Title: Flushing toilet
IPC: E03D5/016
Filed: 1949-12-13
Abstract: 672,306. Pump-discharged closets. AIR SERVICE TRAINING, Ltd., and BENNETT, R. H. M. Nov. 15,1950 [Dec. 13,1949], No. 31930/49. Class 26 [Also in Group XXVI] A pump-operated toilet has a pump of the rockable vane type, the shaft of which carries a pinion associated with oppositely disposed coaxial elements, each carrying angularly spaced sets of teeth which are respectively axially staggered, and arran-- ged so that, as the actuating shaft rotates, the tooth sets of the two elements alternately engage the pinion thus rocking the vane. Shown applied to the self-contained type of toilet, in which the digestant liquid is recirculated through the wire mesh 20 via the pump 17 and the outlet pipe 43 to the pan 15, the control pedal 19 is loosely mounted on the actuating shaft 21 and carries a pawl which coacts with an eighttoothed ratchet wheel fast on the shaft so that a depression of the pedal, which is spring returned, rotates the shaft through one-eighth of a revolution. The shaft 21 also carries a pair of discs 23, Fig. 2, each of which has four spaced sets of teeth 35, Fig. 4, the teeth sets on one disc being axially staggered with respect to those on the other. A pinion 36 is mounted between the discs and is connected via the shaft 42 to the rockable vane 41 which moves within a casing 17, semi-circular as plan, Fig.3, Depressions of the pedal cause the tooth sets of alternate plates to engage the pinion 36 and so oscillate the vane 41 through just less than 180 degrees and the liquid is drawn through the valved ports 40 and forced out through the outlet pipes 43. Specification 638,804 is referred to.

Title: Fluid-pressure relays
IPC: F16K31/126
Filed: 1949-12-13
Abstract: 685,928. Fluid-pressure servomotor-control systems; valves. PUTMAN, R. E. J., SCHIPPERS, J. F., and GORDON & CO., Ltd., J. July 28, 1950 [Dec. 13, 1949], No. 32016/49. Class 135. In a fluid-pressure relay, a force dependent on a pressure difference is applied to a pivoted beam which actuates a control valve, and a force proportional to the control pressure so produced can be applied to the beam in the same or opposite sense as the first-mentioned force to increase or decrease the effect of the latter on the control valve. In an embodiment, separate pressures are led into chambers 4a, 4b, Fig. 2, on opposite sides of a diaphragm 5, and the force due to the differential of the two acts through a composite stem 14 on to a beam 21 which is fulcrummed at 22 and is loaded by a spring 27. Packing bellows 8, 9 around the stem 14 prevent leakage of fluid from the chambers 4a, 4b. The diaphragm is loaded by an adjustable spring located at 16 or 16a according to whether the movement of the diaphragm is to produce a rising or falling control pressure with rising differential pressure. Movement of the beam 21 actuates a valve 28 to produce a control pressure in a chamber 35, this control pressure being available at an outlet 36. The control pressure is also applied through a conduit 38 to a chamber containing a bellows 30, the latter acting on a lever 31 which, in its turn, acts through an abutment 39 on to the lever 21. The position of abutment 39 is adjustable to one side or the other of the fulcrum 22 so that it will act on the lever 21 to increase or decrease at will the effect of the differential pressure on the control pressure. Valve 28 comprises the chamber 35, Fig. 3, with a valve 33 controlling the inlet of air at constant pressure through the port 32 and a diaphragm-supported valve 34 abutting the lower end of the stem of valve 33 and constituting an exhaust valve for the chamber. Valve 34 carries a tappet 37 in contact with lever 21. An upward movement of lever 21 opens inlet valve 33, and a downward movement of valve 34 vents chamber 35. The conduits leading to chambers 4a, 4b pass through a rotary-cylindrical shut-off valve 6, and the chambers can also be interconnected by a by-pass valve (not shown). The stems of these last two valves carry discs 52, each of which is formed with a cut-out portion 53 to interlock the two valves. To bring the relay into operation, the by-pass valve must first be opened before the shut-off valve can be opened and, after this has been done, the by-pass is closed to separate chambers 4a, 46.

Abstract: 1495374 Toy vehicle flywheel drives MATSUCHIRO KK 2 Aug 1976 [1 Aug 1975] 32159/76 Heading A6S A toy vehicle is powered by a flywheel 11 connected to a ground-engaging wheel 3 through a forward-reverse gear train with a gear-selection lever 12 having four gear-select positions corresponding to (a) forward drive of the flywheel 11 on forward drive of the wheel 3 permanently established; (b) forward drive of the flywheel 11 on forward drive of the wheel 3 with automatic gear establishment and disestablishment on rotation, &c of the wheel; (c) reverse drive of the flywheel 11 on forward drive of the wheel 3 with automatic gear establishment and disestablishment on rotation, &c of the wheel; and (d) reverse drive of the flywheel 11 on forward drive of the wheel 3 permanently established. The wheel 3 is fast with a shaft 3a and a gear 5 always meshing the smaller gear 6a of an idle gear pair 6a, 6b fast on a shaft 6. Slots 4a on opposite sides of a gear frame 4 journal the shaft 6, opposite ends of which lie between abutments 13b', 13b" in hooks 13b of a gear selector 13 fast with the gearselection lever 12. The gear selector 13 pivots about the wheel shaft 3a and has spring biassed detents 13a' engaged in one or other of four pairs of detent holes 4c ... 4f, corresponding to the four gear-select positions (a) ... (d). The idler gear 6b can mesh either with a pinion 8a, to drive the flywheel 11, or with a pinion 7a to drive through a pinion 7b meshing a gear 8b fast with the pinion 8a. The gear 8b drives through the permanently meshed gears shown to the flywheel 11. When the gear selector 13 is in one of its two intermediate positions, e.g. as in Fig. 3, the ends of the shaft 6 can slide along the frame slots 4a between the abutment surfaces 13b', 13b" in the frame hooks 13b. On rotation of the wheel 3 in the appropriate direction, the idler shaft 6 will then be slidden along the slots 4a to its meshed position with the pinion 7a or the pinion 8a, to drive the flywheel 11. If the toy vehicle strikes an obstruction, the idler shaft 6 will slide in the opposite direction along the slots 4a, and automatically disengage drive from the flywheel 11 to the wheel 3.

Title: Annular face shaft seals
Inventor: GARDNER JOHN MADDOX
IPC: F16J15/34
Filed: 1957-10-15
Abstract: 830,059. Stuffing-box substitutes. NAPIER & SON Ltd., D. Oct. 15, 1958 [Oct. 15, 1957], No. 32261/57. Class 122 (5). The shaft 10 of a rotary pump intended to pump radio-active carbon dioxide is sealed where it passes through the pump casing 11 by means comprising a ring 14 carried by the casing and having an end face 15 that opposes a corresponding face 21 of a ring 22 carried by the shaft, and has two spaced annular channels 16, 17, therein, the inner channel 16 communicating with a source of compressed-air at a pressure greater than that of the gas in the pump casing space 29, which air flows from the channel 16 to maintain a clearance between the faces 15 and 21, and the outer channel 17 being maintained at a pressure below that in the space 29 to receive air flowing outwardly from the channel 16 and also any gas leaking from the space 29. The carbon ring 14 is fixed to a backing member 13 secured to the casing 11 and the steel ring 22 is secured to a ring 26 connected by outer and inner bellows 24 and 25 to a mounting ring 23 fixed to a flange 20 on the shaft. The channels 16 and 17 communicate respectively with a compressed air supply passage 18 and a drain passage 19. The space 28 between the bellows 24, 25 is corrected by a passage 27 with the drain channel 17. In operation, compressed-air admitted to the channel 16 separates the faces 15 and 21 by a small clearance through which air escapes radially inwardly to the atmosphere through aperture 12 and radially outwardly to the drain channel 17 which also collects any carbon dioxide leaking inwardly through the clearance. In modifications, the carbon ring is axially movably mounted by being connected to the pump casing either by inner and outer bellows or by a piston and cylinder type mounting and co-operates with an axially fixed ring secured to the shaft, compressed-air being supplied to the end face of the carbon ring through a flexible pipe that may enter through the space between the bellows.

Patent GB-664257-A (GB)
Title: Electrical switch and variable resistor for miniature electrical apparatus
IPC: H01C10/36
Filed: 1948-12-14
Abstract: 664,257. Electric switches. DEHN, S. G. (Globe-Union, Inc.). Dec. 14, 1948. No. 32346/48. Class 38 (v). [Also in Group XL (c)] An electrical switch and variable resistor assembly comprises an operating shaft rotatably mounted in a base, a variable resistor mounted on one side of the base, a switch mounted on the other side of the base within the periphery thereof, the switch including a switch blade pivotally mounted directly to the said other side, a cam carried by the shaft and directly reacting with the blade in one position of the shaft to operate the blade, and a knob mounted on a shaft rotatable with respect to said base to regulate said variable resistor and operate said switch. A base-plate 10 of insulating material has a variable resistor 8 mounted on one side within the control knob 11. On the other side of the base 10 are mounted the resistor terminals 12, and two switch terminals 18, 19, these latter being mounted on fixed contact plates 14, 15 respectively. The hexagonal bases of the threaded terminals 18, 19 are held against rotation by lugs 23 so that nuts can be screwed on to the terminals. The contact plates 14, 15 are located against a semi-circular raised portion 16 of the base and fixed with rivets 17. On the plate 15 a movable contact blade 26 is pivoted at 20. An insulated cam 34 is loosely mounted on the rectangular end of the control shaft 13 and a cam follower 32 on the movable blade 26 normally rests in a notch 36 between the two cam teeth 37, 38 being retained therein by a spring 30 which also serves to keep the movable blade 26 in contact with the fixed plate 15. When the control shaft 13 is turned clockwise by the knob 11 the lost motion due to the loose fit of the cam 34 on the shaft 13 is first taken up and then the follower 32 rides up the inner arcuate face of the cam tooth 37, being forced with a snap action down the other side of the tooth by the spring 30 to bring contacts 26 and 14 together with a rubbing, self-cleaning action. For the remainder of the rotation of the resistor shaft 13 and its cam 34 the contacts 26, 14 are undisturbed since the follower 32 is held clear of the cam 34 by the engagement of the heel 33 of the movable contact 26 with a lug 24 on the fixed plate 15. When the resistor shaft 13 is returned to its normal off position the follower 32 rides up the face of tooth 37 to open the switch contacts 14, 26 and drops into the notch 36, the contacts remaining open. If it is desired to rotate the resistor control shaft in the opposite direction, the operation is similar but cam tooth 38 is brought into play instead of tooth 37. The fixed contact plates 14 and 15 may if desired be extended as at 21, 22 to form mounting lugs.

Title: Improvements in and relating to electric eddy current brakes
IPC: B60L7/00
Filed: 1936-11-26
Abstract: 487,865. Eddy-current brakes. MANDL, A., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Nov. 26, 1936, No. 32429. [Class 103 (i)] In an eddy-current brake the member or rotor which co-operates with the magnetic pole system comprises a low resistance closed circuit conductor system or element disposed in an element of magnetic material whereby at lower speeds the low resistance element links with the flux to produce substantial eddy currents therein while at higher speeds the flux is confined to an outer zone of the member so that substantial eddy currents are produced only in the high resistance magnetic material, the braking effort being thus maintained of the same order of magnitude throughout the major portion of the speed range of the brake. As shown in Fig. 1, stationary yoke members 4, 5, have a series of polepieces 9, 10 between which is the rotor secured to the shaft 1 and which comprises an annulus 13 of iron and spokes 14. The low resistance element comprises a simple annulus 16 of copper or inner and outer rings connected by spaced radial parts. At high speeds the flux is confined to an outer zone of the annulus 13 as indicated by the lines a so that the element 16 is ineffective, but at lower speeds the flux passes through both the magnetic material and the element 16 as indicated, for example, by the lines c so that substantial eddy currents are produced in this element, and a corresponding braking torque. The winding circuit of the pole system is preferably such that, as indicated in Fig. 5, adjacent poles are of opposite polarity, at high speeds, to produce eddy currents of high frequency, but at low speeds the windings are reconnected so as to produce groups of adjacent poles of the same polarity whereby the stray flux between adjacent poles and which does not traverse the element 16 is reduced. Thus a reversing switch 29 may be provided which in the full-line position produces the arrangement shown, while in the broken-line position the three upper poles are of south and the three lower poles of north polarity.
