Abstract: 1,144,023. Valves. ROBERT BOSCH, G.m.b.H. 9 March, 1966 [10 March, 1965], No. 10244/66. Heading F2V. A pressure relief valve for relieving liquid under pressure comprises a housing 10 containing a cylindrical surface 11 with inlet 18 and outlet passages 20 and an elastic sleeve-like sealing element 12 maintained in sealing contact with the cylindrical surface under the constant pressure of a gas sealed within the housing by a second elastic sealing element 13 acting under the influence of the constant pressure of the gas. The inlet and outlet passages may communicate with annular grooves 17 and 19 respectively in the cylindrical surface. An apertured spacer 16 maintains the sealing element 13 against a plug 14 containing a passage 21 for charging the housing with gas. The housing may also be charged with gas from the inlet and outlet passages. In use when liquid under pressure in an installation to be protected exceeds the constant gas pressure, the sealing element 12 is displaced from the cylindrical surface to establish a connection between the inlet and the outlet passages. In a modification (Fig. 2, not shown), the first sealing element is closed at one end and the outlet communicates with two adjacent annular grooves. In another embodiment (Fig. 3, not shown), the cylindrical surface is provided by the external surface of a cylindrical plug (33) contained within a gas chamber 32 sealed by an annular elastic seal 40.

Abstract: 234,258. Wade, H., (Mills Novelty Co.). April 30, 1924. Keyboard stringed instruments; bows; mutes. -An electrically-operated instrument comprises a set of mechanical violins or the like controlled from a keyboard. The console is provided with switches 12 - - 17, Fig. 7, a keyboard with preferably two banks of keys 20 each key carrying two contacts 30, 31, and pedals 17, 18, 19. Switch 12 by lead 117 electromagnetically puts into action muting devices 121, Fig. 7a, applying lateral pressure to the bridges 122 of the violins. Switch 13 by lead 123 electromagnetically puts into action devices 126 for applying resin to the rotary bows 127. Switches 14, 15, 16 respectively bring into action the first, second and third violins through leads as 66, by electromagnetically closing contacts as 78 in the circuits of the motors 74 driving the " bows " of the instruments. Contacts as 105 in the tremolo circuit of each instrument are simultaneously closed. Depression of a key 20 of the keyboard closes a contact 33 and by a lead 92 electromagnetically depresses both an appropriate finger 98 to stop a string and a rotary bow 127 to sound (if rotating) the same string on each instrument. Further depression of the key closes a contact 39 which by a lead 102 and the already closed contacts 105 actuates the vibrating armatures 109 connected to the tailpieces of the. instruments, producing a tremolo effect. The lefthand (soft) pedal 17 acts through a contact 49 or 50 and lead 115 or 116 to reduce the speed of the bow-motors 74 in operation by introducing successive shunt resistances at the panels 73. The centre (loud) pedal 18 acts through a contact 53 or 54 and lead 113 or 114 to throw in resistances r<2> lower than the normal resistances r, or to cut out the resistances r altogether, thereby increasing the speed of the bow-motors. The right-hand (crescendopedal 19 controls switches 58 - - - 60 in parallel with the switches 14 - - 16, for throwing additional instruments into operation by closing their bow-motor circuits without operation of the switches 14 - - 16. The connections from the lower bank of keys are such as to play notes in the first position on all the strings, with additional upper position notes for the E string. The keys of the upper bank play the same notes as the keys immediately in front of them, but in an upper position; the keys at each end of the upper bank, however, produce the notes in the same way as the corresponding keys on the lower bank.
