Filed: 1975-07-24
Abstract: 1484095 Producing formcoke PEABODY COAL CO 24 July 1975 [28 April 1975] 31007/75 Heading C5E A process for producing formcoke comprises charring green coal in a pretreatment carbonizer 4 having an oxidizing atmosphere using heat produced by combustion of the volatiles evolved from the coal, further reducing the volatile content of the char by feeding it through a post treatment carbonizer 22 having a reducing atmosphere, cooling the char at 26, mixing the crushed char with pitch at 30 and forming briquets at 40, curing and cooling the briquets by passing them through at least one of the carbonizers and the cooler 26 with the green coal, and separating the cooled briquets from the char using, for example, a screen 27. In the preferred process, the green briquets are recycled with the coal by passage through both carbonizers, being heated in the first (which is a horizontal chain grate conveyer type) to 2000‹ F. and in the second (which is a shaft furnace) to 1700-2200‹ F. The pitch used for briquetting the char may be derived from the volatile substances evolved from the green coal.

Title: Wave guide attenuator
Inventor: MILNE KENNETH
IPC: H03H7/24
Filed: 1950-12-21
Abstract: 692,591. Wave-guides. BRITISH THOMSON-HOUSTON CO., Ltd. Dec. 14, 1951 [Dec. 21, 1950], No. 31131/50. Class 40 (viii). A wave-guide attenuator comprises a length of cylindrical guide having a stub guide of rectangular cross-section connected thereto, the longitudinal axis of the stub being perpendicular to, and its long side being parallel with, the longitudinal axis of the cylindrical guide, and the stub guide terminating in a matched load. As shown, waves from a transmitter 1 are led through a rectangular guide 2. The attenuator consists of three lengths 4, 5, and 6 of circular section guide. The length 5 bears a stub 9 with load 10, and is mounted to rotate with respect to the other sections at flanged joints 7. The rectangular guide 2 causes the transmitted waves to be plane polarized and thus rotation of section 5 varies the amount of energy which branches off into guide 9 and is absorbed in load 10. Further, a metal strip 11 is placed in section 15 so that the output waves are polarized in a plane that rotates with section 5 and thus a varying amount of energy is dissipated in branch 12 and load 13 attached to section 6. The load 3 connected to the attenuator by a further rectangular guide 2 receives a proportion cos A of the original energy where A is the angle of rotation of section 5. If desired the apparatus may be made symmetrical by adding a stub and load to section 4 and providing loaded stubs on each side of strip 11 m section 5.

Title: A new or improved apparatus for finishing surfaces of turbine type blades
IPC: B24B21/00
Filed: 1952-12-10
Abstract: 719,124. Grinding turbine blades. JAMESON, J. L. Dec. 10, 1952, [Dec. 12, 1951.] No. 31303/52. Class 60. A machine for finishing the surface of a turbine blade 3 comprises a blade holder 90, Fig. 2, a die 2, means to move an abrasive band 4 between the blade and the die and fluid-pressure operated mechanism to effect relative member between the latter two members firstly at one rate until they reach a position with their surfaces close to one another and then at a reduced rate which is maintained throughout the finishing operation. In the preferred embodiment, the holder 90 is secured to a movable hydraulic cylinder 91 sliding on a stationary piston 92, Fig. 5. The cycle of operations is initiated by closing a switch 96 to displace a solenoid operated valve 122 which connects a line 95 to a pump 99 through a line 98<SP>1</SP> so that the cylinder 91 moves down quickly. Exhaust from the upper side of the cylinder takes place through a line 94, a valve 109 in a regulating unit 119 and a line 112 which is connected with a discharge line 113 through the valve 122. This action continues until a cam block 107 adjustably mounted on the cylinder 91 closes a micro-switch 108 to displace a solenoid operated valve 104 which permits fluid from the pump 99 to close the valve 109. The cylinder 91 now exhausts through an adjustable needle valve 110 so that its rate of movement is reduced during the abrading operation. The movement of the cylinder 91 is reversed when a second adjustably mounted cam block 114 opens a second micro-switch 115 to operate the valve 122 which connects the line 95 to the discharge line 113 and the line 112 to the pump 99. Fluid from the pump passing through the line 112 opens a valve 117 and hence bypasses the valve 110. A self-recuperating dashpot 126 having a plunger 123 for engagement by a lug 133 on the cylinder 91 cushions the final part of the rapid downward movement of the latter. The abrasive band 4, Fig. 2, passes over guide rollers 4<SP>1</SP> and is trapped between a roller 4<SP>2</SP> and a driven band 4<SP>4</SP> by which it is driven. Convex and concave blade surfaces can be finished and a guide 4<SP>3</SP> is arranged to exert sufficient drag on the abrasive band to provide a slack portion which can be pressed into the concavity of the die block when convex surfaces are being treated. The blade 3, Fig. 7, has one end located in a socket 136 and its other end held by a screw operated releasable swinging clamp 137. A jet 130 delivers oil to the band. Specification 591,890 is referred to.

IPC: F22B37/54
Filed: 1936-11-16
Abstract: 481,988. Steam - boiler blow - down apparatus. POLLAK, J. E. (Electro-Chemical Engineering Corporation) Nov. 16, 1936, No. 31340. [Class 123 (ii)] " Light " or impure boiler water concentrated at or above a fixed level always above the normal level of the " compact " water is collected from this fixed level and drained away with collapsed foam but without substantial discharge of steam or compact water. A collecting basin 21 rigidly 'suspended so that its top edges are above the normal water level of a locomotive boiler has a pipe 24 leading collapsed foam to a blow-off valve 26 which may also receive water from the mud ring, steam and water passing through an outlet pipe 27 to a separator 28 and sludge water being discharged through a pipe 30 to the road bed. The blowoff valve is opened by steam supplied through a pipe having an operating valve 35 in the cab and the amount of discharge may be controlled by valves 24a. In a modification, buckets 40, 41 of different heights are arranged in the steam space with siphon discharge pipes 44, 45 depending therein and connected through steam traps to a blow-off valve 50, Fig. 7. Water collecting in and discharged from bucket 40 alone is ordinarily insufficient to depress a piston 60 of the blow-off valve and flows through a duct 65 to the outlet 27. Foam continuing to develop periodically above the level of bucket 40 accumulates in bucket 41 and also discharges to the blow-off valve whereupon the combined streams depress the piston which forces a ball valve 69 off its seat to allow sludge water to be blown to the outlet 27 through an opening 56. Another arrangement provides for the separate discharge from bucket 40 through a second separator.

Abstract: 641,011. Supersonic inspection devices. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 26, 1947, No. 31340. Convention date, Nov. 26, 1946. [Class 118 (ii)] [Also in Group XXXIX] A piezo-electric crystal holder suitable for use in testing a conductive solid material 6 for the presence of internal defects by supersonic energy comprises a metallic cylindrical casing 1., 3 with a circular aperture 2 in the end which is held in contact with the material and means for mounting the crystal 19 in the aperture by a spring support so that the pressure between the crystal and the material is maintained constant. The crystal is mounted on a metal plate 20 attached to a piston-like dielectric annular disc 21, the assembly being urged towards the aperture by a compressed spiral spring 23 one end of which bears on the metal plate 20 and the other end being seated in a metallic dish 12 mounted on the end of a hollow cylindrical dielectric member 9. The spring also serves to make an electrical series connection between the crystal and an inductance coil 8, the inductance being adjusted to resonate with the crystal by the adjustable brass or powdered-iron core 13. The low impedance of the series resonant combination enables it to be matched to a coaxial line feeder coupled to the connector 11 and the voltage applied to the crystal will be greater than the line voltage. The outer surface of the crystal is connected to the outer conductor of the connector via the material 6 and casing 1, 3. When using the pulse method of testing, a D.C. waveform as shown in Fig. 2 is applied to the coaxial line to produce recurrent damped wave trains, Fig. 3.

Abstract: 1389208 Electric alarm timepiece R C A CORPORATION 30 June 1972 [5 July 1971]  31464/71 Heading G3T An alarm timepiece incorporates subdued (drowse) and full alarm facilities and an alarm cycle renew switch 2 to reactivate the subdued alarm condition. The subdued alarm may be produced by a radio 8 for the whole of a delay or drowse period initiated by a time switch 5 at a pre-set time. The delay period duration is dependent upon the charging time of a capacitor 23 in a delay circuit 1 including a Schmitt trigger. At the end of the delay period a transistor 22 conducts and the base of transistor 21 offers a high resistance to mains A.C. fed via C30 R31 and current flow through 21 responds, forward biasing a diode 27 to pass clipped A.C. to the A.F. stages of the radio. Thereby the full alarm is produced and will continue until C23 is discharged. During the drowse delay period Tr 21 is saturated and diode 27 blocked so the full alarm is prevented. Manual operation of switch 2 causes renewal of the delay period and subdued alarm instead of the full alarm, when desired.  A three position switch enables the switching ON of the radio when desired. A "sleep" switch 9 can be set to automatically switch OFF the radio after say half an hour's play.
