Inventor: MILLER WILLIAM JOSEPH
IPC: C03B9/195
Filed: 1918-08-08
Abstract: 130,986. Miller, W. J. Aug. 11, 1917, [Convention date]. Moulding under pressure; removing articles from moulds; cutting off excess of metal.-Relates to apparatus for discharging the finished glassware from the moulds of a press. The moulds E are carried on trunnions 20 on a frame D, which is rotated step by step by a fluidpressure cylinder &c. 37. The gatherer places the charge in the mould and presses the punty upon a. valve which starts the machine, after which the cycle of operations is completed automatically by fiuid-pressure mechanism. Shears cut the depending charge from the punty and the charged mould is carried round to the pressing station, where the plunger descends and compresses the charge. The further rotation of the frame D causes a rod 27 to strike a cam 36 and so raise the mould top 34, which it supports. A toothed arc 21 on the mould E engages another toothed arc H, which is swung downwards by a fluid-pressure cylinder &c. 95, and so inverts the mould and discharges the finished article into an annular trough 87 containing sand &c. to cushion the fall. The tappets of the slide valve controlling the fluid pressure supply to cylinder 95 are operated by a block fixed to the piston-rod 38 of cylinder 37. The annular trough 87 is rotated intermittingly in unison with the frame D so that successive articles do not fall upon one another. The trunnions 20 are off-set, so that the mould E turns back to its normal position by its own weight when disengaged from the arc II, and a stop 22 keeps it upright.

Title: Apparatus for determining the consistency of concrete mixtures
IPC: G01N11/00
Filed: 1947-07-23
Abstract: 639,670. Testing concrete. KOEHRING CO. July 23, 1947, No. 19813. Convention date, Nov. 9, 1938. [Class 106 (ii)] [Also in Group II] The consistency of concrete in a rotating mixing container is determined by measuring the shift of the centre of gravity of the contents of the container due to the tendency of the mixture to accumulate in one location when it lacks uniform moisture and for the accumulated mass to become redistributed as the moisture content becomes more uniform. In one embodiment, the tilting means 5 is coupled to the bearing member 7 through a link 8 formed with an indicator 11 which moves across a scale 12, the indicator being loaded by a spring 12 in a dash-pot 13. As the consistency of the mixture becomes more uniform or is made wetter the level of the contents tends to shift as from 24 to 25 the downward thrust upon the link 8 being reduced to cause the indicator to move upwards.

Abstract: 1,140,213. Rotary hydraulic motors. EXPERIMENTALNY NAUCHNO-ISSLEDOVATELSKY INSTITUT METALLOREZHUSCHIKH STANKOV. May 5, 1966, No. 19936/66. Heading F1F. A reversible rotary hydraulic motor of the outwardly-sliding radial vane type comprises an abutment ring or stator 3 lodged in casing 1 between a fixed cheek-plate 5 and an axially-movable pressure-loaded cheek-plate 6, the inner-peripheral surface of the stator having a two-lobed profile, Fig. 2 (not shown), so that it defines with a rotor 4 of circular profile two crescent-shaped working- chambers whose ends are connected to inlet and outlet passages 16, 17 for working liquid by arcuate ports (19, 36),Figs.3 and 4 (not shown), in the plates 5, 6, respectively, and passages 18, 33 in the casing 1 and the plate 6, respectively. When the motor is started, vanes (10) slidably lodged in the rotor are rendered in close proximity with the stator by a pair of two-lobed cams 11, 12 attached to the plates 5, 6, respectively; thereafter, the vanes are held in contact with the stator by centrifugal action and the pressure of liquid in a cavity 35 within the rotor. Said cavity communicates with a pressure-loading chamber 21 for the plate 6 through an axial bore (34), Fig. 5 (not shown), in said plate and is constituted by annular channels in the side faces of the rotor and the radially innermost ends of slots containing the vanes (10). When working liquid is supplied to the motor through the passage 16, the inlet pressure of said liquid is transmitted to the chamber 21 through arcuate ports (20) in the plate 6, which are axially aligned with the ports (19) in the plate 5, passages (26, 27, 28) in the plate 6, an axial bore 24 in the plate 6 containing a valvemember 30 abutting a fixed plug 32, and further passages (22, 23), Fig. 6 (not shown), in the plate 6. One end of the passage (22) also communicates with the cavity 35. When working liquid is supplied to the passage 17 to reverse the direction of rotation of the rotor, the liquid in the passage 33 enters the bore 24 through passages 25 in the plate 6 and moves the valve-member 30 until it abuts another fixed plug 31 to prevent communication between the passages (26, 27, 28) and the passages (22, 23) and allow liquid in the passages 25 to flow through the bore 24 into the passages (22, 23) so as to subject the chamber 21 to inlet pressure. The radially or axially outermost ends of the passages (23, 26, 27, 28) are closed by fixed plugs. Initial loading of the plate 6 is effected by compression springs 29. Leakage liquid lying a space between bearings 8, 9 for a power-output shaft 7 escapes through a passage 38. The profile of each of the cams 11, 12 comprises two pairs of diametrally-opposed part-circular portions, Fig. 7 (not shown), that are concentric with similar portions of the profile of the innerperipheral surface of the stator, said portions of the cam profile being connected to one another by straight lines that do not match the corresponding arcuate portions of the profile of said surface.
