Title: Redistribution nozzle for reflux water coolers - with conical slotted plate below orifice, giving improved wetting
Inventor: ILSE WALTER
IPC: F28F25/08
Filed: 1976-06-16
Abstract: A redistribution nozzle for reflux water coolers has a plate fitted below the orifice, this plate having a conical surface and flow passages. The distance between the orifice and the plate is small, and the flow passages are slots, open at the edge of the plate, following secants, in pairs which are parallel to one another but of different lengths. In alternative forms, there is a second plate, below the first, flat or conical, with slots staggered in relation to those in the first, wedge shaped and narrower at the edges of the plates. The plate is carried on one or more rods fixed to a tube which surrounds the nozzle. Alternatively, the support may be a cage, made of several arms, in which the rod carrying the plate fits. The nozzle gives more uniform distribution than existing devices, because wetting takes place not only on an annular surface around the orifice but also in the central circular part. The wetted area is maintained constant in spite of flow variations.

Title: Gas mask with air flow inhibiting visor misting - has capillary material carrying moisture from exhaled air to be picked up by inhaled air stream
Inventor: WARNCKE ERNST
IPC: A62B18/02
Filed: 1976-09-29
Abstract: The gas masks, has the inhaled gas flow controlled in such a way as to prevent misting on the visor. Additionally the moisture retained within the mask is used to humidify the inhaled gas.

Title: Pyrotechnic ballistic thermonuclear implosion system - using explosive charge to compress and heat lithium:7 capsule containing hydrogen
Inventor: STROBEL CHRISTIAN DIPL ING
IPC: G21J1/00
Filed: 1976-10-26
Abstract: A pyrotechnic ballistic thermonuclear implosion system is intended for detonating thermonuclear reactions. An explosive charge is introduced into the tightly sealed in a tapering barrel leading into a cavity contains a tightly sealed striker piston and in the blind end, a lithium-7 capsule contg. an H2 gas or H2 pellet. The charge is fired, causing the piston to strike the capsule and completely compress it and its contents, sealing it into the cavity with its plastic metal. The H2 is thus completely compressed, and the kinetic energy is converted into heat and deformation work, which compacts and heats the Li and the contained gas, heating the Li and the gas to several hundred million degrees. The known reaction of the lithium-7 process takes place above the Lawson coefft., with an ions concn. approaching 1022 cm-3, with a specific heat of the H2 of only 0.01 Kcal/kg/degrees C and specific heat of the lithium of 0.005. A pressure of about 107 bar is reached with a temp. of is approx. 1 Gig-K.

Title: Personal assault alarm network - is triggered by irregular breathing and detected by transducers concealed inside clothing
Inventor: ILLGUTH GUSTAV
IPC: G08B13/00
Filed: 1976-10-29
Abstract: The personal alarm network is triggered by irregular breathing detected by a transducer concealed in the clothing of the protected person os that if he breathes deliberately in an irregular manner and if he is in some defined area, typically a bank, or near a protected vehicle, an alarm in that area is triggered. The appts. uses elastic clothing or elastic bands worn by the person concerned, round his chest, so that transducers in this clothing or bands, detect any deliberate irregularity in his breathing, trigger a protable transmitter carried by the individual concerned, and thus trigger a remote alarm. Various measures to prevent false alarms are available.

Title: Synchromesh gearbox for heavy vehicle - has dog clutch sleeve comprising two mirror image parts with slot between
Inventor: ERNST ROLF
IPC: F16D23/06
Filed: 1977-06-03
Abstract: The synchromesh is for motor vehicle gearboxes, particularly on lorries, coupling loose gears with shafts by sliding dog clutches, whose movement into the finally-engaged position is prevented by baulk members moved into position by synchronising rings having cone faces working with mating faces on the other components. The rings are rigidly secured together by axial bolts to form assemblies sliding in relation to the dog clutch and rotating in relation to it for a limited amount. Baulk segments are evenly spaces round the periphery, the bolts passing through them without clearance, and have ramp faces working with the baulk members. The dog clutch sleeve (17) is formed by two similar mirror-image parts fitted together to form a slot (24) between at right angles to the axis accommodating the segments (25). The latter have pairs of ramp faces on the inside, working with balls forming the baulk members.
