Title: Needle printing mechanism for mosaic printer - has flexible spring coupling between magnet armature and drive end of printing wire
Inventor: THURNER RICHARD
IPC: B41J2/275
Filed: 1976-07-29
Abstract: Mosaic printer using individual printing wires provides flexible coupling between wire and magnet armature which on the one hand ensures a precise impression without exact adjustment of the armature stroke and on the other hand facilitates large scale release of the wire from the large mass of the armature at the moment of impact. The coupling comprises a spring (5) attached to the magnet armature and holds the drive end of the wire (9) against the armature (4) when the magnet system is inoperative. When the wire strikes the recording surface, however, the elastic coupling permits the wire to lift from the armature. The spring is typically a flat spring (5) or, in the case of a plunger-type armature, a spiral spring.

Title: Tomographic X=ray examination appts. - passes beam through rotating patient onto rotating photographic plate to obtain stack of photographs
Inventor: CRAIG DWIN RICHARDSON
IPC: A61B6/00
Filed: 1976-12-23
Abstract: A method of obtaining an axial tomogram uses a beam of radiation, particularly an X-ray beam which is directed through a slit in a plate, onto e.g. the head of an examined person, while the person is rotated about a vertical axis. This has the effect of varying the absorption of the beam, which is then received by a photographic plate which also rotates about a vertical axis. A series of photographic plates is used, so that a stack of photographs is obtained, giving a radiogram. The rotary speeds are programmed to give a correct exposure. Alternatively, the receiving surface can be a fluorescent screen, onto which the camera is focussed. Further, the position of the examined person can be fixed, and the apparatus rotated around him.
Patent DE-2704800-A1 (DE)
Title: Pneumatic conveyor metering and fluidising system - has fans to blow more air into dispensing vessels when out of use
Inventor: LESK ADOLF
IPC: B65G53/26
Filed: 1977-02-05
Abstract: The metering and fluidising system is for a suction-type pneumatic conveyor where one or more dispensing vessels deliver into a receiver vessel. When the conveyor is in use, the normal quantity of air is blown into each of the dispensing vessels, but when it is shut off or the conveyor fan is stopped this quantity is increased. Where air pressure vessels are used, the opening time of the valve can be short during transport and longer when this ceases. With fans or blowers, suitable valves can be included and controlled to give the same effect. Where the fans have low moments of inertia, the electric motors can be cut in for less than 6 second during transport and out for longer than 4 seconds. On cessation of transport the cut-in time is longer.

Title: Multilayer circuit board with integral flexible appendages - uses array of flexible circuit layers bonded between rigid layers having suitable electrical connections
Inventor: TAYLOR GLEN JAMES
IPC: H05K3/00
Filed: 1977-05-28
Abstract: All the layers are substantially larger than the size the finished circuit board is to be and selectively bonded and slotted in pre-selected locations, and maintained in this over-sized condition throughout the procedure in which holes for interconnections are drilled, and plated through with conductive material. Only after the plating procedure has been completed are the portions of the upper and lower rigid layers removed from locations above and below the appendage portions, thus allowing them to attain the desired, flexible condition. By keeping the rigid layers intact, the assemblage is maintained rigid during the plating, thereby avoiding work hardening of the flexible portions even without tools for restraining the flexible portions.
