Title: Electrical distant indicating apparatus
IPC: G08C19/24
Filed: 1929-05-28
Abstract: 315,261. Schneider et Cie. July 10, 1928, [Convention date]. Addition to 245,761. Drawings to Specification. Order apparatus.-In an electric signalling system of the type described in the parent Specification wherein, in accordance with the setting of the brushes of a transmitting switch driven by a synchronous motor, impulses are generated at varying instants in the time period of rotation to illuminate at the receiver a gloss discharge lamp co-operating with a synchronous motor to produce a corresponding indication by means of a luminous position, the synchronous motors are of the type described in Specification 280,858, [Class 35, Dynamo.electric generators &c.], and a hand-operated brake is provided for the motor at the transmitter in order to compensate variations on the resisting couple developed by the brushes. The brake is adjusted until a luminous pointer of an auxiliary receiver provided at the transmitter is brought into coincidence with a counter pointer which is mechanically actuated by the transmitter control handle. To facilitate correction of phase displacement between the transmitter and receiver, a special signal transmitted by an additional fixed brush is adapted to operate the discharge lamp at a point corresponding to the position of the fixed reference brush and an adjustable brake is provided at the receiver to effect correction. In this arrangament, a two-way switch is provided at the receiver to switch the discharge lamp from the normal signalling circuit to the circuit of the additional brush when a test of synchronism is made. Alternatively, a further discharge lamp may be provided at the receiver for indicating the reference signals. When signalling is effected by wireless high frequency, impulses of predetermined duration may be transmitted to produce circular arcs of illumination at the receiver, counter pointers adjustable by hand having a corresponding breadth. This permits the direct use of the modulation frequency at the receiver. Provision also is made for the transmission of fine and coarse indications by geared adjustable brushes co-operating with separate rotating switches, and additional manual adjustment is provided in the gearing of the coarse transmitter to compensate errors due to brush wear.

Title: Fractional separation of crude hydrocarbon oil
IPC: C10G7/00
Filed: 1936-06-18
Abstract: <PICT:0476610/III/1> Crude hydrocarbon oils are separated into fractions by fractional distillation by adding to the crude oil in succession a number of carrier substances of known boiling point in order of magnitude of their boiling points, beginning with the lowest boiling-point substance, the series of carrier substances being selected so that each has a boiling point below the temperature at which the fraction to be collected would distil without the presence of the carrier substance and a vapour pressure at the desired distillation temperature sufficient to bring the total vapour pressure at that temperature of carrier substance and fraction to be collected up to the pressure in the still, distilling the mixture after the addition of each carrier and collecting the distillate until the boiling point of the carrier is reached and only the carrier comes over; whereafter the next carrier of the series is added and the procedure repeated.  The carriers can be added in the vapour or liquid state and the distillation can be carried out under reduced pressure.  The collected fractions can be separated from the carriers carried over therewith (1) mechanically when the fraction and carriers are immiscible, (2) by distillation when miscible.  In an example the carriers used successively are hexane, decane, naphthalene, bromonaphthalene, and benzophenone.  A still 1 provided with a stirrer 2 and a heating coil 3 is filled with the oil to be distilled.  After air has been removed hexane from a container 5a is heated to boiling point in a coil 7 and then run into the still.  The still is then heated until the lowest fraction and the carrier distil over, the distillate being condensed in the cooler 9 and collected in a receiver 10a.  The remaining carriers are then added successively from the containers 5b, c, d, e, and the corresponding distillates collected in the receivers 10b, c, d, e, respectively.

Abstract: 582,297. Regulating fluid flow. WILD & CO., Ltd., M. B., and BATTY, A. W. H. Sept. 6, 1944, No. 17050. [Class 135] A valve device particularly for regulating the rate of operation of a hydraulic mechanism is adapted to provide a restricted flow in one direction and a relatively unrestricted flow in the opposite direction. A cylindrical valve member c is provided with a relatively small port c<3> in its skirt portion c<1> co-operating with a port k communicating . with a passage i and a large port c<2> co-operating with a port j in communication with a passage h. The passage through port j is normally full open, but the passage through port k can be adjusted by rotation of the valve member c through rod g. Flow from passage h and port j to passage i and port k results in the piston member c being lifted against a spring r to allow unrestricted flow through port k, but flow in the reverse direction creates a pressure drop across ports k, c<3>, the higher pressure acting behind the piston c through a passage m from passage i. A screw plug n is also provided in the passage i to regulate the rate of flow.
