Title: Electric hoist
IPC: B66D1/58
Filed: 1988-03-03
Abstract: An electric hoist (1) contains a housing in which an electric motor (2) with a sliding armature (12) as well as a reduction gearing (3) driven by the electric motor (2) are arranged. The output shaft (28) of the gearing (3) actuates a driving device (39) for a lifting mechanism. An overload slip clutch (4) is provided in the drive line between the electric motor (2) and the output shaft (28), which overload slip clutch (4) has two friction-clutch members preloaded in frictional connection with one another, of which one is coupled to the motor (2) and the other is coupled to the output shaft (28). In addition, a brake device (5) is provided in order to brake the output shaft (28) via the gearing (3) when the motor (2) is switched off. So that the slipping moment of the overload slip clutch (4) can be set independently of the brake force of the brake device (5), the brake device (5) is connected to that part of the drive line which lies between the slip clutch (4) and the output shaft (28). The brake device (5) is actuated by sliding of the armature (12) when the motor current is switched off or on. <IMAGE>

Title: Plural arc radiation protector
IPC: H04N5/32
Filed: 1989-11-25
Abstract: A radiation protection (50) system is operative within an 
optical section of a radiation imaging system (20) for 
protection of an array of detectors (22) of the radiation. 
The protection system is formed of one or more spark 
boards (80) arranged in series along a path of radiation 
propagation, the spark boards having a central window (84) 
through which the radiation propagates. On a front 
side of each spark board are arranged a set of 
electrodes (90) disposed about a periphery of the window. 
Ground pads are disposed on a back side of each board 
in registration with the electrodes on the front side 
to form therewith a set of capacitors. A 
capacitive-discharge power-supply circuit (70) is connected 
to a first pair of electrodes in a first one of said 
boards. In the presence of excessive incident 
radiation power, a capacitor of the power supply 
circuit is switched to apply a high voltage across said 
first pair of electrodes, the voltage being high enough 
to initiate an arc across the window in said first 
board. The capacitors and electrodes are connected 
serially to allow a current of one arc to charge a 
succeeding capacitor which, upon being charged, 
initiates a further arc in a process which continues 
until all arcs have been struck. The array of arcs 
blocks radiation propagation so as to protect the 
detectors.

Title: Hydraulically damped mounting device
IPC: F16F13/10
Filed: 1989-01-12
Abstract: A hydraulically damped mounting device has two 
anchor parts (1,3) joined by a resilient spring wall (9). 
The resilient spring wall (9) and a partition (6) define 
a working chamber (13) for liquid, the working chamber 
(13) being in communication with a compensation chamber 
(14) via a passage (73,74,75,76). The compensation 
chamber (14) is bound by a flexible bellows wall (5). A 
flexible diaphragm (66) of annular shape defines, 
together with the partition (6), a gas chamber. The 
annular nature of the diaphragm (66) means that the 
centre of the partition (6) which bears the most load 
during relative vibration of the anchor parts can be made 
strong.

IPC: C12Q1/6876
Filed: 1989-02-02
Abstract: A DNA sequence encoding the human platelet-derived 
growth factor receptor (hPDGF-R) has now been isolated 
and sequenced. An expression construct comprises the 
sequence encodes a receptor that can be secreted or 
incorporated into the membrane of a mammalian cell. 
The incorporated receptor is functionally equivalent to 
the wild-type receptor, conferring a PDGF-sensitive 
mitogenic response on cells lacking the receptor. The 
construct can be used for enhancing PDGF response of 
cells, determining the regions involved in transducing 
the signal in response to PDGF binding, providing 
mutated analogs and evaluating drugs for their 
physiologic activity.

Filed: 1990-03-21
Abstract: Apparatus comprising an indium bump (11) that may be etched in a low 
concentration of hydrochloric acid (typically 1%) to remove oxide 
buildup, and a pad generally comprising a three layer arrangement 
of gold (16) over nickel (15) over titanium (14). The indium bump (11) 
and the gold pad (20) are pressed together for a short period of time, 
typically on the order of ten seconds, and then the pressed components 
are allowed to alloy weld over an extended period of time.  
Alternatively, the bump and pad may be heated at approximately 100 
degrees Celsius for a period of about one hour to accelerate the alloy 
process. The heating diffuses the gold from the pad into the indium bump, 
thus forming a true alloy weld between the two that has incredibly strong 
bonding strength. Such bonding materials and men are useful in bonding 
integrated circuit components, and the like.
