Patent ES-371241-A1 (ES)
Title: Food smoker has closed circuit with smoke cleaning - and concentration control
IPC: A23B4/052
Filed: 1969-09-05
Abstract: Chamber is supplied with smoke from a producer next to it by a line which circulates the smoke in the chamber until it is drawn off the far side. The line linking producer and chamber turns 180 degrees at least and has baffles so that tar components precipitate onto these and thus clean the smoke feed as a function of the number of pipe elbows and overall pipe length. The line leading from the producer enters the chamber as a down-comer and runs some way with the chamber circulating line for better smoke entrainment. If the smoke does not require cleaning, for instance when piping a hot pure gas, the producer can be directly coupled to the chamber by a gate or other slide thus eliminating the devious cleaning part of the pipe. Heating means composed of electrical resistances in this part of the line heat up the incoming smoke for steaming the food if this is required. Heaters provide independently above and below the wood shavings grate maintain this in flowing condition and prevents its ignition, thus maintaining optimum smoke output. The producer and return from the chamber can be mixed to provide a balanced smoke for treating the chamber product.

Patent ES-382143-A1 (ES)
Title: Simulation timing control system
IPC: G06F17/50
Filed: 1970-07-23
Abstract: A simulation system comprises one or more digital computers CPa, CPb having a program to be tested and a digital simulation computer CPd programmed to simulate peripheral units in activity wherein the computers CPa, CPb can be driven by the clock pulses MCX of computer CPd. This ensures that the simulation computer can operate at the same speed as the test computers while testing their programmes which is difficult to ensure if computers CPa, CPb are controlled by their own clock sources. Simulation.-The programme(s) to be tested are loaded into the or each computer CPa, CPb and a simulation programme is loaded into the computer CPd, which simulation programme sends data representing peripheral units in activity, e.g. for a telephone exchange system in real time, to the computer(s) CPa, CPb, receives output data from the computer(s) CPa, CPb, checks its correctness and sends further data. The computer CPd usually prints all the data. Operation.-The computer CPd is controlled by clock pulses MCX which are also sent to an AND gate pt controlled by a bi-stable MA. When gate pt is enabled it sends clock pulses CK to AND gates pb, pc controlled by respective bi-stables MB, MC, and, if these are enabled, clock pulses are sent to control the computers CPa, CPb whose own clock sources HGa, HGb are cut off for the period of the simulation by switches ca, cb. The bi-stable MA can be set to 0, hence interrupting the computers CPa, CPb, by the computer CPd, by detectors DT and DS, or a counter CIG. The counter CIG can cause interrupt after a predetermined count (of clock pulses) set by computer CPd. Detector DT causes interrupt when either computer CPa, CPb provides an input/output and detector DS causes interrupt in case either computer itself has an internal interrupt. The bi-stables MB, MC are set by computer CPd so that one of the computers CPa, CPb can be interrupted while the other continues operation.

Patent ES-422008-A1 (ES)
Title: X-ray contrast detection system
IPC: G01V5/00
Filed: 1974-01-04
Abstract: The invention relates to a technique for monitoring objects such as parcels or luggage for the presence of a predetermined class of objects, such as guns and bullets, on the basis of contrast detection of transmitted high energy X-rays. An object to be analyzed is subjected to high energy x-ray in a range of 200-400KeV and a plurality of detectors are utilized to monitor the variation of transmission of various portions of the object. Signals developed by the detectors indicative of the x-ray transmission characteristics of the various portions of the object are applied to signal processing circuitry which is adjusted to generate an output signal if any of the detectors produce a signal of a value indicative of a gun or bullet. In the absence of a gun or bullet substantially all high energy x-ray is transmitted through the object and detected by the detectors thus resulting in relatively high signal output from the respective detectors. If, however, a gun or bullet is present within the object, a substantial portion of the high energy x-ray radiation will be absorbed by the gun or bullet thus resulting in a relatively low level signal output from the detectors monitoring that portion of the object within which the gun is located.
