Title: Method and rotary apparatus for generating an air current
IPC: F04D17/16
Filed: 1961-04-14
Abstract: 988,854. Centrifugal fans. JUNKER & RUH A.G. April 14, 1961 [June 2, 1960], No. 13437/61. Heading F1C. [Also in Division H2] An air current is produced by leading the air to an impulse-exchanging rotor in the form of a fibrous unit which separates intake and pressure chambers, the air being deflected, on flowing radially through the unit, in such a manner that the mechanical energy of rotation of the unit is connected into flow energy of the air. Fig. 3 shows a fan in which the impeller comprises a ring 32 of felt or other fibrous material in which the fibres are preferably arranged along the peripheral direction whereby the air passing through the fibrous material is acted on by frictional forces only. In passing through the volute 33, the air cools the driving motor 36. A rotary deflector 34 may be provided to direct the air flow around the motor. In addition, a stationary deflector (not shown) extends from the cut-off of the volute towards the motor. The air is filtered by the fibrous material, which may be a plastics material so as to receive an electrostatic charge which enhances the filtering. The elimination of fan blades reduces noise, and the flow is stable at all rates of flow. The impeller may be provided with a humidifying device, the large area of contact between the air and the fibrous material allowing the air to be readily humidified or evaporatively cooled. The fibrous material may be in the form of a disc instead of a ring. In the embodiment shown in Fig. 5, the fibrous disc 63 is carried by an impeller including a conical portion 63a serving as the rotating inner wall of an annular diffuser through which the air is discharged in an axial direction. Some of the air returns from the diffuser in the direction of the arrows 72 to cool the driving motor 71, re-entering the impeller through by-pass openings 69. Heating filaments or condenser coils may be introduced into the exhaust cross-section without producing noise by interference with the air flow. In a further embodiment, Fig. 8, the impeller comprises three rings 107 of fibrous material, resting loosely within a reticulated container 102 and readily removable for cleaning purposes. The container 102 is carried by the external rotor 101 of a driving motor, the stationary shaft 103 of the motor being supported by springs 104 and rubber bushes 105.

Abstract: 588,440. Substation equipment. NEWTON, E. P. (Ipsophon Patentges. Akt.-Ges.). July 14, 1944, No. 13506. [Class 40 (iv)] Phonographic apparatus which is set in operation by ringing current when the substation is unattended delivers a general message followed by a series of numbers in spoken form, instead of a series of buzzer signals as hitherto, as a guide to the calling party in sending tone signals for controlling further operation of the apparatus. As described, a steel tape record is employed and a number of cam discs NKS1, 2 ... driven concurrently with the record, control contacts NK11, 12 ... After each number is transmitted, contacts NK11 are closed to energize relay VU, which transfers the incoming line from the pick-up head SPK to relay JR. Before leaving the substation, the subscriber operates a key such as 47 or 48, so that after a particular number, relay JP energizes over corresponding cam contacts and prepares a circuit for relay AN, which is completed if the calling party sends a tone signal to operate relay JR at the proper time.

Title: Circuit arrangements for controlling three-phase asynchronous motors
IPC: H02P3/18
Filed: 1968-03-22
Abstract: 1,200,250. Automatic control of speed. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. March 22, 1968 [March 25, 1967], No.13971/68. Heading G3R. [Also in Division H2] In a system in which a three phase asynchronous motor is controlled for both driving and D.C. braking by controlled rectifiers (thyristors), during driving one phase U at least is energized only through one, half wave, rectifier. This enables an immediate change from driving to braking, whereas in prior art systems braking may be delayed up to 270 degrees to avoid short circuit between supply phases. As shown, for driving, phases V, W are energized through back to back thyristors 3---6, and U is energized through 1 only; for braking, D.C. is applied to U only from all supply phases RST through thyristors 1, 7, 8. Triggering is controlled by a logic circuit Fig. 5 (not shown) in which the polarity of the difference between a tachogenerator voltage and a reference determines whether driving or braking thyristors are fired and the magnitude of the difference selects a point at which a sawtooth waveform (derived from the supply RST) is gated to triggering transformers and thus controls the firing angle. For small motors one of the braking thyristors may be omitted, and/or two driving thyristors 4 and 6, so that each phase is energized for driving with only half wave A. C. In Fig.6 (not shown) the windings are delta connected, one terminal is connected directly to the supply R, another to S through one driving and one braking thyristor and the other to T through a pair of back to back driving thyristors. This energizing arrangement may also be applied to a star connected motor.

Title: Process for the purification of the yellow oxidation ferment
IPC: C12P13/00
Filed: 1937-05-20
Abstract: The yellow oxidation enzyme present in yeast and obtained in solution in the known manner from Lebedev juice is purified by adsorption from the crude solution with adsorbents such as aluminium or iron hydroxides, aluminium silicates such as fuller's earth and bleaching earths known under the Registered Trade Marks "Frankonit" and "Floridin," and the ortho-aluminium hydroxide of Willstatter and Krant.  The enzyme is separated from the adsorbate by elutriation with weakly alkaline solutions such as ammonia, preferably in the presence of phosphates such as diammonium phosphate.  The enzyme may be salted out with ammonium sulphate.  In an example, a dialysed solution obtained from Lebedev juice is treated with a little diammonium phosphate, and a suspension of aluminium hydroxide is added; the adsorbate is elutriated with dilute aqueous ammoniacal diammonium phosphate and the solution dialysed, the process being repeated.  The enzyme is salted out with ammonium sulphate at pH 5,2 (acetic acid) and the precipitate is dissolved in water and dialysed. The enzyme may be completely purified by repeating the adsorption, elutriation and dialysis.
Patent GB-879661-A (GB)
Title: Improvements in or relating to low-frequency amplifiers
IPC: H03G7/00
Filed: 1958-05-02
Abstract: 879,661. Automatic volume control. PHILIPS ELECTRICAL INDUSTRIES Ltd. May 2, 1958 [May 4, 1957; Jan. 10, 1958], No. 14084/58. Class 40 (4). In an audio-frequency amplifier a manual volume control is coupled to a contrast variation control so that setting to low output introduces volume compression. Input signals applied to terminals 1 are fed from a continuously variable potentiometer 3<SP>1</SP> to an amplifier 5, the output of which is applied to a bridge consisting of current-dependent resistors 8, 9, such as incandescent lamps, and a potentiometer device 21, 21<SP>1</SP>, 22, 24, 24<SP>1</SP>, 25. A loud-speaker 13 is connected across the bridge diagonal. The resistors 8, 9 each vary between about 200 ohms (no signal) and 1200 ohms (strong signal) whereas the upper portions of the potentiometers 21, 24 have values of about 150 ohms. If with the switches 22, 25 in the positions shown the sliding contacts ganged with that of 3<SP>1</SP> are moved to the upper ends of 21, 24 the bridge is approximately balanced for small-amplitude signals but is unbalanced for large-amplitude signals, so that volume expansion occurs. As the sliding contacts are moved downwards the degree of volume expansion becomes progressively smaller and is zero when the sliding contacts of 21, 24 reach the fixed tappings. On further downward movement the coupling devices 23, 26 actuate the switches 22, 25 so that the lower portions of the potentiometers 21, 24, each of from 2000 to 4000 ohms, are included in the bridge, together with the fixed resistors 21<SP>1</SP>, 24<SP>1</SP> each of 1500 ohms. The bridge circuit is thus greatly unbalanced for small signals and approaches balance for increasing signal strength resulting in volume compression as the sliding contacts are moved downwards. In a simpler arrangement (Fig. 1, not shown) the continuously variable potentiomer 3<SP>1</SP> is replaced by one having two positions only, and the devices 21, 21<SP>1</SP>, 22, 24, 24<SP>1</SP>, 25 by fixed resistors. Operation of the potentiometer to the high volume position then short-circuits the resistors 8, 9 to cut out the volume compression which takes place in the low-volume position.
