Patent number: 6758372Abstract: With soap and cleansing foam dispensers, there is a risk that they may be equipped with supply containers of unsuitable liquid or that their intermediate containers may become contaminated. According to the invention, an adapter (8) that is mounted on an intermediate container (6) has a coded cylindrical jacket (10), into which coded parts (4,5) that are positioned on the neck of a suitable supply container (2) can be fitted. To prevent the contamination of the intermediate container (6), the latter has a spring-loaded internal sealing plug (50) which ensures the hygienic sealing of the container even prior to use and when the supply container is changed. To prevent interruptions in the operation, a reliable fill-level indicator (22) is provided. The device thus ensures improved, hygienic dispensing of soap-solution in dispensers (1).Type: GrantFiled: June 28, 2002Date of Patent: July 6, 2004Assignee: HTS International Trading AGInventors: Hans-Jörg Studer, Markus Ehrensperger

Patent number: 6626332Abstract: The invention relates to a dispenser for foamable liquids which has been improved with regard to the aspects of hygiene and reliability. According to the method, in addition to the pneumatic and hydraulic parts of the dispenser having a configuration which is to a great extent isolated from the external atmosphere, said dispenser has an air chamber (82) which subjects a nozzle/expansion body (74) first to an excess pressure and then to a negative pressure during the return stroke (HB) of an air piston (42) via a lateral bore (89). As a result, the outlet (80) is first cleared and any remaining foam in the nozzle/expansion body (74) is subsequently removed by suction and coagulated into soap solution. During the next working stroke, this minimal quantity of soap-solution is foamed again and expelled.Type: GrantFiled: July 18, 2002Date of Patent: September 30, 2003Assignee: HTS International Trading AGInventors: Markus Ehrensperger, Hans-Jörg Studer

Patent number: 6588026Abstract: A method for introducing liquid agents, such as cleansers or disinfectant, into the water supply of a sanitary facility, such as a water closet includes the monitoring of the pressure characteristics of a flush cycle and determining an appropriate time during the cycle for introduction of the liquid agent. A subsequent flush cycle is similarly monitored. At the determined time the agent is added. Preferably, the determined time is towards the end of the flush cycle. An apparatus for carrying out the method includes a liquid reception, a pressure sensor located in a line connecting the reservoir to the water supply line for the sanitary facility, and a control unit which operates either a pump or a valve. The liquid can be introduced into the water supply either by the pump or by suction.Type: GrantFiled: November 21, 2001Date of Patent: July 8, 2003Assignee: HTS International Trading AGInventors: Hans-Peter Meier, Hans-Jörg Studer

Patent number: 6568561Abstract: A device for the linear drive of a pumping member in a soap-type dispenser includes a crank mechanism with a crank disc and a push rod transmitting a linear movement to a piston rod. Disengageable coupling members are located between the push rod and the piston rod to disengage the piston rod when an actuating signal is not present. The coupling members can be re-engaged upon further movement of the crank disc. The device may be employed in conjunction with a motor driven pumping member and a sensor with a control circuit to detect the presence of a hand to be supplied with the soap and generate the actuating signal.Type: GrantFiled: July 18, 2002Date of Patent: May 27, 2003Inventors: Hans-Jörg Studer, Markus Ehrensperger

Patent number: 6267460Abstract: A towel dispenser is provided with a pivoting unit into which a winding roller driven by way of a friction drive is mounted in an easily suspensible manner. An additional loop, which is tightened by a compensator roller in a direction +p, is formed in the dispenser in front of the winding roller, and when clean towel is pulled down a portion of used towel (T′) is used to form the rear part of a loop of cloth (T; T′) used in the front part. Changing used cloth (T′) and loading with clean towel (T) is performed by rotating the pivoting unit, can be carried out in a very simple manner and is completed by opening or closing the cover of the dispenser. A path- and time-dependent control of the towel delivery is integrated in the dispenser.Type: GrantFiled: January 20, 2000Date of Patent: July 31, 2001Assignee: CWS International AGInventors: Albert Gaide, Patrick Besserer, Markus Ehrensperger, Christian Frei, Hans-Jörg Studer

Patent number: 6254065Abstract: An evaporation dispenser for freshening the air in closed spaces such as toilets, washrooms and waiting rooms, telephone booths and lifts. A mounting plate is arranged in a housing and is divided into two chambers by a horizontal separating surface. The lower chamber serves as an evaporation space and holds two bottles of active substance which form a saturated atmosphere in the chamber via evaporating elements. This atmosphere is diffused into the outside air by means of a fan which draws the saturated atmosphere from the evaporation space. Simultaneously, ambient air is drawn into the evaporation space to become saturated. Both the discharge of the saturated atmosphere and the drawing in of ambient air may be performed by a single rotor compressor, the rotor being divided into two sections by a radial divider. The discharge of the saturated atmosphere may be controlled by a microcontroller coupled to sensors which monitor activity in the closed space.Type: GrantFiled: January 11, 2000Date of Patent: July 3, 2001Assignee: CWS International AGInventors: Markus Ehrensperger, Hans-Jörg Studer

Patent number: 6211637Abstract: Soiled and/or contaminated objects often have to be collected before they are specifically disposed of. According to the invention, in order to prevent blockages in toilets and sewers, a contactlessly operating container (1) is used which has a lid (2) which opens when a hand or an object approaches a proximity detector (50). The container (1) is suspendable from a supporting housing (12) accommodating the entire control means, the drive and the power supply. A preferred use of the device is the disposal of sanitary towels (14) which are immersed in a gel (15). The container (1) is periodically replaced by a clean container so that satisfactory hygiene conditions can also be maintained in frequently used toilet areas.Type: GrantFiled: March 24, 1999Date of Patent: April 3, 2001Inventor: Hans-Jörg Studer
