Patent SE-7506485-L (SE)
Inventor: BENDER M L
IPC: E21B10/26
Filed: 1975-06-06
Abstract: Disclosed herein is a rotary-percussion earth boring bit that has an improved geometric configuration to extend cutting insert life and reduce cutting insert breakage. The bottom surface contains a flat transverse face with a bevelled edge. Two rows of circumferentially spaced cutting inserts protrude from the bevel. One of the rows is spaced inwardly from an outer row to define an inner row, which has inserts positioned between the circumferentially spaced inserts of the outer row. The longitudinal axes of these inserts are substantially perpendicular to the bevel and inclined outward at an acute angle to the axis of rotation of the bit. A generally longitudinally extending groove is formed between each two adjacent inserts of the outer row. This arrangement produces a symmetry that tends to minimize the number of reflective surfaces. This equalizes the stresses generated by the impact induced shock waves transmitted through the bit.

Abstract: In hand drills 2 there is a need to remove the dust created by the drilling. Normally, there is a removal of the dust after the drilling is completed and the dust can then be spread over quite a large surface. The present invention allows one to get rid of the dust formed as soon as it arises and thereby prevents such spreading. The invention consists of an accessory unit 1 which is fastened to a non-moving part of the hand drill 2. The accessory unit 1 can be placed under vacuum and is secured by means of vacuum over the hole being drilled. The dust is removed by suction by the arrangement producing the vacuum. The accessory unit 1 has a space which is reduced by the action of the arrangement generating the vacuum. The reduction is utilised to guide the manual drill 2 against the surface where a hole is to be made. <IMAGE>

Abstract: The invention relates to an espagnolette for doors, windows and the like, the closing part of which, in the shut position, is secured by means of at least one bar, which is adjustable from a control mechanism 1 having a spring bolt 15 which is effectively secured in the locking position. The spring bolt 15 comprises two bolt elements 16, 19, which are displaceable one relative to the other and the first 16 of which has locking stop sections 17 which cooperate with a control rower 10, and spring members 22, which endeavour to alienate the two elements 16, 19 in the direction away from the said control rower 10. In a first rotation stage, a lock rower 26 moves the first bolt element 16 into locking engagement so as, upon continued rotation, to move the second bolt element 19 counter to the spring action towards the control rower 10. Upon further rotation, this second bolt element 19 springs back in the direction of the lock rower 26 once the location for its bearing contact against the said second spring bolt element 19 has been passed by the cam top 27, 28 of the lock rower 26, whilst the said first spring bolt element 16 remains in its engagement position. <IMAGE>

Abstract: An arrangement for the non-invasive determination of the minute volume Q of the heart is arranged to determine the amount of a sufficiently soluble gas, e.g. carbon dioxide or nitrous oxide, present in the blood, prior to and subsequent to the passage of the blood through the heart. The expired and inspired gases are separated from one another with each breath taken. Transducers feed respective devices for determining the gas content of the respiration gas, and the magnitude of the expiration gas flow and the inspiration gas flow. These devices are controlled by a microprocessor, which is programmed to supply gas from a gas source, to meter the gas during a subsequent inspiration cycle, and to control an indicator for the Q-value. The gas is controlled in a manner such that the gas-content of the lungs is changed in accordance with a given program. The Q-value is calculated for pairs of respiration cycles in accordance with the formula:  <IMAGE>  in which V1 is the effective gas flow/unit time for a respiration cycle; V2 is the effective gas flow/unit time for the next respiration cycle; Ca1 is the gas content of arterial blood for the first respiration cycle; Ca2 is the gas content of arterial blood for the next respiration cycle. The microprocessor is arranged to calculate Q for a plurality of pairs of respiration cycles (e.g. 5-6 pairs) with a given number of respiration cycles therebetween (e.g. 4), and to send to the indicator a signal corresponding to the mean value of the Q-values obtained.

Abstract: Gassing is significantly reduced in electrochemical cells having anodes of metals, such as zinc, by reducing the number of grains in the particles of the polycrystalline metal to at least a third of the original number of grains and thereafter using the metal in the formation of the cell anode. Such grain number reduction is effected by heat treatment of the anode metal at a temperature below that of the melting point of the metal. Corrosion is further reduced with such reduced grain number particles and particularly with single crystal particles by the addition of small amounts of a gas inhibiting surfactant, for example, an organic phosphate inhibitor such as RA600 from GAF Corp. to the cell. Alternatively, or in addition, corrosion is reduced by prealloying the metal particles with small amounts of one or more of indium, thallium, gallium, bismuth, cadmium, tin and lead prior to reduction of the number of grains or the formation of the single crystal particles. A synergistically lowered rate of corrosion and cell gassing is obtained even with reduction of mercury content.

Date Sep. 20, 1990.The present invention relates to a method for detecting external influence on an optical cable. The invention can be used as a sensor in an intrusion alarm, in which case the cable is buried and an alarm is triggered when someone treads on it. The invention can also be used as a surveillance system for an optical cable transmitting information. The method means that coherent radiation for surveillance purposes is transmitted in multimode in an optical fibre. On the receiver side the surveillance radiation is then split into two beams, that are plane-polarized in two different directions. Then the amplitude and/or frequency content of each beam is detected. A signal which is a measure of their amplitude and/or frequency relation is formed from this. Finally an alarm function is initiated when the signal exceeds predetermined values in time and/or level.
