At a rotating station, a rotation means (70) rotates one of the plates containing the product for spreading the coating on the product. After rotation, a first elevator (302) transfers the plates from the conveyor (90) to a dryer (300) disposed above the conveyor. A second elevator (304) transfers the plates from the dryer back to the conveyor for further processing. The dryer includes complementary acting pusher bars (332) for transporting a plurality of plates horizontally along a plurality of vertically spaced guides. The plates are transported upward to traverse the guides through a first section of the dryer and downward through a second section of the dryer by the combined action of the first and second elevators and a mid-elevator (322). Several embodiments for the elevator are disclosed which include a lift bar mechanism (354), a continuous chain mechanism (376) and a lift rod system (400). <IMAGE>

Se conocen ciertas formulaciones de la olanzapina en tableta, según se describe en la patente de los Estados unidos de norte América No. 5229.328. Sin embargo se desean formulaciones orales mejoradas en vista de la naturaleza sensible a la humedad y metaestable de la olanzapina y su tendencia a descolorarse de una manera indeseable en la formulación conocida en tableta es decir la formulación revelada en 5229.328¿a la naturaleza sorprendentemente potente de la olanzapina. Se desea especialmente una formulación farmacéuticamente elegante en gránulo o micropartícula. Esta formulación granular fue particularmente difícil en vista del efecto exacerbante del contacto de la superficie con el aire ambiental y ambientes húmedos y el área superficial relativamente grande inherente a una formulación granular. La descoloración y apariencia moteada no produce un incremento en el número de sustancias totales relacionadas; sin embargo, el cambio de color y apariencia generalmente no se considera farmacéuticamente deseables. El cambio de color podría ser particularmente indeseable para los pacientes que sufren de trastornos sicóticos. En verdad, el paciente que mas probablemente recibirá la olanzapina en un paciente que sufre de alucinaciones, delirios y pérdida de contacto con la realidad. Por lo tanto, es muy deseable obtener una formulación que tenga un olor y apariencia constantes.

Abstract: 1,052,334. Thermal switches. CALOR APPAREILS ELECTRO - DOMESTIQUES. April 28, 1964 [May 9, 1963], No. 17585/64. Heading H2B. [Also in Division G1] A thermostat for an electric iron utilizes the difference in expansion between the iron soleplate 10 and a rod 12 of substantially non- expanding material, e.g. " Invar " (Registered Trade Mark) to actuate switch contacts 35, 64 to control the heater for the iron. The rod 12 is fixed at one end to a member 14 on the sole-plate 10 and at the other end is secured to a pin 49, engaging a lever 46, the lever 46 being pivoted at 50 to a fixed assembly on the plate 10. The fixed assembly 24 carries a cam 32 on a spindle 28 and an insulating block 42 supporting blades 34, 36. The blade 36 carries an insulating block 44 engaging the cam 32, and is provided with a knife edge 38 to contact the blade 34. A spring 40 is provided between the blades 34, 36 and the blade 34 is snap-acting between the position shown in Fig. 1 where the contacts 35, 64 are in engagement and a position wherein they are disengaged. The lever 46 carries by way of an insulating block 58 a movable assembly 56, with the contact 64 and an adjustable insulating stop member 62. A spring blade 52 acts on the lever 46 although a coil spring may be substituted. In operation, as the soleplate expands the movable assembly moves so that the contact 64 forces the blade 34 to pass from the position shown to its other position to cut-off the supply to the iron heater. The temperature at which this occurs is controlled by the position of the cam 32 which is adjusted normally by the operator. As the temperature falls the stop member 62 will ensure the return of the contacts to their closed position. An insulating stop member 70 is also provided on the assembly 24. In an alternative embodiment the lever 46 may incorporate pivot-pin connections with the rod 12 and assembly 24.

Abstract: 1,239,413. Centrifugal pumps; hydraulic turbines. SOC GRENOBLOISE D'ETUDES ET D'APPLICATIONS HYDRAULIQUES. July 26, 1968, No.35905/68. Headings F1C and F1T. During standby running of an intermittentlyoperated rotary-hydraulic machine such as a turbine, pump or pump-turbine, the power absorbed is reduced by first draining the machine and then reducing the pressure of the air in the machine, e.g. to a value between one fifth and one tenth of the normal atmospheric pressure. In the installation shown, a pump 3 and/or a turbine 2 are drained by pumps 12, 13 assisted, if desired, by compressed air, and evacuated by a vacuum pump 19. Valves 4, 6 and 8, 10 provide the necessary isolation of the machine. Leakages into the drained and evacuated machine are countered by controlled operation of the vacuum pump 19 in accordance with pressure, and of the pumps 12, 13 in accordance with leakage water level. A cylindrical valve may be arranged around the periphery of the pump or turbine rotor. The residual power loss due to the small amount of air remaining in the evacuated machine causes the remaining air to be heated and consequently the stationary surrounding walls of the machine to be relatively cold. The cold walls prevent misting and keep the remaining air relatively dry. A small amount of water may be injected into the evacuated region to control the residual heating.

Abstract: 1,257,307. Rope descent apparatus. BARROW HEPBURN & GALE Ltd. 25 April, 1969 [16 April, 1968], No. 17897/68. Heading A3V. [Also in Divisions A6, E2 and F2] A device capable of being fitted to a suspended rope R and exercising frictional restraint on the descent of a person having a safety belt (not shown) attached to the device at 2', comprises a runner through which the rope can travel, the runner having a core 1 around which the portion of the rope within the runner cap wrap one or more times, and surfaces 5', 8' between which the rope can pass and which are relatively movable by hand to give a variable grip on the rope during descent. The rope passes through a cut away portion of an end plate 3' clamped to core 1 by an eye bolt 2' which is screwed thereto; the rope passes over roller 5' at one end of a pin 4' extending through core 1, and passes under a stud 8' secured to a plate 7 slidably mounted over the end of pin 4'. The upper end of the device in Fig. 1 is similar to the lower end, and also shows pins 12 which are fitted through the eyenuts 2, 2' and end plates 3, 3' and which cooperate with pins 4, 4' to prevent the end plates rotating. A tubular cover 9 is screwed to plate 7 at 11, so that downward movement of the cover grips the rope between members 5' and 8' and slows descent. As the device is symmetrical it may be used either way up. Alternatively the gripping surfaces may be formed directly by the core and cover.
