Filed: 1924-06-26
Abstract: 231,813. Smithe Machine Co., Inc., F. L., (Assignees of Novick, A.). April 4, 1924, [Convention date]. Envelopes, making.-A folding member for envelope blanks is mounted in a slide-member so as to be movable in two directions, substantially at right-angles to and in the plane of the blank respectively, the movements being separately effected. The invention is shown in connection with the folding of the side flaps of a bag-shaped envelope, and each folding member comprises. two blades 91, 92, which move upwardly together to raise the side flaps, and then move inwardly as shown in Figs. 7 and 8, the blade 92 overtakitg the blade 91 to press the central seam. A finger 93 retards one flap so that it is placed over the other flap, which has been gummed. The side flaps are raised prior to the operation of the blades 91, 92 by lifters 90. The blanks are fed by a belt 15 beneath forming blades 12, 13, which are placed above guides 18, 19, and are centred and aligned against stops 65 on a bar which carries the bottom flap folding plate 68. The folded envelope is delivered between rollers 86, 87 by the movement of the blades 12, 13. The folding blade 91 is carried by a member 100 sliding in a T-shaped frame 105 bolted to the machine frame 8. Links 142 operated by endcams give the member 100 a longitudinal movement, while a blade 114 sliding in the frame 105 and engaging a slot 120 in the member, gives it a short, slow, transverse movement to raise the side flap. A cam 130 and a lever 125 effect this movement. The folding blade 92 is pivoted at its rear end to a lever 151, the other end of which is mounted on a pin 153 on the blade 114, passing through the frame 105. A link 156 connects the member 100 with the lever 151, thus increasing the longitudinal movement of the blade 92. A spring 159 urges the blade 92 towards the blade 91. The side flap lifters 90 are mounted on rods 170 sliding in guides 172 and operated from a cam 184 through levers and links. The retarding finger 93 is adjustably mounted on a pin 195 carried on a bracket 196 secured to the machine frame.

Title: Improvements in high frequency antenna system
IPC: H01Q9/26
Filed: 1942-11-16
Abstract: 561,251. Wireless antennae systems. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 16, 1942, No. 16196. Convention date, Nov. 15, 1941. [Class 40 (v)] A short -wave antennae system, which when used for transmission gives horizontally polarized radiation substantially uniformly distributed in a horizontal plane and concentrated at low angles in the vertical plane, comprises two or more closely spaced separate conductors 20, 21 forming a loop with a narrow gap, the corresponding ends of the conductors being connected together and terminating in means providing substantial capacity across the gap. One conductor 21 is coupled to the transmission line 24, and the system has an effective electrical length equal to half that at-the operating frequency. In the form shown, capacity plates 26, 27 in the form of shoes are attached by screws passing through slots to blocks welded to the ends of the conductors so that they may be adjusted towards and from one another to tune the system. The conductor 21 is opened at its centre to provide terminal connections to the transmission line, the feeding point impedance being variable within limits, without seriously affecting the frequency of the system, by .a variable capacity formed by two discs (not shown) carried by spindles screwed into the ends of the conductor at this position. The system is supported from a pole 28 by a member 29 connected to the midpoint of the conductor 20, which is a voltage node, so that the member 29 and pole 28 may be of metal tubing without affecting the operation of the system. The system serves as an impedance matching transformer, the feeding point impedance of a number of sections of equal diameter being approximately that of one section multiplied by the square of the number. The ratio may be varied within limits by the use of conductors of unequal cross-sectional diameters, as in the form illustrated. An antennae arrangement giving greater vertical directivity and greater gain in the horizontal plane, shown in Fig. 8, comprises a number of the antenna systems described arranged in vertical alignment and spaced apart by substantially one wave-length. The units may be energized in phase by common concentric transmission lines 64, 65 providing a balanced feed, the impedance presented to the transmission line by each unit being raised by means of quarter-wave matching sections 66- 69. For high powers, a separate transmission line is preferably used for each unit. The loop may be of other form than circular, for example, of square or other polygonal shape, and the conductors forming it, instead of being superposed, may be of slightly different sizes and arranged in one plane to form parallel curves.

Abstract: 1,268,225. Piezo-electric elements. THOMSON-CSF. 27 March, 1969 [3 April, 1968], No. 16233/69. Heading HIE. The thickness of a rectangular DT-cut quartz crystal plate is chosen to eliminate certain undesired modes of vibration. The fundamental resonance of such a plate is associated with a face shear vibratory mode, but undesired bending vibrations dependent upon the thickness of the plate may occur. For a plate of length L, width W and thickness E, the ratio A=W/L is chosen to obtain a high Q in a particular frequency range. Using the graph, a value of R=E/L (and hence a value of E) may be found which eliminates the unwanted bending modes. On the graph, the ordinates represent C=fL, where f is the resonant frequency in MHz and L is expressed in mm. The segments 2, 3, 4, 5, 11, 12 correspond to principle-mode resonances for A= 0.175 and A= 0À4, and the segments 6, 7, 8, 9, 13, 14 represent undesired modes. The angle of cut of the plate may be chosen to obtain zero frequency/temperature coefficient. Reference has been directed by the Comptroller to Specification 1,116,699.
