Abstract: 768,918. Gas filters. HERSEY, H. J. April 27. 1955 [May 7, 1954], No. 12132/55. Class 8(2) Reverse flow of cleaning air through at least one of a plurality of inward flow air filter sleeves 32 Fig. 1 is effected by a plunger 16 mounted in a housing 17 of large volume relative to the filter sleeves and connected by an opening 25 to the downstream side of the sleeves whereby during its working stroke the plunger forces compressed air through the whole of the sleeve in counterflow to the dust laden air flow which is at positive pressure. As shown six sleeves 32 of matted glass, asbestos fibre or wool felt and radially arranged in a housing 11 having a tangential inlet 36 are suspended by bellows 30 from an apertured plate 14 through which cleaned air is discharged to a cylindrical space 13 and an outlet 37. The plunger housing 17 has a downwardly extending central sleeve 17a rotatably mounted within a hub 18 and is continuously driven from a drive shaft 38 through a pinion 41 and a ring gear 64. The plunger 16 is held at the top of its stroke against a spring 23 by a rope 43 secured to a pulley 42 held by engagement within one or other of recesses 46a - - - d Fig. 5 of the nose 45 of a dog clutch 44 pivoted by a pin 52 to rotate with the shaft 38. Disengagement of nose 45 from the pulley 42 so as to allow the plunger to make its working stroke is effected when a fixed pedestal 51 is engaged by a lug 49 of the rotating dog 44. A second lug 50 projecting from the dog 44 may abut a pivoted cam plate 55 and the dog held away from pulley 42 when said plate is held in the position shown in Fig. 5 by a crank 56 rigidly secured thereto, a link 57 and a bellows 58 connected by a duct 59 to the filter inlet 36. High back pressure results in expansion of bellows 58 and pivotal movement of plate 55 thereby releasing lug 50 and allowing the dog 44, 45 to engage the plunger actuating pulley 42. A plurality of annular brushes 61 Fig. 7 (not shown) surrounds each filter sleeve 32 and brushes dirt therefrom on reciprocation of the sleeves permitted by the bellows' 30.

Title: N-substitutedphenylsulfonyl-n-cycloalkylureas and processes for preparing same
IPC: C07C303/36
Filed: 1961-04-05
Abstract: The invention comprises compounds of the formula <FORM:0912789/IV (b)/1> and non-toxic cationic salts thereof, wherein R is cyclohexyl or cycloheptyl and X is the group -CO- or -CHOH- and non-toxic cationic salts thereof, and their preparation by treating an amide, imide or isocyanate having at least one para-substituted phenyl radical of the formula CH3.X.C6H4.SO2- with an isocyanate or an amine having a cycloalkyl radical and if desired concurrently or subsequently reacting with a base or basic salt and/or if X is a -CO- group, hydrogenating to produce the corresponding carbinol. Suitably, for example an ethyl phenylsulphonylcarbamate or a phenylsulphonylisocyanate is reacted with cyclohexyl- or cycloheptyl-amine; an N-cycloalkyl urethane is reacted with a phenylsulphonamide or the reaction product of two molecules of a p-substituted phenylsulphonamide is pyrolyzed with a cycloalkylamine. If the starting material is a carbinol (X = -CHOH-), the hydroxy group may be protected by an acyl or alkoxycarbonylamino group which is subsequently removed by hydrolysis.  p-Acetylbenzenesulphonamide is made by converting p-aminoacetophenone to p-acetylbenzenesulphonyl chloride by diazotising and reacting with sulphur dioxide and cupric chloride, which is then reacted with ammonia.  N - p - acetylphenylsulphonyl - carbamate is obtained by treating the above sulphonamide with ethyl chloroformate.  Pharmaceutical preparations useful as antidiabetic agents comprise the compounds of the invention in oral dosage forms such as tablets or capsules containing conventional binders, fillers or other excipients.

Abstract: 652,657. Programme transmission. RADIO CORPORATION OF AMERICA. May 5, 1948, No. 12366. Convention date, May 22, 1947. [Class 40 (iv)] [Also in Group XL (c)] In a signalling system comprising two amplifiers or two transmitters, one being in use and the other spare, a relay circuit dependent on the relative magnitudes of the electrical energy at the input and output of the amplifier or transmitter in use switches in the spare amplifier or transmitter and disconnects the one in use when the relative magnitudes change. As shown, the input is fed to the regular amplifier 2 and the output is fed through contacts 5 and 7 of a relay to the output transformer T, a portion of the output being supplied to a rectifier 9. The emergency amplifier 3 and an amplifier 4 for the relay circuit are also connected to the input, the output of the amplifier 4 being supplied to a rectifier 11 connected to rectifier 9 and arranged to provide a zero or slightly negative potential at the junction 10 of the rectifiers. A relay amplifier 12 is connected to the junction 10 and under normal conditions the relay is inoperative and the amplifier 2 supplies the output, loss of gain or failure of the amplifier 2 causing the rectified component from rectifier 11 to become greater than that from rectifier 9 with a resultant positive potential at the junction 10. This causes the relay to operate and connect the amplifier 3 to the output transformer through contacts 6 and 7, contacts 14, 15 operating an alarm circuit, and contacts 16, 17 completing a holding circuit. The amplifier 2 may be switched back into circuit by opening the switch 19. In an alternative arrangement, Fig. 2 (not shown), the relay amplifier 12 is replaced by a thyratron valve, this eliminating the need for relay contacts 16, 17. The system may be applied to a radio transmitter and emergency transmitter, Fig. 3 (not shown), or used in programme material amplifiers and circuits for relaying material to telephone lines, and utilized to keep the equipment in operation although unattended.

[Also in Division F2] A centrifugally actuated valve carried by a resilient arm 7 mounted on a rotating shaft 1 comprises a hemispherical element 5 coacting with a seat 3 terminating a spill passage 2 from, e. g., a positive displacement fuel pump of an internal combustion engine or gas turbine, and a centrifugal weight in the form of a ball 10 which is carried in a radial bore 12 of a holder 11 which is splined to the shaft 1 to rotate therewith but is adjustable axially thereof by a shaft 14 to vary the opening force applied to the valve at a given speed of rotation. The shaft 14 has an abutment 19 operating between adjustable stops 22,23 and is connected to the holder 11 by a bearing 17. The shaft 1 may be balanced by the provision of a dummy arm 7a and weight 10a. In a modification, the holder 11 is spring loaded and adjusted by variation of fluid pressure admitted through a passage in the shaft 1 to a chamber enclosed by the holder. In a further modification, the weight acts on the arm 7 between the valve element and the mounting point of the arm, and the arm may be backed over part of its length by a stiffener. The arm may be forked at its mounting point, the stiffener may extend between the forked portion, and the weight holder may be so adapted that it can be positioned where it enables the weight to exert on the stiffener a force assisting the action of the resilient arm 7 on the valve element.

Filed: 1944-06-30
Abstract: 597,155. Protective cut - out systems. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. June 30, 1944, No. 12455. Convention date, Aug. 26, 1942. [Class 38(v)] In an electrical system, a plurality of circuits e.g. a supply circuit 3, a distribution feeder 5 and a tie circuit 7, are connected to a bus 1 through circuit-breakers 11 and disconnecting switches 13, 15. A differential relay 18 partially energised from each circuit by current transformers 25, affords protection of the portions of the system above the transformer 25 as viewed in Fig. 1, the remaining parts of the system being protected by over-current relays 27 energised by current transformers 29. In the event of a fault occurring at F, the balance of current entering and leaving the bus 1 is disturbed resulting in relay 18 closing its contact 19 to effect the tripping of all the circuit-breakers 11. Should a fault occur at G, this joint being outside the zone of protection afforded by relay 18 only results in the energisation of the relay 27 associated with line 5 consequently only tripping the circuit-breaker 11 in line 5. Fig. 4 illustrates a compact arrangement of the apparatus associated with each circuitbreaker 11 which may be that of Specification 563,641 wherein the current transformers 25, 29 are mounted in a single insulating housing 39, the current transformers 25 being mounted on the line side to afford " overlapping " protection over the portion of the system between the current transformers. In order that proper selective operation of the relays may obtain in the event of line 5 being subjected to an abnormally high voltage, the insulation of the housing 39 and supports 47, 49, 51 for the circuit-breaker 11 and switches 13, 15 is graded by the provision of spark gaps 53, 55; 57, 59; 61, 63 and 65, 67. The spark-gap 53, 55 nearest the line 5 is set to have the lowest break-down voltage so that the presence of an abnormal voltage on the line 5 results in the break-down thereof, the restriction of the break-down to this point thereby ensuring that only the relay 27 associated with the faulty line 5 is energised to trip the circuit-breaker 11 thereof, since the said point of break-down is outside the zone of protection of relay 18.
