into the mixture to be granulated. In a preferred embodiment directed to the prereduction of lateritic ore for the production of ironnickel the gases from the ore mill and its associated dryer are fed to a pair of electrostatic filters 3, 4 and the exhaust gases from a rotary kiln are led to a further pair of electrostatic filters 6, 7. The gases from the filters 6, 7 pass to a further wet filter, e.g. one or more venturi scrubbers. Dust collected in the dry filters 3, 4, 6 and 7 are mixed in one or other of two blenders 8 and 9. Water may be added to the dry dust through line 10 in order to adjust the moisture content to 7%. The water from the wet filter is clarified and the resulting moist dust fed to the blender 8 via line 11. Sludge recovered from the wet filters is passed to a blender 8 along pathway 12 via a de-watering device 13. The damp mixture from the blenders 8 and 9 is fed to a reversible conveyer 17. In one direction conveyer 17 transfers material to a stockpile 19 and in the other direction material is introduced into a hopper 20 which feeds a pair of high pressure roller presses 22, 23 to produce granules of appropriate shape. The granules are screened and those larger than 5 mm. are collected and conveyed for recycling as raw material to the kiln. The fines are recycled to the roller presses 22, 23.

Title: Improvements relating to railway traffic controlling apparatus
IPC: B61L7/08
Filed: 1949-05-16
Abstract: 676,977. Railway signalling apparatus. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd., and SYER, A. F. April 24, 1950. [May 16, 1949] No. 12948/49. Class 105. To permit local operation of signals and points at a field station of a centralized traffic control system using coded current there is provided at the field station means whereby one of the normal codes, e.g. that for the clearance of a call-on signal, can be used to free the point and signal operating means for local control. The coded current centralized-trafficcontrol system may be that described in Specification 399,539. When local control is desired the local operator notifies the central office whereupon the office transmits a code which would normally result in a call-on signal control relay CH being energized by potential applied at line 41 but due to the local operator meanwhile closing a push button contact PB, a relay AR is energized whereby over a front contact A1 of this relay a relay LCO is picked up by the potential applied on line 41 instead of, as normally, the call-on signal control relay CH being energized from the line 41. The circuit for the relay AR and the stick circuit for the relay LCO respectively include normal contacts K(N), of a king lever KL, the circuit for the relay AR also includes a back contact A1 of the call-on signal control relay CH. Providing that local traffic conditions allow, as checked by the group of contacts denoted by A, the lock magnet of the king lever is now energized over a back contact of the relay AR(dropped when the push button was released), a front contact C1 of the relay LCO and a contact K(AE) of the king lever which can now be moved over to release the levers for local control of the signals and points. The movement of the king lever breaks the stick circuit of the relay LCO a back contact B1 of which prepares a point in the circuit to the code operated-call-on signal control relay CH which however remains open until the king lever is returned and closes contact K(NB). Since potential is still applied on line 41, this action by closure of king lever contact K(NB) will energize the call-on signal control relay CH and the clearance of this signal will send as described in Specification 399,539 a return code to the office and so notify that the local control is no longer required. The central office then sends a code to put the call-on signal to normal. Specification 526,751 also is referred to.

Title: Piano with electric playing means therefor
IPC: G10F5/02
Filed: 1961-04-11
Abstract: 990,164. Pianofortes. L. L. VON GUNTEN. April 11, 1961, No. 12966/61. Heading G5J. A piano has an auxiliary keyboard 5 like the bass keyboard of an accordion for playing chords in a control octave (B 11  to B 1 ). The keyboard may have additional keys for playing chords or single bass notes in other bass octaves. A.second auxiliary keyboard 6, when wiped by the fingers, produces an arpeggio of the treble notes that bear octave relations with the notes of a chord key 20 depressed in keyboard 5. Depression of one of the pedals 196 sustains a chord played by a key 20 and enables arpeggios to be repeated. The control octave may be coupled electrically to the higher octaves. Chord keyboard, 5, Each key 20 is mounted on a shaft 22, Fig. 8 carrying fingers 23, 24, 25, 26 which on depression of the key, engage fingers 28, 29, 30, 31 on some of the twelve switch operating members 33 which turn to operate switches 37a, Fig. 11. An additional finger 27 engages finger 32 on switch operating member 40 to operate switch 41, after the appropriate contacts 37a have been closed. Each switch 37a controls a solenoid 44, Fig. 7, for operating one hammer in the control octave. The armature 46 is coupled to the wipper 49 by an aluminium link 47, a spring finger 50 and a feet pad 51. When the solenoid is energized, the jack 48 operates the hammer. When the solenoid is unenergized, the action can be operated by the normal key unhindered by the pad 51. Some of the keys 20 may control switched 94 to operate single bass notes instead of chords, the solenoids being connected to the switches over leads 89, 90, 91 &c. Arpeggio keyboard 6, and electric action Figs. 1, 2,10,13. Each arpeggio key 66 controls a pair of spring contacts 67, 68. Playing keys 3, 4 pivoted on the usual manner carry armatures 60. A solenoid 59 associated with each armature enables the playing keys to be operated electromagnetically. All the contacts 67, 68 may be closed simultaneously by an insulating bar 98 raised by an electromagnet 102. The treble keys are then coupled to the control octave. Circuitry. A transformer 10, Fig. 12 has three tappings 16, 17, 18 feeding a rectifier 13 which accordingly gives three different output voltages on lead 19. One tapping is selected by a three position switch 97 to control the loudness of tone. The chord control unit 5a Figs. 11, 12 operates the appropriate solenoids 44 over leads 70, 71 &c. whenever a chord key 20 is depressed, voltage being supplied over lead 42 to switch 41. As shown in Fig. 5, depression of a playing key 3 closes a switch 75, and as shown in Fig. 12, connects voltage to switches 66 for the same note in higher octaves. If switches 66 are already closed by the coupling bar 98, as described, the same notes sound simultaneously in the control octave and in higher octaves. When switch 86 is operated against a spring bias, (as by a pedal 196), any key depressed in the control octave is held down by its own coil 44. Specification 990,165 is referred to.

Abstract: 1462273 Printers CASIO COMPUTER CO Ltd 22 March 1974 [24 March 1973 3 July 1973 (3) 14 Aug 1973] 12972/74 Heading G4H A pointer comprises a print drum bearing a plurality of rows and a plurality of columns of characters and both rotatable and axiallymovable to bring the characters to be printed adjacent a hammer, the hammer being movable parallel to the drum axis to reach the position at which the next character is to be printed, the amount and direction of the axial movement of the drum being controlled in accordance with a comparison of the circumferential column of characters on the drum containing the character to be printed with that (indicated by a stored value) containing the last previous character printed. The last and present columns may be compared using a matrix of ANDs feeding ORs, to give a signal on 1 of n lines to specify the amount and direction of the axial movement required, the movement of the hammer along the print line since the previous character printing being allowed for in the matrix connections. Alternatively the ORs may produce a sign bit and magnitude bits, the latter being set into a counter which is then decremented to zero to define the duration of the axial movement. The last and present columns may alternatively be compared by ANDing corresponding stages of two registers holding the two column indications respectively each as a single 1 bit among 0 bits, the "last" register being shifted in the appropriate direction until one of the ANDs produces an output, thus defining the duration of the axial movement, separate logic deriving the sign bit. Allowance for hammer shift (movement along the line) is done separately or the "last" register can be given an extra shift to allow for hammer shift. The required one of 12 rows on the drum is specified by specifying one of 2 halves of the drum and one of 6 rows within the half. The latter is compared with the similar quantity for the last character printed, by shifting the latter in the appropriate direction until correspondence is reached. Last and present "half" selection signals are compared also. Alternatively, rotational positioning of the drum may be controlled similarly to the first possibility above for axial positioning.

Title: Process for the manufacture of chlorinated hydrocarbon polymerisates
IPC: C08C19/14
Filed: 1937-05-07
Abstract: Polymerized butadiene-1.3 is chlorinated in the presence of solvents capable of dissolving both the starting material and the product. Suitable solvents are chloroform, ethylene chloride and chlorbenzene, but carbon tetrachloride is not suitable.  The products are rubber-like and are soluble in acetone and aromatic hydrocarbons. They are compatible with softeners such as dibutyl phthalate and tricresyl phosphate, with chlorinated diphenyl, natural and synthetic resins, and drying and non-drying oils. They may be separated from the reaction product by pouring into hot water and may be treated with an alkaline solution to remove loosely-bound chlorine.  They may be stabilized by adding an ethylene oxide derivative such as phenoxy-propene oxide.  In examples: (1) chlorine is passed into a solution of polymerized butadiene in chloroform and the product may be poured into methyl alcohol containing potassium hydroxide or by pouring an aqueous emulsion of the solution into a stream of hot water; (2) polymerized butadiene is chlorinated in ethylene chloride the product being treated as above; (3) a mixed polymer of butadiene and styrene is chlorinated in chloroform and treated as above.

Endless-band conveyers, material carried on.-Relates to the type of apparatus in which an endless chain of frames or plates moving in a serpentine course are tilted at each turn so as to deliver the material on to the returning stretch of the chain. The frames or plates 21 are carried by chains passing round driving- wheels mounted on transverse axles 5 at one end of the drying-chamber, round similar idle wheels at the other end, and round upper and lower wheels 16, 17 disposed outside the chamber. The wheels 16, 17 are mounted on bellcrank levers 19 acted upon by springs 20 to maintain the tension of the chain. The frames 21 are dragged along the upper stretch of the chains and at the first turn engage guides 26, Fig. 8, which keep them horizontal until the guides are cleared when the frames fall against springs 30. After the first turn the frames are pushed forward by the chains and at the following turns travel over curved guides 26, Fig. 7, which allow them to tilt gradually to discharge the material on to the lower runs of the chain and then guide them along the next stretch. The material is discharged as the lower run of the chain passes out of the chamber. Gases from a furnace pass through pipes 34 arranged under the drying chamber and may then escape into the chimney or may be directed through heating pipes 39 in the upper part of the chamber and are drawn by a fan through pipes 41 over which the drying air is forced by a fan 43 into the chamber. The air passes upwards over the pipes 34 and 39, and finally escapes at the outlet 45. Angleshaped guards are placed above the heating pipes to prevent material falling upon them.
