Abstract: A scrubbing-brush is manufactured by the following process. First, a number of nets formed of fibers connected with one another are secured. The bundle is bundled at an intermediate portion thereof by a bundling member. Then, the bundle is cut at opposite sides of the bundling member. The thus cut bundle is then heated to cause memory deformation of the fibers, thus completing a scrubbing-brush. The thus finished scrubbing-brush has a number of fibers having respective ends formed with smooth convex bristle surfaces.
Abstract: Frequency-modulated electrical signal generator comprising two oscillators, the first delivering a modulated output frequency and driving a mixer which receives in addition the output of the second oscillator. The latter is phase-controlled by a loop comprising the mixer, a filter and a first phase comparator which receives an intermediate frequency. The first oscillator is controlled by a loop including the second oscillator followed by an adjustable frequency divider and a second comparator receiving a reference frequency.
Abstract: An injection molding machine has a fixed and a tool portion, a shroud mounted for sliding movement around and in sealing relation to one of said portions towards and into sealing engagement with the other portion so as to define with the portions a substantially closed chamber around a molding tool associated with said portions together with means operable to urge said shroud into said sealing engagement and means for at least partially evacuating the closed chamber.
Abstract: A method of manufacturing collectively stranded wires for communication cables, comprising a process wherein parallel multi-wire sets obtained by the extrusion method from insulating material and a plurality (2, 3 or 4) of conductor wires arranged in parallel are prepared in such a way that said multi-wire sets are different in color from each other and the number thereof corresponds to that of the conductor wires included in each thereof, and said multi-wire sets are drawn out and separated into element wires which are, after given pre-twisting, sorted into groups each consisting of wires of different colors coming from the corresponding sets and then are wound on bobbins, a process in which said bobbins prepared according to desired number of stranded wires to be collected are mounted on delivery stations of stranding machines through which the wires are stranded and sent out as pairs, 3-conductor or 4-conductor wires, and a process wherein desired number of said stranded wires are collected.
Abstract: This device incorporated in a release or ejector mechanism for adjusting the transverse direction of an airborne load comprises a device for pivoting thereon the load-supporting hook and a bell crank linkage system, whether the load is equipped with a so-called saddle member or with standard rings. This device comprises essentially a cylindrical body formed either with an eccentric portion or with a transverse screw for performing the necessary adjustment, and a lock nut for firmly maintaining the selected adjustment position.
Abstract: Apparatus for use with a food slicer comprising a conveyor for location adjacent to the said slicer and adapted to receive slices of food as they are cut by the slicer; a pump for generating hydraulic pressure, a motor driven by said hydraulic pressure; passageways between said pump and said motor; means for drivingly connecting said motor to said conveyor; a flow limiting valve in the passageway between the pump and the motor for limiting the speed at which the said motor drives said conveyor; and means for periodically increasing the fluid flow to the motor temporarily to accelerate said motor.
Abstract: An electrical appliance in which flexible conductors connect the terminals of the plug to the terminals of the body, the plug being divided into elements capable of being separated in order to facilitate soldering and then reassembled on installation, the arrangement being advantageous for small devices such as relays.
Abstract: In operation of an internal combustion engine, a lamina of air is introduced into the combustion chamber to line the wall thereof, the fuel being admitted into the interior of the lamina of air. In a two-stroke engine, air entering the combustion chamber is driven by the incoming fuel mixture to form a lamina which lines the wall of the combustion chamber.
Abstract: The automatic stopping device for use in a tape recorder comprises a detection arm mechanically operated in response to stopping of the rotation of a reel driving shaft. A flywheel connected to a capstan is provided with a plurality of projections arranged about the capstan to be engaged by a latch member. A push lever is pivotally connected to the latch member and a stationary deck. The push lever and the detection lever are interconnected by a connecting lever and a spring through slot means.
Abstract: A pneumatic apparatus for the rotation of a valve rod having a box-design body with a cylindrical seat, on the inner wall of which there is disposed a static resilient gasket, shaped so as to convert the said cylindrical seat to an almost 8-shaped configuration. In this manner, the cylindrical seat is divided into two half-chambers communicating with each other and each of them communicating with the inside, through cross tubular lines.
Abstract: A tuning fork-type piezoelectric vibrator having electrodes for the excitation formed on the legs of the vibrator body which electrodes extend for at most subsequently half the length of said leg reveals a powerful suppression of the vibration modes of higher orders and substantially no increase in the series resonant impedance in the vibration modes of fundamental frequency.
Abstract: This device for jettisoning a load in two completely different ways comprises a rocker fulcrumed on a support rigid with the load, or spherical member formed integrally with the support, and a pair of opposed hooks fulcrumed to the structure from which the load is to be suspended, these hooks being responsive to separate control members, so that when only one hook is retracted the load can be released. If a spherical member is used, sliding cylindrical members having opposed ends formed with spherical concavities matching the curvature of the spherical member are provided, so that retracting one or both sliding members will release the load.
Abstract: The invention relates to an apparatus for internal measurement of the exposure in photographic cameras where the light penetrating the picture-taking or objective lens is fed by way of a mirror to a photoelectric cell.A marginal reflective surface faces the objective lens and surrounds a picture window adjacent the film surface. The marginal surface is formed as a concave mirror the optical axis of which is inclined to the optical axis of the objective lens so as to reflect part of the light therefrom to the photoelectric cell.

Abstract: A portable artificial respiration device of lightweight construction for use in operations and for resuscitation. A housing includes an inlet for receiving a respirator fluid under pressure, a conduit for communicating with a patients respiratory system and an outlet for communication with the atmosphere. A rotatable distributor valve within the housing comprises a tubular member having an opening at one end which continuously communicates with the conduit. An opening in the wall of the tubular member when rotated to be adjacent the inlet provides a path for the respirator fluid to the patient for inspiration and when positioned adjacent the outlet provides an expiration path from the patient to the atmosphere. A variable speed drive under electronic speed control rotates the member to determine the inspiration and expiration rate of the patient when coupled to the device.
