Patent ES-8600876-A1 (ES)
Title: Injecting machine for meat pieces
IPC: A23B4/28
Filed: 1984-05-07
Abstract: An improved fluid injection (brine, phosphates, etc.) system for meat pieces which obviates the formation of foam by preventing air from entering the injection needles by two means: First, each multi-orificed needle is constrained to pass through an aligned duct or channel in a meat pressing block wherein is formed a discrete fluid chamber at the upper section of the duct and a close-tolerance needle guide in the bottom section. The fluid chamber is always filled with the substance to be injected, but when any of the needle's orifices are exposed to this chamber under pressure (i.e., not fully penetrated into the meat piece) the fluid chamber overflows the pressing block which triggers the shutdown of the fluid pump or pressurizer. Secondly, an "inverted-V" pipe is fixed to the movable injection head assembly so as to feed fluid to all needles through a common manifold either under pressure or through gravity-assisted drainage (between injection phases), thus always ensuring a positive flow of pure liquid through each needle. Additionally, a dual-plate sliding mechanism is provided to facilitate locking in or removing needles from the head assembly. A meat-gripping conveyor also cooperates with the injection head.

Abstract: The operation of a target computer (102) is monitored by a terminal controller (101) connected to one or more of the computer's input/output ports. The controller can send data on one of the computer's ports and simultaneously record and monitor computer responses at several of the computer's input/output ports.

Received information, in addition to being searched for a specified character string, is also examined for message type and a message type designation is added to each data word or message transferred to the demux queue. From the demux queue the data is transferred to different storage files (215, 217) depending upon the message type designation. The transfer of data through the queus is controlled by several processes (211, 213) which communicate via a shared memory area. Such a set of queues and processes is provided for each monitored port, operating independently from processes for other ports.
Patent ES-8704623-A1 (ES)
Title: Tube cleaner for heat exchanger
IPC: F28G1/12
Filed: 1986-07-01
Abstract: Recirculating tube cleaners pass through the internal diameter of the tubes of a bundle of heat-exchanger tubes. Use is made of tube cleaners of variable density which are subjected to a pressure in order to compress them and which have a neutral ascending force when they enter the internal diameter of the tubes from an inlet manifold (collector). On their exit from the outlet manifold of the heat exchanger, the tube cleaners recover their positive or negative ascending force in accordance with the embodiment. A collecting device intercepts the tube cleaners which have a positive ascending force on the upper part of the circulation (route) and direct them towards a recirculation system. The tube cleaners made from open-cell elastomer which have a negative ascending force may be intercepted in the lower part of the circulation and are then partially dehydrated so that they have a tendency to exhibit a neutral ascending force. Unlike what occurs in prior-art embodiments in which the entire outlet circulation has to be classified, in this case it is necessary only to intercept a small percentage, for example 1% of the outlet circulation. The tube cleaners are once again entrained in a pumped stream and are reintroduced in order to circulate via the tube bundle under pressure. The tube cleaners are produced so as to have a density such that their ascending force is almost neutral so that they are distributed uniformly through the upper and lower tubes. A tube cleaner may be formed from two components, one component and an ascending-force component. It is possible to restrict the variation in density in response to pressure.
