Patent EP-0282125-A3 (EP)
Title: Snow removing and dissolving apparatus
IPC: E01H5/10
Filed: 1988-02-29
Abstract: Snow removing and dissolving apparatus carried 
by a self-propelled motor vehicle (10) formed by 
at least one rotary drum (12) arranged in front of 
the vehicle. A screw conveyor (14) picks up the 
snow collected by the rotary drum and conveys it 
to a heating chamber (42) to obtain an initial 
liquefaction. The remaining moving snow accumu­
lates in a bin (16) which by a solution (78) having 
a low freezing point completes the dissolution.  
     The apparatus is particularly useful for use 
in highly urbanized areas.

Title: Effluent treatment
IPC: C02F1/76
Filed: 1988-01-04
Abstract: A catalyst for decomposing an oxidising agent, such as hypochlorite ions, in an effluent comprises an intimate mixture of at least one finely divided Group IIA oxide and finely divided nickel oxide, and/or hydrates thereof, supported on pieces of a non-porous substantially inert material. Some of the nickel may be replace by cobalt. The Group IIA oxide forms 0.5 to 50% by weight of said intimate mixture. The nickel and Group IIA oxides may be applied by contacting the support with a solution of a suitable salts, eg nitrates. Where the support is a Group IIA compound, eg magnesia, the Group IIA oxide may be incorporated into the intimate mixture by contacting the support with an acid solution of the nickel salt. In use the nickel oxide is oxidised to a higher oxidation state than NiO.

Title: Supercharging device of an engine
IPC: F02B39/16
Filed: 1989-03-31
Abstract: In the present invention, in addition to a main 
throttle valve (4) which is conventional, a sub-throttle valve (5) 
for exclusive use of a supercharger is provided. By this sub-­
throttle valve (5), a flow rate of intake air is throttled by 
the fixed amount when the mechanical supercharger (6) is 
switched from a non-connected state over to a connected 
state. This makes it possible to prevent supercharged air 
from being bypassed to the upper stream of the supercharger 
through the bypass (21) and also prevent generation of air intake 
noises. Moreover, in the case where the mechanical 
supercharger (6) is of a type involving the interior 
compression, at the time of switching operation of the 
switching means, torque shock can be prevented and 
controllability on engine output by the accelerator pedal is 
improved.

Title: Portable apparatus with variable rating battery charger for recharging interchangeable battery packs
IPC: H04B7/26
Filed: 1989-05-05
Abstract: In a portable radio telephone apparatus, a desired one of interchangeable 
battery packs (2) is mounted. Each battery pack (2) contains a rechargeable 
battery (24) of a particular ampere-hour rating and a switch (23) for 
identifying the ampere-hour rating of the battery being used. In one em­
bodiment, multiple charging circuits (31, 32) are selectively connected to the 
battery in accordance with the identification given by the switch for 
charging it with a current that is optimum for the battery's ampere-hour 
rating. In another embodiment, the charging circuit includes a switching 
regulator circuit for generating a charging voltage that can be varied in 
accordance with a control signal applied thereto. The control signal is 
derived by detecting a difference between the charging voltage and a 
reference voltage. The switching regulator controls the charging voltage 
so that the voltage difference reduces to zero.

Filed: 1989-08-18
Abstract: A patterned microwave interactive element and 
laminate including a patterned microwave interactive 
element for use in forming food packaging materials 
that may be employed to store and subsequently cook the 
food stored therein are provided. The pattern of the 
microwave interactive element is selected to focus the 
heat generated to predetermined areas of the food 
contained in the packaging. Areas where the microwave 
interactive element has been deactivated may be formed 
by a variety of methods, such as by demetallization, by 
the application of an inactivating chemical, by 
mechanical means and the like, to create a preselected 
pattern of inactive areas relative to the active areas, 
thereby controlling the temperatures produced in 
different sections of the packaging material. Optimum 
browning and/or crisping of the microwave heated food 
product may be achieved by selecting a pattern of 
microwave interactive and inactive areas tailored to 
specific food products.

and a control shaft (21), which is substantially parallel to 
the sleeve. The control shaft (21) is fixed in an axial 
direction and is rotated about its own axis by a positioning 
motor (30) controlled by a control and adjustment unit (40).

bration by adding the aromatic organic-substituted siloxane 
to a preformed mixture of acid-catalyzed poly(aliphatic 
organicsiloxane).

Abstract: An improved passive infrared balanced detector is 
disclosed that reduces false alarm rates induced from random 
thermal activity and other causes of splitting of the field(s) of 
view of the balanced detector into distinct and independent 
regions. The detector includes balanced elements selectively

Patent EP-0463225-A3 (EP)
Title: Method and apparatus for improved melt flow during continuous strip casting
IPC: B22D11/06
Filed: 1990-10-04
Abstract: The continuous casting of metal strip (21) using the melt overflow process is improved by controlling the weir conditions in the nozzle (19) to provide a more uniform flow of molten metal (12) across the width of the nozzle (19) and reducing the tendency for freezing of metal along the interface with refractory surfaces. A weir design having a sloped rear wall (28) and tapered sidewalls (29) and critical gap controls beneath the weir (26) has resulted in the drastic reduction in edge tearing and a significant improvement in strip (21) uniformity. The floor (34) of the container vessel (18) is preferably sloped and the gap between the nozzle (19) and the rotating substrate (20) is critically controlled. The resulting flow patterns observed with the improved casting process have reduced thermal gradients in the bath, contained surface slag and eliminated undesirable solidification near the discharge area by increasing the flowrates at those points. <IMAGE>
