Abstract: PERCUSSION HAMMER DRILL            WITH UPPER END COCKING SPRING             Abstract of the Disclosure A percussion hammer drill stem has a reciprocally movable internal hammer which forms a large part of its mass.  A single precompressed cocking spring is positioned around the upper end of the hammer and supports it within a bore of a casing.  When the drill stem is dropped in drilling operations, the spring is restricted against down-ward movement, but the hammer moves a short distance after an initial impact to provide a follow up impact.  During this movement the spring is compressed further to absorb some of the kinetic energy built up by the hammer during its drop.  The spring is located away from a debris chamber at the lower end of the hammer where dust and debris tends to accumulate from the internal impacts between the hammer and the casing.

Abstract: ABSTRACT A squeeze-outable container with a hollow space for, eg., pasty, powdery or liquid goods is formed out of a single blank, which is bent over in a somewhat U shape. The blank consists thereby out of a bendable, mainly stiff, carton-like or carton con-taining material or also out of carton itself. The edge areas of the blank lie flat upon one another after the forming procedure and are then tightly joined. Only in the area of the crossover of one wall to another a U cross ridge is produced across the base, which exerts a distancing function on the hollow space of the container. An at first flat channel passage is provided in the edge area of the container beyond the base, in whose area the edges of the blank are not joined together. This channel is closed before use and can be opened by tearing or cutting off a tongue into which it leads.

Abstract: ABSTRACT           Laser radiation whose wavelength is in the submillimeter wave spectral region is sent through an intercavity dielectric tube positioned inside a coil.  The tube contains a gas having large dipole moments and which may be of the same kind as the input beams lasing gas.  In response to current therethrough the coil produces an axial magnetic field.  The direction of the magnetic field is parallel to the propagation of light transmitted through the dielectric tube.  The frequency of the submillimeter wave laser radiation in the tube is shifted from its normal value.  The amount of shift is determined by the current in the coil since the resulting magnetic field produces a change in the mean index of refraction of the gas.  Thus, the change in index of refraction causes a shift in the laser radiation frequency because the gas within the coil is also located within the submillimeter wave lasing cavity.

Abstract: ABSTRACT OF THE DISCLOSURE         Pure-green light emitting diodes comprise an n-type GaP layer formed on an n-type GaP substrate and a p-type GaP layer formed by using a liquid phase epi-taxial method, the average donor concentration of the p-type GaP layer being less than or equal to 5 x 1016 cm-3.  Liquid phase crystal growth of the above p-type GaP layer is realized by applying a method of keeping the melt used for the liquid phase crystal growth of the n-type GaP layer at a constant temperature and the ambient atmosphere at a reduced pressure for a pre-scribed period of time thereby to volatilize donor impurities from the melt and to compensate the donor impurities.         Pure-green light emitting diodes easily distinguishable from yellow-green and having high brightness can be manufactured by applying the over-compensation method which is suitable for mass produc-tion.

Abstract: ABSTRACT             The invention is, in part, a unique, solid electro-lyte-integral cell electrode/heater configuration which pro-vides a zone of uniform maximum heating at a predetermined location within the electrolyte and which, when used with a suitable resistive  heating  electric  current,  confines  the current to  the  integral  electrode/heater  prolonging  cell life.  Another aspect of the invention is the use of a radio frequency  alternating   electric   current  for  resistively heating  an  electrochemical  cell.  Preferably,  the  radio frequency selected is sufficiently high so as to eliminate any offsets in the emf developed by the cell which are caused by the heater  current.   The  invention  also  includes  an apparatus  for  measuring  the  concentration of particular gases, such as oxygen, incorporating either and, preferably, both other inventive aspects of the invention.  The preferred cell configuration reduces the complexity of such an apparatus by eliminating the auxiliary heat source and provides a more accurate and  reliable  electrochemical  sensing  cell.  Radio frequency heating  allows  the  operations  of  cell  heating and emf measurement to proceed independently and concurrently and provides a continuously responding, self-heating detection apparatus.
