    Abstract: A modular floor mat unit which can be used individually or in combination with adjoining floor mat modules to provide an elevated surface which insulates personnel or materials from the floor surface. The floor mat is a unitary structure comprised of a tread surface integrally attached to the top edges of interconnected flanges which form a support frame. A plurality of drainage openings in the tread surface allow liquids and other substances to be removed from the tread surface to the underlying floor and also ventilate the area beneath the mat. Unitary traction plugs fabricated from a flexible resilient material protrude above and below the floor mat to provide traction and prevent slippage. A plurality of finger elements having inclined top surfaces and detent interlock devices protrude from all sides of the floor mat to provide both an inclined threshold surrounding the mat and means for interlocking adjacent mat modules to form a larger mat area.

    Abstract: A detergent dispensing system for sequentially and automatically injecting various liquid products (e.g., detergents, fabric conditioners, neutralizers, etc.) into a laundry washing machine. Each liquid product is independently connected to a venturiaspirator positioned within separate carrier fluid conduits (e.g. water conduits) and product is drawn into the respective carrier fluid conduits upon passage of carrier fluid therethrough. Electrical control means, including electrical timing apparatus, triggered by a signalling device synchronized with the machine washing cycle selectively actuates and deactuates a solenoidoperated valve positioned upstream of each venturi-aspirator so as to allow injection into the carrier fluid of a predetermined quantity of each liquid product at the desired point in the machine cycle.

    Abstract: A system for selectively adding a plurality of liquid chemicals to a laundry machine in response to triggering signals from the machine is disclosed. Pumps are provided for pumping chemicals from their shipping drums through conduit means to the washing machine. Control means are associated with this system allowing the operator to remotely vary the chemical mix pumped to the washer by making control switch selections. The selections correspond to the soil levels of the laundry load, the presence of greasy soils, the need for bleach and the presence of permanent press fabrics. This injection process is controlled by a plurality of sequentially activated electrical timers that energize relays to in turn energize the pumps in selected groups. Means are provided for limited remote monitoring of the function of the system.
