IPC: A47G25/48
Filed: 1994-02-04
Abstract: PCT No. PCT/GB94/00206 Sec. 371 Date Nov. 1, 1995 Sec. 102(e) Date Nov. 1, 1995 PCT Filed Feb. 4, 1994 PCT Pub. No. WO94/17706 PCT Pub. Date Aug. 18, 1994There is disclosed a clip for a garment hanger on which clothes are hung directly, and which has front and rear gripping plates which are movable one relative to the other. A locking mechanism, preferably in the form of an arm in a fixed one of the two plates interlocks the movable plates for gripping a garment within the clip. A movable pressure device preferably mounted on the movable one of the plates is used to effect release of the locking means and immediately the locking means is released, the pressure device acts directly on the movable plate to force it away from the other plate to thereby quickly and easily release a garment previously held within the clip. In an alternative, a flange extends from the movable plate and has locking tooth thereon engageable with teeth on the release arm. The flange extends across the teeth in use to prevent delicate garments becoming entangled in the locking mechanism between the movable plates. Such constructions are particularly useful with soft clear plastics materials such as K-resin co-polymers.

Filed: 1995-08-03
Abstract: An engine shutdown valve comprises a housing and a gate movable within a housing between a first position where the air flow through the shutdown valve is substantially unrestricted to a second position where the opening is restricted thereby stopping air flow.  The gate is pivotable about an axis. The gate has an extension with a recess which is engageable by a piston movable between a first position where the gate is held in its latched position and a second position out of engagement with the recess so as to allow the gate to move to a position where the air passageway is closed. The gate is movable by a rod attached to the gate lever and which rod is biased by a compression spring mounted within a sleeve.  The spring is adjustable to increase or decrease the force on the gate and such adjustment can be accomplished from outside the shutdown without disassembly of the entire valve.

Title: Delay detection circuit and low-noise oscillation circuit using the same
Inventor: YAMASHITA KAZUO
IPC: H03L7/113
Filed: 1995-09-21
Abstract: A delay detection circuit and a low-noise oscillation circuit using such a delay detection circuit.  When the oscil-lation output of a VCO is to be supplied to two high frequency mixers, a .pi./2 phase shifter 24 in the front stage of one of the high frequency mixers gives a quadrature form.  High fre-quency components are removed from the output voltage of the high frequency mixers by LPF.  DC components are also removed from the output voltage of the high frequency mixers by HPF.          The output voltages of low frequency mixers contain secondary phase noise components proportional to squared phase noise components and primary phase noise components proportional to the phase noise components and also depending on the delay time ? of a delay unit.  When the output voltage of one of the low frequency mixers is subtracted from the output voltage of the other low frequency mixer, the secondary phase noise components are offset and the dependence on the delay time ? is removed from the primary phase noise components.  The resulting voltage is used as a control voltage for the VCO (10).  No voltage control delay unit or feedback loop for controlling it are required.

Title: Design of an electronic beam forming network for phased array applications
Inventor: BELISLE CLAUDE
IPC: H01Q23/00
Filed: 1995-11-24
Abstract: Optical control of array antennas in a radar and communication application is described. The opto-electronic architecture simplifies the antenna element interface unit (AEIU) by executing the phase control function in a central processor unit, thus lowering the fabrication cost, and providing greater stability of the phase control. This architecture further eliminates the need for a distribution network for the phase control information. Dynamic amplitude control is performed in a specific number of locations.  Signal distribution is done through a fiber-optic network allowing a more flexible and lighter distribution network with lower propagation loss and immunity to electromagnetic interference.
