Title: Process for the transportation of flour and apparatus for carrying out this process
IPC: B65G53/00
Filed: 1950-04-21
Abstract: 669,885. Air conveyers. BRUNET, J. M. A. April 21, 1950. [April 22, 1949; Nov. 17, 1949] No. 9837/50. Class 78 (i). [Also in Group XXVIII] In a process for the pneumatic transportation of flour between three stages of milling, the same pumping means B serves simultaneously to suck a first air stream transporting the flour from the first stage to the second stage, and to blow a second air stream transporting the flour from the second stage to the third. Fig. 1. Flour ground a,t first grinder A is conveyed to second' grinder D by air on the suction side of pump B, being filtered therefrom by filter C, and is then conveyed to third grinder F by air on the compression side of said pump, being filtered therefrom by filter E. Figs. 2 and 3. Filter C. Flour laden air arrives by pipe 6 and passes into container 11 and, after passing around baffle 7 and through gap 8 therein, is filtered by bags 2 and passes into chamber 9 and out through pipes 22 and 23 to discharge pipe 10. The bags 2 are disturbed or vibrated regularly by dilation of their respective impermeable membranes 13, air passing thereto from the atmosphere whenever hole 12 in rotating disc 15 coincides with a mouth of a membrane. Rotor 5 discharges the material. Fig. 4. The connection between membrane 13 and disc 15 is sealed by sleeve 12, which is formed with hole 14 for allowing the periodic escape to chamber 9 of the air which has entered the membrane through hole 12. Figs. 6 and 7. Modifications of Fig. 4. The periodic escape of air from membrane 13 takes place through passages 31, 29, 30, the passage 31 being formed in disc 15a. Fig. 5. Filter E. The same as Fig. 2, except that an extra chamber 24 is added, and is connected at 25 to the compression side of the pump, so that this compressed air causes the membranes to dilate as before.

Abstract: 735,917. Impedance measuring bridges. WAYNE KERR LABORATORIES, Ltd., and CALVERT, R. April 2, 1954 [April 13, 1953], No. 9972/53. Class 37. An A.C. bridge for measuring low impedances comprises a pair of series secondary windings of an excitation transformer constituting the first and second bridge ratio arms, a standard impedance forming the third arm, and a pair of series fixed impedances forming the fourth arm; each of the latter impedances being greater than the impedance to be measured, which is connected between the junction of the first and second arms and that of the fixed impedances; an unbalance detector being transformer coupled between the junction of the first and second arms and that of the third and fourth arms. Where Z1, Z2 are the fixed impedance magnitudes, Zs the magnitude of the standard impedance and Ts, Tu are respectively the product of the turns in the ratio arm and the detector transformer windings associated with the standard impedance, and the product of the turns of the similar windings associated with the unknown impedance; the unknown impedance Z (including its connection impedance) is given by In Fig. 1 an A.C. energized input transformer 9 has series secondary windings 11, 12 respectively joined over series impedances 17, 18 (which may be resistive) and adjustable standard complex impedance 19 to one end of the primary of a current transformer 15 energizing an unbalance detector (not shown). The free end of the transformer primary is connected direct over line 13 to the junction of the windings 11, 12 (which as ratio arms may by adjustably tapped or incorporate adjustable A.C. potentiometers) while the unknown impedance 20 is connected between line 13 and the junction of impedances 17, 18. The standard impedance is separately adjustable for reactance and resistance to balance the bridge. For measuring an unknown resistance, the fixed and standard impedances are resistive (Fig. 2, not shown). In a modification (Fig. 3) the ratio arm windings 11, 12 are respectively fixed and variably tapped and the impedances 17, 18 are resistive while the detector transformer 15 has two series input windings 40, 41 whose junction is connected over line 13 to the junction of windings 11, 12. A variable resistive standard 43 is connected between the free end of winding 12 and the junction of winding 40 and resistance 17 while an adjustable standard condenser is connectable by switch 46 between the junction of winding 12 and resistance 43 and a variable tap on either winding 40 or winding 41 accordingly as the unknown impedance 42 is capacitative or inductive.

Title: Manual sweeping type copying machine
Inventor: IYAMA HIROYUKI
IPC: G03G15/22
Filed: 1986-01-07
Abstract: PURPOSE:To synchronize sweep speed with paper feed speed and to stabilize the sweep direction by operating an image sensor and a printer synchronously with the read signal of a scale generated synchronously with the sweep of a read section. CONSTITUTION:The signal of a read section 2 and a printer section 3 consisting mainly of line type image sensors such as CCD is transmitted/received by using a cable and an infrared ray. The read section 2 is swept straightly forward and a straight line guide 4 is provided, which prevents a character or a graph from being deviated from a desired range. The read section 2 reads a scale 5 by optical or mechanical method in addition to the reading to feed the paper of the printer 3 synchronously with the signal. Thus, the sweep speed of the read section 2 and the paper feed speed of the printer 3 are coincident and a copy corresponding one by one to the original is obtained.

Filed: 1997-01-08
Abstract: PROBLEM TO BE SOLVED: To provide a device, which eliminates troublesome operations of and eligibly prevents miss-inputting of identification codes at the time of inputting organism identification codes to a prescribed signal processor. SOLUTION: This device compares an electrocardiographic induction waveform precedently memorized to an organism information waveform identification code memory system 42 by an organism information waveform identity determination means 46 and an electrocardiographic induction waveform measured by an organism information waveform measurement device 40. When mutual identity of the above two are affirmed, an ID code, corresponding to an electrocardiographic induction waveform having the same identity with the electrocardiographic waveform measured by the organism information waveform measurement device 40, is determined as the ID code of a prescribed organism and is input to this device.  Therefore, the ID code is input to a prescribed signal processor automatically, thus troublesome operation of inputting the ID code to the signal processor becomes unnecessary and, at the same time, miss inputting the ID code is eligibly prevented.
