Abstract: IMPROVED BATTERY STORAGE RACK     A B S T R A C T   A storage rack assembly includes a plurality of vertically disposed corner posts and a plurality of horizon-tally disposed beams interconnected between the corner posts for defining a box-like structure having a front face and a rear face.  A plurality of elongate partition members are interconnected in spaced parallel relationship between a beam forming part of the front face and a beam forming part of the rear face, each partition member comprising a longitudinal base portion, a longitudinal leg portion extending upwardly from the center of the base portion and a pair of longitudinal shoulders extending upwardly from each edge of the base portion.  Each partition member further includes longitudinal mating means depending from the center of the base portion for mating with suitable slots formed in the beams of the front and rear faces of the assembly. Each pair of adjacent partition members thereby defines a channel for receiving items of inventory, the channel com-prising the center legs of the adjacent partition members for guiding an item of inventory therebetween and one of the shoulders of each partition member on which the item of inventory is slidable between the rear and front faces of the assembly.

Abstract: INJECTION FREQUENCY LOCKED TEA LASER                        Abstract A very high power stable frequency TEA laser receiver-transmitter combination for applications requiring coherent detection.  The transmitter includes a conventional CW laser tube positioned in a resonant cavity also containing a high power TEA laser.  The high power output pulses are injection locked to the CW laser for frequency stability.  The frequency of the laser pulses is tuned by changing the optical length of the resonant cavity in response to the frequency of a portion of the output signal.  Electrical to optical power efficiency is improved as a result of the high percentage of power extracted from the cavity.

Abstract: ABSTRACT     The invention is concerned with a method of scrubbing H2S from coke-oven gas using the sulphur-ammonia method, wherein hydrogen sulphide is removed in an H2S scrubber using ammonia water, the ammonia in the coke-oven gas is removed by washing with water and the washing liquid flowing from the H2S scrubber is supplied to the top of a deacidifier in which hydrogen sulphide is expelled from an NH3 stripper, using water vapour and, if required, NH3 vapour, and is further treated, the flow from the deacidifier is recycled to the top of the H2S scrubber, the plant includ-ing a scrubbing tower having a bottom part which receives the H2S-containing vapour driven off by the deacidifier when the plant for processing the aforementioned vapour is not in operation; the vapour being washed with cool water in the scrubbing tower to produce strong liquor and the gas leaving the top of the scrubber being supplied to the coke-oven gas for purification.  The method of the invention is characterized in that during normal operation, when the vapour leaving the deacidifier is further treated, the scrubbing tower is used to strip ammonia from the recycled liquor coming from the deacidifier, part of the stream of recycled liquor being conveyed from the top and middle of the tower downwards, and being treated in countercurrent by part of the coke-oven gas from the NH3 scrubber, whereupon the liquid flowing from the scrubbing tower is added to the recycled liquor supplied to the top of the H2S scrubber, and the NH3 stripped by the coke-oven gas is supplied to approximately the middle of the H2S scrubber.  Since ammonia is removed from the recycled water leaving the deacidifier and supplied to the top of the H2S scrubber, there is a reduction in the concentration of NH3 in the washing liquor, so that it can absorb more NH3 from the gas for purification.  Since gaseous ammonia is returned to the middle of the H2S scrubber, the NH3 concentration of the gas is increased, thus favouring the selective washing-out of H2S.

Abstract: "IMPROVEMENTS IN OR  RELATING TO MACHINE TOOLS"               ABSTRACT OF THE DISCLOSURE    The disclosure relates to a grinding machine in which a workpiece such as a multi-stage compressor or turbine rotor to have grinding operations carried out at different locations along the workpiece at different radii and at different angles is mounted between centres on a slideway to present the locations on the workpiece to be ground to a motor driven grinding wheel mounted in a grinding head.  The grinding head is mounted on a slide to traverse the grinding wheel towards and away from the periphery of the workpiece at a location where the grinding operation is to be carried out and the grinding wheel is mounted on the slide for rotational adjustment by mechanism about an axis extending tangentially to the periphery of the grinding wheel by a location where the grinding wheel acts on the workpiece for adjustment of the angle of cut of the grinding wheel.          Since the grinding wheel turns about the axis when its angle is adjusted, the position of the angle of cut is not otherwise varied by the angular adjustment of the grinding wheel.  A control mechanism is provided for enabling the grinding wheel to be accurately pre-set to a number of pre-determined angles to suit the workpiece to be ground.

Abstract: ABSTRACT           Process and apparatus for monitoring the potential with respect to the soil of a metallic structure situated in the soil and cathodically protected by an externally applied DC voltage. A measuring electrode situated adjacent to this structure in the soil is electri-cally connected to the structure and to a measuring circuit with which the potential difference between the measuring electrode and a reference electrode placed on or in the soil is measured. The measured potential is continuously compared during a measuring cycle of, e.g., one month with a set reference potential corresponding to the desired protection potential in a comparison circuit. The amount by which the measured potential is higher than the reference potential is converted into a pulsed signal the frequency of which is proportional to the said amount and the number of pulses during the measuring cycle is counted in a  pulse counter, the time interval between the start and end of a measuring cycle is recorded and after the measuring cycle the average value of the amount by which the measured potential has been higher than the reference potential during the measuring cycle is deter-mined from the number of pulses counted in the pulse counter and the recorded time interval.
