Title: Electric drive for adjustment of presser foot in sewing machines
IPC: D05B69/28
Filed: 1962-10-19
Abstract: 946,911. Sewing machines. E. BECKER, and K. NOTZ. Oct. 19, 1962 [Oct. 30, 1961], No. 39573/62. Heading D1G. The presser bar of a sewing machine is displaced by means of an electric motor. The presser bar actuating motor may be switched on when the machine is started and switched off by means of a limit switch when the presser foot engages the work, the motor then being switched on to run in reverse when the machine is stopped, to be switched off by a further limit switch when the presser bar is fully raised. Preferably, the motor runs continuously, and the presser bar, which is spring-loaded, is raised via a magnetic clutch. As shown in Figs. 2 and 3 a clutch 3 contains a driving element coupled by a belt to an electric motor, and a driven element rigid with a shaft 6 which carries a worm meshing with a wormwheel 7 on a shaft 8 journalled in a gear-box 9. One end of shaft 8 carries a disc 10 having a crank-pin 11 engaged with a slidable rod 14 coupled by a chain link 17 to a presser bar lifting lever 5. The other end of shaft 8 carries a disc 12 having a cam lobe 13 adapted to engage in its uppermost and lowermost positions the actuating elements 20 and 21 of limit switches 18 and 19 respectively. The arrangement is thereby such that when the clutch is energized, shaft 8 rotates for half a revolution to either raise or lower the presser bar. In a modification disc 10 is replaced by a cam engaging one arm of a double-armed lever, the other arm of which is coupled to the presser bar lifting lever 5. It is stated that the motor operating the sewing machine can also operate the presser bar. As shown in Fig. 6, cam lobe 13 engages the upper element 20 and a brake coil 29 of clutch 3 is energized from a rectifier 31 via switch 18, the contacts 43, 44 of a switch 42 and the contacts 35, 36 of a switch 37. To start the machine a treadle 39 is depressed to actuate switch 42 for opening contacts 43, 44 and for closing contacts 45, 46 and 49, 50. Brake coil 29 is thereby de-energized and clutch coil 30 is energized, first via switch 18 and then via switch 19 when disc 12 rotates. When element 21 is actuated in the lowered position of the presser foot, coil 30 is de-energized, coil 29 is energized and a switch 55 is closed, via the contacts 49, 50 to energize a solenoid 56 for starting the machine. On release of treadle 39 the machine is stopped and disc 12 rotates till cam lobe 13 actuates element 20 when the presser bar is fully raised. Contacts 60, in series with contacts 43, 44, are opened when solenoid 56 is energized to prevent raising of the presser bar while the machine is operating. If switch 37 is actuated to close the contacts 34, 36, the presser bar is latted in an intermediate position when cam lobe 13 actuates a switch 59.

Title: Improvements in and relating to Magnetic Storage Systems
IPC: G11C7/00
Filed: 1966-09-09
Abstract: 1,157,401. Noise suppression in magnetic storage systems. INTERNATIONAL BUSINESS MACHINES CORP. 9 Sept., 1966 [14 Sept., 1965], No. 40357/66. Heading H3B. A two-element-per-bit storage system has a first sense line 50 for sensing magnetic rotation or switching in half the storage elements for a plurality of bit positions, a second sense line 52 for sensing magnetic rotation or switching in the other half of the storage elements for these bit positions, a two-input device 70 connected to lines 50, 52 for cancelling coincident signals of equal magnitude and the same polarity, and a bit drive line 30 arranged so as to generate coincident noise signals of equal magnitude and the same polarity in the sense lines. As shown, each row 12, 14, 16, 18 is divided into sections A, B, C, D arranged so that the signal propagation time in lines 30, 50, 52 is much greater through the sections than between adjacent sections. Word drive lines 40, 42, 44, 46 are also arranged so that equal noise signals are capacitively coupled to sense lines 50, 52 for cancellation in differential sense amplifier 70. Inductive and capacitive bit noise.-A bit pulse on line 30a induces a positive pulse on line 50 which reaches amplifier 70 four time units later, assuming a pulse takes one time unit to propagate through each section. After one time unit has elapsed the bit pulse begins to traverse the lower part of section A, in the opposite direction, inducing a negative pulse in line 52 which reaches amplifier 70 between time units four and six. The bit pulse then proceeds to section C where it induces a positive pulse on line 52 reaching amplifier 70 at time unit four and a negative pulse on line 50, arriving between time units four and six. As a result both the positive and negative components of noise on each line are cancelled by equal coincident pulses on the other line. Similar cancellation occurs for capacitively coupled bit noise. Adjacent bitline coupling noise.-In order to cancel noise induced in sense lines 50, 52 by a bit pulse in line 32 the lines may be rearranged (Fig. 5, not shown). In this case sense lines 50, 52 are crossed between sections B and C and, in order to maintain the previous relationship between the bit and sense lines of a row, the bit lines traverse the upper rows of sections C and D before the lower rows. The word bit and sense lines are terminated by matching impedances.

Filed: 1974-09-17
Abstract: 1486262 Combating take-all disease in cereals INSTITUT NATIONAL DE LA RECHERCHE AGRONOMIQUE 17 Sept 1974 [27 Sept 1973] 40427/74 Heading ASE [Also in Divisions A2 and C6] The cryptogamic "take-all" disease of cereals (wheat, barley, rice) produced by the fungus Ophiobolus graminis is countered by application of abnormal homogeneous strains of Ophiobolus graminis to the seed or soil. These are obtained by cultivating the fungus on an agar medium, which fungus is taken from cereals growing in an intensive rotationcropping field in the years following the maximum intensity of the disease, at which time the cereals show only very slight signs of attack, and selectively cultivating strains which exhibit a uniform growth pattern when viewed under light, as distinct from the normal strains which give concentric growth zones. The cells of the abnormal strain may be inoculated into the soil in the form of a culture on a finely divided supporting medium e.g. cereal grains which have been rendered incapable of germinating, straw, flour or cereal waste. Seeds may be protected from infection by providing them with an adhesive coating of methyl cellulose or polyvinyl pyrrolidone and then bringing the coated seeds into contact with the cells of the abnormal strain, living or dead. The protective effect of the abnormal strain on the growth of a wheat seed is illustrated by a test wherein the soil in box 11. Fig. 4. is inoculated with the abnormal strain at level 16 and a highly virulent strain at level 15 (c.f. boxes 12 and 10). In a further test, grains of barley which had been colonised by growth of the abnormal strain thereon, were exposed to infection by highly virulent strains inoculated into the soil at increasing depths, as shown in Fig. 3.

In Figs. 17 to 22 (not shown) the threads 21,22 are passed through the eyes (not shown) of needles 150,151 which are shed in unison and have a gap 153 between their ends.  The threads 23,24 pass through slots in two plates 165,180 that are shed in unison oppositely to the needles 150,151, the plate 180 being spring loaded to lag behind the plate 165.  In Fig. 17 the needles 150,151 are at the bottom and the plates at the top of their respective strokes.  In Fig. 19 the needles have started moving up and the plates down causing the threads to move to the opposite extremities of their slots and to grip onto the needle 150.  As the relative movement continues the thread 24 will pass through the needle gap 153 (Fig. 20) followed by the thread 23 (Fig. 21) so that the threads cross and change their respective positions so that, as movement continues, the needle passes through the threads 23,24 (Fig. 22) which are then at the opposite hand to Fig. 17. The groups of wefts are laid when the leno threads are at their extreme positions.
