Title: Method to suppress amplitude variations of two alternating, periodic signals in phase quadrature with a random phase sequence, and circuit arrangement to carry out the method
IPC: G05F1/45
Filed: 1989-12-08
Abstract: The invention relates to a method of suppressing amplitude variations of two electrical signals (uS1, uS2) in phase quadrature and a circuit arrangement for carrying out the method. According to the invention, the positive or negative amplitude variation of the signals (uS1, uS2) is monitored for undershooting of a lower or overshooting of an upper reference voltage (+/-US- or +/-US+) in such a way that in the event of undershooting or overshooting a device (20, 22) for changing a prescribed manipulated variable of an actuator (8, 10) is activated, and the signals (uS1, uS2) are respectively converted into rectangular signals (uRS1,uRS2), from which clock pulses (uC11 or uC12) are generated by means of a logic circuit (24 or 26) depending upon the phase sequence of the signals (uS1, uS2) at the positive or negative flanks of the rectangular signals (uRS1, uRS2), which vary the prescribed gain as a function of the result of the amplitude monitoring by a prescribed value (LSB). This yields a method of suppressing amplitude variations of two electrical alternating, periodic signals (uS1, uS2) in phase quadrature with a random phase sequence, and a circuit arrangement for carrying out the method that operates independently of frequency.   <IMAGE>

Title: A digital signal recording apparatus
IPC: G11B27/032
Filed: 1989-05-31
Abstract: The present invention is concerned with a signal 
recording device adapted for recording signals on a recording

Patent EP-0344138-A3 (EP)
Title: Secure personnel monitoring system
IPC: G08B25/10
Filed: 1989-05-18
Abstract: A personnel monitoring system includes a tag (60) worn by each monitored person. The tag repeatedly emits digital radio signals, and a predetermined bit in the signal changes with time according to a predetermined pattern. Monitoring apparatus (12) detects the radio signals and sends an absence alarm signal if the signals cease. The monitoring apparatus detects spurious, forged signals which do not replicate the predetermined pattern of variation and provides a forgery alarm signal. The tag may be attached to the person by a strap bearing parallel electrical conductors. Attempts to remove the tag by severing the strap cause electrical contact between the conductors. Such contact triggers a detector, which in turn alters the radio signal.

Title: Automatic adjusting circuit for an analog filter
IPC: H03H11/04
Filed: 1990-02-15
Abstract: The center frequency (fo) of each of the analog 
filters (1, 2) with different selectivities each other 
installed in an automatic adjusting circuit is automati­
cally adjusted in accordance with a bias input signal 
(Sb) which is generated by the phases detectors (3, 4) 
respectively associated with the analog filters (1, 2) 
in accordance with a frequency difference, so as to be 
equal to the reference frequency (fs) of an input signal 
(Si) applied to the two analog filters (1, 2). The bias 
input signal (Sb) is fed to an analog filter (31, 32, 
...) to be controlled, which is formed on the same chip 
as that of the above two filters (1, 2). A coarse 
adjustment is based on the output signal of the phase 
detector (3) associated with the analog filter (1) with 
a low selectivity. A fine adjustment is based on the 
output signal of the phase detector (4) associated with 
the analog filter (2) with a high selectivity. An 
accuracy of matching the center frequency to the 
reference frequency is determined by both the selec­
tivity of the analog filter (2) with a high selectivity 
and the ratio of the output signals of the two phase 
detectors (3, 4) in the automatic adjusting circuit.

Title: Process for obtaining polyurethane compounds containing granules of cork or similar substances, particularly for the manufacture of soles for footwear, apparatus for realising this process, and the product so obtained
IPC: B27N1/02
Filed: 1990-08-01
Abstract: This procedure refers to the incorporation of granules of cork or similar substances into polyurethane products. The polyurethane components and the cork (or similar) granules are introduced simultaneously into a suitable mixing chamber (26), the granules being suitably dosed by variable speed programmable screw conveyors (or otherwise, for example pneumatic feeds, mechanical pistons, etc.). The conglomerate as above is introduced, while still in the early stages of reaction, into fixed or moveable moulds (40) or dies by gravity (with the mould open), or by injection (with the mould closed), and completes its reaction there, forming the product in times which vary according to the characteristics of the mixture used and the shape of the article produced. The moulds or dies are preferably kept at a temperature of about 50 DEG C, though this is not critical since this factor also varies widely according to the polyurethanes used and the pieces being produced.

Title: Screwable plate for fracture treatment of the dentiform axis apophyse
IPC: A61B17/80
Filed: 1991-05-21
Abstract: A plate (1) is designed to be positioned on the caudal fragment (2) of the axis (C2) and to bear thereon. It serves as a bearing surface for the head (13) of a screw (12) and as a positive guide for the screw via a gun (11). The end of the screw (12) is screwed into the cranial fragment (3) of the odontoid apophysis (tooth) of the axis (C2). The plate (1) is continued on the caudal side by a fork-shaped part (14) bearing on the anterior surface of the body of the third cervical vertebra (C3). The invention prevents the head (13) of the screw (12) from penetrating into the caudal fragment (2) of the axis (C2) and prevents the self-tapping screw (12) from scavenging this friable caudal fragment (2) before becoming positively engaged in the cranial cortical fragment (3). <IMAGE>

Title: Surgical purse string suturing instrument and method.
Inventor: ALLEN WILLIAM J
IPC: A61B17/04
Filed: 1993-02-26
Abstract: A purse string suturing instrument is provided for quickly and effectively forming a purse string suture in tubular tissue through relatively small cannulas placed in the body. The instrument includes a pair of elongated jaws (12,14), each having a row of spaced-apart uniform-size teeth (16,18). The jaws (12,14) are hinged together at one end to clamp the tubular tissue therebetween. The two rows of teeth (16,18) are offset with respect to each other so that they mesh when the jaws (12,14) are closed. The jaws (12,14) are inserted through a cannula and positioned to close around the tissue to be sutured. The rows of teeth (16,18) then bend the tissue between them into a wavelike configuration. A pair of needles (56), the ends of each being connected to a single length of suture, is then inserted through passageways provided through the teeth (16,18). An encircling series of stitches are thus formed in the wall of the tubular tissue to create a purse string suture. The needles (56) and the suturing instrument are then withdrawn through the cannula. The tubular tissue can be snugly fitted over an anastomosis ring or the like by drawing and tying the purse string suture.
