Patent GB-2060180-A (GB)
Title: Method of measuring the photoactivity of pigments
IPC: G01N17/00
Filed: 1980-10-03
Abstract: The photoactivity of pigments present in plastics materials and surface coating materials is determined by irradiation of samples of materials containing the pigments with light of predetermined wavelengths utilising an irradiation band in which the short wave limit is arranged to fall beyond the absorption limit of the pigment under test but such that the intensity is low in the region of the absorption limit of the matrix material but as great as possible in the region of the absorption limit of the pigment and in the adjoining short wave region whilst intensity in the adjoining long wave region is as low as possible. The amount of incident radiation is measured throughout the test period in the region of the absorption limit of the pigment and in the adjoining short wave region so that testing is carried out with a known amount of radiation.

Title: Threaded Fasteners having a Sealing Cover
IPC: F16B33/00
Filed: 1980-10-13
Abstract: A screw-threaded fastener 10 includes a head 12 having top surface 32 contoured (at 34) for interlocking engagement with a driver, a threaded shank 14 extending from the clamping surface 36 and a moisture-impervious cover 16 which overlies the head portion 12 and extends axially away from the clamping surface 36 to form a flange 42 for sealing the fastener 10 to a workpiece surface into which the fastener is driven. The flange 42 is inwardly deformable upon contacting the work piece surface so as to deflect work piece fragments, produced as the fastener is driven into the work piece, away from the seal between the flange 42 and the work piece surface to preclude the fragments from interfering with the seal. A cavity 44 receives the work piece fragments as the flange is deformed. <IMAGE>

Title: Power factor controller for AC induction motor
Inventor: SPANN ROBERT J
IPC: H02P23/00
Filed: 1982-01-21
Abstract: The operating power factor of an AC induction motor (34) is controlled by selectively controlling the firing angle delay of a gate signal to a triac (36) during the cycle of the power source (32). Source voltage zero crossing is sensed and a plurality of consecutively sequenced discrete windows are initiated. If the current zero crossing occurs in the first window then a sudden load on the motor (34) is indicated, and any delay in the firing angle of the triac (36) is substantially eliminated. This enables conduction of the triac (36) during substantially the entire cycle of the source voltage thus providing instantaneous full power to the motor (34). If the current zero crossing occurs in the second window then the power factor is too great, and more power is needed at the motor (34). The gate firing angle is reduced, whereby the triac (36) will conduct for a longer cycle portion and hence deliver more power to the motor (34). If the current zero crossing occurs in the third window then an optimum power factor is indicated and the gate firing angle is not affected. If current zero crossing does not occur in any of the first three windows, then it will occur somewhere in the fourth window and too much power is getting to the motor (34). Upon termination of the third window without zero crossing of the current, the gate firing angle delay is increased so that the triac (36) will be ON for a shorter portion of the cycle, and hence less power is delivered to the motor (34). <IMAGE>

Title: Method for cultivating a micro-organism containing a recombinant plasmid
Inventor: KAKUTANI TETSU
IPC: C12N1/00
Filed: 1982-11-04
Abstract: A selective method for cultivating a micro-organism having a recombinant plasmid comprises incorporating a phage deoxyribonucleic acid fragment coding for a protein necessary for the maintenance of the lysogenic state of a lysogenic phage into a plasmid which is replicatable in a host micro-organism, then the resulting recombinant plasmid is introduced into the micro-organism in which a lysogenic phage having mutation in the deoxyribonucleic acid region coding for a protein necessary for the maintenance of the lysogenic state of said lysogenic phage is in a lysogenic state, and finally the micro-organism is cultivated under conditions where the formation of said lysogenic phage is induced. Thus, when a gene fragment coding for a valuable product is further incorporated into the foregoing replicatable plasmid carrying a suppressor gene and a micro-organism having the resulting plasmid is cultivated, only the micro-organism having the plasmid can selectively be grown, leading to an increase in productivity in fermentation of valuable products in genetic engineering.

Title: Process and heat exchanger for the progressive cooling of a hot gas stream
Inventor: MULLER WALTER
IPC: C09C1/00
Filed: 1983-02-02
Abstract: The casing 2 constructed e.g. as a reactor has an inner area 3, which is bounded by an inner jacket 6 which, whilst forming an intermediate area 7, is surrounded by an outer jacket, on which is arranged a heat exchanger for cooling fluid (eg water) with an inlet connection 12 and an outlet connection 13. The mixture e.g. of air and oil entering through mixing chambers 20 is ignited and an exothermic reaction takes place. The heat liberated during the reaction must be removed in controlled manner in order to ensure at outlet A a temperature which is within a relatively narrow temperature range. This is achieved by the series connection of two radiation processes, i.e. from reaction gas to the inner jacket 6 and from there to the outer wall 4. The temperature peaks occurring with different mixing ratios having only a limited influence on the temperature profile towards the reactor outlet and there is no need for external action, e.g. via a cooling system control. <IMAGE>
