Title: Sample analyser using time-of-flight mass spectrometer - using pulsed laser beam to ionise sample adjacent to ion optics system
Inventor: ABERLE LOTHAR
IPC: G01N21/00
Filed: 1977-08-03
Abstract: The sample analysing appts. includes a microscope (5) for collimating a laser beam onto the sample (6) and for observing the sample, and an ion optics system (8-10) for guiding ions emitted by the irradiated sample to a time-of-flight mass spectrometer (11). The sample is illuminated by a lens and mirror system (18-24) to permit its observation by transmitted light. An electro-pneumatic drive (16) moves the ion optics system and the lens and mirror system (18-24) perpendicular to the axis of the ion optics system to align one of them with the optical axis (17) of the microscope. The mass spectrometer is enclosed in a housing (1) whose end well is closed by a cover glass (4). The ion optics system and the lens and mirror system may be mounted on a movable rod (14) which projects laterally from the housing.

Title: Pump head for rope operated deep well pump - has swivel bolt attachment on either side of beam for easy maintenance
Inventor: GAUS HEINRICH
IPC: F04B47/02
Filed: 1977-08-06
Abstract: A pivoting beam carries a pump head at one end from which a rope drops to the pump rod guide. The pump head is attached to the beam by two rods, one on each side of the beam. The head has flanges on each side which match flanges on each side of the end of the beam. Swivel screws with wind nuts hold each pair of flanges together. When the screws on the top and bottom flanges on one side are slackened the head is free to pivot about the rod on the ohter side. Thus a simple mechanism enables the head to be swivelled to either side as required for greater ease of maintenance.

Patent DE-2744116-A1 (DE)
Inventor: WINTER RUDOLF
IPC: H04Q3/00
Filed: 1977-09-30
Abstract: In a circuit arrangement for identifying subscriber lines (Tln) involved in a switching process on the basis of corresponding identification request signals, an identification signal is transmitted for a cycle test via the initiating switching element and the connection path (AS-GW) already set up to the relevant subscriber line circuit (TS). From there, it passes via an identification network (CE) supplying its address to a device (IDC) which sends out the identification signal, evaluates the identification result and forwards it. To handle one and the same identification request, coded identification signals in each case effecting an identification process are periodically successively sent out. At least the duration of the pulse time and the interpulse time of an identification pulse are taken as identification signal. The periodic occurrence in the receiving circuit (SE) is detected and the result obtained from the identification process is only released for further processing by a subsequent device with a repeated correspondence in the evaluation of successive identification signals. A static comparison of potentials between the drive pulse for the transmitter (S) and the received signal is carried out. <IMAGE>

Title: PAL clock generator preventing phase jitter of pulse flanks - uses oscillators, mixer and comparator to produce precision offset frequency
Inventor: OBREMSKI MICHAEL
IPC: H04N9/45
Filed: 1978-03-14
Abstract: The PAL clock generator mixes the outputs of two oscillators oscillating at frequencies spaced by the offset. The mix is compared with the offset frequency obtained by division from one of the two oscillators. The control voltage resulting from this comparison is used to change the second oscillator's frequency. The first oscillator or both oscillators may be quartz crystal types. A phase locked loop is used to produce the precision offset frequency and receives the frequency divided output of one oscillator.

Title: Keeping pressure of moulding cpd. inside tool constant - using control that detects and signals difference between charging force and mould-locking force
Inventor: ETTLINGER RODERICH
IPC: B29C45/80
Filed: 1978-03-16
Abstract: Control arrangement at a mould e.g. an injection-mould that has been charged under pressure and is kept locked by an exterior locking force, serves to maintain the vol. of injected moulding cpd. constant. There is a measuring installation mounted at a machine part connected with the mould, that responds to the movement of the mould under the action of the charging pressure. A regulator is connected to the exit of the measuring installation, acting upon an element that affects supply of moulding cpd. The regulator measures only that difference between the charging force acting against the locking force by virtue of the pressure of the moulding cpd. and the locking force, insofar as that difference exceeds the locking force. When this difference reaches a positive threshold value than a signal is released. Real maintaining of charge vol. is obtd. by indirect measurement of mould-breathing or removal of stress from both half-moulds at the parting plane.

Patent DE-2843699-A1 (DE)
Inventor: FROIDEVAUX JACQUES
IPC: G04D7/12
Filed: 1978-10-05
Abstract: A method and apparatus for measuring the frequency error of a timebase frequency of a quartz timepiece, relative to a reference frequency. An input signal having a frequency equal to the timepiece timebase frequency is produced from the timepiece. The input signal is applied to a passive quartz crystal filter having a resonant frequency equal to the reference frequency, and which filter produces an output signal in response to the input signal. The phase of the input signal and the output of the passive quartz crystal filter is compared and at least one phase comparison signal related to the phase difference of the two signals is produced. The phase comparison signal drives a meter having a dial graduated in frequency error units to display the frequency error.
