Abstract: A progressive ophthalmic lens with a continuous progressive surface comprises a substantially constant power first area matched to far vision. It also has a substantially constant power second area matched to near vision. Between the first and second areas is a progressively varying power third area. This is defined by a central part extending to both sides of the main progression meridian. In this central area each line on the progressive surface parallel to the main progression meridian substantially satisfies at every point the following equation:1/R1-1/R2=constantwherein R1 and R2 are the principal radii of the surface at the point concerned.

Abstract: This relates to an apparatus for progressively heating wire and strip from one end to the opposite end thereof for the purpose of annealing the wire and strip or like function. The wire or strip is wound in a spiral groove formed in a drum which is formed of electrically conductive metal and is mounted in conjunction with a coil assembly to function as an armature of a D.C. generator. The power supplied to the coil assembly will be constant and the drum and the wire or strip wound thereon will function as a shorted armature of such D.C. generator so that all electrical energy induced into the drum and the wire will immediately be converted to heat energy. The drum is rotated at a selective speed with the rate of rotation of the drum controlling the amount of heat energy induced into the wire or strip.

Abstract: This relates to an induction heating coil which is of a single turn construction and particularly configurated for inducing electrical energy into a metal foil barrier layer of a laminated container closure for effecting heat bonding of the closure to a container in a preselected seal pattern. The seal pattern contains either one corner or the closure is provided with a projecting pull tab wherein there is a greater heating requirement and thus a requirement for the induction of higher electrical energy into the closure. The need for the induction of a greater amount of heat into the closure at a corner or the location of a projecting pull tab is provided for by reducing the cross section of the heating coil at the location of the greater heat requirement. The reduction in cross section is primarily effected by forming a notch in the heating coil. If desired, a closer control of the heating effect of the coil may be obtained by positioning in the notch a ferrite insert.

Abstract: A clutch release bearing comprises a maneuvering member operated on by a control member, usually a clutch release yoke. A drive member in direct or indirect axial bearing engagement with the maneuvering member, when operated on by the latter, operates on the clutch release device of a clutch. An axially acting spring washer of the Belleville spring type urges the drive member against the maneuvering member and retains the drive membering relative to the maneuvering member in the axial direction. This spring washer is able to turn inside out selectively so as to assume one or other of two separate stable configurations. One of these is a concave configuration and the other is a convex configuration. One configuration is an inoperative configuration and the other is an operative one. One peripheral edge of the spring washer bears axially on the drive member when it is in the operative configuration. On its other peripheral edge is a set of lugs through which it bears on the maneuvering member.

Numerous embodiments are envisioned although only a limited number of alternatives is specifically disclosed.

Abstract: This relates to a mechanism for transferring carton lids from a hopper or magazine to a carton closing machine and more particularly to a sealing head of such a machine. The carton closing machine has a plurality of sealing heads each carried at a work station and mounted for rotation with the machine. The carton lid transfer mechanism includes a picker for pulling a lower most lid from the hopper and thus assisting in the transfer from the hopper to a ferris wheel assembly in sequence carton lids. The ferris wheel assembly then deposits each picked up lid on to a lid carrier of a merry-go-round assembly. The merry-go-round assembly then transfers each lid to the respective sealing head of the carton closing machine.

Abstract: The device allows the physical quantity used for the feedback-governing of the supercharging pressure of an internal combustion engine to be corrected as a function of ambient air temperature.

Abstract: To avoid skidding of the driving wheels of a tractor (1) which runs on tires and which is fitted with hydraulic lifting devices (3, 4) on which are mounted working tools (35, 45) which are buried in the ground (in this case ploughs), the apparatus includes detector structure for determining the force for forward movement of the tractor, comparing that force to a reference value and producing pulses of less than one second, for alternately raising the two lifting devices (3, 4), the amplitude of the pulses being proportional to the excess of the forward movement force, up to a limit amplitude of centimeters approximately. The pulses are too short for the tools (35, 45) to lift with respect to the ground and the amplitude of the raising movement appears as squashing of the tires, which increases grip in order to overcome the excess of forward movement force.

Abstract: A switch mechanism comprises, movably mounted between a fixed yoke and at least one fixed contact, at least one conductive contact arm which is articulated to the fixed yoke, which is itself conductive. The arm is controlled by an operating member available to the user to assume one or other of at least two positions in one of which it bears against the fixed contact through a bearing area and in the other of which it is spaced from the latter. A double pivot is used for articulating the conductive contact arm to the fixed yoke, which comprises two separate pivoting areas parallel to each other, one for each of said two positions of the conductive contact arm. The conductive contact arm itself comprises two distinct contact areas for cooperating each with a respective one of the pivoting areas.

Abstract: A basket carrier of the type including a base having a plurality of handles projecting upwardly therefrom, the handles also functioning as partitions so as to divide the base into a plurality of individual spaces for receiving cups, bottles and the like. The same basic basket carrier can be formed from two different blanks. It has been found that by providing two different blanks, a full nesting of the blanks may be obtained so that the blanks may be formed from a web with substantially no loss, thereby reducing the amount of paperboard required to form the blanks. The resultant carriers differ primarily in that one carrier includes one double handle and two single handle arrangements and the other carrier has two double handle arrangements. The carriers differ also in the manner in which the various portions are connected together by way of different arrangements of glue flaps.

Abstract: An internal combustion engine having a sleeve valve wherein the sleeve valve is the cylinder sleeve of a respective cylinder whereby a very simple reciprocation and oscillation of the sleeve valve may be effected by means of a rotary valve which controls the intake of a fuel-air mixture into the crankcase of the engine. By suppying the fuel-air mixture into the crankcase of the engine and providing each cylinder with transfer passages extending axially through the cylinder and radially adjacent cooling fins of such cylinders, it is possible to effect an isothermal compressing of a fuel-air mixture within the cylinder followed by that fuel mixture being adiabatically compressed by the movement of the respective piston towards the head. The use of a sleeve valve, particularly in association with rotary intake valves, provides for a very simple valving arrangement with a minimum of parts.
