Patent GB-2175988-A (GB)
Title: Diffusive light-sources
Inventor: WOOLGAR ANTHONY JOHN
IPC: F21V9/08
Filed: 1985-05-28
Abstract: Low power diffusive light sources are necessary for use in the calibration of extremely sensitive light detectors. Unfortunately, the standard light sources commonly used are far too bright and powerful. The invention provides a novel type of low power source that is both neat and compact. It proposes an arrangement wherein light from a strong source on the equipment's optical axis is passed through a coaxial aperture 11 and diffusively reflected, off the flat rear surface 12r of a coaxial conical diffuser beyond the aperture, rearwardly onto a coaxial annular plane mirror 13r (to form an axial imaginary source) and there, via a diffuser-encircling coaxial conical mirror 13f (forming a coaxial ring source), onto the conical front surface of the diffuser 12f and thence generally axially and forwardly through an aperture 14 constituting a weak secondary source that is the desired low powered source. <IMAGE>

Title: Respiration monitor
Inventor: SMITH E S
IPC: A61B5/113
Filed: 1985-06-15
Abstract: A respiration monitor which is battery operated and suitable to detect the onset of apnoea in infants or post operative patients comprises a permanent magnet mounted resiliently relative to a Hall effect device which detects changes in magnetic field due to movements of the magnet caused by breathing. The sensing device is easily attached to the patient by an elasticated belt, together with associated monitoring electronics in which the sensor signal is compared with a floating reference level in a level detector which is connected through an AND gate 3 to prevent a timer 4 timing out while respiration signals are present. Cessation of respiratory movement for greater than 10 or 20 seconds is indicated by both audible and visual alarms 14 and 15. <IMAGE>

Title: Method and apparatus for destroying froth
Inventor: LEHNHAUSEN GUNTER
IPC: C12M1/21
Filed: 1985-07-23
Abstract: The invention relates to a turbo- impeller (20) for destroying the froth forming in fermenter tanks for example. For this purpose, the turbo-impeller (20) is disposed immediately in front of the outlet orifice (18) for the spent air as a result of which the froth is at least substantially prevented from being entrained by the spent air through the outlet orifice (18). The turbo-impeller (20) may be installed with a horizontal or vertical plane of rotation but can also be used, in particular, in an inclined position. <IMAGE>
Patent GB-2166422-A (GB)
Title: Screw-threaded closure-container assembly
Inventor: LUKER EDWARD
IPC: B65D41/04
Filed: 1985-11-04
Abstract: To achieve a screw-threaded container and closure having a non-backoff feature which locks the container and closure internally to avoid unwanted loosening, a plug type seal on the closure (14) is used in conjunction with a bead (20) on the inside of the neck (16) of the container (12). An annular flange (30) of the plug, having a downwardly converging cam surface (34), diverges outwards to provide an axially downward closing force against the bead (20) which seals and resists unscrewing of the closure from the container. <IMAGE>

Title: Gyroplanes or autogyros; rotor control
Inventor: WATTS JAMES ARTHUR
IPC: B64C27/41
Filed: 1985-12-04
Abstract: An autogyro has rotor blades carried by a rotor head mounted via a bore (12) on a support member (10) rotatable about a pitch axis (18) and independently rotatable about a roll axis (22) for control of the autogyro in pitch and roll respectively. The pitch and roll axes intersect one another in order to overcome the problem of rotation about one axis affecting the radius of rotation about the other axis. Means are provided to prevent rotation of the rotor head and support member about an axis orthogonal to both the pitch and roll axes, and comprise a spindle (24) parallel to axis (18) and supported to pivot about axis 18 by links (28). Head plates (14) on the autogyro body carry the spindle (16) defining the axis (18), and the pilot's control movements are applied to the end (40) of support member (10) via linkages not shown. <IMAGE>
Patent GB-2169459-A (GB)
Title: Switched lamp socket
Inventor: WILLIS COLIN TERENCE
IPC: H01R33/18
Filed: 1985-12-18
Abstract: A lamp socket has a pair of first contacts 20, 21 connected to the electrical supply and a corresponding pair of second electrical contacts 40, 41 for engagement by the terminals of a bayonet-type lamp bulb. Each contact is biased in a direction towards the lamp bulb. When no bulb is in the socket, the second contacts are isolated from the first contacts but when a lamp bulb is inserted into the sockets, the second contacts are caused to move into conducting engagement with the first contacts for normal use. When the lamp bulb is disengaged from the socket, the second contacts automatically move away from the first contacts and are therefore isolated thus avoiding an electric shock if touched. <IMAGE>

Title: Graft polymerisation of monomers on rubber
Inventor: SUKA MOTOSHI
IPC: C08F279/04
Filed: 1986-09-13
Abstract: A graft polymer for ABS resin manufacture or the ABS resin itself is produced. The production of the former comprises charging a polymerizer with a rubber latex having an average particle diameter of 0.2-0.4  mu m and a gel content of 70-80%, so that the content by weight of the rubbery component in the resulting graft polymer is at least 50%, and then separately adding a monomeric mixture of (A) an acrylic such as acrylonitrile or methyl methacrylate and (B) a vinyl aromatic compound such as styrene and a polymerization initiator in adequate amounts to maintain the specified rubber content by weight, continuously at rates equal to or lower than the rate at which the both monomers (A) and (B) diffuse and permeate into the rubber particles. The ABS resin is manufactured by dehydrating the above graft polymer by a screw press to a moisture content of about 10% or less, indirectly drying the polymer, and then blending the same with an acrylonitrile-styrene copolymer or the like in an amount about 2-4 times the polymer amount.

Title: A system for driving a brushless motor
Inventor: OKU HIROYUKI
IPC: H02P6/00
Filed: 1990-01-30
Abstract: Motor drive coils 2a, 2b, 2c Fig. 1, (101a, 101b, 101c Fig. 3; 201a, 201b, 201c Fig. 7) are connected to drive transistors 1a, 1b, 1c (108a, 108b, 108c; 203a, 203b, 203c) and voltages induced in the drive coils when the motor is rotating are detected to produce energization switching signals (OUTU, OUTV, OUTW Fig. 2; VOUTU, VOUTV, VOUTW Figs. 4-6; VOUTA, VOUTB, VOUTC Figs. 8 and 9) so that the motor can be continuously driven at optimum energization timing regardless of its rotational speed. When a command signal is applied to a switching circuit (104 Fig. 3) to instruct the motor to rotate in the backward rotational direction while the motor is rotating in the forward rotational direction, torque of the opposite direction is produced to change the rotational direction of the motor. Further, separate-excitation timing pulse signals (PA, PB, PC) are used to sequentially switch over energization of the motor drive coils when the motor is not rotating or it is rotating at a very low speed, and hence voltages induced in the motor drive coils cannot be detected. As soon as the voltages induced in the drive coils have become able to be detected due to the rotation of the motor, self-excitation timing pulse signals (PU, PV, PW) are then used to sequentially switch over energization of the drive coils. …<IMAGE>…

Title: Turbine assembly
Inventor: MEANWELL JOHN ERIC
IPC: F03B17/06
Filed: 1990-05-16
Abstract: in a bladed rotor 10 for a wind or water turbine or a fan or propeller blades 12 extend generally parallel to, and are rotatable about, an axis 14, the angle of incidence of each blade 12 being controlled to vary with respect to the angular position of the blade about the axis 14. Each blade 12 has a pivotal mounting 16 adjacent its leading edge 18 and at a predetermined distance from the axis 14. A respective linkage 22 extends from a pivotal attachment 24, adjacent the trailing edge 20 of each blade 12, to a hub 26 offset from the axis 14. Rotation of the blades about the axis 14 generates a resultant fluid flow in a direction W determined by direction of offset of the hub 26 and of a magnitude determined by the separation of the axes of the hub 26 and turbine axes 14. Control mechanisms for positioning of the hub 26 are disclosed. Such a bladed rotor 10 when driven by fluid flow can have application in a wind or water powered turbine generator and, when driven mechanically, as a fan or marine propulsion unit. <IMAGE>
