Filed: 1937-07-21
Abstract: 492,783. Cables. ETABLISSEMENTS J. CHOMAT ET F. DANSARD. July 21, 1937, No. 20208. Convention date, Jan. 5. [Class 36] An extensible cable comprises a conductor-supporting carrier of inextensible material and an elastic cord which are connected together at their ends and are held in contact with each other at a number of points along their lengths so that the elastic cord tends to draw the carrier into pleats. The connections between the elastic cord and carrier are such that the two may be readily separated to permit renewal of the elastic cord. The elastic cord may be of rubber, or may consist of a metallic spring. In the construction shown in Figs. 1 and 5, insulated conductors 1 are enclosed in a braided or woven carrier 2 which is provided along its length, preferably along its centre line, with regularly spaced slits 3. The strip is folded between the slits so that the latter are in line and an elastic cord 4, which consists of rubber strands enclosed in an extensible woven or braided sheath, is passed through the slits, the ends of the cord being then secured to the carrier by bindings 6. The length or the cord 4 is preferably such that the folds of the carrier are pressed one against the other when the cord is unstretched.

Title: Methods and circuit arrangements for generating pure continuous electric currents by means of machines
IPC: H02K23/02
Filed: 1920-07-09
Abstract: 148,401. Lorenz Akt.-Ges., C., and Schmidt, K. Feb. 13, 1919, [Convention date]. Converting alternating and direct currents. - Pure continuous current is obtained from a dynamo-electric machine by generating in the supply circuit a voltage that counteracts the undesired alternating currents impressed on this circuit by the machine. In the arrangement shown in Fig. 3, a transformer is used, whose primary winding S1 is connected across the terminals of the machine D, the secondary winding S2 being connected in circuit with the load V, which may be a microphone. A battery Z of primary or secondary cells or of polarization cells is connected in series with the winding S1, the voltage of the battery being equal but opposite to the continuous current voltage of the machine, so that only the alternating components of the current pass through the winding S1. The voltage induced in the winding S2 counteracts the alternating voltage directly impressed on this winding, so that pure continuous current is supplied to the load. An adjustable inductance may be inserted in series with the battery, or the battery and inductance may be replaced by a variable ohmic resistance. An auto-transformer may be used instead of a transformer with two windings. In order to compensate for the drop of voltage due to the ohmic resistance of the battery Z, an adjustable choking-coil r may be coupled with the field of the transformer and inserted in the supply circuit, as shown in Fig. 4. The coil r is adjusted until the disturbing alternating currents in the load V sink to zero, which may be ascertained by connecting a telephone receiver t across a portion of the load. The magnetic circuit of the transformer is preferably provided with an sir gap in order to limit its saturation by the continuous current. The Specification as open to inspection under Sect. 91 (3 )(a) states that a machine which generates the necessary counter-voltage may be employed instead of a transformer. This subjectmatter does not appear in the Specification as accepted.
Patent GB-805017-A (GB)
Title: Improvements in method and apparatus for controlling tension in web material
IPC: D06C29/00
Filed: 1956-07-02
Abstract: 805,017. Feeding webs. FIRESTONE TIRE & RUBBER CO. July 2, 1956 [Sept. 21, 1955], No. 20391/56. Class 100(1) An apparatus for varying the longitudinal tension of a continuously moving web of material, especially nylon material. comprises two spaced groups of rollers, at least one of the groups comprising a plurality of rollers associated in pairs, with each pair of rollers in this group being driven at a speed substantially different from that of the preceding pair of rollers in the group, the differences in speed in each group all being either increases or all decreases. As shown, nylon fabric 14. used for manufacturing tyres, is withdrawn from a supply roll 15 and passes through a splicing apparatus 17 and rollers 18 into a device 19 which accumulates sufficient material to permit splices to be made without stopping the apparatus. The fabric passes through a liquid tank 20 and squeeze rollers which remove excess liquid before passage through a drying apparatus 22. A group 23 of rollers impart longitudinal tension to the fabric since pairs of rollers, 1, 1a; 2, 2a, and 3, 3a are driven progressively faster. For example, each successive pair of rollers may impart a stretch of about 1.5 per cent to 2 per cent. The fabric then passes through a heating tower 24 which stretches the fabric further; the fabric is withdrawn by a group 25 of rollers. The group 25 comprises a single roller 5 and pairs of rollers 6, 6a; 7 and 7a which are driven at progressively decreasing peripheral speeds to reduce the stretch. ' The fabric then passes through a further heating tower 26 and a further group 27 of rollers. The group 27 comprises water cooled rollers 12 and 13, a single roller 8, and pairs of rollers 9 and 9a; 10 and 10a, and 11, 11a, the pair of rollers being driven at decreasing speed thus reducing the fabric tension. To reduce slip, damage to the fabric, and roller wear the fabric may have a large wrap round the rollers, e.g., between 162 and 196 degrees for the end rollers of a group and about 210 degrees for the inner rollers in a group. The fabric passes through an accumulator 28 before being rewound into a roll 2.

Abstract: 531,970. Distilling water. YSSELMUIDEN, A. H. July 14, 1939, No. 20530. Convention date, July 16, 1938. [Class 32] In apparatus for distilling water by using the neat generated by an internal combustion engine the water is circulated through an evaporator and a heat exchanger through which the cooling medium for the engine is circulated. The cooling medium is circulated through the engine A and the heat exchanger N while the water to be distilled is circulated through the exchanger N and the evaporator B by a pump C which maintains a higher pressure in the exchanger than in the evaporator. The steam formed is condensed in a condenser D maintained under reduced pressure by a pump G and the condensate is sterilized by passage through a coil Q heated by exhaust gases from the engine to a collecting chamber W, passing thence through a cooler S to a receiver F. Make-up water is fed through the cooler S and condenser D to the circuit the amount being controlled by a valve K operated by a float L; excess water is discharged by pump J. In a modification the cooling medium from the engine is heated by the exhaust gases before entering the heat exchanger N. The heat exchanger and evaporator may be combined in one unit. The Specification as open to inspection under Sect. 91 of the Acts describes apparatus in which the water to be evaporated is circulated directly through the cooling chambers of the engine. This subject-matter does not appear in the Specification as accepted.

[Class 130.] Tobacco is supplied to a belt 23 located in a hopper containing a carding-drum by a conveyer belt 20 carrying removable partitions 36 between fixed side walls 19. Projections 38 on the partitions 36 extend over the edges of the walls 19. As the partitions approach the belt 23, the projections 38 follow a cam track 41, 42 on the walls 19 and raise the partitions from the belt, thus allowing the tobacco to pass onwards. The operator then removes the partition and replaces it at the rear of the belt and fills in the space between two partitions with tobacco up to level 31 on the wall 19. To level and compress the tobacco charge as it enters the hopper, a roller 50 is adjustably mounted on the wall 12. The belt 20 is driven through reduction gearing from the main drive of the machine.
