Patent EP-0045979-A3 (EP)
IPC: G02B5/128
Filed: 1981-08-05
Abstract: A retroreflector consists of a support surface 12 coated 
with a layer 11 of small retroreflecting particles such as glass 
spheres. The support surface comprises a plurality of 
regularly repeating, like structural elements 13 which are 
inclined to the overall plane of the retroreflector. The surface 
elements 13 can be of various shapes and serve to increase 
the angular range over which retroreflection can occur. The 
optical characteristics of the proposed retroreflectors can be 
tailored so that they are eminently suitable for use in certain 
beam scanning applications such as continuous monitoring 
of doorways and windows by an optical beam scanning 
device located at one corner thereof in order to detect, for 
example, intruders.

Title: Prestressed accumulator
IPC: F15B1/12
Filed: 1981-02-18
Abstract: A hydraulic accumulator comprises two-halfs shells, the diaphragm therebetween defining two cavities. One cavity contains presssurized gas and the cavity receives hydraulic fluid under pressure. The two-half shells are held together by a mechanical element, such as a belt which has been previously prestressed to a tension selected according to the maximum pressure to which the accumulator will be subjected. The use of the prestressed mechanical element changes the dynamic stresses ordinarily found in a hydraulic accumulator to static stresses, thus minimizing the occurrence of creeks and failure of the device.

Title: Method and apparatus for restoring data in a computing system
IPC: G06F11/14
Filed: 1983-05-06
Abstract: Method and apparatus for assuring atomicity of user requested multi-row update operations to tables such as in a relation database (24), guaranteeing that for any update operation that succeeds all stated effects will have occurred and that for any update operation that fails the system state as perceived by the user remains unchaged. This is accomplished by establishing, in response to a multi-row update operation request, an execution module containing machine language code instructions implementing the update operation request with a savepoint request at the beginning of the execution module. For each set of instruction in or called by the execution module which modified the user perceived system state, undo information is logged to a soft log (20). Upon completing the execution module, the savepoint is dropped, causing all soft log information recorded since the savepoint to be deleted and releasing all resources held to guarantee restoration of the user perceived system state at the time of the savepoint request. Responsive to the detection of an error during execution of the module, the soft logged undo information is used to restore the user perceived state to that existing at the time of the savepoint request.

IPC: C09K8/32
Filed: 1986-11-13
Abstract: By the use of small amounts of novel amido amine 
reaction products of a fatty acid, an alkanolamine and a 
polyalkylene polyamine, improved drilling mud formula­
tions are obtained. In oil mud drilling formulations contain­
ing organophilic clays, one is able to maximize the viscosity 
and gelation of the formulations, resulting in less prepara­
tion time and less material usage, especially the clay. In 
accordance with the invention, one is able to thicken or gel 
oil-mud systems at usual operating temperatures even 
when using low viscosity/low aromatic oils as the external 
phase, and to maximize the yield of organophilic clays 
readily in a short period of time, at low shear rates. The 
amido amine extends the utility of organoclays in low vis­
cosity oil-mud systems. They produce more shear thinning 
fluids, higher yield points and quicker gel strengths while 
maintaining low plastic viscosities.

ferential pressures is sensed by a capacitor 26, 40 and a cor­
responding capacitor on the lower side of the diaphragm, 
which act in push-pull mode. The outer faces of plates 34 and 
36 are covered by isolation diaphragms 62 of greater compli­
ance than the sensing diaphragm. Diaphragms 62 are 
clamped around their edges and bulge outwards under pres­
sure of liquid filling the space between each reference plate 
and its isolation diaphragm 62, a central bore 67 in the refer­
ence plate, and the space between the reference plate and the

machine is wound with an electrically pure iron strip coated 
with an insulating paint. The strip is not only an electrically-­
conducting winding, but also a magnetically-conducting iron 
core in the electric machine. In comparison with the tradi­
tional electric machine, this invention has advantages such as 
small in volume, large in capacity, high in efficiency, far stron­
ger in overload capacity in a short time, longer service life of 
the electric machine etc. This invention also eliminates a set 
of drawbacks such as additional torque, noise, Carter's coeffi­
cient in the air gap, the stray copper losses and stray iron 
losses etc. formed by the tooth harmonics in the traditional 
electric machine. When the efficiency is not a specially high 
one, the electric machine does not waste copper material.
