Patent CA-1307676-C (CA)
Title: Structural element
Inventor: THORSNES OLA O
IPC: E04B5/48
Filed: 1989-02-08
Granted: 1992-09-22
Abstract: A b s t r a c t A building structure comprises two parallel plates (2, 3) attached to means (4) therebetween forming channels (5, 6).  Some of these channels are filled with concrete so that concrete ribs (10, 11) are formed, which preferably are provided with reinforcement (12).  This building structure will in many cases be provided with a cover (9) of concrete. In order to form a connection between the cover and the concrete ribs (10, 11), holes (13) are made in one of the plates (3) in order for a monolithic connection to be formed between the ribs and the concrete.  A shear force reinforcement (15) may be placed into the ribs (10) through the holes (13).  The plates (2, 3) with the channel forming means (4) constitute a prefabricated element (1) which is brought to the building site without holes (13) in said one plate. However, the plate is provided with hole markings (8), but the holes are only made at the building site when it has been determined which of the channels (5) are to be filled with concrete in the particular use at hand.  Since the plate (3) in this manner is not provided with more holes than necessary, the plate (3) retains sufficient strength in order for the element (1) to have sufficient rigidity and strength to withstand traffic loads and the weight of the concrete before it has hardened.

Granted: 1993-04-06
Abstract: ABSTRACT OF THE DISCLOSURE      A hollow fiber membrane fluid processing apparatus comprising a housing, a fluid processing hollow fiber membrane bundle in the housing, partitions fluid tightly securing the opposed ends of the fiber bundle to the housing ends, a space being defined by the hollow fiber membrane outer surface, the housing inner surface, and the partitions, inlet and outlet ports for a first fluid disposed in the housing adjacent the opposed ends thereof in fluid communication with the space, and inlet and outlet ports for a second fluid disposed at the housing ends in fluid communication with the interior of the hollow fiber membranes is characterized in that the portion of the hollow fiber membranes in contact with each partition swells little upon contact with water-containing fluid.  When contacted with physiological saline for priming and the second fluid for processing, the partition-contacting portion of the hollow fiber membranes does not absorb substantial water or expand in wall thickness, that is, maintains the inner diameter unchanged, avoiding any deleterious effect on second fluid flow and an increase of pressure loss.

Abstract: Abstract After quenching, the slag that is generated in garbage and waste incinerators is subjected to an additional washing process in a washer unit (2).  During the wash process, harmful substances such as chlorides and heavy metals, for example, are washed out of the slag.  The subsequent separation of the water from the slag is effected in a separator system (4) and in a drying system (7).  The slag is dried to a maximum water content of 30% and the fine components with a grain size of less than 2 mm are removed from the slag either during or after the drying process.  These fine components and the wash water sludge contain practically all the soluble harmful substances, and must be processed or dumped while observing special precautions.  The remaining clean slag is practically free of soluble harmful substances and can be used as construction material.          Figure 1.

Abstract: DATA CRYPTOGRAPHY OPERATIONS USING CONTROL VECTORS                      Abstract Data cryptography is achieved in an improved manner by associating with the data cryptography key, a control vector which provides the authorization for the uses of the key intended by the originator of the key.  Among the uses specified by the control vector are limitations on encryption, decryption, authentication code generation and verification, translation of the user's data.  Complex combinations of data manipulation functions are possible using the control vectors, in accordance with the invention.  The system administrator can exercise flexibility in changing the implementation of his security policy by selecting appropriate control vectors in accordance with the invention.  Complex scenarios such as encrypted mail box, session protection, file protection, ciphertext translation center, peer-to-peer ciphertext translation, message authentication, message authentication with non-repudiation and many others can be easily implemented by a system designer using the control vectors, in accordance with the invention.

Abstract: A light barrier is restricted to detecting blockage in a limited, constant region before the closing edges of a lift cabin-twin door. Two light emitters or transmitters are displaceably arranged in the door sill and are operatively associated with entrainment elements fastened to the lift cabin doors. The light emitters are synchronously displaced with light receivers mounted at the upper edges of the cabin doors. To increase reliability of operation, the lower edges of the lift cabin doors are provided with cleaning devices which clean the light exit locations of infrared luminescent or light-emitting diodes forming the light emitters during every opening and closing operation. Thus, the cleaning device of one door is arranged to clean the infrared luminescent diode of the light emitter of the other door and vice versa.

Abstract: This device prevents individual components of a load from being thrown off during halting of a conveying vehicle at a high rate of deceleration. A blocking device for the suspension of the caster which instantly assumes a front position as viewed in the direction of travel, prevents the vehicle from forwardly and downwardly dipping about the axle of the center-mounted drive wheels. The blocking device automatically adjusts itself corresponding to the direction of motion. A sliding stop vertically displaceably mounted on a pivotable part of a caster arrangement and a stop component fixedly mounted on the vehicle body cooperate to block the suspension of this front caster when the front caster experiences a predetermined degree of suspension displacement. At the caster instantly assuming the rear position, the stop component and the sliding stop are positioned at 180 DEG  to one another, thus precluding inadvertent engagement and permitting full suspension displacement. When changing direction of travel, both casters pivot automatically about a vertical axis, blocking the suspension of the front caster in the new direction of travel and permitting the rear caster to exploit its full suspension displacement range.
