Title: Improvements in conveyors
IPC: B65G47/50
Filed: 1922-07-31
Abstract: 183,855. Nordstr÷m, L. July 30, 1921, [Convention date]. Discharging and feeding devices for endlesschain conveyers.-Planks carried by hooks depending from two or more parallel chains are discharged automatically at any desired one of a series of stations by mechanism set by the attendant immediately after a plank has been placed on the conveyer. At each station pivoted arms 60, Fig. 13, are provided which normally are held in position a by a counterweight 58 but are moved into position b to remove a plank from the hooks 16 when the cable 56 connecting the bell-crank lever 57 to a pivoted arm 40 is actuated by the movement of the latter. A series of arms 40 corresponding to the number of stations is provided, and each arm is rocked by radially-movable teeth 21 carried by a corresponding disc 20 when any tooth is in its extended position. Normally the teeth are retracted and in this position a pin 28 on each tooth moves in the inner of two grooves 27 formed in a non-rotatable annular disc 23 which bears against the face of the disc 20. A rocking member 29 mounted on the disc 23 has a projection which in one extreme position of the member deflects the pins from the inner to the outer groove, thereby extending the teeth. As soon as one pin has been deflected the projection returns to its normal position in which it does not obstruct the movement of the pins in the inner groove. The member 29 is rocked by an arm 31 on a disc 32, which is mounted on the hub of the - disc 20 and turned by the engagement of an arm 34 with pins 33. The arm 34 is attached to a lever 36. The shaft 19 of the discs 20 is driven at a rate such that a tooth is moved through the distance separating adjacent teeth in the same time as a hook 16 is moved through the distance separating adjacent hooks. The rocking members 29 are attached to the discs 23 at such positions that, for the disc controlling the nth station, the corresponding disc 20 turns through an angle corresponding to n teeth before the extended tooth engages the lever 40. Means are provided for returning the lever 36 and disc 32 to initial position as soon as a tooth has been extended, and for moving a tooth inwards as soon as it has actuated the lever 40. The planks are delivered to the hooks from a table 8, Fig. 9, by rotating angle arms 9.

Patent GB-785732-A (GB)
Title: Di-pyridyl derivatives
Inventor: FIELDEN RICHARD JAMES
IPC: C07J1/00
Filed: 1955-07-20
Abstract: The invention comprises new salts of formula <FORM:0785732/IV (a)/1> in which X stands for an anionic radical, such as chloride, bromide, iodide and p-toluenesulphonate radicals.  They may be prepared by heating a ,a 1-dipyridyl with an ethylene glycol di-ester.  The reaction may be carried out in the presence of an inert solvent or diluent, for example nitrobenzene or b -ethoxyethanol.  Certain of the new compounds may also be obtained by reacting a salt of formula <FORM:0785732/IV (a)/2> (in which Y is an anionic radical) with a salt derived from an anionic radical X.  For example, a compound of the above formula in which Y stands for bromine can be converted into an iodide or chloride by treatment with sodium iodide or silver chloride respectively.  The new compounds possess herbicidal properties and may be used as herbicides in the form of aqueous solutions to which may be added wetting agents and/or humectants and agents having adhering properties or in the form of powders when mixed with inert pulverulent diluents.  In the examples: (a) 2,21-dipyridyl is heated with ethylene dibromide to give the quaternary bromide monohydrate; (b) the dibromide obtained in (a) is treated with sodium iodide solution to give the quaternary iodide; (c) the product of (a) is treated with silver chloride solution to give the quaternary chloride; and (d) 2,21-dipyridyl is heated with ethylene bis-p-toluenesulphonate to give the quaternary p-toluene sulphonate.ALSO:Quaternary salts of formula <FORM:0785732/VI/1> in which X is an anionic radical such as chloride, bromide, iodide or p-toluene-sulphonate radical have herbicidal properties and may be used in herbicidal compositions.  The compositions may be liquid compositions, e.g. aqueous solutions of these salts.  These liquid compositions may advantageously contain wetting agents and/or humectants.  Suitable wetting agents are, for example, alkali metal salts of dinaphthyl methane disulphonic acids or of long-chain aliphatic sulphates, e.g. sodium lauryl sulphate, and condensation products of ethylene oxide with an alkyl phenol such as octylcresol. The humectant may be, for example, calcium chloride, glycerol, ethylene glycol or a water-soluble polyethylene glycol.  These liquid compositions may also contain agents which improve the adhering properties to the plant, e.g. sodium carboxymethylcellulose and ammonium polymethacrylate.  The herbicidal compositions may also be in the form of solid compositions in which the new quaternary salts are mixed with inert pulverulent diluents, e.g. talc, china clay, gypsum, basic slag, kieselguhr or bentonite.  In the examples herbicidal compositions are made by mixing 2,21-dipyridyl ethylene dibromide, water and a polyethyleneoxy alkylphenol; (b) dissolving 2,21-dipyridyl ethylene dibromide in water; and (c) mixing 2,21-dipyridyl ethylene dibromide with china clay.

Title: Model train sound simulator
IPC: A63H19/14
Filed: 1974-05-13
Abstract: 1436814 Toy railway vehicles LOUIS MARX & CO Inc 13 May 1974 [23 May 1973] 21060/74 Heading A6S A model train unit e.g. a tender car (Fig. 2) incorporates a sound simulator assembly comprising a wheel 20 mounted to the unit and rotatably disposed against an energised track 13, and a sound generator coupled to the wheel, the generator producing one audio signal when a portion 26 of the wheel is in contact with the track and a second audio signal when a second portion 27 of the wheel is in contact with the track. The tender car includes an electrically conductive chassis 17 which is electrically coupled to rails 12, 14 by the supporting wheel assemblies 16. The chassis supports a carriage moulding 18 wherein an electronic noise generating circuit 21 and a loudspeaker 22 are housed. The wheel 20 comprises two semi-circular conductors 26, 27 supported by an insulating disc 28, the conductors each having cylindrical surfaces 26', (27') for contact with the rail 13. The conductors 26, 27 are electrically coupled through a resistor 30, while conductor 26 is secured to the conductive axle 29 of the wheel 20. The axle 29 is supported in channel guides 19' of an insulating wheel support assembly 19, and is connected to the noise generating circuit 21 through a conductive bracket 24 and a wire 31. A coil spring 33 which engages the conductive bracket 24 serves to force the wheel 20 into engagement with the rail 13. A wire 32 couples the noise generating circuit 21 to the chassis 17 at a mounting rivet 23. A transformer is connected across the outside rail 12 and the centre rail 13. Thus when the conductor 26 is in contact with the centre rail 13, a closed series circuit is formed including the conductor 26, the axle 29, the bracket 24, the wire 31, the noise generating circuit 21, the wire 32, the rivet 23, the chassis 17, and the outside rail 12. When the second conductor 27 is in contact with the centre rail 13, the series circuit includes the conductor 27 and the resistor 30 between the rail 13 and the conductor 26. The circuit 21 includes a white noise generator and an amplifier, the latter being connected to the loudspeaker 22 to provide a hissing sound. When the resistor 30 is in the series circuit the voltage applied to the circuit 21 is reduced to provide a lower level hissing sound. As the wheel 20 rolls on the track 13, alternate high and low level hissing sounds are therefore generated to simulate the puffing sound of a locomotive at a rate proportional to the speed of the train. The invention may also be utilised on model train units that operate on two-rail tracks.
