Title: Hydropneumatic Accumulator
Inventor: PACKER MARTIN RICHARD
IPC: F15B1/24
Filed: 1967-09-15
Abstract: 1,183,477. Hydraulic accumulators. HYDROTROLE Ltd. Sept.13, 1968 [Sept.15, 1967], No. 42061/67. Heading F1P. An hydraulic accumulator comprises a cylinder 42 divided by a piston 100 into an upper gas chamber 41 and a lower liquid chamber 43, the piston incorporating a resiliently deformable partition 112 arranged to absorb shock increases in the pressure of the liquid not immediately absorbed by movement of the piston. The piston is in the form of two parts, 102, 106 screwed or bolted together with the partition sandwiched therebetween. The piston parts 102, 106 have inwardly tapering bores which support the partition when in one or other of its extreme positions. Gas is supplied to the gas chamber through a connector 58 mounted in a cylinder end closure plate 46 having communicating radial and axial openings 48, 50 for passage of gas from the connector to the chamber. The piston 100 seats on an annular deformable member 78 when the accumulator is fully discharged and a protuberance 146 on the end closure plate 66 enters an opening 142 in the piston. A ring of liquid (90, Fig. 2, not shown) may be arranged to become trapped between the piston 100 and the member 78 thereby to form a seal to prevent gas escaping round the piston and into the liquid chamber. The plate 66 may be provided with a sub-plate (127, Fig.3, not shown), arranged to retain a plug (126) in a bore (123). Should the sub-plate be removed for maintenance with gas chamber charged the plug falls out and the partition extrudes through the bore (123). The gas chamber may be in continuous communication with a gas reservoir.

Abstract: 932,437. Assembling force fits. MEZ MOHELNICE NARODNI PODNIK. Dec. 9, 1960 [Dec. 9, 1959], No. 42623/60. Class 83 (4). An automatic horizontal hydraulic press for pressing shafts into rotors, comprises a set of three working cylinders, namely a centering cylinder with a plunger carrying a centering sleeve, a bearing cylinder with a plunger and forming a unit with said centering cylinder, and opposed to said unit and located on the opposite side of the press, a pressure cylinder with the working plunger thereof carrying a centering extension, and between said working cylinders a rotor tilting bed and a shaft bed provided with automatic feeding and withdrawing equipment controlled by pneumatically and electrically synchronized movements of the plungers of the working cylinders. The press comprises a base frame 105 supporting a pressure cylinder 1, a bearing cylinder 3 and a centering cylinder 5. In the middle of the base frame is fixed a shaft bed 17, 18, and an adjustable tilting rotor bed 16, 25. Attached to the pressure plunger 2 is a guide stirrup 20 movable along a guide rod 19. Similarly, a guide stirrup 21 is attached to the bearing plunger 4. Stops on the guide stirrups engage adjustable limit switches on a bearer 111. A rotor magazine 13 is attached to the stationary part 25 of the tilting rotor bed and the tilting part 16 is operated by means of a segment 26, a rack 27 and a pressure cylinder 11. Adjacent the tilting rotor bed is a magazine 15 for pressed-in rotors. Both magazines and the tilting rotor bed are adjusted by means of chain-and-sprocket gearing. The shafts 102, Fig. 3, are intermittently fed into centering sleeves 28 mounted on spring-loaded supports 31 which carry rollers 29 for engaging the press plunger 2 so that the shafts support is forced down into its lowest position, thus making free the path of the press plunger 2. The operation of the press is fully automatic, the intermittent feed of the shafts into the supports 28 of the shaft bed 17 and the rotors into the rotor bed 16 being controlled by pneumatic slide valves and electric switches, the circuitry of which is fully described in the Specification. As the plunger 2 moves forward the shaft 102 is centered by a sleeve 22 and a supporting insert 23 on the bearing cylinder plunger engages the rotor 103 and adjusts its position in the press. As the plunger 6 of the centering cylinder moves forward a centering sleeve 24 enters the aperture in the rotor and a central hole in the sleeve receives the free end of the shaft 102. Finally, the pressure plunger 2 presses the shaft into the rotor after which the pressure plunger and centering plunger automatically return to their initial positions, the tilting plate 16 of the rotor bed opens and the rotor with the shaft pressed therein rolls into the magazine 15 and a limit switch initiates a repeat of the whole cycle, A safety switch 38 is incorporated to stop the press should the limit switch of the front position of the bearing cylinder fail to switch off.

Abstract: 1,200,287. Driving detaching cylinders of combing machines. HISPANO SUIZA (SUISSE) S.A. 13 Sept., 1968 [26 Sept., 1967], No. 43589/68. Heading D1N. A detaching cylinder 1 of a combing machine is carried by a support 1a driven with an alternating movement perpendicular to the axis of the cylinder in the directions F and is driven with an unsymmetrical oscillating rotational movement, having an amplitude A 1  in the delivery direction greater than the amplitude A 2  in the opposite direction. The oscillating rotational movement of the detaching cylinder 1 is derived from a helical pinion 2, coupled in rotation with the cylinder 1, which is rotated by its constant contact with a cylindrical control rack 4 whose axis is orthogonal to that of the pinion. The rack 4 has simultaneously imparted thereto by two control devices CR and CT a rotational movement and a reciprocatory, axial, linear movement. Control device CT, which may be hydraulic, electric or mechanical (as shown) imposes on the rack a reciprocating movement whose amplitude is such that the corresponding theoretical rotational movement of the detaching cylinder (i.e. the movement it would undergo if subjected solely to this control) is a symmetrical oscillating movement having an amplitude equal to (A 1 + A 2 ). The control CR im- 2 poses on the rack a movement of continuous rotation whose direction corresponds to the delivery rotational direction of the detaching cylinder and whose angular speed is such that the corresponding theoretical movement of the detaching cylinder is a movement of continuous rotation which, during a time lapse equal to the duration of a single linear stroke of the rack (in either direction), has an amplitude of (A 1 -A 2 ) / 2. The two controls may be actuated from a common drive shaft 5. The linear control CT consisting of an eccentric plate 7 fixed to the shaft 5 and coupled via a rod 8 to a slider 9 mounted on a shaft 10, the slider also being rigid with an axial thrust bearing 11 in which the rack can rotate. The amplitude of the stroke is regulated by movably housing the rod end in a slot 12 of the plate. The rotational control CR comprises a toothed cylinder 17, meshing with a pinion on the rack, driven by a transmission gearing 13, 14 from the shaft 5.
