Title: Electro-fluidic transducer
IPC: F15C1/04
Filed: 1972-04-24
Abstract: 1385083 Fluid regulations ROBERT BOSCH GmbH 24 April 1972 [24 April 1971]  18898/72 Heading G3H [Also in Division H1]  An electro-fluidic transducer comprises an integrated component formed by three or more plate-like elements 1, 2, 3, Fig. 1, secured together as by solder or adhesive. The feed duct (21), Fig. 2 (not shown), of a fluidic amplifier receiving gaseous or liquid fluid via feed port 20, is formed in the central element I and extends longitudinally through a resiliently-mounted and laterally-movable armature 10 of an electromagnet which also includes a coil 9, soft-iron yokes 17' and permanent magnet 17. The fluid is discharged from the feed duct at the free end of the armature, across cavity 12 and into a pair of symmetricallyarranged outlet ducts (23, 24) communicating with outlet ports 25, 26. The cavity 12 may be connected to a reservoir or to atmosphere. Energization of the electromagnet causes lateral deflection of the armature in the appropriate direction according to the direction of the current consequent pressure differential at ports 25, 26. Teeth 15 on armature and co-operating recesses 16 render the magnetic pull independent of deflection but they may be omitted, especially if only digital output signals are required.

Title: Internal-combustion turbine plant
IPC: F02C3/30
Filed: 1946-06-25
Abstract: 613,663. Gas turbine plant. PEACOCK, J. B., and PEACOCK, H. E. June 25, 1946, No. 18944. [Class 110 (iii)] In a gas turbine plant of the kind in which a turbine drives a compressor which supplies air to a combustion chamber delivering combustion gas to the turbine, the steam raised in a water jacket surrounding the combustion chamber being used in the turbine, the passage from the combustion chamber to the turbine is cooled by a steam jacket which receives steam from the water jacket and supplies it to the turbine. As applied to the propulsion of a motor vehicle, the turbine is arranged with its shaft 38 vertical and drives the centrifugal compressor 12 and a main output shaft through bevel gearing. Water is supplied to a cooling jacket 21 surrounding the combustion chambers 17, as through a pipe 22, and the steam generated passes by way of a pipe 23, non- return valve 25 and annular chamber 24 to an annular cooling jacket 30 surrounding the combustion gas conduit 28, and mingles at 31 with the gas before it enters the turbine. After the working fluid has passed once through the outer blade row 32 and the inner blade row 33 in succession, it is re-directed to repeat the action once or more times, suitable transfer conduits 36 being provided for this purpose. There may be a third blade row inside the others. On starting, the non-return valve 25 is closed, and a portion of the compressor output is bled directly to the annular chamber 24 for cooling purposes. Sparking-plugs 19 may be used to initiate combustion. In a modification, the steam is not mixed with the gas, but flows separately through the turbine and then passes to a condenser, the condensate being returned through pipe 22.

The di- and tri-nuclear esters may be utilized in admixture with each other or with the analogous hydrocarbons in which the methylol acylate groups are absent.  Examples describe polyvinyl chloride compositions containing also Ba fatty acid salt/Cd phenate stabilizer, stearic acid epoxidized soybean oil, CaCO3, TiO2. Polymers otherwise specified are polyvinyl acetate, polyvinylidene chloride, vinyl chloride/acetate copolymer, polyvinylbutyral, butyl rubber, styrene-butadiene rubber and natural rubber; cellulose acetate and ethyl cellulose.ALSO:Hydrocarbons of formula <FORM:1103047/C4-C5/1> where n is 0-4 and R1 is a C1- 20 hydrocarbon radical (e.g. methyl), as well as the analogous tetranuclear compounds, may be isolated by fractional distillation of the mixtures (containing the corresponding methylol esters, see Division C2) which are formed by reacting CH2O with an aromatic hydrocarbon (e.g. toluene) and an aliphatic or aromatic carboxylic acid in equimolar proportions at an elevated temperature in presence of an acidic catalyst (e.g. H2SO4).ALSO:The invention comprises esters with C2- 21 carboxylic acids of monomethyloldiphenylmethane and monomethyloldibenzyl benzene, wherein each benzene nucleus may be substituted by one or more C1- 20 hydrocarbon radicals.  These compounds are prepared by reacting CH2O with a suitable aromatic hydrocarbon and an aliphatic or aromatic carboxylic acid in equimolar proportions at an elevated temperature in presence of an acidic catalyst (e.g. H2SO4).  In practice, the products are obtained in admixture with the corresponding di- and tri-nuclear hydrocarbons, and the mixtures are separated by fractional distillation.

Title: Improvements in or relating to fuel injection systems for internal combustion engines
IPC: F02D41/10
Filed: 1960-06-01
Abstract: 944,148. Transistor switching circuits. ROBERT BOSCH G.m.b.H. June 1, 1960 [June 26, 1959], No. 19366/60. Heading H3T. [Also in Divisions F1 and G1] The duration of fuel injection time for an I.C. engine is controlled by a transistor monostable relaxation oscillator in accordance with the degree of vacuum in the inlet manifold. The control circuit for the injection valves comprises two transistors 35, 36 connected as a relaxation oscillator with 36 normally conducting. A cam-operated switch 43 driven by the engine shaft produces a pulse on the base of transistor 35, causing transistors 35, 36 to change over, until 36 is again conducting after a delay determined by the inductance of coil 53 whose magnetic circuit includes an armature 54 movable by a rod 55 attached to a diaphragm sensitive to the degree of vacuum. Whilst transistor 36 is blocked, the change in potential at junction A blocks transistor 34 and allows transistors 37, 38, 39 to conduct, whereby winding 31 of valve 21 is energized and raises valve cone 101 to allow fuel to be fed into the cylinder. The valve 21 closes when transistor 36 reverts to its stable conducting condition. When the engine is rotating at higher speeds, the rate of change of flux in coil 53 produces an induced voltage which modifies the time during which transistor 35 is conducting. The pulse durations can also be altered, or switches S1, S2 associated with transistor 35.

Title: Improvements in alternating current modulation and demodulation systems
IPC: H03C1/52
Filed: 1937-07-15
Abstract: 498,895. Valve modulating circuits; valve circuits for wireless reception. WILLIAMS, F. C. July 15, 1937, No. 19648. Addition to 469,472. [Class 40 (v)] The parent invention, which is concerned with a modulation system comprising a pair of peak rectifiers passing carrier current on the same half-cycles, is modified by arranging that the rectifiers pass current alternately. In the Figure the carrier voltage is applied across circuit A, the ends of which are connected through diodes D1, D2, and their associated resistance-capacity load circuits to the point j. The output circuit O is connected from j to the centre point of circuit A. Modulation from transformer M is applied in series with a steady bias Eb in the same direction to both diodes. The diode load resistances r1, r2 are unequal so that the current pulses which flow on alternate half cycles, in the same direction, to the output have different values and a resultant modulated output appears in circuit O. In Fig. 2 (not shown), the output circuit is in two portions one of which is reversely connected and the modulation is applied in opposition to the diodes. In this case the diode loads may be equal. In Fig. 3 (not shown), the output circuit is connected in series with the rectifier circuits and receives the difference of their outputs ; again resistances r1 and r2 may be equal. These circuits are reversible to effect demodulation by feeding the signal to the circuit O, a locally generated carrier to circuit A and taking off the modulation from transformer M. Fig. 4 (not shown) is a modulation arrangement using triodes in place of diodes. Carrier and modulation are applied in opposite phase to the grids and the output is taken from a common circuit in the anodes in series with both branches. A steady biassing voltage is applied in opposition to the grids to ensure that the current pulses are unbalanced, or the secondary of the modulating transformer may be unbalanced for the same purpose. The load resistances may be equal or unequal. Fig. 5 (not shown) is an arrangement corresponding to that of Fig. 4 adapted for demodulation in which the circuits O and M are interchanged.
