Title: Improvements relating to electrically operated clocks
IPC: H02K7/118
Filed: 1932-04-16
Abstract: 394,784. Motors. RUSSELL, V. J. S., Cricklewood Works, Edgware Road, London. April 16, 1932, No. 10961. [Class 35.] Rotary machines.- A synchronous motor for electric clocks is made self-starting by the provision on the rotor of a resilient or resiliently mounted magnetic member situated in or adjacent to a space between a pair of poles. As shown, a light steel blade e is anchored to one side of the permanent magnet rotor a, and the free ends which lie adjacent spaces between rotor poles may have soft-iron tips f, in which case the blade may be nonmagnetic. The natural period of vibration of the blade is preferably correlated with the frequency of current supply to the stator so that if the motor is at rest with its poles opposite the stator poles, the blade parts will vibrate and set the rotor in rotation. To prevent rotation in the wrong direction, the rotor drives, through gearing, a cam i associated with a light lever k controlled by a spring l and adapted to engage the shoulder of the cam in the event of incorrect rotation. The spring may be in the form of a single radial blade or one extending diametrically across one side of the rotor. The multipolar stator Q comprises an annular member having intermeshed poles and carrying a single exciting coil.

Title: Improvements in or relating to tensioning arrangements for cables and the like
IPC: F16F3/04
Filed: 1928-04-14
Abstract: 314,616. Callender's Cable & Construction Co., Ltd., and Ross, J. H. S. April 14, 1928. Wire and rod strainers.-A device for maintaining a substantially constant tension in a cable, strut, &c. comprises a casing B to one end of which a cable A is secured whilst its other end is formed with a flange B<1> through which the other end C of the cable, which is formed with an enlarged head D, can freely slide. A collar E is freely slidable along the cable C and is formed with apertures E<1>, E<2>, through which pass stiff spring blades F, F<1>, which are anchored at one end to the flange B<1>. The enlarged head D is provided with recesses D<1>, D<2>, through which the spring blades also pass, the bottoms of the recesses being farther from the longitudinal axis of the cable than the apertures E, E<1>, so that the spring blades between the head and the collar are in. clined. A strong spring G is confined between the collar and one end of the casing, whilst a lighter spring is confined between the collar and the enlarged head D. The spring G forces the collar along the cable until the friction between the collar and spring blades is sufficiently great to prevent further movement of the collar, which is thus locked in what will always be a substantially constant position relatively to the enlarged head D. The spring H is therefore compressed to a substantially constant degree and the tension en the cable remains substantially constant. If the cable expands and the head D moves to the right the angle of inclination of the blades F decreases, the lock is automatically released, and the spring G pushes the collar E to follow up the movement of the cable head until the friction again locks it in substantially the same position relative to the head D. If the cable contracts the reverse action takes place. In order to prevent the, full tension on the cable from acting through the relatively weak spring H a sleeve J may be secured to the head D and may be of a length corresponding to the distance between the head and collar in the locking position, so that it abuts against the collar. In a modification the spiral spring H is replaced by leaf springs, and in a further modification using leaf springs the collar is in the form of a tube having a flange against which the spring G abuts, the spring encircling the tube which in turn encloses the head G and the leaf spring. The form shown in Fig. 7 is particularly intended for maintaining a constant compression between two strut ends N, O.

IPC: H05B6/46
Filed: 1959-04-02
Abstract: 877,014. Valve oscillating circuits. RADIO HEATERS Ltd. April 1, 1960 [April 2, 1959], No. 11258/59. Class 40(6) [Also in Groups XI and XL(b) ] A valve oscillator for high frequency dielectric heating comprises a cavity resonator 2 in which the cavity is resonated by means of a pair of series-connected condensers formed by cylindrical elements 10, 12 attached to opposite ends of the cavity 2 and a common cylindrical element 14. The element 14 is supported by means of supports 16 attached by way of shock-absorbers 17 to insulators 18. The anode 22 of the oscillator valve 20 is supported by and attched to the common element 14 and is connected to earth over an R.F. choke 48. The grid 24 of the valve is connected to one end of the cavity over D.C. blocking condensers 26, the effect of the anodegrid capacity on the circuit being balanced by means of an extra element comprising a cylindrical electrode 60 connected to the electrode 14 and surrounding the electrode 10. The grid is connected to the filament over resistors 50 and 52 the latter comprising electric lamp bulbs. The filament leads are connected to a floating filament supply over R.F. chokes 36, 42 and lead-through capacitors 38, 44, one end of the filament being coupled into the resonator over three symmetrically placed blocking condenser 30 and coupling loops 32. The filament supply may comprise a pair of transformers in cascade since the negative H.T. supply is "live". A solder link 59 is attached to the anode of the valve and melts if the valve overheats, releasing a cord 61 and causing the opening of a microswitch 63 to break the H.T. supply. A sylinder of insulating material 62 provides an air duct for removal of heat from the valve and a glass cylinder 57 prevents dirt accumulating on the top of the cavity enetering the central aperture. An output signal is applied from electrode 12 to the live dielectric heater electrode 56 via four symmetrically spaced conductors 54. The oven containing the electrode 56 is resonated at a frequency higher than that of the oscillator, and the arrangement may be inverted, the oven being underneath the cavity resonator (Figs. 4, 5 not shown). In a modification (Fig. 5, not shown) an auxiliary electrode is arranged between the live electrode and the load, the auxiliary electrode being floating and removing the necessity for a large air gap between the live electrode and the load. The invention can also be applied to resonant circuits employing lumped capacitance and inductance (Fig. 6, not shown).
