Title: Processing grain oriented electrical steel
IPC: C25F3/06
Filed: 1988-08-12
Abstract: This invention relates to a method of enhancing linear impressions formed in the surface of grain oriented electrical steel strip, by electrolytically etching said impressions with e.g. citric acid. The impressions may be formed by mechanical wheel scribing or by surface ablation, e.g. by spark discharge or laser treatment, and may be continuous or discontinuous in the form of spots or lines. In accordance with this invention therefore, the initial generation of light impressions in steel strip formed by mechanical wheel scribing or spark ablation techniques can readily be enhanced by application of the electrolytic etching technique to produce a material exhibiting values of power loss (reduced from the original unscribed loss value) which are substantially anneal-proof. In comparison, conventionally scribed material shows no resistance to a high temperature anneal as far as loss reduction is concerned.

found, the known answer to the request having that identical 
record is given to the user to answer his or her request; 
however if no identical record is found in the complementary

IPC: F02M1/08
Filed: 1988-09-02
Abstract: An apparatus for supplying a start-fuel to an internal 
combustion engine for a portable type machine such as a chain 
saw or brush cutter which has an electric battery (41) for use in 
starting. An electrically driven reversible pump (37) is used to

reversed and fuel from the reservoir (32) is directed to a jet (14) at 
the entrance of the carburetor venturi passage (17) to provide a 
rich mixture to assist in starting.

Patent EP-0365018-A3 (EP)
Title: Identity card and its production method
IPC: B42D15/02
Filed: 1989-10-19
Abstract: An identity card, e.g. a cheque card or credit card, usually has a space in which the card user writes his signature when the card is issued. A weak point, as far as manipulations of the cards are concerned, has long been that the signature space could be eliminated and replaced by a counterfeit signature space. According to the invention, in order that such manipulations are easily recognisable and forgeries are consequently made more difficult, the security typography (guilloche print) which anyway covers the area surrounding the signature space is extended on without transition over the signature space also. If the counterfeiting of a signature space provided with such security typography is itself extremely difficult, it is practically impossible to arrange the security typography in such a manner that it passes continuously from the signature space into the area surrounding the signature space. <IMAGE>

engaging with the percussion body, whereby the conversion 
mechanisme can be made simple and small, whilst the frequency 
of the oscillatory motion can be boosted considerably giving 
a better percussion effect on the tool spindle.

Title: Infrared spectral difference imager
IPC: G01J3/28
Filed: 1989-08-04
Abstract: An infrared spectral difference imager capable of detecting and imaging 
an excess or deficit of infrared radiation having a preselected wavelength. The 
imager processes at least two channels of infrared radiation information through 
the sensor stage in order to display an image of the spectral differences present 
in the imager's field of view. The imager principles may be implemented in 
standard forward-looking infrared (FLIR) thermal imagers to obtain pictorial 
representations of the spatial distribution of sources and absorbers of infrared 
radiation within a preselected narrow band of infrared wavelengths. The 
spectral-difference detection capability may be added to scanning systems with 
discrete sensors, to scanning systems with TED or SPRITE sensors, and to 
staring array systems. Implementation techniques include a cost-effective 
manner of providing the time delays required to compare signals from the 
multiple energy channels and an automatic monitor and alarm system responsive 
to the strength of the difference signal.
Patent EP-0364090-A3 (EP)
Title: Method and apparatus for efficient resource allocation
IPC: G06Q10/00
Filed: 1989-08-21
Abstract: A method for optimizing resource allocations in commercial 
enterprises that are characterized by a linear set of constraint relationships of the 
controllable parameters. The method is particularly useful in enterprises where the 
cost function to be minimized is piece-wise linear and convex, or where the cost 
function is linear and the constraint relationships are such that the enterprise can 
conveniently be decomposed into a plurality of relatively independent subentities 
and a correlating portion that expresses the interrelationships among the 
subentities. More specifically, in accordance with the disclosed method, an 
enterprise with a linear system of constraint equations that can be decomposed 
into a master problem and a plurality of subproblems leads to a need to solve a 
system of equations (corresponding to the master problem) where the cost function 
is piece-wise linear and convex. The piece-wise linear problem is solved by a 
method that is a modification of the algorithm invented by Karmarkar. The 
method moves iteratively within the polytope of feasible solutions (as in 
Karmarkar's invention) in a move direction that improves the value of the cost 
function. The move direction is ascertained scaling of the problem and 
determining a descent direction through a sensitivity vector evaluation, and the 
step size is determined through a line search along chosen direction to the best set 
of allocation values along that direction. Whenever possible, that direction 
corresponds to the steepest descent direction. The iterations are repeated until an 
optimal solution is found, whereupon the last evaluated set of allocations 
(controllable parameters of the system) is communicated to the system.

Title: Air dryer for air pressure plants chargeable by a compressor, containing at least one air storing container, especially for air pressure brakes of vehicles
IPC: B01D53/26
Filed: 1990-04-09
Abstract: In the case of such an air drier a connectable regenerating device is assigned to a drying cartridge (3) containing a drying agent (7); by means of this the drying agent located in the drying cartridge (3) is regenerated, that is by means of the compressed air from the compressed air system the damp drying agent is passed through and the bound water extracted from this before it passes out into the open air preferably via a ring filter and an exhaust valve. The regenerating device has a timed switch which can be switched on by the control pressure of a pressure regulator preferably incorporated on the device in order to initiate regeneration at pre-determined time intervals. The switch (45) contains a piston (43) to which compressed air can be admitted when the control pressure of the pressure regulator is reached, which piston, as a function of a link motion in predetermined stages and by means of a valve plunger (59) opens a connection which allows the compressed air to flow back out of the compressed air system through the drying agent (7) in the drying cartridge (3). The piston (43) acts in concert with a connecting member rotatable according to the piston movement, which member in a predetermined angular position carries the valve plunger (59) with it, thereby opening the connection for initiation of the regeneration. <IMAGE>

Title: Serial testing technique for embedded memories
IPC: G01R31/28
Filed: 1990-02-07
Abstract: A testing circuit interfaces serially with the data path 
of an embedded memory circuit formed from at least one memory unit 
having separated data input and output lines and tandem 
addressing. Part of the testing circuit is a series of two-input 
multiplexer units which are adapted to be embedded on the same 
chip as the memory circuit. The outputs of the multiplexer units 
connect to a respective one of the data input lines of the memory 
circuit. Excepting the first bit position, a first input of each 
multiplexer unit is adapted to connect to the data output line of 
the adjacent bit position in the memory circuit. The second 
inputs of the multiplexer units are adapted to connect to the data 
bus of the chip. A further part of the testing circuit is a 
finite state machine which is adapted to connect to the first 
input of the multiplexer unit at the first bit position and to the 
data output line at the last bit position. During testing, the 
finite state machine actuates the multiplexer units to connect the 
first inputs, and for each address outputs a series of test bits, 
shifts those bits through the addressed word by a series of read 
and write operations, and examines those bits after their passage 
through the addressed word for defects in the memory circuit at 
that address. The finite state machine may or may not be embedded 
on the same chip as the memory circuit.
