Filed: 1929-09-27
Abstract: 333,143. Carpenter, R. E. H. Sept. 27, 192,9. Divided on 325,833. Thermionic amplifiers.-In an amplifier of the kind described in Specification 325,833 where use is made of the phase opposition between the input and output circuits of a thermionic valve to secure push-pull amplification, decoupling- means are employed to separate the valves producing the push-pull effect from the subsequent stages of amplification, so as to avoid back-coup. ling, which may either modify the frequencyresponse curve, of the system as a whole or cause persistent oscillation. As shown, the input voltage is applied to the grid of the valve A. From the plate resistance 3, a voltage is tapped off at an intermediate point 10 (to compensate for the amplification factor of the valve) and is applied to the grid of the valve B. The voltages in the leads 11, 12 are now equal in magnitude and opposite in phase with respect to the neutral point 13, and are applied to subsequent stages C - - F of amplification. According to the invention, a decoupling-resistance, 29, shunted by a condenser 30, separates the anode circuits of the valves A, B from the rest of the amplifier.

Patent GB-1011558-A (GB)
Title: Hydroxylamines and process for their manufacture
IPC: C07K7/64
Filed: 1963-02-18
Abstract: The invention comprises the trihydroxylamines cyclo - [(glycyl)3, (d - hydroxyornithyl)3] and cyclo - [(seryl)2, glycyl, (d  - hydroxyornithyl)3] which are obtained by removing the acyl groups from iron-free ferrichrome and iron-free ferrichrome A, respectively, by selective hydrolysis.  The acyl groups are acetic acid radicals in the case of ferrichrome and b -methylglutaconic acid radicals in the case of ferrichrome A, and may be removed by hydrolysis with a mineral acid, e.g. N-hydrochloric acid.  The products may be converted into acid addition salts with acids and may be acylated with carboxylic acid anhydrides to obtain tri-(O:N-diacyl) derivatives, which may be converted to the tri-(N-acyl) derivatives, by removal of the O-acyl groups with ammonia in methanol or with alcoholic potassium hydroxide. The tri-(O:N-diacyl) derivatives do not form iron complexes but the tri-(N-acyl) derivatives react with ferric salts to form iron complexes similar to ferrichrome and ferrichrome A.  The acyl derivatives are acidic and may be converted to metal salts.  The starting material may be obtained by removing iron from ferrichrome and ferrichrome A with 8-hydroxyquinoline in methanol. Examples are given.  The above compounds may be used in pharmaceutical and veterinary preparations in admixture with carriers, the compounds containing iron being growth-promoting substances and showing antagonism towards antibiotics of the sideromycin group; the corresponding iron-free compounds inhibit the deposition of ferriferous pigment in tissue and cause iron to be secreted, e.g. in haemachromatosis and haemosiderosis.
Patent GB-757121-A (GB)
Title: Thread-cutting device for lathes and like machine tools
IPC: B23G1/02
Filed: 1954-03-05
Abstract: 757,121. Lathe details. BAUCHART, A. March 5, 1954 [March 7, 1953; Oct. 30, 1953], No. 6518/54. Class 83 (3). A screw-thread-cutting attachment for lathes adapted to give automatic tool-relief when a stop on the attachment contacts a stop on the lathe bed, comprises a system of pivotally-interconnected togglelinks which, in conjunction with spring means, are forced out of alignment by contact of the stops to effect the relief or withdrawal of the tool. The base 1, Fis. 1. of the attachment is secured to the cross-slide of a screw-cutting lathe. A transverse-slide 2 moves across the base 1 for depth-of-cut adjustment of a tool carried in an angularly-adjustable holder. The tool 23, Fig. 2, may be adjusted to and from the work by a handle 7 connected to a worm 6 housed in the base 1. The worm rotates a pinion 5, also carried in the member 1, which in turn moves a rack 4 secured to the slide 2. The end of the worm opposite to the adjusting-handle has a reduced portion 11, Fig. 3, which bears against a roller 12 connected to a toggle-link arrangement 13, 15, anchored about a pivot 16. The end of the worm is maintained against the roller 12 by spring means between the slide 2 and the base 1. In the position shown, Fig. 3, the linkage is just off centre and held against an adjustable stopface 19 of a slidable rod 17. When the latter strikes a stop on the lathe-bed the linkage is thrown over to the broken-line position and the tool thus relieved for a return movement. This sudden movement is used to increase the depth of cut for the next traverse by a ratchet wheel 8 secured to the worm 6 which has a stirruppawl 28, Fig. 2, with an extension 29, Fig. 5, engaging an adjustable inclined-slot 30 in a member 31 carried by the tool-slide 2. When a further stop 18, Fig. 3, moves the linkage back to the original position the tool is therefore ready for a fresh cut. The roller 12 may be eccentric to the axis of the worm 6 and the contact-face of the reduced portion 11 provided with a cam portion to vary the increments of feed.

Title: Improvements in carburetting devices for internal combustion engines
IPC: F02M1/16
Filed: 1950-03-16
Abstract: 674,910. Carburetters. SOC. GENERALE DES CARBURATEURS ZENITH. March 16, 1950 [March 17, 1949], No. 6615/50. Class 7(iii) In a carburetter 6 for supplying an auxiliary mixture to an engine at starting and/or when running cold, the supply of fuel to a mixing chamber 16 is controlled by a valve 28 that is normally closed but is opened under the direct or indirect action of the engine suction, and a throttle valve 35 controlling a mixture outlet 24 connected with the induction pipe of the engine and downstream of a throttle valve of a main carburetter used for normal running, is closed when the engine has warmed up, by a manual or thermostatic control. An air inlet 17 is connected to the chamber and controlled by a valve 20 also actuated by the erigine suction. The manual control may comprise a cammed lever 40 connected by a spindle 36 to the valve which may be biassed to the closed position by a spring 45, Fig 2, and the thermostatic control may comprise a bimettalic blade 87 mounted in a housing 85 attached to the exhaust pipe 13 and which when warm allow a ball 88 to rest on a seating 90 to close conduits 83, 93 communicating the engine suction to a chamber 81 in which operates a spring-loaded piston 73, or a flexible diaphragm, Fig. 10 (not shown), connected to the valve, Fig. 8. The carburetter may be fed with a light fuel under pressure from reservoir or by the heavy fuel of the main carburetter through a conduit, that incorporates a valve absorbing part of. the pressure of the fuel delivered by a pump, connected between the fuel passage 25 and the constant level chamber or fuel supply conduit of the main carburetter. The valve 28 may be triangular in cross-section and applied by its own weight, which may be augmented by an auxiliary weight or a spring, to a seat 29 and against the fuel pressure; alternatively, the valve is seated by a spring and opened by a spring-loaded flexible diaphragm actuated by the engine suction, Fig. 7 (not shown). In modifications (a) the valve 35 is opened by a piston 73 subjected to suction through a conduit connected with the outlet 24 or the induction manifold, the ball 88 being inserted to allow atmospheric pressure to be communicated to the chamber 81 and to oppose the suction and close the valve, Fig. 11 (not shown), (b) the upper face of the piston is constantly subjected to suction and the lower face is acted upon by atmospheric pressure and, when the ball is unseated, to suction which overcomes the atmospheric pressure and allows the valve to be seated by the spring 75, Fig. 12 (not shown), and (c) both faces of the piston are subjected to suction from conduits connected to the outlet 24. and the ball closes a conduit communicating atmospheric pressure to the lower face of the piston which is lowered by the spring 75 to seat the valve, Fig. 13 (not shown).

Title: Improvements in or relating to direct reading micrometer screw gauges
IPC: G01B3/18
Filed: 1930-03-01
Abstract: 344,655. Linear-dimension gauges. MIZZY, A. D., 320, West 83rd Street, New York, U.S.A.-(Assignee of Favini, W. E. ; 114, 146th Street, South Ozone Park, Long Island, New York, U.S.A.) March 1, 1930, No. 6836. Convention date, March 2, 1929. [Class 106 (ii).] A direct reading micrometer comprises a screw and rotatable barrel which has axial graduations about its circumference numbered along a spiral having a pitch equal to the pitch of the screw said numbers being applied to the graduations in arithmetical progression the common difference of which is greater than one and the number of graduations being a non-multiple of the common difference. The usual bow 1 has an anvil 2 at one end and two concentric cylinders 3, 4 at the other end. In the space 5 between the cylinders works a graduated barrel 16 secured to the micrometer screw 7 which passes through the inner cylinder and ends in the rod 8. The outer end of the cylinder 3 carries a slotted nut 9 provided with a taper screw thread 11 on which is an adjusting nut 12 for taking up wear. The barrel 16 is provided with 25 axial lines 17 and the screw with 40 threads to the inch. The angular movement from one graduation to the next moves the rod 8 axially 1/1000". Alternate graduations are numbered continuously and in a spiral the pitch of which is equal to the pitch of the screw. It therefore requires two circuits of the spiral to place a numeral on each graduation. In the first circuit the numbers run 0, 2 .. 24, and in the second, 26, 28, &c., to take in the graduations not numbered in the first circuit. There is therefore 1/20" of axial distance available in which to place a numeral which is thus of a size suitable to be read. Other pitches of screws may be used providing there is an odd number of graduations on the barrel. Again, every third graduation may be numbered in which case there must be three circuits of the barrel before each of the 25 graduations receives a number. The invention may be applied to ordinary standard micrometer screw gauges by securing the graduated barrel to the ordinary thimble and clamping a second barrel to the frame such barrel projecting over the graduated one and bearing an index mark.
