Title: Improvements in high frequency duplex signalling systems
IPC: H04B1/56
Filed: 1929-05-16
Abstract: 312,079. Lorenz Akt.-Ges., C. May 18, 1928, [Convention date]. Duplex signalling; secret signalling systems; thermionic generators and modulating systems.- In duplex high-frequency signalling, for transmission undamped high-frequency oscillations are produced, periodically interrupted at an inaudible frequency, and modulated in accordance with the signal, and for reception the received modulated, interrupted oscillations are combined with locally produced interrupted oscillations. The undamped oscillations are produced by an oscillating thermionic valve 3 and are interrupted by supersonic oscillations produced by an oscillating-valve 15 and impressed on the grid of the valve 3 across a condenser 8, which is also supplied with signalling-currents from a microphone 17. The interrupting- oscillations, when the apparatus is used for reception, may be out of phase with the received signals, but tuning-means may be provided to bring them into phase. A piezo-electric crystal 19 regulates the frequency of the carrier wave, and a piezo-electric crystal 20 or a tuning- fork controls the frequency of the supersonic oscillations. The crystals at both stations may be changed simultaneously according to a prearranged system to ensure secrecy. A telephone receiver 12 is shunted during transmission, either manually by a key, or automatically by a third winding 21 inserted in a telephone transformer and connected in the microphone circuit.

Filed: 1974-04-08
Abstract: 1464944 Switchgear isolation MAGRINI GALILEO SpA 8 April 1974 [6 April 1973] 15418/74 Heading H1N A circuit breaker cubicle 14 is separated into two compartments by two parallel shutters 4 and 6 which isolate the line terminals 11 when the breaker carriage 16 is withdrawn. When the circuit breaker is moved into the cubicle a rib 10 on the carriage engages a link 9 pivoted at 12 and rotates it anticlockwise to lift the rod 7 and hence the shutter 6, thus bringing an aperture 20 in shutter 6 into line with the upper aperture 10 in shutter 4, whilst the bottom extremity of shutter 6 is lifted clear of the lower aperture 19 in shutter 4, thus exposing the line terminals (Fig. 2, not shown). As the circuit breaker carriage is moved yet further into the cubicle a pair of ribs 2 engage the front of the shutter assembly and push it towards the back of the cubicle so that the line terminals protrude through the apertures and engage with the circuit breaker contacts (Fig. 3, not shown); springs 3 are provided to draw the shutter assembly back again when the breaker is withdrawn, the shutter 6 then dropping back into place, either by gravity, or with spring assistance. A latching device may be provided to lock the circuit breaker to the shutter 4.

IPC: G02C1/02
Filed: 1929-05-17
Abstract: 328,137. Metzler, J. May 17, 1929. Spectacles and eyeglasses. - The lenses of rimless spectacles and eyeglasses are secured by a clamp made of two parts, one of which is movable in relation to the other to secure lenses of any desired thickness. The back of the jaw of the clamp part 3 is made of prismatic or similar form, being sunk into the edge of the lens and providing two surfaces for the engagement of doublesided grooves in the movable part of the clamp. A number of forms of the invention are described, of which that shown in Figs. 2 and 3 is typical. The stationary part 3 has a vertical guide 8 provided with two faces 10 fitting a recess 13 in the periphery of the lens 12. The movable part 1 through which the clamping-screw passes engages the vertical faces 10 by the sides of a groove 11 as shown, securing it against lateral movement. The forms of the vertical faces and grooves may be varied or the grooves may be in the stationary part and the faces formed on the movable part.

Title: Electron probe instruments
IPC: H01J37/18
Filed: 1971-05-18
Abstract: 1398513 Electron microscopes W B D DRAYTON 16 May 1972 [18 May 1971] 15522/71 Heading H1D [Also in Division H4] A scanning electron microscope comprises 5 Al blocks on a support structure, the first and last of which can hinge down to permit access to a horizontal bore passing through the blocks. A rotatable disc 18 of PTFE is mounted in a recess in one end block at 45 degrees to the microscope axis. Two openings in the disc receive specimen holders 21. A holder is initially placed in the left hand opening where is is urged by springs 22 to a partially retracted position clear of the block thereby allowing the disc to rotate. The right hand holder is pushed into the microscope by a lever 25 and to position controlled by a bolt 27. The specimens can be rotated and moved by handles 35. After examination the handle 25 is released and the disc rotated 180 degrees by an electric motor. The pressure of the 1.h. specimen is reduced to 10<SP>-2</SP> torr via passage 32 and as it rotates to the ex. amination position the pressure is further reduced to 10<SP>-4</SP> torr. Thus on reaching the examination position the pressure is rapidly reduced to 10<SP>-6</SP> torr and the specimen can be immediately examined. The microscope detector may be sensitive to secondary electron emission, X-rays or specimen current. The filament of the electron gun is adjustably mounted on gimbals. The microscope output is displayed on a C.R.T. with a control system which allows the area of specimen that is scanned to be adjusted without moving the specimen (see Division H4).

Abstract: 354,422. Portable drilling andtapping machines. PASS, E., Station Works, Denton, Lancashire. May 21, 1930, No. 15570. [Class 83 (iii).] A machine for drilling and tapping pipes, mains, or the like has a block a for attachment to the pipe secured to a housing f. The latter encloses a worm e and wormwheel d the tool spindle c being axially slidable and rotatably keyed to the wheel d. Carried within a tubular extension f<2> of the housing f is an internally threaded sleeve g which engages a nut g2 on the end of the tool spindle c. The sleeve g has teeth j, and a pinion having a slightly different number of teeth i is fixed to the worm-wheel d. A loosely mounted pinion k may be engaged as desired with the teeth i, j. The worm is driven by hand or power to rotate the tool spindle c. If the pinion k is in engagement the relative rotary movement of the nut g<2> and sleeve g gives an automatic feed to the tool b. The pinion k is disengaged to disconnect the automatic feed. The sleeve g has handles k<1> to permit of hand feed when the pinion k is disengaged. In a modification for a combined drilling and tapping apparatus the tool spindle c, Fig. 6, is slidable axially within the nut g<2>. The hand feed is actuated to move the inner end of the nut g<2> against a collar 1 on the spindle c. The automatic feed is then utilized and when a hole has been cut in the pipe the automatic feed is discontinued and tapping proceeds. When a collar 2 on the spindle c engages the outer end of the nut g<2> the tapping operation is completed.
