Abstract: A device for floated pumps with coaxial, opposite, modular pistons (7), operated by double eccentric cams (5), comprises pumping groups operating in parallel onto one and the same working chamber communicating with safety valves - one for suction and one for sending - and they may be aligned, kept together by tie-rods in higher or lower number, thus allowing differentiated flows and consequently differentiated powers.     Said pistons (7) have a large diameter and a short run, and their sealing is determined by elastomeric, flexible membranes (8) resting on bevellings which assure the functioning thereof, even under high pressures.     Also said valves (17, 20) of the pump are formed with elastomeric, flexible membranes onto thin slits, which are efficient also under high pressures.

Title: Dual equipment to identify telephone calls
Inventor: CAMARENA MARIANO CENTENO
IPC: H04M3/42
Filed: 1997-07-03
Granted: 2004-01-20
Abstract: The dual equipment for identification of telephone calls is a terminal electronic device that meets the telephone specifications for the service of Caller Identification.            It is an intelligent electronic equipment that is connected to the telephone line of a called user that, upon receiving a call phone, presents through a liquid crystal display the caller's telephone number information. The equipment can also store in the memory the telephone call identification when the subscriber is not in his place of business, and thus when the user returns he can check who called, or from which telephone number, as well as the date and time.            It consists of a battery eliminator entry for its power supply and a support battery, it identifies the information sent to it by the network through the input signalization that can be of DMF (Dual Tone Multifrequency) type or FSK (Frequency Shift Keying) type.

Abstract: A farrowing crate is disclosed. The farrowing crate includes an end support and an opposed end support. Back and front portions extend therebetween. Back and front portions includes top and bottom rails and a plurality of bowed bars extending therebetween. Back and front portions include an arcuate section and a straight longitudinal section. The distance between the bottom rail of the back portion and the bottom rail of the front portion is greater than the distance between the front and hind legs of the sow but less than the turning length of the sow. The distance between the front spaced apart bars and the back spaced apart bars varies between a maximum distance proximate to the arcuate section of each of the top and bottom rails of the front and back portion wherein the distance is greater than the turning length of the sow and a minimum distance wherein the distance proximate to the end portion and the opposed end portion is greater than the distance between the front and hind legs of the sow but less than the turning length of the sow. Preferably the spaced apart bars are generally vertical bars that are either bowed or angled. The curvature of the bowed bars or the apparent curvature of the angled bars vary along the length of the back and front portions. The curvature bars increases as they approach the arcuate section. The curvature bars decreases as they approach support members. The farrowing crate of the present invention provides enough space for the sow to turn around 3600, this allows the sow to visually monitor her piglets in all directions and allows her to change posture more easily. The farrowing crate provides adequate room for the sow to stand and lie down comfortably when she is aligned along the diagonal.

Abstract: A latch for a wire gate includes a frame defining a post confining enclosure.  The frame is clamped to a fixed fence post in a substantially horizontal orientation.  One of the sides of the frame is pivots about a substantially   vertical axis.   A spring biases the pivotally mounted side toward a closed position against the frame.  A guide channel is provided for directing a movable fence post between the pivotally mounted side and the frame.  The latch, as described above, enables a person to close a gate with one hand by pushing a movable fence post into the guide channel.  As the post passes along the guide channel, the biasing force of the spring is overcome sufficiently to move the pivotally mounted side to an open position and allow entry of the post  into the post confining enclosure.

Filed: 1998-06-11
Granted: 2004-05-11
Abstract: A method of manufacturing a conveyor belt having an elongate body made of uncured rubber and/or synthetic rubber. A polymeric parting material is placed adjacent to the upper and lower surfaces of the body, and heated platens are applied to the upper and lower surfaces of the body (i.e. belt material) to soften the adjacent upper and lower layer portions of the belt. This causes the softened belt material to flow into interstitial openings in the parting material. The resulting belt has the parting material squeezed into a thinner layer and embedded in the adjacent surface portions of the body of the belt. This provides a substantially uniform and reflectively soft texture surface.
