Title: Improvement in Wireless Radio SIgnalling by the Arc-system.
Inventor: COHEN LOUIS
IPC: H03B11/08
Filed: 1917-03-01
Abstract: 113,498. Cohen, L. March 1, 1917. Wircless signalling.-In the are system of wireless telegraphy, signalling is effected by increasing the resistance in an auxiliary oscillatory circuit in parallel to the aerial circuit, the time-constants of the two circuits being such that during the intervals between signals, the current passing in the aerial is practically zero. As shown in Fig. 1, the supply generator g is connected through choking- coils to the arc 3, which is also included in the aerial circuit comprising antenna 1, inductance 2, arc 3, and earth 4. The auxiliary oscillatory circuit comprises earth 4, arc 3, inductance 2<a>, capacity 5<a>, variable electrolytic resistance 7, and earth 4<b>. The electrodes 6, 6<a> are in contact during the intervals between signals, and the low time-constant of the auxiliary circuit diverts the current from the aerial under these conditions. The action of the transmitting-key is to separate the electrodes 6, 6a thereby greatly increasing the resistance of the auxiliary circuit, and causing current to flow in the aerial. A condenser 5 shunted across the arc serves to keep it steady whilst signalling. In a modification, the transmitting-key is placed in a short circuit across a metallic resistance in the auxiliary circuit.

Title: Frequency measuring apparatus
IPC: G01R23/10
Filed: 1973-01-22
Abstract: 1420251 Frequency measurement; harmonic determination TAKEDA RIKEN INDUSTRY CO Ltd 22 Jan 1973 [22 Jan 1972] 3132/73 Heading H3H Frequency measuring apparatus for use in the SHF bond comprises means for determining the harmonic of a reference oscillator to which a variable frequency oscillator is locked and means for determining the unknown frequency from the difference between it and the VFO frequency. Harmonic determination.-Variable frequency oscillator Ov is locked to the dth harmonic of reference oscillator Os (frequency fs) by phase difference detector B. An auxiliary oscillator Ot operates at a slightly different value to the reference oscillator. Frequency converter Hs produces an output of frequency #f equal to the difference between fs and the auxiliary oscillator frequency and counter Nh is gated to count pulses from converter Ht for one cycle of frequency #f. Converter Ht produces the difference between the dth harmonic of fs (from Ov) and the dth harmonic of the auxiliary oscillator frequency. This frequency is d.#f and the resulting count in counter Nh is the harmonic number d. Unknown frequency determination.-The unknown frequency fx is applied at F to converter Hv which has as other input the VFO frequency d.fs. The output frequency of Hv is therefore fx-d.fs. This frequency is further reduced by fa (from oscillator Oa) and fb (from Ob) and is fed to counter N1 for 10<SP>n</SP> seconds where it is on positive or negative integer. The counter count is 10<SP>n</SP>(fx-dfs-fa-fb) and from this, fx can be determined as fs, fa and fb are known and d is shown in counter Nh. In an alternative embodiment the VFO frequency is swept until the output of converter Hv is in the pass band of a tuned filter. The sweep is then stopped and the oscillator frequency locked to the nearest reference oscillator harmonic.

Abstract: 856,992. Stone-cutting machines. FITZPATRICK, H. J. (Clipper Manufacturing Co.). Jan. 30, 1957, No. 3193 /57. Class 124. A masonry saw comprises a structure 72 manually operable to raise or lower a cutter assembly 22 to vary the distance of a cutter disc 32, driven by a prime mover 34, from a worktable 18 on a frame 10, a movable platform 24 swingably carrying the asssembly 22 to raise or lower it and a lever arm 112 having a pedal 114 and pivoted on the structure 72 on a shaft 116 whereby the assembly 22 may be swung about a releasable shaft 52. The assembly 22 is manually raised or lowered by a wheel 98 through a device 92, attached to the structure 72 at 108, so that the latter, attached to the frame 10 at 90, may be reciprocated at the point 108. Rods 42 attached to the structure 72 at 88 thus raise or lower a support 44 for the assembly 22 mounted rigidly thereon and pivotally connected to the legs 14 of the frame through linkage 48, and hence raise or lower the assembly 22. The device 92 comprises a screw 94 rotating in a nut 102, acting as follower means, and carried by a bracket 96 on the frame 10 to be operated within tubes, 104 and 106 by the wheel 98. Operation of the pedal 114 and lever 112 actuates a rod 132 passing through a hole 46 in the support 44 and resiliently connected to the platform 24 of the assembly 22 pivoting by means of the releasable shaft 52 in notches in the support 44. The bracket 96 is attached to a spring 141 acting to raise the lever 112 so that the rod 132 tends to pull down the platform 24 to raise.the disc 32, a cross-pin 166, Fig. 4, in the end of the rod 132, (moving in a hole 156), engaging a bight 154 in a bracket 152 attached to the platform 24. On depressing the pedal 114 to lower the disc 32, the cross-pin 166 is free to move upwardly from the bight 154, and a spring 158 on a shoulder 160 engages the lower face of the bight 154. Through slots 180 in a leg 182, Fig. 9, of the bracket 152 pass legs 178 of a latch 176, through which pass a shaft 172 (with a finger 184), turnable by a crank 170 to hold by spring means the legs 178 between the platform 24 and pin 166 to make the spring 158 ineffective.

Title: Improvements in and relating to aero-thermodynamic ducts adapted to operate at supersonic speeds

Filed: 1954-02-05
Abstract: 747,705. Aircraft cabins; boundary layer control on jet-propelled aircraft. LEDUC, R. Feb. 5, 1954 [Feb. 6, 1953], No. 3453/54. Class 4. [Also in Group XXVI] An aero-thermodynamic duct for a ram-jet or a gas-turbine engine moving at supersonic speed has an annular diffuser entry defined by an outer tubular shell 11 and a central substantially coaxial core 4 which projects forwardly from the open leading end of the shell, in which the forwardly-facing portion of the core is of ogival section with its circumferential line of inflexion, at the point of maximum slope of the profile, situated near to and preferably slightly down-stream of the plane of the leading edge of the shell, and the surface of the concave portion 4a of the core, and optionally at least an adjacent part of the convex portion 4b, is provided with distributed perforations or porosity in communication by internal passage means with the exterior of the shell 11 at a region where the external fluid flow is least disturbed and the static pressure approximates to that of the undisturbed ambient fluid. In the embodiment shown, applied to an aircraft body, the core is provided with a skin 8 supported from the core in any known way and perforated at the portions stated, the space between the skin and the core being connected with the outside of the shell 11, in the region of the maximum diameter of the latter, through a duct 9 and apertures 10, whereby the boundary layer of fluid is drawn off from the surface of the core and discharged. The front portion 3a of the core is in the form of a cone of small angle housing the pilot's cabin, and the boundary layer formed along this portion is drawn into an annular slot 17 at the front end of the space between the core 4 and skin 8. In another embodiment the concave curve of the core and skin is continued forward to a sharp point. The arrangement is such that the single shock wave produced by the vertex of a cone is replaced by a series of smaller shock waves produced along the concave part 4a of the core, the envelope of these waves being of small or vanishing curvature and situated outside the leading edge of the shell 11 ; the effect is a substantial increase in the compression efficiency over a wide range of Mach number. The front portion of the shell 11 may be perforated, as shown at 12, for removal of the internal boundary layer at that portion, and the section 11a may be movable axially, for example by piston-rods 15, to vary the crosssection of the inlet.
