Title: Motorised regulator for heat exchangers - which are controlled by temp. sensors via comparator and relay circuit (DK 29.3.82)
IPC: G05B11/18
Filed: 1980-08-29
Abstract: This motorised regulator is for use in controlling the primary supply flow to a heat exchanger which forms part of a district central heating system, supplying a number of houses or flats. A signal from temperature sensors (2,3) is compared with the voltage on the wiper (7) of a potentiometer (5), which is mechanically coupled to the position of the regulator valve. If the d.c. signal from the temp. sensor is significantly different from the voltage on the potentiometer wiper, the output of the comparator operates one of two relays which feed an a.c. supply to the valve drive motor. One relay causes the valve to open and the other to close. When the wiper and detector signals reach equilibrium, the relay de-energises and the motor stops.

Patent NL-8201712-A (NL)
Title: Transparent vessel has compartments separated by diaphragm - pierced from outside to mix components and produce chemiluminescent reaction
IPC: B65D51/28
Filed: 1982-04-26
Abstract: The, preferably cylindrical, reaction vessel contains two compartments containing different chemical compounds separated by a diaphragm which can be brought into mutual contact by piercing the diaphragm. The arrangement is particularly intended for holding compounds which, on mixing, produce chemiluminescence, e.g. by reaction of peroxyde with oxalyl derivatives, the vessel being transparent and being used as a "light stick" (similar to a product of Cyanamid Ltd.). Piercing of the diaphragm may be effected in different ways, e.g. by an element with sharp edge contained above the diaphragm in one compartment formed as a cap with a top and/or side shaped or grooved to permit depression such that a rod secured in the top depresses the element. Reaction vessel containing two compounds mixed by breaking diaphragm, particularly to produce chemiluminescence. The arrangement simplifies that of prior art in which a polythene tube containing one component must be bent to break an internal glass phial containing the other component.

Title: Resealing leaking bell and spigot joint - by injecting sealant into joint using seal maintaining tooling
IPC: F16L55/18
Filed: 1983-04-26
Abstract: A leaking bell (12) and spigot (14) pipe joint is sealed by injecting a polyurethane elastomer sealant, with a viscosity between 1900 and 2800 cps. and pref. contg. 22 wt.% rubber crumb of 2 mm mesh size, directly into the joint where it flows freely before curing. The joint is accessed by drilling and tapping an injection point (18) in the bell (12) above the joint cavity and fitting a hot tap valve adaptor (20) having a passage (22) which can be closed or opened by a rotatable valve (30). The top of the adaptor is threaded (34) for attachment of a hot tap tool (28). The tool has a sealed cap (35) through which a rod (36), having an attached drill bit (32), passes, enabling the bore (18) to be drilled through to the joint cavity. For injecting the sealant, the hot tap tool is replaced by an injection gun which threads into the adaptor (20). The method and appts. enables leaking bell and spigot joints in pipes, partic. gas pipes, to be resealed without fully excavating, cleaning, and priming the exterior to apply an encapsulating resin. The seal can be made quickly and simply restoring sealing gaskets to their original condition and allowing flexing to occur to accommodate ground movements.
