IPC: G04D3/08
Filed: 1943-12-21
Abstract: 580,749. Drying-apparatus. DRUMMOND, Ltd., C. T., DRUMMOND, C. T., and. ORCHARD, A. L. Dec. 21, 1943, No. 21382. [Class 34 (ii)] [Also in Groups VIII, XVIII and XXIII] Apparatus for cleaning or washing articles, for example watch 'parts, dishes &c. clothes and metal or other articles, or for dry cleaning, comprises a container 1 with a cover 2 having fixed to it a sleeve. 3 to the lower end of which is secured a cover 4 adapted to hold attached to it by bayonet joint a cage 5, to the bottom of which is fixed a sleeve 9 secured also by strengthening ribs 10 soldered on. A collar 20 is secured to the sleeve 9 on which rests a removable disk 21 of wire mesh strengthened at the inner and outer edges by metal rims. The bottom of the cage 5 has apertures, covered with wire mesh and the cover 4 has apertures not so covered. In the sleeve 9 works a shaft 11 having at the lower end a disk cf four blades 12, and at the top an enlargement 13 with a square hole 14 to engage and be driven by the squared end of a shaft 15 located in the sleeve 3 by soldered collars 16 and having a prolongation 18 for engagement by a coiled spring flexible shaft 19 connecting it to a driving motor. A collar 22 fits snugly on the enlargement 13 and carries a pair of impeller blades 23 to stir the flowing liquid. A band of corrugated metal 24 is mounted in the container 1 to surround the cage. The articles being placed ir, the cage and liquid being filled in to a little distance above the cage, the motor is started and the blades 12 rotate to drive upwards and outwards the liquid which is then guided by the corrugations 24 without rotating to return over the cage and through the top, the downflow being rotated by the impeller 23. The corrugated surface 24 may be placed on the cage which may be rectangular in section instead of circular. For cleaning large and small parts, for example, of a watch, an inner cage may be placed on the shaft enlargement 13 instead of the impeller, consisting of a wire mesh container 25, Fig. 4, on an apertured sheet metal cover 26 having an attached central sleeve 29 with a narrower top 28 to fit over the enlargement 13 and a cover 30 of wire mesh with an inner rim 31 and outer flange 32. The inner cage rotates with shaft and causes rotation of the descending liquid. Specification 556,493, [Group VIII], is referred to. For drying the articles the liquid is removed and operation will cause a flow of air through the cage which air may be treated by an electric heater placed below the container.

Filed: 1936-08-01
Abstract: 478,011. Making tubes. WELLMAN SEAVER ROLLING MILL CO., Ltd., and McLAY, G. S. Aug. 1, 1936, No. 21395. [Class 83 (iv)] Rolling cupping.-In making closed-ended tubes by pushing a thick cup-shaped billet through a series of ring dies or roll passes as described in Specification 300,288, [Class 83 (iv)], a number of radial mandrels 1 are used in turn to push a billet 26 through a series of ring dies in a holder 14. The pushing is done by reciprocating the mandrel carrier along slides 5 by means of a connecting, rod 8 and crank pin 9, while the dies 13 are also reciprocated over the billet and back again by a connecting rod 16 and crank pin 17 the back movement also acting to strip the billet off its mandrel by a stripper plate in front of the dies, the stripper being split and spring pressed to allow the billet to pass through during the drawing stroke. The mandrel carrier is locked against rotation during working, e.g. by a fork (29 not shown) operated by hand, solenoid, pneumatic, or hydraulic mechanism moved in to hold firmly the mandrel diametrically opposite to the pushing mandrel. A mandrel guide ring 25 is fixed on the die carrier 14. The reciprocating cranks of both mandrel and die are geared together and driven by an electric motor 21 to give slow drawing speed and quick return stripping. In a modification the dies only, are reciprocated over the billet and each mandrel is secured to a holder bar, stepped to correspond to the sizes of the succeeding die rings or roll passes.

Filed: 1972-05-09
Abstract: 1339683 Gyro compasses TOKYO KEIKI KK 9 May 1972 [15 May 1971] 21613/72 Heading G1C Gyro apparatus includes at least two gyro compasses 1a, 1b coupled to respective synchro control transmitters 2a, 2b to produce azimuth output signals, and a mean value calculator 12 to provide a mean value of said azimuth signals for an indicator 14a/14b. A difference circuit 17 provides a signal representing the difference between the azimuth signals for a warning unit F which compares the difference with a standard signal and actuates an alarm lamp 23 and buzzer 24 if the difference exceeds a predetermined value. The faulty gyro compass can then be switched out. Servo loops A, B for the gyro compasses 1a, 1b convert the azimuth signals from the synchro control transmitters 2 into mechanical signals for the mean value calculator 12 and the synchro control transmitters 15, 16 which provide the inputs to the difference circuit 17, the servo loops at the same time applying speed and heading corrections to the signals. The synchro control transmitters 2a, 2b rotate one revolution and nine revolutions respectively for one revolution of the compass azimuth card. The mean value calculator 12 drives two torque synchro transmitters 13a, 13b which produce signals respectively equal to one and thirty-six times the calculator 12 output. A three-way switch SW 1  connects the gyro compass synchro control transmitters to their respective servo loops A, B; connects both servo loops to the transmitters of compass 1a; or connects both servo loops to the transmitters of the compass 1b. Systems are described using three and four gyro compasses.

Filed: 1953-08-11
Abstract: 746,191. Electric indicating systems. NATIONAAL LUCHTVAARTLABORATORIUM. Aug. 11, 1953 [Aug. 12, 1952], No. 22174/53. Class 40(1) For measuring rotational speed and/or for totalizing revolutions, an inductance included in a constant current high frequency oscillator also forms part of a second oscillatory circuit including a second inductance whose impedance is varied periodically and proportionally to the speed to be measured. The H.F. current in the oscillatory circuit is thereby amplitude modulated and the H.F. voltage across one of the inductances is rectified to operate a frequency meter at the modulation frequency. As disclosed in Specification 746,190, the self-inductance of a coil 2 mounted on an open ferro-magnetic core is varied periodically by a rotating shaft at a frequency proportional to a fluid-flow to be measured. The coil 2 forms part of an oscillatory circuit 2, 3, 5, 6, 7, the coil 5 of which is connected in the anode circuit of a constant-frequency constant-amplitude electron-coupled oscillator 4, the H.F. current in this circuit being thus amplitudemodulated at the shaft speed. The H.F. voltage across coil 5 is rectified at 13, the L.F. modulation output being fed at 14, 15 to a frequency meter to indicate shaft speed and fluid flow. For measuring the weight of fluid flow, e.g., in the case of aircraft, correction for temperature changes of the liquid may be effected by a temperature sensitive resistor 16 connected into the frequency measuring circuit at 21, 22 over the cable 8, connecting the coils 2 and 5 by means of H.F. filters 17-18, 19, 20. The fre-, quency meter may operate a counter to totalize the shaft revolutions..
