A machine for sewing darts comprises a work-support surface, a movable bar engageable with said surface for feeding work therealong, a folding bar movable over said surface and under the raised feeding bar, and a bar provided with spikes for holding the work at the rear of the feeding bar and for releasing the work on retraction of the folding bar and lowering of the feeding bar. A sewing machine 3, mounted on a table top 2, is provided with an elongated workfeeding bar 4 having a roughened work-engaging under surface and being formed in its upper surface with a longitudinal groove 4<SP>1</SP> engaged by a fixed guide pin 11 adjacent the stitching point. Bar 4 is connected to a slide 5 movable on a guide rail 7 by means of gearing 6. Bar 4 is raised and lowered by an air motor 8 via a bell crank lever 9. A work-folding bar 13 extends from a work-supporting plate 12 carried by rods 12<SP>1</SP> slidable in a structure mounted under table top 2 for pivotal movement co-axial with the sewing machine needle by means of a handle 12<SP>11</SP> movable over a scale 16 for varying the angular position of bar 13 relative to the feeding bar 4. An air motor coupled to rods 12<SP>1</SP> serves to move bar 13 over table top 2 and under the raised feeding bar 4. Work located on plate 12 by a template 38 held in position by magnets 39 hangs over the edge of bar 13 and is folded upon movement of the latter. Bar 13 first passes under an angle bar 17, carried by a structure 18, 20 and lowered by an air motor 21 against the bias of springs 19 to a position in which a resilient blade carried by bar17 engages the work on bar 13. When the latter is fully advanced, a bar 23 is lowered by an air motor 25 against the bias of springs 24, whereby the work is held in position by spikes 22 which are carried by bar 23 and which pass through notches 13<SP>1</SP> formed in bar 13. A presser foot (27), pivoted to bar 4 adjacent the stitching point, is simultaneously lowered by an air motor 28. Bar 13 then retracts, bar 4 is lowered, bars 17 and 23 are raised and finally, before stitching commences, the work still resting on plate 12 is removed therefrom by the downward movement of a rod 37 carried by a bell crank lever 35 actuated by an air motor 36. A strip (33) which may be incorporated in the seam is led to the stitching point by a guide tube (31) extending downwardly from the undersurface of the throat plate, the strip being severed at the end of the operation by a knife (34). The work may be trimmed in the line of feed by a knife (29).

Abstract: 1,157,127. Computers; printers. GENERAL ELECTRIC INFORMATION SYSTEMS ITALIA S.p.A. 11 Oct., 1966 [14 Oct., 1965], No. 45346/66. Headings G4A and G4H. The arithmetic unit and main memory of a computer jointly command elementary operations of a peripheral input/output device. The computer of Fig. 1 includes the following units connected as shown: main memory MM, instruction address register VI, operand address registers VA, VE, incrementer/decrementer CV, further registers RO, RA, arithmetic unit UA, a microprogramme control matrix ML of NOR gates, operand message length register LO (storing one or two lengths) with decrementer CL, and registers FO, SO, RE. Up to two input/ output operations may take place concurrently in interleaved fashion, using registers VA, VE respectively to specify the locations in memory MM which are involved. Each input/output operation is set up by one or two instructions from memory (in the case of two, the first addresses the second). Input/output operations with " non-integrated " peripheral units use the register RE for buffering the data transmitted (in either direction) and commands for the peripheral unit from the programme. " Integrated " peripheral units can receive commands from the register RE but send data on respective channels E1S, E1L direct to register RO. Message length is controlled by the programme presetting register LO in the " non-integrated " case and by the peripheral unit in the " integrated " case. In the case of an " integrated " peripheral unit which is a card reader, clock signals controlling data transfer come from the reader. In the case of an " integrated " peripheral unit which is a high-speed printer, as each character comes into print position a representation of it from the printer is stored in a first position in a line in the main memory MM, the first such character also being stored in a second position in the memory line. The other positions hold the characters required in the printed line. The contents of the first position are compared with these other positions in turn in the arithmetic unit UA to produce print commands CS, and with the second position to indicate completion of a revolution of the typewheels (and therefore completion of the printed line).

Abstract: 1,055,309. Automatic weight control. UNEXCELLED CHEMICAL CORPORATION. Nov. 22, 1963 [Nov. 27, 1962], No.46245/63. Heading G3R. [Also in Division H3] In a system for regulating the weight of a product 16 which is loaded on a conveyer 18 by a dispenser 20, two magnetic cores 34, 36 of rectangular hysteresis material are allotted to underweight and overweight corrections respectively, the magnetic state of the appropriate core being set below the saturation limit to an extent determined by a pulse of controlled duration whose constant amplitude represents the actual weight of the product, and the core being reset to saturation by a constant potential, the duration of the output pulse produced during resetting being determined by the previous input pulse amplitude and hence to the weight discrepancy of the product. As shown the product is weighed by displacing the core 24 of a variable transformer 22 connected between an oscillator and an amplifier and rectifier, a negative voltage output of 4 volts, for example, indicating the correct weight, and voltages between -1 to -4v and -4 to -7v indicating the degree of overweight or underweight respectively. If the weight is correct, neither of transistors 66, 68 respectively responsive to underweight and overweight potentials become conductive. Each transistor is connected to a reference potential of -4v at a potential divider 50, 52, and if the weight is incorrect the appropriate transistor for over or underweight applies the weight error voltage to an input winding 38, 40 of the respective core 34, 36. Partial switching of this core takes place for a controlled duration when a timer 63 opens transistor gates 56, 58, the current direction through the input winding of the unselected core being such as to drive the core flux further into saturation. Subsequently the partially switched core is reset by opening a transistor gate which applies correction potentials from sources 90, 92 to core output windings 44, 46, an output pulse being applied to either the heavy or light input of a servo 14 which controls the dispenser 20 during the resetting time of a partially switched core.
