Abstract: Device for actuating and controlling the movable bottom of a refuse collection or like body, notably in a refuse collection vehicle and for improving the performance of the main functions of such body or vehicle, by providing a uniform compression of the refuse within the body and ensuring a more reliable operation under recompression and ejection conditions, while eliminating the risk of wrong manoeuvres. This device comprises a telescopic-type hydraulic cylinder and piston actuator controlling the movements of said movable bottom, namely the compression of refuse and the development of a retaining force during the ramming of the refuse by the ramming means incorporated in the hinged door at the opposite end of the body. To this end, an automatic valve is interposed in the hydraulic circuit controlling said movable bottom, said valve remaining close as long as the pressure exerted by the refuse ramming means or the pressure exerted by the refuse against said bottom remains below a predetermined value.

Abstract: A method for the manufacture of reinforcement members, in which steel rods are first bent into a U shape and the two arms of the U-shaped piece are then bent off at right angle, at a particular distance from the cross bar of the U. These steel rods are placed at preselected intervals of the U-shaped portion and with their bent-off arms lowermost, into a trough-shaped basin with outward sloping side walls. A liquid foam material is then brought into the basin so that the preshaped reinforcing rods will be immersed with their bent-off arms in the solidified foam material, while the brackets project with their cross bar from the foam material.

Abstract: Connection valve for the temporary connection of equipment to conduit systems for pressure fluids, which valve has at least one terminal valve attachable to the conduit systems and including a normally closed spring pressed check valve, a control valve, quick coupling means detachably connecting said terminal valve to said control valve and said control valve having an adjustable prismatic pin having a space therearound and engageable with said check valve for opening the same as desired providing communication for fluids between said terminal valve and said space around said pin in said control valve and said control valve having a side outlet communicating with said space around said pin for receiving fluid therefrom.
Abstract: An identification card holder in the form of a transparent plastic envelope open only at one end whereby an identification card can be inserted in and viewed through the holder and a safety pin having the pointed end portion extending through openings in the rear of said envelope for attachment to clothing of a user thereof and a method of forming said holders.
Abstract: The invention provides an improved means for connecting the components of demountable furniture, commonly referred to as `knock-down` furniture, and provides a connector which comprises two elements each securable by screws to a component of an article of furniture and connectable to each other by a bolt, characterized in that one element has a flange which in use conceals the fastening screws of the other element, said other element conceals the fastening screws of the said one element, and the bolt connecting said elements is concealed by a push fit closure insertable in a countersink of the bore of said second element through which the bolt passes. In a preferred form said elements also are provided with interfitting parts which accurately align said elements in connectable position.
Abstract: The release control lever 14 is mounted on a shaft 15 passing through the casing 1 of the apparatus and which is rigid with a crank-shaft 19. The crank-shaft 19 is connected through a rod 20 to the middle portion 21 of a rocking lever 17 pivoted at one end to the control links of clamp 5 and at the other end to a rod 18 pivoted in turn to one end of another rocking lever 16 having its other end pivoted to the control links of clamp 4 while its middle portion 22 is connected to a fixed pin 23. The rotation of the release control lever 14 results in a translation of rocking lever 17 and a rotation of rocking lever 16.
Abstract: This invention provides a non-expendable support or carrier for a disposable bedpan and broadly comprises a center portion shaped to receive the receptacle portion of a bedpan, a web adapted to fit below and support the conventional seat part of the bedpan, and extending from said web a downwardly and outwardly extending flange which for the major part of its circumference is only about half the depth of the dished part. At opposite sides and rearwardly of the support's transverse center line said flange is formed with wing portions which extend downwardly and outwardly to or almost to the base of the dished part. The extremities of said wing portions preferably are widened or flanged to provide broad smooth bearing surfaces.
Abstract: A centrifugal type oil cleaner having a housing with rotor therein and passageways for feeding the oil into the bottom of the rotor and past narrow spaces for separating the oil and contaminations with the clean oil going out openings in the rotor rotating said rotor and them passing to a bottom outlet in said housing for reuse.
Abstract: A connecting fitting for pressure conduits including a pair of coupling elements with corresponding bores and one element having a female portion capable of receiving a male portion of the other element and said female portion having spaced apart recesses with seals positioned therein cooperating with exterior surfaces of said male portion to provide seals therebetween. One of said seals spacing said male and female parts in the assembled position thereof and having a recess providing a pair of lips with an orifices therebetween opening into said space between said parts for receiving a medium under pressure in said conduits, for spreading said lip into sealing engagement with said male and female parts.
Abstract: A boat auxiliary motor support, comprising a base, a bracket and two levers between which is mounted a control system comprising one cylinder, one piston and one hollow piston rod containing a control rod free to slide axially. The interior of the cylinder is divided up by a floating piston into a chamber filled with gas and forming a gas sprint and two chambers filled with oil and separated by the piston. The control rod rests against a valve mounted in the piston, that allows the oil to flow from one chamber to the other through a duct. A control system is mounted at the free end of the control rod to open the valve.
