Patent ES-429438-A1 (ES)
Title: Object sensing apparatus
IPC: B65H63/02
Filed: 1974-08-22
Abstract: Apparatus for sensing the presence of an object, such as a machine operator, in the path of 1 travelling tender is disclosed. The tender is movable by drive means relative to a strand processing machine and incorporates a source of electrical energy and means in circuit with the electrical energy source to provide a modulated output signal. Radiant energy emitting means are provided for receiving the signal and providing a radiation output proportional to the signal. Radiation sensitive means for receiving the output from the emitting source and transmitting a control signal in response thereto is also included. The control signal is measured by a comparator and gating means are connected with the comparator, the gating means being in a normally non-conductive state. The gating means is switched to a conductive state to program the tender drive means to a zero speed state to program the tender drive means to a zero speed state when the amplitude of the control signal drops below a predetermined value such as, for example, when the operator interrupts the output signal from the output signal producing means. In consequence thereof the travelling tender is halted without injury to the operator.

Patent ES-478884-A1 (ES)
Title: Liquid fuel injection pump
IPC: F02M41/14
Filed: 1979-03-22
Abstract: A fuel pumping apparatus includes an injection pump to which fuel is supplied by a low pressure supply pump. A shuttle located in a cylinder has one end connected to the injection pump and the other end to the supply pump when it is desired to feed fuel to the engine. The movement of the shuttle represents the amount of fuel supplied to the injection pump and this movement is measured and the signal supplied to a processing circuit which also receives a demand signal. The movement of the shuttle is halted by the gradual closure of communication between the one end of the cylinder and the injection pump. This is achieved in the example by a passage moving out of registration with a port. The rate of flow of fuel from the pump to the cylinder is controlled by a fuel control device the setting of which is determined by the processing circuit which strives to ensure that the actual amount of fuel supplied to the injection pump is equal to the desired amount.

Title: Method of and apparatus for the degasification of circulation systems for liquids
IPC: B01D19/00
Filed: 1979-06-08
Abstract: In a closed circulation system containing a constant amount of liquid, a force is generated for driving the liquid through the system.
