Title: Regulating devices governed by fluid pressure
Inventor: SOVICHE GILLES ANDRE PAUL
IPC: F15C1/00
Filed: 1969-12-30
Abstract: 1292977 Fluid-pressure servomotor system ENTREPRISE DE RECHERCHES ET D'ACTIVITES PRETROLIERES ELF and BERTIN & CIE 30 Dec 1969 [31 Dec 1968] 63185/69 Heading G3P A regulating device for controlling the magnitude of a physical entity by means of a modulatable fluidic system comprises a detector 7, a power fluid discharge nozzle 81 having a variable obstruction 43 which delivers a modulated output amplified by two amplifiers 91, 94 and fed to pressure sensitive means 3 responsive to such a signal for controlling the magnitude of the physical entity. Changes in pressure of liquid from chamber 1 are transmitted to a detector 7 giving a mechanical output which alters the position of an obstruction 43 in a proportional amplifier 82, the output of which is fed to the amplifiers 91 and 94. The resulting signal is fed to the valve 3 which controls the fluid from chamber 1. The mechanical output of the detector, Fig.7, determines the rotation of a lever 19 which rotation is transmitted via a wheel 21 and roller 25 to a second wheel 24 coupled to the obstruction 43. The lever 19 has two stable positions: as shown, giving a rotation of the cam surface 43 which increase the output pressure signal in conduit 109 with an increase in pressure in conduit 4; and in dashed lines, giving the inverse effect. With the valve 107 closed, the first stable position operates to give a desired pressure in conduit 4 with variable pressure Po. The second stable position operates to give a pressure in conduit 4 proportional to the pressure Po. With the valve 107 open, the output of amplifier 94 is fed to the controi port of the amplifier 91 so that the control pressure in conduit 109 is either a maximum or a minimum giving an "on/off" operation of the valve 3. Alternatively, an amplifier 91a can be used. The sensitivity of the regulating device is adjusted by a knob 28 which positions the roller 25 relative to the wheels 21 and 24. Proportional Amplifier. A proportional amplifier 82 comprises a nozzle 81, a receiving chamber 85, an obstruction to the jet 43 movable in a channel 88. The obstruction 43 is caused to rotate proportionally according to the movement of a detector of fluid pressure 7, so that the nozzle is masked to a greater and lesser degree. The development of the surface of the obstruction is shown in Fig.9 (not shown).
Patent GB-749380-A (GB)
Abstract: 749,380. Ticket-issuing machines. T.I.M. (TICKET-ISSUE MACHINES), Ltd. June 4, 1954 [June 4, 1953], No. 15484/53. Class 106 (3). A multi-valve ticket printing and issuing machine is provided with a removable recording unit which records the number of tickets issued of a predetermined value. The unit comprises a counter 15, Fig. 5, operated by a ratchet 16 mounted in a movable frame 17 which is pivotable about a spindle 18 carried in a fixed frame 19 which is attached to the interior of the portable machine shown in Fig. 3. Springs 20 urge the spindle 18 into a position where the counter 15 is operative but movement into such a position is prevented by knife-edge detents 21, 22 adjustably secured to the movable frame 17 whose knife edges normally rest on the plane surfaces of a sliding rod 23 and a sliding bar 24 respectively. The rod 23 and bar 24 are provided with notches 25, 26 capable of accommodating their respective knife edges and if the rod and bar are in selected positions the knife edges enter their notches thereby permitting the frame 17 to rotate to bring the counter wheel 16 into the path of a tooth 27 fixed to the operating shaft 8 of the machine. The sliding rod 23 has fixed thereto a yoke 29 which engages in a groove 6 also engaged by a yoke 5 operated by one portion of the fare-setting mechanism and the bar 24 is fixed to a rack 30 meshing with a pinion 11 of the other portion of the fare-setting mechanism. Thus by setting up one value and one value only on the faresetting dial and lever 2 in conjunction with each other the rod 23 and bar 24 are so positioned as to enable a record to be kept of the number of tickets issued of this one value. The detents 21, 22 are adjusted along the rod 23 and bar 24 to set the unit for any predetermined value by means of screwed rods 31, 32 which can be engaged for rotation at recesses 33, 34 in their ends. The upper parts of the detents are provided with datum lines for reading against associated scales. Specifications 368,802 and 598,939 are referred to.

Title: Magnetic-Disk files
IPC: G11B21/02
Filed: 1978-07-26
Abstract: A disk file of the accessing head type has a disk/spindle assembly supported by and within an enclosure wail base, enclosing the assembly about its axis of rotation. The disk/spindle assembly centre of gravity is located on the neutral plane of the base. Actuators for moving the read/write heads of the file are predominantly supported by land lie within the enclosure wall base so that their centres of force lie as close as possible to the neutral plane. This file structure minimises both dynamic and static off-track error resulting from out-of-plane bending of the base due to actuator reaction forces or thermal effects. <IMAGE>

Title: Improvements in Fermentation Processes
IPC: C12M1/04
Filed: 1978-11-20
Abstract: In order to provide an adequate supply of gas to a fermentation process, particularly air or oxygen to aerobic fermentation, there is provided a fermentation process carried out in a fermenting vessel (10). The fermenting broth of micro- organisms in a substrate nutrient liquid is drawn off via a line (1) to a separator (2) from whence the substrate liquid is pressurised by a pump (7) and fed with air or oxygen via a line (8). The gasified substrate is returned to the vessel (10) via a device (9) which controls the pressure reduction at the same time as mixing the substrate with the broth in the vessel (10) to minimise or obviate the release of gas bubbles. Micro- organisms are returned via lines (4) and (5) and drawn off via line (6). Substrate liquid is drawn off via line (11) and replenished via line (12). <IMAGE>
Patent GB-2010708-A (GB)
Title: Rotary bore cutting tools
IPC: B23B51/02
Filed: 1978-12-22
Abstract: A rotary cutting tool for enlarging existing holes has a shank/body portion 30 for rotation relative to a workpiece and a cutter 34 secured releasably and non-rotationally relative to that end portion of the shank which, in use, is remote from the tool holder. The cutter can be made of relatively expensive material such as high speed steel or tungsten carbide and the shank of cheaper material such as structural steel, thus reducing manufacturing costs. The shank may be significantly smaller in cross-section than the diameter of hole produced by the cutter, reducing friction between shank and hole and enhancing coolant flow rates. The shank may have clip cleaving flutes 33 as well as the cutter, and also coolant flow passages 36-39. <IMAGE>

Title: Roll tail sealing machine
IPC: B65H19/29
Filed: 1980-01-04
Abstract: A machine operative for handling a wound web, (30), roll having a loose tail end (31) includes rollers (3, 6) which rotate the roll in the rewinding direction, blowers (14) which unwind the loose tail end off the roll during rotation, and a delivery table (12) upon which the unwound loose tail end settles for the application of glue. A first sensor detects the unwinding of the tail end off the roll and activates a normally deactivated second sensor which turns off the rollers when the tail end reaches a predetermined location on the delivery table. Adhesive is next applied to the stationary tail end by a glue gun (15) which is movably mounted on a pneumatically controlled carriage assembly (17). The glued tail end is thereafter rewound upon the roll, and the roll is subsequently ejected from the machine. A third sensor detects the initial presence of the roll upon the rollers and will initiate ejection of the roll after a predetermined time period elapses, regardless of operation of the glue gun. <IMAGE>
