Title: Improvements in Driving Couplings for Magneto-electric Machines.
IPC: F16D5/00
Filed: 1918-04-12
Abstract: 126,426. M-L Magneto Syndicate, and Hulse, C. E. April 12, 1918. Magnetos, driving. - A magneto is driven through a form of coupling in which a driven disk A keyed on the magneto shaft B is arrested during part of each revolution and then released and rotated by a helical spring E to produce an ignition spark at low speeds. The disk A is provided with a boss A<1> which forms a bearing for a driving member C, the members A, C being coupled together by the spring E. Two weighted levers D are pivoted on the disk A and can turn upon their pivots D<1> so that the short arm D<2> protrudes from the coupling; gaps C<3> are provided in the flange C<2> for the purpose. Projections A<2> on the disk A extend into the gaps C<3> to allow a certain amount of angular movement of the members A, C. The member C is coupled to the engine either by means of the pins G, or by a chain-wheel mounted upon the flange C<2>. As the member C is rotated slowly in the direction of the arrow X, the short arm D<2> of one of the levers engages a fixed abutment F, arresting the disk A; continued rotation of the member C stresses the spring E until the inclined edge C<4> of the gap C<3> makes contact with the arm D<2> and tilts the latter out of engagement with the abutment F, thereby releasing the spring and accelerating the magneto armature. When a predetermined speed of rotation is exceeded, the longer arms of the lever D are thrown outwardly by centrifugal force and move the arms D<2> from contact with the abutment. For giving one spark only per revolution, a single lever is employed and is balanced by a counterweight. As an alternative to the inclined edges C<4>, cam swells C<6> on the boss of the member C. may engage the long arms of the levers D. The stop F is carried by a bridge F<1> secured to the magneto. The support may be constructed initially with two abutments F, F<2>, one for right-handed and the other for left-handed rotation of the magneto, the one not required being subsequently removed. For the direction of rotation opposed to the arrow X, the abutment F<2> is used and the levers D are placed on their pivot pins so as to point to this abutment, the position of the cam edge C' being correspondingly altered.

IPC: C07C51/56
Filed: 1916-05-08
Abstract: 100,450. Dreyfus, H. April 19, 1915, [Convention date]. Organic acid anhydrides.-Acetic anhydride is prepared by treating acetates, such as sodium acetate, with the chlorides of sulphur S Cl2, S2 Cl2, or S Cl3 in such proportions that six atoms of chlorine are present for each eight acetyl radicals; the process is carried out by introducing the sulphur chloride at a low temperature into the dry acetate in a form presenting a large surface, in the presence of a diluent, for example acetic anhydride. The product is freed from sulphur by treatment with a suitable metal, such as copper or lead, or an oxide or salt thereof, or by treatment with oxidizing-agents, such as permanganates, nitric acid, or nitrates. The Specification as open to inspection under Sect. 91 (3) (a) states also that the process above described may be applied in the production of other acid anhydrides, and is not limited to the chlorides of sulphur specified above nor to operating at a low temperature in the presence of a diluent. This subject-matter does not appear in the Specification as accepted.

Abstract: 871,927. Protective arrangements. ENGLISH ELECTRIC CO. Ltd. Feb. 26, 1959 [Feb. 28, 1958], No. 6606/58. Class 38 (4). [Also in Group XL (b)] An electrical A.C. impedance network for use in a synchronizing or measuring circuit whereby the power flow is unrestricted in one direction but suppressed in the reverse direction comprises an autotransformer 25a, 25b, resistors 19a, 19b and rectifiers 23a, 23b, 24a, 24b. A first voltage applied to terminals 20a, 20b will cause a current to flow in a load connected across terminals 21a, 21b and halfwaves of circulating current to flow in resistors 19a, 19b, which circulating current is opposed by a second voltage across terminals 21a, 21b. When the second voltage exceeds one half of the first rectifiers 23a, 23b, block and an impedance of one of resistors 19a, 19b is presented to the difference between the voltages. In another mode of operation, a voltage applied to terminals 20a, 20b and a load connected across terminals 21a, 21b causes a half-wave circulating current through resistors 19a, 19b as before. Provided that the load current is not greater than the circulating current alone, the current through resistors 19a, 19b will be constant. For greater values of load current the voltage across resistors 19a, 19b will increase and rectifiers 24a, 24b will block. Isolating transformers may be connected to the terminals 20a, 20b, 21a, 21b.

Abstract: 1282832 Image pick-up tube; semi-conductor devices TRW Inc 15 March 1971 6843/71 Headings HID and HlK The screen of an image pick-up tube comprises a transparent substrate 12, Fig. 2, carrying a layer 14 of semi-conductor material of first conductivity type, a sputter-deposited film 24 of semi-conductor material of opposite conductivity type, optionally a second sputter-deposited film 26 of the first conductivity type, and isolated conductive electrodes 25 across which the electron beam is scanned. The substrate is preferably sapphire optically polished on both surfaces and may form the faceplate of the tube. The layer 14 is preferably epitaxially deposited N-type silicon and may be about one micron thick, that is less than the mean free path of carriers generated at surface 13; at its edge there is an N + region 15 forming a contact base for a gold output electrode 16. The sputtered layers 24 and 26 of P-type silicon and N-type silicon respectively have a very large sheet resistance, and in fact comprise a large number of semiconductive areas each separated by an insulating barrier of silicon dioxide. The electrodes 25 are 10 to 100 A in size so that the resolution is determined by the beam diameter rather than by the target construction. The electrodes may be of gold either evaporated through a mask or deposited by a process involving agglomeration during vacuum deposition; if the latter process is used, indium and tin are possible alternative materials. The layer 26 may be omitted (Fig. 1, not shown) leaving an array of diodes instead of triodes.

Abstract: 1,086,146. Automatic speed control. BROOKHIRST IGRANIC Ltd. Feb. 18, 1965 [March 6, 1964] No. 7039/65. Heading G3R. [Also in Division H3] A variable frequency signal, for example derived from a generator 2 coupled to a motor, is fed to a Wien Bridge circuit 4 tuned to give no output at terminal OT at some predetermined frequency. Deviation of the frequency of generator 2 from the predetermined value produces an A. C. signal at OT, the phase of which depends on whether the signal is above or below the predetermined frequency. This signal, V out, is fed to a phase sensitive detector comprising transistores T1, T2 which are switched by a further output fed from generator 2 via phase shift capacitor C8 to the base of T2. Transistor T1 thus shunts alternate half cycles of the signal V out to produce at terminal 12 a D. C. signal the polarity of which depends on whether the generator signal is above or below the predetermined frequency, and the magnitude of which depends on the frequency deviation. This signal may be used to adjust the motor speed.

Title: Process of sealing cellulose ether sheet materials and articles produced thereby
IPC: B29C65/48
Filed: 1945-03-21
Abstract: A sheet of an alkali-soluble water-insoluble cellulose ether is joined to a contiguous surface of the same or another material by applying an aqueous solution of an organic or inorganic alkali to the surface of the cellulose ether sheet and then bringing the treated surface into contact with another surface.  Pressure may be applied during the sealing.  The cellulose ether sheet may be a film, foil or like nonfibrous sheet, and it may be used as a wrapping material or for making containers of any desired shape, the seams being sealed by applying the alkali to the overlapping sections.  Thus, a strip of the material may be formed into a tube with a longitudinal seam, or it may be wrapped round a mandrel to form a tube with a spiral seam. Tubes suitable for use as drinking straws may be obtained.  A strip of the material may be used for wrapping a number of small articles such as medicinal tablets, and transverse seals between the individual articles as well as a longitudinal seam may be formed using an alkali as bonding agents.  Bags and other shaped wrappers or containers may be formed.  The process is also applicable for sealing or laminating sheets of alkali-soluble cellulose ether to a similar or different material, e.g. of regenerated cellulose film, rayon fabric, paper, wood, wood-pulp, synthetic resin, organic solvent-soluble cellulose derivative or metal.  The bonding agent may be an aqueous solution of caustic soda, caustic potash, lithium hydroxide, sodium zincate, sodium stannate, tetramethyl - ammonium hydroxide, tribenzyl methyl - ammonium hydroxide, tetrabenzyl-ammonium hydroxide, mono-, di- or tri-methylamine, or diethylamine.  The alkali-soluble water-insoluble cellulose ether may be an alkyl, hydroxy-alkyl, or carboxy-alkyl ether or it may be a cellulose ether xanthate or cellulose xanthate ether.  The alkali solution may contain 2 to 10 per cent of a strong alkali and, if desired, it may also contain up to 10 per cent of a cellulose ether.
