Title: Bomb dropping device for air crafts
IPC: B64D1/04
Filed: 1927-04-02
Abstract: 284,107. Boos, O. J. April 2, 1927. Ordnance, pneumatic.-A pneumatic piston is provided to impart a rearward impulse to a bomb at the moment of its release from an aircraft, whereby the effect of the forward speed of the aircraft is counteracted and the bomb is made to fall substantially vertically. As shown in Fig. 4, the bomb B has a winged tail b provided with shoulders c, which rest on a seat 10 and are embraced by a pair of grippers 11. These grippers are confined by rails 4 and the seat 10 is mounted on rails 2 and is attached to the rear end of the rod 9 of the piston 8 of a cylinder 7. The ends of the cylinder are connected by pipes 19, 25 to a distributing valve 17 supplied with compressed air from a tank 15 through a regulating valve 16. Normally, the valve 17 connects the pipe 25 to exhaust and the pipe 19 to the compressed air supply, thereby holding the piston 8 in the forward position shown. To drop the bomb, a trigger 21 is pulled, releasing the lever 23 of the valve 17, which is then turned by a spring 24. The valve 17 now supplies air to the pipe 25 and connects the pipe 19 to exhaust. The piston 8 and the bomb B are thrust backwards until the grippers 11 pass beyond the rails 4 and are thrown open by a wedge 6 in conjunction with a spring, thereby dropping the bomb. While this is taking place, compressed air passes through a pipe 27 to an expansion chamber 27a and thence to a cylinder 28. When the pressure in the cylinder 28 has risen sufficiently, it drives a piston 29 coupled by a link 30 to the lever 23 of the valve 17, which is thus automatically returned to the original position. The regulating valve 16 is connected by a link 16<a> to a pointer 16<b>, which is set to graduations 33 according to the reading of a speed indicator 34. In a modification, the bomb is held in a horizontal position between pivoted end grippers.

Title: Improvements in inverters for producing high frequency alternating current
IPC: H02M7/44
Filed: 1935-03-25
Abstract: 454,489. Converting. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London. March 25, 1935, No. 9269. Convention date, March 23, 1934. [Class 38 (ii)] In a parallel type inverter operating at high frequencies, the period available for deionization is increased by using at least two groups of valves connected in parallel and arranging the grid excitation so that successive half waves of the same sign of the A.C. produced pass through different valves. In one arrangement, Fig. 1, pairs of valves 11, 12 and 21, 22 associated with chokes 13, 23 are connected to opposite ends of the primary 31 of a transformer, the secondary 32 of which feeds the load circuit, a centre tap on the primary forming the positive input terminal. The grids of each pair of valves are connected through resistances to the anodes of the other pair, and are also connected through condensers and resistances to a tertiary winding 33 on the main transformer, the centre point of which is connected through a source of negative bias 6 to the cathodes. The resultant grid potential is such that each valve becomes conductive in the correct sequence for one half cycle in every two cycles of the output frequency. Commutation of the current between pairs of valves is effected by a condenser 4 connected across the primary of the main transformer. Condensers may also be connected across the chokes 13, 23. Fig. 2 shows a modification in which one component of the grid excitation is derived from an external source. In this arrangement the two sets of parallel connected anodes 11, 12 and 21, 22 co-operate with a single cathode. One set of grids is energized by a voltage resulting from a source of negative bias 60, a tertiary winding 33 on the main transformer, and a winding 92 of a two phase generator of half the inverter operating frequency. The other set of grids is energized by a voltage resulting from the source of negative bias 60, the winding 33, and the other phase winding 91 of the two phase generator. Thus, each grid receives a potential which only reaches the ignition value once in every two cycles of the operating frequency of the inverter and the sequence is such that the valves conduct in succession.

Abstract: 1,082,881. Electric position indication. KEUFFEL & ESSER CO. March 4, 1966 [March 8, 1965], No. 9595/66. Heading G4H. The position of a movable member is indicated by a magnetic tape having a scale recorded along its length for co-operation with a magnetic head on the movable member. In the form of Fig. 1 a pointer is carried over a chart 11 by a slider 22 moving on rails 20 which are themselves carried by sliders 14, 15 on rails 12, 13. Magnetic tapes are let into the rails 20 and 12 to be read by heads on the sliders and produce the signals. The coding on the tape, Fig. 4, includes four binary bits 1, 2, 4, 8 repeatedly indicating values 1-9, and three binary bits A, B, C indicating powers of ten. The reading heads are connected through a logical circuit to an indicator panel having lamps arranged in five columns. There is a separate panel for X, Y and Z movements. In the first nine positions the binary equivalents of values 1-9 are displayed in turn in the right-hand column of lamps. In the tenth position a signal in the C channel causes the end column to go blank to indicate digit 0 and the signal in the C channel indicates ten to the power 1. A " 1 " in the 1, 2, 4, 8 channels causes the bottom lamp of the second column to be lit, and it stays lit for the next nine digits, 11- 19. At 20 the end column again goes blank, the next column is cancelled and a 2 signal on the 1, 2, 4, 8 channels is entered into the second column, lighting the second lamp. At 100 the " power 2 " signal on channel B causes the " 1 " on the digit channels to be entered in the third column. The tens digit " 1 " is entered in the bottom lamp of the second column at 110 and this process continues for the rest of the scale. During descending movement one is subtracted from the values in all the columns except the right-hand column.

Title: Non-linear optical amplification
Inventor: O'MAHONY MICHAEL JOHN
IPC: H01S5/042
Filed: 1996-07-25
Abstract: An optical amplifier having a saturable absorption region is operated below the lasing threshold for the device. Non-linear effects and bistability are observable at temperatures above room temperature. A selected input wavelength  lambda i within the gain spectrum of the device is amplified and an output at the same wavelength  lambda i is produced. This is in contrast to the normal operation at threshold, where there is a wavelength shift to the lasing wavelength and, depending on the laser used for the saturable absorption device, the output may be multimode for a monomode input. Best gain is achieved by tuning the input wavelength to a peak of a Fabry-Perot mode in the gain spectrum for the amplifier. The amplifier may be used as a wavelength controlled optical switch, when operated bistably, or as a regenerative amplifier when operated in the non-linear region without hysteresis effects.
