Patent number: 5039243Abstract: Crayons are provided with microcapsules containing fragrant materials within the shell of the microcapsules. Applying color to surfaces ruptures some of the microcapsules and releasing a fragrance. Some microcapsules remain intact within the color applied to the surface and may be ruptured by abrading the coloration on the surface. The colors and fragrances may be chosen to correspond with each other.Type: GrantFiled: July 7, 1987Date of Patent: August 13, 1991Assignee: Minnesota Mining and Manufacturing CompanyInventor: Dennis P.

Patent number: 5037088Abstract: 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.Type: GrantFiled: March 29, 1989Date of Patent: August 6, 1991Inventor: Lawrence A. Bernstein

Patent number: 5033738Abstract: 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.Type: GrantFiled: June 6, 1989Date of Patent: July 23, 1991Inventor: Milton A. Newton, Jr.

Patent number: 5029849Abstract: 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.Type: GrantFiled: April 12, 1989Date of Patent: July 9, 1991Inventor: Paul S. Nurkowski

Patent number: 5026286Abstract: 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.Type: GrantFiled: May 19, 1989Date of Patent: June 25, 1991Inventor: Gerriet Hellwig

Patent number: 5022172Abstract: 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.Type: GrantFiled: March 18, 1988Date of Patent: June 11, 1991Assignee: Sanyo Electric Co., Ltd.Inventors: Tsugio Kawahara, Hiromasa Harashima, Shunji Ubukata, Kazuo Kameda, Hirohito Moriya, Yoshihisa Inamura

Patent number: 5013034Abstract: An exercise machine has a rigid base on which stands a person wishing to exercise. One or more handles extend from the base and are each connected thereto by a friction pivot assembly. The person exercises by moving the handles against the friction of the pivot assemblies. Each pivot assembly has two or more physically fixed non-parallel axes about which the corresponding handle rotates, and this allows a wide range of movement of the handles. The pivot assemblies have bearings for providing frictional resistances to movement about each axis, and those resistances are independently adjustable.Type: GrantFiled: March 5, 1990Date of Patent: May 7, 1991Assignee: Health Habit Developments LimitedInventors: Adrian A.

Patent number: 5007753Abstract: Window cleaning apparatus is described which has a cleaning head that is rotatable to any position when used on a window surface. The apparatus includes a rotatable sleeve coupling which is positioned between the cleaning head and the handle for the apparatus. A cleaning element, such as a wiper, cleaning pad, sponge or brush, is attached to the cleaning head. Because of the rotatablity of the cleaning head, the apparatus effectively cleans edges and corners of windows of any shape. The described apparatus optionally includes a fluid supply conduit for delivering a cleansing fluid from a pressurized source to a fluid distribution conduit positioned on the cleaning head. The fluid distribution conduit contains perforations which enable fluid to be sprayed onto a window surface.Type: GrantFiled: December 30, 1988Date of Patent: April 16, 1991Inventor: Raymond B.
