Abstract: 1,099,054. Making dynamo-electric machines; electromagnetic forming. GENERAL ELECTRIC CO. Nov. 30, 1965 [Nov. 30, 1964], No. 50843/65. Headings B3A and B3Q. In a method of effecting a desired placement of electrical conductor means carried by an accommodating member, the placement is effected by a surge of induced current flow in the conductor means, the current flow being induced by passing a surge of current through a coil in transformer relation with the conductor means. A coil accommodating member 21 carries a primary winding 23 which is fixed in relation to a stator core 20. The conductors 25 of the winding 23 define magnetic poles aligned radially with the pole axes 26-29 and simulate the magnetic poles defined by coil groups 30-33 of a winding 34. The winding 34 is short circuited by joining leads 35, 36. A power pulse source 41 produces a surge of current flow in the winding 23, thereby inducing a corresponding surge in the winding 34 and the electromagnetic forces act on the conductors of the latter to push them towards the bottoms of the slots 42. Simultaneously the coil end turn portions of the winding 34 are pushed back towards the end faces of the member 21. The windings of an armature (105) may be similarly compacted by placing it within a winding accommodating member (107), Fig. 13 (not shown). In alternative embodiments the windings may be extracted from the slots, by means of induced magnetic attraction.

[Also in Division F2] Lubrication is started and stopped at two predetermined counts of working cycles of a machine, failure of the lubricating system giving an alarm and stopping the machine. Each machine cycle operates a contact 20 to operate coil 182 to step down a counter 18 from a preset value. When the counter reaches a predetermined low value, contact 183 closes to energize lubricate relay 16 over normallyclosed contact 281, and lubrication ensues. Relay 16 holds over contact 162 until oil pressure has built up when switch 14 changes over and coil 181 resets counter 18 to its original value. If switch 14 does not change over then the count continues to zero when contact 184 opens. Fault relay 28 then releases to bring up an alarm and/or stop the machine and release lubricating relay 16. A float switch 26 opens if the lubricant level is low, whereupon fault relay 28 releases. The machine can be lubricated by operation of switch 22.

Abstract: 1487407 Shearing; punching; caulking M ISHIHARA 10 Dec 1974 [14 Dec 1973 30 May 1974] 53293/74 Headings B3W and B3U A fluid-pressure operated device, e.g. for shearing steel bars, comprises a cylinder 20 divided by a piston 21 into a high pressure chamber 23 and a low pressure chamber 17b, a spring 40 urging the piston towards the chamber 23. A pump 31 feeds fluid to the chamber 23 to move the piston 21 and thus a shear blade 57 through a working stroke which is terminated by the opening of at least one return valve 41 when valve rod 43 engages a stop 49. Raising of the valve head 46 from an opening 47 in the piston 21 allows fluid to flow through passage 45 from chamber 23 into chamber 17b. As pressure in chamber 23 decreases a spring 48, compressed by the stop 49 before the rod 43 contacted it, moves the rod 43 to the right and a spring 50 holds the valve open until the piston 21 has been returned by the spring 40 to Fig. 1 position. The pump 31 comprises a cam rod 32 eccentrically mounted on a motor-driven shaft 26 and acting on a plurality of plungers 34 to force fluid from reservoir section 17a through passage 37, one-way valve 38 and passage 39. A safety valve 60 in a passage 59 can be opened manually to allow fluid to pass from chamber 23 to chamber 17b so that material which has proved to be too hard to shear may be removed. A flexible bag 63 compensates for variation in the volume of the reservoir during reciprocation of the piston 21. Alternatively, a piston (72), Fig. 5 (not shown), in a cylinder (69) communicating with the reservoir is movable against the pressure of light spring (73) in response to volume variation. A combination of flexible bag (74) and piston (75) is shown in Fig. 6. The shear blades 57, 58 may be replaced by a punch and die or caulking tools.

Abstract: 1,124,136. Measuring temperature. EUROPEAN ATOMIC ENERGY COMMUNITY. Dec. 16, 1965 [Dec. 28, 1964; Sept. 2, 1965], No. 53497/65. Heading G1N. A temperature is measured by allowing a length of cold-worked conductive wire to attain the temperature, removing it from the temperature field, and traversing a known concentrated temperature, above the unknown temperature, along the length of the wire at a known speed while measuring the voltage developed between its ends. Theory. Stresses in the wire due to coldworking are relieved by annealing at a high temperature, and the relief of such stresses is accompanied by generation of a voltage. The voltage generated during annealing is stated to be a substantially linear function of the temperature to which the wire was previously exposed, over a wide range of temperatures. If the generated voltage is plotted against time as the concentrated field traverses the wire the original temperature distribution over the length of the wire may be determined. The wire is preferably allowed to cool after removal from the unknown temperature field. The concentrated temperature field may be generated by means of a rod 4 having a transverse aperture containing a ceramic bead 6 through which the wire is drawn. Both ends of the rod 4 are heated by windings 5 and cold air is blown over the wire at each side of the aperture, from tubes 7, 8. The flow of air is accurately controlled to maintain the temperature constant. Guides 11, 12 are also cooled by further air tubes 13, 14. Radiation shields 9, 10 are provided. The rod 4 and the radiation shields are of stainless steel. The wire may be of platinum for temperatures up to and above 1000‹C., or of silver for temperatures below 200‹C. Each length of wire can be used only once. Calibration. The first two wires of a batch are used to calibrate the recording instrument by exposing them to known temperatures. This calibration applies to all other wires from the same batch.

On the inner side of the lid 11 is a felt pressure pad 15 and an intensifying screen 16. The bottom panel 13 is also lined with a pressure pad 19 and an intensifying screen 18. Between the two intensifying screens is located the X-ray film sheet 17. At one end of the cassette the pad 15 and screen 16 are cut away to allow space for insertion of the tab 22A. The light-seal assembly 29 for the slot 28 comprises two felt-like flaps 31, 32 separated by a flexible tongue 33, all biased upwards by a leaf-spring 34. A lead blocking member 36 is set into the bottom panel 13 so as to shield from the X-rays falling on the remainder of the film on which the indicia are to be marked. The tab 22A is a transparent T-shaped piece of a plastics material. The label 25A marked with the required indicia has on its under side a layer of pressuresensitive adhesive 40, covered with a protective sheet 41 which is removed when required. The phosphorescent material may be copper-activated zinc suphide, and is coated on to the label itself or on to the plastic tab. Before insertion into the cassette it is activated by exposure to radiation which may be simply the ambient light. It is left in the cassette for about four seconds, which is sufficient for the afterglow to imprint the indicia on the film, and then removed.

Abstract: 1345199 Infusion apparatus L ROSSI 26 Nov 1971 [1 Dec 1970] 54963/71 Heading A4E A mechanical unit for brewing infusions, mainly expresso coffee, comprises a first cylinder 1, in which first and second pistons 6, 21 are movable with the space between them forming an infusion chamber, and a second cylinder 30 having the same diameter as the first which is movable between a first position coaxial with the first cylinder 1 from which position coffee is fed into the infusion chamber and a second position in which coffee is fed into the second cylinder 30 through a mouth 31, the second cylinder moving between two walls 28, 29 fitting flush against its ends. The second cylinder 30 has a section of its side wall (39) Fig. 9 (not shown) movable against the bias of a spring (40). Infusing water is supplied to the coffee through a channel 10 and filter 24 and the resulting brew is passed out through a filter 25 and a channel 11. A hot water jacket 3 surrounds the infusing chamber. Hydraulic pressure is released in a chamber 16 to move a piston 17, connected to the piston 21 by a stem 20, against the bias of a spring 19. Similarly hydraulic pressure is applied in a chamber 9 to move the piston 6. The pistons 6 and 21 move to form a clear passage for the second cylinder 30, now containing coffee, to move into the said first position Fig. 3 (not shown); this movement removes any spent coffee attached to one of the filters 24, 25. The piston 17 is then driven against the spring 19 by hydraulic pressure and the pressure in the chamber 9 is released to drive and compress the coffee into the first cylinder 1. The second cylinder is returned to its second position for loading coffee, the stem 21 passing through the movable sector 39 of the cylinder 30 Fig. 8 (not shown). A valve assembly (47) Fig. 9 (not shown) may be incorporated in a duct 14 leading to the chamber 9 to prevent movement of the piston 8 until a fixed pressure is reached thus subjecting the coffee to a known compacting force. The chamber 9 may also contain a spring (48) which biases the piston 8 when the piston 6 is retracted into the cylinder 1 so that any change in volume of the coffee during infusion is resiliently balanced by the spring (48). An alternative embodiment of the unit has the cylinders in a vertical plane with the mouth 31 being attached to the uppermost of the walls 28, 29. Provision may be made for automatic operation of the apparatus. Two apparatus may be operated simultaneously from a surge hot-water feed source.

Abstract: 1436786 Radio navigation STANDARD TELEPHONES & CABLES Ltd 27 Nov 1973 54970/73 Heading H4D A radio navigation receiver for use with a beacon in which there is commutation of a source of a first frequency to the elements of linear array in turn, so as to simulate constant velocity uni- or bi-directional scanning of said array, and in which there is simultaneous transmission of a reference signal of a second frequency, comprises first means for deriving a Doppler beat information signal from the received signals which includes a filter having a passband covering the range of Doppler beat frequencies of the direct path signal and not those of a multi-path signal, for example, a signal reflected from the ground in an elevation guidance system. The receiver also comprises second means for determing the time at which each scan is commenced, third means for determining the frequency of the Doppler signal during each scan, and fourth means under the control of the second means for inhibiting the operation of the third means at the commencement of each scan for at least part of the transient response time of the filter. As described, there is an R.F. input stage 1, Fig. 2, where the received beacon signals are changed in frequency and amplified to be passed to a detector stage 2, whose output is the Doppler beat waveform. After the stage 2 there is a bandpass filter 3 covering the range of required Doppler beat frequencies, to select the direct path signal in preference to multi-path signals. The next two stages comprise a zero crossing detector 4 and a counter 5 to produce an output which is fed to a centre zero D.C. meter or other form of bearing (elevation) information display. The remaining stages are a scan timing derivation stage 6 having as input either the Doppler beat waveform from the detector 2, or the output from the R.F. stage 1, from either of which the instant of commencement of each scan may be determined, and a control stage 7 arranged to inhibit operation of the bearing signal count, i.e. to gate the signal in sympathy with the scan rate. Alternatively, scan phase information may be transmitted on a sub-carrier of the reference signal of the beacon, for operation of the stage 7. Instead of the zero crossing detector 4 there may be employed a computing period counter wherein clock pulses are counted for the same proportion of the period of the Doppler beat signal waveform. As shown in Fig. 3a, there is a 180 degree phase shift at the end of a scan n of the input beat signal followed by a scan n+1. Fig. 3b shows the filter response to the scan n only, Fig. 3c its response to the scan n + 1 only, while Fig. 3d shows the combined signal. In a region X the filter output is ringing near the filter centre frequency, whereas in the region Y the filter output frequency is substantially that of its input. Accordingly, the counter 5 is inhibited by a gating waveform as shown in Fig. 3e, e.g. for 25% of the scan time. Specifications 1,225,190 and 1,234,541 are mentioned.
