Title: Battery-powered brake light for bicycle - has switch activated by reverse movement of chain of fixed wheel bicycle
Inventor: BUCHHOLZ CLAUS
IPC: B62J6/16
Filed: 1990-09-20
Abstract: The bicycle lighting system includes a large area rear light (1.1) operated from a battery. The brake switch (1, 2) is mounted above the lower section of the chain and is operated when the chain moves backwads. The machine is braked by reverse pressure on the pedals.

Patent DE-4038183-A1 (DE)
Inventor: SERMUND GERALD DR
IPC: B41C1/05
Filed: 1990-11-30
Abstract: In the process for directing an electron beam relatively to a usefully engraved reference object taking the form of a substantially cylindrical roller, the roller is first given a set of recesses forming a reference marking system in the peripheral direction by electron beam bombardment. Then at least part of the useful engraving is produced in an exact position relatively to the reference marking. After an interruption in the electron beam bombardment, the reference marking is detected during a measuring operation by the electron beam by scanning in the longitudinal direction of the roller and then a reference point is found by scanning the circumferential direction of the roller. The recesses forming the reference marking are arranged in a circumferential region extending over only a part of the circumference of the roller. Once the position of the reference marking has been found in the longitudinal direction of the roller, a position analysis is made during several measuring cycles of predeterminable duration within a measuring window by the relative assessment of measuring signal amplitudes allocated to successive measuring cycles.

Title: Mfr. of locally reinforced aluminium alloy composite material - by mixing silicon carbide whiskers with alloy powder, sintering then partially coating with thin aluminium film etc.
Inventor: ODA TAKASHI
IPC: C22C47/14
Filed: 1991-04-18
Abstract: Al alloy composite material is produced by mixing SiC whiskers (10-50 microns dia. 0.1-5 microns and length 30-100 microns) and Al alloy powder and sintering to give a starting material. This is then partially coated with a thin Al film (min. purity 99%) some 0.5-20 microns thick by preheating the material to 20-100 deg.C below the solidus temp., then heating the matrix Al alloy 50 deg.C above its liquidus temp. Prod. is then placed in a mould and cast at a pressure of 250-3000 kg/cm2. USE/ADVANTAGE - For the internal combustion engine items, e.g. pistons, avoids problems associated with othr reinforcing systems, e.g. Al2O3 surface films gives good bond strength between matrix material and reinforcer. In an example, Al alloy powder (250 mesh size or less) was dispersed in water along with SiC whiskers (0.5 microns dia. and average length 20 microns), then filtered and dried to give a whisker content of 15%. This was heated to 600 deg.C and 5 x 10 power (-5) torr vacuum and sintered at a pressure of 100 kg/cm2 and press time of 20 minutes to give a slide shape starting piece of 50mm thickness and 80 mm dia. Slide was cut in half to give a semi-circle and Al foil (99% pure and 1 microns thick was applied to its surface in vacuo. This was then preheated in Ar at 500 deg.C, and the molten matrix material (Al alloy AC8A, same as starting powder) at 700 deg.C was poured in and pressure cast at 500 kg/cm2. A test piece of the part reinforced item showed a good tensile strength (35 Kgf/mm2).

Abstract: There is a stroke control device, in which a pushing rod 3, 4 which presses a moulded block 6 of a layer 5 is provided, the stack gripper head 13 can reciprocate while being guided by a stroke drive 16, one layer of moulded blocks 6 is placed on the other for stacking and the downward stroke of the stack gripper head 13 is reduced by the thickness of one layer each time a layer is laid. It is desirable for there to be measurement of the actual stack height which is independent of the movement of the stack gripper head. This is achieved in that a computer 10 adds up the successive layer thicknesses to obtain the stack height in each case and, for each layer 5 to be laid, controls a height setting of the stack gripper head 13 in accordance with the total stack height, and in that a path-measuring device 7, 8 which is assigned to the pressure-exerting pushing rod 4, 5 for measurement of the layer thickness in each case is provided and feeding 11 of the measured layer thicknesses to the computer 10 is provided, so that the total stack height is measured. On the basis of the measured thickness, the computer determines the actual height of each stack, and this height is used to determine the target position of the stack gripper head.

Abstract: A brake pressure regulating device has a brake pressure sender unit (1, 19, 20) connected to a brake (VL, VR, HL, HR) via a pressure line (6, 7, 12, 13). A pressure-controlled inlet valve (14) in the pressure line (6, 7, 12, 13) connects the brake pressure sender unit (1, 19, 20) to the brakes (HL, HR) without throttling in a first operating position and via a throttle diaphragm (49) in a second operating position. The inlet valve (14) has a piston (35) which is acted on in one direction by the pressure in the pressure line (6, 7, 12, 13, 28) and in the opposite direction by a spring (38) and by the pressure in a return line (15, 44). The return line (15, 44) contains an outlet valve (16) controlled by a regulating device. In its rest position, the outlet valve (16) shuts off the return line (15, 17, 18) and in its operating position frees the return line (15, 17, 18). The inlet valve (14) has a valve element (39) which co-operates with the piston (35). In the second operating position, the valve element (39) shuts off the pressure line (12, 13) and frees a valve seat (37) formed by a longitudinal bore (36) in the piston (35) through which the brake pressure receiver (HL, HR) can be connected to the return line (15, 17, 18).
