Abstract: A latent heat accumulator is disclosed including a vessel for receiving a tent heat storage medium and a circuit for a heat exchanger medium. The heat exchanger medium is immiscible with the latent heat storage medium, has a different density than the heat storage medium and is openly conveyed through the heat storage medium. The vessel contains a collecting chamber for the heat exchanger medium and has a heat exchanger arranged therein. An external heat carrier medium flows through the heat exchanger for transfer of heat between the heat carrier medium and the heat exchange medium. The accumulator is characterized in that a first heat carrier medium for adding heat and a second heat carrier medium for withdrawing heat are conveyed in the heat exchanger in separate conduit systems which are in heat-conductive contact with each other and with the surrounding heat exchanger medium.

Abstract: A differential apparatus is disclosed of the type including pairs of helical differential pinions for transmitting torque from a rotatably driven differential carrier housing to a pair of side gears splined to a pair output shafts, respectively, characterized by the provision of a collapsible and expansible wedge block spacer assembly for maintaining the output shafts in spaced relation and for reacting to axially inwardly directed thrust forces. During assembly of the differential apparatus, the spacer block is introduced, when in a collapsed condition, into the housing via a transverse access opening, to a position between the output shafts, whereupon the wedge block assembly is axially expanded into supporting engagement with the adjacent ends of the output shafts. The housing includes three sections, a pair of end cover sections being arranged on opposite sides of a center section of contoured configuration.

Abstract: An end closure member is disclosed for closing the bottom of an institutional-size composite container for frozen liquid or fluent materials (such as eggs removed from the shell), characterized in that the end closure member includes a center panel portion, an annular rim portion, and a vertical intermediate tubular portion that connects the center panel portion with, and at a lower elevation than, the rim portion, whereby during the subsequent freezing of the product within the container, the freezing progresses upwardly from the central panel portion, thereby relieving stress on the connection between the bottom end member and the composite body wall. The bottom end closure member includes a stacking rib adapted for insertion within a corresponding stacking recess contained within the container upper closure member.

Abstract: An improved flexible container structure is disclosed in which there is woven in selected areas of a base fabric formed of body yarns threads of reinforcing yarns extending in the intended load-bearing direction. Preferably, the tension of the reinforcing yarns during weaving is greater than the tension of the body yarns in the load-bearing direction.

Abstract: This invention relates to weighing apparatus of the electromagnetic load compensation type including a load or compensation coil connected with the load receiving member, and a reference coil connected with the frame for movement independent of the load receiving member, characterized in that the load and reference coils are arranged within separate air gaps of the magnetic field produced by a permanent magnet system mounted on the weighing apparatus frame. In one embodiment, the permanent magnet system includes a permanent magnet having a rotationally symmetrical field, and a magnetic yoke arrangement including an annular outer pole shoe arranged in concentrically spaced relation about an inner pole shoe. An annular ferromagnetic member is arranged in concentrically spaced relation between the inner and outer pole shoes for defining the air gaps in which the reference and load coils are arranged, respectively.

Abstract: A specimen testing apparatus is disclosed, including a sensing device for engaging a specimen mounted on a support, an electrical measuring system associated with the sensing device for producing an electrical signal that is a function of a variation in a physical characteristic of the specimen as determined by the sensing device, and an electromagnetic compensation system for applying a compensating force to the sensing device. In one operating condition (as, for example, when the thermal expansion properties of the specimen are being tested), the compensation system is operable to apply to the sensing device a force compensating for the weight of the sensing device, thereby to cause the sensing device to rest upon the specimen in a weightless force-free manner. Alternately, the compensation system may be operable to apply to the sensing device a supplemental force in the compressive stressing condition, as might be desired when penetration tests are to be conducted on the specimen.

Abstract: A non-silver scored metal end closure member, and an apparatus and method for forming the same, are disclosed, characterized by the provision of a continuous scoreline between the radius and central panel portions of the end. The scoreline includes, in cross-sectional profile, a horizontal flat bottom wall, and outwardly divergent outer and inner side walls. In the preferred embodiment of the invention, the scoreline is contained in the upper horizontal surface of the metal end, the other side wall of the scoreline being concave and having a radius less than that of the radius portion of the metal end, the bottom wall being tangent to the outer side wall. The inner side wall comprises either a flat surface arranged at an obtuse angle of about 165.degree. relative to the bottom wall, or a concave surface tangent to the bottom wall. In another modification, the inner side wall is concave and tangent to the bottom wall, the radius of the inner side wall being at least as great as that of the outer side wall.

Abstract: A forward converter circuit (FIG. 1) is provided with a transformer reset sensing circuit (FIG. 2) whereby base drive to the switching transistor TR1 is inhibited until after reset of the transformer T1. The reset sensing circuit includes a sensing winding T1d provided on the transformer for sensing the waveform at the primary winding T1a, a comparator IC1 and diodes D5, D4 connected in such a way that one input of the comparator is high when the waveform changes in one direction, and the other input of the comparator is high when the waveform changes in the other direction. The output of the comparator inhibits switching of the transistor before reset and thus allows the use of a maximum switching duty cycle of 50% without risk of transformer saturation.

Abstract: A composite container is disclosed having a synthetic plastic end closure member spin-bonded to the thermoplastic synthetic plastic inner liner layer of a composite container body wall. The synthetic plastic end closure member includes annular downwardly depending inner fin and outer chime portions which are concentrically spaced to define therebetween an annular groove. One of the body and end members is rotated relative to the other member when they are in spaced vertical alignment, whereupon the members are axially displaced together to wedge the upper end of the body member into the annular groove of the end closure member. During this spin bonding process, the fin portion of the end closure member is supported against radial inward deflection, whereby the spinning frictional engagement between the fin portion of the end closure member and the inner liner layer of the body member causes softening and subsequent bonding of the fin portion to the inner liner layer.

Abstract: A temperature responsive device, such as a fuse or a temperature measuring apparatus, is disclosed including a temperature sensor having a light reflective (or light transmissive) characteristic which varies with temperature, and a device for receiving the light reflected from (or transmitted through) the sensor and to provide an output in accordance with the state of the characteristic. As shown, the sensor (perhaps an adhesive temperature indicator) is used as a fuse and, upon its color-change, it interrupts a switch 2 connecting a power source to a load the temperature of which the sensor senses.

Abstract: An improved brake lever assembly of the overcenter toggle type is disclosed, wherein the brake operating lever is preferably pivotally connected with the stationary mounting plate assembly about a pivot axis that is laterally displaced from the linear axis of travel of an inner cable member relative to the concentrically arranged tubular outer sheath, thereby to reduce wear of the inner cable guide means. According to an important feature of the invention, an improved anchor plate arrangement is provided for connecting one end of the outer sheath member with one end of the stationary mounting plate assembly.

Abstract: Apparatus for producing spark ignition of an internal combustion engine in which sparks at the spark plugs are initiated by a high voltage pulse of typically 20 KV and are sustained thereafter by a d.c. voltage of typically 3 KV. In one embodiment the d.c. voltage is produced from a 12 volt supply by a d.c. to d.c. converter, the converter being adapted to produce a substantially constant voltage irrespective of the current drain produced by the spark, within given limits. The converter is also adapted to shut down its operation in the event of an output short circuit. The converter is disclosed connected to a lean burn PROCO engine with the result that only one spark plug per cylinder is required. In an alternative embodiment the d.c. sustaining voltage is derived directly from a conventional alternator driven by the engine.

Abstract: An improved weighing apparatus of the electromagnetic load compensation type is disclosed, characterized by the provision of a stationary permanent magnet system including two oppositely arranged pairs of spaced parallel flat magnet members that cooperate to define a common air gap. The compensation current coil, which is connected for movement with the movable load-receiving member, is of a flat annular configuration and is contained in the plane of the air gap extending between the magnet members of each pair. The magnet members of one pair are magnetized oppositely from those of the other pair, whereby the magnetic field established across the portion of the air gap between the permanent magnet members of one pair is of a direction opposite that established between the permanent magnet members of the other pair. Consequently, not only can the compensation current for a desired compensation force effect be reduced, but also, the manufacture of the permanent magnet system is greatly simplified.

Abstract: An electrolysis apparatus is disclosed and comprises a plurality of cells connected in series both on the current flow path (an electrical course being connected across the end ones of the electrodes) and the electrolyte/gas flow path (electrolyte entering one end cell through one end electrode and gas issuing from the other end cell through the other end electrode), the cells including at least one series of gas generating cells followed by at least one cooling cell. The end electrodes of a series of cells may be short circuited so that these cells become cooling cells because they are not active to generate gas and instead the electrolyte and gas flowing through them undergoes cooling. The apparatus may be arranged for generating detonating gas or may be modified for generating oxygen and hydrogen at separate outlets.

Abstract: A disc is centered and secured on a shaft by means of flexible webs which extend parallel to the shaft and lie against the inner surface of a central aperture in the disc, and by radially extending tongues fixed to the shaft and entering into corresponding radial slots in the disc. As the assembly rotates, the webs are urged outwards by centrifugal force, to apply a radial compression force to the material of the disc.
