Patent EP-0199544-A3 (EP)
IPC: B66F9/14
Filed: 1986-04-17
Abstract: A fork lift truck which has a mast 13 and a sub-frame 22 
which moves up and down the mast is provided with a 
carriage 30 which is mounted for sideways movement 
relative to the sub-frame.  
     The sideways movement is achieved by rams 40, 41 
connected between the sub-frame 22 and the carriage 30 and 
located to either side of a central region to provide better 
visibility.  
     The fork mounting is an integral unit to reduce the loss 
of lifting capacity resulting from add-on side shift arrange­
ments.

Filed: 1986-04-17
Abstract: The invention relates to an apparatus which enhances the sense of touch when placed between the fingertips of the user and the object being touched and which comprises a liquid lubricant inside a sealed enclosure.

Title: Collapsible box
IPC: B65D5/32
Filed: 1986-08-29
Abstract: A pre-form for a box may be transported flat and then opened out to form a complete box without the need for stapling, glueing, etc. The pre-form defines four side faces 11 and 13 of the box and four flaps 18 and 24 which flaps are folded towards each other on opening out of the box to form the box bottom, which flaps also impart stability to the box. Each first flap 18 is of reduced width remote from its adjacent side face and has a slat 19 extending thereacross to form projecting tabs 19a. On folding the flaps together, the tabs 19a pass through openings in the second flaps 24 subsequently to resist bursting of the box bottom and the ends of the tabs 19a engage strip 29 of side face 11 to resist lozenging of the opened out box.

Patent EP-0231895-A3 (EP)
IPC: H01L29/74
Filed: 1987-01-30
Abstract: The present invention relates to a buried gate type gate 
turn-off thyristor. A low-resistance layer which is buried in a 
cathode base layer has a multiplicity of small bores below a 
cathode emitter layer. The distance between each pair of 
adjacent small bores and the thickness of the low-resistance 
layer are each set so as to be smaller than the carrier diffusion 
length in an anode base layer. In an on-state, carries flow 
through the low-resistance layer, thereby allowing the low-­
resistance layer to become conductive, and thus lowering the 
on-state voltage. A reduction in the dimension of the small 
bores lowers the resistance of the low-resistance layer and 
hence lowers the gate drawing out resistance, so that the 
interrupting capacity is improved. When gate turn-off thyris­
tor is arranged so as to have an amplifying gate structure, the 
distance between each pair of adjacent small bores in the 
amplifying auxiliary thyristor section is set so as to be greater 
than the carrier diffusion length in the anode base layer. In 
consequence, the on-state voltage in the auxiliary thyristor 
section is increased, so that the current selectively flows 
through the main thyristor section, and the auxiliary thyristor 
section automatically turns off. Accordingly, when the thyris­
tor is to be turned off, it suffices to turn off the main thyristor 
section alone.

Abstract: According to the present invention, in the first instance, new aminopolyols, which can be obtained from the disaccharides isomaltose, isomaltulose and  alpha -D-glucopyranosyl (1->1)-D-fructose, are prepared. These compounds, designated as isomaltamines and having the formulae:    <IMAGE>  (I)   <IMAGE> (II) <IMAGE> (III)  as well as mixtures of the same, are produced by the reductive amination of the aforementioned saccharides by means of ammonia or hydrazine compounds in the presence of catalysts, such as Raney nickel, and hydrogen, or by means of complex metallic hydrides, such as sodium borohydride, in solution or suspension. The invention relates, furthermore, to the N-acyl derivatives of the individual isomaltamines or their mixtures as well as to the production of the N-acylates by a selective N-acylation. Depending upon the nature of the acyl radical, these acylates can be used for example, as surfactants or (similarly to N-acrylamide) for the production of polymers.

Abstract: An improved crane (10) is disclosed which can be 
reconfigured from a lifting configuration to a stowed 
configuration. In the stowed configuration, the over­
all height of the crane (10) is much reduced to permit 
the crane to be moved under overhead obstructions and 
also lower the center of gravity of the crane to 
increase stability. A backleg (30) of the crane pro­
vides a novel tension bearing capability where tubes of 
varying diameter are telescoped within each other. The 
backleg can be telescoped to a minimum length limited 
by contact between interior reinforcing rings (118) and 
stop blocks (122) and telescoped to a maximum length, 
limited by contacts between annular stop rings (124, 
126) mounted on the telescoped tubes.

Abstract: Television receiver 1 of Figure 1 has a liquid crystal display 2 formed of a lattice of display elements 3 made from liquid crystal material, each element being individually acutable, the lattice of elements 3 being backlit by fluorescent tubes 4 whose light intensity and duration of operation can be controlled. The video signal has a 70Hz scan rate and a scan period of 14mS, each picture of display information having an 8-bit word for each display element, a word beginning with the most-significant-bit and ending with the least-significant-bit.

Once all the elements are set, driver control unit 7 activates the tubes 4 for a time duration and intensity appropriate to the significance of the bit.

Patent EP-0338129-A3 (EP)
Title: Transceiver coupler for one-pair cabling of a high-speed network
IPC: H04B1/58
Filed: 1988-12-09
Abstract: A coupler (10) suitable for connection of a transceiver 
to a local-area network (LAN) the nodes of which 
are interconnected by single unshielded twisted-­
pair wires (12). The coupler is constructed of 
inexpensive components yet supports communication 
rates of ten million bits per second. The coupler 
avoids "collisions" which would otherwise occur 
when using single 2-wire pairs. A transmit-sensing 
portion (52) of the coupler detects operation of 
the transmitter portion of the transceiver and 
forces a pair of transistors (32,34) to a state 
in which one transistor is conducting and the other 
is non-conducting. A resistor (22) connected to 
the non-conducting transistor develops a signal 
across its terminals approximately equal to zero 
voltage. The signal across the resistor is applied 
to the inverting and non-inverting inputs of an 
operational amplifier (62) which generates a signal 
conducted to the receiver portion of the transceiver. 
In this way, during transmission the coupler assures 
that no signal will be received by the transceiver. 
The transmit-sensing portion (52) will also detect 
disablement of the transmitter portion, and will 
cause the formerly non-conducting transistor to 
become saturated; in turn causing the signal across 
the resistor terminals to equal any signal received 
over the network from another transmitter. This 
 
 
signal will be applied to the operational amplifier, 
and in turn, to the receiver portion of the trans­
ceiver.

Abstract: In an electric switching device (1), particularly constructed as a temperature regulator, the resilient switching arm (14) controlled by a hydraulic expansion cell (12) for operating a snap switch (5) is fixed by means of positively engaging snap connections (32) to plate-like support parts (20) of a sheet metal support body (3) of a body (2), the support parts (20) on either side of the switching arm (14) being at right angles to joint axis (25) of arm (14) as lateral bends to a base plate (30) of support body (3) and receive between them an end portion of an insulator (4) carrying the switch (5). This leads to an extremely favourable taking up of forces, so that the support body (3) can be made from extremely thin sheet metal as a relatively elastic component. It also leads to a very simple assembly of the switching arm (14).
