Title: Protective device for weld platens - prevents closure if the intervening space is not covered
Inventor: BOLTER GERMAN
IPC: B29C65/00
Filed: 1975-05-07
Abstract: In a protective device for a weld platen which carries out a closure movement for the prodn. of a weld seam bonding a film type material and is then pressed against a second weld platen in the zone of a squeeze position (a) a cover is supported on the weld platen and projects over the weld tool in its rest position in such a way that it can be displaced elastically from its rest position oppositedy to the direction of the closure motion (b) as a result of this displacement from the rest position with respect to the weld platen, a protective switch fixed either on the weld platen or on the cover itself, can be operated prematurely interrupting the closure motion (c) a bridging switch mounted on the frame carrying the weld platen by-passes the protective switch and prevents the premature interruption of the closure motion and operates the closing weld platen as soon as the lower edge of the cover in its rest position lies directly over the film-type material to be welded together. Prevents closure of the weld platen if the packaged article or the operator's hand is present in the path of the closing weld platens.

Title: TV receiver automatic and visual monitoring - SES TEST VOLTAGE COMPARISON CIRCUITS, LEDs and power switch
Inventor: ROHRBACHER JOSEF
IPC: G01R31/28
Filed: 1975-05-17
Abstract: The circuit for rapid diagnosis and continuous monitoring of functionally separate elements of modular television receivers, measures voltages at test points of the functional elements and displays the results on LEDs. The monitoring signals fed to the LEDs are also connected to an AND-gate whose output controls a thyristor switch for the receiver power. Time constant elements may be provided on the AND-gate inputs to ensure continued operation in the event of short-duration errors. Voltages with small loads are monitored by FETs with current amplification stages, and pulsed voltages with short duty cycles are rectified to drive suitable small signal transistors.

Title: Transmission error detector for biphase coded data signals - compares first bit half with second bit half and indicates error if same two quantites coincide
Inventor: POELLATH KLAUS
IPC: H04L25/49
Filed: 1975-05-23
Abstract: the transmission error detector, for biphase coded data signals, stores the binary quantity representing the first half of each bit of the biphase data signal and compares it with the binary quantity representing the second half of that bit.

Title: Approximating circuit for clock units in telephone exchange - compares contents of counters associated with each clock
Inventor: DIETL RUDOLF
IPC: G04G9/00
Filed: 1975-07-21
Abstract: The automatic approximating circuit is used for a clock unit, which is in error in comparison to a control clock unit, with the latter used for tariff switching in a telephone exchange. The circuit compares the contents of counters associated with each clock unit, the contents of each counter representing the time displayed by the clock unit. The comparator supplies a signal in response to disagreement between the contents of the two counters, which together with setting criteria for the unit in error, are used to supply pulses with a higher frequency, until comparison between the clock units is obtained. The next forwarding pulse for the control clock is also supplied to the counter associated with the corrected clock unit, the correction pulses being released at the same time, so that synchronism between the clock units is obtained.

Abstract: (Dis)continuous one- or multi-stage polymerisation of ethylene (I), opt. mixed with max. 10 mole% 3-6C alpha-olefins (II) in hydrocarbon dispersant (III) at 2-40 bar and 60-100 degrees C, opt. using H as mol. wt. regulator, is carried out with a solid catalyst (IV) activated with gp. (I), (II) and (III) metal organyl, (IV) being the reaction prod. of cpds. (V) of the formula Ti(1-a)Ala(OR)n(1-a)(OR')maX4-a-n+an - am (in which a=0-0.9, pref. 0-0.3, n=0-4, m=0-3, m+n=0-6, prf. 0.5-4, R and R' are linear or branched 1-20, pref. 2-4C alkyl or aryl gps. X is halogen, pref. Cl) with Mg in ether (VI). Redn. can be carried out in the heterogeneous phase, allowing the use of Mg instead of costly Mg organyls. With this catalyst, there is less tendency to form ethane when H is used as regulator. The catalyst has high activity and the polymer contains only a trace of Ti cpds., so that purificn. is unnecessary. The polymers have high stiffness and impact strength, very good thermal stability and good processability. In an example, (IV) was produced by treating activated Mg powder and Ti trichloroisopropylate with diethyl ether and activated with Al triethyl. When used in the polymerisation of (I) at 6 bar, using H at 4 bar, the polyethylene yield was 70 g/mg Ti in 1.5 h.

Title: Carbonation column for sodium hydrogen carbonate prodn. - has perforated trays with drains adjacent vertical pipes
Inventor: PANOV VADIM IVANOVITSCH
IPC: C01D7/07
Filed: 1976-03-19
Abstract: A carbonisation column for producing a suspension of sodium hydrogen carbonate contg. a solid crystalline phase comprises a series of perforated trays with vertical over-flow pipes passing through them, also a cooler in the lower part of the column. In each reaction chamber, the top of the vertical over-flow pipe is surrounded by a coaxial annular protector plate with an annular gap between them. The region of the tray immediately surrounding the pipe is unperforated and there is a discharge device, esp. an aperture in the pipe wall, at an appreciably lower level than the rim of the pipe, to permit discharge of the suspension together with the solid crystalline phase contained in it. As an alternative to the aperture, there is a separate small vertical drain pipe close to the vertical pipe. Uneven distribution of the solid phase across the tray, and accumulation of crystals, are reduced. Thus maintenance is reduced and a more uniform crystal size is obtd.

Title: AC=DC voltage conversion appts. - uses semiconductor switch between rectifier and load and storage element in parallel with load
Inventor: SIEGEL EMIL
IPC: H02M7/217
Filed: 1976-08-02
Abstract: The switching voltage is generated by comparing a delta voltage of double the mains frequency and a control voltage dependent on a comparison of rated and actual values. The delta voltage can be derived from the ac mains voltage by full-wave rectification, conversion into a sinewave voltage and limitation into a square-wave voltage. The ac mains voltage is applied to a full-wave rectifier whose output is connected to an active filter generating the sine-wave voltage of double the mains frequency. Its output is connected to a limited stage which converts the sine-wave voltage to a square-wave voltage. The limiter stage is connected to an integration stage which converts the square-wave voltage into a delta voltage.
