Abstract: A single-piece piston and drive assembly for use in a motor-actuated pump to meter a predetermined amount of lubricant or other liquid. The drive assembly includes a rotatable drive shaft, an eccentric cam insert, a cam rod, and a rocking beam. The rocking beam is coupled to the piston, the cam rod shaft, and a biasing mechanism. When the drive shaft is rotated, movement of the cam rod shaft causes the rocking beam to pivot and move the piston along a stroke to dispense the liquid. The piston operates in association with a flow adjustment stem that regulates the amount of liquid metered by the pump, and a valve assembly for evacuating the liquid from the pump chamber into and through an outlet fitting.Also provided is a flow volume indicator for use in a pump for indicating the amount of liquid being discharged. The flow volume indicator has a main body with an annular side wall, flexible base wall, and a knobbed pointer that is inserted into a bore of the pump body and coupled to the flow adjustment stem.

Abstract: A water pump allows adjustment of the drive belt by rotating a portion of the water pump housing. The water pump eliminates the need for additional drive-belt tensioning parts, therefore simplifying maintenance procedures. The pump housing has a support member mounted thereto, with a pump shaft extending therethrough. The support member flange includes eccentrically-formed mounting grooves. The support member is rotated by the loosening of adjustment screws securing it in place. By rotating the support member, the location of the pump shaft is re-oriented and the tension of the drive belt adjusted.

Abstract: A system is provided that accurately measures the quantity of liquid that is transferred through a flow meter. The system is composed of a flow meter with an ultrasonic fluid (liquid) sensor mounted therein that operates to sense the presence or absence of liquid flowing through the flow meter so that air flow is not erronecously measured as liquid flow. When there is substantially no liquid flow through the meter, the ultrasonic fluid (liquid) sensor interrupts the transmission of an output signal from a signal-conditioning circuit to a totalizer that operates to process the signal and total the amount of liquid so that any non-liquid material passing through the meter is not included in the total amount of removed liquid by the totalizer. Also provided are methods of using the system to accurately measure the amount of liquid flowing through a flow meter, such as in a grease trap pumping operation.

Abstract: A disengageable pivot connection includes a ball stud that is capable of being selectively removed from the corresponding socket. The ball stud includes an engagement head that has substantially flat faces or grooves that correspond to tabs extending from the rim of the socket into which the ball stud is engaged. To install, the ball stud is inserted into the socket such that the substantially flat faces or grooves on the head pass by the tabs extending from the rim of the socket. Then, the ball stud is rotated such that the head engages the tabs extending from the rim of the socket. Alternatively, the head of the ball stud is snap-fitted into the socket as is conventional in the art. As such, the head cannot be removed from the socket without additional rotation. The head remains free to pivot within the socket as required for the particular application. One particularly desirable application of the present invention is in automotive lamp assemblies.

Abstract: A coupon burster assembly receives a continuous supply of coupons in the form of a web where the forwardmost coupon is attached to the following coupon along a weakened web portion. The burster includes a pair of intermittently rotating feed rollers and a pair of continuously rotating delivery rollers. An activation input receives triggering information from a form-fill-seal packaging machine or from a receiving product sensor. When the activation input receives triggering information, a signal is sent to a clutch-brake to activate the feed rollers. The feed rollers then feed the web into the delivery rollers. When a deactivation sensor located beyond the delivery rollers senses the presence of the forwardmost coupon, a signal is sent to the clutch-brake which stops the rotation of the feed rollers. Because the delivery rollers continue to pull the forwardmost coupon, the two coupons separate along the weakened web portion. The forwardmost coupon can then be delivered to the dispensing location.

Abstract: This invention relates to formulations comprising film-forming components capable of forming per se a physical barrier to pathogens. Thermoreversible gels such as poloxamers are particularly preferred for that use. The film-forming formulations may further comprise microbicides, spermicides or any other drug, which choice is guided by the pathogen, organism or the disease to be inactivated or treated. The formulations are therefore efficient as a physical, and optionally, as a chemical or pharmacological barrier as well as usable as a sustained drug-release system at the locus of administration. A part of the drug may also be entrapped in liposomes or other drug carriers. These formulations are intended for use in the prevention of sexually transmitted diseases, as well as in the treatment of infections, cancer, inflammation or any disease or state which requires a pharmacological treatment. Formulations are applicable to mucosae, skin and eye, for example.

Abstract: A bobbin for use in a three-phase line reactor. The bobbin includes a tubular main body with a first end, a second end, a first side, a second side, and a core that extends from the first end to the second end. The main body also has two radially-extending flanges; one on its first end and another on its second end. Four tabs extend axially from the main body and are integral with it. A first tab is positioned on the first end of the main body extending from the first side and a second tab is positioned opposite the first tab on the second side. A third tab is positioned on the second end of the main body extending from the first side and a fourth tab is positioned opposite the third tab on the second side. The integral tabs eliminate the need for metal support bars used to hold and align laminations inserted into the cores of the bobbins. Thus, fixing laminations in place is more accurate and repeatable than with prior bobbins.
