Title: A power driven transmission device
IPC: F16H15/04
Filed: 1958-05-15
Abstract: 867,974. Variable-speed gear. SALOMON, F. M. M. B. May 15, 1958 [May 16, 1957], No. 15682/58. Addition to 792,762. Class 80 (2). Torque is transmitted at variable ratio between an input driven wheel 9 and an outputmounted shell 17 on a vehicle by the penetration of internal axial vanes 16 on the shell 17 into a group of small spherical or hemispherically ended elements 10 carried by the wheel 9 and maintained centrifugally in a radially outer position in which they form a spherical surface. Variation.is effected by turning the output shell 17 about an axis 24, 27 from a position, shown, in which the vanes 16 are parallel with the axis of the input wheel 9 giving one-to-one drive, to a right-angle position giving zero output, the speed ratio in intermediate settings being proportional to the cosine of the angle of the axes of the disc 9 and shell 17. The input wheel 9 is driven through a bevel meshing a bevel 5 on its shaft 6, and drive issues from the shell 17 through bevels 25, 26 and a final output shaft 27. The driven shell 17 may be tilted beyond the zero position in which case the output shaft would rotate in the reverse direction. The spherical or hemispherically ended elements 10 may have depending tails with spherical enlargements pivotally and frictionally retained in circumferential grooves in the flanged surface of the wheel 9 and pressed together axially by resilient side flanges, or the tails may comprise loops frictionally retained by circular or ovoid-sectioned peripheral threads, or the tails may be apertured to receive axial locating pins and be pressed outwards by springs. The ends of the vanes 16 may be radially tapered to-reduce shock at entry and lubricating oil may be centrifuged over them. The shell 17 may be turned to vary the ratio by a crank 23 which may be controlled manually (with or without servo assistance and/or automatically using output torque and/or input speed-responsive means e.g. a spring-opposed centrifugal governor (Fig. 9, not shown) driven from, say, the input shaft 2 (not shown) and linked by a floating lever to both a manual lever and the crank 23. In Fig. 15, a gearless drive comprises two stages each of which is similar to that shown in Fig. 2, the input shaft 60 carrying the first stage driving wheel 60a and the coaxial output shaft 61 carrying the second stage driven wheel 80. The first stage driven wheel 65 and the second stage driving wheel 77 rotate together on an intermediate shaft 63, journalled in a yoke 68 which is tilted to vary the overall speed ratio in proportion to the square of the cosine of the angle between the axes of the shaft 63 and the shafts 60, 61. The second stage blades 79 are pivoted in the rim of the driven wheel 80 and are adjusted to vary the penetration depth by an annular wedge 84 which is axially moved by a rod 91 (not shown) through a fork 89.

Title: Improvements in receiving apparatus for use in wireless telegraphy and telephony
IPC: G01S3/06
Filed: 1927-06-14
Abstract: 272,915. Telefunken Ges. f³r Drahtlose Telegraphie. June 15, 1926, [Convention date]. Directive signalling - In order to secure a sharplydefined minimum or zero reading in a direction-finding installation, two coupling coils a, r are used, one of which r lies in the plane of the directive frame-aerial and rotates therewith, whilst the other a is fixed relatively to the ship or other vehicle. The coil r transfers the received signal energy S from the frame aerial to the detecting apparatus, whilst the coil a transfers the " pick-up " energy reradiated from a source of disturbance such as an iron mast B, and received by an auxiliary compensating aerial. Preferably the coil r is housed inside the coil a on the same vertical axis. As the ship changes its bearings, the coupling between the coils a. r varies according to a sine law and thus automatically compensates for any indefiniteness of the zero reading. If necessary the coupling is controlled by a shaped cam where the disturbing factors are of a complicated nature. A further fixed coupling may be provided to eliminate the effect of any constant source of disturbance. Instead of using coupling coils a, r, the impedance of the auxiliary aerial may be automatically varied by means of a variometer geared to the rotating frame aerial.

Brettle & Co., Ltd., Chapel Street, Belper, Derbyshire. June 7, 1935, No. 16533. [Class 74 (ii)] To minimize the formation of streaks or bands in knitted stockings of real silk, and, at the same time to preserve uniformity of loop, a main thread 7D is knitted to all the courses together with one of a number of auxiliary threads 2A, 3B, 4C. The same auxiliary thread is not knitted into any two successive courses. When knitted upon a straight-bar machine, the main thread knitted into every course ensures a better selvedge than is obtained by the three-thread carrier method. The main thread 7D and an auxiliary thread may be fed simultaneously to the needles so that the threads appear promiscuously at the front of the fabric ; alternatively, either the main or an auxiliary thread carrier may be traversed first so that the main or the auxiliary thread appears consistently at the front of the fabric. In knitting a stocking blank, the welt 10 is knitted with a stouter thread such as cotton, and the main panel 12 is knitted in the above manner as far as the top of the heel splicing at 13. At the line 13, the splicing 14, 14<1> for the heel and foot bottom is begun. The splicing thread may be fed for three courses so as to miss five or six needles and so to form a line 15 of local weakness for subsequent cutting so that the blank can be run on to the needles of a heeling machine by which the heel tabs are knitted.
