Patent GB-2024974-A (GB)
Title: Tube connectors
IPC: F16L47/16
Filed: 1979-06-29
Abstract: A connector for medico-surgical tubing 8 has a plastics body 1 with a male Luer tapered forward portion 5 that is shaped for engagement with a coupling member 18 having a co- operating Luer tapered bore 20. The body 1 has a rear portion 4 of prismatic shape and square cross- section that is embraced by a square aperture 13 in a rear flange 12 of a locking ring 2. The locking ring 2 has a cylindrical portion 11 which extends axially of the connector and which has an internal screw thread 15 and 16 for engaging co-operating projections 21 and 22 on the coupling member 18. The locking ring 2 is thereby free to slide axially along the prismatic portion 4 of the connector body 1 but is prevented from rotation relative to it. <IMAGE>

Patent GB-2030344-A (GB)
Title: Phonograph Tone Arm
IPC: G11B3/36
Filed: 1979-08-16
Abstract: A phonograph tone-arm assembly for use with a record turntable includes a coupling member 32 extending from a movable pick-up cartridge support arm 20. The member 32 rigidly couples the arm with a record 18 by way of the record grooves as the record rotates on the turntable. The coupling member imparts movement to the support arm which tracks radially over the record surface along a guide bar 24, and also isolates the cartridge stylus 26 from inertial effects of the arm when the coupling member contacts the record grooves, which is of advantage with warped records. The effective length of the rod 32 is adjustable and the rod is locked by a nut 40. A pad 34 of low- friction material is provided on the lower rod end. <IMAGE>

Title: Circuit arrangements for converting A.C. voltages into higher A.C. voltages
IPC: H05B41/04
Filed: 1979-08-16
Abstract: In order to convert an alternating- current voltage into a substantially higher alternating voltage a load (9) e.g. a gas discharge lamp is connected to alternating current power supply input terminals (3) via the series combination of a choke (inductor) (4) and a capacitor (5) forming a resonant circuit. A starting device (8) including a full-wave rectifier (10), to which a voltage divider constituted by resistors (12, 13) is connected, is connected in parallel with the load (9). A further capacitor (14) is connected in parallel with one resistor (13) of the voltage divider and is connected by way of a connecting diode (15) to the control electrode of a controllable switching element (1), which is also connected to the output of the full-wave rectifier (10). The thyristor may be replaced by a transistor, or a triac in which case the rectifier could be located after the triac. In operation, when the thyristor 1 is fired, capacitor 5 charges and its voltage is added to the supply voltage to provide a high ignition pulse for the discharge lamp. A fusing element 2 protects the circuit against overload. <IMAGE>

Title: A method of determining the content of a gaseous and/or vapour component in a gas and/or vapour mixture.
IPC: G01N33/52
Filed: 1979-09-17
Abstract: Portions of a reagent capable of reacting with the gaseous and/or vapour component are successively exposed to the gas and/or vapour mixture. Each portion of the reagent is exposed until it has reacted with the gaseous and/or vapour component to change colour by a predetermined amount, after which the next portion of reagent is thus exposed. The content of the gas/or vapour component is then determined from the number of portions of reagent exposed during a predetermined time. The invention also provide an elongate strip of reagent paper suitable for carrying out the method, which is marked in units of length.

Title: Process for Using Residual Sludges from Industrial Painting with Oven-curable Paint in Spray Booths
IPC: B27N3/00
Filed: 1980-04-03
Abstract: The water content of paint sludge obtained from painting with oven- curing paint is reduced to a residual value not exceeding 35% by weight by mechanical working such as compressing, extruding or rolling. The obtained moist plastic sludge and a fibrous reinforcing material are combined by for example kneading or sandwiching to form a heat-curable panel without the addition of extra heat-curable resin. The sludge and fibrous material are hot-pressed at an elevated temperature and for a time sufficient to at least partially heat-set the panel.
Patent GB-2061813-A (GB)
Title: Screw press
IPC: B30B1/18
Filed: 1980-10-13
Abstract: A screw press has a flywheel (1) rotatable continuously in one direction and coupled to the screw (3) by a friction coupling which, on the attainment of a predetermined pressing force, releases under the action of a control part responding to deceleration of the screw, the n control part being in the form of a support device (15) inserted into 7 the force transmission path of the coupling between the flywheel (1) and screw (3). 
<??>Conveniently the torque transmittable between the flywheel (1), or an axially displaceable piston (9) held fixed against rotation therein, and the support device (15) is less than the torque transmittable between the support device (15) and the screw (3). 
<??>Deceleration of the screw (3) results in deceleration of a coupling disc (4) and a ring (16). Rotation of the latter relative to the flywheel (1) and the piston (9) causes the ring (16) to move away from the friction lining (6) on the disc (4) and interrupts the transmission of force to the screw. 
<??>Various forms of support device are proposed for example rectangular or triangular screw threads, pendulum links, cooperating wedges or two-part ball or cylinder devices.

Title: Second eyes
IPC: G02C7/00
Filed: 1981-02-09
Abstract: While doing some tapestry work with new glasses fresh from the opticians I began to think, what a help it would be to women if we could have glasses which magnified larger than normal sight so that we could see such things as the holes in the canvas bigger. This would avoid much eye strain and make for better work. Maybe the lenses made out of plastic magnifying sheets for cheapness or glass for more expensive ones.

Title: Projectile guidance system
Inventor: OSWALD JOHN MATTHEW
IPC: F41G7/30
Filed: 1983-05-17
Abstract: In a guidance system for an 'unpowered' spin-stabilised projectile such as a shell 11 equipped with a lateral thruster 17 and fired from a gun on a leading target-intercepting trajectory, the target, and in its later stages the shell, are tracked by microwave radar 12 and if necessary a new trajectory computed. The characteristics of the lateral thruster 17 are taken into account to determine the optimum trajectory point to fire the thruster. The spin orientation of the projectile is determined by including as part of the shell a radar reflector 19 or microwave transmitter (not shown) which returns or sends a signal modulated with spin orientation and including at the launch station a receiver 20 and decoder 22 of the signal. A deviation from the optimum trajectory point is calculated at which the lateral thruster is in the correct orientation and a command signal generated at 24 to initiate lateral thrust. <IMAGE>
