Abstract: 1305226 Railway airline couplings GERMANY MINISTRY OF TRANSPORT 9 Feb 1970 6043/70 Addition to 1287155 Heading B7T [Also in Division F2] In the airline coupling between railway stock having an automatic central buffer, coupling and railway stock having a conventional drawhook screw coupling (as disclosed in Specification 1,287,155), the airlines of the automatic central buffer coupling are telescopic so as to be able to move out to butt against the airline coupling 1 associated with the drawhook screw coupling, and the latter coupling support 2 is provided with a bracing member 16. Laterally swingable cover flaps are also provided on the automatic coupling, said flaps moving to cover the airline mouthpieces subsequent to an uncoupling operation, and the bracing member 16 extends laterally from said support 2 so as to be engageable by the cover flap device 18 during uncoupling so as to assist the separation of the airline coupling members. The end of the bracing member 16 is arranged so as to engage a surface 17 of the automatic coupling 9 when in the coupled position to assist retention of the coupling member 1. A part 16a of the bracing member 16 is arranged to face towards the housing of the airline coupling of the automatic central buffer coupling and to lie to one side of the associated airline mouthpieces when in the coupled position. This portion 16a moves laterally across the ends of said associated airline mouthpieces during a coupling up operation and thereby prevents the telescopic airlines from premature extension and possible damage.

Abstract: 1313137 Alarm systems EMI Ltd 8 July 1970 [10 May 1969] 23915/69 Heading G4N In an acoustic or supersonic intruder or fire alarm system, the transmitter 2 is coupled to the receiver 5 partly via a channel 4 shielded from atmospheric disturbances, receiver 5 being responsive to the phase of the received signal. As described, a piezo-electric transducer 2 is energized by a 300 kHz oscillator 1 and is partly coupled to the receiver 5 by means of a hollow semi-cylindrical glass enclosure 4. Any change in temperature or movement of the atmosphere outside channel 4 will cause a differential phase variation at the receiver 5 resulting in an alarm. A heat source 7 may be included to improve the sensitivity. The system may also be responsive to the body heat of an intruder. In Fig. 2 (not shown) channel 4 may comprise a tube passing through a boundary wall of an enclosed building. Entry to the building will cause a piston of air to flow through the channel and so give rise to a Doppler phase shift at the receiver 5.

Title: Method of fabricating multilayer circuits

Filed: 1971-12-08
Abstract: 1321545 Printed circuits INTERNATIONAL BUSINESS MACHINES CORP 8 Dec 1971 56900/71 Heading H1R A method of manufacturing a multilayer ceramic circuit board comprising the steps of forming simultaneously a predetermined pattern of through holes and channels in a green ceramic sheet by exposure to radiation through a mask, laminating several of said sheets, each sheet having an individual predetermined pattern, and filling the resultant holes and channels with a molten conductor to complete the circuit pattern. Green ceramic sheets, in which, due to the subsequent sintering process, the basic constituent oxides contained in the materials must not be too easily reduced to the elemental state, are formed from a ceramic organic slurry and covered with a photolith or molybdenum mask having the desired hole and line patterns. Through holes and channels are formed simultaneously on exposure to radiation from a CO 2  laser, the green sheet being volatilized at a rate depending upon the size of the apertures in the mask, the larger the aperture the larger the amount of material volatilized and therefore the deeper the cut. Several ceramic sheets 30-32, Fig. 3B, having individual hole and channel patterns are then placed in a registration platen such that the circuit patterns 33-37 are in correct alignment and the structure is then heated under pressure to form a unitary body. The body is then sintered in order to burn off any binder material in the ceramic and to render the ceramic more dense. Metallization of the channels and through holes is then carried out by drawing molten copper from one side of the circuit board through the holes and channels by means of a vacuum applied at the other side of the circuit board. Alternatively a capillary fill process may be used.
