Abstract: Pin point foundations are formed, the ground is flattened and levelled at the level of these foundations, peripheral recoverable shuttering is disposed on the ground and continuous rows of non recoverable shuttering defining the ribs are disposed at the center. The rows of shuttering are spaced apart by baryte cardboard elements providing sealing and insulation. On the upper face of the non recoverable shuttering are disposed means for spacing the trellis work reinforcing the floor. Then the concrete is poured by pumping and, after drying out the floor, only the peripheral shuttering is recovered.

Abstract: A multi-conic shell and a process of creating multi-conic shells from flat materials which are bent and thereby forced into the configuration of continuous regions from oppositely oriented, tangential cones to create variably configured building structures and variably configured lightweight structural panels. The process of creating multi-conic shells from connecting cone segments corresponding to a theoretical array of regular (opening downward) and inverted (opening upward) cones provides an unlimited number of variations for the design of building structures and the design of structural panels. Such multi-conic structures achieve excellent strength to weight ratios by distributing loads into tension and corresponding tetrahedron structures which propogate throughout the shell.

Abstract: A method and related apparatus for forming a sluiceway adjacent a wall and cement floor includes a sluiceway form made from a generally rectangular sheet of biodegradable material having a number of generally parallel fold lines to define a plurality of contiguous sluiceway panels disposed inwardly of opposite marginal portions of the sheet which are folded into face-to-face relation with each other to form an elongated sluiceway form having a body portion defined by the sluiceway panels and a tab defined by the marginal portions projecting from the body portion and extending along the entire length of the body portion. The sluiceway is formed by positioning the sluiceway form adjacent the wall with at least a part of the body portion below the level of the grade and the free edge of the tab extending in a generally parallel relation to the grade level. The tab is secured to the wall and the concrete floor is poured with the sluiceway form in position.

One or more data carousels is rotatively mounted on the newel, each carousel comprising a plurality of radial arms in vertically adjustable offset stacked array. Each arm has a slidable upwardly extending bracket on each side which cooperate to hold data-containing materials therebetween.

Abstract: The use of a bifurcated joint to attach a conveniently sized metal flange to a flexible bellows material has been widely used, for example, in the manufacture of a building construction expansion joint cover. The known bifurcated joint is formed by clamping and engaging a marginal edge of the bellows material between opposed folded portions of the metal flashing. It has been found that the attaching force provided by this joint can be enhanced by providing teeth or protrusions in a portion of the metal bifurcated joint. Preferably a punch is used to upset teeth from one surface of the joint, preferably a corrugated portion of the joint, and then bend the thus toothed and corrugated portion into clamping engagement with the marginal edge of the bellows. The toothed hole clampingly engages the bellows material without piercing it and prevents pull out, both prior to curing of the adhesive bond as well as thereafter.

Abstract: An insulated glass skylight assembly is provided that is adapted to be mounted to cover an opening in a roof structure.

A swinging window unit is provided which includes an insulated glass insert, an inner supporting frame, and an outer encasing frame. The insulated glass insert is of a predetermined size and shape to substantially conform to the opening in the roof structure, and the inner supporting frame is adapted to engage and seat on the liner and to support the glass insert. The outer supporting frame is adapted to be coupled to the inner supporting frame and capture the glass insert therebetween.

Abstract: A security screen having two rams to operate the screen which are located against the panel of the screen, the rams being connected at one of their ends substantially symmetrically relating to the center of the screen at or adjacent the top thereof and, at their other ends, substantially symmetrically relative to the screen to a structure beneath or beside the screen, the connections being such as to permit at least a degree of rotation of the rams relative to the panel and the structure, the arrangement being such that, as the rams are extended, the outward component of forces of the rams are substantially equal and opposite, the resultant being an upward component which can drive the screen upwardly rapidly.

Abstract: A portable collapsible porch is provided for use with campers, camping trailers and the like which includes a foldable platform structure and collapsible legs, stairway and protective rail structure, thereby requiring minimal space for storage and transportation, and further includes adjustable legs to facilitate use in uneven terrain.

Abstract: This invention relates to adjustable seats and components therefor including mechanisms for assisting in their adjustability and a hand-operated lever employed for both adjusting the inclination and height of the seat cushion above the base of the seat and positioning and moving the seat longitudinally.

Abstract: An exercise rowing machine is disclosed which includes a stationary seat and a rocker assembly. A handle grip coupled to a sprocket assembly drives a flywheel mounted with the rockers assembly. Fins attached to the flywheel provide braking.

Abstract: An adjustable seat assembly for exercising apparatus which may embody a hand-held weight frame, a movable weight supporting frame, a leg exercise unit or other exercise device. The seat assembly has an elongate seat mounted on a base for endwise adjustment relative to the base to accommodate the seat to various exercise devices. The seat has a seat portion, a back portion, and means including an arcuate support extending between the back portion and base and movable endwise relative to the base of pivotally adjusting the back portion relative to the seat portion to a range of angular positions between an upright position and a downwardly inclined position.

Abstract: An open web structural support member such as a truss is described whose length may be adjusted in predetermined increments and which employs an incremental adjustment means for adjusting the effective length of the end web in order to compensate for adjustment in the length of the truss to maintain a rigid and stable truss. An apertured chord plate is attached to the upper chord member by a pin placed in a selected one of the adjustment holes in such chord plate for adjusting the length of the truss. The chord plate is connected to a mounting bracket at the end of the upper chord member. The incremental adjustment means for the web includes an adjustable link means connected to an end web member to form an end web assembly of adjustable length attached between the mounting bracket and the lower chord member.

Abstract: Thermally insulating panels are formed at opposite sides with finishing edge strips about which sheet metal facings of the panels engage, the strips having ribs and grooves to allow mortise and tenon interconnection of the panels. A fold between a groove and a rib of the respective panel receives a metal insert which provides structural support and interengaging flanges of the insert, which preferably is composed of high density PVC, can interlock for effective sealing.
