Title: Improvements relating to delivery of sheets from webcutting machines
IPC: B65H33/14
Filed: 1939-12-29
Abstract: 599,426. Sheet-delivery apparatus. MOORE, J., and MOORE, K. B. Dec. 29, 1939, No. 33035. [Class 100 (i)] [Also in Group XXX] Sheets cut from one or more webs are delivered without overlapping by a parallel tape conveyer and diverted to one or other of two pile tables by a deflector comprising a number of tongues movable between an inoperative position in which' they lie on one side of the conveyer surface and an operative position in which they project through the tapes. As shown, the sheets are delivered from the cutting-machine by tapes 1 which move slightly faster than the draw-rollers of the machine. Near the delivery end of the tapes 1, a deflector comprising a series of tongues 8 is situated, and can be set either so that the sheets pass via a conveyer 2 to an automatically-lowered pile table 3 or so that the sheets are deflected through guides 10 to conveyers 6, 7, 13, which carry them over the first table 3 to a similar table 3<1>, both tables having stops 4. The conveyer 7 is sufficiently high to be clear of operators dealing with the table 3 and may be long enough to permit of withdrawal of the table 3 in a longitudinal direction. Further the table 3<1> may be at a higher level than the table 3. The sheets may be slowed down and caused to overlap before reaching the tables by sagging tapes 12, 12<1>. The deflector tongues 8 are moved about their pivot 9 by electromagnets 20, 20<1>, controlled by a snap-over contact-arm 18 operated by relays 16, 16<1> when buttons 14, 14<1> respectively forming a remote control are pressed. Sheetdetector contacts 23, 24 in the relay circuits interrupt the circuits if a sheet is passing between them. Blowing action may be provided to assist the guidance of the sheet by the deflector. In a modified arrangement, laying-off means which is raised as the pile grows is provided, including a conveyer pivoted at the end remote from the pile so that the end adjacent to the pile rises as the pile grows.

Abstract: 466,503. Luminescent screens. GENERAL ELECTRIC CO., Ltd., and RANDALL, J. T. Nov. 28, 1935, No. 33051. [Class 98 (i)] [Also in Group XL] A luminescent material adapted to be excited by the rays from a mercury vapour discharge lamp consists of a matrix mainly of cadmium silicate with an activating impurity preferably manganese. The material is prepared by mixing pure cadmium oxide with a silica prepared by the reaction between silicon tetrachloride and water, followed by vacuum drying of the silica at 150‹ C. The mixture is approximately in the proportion of 1 part of cadmium oxide to two parts of silica, and manganese chloride is added in sufficient quantity to give À5 per cent of manganese in the final product. The mixture is dried in vacuo at 180‹ C. for 3 or 4 hours in a silica boat and the temperature is raised slowlv so that it reaches 1000‹ C. in 2 hours. It is maintained at this temperature for about 1 hour, then cooled and powdered. The material has a rose-white colour under the rays from a mercury vapour and argon lamp, but the colour may be modified by the addition of other substances such as calcium tungstate.

Title: Preparation of pelletized solid materials
Inventor: TUTTLE FREDERIC CHANLER
IPC: C07C39/44
Filed: 1964-08-13
Abstract: Pellets of alkali and alkaline earth metal chlorides or silicates, such as sodium or calcium chloride or silicate, are formed by spray coating particles of the material with an aqueous solution thereof in one or more dilute zones in a fluidized bed, said zones being formed by injecting steam into the bed transverse to the flow of circulatory air.  As in Fig. 1, particles of the material are fluidized in a vessel 1 by a stream of heated air from heater 6, which passes upwards through screen 10.  Steam under pressure, together with a saturated aqueous solution of the material, is injected into the fluidized bed through a bifluid nozzle 1 and forms a dilute zone, as shown, in which the particles are coated, a solid coat being formed by the subsequent evaporation of the water. The pellets thus produced are drawn off through line 18 and elevator 3 to a screening mechanism 4, whence the oversized pellets are crushed at 5 and reintroduced to the bed through line 24, the underized pellets reintroduced through lines 22 and 24, and the pellets of the required size discharged into storage means through line 21.  Any particles carried upwards, by the air, pass through line 16 to a cyclone 2 whence they are reintroduced into the bed through line 24.ALSO:Pellets of alkali metal pentachlorophenates such as sodium pentachlorophenate, or of alkali metal sulfonates of alkylated diphenyl oxide, are formed by spray coating particles of the material with an aqueous solution thereof in one or more dilute zones in a fluidized bed, said zones being formed by injecting steam into the bed transverse to the flow of circulatory air.

Filed: 1921-12-09
Abstract: 172,643. Instrumentaktiebolaget Navigator. Dec. 9, 1920, [Convention date]. Integrating.-Relates to an integrating-mechanism for deriving, from a ship's speed-meter of the Pitot-tube kind wherein a difference of fluid pressures is established proportional to the speed through the water, the distance travelled, by an integration of such pressure-difference with regard to time. An arm 25 is caused by any convenient means to oscillate, with a constant angular velocity, between two stops 49, 51, of which the movable stop 49 is carried by an arm 48 adjusted according to the pressure-difference in such manner that the distance between the stops is maintained inversely proportional to the speed of the vessel. Each time an extension 50 upon the oscillating arm strikes the other stop 51, an escapement pallet 52 is rocked sufficiently to permit of a unit-movement of the counting-train 53 of the distance indicator. Alternatively the non-adjustable stop 51 may control a counting- train at a distance by pneumatic means. A second counter or distance indicator may be driven from the first.
