Abstract: 1385790 Boots &c B F GOODRICH CO 22 Aug 1972 [23 Aug 1971] 39128/72 Heading A3B A ground contacting element for use in environments of mud or the like, e.g. a sole 10 for a boot, shoe or overshoe, includes a resilient body 12 provided with a plurality of transversely extending flexible fins 13 defining grooves 14 therebetween, the fins 13 being of uniform thickness and extending at an acute angle to the body 12, the faces of each fin 13 being parallel to each other and to adjacent faces of adjacent fins. The fins 14 are thin and even in spacing and are of such a length that they trap air between adjacent fins upon deflection in such a way that they spring back into their original shape and will clean themselves if such fins have come into contact with mud. Thus the fin structure inhibits the build up of mud on the sole 10. The fins 13 may all be rearwardly inclined as shown in Fig. 1 or the fins 13 in the sole region may be forwardly inclined and the fins in the heal region rearwardly inclined. The sole 10 may be formed integral with the article of footwear or may be secured to the bottom of the article of footwear.

The level of a fluid in a tank 15 (e.g. the level of heavy water moderator with respect to a nuclear reactor core) is measured utilizing the standing-wave pattern of microwaves in a waveguide 13 projecting through the fluid surface. A standing-wave pattern is set up in waveguide 13 and in short-circuited stub 16; an attenuator 19 is adjusted to give the same maximum amplitude to both standing-wave patterns at magic-T12. A crystal detector 20 in a stub 21 is connected to a galvanometer |22 to indicate null points arising when the standing-wave patterns, referred to the magic-T, are equal in amplitude and phase. The detector feeds also a circuit for counting the number of null points sensed. The length of stub 16 may be varied manually or automatically by a micrometer 18 to permit measurement within the half-wavelengths corresponding to the null points.

As shown, Fig. 2, a domestic water heater has a base-plate 10 with a channel 12 in which runs a guide 15 on the base of the ashpan 14. A coil spring 32, housed in a recess 30 centrally disposed in the channel 12, forces a ball 33 against a coverplate 31, apertured to allow part of the ball 33 to protrude through the plate. When the ashpan is in position, the guide 15 bears on the ball 33 slightly compressing the spring 32, and a ring 14a riveted to the upper edge of the ashpan 14 at 14b is forced against circular member 20 supporting the firegrate 21, firebox 22 and boiler 24. In an alternative embodiment, Fig. 4, in which the ashpan serves to regulate air intake, the member 20 has on its underside an arcuate cam track 35 non-concentric with the centre of the ashpan. A pin 36 carried by the ring 14a enters the cam track when the ashpan has been partly pushed home, an air inlet 37 being left between the ashpan and the member 20. A part-rotary movement of the ashpan gradually closes the inlet 37.

[Class 81 (ii).] An apparatus for testing the acuity of hearing comprises a vibratory sound-producing medium, an impact member releasably held at a predetermined height and adapted to strike said medium, and sound-insulating means removably interposed between said medium and the ear of a, listener. As shown, the impact member consists of a pendulum 10 provided with a rubber-tipped hammer 13, and is releasably held at a predetermined height by spring-pressed lever 14. Each of a series of tuning forks 17-22 of different pitches is mounted in a rubber collar 29 in uprights 23-28, each upright being pivoted at the base and yieldably supported by pads 33. 34. The series of forks is mounted on a base 36 operatively connected through bolt 37 to handle 38, so that a turning of the latter will bring any of the forks into a position to receive the impact of the falling hammer. One fork may be used in place of the six shown. An apertured ear-rest 39 is disposed opposite the point of impact of the hammer, the aperture being normally closed by a pivoted shutter 42. In operation, the ear of the patient is placed at the ear rest, the shutter being open, and one of the forks is actuated. When the sound is no longer heard, the shutter is closed so that the ear may be rested. The shutter is then opened again, and this procedure is continued until the sound is no longer heard when the shutter is reopened. The periods of audibility in respect of each of the forks are compared with the corresponding periods obtained for a person of normal hearing. The stop watch employed may be mounted on the bracket on which the lever 14 is pivoted, a projection on this lever actuating the release on the watch.
