Title: Downhole chemical cutting tool
IPC: E21B23/04
Filed: 1989-11-20
Abstract: A downhole chemical cutting tool having an 
anchoring system employing interchangeable slip arrays (38) 
of progressively larger outside diameters that can be 
used economically to adjust the range of the anchoring 
system. The range can be further adjusted by utilizing 
interchangeable slip expansion mandrels (44). This anchoring 
system both anchors and centralizes the chemical cutting 
tool. The cutting tool includes a slip shaft (32) that 
provides fluid communication between the propellant 
section (24) and chemical section (26), thence to the slip piston (36) 
that receives the interchangeable slip arrays (38). The slip 
shaft and slip piston are threadedly connected to a set 
coiled tension spring (34). Interchangeable slip expansion 
mandrels (44) connected to the slip shaft (32) below the slip 
arrays are constructed with ball bearings (44a) on the surface 
that receives the slip arrays expanding the slip 
segments into a gripping engagement an usually large 
angle as the slip piston is actuated by the application 
of fluid pressure during the cutting operation. The 
interchangeable slips are configured so that the 
gripping teeth (38k,j,i,h) will simultaneously engage the internal 
surface (110) of the wellbore pipe being cut. During the 
cutting operation the application of fluid pressure 
activates the slip assembly and discharges the chemical 
cutting fluid from the chemical section into the fluid 
jet section of the tool at high temperature and 
velocity. After the release of fluid pressure the slip 
assembly reliably releases the tool due to the large 
angle of engagement of the slip segments.

Title: Copying holograms
IPC: G02F1/13
Filed: 1989-11-30
Abstract: There is described a method of preparing a copy hologram from a master 
hologram which is characterised in that the light employed in the 
copying process is modified by passing at least one exposing beam 
through a light modulating array (28), some members at least of said 
array having had their light transmissivities modified in accordance with 
information derived from a reconstruction of the master hologram.  
     One useful method of modifying the light transmissivities of the light 
modulating array members in accordance with information derived from a 
reconstruction of the master hologram is to reconstruct the master 
hologram and then prepare video signals representative of this image 
by use of a video camera placed along the axis to be used for viewing 
the holographic copies, digitising the video signals and storing them 
and then using the stored signals to modify the elements of the light 
modulating array.

Title: Improved system for triac trigger control in combination with a sensing element
IPC: G05F1/45
Filed: 1991-11-27
Abstract: The invention relates to a circuit of the kind wherein a load (L) is supplied via a triac (TC) with current from an AC voltage supply source (A, B) under the control of a triac control means (IC) in combination with a sensing element (RT). In previous circuits the sensing element is energised by a current from a DC source which is derived by rectification and smoothing of the alternating current of an alternating voltage supply source, which has limitations in integrated circuitry. In the present invention the sensing element (RT) is energised by an alternating current to produce a sensed alternating current. The triac control means (IC) includes an integration means (6) for producing a control signal which is representative of the integral of the difference between a value corresponding with the average peak to peak magnitude of the sensed alternating current and a reference value. The triggering or otherwise of the triac (TC) being determined by a latch (LCH) actuated in response to the magnitude of the control signal relative to one or more threshold levels. The present invention may be used in thermostats or other sensing devices. <IMAGE>
