Title: Improvements in or relating to the treatment of gases containing gaseous impurities
IPC: B01D53/00
Filed: 1965-10-26
Abstract: To eliminate hydrocarbon gaseous impurity or water vapour in a rare gas, the gas with oxygen or water added is passed through a H.F. field causing dissociation of the impurity into hydrogen and carbon, the latter then combines with oxygen to form CO 2 , added water first dissociating to form oxygen. Apparatus comprises a straight or U-shaped silica tube 2 about which two Fe, Cr helices 11, 12 are wound. The helices are connected to a H.F. generator 14 to form external electrodes for a discharge in the tube. To fix the impurity the tube may contain sintered glass particles or dehydrated inorganic zeolite. Oxygen or water is introduced through pipe 18 into krypton or xenon flowing through pipe 20 to the U-tube 2. The gas from tube 2 containing O 2 , CO 2 and H 2 is passed over activated alumina 24 to absorb CO 2 , over heated Cu or CuO to oxidize H 2 to form water vapour and to fix excess O 2 and then through a drier 28 to form water vapour.

Title: Electrical conductor configuration providing length stable with temperature
IPC: H01B12/02
Filed: 1967-12-23
Abstract: An electrical conductor comprises a metal strip in which bending areas are formed to take up longitudinal stresses exerted on the strip so that the conductor may be deformed in its plane in response to thermal expansion or contraction without any change in its overall length when its ends are fixed. As shown, the bending area is formed by making two sets of parallel slots 2 in the conductor blank (Fig. 1, not shown) and bending the blank in its plane until the sides of each slot nearly touch each other. Rectangular notches may be cut out of the blank abreast of the slots so that the overall width of the conductor remains unchanged (Figs. 3, 4, not shown). Alternatively, the conductor blank may be cut to a zig-zag shape and sets of slits are cut parallel to the sides of the angles thus formed (Figs. 5, 6, not shown). The conductor may have a coating, or be provided with inserts in the form of wire, of super-conductive material (Figs. 10, 11, not shown), and a number of such conductors may be stacked within a tube in such a way as to form a central duct for cryogenic fluid (Fig. 7, not shown). Alternatively, the conductors may be stacked in groups insulated from each other to form a polyphase cable. The conductors are stacked with their slotted portions in register. The conductors may be arranged as a coaxial cable. For conventional applications, the conductor may be standard grade copper or aluminium electrolytic aluminium or copper is used for hyperconductivity applications, and, for superconductors, electrolytic aluminium coated with lead, niobiumzirconium, niobium-titanium or niobium-tin alloys.

Patent ES-365679-A1 (ES)
Title: Jk-flip-flop
IPC: H03K3/037
Filed: 1969-04-07
Abstract: In a master-slave J-K bi-stable the inputs of the master bi-stable T 1 T 2 T 1 1T 2 1 are fed from gates G, G1 which respectively receive the signals J, K, Q and clock, and J, K, Q and clock, and the master bi-stable remains sensitive to the J and K inputs during the whole clock pulse and not merely at the beginning thereof. The slave bistable, comprising transistors T 11-13 and T 11 1 -13 1 cross-coupled through transistors T 9 , 10 and T 9 1, 10 1, receives the master output through clock-controlled transistors T 14,14 1 and produces the Q, Q outputs. The cross-coupled transistors T 1 , T 1 1 of the master are switched by the respective parallel transistors T 2 , T 2 1. For example, T 2 conducts (to turn on T 1 ) by current flow to its base from complementary transistors T 7 , T 8 provided that: clock pulse T is positive to hold T 7 T 8 on, and neither T 4 nor T 5 of gate G conducts to divert this current from T 2 . The bases of T 4 , T 5 are connected to the collectors of transistors T 3 , T 6 which receive input signals thus: K at T 3 base, Q at T 3 collector and T 6 base through R 1 and R 2 , and J at T 6 collector. In the similar gate G1, parallel transistors T 4 1T 5 1 and their associated transistors T 3 1T 6 1 receive input signals thus: J at T 3 1 base, Q at T 3 1 collector and T 6 1 base through R 1 1R 2 1, and K at T 6 1 collector. The master transistor T 1 only turns on if, during the clock pulse, J is 0 and Q is 1, or K is 1 and Q is 0 and T 1 1 turns on if, during the clock pulse, K is 0 and Q is 1, or J is 1 and Q is 0. When the clock pulse ceases to be positive the input gates G, G1 to the master are blocked, and the master sets the slave. Set and reset inputs for master and slave are provided at S, S1. In a modification (Fig. 3, not shown) the transistors T 4 T 5 and T 4 1T 5 1 of gates G, G1 are connected to the master bi-stable T 1 T 1 1 through clock controlled transistors T 18 T 18 1. The master transistors T 1 T 1 1 have base diodes D 1 D 1 1 and do not have the parallel transistors T 2 T 2 1.
Patent ES-367756-A1 (ES)
Title: Pneumatic piston return system for impact tools
IPC: B25C1/04
Filed: 1969-05-27
Abstract: In a pneumatically operated device e.g. a stapling machine, a piston 36, Fig. 1, is driven by compressed air, controlled by a spool valve 90, in a cylinder 34 connected by holes 63 with an annular chamber 62. This chamber is for containing compressed air to return the piston 36 when the space 82 above the piston is relieved by the valve 90. The spool valve 90, in the position shown in Fig. 1, closes the space 82 above the piston 36 from the compressed air in air inlet chamber 84, and connects the space 82 with the atmosphere through an outlet 112. The valve 90 is lowered by the differential action of the compressed air in the inlet chamber 84 whilst a ball valve 120 is held in its uppermost position by a trigger 110 to cut off the space 94 below the spool valve 90 from the compressed air. In its lower position the valve 90 closes the outlet 112 and allows compressed air to enter the space 82 causing the piston 36 and driver 38 to perform its drive stroke. Different embodiments comprise different constructions allowing the compressed air to enter the annular chamber 62. The piston 36 and annular chamber 62 have 0-rings 60, 70 mounted in grooves, either of which 0-rings may have notches cut out of its lower face, Fig. 6 (not shown), or may have projections on its lower face, Fig. 8 (not shown). These constructions allow compressed air to leak past the O- ring when it is resting on the lower edge of its grooves. In an embodiment in which the piston 0-ring has the notched construction, compressed air can leak past the piston 36 and into the annular chamber 62 during the downward stroke and whilst it is stationary at the bottom of the cylinder 34. However when the piston is returned by the compressed air below the piston and in the annular chamber 62 the O-ring 70 then abuts the upper edge of its groove. Channels 130, 132 are provided to remove any residual compressed air below the piston when at the upper end of the cylinder 34. In an embodiment in which the annular chamber O-ring has the notched construction, Fig. 11, compressed air passes through passages 332, 333, and around the O-ring 270 during the downward stroke of the piston and whilst it is stationary at the bottom of the cylinder. However the annular chamber is sealed when the pressure above the piston and 0-ring 270 is relieved. In a further embodiment, a passage (523), Fig. 12 (not shown), connects the annular chamber 62 with the inlet chamber 84 when the valve 90 is in its lower position, and is shut off from the compressed air when the valve 90 is in its upper position.

Patent ES-413663-A1 (ES)
Title: Fuel pump and drive therefor
IPC: F02M41/14
Filed: 1973-04-13
Abstract: An inlet metering fuel injection pump for pressurizing metered charge of fuel to high pressure is provided with an independent helical gear driven drive shaft having its drive connection with the distributor rotor disposed concentrically with the governor flyweights. The shaft is mounted by a ball bearing received within a deep bearing recess of the housing in which the bearing cannot bottom. The bearing is axially fixed to the shaft and is axially slidable in the bearing recess. A wave washer engages the outer race to bias the shaft toward the distributor rotor to prevent axial oscillations of the shaft and the resultant pumping and pressure pulsations in the fuel which fills the pump housing as torsional loading on the shaft suddenly changes. This eliminates any instability of operation due to to-and-fro flow of fuel past the governor weights and pulsations of pressure acting on the plungers of the charge pump.

Title: Constant velocity torque transmitting universal joint
IPC: F16D3/223
Filed: 1974-04-25
Abstract: A universal joint comprises a tubular outer joint member having a plurality of grooves therein and a concave spherical surface within which is moveably mounted a cage having a plurality of openings in which balls are positioned. The inner surface of the cage is provided with a concave spherical opening within which is moveably mounted an inner joint member having circumferentially spaced grooves there around. Each ball is located in opposed grooves of the inner and outer joint members and the balls are disposed in a plane passing through the axes of the outer and inner joint members. Because of play in the joint brought about by manufacturing tolerances the balls are subjected to a force which displaces the balls from the homokinetic plane. Means are therefore provided on a member of the joint which either coacts with the balls or another member of the joint to increase the angle between the plane passing through the balls and the axis of the inner joint member to control the alignment direction of the balls.
