Title: Pressurised water reactor with rapid power increase - due to reduced local xenon poisoning obtd. by control rod operation
IPC: G21C7/08
Filed: 1976-02-03
Abstract: A pressurised water power reactor has two main groups of control rods, an L-group of high control reactivity and partial penetration of the core, and a D-group of lower control reactivity and full core penetration. The rods of the D-group can be interchanged (in their functioning) automatically by a timer, esp. operating in a cycle of 10 mins.-2 hrs. More spec., this timer can be connected to a computer, which determines which rods should be interchanged as a function of the local burn-up. The effectiveness (control reactivity) of the rods is reduced by loxal xenon poisoning in the core. By varying the action of the rods, this local loss of rod effectiveness is reduced, enabling a better, more rapid control of the reactor to be attained.

Title: N-acylated alpha-amino acids prepn. - by reacting olefins with adducts of amides and glyoxylic acid
IPC: C07D265/08
Filed: 1976-06-18
Abstract: Acyl derivs. of 1-6C alpha-amino acids are prepd by (a) forming an adduct between a prim. amide and glyoxylic acid or a glyoxylate ester, and (b) reacting the adduct with an olefin of formula R1R2C=CH2 (where R1 is Me, halogen or acetyloxy and R2 is H, Me or halogen, provided that R2 is not halogen when R1 is acetyloxy) in the presence of an acid catalyst. The process is esp. useful for preparing aspartic acid and leucine derivs., which are intermediates for the free amino acids. The process uses inexpensive starting materials. In an example, N-benzoyl-gamma-hydroxy-DL-leucine lactone is prepd. by reacting glyoxylic acid with benzamide and reacting the resulting alpha-hydroxyhippuric acid with isobutylene in the presence of H2SO4.

Title: Dimmer circuit using PTC and NTC resistors - gradually reduces light intensity to zero after switch=on by controlling triac turn-on point
IPC: H05B39/08
Filed: 1977-10-04
Abstract: The dimmer circuit gradually reduces the intensity of a light to zero over a given period of time after the light has been switched on. The circuit contains a PTC resistor (30) and an NTC resistor (17) both connected at one end to the secondary (32) of a transformer whose primary (31) is in series with the main switch (6).

Title: Bleached wood pulp from shavings in a single stage - in a thermo-mechanic pulper with addn. of bleach during pulping (SW 16.5.78)
IPC: D21B1/16
Filed: 1977-10-14
Abstract: Bleaching wood pulp is mfd. from wood shavings in a single stage in a thermomechanic pulper by adding a bleaching agent (I) to the wood to bleach it as it is being pulped. Specifically the shavings, preheated to 100-110 degrees C., are pulped in a double disc refiner. A soln. or aq. suspension of (I) is charged to the refiner such that it comes into contact with the shavings at the centre of the refiner. (I) is added at 0.5-5 wt.% based on the wt. of the dried wood solids charged. (I) is esp. H2O2 added as an aq. soln. (0.5-10% by wt.) pH 9-12. (I) can also be an alkali metal dithionite, or (hypo)chlorite. The prod. has improved absorbency and is used in the paper industry for absorbent hygienic products, e.g. disposable paper towels. The single stage process gives products at least as good and in a much faster time than conventional methods.
