Title: Improvements in or relating to electrically resonant cavities
IPC: H01P7/06
Filed: 1946-05-31
Abstract: 613,479. Cavity resonators. PHILIPS LAMPS, Ltd. May 31, 1946, No. 16543. Convention date, March 26, 1942. [Class 40 (viii)] The effect of temperature on the frequency of a cavity resonator is reduced or compensated by preventing expansion of the walls in some regions so as to enhance the expansion in other regions where the effect on frequency is less or is reversed in sign. Thus, a copper sphere, Figs. 1, 2 (not shown), in which the electric vector is along one diameter and along lines symmetrical about it, may be constrained by a clamp made of ceramic or wood, or of the alloy known under the Registered Trade Mark " Invar," so that diametral expansion is restrained and equatorial expansion is enhanced. The sphere may be thinned at the equator to facilitate deformation. Alternatively, the sphere may be inserted when cold into an inexpansible belt for constraining it along a great circle, Fig. 3 (not shown). A cylindrical resonator with axial electric vector may be constrained by a belt about the middle, Fig. 4 (not shown); or a parallelopiped, Fig. 5, by two belts 13, 14, so that with increasing temperature an expansion takes place at 16 and a compensating or over-compensating contraction at 15. The constraint may alternatively be applied internally, for instance by a ceramic rod along a diameter of a sphere.

IPC: G09F19/18
Filed: 1963-04-26
Abstract: 1,060,713. Display devices. BARRY STAINES (SALES) Ltd. Feb. 14, 1964 [April 26, 1963], No. 16605/63. Heading G5C. [Also in Divisions F2 and G2] Selected frames from two films 1 are clamped in superposition in a gate 3 for projection (Fig. 6, not shown) on to a translucent screen to form a composite picture. Each film is wound between a pair of spools 2, 5 (Fig. 2) over a sprocket 4 (only one film is shown). Four press buttons (Fig. 5, not shown) enable each film to be moved in either direction. Depression of a button energizes a drive solenoid 25, causing a roller 27 to engage a loose belt (23) (Fig. 4, not shown) between clutch plates (11), (21) giving spool 2 a positive drive from motor (10); sufficient drive being normally transmitted by clutch (19) to tension the film. Simultaneously, index solenoid 65 is energized allowing cam 9, integral with spool 4, to turn, and gate solenoid 72 is energized lifting apart gates 35, 36 which normally clamp the two films together. If the button is pressed momentarily, one film moves on by one frame, after which projection 6 on index bar 7 engages the next indentation 8 in cam 9, and gate 3 is closed. If the button is held down the film moves until the next frame after the button is released. A strip of metal foil is attached near each end of each film, and completes a circuit which stops film movement and warns the operator when the last frame of a film is in gate 3. Pushing both buttons controlling one film would actuate neither drive solenoid 25, 26, but the two buttons may be mounted on a common centrally pivoted lever to prevent such action.
