Title: Pivotal connection for keys of a musical instrument
IPC: G10H1/34
Filed: 1967-02-15
Abstract: Keys 5 for a musical instrument comprise a hinge part 1 forced by the spring 12 against the hinge part 6 such that the part 6 contacts the surface 3 on a line 7 extending in the longitudinal direction of the keyboard and contacts the surface 4 at a point located substantially centrally relative to the width of the key. The contacts between the member 6 and the surfaces 3, 4 are provided by rounded elevations 8, 9 and 10. The part 1, which is formed as a metal fillet common for all keys, is secured to the instrument, and is provided with grooves 14 which accommodate pins 13 on the keys to prevent lateral movement of the keys in the regions of the hinge. Lateral movement of the key remote from the hinge is prevented by a lug 17 and rubber ring 16 which move vertically in a cavity (15) (Fig. 2, not shown), in the key. In a further embodiment (Figs. 3, 4, not shown) the rounded contact elevations are formed on the fillet, while the hinge-end of the key is formed with two mutually inclined surfaces defining between them a wedge-shaped space. The keys may be moulded from synthetic material or pressed from sheet steel.

Patent ES-373409-A1 (ES)
Title: Multiple pump power on demand hydraulic system
IPC: F15B11/17
Filed: 1969-11-11
Abstract: A hydraulic actuator 23, Fig. 1 is supplied through a distributing valve 18 by a variable delivery pump 10 until such time as the flow demand of the actuator increases to a predetermined value when the actuator is also automatically supplied by a fixed displacement pump 11 controlled by a valve 25 whereby its output is either zero or at a constant maximum value. With valve 18 closed the pressure rise in a branch line 17 of the delivery line 16, 19 of pump 10 is transmitted through a line 44, a housing bore 42, Fig. 3 and a recess 43 to a cross bore 40 in the hollow valve spool 33 so as to react against a piston 41 to move spool 33 against a spring 34. This results in a branch 45 of the delivery line of pump 11 being connected via a filter 47, Fig. 2, housing recess 29, spool groove 55, housing bore 31 and a line 32 to the drive chamber of pump 11 thereby disengaging a driven cam from the pump piston. Also the pump delivery line 45 is connected to the return reservoir 12 through a housing orifice 61, a bore 58, orifice 62, housing bore 50 and a line 51 and the line 45 is also connected through bores 50, 60 to a chamber 28 thereby assisting pressure in bore 40 in holding the valve spool in its left hand position. On opening valve 18 the shoal 33 will remain in its L.H. position so long as the actuator demand does not exceed the flow capacity of pump 10 and when the demand increases the resultant pressure drop in line 17 causes valve spool 33 to be returned to the R.H. position shown whereby fluid in the drive chamber of pump 11 is exhausted to reservoir 12 through line 32, housing bore 31 grooves 55, 30, spool bores 54, 53, 52, housing bore 50 and line 51 thus rendering pump 11 effective to assist pump 10 in supplying the actuator 23.
Patent ES-376376-A1 (ES)
Title: Single-control mixing faucet and valve for use therein
IPC: F16K27/04
Filed: 1970-01-29
Abstract: A mixing valve cartridge 35, which is adapted to be incorporated in a faucet comprises a base 49, a two-piece cover 51, 53, a valve seat 151, a slidable valve member 175, and an operating mechanism 39, 93. Formed in the end face 139 of base 49 are three ports of which two, the inlet ports, are of identical size and have disposed therewithin sealing rings 140, and of which the third, the outlet port, is larger than the first two and has disposed therewithin a sealing ring 149, all sealing rings project beyond the end face 139 and into recesses formed circumadjacent corresponding ports in the seat 151. Selective communication between the inlet ports and the outlet port is achieved by an annular channel 177 formed in the esat-contacting face of valve member 175, such channel having in the vicinity of the inlet ports a stepped side wall which serves to gradually change the flow direction and hence to minimize noise. The operating mechanism is formed by a bush 93 which is allowed a limited degree of rotation between members 51 and 53 as a result of the provision of mutually engaging lugs (103, 117, Fig. 8, not shown), and of a member 39 which is allowed a limited degree of rocking within the bush by virtue of the provision of stops 135, 137. The valve member is also restricted in its motion by the provision of a tail section 185 which at all times is at least partially disposed between a pair of guides 191, 193. A lubricant containing plastics material layer 199 is provided on the cover-contacting surface of valve member 175. In use, rocking of member 39 from the vertical (fully closed) position places recess 177 in communication with the inlet ports in the seat and also increases its degree of communication with the outlet port. Variation of the ratios of liquids entering the outlet port from each of the two inlet ports is effected by turning bush 93 about its axis, maximum variation being obtained when the valve member has been moved to the position shown in Fig. 11. When mounted in a faucet, the cartridge sealing rings 140, 149 egnage a manifold (21, Fig. 3, not shown), and the assembly is completed by a decorative spout and escutcheon (23 and 37 respectively, Fig. 1, not shown), a single operating lever (41, Fig. 1 ) being mounted on member 39.

Title: Venturi-type devices
IPC: B01D47/10
Filed: 1973-12-26
Abstract: A venturi-type device comprises a fluid flow passage containing in the direction of fluid flow, an upstream section of progressively reducing cross-section, a venturi throat section, and a downstream section of progressively increasing cross-section. The necessary changes in cross-section are produced by a plurality of physical barriers disposed in the passage and spaced from each other transverse to the direction of flow of the fluid, the changes in cross-section being caused by differences in length of the barriers. The barriers may be substantially flat parallel plates disposed longitudinally of the direction of the flow. The surfaces of the barriers may be coated with liquid or solid material. In an exchange device the barriers may be hollow to form other passageways for the flow of a second fluid through the device in exchange relation with the first fluid passing between the barriers.
