Title: Wave-energy direction finders
IPC: G01S3/808
Filed: 1966-02-10
Abstract: 1,144,361. Radio and sound direction-finders. MOTOROLA Inc. 10 Feb., 1966 [3 March, 1965; 19 March, 1965], No. 5908/66. Heading H4D. In a direction-finder first and second transducers convert received waves to respective first and second electric signals, the transducers are spaced by less than half a wavelength at the maximum operating frequency, a circuit is responsive to the passage of waves from the first to the second transducer to develop a first pulse, another circuit produces a second pulse when waves pass from the second to the first transducer, and an indicator is differentially responsive to the two pulses. Direction-finding with low signal/noise ratio is possible since omnidirectional noise tends to cancel out. Radio and sound waves are mentioned. In one embodiment, Fig. 3, the zerocrossings of the waves are utilized; the output of each transducer after filtering and dipping yields a square wave (Fig. 4, not shown) fed to a monostable multivibrator 27, 28, the re-set input of a bi-stable multivibrator 25, 26 and an AND gate 30, 29. The output of a monostable multivibrator 27, 28 inhibits a corresponding AND gate 29, 30 for a time equal to between one half and unity times the period of the highest wave frequency. The AND gate outputs are fed as set inputs to the bi-stable multivibrators, the outputs from which are integrated in opposite polarity on respective capacitors 43, 48 provided with switches 44, 49 for discharge prior to integration. The duration of the output pulse from a monostable multivibrator may be restricted to discriminate against noise from directions other than that arc from which a wanted signal is expected. Two orthogonal or non-orthogonal systems are employed to remove ambiguity, Figs. 5, 6, 7 (none shown). A three-dimensional arrangement is outlined, Fig. 8 (not shown). In a two-dimensional arrangement for reducing "tilt error" two systems each comprising three receptors are employed, Fig. 9 (not shown). In another embodiment, Fig. 10, two transducers 110, 111 are spaced a quarter of a wavelength and connected as shown to multivibrators 113, 114 which are normally monostable but with input signals which occur with a time spacing less than that corresponding to internal re-setting, act in a bi-stable manner.

Abstract: 1,094,151. Route identification. ENGLISH ELECTRIC CO. Ltd. May 13, 1964 [Feb. 13, 1963], No. 5924/63. Heading B7N. Conveyances 10 which are to be diverted from a main overhead track 11 to a branch track via a set of points 12 are identified at a reading position 20 by magnetic proximity heads 21-24 disposed in predetermined unique positions on support members 20a, 20b, mounted on either side of the track which cooperate with similarly disposed metal inserts 16a, 16b, 17a and 17b disposed on support members 16, 17 mounted on the non-rotatable axle of the conveyance. The simultaneous presence of signals from the four proximity heads is sensed by gate 26 which supplies a signal via memory device 27 and amplifier 28 to a solenoid 29 which operates the points. After a delay sufficient for the conveyance to move over the points a delay device 30 generates an inhibit signal which cancels the output of the memory device and the solenoid moves the points to its normal position. The support members 16, 17 on the conveyance may be rotated to different angular positions to direct the conveyance to different branch tracks. Wheels 19 on the conveyance which bear against the inner vertical faces of rails 11 move into a gap restricted by plate 31 at the reading station and prevent the conveyance slewing during the reading process.

Abstract: 1399081 Image pick-up tubes ENGLISH ELECTRIC VALVE CO Ltd 28 Nov 1973 [7 Feb 1973] 5957/73 Heading HID The pyroelectric target of a camera tube, comprising crystal 10 of pyroelectric material, e.g. triglycene sulphate, having embedded therein a mesh of relatively high thermal conductivity, e.g. the copper mesh 12, to prevent the lateral dissipation through the crystal of heat from the image, with consequent decrease of resolution, by conducting such heat directly to a heat sink in the form of a mounting ring (not shown) secured to the mesh beyond the crystal. Either the mesh 12, or a carbon layer 18, may be employed as the signal plate for the target, the layer 18 also increasing the thermal absorption of the image by the crystal. The target is made by lowering the crystal on to a mesh which supports a drop of water (Fig. 1, not shown); the water dissolves a portion of the crystal, to leave the mesh within the crystal upon evaporation of the water.

Title: Improvements in producing sintered, shaped bodies from powdery ferrous material
IPC: C22C33/02
Filed: 1945-03-09
Abstract: 600,829. Powder metallurgy. AMERICAN ELECTRO METAL CORPORATION. March 9, 1945, No. 5974. Convention date, Feb. 11, 1944. [Class 83 (iv)] In a method of making articles from ferrous powder, oxides are removed by adding rhenium, molybdenum or tungsten to the ferrous powder mixture and heat treating at a temperature below the final sintering temperature until the oxides present have combined with the added metallic deoxidiser and the oxides so formed have volatilized and escaped, after which the temperature is increased to complete the shrinking of the mass. If molybdenum is used, onehalf per cent will in general be sufficient, but greater amounts may be added. The molybdemun to be added may be pre-alloyed with a component of the mass and then comminuted and mixed with the balance of ferrous powder. If the added molybdenum is required to serve both as deoxidiser and carbidiser, the deoxidation process is first completed, the temperature then increased to the range at which excess carbon in the mass combines with excess molybdenum and finally the sintering temperature is reached. With rhenium the deoxidation occurs at much lower temperatures, at about 450‹ C. Due to the higher sublimation temperature of tungsten oxide, tungsten can be used only with essentially ferrous masses, the critical shrinkage temperature of which is higher than the sublimation temperature.

Abstract: 1,113,466. Fuel elements. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. 3 Feb., 1967 [11 Feb., 1966], No. 6260/66. Heading G6C. [Also in Division F2] A fuel element of the kind which has a cluster of fuel rods disposed within a sleeve, e.g. of graphite, and intended to be positioned in a reactor fuel channel in end-to-end association with one or more similar fuel elements, is characterized by the provision of sealing means effective between its sleeve and that of an adjacent fuel element over a finite axial length of a cylindrical surface of at least one of the sleeves so as to counter leakage between the sleeves during operation when they are coaxial and also in the event that they become tilted relative to one another on prolonged normal operation of the reactor. Two adjacent sleeves 1, 2 are shown in Fig. 2, the upper sleeve 1 having an annular recess 4 in a portion 3 of enlarged thickness, radial slots 7 in the peripheral wall of the recess 4 each being provided with a stainless steel split ring 8, the splits of which are annularly staggered. The upper end of the sleeve 2 has a portion 9 of increased internal diameter such that it is able to fit with clearance the annular recess 4. The peripheral edges 101, 11<SP>1</SP> of the portions 3. 9 are inclined to the longitudinal axes of the sleeves 1, 2. The rings 8 are fully accommodated within the slots 7 at normal temperatures and project outwardly beyond the wall of the recess 4 at reactor operating temperatures (600- 700‹ C.) to contact the internal peripheral surface of the portion 9. In an alternative embodiment' (Fig. 3, not shown), the sealing means is provided by an external screwthread in the recess wall which is engaged by a spiral of stainless steel wire, while in another embodiment (Fig. 4, not shown) a stainless steel ring having a vertically-halved figure eight cross-section is disposed in a groove formed in the recess wall. Fig. 5 illustrates yet another embodiment, the internal surface 18 of the portion 3 of the sleeve 1 being provided with rectangularsection, circumferentially-extending grooves 19 and a stainless steel shroud member. 21 being retained in loose engagement in " cold " conditions on the sleeve 2 by virtue of a screwthreaded ring 12<SP>1</SP> having circumferentiallyextending grooves 20 being superimposed over a flange 22 at the lower end of the shroud member 21 (the reactor coolant flowing vertically upwards through the sleeves). At reactor operating temperatures, the shroud member 21 expands to contact the surface 18 and ring 12<SP>1</SP> and the grooves 19 and 20 form with the shroud member 21 a labyrinth-type seal. In a further embodiment (Figs. 6 and 8, not shown), the sealing means is constituted by an annular slot in each of abutting ends of the adjacent sleeves and by a single cylindrical sealing shim engaging both walls of both slots. The sealing shim may be corrugated in cross-section.
