Abstract: PCT No. PCT/DK91/00092 Sec. 371 Date Sep. 4, 1992 Sec. 102(e) Date Sep. 4, 1992 PCT Filed Mar. 25, 1991 PCT Pub. No. WO91/14842 PCT Pub. Date Oct. 3, 1991.For the fastening of a protecting or shielding cover, in particular a tarpaulin, to a scaffolding, a fastening member is provided which has an anchor pin to be arranged on the external surface of the tarpaulin, a flexible strap being firmly connected with the anchor pin and having a slit or opening through which the free end of the strap may be pushed and a toothing to prevent the strap from being retracted. The slit or opening is provided in a clamping member at the opposite end of the strap in relation to the insertion end and the anchor pin is connected with the strap at a distance from the clamping member conforming to the dimensions of a frame member of the scaffolding, while the distance of the anchor pin from the insertion end is substantially larger. For mounting the fastening member use is made of a tool in which a hollow piston axially displaceable in a holder has a pointed cutting end and is designed to receive the anchor pin of the pin being pressed out of the hollow piston by use of a slide accommodated in the piston.

Patent CA-1276213-C (CA)
Inventor: GILBREATH WILLIAM E
IPC: E04G7/30
Filed: 1985-10-01
Granted: 1990-11-13
Abstract: SCAFFOLDING WITH CONNECTION AND RETENTION DEVICE AND     ASSEMBLY METHOD THEREFORE            ABSTRACT          Improved apparatus is provided for temporarily securing together scaffolding members.  A slotted stud fixed to a scaffolding support member is provided with a pivotal dog rotatable within the slot for receiving the hole punched end of a cross member.  A spring and washer having a transverse bar member within the slot are permanently retained on the stud to prevent misuse of the device.  Rotation of the dog to receive the cross member causes axial movement of the washer and compression of the spring.  Further compression of the spring by the cross member allows the dog to return to its lock position by gravity.  The spring, washer, and dog thus cooperate to either expel the cross member from the device or lock the cross member in place, which substantially increases scaffolding safety.

Title: Cross blending electro-dynamic/friction brake system for multi-car trainconsist having mixed power and non-power cars
Inventor: RUMSEY STEVEN C
IPC: B60T13/66
Filed: 1986-11-04
Granted: 1991-04-16
Abstract: (Case No. 8299) ABSTRACT OF THE DISCLOSURE    A cross blending brake system for a multi-car train having power cars that provide regenerative braking through the electro-dynamic action of the car's traction motors, as well as friction braking through an electric/friction brake blending valve, and non-power cars that provide friction braking only through an electric/friction brake blending valve.  Since the regenerative brake effort on the power cars is limited only by the available wheel to rail adhesion on these cars, the regenerative action of the electro-dynamic brake provides brake effort in excess of the power car brake requirement, thus reducing the friction brake requirement of the non-power cars, which is limited by the lower threshold energy absorption ability of the wheels.  The cross blending control utilizes the excess power car regenerative braking to avoid overheated wheels, while at the same time realizing a net energy savings and reduced brake shoe wear, particularly at maximum levels of regeneration.

Abstract: ABSTRACT OF THE DISCLOSURE        A broadband signal cross point switching equipment comprises a cross point matrix having FET switch elements formed with a switching transistor and a holding circuit for providing a through-connect or inhibit signal.  The matrix has input lines and output lines and the switching transistor includes a main electrode connected to the respective output line.

Title: Second harmonic generation with n,n'-substituted barbituric acids
Inventor: HARELSTAD ROBERTA E
IPC: C07D239/62
Filed: 1987-09-18
Granted: 1990-12-27
Abstract: Abstract This invention is concerned with materials for nonlinear optical devices for the conversion of optical energy at one frequency to optical energy at another frequency.          Laser techniques have been developed so that it is possible to obtain a limited number of fundamental frequencies of coherent laser light by utilizing solid, gas, and liquid media.  However, in many applications, laser light having frequencies not among the fundamental frequencies obtainable is required, and in some cases laser light exhibiting a continuous spectrum over a certain range of frequencies is required.          Inorganic materials have been used extensively for nonlinear optical applications.  However, they are only of limited use because of their bandwidth limitations.          The possibility of using organic materials in nonlinear optical devices has generated much interest recently because a large number of organic materials are available for investigation and because they do not have the bandwidth limitations of inorganic materials.          This invention provides devices comprising a laser source of coherent light radiation at a fixed fundamental frequency, a crystalline N,N'-substituted barbituric acid that crystallizes in a non-centrosymmetric configuration, means for directing the output radiation of the laser onto the N,N'-substituted barbituric acid, and output means for utilizing the second harmonic frequency.

Granted: 1994-03-22
Abstract: TITLE:  AERATION APPARATUS AND METHOD     ABSTRACT OF THE INVENTION     Improved methods and apparatus are provided for intro-ducing and entraining air into a waste liquid, thereby increas-ing the quantity of dissolved oxygen in the liquid to enhance the aerobic treatment process.  A power driven propeller is pre-ferably positioned at the discharge end of conical-shaped transition housing, and draws in air while waste water is con-trollably introduced to the transition housing from below the surface of the water.  The housing upstream from the propeller is primarily an air chamber with incoming streams of water, while the housing downstream from the propeller is filled with waste water having minute entrained air bubbles.  The water and entrained air are thus discharged downwardly, and the axis of the equipment preferably inclined to increase circulation in the waste water pond or tank.  The techniques of the present invention have relatively low power requirements while substan-tially increasing gas concentration in the liquid.

Granted: 1993-03-16
Abstract: ISOMERIZATION PROCESS AND APPARATUS     ABSTRACT OF THE DISCLOSURE    Processing  and  apparatus  are  provided  for upgrading the octane of a mixed hydrocarbon gasoline feedstock by an integrated adsorption-isomerization process   which   catalytically  isomerizes  normal paraffinic hydrocarbons and concentrates non-normals in a product stream, in both the reactor-lead and adsorber-lead configuration.     The process includes passing an adsorber feed stream comprising hydrogen as well as hydrocarbons to an adsorbent bed to adsorb normal hydrocarbons. The  hydrogen  is  preferably  obtained  from  a  hot hydrogen-containing  process  stream  which  is not cooled or separated into component parts prior to forming the adsorber feed.  In some embodiments, the hot-hydrogen containing stream comes from reactor effluent and in others from desorption effluent.     According to the invention, the only hydrogen which will  require  cooling and separation from a hydrocarbon component is that which is recycled for desorption.  The invention provides improved energy efficiency  and  can  reduce  equipment  size  and complexity.
