G is a divalent radical remaining after 
removal of terminal hydroxyl groups from a 
poly(alkylene oxide) glycol having a carbon-to-oxygen 
ratio of about 2.0-4.3 and a molecular weight of about 
600-6000;  
R is a divalent radical remaining after 
removal of carboxyl groups from a dicarboxylic acid 
having a molecular weight less than about 300;  
 
 
D is a divalent radical remaining after

2-8 carbon atoms and represented by the formula 
HO(CH₂)₂₋₈OH or the diol HO(CH₂CH=CHCH₂)OH;and  
T is a trivalent radical remaining after the 
removal of carboxyl groups from a tricarboxylic acid 
having a molecular weight less than about 350 and 
containing two vicinal carboxyl groups capable of 
forming a cyclic imide;  
with the proviso that the short chain ester 
units constitute about 30-65% by weight of the 
copolyester, at least about 50% of the R groups are 
1,4-phenylene radicals, at least about 50% of the D 
groups are 1,6-hexamethylene radicals, and the sum of

Title: Temperature measuring sensor arrangement
IPC: G01K1/14
Filed: 1989-05-23
Abstract: A temperature measuring sensor arrangement is described, which 
can be inserted into or removed from an enamelled built in 
part in a simple manner without a need for specific tools. 
A measuring insert with a carrier is provided, along the 
length of which an outwardly protruding detent element in the 
form of a collar is provided, and from the lower end surface 
of which carrier one or several measuring sensors are protru­
ding. The carrier is slidably arranged in a longitudinal 
direction in a guiding tube and is biased downwardly by a 
spring engaging between the detent element and a shoulder 
in the guiding tube. A stop protruding from the inner wall 
of the guiding tube limits the displacement of the biased 
carrier. The guiding tube is fixedly mounted at the upper end 
protruding from the built in part by means of a wedge ring-­
screwed joint in the inserted position, in which the detent 
element is raised from the stop and the ends of the measuring 
sensors are pressed against a surface formed at the 
enamelled built in part over a thin walled bottom region. The 
bottom region is provided with an upwardly extending conical 
enlargement for the insert end of the guiding tube. Pre­
ferably the thin walled bottom region is provided with a 
coating out of silver.

Title: Screed rails
IPC: E01C9/00
Filed: 1985-07-01
Abstract: A method of casting an horizontal area of concrete comprises laying a pattern of screed rails (2,30,48) on a substrate (46) with the rails supported in shoes (8,34,60,68) on the substrate (46) at spaced locations therealong to define at least one casting region in the pattern. Concrete is cast in the region or regions to cover the area. The rails (2,30,48) may be supported above the substrate (46) to form spaces between the rails and the substrate. The rails (2,30,48) may be located in the shoes (8,34,60,68) by means of one or more of spacers, wedges and bolts (12,14,36,40).
Patent EP-0359173-A3 (EP)
Title: Camera apparatus for magnetically encoding a film leader
IPC: G03B17/18
Filed: 1989-09-11
Abstract: When a filmstrip (F) is completely exposed 
in a camera (101), double-exposure prevention DEP 
data is magnetically applied to the film leader (43) 
substantially immediately before the leader is 
rewound with the filmstrip into a light-tight 
cassette (1). The DEP data indicates there are no 
unexposed imaging areas remaining on the filmstrip. 
If the filmstrip is rewound into the cassette 
prematurely, i.e. without it being completely 
exposed, midroll interrupt MRI data is magnetically 
applied to the film leader instead of the DEP data 
to indicate the next-available unexposed imaging 
area of the filmstrip. When the cassette is 
re-loaded into the camera, the film leader is 
advanced from the cassette initially to determine 
whether it is encoded with DEP or MRI data. If the 
DEP data is detected, the leader is rewound into the 
cassette since all of the imaging areas of the 
filmstrip are exposed. If the MRI data is detected, 
the filmstrip is advanced from the cassette to 
locate the next-available unexposed imaging area in 
an exposure position. Warning means (149, 151), 
responsive to the sensing of the DEP data or the MRI 
data, provides a visible and/or audible signal that 
a completely used or partially used film roll has 
been loaded in the camera.

Title: Apparatus and method for determining the permittivity of samples of material over a wide frequency band
IPC: G01R27/26
Filed: 1989-04-27
Abstract: Measurements of the permittivity of samples over a very wide 
frequency range and a wide temperature range have previously 
involved such problems as changing parts of the measuring equipment 
in different regions of the frequency range, substituting one of 
the components of a bridge used as part of the equipment to obtain 
bridge balance, and limited permittivity resolution. The present 
invention employs a capacitance bridge formed by a sample (C₁,R₁) 
held between electrodes, a series capacitor C₂ and a detector 
comprising a high input impedance amplifier 11 and correlators 25. 
The bridge is balanced by applying voltages of known relative 
amplitude and phase constructed from outputs having relative phases 
of 0°, 90° and 180° of two phase-locked oscillators 13 and 14. 
The voltages are constructed using phase shifters 17, 20, 
attenuators 19, 21 and summer-driver circuits 12, 22. At low 
frequencies the applied voltages are obtained from a waveform 
synthesizer 15. In order to allow for any inaccuracies in the 
amplitude and phase of the applied voltages, a reference bridge is 
provided which comprises two capacitors 26, 27 connected in series 
and a detector which includes a high input impedance amplifier 28, 
connected between the junction of the capacitors and a common 
terminal.

with a suitable barrier. The foodstuffs can then be heated 
by microwaves after removal of the barrier seal and without 
the need for a further container

Title: Child's shoe
IPC: A43B23/02
Filed: 1989-11-01
Abstract: A split-sole shoe (40) has a front outer sole 
(15) with an outwardly facing recessed section (18) and 
a heel member (30) with an inwardly facing recessed 
section (35), the outwardly facing recessed section (35) 
being connected to the inwardly facing recessed section 
(35) in an overlapping configuration so as to form an 
interior relief groove exposing a portion of the 
inwardly facing recessed section (35) and an exterior 
relief groove exposing a portion of the outwardly facing 
recessed section (18), thereby increasing the 
flexibility of the shoe in the region which flexes while 
taking a heel-to-toe step. A toe cap portion (11, 12, 
13, 14) is formed together with the front outer sole 
(15) so as to provide a smooth and continuous transition 
from the top of the toe cap to the bottom of the front 
outer sole, thereby enabling an infant or child to drag 
the toe cap portion (11, 12, 13, 14) of the shoe without 
stumbling or tripping on a protuberance in the 
transition region. The bottom surface (17) of the front 
outer sole (10) is made from a material having a 
coefficient of friction which is lower than that of the 
material on the bottom surface (32) of the heel 
member (30).

Abstract: A pair of conductive strips 9, 10 in a waveguide, for 
example, defining a fin-line transmission line insert 
have a switching element such as a PIN diode 11 
connected to them to reflect or pass r.f. energy in 
the fin-line section. The switching element 11 forms 
part of a filter circuit, for example, in conjunction

of which is matched to that of the gap. When the PIN 
diode is forward biased, the strips 9, 10 are in effect 
short circuited and the r.f. energy is reflected. 
When the diode is reverse biased, the r.f. energy 
passes without reflections. Due to the matching of the 
impedances this obtains over a broad bandwidth.

secured in place about the skis in the locked position. 
The body member is additionally provided with a shallow 
longitudinal flange depending from the underside thereof 
which is adapted to be disposed between portions of the 
skis secured to the device by the securement strap (18) to 
prevent any lateral rotation of the carrying device with
