Patent ES-341725-A1 (ES)
Title: Air cooling and dehumidification systems
IPC: F24F3/14
Filed: 1967-06-13
Abstract: The expansion valve means of a refrigeration system for conditioning air is controlled so that when the humidity of the air is above a predetermined value the evaporator is supplied with refrigerant at such a rate that a portion of the evaporator is starved and the remainder operates at a temperature lower than the dew point of the air. Only part of the air passing over the evaporator is thus cooled and dehumidified and reheating of the air is stated to be unnecessary. As shown, the system comprises a compressor C, reversing valve RV, outdoor and indoor heat exchangers 12, 14 with respective fans OF, IF, a liquid line 17 having a portion 18 disposed in a suction line accumulator 19, a two-way valve 23 and a main expansion valve 21 in series downstream of portion 18 and an auxiliary expansion valve 34 in parallel with valves 21, 23. When indoor coil 14 is operating as the evaporator and air humidity is low, the compressor, fans and valve 23 are controlled thermostatically and, when valve 23 is open, valve 21, which is responsive to liquid refrigerant temperature and pressure in line 17, overfeeds coil 14. Excess refrigerant is evaporated in accumulator 19. When the air humidity is high, valve 23 is closed and valve 34 opens at a predetermined low evaporator outlet pressure to supply refrigerant at the rate discussed above. In a modification (Fig. 4, not shown), valve 23 is omitted and valve 21 is closed when humidity is high by energizing a heater which encircles the temperature sensing bulb 46 of the valve. Electric circuitry and switching arrangements (Figs. 2a-2g, 3 and 5, not shown) for operating the system in the above manner are described and examples of operating temperatures are given.

Title: Isotope exchange between a deuterated gas and ammonia
IPC: C01B4/00
Filed: 1967-07-15
Abstract: In a process for deuterium exchange between NH 3 and H 2 wherein liquid NH 3 is enriched in D by countercurrent contact with gaseous N 2 + H 2 in 2 towers (T 1 and T 2 ) then cracked (at C) to give N 2 + H 2 for passing through T 2 , and the gases from T 1 are synthesized (at S) to give NH 3 for passing to T 1 , product low-D NH 3 being withdrawn after S and high-D NH 3 after T 2 , and N 2 + H 2 feed being introduced between T 1 and T 2 T 2 and optionally also T 1 is operated at a pressure at most equal to that of the gases leaving C. Where only T 2 is at a low pressure, the gases may leave C at 50-60 bars, leave T 2 at 40- 50 bars, be compressed to 360-410 bars between T 2 and T 1 , and leave T 1 at 350-400 bars then after synthesis, the NH 3 is expanded between T 1 and T 2 (Fig. 2). Where T 1 and T 2 are both at a low pressure, the gases may leave T 1 at 30-10 bars and be compressed to 350-400 bars between T 1 and S. Alternatively, T 1 , T 2 and C may each operate at 100 bars and part of the gases leaving T 1 may be synthesized at 100 bars (in S 1 ) and recycled to T 1 , the remainder being compressed to 250-500 bars, synthesized (in S 2 ) and withdrawn (Fig. 4). S 1 and C may operate in heat exchange relationship (Fig. 5). The use of an amide catalyst is referred to.
Patent ES-344364-A1 (ES)
Title: Fluid system for independent operation of two fluid motors
IPC: G05D11/02
Filed: 1967-08-23
Abstract: In an hydraulic transmission in which an engine-driven variable-displacement pump 16 supplies pressure fluid to two independently controlled fixed-displacement motors 11, 14, driving, for example, the mixer drum D and a centrifugal pump 10 supplying water thereto, respectively, on a mobile cement mixer, the displacement of the pump being controlled by a piston 17 spring-biased to a maximum flow position and operated by a fluid pressure differential sensed across a manually adjustable restrictor 30 in the return line of the motor 11, a further manual forward/reverse and by-pass valve 29 controlling the motor 11, the control 35 for the motor 14 includes a sequence valve 36 which normally allows flow to line 31 but is responsive to fluid flow requirements of motor 14 to restrict or prevent flow to the motor 11 when the combined flow through motors 11 and 14 exceeds the output of the pump 16. With motor 11 operating, if a valve 40 is opened to initiate operation of motor 14, the valve 36 tends to close causing the motor 11 to slow down or stop until the pump output is increased sufficiently to bring the motor 14 up to its operating speed, when the valve 36 again opens. As shown, the control 35 for the motor 14 also includes a manually operated, shut-off valve 40, e.g. of the needle valve type, which effects the selective operation of the motor 14, a flow control valve 39 being preset to limit the maximum speed of the motor 14, e.g. to limit fluid flow through the motor to a maximum of seven gallons/minute. Again, Fig. 2 (not shown), the shut-off valve 40 is replaced by a second sequence valve (43) and an electric solenoid-operated, shut-off valve (44) included in the control line (46) of the valve (43), which line also communicates with the motor 14 return line (20a). The line (46) is also connected to the input port of the sequence valve (43) through a restrictor (47) so that, with the shut-off valve (44) closed, pressure builds up in line (46) to close valve (43) and prevent operation of motor 14 and, on opening valve (44), control pressure (46) falls allowing valve (43) to open and motor 14 to operate.
Patent ES-344812-A1 (ES)
Title: Improvements in or relating to a stop motion device for a machine carrying a thread supply
IPC: D03D47/00
Filed: 1967-09-07
Abstract: A stop motion for a machine such as a shuttleless loom in which a weft thread is drawn intermittently from a supply is operated on cessation of an electric signal produced by the running of the thread over a sensing element during a thread detection period. The senser is preferably of the piezeoelectric type, Fig. 8, in which the thread runs in a slot 21 on a rod 23 of piezeoelectric ceramic material held between springs 24, 25. A high frequency electric signal of the order of 30 kilocycles is produced in the cable 32. This signal is applied to the circuit of Fig. 1, first passing through three amplifier stages TR1, TR2, TR3 to give a signal in the form B. This amplied signal then passes to a circuit TR4-TR7 which controls a relay 20 in the machine circuit to stop the machine on cessation of the signal at A on breakage of the thread. To ensure that the relay 20 is not operated during the periods between weft insertions when the thread is not being withdrawn a mechanical switch 30 driven by the machine controls the circuit TR4-TR7. In addition a parallel photoelectric circuit 40, operated by a member 50 attached to the weft inserter, also controls the relay 20 to ensure that, on release of the thread at the selvedge, the relay 20 is not operated. Other forms of senser may be used such as a piezoelectric generator of the crystal type, a photoelectric signal generator, a resistance signal generator or a capacitor signal generator.
Patent ES-345220-A1 (ES)
Title: Method of synchronization in binary communication systems
IPC: H04J3/06
Filed: 1967-09-20
Abstract: In a digital communication system such as a time division multiplex p.c.m. system, at the transmitter the digit pulses are derived from a train of bipolar rectangular oscillations whose fundamental frequency is equal to half the bit frequency and synchronizing pulses are inserted in antipolar relation to the rectangular oscillations. Fig. 1 shows channel 24 and channel 1 of an 8-bit signal to be transmitted, the gap between channels 24 and 1 being left for a sync. pulse to be inserted. In Fig. 3 the rectangular wave is indicated by dashed lines, respective half-waves being blanked out for each binary 0 and the half-wave (positive or negative) being transmitted for each binary 1. A sync. pulse is inserted as shown with a polarity in opposition to that of the corresponding half-wave of the rectangular oscillation. At the receiver, Fig. 4, the sync. pulses are separated by adding to the received pulses a rectangular wave (shown by dashed lines) similar to but of opposite phase to that used at the transmitter. This results in the sync. pulses being double the amplitude of the signal pulses so that they may be separated by a threshold circuit, Fig. 5 (not shown). A plurality of sync. pulses may be distributed throughout each frame and the receiver provided with an integrating circuit which only transmits a signal after a predetermined number of sync. pulses have arrived.

Patent ES-403853-A1 (ES)
Title: Safety control valve system for fluid actuated devices
IPC: B30B15/14
Filed: 1973-06-14
Abstract: Two normally closed three-way main valves are connected in series to supply fluid to an outlet port. When moved to their closed positions, the valves provide parallel connections from the outlet port to exhaust. Therefore, if either valve is stuck in an open or partially open position, movement of the other valve to its closed position will provide good exhausting capacity. Furthermore, there will be no substantial pressure at the outlet port until both valves are actuated to their open position. Movement of either valve to its exhaust position will completely stop the supply of air to the outlet port and provide a direct exhaust connection.
