Title: Detecting coolant circuit leaks in an electrical machine
IPC: G01M3/20
Filed: 1978-11-21
Abstract: Leakages in electrical machine windings (3) which are coolant-cooled at least in the stator, are determined by moisture measurement within a closed machine housing (1), in which a cooling gas flow cooled by recooling units (8) is additionally circulated. To produce and maintain a normally stationary moisture state in the gas flow within the machine housing (1), the dew point is fixed by a special heat sink (20, 21) in the region of the cooling gas flow, and then any moisture changes deviating from the stationary state are measured to indicate leakages. In order to distinguish between leakages in the windings (3) and other leakages such as in the units (8), an easily detectable indicator is added to the coolant for the windings (3), and the condensate formed in the heat sink (20,21) is monitored for the possible presence of this indicator. A moisture measuring unit 27 in a gas by pass circuit 26 provides information regarding any leak in either of the two coolant circuits through windings 3 and units 8.   <IMAGE>

Patent GB-2024492-A (GB)
Title: Fast Rewind of Tape in Recording and/or Playback Apparatus
IPC: G11B15/44
Filed: 1979-06-25
Abstract: When a manual actuator S4 moves between "normal" and "fast rewind" positions, in addition to lifting the pressure roller from the capstan, it briefly earths a monostable multivibrator 3 and hence causes a pulse to be delivered to relay R1 which reverses the direction of tape motion. When moving between "normal" and "fast forward" the line 2A is not earthed. Closing switch S3 also reverses the direction of tape movement. Automatic reversal of tape movement at each end of the tape is described also: a detector 1 senses the motion or otherwise of tape reel support 20 and hence causes a pulse to be delivered to the reversing relay R1 through logic break 2. <IMAGE>

Title: Cache storage systems
IPC: G06F12/126
Filed: 1979-11-07
Abstract: A cache unit includes a cache store organized into a number of levels to provide a fast access to instructions and data words. Directory circuits, associated with the a cache store, contain address information identifying those instructions and data words stored in the cache store. The cache unit has at least one instruction register for storing address and level signals for specifying the location of the next instruction to be fetched and transferred to the processing unit. Replacement circuits are included which, during normal operation, assign cache locations sequentially for replacing old information with new information. The cache unit further includes apparatus operative in response to a first predetermined type of command specifying the fetching of data words to set an indicator flag to a predetermined state. The apparatus conditions the replacement circuits in response to each subsequent predetermined type of command to bypass storage of the subsequently fetched data words when the indicator flag is in the predetermined state preventing the replacement of extensive numbers of data and instruction words already stored in the cache during the execution of the instruction. The cache unit further includes detection apparatus for detecting a conflict condition resulting in an improper assignment. The detection apparatus, upon detecting such a condition, advances the replacement circuits forward for assigning the next sequential group of locations or level inhibiting it from making its normal location assignment. It also inhibits the directory circuits from wiring the necessary information therein required for making the location assignment and prevents the information which produced the conflict from being written into cache store when received from memory.

Title: Handling fine dusts without pollution
IPC: C08K11/00
Filed: 1979-12-21
Abstract: Fine metallurgical dusts, possibly toxic, are separated from air in a venturi scrubber or in a dry filter from which they are discharged into water. The resulting water-dust mixtures are filtered to produce cake, which is bonded by adhesive such as glue, sulphite lye, lignosulphate compounds or polyvinyl acetate. The adhesive is either mixed with the water used in the scrubber or on the discharge side of the dry filter or alternatively is pumped through the filter after the filtration stage. The resulting cake is discharged from the filter and formed into flat slabs, which are then heated to harden their surfaces sufficiently to allow mechanical handling.

Title: Cathodic protection joint for use with piles
IPC: C23F13/02
Filed: 1980-03-03
Abstract: The joint comprises two metal joint parts (16, 18) which are connectible together, such as by connecting elements (28) in abutting relationship. Each joint includes at least one protective member e.g. a skirt (29) disposed at or adjacent the periphery of at least one of the joint parts and electrically connected thereto. The protective member is made of a metal e.g. Zn, Al, Mg which possesses a higher electro-negative potential than the metal portions of the joint parts to be protected. Thus, when the joint is buried in damp ground or immersed in a liquid the protective member constitutes a sacrificial anode of an electrolytic circuit in which the joint constitutes the cathode and moisture in the ground or the liquid in which the pile is immersed constitutes the electrolyte, thereby protecting the joint from corrosion. <IMAGE>
