Title: Control device for a step-by-step motor
IPC: H02P8/02
Filed: 1973-09-17
Abstract: 1434947 Electronic timepieces SOC DE RECHERCHES EN MATIERE DE MICROMOTEURS ELECTRIQUES 17 Sept 1973 [20 Sept 1972] 43565/73 Heading G3T [Also in Division H2] To reduce the power consumption of a single winding stepping motor 5 driving the hands and calendar mechanism of a watch, the winding current is sensed by members 7, 8 following each closure of a switching transistor 4 by a control circuit 3, the latter circuit being responsive to the sensed current to switch off the transistor 4 when the winding current reaches a minimum value m corresponding to the time for the motor to reach a speed producing the maximum induced EMF, which speed is sufficient to overcome the load  torque'and so move a step. A frequency divider  2 supplied by a quartz oscillator (not shown) generates two trains of pulses A, A' having the same frequency but different widths, the width of each pulse A, Fig. 2, being sufficient to ensure the simultaneous driving of the hands and calendar  mechanism and the width of each pulse A' being sufficient to mask the first pulse of the two-pulse signal C, Fig. 2, produced by the member 8, so that the circuit 3 responds to the upward slope of the second pulse corresponding to the minimum m of the winding current characteristic B. Voltage and pulse waveforms at the points B, C, E, F, G, H and  D in Figure 3 are illustrated Fig. 4 (not shown) and discussed for a normal operation, wherein the pulse at point H corresponds to the pulse at point F determined by the point of minimum current, and for abnormal operation, wherein a minimum point is not detected during the duration of a pulse A, for example due to an excessive load on the motor, the pulse at point H then corresponding to the pulse A. Control may be made dependent on detection of the image voltage of the winding  current and cut-off of the latter, in the absence of the detection of a minimum, may occur at a mo-  ment later than that determined by the divider 2.

Abstract: 1,204,875. Shuttleless loom. SOMET S.p.A. 26 Sept., 1967, No. 43815/67. Heading D1E. When a pick of welt has just been beaten up, all the wefts 5 extend from the selvedge and under a hook 9 to individual eyelets 4 on a weft selector 2. A selected weft 5' is then moved rearwardly and a hook 6 descends to engage it; the weft 5' then extends from the selvedge to the hook 9, and from there to the hook 6 and thus lies across the path of the weft inserter, which grips it and draws it into the shed. The hook 9 has a cutting edge on the side remote from the shed, so that the weft is cut as it wraps round the hook. When the pick has been completely inserted, the hook 6 rises to release the weft 5', which is then beaten up by the reed. The hook 9 rises and descends again to re-engage all the wefts, including the one that has just been inserted, the eyelet 3' having meanwhile retracted. A feeler 8 is held down by the selected weft, but rises to stop the loom if the weft breaks.

Title: Method for controlling clamping load of a threaded fastener
IPC: F16B33/04
Filed: 1970-09-15
Abstract: 1298095 Applying predetermined tension to bolts MAC LEAN-FOGG LOCK NUT CO 15 Sept 1970 [15 Sept 1969] 44055/70 Heading F2H A method of controlling the clamping force exerted against workpieces 24, 25 by a threaded fastener which initially embodies a pair of nuts 20, 22 acting against one workpiece surface and each co-acting with a bolt 23 acting in opposition against another workpiece surface comprising the steps of (a) tightening the nuts 20, 22 on the bolt 23 and against the workpiece 25 until a predetermined clamping force between the nut 20 and workpiece 25 is sensed (b) releasing the force beteween nut 20 and workpiece 25 without moving the nut 22, to transfer the load thereto with some reduction of its magnitude and (c) tightening the nut 22 against the workpiece 25 by turning it through a predetermined angular increment relative to the bolt 23. A relievable torque driving connection is obtained between nuts 22, 20 by punching opposed depressions 38 into the outer nut 20 to produce protuberances 39 frictionally engaging the inner nut 22 whereby the nut 22 can be tightened initially by a tool applied to a polygonal collar portion 27 extending from a threaded ring portion 29 of the nut 20. The predetermined clamping force is sensed and transferred when a section 32 between the collar 27 and ring 29 ruptures axially. In one embodiment, Fig. 6 the collar 27 may be removed after rupture of the section 32 but in another, Fig. 8, it is held captive by a flange portion 42 of the ring 29 with flats aligned initially with those of the collar 27. In either case the ring 49 may be ultimately tightened against the nut 22 to serve as a lock nut. The final angular increment to be turned by the nut 22 relative to the bolt 23 is so determined that the clamping force sensed is reestablished, the increment being proportional to the clamping force and inversely proportiona to the compression characteristic of the nut 22. The clamping force may be controlled to restrict the bolt tension within the safe load limit of the bolt by suitably selecting the predetermined clamping force to be sensed.

Abstract: 1,223,177. Purifying sand. BRITISH INDUSTRIAL SAND Ltd. 3 Sept., 1969 [17 Sept., 1968], No. 44197/68. Heading C1A. The purification of sand containing iron and iron compounds is effected by contacting with conc. HCl to dissolve the iron and iron compounds, the sand being freed from unreacted acid and reaction products, which are then heated to give HCl gas and a decomposition product, predominantly iron oxides, and the resulting HCl gas is converted to cone. HCl and recycled. The acid may be introduced by spraying on to the washed and dried sand in an inclined rotary leaching drum. The mixture is then washed and filtered. The acid may be recovered from the washings by spraying the washings through hot combustion gases; the product gases from this stage then pass to an absorption tower, where the rate of flow of water is controlled so as to give acid of the desired concentration to be recycled.

Abstract: 444,807. Determining the moisture in steam. DOBBIE, McINNES, & CLYDE, Ltd., and REYNOLDS, H. E., 57, Bothwell Street, Glasgow. Dec. 4, 1935, No. 33579. [Class 97 (iii)] Apparatus for determining the moisturecontent of a sample flow of steam by measuring the quantity of heat necessary to superheat the steam, comprises a conduit for the steam to be tested and means for heating the steam in the conduit, the latter being insulated to reduce heat losses. In the form shown, a core 6 carrying a coiled helix of resistance wire forming a heater 7, an inner tube 4 of insulating material, and an outer tube 3 are concentrically mounted in a hollow metal head 1 threaded at 1a so that it may be inserted in a main pipe in which the steam to be tested is flowing. When a valve 8 is suitably opened, a sample flow of steam passes to the hollow head 1 between the core 6 and inner tube 4 and also between the inner tube 4 and outer tube 3, where it forms a jacket round the heater, and from the head 1 passes through the valve 8 and pipe 9 to a condenser which enables the quantity of steam in the sample flow to be determined. The heater 7 in parallel with a voltmeter is connected through an ammeter and variable resistance to the mains or a battery. In use the resistance is varied until the electrical input to the heater 7 is sufficient to superheat the sample flow of steam. The superheating of the steam is indicated by the movement of a millivoltmeter connected to two opposed thermocouples one being in the head 1 and the other in the main pipe.

Abstract: 1,004,874. High-frequency switching systems. WESTERN ELECTRIC CO. Inc. Dec. 14, 1961 [Dec. 23, 1960], No. 44751/61. Headings H4J and H4R. In a switching unit for switching a highfrequency signal transmission on alternative channels 11 and 13 to a carrier terminal 12 and in which the switches used exhibit a capacitive- or inductive reactance which could affect the impedance matching of the system, the switch contacts are interconnected by short lengths of transmission line, 15 to 28, Fig. 1, of an impedance different to that of the transmission channel to introduce the appropriate reactance into the circuit to compensate for the reactance of the switch contacts. In addition the leakage reactance of open contacts is neutralized by the provision of similar open contacts bridging the line across the contacts, thus, for example, when contacts K1-6 and K1-8 are open the signal leaking across the capacitive reactance of the open contacts is cancelled by the signal leaking across the contacts K3-5 and K3-7 of a relay K3 similar to relay Kl but whose operating coil is not connected. To avoid switching transients the relays K1 and K2 are operated by the relay circuit of Fig. 2, the relay K2 being arranged, by having a standing current through the coil, to operate before K1 when the switching initiator S1 is operated in one direction, and to hold, via K1-9, until after K1 falls out when the switching initiator returns to the position shown, by this means it is arranged that the sequence of a switching operation is (1) standby channel 13 is connected to load 14, (2) the combination is connected in parallel with the regular channel 11, and finally (3) the regular channel and the load 14 are disconnected from the link. Further switching units may be connected via line 28, Fig. 1, Specification 973,733 is referred to.

Abstract: 1,142,993. Magnetic head. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 10 Oct., 1966 [13 Oct., 1965], No. 45184/66. Heading G5R. In a magnetic head arrangement in which separate playback 10 and recording 9 heads scan, with the playback head leading, the same track on tape 13, the head windings are interconnected and the heads are designed such that on playback the signal induced in the playback head is at least 10 times as great as the signal induced in the recording head by the same portion of tape. The recording head gap 17 is much longer than that 16 of the playback head and the number of turns on the playback coil is greater than that of the recording coil. High frequency bias current is applied to the common junction of the heads but this may be prevented from appearing across the playback head by means of a shunt capacitor. During recording any signal recorded by the playback head is erased by the bias current applied to the record head. The number of turns on the playback coil may be sufficiently large to saturate the head during recording. The heads may be separate or may form part of the same structure, Fig. 3. The playback head width may be less than that of the recording head. Where the arrangement is used for frequency modulation video recording on oblique tracks on a tape, the heads are spaced by the distance occupied by one or more complete lines. Where the video information is interlaced the heads are preferably spaced by the distance corresponding to a small whole number of frames plus, where the whole number is odd, a half line of video information.
