Abstract: Cassette for an endless type cinefilm comprises a casing containing therein the film coiled to form windings thereof supported and guided between outer and inner guide rings. The casing has a film gate across which a portion of the film pulled out of the innermost winding of the windings of the film through the outlet cut-out portion of the inner guide ring is moved for the projection or the exposure of the film. After having moved across the film gate, the film is advanced into the inlet cut-out portion of the outer guide ring to merge into the outermost winding of the windings of the film. The casing is provided with an arcuate guide member for the film located outside of the outer guide ring at a position remote from the cut-out outlet portion of the inner guide ring through which the portion of the film is pulled out from the innermost winding of the film.

Abstract: An upwardly pivotable vent panel assembly as part of an automobile roof structure in which the horizontal pivot connection is defined by a pair of insertion tongues on the forward end of the vent panel engaging matching slots in a vertical wall portion of the roof, the pivot connection being readily disengageable and the lifting linkage being releasable for complete removal of the panel.

Abstract: A multiple-piston press for synthetic-resin coating of large surface-area workpieces is provided with heatable pressure plates mounted horizontally superimposed within a pressure frame to form a gap intended for holding the material to be subjected to pressure. Hydraulic piston-cylinder units are provided for carrying out the pressing process by pressing the plates against each other.

Abstract: An apparatus for separating particles from a gas flow is provided, comprising: is provided on the concave side of each crest, the serrations winningA plurality of corrugated separator plates arranged in spaced parallel relation to each other and defining wave-like flow channels between each other. The warped surfaces of the separator plates are generated in cross-section by at least three circular arcs connected continuously and with alternating directions of curvature. The radius of each of the three circular arcs is different, the radius of the arc representing the crest being the smallest. The arcs define at least one crest between two troughs, forming an intake section and an outlet-section, respectively of each separator plate. A first separating chamber is provided opening towards the gas flow on the convex side of the crest and is formed by a blade projecting from the downstream side of the crest toward its upstream side and running along the crest.

Abstract: An apparatus including combined means to control the size of helicoidal loops of an elongated flexible material and the linear speed of said material carried by horizontal rotary shafts and dipping into a treating agent inside a volume: the material inlet speed controls the speed of one of the shafts; it is positively driven up at the outlet; the effective linear speed inside the volume and the size of the loops are controlled by combined drives using different frictional properties of the material against the shafts and one wall sector of the volume, suitably covered for short temporary stopping contacts.

Abstract: A rotary internal combustion engine which includes a plurality of cylinders equiangularly mounted around a central rotary valve assembly on an axial horizontal shaft, in which more complete combustion and less emission of unburnt gases is achieved. The engine embodies a valving rotor comprising horizontally spaced discs having two properly located intake and exhaust valve passages and related generally cup-shaped intake/exhaust guide means eccentrically mounted on the shaft. This arrangement together with correspondingly horizontally spaced intake/exhaust ports in the respective cylinders, provides for dual intake charges and for the exhaust gas to be discharged twice and more completely in a single exhaust stroke via the properly located exhaust valves. The exhaust valves, which are also in the horizontally spaced rotor discs, are circumferentially displaced from the respective intake valves and also from each other.

Abstract: Device for indicating when a vehicle has travelled a predetermined distance, calling for inspection or servicing of some part of the vehicle. An electrochemical indicator integrates a signal indicative of the vehicle speed to provide an output indication.

Abstract: The invention relates to a feeder rake for the feeding of cut material into the baling chamber of agricultural pick-up and other balers, which is arranged to be driven by a steadily rotating crank and is guided by a swinging rod, which is connected by a link and by a guide arm with two spaced pivot bearings of the tine carrier of the feeder rake, and the guide arm has an overload protection device, upon whose actuation the feeder rake is folded back into a position in which it cannot continue feeding and, when it is freed of its load, it is erected again automatically moving out of the above-mentioned inoperative position into its operating position.

Abstract: The invention relates to an electric clock with an oscillator, especially a quartz oscillator, a frequency divider connected thereto, and a control stage connected to the output of the frequency divider either directly or via a pulse shaper stage. Through the control stage, a stepper motor, preferably a single-phase stepper motor, connected to the hand mechanism is acted upon by square-wave pulses of identical or alternating polarity.

Abstract: A polygonal chassis for a vehicle, having wheels or tracks, particularly intended for travel over rough terrain. The chassis preferably polygonal has peripheral members provided with journals for an inner or an outer train bearing and driving means. The chassis is made of sections joined by articulated flexible couplings in the corners of the perimeter of the frame. A second set of such couplings is provided optionally at the junction of a rigid brace with the frame. A first species of the invention teaches the use of rigid girders as the frame brace, with each girder connected with the outside of the frame by articulate couplings, or the girders are crossing each other and connect to the opposite periphery of the frame by articulate or flexible couplings and in the alternative a rigid bracing of inner longitudinal girders is joined by the same type of couplings to the opposite portions of the frame.

Abstract: An apparatus for continuous measurement of the density of a liquid within prespecified limits, by utilization of the law of refraction,particularly for the continuous measurement of acid density of a storage battery of a motor vehicle for the purpose of determining the state of charge of the battery.The apparatus is equipped with a photoconductive rod, a light source which radiates a pencil of parallel or nearly parallel rays into the rod toward a measuring surface, located at the end of the rod immersed in the liquid. The surface is struck by the pencil of rays at an angle with respect to the surface that equals at most the total reflection angle occurring at the lower limit of liquid density. A photosensitive element is located in the path of the ray pencil opposite a surface deflecting the pencil of rays, which is refracted by the measuring surface into the liquid.

Abstract: In the handling of bundled articles, for example, logs and timber, it has been known to use a large variety of knots and tethering devices with what are known in the logging industry as toggles. Prior known techniques and devices have caused excessive wear on ropes and have been time consuming in forming attachments, particularly in log booms. The present invention provides a one piece toggle having a plurality of rope receiving holes therein and contoured to permit rapid threading of ropes for cables and reducing wear on the ropes or cables to a minimum.
