Abstract: 1,263,660. Ratchet clutches; change speed gear. FICHTEL & SACHS A.G. 7 Sept., 1970 [11 Sept., 1969], No. 42667/70. Headings F2C and F2D. In a centrifugally controlled ratchet clutch for a two-speed cycle hub gear wherein a pawl 8 carried by a driving ring 6 is biased by a spring 30 into engagement with rachet teeth 18 on a driven hub 4, a centrifugally controlled cam ring 13 pivoted on a pin 15 carried by the ring 6 and spaced from the clutch axis holds the pawl 8 disengaged from the ratchet teeth 18 below a predetermined speed of the ring 6 and releases the pawl above the predetermined speed. Centrifugal weights 10 pivoted on pins 9 carried by the ring 6 are biased inwardly by torsion springs 11. Pins 12 carried by the weights 10 engage slots 14 in the cam ring 13 so that outward movement of the weights 10, at the predetermined speed, pivots the cam ring 13 about the pin 15 to align a recess 16 in the ring 13 with the pawl 8 and thus permit clutch engagement. As shown in a two-speed cycle hub gear the driving ring 6 is fast with a ring gear 20. Planet pinions 21 on a carrier 22 fast with a driving sprocket 23 mesh a fixed sun gear 23 and the ring gear 20. For low ratio the hub 4 is driven from the planet carrier through a sleeve 5 and ratchet clutch 26, 27. When the ring 6 attains the predetermined speed the weights 10 move outwardly to engage the ratchet clutch 8, 18 whereupon the hub 4 is driven through the planet carrier 22, the planet pinions 21, ring gear 20 and ratchet clutch 8, 18 for overdrive, the ratchet clutch 26, 27 overrunning.

Patent GB-1592879-A (GB)
Title: Information folder construction and a method and apparatus for manufacturing the same
IPC: B31D1/02
Filed: 1977-10-18
Abstract: In order to produce rolls provided with information, for example directions for the use of pharmaceuticals, printed sheets (35) are wound from a stack sequentially onto a mandrel (75) to give tubular structures (35a), in each case the outer sheet edge being fixed by, for example, glue spots (127). The removal of these structures from the mandrel takes place automatically by means of a take-off device (104, 105). In order to fix the sheet on the mandrel, the latter can be connected to a vacuum device. For folded rolls (35c), the tubular structure (35a) is mechanically flattened to give a flat structure (35b) before cutting up into rolls. A folded roll consists of a strip (126) with fields delimited by fold lines perpendicular to the longitudinal edge. The last field during winding is an empty field which bears the glue spot (127). The penultimate field bears identification details. The other fields are provided with information in the manner of pages of a book. The roll holds together well and can be very easily opened for reading. The relatively simple device permits an extremely rapid, and therefore low-cost, production of such rolls. <IMAGE>

Abstract: 1,117,790. Extruding multi-layer films; extrusion dies. NATIONAL DISTILLERS & CHEMICAL CORP. 15 Oct., 1965 [23 Oct., 1964], No. 43716/65. Headings B5A and B5B. A laminating extrusion die for a three-layer film in which the side edges and either the inner layer or outer layer are of one polymer and the remaining layers or layer of a different polymer has feed channels 81, 82 for the surface layers in the die lips fed from a separate extruder from that feeding the central passage 31 for the central layer. The die orifice defined by the lips 60, 70 may be wider in the region occupied by the central layer than in the regions occupied by the surface layers so that in the extruded laminate the central layer projects at the longitudinal edges. Alternatively the outer layers may project beyond the central layer. These projecting portions only are engaged by the tenter hooks in the subsequent stretching operation and are subsequently trimmed. The trimmed material is thus of a single material only and can be returned directly to the process. The die lips are adjustable in the usual manner. The channels 81, 82 may be end fed or centrally fed (Figs. 1 and 11, not shown). The film layers may be of polyethylene and polypropylene.

Patent GB-452664-A (GB)
Abstract: 452,664. Washing granular materials. RUOSS, W., Batu Caves, Selangor, Federated Malay States. Feb. 26, 1935, No. 6191. [Class 82 (ii)] The chamber below the sieve of a jig washer is divided by a partition into two hutches and the pulsion and suction is produced by reciprocating a vibrator which is situated in an opening in the partition and is connected to the partition by a flexible member. In the preferred form the washer comprises a tank 10 below an inclined screen 28 which is supported on a grid 27 and along which flows the stream of material to be separated. A bed of hematite 30 may be placed on the screen, for example when washing tin ores. The tank 10 is divided into two or more compartments by a transverse wall or walls 12, each compartment being divided into two hutches by a partition 13. In an opening 14 in each partition 13 is situated a vibrator 15 which when reciprocated causes pulsion in one hutch and suction in the other. Water is supplied to the hutches by valved pipes leading from a main supply pipe 31, and one-way flap valves 33 are provided where the pipes enter the hutches. These valves close during the pulsion period and open during the suction period, thus diminishing the suction effect. Heavy particles passing through the screen into the hutches are discharged at outlets 34. In the form shown in Fig. 1, each vibrator consists of a circular hollow piston formed by two flat cones welded at the rims and having a central bush 19, the piston being attached to the partition 13 by a flexible annulus 16, e.g. of rubber, secured by iron clamping rings 17, 18. The buoyancy of the hollow piston 15 is adjusted to compensate for its weight in order to relieve the strain on the annulus 16. The pistons are secured by nuts 22 on a common piston rod 20 which is connected outside the tank 10 to a link 25 connected to the strap 24 of an eccentric 23, so that the vibrators reciprocate in unison. In the form shown in Fig. 3, the vibrator is a flap 35 which is hinged to the margin of the opening in the partition by a flexible strip 37, which may be of rubber or of thin spring steel, secured by clamping bars 38, 39. If a steel strip is used it may be protected by a rubber sheath. The flaps in the several partitions are connected together by links 40, the link at one end of the series being connected to the eccentric link 25. In a jig in which two or more vibrators are provided, as shown, the vibrators may be of different sizes or they may be of the same size and supported by flexible members of different depths, in order to produce different jigging conditions in successive pairs of hutches. Inclined-trough separation and jig separation may be combined by forming part of the trough as a screen and providing a tank with partitions and vibrators below the screen.

Title: Self locking joints for seats with hinged seat backs
IPC: A47C1/026
Filed: 1974-10-21
Abstract: 1445947 Seat back adjuster AUTOMOBILOVE ZAVODY NARODNI PODNIK 21 Oct 1974 45415/74 Heading A4J [Also in Division E2 ] In a pericycloidally geared self locking hinge for seat backs the drive-shaft is located centrally of the annulus 2 and is engaged with the spur 1 via a member 6, the curved end segments of which engage in recesses formed in the outer surface of the shaft. As may be seen from Fig. 1, annulus 2 is prevented from vertical displacement with respect to the wheel 1 by engagement of the teeth and is prevented from lateral displacement by the close fit of the member 6 on the shaft. As seen in Fig. 4 the recesses on the shaft are stepped, the portions separated by distance b being the close fit with member 6 shown in Fig. 1. This axial movement of the shaft will allow lateral freedom to the member 6 and hence allows the annulus to roll around it, thereby allowing rapid adjustment of the seat back angle. The shaft is axially returned to the locked position by coaxial spring acting on a knob secured thereto. Rotation of the knob effects fine adjustment in the manner usual with such gear systems. Specification 1372808 is referred to.
