Title: Water saving dispensing device
Inventor: AUMAN C DAVID
IPC: E03D1/00
Filed: 1992-11-12
Granted: 1996-06-11
Abstract: A simple yet inexpensive device is presented which is used to divide the water normally supplied to the spill tube (18) and gooseneck reservoir (17) of a commode.  Dividing the water supplied to the spill tube and diverting a substantial portion of that water to a holding tank of a commode saves water that is normally unnecessarily fed directly down the drain in the refilling pro-cess.  The device is a small plastic insert that has a generally rectangular main body (1).  At one end of this main body is a horizon-tal inlet tube (2).  At the bottom of the main body are a number of lower vertical outlet tubes (4-7). In order to evenly disperse the inlet water among the vertical outlet tubes, the upper mouth of the vertical outlet tubes is constricted (15) by narrowing the diame-ter of the mouth with respect to the inner diameter of the outlet tube.  Water is thus distributed evenly among the lower outlet tubes.  By changing the number of lower outlet tubes that feed water to the spill tube or holding tank, the correct proportion of wa-ter supplied to the gooseneck may be obtained.

Title: Crosslinked cellulose products and method for their preparation
Inventor: GRAEF PETER A
IPC: D21H11/20
Filed: 1993-06-25
Granted: 2004-04-27
Abstract: The invention is a method of making a wet formed, sheeted, readily reslurriable sheeted crosslinked cellulose and the products made by the method. Crosslinked wood pulp fibers tend to be quite brittle. If crosslinked while in sheeted form, the sheets cannot be readily defibred, either in a wet or dry state, without serious fiber degradation. The sheet products of the present invention can be easily redispersed or repulped in water without significant fiber breakage. The present products are made by including within the sheet, while still in wet form, a debonding or softening agent which is preferably added before the latent crosslinking reactant. Most preferably the debonder is added prior to the headbox of a paper machine and the crosslinking reactant is applied near theend of the forming wire or at the press section. The treated sheet is dried conventionally. Crosslinking may occur entirely during drying or during a period of additional heating, usually at a temperature in excess of 100 °C for a short period of time.  Conventional debonding agents and crosslinking reactants are suitable. The softening agent apparently reduces or prevents adhesive bonding between adjacent fibers caused by polymer formation external to the fibers under reaction conditions.

Title: Process for injection molding objects consisting of at least two different layers
Inventor: ECKARDT HELMUT
IPC: B29C37/00
Filed: 1995-04-19
Granted: 1998-11-10
Abstract: The present invention relates to a process for the injection molding of objects consisting of at least two different layers. The outer layer here consists of enamel. According to the process, a liquid enamel is used. This enamel is injected by an enamel-injection apparatus (1) through an enamel-injection die (2). The plastic melt passes through an injection unit into the cavity (3). According to the invention, the liquid enamel is injected into the flow path of the melt in the region before the cavity, before the melt is injected, so that the melt is encased by enamel before it is distributed in the cavity (3). It is thus possible to use liquid enamels to enamel injection molded parts in the tool. Furthermore, the inventive process makes possible a rapid and therefore economical mode of operation.

Abstract: A rotary lobe pump comprises a pump housing defining an obround pump chamber and a pair of lobe rotors in the pump chamber. The rotors are mounted on rotatable shafts which are connected by timing gears such that the rotors rotate at a same speed but in a reverse direction and with the lobes thereof interlocking in such a way that the rotors cause a fluid to displace through the chamber. The pump chamber is defined in the pump housing by opposed front and rear end walls which are perpendicular to the axes of the rotors and by arcuate side walls with which the rotors make sealing contact and which gradually wear out thereby reducing the tightness of the seal and thus the pumping efficiency of the rotary lobe pump. The rear end wall includes two removable end wear plates which each include a rearwardly projecting key engaged in a corresponding keyway defined in the pump housing with bolts extending from outside of the housing inwardly towards the end wear plates and engaging the keys thereof for securing the end wear plates to the housing. The arcuate side walls take the form of removable curved wear plates which are each semi-cylindrical in shape and which each include an outwardly directed radial curved key which is engaged in a corresponding curved keyway defined in the housing. Bolts which extend through the housing into the keys retain the curved wear plates in position in the pump chamber. The rear ends of the curved wear plates are supported by the peripheral edges of the end wear plates.

Title: Perforate diaphragm alignment system for spring brake actuators
Inventor: PLANTAN RONALD S
IPC: F16D65/14
Filed: 1995-09-12
Granted: 2006-11-21
Abstract: A diaphragm for spring brake actuators includes an aperture that receives a threaded securement member such that the diaphragm is directly fixed to a push rod. In this way, misalignment between the push rod and the diaphragm is eliminated. To overcome any leakage through the aperture the diaphragm is formed with sealing beads compressed by the securement member to achieve a seal. Preferably, diaphragm plates are received on each side of the diaphragm, and the sealing beads are compressed by the securement member to achieve a seal between the securement member and the diaphragm plates. An adequate seal is thus achieved, while still allowing the direct connection of the diaphragm to the push rod by a threaded connecting member. The diaphragm plate on the power spring side of the diaphragm extends upwardly into a recess in the power spring plate, and is in facial contact in an axial direction with a surface of the power spring plate when the spring is actuated. At the same time, there is a clearance when the spring is compressed, such that misalignment of the push rod due to manufacturing tolerances is also eliminated. This contact resists misalignment between the power spring plate and the diaphragm plate, and consequently the diaphragm. There is some small radial clearance between the outer periphery of the diaphragm plate and the power spring plate such that the two members are "free floating" and may have some small amount of relative adjustment.
