Abstract: A fluid injection system for dispensing a solution into a fluid flow in a flow line, the fluid injection system including a storage tank having product to be dispensed therein; an inlet connection diverting fluid from the flow line into the tank; an outlet connection returning a mixture of fluid/product back into the flow line; a metering gauge in fluid communication with the inlet connection measuring water flowing into the tank; and a metering head connected to the storage tank and having multiple ports for connection to the inlet connection depending on whether the product to be dispensed is in liquid dry form. The inlet connection includes an inlet probe having an opening defined by an arc at a downstream side. The outlet connection includes an outlet probe having an opening having an angled cut facing downstream, such that a pressure differential is created between the inlet and outlet probes.

Abstract: A clothing folding system is provided comprising: one or more folding guides comprising: two or more sections of substantially rigid material: and a flexible web disposed between any two of the two or more sections of substantially rigid material, enabling the folding guide to be folded along the length of the flexible web: wherein the one or more folding guides are sized so as to enable each folding guide to be used to place the folding guide in contact with an article of clothing, folding the article of clothing in a folding pattern defined by folding each flexible web of the folding guide, wherein the folding guide remains folded within the article of clothing: and wherein the folding of multiple articles of clothing using the folding guides presents a plurality of articles of clothing that are substantially consistent in shape and size in their folded state, and such folded articles of clothing thereby are suitable to be stored in a sustainable organized arrangement.

Abstract: A cantilever feedback mechanism includes an upper cantilever and a lower cantilever. The upper cantilever and lower cantilever have a resistance spring rate to facilitate movement of the bellows over a selected range of resistances. The upper cantilever has downwardly oriented upper cantilever stops. The lower cantilever has upwardly oriented lower cantilever stops that engage the upper cantilever stops. Mean are provided for applying a preload to maintain the lower cantilever stops and the upper cantilever stops engaged until a force urging movement exceeds the preload.

Abstract: A lubricant coating for laser printer wiper blades is a solution applied to a laser printer wiper blade before install that reduces friction between the wiper blade and the photoconductor drum of a laser printer in order to reduce wear, prevent damage and increase life of the wiper blade and photoconductor drum. A leveling and wetting agent ensures uniform application and reduces coating defects. An anti-wear agent reduces friction and acts as an electrical insulator. A friction reducing agent also reduces friction and acts as an electrical insulator. An evaporation promoting agent aids in evaporation of unnecessary material after application to a wiper blade. A coating enhancing agent increases the hardness of the coating and provides assistance in adherence of the solution to the wiper blade. Deionized water acts as a carrier. The solution is mixed in a high shear mixture.

Abstract: A wellhead coupling and method for coupling and sealing an annulus formed between overlapping ends of an outer pipe and an inner pipe. A clamp housing grips the inner pipe, forms a horizontal landing base for the outer pipe, and forms circumferential ports aligned with the annulus.
