Patent DE-3817057-A1 (DE)
Title: Method for the manufacture of a single-layer sensor coil
Inventor: DOBLER KLAUS DIPL ING DR
IPC: H01F41/04
Filed: 1988-05-19
Abstract: In a method for the manufacture of single-layer sensor coils, a layer (11) made of metallic material is deposited on a substrate (10) made of electrical insulating material. With the aid of a sharp tool, in particular a lathe cutter, a thread (11) is turned in the layer (11) to a depth such that an electrically conducting zone and an electrically non-conducting zone, running next to one another in each case, are formed. It is particularly easy to manufacture a sensor coil arranged on the inner wall of the substrate (10). It is thereby possible to reduce the distance between a plunger core and the sensor coil. <IMAGE>

Title: Apparatus for producing a flavoured string of smoking material
Inventor: LETTAU KLAUS-DIETER
IPC: A24C5/18
Filed: 1988-06-28
Abstract: In the production of cigarettes it is known to spray a menthol-containing liquid onto a layer of tobacco which has been deposited on a conveyor in the area of a deposition stretch. The spraying is carried out using compressed air. When the cigarettes are subsequently wrapped with cigarette paper, there is a risk of flecks forming on the cigarette paper. In the method according to the invention, the flavoured liquid is introduced into the tobacco in the area of the deposition stretch (AS) at a point where approximately half of the final tobacco layer has been deposited. The second half is thereafter deposited, so that the liquid is situated inside the finished tobacco layer (15). The liquid is sprayed into the tobacco without the use of compressed air, as a result of which crystal formations are avoided. The rate of injection of the liquid is controlled as a function of the operating speed of the cigarette machine. <IMAGE>

Patent DE-3910803-A1 (DE)
Title: High-speed output buffer
Inventor: ZIERK JONATHAN C
IPC: G11C11/409
Filed: 1989-04-04
Abstract: A high-speed output buffer for a memory chip includes an output line, to which a high or low voltage is applied, to represent a logical "1" or "0" as the output data during an output interval. Immediately before the next output interval, the line is pre-balanced to a voltage half-way between the high and low voltage level. In this way, the system achieves high-speed full logic jumps on the output line, with less noise and a lower rising rate during the output interval. The pre-balancing technique, and the arrangement of the pre-balancing circuits near to the output pin on the chip, minimise the danger for the memory core resulting from power supply risks.

Title: Powered circular hand-saw - has pivoted blade assembly allowing in-cut adjustment of depth of cut by twisting hand grip
Inventor: STOLL KURT DIPL ING
IPC: B27B9/02
Filed: 1989-06-16
Abstract: The powered circular handsaw has a housing (10) and guard which enclose the blade (1) except for the working aperture.  The blade and electrical drive assembly are pivoted relative to the housing about the axis (33) so that the blade can be lowered through the bottom plate (21) to the required depth of cut. This is done by rotating the disk (37, 30), which causes the pin (38) to move in slot (39) and force the blade and drive assembly downwards against the spring (44). The shaft of the disk (37, 30) extends through the housing and forms part of an adjusting twist grip which also serves as the principal hand grip for guiding the saw in the cut. USE/ADVANTAGE - High safety in operation of depth of cut is easily and positively adjustable during cutting.

Title: Can filling machine with rotating conveyor - holds can at angle inclined to vertical to counteract centrifugal force
Inventor: HOLZMANN KLAUS
IPC: B65B43/60
Filed: 1989-08-24
Abstract: Containers such as cylindrical cans are filled with a liq. from a rotating circular tank 83). The cans (2) are brought to the filling station by a conveyor (17) and then transferred to the filler conveyor (1) which rotates with the tank (3). The centrifugal force imposed on the cane by the rotation of the conveyor (1) causes the surface of the liq. in each can to be inclined to the horizontal. To counteract this effect the cans are supported on the circular conveyor with their axes inclined to the vertical so that the surface of the liq. in the can is at right angles to the can axis. USE - Canning.
