Title: Guide bar segments for knitting machines - have plastic moulded guide formations on each segments
Inventor: GUTWALD VOLKER
IPC: D04B15/64
Filed: 1993-05-05
Abstract: The product is a yarn guide for knitting machinery which is in the form of segments to place together as a guide bar. Each guide of the segment is set apart to match the distance between the needles with which they function. At each end of the segment as half a guide distance. Pref. the segment has a base with fixing hole. The protrusions are shaped to form the yarn guides. Another protrusion keeps the yarn in the guide slot. The shaped part has a pin form leaving the place for the yarn. The yarn is brought from a beam in direction to each guide. The segments are arranged to fit together on a bar, and the end of one segment fits against the adjacent segment. Where needle spacing is close, the guide at segment ends will have to be formed in two halves. This is achieved with a plastic injection moulding technique, which can be formed as mouldings as an open channel, or projections as studs or pins, tubular passages, holes and slots, or combination of these. The segments may also have end formation to clip together. The segments may have a double formation to enclose the yarns when two parts are closed together, giving a quick release for threading purposes. The double sections are also arranged to have a snap action to clip together. Other separate elements may also be employed to secure the yarns into the guides. ADVANTAGE - The segments are easily handled, they quickly form into a bar, with reliable performance. The product is precise, efficient and long lasting. Setting up time is reduced.

Title: Process-control method for the surface machining of workpieces with pulsed laser radiation
Inventor: BARKHAUSEN WINFRIED DIPL PHYS
IPC: B23K26/12
Filed: 1993-06-21
Abstract: A process-control method is described for the surface machining of workpieces with pulsed laser radiation and, if need be, process gas. The invention is distinguished by the fact that the laser-beam parameters relevant to the respective machining, the radiation, reflected from the machining point, of the machining laser and/or a probe laser, and/or the radiation emitted by the machining plasma are measured on-line, and that the measured values are analysed by actual-value/desired-value comparison in an EDP-assisted control unit. With the aid of this analysis, control of the laser-beam parameters required for adapting the actual values to the desired values and/or of the position of the workpiece by means of a suitable handling system and/or of the feed of the process gas is effected with the use of the control unit.
Patent DE-4323465-A1 (DE)
Title: Temperature-control device for wax spraying machines
Inventor: JUNG HANS F DIPL ING
IPC: B29C45/78
Filed: 1993-07-14
Abstract: The temperature control of liquid wax to the optimum process injection temperature takes place conventionally by constant temperature regulation of the heat transfer medium. This regulation does not take account of the changeable mass throughput and therefore leads to great deviations from the set value in the wax. The proposed solution avoids these deviations and allows injection of structurally viscous wax. The temperature control process is completed during a sequence of control and regulation steps on a wax mass enclosed in the heat exchanger. For the subsequent wax change in a tube-bank heat exchanger, two solutions are indicated: A cooler with reversible flow is flowed through alternately in both directions, the separation of temperature-controlled and hot wax being maintained by floating pistons. A cooler with single-tube flow is flowed through in a timed manner in one direction, a mechanism in each case opening only one tube for flowing through. The device makes possible optimum adaptation of the temperature of wax on injection into the tool and thus guarantees a uniform accuracy of dimension and shape of wax models for example for precision cast parts using the lost-wax casting method. <IMAGE>

Title: Machine tool spindle unit compensating for thermal expansion - supplies oil under pressure to chamber between paired spindle bearings in response to displacement and angular velocity measurements
Inventor: HIBI KENJI
IPC: F16C27/04
Filed: 1993-09-29
Abstract: The spindle (4) is rotatable in pairs of slanted ball-bearings (6,7;8,9) with distance pieces (5). An annular spring (15) of U-shaped cross-section and an oil-pressure chamber (16) are arranged between the outer casing (1) and the spindle. The pressure control valve (18) responds to a controller (22) processing the signals from a displacement sensor (20) on the spindle end and a tachometer (21). When the rotational speed increases, pressure in the chamber is increased to reduce the tension so that the spindle moves axially and its displacement by thermal expansion is compensated. ADVANTAGE - Tension of bearings can be adjusted stably and reliably, and axial displacement of spindle minimised over wide range of speeds for more accurate machining.

Title: Security device for motor vehicles
IPC: B60R25/20
Filed: 1993-11-08
Abstract: Security device for motor vehicles which makes their putting into operation more difficult or impossible for an unauthorised third party. A control device is provided which controls at least one relevant function of the vehicle and interrupts this if an incorrect key device is used to put the vehicle into operation. The sensors with which the operating variables necessary for control are acquired are preferably individualised, so that an exchange of the control devices from vehicle to vehicle is possible only with a high expenditure. Furthermore, a second key device is preferably used which is not carried during operation of the vehicle and which serves for the purpose of predetermining a specific, variable time duration and/or distance, for example 14 days and 1000 kilometres, for the operation. If these values are exceeded without the second key device having been used once more, the control of the relevant vehicle function(s) is blocked. Hence, stealing a vehicle or purloining a rented car also becomes pointless.

IPC: B23K20/00
Filed: 1994-06-22
Abstract: A ball-production device which exhibits no parameter variations originating during setting of the spark-discharge control parameters, the variations depending to a great measure on the operator or the device. In order to set the spark-discharge parameters, digital data for controlling the spark discharge are transmitted serially from a wire-bonding control device to the ball-production device and the digital data being used for setting parameters such as discharge current, discharge time, heat production and the like. The discharge-state data acquired during the spark discharge are transferred serially from the ball-production device to the wire-bonding control device such that the above desired parameters are used for regulation. Non-uniformities or differences in ball size, which can vary from device to device, are eliminated, and an improved bonding capacity results. Unnecessary bonding processes are reduced and improved productivity with semiconductors is achieved.
