Patent GB-654634-A (GB)
Title: Improvements in and relating to circular knitting machines
IPC: D04B9/26
Filed: 1946-11-18
Abstract: 654,634. Knitting- machines. BATA, NARODNI PODNIK. Nov. 18, 1946, No. 34153. Convention date, Aug. 7, 1942. [Class 74 (ii)] To enable split work fabric to be produced on a circular machine by continuous rotary knitting, the thread guides are maintained in an operative position during the whole of the knitting operation whilst the needles are selectively raised and lowered by cams to take their respective yarns. As described in connection with a machine for knitting a stocking having a foot portion formed with a reverse plated instep and a sole knitted of a single yarn, the instep and heel or sole needles 3, 2 have long and short butts 3a, 2a, respectively, and one or two medium butt needles 4 intervene between the two groups. A very short butt needle 5 is also provided intermediate the groups at one end only to enable the reverse plating yarns to be initially drawn at the commencement of the split work knitting. The thread guides mounted on eccentric bushes to ensure correct angle of feed to the needles, are held in an operative position by springs. A retractable needle cam 24 is positioned forward of a central cam 22 and at the commencement of split work knitting it is projected to engage all of the needles except the very short butt needle 5. Consequently all of the needles with the one exception are lowered, whereupon the instep needles having the long butts and the medium butt needles are immediately raised by a portion 51 of a lower cam 23, to bring them to a height at which they will take the reverse plating yarns 49, 50, the intermediate needle 5 having previously drawn these yarns to ensure the following needles eorrectly taking them. The portion 51 of the cam 23 being recessed permits the short butt needles to pass by it and they themselves are not raised until they have reached a position in which they can be raised clear of the reverse plating yarns. After receiving the reverse plating yarns 49, 50, the instep needles 3 are lowered by a retractable cam 21 which is positioned sufficiently well forward of a stitch cam 19 to prevent these needles from engaging the sole yarn 52. The medium butt needles 4 and the sole needles 2 having previously been raised do not engage the cam 21 and are directed into the path of the yarn 52 which they take and are then lowered by the stitch cam 19. The yarns extend across the needle cylinder as the fabric is produced and the usual latch finger arrangement is provided to engage the yarns as they are drawn across the cylinder prior to being taken again by the needles. The leg of the stocking is formed of reverse plated yarns 49, 50 and during the knitting of this portion the cams 21, 24 are removed from operation, knitting taking place in the normal manner. The cam 24 is operated by levers from a cam drum and is brought into operation for the knitting of the high splice and foot of the stocking. The thread guides are also selected by levers operated by cams on a drum. The heel and toe portions are formed of a single separate yarn.

Title: Manufacture of 3-amino-quinolines
IPC: H02K27/14
Filed: 1934-11-28
Abstract: 3-Aminoquinolines are obtained by heating under pressure with ammonia a 2-methyl-3-hydroxyquinoline, which may be substituted in the 4-position by carboxyl and in the 6-position by phenyl groups, if desired in the presence of ammonium sulphite.  According to examples, 2-methyl-3-hydroxyquinoline, 2-methyl-3-hydroxyquinoline-4-carboxylic acid, and 2-methyl-3-hydroxy-6-phenylquinoline-4-carboxylic acid (obtainable by the process described in Specification 450,842) are heated with aqueous ammonia to give the corresponding 2 - methyl - 3 - aminoquinoline derivatives, the carboxylic groups being split off; in the first-mentioned example a temperature of 220--225 DEG  C. is employed and the pressure rises to 75 atmospheres, but if ammonium sulphite is present a temperature of 180 DEG  C. and a pressure of 40 atmospheres are employed; in the second-mentioned example, if anhydrous ammonia is employed at a temperature of 200 DEG  C. the pressure rises to 173 atmospheres.  A sample has been furnished under Sect. 2 (5) of 2-phenyl-3-aminoquinoline obtained by heating 2-phenyl-3-hydroxyquinoline at 200--210 DEG  C. for 25 hours with concentrated ammonia, the pressure rising to 60 atmospheres.

Title: Reversible engine starter drive
IPC: F16D41/22
Filed: 1959-10-09
Abstract: 862,765. Engine turning gear. BENDIX CORPORATION. Oct. 9, 1959 [Oct. 23, 1958], No. 34302/59. Class 7(5). A reversible engine starter drive has a pinion 3 slidably journalled on a power shaft 1 for movement into and out of mesh with an engine gear 4 and drivable in rotation by a barrel member 5 having a clutch connection 6, 7, to the pinion 3, the structure for traversing the pinion including a tubular member 8 slidably journalled on the power shaft 1, having a splined connection with the barrel 5 and a pin 16 and V-shaped slot 17 connection with the shaft and yieldable means 13 for transmitting the longitudinal movement of the tubular member 8 to the barrel 5. As shown, the pinion 3 is connected to the barrel 5 by obtuse angled teeth 6, 7, allowing the pinion to be driven in either direction but allowing it to overrun when the engine starts. A spring 23 recessed in the pinion and a collar 21, held on shaft 1 by a spring clip 22 holds the pinion in the disengaged position wherein the pin 16 is held in the apex of the V-shaped slot in the tubular member 8, which is splined, by means of radial projections 11 on flange 9 and slot 12, to the barrel 5. In operation, rotation of the power shaft by electric motor 2 will cause the pin 16 to move the sleeve 8 to the right, carrying with it barrel 5 and pinion 3 compressing the spring 23 until the pinion 3 abuts collar 21. Further rotation causes axial pressure to be exerted yieldably by elastic member 13 compressing the pinion between the barrel 5 and collar 21, whereby the pinion is caused to rotate and crank the engine. To prevent the pinion being thrown back towards the engine after being demeshed the V-shaped slot at its apex is made approximately a right angle, and consequently causes little tendency for the parts 5, 9 and 3 to rebound, because of the normal reaction on the pin 16.

Title: Improvements in or relating to electro-mechanical filters
IPC: H03H9/125
Filed: 1956-11-09
Abstract: 853,054. Electromechanical filters. KOKUSAI DENKI KABUSHIKI KAISHA. Nov. 9, 1956 [Nov. 14, 1955], No. 34352/56. Class 40(8). An electromechanical filter is terminated by electrical resistances which match the mechanical image impedance of the filter. Fig. 1 shows one end (input or output) of a filter comprising an electrostrictive element c of circular section provided with supporting members d which form the electrodes. The internal capacitance of the element is tuned by means of a shunt inductor La and the filter terminated in a resistance Rt which matches the image impedance of the filter at mid-band frequency. In the case of a magnetostrictive transducer, the inductance of the transducing element is tuned by a series capacitance. The Specification gives methods for calculating the mechanical impedances of the filters from the mechanical constants and dimensions of the systems. In a modification, the internal capacitance or inductance of the transducer is used together with a reactance of opposite sign to form a low pass constant-K filter having a cutoff higher than the mid-band frequency.
