Title: Improvements in flexible pivotal joints
IPC: B25B27/28
Filed: 1925-09-23
Abstract: 243,679. Thiry, L. Nov. 25, 1924, [Convention date]. Chain, axle, and like distance members or adjusters and radius rods.-A flexible or elastic material such as rubber is interposed as a bushing between a pivot secured to one part and a socket surrounding the pivot and secured to the other part, the bushing being free at its ends and having its radial dimensions so reduced by compression between the pivot and the socket that it adheres to both members whilst allowing for an angular movement. These results are obtained by the bushing material being considerably drawn out by the insertion of its mass between walls which are of a less distance apart than the thickness of the material in its initial state. The application to the pivotal joints of the steering members and the thrust and cardan shafts of motor vehicles is referred to. P is the socket member secured to the eye of a suspension spring, and Q is a tubular pivot connected to a pair of spring shackles. Between these members an elastic material such as rubber, originally occupying the volume AA, BB, CC, DD, is stretched in an axial direction by compression so as to occupy the volume aa, bb, cc, dd. One of the members of the joint, for example a shaft, may be permitted to make small transverse movements. The length M,M of the central tube is longer than that, N, N, of the outer tube in order that certain axial forces may be permitted. The intermediate bushing may be of the general shape of rectangular section, or frusto-conical or double frusto-conical in longitudinal section. The Specification as open to inspection under Sect. 91 (3) (a), states also that the adherence of the bushing to the joint members may be effected by means of a rubber solution, which may be vulcanized, the pivot and socket members P, Q may have longitudinal or other channels, and may have annular grooves to resist axial thrust. Two or more concentric joints may be arranged in series. This subject-matter does not appear in the Specification as accepted.

Abstract: 644,432. Recording and reproducing sound. BOSWELL, I. I., and PLANER, F. E. Sept. 2, 1947, No. 24237. [Class 40 (ii)] [Also in Group XX] Sound is recorded as series of pulses modulated either in width, spacing, or frequency, or pulse code modulated. The recording medium may be capacitative, magnetic, or photographic. As applied to capacitative recording, a microphone 10 supplies an amplifier 11 whose amplitude modulated output is converted at 12 to a pulse-modulated output and applied to condenser electrodes 13, 14, on either side of a dielectric record 15 driven by a motor 18. A pulse generator 21 controls the pulse modulator in synchronism with the motor speed. Electrostatic, or in the case of magnetic recording, magnetic '' lenses " may be used to give narrower and more sharply defined pulses. The record is played back, Fig. 3 (not shown), by passing between two electrodes controlling a signal generator which gives a pulsed output that is translated into the audio frequency amplitude variations. Marker pulses may be derived from the recording to synchronize the speed of the motor. Specification 644,426 is referred to. Reference has been directed by the Comptroller to Specification 624,638.
