Title: Heat-cleaning oven and method
IPC: F24C14/02
Filed: 1967-12-22
Abstract: Food soils within a substantially closed gas heated oven are removed by subjecting them to intense infra-red radiation. An oven heated by an upper infra-red burner 31 and side burners 27, 29 is closed save for a flue outlet 33, and the burners are operated to raise the temperature of the gases in the flue outlet 33 to 1050 - 1150 F. and this temperature is maintained for a period during which the side burners or all the burners are turned off. Air is allowed to enter through burners which are turned off, and the burners normally operate with a sufficient excess of air to burn the food soil. Additional small amounts of air may be drawn in through the door seal. The top burner 31 is close to the flue outlet 33 so that any unburnt particles passing to the outlet are subjected to intense infrared radiation before they are exhausted. The cooking operations and the heatcleaning action may be thermostatically controlled. Since the the air used for combustion during heat cleaning is restricted to paths which are subject to the heat of the oven, it becomes preheated.

The thread balloon formed between the traveller and duct 9 thereby rotates around the latter. The yarn in duct 9 is subjected to the action of a jet of compressed air directed thereon by a nozzle 10, the axis of which is disposed at right angles to the axis of duct 9 and in alignment with the axis of a blind resonance bore 11. Various forms of air treatment devices are described.
Patent ES-355594-A1 (ES)
Title: Direct-current transformer having a single common magnetic circuit
IPC: G01R15/20
Filed: 1968-06-28
Abstract: A D.C. to D.C. converter (amplifier) has a single magnetic circuit 3, 4 including two air gaps containing respective magneto-resistive elements 1, 2 which are connected with two other impedances (not shown) in a bridge whose output is amplified and is proportional to the current supplied to an input winding 8, the flux from which is opposed by that produced in a feedback winding 7 by current from the amplifier output the gaps being premagnetized as by magnets 5a, 5b. The magnets may be permanent or electromagnets. The windings 7, 8 are carried on respective core parts 3, 4 which are U-shaped in Fig. 1 or one (3, Fig. 2, not shown) may be formed as a straight bar carrying a single permanent magnet (5) for premagnetization. In this case a single coil (10) carries the input current, and two coils (11) constitute the feedback winding. The straight core member (3) may be made thin (Figs. 3, 5, not shown) so that it saturates to limit the flux through the elements 1, 2 if the input current accidentally exceeds the maximum value of the current in the feedback coil (11), this being limited by the amplifier. The crosssection of the core parts 3, 4 may be reduced (Figs. 5, 6, not shown), and shield plates (12), which may have a lower magnetic grade than the core parts and preferably have a high saturation flux density, are provided to intercept stray flux (Fig. 7, not shown) which could cause premature saturation of the core member (3). The saturable core member (3) may be placed in the same plane as, and between, the core part (4, Fig. 8, not shown) and the plate (12). A constructional arrangement is described for the core (Fig. 9, not shown), and includes, as well as some of the above features, heat conductive, resilient members (25-28) separating core parts and plates. These members may be of copper, one (28) carrying the magnets (5a, 5b) and brass members (30) carry the magneto resistive elements (1, 2). The core is laminated or of tape. Temperature compensation includes making the windings of the same temperature coefficient material and in the case where the feedback winding is in series with a resistance across which an output voltage is taken, this resistance has the same temperature coefficient.

These fingers each have a notch on the underside adjacent to the end connecting with the lands to prevent them shortcircuiting to the edge of the die, and may have a flexible curved section to accommodate changes in length due to expansion and contraction.
Patent ES-371379-A1 (ES)
Title: C-mos dynamic binary counter
IPC: H03K3/356
Filed: 1969-09-10
Abstract: A divider consists of two invertors such as F.E.T.'s 12, 22, a first gate or switch 40 such as F.E.T.'s 42, 44 connecting the output of F.E.T. 12 to the input of F.E.T. 22 and a second gate or switch 30 such as F.E.T.'s 32, 34 connecting the two inputs of F.E.T.'s 12, 22 the input and output voltages being stored during changeover on CA, CB. The switches are enabled alternately. The F.E.T.'s 42, 44 are parallel connected complementary types and are controlled respectively by the clock pulses CP and their complement CP, so that they turn on and off together and eliminate any threshold voltage drop which would arise if only one were used, operating in source follower mode. Similarly, F.E.T.'s 32, 34 operate together, but they are out of phase with F.E.T.'s 42, 44. Preferably the drains of F.E.T.'s 12, 22 a re connected through further F.E.T.'s 14, 24 to the positive supply, 50. When gate 40 is opened by a positive clock pulse CP (and a negative CP), the gate and output line CP1 capacitances C A are charged to the positive supply voltage through F.E.T. 14 provided the voltage on the gate capacitance of F.E.T. 12, C B , is zero. When the clock pulse changes level (Fig. 2, not shown) gate 40 closes and gate 30 opens so that C B is charged from C A , the latter being larger than C B so that its voltage does not drop too much during charging of C A . When the next clock pulse occurs and C P is positive, F.E.T. 12 being turned on by the positive charge on its gate, and its drain thus dropping towards zero, this zero level is transmitted through gate 40 to F.E.T. 22 which is turned off. Thus a square wave CP1 appears at the output having half the frequency of the clock pulses. In an alternative form (Fig. 3, not shown), the drains of F.E.T.'s 14, 15 are connected individually to the corresponding source electrodes of the F.E.T.'s (42a, 44a) in the first gate (40a).

Patent ES-375151-A1 (ES)
Title: The heat stabilisation of oriented thermoplastic films
IPC: B29C48/32
Filed: 1970-01-03
Abstract: A process for the heat stabilization of tubular films of oriented thermoplastic materials comprises feeding such a tubular film filled with gas under pressure through a zone where it is heated to the required heat setting temperature gas being supplied under pressure to the outside of the tube to prevent any undesirable expansion of the tube. As shown, film is extruded from an annular extrusion die 2, to form a tubular film 1, and is cooled by passing over a mandrel 3, and/or through a cooling bath 4. The tube is drawn off by nip rolls 7, whose width is narrower than the collapsed tube, and which are rotating at a greater rate than the extrusion rate, thus forming an air tight seal on the mandrel 3, and preventing the inflation pressure from rupturing the tube at its point of extrusion. The tube is then heated to its orientation temperature by circular infra-red heaters 8, and stretched transversely by the high internal pressure introduced via the pipe 9, and longitudinally by a pair of nip rolls 10, rotating faster than nip rolls 7. The air pressure introduced inside the film can pass through these nip rolls 10 as the said nip rolls do not collapse the film across its entire width. The film passes into the heat treatment zone which consists of a sleeve 11, divided into two compartments. Heated gas under pressure is passed through pipe 13 and the perforations 12 into the upper compartment, surrounding the film and thus balancing the pressure and heating the film to the required temperature. Cold gas under pressure is introduced into the lower compartment through pipe 16 and perforations 18, to cool the film and balance the pressure to prevent expansion due to the high internal pressure. The film passes from the heat treating zone and is finally collapsed across its width by nip rolls 17. In examples polyethylene terephthalate film is heated to a temperature between 150-230 C. during heat setting and film may be so made having an area shrinkage of less than 10% after heating at 140 C. for 1 minute.
