Title: Power Transistor Protection
Inventor: SIKKA JOGINDER
IPC: H03K17/00
Filed: 1983-04-22
Abstract: A device for protecting a power transistor (Q6) against overload current includes a resistor R18, a comparator A1 receiving on its non-inverting input a voltage which is proportional to the current flowing in the resistor R18, and on its inverting input a reference voltage derived from a zener diode Z1 and a resistor chain R9, R10, a transistor Q2 for shunting the base electrode of the power transistor Q6, and a circuit including transistors Q3, Q4 operable from the output of the comparator A1 for turning on the shunting transistor Q2 when the voltage across the resistor (R18) exceeds the reference voltage. Transistors Q3 and Q4 function to raise the value of the voltage at the inverting input of comparator A1 once the comparator has detected overload of the power transistor Q6 so that the shunting transistor Q2 remains conductive even though the current through the power transistor is reduced. The comparator may be formed as a differential amplifier (Fig. 2) including an emitter coupled pair of transistors (Q7, Q8). In a further embodiment (Fig. 3) in which Q4 and Q5 are omitted on current overload the power transistor Q6 is not completely turned off and Q3 conducts to reduce the reference voltage (V2) applied to the inverting input of the differential amplifier (Q7, Q8) so that the shunting transistor Q2 remains on. The device is applicable to electronic ignition circuits for internal combustion engines. <IMAGE>

Title: Optical fibre laser gyro
Inventor: KAJIOKA HIROSHI
IPC: G01C19/64
Filed: 1983-05-11
Abstract: Polarised light from a laser 11 is split at 15 into orthogonally polarised beams 15a and 15b incident on respective ends of a loop 16 of single polarisation optical fibre. After the transmitted beams have been recombined at 15, their relative phase is determined using a g DIVIDED 4 plate 17, analyser 18 and detector 19. Alternatively the recombined beams may be directed via a g DIVIDED 4 plate and a further polarising beam splitter to two photodetectors connected to the imputs of a differential amplifier, or the single detector 19 may be in a nulling loop where it controls a Pockels and Faraday element acting on the recombined beams. Polarising splitter 15 may be replaced by an ordinary splitter if one end of coil 16 is preceded by a 45 DEG  rotation Faraday element. <IMAGE>

Filed: 1983-06-06
Abstract: An explosion- or flame-proof electrical coupling comprises a plug 16 provided with contact pins 54 to be received in bushes 20 in a socket, the plug having a cylindrical collar 140 formed with an internal annular surface which, following insertion of the plug into the socket, surrounds an annular surface on the socket so as to form an air gap 150. A shutter ring 48 having openings 56 correspond in number to the bushes 20 is provided in the socket 14 to cover the bushes 20 before insertion of the plug into the socket and is locked in this position by spring-urged pins 68 engaging in the openings 56. To insert the plug into the socket, the plug is moved axially so that the pins 54 engage in the openings 56 to displace the locking pins 68. The plug and, therefore, the disc 48 is rotated to align the pins 54 with the bushes 20 and, finally, the plug 16 is moved axially. In one embodiment, this movement is guided by a radial lug on the collar 140 engaging in a first axial groove, a part- circular groove and a second axial groove offset from the first groove. <IMAGE>

Title: Sterilisation of milk
Inventor: GREENER FRANK WALTER GEORGE
IPC: A23C3/07
Filed: 1983-09-28
Abstract: Milk is sterilised by spraying it through a zone traversed by bactericidal radiation, more especially comprising heating radiation e.g. infra-red rays. The conditions are adjusted or selected, so that the bacteria in the spray are heated to a killing temperature while the fat globules of the spray are heated to a lower temperature, not liable to affect the taste of the milk. The spray may follow an upward flow path and it may be subjected to sonic or ultrasonic vibrations. It may be cooled on leaving the heated zone. The radiation may be interrupted, e.g. by means of a rotating sputter or rotating reflector.

Title: Improvements relating to expansion bolts
Inventor: LECOURT NOEL
IPC: E04G23/02
Filed: 1983-12-19
Abstract: An expansion bolt uses one or more coil springs (34, fig. 8) which, as they are axially compressed, are caused to expand radially at their ends to clamp against a bore. The ends of the springs engage over frustoconical abutments (; 33, 35) which are backed by a nut or bolt head and a member whose external formation is such that its engagement with the bore prevents it rotating, but allows it to move axially. A particular application is to a wall tie (Fig. 1) where springs (8) are fitted on threaded portions (3, 4) of opposite hands at opposite ends of a rod. Each spring is twisted in the same way as the associated screw thread. The rod (1) can be turned to cause one spring to clamp first, and then a nut (10) on the other screw threaded portion (4) can be turned to clamp the other spring. It can also be arranged that both springs are compressed and their ends radially expanded simultaneously. In a further alternative one of the springs is replaced by a setting material, and projections 20 (Fig. 6) are provided for keying into this material. <IMAGE>

Title: Improvements relating to swimming pool covers and the like
Inventor: BOYD HARRY OSBORN
IPC: F24J2/04
Filed: 1984-07-27
Abstract: A cover for a swimming pool comprises an upper layer 2 defining water channels 3 and secured to a lower layer which provides insulation and buoyancy. Water may be pumped into the channels 3 through a pipe 4 and will pass along these channels and in the process will be heated by solar energy absorbed by the dark upper layer 2. The heated water will then pass out through the ends of the channels back into the pool. The lower layer is ideally formed from a flexible closed cell polyurethane foam which will support the cover on the top of the pool and also act as an insulating cover during the night. When not required the cover can be rolled up onto a roller 5 to which it is attached by means of straps 6. <IMAGE>

Title: Macroscopically expanded three-dimensional polymeric web and an absorbent bandage containing said web
Inventor: OUELLETTE WILLIAM ROBERT
IPC: A61F13/49
Filed: 1986-05-30
Abstract: A macroscopically expanded, three-dimensional fluid-handling polymeric web having first and second surfaces located in substantially parallel planes which are remote from one another. The web includes a multiplicity offluid-handling capillary networks of macroscopic cross-section for rapidly transmitting fluids which are dynamically deposited on the first surface of said web to the second surface of said web using the dynamic and gravitational head of the fluid as a primary driving force. Each of the macroscopic cross-section capillary networks originates as an aperture in the first surface of the web and has a continuously interconnected sidewall extending in the direction of the second surface of said web. The continuously interconnected sidewall terminates to form at least one aperture in the second surface of said web, whereby the bulk of the dynamically deposited fluid is transmitted from the first surface to the second surface of said web by the macroscopic cross-section capillary networks. The first surface of the web in which the macroscopic cross-section capillary networks originate further includes a multiplicity of fluid-handling capillary networks which are substantially smaller in cross-section than the macroscopic cross-section fluid-handling capillary networks. The smaller fluid-handling capillary networks exhibit a degree of capillary suction sufficient to transmit static fluid contained on the surface of objectswhich contact the first surface of said web generally in the direction of the second surface of said web by capillary attraction. In a preferred embodiment the smaller fluid handling capillary networks are oppositely oriented from the macroscopic cross-section capillary networks to provide improved visual and tactile impression as well as to enhance the volume of dynamically deposited fluid which flows into the macroscopic cross-section capillary networks.
