A liner is positioned within the upper section over an inner face of the sole section and upper section. The sole and upper sections are molded on a sole plate insert to impart stiffness to the sole section while permitting flexing in the sole along an area transverse to the long axis of the sole section intermediate a front foot and a rear heel portion of the sole to permit the heel portion of the foot to be lifted off a surface while the toe portion of the boot is immovably secured.

Abstract: The invention relates to a system for simultaneously photographing two objects on a single instant film. Such systems are used in, for example financial institutions such as banks for simultaneously photographing a transaction document, such as a cheque, and the person related to the document, such as the person cashing the cheque. In accordance with the present invention, the camera of the system includes two separate lenses, each one receiving light rays bearing the image of a different one of the objects. Associated with each lens is a separate shutter mechanism, and the f opening or the shutter speed of each shutter is separately adjustable by means which are readily accessible to the camera operator. Thus, the shutters can be separately adjusted to take into account the different lighting conditions to which the separate objects are exposed.

Abstract: A box-type rectangular container of sheet material having nesting tray and cover parts having a floor and roof respectively and overlapping sidewalls. A pair of the overlapping walls is cut and creased to provide inside and outside access panels for swinging outwards to reach the contents without opening the container. Optionally, catch means may be provided for retaining the access panels reclosed after they have been opened.

Abstract: The invention relates to an electronic detection and transmission system known in the art as a money clip. Presently available such money clips are pressure sensitive and transmit initiating signals on detection of a decrease in pressure. Such systems have disadvantages, and the present system overcomes certain of the disadvantages by providing a system wherein detection is accomplished by a light sensitive means such as a phototransistor. In accordance with the invention, the electronic circuitry is contained in a housing having a top surface. The phototransistor is disposed below an opening in the top surface, which is preferably centered on the top surface. When the opening is uncovered, light will enter the opening and fall on the phototransistor to activate the phototransistor. The phototransistor is connected in circuit with a transmitter which will similarly be activated to transmit an initiating signal.

Abstract: A method and apparatus are provided for the extrusion of a thermoplastic material in modified form in which the thermoplastic material is introduced into the barrel of a screw extruder, and is heated and forced through the barrel: the material is passed through valve means which together with the temperature of the material is effective to produce a melt transition in the material at a predetermined point and to thoroughly mix the material; subsequently, the material is forced into a low pressure zone in the barrel where a modifying agent is introduced into the material; the resultant mass is forced out of the low pressure zone, and is passed through a mixing means effective to intensify the dispersion of the modifying agent in the mass, the mass is extruded and the extruded material collected.

Abstract: An exhaust stub for a turbo-prop engine which exits from the aircraft nacelle at a location other than the aft end. A fairing is attached to the exhaust stub to minimize frontal area for a given exhaust stub exit area, but free of the nacelle, because of the requirement for the exhaust stub to move relative to the nacelle. An end plate is secured about the exhaust stub and fairing, substantially parallel to and at close proximity to the nacelle. The end plate effectively improves the performance of the fairing, by eliminating the effect of the gap in the nacelle around the stub and also the gap between the fairing and the nacelle. Improving the performance of the fairing reduces the magnitude of the exhaust duct wake which in turn reduces the momentum definiency in the wake flow; reduces exhaust duct drag; reduces mixing of the exhaust gases into the wake region; and reduces nacelle sooting by exhaust gases.

Abstract: An automatic bagging machine for holding and opening a first bag of a plurality of juxtaposed bags held in the machine in a manner whereby the first bag may be filled with a product and detached prior to release of the first bag from the plurality of bags. The bags are of the type having an extended tab secured to a portion thereof and extending above a mouth opening of the bag. The machine comprises a holding device for engaging at least a portion of the extended tab of the first bag. A retractor member is also provided for opening the mouth opening of the first bag by pulling a side wall portion of the first bag opposite to the engaged portion of the tab and away from the engaged tab. The retractor member also clamps the side wall portion to hold the bag in an open position whereby the bag is held from opposed sides for filling the bag with the product.

Abstract: A metal sheet for lining side walls of a freight railway car having a plurality of spaced-apart vertical wall supports. The metal sheet comprises a plurality of spaced-apart elongated channels formed across a flat surface of the sheet. Each of the channels has a bottom wall spaced from the flat surface of the sheet. A plurality of spaced-apart apertures are provided in the bottom wall of at least some of the channels to permit an attachment element to connect the sheet to an associated one of the vertical wall supports. The channels are configured to receive an anchor bar having an attachment part and securable ends. The securable ends are weldable in the channels in close proximity to an associated one of the apertures so that the anchor bar is rigidly connected, through its weld and the bottom wall, in close proximity to the support, whereby cargo retaining strapping, or the like, may be attached to the attachment part to secure cargo in the railway car.

Abstract: This invention relates to an exercising apparatus which is adapted, in use, to provide relief from backaches and to maintain general physical fitness. The apparatus includes a pair of rests on which a person using the apparatus would support himself by his armpits. The rests are retained above a floor level in a spaced parallel arrangement, and they are either suspended from the ceiling by suspension members. The rests are constrained from movement in a longitudinal direction whereas means are provided for permitting the lateral movement of the rests. Disposed on each of the rests for carrying a part of the weight of a person using the apparatus are either hand grip or elbow support members. In use, a person using the apparatus mounts the apparatus in such a manner that his armpits are disposed over the rests. As the rests are movable in the lateral direction, the spacing between the rests can be adjusted to accommodate persons of different girth.

Abstract: The invention relates to an improvement to an installation for preventing the ingress of super-cooled water, ice, snow and other debris as taught in U.S. Pat. No. 3,329,377. In the patent, an inertial separator effect is used to prevent ingress of super cooled water, ice, snow and other debris to an aircraft engine. The effect is obtained by an installation including a duct formed in a sub-nacelle of the engine to extend generally longitudinally of the engine. An air deflecting surface in the duct confines the incoming air to a passage of reduced cross section, and an opening in the duct wall downstream of the deflecting surface is formed between the trailing edge of the deflecting surface and the leading edge of a rearward portion of the duct, the opening in the duct wall communicating with the engine air intake. In accordance with the present invention, any or all of the following improvements are made to the above installation:A.

Abstract: A curing chamber has entry and exit ports for passing articles to be cured therethrough. Air curtains are provided at the inlet and exit ports. Communicating means connect the air curtains to a source for maintaining a pressure equilibrium at the air curtains. Means from outside the air curtains supply a controlled heated moist vapor for providing predetermined moisture to the air curtains to thereby reduce the escape of volatile gases within the curing chamber.
