Title: Making armatures for electrodynamic machines
Inventor: BRADTMUELLER LYNN ED
IPC: H02K15/04
Filed: 1993-01-29
Abstract: An operator sequentially inserts magazines containing a required number of hairpin conductors HC for an armature to be made, an armature core comprising a plurality of substantially aligned laminations preassembled to form the core and a commutator, and removes armatures completed by assembling these components. The use of a hairpin magazine M, including the hairpin conductors required for an armature, permits simultaneous transfer of all the hairpin conductors into upper twist tooling 110 wherein upper ends of the hairpin conductors adjacent end turn portions of the conductors are moved apart relative to one another. The frog leg conductors thus formed are removed from the upper twist tooling 110 and inserted into slots of an armature core which has been earlier inserted into the system. The frog leg conductors are fully pressed through the armature core into lower twist tooling 124 which then is operated to move the ends of the conductors extending beyond the armature core away from one another and into alignment with other conductors for insertion into a commutator for the armature, which commutator was earlier placed into the system. The commutator is properly positioned by tooling 130 beneath the armature core which is then pressed onto the commutator. The operator removes the completed armature and replaces it with a commutator for the next armature. <IMAGE>

Title: Formation of densified material
Inventor: RAMM ERIC
IPC: G21F9/30
Filed: 1993-04-14
Abstract: Dense ceramic material in the form of a block is made in a hot uniaxial press, particulate precursor material for the ceramic being supplied in cylindrical metal capsules (10) having a convoluted or bellows-side wall (21). The apparatus is operated to form a stream of preferably alternating axially elongated cylindrical spacers (11) and lesser diameter bellows capsules (10). Each spacer (11) has a recessed end face (24) for accommodating a corresponding end portion (26) of a bellows capsule so that the bellows capsule is centered and there is restraint against radially outward expansion of the capsule under the heat and pressure which is applied. The apparatus is operated essentially continuously and the stream moves progressively upwardly so that discharge of processed containers and spacers occurs at the upper end and capsules to be processed and spacers are inserted intermittently at the lower end. <IMAGE>

Title: Inductive communications system
Inventor: BROWN MICHAEL GEORGE CONRAD
IPC: H04B5/00
Filed: 1993-06-02
Abstract: The system comprises a twisted pair of leads 20 including a number of first coils 22 coupled to a master station 10. Communication between a microphone/ loudspeaker in the master station and various locations proximate the lines is effected using pick-up devices 24 each including a communications amplifier coupled via a tone controlled switch to a further coil. The tone controlled switches toggle their associated amplifiers ON and OFF in response to pro-set frequency pulses induced in their associated further coils in response to the application of a pulse signal applied to the leads from a tone generator (switchable between different frequencies) in the master station. The pick-up devices 32 may comprise a further pair of leads 42 including first coils 40 driven by an amplifier enabled by a tone controlled switch in the manner described. The tone generator in the master station may be arranged to provide a signal which acts to hold a tone controlled switch and its associated amplifier ON - which signal is used as the carrier signal for the voice communication. <IMAGE>
Patent GB-2279131-A (GB)
Title: Choke valve
Inventor: TAYLOR BRIAN B
IPC: F16K47/04
Filed: 1993-06-16
Abstract: A pressure-balanced stem choke valve comprises a casing (5, 10) providing inlet ports (10A) and a fluid discharge (15), fluid flow between the ports being regulated by a flow control element (7) moveable by means of a stem. The element (7) moves relative to a pressure balance chamber (18) and includes an inner fluid chamber (14) controlled fluid flow being possible between the inlet ports (10A) and the fluid chamber (14) via ports (13). Conduit means (19, 20) between the chambers (14, 18) ensure pressure balance conditions. The choke valve eliminates sand sedimentation therein by eliminating any stagnant flow area at or within the flow control element. This is achieved by recirculation flow between the chambers (14, 18), the conduit means including outward (20) and return (19) passages to this end, whilst fluid entering the element fluid chamber (14) is biassed to flow towards the outward fluid passage (20). Further, strategically positioned in-line twin porting (13L, 13R) is provided in the element (7) to encourage a continuous flow loop around the pressure balance chamber (18) for the avoidance of solid sedimentation. <IMAGE>

Title: Electrostatic discharge protection circuit
Inventor: METZ LARRY S
IPC: H01L27/04
Filed: 1994-11-08
Abstract: An ESD protection circuit that uses the well-known SCR latch up effect present in CMOS processes to divert the ESD current pulse away from sensitive circuit structures. The circuit uses an inverter trigger device (40, 42), with a voltage divider (44, 46) on its output, to control the amount of voltage necessary to cause latchup. This feature enables the SCR (10) absorb a high current pulse on the CMOS pad structures (15) caused by an ESD event, while also preventing the circuit from latching when an ordinary CMOS voltage is applied to the pad while the circuit being protected is unpowered. The circuit insures that the SCR will latch independent of breakdown effects, while also allowing the threshold voltage at which latchup occurs to be adjusted into the circuit by varying the sizes of the two FETS (44, 46), used as the voltage divider, at the fabrication stage. <IMAGE>

Title: Measuring erythrocyte sedimentation rates
Inventor: KOZULIC BRANKO
IPC: G01N15/05
Filed: 1995-05-12
Abstract: A device for measurement of sedimentation rate of erythrocytes in a sample of blood is in the form of a tube containing a filter plug of material able to absorb aerosol droplets. The blood sample enters the tube from one end and fills the tube until it comes in contact with said plug, so that the interface between the plug and blood represents zero point for the measurement of the sedimentation rate. The plug prevents the exit of the aerosol through the upper opening of the tube and once the blood sample reaches the plug, the, flow stops precisely at the desired height. Contamination of operating technician by aerosol possibly containing infectious agents from the blood sample is therefore avoided.
