Filed: 1920-10-01
Abstract: 151,937. Haveloose, M. d'. Oct. 1, 1919, [Convention date]. Copying.-The copying point of an apparatus for roughing out copies of statues &c. is adjusted by means of a double pantographic mounting on a fixed support, the two parts of the mounting determining respectively the position of a particular line and the point upon it, each point of the copy being determined separately in turn. For this purpose, a primary pantograph m, n is supported on a column f and carries on one arm n a tracer u mounted in a tubular holder z and attached at 11 to one link of a secondary pantograph. The holder z has a spherical part s forming a universal mounting. By means of a slot y and lugs w the tracer can be locked to or freed from the lower link of the pantograph. A stop collar 6 is adjusted in contact with the lug 11 after the tracer point has been placed on the required point of the model, thus locking the secondary pantograph, which is transferred to the other arm m of the primary pantograph, and the latter then transported to a second column f provided for the block to be worked. The lugs w are now freed and the point of the tracer is caused to penetrate into the block until the stop collar 6 meets the end of the tubular holder z, for which purpose the tracer may be used as a drill, driven by hand or otherwise.

[Class 13] [See also Group XXIX] In a device for giving an audible indication when air is passing through a tyreinflating apparatus, the air enters a chamber 4 through an opening 6, and passes through a filter 7 and a bore 17 so as to lift a ball 34 and spring-pressed plunger 22 slidable in a cylindrical member 14. The plunger 22 has flattened faces on its periphery to allow the air to pass through the tube 14 to an outlet 33 connected by a pipe to the nozzle. When the plunger 22 is raised, the air passing through causes the ball 34 to be reciprocated between the plunger 22 and its seat 19 so as to produce a tapping sound. An outer casing 13 forms a sound-amplifying chamber which deflects the sound-waves against a dome-shaped member 26 and thus produces a ringing sound. An outlet 8 closed by a cock is provided at the bottom of the chamber 4 for removing matter filtered from the air.

Title: Arrangement for and method of determining the phase shift angle between two electrical alternating signals of the same frequency
IPC: G01R25/08
Filed: 1975-07-07
Abstract: 1507323 Measuring phase difference  LICENTIA PATENT VERWALTUNGS GmbH  7 July 1975 [6 July 1974] 28546/75 Heading G1U In phase difference measurement, the reference signal phase is displaced by a predetermined amount if the difference falls within a predetermined range around zero, to avoid 180 degrees ambiguity in an averaged measurement, owing to the discontinuity at 360 degrees. In a direction finding system the reference signal is derived from an oscillator 4 via divider 5, and change-over switch 7. The pulse generator 3  provides pulses whose width indicates the phase difference. These pulses open gate 8 and counter 10 counts clock pulses from the generator 4. The system is controlled by unit 9 comprising a four stage counter incremental at every cycle of the input signal 1. At state "8", output 12 enables gate 8 to start measurement. At the end of state "8" output 13 goes high, enabling gate 15. If the measured phase difference lies in the range Œ45 degrees trigger 16 resets the counter 9 to "8", operates switch 7 to supply the second input of generator 3 with a 180 degree shifted reference signal and passes a signal to counter 10 to adjust the measured values accordingly. If no output is provided by gate 15, the measurement proceeds and eight values are stored in counter 10 (up to state "15"). During the other states of counter 9, gate 8 is blocked, and at state "4", the counter 10 has its oldest eight values cleared. After sixteen measurements, the counter stored values are averaged and output at 19.

Abstract: 1310175 Carbonization FARBWERKE HOECHST AG 12 June 1970 [12 June 1969] 28646/70 Heading C5E [Also in Division C1] A carbonaceous material has a specific resistance of at least 10<SP>7</SP> ohm cm. and comprises from 65 to 100% by weight of carbon and is amorphous to X-rays. It may be made by dehydrogenating a suitable hydrocarbon material. Such hydrocarbons are defined generally as having a non-planar structure, containing at least two non-aromatic rings at least one carbon atom being common to the rings. The materials are exemplified by adamantane, triamantane, tetrahydrodicyclopentadiene, camphene or pinene. The pyrolysis or carbonization may be performed in the presence of a catalyst, e.g. Pt, Ni or Pd, at a temperature of 150‹ C. at atmos. pressure. If desired the organic hydrocarbon may be dissolved in a solvent maintained liquid at the reaction temperature, e.g. chloro- or bromo-naphthalene. The product may be annealed under sub-atmospheric pressure at a temperature of up to 250‹ C. In an alternative embodiment the hydrocarbon may be dehydrogenated at elevated pressure and a temperature exceeding 150‹ C., e.g. 800‹ C. and up to 60 kilobars. A catalyst which preferably becomes fluid under the conditions used may also be utilized in this embodiment. The catalyst may be Ge, Sn, Mg, Ga, In, Pt, Mi or Fe, and the catalyst may dissolve out of the product obtained. The carbonization may be achieved using a luminous discharge in a hydrocarbon atmosphere, or by bombarding the hydrocarbon with electrons or ion, or by decomposing the hydrocarbon at a heated surface or exploding a gaseous mix of the hydrocarbon and a gas which has a greater affinity for hydrogen.

Abstract: 929,267. Turning threads. K. BURGSMULLER. Sept. 4, 1959 [Sept. 5, 1958], No. 28649/58. Class 83 (3). A method and apparatus for " whirling " a thread or a plain polygon on a workpiece comprises driving the workpiece about an axis in one direction at a speed suitable for normal lathe operations and displacing the workpiece axially while subjecting it to the intermittent cutting action of a tool rotating eccentrically about said workpiece axis in the opposite direction. In a first arrangement a thread-cutting tool 27, Figs. 2 and 3, is arranged within a cylindrical holder 25a which is rotated about an eccentric axis 22 relatively to a workpiece 14 but in the opposite direction. The tool is moved axially relative to the work by a lead screw and the differential between the work speed and tool speed determines whether one or more " start " threads are cut. Plain polygons may be cut by the same arrangement. In another arrangement a chuck 29, Fig. 4, drives a workpiece 28 in the opposite direction to a rotary tool-head 40 carrying one or more cutting tools 39. The chuck spindle is provided with a lead screw 31 for moving the work axially and the lathe spindle 32 is connected by gearing to the rotary tool-head. The latter is adjustable to the inclination of the threads. Examples are given of relative rotational speeds between the work and tool-holder and also suitable cutting speeds.

Abstract: 682,740. Calculating-apparatus. HUBER, F. J. A. Nov. 23, 1950 [Nov. 29, 1949], No. 28702/50. Class 106 (i). A logarithmic device for evaluating the true airspeed of an aircraft from the indicated airspeed, temperature and pressure altitude takes account of impact temperature rise at the thermometer. An evaluation is made with two settings, and Mach number and temperature rise are also shown. A circular form of the device comprises a pair of concentrically-pivoted discs 20 and 21 with a transparent radial cursor 23. Continguous logarithmic pressure scales 33 and 45 are marked off on the two discs, the former for setting the indicated airspeed (impact pressure) and the latter the indicated altitude (static pressure). The ratio of these two pressures is the Mach number and is shown directly on a scale 32 on the larger disc 20 at a reference mark 41 on a projecting portion 40 of the smaller disc, after adjusting the two discs to bring the instrument readings of airspeed and altitude on the scales 33 and 45 into coincidence. For a given Mach number the true airspeed depends only on temperature. A temperature scale 43 is therefore provided on the smaller disc and the cursor 23 is set to this scale to show the true airspeed on a scale 30 on the larger disc. To correct for temperature rise at the thermometer, the indicated temperature indicia of the scale 43 comprise a system of isothermal curves on a transparent panel provided on the smaller disc, and a reference curve 35 is marked on the larger disc to intersect the indicia 43 variably according to Mach number, the temperature scale being read along the curve 35 at its intersection with the indicia 43. The curve 35 is, for convenience, a spiral and the scales 43 and 30 are marked off accordingly. A scale 31 shows the temperature rise at the setting of the cursor. The Specification quotes formulµ for laying off the various scales and shows how they are developed from standard formulµ relating the factors involved. The scales can be computed for either subsonic or supersonic speed ranges only, or for both ranges. In the latter case the pitot tube position error, which would normally be taken account of in the subsonic range, can be omitted in order to maintain continuity.

Abstract: 1354770 Moving domain devices WESTERN ELECTRIC CO Inc 18 June 1971 [24 June 1970] 28778/71 Heading H3B In a moving magnetic domain device, Fig. 1, domains representing '0' and '1' bits are propagated in two distinct channels separated by a magnetically soft material or by a groove in the sheet containing the domains. The sheet 11 has two circulating paths defined by a loop of permalloy 12, and two serpentine conductors 14, 15 are provided on respective faces of the sheet to move domains such as D along the paths. The domains shown at D are assigned the bit '0', while those lying on the outer edge of the loop signify '1'; only the latter are detected by a reading device for supply to a utilization circuit 24, the absence of a '1' signifying a '0' in the usual manner. The domains are maintained stable in size by a bias field set up by source 25. Domains are not created and destroyed, but a '0' domain may be converted into a '1' by pulsing a loop conductor such as that shown at 20 in Fig. 2, to displace it across the permalloy loop 12; by reversing the current a '1' may be drawn across the loop to become a '0'. Such pulses are derived from source 21, Fig. 1, under control of synchronizing circuitry 26. The dimensions of the permalloy strip govern the ease with which domains are displaced across it, and the width is chosen to be about 0À7 times the domain diameter in regions where displacement across it may be desired. Elsewhere the width is 0À5  times the diameter except around the reading device where a factor of 0À2 is used to separate the '0' and '1' domains widely. The reading device may be a simple conductor loop or Hall probe, or optical reading by Faraday or Kerr effect may be used.
