Title: Improved change-over apparatus for operating electrically propelled vehicles with different voltages
IPC: B60L15/20
Filed: 1921-05-27
Abstract: 163,998. Akt.-Ges. Brown, Boveri, et Cie. May 28, 1920, [Convention date]. Systems operating on high and low voltage.- Vehicle installations operating both on high and low voltage supply are provided with a changeover switch electromagnetically locked in such a manner that it can only be moved to the proper side, according to the voltage which the installation is receiving. The locking arrangement, shown diagrammatically in the figure, consists of two toothed segments l, m, respectively co-operating with two locking pawls h, k, of which one is put out of action when the lower voltage is received from the trolley wire c, and the other when the higher voltage is received. One pawl being released, the switch drum z can then be moved to the proper side. An auxiliary contact u<1> cuts off current from both the pawl-releasing magnets when the switch has been moved to either side, and another pawl o retains it in the position set until either the driver closes a push switch e or a mechanical device s is actuated by a tappet or the like situated on the track. A further interlock may be provided between the change-over switch and the motor controller. The change-over contacts, which are not shown in the figure, may group motors in series and parallel, vary the fields, and make other necessary changes.

Title: Improvements relating to processes for bonding rubber to metal and to articles produced thereby
IPC: C08J5/12
Filed: 1951-06-21
Abstract: In bonding rubber to metal, a thin coating of an adherence layer, devoid of rubber, comprising a low molecular weight substance having an affinity for metals and a nitrogenous substance reactable therewith at raised temperature to form a resin is applied to clean metal, over the coating of adherence layer is applied a thin coating of an adhesive solution comprising rubber and a nitrogenous substance reactable at raised temperature with the substance having an affinity for metals to form a resin, the coatings on the metal are heated in an oxygen-containing gas, e.g. heated at 100-180 DEG C. in air of humidity not more than 80 per cent., to transform the non-rubber constituents of the coatings to an infusible, metal-adherent resin, a vulcanizable rubber compound is applied to the so-treated metal and is then vulcanized under pressure on the metal.  The substance having an affinity for metals may be a phenol or thiophenol in the molecule of which are at least two labile hydrogen atoms and a plurality of substituents formed by halogen atoms or sulphurated or nitrogenous groups, e.g. the monosulphide, disulphide or mercapto derivative of resorcinol, the reaction products of resorcinol with sulphur at 220-225 DEG C., produced, if desired, in the presence of hydroquinone; 1, 3-dimercaptobenzene; the reaction products of a phenol with thionyl chloride obtained in the presence of anhydrous aluminium chloride and freed from the aluminium choride and its transformation products; diresorcinol sulphoxide; resorcinol sulphonium chloride; resorcinol; p-nitrophenol; p-bromophenol. 4-chlororesorcinol.  The nitrogenous substance of the adherence layer may be a condensation product obtained by reacting ammonia or a primary amine with an aliphatic, aromatic or heterocyclic aldehyde, e.g. hexamethylene tetramine. the nitrogenous substance of the adhesive solution may be an N-substituted aldehydimine in the molecule of which are two azomethynic groups, R (- N=CH-R1)11, where n is 2 or more, R an organic radical of n valency, e.g. a polymethylenic chain of at least four terms, in which atoms of oxygen or sulphur may be inserted, and R1 is hydrogen, a monovalent olefinic radical, furyl or other monovalent radical having one furnace nucleus, such N-substituted aldehydimines being exemplified by monomeric difurfurylidenehexamethylenediamine, N-methylene - N1 - furfurylidene - hexamethylenediamine and difurfurylidene?p-phenylene-diamine.  The rubbers referred to are natural rubber, butadiene-styrene copolymers, butadiene-acrylonitrile copolymers, copolymers of butadiene or isoprene with isobutylene, polymers or copolymers of chlorobutadiene, thioplasts.  The adhesive solution does not necessarily contain the same rubber as that on which is based the rubber compound to be bonded; for heat-vulcanizable rubber compounds based on butadiene-styrene copolymers or thioplasts the adhesive solution may contain natural rubber.

Filed: 1966-04-04
Abstract: 1,093,189. Parking meters. DUNCAN PARKING METER CORPORATION, April 4, 1966, No. 14902/66. Heading G4V. In a parking meter wherein a coin carrier 30 is rotated to bring a pawl 64 into engagement with n ntehet wheel 68 for setting the time, means are provided to circumvent the use of a washer or disc thinner than the regular coin comprising a feeler adapted to engage the side of a coin or the like placed in a coin slot 32 in said carrier, so that the use of a washer or the like allows the feeler to extend into the coin slot and prevent the pawl from engaging the ratchet wheel. The coin carrier 30 having coin slots 32 is formed as an extension of a plate 28 manually rotatable by a shaft 26. Members 38, 40 and 42 are pivoted on a pin 44 carried by the plate 28. The member 40 is loaded by a spring 41 and carries a leaf spring 58, the ends of which engage members 38, 42, to urge them upwardly as seen in Fig. 5. In operation, the coin carrier is rotated whereby a coin rides on a surface 84, 86 or 88 until it strikes the surface 62 of the member 40 to pivot it anti-clockwise as illustrated. The members 38, 42 are lifted by the member 40 so that their edges 46 and 64 engage ratchet wheels 68 and 50 respectively. The timing mechanism is set by rotation of the ratchet wheel 68. Ratchet wheel 50 is fixed and prevents return movement of the coin carrier until the coin has been released. Fraud-preventing.-A plate 100 mounted between members 40 and 42 is restrained by pins 44 and 112 for sliding movement only. The plate is provided with feelers 108 urged towards the coin slots by a spring 116. A lug 122 on the member 40 co-operates with the edge 126 of the plate 100 whereby the feelers are normally positioned clear of the coin slots. When member 40 is pivoted by coin action, the plate is freed so that the feelers engage the side of the coin. If a washer or thin disc is used, the feelers enter the coin slots sufficiently to move the recess 134 in the plate 100 clear of the detent 76 in the member 42. The detent strikes the edge 132 of the plate, whereby engagement of the member 42 with the ratchet wheel 68 is prevented.
