Title: Device for dragging along trunks or suchlike
IPC: B66D1/36
Filed: 1988-01-13
Abstract: In a known device of this type, a pivotable arm is arranged on a timber-moving machine designed as a track-laying vehicle, which arm acts as a tightening device for a traction rope on which the timber to be moved is transported in the manner of a cableway. The novel device is intended to allow logs or suchlike, preferably arranged in lanes, to be moved in a simple fashion without it being necessary for the log-moving vehicle to be displaced from lane to lane. The device which can be built onto a log-moving vehicle or suchlike has an arm for the traction rope, which arm is arranged, on a transverse bar which can be connected to the lifting device, the three-point suspension or the like of the log-moving vehicle, in such a manner that it can be pivoted about a horizontal axis, and supporting legs for supporting the transverse bar on the ground are arranged at its faces. <IMAGE>

Patent EP-0299631-A3 (EP)
IPC: A61M35/00
Filed: 1988-06-20
Abstract: Methods and apparatus for administering known 
quantites of medicaments by iontophoresis, while avoiding 
burns caused by extremes in the pH of the medicament medium 
during passage of an electric current, are disclosed. It is 
known that as iontophoresis progresses in conventional 
iontophoresis systems, the electrolysis of water occurs to 
produce hydrogen or hydroxyl ions at the interface of the 
electrode and medicament medium.  
In addition, the efficiency of iontophoresis decreases 
over time. The present invention avoids extremes 
in pH by removing the hydrogen or hydroxyl ions which are 
created during iontophoresis and creates conditions for 
constant delivery over prolonged periods of time.  
     In the present invention, the medicament medium 
adjacent the patient is periodically or constantly replaced 
by adding fresh medicament medium which is at the original 
pH. The present invention also discloses a flow-through 
electrode which allows new solution to constantly flow into 
the iontophoresis area.

Patent EP-0300768-A3 (EP)
Title: Fuse clip assembly
IPC: H01R13/115
Filed: 1988-07-20
Abstract: The present specification discloses a fuse clip 
assembly (11,12) for use primarily but not exclusively 
in a vehicle electrical system fuse box. The assembly 
comprises a bus bar (11) with a number of terminals (14) 
to which an electrical connection is made by a clip 
arrangement (22,24). The clip arrangements in known bus 
bars (11) are formed by stamping and folding the 
material of the bus bars (11) and this therefore limits 
the minimum spacing between the terminals (14) and 
limits the minimum overall size of the assembly.  
     The present invention provides a fuse clip assembly 
comprising an elongate bus bar (11) having integral 
therewith a plurality of juxtaposed parallel blade 
terminals (14) extending transverse to the length of the 
bus bar (11), and a plurality of fuse clips (12). Each 
fuse clip (12) has a fuse engaging portion (21) and an 
integral socket terminal portion (22), each fuse clip 
(12) being carried by and electrically connected to the 
bus bar (11) by engagement of a respective blade 
terminal (14) in a socket terminal portion (22). Thus, 
as the bus bar (11) only has blade terminals, the length 
of the assembly can be more readily minimised.

IPC: H04N1/40
Filed: 1988-08-17
Abstract: A half-tone image reproduction apparatus, which 
comprises a Dither matrix memory (12), constituted by a 
plurality of elements, for storing a multi-level Dither 
matrix having multi threshold levels assigned to the 
individual elements, input data supplying means (10, 11) 
for supplying the element on the Dither matrix (12) and 
an input density level, and print dot forming means (13, 
14) for forming print dots in accordance with the energy 
control level selectively read out from the Dither 
matrix memory (12). The energy control level stored 
in the Dither matrix memory (12) is set in accordance 
with rules for changing the energy control level in 
accordance with a change in input density level. These 
rules are independently suitably determined for the 
respective partial density ranges which constitute a 
whole density range for the input density. According 
to this invention, gradation jump and deformation at a 
high density region can be prevented so that a half-tone 
image with smooth gradation and high resolution can be 
attained.

Title: Folded/telescoped drill rig mast for limited space platform
IPC: E21B15/00
Filed: 1988-10-11
Abstract: A folding telescoped drill rig mast (10) having 
wheel assemblies which travel along the power swivel 
guide rail to guide the telescoped upper mast (39) as 
it retracts or extends within the lower mast (30). 
The fully extended upper mast (39) locks into a transfer 
frame (70) which moves laterally relative to the lower 
mast (30) between a first position with the upper guide 
rail (72) offset from the lower guide rail (52) to a 
second position with the upper guide rail (72) in 
longitudinal alignment with the lower guide rail (52). 
This lateral movement aligning the upper and lower masts 
(39, 30) enables pinning the upper and lower masts 
together to transfer the upper mast loading to the support 
members of the lower mast. The mast includes a base 
structure (33), a lower mast (30) with a guide rail 
(52), and an upper mast (39) held within the lower mast 
(30). The upper mast (39) includes a guide rail (72) 
for the power swivel. A dolly wheel assembly (85, 86) 
mounts to the upper mast (39) and engages the lower 
guide rail (52) to guide the upper mast (39) as it travels 
between a first position within the lower mast (30) 
to a second extended position. A transfer frame (70) 
at the free end of the lower mast (30) connects rigidly 
to the upper mast (39). The transfer frame (70) and 
the upper mast (39) are moved laterally relative to 
the lower mast (30) to align the upper and lower masts 
(39, 30) and the upper and lower power swivel guide 
rails (72, 52).
Patent EP-0319225-A3 (EP)
Title: Method and apparatus for linear combination weighing
IPC: G01G19/393
Filed: 1988-11-28
Abstract: A combination weighing apparatus (10) and 
method are provided particularly adapted for, 
utilization with difficult to handle product. A series 
of in-line transfer conveyors (12) form product feed 
lanes with individual volumetric cups (22) designed to 
receive and hold a product charge (C). A scale (S) and 
weighing hopper (38) is associated with each transfer 
conveyor (12). The transfer conveyors (12) are each 
advanced in stepped fashion so as to deliver a product 
charge (C) from one volumetric cup (22) at any single 
time to the associated weighing hopper (38). A washer 
unit (40) cleans residue and the product buildup from 
the cups (22) after delivery of the product charge (C). 
Once the product charge (C) is delivered to the 
weighing hopper (38), the weight of the charge is 
registered by a control unit (44). The control unit 
(44) scans various combinations of scales (S), 
calculates the total weight of product in the 
combination and selects the first combination that 
falls within an acceptable range above the target 
weight. The product charges (C) are then delivered in 
timed relation to a plate (P) as it advances along a 
conveyor (46) beneath the scale hoppers (38). In 
accordance with an important aspect of the present 
invention a feedback mechanism (86,88) is provided for 
indicating the weight trend of product charges (C) 
being delivered to the volumetric cups (22). As long 
as the charge weights fall within a preselected range, 
the quality of charges from which the control unit (44) 
selects is maintained at a high level so as to allow 
maximum operating efficiency.

the polymer as an integral part of the polymer chain 
and absorb ultraviolet radiation in the range of 
about 250 to about 390 nm. The residues are non-­
extractable from the polymer and stable at the 
conditions at which the polymers are manufactured and 
processed.
