Title: Improvements in or relating to electric amplifier circuits
IPC: H03F1/54
Filed: 1935-11-22
Abstract: 466,132. Valve circuits. SIEMENS & HALSKE AKT.-GES. Nov. 22, 1935, No. 32410. Convention date, Dec. 17, 1934. [Class 40 (v)] To prevent variations in gain of a thermionic amplifier due to variations of supply voltage, the circuit comprises compensating elements arranged so that the amplifier gain depends on their impedance, which in turn varies with the supply voltage in such manner as to counteract variation in gain. In Fig. 1, a resistance of uranium dioxide is connected across the supply terminals in series with a resistance W. Any increase in supply voltage will increase the gain of valve V but the impedance of H falls to compensate this; by virtue of the connection of anode resistance Ra and condensers C1 C2, H is in parallel with Vy for alternating currents. Alternatively as shown in Fig. 4, the series arrangement of W and H may be applied to a screen-grid valve by connecting their common point to the screen grid ; a non-linear element may be used for H in this case. In a further modification, H is directly connected across V but the operation is as shown in Fig. 1. The resistor H may in the simplest embodiment constitute the anode load resistance Ra, Fig. 3 (not shown).

Title: Improvements in or relating to Methods of Improving the Magnetic Properties of Steels for Magnetic Applications, and Products thus Obtained
IPC: C21D1/04
Filed: 1967-07-14
Abstract: 1,189,696. Making alloys; heat-treatment. COMPAGNIE DES ATELIERS ET FORGES DE LA LOIRE. July 14, 1967 [Aug. 9, 1966; June 19, 1967], No.32470/67. Headings C7A and C7D. Steel, particularly in the form of sheet, is coated with a thin layer of at least one element which increases resistivity, particularly Al, Si, Ge or Co, and this element is diffused into the steel while preserving the initial texture of the latter, the product then being treated at a temperature decreasing from 600‹ to 300‹ C. in a magnetic field the direction of which is parallel to the preferential direction of easy magnetization of the material. The coating element, which preferably forms up to 3% by weight of the steel, may be deposited by any known process such as vacuum deposition or decomposition of a volatile compound, while as exemplified diffusion is then effected by annealing in hydrogen at 900‹ C. for 3 hours. Alternatively coating and diffusion may be effected simultaneously by heating the steel for an appropriate time in a reducing atmosphere containing the element to be introduced e.g. for not more than 100 hours at 750‹ to 1050‹ C. The magnetic field treatment may be carried out either during cooling after diffusion, or as a separate step, in which case it may follow an intermediate heat-treatment of 1 to 3 minutes at 800‹ C. in a continuous furnace. The cooling rate in the magnetic field should be 5‹ to 300‹ C. per minute.

Title: Monogramming attachment for sewing machines
IPC: D05B3/24
Filed: 1971-07-12
Abstract: 1363727 Sewing SINGER CO 12 July 1971 [16 July 1970] 32562/71 Heading D1G A monogramming attachment uses a double sided cam disc 44 to guide the feed blade 20 which pivots about a screw 54 (Fig. 3) which passes through the slot 60 in the feed plate and is secured to the attachment frame 50 at 53 (Fig. 9). The sewing machine presser bar is accommodated in a seat 25, and the cam shaft 128 is rotated in steps via a lever arm 26 which embraces a needle clamp at 27. The lever arm 26 rotates the cam shaft 128 via a linkage arm 98 and a pawl arrangement 91 which operates on the serrated edge of a ratchet wheel 120 keyed to the cam shaft and which has a smooth edge segment 123 to prevent automatic repetition of the monogramming cycle. A manual cam indexing lever 28 is provided, as is a stitch density control lever 110 which has a lock nut 30 to clamp it in the desired position to enable the driving pawl to move the ratchet teeth the required distance on each oscillation. Operation. On a supporting plate 143, which is secured to but spaced from the plate 50, a follower arm 145 is pivoted at 144. A pin 146 on the arm follows the lower cam surface while another pin extends downwards through a slot 64 in the feed blade 20 to cause the feed blade to turn about the screw 54. The upper cam surface is tracked by a pin 42 on the hinged arm 41 of a slide plate 150, which is capable of limited longitudinal sliding movement relatively to the support plate 143 facilitated by screws or nuts 153, 154 passing through slots 151, 152 in the slide plate and held in plate 143. A pin 155 extending from the slide plate passes through the clearance slot 156 in plate 143 and through a slot 65 in plate 20 to cause plate 20 to slide with the slide plate. The monogramm stitch pattern is not usually a closed loop (e.g. for the letter "S") and the beginning and end do not coincide, so the smooth segment 123 on the ratchet wheel stops the feed plate moving at the end of the cycle. The work fabric is removed and the cam returned to the beginning of the cycle using finger lever 28. The hinged arm 41 is held against the interchangable cam by a spring 15 in the lid 13.

Title: Improvements in or relating to control apparatus for vehicles of the diesel-electric type
IPC: H02P9/00
Filed: 1932-11-17
Abstract: 399,038. Systems for transmitting mechanical power ; speed governors. SULZER FRERES SOC. ANON., Winterthur, Switzerland. Nov. 17, .1932, No. 32573. Convention date, Dec. 4, 1931. [Class 38 (iv).] In a Diesel electric vehicle the starter resistance 6 in the field of the generator 2 is also in series with a variable resistance 7 which is controlled through a pneumatic relay 14, 15 by a governor 11 geared to the prime mover shaft so that the resistance 7 remains shortcircuited until the vehicle first reaches the speed at which the prime mover is fully loaded by the actuation of the starter 10, pressure fluid then being admitted, by the downward movement of the governor sleeve, to the underside of the piston 15 so as to insert the resistance 7 in the generator field circuit. Control is thereafter effected automatically in accordance with the engine speed. The resistance 7 may be constituted by the starter resistance 6 in which case any well-known mechanical interconnection between the members 10, 17, e.g. a differential mechanism, may be used. A relay responsive to the generator load current may be connected so as to control the fluid connection to the upper side of the piston 15 so as to limit the tractive effort to the value below which wheel slip occurs, and an additional governor driven from the axle of the vehicle may be arranged to control the position of the stationary pivot of the governor lever 13, or a separate valve controlling fluid admission to the cylinder 16, or a separate resistance in the excitation circuit so as to limit the maximum speed of the vehicle. The vehicle speed may be maintained below the maximum value by retaining some of the starter resistance 6 in the excitation circuit. The value of the " full load " at which it is desired to work the Diesel engine may be adjusted by adjusting the spring tension of the governor 11 or the cut-off positions of the piston valve 14 controlling the supply to the cylinder 16. In a modification, Fig. 3, an isodromic return or resetting connection is provided between the rod of the piston 15 and the lever 13 so as to return the lever 13 to its normal position irrespective of the new position of the arm 17. The lever 13 is pivotally connected to an arm 28 to a median point of which the operating rod of the valve 14 is connected, the farther end of the rod 28 being connected to a piston 23 spring-anchored in a cylinder 21 which is in communication with a cylinder 20 housing a piston 22 provided with a leak aperture 25 and connected to a pivoted lever 24 secured at its farther end to the rod of the piston 15. Engine speed variations actuate the valve 14 which causes movement of the piston 15 to adjust the generator excitation, at the same time transmitting a movement through the device 20, 21 to close the valve 14, the time lag, introduced by the leak 25, in the return of this motion, being such that the engine speed will have responded to the control and have moved the lever 13 to maintain the valve 14 closed.
