Inventor: VOGEL OTTO
IPC: E01H11/00
Filed: 1991-06-29
Abstract: The proposal is for a process for de-icing roadways to which is applied a melting agent to lower the freezing point. In order to save melting agent (salt), the melt water running off the roadway is collected and re-used for de-icing purposes provided that its melting agent content is adequate. To implement the process, use is made of a device for de-icing roadways including, along the length of the roadway, components such as spray nozzles (34) to apply the melting agent and run-off channels (16) to divert the water into a drainage channel (18) connected to a collector channel in its cycle. According to the invention, the run-off channels (16) lead into at least one collector tank (20) which returns the adequately concentrated melt water to the spray nozzles (34) via a supply line (26).

Title: Clutch and brake unit - utilises electromagnetism to release the drive to yarn feed drum and applies the brake simultaneously
Inventor: HUEFNER JUERGEN DIPL ING
IPC: D04B15/48
Filed: 1991-07-05
Abstract: A combined clutch and brake unit provides selection of a coupled rotary drive or de-clutch with brake applied. The clutch has a housing surrounding the drive shaft. It rotates with the drive shaft, and slides to uncouple the driven part. It incorporates a magnetic core. The outer brake mechanism slides, but does not rotate. When the clutch releases the drive to the driven part the brake mechanism subsequently applies a pad to the friction plate of the driven part, to stop rotation. Pref. the centre shaft (31) is driven by the machine belt. It is mounted in a bearing (33) on the framework, and in two bearings (36) in the yarn feed drum (35). A housing (46) contains a winding (76) for the electromagent. The electromagnetic core (39) inside the housing is attached to the centre-shaft (31) with a groove and sliding piece (43,44). The spring (59) in the bores (60) in the core (39) press down the clutch pad (40) which consists of soft iron magnetic material. When current is applied to the winding (76) the core (39) attracts the clutch pad (40) releasing it from the friction plate (58) on the drum (35). The drum now rotates freely on the bearings (36). The continued supply of current to the electro-magnet closes a large gap at the top of the core and the ring (52). The outer circumference (49) forming the braking mechanism, is also electro-magnetic material, (50) to complete the magnetic circuit. The brake (49) slides to press the brake pad (51) against the friction plate (58) on the driven part (35) to stop the rotation. USE - The combined unit is attached to the yarn feed on a knitting machine, where the pattern demands a sudden stop and start, with even tension of yarn.

Title: Tool for fixing threaded bushes in thin sheet from one side - has forming finger which is passed through bush bore and then forced radially outwards and rotated to produce retaining flange
IPC: B23P19/06
Filed: 1991-09-23
Abstract: The threaded bush (50) has a short, thin-walled section (52) of reduced diameter at one end which locates in a hole in the sheet (60). To secure the bush in the sheet the spindle (4) of the tool is introduced through the bore of the bush. Axial pressure on the tool causes a forming finger (3) to pivot radially outwards from a slot (21) in the spindle so that the tip (30) presses on the thin-walled section (52). As the tool is rotated the section is turned over to produce a retaining flange. The tool spindle (4) and upper part of a telescopic housing are clamped in a drill spindle. The lower part of the housing which is keyed to rotate with the upper part, carries a thrust bearing (24) and an adjustable pivot for the forming finger (3). When the upper part of the housing is forced downwards against the pressure of pre-loaded springs a pin bears on a lever extension of the finger and causes it to pivot radially outwards. USE/ADVANTAGE - Bush can be secured solely by access from one side.

IPC: F16B15/02
Filed: 1991-12-02
Abstract: Nails are driven into hard receiving materials such as concrete, rock, metal and the like by explosive powder charge operated setting tools. To achieve the high mechanical strength required for such nails, the nails are formed of two parts, one a shank and the other a head fitted onto the shank. While the head is formed of a deformable corrosion resistant steel, the shank is formed of an austenitic steel alloyed with nitrogen having a very high mechanical strength. The steel forming the shank can only be shaped to a very limited extent, whereby a narrow flange is provided on the rear end of the shank. A disk fitted on the shank serves as a guide for the nails during the driving operation.

Inventor: SELIG MANFRED DIPL CHEM DR
IPC: G05B19/042
Filed: 1992-02-27
Abstract: Disclosed is a process for the monitoring and control of charging processes involving a number of process steps which take place in a sequence at method-specific intervals and whose initial states are characterized by a specific parameter set. The said charging process is controlled by means of an automatic process control system incorporating a phase program (time program element) specifying a) the process-specific events in the form of their parameter-constellation, b) the chronological sequence of those process-specific events and c) the precise process-specific intervals between the events. The program element 1) initiates a new, relative time axis, when the specified program starts running or a process-specific event is recognized, 2) initiates the process steps to each time bring about the next appropriate process-specific event in the sequence, by integrating the phases of the specific program into the parameter-set, 3) compares, after expiration of the process-specific interval to the next event, the specific parameter-constellation for the start of the sequential event with the actual parameter-constellation in the process, and 4) if those parameter-constellations match, initiates the process steps needed each time to reach the next event in the sequence.
