Title: Cartridge counter
Inventor: THOMAS STEVEN JOHN
IPC: G06M1/28
Filed: 1986-03-17
Abstract: A cartridge counter is provided for a firearm and is actuated each time a cartridge leaves a magazine P. A particular pair of terminals M1 or M2, depending on the magazine used is bridged when a cartridge is inserted, driving the counter to display at B a predetermined count, being the number of cartridges in a full magazine. Each time the bolt S of the firearm retracts (whether pulled back for priming or upon recoiling) it displaces a spring-based pin F to depress an actuator button C of the counter to decrement the displayed count. A battery A is provided for the counter. <IMAGE>

Title: Indicating wear in bearings
Inventor: POPLE JOHN RAVENHILL
IPC: G01B7/06
Filed: 1986-07-25
Abstract: A bearing for a moving member such as a propellor shaft of a ship comprises a bearing material (21) having a free surface (3), Fig. 4, for supporting the member as it moves and a wear detector (6). The wear detector is positioned at a predetermined depth below the free surface (3) and comprises a means of indicating when the bearing material has eroded down to said depth as a consequence of the movement of said member. The wear detector (6) may include a pair of conductors and a means of monitoring the electrical resistance across the conductors so as to detect a change in the resistance when the bearing material has eroded to that depth. Alternatively, the wear detector (6) may include a means (41) Fig. 7 for generating a beam of radiation and a means (42) of monitoring the beam, the beam being interrupted once the bearing material has eroded to said depth. <IMAGE>
Patent GB-2194054-A (GB)
Title: Magnetometer
Inventor: DYTE NICHOLAS
IPC: G01H9/00
Filed: 1986-08-15
Abstract: A magnetometer operates by measuring the change in Youngs Modulus of an amorphous metal sensor part (1) when a magnetic field (9) is present. This measurement is made by forming an oscillator (4) from the amorphous metal (6) (7) (8) and measuring the changes in its oscillation when a magnetic field is present. The oscillator may be caused to vibrate by a light beam from pulsed laser diode (10) of a photoacoustic drive measures (2). The vibrations of the amorphous metal are detected by detecting at (12) a reflected light beam from laser diode (13) which is modulated by the vibrating amorphous metal. Alternatively Youngs modulus may be determined by measuring the speed of sound through the metal on applying a static stress and sensing deformation. <IMAGE>

Title: Apparatus for automatically weighing extruded thermoplastics sections, and adjusting the extrusion apparatus
Inventor: MILANI FRANCESCO
IPC: B29C48/92
Filed: 1986-09-08
Abstract: The extruded section (11) which is continuously delivered by a pulling unit from the extruder (12), onto a table (15), is cut into lengths by a shear (13) and each length is sequentially lowered with the table (15), to be deposited on weighing trays (40) which pass through table openings (39). An electronic control (47) automatically adjusts the production speed of the section, e.g. of the pulling unit, extruder (12), or metering unit, to maintain the section weight within predetermined limits. Sections within or outside the limits are respectively unloaded onto opposite sides of the table, either by tilting the table about alternative pivots (26) on opposite sides of the table (15), or by employing means (65, Figs. 5 & 6) which displaces the sections (11) laterally from the table and weighing means (10), onto trays (59) which are then further conveyed by overhead pincers to a car (75). <IMAGE>

Patent GB-2181864-A (GB)
Title: Improvements in heating systems using a fuel-burning source
Inventor: MACHARG JAMES ADRIAN
IPC: G05D23/275
Filed: 1986-10-10
Abstract: The rate of dissipation of heat from a heating load is represented by the voltage on capacitors C3a-e. They are charged from a capacitor C4 through a transistor TR1 at the instant that a thermostat (not shown) switches off and so de-energizes transformer X1, which supplies power to the control system. They discharge via a constant current device IC5 and resistor R4. A voltage follower IC6 and load resistor R5 provide a control voltage to charge a capacitor C14, the control voltage being proportional to the time in which the load thermostat is "off". The control voltage which appears on re-energization of the system triggers a Schmidt trigger IC7 after a delay determined by when the capacitor C14 becomes charged to the triggering voltage. Boiler relay L3 is thus energized with a delay inversely proportional to the control voltage. <IMAGE>

Title: Piezoelectric composites
Inventor: GOOSEY MARTIN TREVOR
IPC: H01L41/37
Filed: 1988-05-26
Abstract: The invention relates to piezoelectric composites and more particularly, but not exclusively, to a method of manufacturing a composite material in which a piezoelectric ceramic is dispersed as a powder within a polymer matrix. The method comprises forming a composite including a ceramic dispersed within a polymer matrix, partially curing the polymer matrix to a desired resistivity relative to the resistivity of the ceramic, applying a poling field to the composite to render the ceramic piezoelectric and increasing the resistivity of the polymer matrix by further curing. In one embodiment electrodes are bonded to the ceramic polymer composite by utilising the residual reactivity in the partially cured composite material to bond chemically the composite to the electrode material.

Patent GB-2210685-A (GB)
Title: Sensor
Inventor: WILLIAMS DAVID EDWARD
IPC: G01N21/35
Filed: 1988-10-03
Abstract: A sensor includes an optical fibre, having a core and a cladding, said optical fibre having a portion so shaped that light can leak from the core in the vicinity of the portion such that the electrical field associated with the light can interact with an environment in communication with the fibre. Means are provided for detecting a change in the intensity of light in the fibre. The portion may be shaped by providing a bend in the fibre. The sensor may be used to detect a species in the environment which gives rise to a change in the intensity of light in the fibre (e.g. methane). The intensity of the detected light may decrease or increase in response to the interaction with the environment. The electrical field may be used to excite fluorescence from an indicator species in the presence of the species to be detected, the fluorescence being detected using the same or a different fibre. Refractive index changes may be used to detect a species, as may backscattered light. The fibre may run through a plurality of sensing positions in a system using optical time domain reflectometry.
Patent GB-2226434-A (GB)
Title: Monitoring system for vehicle tyres
Inventor: COCHEME MANUEL ALFRED XAVIER
IPC: B60C23/06
Filed: 1988-12-23
Abstract: The system comprises sensor means 10 for producing an output signal representative of the rotational speed of each vehicle wheel when the vehicle is travelling, comparator means 18 for comparing at least two of the output signals (or signals derived therefrom) and producing a different signal when one sensed rotational speed differs from another, and indicator means 22 for indicating that the difference signal is being produced. The system relies on the fact that, in the case of a four wheeled vehicle for example, if all the tyres are in good condition and are correctly inflated, all four wheels should rotate at equal speeds when the vehicle is travelling in a straight path. If any tyre is not fully inflated, for instance due to a puncture or due to undue wear of the tyre tread, a difference signal is generated in the system and the fault indicated. The sensor means may be an electromagnetic or electro-optical sensor, the output pulses of which may be integrated or counted over a given period of time or a given distance of travel prior to comparison. <IMAGE>

Title: Anthropomorphic dummies
Inventor: WEEKS RICHARD JOHN
IPC: G09B23/32
Filed: 1989-11-13
Abstract: A spinal column for an anthropomorphic dummy is composed of a flexible rod 1 onto which are mounted several loose-fitting co-axial spools 2a-2j separated by thin rubber washers 3. Spools 2b-2g may carry ribs. The upper end of the flexible rod is attachable to a shoulder member 5 and the lower end can move vertically within a cylindrical housing 4 which is located in the pelvic region. Rubber washers 3, 3a and compressible washer 13 determine the at-rest position of rod 1 relative to housing 4. Because of the compressibility of these washers, the spine is compressible and extendable to an extent, the pelvis being able to move upwards and downwards with respect to the shoulders and ribs. The spinal column enables simulation of the tendency of human subjects to slump on ejection seat firing. <IMAGE>
