Title: Jamming of laser range finder from aircraft - employs expanded jamming laser beam automatically orientated towards range finder
IPC: H04K3/00
Filed: 1976-03-30
Abstract: Problems of generating decoys or false codes for laser range finders used for locating aircraft in flight are released by a laser jamming system. This system is of low weight permitting it to be carried on an aircraft. Laser emissions are received by omnidirectional detectors at the extremities of an aircraft. Electronic circuits determine difference in time of arrival of the same laser pulse to determine its orientation. These circuits initiate an expanded jamming laser beam which is orientated towards the emissions. A collimator and convergent lens expand the jamming beam which is orientated by a plane mirror (10) mounted on a rotatable suspension shaft (11).

Title: Large feed water preheater for nuclear power plant - has integral steam expansion chamber to save space
Inventor: ARNESSON OLLE
IPC: F22D1/32
Filed: 1976-06-30
Abstract: A feed-water preheater for a nuclear power plant is located between feed pump and reactor and is of the vertical type, with the water flowing through the tubes and steam of different pressures, from various parts of the plant, flowing around the tubes. The lower part of the preheater casing is an expansion vessel for that portion of the steam which is at a higher pressure than the remainder. Pref. a screen plate separates moisture from expanding steam coming from a high pressure source and collects condensate from the water tubes (17) above. The condensate leaves the vessel at the bottom (8;10). Used for the large feed-water preheaters required in a nuclear power plant. The arrangement shown saves considerably space and expense by comparison with a system where the expansion vessel is separate from the preheater.

Title: Attenuation of slotted waveguide aerial parasitic side lobes - is achieved by plate filter installed in plane of emission
IPC: H01Q13/02
Filed: 1977-05-05
Abstract: An attenuator is used to get rid of parasitic side lobes caused by interference in the output of slotted waveguides. The slots are alternated about the lengthways axis of symmetry of the guide. Attenuation is achieved by the use of a resistive filter (24) supported by end struts (25) from the slotted face of the waveguide. The plane of the filter is parallel to that of the short guide wall (21) and is positioned at least lambda o/4 away from the slotted face along the axis of symmetry (x-x'), where lambda o is the aerial operating wavelength. The filter plate having a depth of lambda o/2 may be laminated, the resistive component being a ferrite or some material having similar dielectric and resistive properties.

Title: Heat transfer printing of garment cut=out patterns - for the making=up of dresses of shirts
IPC: A41H3/08
Filed: 1977-05-06
Abstract: In the making up of dresses or shirts, a length of fabric is printed by heat transfer with the repeat pattern for the body of the garment on the greater part of the width of the piece, and further, with a succession of outlines for the garment trimmings at the selvedge. The body pieces and the trimmings are then cut out from the appropriate parts of the fabric.
