Title: Artificial seaweed from drawn expanded strands of
IPC: E02B3/04
Filed: 1969-04-22
Abstract: Artificial seaweed consists of a number of elongated, flexible synthetic thermoplastic elements capable of floating in water, whose ends are woven together from thread-formed elements to form a woven strip, to which anchoring elements are fixed for maintaining the elements near the bottom of a body of water. The artificial seaweed is used for the prevention of coastal erosion. The anchoring elements are placed on the sea bed, so that the elongated elements, which tend to float, can assume a vertical position in the water. This arrangement reduces the flow of water, and promotes deposition of sand.

Title: Well perforating technique
IPC: E21B43/116
Filed: 1969-06-18
Abstract: Well perforating technique.. Gf-. By a tool lowered to the required perforating level and then fired to produce the perforations. Prior to firing, fluid is introduced into the well up to a level above the perforating range and is then raised to a pressure sufficient to drive it to the surface and into the perforations and the formation when the tool is fired. The fluid is capable of removing any material such as might clog the perforations made. Preferably the fluid used is known to react with possible clogging materials. This material is specifically driven right out of the well at high pressure. The drive fluid is followed by another fluid which prevents production loss and also prevents clogging of the perforations. This second fluid or mud is followed by another fluid which preferably is capable of consolidating sand for fracturing purposes in the formation. The pressure of the fluid responsible for preventing clogging is raised specifically to a level sufficient to fracture the perforated formation.

Title: Thermostatic control device for electric heater - temp. range of one switch is within temp. range of second switch
IPC: H02H5/04
Filed: 1973-10-24
Abstract: The thermostatic control device has two thermostatic switches (1, 2) to control the current flowing through a heater resistance (4). The control band of the first thermostat is set within the control band of the second thermostat, such that if the first thermostat is set at 240 deg. C-235 deg. C then the second thermostat is set at 245 deg. C-220 deg. C. The double control band with one device ensures good reliability because the likelyhood of fusing of the second thermostat is almost nil as it only operates under load if the first thermostat has failed. The device can then be used for narrow band control of temperature without any high risk of failure due to the high number of switching which can then occur.

Current is fed to each bridge through a further resistor and an amplifier to maintain a constant temp. in the sensing resistor above ambient temp. The sensing resistors are exposed to the gas under test and the presence of a combustible gas causes an increase in temp. of the second sensing resistor. This increase is detected by comparing the amplifier outputs and is indicated in units of concentration of the gas. The working life of the sensing resistor is greatly increased compared with customary systems.
