Title: Motor vehicle transmission system
IPC: F16D43/06
Filed: 1963-10-02
Abstract: In a motor vehicle transmission having a centrifugal clutch or fluid coupling and a change speed gear between an engine and the road wheels, means responsive to gear lever position are provided for preventing the transmission of adequate power to drive the road wheels when an attempt is made to drive the vehicle forward from rest in at least one high gear. The means may prevent engagement of the centrifugal friction clutch or may empty the fluid coupling when the vehicle is started from rest in a ratio other than first or second gear. In Fig. 1 engagement of a centrifugal clutch having a clutch plate 16 which is normally clamped between a flywheel 11 and presser plate 22 on outward movement of centrifugal masses 26, is prevented when starting from rest in a ratio other than first or second gear by pawls 44 which are moved into the path of the masses 26. The pawls 44 are pivoted at 45 to a plate 46 which is rotatable on, and axially movable with, a sleeve 51 connected to a shift rod 52 of the gear. The pawls 44 are thus moved to the position shown whenever a ratio higher than first or second gear is engaged. During ratio shift whilst the vehicle is moving the engine speed is sufficient to retain the masses 26 in their outward position in which they abut stops 37 and the clutch is disengaged manually through a lever 38, thrust bearing 39 and linkage 40, 41 to move right the mass carrier 25 and permit springs 32 to release the clutch. When the vehicle comes to rest in high gear the masses 26 move inward, the pawls 44 pivoting inward against the bias of springs 53 until the masses are in the innermost position shown whereupon the pawls move to the position shown and prevent clutch re-engagement whilst the vehicle is in high gear. The mass carrier 25 is positioned relative to the casing 17 by springs 30 and the compression of the clutch release springs 32 may be adjusted by nuts 33. In Fig. 6 a fluid coupling 131 is normally maintained full by supplying liquid from a pump 139 to the coupling and through a line 137 to a valve 135 which in the position shown closes a drawn line 136. When the vehicle comes to rest in high gear switches 72, 73 are closed to energize a solenoid 149 which moves right a valve spool 150 to cut the pump supply to line 137 which is opened to vent at 145 whereupon the valve spool 147 moves up and and the coupling is emptied through line 136. When low gear is engaged the switch 72 opens causing the valve spool 150 to move left and permit the coupling to be refilled.

Patent ES-349752-A1 (ES)
Title: Improved pallet construction
IPC: B32B27/00
Filed: 1968-01-25
Abstract: A pallet formed from a laminated panel comprises a core, e.g. of balsa or plywood, and two facing layers, e.g. of aluminium or phenolic resin, a marginal portion of the panel having been compressed so that the core is thinner and denser in this portion than elsewhere. An edge member extends along the marginal portion. Both faces of the panel may be indented when compressing the marginal portion, Fig. 2, and the edge member may be U-sectioned and metallic and may embrace this portion and be adhered thereto. A tapering transition zone 31 connects the thinner and thicker portions of the panel. Only one surface of the panel may be indented during compression, Fig. 3. This Figure shows an edging strip riveted at 43 to the panel. Two panels of the form shown in Fig. 2, may be joined in edge-to-edge co-planar relation by an H-sectioned member, Fig. 4 (not shown). Alternatively, two such panels may be joined in edge-to-edge relation by a suitably formed member, Fig. 14 (not shown), so that the panels are perpendicular or at any other angle to each other. The panel is compressed, to form the marginal portion of reduced thickness, between two suitably shaped dies Figs. 5, 6, 8, 10 and 11 (not shown). The part of the operative surface of each die which will form the tapered transistion zone may be tapered or rounded so as not to puncture the facing sheets. A block positioned between the dies limits the compressing movement thereof. One of the dies has a planar operative surface if only one face of the laminate is to be indented. The dies may be formed with passages for steam, hot water or electric heating coils in order that local heating of the panel may be effected prior to compression. When an indented portion is required to have a surface parallel to that of the rest of the panel, the corresponding die is shaped so as to effect more compression adjacent the tapering transition zone than at the edge of the panel on moving the dies apart, the compressed portion expands differentially to give the required parallel surfaces. Alternatively, the dies may be shaped so that the thickness of the compressed portion decreases towards the edge of the panel.

Patent ES-362463-A1 (ES)
Title: Fastener manufacture
IPC: B21K1/44
Filed: 1968-12-21
Abstract: A machine for making self-locking threaded fasteners 68 comprises a rotatable work-holder or dial member 14 provided with means 62 for holding fasteners 68 at uniform spacings, means for step-by-step rotation of the workholder, and a plurality of work heads 16-20 disposed around the work-holder, each work head comprising a tool holder 114 reciprocable between steps in the rotation of the work-holder. The threaded fasteners 68 are fed by gravity down a ramp 82 at a feeding station and as the dial member rotates through its next step, a spring loaded roller 76 moves radially outwardly along the camming surface of a cam 80 thereby pivoting an arm 72 to hold the fastener in the work-holder 62, Fig. 5. The work heads 16, 17 perform first and second coining operations to form an opening in the workpiece and the work head 18 reforms the threads on the workpiece. The head 19 inserts friction material into the coined opening and the head 20 reforms the threads on the workpiece and on the inserted material. The work head 16 is driven by an electric motor (22) via a belt and pulley drive and an indexing mechanism (42), constant rotation of which causes step-by-step rotation of the dial member 14, Fig. 1 (not shown). The drive to the head 16 rotates a planet gear 54, which meshes with a ring gear 56, Fig. 4. The other heads 17- 20 are also provided with planet gears 54 similarly meshing with the gear 56, and the operating mechanism in each head 16-20 is identical. The gear 54 is locked to a shaft 94, which is provided with an eccentric portion 104. An anvil 110 bears on the portion 104 and is threadably received in a cylindrical member 106. A retainer rod 112 is secured at one end to the anvil and at the other end to a tool holder assembly 114. The rod 112 is biased towards the portion 104 by a spring assembly which bears on a stepped portion of the rod and on fixed guide pins 118. The anvil is formed with a gear portion 130, which meshes with a gear 132, and rotation of the latter causes relative rotation between the anvil and the member 106, thereby adjusting the position of the tool holder. After the final thread reforming operation by the head 20, the fastener is indexed to the next station, where the cam 80 pivots the arm 72 to release the fastener. A blast of air from a nozzle 81 forces the fastener into a receptacle below an opening 83.

Patent ES-367016-A1 (ES)
Title: Phenolic resins
IPC: C08J9/14
Filed: 1969-05-09
Abstract: This invention pertains to the manufacture of foams from phenolic resins and to the foams so produced. Such foams are made by mixing a blowing agent with the resin in a soft or fluid state, adding a hardening catalyst which produces an exothermic reaction of sufficient intensity to vaporize the blowing agent and form the foam, and hardening the foam. In such processes a strong acid is usually employed to generate the exothermic reaction but its action is accompanied by undesirable side effects, e.g. during the use of the foams as insulators for a metal object the residual acid in the resin may produce corrosion. To reduce that objection the resin has been processed to remove or neutralize the acid, or both, the attempt being to eliminate the large part of the acid and neutralize the residue. Such processing is difficult and imperfect. According to the invention Resorcinol is included in the composition of the phenolic resin which is to be foamed by acid catalysts. The presence of the Resorcinol is productive of several advantages including improvement of electrical properties, color stability and reduction of corrosive tendencies.
