Abstract: An ice making machine has one or more combined evaporator and shaped-ice making assemblies (54), each arranged in a generally vertical orientation and ice make-up water is communicated to a manifold arrangement (52) disposed above each of the assemblies and from which it cascades over the opposed surfaces of the assembly to freeze within the pockets or recesses thereof. The combination evaporator and shaped-ice making assemblies are so designed that the heat transfer between the evaporator coils and the water freezing within the ice pockets is such that substantially symmetrically-shaped (eg "pillow" shaped) ice products are formed within the pockets. Preferably an evaporator conduit (100) is arranged in a generally serpentine configuration and is provided with a plurality of heat transfer elements (110) which are disposed interjacent spaced parallel sections of the conduit, with the entire assembly of the evaporator conduit and heat transfer elements having a plastics material molded thereon. <IMAGE>

Abstract: Adjustment device for setting the relative length of two parallel rods (1, 2), which together make up a control rod.  The adjustment device is primarily designed for cheap and simple manufacture, and for easy installation without tools except for a grip.  According to the invention, the rods have end sections which work together and which have cross way grooves (7) and corresponding projections (6) which mesh with each other.  These end sections are held pressed together by means of a locking mechanism (3) with two spring loaded, rotating legs (4,5) which have longitudinal openings through which the rods' end sections go and whose short sides press these against each other by the slanting position of the legs relative to the rods' length.  To release the rods, they have meeting surfaces (11) which forma lengthways track shaped space (12), in which are tongues (13) from the legs.  These tongues are of such a width that the rods are separated when the legs are moved away from the locking position.<IMAGE>

Abstract: A method and equipment for thickening various suspensions, such as, e.g., pulp slurry, waste waters, or mineral sediments. The sludge or slurry is passed into a basin in which a filter unit rotates as partly submerged in the sludge or slurry. The thickened sludge or pulp web is gathered onto the surface of the filter unit from the sludge or the slurry in the basin. The sludge or slurry is passed from the basin to above the sludge or slurry level. In order to pre-thicken the sludge or slurry, part of the liquid contained therein is removed through a wall located between the feeding-in point of the sludge or slurry and the surface level of the sludge or slurry.

Abstract: In a portable cable winch the smooth shell of a motor-driven cable drum is provided with at least one conical surface having an angle of inclination corresponding to the angle of friction between the load-bearing cable and the cable drum. A clamping disk driven in synchronism with the cable drum pulls the load-bearing cable away from the smaller-diameter end of the conical surface and towards a cable storing means. The cable has applied thereto a clamping force which is transmitted as a pulling force back to the cable section to be drawn in via the conical surface. In an embodiment in which the shell of the cable drum is subdivided into two conical surfaces having identical angles of inclination but being disposed on the axis of the cable drum extending in opposite directions, it is possible also to employ the cable winch for raising and lowering loads upon the direction of rotation of the cable drum being reversed to alternatingly guide the cable onto the one or the other of the two conical surfaces. In both cases the cable drum is operated as a pull-through drum so as to prevent the individual turns of the cable from being superimposed, with the result that it is possible to drive the drum independently of the length of the cable by applying a constant invariable torque thereto.

The linear movement of the individual servo-cylinders (46) is converted into a substantially proportional rotary movement over the whole working range of the servo-cylinder (46). Said power transmission mechanisms are so designed that when one or more of them is in action and the portions of the manipulator arm (7, 8, 10) are moved in relation to one another, the other power transmission mechanisms are not influenced as a result of these movements. All the servo-cylinders (46) have a piston rod (47), the diameter of which is reduced to below the bending limit for a conventional freely mounted piston rod, since the piston rod (47) is rigidly connected, at one end, to the piston (48) of the servo-cylinder (46) and is rigidly connected, at the other end, to a guide (50) adapted to slide or roll (51) in fixed guides (52), as a result of which the contact area and hence the friction between the piston rod (47) and piston rod packing (59) is reduced to a minimum.

Abstract: A continuously variable multi-focal soft contact lens wherein a continuous optical gradient in a region smaller than the maximum pupil opening is provided. The concave surface is aspheric with a desired optical power for distant viewing at the center which increases to the desired near vision power. The increase is usually about 3 to 5 diopters within 6 mm of the anterior optical zone (AOZ) which is approximately 9.7 mm in diameter when wet. Outside this 6 mm zone the concave surface is essentially spherical. The concave surface is an aspheric curve having a steeper curve in the middle than a base curve r2. The curve at the center is the steepest and is designated as r2'. Once r2 and r2' curves are determined, the thickness of the lens (t) and the radius of curavation for AOZ designated r1 is calculated using the desired optical power at the apex of the lens (Pw) and desired thickness at the junction (JTK) of the AOZ, based on the following equation:   <IMAGE>   wherein Exp is the expansion factor and n is the index of refraction of the lens when wet, all other dimension in the dry state, before expansion.

A predetermined amount of a flowable product is introduced into each of the open top packets. Next, the upper corner portions of each individual packet are sealed and a prdetermined portion is cut from each upper corner. The upper corner portions of each packet then are pulled away from one another in a generally horizontal direction to urge the spaced apart upper marginal edges of the sidewalls of the packet toward one another. After the upper corner portions have been pulled away from one another, the upper marginal edges of the packets are sealed together to close the packet.
