Title: Constant velocity universal joint
IPC: F16D3/223
Filed: 1966-02-11
Abstract: 1,105,579. Universal joints. LOHR & BROMKAMP G.m.b.H. 11 Feb., 1966 [10 June, 1965], No. 6125/66. Heading F2U. Relates to a non-telescoping constant velocity ratio universal joint having torque transmitting balls 7 in grooves 11, 10 respectively in inner and outer joint members 1, 8, and in which the grooves are either straight and crossing one another in Cooperating pairs with alternate opposite inclinations (Figs. 2-4, not shown) or, as shown, arcuate and diverging in depth in Cooperating pairs alternately to opposite hands. In such a joint, the balls are positioned in the bisector " constant-velocity plane" by the co-operation of corresponding grooves, and retained in this plane by a spherical cage 16 which is disposed between the joint members, slides on the inner (Figs. 2-4, not shown) or, as shown the outer joint member without freedom perpendicular to the cage axis in relation to that joint member, and has clearance 18 with respect to the outer or, as shown, the inner joint member. In the joint shown, the angle of divergence of the co-operating grooves between groove pairs is only slightly greater than the angle of friction between the material of the balls and the material of the joint members. In Figs. 2-4 (not shown), the angle at which co-operating grooves cross is substantially equal to the maximum bending angle of the joint. The ball apertures in the cage are elongated circumferentially thereof to allow ball movement on bending of the joint. The outer element (28) is secured to its shaft by bolts (44) which also secure a protective end cap (48). In assembly, the inner joint member together with the cage and balls is pivoted into the outer joint member about two of the balls.

Title: Granular bed filter
IPC: B01D24/08
Filed: 1962-02-20
Abstract: 957,002. Filters for liquids. M. J. MARTIN. Feb. 20, 1962, No. 6451/62. Heading B1D. Water, e.g. from a swimming pool (not shown), flows at 16 into a covered chamber 10, Fig. 3, and passes inwards through a bed of sand or the like 48, Fig. 6, enclosed within a drum 30 covered with wire gauze. Filtered water is withdrawn by a pump 54 through a valve 38 and discharged through the same valve at 52 for return to the swimming pool. The water level 20, Fig. 3, is the same as that in the swimming pool. For cleaning, inlet valve 18 is closed and a waste pipe valve 26 is opened, the water level dropping to 20a, Fig. 3. Valve 38 is turned to permit water from the pool to be pumped back through the pipe 40. With the drum at rest this wash water channels upward through the sand, but the drum is mounted to be rotatable (e.g. by hand), and as it is rotated clockwise, Fig. 6, all the sand is progressively washed. A restrictor valve 37, Fig. 3, fully open during filtration, partially closes during backflushing. In Fig. 9 a separate fixed perforate pipe 62 is provided to conduct away the backflush water to a separate pipe 68, to prevent it mixing with the unfiltered water in the chamber 10. This segregation is assisted by an arcuate hood 70 arranged over the upper portion of the drum. In all cases the filter may be operated under pressure instead of suction. In another alternative, means responsive to the pressure drop across the bed may actuate switches to cause operation of the appropriate valves and to cause a motor to turn the drum through one or more revolutions, for backflushing.

Title: Improvements relating to seats
Inventor: TAYLOR NORMAN
IPC: A47C3/28
Filed: 1962-02-20
Abstract: 988,598. Seats. ROC INSTRUMENT CO. Ltd. Feb. 20, 1962, No. 6452/62. Addition to 912,205. Heading A4J. The locking member ring 21 of the vertically adjustable seat of the parent Specification is releasable from frictional locking engagement with the depending member 11 by release means which cannot be operated when a person is sitting on the seat pad. The locking member 21 rests on two posts 19 and can pivot about the axis 20 afforded by these posts. The release means comprise a lever 24 having a handle 25 and an operating part 27 which rests on the locking member 21. Holes are formed in the part 27 and member 21 for a spring mounting post 22. A helical compression spring 30 on the post bears on the upper side of the part 27 and a lighter compression spring 31 on the post bears against an underface of the locking member 21. When a person sits on the seat pad the member 21 pivots about the axis 20 so that it exerts a frictional clamping action on the member 11 sufficient to bear the weight of the person. The spring 30 urges the operating part 27 to pivot about the axis 20 to bear against the upper face of the member 21. If the handle 25 is swung downwardly about the axis 20 the operating part 27 will move away from the member 21 without affecting it. If the handle 25 is lifted the part 27 will pivot about a part of the post 22. When the person rises from the seat pad a spring 16 exerts a pressure on the locking member 21 to retain it in its locking position. Downward movement of the handle 25 will cause the operating part 27 of the lever to pivot about the axis 20 and to compress the spring 30 into a solid position. A heel piece 32 on the part 27 will bear on a tongue 33 of the locking member 21 to cause it to approach a horizontal position in which it releases the depending member 11.

Filed: 1952-03-14
Abstract: 705,783. Magnetron amplifiers; space charge wave tubes. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. March 14, 1952 [March 29, 1951], No. 6728/52. Class 39(1) In a travelling wave magnetron the spacing of the two electrodes between which the transverse electric field is set up increases along the discharge space in the direction of travel of the beam, and means are provided for maintaining the transverse electric field constant along the length of the discharge space. This is achieved by forming the relatively negative electrode of resistive material the thickness of which may be variable, Figs. 2, 4 (not shown), and passing a current along it, or by splitting it up into a number of sections 3, Fig. 3, connected to spaced tapping points on a potentiometer 9. The envelope of the beam, initially of ribbon form, widens as shown by the dotted lines due, it is stated, to exchange of energy between electrons; the shape of the delay line and increasing negative potential of the relatively negative electrode ensure that as few electrons as possible impinge on these parts. The expression travelling wave magnetron ' is defined to include (a) travelling wave magnetron amplifiers, (b) the travelling wave magnetron oscillator described in Specification 699,893, (c) the space charge wave amplifier with crossed fields described in Specification 692,705. In the form shown, the delay line 2 is supported by rod 10 from flexible tube 11 so that it can be variably inclined.

Abstract: 816,022. Testing pressure gauges. BRYANS AEROQUIPMENT Ltd., and AUSTIN, J. Feb. 28, 1957, No. 6795/57. Class 106 (2). An apparatus for testing "rate of climb" indicators comprises two similar manometers, comprising cisterns 20 containing mercury vented to atmosphere and vertically adjustable against scales 40 graduated in units of altitude, fixed sighting tubes 28, 30, flexible. U - tubes 24 connecting the lower ends of the sighting tubes 28, 30 to the cisterns 20 and single downwardly - extending probes 56, 58 in the tubes 28, 30 respectively ; the lower ends of the two probes 56, 58 being at the same fixed level. The apparatus also includes a clock 76, which is started when the mercury in the left-hand manometer touches its associated probe 58 and stops either when the mercury in both manometers is touching the associated probes or when no such contact is made. In operation, the scales 40 are adjusted vertically by means of screw jacks 48, to allow for the ambient atmospheric pressure, so that the test is conducted at a standard pressure. The cisterns 20 are then each lowered until marks 44 on them are level with the graduations on the scales 40 corresponding to the heights between which the test is to be conducted; the left-hand cistern corresponding to the lower height and the right-hand cistern corresponding to the upper height. Suction is now applied to the pressure chamber containing the " rate of climb " indicator being tested until it reads steadily at the required rate of climb. A union 74, connected by tubing 66 to the tubes 28, 30, is now connected to the chamber and when the mercury in the left-hand tube 30 makes contact with its associated probe 58, the clock 76 starts. The clock stops when the mercury in the right-hand tube 28 rises above its associated probe 56. From the elapsed time, the error in the instrument reading can be calculated. The device may similarly be used for testing the indicator when a descent is being simulated.

Abstract: 1,195,466. Leno or fancy weaving apparatus. N. HODGKINSON. 13 Feb., 1969 [13 Feb., 1968], No. 7013/68. Heading D1E. Warp yarn packages 10, 11 are mounted on a rotating platform 12 and are themselves rotated oppositely, by sun and planet gears, so that the yarns coming from the packages have no change in their amount of twist, the yarns then pass through guide eyes which twist the yarns together, through a tensioner 8 and a device 6 which compensates for changes in tension during shedding, the yarns then separate and pass through eyes 14 in a disc 5 that rotates at the same speed and in the same direction as the platform 12 and then pass through a leno shedding motion that results in either a half cross or a full cross weave. The leno shedding motion comprises rods that are oppositely shed by a cam-link and pulley arrangement, one rod having an upwardly directed hook 14 and the other a downwardly directed hook 13. If the disc 5 rotates at half loom speed each thread will engage alternate hooks to produce a leno weave with a half cross between the picks and if the disc 5 rotates at loom speed each thread will always engage the same hook to produce a leno weave with a full cross between each pick. The leno weaves may be at any position in the fabric and a loom is described which produces leno edge and centre selvedges.
