Title: Apparatus for cracking a structure
Inventor: MALET MICHAEL ANLEY
IPC: E21C37/18
Filed: 1966-12-19
Abstract: 1,216,654. Heating and cracking concrete and rock surfaces. A. MALET, A. WATSON and A. J. CHABOWSKI. 19 March, 1968 [19 Dec., 1966], No. 56838/66. Headings E1F and E1G. [Also in Divisions H3-5] In the event of excessive force e.g. due to explosion, on the radiating end 27, 28 of the waveguide 30 of a microwave concrete or brick cracking apparatus, the waveguide 30 is swung clear of the structure being cracked to prevent damage. The apparatus comprises two wheeled vehicles one, not shown, acting as a power pack for the other 2 which carries the magnetron 4, a traction motor and the remainder of the equipment. The vehicle 2 may be driven in forward or reverse through a clutch, pulley 48 and belt 47 or may be oscillated backwards and forwards through the clutch, crank 53, link 52 and adjustable pin 51A on wheel 51. The magnetron 4 is water cooled, the water being passed through a radiator 6 which is cooled by air from a fan 8. A thermostat switches the magnetron off should it become overheated and a regulator controls the power supplied. Microwave energy is passed from the magnetron through a system of rectangular waveguides 5, a flexible waveguide 21, a block 22, waveguide 35 to waveguide 30. Waveguide 35 can be omitted. The block 22 Fig. 4 is apertured at 34A and contains a cylinder 34 having a diametral passage therethrough. The passage contains one end of waveguide 35 and normally communicates through an aperture 22A in the block with flexible waveguide 21. The cylinder 34 is rotable about the axis 34B so that waveguides 35, 30 may occupy the position shown in chain lines. A snap-action tension spring 60 and hydraulic damper not shown controls the pivotal movement and the waveguides are arrested in a vertical position by spring biased stops 22B. A microswitch 33 actuable by the waveguide 35 switches the magnetron off as soon as the'waveguide 35 is raised. An eccentric 32 adjusts the height of the head 27, 28 above the structure being worked on. In an alternative construction waveguides 30 and 21 are pivoted together, directly and waveguide 30 is raised against the action of a dashpot on the occurrence of an explosion. The end of the waveguide 30 is inclined at an acute angle to the horizontal and microwave energy is directed downwardly through a hole in a metal plate inserted in the end. An asbestos sheet covers the hole and prevents dust &c entering the waveguide. The end of the waveguide is surrounded by a horizontal circular array of square copper gauze to prevent lateral microwave leakage. A skirt 28 of brass wires brushes the surface of the structure being cracked to prevent radiation leakage. A microswitch carried by the waveguide 30 turns off the magnetron should the head 27, 28 be excessively raised from the structure.

Filed: 1970-12-03
Abstract: 1335838 Colour television SONY CORP 3 Dec 1970 [8 Aug 1970 (2) 20 Aug 1970] 57556/70 Heading H4F A colour television receiver for receiving PAL or NTSC signals demodulates only every second line of the received signal, a one line (or an odd multiple of one line) delay line 23 being used to insert a delayed signal in place of those lines of the received signal which are not demodulated. The delay line 23 either precedes or follows a switch 22 operated at the end of each line period under control of a flip-flop 51 to pass the desired signals to demodulators 24, 25. The phase of operation of switch 22 is controlled by a phase comparator 38 so that, e.g. for received PAL signals, the signals passed to demodulators 24, 25 are those lines where the R-Y modulation axis is at + 90 degrees relative to the B-Y modulation axis. In the embodiment of Fig. 8 phase comparator 38 receives a burst gating signal from 40, the received chrominance signal, including swinging bursts, from band pass filter 21 and a continuous signal from 90 degree phase shifter 43 connected to a continuous wave generator 42 controlled by the separated bursts contained in the output of switch 22. Phase comparator 38 (also Fig. 9, not shown) produces zero and negative outputs on alternate lines if switch 22 is operating in the desired phase, and zero and positive outputs if switch 22 is operating in antiphase, and in the latter case this causes change over of flip-flop 51 to obtain the desired operation of switch 22. In alternative embodiments phase shifter 43 is connected directly to the output of switch 22, or to the output of burst gate 41, and in the latter case the input from 40 to phase comparator 38 is dispensed with. In an alternative embodiment (Fig. 15, not shown) reference oscillator 26 is controlled by bursts separated from the output of band-pass filter 21 and phase comparator 38 receives inputs from the reference oscillator 26 and from the burst gate connected to the band-pass filter 21 to achieve correct operation of switch 21. Two reference oscillators (26a, 26b, not shown) may be used to be controlled respectively by bursts separated from the outputs of band-pass filter 21 and delay line 23, a second switch operated in synchronism with switch 22 being provided to connect the reference oscillator outputs alternately to the demodulators.

The cuff 40, preferably of ptfe, is clamped adjacent a selflubricating guiding ring 39 by a ring 42, screwed into a bore 32 and acting through an 0-ring 41. The lip seal 43, having three sealing lips 43c, is positioned by a screwed ring 44, a support ring 47 further being provided. The suspension unit includes a cylinder head portion 5 bearing a hollow plunger 4 within the working cylinder 1, the piston-rod 3 sliding on the plunger 4 and having a piston 2. Elastic membranes 8, 17 define closed compressed air spaces 9, 18 and oil reservoirs 7, 16. In operation of a vehicle including the unit, reciprocation of the piston 2 causes oil to be drawn into the cylinder 1 from the reservoir 7 through passages 10, 11, a chamber 6 and non-return valves 10a, 11a. Oil from a cylinder space 13 is forced through a channel 15 into the reservoir 16 causing a pressure build up on the membrane 17, the air space 18 acting as a pneumatic supporting spring. Continued pumping of oil into the upper cylinder space 14 acts on the piston 2, causing the unit to expand until the piston 2 uncovers an aperture 20 leading to an internal annular passage 19 within the plunger 4, a connecting passage 21 leading the oil back to the reservoir 7, so that further expansion is halted, the unit taking up an equilibrium position with the passage 20 just uncovered. Valved passages 2a, 2b through the piston allow for contraction of the unit if extended beyond the equilibrium condition, and passages 25, Fig. 2, (46), Fig. 3 (not shown), within the wall of the cylinder 1 connect the chamber 35 of the sealing arrangement to the oil reservoir 7, so maintaining the pressure in the chamber 35 at a level below that in the cylinder space 13 adjacent the sealing arrangement.
