Patent number: 4663538Abstract: A control system is provided for controlling the operation of at least a pair of coin actuated appliances. A control panel area is provided which includes a coin drop mechanism, selection switches and indicators. A microcontroller is in circuit association with the coin drop mechanism, the selection switches and the indicators. The microcontroller is operable for accumulating the value of coins received and for effecting a display of the value in the indicators. Upon operation of a selection switch for a particular appliance by the appliance user, the microcontroller will effect operation of that appliance and the assignment of the displayed value to that appliance.Type: GrantFiled: January 15, 1986Date of Patent: May 5, 1987Assignee: The Maytag CompanyInventors: Curran D. Cotton, David I. Ellingson, Donald E. Erickson, William J. Noe, James D. Wilson

Patent number: 4624023Abstract: A process for washing textile material wherein a non-foamed washing liquor, combined with a foam-producing chemical, is applied to a continuously fed textile material, the foam is produced on the textile material by effecting alternating compression and pressure relief of the textile surface while simultaneously loosening the dirt, and finally the foam, and thus the dirt dissolved in and taken up by the foam, is removed by suction.Type: GrantFiled: October 1, 1984Date of Patent: November 25, 1986Assignee: Fleissner GmbH & CompanyInventor: Gerold Fleissner

Patent number: 4608767Abstract: Three consecutive work zones are provided in a drying apparatus for tubular textile wares, equipped with an expander arranged vertically floating in the interior of the tubular textile material. Zones, in which drying air is blown from the outside into the tube interior, are located upstream an entry ring which expands the tube and downstream of a corresponding exit ring of the expander, which may be circular, for example. In a third, center zone located between the entry ring and the exit ring of the expander, the tubular textile material is exposed to substantially radially outwardly directed suction of the drying air which may cause undesirable deformation of the tubular textile material. A gas-permeable substantially cylindrical jacket is provided in the center zone. This jacket envelopes the tubular textile material which bears against the inner wall of the jacket during the drying, whereby such deformations are avoided or controlled.Type: GrantFiled: May 7, 1984Date of Patent: September 2, 1986Assignee: Lindauer Dornier Gesellschaft mbHInventor: Peter Dornier

Patent number: 4592107Abstract: The crease displacement and the achievable dilution factor in the conventional continuous pretreatment or aftertreatment operations of fabric ropes with liquid means in rope washers are not adequate, and consequently the water consumption necessary for satisfactory results is too high. To date the existing problems can only be solved with squeeze rollers which, however, have an adverse effect on the goods.According to the invention the textile rope is now introduced into a treatment store of a liquid-operated jet apparatus, is subjected to the action of the treatment liquor, is then carried along by a steam- or more generally gas-operated jet arrangement and conveyed into an interim store, where dewatering takes place. From the interim store the goods, with satisfactory dilution factor, are then passed to the next isothermal or non-isothermal treatment stage of the same or a very similar structure.Type: GrantFiled: June 27, 1984Date of Patent: June 3, 1986Assignee: Hoechst AktiengesellschaftInventor: Hans-Ulrich von der Eltz

Patent number: 4551996Abstract: A washing machine with a drier having a washing machine body, a drier carrier mounted on the washing machine body and a drier body carried by said carrier. Almost whole part of the front surface of the drier carrier is concaved rearwardly to provide a concaved curved front surface. The upper end of the front surface of the drier carrier, which is flush with the fron surface of the drier body, is retracted rearwardly from the lower end of the front surface of the drier carrier which is flush with the front surface of the washing machine body. The rear end of the drier body is projected rearwardly from the rear surface of the drier carrier.Type: GrantFiled: October 15, 1984Date of Patent: November 12, 1985Assignee: Hitachi, Ltd.Inventors: Etsuro Hirose, Kimio Takahashi, Toshiro Mori, Haruyuki Kaito

Patent number: 4545135Abstract: Installation for the centrifugal spin-drying or combined spin-drying and drying of fibrous or porous materials comprising, in combination, a spin-drier and a material carrier adapted to receive at least one pile of spools or similar of fibrous or porous materials, said material carrier being formed from a plurality of supports each adapted to receive a pile of spools or similar, disposed along at least one ring about a common axis formed by a central caisson, said spin-drier being equipped with a basket comprising a plurality of pockets or similar each adapted to receive a pile of spools or similar carried by a support of the material carrier, said supports being designed to be each housed in a pocket of the basket of said spin-drier and the common axis about which said supports are disposed in a ring being formed by a hollow central caisson adapted to fit into the central pivot of the centrifugal spin-drier.Type: GrantFiled: April 27, 1983Date of Patent: October 8, 1985Assignees: Barriquand, RobatelInventors: B. Barriquand, F. Villard, M. Martin, M. Tridon, M. Pignal

Patent number: 4534188Abstract: A top loading clothes washer adapted for installation under a fixed or stationary upper structure such as a stacked dryer or countertop wherein the washer is pivotable to a forward tilt-out position providing access to the top and wherein a washer lid in sliding engagement with the top is automatically opened as a result of the tilt-out movement of the washer. Apparatus connected to the lid restrains its forward movement so that it is prevented from moving out from under the dryer or countertop as the top of the washer tilts forward.Type: GrantFiled: May 31, 1984Date of Patent: August 13, 1985Assignee: Speed Queen CompanyInventor: Robert M. Fey

Patent number: 4531387Abstract: A combination appliance is provided having a washing machine and a dryer separately supported above the washing machine. The physical arrangement of the washing machine/dryer combination provides a compartment below the dryer cabinet and behind the washing machine cabinet. A recessed area in the top cover of the washing machine and below the bottom of the dryer defines a pocket which is in communication with the compartment. A sliding access door is operable within the recessed area and is manually movable to a posture partially within the compartment and partially within the pocket for providing clear access to within the washing machine.Type: GrantFiled: December 27, 1983Date of Patent: July 30, 1985Assignee: The Maytag CompanyInventors: Curran D. Cotton, David I. Ellingson, William J. Noe, James D. Wilson

Patent number: 4526020Abstract: A top loading clothes washer pivotally supported so that it can be installed underneath a stationary structure and tilted forward for loading and unloading clothes. The pivotal support is provided by a stable base which also includes apparatus such as a hook for preventing forward tilting past a predetermined loading and unloading tilt-out position. The front of the washer is truncated and the tilt axis is backward from the truncation but forward from the washer center of gravity. In the upright washing position, rear feet on the washer provide support for the washer and also engage the base to horizontally secure the washer to the base for stability during spin dynamics. A biased hinge covering the front truncation provides backward torque about the tilt axis so that the washer feet carry a significant amount of the washer weight.Type: GrantFiled: May 31, 1984Date of Patent: July 2, 1985Assignee: Speed Queen CompanyInventors: Robert M. Fey, Ronald L. Altnau
