Abstract: ABSTRACT OF THE DISCLOSURE      An oxygen sensing element for use in a device to detect oxygen concentration in a gas atmosphere or to detect air/fuel ratio in an internal combustion engine based on the oxygen concentration in the exhaust gas. The element is a lamination of generally flat and relatively thin layers including a shield layer of a ceramic material, first solid electrolyte layer, inner electrode layer, second solid electrolyte layer and outer electrode layer laid one upon another in the mentioned order.  The second solid electrolyte layer and the two electrode layers constitute a concentration cell.  The first solid electrolyte layer is formed of essentially the same material as the second solid electrolyte layer, so that there is no or little difference in thermal expansion coefficient between the two layers which tightly sandwich the inner electrode layer therebetween.  Hence, the inner electrode layer does not tend to separate from either of the two solid electrolyte layers even when the element is subjected to great and repeated changes in temperature.

Abstract: ABSTRACT Process for preparing cyclopropane carboxylic acid ester derivatives This invention relates to the preparation of cyclopropane carboxylic acid ester derivatives, which are useful as pesticides.     There is provided a process for preparing a mixture of cis-isomers of a compound of formula   (I) wherein R1 and R2 are independently selected from chlorine, bromine and methyl, consisting predominantly of the lR cis S- and lS cis R- isomers, which process comprises dissolving a mixture of lS cis S- and lR cis R- isomers of the compound of formula I, alone or in the presence of lR cis S- and lS cis R-isomers, in an organic amine base containing from 5 to 7 carbon atoms and being a secondary amine containing two branched alkyl groups or a tertiary amine, crystallising out from a resulting solution of cis- isomers of formula I in the organic amine base a 1:1 mixture of the lR cis S- and lS cis R- isomers, and evaporating off the organic amine base.     The process of the invention yields a product which may contain up to twice as much of the most active isomer of the compound of formula I as a racemic mixture of all four cis-isomers, and is a readily effected process which does not involve any sterospecific synthesis or optical resolution steps.

Abstract: DIGITALLY CONTROLLED POWER SUPPLY                 Abstract of the Disclosure A high power factor AC to DC power supply having a high frequency pulse producing circuit comprising an in-ductor supplied with rectified raw AC power through a semiconductor switch which provides dynamic power factor correction by maintaining the width of the on-times of the switch substantially constant throughout each cycle of the input AC power.  The peak energy stored in the in-ductor during the on-times are a function of the ampli-tude of the instantaneous voltage of said rectified AC power, so that each time the switch is turned off, the output pulse of current supplied to the load by the in-ductor has a time duration which is a direct function of the instantaneous voltage value of the rectified AC power.  The output load has a filter whose time constant is greater than a cycle of said rectified AC power, and the average on-time of said switch is varied over a num-ber of cycles of said AC power to regulate the output voltage of said supply.

Abstract: ABSTRACT OF THE DISCLOSURE     An automatic locking safety belt retractor includes a mounting frame having side walls between which a spring biased retractor reel is journalled and a racket wheel rotatable with the reel is located on the outer face of a side wall.  A plastic guide plate is secured to the side wall outside face and has a circular opening engaged by the ratchet wheel, a slot tangentially extending from the opening and a housing recess projecting laterally from the upper end of the slot.  Outwardly projecting reinforcing flanges are integrally formed along opposite parallel edges of the slot and along the bottom inclined edge of the junction between the slot and opening.  A high strength bumper member is located in the recess and forms the top of the slot.  A stop member is slidable in the slot and inclu-des a tooth which in its depressed retracted position is out of engagement with the ratchet wheel and when slightly raised by an acceleration sensor engages the ratchet wheel which advances the stop member with belt extraction to strike the bumper member which stops the stop member and brakes the reel.

Abstract: Abstract of the Disclosure A rain water roof outlet for a building for conducting rain water from a roof as an airless flow, i.e. as a full water flow, comprises a vertical pipe which at its upper end is connected to a wider trough mounted at the level of the roof.  In the trough, above the mouth of the vertical pipe, is mounted a lid, which by special formation of its shape or by means of additional elements is adapted to increase the friction against the water flowing towards the mouth of the vertical pipe.  This friction counteracts the tendency of creating whirls in the water stream and thereby contributes to producing a full water flow in the vertical pipe by preventing air entry.  The above mentioned lid may preferably comprise a net element.
