Title: Improvements in or relating to oil fractionation
IPC: B01D3/14
Filed: 1931-07-03
Abstract: <PICT:0390496/III/1> In the fractionation of oil, the oil is partly vaporized in a heater 10 and passes through a pipe 12 to a fractionating tower 13, steam, superheated in a coil 9, being supplied to two stripping sections 17, 18 by branches 15a, 15b of a pipe 15. Fractions are drawn off from these sections by pipes 20, 21 and by a pipe 23 from a pocket 22 in one of the trays 16 and conveyed to vacuum tanks 37, 38, 36 respectively, a liquid loop 46 and a cooler 39 being provided in each of the pipes.  Steam and vapour are conducted by a pipe 24 to a condenser 26 in which, at the pressure maintained in the apparatus, viz. 26 to 28 millimetres, the oil is condensed and the steam passes by a pipe 28 to a barometric condenser 29 supplied with water at 58 and connected to a steam jet vacuum pump 35.  Condensed oil collects in a well 27 of the condenser and is prevented from being carried into the pipe 28 by baffles 32.  From the well 27 the oil passes by a pipe 30 to a vacuum tank 31 from which some of the condensate is returned by a pipe 33 and a pump 34 to the fractionating tower.  The lowered pressure is maintained in the tanks by a pipe 49 connected to the pipe 28 and to each tank. Tubes 52 and pumps 53 withdraw the fractions from the tanks.  A restricted portion 54 in the tower 13 is supplied with steam by a branch 15c, oil bottoms being withdrawn by a pipe 55 and a pump 56.

Title: Preparation of aluminium hydrocarbyls
IPC: C07F5/06
Filed: 1957-06-19
Abstract: Aluminium is activated by an alkali metal, an alkaline earth metal or a hydride of these metals and simultaneously or sequentially reacted with an olefinic hydrocarbon and hydrogen. Magnesium is included as an alkaline earth metal.  It is preferred that both the aluminium and the activator be finely divided.  The activator may be used in an inert solvent, and from trace amounts up to about 25%.  Any olefin, straight or branched chain monoolefin, alicyclic olefin, diolefin or aryl olefin may be used, a terminal or a -olefin being preferred. Reaction occurs at temperatures between about 100 DEG  and 240 DEG C., at pressures between about 500 to 3,400 p.s.i., and preferably in an inert solvent such as the aluminium hydrocarbyl to be produced. Saturated aliphatic hydrocarbons such as pentane, hexane, cyclohexane, heptane, and octane and aromatic hydrocarbons such as benzene, toluene and xylene may also be employed.  Dihydrocarbyl aluminium hydrides may also be produced.  It is preferred to use both olefin and hydrogen in excess.  An inert atmosphere, e.g. nitrogen is maintained in the reaction autoclave.

Title: Improvements in or relating to radio and other transmitting and receiving systems
IPC: G01S7/03
Filed: 1946-06-28
Abstract: 613,741. Two-way transmission. SADIRCARPENTIER. June 28, 1946, No. 19468. Convention date, Oct. 31, 1941. [Class 40 (iv)] [Also in Group XL (c)] In receiving and transmitting systems where a common circuit or antenna is employed, alternate blocking of the transmitter and receiver is effected by a circuit arrangement incorporating transmission or artificial lines of one-half and one-quarter wave lengths. In Fig. 2 an impulse source 1 having terminals 2, 3 is connected by means of a transmission line 4 of length #/2 (where A is the wavelength of the waves to be transmitted) to the points 5, 6 from which a second line 7 of any length is connected to the common antenna system 10. The points 5, 6 are also connected by a transmission line 11 of length #/4 to the terminals 12, 13. These terminals are connected by means of two transmission lines 14, 15 of length #/2 to the terminals 16, 17 of a receiver 18. In the case of line 14 the terminals 12, 13 are connected respectively to terminals 16, 17, but in the case of line 15 to the terminals 17, 16 respectively. At points 19, 20 in the middle of line 15 is connected the secondary winding of a transformer 21, the primary winding of which is in the plate circuit of a discharge tube 22. The input terminals 28, 29 are fed with impulses derived from or synchronized with the impulses from the source 1, the terminal 28 being connected to the grid of the valve 22. When the transmitter 1 is in operation, negative impulses are applied to the grid of the valve 22, thereby cutting it off so that it has substantially no effect on the line 15. Under these conditions an apparent zero impedance is set up between the points 12, 13, thus causing a high impedance at the points 5, 6, and preventing energy from the transmitter travelling down the line 11. When receiving, the points 2, 3, and therefore the points 5, 6, present a high impedance to incoming signals so that no energy flows to the transmitter. At the same time the valve 22 becomes conducting due to removal of the negative pulse, so that the impedance of the points 19, 20 on the line 15 becomes very low and therefore the impedance at 12, 13 to the line 15 very high. Energy therefore travels along the transmission line 14 to the receiver 18. An alternative valve circuit for the line 15 employing two valves may be used, Fig. 6 (not shown).

Title: Improvements in or relating to memory devices
Inventor: ODELL ALEXANDER DOUGLAS
IPC: G11C11/38
Filed: 1961-05-30
Abstract: 918,343. Semi-conductor bi-stable circuits. STANDARD TELEPHONES & CABLES Ltd. May 30, 1961, No. 19511/61. Class 40 (6). [Also in Group XIX] The state of a bi-stable circuit comprising a negative-resistance element, such as a suitably biased tunnel diode, and a resistive load, is detected by applying a pulse of such polarity and amplitude to the circuit that if the circuit is in a predetermined one of its two states it will be switched to its other state, the rapid transition which occurs when the circuit is switched causing significant output to be produced by a differentiating circuit arranged in series with the negative-resistance element, while if the circuit is in the other of its two states no rapid transition will occur and no significant output will be delivered by the differentiating circuit. In Fig. 4 the differentiating circuit is constituted by capacitor C D  and resistor R 2 , the interrogating pulses being supplied from generator S. The differentiating circuit may alternatively comprise an inductor; in Fig. 6, for example, there is shown an arrangement comprising the differentiating inductor L and coupled thereto, in a sense so as to cancel the pulse appearing therein apart for the portion due to the switching of the bi-stable circuit, a further inductor M to which the interrogating pulses are applied directly. In order to be able to read out the state of the circuit without destroying the information stored therein, the output of the differentiating circuit may be applied to a halfpulse generator followed by a delay circuit, the output from which is applied with a half-pulse applied from the generator S a suitable interval after the occurrence of the interrogating pulse, the half-pulse polarities being such as to reset the circuit if a transition has occurred. Fig. 8 shows a matrix storage device in which interrogating pulses are applied in succession to inputs Y 1 , Y 2 , Y 3  and outputs are obtained from differentiating inductors L1, L2, L3. An output in any one row also excites the corresponding half-pulse generator S 1 , S 2  or S 3 , the pulse from which coincides with a subsequent half-pulse applied to the corresponding input terminal.

Title: Machine tools having platen transfer means
Inventor: ALLEN ARTHUR JOSEPH
IPC: B23Q7/14
Filed: 1954-07-08
Abstract: 771,790. Machine-tool details. ARCHDALE & CO., Ltd., J. June 30, 1955 [July 8, 1954], No. 19991/54. Class 83 (3). [Also in Group XXX] A machine-tool comprises a swarf-conveyer 9 beneath the feed-path of work-carrying platens 4 through the machine, a return-conveyer 11 below the level of the feed-path, a hoist (12, 19) adjacent each end of the conveyer for loading and unloading platens, means 15 operable transversely of the feed-path at the delivery end for transferring platens on to the hoist at that end, and means for transferring platens from the hoist at the other end to the feeding-end of machine. Platens 4 carrying work-supporting jigs are loaded by an operator at a platform 5, and then fed in turn between guide-rails to a series of stations. At each station the platens are automatically clamped, and the work operated upon for a predetermined period by tools 6. Each platen is finally fed on to a discharge-platform 7 and the work is unloaded by a second operator. The empty platen is then pushed by a piston 16 controlled by this operator against fixed stops on the machine-bed. In this position the platen operates switches to cause lowering of the hydraulically-operated hoist 12 which passes down between a pair of endless conveyer-belts or chains 11, leaving the platen deposited thereon. At the end of the stroke, the hoist operates switches to start the conveyerbelts and to carry the platen to the opposite end of the machine, where it operates a switch to stop the conveyer, and to operate the further hoist 19. The hoist raises the platen to the level of the platform 5 and operates a piston to push the platen into a position where it is reloaded by the first operator, who then closes a switch to restart the cycle. For safety, switches may be provided which have to be actuated by the operators at each end of the machine before a platen can be transferred or a machine-cycle started. In a modification, a platen is returned automatically after passing through the machine so that one operator only is needed.

Filed: 1938-07-11
Abstract: 516,830. Wireless receiving circuits. DUBILIER CONDENSER CO. (1925), Ltd. July 11, 1938, No. 20532. Convention date, July 11, 1937. [Class 40 (v)] [Also in Group XXXV] A frequency-modulated carrier is demodulated by deriving currents or voltages from two points of a resonant network fed with the signals, and applying them to the diagonals of a rectifier bridge, the demodulated output being obtained between the centre points of impedances connected across the diagonals. The phase-shifting resonant networks may comprise band filters formed of inductively or capacitatively coupled tuned circuits. The two tuned circuits L1C1, L2C2, Fig. 3, have inductive coupling and the four rectifiers G1..G4 are connected in a bridge circuit with the opposite sides 71, 72 of the input resonant circuit connected across one diagonal and the opposite sides 77, 78, of the output resonant circuit connected across the other. The demodulated voltage is obtained from terminals 73, 74 connected to the centre points of inductances L1, L2. The resistances of the rectifiers may be increased by connected high resistances in series to reduce the damping. In a modification, Fig. 4 (not shown), the tuned circuits are coupled directly by means of large inductive or capacitative impedances. In a modification, Fig. 5 (not shown), the input tuned circuit is replaced by a centretapped ohmic or inductive impedance of large value. A different type of phase-shifting circuit is shown in Fig. 7. Inductances L3, L4 are coupled to inductance L2, which supplies one diagonal of the rectifier bridge, the other diagonal of which is supplied by the tuned circuit LC which is in series with L3 and L, across the input terminals 111, 112. The output terminals 113, 114 are connected to centre taps on inductances L, L2. Demodulations may also be obtained by using a simple seriestuned circuit connected across the supply, the supply voltage being compared by means of the rectifier bridge with the voltage across either the condenser or inductance, Figs. 8 and 9 (not shown). The amplitude of the oscillations fed to the demodulator should be constant and this condition may be obtained by the use of any suitable limiting arrangements or A.V.C. circuits. The circuits described are suitable for deriving the control voltages for automatic fine tuning (A.F.C.) which may act directly on the tuned circuits or on the local oscillator if the demodulator operates at the intermediate frequency in a superheterodyne receiver. The tune-correcting voltages are derived from the output of the demodulator through a low-pass filter. The Specification as open to inspection under Sect. 91 describes also, Fig. 3 (Cancelled, not shown) an arrangement in which the phase-shifting networks supply the sum and difference of their voltages respectively to two triode rectifiers. This subject-matter does not appear in the Specification as accepted.
