Title: Stylo nib cleaning wire - is of different geometrical shape to cross section of nib bore
Inventor: KUPARINEN LASSE
IPC: B43K1/10
Filed: 1973-10-19
Abstract: The wire is connected to a drop weight and can move for a limited amount in both the axial and the radial direction, its forward end bearing against the drawing paper. The geometrical shape of the wire section is different from that of the cross-section of the nib central bore in which it is accommodated. Typically it can be square or polygonal, with, in the former case, the edges chamfered. An even division of Indian ink along the width of the lines assured and the drawing speed is increased. The difference between the cross sections ensures that the cleaning wire does not lead on a relatively long bowed area of the inner wall of the middle bore, so that no ink giving section, while writing, or drawing is significantly reduced in size.

Title: Catalytic cleaner for IC engine exhaust gases - has external catalyst container connected to exhaust manifold
Inventor: SCHISCHKOW KONSTANTIN F
IPC: F01N3/20
Filed: 1974-02-15
Abstract: Catalyst is held in powder form in a container which is attached in a suitable position to the engine frame. A connection is taken from the upper part of the container to a point in the exhaust manifold. The container is vibrated by the engine or by separate means and the vibrations together with the fluctuating exhaust gas pressure cause powder to flow into the manifold where it promotes after-burning of exhaust gas impurities. A valve in the connection prevents solid impurities entering the catalyst container. A second pipe entering the bottom of the container is connected to a pressurised source of gas which may be the exhaust pipe. The arrangement enables a simple catalyst system to be added to existing engines.

Title: Hobbing grinder for straight fluted bevel gears - has grinding disc and link support having rectangular openings in its front and rear
Inventor: KEDRINSKY WASILY NIKOLAEWITSCH
IPC: B23F15/06
Filed: 1974-03-04
Abstract: L-shaped guide elements are mounted in the rectangular openings in the link holder and are used to align a support in the holder. This support carries the spindle with the grinding disc and is set into oscillatory motion by a drive unit mechanically coupled to it. One of the surfaces of each guide element rests on the front and rear sides of the holder while the other surface rests on the upper and lower surfaces of their openings. The gap between support and guide elements can be regulated because the upper surfaces of the openings and the associated surface of the guide element are inclined. The design of the support and holder creates a machine with an increased rigidity as compared with conventional machines.
