Title: Electronic digital clocks
IPC: G04G15/00
Filed: 1975-11-27
Abstract: 1523128 Electronic timepieces; automatic control KIENZLE UHRENFABRIKEN GmbH 27 Nov 1975 [27 Dec 1974 25 Feb 1975] 48720/75 Headings G3N and G3T A digital electronic clock is programmable to produce an electrical output at a predetermined time(s) e.g. for triggering a switching function in an external apparatus. In Figs. 1, 4 embodiment, the clock comprises a digital electrical display 12 (e.g. LEDs) driven by a logic circuit 11 in response to BCD signals from an output 4 of a timekeeping circuit 2 controlled by a crystal oscillator 1. A multi-plexer 3 controls a sampling circuit 8 including gates G 15  to G 19  for each memory store to sample successively the individual decades of BCD values pre-set into a programmable memory 9' or 9" (i.e. values representing tens and units of hours, tens and units of minutes and date). A comparator circuit 6 compares the sampled values with BCD signals from an output 5 of the timekeeping circuit 2. If the stored values coincide with the clock output 5 the comparator produces an output at a terminal 13 which is selectively applied by an address gate circuit to produce an output at 22' or 22" in accordance with stored value in stores 9' or 9" respectively for triggering a respective switching function. The timekeeping circuit 2 also supplies pulses to the multi-plexer 3 which in turn determines the switching sequence of coded signals from output 4 of circuit 2 and through the display logic circuit 11. Control of the sampling of the stores by the multi-plexer 3 is effected through a digit driver circuit having outputs D 1  to D 6  at f 1 . The output D 1  for example controls all of the gates G 15  which are associated with the decades 15 (tens of hours) of all the stores 9. Output D 2  controls gates G 16  and so on. At the occurrence of the first sampling pulse from multi-plexer 3 all the gates G 15  receive a pulse from D 1 . At the second pulse D 2  sends a pulse to G 16  gates and so on. Another input to the gates G 15-19  is from a bi-stable trigger stage 20 (or alternatively from a shift register where more than two stores are used). The trigger 20 is controlled by pulses at f 1 /6 from the multi-plexer so that with five successive pulses at f 1  the decades of one store are successively sampled and after a sixth pulse the next five pulses sample the second store, the trigger output high level switching from Q to #. As shown in Fig. 1 the comparator compares the sampled values on lines (1) and (8) with the BCD clock signal from output 5 of the timekeeping circuit. Upon coincidence an AND gate G 20  out-  put advances a counter 21 one step. When five such coincidences occur for a store 9, the counter 21 applies a signal to an output unit 13. The stores illustrated may be programmed by interrupting selected printed circuit conductors to constitute an open switch. Alternatively the coded input to the stores may be effected by punched cards, tapes or digital reels. Each fixed value store may consist of a plug-in printed circuit board.

Patent GB-1024546-A (GB)
Title: Improvements in and relating to an apparatus for monitoring the thread in a textile bobbin-frame
IPC: B65H63/06
Filed: 1963-12-19
Abstract: A method for controlling the thread in a textile bobbin frame by means of monitoring the thickness of the thread is characterised that when the thread thickness deviates from a predetermined range the length of the faulty thread section having the deviation is ascertained and used to initiate a control process-for example to cut or clean the thread, or to stop the machine or a counting mechanism, or to photograph the thread.  The thickness modulating device may comprise capacitor plates, or a photocell which may be modified to measure the average thickness of the thread in a plane normal to the length of the thread.  The electrical output from either device is used to modulate a signal voltage.  The resulting wave form 31, Fig. 4 (not shown) is passed through a discriminator to produce a series of pulses 32 corresponding in number and length to the faulty thread sections. The subsequent processing step may be initiated when the length of a pulse is greater than a threshold value, or the lengths may be integrated so that the "resulting length" if greater than a certain value, is used to initiate the processing step.  In Fig. 4 wave 32 is integrated to form a zig-zag wave which is increased in height during a pulse, and decreased in height during the absence of a pulse, with the height of the wave being the "resulting length". In Fig. 7 (not shown) the wave is integrated to form a stepped wave 38 which is periodically interrogated to obtain the resulting length, and at the same time is reduced to zero.  Alternatively a function of the length L of the faulty thread section and of the maximum amplitude a of the thickness of the thread may be used to initiate the processing step if the function exceeds a threshold value.  In Fig. 6 (not shown), the signal is passed through an amplifier 5, a length channel comprising a Schmitt trigger 119 and a Miller integrator 120, a linearly operating amplifier 118, a combining circuit 127 which adds the resulting length wave form and the amplitude, and a discriminator 7 whose threshold is regulated by rectified and smoothed the signal wave from amplifier 5.  In Fig. 11 (not shown) the signal voltage is fed to trigger and modulator which produces a pulse of length L and height proportional to a, which pulse is fed to an amplitude discriminator, an integrator, and a length discriminator.  In Fig. 12 (not shown) the outputs from an amplitude discriminator and a length discriminator are fed into a coincidence circuit.  In Fig. 14 (not shown) a pulse of length L and height a is fed to a combining circuit which produces a pulse of amplitude proportional to aL2.  The stepped wave form 38 of Fig. 7 may be obtained optionally by using light source, lens, slot and photo-element-Fig. 9 (not shown).  The position of the thread is adjusted so that only the image of the faulty thread section fall across the slot and thus causes a signal in the photo-element.

Filed: 1963-12-23
Abstract: 1,069,498. Spinning viscose. BEAUNIT CORPORATION. Dec. 23, 1963, No. 50726/63. Heading B5B. Regenerated cellulose filaments, films &c. are produced by extruding a viscose containing a soluble viscose-coagulating salt of a strong base and a weak acid in a proportion insufficient to cause coagulation of the viscose prior to its extrusion into an acid-salt spin bath in the presence of a polyalkylene glycol of average molecular weight at least 400, or a derivative thereof, and a water-soluble hydroxy fatty acid. The viscose coagulating salt may in particular be a soluble sulphide, but may alternatively be, for example, sodium acetate or sodium phosphate. The hydroxy fatty acid preferably contains 2 to 6 carbon atoms in the molecule and the hydroxy group is preferably in the alpha position. The viscose coagulating salt is preferably a salt of a metal, particularly sodium. The term "soluble" as applied to these salts refers to their being soluble in viscose, irrespective of their solubility in water. The viscose coagulating salt is added only to the viscose. The glycol (or a derivative thereof) and the hydroxy fatty acid may be added to the viscose or to the spin bath or both. The viscose preferably has a salt point of about 7À5 to about 9À0. The spin bath may contain a zinc salt in a concentration of preferably about 4 to 8% or more. If a derivative of a polyalkylene glycol is used it may be an ether or ester derivative of a fatty acid, the derivative having a polyoxyethylene chain containing at least 25 ethylene oxide and/or propylene oxide groups.
