Abstract: A vacuum lifting device is attachable to a crane and operates to lift and subsequently release a sheet of material. The device comprises a support assembly including an eyebolt at its upper end for attachment to the hook, a threaded rod and a coupling nut securing the eyebolt and rod together. The lower end of the rod is connected to a vacuum pad. A cover member is fixedly secured to the eyebolt by entrapment between the coupling nut and the eyebolt to provide a protective housing. A vacuum pump is mounted within the housing. In operation, with the device resting on the sheet and with the vacuum release valve closed, actuation of the motor switch starts the motor and vacuum pump so as to create a vacuum in the vacuum chamber whereby the sheet adheres to the vacuum pad.

Abstract: A water closet is disclosed having a bowl with rim wash outlets and a tank connected thereto containing flushing water at a level where most of the water will not flow by gravity through the bowl rim outlets. A tank water withdrawing device is mounted in the tank and is automatically activated when flushing is initiated to withdraw water from the tank and direct it to the bowl rim outlet to supplement the volume of water flowing from a water supply inlet connected to the tank to conserve water usage and provide proper rim wash at low water supply pressure.

Abstract: A moving animal toy wherein when a motor is started upper and lower beaks are pivoted up and down simultaneously to widely open and close its beaks, and at the same time a head is slowly rotated twisting its head sideways. When a voice is uttered against the toy, it is received through a microphone by a voice recording and reproducing device and after a specified recording time elapses, the voice is reproduced by the speaker.

Abstract: A variable pipette is disclosed which is so designed that its volumetric capacity for sucking and discharging a sample is variable. A first-stage stroke l.sub.1 for sucking and discharging a sample is defined between a first first-stage stop portion of a nut and a second first-stage stop portion of an actuating shaft, and this stroke l.sub.1 is set through the actuating shaft, a first stop portion of a threaded hollow shaft, the hollow shaft and the nut, not through any portion of the body of the pipette. Therefore, even if the temperature of the body is raised by the heat transmitted from the operator's hand as it grips the pipette and the body is thereby expanded axially, the above-described stroke l.sub.1 is independent of the expansion of the body and there is therefore hardly any error produced in the stroke l.sub.1.

Abstract: It is intended for measuring a given characteristic of a fluid medium and comprises at least one assembly having an appropriate reagent for said measurement and serving to interact with the fluid medium, reagent support means, an optical fibre (2) called the emitting fibre and used for transmitting light in the direction of the support means and at least one other optical fibre (4), called the receiving fibre and which recovers at least part of the light from the support means when the latter receive the light from the emitting fibre. The support means comprise a single porous or adsorbant element (10) to which is fixed the reagent and which is positioned facing the emitting fibre and each receiving fibre. This element is in direct contact with the fluid medium when the transducer is immersed in it and therefore has no confinement membrane.

Abstract: An oil separator operates to remove oil entrained in a refrigerant being circulated in a refrigeration system, especially a system using a screw-type compressor. The oil separator generally comprises a vessel having a chamber therein and a perforated plate on which oil coalescing elements are mounted divides the chamber into a lower primary oil separator section and an upper secondary oil separator section. A mixture inlet pipe extends through a side of the tank into the lower section for admitting a pressurized mixture of refrigerant and oil. A refrigerant gas outlet port is provided in the upper section for expelling refrigerant from which the oil has been separated. An oil outlet port is provided in the lower section for expelling oil collected in an oil sump at the bottom of the lower section.

Abstract: A ball joint wherein a global head of a ball stud is covered with a bearing seat made of a hard synthetic resin so that the global head is movable in the bearing seat, a shank formed integral with the ball stud is projected from the global head, the bearing seat with the ball stud is pressed into a housing having openings at both ends, so that the shank of the ball stud is projected out of the opening at one end of the housing, engagement portions at both ends of the bearing seat are brought into engagement with the corresponding ends of the housing, and at least one of the engagement portions of the bearing seat is heated and caulked over the corresponding end of the housing to securely fix the bearing seat to the housing.

Abstract: An advertising display including a simulated winged butterfly, bee or the like, and which is rotatably driven by a battery operated electromotor to simulate the flight of a butterfly and draw the customer's attention to the merchandise displayed therewith. The rotatable display includes a thin piano wire on which the butterfly is mounted at the upper end of the wire, the lower end of the wire being secured to a rotatably driven member in such a manner as to preclude breakage due to the repeated flexing. An upper end portion of the wire is bent so that the butterfly trails in the direction of rotation of the driven member and produces a particularly lifelike, articulated and swinging movement of the butterfly.
