Abstract: Within a bag for vacuum packaging of articles there is created, by means of a separately attached sheet, an auxiliary chamber which is evacuated when the bag is manufactured. This chamber may be placed in communication with the interior of the bag, after the latter has been filled and sealed. Such communication is achieved by piercing or tearing the separately attached sheet, so that the residual air in the sealed bag expands into a greater volume in which it is isolated from the product in the bag.

Abstract: Castings are produced by sandwiching a central mould part 10 between two outer mould parts 36, 38 during the casting process. The central mould part 10 is then transfered sequentially from between the outer mould parts 36, 38 and subsequently re-located between the outer mould parts in a vacant, relatively cool, and dry condition for the production of a further casting. In one embodiment a plurality of central mould parts are transferred sequentially from the outer mould parts to a removal station 45, a quenching station 50, and a drying station 70, before being returned to the central mould parts.

Abstract: A sensor for capacitively measuring the level of material in a container where the sensor extends through an opening in the container and is connected to measuring circuitry. The sensor includes an electrically conductive, tubular member aligned with the opening. An elongated electrically conductive member is in electrical contact with the circuitry and projects through the container opening and the tubular member such that a space is established between the elongated conductive member and the tubular member so that they are electrically insulated from one another. The space is sealed to prevent entry of moisture therein.

Abstract: A toggle clamp having first and second clamping members pivotally connected together for receiving objects to be clamped therebetween; a handle pivotally mounted with respect to one of the clamping members; a bail including a force generating member where the bail is so mounted with respect to the handle that upon movement of the handle from a first position to a second position, the force generating member is moved to a first position to generate a force for clamping the objects together with a first clamping force; and, a member, upon weakening or failure of the force generating means, which permits movement of the force generating member to a second position where the objects remain clamped together with a force less than that of the first clamping force whereby a fail-safe operation is provided.

Abstract: A focusing control for a camera which uses a reflected beam of light to control extension of the lens. The reflected light beam is received by a photodetector having two aligned photodetectors which are movable with the camera lens. The circuitry controlling the lens movement processes the photo-detector signal by producing integrated sum and differences signals from the two detectors and using these signals to provide indications of the direction and amount of extension of the lens necessary to be in focus. The processor uses comparators, a counter for measuring extension and a memory for remembering the direction of misfocus.

Abstract: A plastics container has a side wall and a rim portion moulded in one piece with the side wall. The rim portion is joined to the side wall by an integral hinge portion on which it can be folded inwardly of the container. Thereby a container having an inwardly projecting rim or retaining tabs can be readily produced as a one-piece moulding. Preferably, the side wall and rim portion are inwardly concave, whereby the rim portion can be held in its inwards position by forces caused by folding.

Abstract: A current mirror circuit comprising:a reference current source; a diode fed with a reference current by the reference current source; a plurality of output transistors commonly biased in base-emitter by a voltage induced across the diode and having loads at respective collectors thereof; and load adjustment transistors disposed between the collector of the respective output transistor and the associated load and biased in the respective base by a common voltage, whereby a plurality of output currents having the same value are obtained in respective loads.

Abstract: Fishing tackle including a casting float comprising two members. The first member constitutes a bobber portion. The second constitute a line storage drum. The two members are telescopically moveable relative to each other. During casting the relative movement actuates the release of fishing line from the line storage drum, prior to the float hitting the water.

Abstract: An automotive driving control system comprises a stepless transmission provided between the engine and the driving wheels, a transmission controller for controlling the transmission ratio of the stepless transmission, a throttle valve driver for driving the throttle valve of the engine, an operating state detector for detecting a particular operating state of the engine such as "knock" or resonance with the vehicle body, and a controller for controlling the transmission controller and the throttle valve driver. The controller controls the transmission controller and the throttle valve driver to respectively control the transmission ratio of the stepless transmission and the opening degree of the throttle valve so as to obtain that engine output which corresponds to the amount of depression of the acceleration pedal.

Abstract: Electric heater assembly for use typically with hand-held soldering or desoldering devices includes an elongated resistance element formed from a thin flat metal foil having three connected areas of different resistance, the differing resistance being caused by the different widths of the areas. The first area, to which terminals are attached, is the widest and acts as a heat sink. The second area decreases in width to the first area and acts as a transition area between the first and third areas. The first and second areas include first and second separated portions for providing electrical current to the first area and returning it therefrom. The first area includes first and second strips respectively connected to the first and second portions of the second area. The strips extend adjacent a first side edge of the third area in a side-by-side relationship to the distal end of the resistance element and then back towards the second area to a position where they are connected to one another.

Abstract: A flexible bag-like container holding contents is placed on a setting table. The setting table is provided with an extracting gear and is movable with respect to a housing between a bag placing position and an extracting position. The housing is provided with an extracting gear which is adapted to be engaged with the extracting gear of the setting table when the setting table is moved to the extracting position. Said flexible bag-like container is placed on the setting table when the table is in the bag placing position, and the setting table is moved to the extracting position with the bag thereon so that a portion of the bag near one end thereof is pinched between the extracting gears. A portion of the bag near the other end is severed in response to the movement of the setting table to the extracting position, and then the extracting gears are rotated to move the bag away from the contents.
