Abstract: Capillary collection devices are known in which liquid is introduced into the device using capillary transport. However, such devices have a limited volume in which liquid can be collected due to the capillary effect. Described herein is a device (10) constructed to collect a liquid by drawing the liquid to an intermediate point (44) by capillary attraction only, and then from that intermediate point (44) further into the device (10) by gravity. The device (10) comprises a first portion (12) and a second portion (40) connected at an angle (α) to one another at the intermediate point (44). The first portion (12) has an inlet aperture (14) which allows liquid to enter the device (10) by capillary attraction. The inlet aperture (14) comprises oppositely disposed surfaces (18, 20) spaced apart a distance (d₁) no greater than that which will maintain capillary flow into that portion (12) through the aperture (14). The second portion (40) allows gravity flow further into the device (10) from the intermediate point (44) and comprises opposed surfaces spaced apart a distance (d₂) effective to allow gravity to passively overcome any surface attraction caused by the opposed surfaces, the inclination of the second portion (40) to the first portion (12) allowing liquid to drop below the horizontal plane extending from the intermediate point (44).

Title: Long-chain ketene dimers
Inventor: BROLUND NILS
IPC: D21H17/17
Filed: 1992-12-21
Abstract: Long-chain ketene dimers are prepared in a process in which in the absence of an organic solvent carboxylic acid chloride is fed, with intensive mixing, into a recipient of triethyl amine at a rate of not more than 3 moles/hour per mole of present triethyl amine, and mixing, feeding, and heat exchange are so attuned to each other that the viscosity of the mixture always is less than 250 mPa.s, measured at 60°C (rate of shear higher than 100 l/sec), and the molar ratio of the total amount of carboxylic acid chloride fed in to the recipient amount of amine is 1 : 1,025 to 1 : 2, and after the conversion the reaction mixture is treated with diluted aqueous hydrochloric acid or an aqueous solution of triethyl amine hydrochloride and hydrochloric acid, and the ketene dimer is separated. The ketenes are highly suitable for use in paper sizing.

Abstract: Conventionally co-axial cable is made in a continuous extrusion machine by continuously extruding an aluminium tubular cladding (1) through an annular die and simultaneously continuously introducing a core (4), comprised of a conductive wire surrounded by insulation, through a bore in a mandrel (3). A gap is inevitably present between the outer surface of the core (4) and the tubular cladding (1). To eliminate the gap it is necessary to reduce the diameter of the tubular cladding by swagging or drawing. The present invention disposes of the swaqging or drawing step by compacting the insulation of the core before introduction to the mandrel (3). The insulation then gradually expands to recover its original diameter and fill the cladding which has been extruded to its final diameter.

Abstract: An X-ray apparatus (10) has a motor for moving its components in different directions. A collision sensor (12) is formed by a bladder (30) attached to a component of the apparatus and deformation of the bladder produces a change in the pressure of air within the bladder (30). The bladder has an air vent (46) to the atmosphere which can be sealed by operation of a valve (44). A pressure sensor (40) produces two control signals when the pressure within the bladder (30) exceeds first and second threshold levels respectively. The second threshold level is greater in magnitude than said first threshold level. The first control signal closes the valve (44) and causes a motor control circuit (66) to discontinue any application of electricity to the motor. The second control signal opens a switch (64) through which electricity normally flows to the motor. A mechanism also is provided to simulate a collision by compressing the bladder (30) to test the operation of the detection system.

Abstract: This describes a test algorithm allowing detection of specific faults in multiport memories, that is to say memories which can be addressed independently through several ports. This algorithm uses operations for simultaneous writing by several ports of the memory and allows detection of complex coupling faults in which the state of a memory cell cj is disturbed by a simultaneous state transition of two neighbouring cells ci and ck. The algorithm includes, for a two-port memory, two groups of four test sequences (S1, S2, S3, S4; S'1, S'2, S'3, S'4). Each sequence includes a group of several read operations (R00, R11) and write operations (D00, D11, D10, D01) carried out on pairs of cells. The pairs of cells processed in each sequence follow one another in a specified order; the reverse order is used for some of the sequences. <IMAGE>
