Abstract: The invention relates to a device for locking doors of machines containing rotating members which closes the contacts of an electrical switch subsequent to locking the door and opens the contacts prior to unlocking the door. 
     It is characterized by the fact that hook 5 of the door is retained by a block 4 which is rotated about its axis due to the action of hook 5 while closing the door so that after the locking of the rotating block 4, hook 5 can no longer be drawn out. Rotating block 4 is fixed on a small shaft 3 with which it rotates, said small shaft 3 having in turn a second substantially cylindrical block 7 which has a peripheral surface shaped as a cam and which has in the end opposite the first block 4 a cavity 8 to house the tail 27 of a locking bolt 9 which moves parallel to the axis of said small shaft 3, the opposite end 26 of locking bolt 9 working on the moving contact 10 of the electrical switch 11. When the end of locking bolt 27 enters the cavity 8 it locks block 7 and therefore block 4 against rotation, thereby locking the door. The operation of the various parts of the device is obtained by means of two mobile boxes moving parallel to the axis of the shaft 3, of which one 14 cooperates with cam 7 arranged on shaft 3 and the other 13 cooperates with the front part 29 of locking bolt 9 and with a lever arm 19 rotating about a pivot 20 with the opposite end connected to a small piston 22 of an electromagnet 23.

Abstract: The present invention relates to a method for controlling the heating water circulation in a gas-fired water heater, consisting of at least one heat exchanger (2, 3) which is heated by a burner (1) and to which a heating water forward run pipe (8) with a temperature sensor (9) for forward run temperature regulation and a heating water return run pipe (7), in which there is a heating water circulating pump (6), are connected, the forward run temperature T2 being constantly controlled, and compared with a maximum forward run temperature Tmax stored in a regulating device (15) which is line-connected to an automatic firing machine (14) and the burner (1) being switched off in the event that this temperature is exceeded. In order to guarantee reliable switching off in the event of low water, it is envisaged according to the invention that the heating water temperature is measured at an additional point approximately in the centre between forward and return run pipe (7, 8) and the temperature difference  DELTA  T between the forward run temperature T2 and this heating water temperature T1 is determined. This temperature difference  DELTA  T is compared with a maximum temperature difference  DELTA Tmax and a minimum temperature difference  DELTA  Tmin stored in the regulating device (15) and this temperature difference  DELTA  T is used as second switch-off criterion  DELTA  T <  DELTA  Tmin, in addition to the first switch-off criterion T2 - T1 >  DELTA  Tmax. <IMAGE>

Abstract: The rolling socle has a rectangular frame which is provided on each side with a number of rollers (7-10). The rollers are combined in groups (I, II) so that at least two rollers (7, 8; 9, 10) are present in each group. When a bottom cross-groove (21) is crossed, the roller located in the region of the cross-groove is relieved by the associated roller of the same group, so that cross-grooves can be crossed without difficulty. Several rolling socles of different sizes are constructed in such a manner that, in the case of each rolling socle, the distance between two selected rollers allocated to different groups corresponds to a predetermined value (a) which coincides with the distance between the chains (17, 18) of a chain conveyor for transverse displacement of the rolling socles. <IMAGE>

Filed: 1989-11-03
Abstract: The Prothrombin Time (PT) is used as a screening test for blood coagulation factor deficiencies and for monitoring oral anti-coagulant therapy using coumadin. Thromboplastin reagents activate the extrinsic pathway of coagulation and are the basis for the Prothrombin Time (PT) test. This invention describes the use of barium sulfate and chaotropic agents, and nonionic detergents, for the extraction of sensitive thromboplastin reagents from tissue. Extraction with sodium thiocyanate alone also greatly enhances thromboplastin sensitivity. This invention should be useful for all thromboplastins and will improve their sensitivity for all PT-based tests and specific assays.
