Title: Method of stabilizing halogen containing polymeric substances against heat and light with salts of epoxy fatty acids
Inventor: GREENSPAN FRANK PHILIP
IPC: C08K5/098
Filed: 1954-05-17
Abstract: Halogen-containing polymeric substances, particularly polymers and copolymers of vinyl chloride, are stabilized by incorporating one or more polyvalent metal salts of a substituted or unsubstituted aliphatic acid having a straight or branched chain with 11 to 22 carbon atoms containing an epoxy ring in the chain. The polyvalent metal may be magnesium, calcium, zinc, strontium, cadmium, barium, aluminium, thallium, zirconium, lead, tin, antimony, chromium, manganese or cobalt, and the acid may be an epoxy acid derived from oleic, elaidic, erucic, linoleic, linolenic, eleostearic or ricinoleic acid, or from dehydrated castor oil fatty acids, cotton-seed oil, soybean oil, peanut oil, menhaden oil, tall oil, tung oil, castor oil or tallow, or mixtures thereof.  Preferred salts are cadmium, strontium and lead epoxy stearates, the cadmium and strontium salts of epoxidized acids of cotton-seed oil and the cadmium, strontium and barium salts of epoxidized acids of soybean oil.ALSO:Polyvalent metal salts of substituted or unsubstituted aliphatic acids having a straight or branched chain with 11 to 22 carbon atoms containing an epoxy ring in the chain are prepared by reacting the acid with an oxide or hydroxide of an alkali metal, and then reacting alkali metal salt formed in aqueous solution, generally at a temperature below 50 DEG  C., with a water-soluble salt of the desired polyvalent metal.  The polyvalent metal salt precipitates from the reaction medium and may be washed with water and a small amount of ethyl alcohol and dried by cautious heating, preferably under vacuum.  Salts referred to are the magnesium, calcium, zinc, strontium, cadmium, barium, aluminium, thallium, zirconium, lead, tin, antimony, chromium, magnesium or cobalt salts of epoxy acids derived from oleic, elaidic, erucic, linoleic, linolenic, eleostearic or ricinoleic acid or from dehydrated castor oil fatty acids, cotton-seed oil, soybean oil, peanut oil, menhaden oil, tall oil, tung oil, castor oil or tallow, or mixtures thereof.

Title: Continuous filter medium removal filter apparatus and method
IPC: B01D33/00
Filed: 1962-04-13
Abstract: 982,454. Rotary and travelling-band filters and strainers. PETERSON FILTERS ENGINEERING CO. April 13, 1962 [Nov. 6, 1961] No. 14374/62. Heading B1D. A filter of the kind consisting of an inward flow rotary drum and an endless band of filter medium associated with it has provision for maintaining the band in "track" or alignment. In Figs. 1 and 2 this takes the form of a flexible tension roller 12 located in the path of the band 2 between a cake discharge roller 8 and a back roller 15. The roller 12 is suspended from a tracking beam 10 pivoted at 11. During misalignment the beam 10 tilts at 11, whereupon the alignment-restoring forces are called into play. The roller 12 is caused to assume a convex configuration by so shaping the band (of cloth) 2 that its length at the centre is greater than that at the edges; the degree of "point" required is determined experimentally with two-part cloths which are not actually used for filtering (Figs. 11 to 14, not shown). Another form of "pointed" cloth is made from the two pieces shown in Fig. 18; edges 92 and 93 are sewn together and then edges 95, 97 are joined by zip-fastener to edges 94, 96. Instead of a flexible roller 12 there may be provided: a rigid roller rotatable on a flexible cable secured at its ends to a tracking beam as 10; or a rigid roller rotatably mounted on a tracking beam whose pivot is vertically slidable in a bracket and urged downwards by a spring. A fourth alternative is shown in Fig. 19: a rigid roller 100 mounted in a tiltable tracking beam 101 together with a bow rod 103, the latter being adjustable to vary the bulge imparted to the cloth. In the arrangement of Fig. 2 the beam 10 may be mounted at its ends on compression springs to damp its tilting movement where a light-weight cloth is used on a long filter drum. The tension in the cloth may be rendered uniform by passing the cloth over a drag roller 110, Fig. 15. The back roller 15 may be tiltable out of parallel with the drum axis to allow for non-uniform tension in the filter cloth.

Abstract: 290,636. I. G. Farbenindustrie Akt.- Ges. May 18, 1927, [Convention date]. Addition to 276,408, and 282,452. Aminoanthraquinone derivatives. - 1-aminoanthraquinone-2-sulphonic acids, substituted in the 4-position by a residue of an alicyclic amine. are obtained by replacing the halogen atoms in the corresponding 2-halogen derivatives by sulphonic groups by heating them with a neutral sulphite, preferably under pressure. The dyestuffs described in examples 1 and 2 of the parent Specifications may be obtained in this manner. In an example, 1-amino-2-brom-4-hexahydroanilino-anthraquinone is heated in an autoclave with sodium sulphite, alcohol and water and the 1-amino-4-hexahydroanilino-anthraquinone-2-sulphonic acid obtained by salting out: it is identical with the product described in example 1 of the parent Specification. The, 1-amino-2- halogen-4-alicyclyaminoanthraquinones employed as starting materials are prepared from 1-amino- 2 : 4-dihalogenanthraquinones or 1-amino-2- halogen-4-methoxyanthraquinone, by condensation with alicyclic amines in the usual manner. Thus 1-amino-2-brom-4-hexahydroanilide anthraquinone is prepared from hexahydroaniline and 1-amino-2-brom-4-methoxyanthraquinone.

Filed: 1927-05-31
Abstract: 272,212. Pescara, R. P. June 5, 1926, [Convention date]. Actuating pumps by fluid-pressure motors; compound piston pumps. - Air is compressed in stages by pistons 22, 24, 26. Fig. 1, working in coaxial cylinders of different diameters and formed integral with motor pistons 20 working in an internal-combustion cylinder. After compression in the first and second stages the air passes through coolers 37, 50 to reservoirs 33, 46, from which pipes lead to the next higher stage; the final stage delivers to a reservoir 57. The outlet valves 59 in the high-pressure cylinder lead from passages in the cylinder sides, which are covered by the piston near the end of its stroke, leaving a cushion of compressed air to return the piston. Fig. 2 shows a modification in which the motor piston 122 surrounds the first stage compressor piston 120, leaving an annular space 169 in which a gas cushion is compressed by a fixed cylindrical projection.

Title: Traffic detectors
IPC: G08G1/042
Filed: 1945-06-08
Abstract: 613,021. Road signals for controlling traffic. AUTOMATIC SIGNAL CORPORATION. June 8, 1945, No. 14618. Convention date, June 1, 1944. [Class 118 (ii)] [Also in Group XL (c)] Apparatus for detecting the passage of traffic in a pre-determined path comprises an oscillator energized when .the passage of a traffic unit actuates a switch, means for transmitting the oscillations in the form of ground currents, remote receiving means, and indicating or control means actuated by the said ground currents. As described, a vehicle actuated road-pad 10 closes contacts 12, 14 to energize an oscillator 15 and radiate controlledfrequency currents from rods 19, 20 buried in the ground. These ground currents are detected by spaced rods 30, 31, amplified and rectified by a receiver unit R and utilized to actuate a relay 35 in a traffic detection, control, counting or like circuit. Closing of the switch 12, 14 supplies heating current to the filament of the oscillator 15, but since the average duration of operation of the switch is .003 second, the filament would not reach emission temperature before the actuating vehicle had again opened the switch 12, 14. To overcome this difficulty, closing of the switch 12, 14 applies, via a condenser 25, a substantial overload voltage to the filament. The condenser 25 completely charges in 0.2 second and the filament voltage is thereafter dropped to the normal rating for the valve 15 by a resistor 24 to prevent continued overload of the filament should a vehicle remain on the actuating pad 10 for a long time.

Title: Improvements in automatic reclosing circuit breaker systems
IPC: H02H3/06
Filed: 1924-06-21
Abstract: 222,830. British Thomson-Houston Co., Ltd., (Assignees of Anderson, A. E.) Oct. 3, 1923, [Convention date]. Electric protective systems; cut-out arrangements. - Relates to automatic reclosing circuit-breaker systems in which the circuitbreaker 3 connects to circuits A, B which are independently energizable either together or singly, the system being adapted to allow the breaker to open if either one or both of the circuits be energized. Voltage coils 5, 6 are connected to the conductors 1, 2 of the circuits the circuit of the coil 6 being incomplete unless the coil 5 i.e., the circuit A is de-energized. If circuit A alone is energized circuit is completed at 12 for the closing coil 4 of the breaker; if cir. cuit B alone is energized, the voltage coil 6 is energized and a circuit for the closing coil 4 is completed through the contacts 16. The breaker is adapted to open if there is a heavy straight through current from one section to another, an overload relay 10 with the usual dash-pot 11 being provided, which, on actuation, breaks the circuit of the coil 4 at 13. It may happen, if both circuits are simultaneously energized, that both circuits of the coil 4 may be momentarily established but the resistors 7, 8 prevent the passage of any but feeble currents. In the modification shown in Fig. 2, the overload relay controls the closing coil 20 of a second breaker 21, which on opening inserts a resistor 22 between the circuits A and B and so limits the current flowing between them. Overheating of this resistance causes a thermocouple 25 to break the circuit of the coil 5 and closes a shunt round the coil 6-or breads the circuit of this coil-so deenergizing the coil 4 and opening the breaker 3. Modifications are also described in which the circuits A, B have metallic returns instead of a common earth return.
