Title: A process for the manufacture of hydrocarbon distillates
IPC: C10G7/00
Filed: 1934-10-24
Abstract: Hydrocarbon oils are fractionated sharply by fractional condensation and/or distillation so as to obtain one or more fractions boiling entirely above 70 DEG  C. and of such purity as to contain no components of the next lower or higher boiling fraction.  The sharp fractionation is obtained by increasing the reflux ratio to the fractionating column and by providing additional heating of the column, i.e. by drawing off fractions from intermediate levels in the column and heating them and returning them to the column at the same level.  Several columns may be used in series the residue from one column being drawn off, heated in a pipe still and introduced into the following column. The fractions thus prepared are stated to have end-points which do not overlap when determined by the A.S.T.M. method.  The following fractions can be prepared--Light gasoline (40--100 DEG  C.); light gasoline (110--135 DEG ) heavy gasoline (140--165 DEG ); light kerosene (168--190 DEG ); heavy kerosene (200--250 DEG ); gas oil (255--300 DEG ).  If products of different ranges are required two of the above fractions may be mixed together in the required proportions.

Title: Improvements in or relating to the speed control of electric motors
IPC: B65H23/195
Filed: 1950-12-18
Abstract: 676,505. Control of A.C. motors. IGRANIC ELECTRIC CO., Ltd. Dec. 18, 1950. [Feb. 18, 1950] No. 30766/50. Class 38 (iii). [Also in Group XXXV] A control system for an induction motor having a primary winding for substantially constant excitation and a second primary winding for variable excitation comprises means to subject said second primary winding to potentials differing in phase and amplitude with respect to the potential impressed upon said first primary winding, said means comprising a capacitor and a gaseous electron discharge tube in series with said second winding and in parallel relation with one another, a transformer comprising an input coil to be subjected to constant alternating current excitation, an output coil, and means for varying the magnetic coupling between said coils of said transformer, and a phase-shift network in circuit with the control grid of said discharge tube for subjecting the same to an alternating control potential varying in phase relation the control grid potential with respect to the anode of said tube in accordance with the degree of magnetic coupling between said coils of said transformer. As shown, an induction motor 12 drives a bobbin 10 upon which thread, passing at a constant let-off speed from spool 14, is wound. One of the motor stator windings 12b is connected in series with a phase-shifting capacitor 22 shunted by a discharge valve 23 the grid control of which determines the relative phase displacement of the voltages applied to the two stator windings of the motor, and therefore the speed. An adjustable resistor 27 together with its connections with auto-transformer 25 constitutes one side of a phase-shift network for the control grid of the valve 23, whilst a saturable reactor 28 is comprised in the other side of the phase-shift network. A loop is formed in the thread by means of a tension arm 18 of a control device 19, and, in the position depicted, minimum coupling exists between coils 35, 32. Consequently a reactor saturating winding 31 which is supplied from winding 32 through rectifier 33 has minimum energization so that the control voltage of the valve 23 is so phased that the valve is cut off and the motor runs at maximum speed. When the length of the loop decreases the coupling between coils 32, 35, increases and the conductivity of the valve 23 is increased to reduce the speed of the motor. A filter capacitor 34 maintains current in saturating winding 31 during the half cycles when rectifier 33 is non-conductive. Specification 674,744, is referred to.

Title: Improvements in or relating to apparatus for maintaining artificial respiration
IPC: A61M16/00
Filed: 1956-10-12
Abstract: 842,890. Respiratory appliances. MANLEY, R. E.W. Jan. 10 1958 [Oct. 12,1956], No.31104/56. Class 81(2). In artificial respiration apparatus the gas is supplied to the patient through a bellows or similar arrangement, the bellows co-operating with means for controlling the flow of gas to and from the bellows and having a jockey weight for applying an adjustable moment to the bellows in order to determine the pressure supplied to the patient. The bellows 12, fig. 2 is mounted between the top plate 11a of a casing 11 and a rectangular frame 14 mounted on a horizontal pivot 15. The frame 14 carries an arcuate arm at its free end and this has a fixed stop 16 and adjustable stop 18 which co-operate with toggle mechanism for actuating control valves, the effect being such that a lever 24, fig. 4, is raised and lowered at the upper and lower limits of the bellows movement. The lever 24 is secured to a rod 22 which is made to snap from one extreme position to the other by a spring 26. Abutments 30a, 30b, attached to the rod 22 consequently drive a lever 31 connected to a valve plunger 29 which, in its righthand position, connects ports 21a, 21b to allow gas to pass from the bellows to the face mask and, in its left-hand position, connects ports 21c, 21d, to allow gas to pass from the mask to atmosphere through a pipe 32. The gas supply is led into the bellows and inflates it until the trip mechanism is actuated, whereupon the gas supply is cut off by a valve not shown and communication between ports 21a, 21b allows the bellows to collapse, under the action of adjustable weight 33, and pass the gas into the lungs. On complete collapse of the bellows the trip is again actuated and the lungs are emptied through ports 21c, 21d while the bellows is again being inflated. Adjustment of the setting of the weight 33 determines the pressure at which the gas is maintained as it passes into the lungs.
