Abstract: A series of adjoining concentric rings are cut from a metal plate. The same number of hubs, all the same shape, are also cut from plate material as are annular web plates to fit around hubs, but the outer diameters of the web plates are different from one another in order to fit in the different rings. Each web plate is welded to a hub and encircling ring to form a sheave that is then provided with a circumferential groove to provide a grooved rim for receiving a wire line. The sheaves can be mounted side by side on a common shaft, with the largest sheave at one end and the smallest at the opposite end. This arrangement is suitable for a crown block.

Abstract: In gapping a stringer of a slide fastener, a plurality of interlocking elements in a portion to be gapped are gripped, such as by a comb, while the tape is clamped or held, and then relative movement is produced between the gripped fastening elements and the held tape either by moving the gripped elements or the held tape with a pivoted motion to pull the gripped elements seriatim from the tape.

Abstract: A plurality of separate metallized regions on a substrate form a bondsite for a single lead to be bonded to the substrate. The metallized regions are electrically interconnected at a point removed from the bondsite. Such multiple metallized regions offer redundant bonds for each such lead to improve the mechanical strength and to improve the reliability of the bond between the lead and the substrate.

Abstract: A two part shock or vibration mount which comprises an elastomeric member and a metallic member are automatically assembled into an integral one piece unit by feeding the parts on a conveyor in axial juxtaposed relative position into a compressive force device that is mounted above the conveyor at an angle of declination with respect to the conveyed components such that an increasingly progressive compressive force is applied to the juxtaposed components. Upon exiting the force applying device the components are in a force fit engagement one within the other.

Abstract: A snap fastener attaching system employs a moveable carriage assembly which is controlled in linear motion by a belt system coupled to an actuator mechanism. The carriage assembly includes clamping means which are sequentially operated to clamp a garment on the assembly after emplacement by an operator. The depression of a start button enables the actuator to traverse a shaft. Associated with the actuator is a pivotable arm which is located in proximity to a selected shaft of a cam-containing turret assembly. As the actuator moves, the carriage moves proportionately due to the belt coupling system. Each time the actuator arm contacts a cam along the turret shaft, a fastener is emplaced on the garment by the snap fastener attaching machine associated with the carriage assembly. When the last fastener is emplaced, the apparatus is automatically returned to the starting position to enable accommodation of the next garment.

Abstract: Construction elements comprising two parallel nailable plates interconnected by corrugated metallic web sheets extending edgewise between them and having teeth at their edges embedded in the plates are made by placing the bottom plate thereof in a movable frame having displaceable abutments connected to clamping means. The web sheets are placed in positions so as to be clamped at their extremities by clamping said means, the extremities of longitudinal sheets being pinched in folds of transverse end sheets. Also, interlocking deformations are punched in the adjoining webs. The clamping means are moved for stretching the sheets, the upper plate is placed on top, and web sheets and plates are brought into correct relative positions by corresponding positioning of the abutments. In addition longitudinal web sheets extending along edges of the element are supported externally between clamping points by spring-loaded rulers connected to abutments so as to ensure correct spacing from the plate edges.

Abstract: Method and apparatus are disclosed for making integrated optical circuits. A waveguide in the form of a thin layer of dielectric material is modified as to its coherent radiation transmitting properties by electron beam impingement thereon so as to modulate coherent radiation by mode conversion and mode guiding. Preferably the layer is of thermoplastic material which is locally charged by the electron beam and is heated to allow corresponding deformation due to the forces generated by the localized charging. When cooled, the deformations are frozen in but may be erased by subsequent reheating whereafter the deformation process may be repeated, thus allowing reuse of the device for a different optical circuit, or allowing its modification to form a different optical circuit.

Abstract: An electrical jumper cable comprising a plurality of spaced metallic conductors, each conductor having a flexible area and integrally formed rigid terminal ends, is provided. Starting with a metallic sheet having a thickness approximating that required for the conductor flexible areas, one or more mesas of thickness approximating that required for the terminal ends are formed on the edge regions of the sheet. The mesas may be formed by plating or casting so that the thickened edge regions are integral with the sheet central region. The resulting substrate is then chemically or mechanically milled so as to define the conductor patterns and terminal ends, and the metallic conductors laminated to flexible films so as to support and maintain the metallic conductors in spaced relation to one another.

Abstract: An improved method is disclosed for manufacturing a keyswitch assembly which includes a plurality of switches in a predefined arrangement on the face of an insulative circuit board and which also has a protective, insulative coating over the switches and board face. Each of the switches includes a pair of spaced contacts on the board face and a resilient, deformable, electrically conductive actuating element which can be selectively deformed to provide an electrical circuit between the two contacts. The method is performed with the aid of a planar template having a plurality of apertures positioned in a predefined arrangement corresponding to the arrangement of the switches on the circuit board. As an initial step, an insulative sheet, eventually forming the coating, is placed on a flat surface and the template is placed on top of the sheet so that the sheet is sandwiched between the template and the surface.

Abstract: Apparatus and method for gear tooth alignment by accommodation in more than one stage gear cluster assembly. This arrangement essentially isolates the mass of one gear member in a cluster assembly from that of the other and makes the effective mass at the gear mesh to be equal to or less than that of a gear on either end of the gear shaft with respect to its connected masses. This permits a design for extremely high power ratio for a gear train by isolating inertias of the elements and reducing dynamic loads and forming a torsionally soft shaft to allow alignment of the gear teeth by accommodation by allowing the unbalanced load in between the gears to enable the gears to mesh together.

Abstract: A method for manufacture of bag-like toy constructions assembled from individual vinyl panels. Designs, comprising the artwork on each individual panel, are printed continuously on vinyl sheets in precisely reproducible and spaced sequence. Each vinyl sheet has indexing and registration marks printed along opposed edges. After printing, a plurality of said vinyl sheets are stacked and fastened together in registered alignment. Templates are then utilized to outline each individual panel on the uppermost vinyl sheet. A cutting tool is then used to cut all sheets simultaneously along the template lines. The resulting panels are then seamed together with the printed design face of each panel facing outward, forming a completed toy construction.
