Title: Improvements in or relating to control systems
IPC: G01C19/36
Filed: 1944-09-29
Abstract: 612,307. Automatic control systems for gyroscopes. SPERRY GYROSCOPE CO., Inc. Sept. 29, 1944, No. 18689. Convention date, May 29, 1943. [Class 38 (iv)] [Also in Group XX] Alignment.-In a closed sequence control system for a variable, an A.C. signal in response to error starts an oscillator, the output of which controls servo-means effecting correction. In Fig. 1, a three-legged flux valve 1, pendulously supported (Fig. 2, not shown) on a craft, has exciting coils 2, energized from an alternating current source 5, and output coils 3 giving a voltage dependent on their position relative to the earth's field. The output from coils 3 is applied to the three-winding stator 6 of a remote Selsyn type unit, the rotor 8 of which is fixed to the vertical gimbal ring of a directional gyro (Fig. 2, not shown). The arrangement is such that the field produced by the stator 6 is fixed in space despite movement of the craft in azimuth and, provided the vertical ring of the gyro also remains fixed in space, no voltage is induced in rotor 8. Wander of the gyro, however, displaces rotor 8 relative to the stator field and a voltage proportional to the displacement is induced in rotor 8, its frequency being that of source 5 and its phase being dependent on the sense of the displacement. Rotor 8 forms with a condenser 9 a tuned circuit, the voltage across which is applied to the grid circuit of a pentode oscillator valve 11 which oscillates at half the frequency of source 5 whenever the rotor voltage is above a value corresponding to a small displacement of the gyro. The output from the oscillator when oscillating is independent of the voltage, but dependent on the phase of the rotor output and is amplified by a triode valve 22 and applied to a phase-sensitive double-diode valve 26, the anode currents of which, derived from source 5, selectively operate a two-way relay 28 according to the phase of the rotor voltage to energize an electromagnet 38 precessing the gyro in the appropriate sense for correction. In a modification, Figs. 3-5 (not shown), a single-legged flux valve is pendulously supported by the vertical ring of the gyro and the Selsyn type transmission dispensed with. Any suitable D.C. amplifier and torque motor may be substituted for relay 28 and electromagnet 38 respectively. If a two-phase torque motor is employed to precess the gyro, one phase may be controlled and the other supplied from a constant source such as source 5. Application of the invention to preventing wander of a gyro relative to a vertical reference is referred to. Specifications 600,189 and 604,907, [both in Group XXXVI], are referred to.

Abstract: 1,273,622. Settling plant. PATERSON CANDY INTERNATIONAL Ltd. 12 June, 1970 [11 April, 1969], No. 18743/69. Heading B1D. A settling plant comprises a clarified liquid chamber 1 with overflow outlet 9, a raw liquid chamber 2 with agitator 7, a system of settling tubes or channels 3 joining the two chambers for the deposition in the tubes of suspended matter during the passage of liquid from chamber 2 to chamber 1, and a movable distributor 5 which supplies raw water selectively and cyclically to each of a plurality of groups, e.g. vertical columns, into which the tubes are divided. The raw water flow from the distributor acts both to supply the raw water to chamber 2 and to wash into the chamber 2 sediment deposited in the tubes. The concentration of solids in chamber 2 is regulated by bleeding the solids therefrom. The settling plant may alternatively be in the form of concentric circular chambers 1 and 2 having an annular system of tubes being disposed between them in which case either the tubes and chambers are fixed but the distributor is mobile and rotates in a circle around the inner wall of the chamber 1 (Figs. 4 and 5 not shown) or the two chambers and the distributor are fixed and the annular system of tubes rotates (Figs. 6 and 7 not shown). Several specific forms of distributor are described.

Title: Improvements in producing resinous condensation products of the urea-formaldehyde type
IPC: C08G12/12
Filed: 1926-07-28
Abstract: 256,248. Rohm & Haas Co., (Assignees of Lauter, F'.). July 28, 1925, [Convention date]. Urea-formaldehyde and like condensation prodiects.-In the manufacture of condensation products of urea, thiourea or their derivatives with formaldehyde, the aldehyde is dissolved in an organic solvent such as alcohol, benzene, toluene. acetone, or carbon tetrachloride, and is mixed with the urea &c. in the presence or absence of a polyhydric alcohol, such as glycerol or an ester thereof. The products possess water-resistant properties, whilst those made in the presence of a polyhydric alcohol are flexible and can be used for the manufacture of photographic films. Preferably 2.7 moles of formaldehyde are employed to each mole of urea, with an additional mole of formaldehyde for each mole of glycerol present, which latter however should not exceed the proportion of 1.2 moles of glycerol per mole of urea. The formaldehyde may be employed in the form of its polymers or derivatives, such as paraformaldehyde or hexamethylenetetramine. Acidic or basic condensing agents or both may be present. If the condensation product is to be used as a lacquer or varnish, some of the solvent is allowed to remain; otherwise, the whole of the solvent is driven off by heat to obtain a hard product. The hardening may be effected under pressure to produce a moulded product. According to the examples, (1) paraformaldehyde is dissolved in hot methyl alcohol containing a little ammonium hydroxide, urea is added, and the mass is concentrated ; (2) in a heated mixture of acetone and ammonium hydroxide, paraformaldehyde is dissolved and an acetone solution of urea then added ; after heating for some time, a little nitric acid is added and the mass again heated; (3) paraformaldehyde is dissolved in hot ethyl alcohol containing ammonium hydroxide, urea and glycerol are added, and the mass heated; a little nitric acid is further added and boiling continued until the desired consistency is reached. The Specification as open to inspection under Sect. 91 (3) (a) comprises the use of aldehydes in general. This subject-matter does not appear in the Specification as accepted.

Abstract: 979,503. Transistor saw-tooth generators. GENERAL ELECTRIC CO. Ltd. May 25, 1961 [May 27, 1960], No. 18888/60. Heading H3T. A saw-tooth generator includes a capacitive element, a constant current diode, having a current/voltage characteristic as shown in Fig. 2, and means for charging and discharging the capacitive element via the diode. In operation terminal 6, Fig. 1, is maintained at a negative voltage of 21 volts and a series of negative going pulses are applied to the base of a transistor 4 connected in parallel with the series combination of constant current diode 7 and capacitor 3. During each interval between consecutive pulses transistor 4 is cut-off and a reverse voltage of about 20 volts appears across diode 7 so that a constant current of 200 microamps charges the capacitor 3. The capacitor continues to charge until a further current pulse is applied to the base of the transistor causing the latter to saturate and resulting in the diode 7 being biased in the forward direction such that the capacitor discharges rapidly through the low impedance path now presented by the diode. A sawtooth waveform, Fig. 5 (not shown), is obtained from across terminals 1, 2. Specification 916,346 is referred to.

Patent GB-1007707-A (GB)
Title: Improvements in and relating to the production of unsaturated carboxylic acids
Inventor: LONG RICHARD
IPC: C07C51/14
Filed: 1962-05-17
Abstract: Unsaturated carboxylic acids are made by reacting a p -allylic complex of palladium chloride, especially p -allyl or methally palladium chloride, with carbon monoxide, preferably at 10 DEG  to 150 DEG  C., atmospheric to 1000 ats. pressure, optionally in a solvent, e.g. a liquid hydrocarbon, preferably n-hexane, cyclohexane, benzene or toluene, and hydrolysing the product with water.  At least partial double bond migration can be achieved by carbonylation and/or hydrolysis at 100 DEG  C. or above.  The p  complex is preferably obtained by the direct reaction of palladium chloride with propylene or a higher olefine, which may be straight or branched chain, or cyclic, e.g. cyclohexene.  Alternatively, the complex may be obtained by reacting an unsaturated alcohol or unsaturated chloride with palladous chloride.  Thus, p -methallyl palladium chloride may be obtained from isobutene, p -allyl palladium chloride from propylene, and palladium chloride, while taking steps, e.g. by gas purging or adding an alkaline substance, e.g. sodium carbonate or acetate, to remove hydrogen chloride.  In the examples p -allyl palladium chloride is converted to 3-butenoic acid, p -methallyl palladium chloride to 3-methyl 3-butenoic acid and p -crotyl palladium chloride to 3-pentenoic acid.

Title: A device for controlling the supply of liquid to a distillation apparatus
IPC: B01D1/00
Filed: 1954-07-02
Abstract: <PICT:0784401/III/1> A still F for the distillation of liquids is connected to a distilland supply tank C2 via a control device which operates in such a way that some of the liquid alternately fills and empties a perforated cone H1 attached to the base of a vertical tube H forming part of the device, whereby small and frequent measures of liquid are delivered to the still.  The control device comprises a cylinder C1 in which is mounted, centrally and vertically, the tube H which is open at the top; the lower end of tube H depends into tank D.  The cone H1 is brazed into the lower end of tube H so that the base of the cone is cut 10 degrees from the horizontal to form an ellipse; and a 1/8 inch hole is drilled diametrically opposed to the upper edge of the inclined base.  Cylinder C1 is connected to supply tank C2 by liquid-pipe B3 and by an airpipe H2.  Tank D is open at the top, so that it is always under atmospheric pressure.  Distilland is introduced into tank C2 through line B2, and it flows into cylinder C1 via pipe B3.  While the filling process is in operation, air passes down tube H and escapes to the atmosphere via the hole in cone H1.  When the containers are filled to capacity, tap W2 is closed and tap W1 is opened to allow the liquid to flow through pipe H3 to tank D.  When the liquid reaches level O it seals off cone H1; but the flow continues until a vacuum is created in tank C2, cylinder C1 and tube H, and a column of liquid is drawn up into tube H whereby all three hydraulic levels are equalized.  The still F, which may be heated by a hot water-bath, is now charged by opening tap W3.  When the liquid-level in tank D drops below cone H1, the liquid in the cone is rapidly emptied into the tank, its volume being instantly replaced by air.  This air expands up tube H and has access to cylinder C1 and tank C2; and a proportionate volume of liquid passes through pipe H3 into tank D, thereby restoring the liquid level O and cutting off the air flow into tube H.  A repetition of the cycle takes place until the liquid level in the still is equal to that in tank D.  The same cycle occurs when the level in the still falls owing to the distillation.  The Specification refers to the recovery of methylene chloride.
