Title: Improvements in or relating to apparatus for the production of aerosols
IPC: A01M13/00
Filed: 1954-08-16
Abstract: 751,575. Spray-producer. MOTAN GES. Aug. 16, 1954 [Aug. 14,'1953], No. 23799/54. Class 69 (3). Aerosol producing apparatus comprises a reso-jet tube into the pulsating exhaust gas column of which the dispersal fluid is fed and to which is acoustically coupled a second resonator of approximately the same resonant frequency. In Fig. 1 the reso-jet tube comprises a combustion chamber 1 and a throat 2 into which a nozzle 4 opens. The nozzle is fed from a pressurized tank 14 through a valve 15. An ignition cylinder 3 is fed from a carburetter 9 and, during starting, is also fed with air from a hand pump 12 through a non-return valve 10. When in operation air is drawn in through a non-return valve 6. The second resonator, which surrounds and extends beyond the throat 2, consists of a tube 18 of a length equal to a quarter wavelength of the resonant frequency of the reso-jet tube. The tube 18 has air inlets 19 at its rear end and this air is warmed by the throat 2 on its way to the zone d, which zone provides the coupling between the resonators. During operation the tank 14 is maintained under pressure by its connection with the chamber 1 through a pipe 16 and a one-way valve 17. In Fig. 2 the resonator tube 18a encloses the chamber 1 and the apparatus is shortened by forming a loop 20 in the reso-jet throat 2a. The loop passes through the tank 14a and heats the fluid therein. In Fig. 3 the second resonator has a chamber 22 surrounding the chamber 1, and a tube 23 of a length equal to one-eighth of the wavelength of the frequency of the system causes a preheating of the air drawn in through openings 19a. The resonator 18b is coupled to the reso-jet tube by a bore 21 in the wall of the throat 2. The resonant frequency of the system is altered by a tubular piece 24 or 25 arranged on the end of the resonator 18b.

Patent GB-651178-A (GB)
Title: Improvements in systems for regulating the frequency of a.c. generators
IPC: H02P9/42
Filed: 1948-09-10
Abstract: 651,178. Automatic control systems for alternators. BENDIX AVIATION CORPORATION. Sept. 10, 1948, No. 23869. Convention date, Oct. 30, 1947. [Class 38 (iv)] For regulating the frequency of an A.C. generator 16, the speed of the driving motor 11 is controlled by a carbon, pile regulator 21 operated by the output of a valve 35, the grid voltage of which is determined by the difference between.two signals, viz. (1) a voltage developed across a resistance 75 proportional to the amplitude and frequency of the A.C. generator voltage; and (2) a voltage across a resistance 55 proportional to the amplitude of the voltage. Signal voltage (1) is developed by a rectifier 73 supplied from the generator 16 through a tuned circuit 60 having a narrow response characteristic on either side of the desired frequency and peaked below that frequency. Signal voltage (2) is developed by a parallel circuit 18 including rectifier 53. The output circuit of the valve 35 includes an electromagnet 24 which operates the armature 22 of the carbon pile 21 against the action of a spring 23 to vary the pressure of the pile, the arrangement being such that the variations of frequency in A.C. generator 16 cause compensating action of the pile to vary the field 29 and thus the speed of the driving motor 11. To limit the operation of the control electromagnet 24, the voltage applied to the grid of valve 35 is limited by the action of a diode 90 and an anti-hunting circuit 81 is included in the grid circuit to develop an additional grid control for stabilizing the speed of the motor 11. A further control for limiting the flow of current in the armature of the motor comprises a bridge circuit including a diode 100, which provides an additional controlling bias for the valve 35. An electromagnet 25 is also included in circuit with the carbon pile and field coil 29 to stabilize the action of the electromagnet 24 and to compensate for fluctuations in the D.C. supply 14 for the motor. Negative temperature resistors 41, 42 are provided in the circuit of the main supply rectifier 44 to maintain constant the resistance of the electromagnet 24 irrespective of temperature.

Title: Improvements in or relating to transistor switching devices
IPC: H03K19/084
Filed: 1960-07-13
Abstract: 937,834. Transistor gating circuits. COMPAGNIE DES MACHINES BULL. July 13, 1960 [July 24, 1959], No. 24469/60. Class 40 (6). A transistor switching circuit includes a series of magnetic cores, the energizing windings of which are serially connected between the emitter of the switching transistor and a terminal of a constant voltage source, and a control transformer having a secondary winding connected across the base and emitter electrodes of the transistor. As described, application of three inputs to the " AND " gate 13 allows the potential at the point 15 to rise, and the simultaneous application of a negative pulse at terminal 16 induces a current into the transformer secondary, which saturates the baseemitter path of transistor Tr. A resulting emitter current flows through the windings 12, but is too small to cause any switching. A read pulse now applied to terminal 11 passes through the saturated transistor to energize the windings 12 of magnetic stores. After cessation of the pulses at 16, 11 the transistor remains saturated until desaturated by a pulse at terminal 17, and the inputs to the " AND " gate are removed.

Abstract: 1,114,503. Calculating apparatus. HONEY WELL Inc. 10 June, 1965 [19 June, 1964], No. 24649/65. Heading G4A. Data processing apparatus incorporates a unit comprising gating circuits which may be used for arithmetic operations on two operands or for logical operations at least one of which involves at least one further operand depending on input signals thereto. In a computer for performing both arithmetic and logic functions separate inputs to gating devices are activated according to the logical function to be performed and withholding of the logicalfunction-inducing inputs permits an arithmetic operation to be effected. In the illustrated embodiment the bits of two operands A, B are applied to three sets of gating devices (Figs. 2, 3, 4, not shown), together with bits V of an optional third operand and signals representing the logical functions to be performed on each bit, and the carries generated are applied to successive stages and the final sum applied to a sum decoder. In binary coded decimal arithmetic, carries between decades are added to the lowest position of the binary carry chain, a decimal carry decoder and carry store register being provided therefor. Subtraction is performed by complementary addition. The operation to be performed is determined by the signal on one of a plurality of lines applied to the carry chain from an operation code register which is supplied sequentially from a control memory. The control memory also addresses a main memory to obtain the operands A and B which are placed in A and B registers. After each operation, the address is incremented in the control memory and the next operand selected. The following logical functions are referred to: exclusive-or, logical substitution with masking and logical product. Binary and decimal addition and subtraction are referred to.
