Title: Synchronising arrangement for thyristor frequency changers
IPC: H02J3/42
Filed: 1974-01-29
Abstract: 1465151 Automatic phase control systems SIEMENS AG 29 Jan 1974 [29 Jan 1973] 4187/74 Heading H3A [Also in Division H2] A frequency changer arrangement comprises a pair of frequency changers I, II, each having a thyristor inverter 3, 12 and means for synchronizing the frequency changers including control means 20 having a first input responsive to signals indicating the time of firing pulses for a thyristor of one of the inverters and a second input responsive to signals indicating the time of firing pulses for the corresponding thyristor of the other inverter, the control means 20 being arranged to vary the frequency and phase of one of the inverters so that the two inverters are synchronized. When the phase of triggering pulses from source 18 agrees with that of source 51 the AND gate 21 detects a coincidence and feeds a signal to a further AND gate 25 and initiates a counter 24 which enables AND gate 25 after a predetermined number of such coincidences. AND gate 25 then provides a signal for changing over the output of the two inverters 3, 12 to the common load. The invention is applicable to the supply of adjustable frequency power to synchronous motors 10 in man-made fibre apparatus. Motors 10 are initially supplied by frequency changer I which comprises a phase-controlled rectifier 1 feeding an intermediate D.C. circuit 2 which in turn feeds a thyristor inverter 3. The output frequency is manually adjustable by changing the frequency of the source 51 of triggering pulses, e.g. from a quartz oscillator feeding a digital circuit via manually adjustable decade switches. Alternatively, an analogue frequency source may be used. If it is desired to replace frequency changer I by II, sources 18 and 51 are set to the same frequency and the intermediate D.C. voltages are compared by means of a differential amplifier 28, the error being fed to a voltage-setting means 13 which brings the output of rectifier 11 into correspondence with that of rectifier 1. A limit value device 27 then feeds a first signal into AND gate 25. The trigger pulse for thyristor 31 of converter I and that for the corresponding thyristor in converter II are shaped by 22 and fed to AND gate 21 which sets a trigger circuit 23 in the event of non-coincidence. Circuit 23 then changes the frequency of source 18 by an integer #F2. When phase coincidence is reached, AND gate 21 produces a signal for counter 24 and AND gate 25 so that after a predetermined number of such phase coincidences (as determined by counter 24) counter 25 sets a trigger 26 which energizes contactor 15 so as to connect converter II to the bus-bar 9 and, after a delay, opens contactor 8 to disconnect converter I.

Title: The production of positive photographic images by heat development
IPC: G03C5/315
Filed: 1957-02-07
Abstract: 821,506. Photographic processes. AGFA A. G. Feb. 7, 1957 [Feb. 18, 1956], No. 4246/57. Class 98(2) Positive images are made by exposing a silver halide emulsion layer containing a tanning developing agent, heating the layer to a temperature of 80-150C. to reduce and harden the emulsion at the exposed areas, keeping the layer in contact with a transfer layer at 80-150C. to transfer unexposed emulsion thereto, separating the two layers, and subjecting the transfer layer to reducing conditions to form a silver image therein. The reducing conditions may be provided by exposing the transfer layer and heating it to 80- 150C. The separate heating of the emulsion layer may be omitted and in this case the reducing conditions may be attained by providing reducing substances in the transfer layer. Several copies may be taken from one emulsion layer but the latter should not be exposed to light during this procedure. In ten examples the separate heating of the emulsion layer is always omitted, thus in Example 1 a gelatine-silver halide emulsion containing pyrocatechol, terephthalaldehyde bisulphite, sodium acetate and benztriazole as on a paper support is exposed, heated as at 110-120C. for 5 to 30 seconds whilst in contact with an acetyl cellulose acetobutyrate coated paper constituting the transfer layer and the latter is separated, exposed to dull light and reheated to show a deep black positive image of the original. In Example 2 a somewhat similar emulsion but containing also a proportion of metol is exposed and processed as in Example 1 using piperazine in the transfer layer but with omission of the after-treatment of the latter since blackening is effected by the piperazine. The remaining examples mostly follow the procedure of Example 1 and numerous further substances and supports for use in the process are referred to in these examples and in the body of the description. Specifications 655,273 [Group XXX], 790,811 and 801,053 are referred to.

Title: An improved method of and apparatus for joining together strips of flexible or semi-flexible material
IPC: B27D1/10
Filed: 1928-02-14
Abstract: 311,683. Williams, W. N. Feb. 14, 1928. Feeding sheets; sheet-separators. - In an apparatus for joining together strips of material edge to edge, particularly strips of veneer, two strips are placed so that their edges overlap, the overlapping edges are cut simultaneously, and the cut edges are coated with glue and pressed. As shown in Figs. 1 and 2, two piles a<1>, a of strips are positioned by guides b<2>, b<3> on tables b, b<1> adapted to be raised as the piles diminish. The piles are separated by a wall c<1> having an inclined top c<2> and are held under compression by spring stops c<4>, c<5> and a guide member c<3>, of the shape shown, having a part extending above the pile a<1>. The uppermost strip of the pile a<1> is fed laterally into the guide c<3>, to overlap the pile a, by rotatable rollers d normally held clear of the pile by springs but lowered for the feeding stroke by cams d<3> and bell-crank levers d<2>. Alternatively, or in addition, pneumatic pickers may be used for the lateral feed. The two uppermost strips, with their edges now overlapping, are fed forward by rolls g normally raised by springs but lowered for the feeding stroke by cams g<4>. They pass by a pressure roller i to a disc-knife k operating through a slot in a table h, and thence to a glueing-wheel mm. Means may be provided for dealing with more than two strips at a time. Alternatively, the stripfeeding means may feed the two strips obliquely towards each other until their margins overlap. In another modified arrangement, Fig. 5, single strips are fed successively through the machine, with the edges to be cut and glued lying transversely of the machine. The strips a are held on the moving table b by stops c<8>. The uppermost strip is lifted and carried forward to fixed stops r<1> by a pneumatic picker r. The latter is reciprocated by a rod r<8> and crank disc r<10> along guides r<5> which are shaped to raise the picker slightly at the commencement of its forward stroke, to lift the top strip A initially, at which point also the suction is applied. At the stops r' the sheet A is released with its forward edge overlapping the rear edge of the preceding sheet A<1>. The overlapping edges are pressed by a bar s while they are cut by an inclined disc cutter k. After cutting, the strips A, A<1> and also the preceding strip A<2> are moved forward by feed members t operated by a crank disc t<8>, t<6>, rods t<5> and levers t<4>. Specification 269,336, [Class 145 (i), Wood cutting], is referred to.
