Title: Indexing piston for an internal combustion engine
IPC: F16J1/24
Filed: 1968-10-25
Abstract: A piston and connecting-rod assembly for an internal combustion engine comprises an indexing member 81, Fig. 1, coupled to the rod 5 so that pivotal oscillation of the rod relative to the piston 1 produces rotary oscillation of the member, co-operating friction surfaces on the member and piston respectively and means whereby, in operation, a force derived from a source other than the pivotal movement of the rod is applied intermittently to frictionally engage and release the friction surfaces in phase with reciprocating movements of the piston which is thereby progressively rotated about its axis. The rod 5 has a ball end 4 housed in a spherical bearing 2, 3 and carrying an inclined pin 14 whose ends engage between two pairs of lugs 13 on the indexing member 81. A thrust member 10 is located with the member 81 with axial clearance in a recess in a ring 7 secured to the piston by bolts 8. A screw 12 threaded in the ring 7 projects into a groove 11 in the member 10. In operation, when the inertia force of the member 10 acts to clamp the member 81 against the ring 7 the piston rotates with member 81. When the inertia force acts in the opposite direction member 81 rotates freely in the ring 7. In a modification. Fig. 2 (not shown) the inertia effect of the thrust member (27) is augmented by the inertia effect of the cooling oil in the piston head cavity (20) which communicates through bores (19) with a groove (18) slidably housing the thrust member. In a further modification. Fig. 3, a thrust member 37 is urged against the indexing member 36 by the pressure of lubricating oil supplied through bores 42, 43 in the rod 39 and a groove 45 and a bore 49 in the piston 31 to an annular groove 49 slidably housing the member 37 the flow of oil being controlled by the pivotal movement of the rod 39. In the modification shown in Fig. 5, the indexing member 66 has a spherical bearing surface 67 for the ball head 62 and a conical friction surface 68 co-operating with a friction surface 69 on a part 70 secured to the piston 61. The friction surfaces 68, 69 are loaded by the inertia of the piston when it is in the vicinity of top dead centre. In another modification, Fig. 7 (not shown), the inclined pin (86) has only one end engaging a notch (87) in the indexing member (88) which has a conical friction surface (89) co-operating with a complementary surface (90) in a member (84) and a thrust bearing (91) is interposed between the member (88) and the piston (81).

Title: Roller testing stand for motor vehicles
IPC: G01M17/007
Filed: 1968-11-06
Abstract: The brakes of a vehicle are tested by locating the front (or rear) wheels on a roller stand, driving the left and right hand roller pairs by independent electric motors and measuring the speed of rotation of the rollers when the brakes are applied, the differential of this signal giving the braking force and the integral of this signal giving the braking distance. Each roller is coupled to a photo-electric tachogenerator whose output frequency is converted at 15a-15d Fig. 3 to a corresponding voltage speed signal U v . The signals from the rollers of each pair are added at 18a, 18b and may be fed to speed indicators. When the brakes are applied to reduce the speed, the differentials of the speed are obtained at 19a, 19b, the resulting signals U k1 , U kr representing the power developed by the individual wheels. The power supplied by the driving motors 5, 6 is measured by current transformers 20a, 20b, phase-sensitive rectifers 21a, 21b and networks 22a, 22b where the motor losses are subtracted, the resultant signals being added at 23a, 23b to the wheel power signals to obtain at 26a, 26b indications of the brake power at each wheel. Each signal may be multiplied by a factor representing the mass of the wheel and roller system, to determine the decelerating effect of the brakes. The maximum value of the signals is stored on capacitors 28a, 28b and indicated at 29a, 29b. An overload safety device switches off the motors 5, 6 when the brake power signals at 26a, 26b exceed a predetermined value. The distance travelled after braking and switching off motors 5, 6, as measured by integrating the speed signals, is inversely proportional to the average brake power.

Title: Novel cycloalkenone esters
IPC: C07C45/68
Filed: 1970-03-09
Abstract: The invention comprises cycloalkenone esters of the formula in which R is a hydrogen atom or an alkyl, alkenyl, or alkynyl group having up to 8 carbon atoms, R 3 is an alkyl group having up to 8 carbon atoms and n is 1 or 2, except that when n is 2, R is not hydrogen or methyl. These esters can be obtained by reacting an enol ether of general formula in alkaline, anhydrous reaction medium with a compound of formula CH 2 (COOR 2 ) 2 , in which R 2 is an alkyl group having up to 8 carbon atoms. The preferred alkaline anhydrous medium is a solution of an alkali metal alcoholate in the alcohol and when such an alcoholate is used the group R 3 in the product will correspond to the alkyl radical of the alcohol due to transesteriflcation. The esters formed may be used as intermediates in the production of odorants. For example [2-(21-pentynyl)-3-keto-1-cyclopenten-]-yl acetic acid methyl ester may be catalytically hydrogenated using a Lindlar catalyst and subsequently hydrogenated using lithium in ammonia to give methyl jasmonate, i.e. [2-(21-pentenyl)-3-keto-1-cyclopent-]-yl acetic acid methyl ester. [2-Pentyl-3-keto-1-cyclopent-]-yl acetic acid methyl ester may be obtained by hydrogenation from [2-pentyl-3-keto- 1-cyclopenten-]-yl acetic acid methyl ester. The latter ester may also be saponified and product decarboxylated to give dihydrojasmone. Examples are given of the preparation of (a) [2 - (21 - pentynyl) - 3 - keto - 1 - cyclopenten]-yl acetic acid methyl ester (b)[2-methyl-3-keto-1- cyclopenten]-yl acetic acid methyl ester (c) [2-pentyl-3-keto-1-cyclopenten]-yl acetic acid methyl ester which is hydrogenated to give methyl dihydrojasmonate (d) [2-hexyl-3- keto- 1-cyclopenten]-yl acetic acid methyl ester (e) [2 - allyl - 3 - keto - 1 - cyclohexen] - yl acetic acid methyl ester (f) [2-octyl-3-keto-1-cyclopenten]-yl acetic acid methyl ester (g) a mixture of [3 - keto - cyclopenten] - yl acetic acid methyl ester and [3-keto-1-cyclopenten]-yl malonic acid dimethyl ester and (h) 2-allyl-3- keto-cyclopenten-1-yl methyl acetate.

Title: Closed torus tire
IPC: B29D30/00
Filed: 1977-04-05
Abstract: A closed torus tire in which the cord or wire reinforcement ply, or plies, surround the inflation chamber which can retain pressure without being mounted on a wheel. The reinforcement ply is continuous circumferentially of the tire and axially in the crown and sidewalls. The circumferential ply edges are lap-spliced in the inner wheel-engaging part, rather than being folded around bead cores. The tire is made without use of a building core of any kind, thus avoiding the cost and difficulty of removing such core from the completed tire. The tire is made by wrapping the reinforcement ply, or plies, about a cylindrical drum to form a sleeve. An inner liner is then wrapped about the sleeve, a reversal of normal tire building practice. One circumfferential edge of the sleeve is then moved outward and axially over the remaining sleeve, beyond the other, unmoved edge. The one edge is then moved inward and axially under the other edge to form the lapped splice.
