Title: Controlling a stepping motor by a variable frequency oscillator
IPC: G05B19/40
Filed: 1972-09-14
Abstract: 1404774 Automatic control of movement ELEKTROMAT VEB 14 Sept 1972 42655/72 Heading G3N [Also in Division H2] A stepping motor 4 is controlled by a circuit comprising a variable frequency oscillator 1, a controller 3, a reversible counter 2 and a variable impedance network 5, the arrangement being such that the oscillator frequency is determined by the state of the counter 2 whose outputs 2‹ - - - 2n control respective switching transistors To - - - T n  of the network 5 to vary the conductance G of the latter and hence the time constant of the oscillator. The controller 3 includes a pulse-shaping unit, a reference counter, comparator and coincidence stages, a pulse distributor and a pulse amplifier feeding the windings of the motor 4. Members 2, 3 receive a squarewave pulse train from the oscillator 1 and the controller 3 sets a predetermined pulse value a corresponding to a desired number of motor steps, for example as obtained from a punched tape. In a typical operation involving acceleration, constant speed running and braking of the motor, pulses are fed to members 2, 3 and the oscillator frequency progressively increases until the reference counter reaches a value b, whereupon the controller 3 stops the counter 2. The motor then runs at a speed dependent on the value b (in counter 2) and fixed and variable oscillator time constants dependent on elements R', C', R"' and G, C". The reference counter counts up to a value a/2 and then counts down. When a count value (a-b) has been reached, the counter 2 is restarted I in the reverse direction and the oscillator frequency progressively decreases until both counters simultaneously reach zero and the motor stops. Thus the frequency/time characteristics for acceleration and braking are mirror symmetrical, Fig. 2 (not shown). If b is greater than a/2, there is no steady speed condition since the counter is not stopped but counts down with the reference counter when its value reaches a/2.

Title: Film transport systems
IPC: G03B23/12
Filed: 1973-09-19
Abstract: 1441111 Film transport systems SCRIPPSCLEMANS Inc and L W BUTLER 19 Sept 1973 [20 Sept 1972] 43937/73 Heading G2E Successive frames of film are moved through a gate by generating and applying a first position signal to a motor which moves the film frame into the gate, and then a second position signal which positions the frame precisely. The system may be applied to either a camera or a projector. The film is transported by a sprocket wheel 35 driven by a servo motor 41, the same shaft also carrying a positioning disc 42 and ending in a velocity tachometer 44. A constant speed motor drives a pair of sprockets which maintain a loop of film on either side of the gate, and also drives, via a shaft 59, a synchronizing disc 50. Disc 50 has, as seen in Fig. 9, six spaced holes 98, and the disc is mounted as seen in Fig. 8, between a light source 96 and photo-cell 97 which are carried by a bracket 70. Thus as disc 50 is driven by the constant speed motor, a series of pulses is produced as the light passes through the holes 98. Disc 42 is shaped as seen in Fig. 7, having a series of vanes 91 and holes 92, each hole being aligned with the leading edge of a corresponding vane. The disc is mounted on the shaft of the servo motor 41, as seen in Fig. 6, so that it is positioned between a pair of light sources 75, 77 and a pair of photo-cells 78, 79 which are carried by a bracket 74. In operation, disc 50 is rotated by the constant speed motor, thus producing a series of pulses from photo-cell 97 which are applied to the servo motor 41 which drives the film advancing sprocket 35, the film being advanced through the gate at the rate of one frame for each pulse. The control circuitry, Fig. 10 (not shown) is designed to produce a rapid acceleration and deceleration of the sprocket, without being so abrupt as to distort or damage the film sprocket holes. The rapid pull-down time allows a longer period for exposure or projection, so giving improved image brightness and quality. The output signals from photo-cell 78, which is controlled by the edge of vane 91 moving into the light path, and photo-cell 79, which is controlled by the holes 92 moving through the light path, are summated with the output signal from photo-cell 97, to position the film precisely in accurate registration with the gate.

Title: Improvements in or relating to document feeding apparatus
Inventor: DERC ROMAN
IPC: B62D3/02
Filed: 1969-09-05
Abstract: 1,274,766. Feeding sheets. INTERNATIONAL COMPUTERS Ltd. 8 Sept., 1970 [5 Sept., 1969], No. 44026/69. Heading B8R. Document feeding apparatus includes means for supporting a pile 1 of documents, e.g. a table 2, document feeding means, e.g. a suction drum 4, spaced from one end of the pile and separator means, e.g. a movable suction shoe 6, being operable to separate an edge portion of a document from the pile and to move it towards the feeding means, a knife 5 being movable into the space between the edge portion and the pile and sensing means sensing the thickness of said portion and withdrawing the knife and inserting it again when the sensed document thickness does not correspond with a single document thickness. The blade knife 5 and shoe 6 may be mounted on arms 13, 8 respectively, each pivotable about an axis 9 and urged anticlockwise by springs 14, 10 respectively. In operation, an electromagnet 15 is activated by a signal when a document is required to be separated and fed, to attract a metal block 16 on arm 13 thereby pivoting the arm clockwise retracting the knife 5 from its supporting position below the pile which thus allows the portion of the lowermost document not supported by table 2 to be attracted downwardly towards the suction shoe 6. This shoe may have a concave surface causing the sheet to buckle and facilitate prevention of double feed. The knife is then returned to its original position, the separated document being sandwiched between it and the shoe 6 which latter is then removed by pivoting the arm 8 via electromagnet 11. The document is thus attracted to the rotating suction drum 4 and, optionally, engaged by pinch rollers, not shown, and fed away past guide member 30 and pinch rollers 19 to a conveyer 18, e.g. rollers. The sensing means, e.g. a finger 22 connected to an inductor 24, senses the thickness of material separated and held between the knife 5 and shoe 6, and causes the knife to retract and return until a single document is separated. The suction drum may be rotated, through a clutch.

Abstract: 1311232 Heat exchange apparatus ENERGIAGAZDALKODASI INTEZET 21 Sept 1971 [21 Sept 1970] 44054/71 Headings F4S and F4U Heat exchange between a hot gas stream flowing through a plurality of lower passages 2 and a cold gas stream flowing through a plural: ty of upper passages 1 is effected by means of heat transfer devices each comprising a vertical enclosure 3 containing a vaporizable liquid 4 and extending perpendicularly to the passages 1 and 2. The passages, which are of flattened cross-section, very narrow (<0À7 mm.) and formed in a body of high conductivity material, are disposed one above the other to form vertical columns with series of side by side enclosures 3 between adjacent columns. Different fluids may be disposed in different vertical enclosures 3 depending on their location within the heat exchanger. For example in the region where the hot gas enters the heat exchanger the fluid may be mercury, while at the location where the hot gas leaves the heat exchanger the fluid may be water. The hot gas flow is countercurrent to the cold gas flow. In use the liquid in the bottom portion of each enclosure is vaporized by the hot gas flow, is then condensed in the upper portion by the cold gas flow, and thereafter returns by gravity to the bottom portion to be revaporized.
