Title: Primary polyether active hydrogen compounds and process for preparing the same
IPC: C08G65/12
Filed: 1989-07-28
Abstract: Polyether active hydrogen compounds having at 
least two terminal active hydrogen groups on primary 
carbon atoms are prepared by (a) forming polyoxyalkylene 
molecules each having at least one active hydrogen 
precursor, (b) linking at least two of the 
polyoxyalkylene molecules, and (c) converting the active 
hydrogen precursor groups to active hydrogen groups on 
primary carbon atoms. The polyoxyalkylene molecule is 
formed by exposing a reaction mixture comprising at 
least one alkylene oxide and at least one protective 
initiator to conditions effective for the polymerization 
of the alkylene oxides. Linking is accomplished at 
polyether chain ends distal to the protected active 
hydrogen precursor groups, such that the active hydrogen 
precursors remain on the linked polyether chains until 
they are converted to active hydrogen groups. The 
process is particularly useful to produce polyether 
compounds having at least 80 mole percent primary active 
hydrogen groups, which compounds are useful, for 
instance, in forming polyurethanes.

Title: Crt socket
IPC: H01R33/76
Filed: 1989-08-14
Abstract: Disclosed is a CRT socket comprising a socket housing, a 
focus connection contact and a focus spark-gap contact, which has 
a snap-in terminal to connect to a high-voltage lead conductor. 
This snap-in terminal is composed of stationary and movable con­
tact pieces. The socket housing has a spark electrode compart­
ment and a socket cover. The socket cover has a hollow casing to 
contain the snap-in terminal of the focus spark-gap contact and a 
press-fit cover to close the hollow casing. The press-fit cover 
has a projection to enter the hollow casing and push the movable 
contact piece against the stationary contact piece when closing 
the hollow casing. This CRT socket structure permits first, 
checking by sight of the connection of a high-voltage lead con­
ductor to the focus spark-gap contact, and second, easy removal 
of the high-voltage lead conductor from the CRT socket for main­
tenance or checking simply by opening the press-fit cover.

Title: Injection molding machine
Inventor: KAMADA KOICHI
IPC: B29C45/38
Filed: 1989-09-26
Abstract: An injection molding machine employing a mold for molding, e.g., disk-shaped recording medium carriers. A mold-mounting plate (1) has a front surface allowing the mold to be the mounted thereon. A gate-cutting punch (4) is slidably inserted in a hole extending through the plate (1) and opening in the front and rear surfaces of the plate (1). A bore extends longitudinally in the center of the punch (4), and an ejector pin (5) is slidably inserted in the bore. A gate-cutting drive cylinder (6) is mounted on the rear surface of the mold-mounting plate (1), and has a piston (8) capable of abutting against the rear end of the gate-cutting punch (4). The piston(8) is formed with a stepped bore having a large-diameter front portion and a small-diameter rear portion (12) which are aligned on the same axial line. An ejector rod (13) extends through the stepped bore, and has a large-diameter portion (14) slidable within the large-diameter portion of the stepped bore, the front end of the ejector rod (13) being capable of abutting against the rear end of the ejector pin (5). A sprue-ejecting drive cylinder (18) is provided behind the gate-cutting drive cylinder (6) on the same axial line, and has a piston rod (23) connected to the rear end of the ejector rod (13). Thus, the machine includes no hydraulic cylinders incorporated in the mold, thereby eliminating various drawbacks conventionally encountered.

Abstract: A brake control apparatus includes a bracket (3), a 
brake lever (4) pivoted to the bracket via a lever shaft (5) 
and a lever spring (6) for urging the brake lever to its 
home position relative to the bracket. The lever 
spring has first and second spring legs (62,63) engageable 
respectively with the bracket and the brake lever and a 
coil portion (61) disposed between the first and second 
spring legs. A return movement of the brake lever to 
its home position relative to the bracket is realized 
by flexion of a radial center line of the coil portion 
of the lever spring. With this control apparatus, the 
lever spring can provide substantially constant urging 
force regardless of the pivot amount of the brake 
lever and the lever spring does not produce unpleasant 
creaking noise in the course of a braking operation.

IPC: A43B17/16
Filed: 1989-11-09
Abstract: An orthotic footwear insert (11) is made of a resilient shock-ab­
sorbing layer (12). The layer has an upper surface (27), intended to 
receive the heel, the upper surface having a plurality of outwardly pro­
jecting nodules (21) arranged in a waffle-like pattern which defines the 
upper plane. The layer also has a lower surface, beneath the heel-­
receiving surface. The lower surface has a plurality of rib members 
extending longitudinally between the back and front edges (15, 17)) and 
generally parallel to the side edges (13) of the layer. The rib members 
are therefore arranged such that air does not become trapped between them 
when pressure is applied to the layer. The invention also includes a 
method of making a shock-absorbing composition, which can be used to con­
struct the footwear insert or other products. The 
composition is extremely strong and resilient, and can be formed into 
virtually any shape. Thus, the composition is not limited to use in 
footwear, but can be used in any application requiring resiliency and 
shock-absorbency.

Abstract: A spark plug grinding machine is equipped 
with force sensors (24) to measure grinding forces 
and other forces attendant to a grinding operation. 
Ceramic spark plug insulators (14) are carried by 
spindles (12) on a Ferris wheel (10) into a grinding 
station. A control wheel (20) engages and spins each 
insulator as a grinding wheel (22) grinds the surface 
of the insulator. A three axis transducer (24) on 
one of the spindles measures force components along 
the axis of the spindle, parallel to a tangent of the 
grinding wheel and in a radial direction. A torque 
sensor (46) on the control wheel measures the torque 
as the wheel rotates each insulator. Either or both 
of the sensors may be used. They are coupled through 
slip rings (30,56) to a recorder (32).

Title: Procedure and device for deviating a beam
IPC: H01J37/147
Filed: 1990-08-27
Abstract: In order to utilize a magnet arrangement having a magnetic flux density field for beam guidance in the deflection of a beam of monopolar charged particles, regions of the field having curved field lines, are modified to significantly linearize the field lines in the area of the beam. An additional flux density field is superimposed on the primary flux density field so that the field lines interact in an harmonic synthesis and so that the field lines of the resulting field in the region of interest, extend linearly. In this way, the deflection force on the beam is essentially independent of the beam position in the field direction and in the linearized region.

Title: Distributed feedback laser for frequency modulated communication systems
IPC: H01S5/12
Filed: 1990-01-18
Abstract: To overcome the deleterious effects of the nonuniform frequency 
modulation response in semiconductor lasers due to current injection in direct 
frequency modulation applications, it has been determined that the linewidth 
enhancement factor α be made as large as possible. In one embodiment, distributed 
feedback lasers well suited for frequency modulation lightwave communication 
systems are designed to have an integrated feedback element such as a corrugation 
grating whose effective pitch is selected to cause the Bragg wavelength and, 
therefore, the laser operating wavelength to be longer than the wavelength at 
substantially the maximum gain or gain peak in the semiconductor structure without 
the grating. That is, the wavelength of the grating is effectively detuned toward the 
longer wavelength and lower energy side of the peak of the gain profile. Such 
detuning increases the linewidth enhancement factor in such a way that the 
nonuniform frequency modulation response and its effects are minimized and, in 
some cases, substantially eliminated.

Title: Elongate flexible elements particularly for use as glazing strips
IPC: E06B3/62
Filed: 1990-01-30
Abstract: An elongate flexible element for use as a 
glazing gasket comprises a main body (10) integrally 
formed with a tear-off strip (15) extending along the 
length thereof, the tear-off strip being connected to 
the main body (10) by a zone which may be readily

main body. The effective thickness of the glazing strip 
may therefore be reduced, if required, by removing the 
tear-off strip (15). Adjacent the rupturable zone there 
is integrally formed with the gasket an elongate strip 
(18) of material which is harder and less flexible than 
the material of the main body and tear-off strip, so as 
to facilitate the tearing-off of the strip (15).
Patent EP-0386985-A3 (EP)
IPC: H04B1/707
Filed: 1990-03-06
Abstract: For sampling a modulated carrier, a zero-crossing detection 
means having two independent control loops, a first loop for a zero-­
mean threshold control and a second loop for AGC control includes an 
IF sampler (14) that quantizes the received spread spectrum signals 
at IF and samples at a number of quarter cycle intervals to allow 
sampling in sequence of the in-phase (I) and quadrature-phase (Q) 
components. The output of the IF sampler (14) is two bits, a sign 
bit and a magnitude bit. The zero-mean threshold control loop (16, 
18) using only the sign bit of the I and Q samples sets a threshold 
level (T0) to detect the zero-crossings of a received waveform. Two 
magnitude threshold levels (TO+D1, TO-D2) are set at fixed offsets 
from the T0 threshold level. A normalized statistical accumulator 
(26) using the magnitude bits of the I and Q samples determines the 
AGC control level for a fixed percentage of outside threshold 
crossings of the most significant magnitude bit. The I and Q 
samples are aligned in time by an aligner (16), and every other pair 
of I and Q samples are inverted in a baseband demodulator (20) for 
digital demodulation of the IF samples to baseband. The baseband 
samples are provided to a signal processor (24) for generating range 
and range rate information.
