Title: Apparatus for automatically charging a laminating station
IPC: H05K13/00
Filed: 1985-05-23
Abstract: An apparatus for the automatic feeding of a carrier to a laminating station. The apparatus has a gripper device which is fastened to two guide rods and which is movable t o anf fro horizontally. Each of the guide rods is guided in a linear guide and is mounted in supports which are connected to one another by means of an angular cross-strut. A pneumatic cylinder is articulated centrally to the angular cross-strut by a lengthened piston rod. The gripper device grips the carrier at a predetermined distance (Xmin) from the front edge, to transport it in the direction of a laminating station. A sensor for detecting the front edge of the carrier which is transported into the gripper device is located on a holding bracket fastened to a displaceable holding block. The upper and lower gripper strips each have a perforation in the center of their bevelled strip part. As soon as the front edge of the carrier interrupts the vertical beam path, the sensor generates a control pulse which closes the gripper device and which retains the carrier for the transport to the laminating station.

Patent EP-0182300-A3 (EP)
IPC: G01V1/02
Filed: 1985-11-14
Abstract: An airgun impulsive energy source has an elongated shaft 
bearing surrounding the shaft of the reciprocatable shuttle for 
guiding the shuttle and preventing its operating or firing pis­
tons from contacting their respective cylinder walls. The illus­
trative embodiment of this airgun is proportioned to be self-fir­
ing with a fast repetition rate. This airgun has an elongated cy­
lindrical housing with discharge ports in a cylindrical wall posi­
tioned between the operating and firing chambers. The shut­
tle-guiding shaft bearing is positioned in the cylindrical hous­
ing between the ports and an operating chamber. This shaft-­
guiding bearing has a length which is more than 1.7 times the 
diameter of the shuttle shaft, while the operating and firing pis­
tons have diameters which are slightly less than the diameter 
of their respective cylinder walls for eliminating contact of 
these pistons with their cylinder walls, thereby advantageously 
dramatically increasing the firing cycles which can occur be­
fore the need for replacing any worn parts. Moreover, only the 
shuttle shaft guiding bearing is replaced, instead of the cylin­
der walls. The housing includes internal through passages 
which convey high pressure gas longitudinally through the air­
gun so that it can be coupled to subsequent airguns con­
nected in series with the first one. Thus, a single source of high 
pressure gas may be utilized and fed in series through a se­
quence of airguns forming a flexible 'string' of airguns capable 
of being inserted into and used for cleaning pipes of heat ex­
changers, boilers, water heaters and other internal regions of 
closed vessels, which are normally very difficult or impossible 
to reach into for cleaning. The discharges of pressurized gas 
by the string of airguns in liquid, usually water, in such equip­
ment is used to dislodged sediment and deposits from the inter­
nal surfaces of such confined regions so that the loosened for­
eign material can then be flushed out by the flowing liquid.

Title: Opto-electronic position determination device
IPC: G01D5/38
Filed: 1986-09-17
Abstract: A position measuring instrument, comprising a scanning grid, a scale grid and an illumination unit, is used to produce two sets of diffracted partial light rays. The scanning grid defines a grid constant and is formed by two scanning fields, constructed as phase grids, offset to one another in the measuring direction by 1/4 of the grid constant. The phase grids have a slat-to-furrow width ratio that deviates from a 1:1 ratio. The scale grid has the same grid constant as the scanning grid but has a slat-to-furrow ratio of 1:1. The grids cooperate with the illumination unit to produce diffracted partial light rays of several orders. An oppositely deflecting prism is allocated to each scanning field. A first and second set of diffracted partial light rays are generated, wherein the second set is opposite in phase to the first set. A photodetector is allocated to each respective selected order of the two sets of light rays to produce corresponding electrical signals.

Abstract: A bus interface for interfacing between a processor and 
a shared bus is disclosed. The bus interface allows the exchange of 
data in the form of packets between the bus and the processor. An 
interface control device exchanges control data with the shared bus 
(e.g. identification signals, polling signals, control signals) in 
order to regulate accesses of the interface circuit to the shared bus. 
State machines (e.g. a transmitter and a receiver) including data 
pipelines, are responsive to control signals from the interface 
control device for exchanging data between the shared bus and a data 
storage device. An access control device both controls the flow of 
data between the processor and the data storage device and regulates 
access to the data storage device between the processor and the state 
machines.

Patent EP-0258621-A3 (EP)
IPC: H04J3/06
Filed: 1987-07-27
Abstract: The transmitter in a digital communication system 
sends a synchronization sequence that uniquely identifies 
the polarity of the received data. From the received 
data (418), the receiver produces non-inverted and 
inverted polarity data streams (358, 358′) that couple to 
like synchronization detectors (200, 200′). Only the 
detector to which the correct polarity data stream is 
coupled responds. Logic circuitry determines which 
detector responds and, accordingly, selects the polarity 
of received data to be further processed by the receiver 
(422).  
     After polarity is established (60), both detectors 
monitor the received data stream of the selected polarity 
to determine whether synchronization shifts after having 
been initially established. Monitoring continues until 
terminated by other receiver circuits.

Title: Optical fiber dispersion transformer
IPC: H04B10/18
Filed: 1987-08-07
Abstract: An optical transmission system is described wherein light is transmitted from a transmitter (Tx) to a receiver (Rx) by at least one transmission optical fiber (11). The system includes a dispersion transformer (13) which receives light from one of the components, compensates for or transforms the delay distortion of the various wavelengths transmitted through the system, and provides the next component in the system with a compensated or transformed light beam. The dispersion transformer (13) comprises means for receiving light from one of the components and dispersing/separating the light into a plurality of spatially separated beams which are directed onto the endface of a multimode optical fiber (16). The position of each beam on the endface of the multimode fiber (16) is a function of the velocity with which the light that forms the beam propagates through the transmission optical fiber (11). The multimode fiber (16) is characterized by a refractive index profile and a shape which are such that the modes excited therein are propagated therethrough with appropriate delays to generate an output pulse of desired width. Dispersion can be reduced or increased. Light emanating from the multimode fiber (16) is coupled to the next adjacent component of the system.

IPC: G01R33/26
Filed: 1988-04-22
Abstract: A helium magnetometer includes a helium cell (1) containing helium, preferable 
⁴ He . A solid state laser (4) strikes the helium cell at one end with a laser having 
a wave length of 1082.91 nm in the embodiment of a ⁴ He  cell. The helium atoms 
precess at known frequencies for different magnetic fields. The transparency of the 
helium cell at 1082.91 nm with ⁴ He  is a function of the resonance of the atoms within 
the helium cell. A radiation detector (9) positioned on a second end of the helium cell 
opposite the end where the laser strikes detects the laser when transmitted through 
the helium cell and produces an electrical signal in response to the transmitted laser. 
The resonance of the helium cell is enhanced by a Voltage Controlled Oscillator, VCO 
(19), which provides a variable output frequency to a pair of coils (8, 12) positioned 
on the sides of the helium cell and electrically connected to the VCO to receive the 
variable output frequency. The pair of coils produces a variable magnetic field at 
the precession frequency that is mathematically related to the magnetic field that 
is being measured and thus enhances the precession of th atoms within the helium 
cell. A feedback loop (9, 11, 13, 15) includes a demodulation circuit (13, 15) that is 
electrically connected between the radiation detector and the VCO and demodulates 
the electrical signal from the radiation detector to produce a drive voltage for driving 
the VCO.
