Patent EP-0348802-A3 (EP)
Title: Controller for electric clamp
IPC: B25B5/12
Filed: 1989-06-20
Abstract: A controller (21) for an electric clamp (1) closes the 
clamp rapidly at first, then runs at a slower speed while 
contacting the workpiece, and speeds up again after contacting 
it, to close with full clamping force. Arrival of the clamp at 
the position for slowing down is directly detected by means of 
a proximity sensor (41), as are arrivals at other positions 
(39,43). The speed of operation is relatively insensitive to 
the voltage of its AC electrical power source because an 
open-loop compensating signal (111,113,715) controls the pulse 
duration of rectified DC pulses that drive the motor. The 
controller has dynamic braking (101,105) that is applied 
between individual pulses of pulse trains of motor current; 
this results in significant increase in swings of current 
values for a given motor speed, that reduces harmful effects of 
mechanical friction. Two jogging speeds are selectable (167).

IPC: B62B5/06
Filed: 1989-01-05
Abstract: An adaptor handle for use on wheeled vehicles having 
two spaced-apart handles (50) for application of propulsion 
forces and steering is disclosed characterized by use of 
an elongate arm (12) extensible between the spaced-apart 
handles of the wheeled vehicle which includes clamp means 
adjacent each end thereof to enable the adaptor handle to 
be rapidly coupled onto the spaced-apart handles and a

of the arm. The clamp means are formed as over-center 
latches having plural contact shoes and shoe spacers which 
allow the adaptor handle to be used on wheeled vehicles 
having differing sized handle grips. Additionally, one or 
more auxiliary hooks (60) are provided to enable storage of 
desired items upon the adaptor handle during use.

Title: Process for preparing aluminium nitride and aluminium nitride so produced
IPC: C30B11/00
Filed: 1989-11-29
Abstract: A process for preparing aluminum nitride comprises 
reacting molten aluminum with nitrogen (or a nitrogen 
precursor) at a pressure of up to about 0.2 MPa (absolute) in 
the presence of less than about 5% by weight of a dopant 
selected from the metals magnesium, calcium, strontium and 
barium. The dopants reduce the passivation of aluminum to the 
formation of the nitride and impart desirable properties to 
the resulting aluminum nitride. In the case of magnesium, the 
nitride can be obtained in the form of novel single crystals 
of 1-10µm in size. In the case of the other dopants, the 
resulting aluminum nitride can be sintered without the use of 
additional sintering aids.

Title: Hydraulic transmission coupling apparatus
IPC: F16D31/06
Filed: 1990-03-20
Abstract: A hydraulic transmission coupling apparatus which is 
used instead of a center differnetial or a viscous 
coupling being usually mounted between a front wheel drive 
shaft (1) and a rear wheel drive shaft (2) of a four-wheel 
drive vehicle, and transmits driving force existing 
between the two shafts. The hydraulic transmission coupling 
apparatus is provided with a vane-type hydraulic pump (3) 
which generates hydraulic pressure corresponding to a 
relative rotation speed difference of the two drive shafts 
(1,2) and a variable throttle valve (5) being disposed in 
the passage (48) connecting a discharge port of the 
hydraulic pump (3) with a tank (T), whose opening area 
varies according to the hydraulic pressure generated by 
the hydraulic pump (3), thereby driving force to be 
transmitted being increased or decreased steeply as the 
rotation speed difference becomes larger.
Patent EP-0398180-A3 (EP)
Title: Method of and arrangement for distinguishing between voiced and unvoiced speech elements
IPC: G10L25/93
Filed: 1990-05-11
Abstract: The spectra of voiced sounds lie predominantly at or below about 1 kHz. The spectra of unvoiced sounds lie predominantly at or above about 2 kHz. It is known to determine the lower- and higher-frequency energy components contained in a sound or sound element, to compare these energy components, and to use the result of the comparison to make a voiced-unvoiced decision. Since the distributions relative to voiced and unvoiced segments are overlapped, false decisions are liable to occur. The invention is predicated on the fact that a change from a voiced sound to an unvoiced sound or vice versa always produces a clear shift of the spectrum, and that without such a change, there is no such clear shift. From the lower-and higher-frequency energy components, a measure of the location of the spectral centroid is derived which is used for a first decision. Based on the difference between two successive measures, a second decision is made by which the first can be corrected.

Title: Circuit arrangement
Inventor: BERGERVOET JOZEF REINERUS M
IPC: H05B41/24
Filed: 1992-01-30
Abstract: The invention relates to a circuit arrangement suitable for operating a low-pressure mercury discharge lamp by means of a high-frequency current, comprising   circuitry (I) for generating the high-frequency current from a supply voltage, and a modulator (II) for the substantially square-wave modulation of the amplitude of the high-frequency current with a modulation frequency f.   According to the invention, the circuit arrangement is further provided with circuitry (V) for limiting an amplitude of a re-ignition voltage across the low-pressure mercury discharge lamp to a voltage Vi. It is achieved by this that the interference with infrared systems caused by a lamp operated on the circuit arrangement is substantially fully suppressed. <IMAGE>
Patent EP-0536882-A3 (EP)
IPC: A61B/
Filed: 1992-08-21
Abstract: A surgical stapling instrument (50) for performing a circular anastomosis stapling operation is provided. The surgical instrument includes a stapling head assembly (60) mounted by a curved shaft (70) to an actuator handle assembly (80) and incorporates an improved actuator mechanism for transmitting the required operating forces and movements from the actuator handle assembly through the curved shaft to an anvil (100) and staple driver (62) of the stapling head assembly. The stapling head assembly includes a longitudinally movable trocar (73) detachably secured by one or more retainer clips (110) on a hollow shaft of the anvil. When the trocar is retracted, the anvil shaft slides into a central support tube (66) which aligns the anvil axially and circumferentially with a staple holder on the stapling head assembly. The retainer clips are locked against the trocar by the support tube and transmit tension from the trocar to the anvil with no tension load on the anvil shaft. The actuator mechanism permits adjustment of the anvil gap to produce a desired staple height and precludes actuation of the staple head assembly if the anvil gap is set outside of a predetermined range. Also, the actuator mechanism is adapted to both advance and retract the staple driver relative to the staple holder in the stapling head assembly. Further, an improved arrangement for attaching the support shaft to the stapling head assembly and to the actuator handle assembly is provided.
