Title: Improvements in or relating to money changers
IPC: G07F5/24
Filed: 1961-11-01
Abstract: 957,459. Coin delivery apparatus. M. HARTING, [trading as WILHELM HARTING WERK FUR ELEKTROTECHNIK UND MECHANIK]. Nov. 1,1961 [Oct. 16,1961],No. 39048/61. Heading G4X. A change-giving device comprises a number of coin or token containers 2 arranged in a closed pattern, for example, a circular or oval pattern, and a coin ejector 13 movable beneath the containers by means of a rotatable plate 3 or guide rail, belt or chain, the ejector being carried by the armature 14 of a solenoid energizable to bring the ejector into position to engage the lowermost coin in a container or a coin lying above such coin. The solenoid is energized through spring contacts 16, 16<SP>1</SP> which bear on a ring contact 18 and segmental contacts 18<SP>1</SP> corresponding to the number of containers, the contacts 18<SP>1</SP> being selectively coupled in circuit so that any desired combination of coins can be discharged during a complete revolution of the plate 3 by a motor 4 and reduction gear 24. The head 20 of the ejector passes through a channel 12 in an inclined coin-supporting member 10 to engage the lowermost coin and move it so as to press back two limbs of a spring, the limbs subsequently closing behind the coin to eject it into a tray 23 ahead of the ejector. The sloping undersurface of the member 10 is engaged by a projection 21 on the ejector so that the latter does not have to raise the coin stack and also so that the ejector is positively pushed down if the armature 14 should jam. The solenoid may be pivotally mounted on a spring-loaded hinge so that it can yield to pass a jammed coin container. The containers 2 fit in sockets 5 which are of conical formation so that one size of container may be used for more than one size of coin. The supports 10 form part of the sockets and may be varied in thickness so that two or more coins are simultaneously discharged from one container The containers are held in their sockets by a spring-loaded closure plate.

At the latter position the cross-bar leaves the surface of the drum, due to the displacement of the axes 14, 19, and a pair of gear-wheels 22, 22<SP>1</SP> meshing with gears 18, 18<SP>1</SP> and connected to springs 25 pass through the "dead centre" position (see Fig. 2d) so that the spring tension imparts a (fast) rotary motion to the gears 22, 22<SP>1</SP> which return the cross-bar rapidly to the position 0. In operation, "paper" 10 (for recording a play-back) is positioned under the cross-bar at position 0 and the cross-bar and paper are then pushed to position I (see Figs. 2a and 2b) when it is gripped between the cross-bar and the drum. The operation then continues as shown in Figs. 2c and 2d at which, when the cross-bar leaves the surface of the drum and is returned rapidly to position 0 the paper supported by roller 27 is deposited on a table 32. During the rotation of the drum the paper is also retained by a comb 30 and is scanned by a writing or reading element moving parallel to the axis of the drum as shown symbolically at 31. Fig. 3 shows features of the construction.

Abstract: 831,343. Crimping yarns; thread guides. TEXTURA A.G Dec. 27. 1956 [Dec. 30. 1955], No. 39266/56. Classes 120(2) and 120(3) In a process of compression-crimping in which individually-spaced continuous filament yarns are continuously fed by a pair of counter-rotating members into a container, entanglement of yarns is prevented by an electrostatic field generated adjacent the members. In the apparatus shown in Figs. 1 and 2, a guide bar 10 maintains yarns 11 in separate and parallel relation as they pass through an adjustable, perforated guide bar 12 and a dividing device 38 of crimping apparatus 15: relatively adjustable, spring-loaded rollers 28 and 29, driven from a motor 32 through belt 33, pulleys 25 and 34, gears 36, 36<SP>1</SP>, 35, 35<SP>1</SP>, feed the yarns into a housing 44 wherein the yarns are crimped and emerge to descend, as a web in relaxed condition, into a box 49 which is transferred to an oven 51 for heat-setting the crimped material e.g. by use of steam, infra-red rays, heating coils, ultrasonic or high frequency means, for periods up to three hours and temperatures up to 500F. and pressure (steam) up to 50 lbs. sq. inch. The yarns are then separated from the web and wound singly or as multiplies in preparation for twisting, winding and/or weaving or 'Knitting. Electrostatic charge eliminators 45, 46, 47, insulated from the apparatus framework, each comprise a straight bar of circular cross-section having a series of projections thereon and are connected to a source of electricity so that they are charged to dispel electrostatic charge tending to develop on the yarns as a result of their frictional contact with parts of the apparatus. As shown in Figs. 3 and 5, the divider 38 comprises side and end members 39, 40, and 41, 41a supporting metal strips 42 defining slots 43 through which the yarns pass and are segregated, if necessary, by filler plates 43a. Divider 38 may be replaced by a unit consisting of plates extending over roller 28 or 29 and comprising half the shape shown in Fig. 5.

Abstract: 1450147 Variable-ratio gearing FIZIKO ENERGETICHE INST AKAD NAUK LATVII SSR 28 Aug 1973 40411/73 Heading F2D [Also in Division H2] Driving apparatus comprises an induction motor, the stator windings of which are selectively connectible in star or delta configurations, a gear unit connected with the output of the motor and having a relatively high (e.g. unity) and a relatively low (step-down) gear ratio, and two-state control means connected with both the windings and the gear unit to connect the windings in star configuration and to select the lower gear ratio, and to connect the windings in delta configuration and to select the higher gear ratio when in the other state. An input shaft 4 is connected with an output 7 via a differential system 10. A field winding 19 encircles the assembly which is placed in housing 25. A pole holder 16 having a plurality of poles disposed in a diamagnetic alloy lies within the field winding as shown and is connected to one of the elements of the differential 10. An armature 13 lies in the member 16 and is connected to the input shaft 4 and an overrunning device 22 is connected between the device 16 and housing 25. In operation with no excitation applied to the field winding, the output shaft 7 via the gears 10 will tend to turn in the opposite direction to that of the input shaft 4. The overrunning device will cause the output shaft 7 to thrust against the housing 25 with the result that the system will operate as a planetary reduction gear. With excitation applied to the field winding, the electromagnetic interaction between the armature 13 and the member 16 will cause the input and output shafts to rotate in unison and the system provides a gear ratio of approximately unity. Alternative embodiments of the gear system are illustrated schematically in Figs. 3, 4 (not shown).

Title: Improvements in or relating to resilient tapes and to a method of making resilient tapes
IPC: B29C70/00
Filed: 1958-12-18
Abstract: 909,702. Elastic fabrics; laminates; coated fabrics. REGGIANI, P. Dec. 18, 1958 [Dec. 20, 1957], No. 40898/58. Drawings to Specification. Class 140. A resilient tape includes a textile structure having interstices which are filled with rubber compound and at least two reinforcing warp threads extending along the tape, the structure consisting of an open-mesh fabric which, on account of the manner in which the threads are interconnected, has a high extensibility in the longitudinal direction. The rubber compound is a vulcanizable composition of natural rubber, synthetic rubber or any other suitable elastomer capable of vulcanization, and being elastic when vulcanized. The reinforcing warp threads are parallel and have a tensile strength low enough to permit rupture thereof by a load less than that required to rupture the other threads of the fabric, which other threads still form a coherent fabric after rupture of the reinforcing threads. The reinforcing threads serve to prevent stretching of the fabric and consequent distortion of the interstices during the filling of the interstices with rubber, e.g. between calender rollers, but permit the fabric to stretch after the rubber compound has been vulcanized and they have been broken. The tape may be covered on one or both sides, e.g. in another calender, with a layer of rubber compound which is subsequently vulcanized. The fabric may be knitted or may be a net or other woven fabric of any of the special weaves listed in the Specification, and may be of natural or synthetic material. The reinforcing threads may be provided during the knitting or weaving operation, or may be provided, e.g. by sewing, after knitting or weaving, but before rubberizing. The resilient material may be made in great widths and subsequently cut to desired lengths and widths. In another embodiment, the fabric is sandwiched between two layers of rubber, and heat and pressure applied so that the rubber penetrates into the interstices of the fabric and is vulcanized. Specification 707,433 is referred to.

In a rectilinear cotton comb the shaft 80 for oscillating the moving nipper 81 is driven from the constant speed cylinder shaft 51 through a linkage which allows shaft 51 to be driven at a higher speed and yet provide the same period for moving the nipper away from the cylinder as is provided by a normal eccentric drive. In addition the nipper moves slowly when close to the cylinder. The linkage comprises, see also Fig. 2, not shown, an arm 112 eccentrically mounted on a disc 100 on shaft 51, and arm 117 linking arm 114 to an arm 119 secured on shaft 80; in addition arm 112 is pivoted to a link 115 pivoted on a pin 116 fixedly mounted between the shafts 51 and 80. The motion of the nipper is illustrated in Fig. 5 (not shown) and compared with the motion imparted to the nipper by the known linkages of Figs. 3 and 4 (not shown). The oscillating rotation of the detaching rollers 38, 43 is produced by compounding the motion from a pair of eccentrics 10, 15 in a pivoted lever linkage, using the componded motion to oscillate a lever 27 to move a planet gear 29 about its sun 30, driving planet 29 at a constant speed derived from the cylinder driving shaft 51 and using the resultant motion on the shaft 31 of sun gear 30 to drive the rollers. The resultant motion as shown in Figs. 8, 9, not shown, is stated, to allow a higher speed of the combing cylinder without imparing the quality of the piecing up.
