Title: Polyurethane sealant compositions employing low molecular weight graft polymer dispersions
Inventor: CHRISTMAN DONALD LEE
IPC: C08G18/63
Filed: 1987-10-21
Abstract: Polyurethane sealant compositions are prepared by reacting (a) a low molecular weight graft polymer dispersion, (b) a polyether polyol, optionally pigment, catalyst and inorganic filler, and an organic polyisocyanate. The compositions are useful as thermal break sealants and in the manufacture of bowling balls. The graft polymer dispersion is prepared by polymerizing in the presence of a free radical initiator from 25 to 70% wt based on the total weight of the dispersion, an ethylenically unsaturated monomer(s) in a polyol mixture comprising (1) 25 to 99% wt of a polyol having 2 to 8 hydroxyl groups and an equivalent weight of 30 to 200, and (2) 1 to 75% wt of a macromer comprising the reaction product of a polyether polyol having an equivalent weight of 100 to 10,000 and a compound having both ethylenic unsaturation and a group selected from hydroxyl, caboxyl, anhydride, isocyanate and epoxy groups or mixtures thereof.

Title: A demodulator circuit for an interferometer type of hydrophone
Inventor: LAYTON MICHAEL R
IPC: H03D3/02
Filed: 1988-08-31
Abstract: The optical signal in a fiber optic interferometer (20) is phase modulated to provide a carrier signal for phase changes caused by changes in a physical parameter such as sound, being sensed. The signal is then demodulated to measure changes in the parameter. A crystal oscillator (52) frequency reference and passive filtering cause the circuit to have low phase noise. Digital phase shifters (96, 98) provide mixer references that have low phase noise and stable gain. The signal processing techniques used are applicable to sensor arrays using a single carrier excitation source, time demultiplexing of individual carrier signals and demodulation of each sensor carrier signal. This demodulator circuit is also applicable to frequency-multiplexed approaches, which utilize direct frequency modulation of the source slightly unbalanced interferometers, and electronic frequency-division multiplexing. The passive homodyne technique allows large linear dynamic range of about 100 dB so that both small and large amplitude signals commonly encountered in acoustic sensing applications may be observed with excellent fidelity. <IMAGE>

Title: An arc relay
Inventor: LAUNONEN MARKKU
IPC: H02H1/00
Filed: 1988-04-07
Abstract: The invention relates to an arc relay intended for detecting an arc possibly flashing up at one or more points (A to E) of a switchgear (1) and for extinguishing it by causing a circuit-breaker supplying current to the switchgear to be opened. The arc relay comprises a pickup sensor for collecting light; an optical fibre (3) connected to the pickup sensor for transmitting the collected light forwards along the fibre; a photosensor (7) connected to the end of the fibre (3); and an electronics unit (4) connected to the photosensor (7) for controlling the circuit-breaker in response to the detected arc. A major drawback of known arc relays utilizing a collector lens is that they become complicated and expensive with an increasing number of points to be monitored. The problem is solved by means of the invention in such a manner that the pickup sensor is formed by the transparent cladding surrounding the core of the fibre (3).

Title: Electrical handtool with power supply independent of the mains
Inventor: SCHNIZLER ALBRECHT
IPC: B23B45/02
Filed: 1989-12-22
Abstract: A protective switch 6 is automatically opened to disconnect a motor M of the handtool if either one of series-connected battery packs 5 has a low charge level. One battery pack 5 has a monitoring circuit wherein low battery voltage renders zener diode Z1 and transistor T11 non-conductive so that an LED D12 is illuminated and a transistor T12 turns off to open switch 6. Low voltage in the other battery similarly illuminates LED D22 and turns on a transistor T22 to open switch 6. Diodes D11 and D21 provide a latching arrangement to prevent the switch 6 being closed again as battery voltage recovers once the motor 6 has been disconnected. The battery packs fit in recesses in a lower end part of the handle of the tool (Figs 1, 2).

IPC: H04N11/04
Filed: 1991-04-15
Abstract: A composite colour video signal is separated into its luminance Y, and colour difference R-Y, B-Y components which are then time division multiplexed MUX and sent to data compression circuit 3 after A/D conversion 2. Compression circuit 3 subjects the multiplexed video signal to factorial code conversion followed by cubic conversion and factorial adaptive size comparison conversion to reduce the amount of data to audio bandwidth. The date is then stored temporarily in buffer 4 and passed to telephone lines via conventional equipment 5. An inverse process is used to reconstruct the input video signal. <IMAGE>

Title: Ostomy bag coupling
Inventor: BRIGGS PETER JAMES
IPC: A61F5/448
Filed: 1991-06-03
Abstract: An ostomy bag assembly comprises a bag and a fitment secured around the stoma the bag having a coupling in the form of a neck with an annular lip 17 which is insertable in a deformable collar 24 in the fitment. A resilient ring 50 embraces the collar and has projecting tabs 54 and 55 by which it can be tightened to deform the collar about the neck of the bag coupling. A ratchet mechanism is provided whereby notches 60 and 61 in the ring are shaped to receive a tooth 58 on a tongue 56. The ring is so sized that when the tooth engages notch 60 no significant pressure is applied to the collar but, on squeezing of the tabs, the tongue is pushed further through aperture 59 until the tooth engages notch 61 thereby locking the ring in its tightened state and deforming the collar inwardly. <IMAGE>

Title: Common control for paper-feed engagement and bail lifting in selective printers
Inventor: KAWAHARA YUUJI
IPC: B41J11/48
Filed: 1991-09-26
Abstract: As shown (Fig. 1) a printer has a rotary platen (2) driven by a motor (GN). A wheel (21) fast with the platen (2) is connectable, via a shiftable clutch wheel (51), to a driving train (61, 61b, 61a, 62a) for a paper-tractor. A paper bail (3a) is operated by a snail-cam (43b) fast with a wheel (43) which also bears a switch cam (43a). The clutch wheel (51) is mounted on a swinging arm (52) which is detained in either of its extreme positions by a toggle (55). Both the toggle (55) and the cam wheel (43) are operated from a separate motor (GM) via a wheel (58). Clockwise rotation of motor GM from a home position causes the snail-cam (43b) to engage the bail arm (4a) without the engagement of the toggle (55) with a clutch-operating cam (58a) on the wheel (58). Similarly, counterclockwise rotation of motor GM causes the cam (58a) to operate the toggle (55) without the snail-cam lifting the bail. The toggle (55) has an operating arm (55d) which is displaceable sideways after contact with the cam (58a) to allow the cam to pass it, whereby the toggle can be switched in either direction (ie by direct operation of the cam (58a) upon first contact, or upon reversed operation of the cam (58a) after passing). The coordination of the selection mechanism is achieved by a controller in response to inputs from sensor switches S1 and S2. <IMAGE>
