Title: Locking and unlocking device for a card reader
IPC: G06K13/08
Filed: 1986-09-15
Abstract: A card reader locking and unlocking apparatus has a locking lever. One end of the locking lever supports a hook which hooks over a card when the card is locked in position during reading. A key, when brought into abutment with the locking lever, raises the locking lever so that the hook clears the trailing edge of the card and permits the card to be withdrawn. A solenoid acts on the locking lever by a release lever to electrically lock and unlock the card. The release lever is forked so that movement of the locking lever by the key does not cause corresponding movement of the solenoid armature.

Filed: 1986-03-19
Abstract: Individual elongate elements (wires 2 or strands 4) are 
drawn off stationary coils (21) in such a manner that 
the element (2,4) is elastically twisted. The elements 
(2,4) are guided to a stationary closing means (23) in 
which a bundle of the elements is formed, the elements 
immediately before being formed into the bundle being 
substantially free from any curvature that will result 
in residual slackness in the elongate member (1,3) being 
manufactured. The bundle is withdrawn from the closing 
means (23) and is simultaneously rotated about its axis 
so as to form the elongate member (strand 1 or rope 3) 
and substantially untwist the elongate elements (2,4). 
The product can be at least 300 m long.

Title: Interlace to non-interlace scan converter for rgb format video input signals
IPC: H04N9/64
Filed: 1986-04-24
Abstract: A speed-up memory converts interlaced RGB input signals to double line-rate (progressive scan) form. A vertical detail signal is derived from the RGB input signals before or after speed-up and a vertical peaking signal is derived from the detail signal. During the first read operation of the speed-up memory both signals are added to the speeded-up signals to effect a preshoot of the resultant signal and during the second speed-up memory read operation only the peaking signal added to affect an overshoot of the resultant signals whereby alternate lines of the converted RGB signals exhibit enhanced vertical detail.

Abstract: A device for the release of a diffusible solid in a 
fluid medium which comprises a disc which comprises a 
substantially uniform mixture of said diffusible solid 
and a polymer which is insoluble in and impermeable to 
said fluid medium and impermeable to said diffusible 
solid. The surfaces of said disc are coated with a

fluid medium and impermeable to said diffusible solid, 
with the exception of one or more apertures which extend 
through the disc and expose a portion of the mixture of 
diffusible solid and polymer to the fluid medium when the 
device is immersed therein. The aperture or apertures 
are placed in said disc such that as said fluid medium 
enters the disc through said aperture or apertures, the 
ratio of surface area of diffusible solid exposed to the 
fluid medium to the length of the path through which the 
exposed solid must diffuse to exit the disc remains 
substantially constant.

Abstract: The present invention relates to a surgical drape for use 
in head surgery, comprising a head sheet (1) which is 
intended to be wound around a patient's head in the manner 
of a turban, and a protective sheet (2) which has a grea­
ter length and area than the head sheet (1) and which is 
intended to serve as an underlay for the head sheet (1), 
wherein the head sheet (1) is placed on top of the protective 
sheet (2) in the upper part of the sheet (2) and the surgical 
drape comprised of these sheets (1,2) is folded in a manner such 
that both sheets (1,2) can be placed beneath the head of a 
patient in one working step. According to the invention 
the lower part of the protective sheet (2) has formed therein 
a slit (3) which divides the strip into two symmetrical 
parts and which extends from the bottom edge (22) of the 
protective sheet (2) up to at least the bottom edge (12) of

protective sheet (2) can be used to cover the chest region of 
a patient.  
     The invention provides a surgical drape which is inexpen­
sive in manufacture and easy to manipulate. The surgical 
drape also obviates in many surgical cases the need to use 
additional, conventional surgical drapes.

Abstract: A method of making a rigid angled joint between a 
first length (12) of metal tubing and a second length (18) 
comprises the steps of first applying a rotating 
piercing tool (not shown) under pressure, to the first

Patent EP-0294963-A3 (EP)
IPC: G06K19/077
Filed: 1988-05-23
Abstract: A tag has a memory programmable to store alphanumeric 
indications in a pattern identifying an object associated with 
the tag. The stored indications are convertible to signals 
transmitted to a displaced reader in an individual pattern at 
first and second frequencies to identify the object. The memory 
may be programmed, during the production of a first logic level 
in a signal on a program pin, (a) by the operation of keys on a 
keyboard in a programmer housing, each key representing an 
individual alphanumeric character, or (b) from an external 
source such as a typewriter keyboard used in conjunction with 
the programmer. The signal on the program pin has a second 
logic level to provide for bulk erasing all particular memory 
positions. A configuration signal has a first logic level 
providing for the alphanumeric coding of the memory and a second 
logic level providing for the selection, at particular memory 
positions, of individual capacitors to generate signals at the 
first and second frequencies. When the programming signal has 
the second logic level and the configuration signal has the 
first logic level, bulk information may be erased from the 
memory. Dependent upon the logic levels of the programming and 
configuration signals, (1) information is programmed in the 
memory, (2) the capacitors are selected or (3) programmed 
information is bulk erased when an energizing pin in the 
programmer receives a particular voltage. A detent on the tag 
has a plurality of pads for introducing the different logic 
levels to the programming configuration and energizing pads in 
 
 
the tag. This detent mates with a detent in the programmer 
housing to provide for the introduction of the programming, 
configuration and energizing signals to the tag through the pads 
in the tag detent.
