Title: Output stage of heart-pacemaker - reduces decay time of stimulus voltage and allows use of adaptive pacemaker
Inventor: REHAK JAROSLAV DIPL ING
IPC: A61N1/362
Filed: 1975-05-09
Abstract: A heart pacemaker of the usual kind provides a stimulus pulse, which initiates not only a heart cycle but also an interval during which the input circuits of electrocardiographs which use the same electrode within the heart, are overloaded, and their outputs accordingly cease to communicate meaning. In particular, this interval (250-300 ms) is too long to permit the use of the adaptive pacemaker, which responds to the momentary state of the heart muscle, and cannot do without information about it for so long. A control circuit is included in the output stage of the usual simpler pacemaker, with the effect of reducing the blacked-out interval to about 40 ms.

Title: Pressure cooker safety lock - has swivel balance moving in both directions to ensure perfect engagement
Inventor: NITSCHKE GEORG
IPC: A47J27/092
Filed: 1975-11-21
Abstract: The pressure cooker safety lock comprises a bayonet engagement between the pan (11) and lid (15) which is closed by a seal which if the bayonet engagement is not complete is raised from the sealing surface by means of one arm of a balance (17). The balance (17) has two lift arms (20, 21) which are mounted symmetrically to the actuating arm (19) which projects into the path of movement which is followed by the actuating peripheral segment (12) of the pan during opening and closing. The actuating arm (19) and the two end edges (13, 14) of the actuating segment (12) are arranged so that the two end edges swivel the actuating arm in opposite swivel directions, and thus the effectiveness of the lock does not depend on swivelling the lid in one direction relative to the pan.

Title: Neutralisation of static charge on electrophotographic ribbon
Inventor: BACON JAMES LYDELL
IPC: B65H9/00
Filed: 1976-09-03
Abstract: Neutralisation of the static electric charge built up on paper or plastics material forming leaves or ribbons is performed during electrophotographic copying etc. The charge built up is that caused by the movement of the material during its processing, causing the adhesion of the leaves to each other. The individual leaves are passed on insulating rollers, supported by an air film or by a series of wires through a spaced group of up to four air ionizing points. Each such point or station provides alternate negation of positive and negative charge build up. The stations are positioned such that during the polarity cycle the leaf section is appropriately treated.
