Abstract: Weighing apparatus for indicating weight which includes a scale for body weight, a calorie scale carried by the body weight scale, standard weight setting scale coordinated with the calorie scale so that a calorie intake will be indicated to lower or raise the body weight to bring it to the standard weight and an exercise scale for indicating amount of exercise and coordinated with the calorie scale to modify the calorie intake in accordance with the calories utilized as a result of the exercise.

Abstract: A method and apparatus for feeding material intermittently discharged from one machine, primarily an injection molding machine, to another machine, primarily a granulator mill. The feeding-in operation offers low energy consumption, great flexibility as regards material particle size and discharge rate for the grinding material, as well as minimal hazard risk. A predetermined amount of material is collected in a receiving compartment whereafter the collected material amount is moved along a supply path into the granulator mill by means of one or more currents of driving gas which flow through the receiving compartment and are led off from the supply path before reaching the granulator mill itself. The driving gas which is discharged intermittently only during the actual feeding cycle also opens a pivotal flap disposed in the supply path and preventing goods being subjected to grinding from being flung out of the granulator mill.

Abstract: An optical smoke detector which includes a light source and light sensing element so arranged that the quantity of light detected by the element will be determined by the presence of smoke in the detector, a power source for periodically supplying sets of actuating pulses to the light source, apparatus connected with the light sensing element for detecting light pulses which are synchronized with the actuating pulses and producing an alarm when pulses of a predetermined magnitude are detected.

Abstract: An eye examining device having a television camera and monitor connected thereto, an optical system for magnifying the eye ground or retina and focussing the image on the camera, a cathode ray tube connected with the camera and scanned in synchronism therewith, a light pattern generator connected with the cathode ray tube and monitor for display thereof and an optical system for projecting the image on the cathode ray tube onto the eye ground.

Abstract: Driving means for agitators and other devices having vertically disposed driven shafts which includes an intermediate shaft carried by bearings capable of withstanding thrust and radial loads, a coupling connecting the driven shaft to the lower end of said intermediate shaft, a coupling on the upper end of the intermediate shaft and a drive motor having a downwardly extending driven shaft engaging the coupling on the upper end of the intermediate shaft and a mounting for said motor to permit displacement thereof in a plane normal to said intermediate shaft.

Abstract: The drilling fluid of deviant composition is subjected to a separating process comprising two stages, including a sieving stage and thereafter a pressure filtration stage, the drilling fluid clinging to the sieve residue obtained in the sieving stage is sucked off by means of a partial-vacuum, the liquid obtained in the separating stage is used for adjusting the desired composition of the drilling fluid in the supply container thereof, and the solid material separated in the separating process is dried and further processed for recovering the solid material to be used in the drilling fluid.

Abstract: A mist generator for producing mists having uniformly fine particles which includes a housing having a base, a nozzle extending upwardly therefrom and a compressed gas inlet coupled to the nozzle and a cooperating structure disposed within the housing and engaging the nozzle, the cooperating structure having a plurality of successive chambers which function with the nozzle to aspirate a liquid retained in the base to form a mist and then effect agitation of the mist and, discharge it in a downward direction within the housing and an outlet on said housing for discharging the mist.
