Abstract: The invention concerns a gas filter unit or cartridge type, including a filter material put together to form one or several filter bags, and a support frame of essentially U-shaped cross-sectional configuration, including a web portion and two lateral leg members in adjoining relationship, the filter material closest to the mouths of the filter bags being clamped in position between said lateral leg members. In accordance with the invention, the frame includes profile sections of a flexible material, preferably a plastics material, at least one of said lateral leg members being hingedly interconnected with the web portion, in addition to which locking means are provided to retain the corresponding lateral leg member in its clamping position in which it is pivoted into engagement with the other lateral leg member.

Abstract: A red brick comprising waste foundry sand of 30.about.50 wt %, dusts of 5.about.10 wt %, and a remainder of clay. The waste foundry sand and dusts can be efficiently recycled, and the quantity of the sand used, the supply of which sand which is nearly exhausted, can be reduced. The heating temperature in the red brick manufacturing process is remarkably lowered, and the economical efficiency of the manufacturing process is improved greatly by using iron oxide included in dusts, instead of a chemical compound to obtain desired color.

Abstract: An air filter apparatus for engine intake-air in which a filter support member is stretched in a filter attaching frame of an outer frame structure member, and filter is supported on the filter support member, wherein the filter is integrally incorporated with the filter support member.

Abstract: An arrangement for a sailing boat which exhibits a jib furling system (2) comprising a sail furling part (5) extending between the hull and mast of the boat, which sail furling part is rotatably driven by means of a manually actuated operating line (6) which drives a drive part (7) that is connected to the aforementioned sail furling part (5) to achieve furling of the foresail around the aforementioned rotatable sail furling part (5), and so that unfurling of the sail from the aforementioned sail furling part (5) is possible. A gear (9) is arranged between the aforementioned drive part (7) and the rotatable sail furling part (5). The gear (9) is provided with devices to enable gearing to be obtained between the aforementioned drive part (7) and the rotatable sail furling part (5).

Abstract: Pallet level loading apparatus with a three-sided opened top enclosure and a bottom in which a cantilever-supported lifting platform is vertically movable. The lifting platform is driven by a hydraulic system housed in the rear wall of the enclosure. The platform may be locked in position at a predetermined height within the three-sided enclosure to permit its movement from place to place by a hand pallet or forklift. The apparatus further includes a torsion shaft. The torsion shaft arrangement distributes eccentric loads on the cantilever supported lifting platform so that the platform will not experience lateral tilt. Two vertical guide masts are arranged for receiving a roller arrangement of the lifting platform in order to prevent front and back platform tilt.

Abstract: There is provided a burette apparatus having a delivery tube connecting a fluid bag to a burette assembly, via a fluid entry spigot formed in an end cap assembly of the burette assembly, the end cap assembly having a bypass spigot connected to the delivery tube and usually closed by clip, to allow an override for adding liquid to the burette. The end cap assembly closes the upper end of the transparent, cylindrical burette body, into which extends a stainless steel tube extension of the fluid entry spigot, the lower end of the burette body being closed by a lower closure assembly having a check valve and a drip chamber. An outlet tube passes from the drip chamber to the patient via regulating clamp. A float assembly is located in the burette body including an extension rod provided with a resilient cup adapted to engage the open end of the stainless steel tube extension.

Abstract: A packing element for mass transfer column or towers and/or heat transfer columns or towers through which a gas and/or a liquid flows, is provided herein. The packing element possesses a plurality of exchange surfaces. The exchange surfaces of the packing element are formed by the surfaces of half-wave-shaped strips or wave-shaped strips. The packing element also possesses at least one first group of strips containing at least one half-wave-shaped strip or wave-shaped strip having a first periodic length, and at least one second group of strips adjoining thereto and containing at least one half-wave-shaped or wave-shaped strip having a second periodic length. Preferably, at least one outer side of the packing element is formed as a boundary element joining at least some of the strips of a group of strips.

Abstract: A novel pourable packing element is provided herein for use, in particular, in mass transfer and/or heat transfer towers through which a gas or a liquid flows. The exchange areas of such packing element are formed by the surfaces of half-wave-shaped or wave-shaped strips. The packing element possesses at least a first group of strips having a first periodic length and at least one adjoining second group of strips having at least one strip with a second periodic length. The first periodic length of a selected first strip in the first group of strips, (such selected first strip adjoining the second group of strips), and the second periodic length of a selected second strip in the second group (such selected second strip adjoining the first group of strips), is matched to each other in such a way that two adjoining strips of the first group of strips and the second group of strips are in contact with one another at at least one point, so that liquid can pass from one strip to the other strip.

Abstract: In a power tilt device, an opening/closing valve is arranged in a free piston, and an operating member is arranged within a piston rod of a piston and piston rod assembly contained within a closed cylinder. The operating member contacts a supply of hydraulic fluid from an opposite piston side space of a free piston to a first chamber above the piston by opening the opening/closing valve when coming into contact with an end wall of the cylinder during an upward tilting phase of the boat motor. Upon contact, the piston rod is extended outside of the cylinder causing a discharge of hydraulic fluid from the first chamber to an external reservoir, during which time the piston side space and the opposite side space of the free piston are fluidly interconnected.

Abstract: The present invention relates to a revolving sunning bed, comprising a fixed support base, a revolving platform and means of mutual constraint which allow the platform to revolve with respect to the support base. To make it more comfortable to impart motion to the platform, the bed further comprises a motor-driven device and a related command and control device, accessible even while lying down.

Abstract: A tilt cylinder apparatus for a boat propeller unit comprising a cylinder unit containing an inside cylinder and an outside cylinder, an opening portion of the cylinders being closed by rod guides, a piston which is connected to an end of a piston rod placed through the rod guides and disposed slidably in the inside cylinder, a reservoir chamber which is formed between the inside cylinder and the outside cylinder and contains a fluid chamber and an air chamber, a communicating path which is formed in the rod guides and ensures a communication between the rod side chamber and the reservoir chamber through a conduit pipe disposed in the reservoir chamber, and a selecting valve which is disposed in the rod guides and selects an opening or closing of the communicating path following an outside operation, wherein when the communicating path is opened, air pressure in the air chamber of the reservoir chamber pushes the piston rod out of the cylinder unit so as to tilt up the boat propeller unit.
