Abstract: 1,013,351. Air turbines. WESTWIND DEVELOPMENTS Ltd. Sept. 15, 1964 [Oct. 24, 1963], No. 42004/63. Heading FIT. An air turbine comprises a rotor having a shaft portion with a disc at one end of larger diameter than the shaft, means for maintaining an air bearing film between the shaft and at least one bearing surface extending circumferentially around the shaft and between the rotor disc and end thrust bearing surfaces facing the two sides of the disc, and bores in the disc that terminate in outlet jets from which air escapes to provide a reaction drive to the rotor. An air turbine comprises a housing 1 containing a cylindrical bearing sleeve 2 surrounding a rotor shaft 4. An enlarged end disc portion 5 of the rotor has an axial port 7 receiving compressed air from an inlet port 10 in the housing end cover 9. Some of the air flows radially outwardly through bores 6 in disc 5 to issue through jets 8 adjacent pockets in the rotor, Fig 2, and thus effect rotation of the rotor. This air exhausts through ports 19 in housing 1. The remaining air flows through passages 16, 11 from inlet 10 to annular recesses 12a, 12b in housing 1 and thence to recesses 13a, 13b in sleeve 2. This air then flows through holes 14a-14d in sleeve 2 to form an air bearing supporting the rotor or through holes 21 in sleeve flange 3 to space 20 to form a thrust bearing. A thrust bearing is also formed by air between disc 5 and end cover 9. The bearing air exhausts through ports 18, 18a and 19. The rotor drives a grinding wheel 23 or may be formed to accept a grinding wheel collet.

Title: Scissor action hoist with components shaped so as to lie alongside one another
Inventor: LODIGE ALOIS
IPC: B66F7/08
Filed: 1967-09-22
Abstract: 1,203,951. Scissor hoists. A. LODIGE. 22 Sept., 1967 [26 Sept., 1966], No. 43283/67. Heading B8H.  In an hydraulically operated scissor hoist with two pairs of arms 3, 4 pivotally interconnected at the centre thereof, the ends of each pair of arms are connected by beams 18, 24, 26, 28 to form closed frameworks and mount brackets 9, 20, 25, 31 whereby one end of the arms are respectively pivotally attached to a base 1 and a platform 2 and the other end of the arms mount rollers 10, 32 for movement in guideways 8, 15 attached to said base 1 and platform 2. The brackets 9, 20, 25, 21 are shaped and mounted as to allow the arms 3, 4 to lie substantially in the same plane when the hoist is in the retracted position, the overall height of the hoist in their position is substantially equal to the height of the base plus that of the platform. An hydraulic actuator 5 is pivotally mounted between one end of the arms 3 and a lever 21 affixed to a beam 22 interconnecting the centres of the arms 4. In an alternative embodiment, Fig. 7 (not shown), a pair of hydraulic actuators act in opposite direction upon the beam 22 with half the leverage. In a further embodiment, Fig. 10 (not shown), the arms are of unequal length with respect to the pivotal axis 19 whereby the negative angle obtained thereby between the arms in their retracted position effectively increases the lifting distance of the hoist. The end of the platform prescribes an arc (35). In a further embodiment, Fig. 11 (not shown), those ends of the arms which are not raised are mounted on wheeled trollies (37) and (38), (39). In a development thereof, Fig. 12 (not shown), a series of pivoted levers (42), (43) are engaged by the platform on lowering thereof whereby to lower the wheels into contact with the ground. Means are provided to lock said wheels in their extended position. In Fig. 15 (not shown), tie bars (61), (62), (63) are provided between the ends and the pivotal axis (19) of the arms on which the hydraulic actuators are mounted to alleviate the strain produced thereby. The action of the actuators may be transmitted to the beam (22) by a double rack (64) and pinion, Fig. 16 (not shown), or alternatively a flexible chain or cable (70) may be attached to bearing members (68) on said beam, Fig. 18 (not shown).

Title: Thermostatically controlled clutch mechanism
Inventor: SETTIMI RAYMOND J
IPC: F16D43/25
Filed: 1961-12-04
Abstract: 1,000,420. Friction clutches. BORGWARNER CORPORATION. Dec. 4, 1961, No. 43357/61. Heading F2C. A clutch for connecting the shaft 26 of a water impeller to a motor vehicle engine cooling fan 14 comprises a driving drum 34 fast with the impeller shaft and a radially expansible friction clutch band 16 mounted upon a driven hub 12 to which the fan is secured, a bimetallic clutch coil 18 connected between the hub and the clutch coil expanding with increasing temperature to engage the band with the drum. One end 60 of the clutch band 16 extends into a radial slot 61 in the clutch hub 12, while the other end 62 is provided with an axially extending projection 63 formed with an axial slot 64. The inner end of the bimetallic strip 18 is secured to a hub cap 68 fast with the fan 14, while a radially projecting tab 78 at the outer end of the bimetallic strip engages in the slot 64 in the axial projection 63. The fan 14 draws air through the radiator 88 of the engine driving the motor vehicle. On starting, the bimetallic strip 18 holds the clutch band 16 radially inwards of the drum 34, so that the fan 82 is rotated with the impeller shaft 26 only by friction within its mounting bearings 50. With increasing temperature, the bimetallic strip 18 expands the clutch band 16 into initial light engagement with the clutch drum 34. As the fan 14 is rotated with a progressively increasing speed, centrifugal force acts upon the clutch band 16 to engage it more firmly with the clutch drum 34, and a mechanical self-servo action caused by the mechanical drive tending to unwind the band increases the engaging force, until the fan rotates at the same speed as the impeller shaft 26. When the bimetallic strip 18 cools down, the band is rapidly restored to its contracted disengaged position, initial partial disengagement reducing the centrifugal force acting upon the band and thus assisting rapid completion of engagement. As shown, the clutch band 16 consists of a single coil, but in a modification, Fig. 4 (not shown), is formed by a double coil. Specification 1,000,419 is referred to.

Title: Semi-automatic spark gap setter
IPC: H01J17/00
Filed: 1963-11-04
Abstract: 1,059,585. Spark gaps. RITTER CORPORATION. Nov. 4, 1963 [Nov. 14. 1962], No. 43504/63. Heading HIX. A spark gap setting mechanism comprises a pair of electrodes 10, 11 arranged to engage each other in a closed position, means (pin 12) for separating electrodes 10, 11 to define a spark gap therebetween, a tapering member 14 coupled to the separation means, means for moving member 14 into a reference position relative to the separation means when the electrodes 10, 11 are in contact dependent on the wear of electrodes 10, 11, and means for pivoting member 14 through a predetermined arc to separate electrodes 10, 11 a predetermined distance. The object is to maintain the same gap despite wear of the electrodes. Electrode 10 is carried by rigid plate 18 joined by a pair of insulated nuts and bolts 23, 21 to resilient plate 20 carrying electrode 11 and pin 12. The resilience of plate 20 maintains electrodes 10, 11 in a closed position. Member 14 terminates in a body 26 which is carried in a support 16, member 14 being biased towards the left by tension spring 28. Support 16 is mounted on a bracket 42 secured to plate 18, the support 16 being pressed upwards by springs 36, 38 against the end 46 of bracket 42 and against a stop formed by adjustable stud 40. A handle 34 in body 26 projects through a slot 32 in support 16 and is engaged by a rod 56 on push-button 57 supported resiliently by a rod 78 fastened to wall 74 of a housing by bracket 79. Push-button 57 is biased towards the left by compression spring 80. In operation, push-button 57 is moved to the right manually, which forces member 14 from pin 12 allowing electrodes 10, 11 to come into contact, then released. Member 14 returns to the left until it comes against pin 12, where it remains without sufficient force to depress pin 12. Button 57, now on the left, is depressed manually, which causes support 16 to pivot about point 58 on the end of stud 40 until the left-hand end of support 16 comes against an adjustable stop 62, thus causing the support to tilt which allows member 14 to be retracted further under the action of spring 28 until it again comes up against pin 12. Button 57 is then released which allows the left-hand end of support 16 to be pivoted upwards by spring 38 which causes member 14 to pivot down depressing pin 12 and separating electrodes 10, 11 to form a gap which is constant regardless of the wear of electrodes 10, 11.
