The colors and fragrances may be chosen to correspond with each other.

Abstract: A compact multi-purpose exercise device includes two adjustable length arms which are pivoted together at one end and which has adjustable angle handles or actuators at their other ends. At the pivot point of the two arms a hydraulic resistance member is provided which has a substantially constant force, which may be adjusted, and which is substantially independent of the speed at which the handles are actuated relative to one another. The constant force is provided by a reverse Pelton bucket, which includes a spring-biased member in the hydraulic fluid flow path which is moved to reduce hydraulic flow resistance with increased velocity of the hydraulic fluid flow. Hydraulic fluid is directed to the reverse Pelton bucket assembly by a vane which is rotatable in a hydraulic fluid chamber as the arms are rotated relative to one-another.

Abstract: A central, length-delineated spine is formed by successive U shaped arms to which a pair of novel starting blocks can be attached, one on each side, and slid to such positions as desired by the runner. Each starting block is formed with a hollow open bottom side housing or box which will fit down over an anchorage block carried by successive U arms so as to lock the two together at a particular position along the spine. When raised free of such lockage, a starting block can be slid lengthwise due to (a) a pair of projecting lips or edge rails formed lengthwise along the starting block and along the hollow housing, and (b) composite slide rails formed by alignment of successive anchor blocks of a line of arms. Such starting blocks are easily raised and slid to new positions but cannot fall off the assembly (which might injure a foot) even if the assembly is inverted.

Abstract: An apparatus for weight training is attached to a weightlifting device, such as a barbell or a selectorized weightlifting device. A second weight to be lifted is then coupled to the apparatus. The apparatus is adjusted for the varying skeletal configurations of various individual users. Within one portion of the exercise stroke of the invention, the resistance to lifting continuously varies between that of the weight lifting device and the sum of the weightlifting device and second weight. Thus, the effect of the lifting stroke is increased for each exercise stroke.

The head is rotatably or rigidly secured to a substantially S-shaped adapter which, in turn, is rotatably or non-rotatably secured to the adjacent end of a shank that is implantable in the cavity of a femur. One or more distancing rings can be inserted between the adapter and the head.

Abstract: In order to overcome difficulties which arise when making conventional color charts and color spaces, a torus-shaped spacial structure is used as base body for the arrangement of color tones.The gray tones are located at the outermost jacket area thereof and the clearest colors are located at the inner jacket area thereof. In the inside of the body, the colors extend through all color tone steps from the clearest up to the gray tones. By means of an iterative method for the arranging of color tones in the torus, it is possible not only to discriminate the color tones for the human eye equidistantly, but also to represent the brown colors reliably.

Abstract: An automatic vending machine, or a slot machine, has a display plate provided at the rear wall of a sample room which is covered by a transparent window panel fitted in a front door of the machine. A plurality of vertically elongate display strips arranged side by side at desired intervals adjacent to the display plate to be rotatable about their own axes. The front or rear faces of these display strips can cooperate with each other to produce associated composite figures, which fully covers the display plate when the display strips rotate together at the same time whereby either the front or rear faces of the display strips take their positions substantially parallel to the display plate. Consequently, the composite display figures formed by the front and rear faces of the display strips can be seen from the front of the machine.
