Abstract: 1,218,148. Holography. INTERNATIONAL BUSINESS MACHINES CORP. April 11, 1969 [July 12, 1968], No. 18705/69. Heading G2J. Information, e.g. of a ship 10, is recorded in a storage medium 11, e.g. a photographic plate, by interfering an information bearing beam 12 of radiation with a plurality of reference beams 13 of coherent radiation in the medium to form holograms, the reference beams being collinear with respect to one another and interfering in time sequence with different portions of the information bearing beam. Preferably a laser beam is split into three portions 16, 17, 18, of which 17, 18 are directed on to the object 10 and then to recording medium 11. The object 10 has dimensions greater than the coherence length of the radiation. The reference portion 16 is divided at 30 into two ports 33, 34 polarized at right angles to each other, the port 34 passing through a quartz crystal for example, to retard it relative to 33 and give a path length difference between portions 33, 34 not greater than the coherence length of the radiation. The portions 33, 34 are made collinear by a crystal 31 to give two reference beams 13 which will respectively interfere with different portions of the information beam 12, each portion of the information beam representing a part of the object having dimensions not exceeding the coherence length of the light. The reference beams may interfere with the information beam from the same or the opposite side of recording medium 11. If desired any number of reference beams may be used provided that the path length between successive beams does not exceed the coherence length of the radiation. The information may be read out of medium 11 after its processing by a reference beam collinear with reference beams 13.

Filed: 1966-04-29
Abstract: 1,150,603. Electrophonic musical instruments. NIPPON COLUMBIA K.K. 29 April, 1966 [30 April, 1965], No. 18872/66. Heading G5J. An automatic rhythm player or " side man " comprises a pulse oscillator the output pulses of which successively energize the inputs of a translator (e.g. a diode matrix), the outputs of which control sound generators corresponding to different instruments. As described eight pulses per bar produced by an oscillator 1 are applied to a circuit 2 comprising cascaded toggles F 1  to F 3  and AND gates G 1  to G 8  which sequentially energize input lines L 1  to L 8  of a diode matrix. Output lines S 1  to S 4  of the matrix are connected to sound generators M 1  to M 4  each corresponding to a different instrument and operating a common loudspeaker 6. The locations of the diodes determine which tone generators function during each time interval. Switches 7 1  to 7 4  can be opened to disable selected generators. To produce a more complex rhythm which repeats every two bars, a toggle Fx tripped by the pulses applied to line L 1  enables AND gates A and A<SP>1</SP> alternately in successive bars. Thus during alternate bars the output line S 1  is disconnected from the generator M 1  and an additional output line S 1 <SP>1</SP> with a different arrangement of diodes is used to control this generator. In a modification (Fig. 5, not shown) a number of output lines similar to S 1  and S 1 <SP>1</SP> are provided for each generator and in place of the toggle Fx and AND gates A and A<SP>1</SP> selector switches are used. In a further modification (Fig. 3, not shown) the diode matrix has sixteen input lines, and sixteen pulses (i.e. sixteen time intervals) per bar are used.

Title: Microwave energy oven seal
IPC: H05B6/76
Filed: 1975-05-07
Abstract: Between the door (20) and the housing walls, the microwave oven has a microwave trap with a propagation path (68 to 74). The latter surrounds an inductor seal (22) which has a region of low impedance (which presents a higher impedance value in the case of its transformation to the inlet point) at a distance equal to half a wavelength from the inlet point of the microwaves into the trap or an integral multiple thereof. In order that low production costs and relaxation of the tolerance limits are made possible and, at the same time, in order that safety with respect to escaping energy can be improved, a further inductor seal (104), likewise having a region of low impedance, is provided between the housing walls and the door, in series with the first inductor seal, in the region of the propagation path. The mean distance between this further inductor seal and the outer edge of the door and the first inductor seal (22) is in this case selected such that the second region of low impedance to the outer edge of the door and to the inlet point (68) of the microwaves into the propagation path (68 to 74) is transformed to a higher impedance. This results in two-stage reduction of the energy escaping from the oven space. <IMAGE>
