Title: Improvements in electrical leakage control apparatus for electro chemical machine tools
IPC: B23H3/00
Filed: 1980-09-12
Abstract: In an electro chemical machine tool 10 has a rotary disc 50 fitted to its support structure, so as to intercept electrolyte and throw it off in dispersed droplets so as to break the electrical path and so obviate risk of shocking the operator, an air operated reaction turbine 62 rotates the disc 50 and plates 64 fixed to the turbine act as air brakes and prevent overspeeding. The choice of a reaction turbine obviates the corrosion problems due to the electrolyte laden atmosphere experienced when driving the disc by electric motor and belt. <IMAGE>

Title: Two-dimensional interpolation of spatial and shading corrections to tv image
IPC: H04N5/16
Filed: 1981-04-13
Abstract: Data for providing spatial and shading correction signals, particularly in a TV camera, are taken from a two dimensional array of error measurements distributed across a television image and stored as 8 bit words. The correction waveforms are interpolated linearly inside rectangles of neighbouring data points. A vertical interpolation circuit 12 provides a sequence of points on each video line by adding at 58 for each column signals produced by a multiplying D/A converter 38 when loaded with the two values to be interpolated and weighted by factors related to the distance of the line from each row. The results are fed to a horizontal interpolation circuit 14 which ramps linearly from one point in the sequence to the next, to provide the video correction output signals. <IMAGE>

IPC: B60G/
Filed: 1980-10-27
Abstract: An axle suspension system wherein shock-absorbing members (31, 32) allow vertical movement of an axle (25) relative to a frame (16).

Title: Lock device
Inventor: KONTKANEN JOUKO
IPC: E05B9/04
Filed: 1983-03-28
Abstract: A lock device comprises a door lock 1 and a cylinder lock mechanism 2 attachable thereto for transmitting operating force from a key operating said cylinder lock mechanism to said door lock via a turnable force transmission member 4 connecting said cylinder lock mechanism to said door lock. The device includes means allowing adjustment of the distance between the cylinder lock mechanism and the door lock. One or several detachable extension members 7 enclosing the force transmission member form an extension of the outer housing 3 of the cylinder lock mechanism in a direction towards the door lock. The dimension in this direction of each extension member is a small part of the length of the force transmission member, which length is reducible to a value suitable for the actual mounting distance between the cylinder lock mechanism and the door lock. For the adjustment of the attachment of the cylinder lock mechanism to the door lock as well as for the protection of the force transmission member over its total length, a required number of said extension members 7 are mounted between the cylinder lock mechanism and the door lock. <IMAGE>

Title: Agricultural cultivator
Inventor: RIACH ALAN
IPC: A01B61/04
Filed: 1983-07-26
Abstract: A mounting element 12 supports a share 11 relative to a frame 10 for mounting on or towing behind a tractor. A first part 13 of the mounting element 12 carries the share 11 by way of a flat vertical tine 14 and is connected to brackets 21 on the frame 10 by a ball joint 20. A second part 16 of the mounting element has a cross-piece 17 which abuts against the underside of the frame 10. In the event that the share 11 encounters a minor obstruction in use, the mounting element 12 will pivot selectively about two axes (22, Figure 3, not shown), each of which passes through the balljoint 20 and a respective end of the cross-piece 17, so that the share may avoid the obstruction. If however a major obstruction is met, a shear pin 19 between the parts 13 and 16 will fail, to permit the share 11 to pivot rearwardly (see Figures 5a, 5b, not shown). A latch 23 is arranged to engage a guide 24 on the frame 10 to prevent the share 11 subsequently from swinging sufficiently far forwardly that the tyres of the tractor may be damaged. <IMAGE>

Title: Low power consumption electronic circuit
Inventor: YAMASHIRO OSAMU
IPC: G04C10/00
Filed: 1983-10-12
Abstract: According to the present invention, the voltage of a battery is supplied to an electronic circuit such as a watch circuit through a step down circuit which is constructed of capacitors and switching MIDFETs. The step down circuit performs a current converting operation as well as a voltage converting operation. The operating current of the electronic circuit is reduced by the reduction in the operating voltage of the same. As a result that the operating current level of the electronic circuit is dropped and that the current conversion is performed by the step down circuit, the battery current is relatively largely dropped. The construction thus far described elongates the lifetime of the battery. According to the present invention, therefore, there is provided a circuit which is proper for driving the step down circuit.
