Inventor: ISSHIKI ISAO
IPC: G06V10/24
Filed: 1980-04-02
Abstract: A circuit (3) is adapted to binary-code analog signals which are read by a two-dimensional sensor comprising photo-electric conversion elements arranged in two-dimensional manner. In the cells of the photo-electric conversion elements arranged two-dimensionally, a cell which has detected black is called 'a black cell'. Then, the output of the binary coding circuit is applied to a column black cell detecting circuit (13) senses the presence of black cells in each column (in a vertical direction) and to a temporary storing buffer memory (14) operating to temporarily store white/black patterns. The column black cell detecting circuit outputs a left end black cell detection signal (15) representative of the detection of black cells in the left most column. A left side character element detection signal (16) is representative of the fact that black cells are continuously present in several lines on the left side except for the left most column. A right side character element detection signal is also produced (17) when black cells are continuously present in several lines on the right side except for the right most column, and a right end black cell detection signal (18) representative of the detection of black cells in the right most column.

Title: Quick release for vacuum circuit breaker - has low inertia mechanism mounted directly on live pole
Inventor: GROSSMANN FRANZ KARL DIPL ING
IPC: H01H33/666
Filed: 1980-05-31
Abstract: The trip mechanism for a vacuum circuit breaker enables a quick normal tripping action as well as a quick trip immediately following circuit breaker closure. The latter condition is representative of closing the breaker onto a fault. The increase in speed is achieved by reducing the mass, and hence the inertia, of the release mechanism. The desired reduction in mass is achieved by mounting the release mechanism directly on one pole of the circuit breaker, at high potential. A lever operated by a boss on the contact operating bolt sets the latch when the circuit breaker is closed. At the same time the connected rod and spring system engages the lock which holds the contacts closed. To initiate a trip the latch is released. The springs rapidly move the light rod such that the attached lever turns the bolt to the free position allowing the trip springs to part the contacts.

Title: Device for scattering chipboard disperse material on a mould belt
IPC: B27N3/14
Filed: 1981-03-11
Abstract: The invention starts from a device for scattering chipboard disperse material on a moving mould belt in the course of producing chipboards and the like. The device includes a disperse-material hopper, a hopper discharge apparatus, a disperse-material ejector and a distribution head. The distribution head has two distribution rolls rotating in opposite directions and connected transfer apparatuses. The distribution rolls form, between themselves, a charging throat. A scattering head is connected to each transfer apparatus, which scattering heads operate above the mould belt. To ensure that, using a device of this kind, a disperse-material cake can be achieved on the mould belt, which disperse-material cake is built up symmetrically or unsymmetrically with respect to the cake centre-plane, with a predetermined, defined structure, a uniform-distribution shaft is arranged between the disperse-material ejector and distribution rolls, which is movable back and forth orthogonally to the charging throat, at least at its lower end, allocated to the distribution rolls. In this manner pronounced segregations which have occurred as early as in the disperse-material hopper, in the hopper discharge apparatus or during disperse-material ejection can be compensated by even distribution of the disperse-material stream on both sides of the charging throat. <IMAGE>

Patent DE-3113123-A1 (DE)
Title: Contact-spring attachment in built-in parts
Inventor: SEEGER GUNTER A ING GRAD
IPC: H01R13/40
Filed: 1981-03-27
Abstract: Contact springs in plug sockets and the like are normally plugged through a slot in a carrier board, and the so-called contact tongue emerging on the other side of the carrier board is, in the simplest case, somewhat twisted in order to prevent the contact spring, between whose correspondingly bent ends a plug pin engages, being dragged along when the plug pin is pulled out. The intention of the invention is to support such a contact spring on both sides of the carrier board or base board, on this base board, such that said base board is securely locked in both possible movement directions. This is achieved by the invention in that the contact spring is provided with one or more upper stops and the contact spring is inserted into the slot in a base board as far as these stops, while the soldering tab which projects from the underneath of the base board has a further stop which does not become effective until the soldering tab has been plugged through. The elements for additional locking can be manufactured without any difficulties and with very low additional costs in the context of mass production.

Title: Anti-skid protection and tyre blow-out safety device for motor vehicles
Inventor: SCHUSTER FRIEDRICH
IPC: B60B39/00
Filed: 1981-06-12
Abstract: Anti-skid protection for motor vehicles is intended to prevent lateral skidding of the moving vehicles in the presence of slush and ice. Anti-skid protection consists of a disc which is secured to an arm on the inside of the vehicle wheels in such a way that it can be lowered by the driver by means of a lever when there is a risk of skidding. A disc is attached to each car tyre and a slight pressure is exerted on the disc by a steel spring so that said disc is constantly in contact with the surface of the road. The disc rolls next to the car tyre and, exclusively when lateral skidding of the tyre occurs, makes a cut into the slippery surface and thus prevents further lateral skidding of the vehicle. Anti-skid protection can also be used as a tyre blow-out safety device in that it is secured in the direct vicinity of the surface of the road so that, in the event of a tyre blow-out occurring, the vehicle can continue to roll on the disc without leaving the lane.
