Title: Diaphragm clutch
IPC: F16D13/58
Filed: 1968-03-28
Abstract: 1,204,539. Friction clutches. SOC. ANON. FRANCAISE DU FERODO. 28 March, 1968 [31 March, 1967], No. 15016/68. Heading F2C. In a friction clutch having a driven plate 16 engaged between a driving flywheel 12 and a presser plate 15 by a diaphragm spring 18, the usual fulcrum rings, arranged one each side of the diaphragm spring on spacer rivets secured to the clutch housing, are replaced by forming the heads of the spacer rivets 25 and the clutch housing 10 with shaped concentric abutments 23 and 24 respectively serving as fulcrum points for the diaphragm spring 18. As shown, and in an alternative embodiment (Figs. 4 and 5, not shown) the spacer rivets 25 are stamped to form the arcuate fulcrum bead 26 on their heads 23, the rivet shanks 28 being formed square (as shown) or oval &c. to engage correspondingly shaped holes in the clutch cover for correct angular location of the rivets such that their arcuate beads 26 are centred with respect to the clutch axis (A) (Fig. 2, not shown). As shown, the diaphragm spring 18 is arranged between the clutch cover 10 and the pressure plate 15, whilst in an alternative clutch arrangement (Fig. 6, not shown) the clutch cover is arranged between the pressser plate and the diaphram spring, the latter being mounted externally of the clutch assembly on the beaded rivets, a single fulcrum ring, free or welded to the cover, being employed between the diaphragm spring and the cover.

Title: Temperature control for air blending heating system
IPC: F24F11/00
Filed: 1949-06-08
Abstract: 663,006. Automatic temperature control sys-  tems. VAPOR HEATING CORPORATION. June 8, 1949 [June 17, 1948], No. 15307/49. Class 38 (iv). The temperature in an enclosed space 11 is maintained within predetermined limits by a thermostat A having an auxiliary heater 46, the current supply to which may be varied. The thermostat A is also provided with a grounded mercury column 30 and spaced contacts 28, 29 defining the lower and upper temperature limits respectively. When the mercury column is between the contact 28, 29, the auxiliary heater is fed through a resistance 47, conductor 37 and contacts 33, 34 of an energized relay 35. Under these conditions a further relay 31 is byepassed and is de-energized. If the temperature falls, the mercury column falls below the contact 28 and relay 31 becomes energized, thereby applying full current to the auxiliary heater 46 via relay contacts 50, and energizing a field 44 of a motor 27 through contacts 42. The motor 27 operates a valve 22 controlling the proportion of hot and cold air flowing through ducts 16 and 15 respectively, and through duct 21, into the space 11. If, however, the temperature of the space rises, mercury column 30 rises above contact 29, thereby de-energizing both relays 31 and 35. All heating current is thus shut off from the heater 46 and the motor 27 is energized in the reverse direction by means of a field 44a energized through relay contacts 33, 57. An outside thermostat B is also provided controlling a relay 80. The relay 80 has contacts 78, 79 through which additional heating current to the heater 46 normally passes. If, however, the outside temperature falls below a predetermined value the relay 80 becomes energized, thereby energizing an auxiliary heater 90 on the thermostat B and breaking the circuit to the heater 46, causing the level of the mercury column in the thermostat A to fall, thereby increasing the heating periods of the space 11. A third similar thermostat C controlling a fourth path to the heater 46 and responsive to the temperature of the duct 21 also causes increased heating periods when the temperature in the duct 21 falls below a predetermined value.

Abstract: 993,476. Turbines. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. March 10, 1964 [April 17, 1963], No. 15101/63. Heading F1T. At least one ring of interstage guide blades of a turbine is provided with encircling shroud members having inner surfaces provided with openings arranged to intercept and to permit the outward passage of erosive particles travelling along these inner surfaces. The invention is described with reference to a double-flow steam turbine, Fig. 1 (not shown), having two axially-opposed working medium flow passages in each of which are disposed five rings of rotor blades 9 or 10, a further ring of rotor blades 12 at the downstream end of each flow passage and, between each two rings of rotor blades, rings of guide blades 13, the downstream ring of which is designated 13L. In each flow passage, one ring of guide blades 13 is mounted in a diaphragm 25, Fig. 2, including a shroud ring 27 to which is secured a substantially cylindrical shroud plate 29. Near the shroud ring, the shroud plate 29 is provided with slots 39 spaced apart axially and overlapping circumferentially. Water adhering to the inner surface 27S of the shroud ring forms a moving film which is intercepted by the slots 39 and entrained in the steam passing therethrough to the turbine condenser. The outer guide blades 13L, Fig. 3, are bounded by a frusto-conical double walled ring 15 forming a continuation of frusto-conical partitions 19 and 17 carried by the penultimate rings of guide and rotor blades respectively, which partitions together with ring 15 divide the steam flow into radially inner and outer flows. Water droplets adhering to the inner surfaces of the partition 17 are shed onto the ring 15 and pass, together with some steam, through port 57 into an annular space 55 between the two walls of ring 15 and finally to a feed water heater via duct 59. Water adhering to the inner surface of the ring 15 downstream of port 57 is intercepted by and flows through tubular passages 61 in the ring 15 to the radially outer annular flow of steam and thence to the condenser.
