Abstract: Case 2710 SELF-ADJUSTING BRAKE ENGINE   LIMIT SWITCH ASSEMBLY           ABSTRACT OF THE DISCLOSURE      Previously limit switch assemblies for friction mine hoist brake engines were fixed to a mounting bracket.  The assembly usually had two spaced apart facing microswitches with an operating arm or actuator extending between them.  When the brakes were released the actuator would move outwardly to operate one switch providing an indication that the brakes had released and were not dragging.  When the brakes were applied the actuator would move inwardly to a brake applied position but not far enough to operate the other switch until such time as the brake linings were worn enough to require brake adjustment at which time the other switch would operate.  When the brake engine was first set up the position of the actuator at brake release and brake applying conditions was not known and shimming was required to place the switches in the correct position.  If the position was not correct the switches could be smashed.  The self-adjusting limit switch assembly of this invention has the two switches mounted on a slide for sliding movement on a bracket.  A transverse slot in the slide has two facing surfaces.  The switches are mounted on each side of the slot with their operating members extending slightly past the slot.  The actuator is positioned to extend into the slot.  When the brakes are first moved to the brake released position the actuator engages not only the operating member of the switch on that side, but also a wall of the slot and moves the slide to a brake released position thereby correctly adjusting the position of the switches.  When the brakes require adjustment due to wear, the actuator engages the operating member of the second switch, as before, causing an indicator to function.

Abstract: ABSTRACT OF THE DISCLOSURE         An improved method is provided for detecting endotoxins in blood serum and/or plasma, particularly human blood fractions.         The method employs king crab amebocyte lysate, preferably Limulus amebocyte lysate, in the presence of a substrate which has a selected colorimetric indicator bound to it.  The indicator is capable of being split from the substrate by an enzyme which can be generated in the lysate by endotoxins in the blood.  Thus, the endotoxins convert proenzyme in the lysate to the enzyme which effects the splitting off of the colorimetric indicator from the substrate.  The endotoxin concentration in the blood can thus be determined calorimetrically, that concentration being proportional to the concentration of color indicator split from the substrate.  The blood sample need not be extracted, as is required in prior methods, with a solvent such as chloroform to remove inhibitors therein which would interfere with a lysate gelation reaction.  Heparin is utilized in the present method in a concentration sufficient to stabilize the lysate against loss of potency but insufficient to inhibit the reaction whereby endotoxin generates the described splitting enzyme from proenzyme in the lysate and the reaction of the enzyme to cause the split.         The blood fraction need not be diluted with water and the lysate may be one which has been reconstituted from dry powder, if desired.  The method is simple, highly effective, reproducible, inexpensive and rapid.

Abstract: 49,581I ABSTRACT OF THE DISCLOSURE Lightweight, transistorized, inverter circuit is particularly adapted for starting and operating screw-in compact fluorescent lamp intended for incandescent lamp replacement.  Household-type AC is converted to DC with one terminal connected to the center tap of a transformer primary through a choke which constitutes a high impedance at the operating frequency.  A tuned circuit capacitor is connected across the transformer primary and a current-limiting capacitor and the lamp to be operated are con-nected in series across the transformer primary.  A pair of  transistors  are  connected  in  push-pull  arrangement between the end portions of the transformer primary and the other terminal of the DC source, with the base members of the transistors connected to the transformer secondary winding so that the push-pull connected transistors oscil-late  at the  tuned circuit  resonant  frequency which is determined by the inductance of the transformer primary winding and the total capacitance of the connected capac-itor means.  A potential is applied to the midpoint of the transformer secondary upon energization of the apparatus in order to initiate transistor conduction.  The apparatus is lightweight and efficient and the system operates with a high efficacy for the production of light.

Abstract: BACKGROUND OF THE INVENTION   1. Field of the Invention The present invention is directed to a vacuum cleaner tool for use in a household, office or light industrial environment for cleaning carpets, floors, walls, and other vertical and horizontal surfaces, draperies, upholstery, etc. and, in particular, to a vacuum cleaner tool which has an opening therein and a swivel mechanism which enables the user to vacuum perpendicular surfaces without changing the orien-tation of the wand, hose or the like, which couples the tool to the vacuum cleaner. Further, the present invention is directed to a vacuum cleaner tool having an air-powered turbine motor for driving an agitator device, such as a brush, which extends from the housing and, in particular, to a vacuum cleaner tool having an agitator brush extending from the housing in which the housing has a removable wall portion which incorporates an air nozzle for the air turbine and which, when removed, allows access to the turbine and brush for the removal of large particles which may be obstructing the tool.   2. Description of the Prior Art The use of a vacuum cleaner tool to vacuum steps has been a problem in the past because the step contains two perpen-dicular surfaces, the horizontal tread portion and the vertical the separate compartment within the housing, and the pulley and drive belt compartment is sealed from the portion of the housing containing the turbine motor in order to prevent leaks and enhance the efficiency of the turbine motor. The agitator is enclosed within an agitator enclosure portion of the housing, and the housing further includes a removable wall portion which has an air nozzle positioned thereon. The air nozzle extends from the agitator enclosure portion to the turbine chamber of the turbine motor, and forms at least a portion of the peripheral wall of the turbine chamber. The nozzle directs air from the agitator enclosure into the turbine motor.
