Abstract: 386,215. Automatic exchange systems. RUMPF, F., 8, Sohwanengaase, Berne, Switzerland. June 1, 1932, No. 15558. Convention date, June 2, 1931. [Class 40 (iv).] In a system in which full automatic toll service is provided, the calling subscriber is informed of the number dialled by call announcer apparatus. As shown, the calling line is extended over 1st and 2nd group selectors to the relay J which energizes I. Subsequent digits are repeated to the magnets D1, D2, D3 of registers W1, W2, W3, of which there may be a number sufficient for recording the calling and wanted numbers and which select leads carrying voice currents corresponding to the digit registered derived from gramophone apparatus. Series relay II energizes relay III to cause an impulse to be delivered to the sequence switch magnet DVW at the end of each train. On going off normal the sequence switch energizes IV and changes over contacts nvw. When all the digits have been registered, IV is released and puts the driving magnet of the switch AW under control of contact k which is operated intermittently so that the registers are connected up, in turn and an announcement of the numbers dialled is sent back to the line via the transformer U.

Title: Process of continuously gasifying solid carbonaceous material in a rotary kiln
IPC: C10J3/06
Filed: 1976-09-20
Abstract: 1516000 Gasifying carbonaceous material in a rotary kiln ALLIS-CHALMERS CORP 20 Sept 1976 38820/76 Heading C5E Solid carbonaceous material, particularly coal, which exhibits a tendency to agglomerate at a predetermined rate depending on its free swelling index after it attains a first agglomerating temperature and which loses the tendency at a second higher non-agglomerating temperature, is gasified in a rotary kiln by (a) admitting sufficient heat to a tumbling bed of the material in a devolatilizing zone to raise the temperature therein to the second higher non-agglomerating temperature before the agglomerates have been exposed to the first agglomerating temperature for a length of time sufficient for the agglomerates to have grown to a size greater than a predetermined agglomerate size which is determined by the capability of the kiln to allow movement of the material therethrough, (b) admitting steam to the tumbling bed in a gasifying zone of the kiln downstream of the devolatilizing zone to cause gasification of the material of the bed therein and (c) continuing the tumbling of the material to ensure that an agglomerated material which has attained the non-agglomerating temperature will be broken up before the material is discharged from the kiln. A preheating zone may be arranged before the devolatilizing zone, the temperature of the material not attaining the agglomerating temperature until it has reached the devolatilizing zone. It is preferred to use air in the devolatilizing zone to raise the temperature of the material rapidly from 700‹F to 1600‹F.

IPC: C08G59/12
Filed: 1961-11-15
Abstract: The invention comprises an epoxide resin-forming compound of th formula <FORM:1026141/C2/1> in which the two acid residues R1(CO-)2 are derived from the same dicarboxylic acid, the said acid being capable of forming an internal anhydride, preferably an aryl dicarboxylic acid, and -OR2O- derives from a glycol. The epoxy compound may be made by the steps (a) reacting two molecular proportions with one molecular proportion of a glycol and (b) reacting the dibasic acid thus formed with epichlorhydrin in the presence of an amine catalyst, including a quaternary ammonium salt. Preferably the dicarboxylic anhydride is phthalic anhydride and the glycol is ethylene glycol.  Step (a) can be effected by warming the components to 110 DEG  C.  Step (b) is carried out by heating the sodium salt of the dibasic acid product of (a) with excess of epichlorohydrin to 120 DEG  C. in the presence of tetraethyl ammonium bromide or by heating the free dibasic acid product with epichlorhydrin in the presence of an amine catalyst such as tetraethyl ammonium bromide at 80-100 DEG  C. and converting the chlorohydrin product to a di-epoxide by treatment with an aqueous alkali in the presence of a solvent.  The chlorohydrin product may also be converted to a di-epoxide by heating it with excess epichlorhydrin in the presence of a quaternary ammonium salt. Other glycols such as propylene glycol or neopentyl glycol, and other anhydrides such as tetrahydrophthalic, maleic or hexachloroendomethylene tetrahydrophthalic anhydride may be used.ALSO:An epoxide resin is made by hardening a compound of the formula <FORM:1026141/C3/1> in which the two residues R1(CO-)2 are derived from the same dicarboxylic acid, which is capable of forming an internal anhydride, and -OR2O- is a glycol residue, by heating with phthalic anhydride at 130-140 DEG  C., or by action of acids such as phosphoric or phthalic acid, or amines such as ethylene diamine or tetraethylene pentamine.

Abstract: 933,608. Automatic speed control. RADIO CORPORATION OF AMERICA. Dec. 2, 1959 [Jan. 2, 1959], No. 41029/59. Class 38 (4). The pressure between a magnetic pick-up head 30 and a magnetic tape 10 is varied in accordance with a correction signal to vary the location deformation of the tape and thereby compensate the reproduced electrical signal for variations in the relative speed between the tape and head. Synchronizing components of a television signal derived from circuit 66 are applied to a comparator circuit 68 which compares the synchronizing signals from the tape 10 with signals from a standard generator 70. A D.C. error signal, which varies in magnitude according to the relative phase of the compared signals, is applied to a network 72 to compensate for undesirable constant phase delays in the servo system. The error signal is then applied to a D.C. power amplifier having its output coupled to solenoid 56 to vary the pressure between polepieces 42, 44, 46 on the head 30, and the tape 10 over grooves 22, 24, 26, in capstan 18. The variation in pressure causes a variation in the deformation of the tape and in the instantaneous velocity of the tape relative to the head. Accordingly, the signal derived by the head 30 changes the phase and frequency of the separated synchronizing components of the reproduced television signal until coincidence thereof with the locally generated signals is attained. When no correction is required the distortion of the tape is one half of the maximum, to permit correction in either direction. Average speed variations are corrected by a brake 76 coupled to the motor 28 driving the capstan 18. Control current for the brake is derived from amplifier 78 which amplifies the error signal from the comparator 68, a phase correction network 73 being provided.
