Title: A method of measuring the amount of substance associated with a material in the presence of a contaminant
IPC: G01N21/35
Filed: 1979-01-09
Abstract: The quantity of a substance in a specimen is determined in the presence of a contaminant by using a first beam of radiation within an absorption band of the contaminant and a second beam of radiation within both an absorption band of the contaminant and an absorption band of the substance, the respective intensifies of the beams after incidence upon the specimen being detected and converted into electrical signals, functions of which are subtracted to indicate directly the quantity of the substance in the specimen.

Title: Self-drilling self tapping screw
IPC: F16B25/00
Filed: 1979-08-11

Title: Baby's Panty-napkin or Pilch
IPC: A61F13/15
Filed: 1979-10-12
Abstract: A baby's pilch comprises a flexible impermeable sheet 1 inside which an absorbent pad 9 and two elastic members 12 are fixed. The absorbent pad 9 comprises a first layer 10 in contact with the impermeable sheet 1 and a second layer 11 which is of smaller width than the first layer and is fixed over the top of the first layer. Owing to the pull of the elastic members 12 and the greater stiffness of the middle portion of the absorbent padding 9 where there is the second layer 11, the pilch, when in use, adopts an inwardly concave transverse profile in the crotch area of the pilch. This improves the fit of the pilch to the baby's bottom, crotch and thighs. <IMAGE>

Title: A deflecting objective for corpuscular radiation apparatus
IPC: H01J37/147
Filed: 1980-01-11
Abstract: A deflecting objective for corpuscular radiation apparatus comprises a deflecting system 10 disposed in the magnetic field of electromagnetic image forming lens including coil 4. Coil 4 is toroidally enclosed by an iron jacket consisting of outer cylinder 6, inner cylinder 8, end plate 5 and cover disc 11, a gap 12 being disposed in the radial direction between the outer cylinder 6 and the cover disc 11. Advantageously the axial length of the outer cylinder 6 is greater than the axial length of the deflecting system, and the outer cylinder 6 is closed above the deflecting system by an iron plate 13 formed with a bore 7 screening against external magnetic fields being provided.

The ratio of the bore diameter in the 3 stage deflection arrangement of Figure 3 (not shown) may be selected to counter deflection chromatic aberration, coma, and astigmatism. Reference is made to the semivalue width of the magnetic field along the axis being of the order of the focal length magnitude, and to a target mechanically displaceable perpendicular to the axis. Electron lithographic applications are exemplified. <IMAGE>

Title: Random selection of numbers
IPC: G07C15/00
Filed: 1981-06-08
Abstract: A method of electronically obtaining a random selection of numbers comprises presenting each unselected number for selection for an equal time period by incrementing a counter, searching a memory store for a representation of the counter number and when no such representation is found, placing the counter number in a latch for a set time period, but when a representation of the counter number is found in the memory store, further incrementing the counter and researching the memory store until a previously unselected number is available for placement in the latch at the beginning of the next consecutive set time period. This cycle is repeated until the operator makes a request for a selection when the number at that time in the latch is displayed by an output latch and a representation of this randomly selected number is added to those already in the memory store. <IMAGE>

Title: Cartridge for use with bolt anchors
IPC: F16B13/14
Filed: 1981-07-03
Abstract: Cartridges for bolt anchors comprise a frangible casing 1 containing a liquid-settable solid component 3 and in a separate compartment a reactive liquid component 4. The solid component 3 occupies a volume which is less than the normal free volume of the casing, preferably by being pelletised or encased by a liquid-permeable or liquid- degradable material 11 which serves to restrict the cross-sectional area occupied by the solid component in the casing. When required for use, the liquid component 4 is caused to be released from its compartment and to come into contact with the solid component 3, such as by breaking the weak heat seal 2. The free space 5 around the solid component 3 allows the liquid component 4 to come into contact with the solid component 3. This can be enhanced by providing a partial vacuum in the space 5. Organic or inorganic self setting systems may be used. <IMAGE>

Title: Control of i.c. engine turbocharging
IPC: F02D41/00
Filed: 1981-09-04
Abstract: A detector (65) detects the speed of rotation of the turbocharger 62, a detector (44) detects whether or not the engine is knocking, and a control circuit (100) incorporating a microcomputer calculates the degress of opening of intake and exhaust by-pass valves (92 and 68) in accordance with a stored program and provides the digital signals for driving by-pass valve actuators (90 and 70). The turbocharger is driven during medium end high-speed operation, as well as acceleration, to thereby increase the engine output, whilst the turbocharger is prevented from constituting a resistance against the intake air flow in the low-speed operation of the engine in which there is no substantial supercharging effect and from over- speeding. An air flow rate sensor (24) and a throttle valve position sensor (148) provide inputs to the control circuit (100) thereby to adjust the turbocharger for acceleration and decaleration. <IMAGE>
