Title: Improvements in or relating to the measurement of the time occupied by sound in travelling to and from a reflector
IPC: G01S15/10
Filed: 1922-01-19
Abstract: 174,355. Blondel, A. E. Jan. 19, 1922. Short-time movements. - Comprises apparatus for timing the short interval between an initial sound and its echo, and consists in means for measuring the distance travelled by a simultaneous disturbance propagated through an acoustic system. The echo, heard in one telephone T', is compared with a sound produced in a second telephone T by a disturbance which has travelled at a known speed over a measured section AM1, AM2 . . or AM, of a " propagator " or sound-conveying system AB, adjustments being made until the sounds in the two telephones are heard simultaneously. In one form of the invention (not shown), the " propagator " AB comprises a spiral tube filled with air, hydrogen, water, alcohol, ether, or the like, and flared at the far end to prevent reflection of the disturbance travelling in it. In a further modification, the propagator AB comprises an artificial line made up of inductances and capacities along which an electric disturbance travels at a low rate. In further modifications, the propagator AB may comprise a rod, wire, cord, or metallic strip capable of transmitting longitudinal, transverse, or rotational disturbances. Thus in the form shown in Fig. 12, a cord H is attached at its lower end to a pivoted bracket 35, which receives a blow from the striker Q<1>. The disturbance initiated by the striker Q<1> travels up the wire, in one form, until it breaks contact at l<1> with a sliding contact-maker, or, in another form, until it affects a microphone m. In either case, a sound is produced in the telephone T, which is protected from any sound due to the reflexion of the disturbance by a short-circuit or disconnection applied by the time-lag switch 38, the reflection itself being checked by a magnet 36. The sliding contact-maker or the microphone is adjusted until the sound produced in the telephone T coincides with the echo of the initial sound. Instead of a cord H, a flat steel or bronze strip, loaded for transmitting torsional disturbances, may be used. When such a disturbance has travelled an adjustable distance along the strip, it causes a sound in the telephone bv affecting a microphone or causing the strip to make or break an electric circuit or to break a magnetic circuit, means being described for preventing any subsequent reflected disturbance from having a similar effect. Reflection is checked by arranging a pawl and ratchet at the far end of the strip, or the telephone may be put out of action by the disturbance reaching that point. The steel strip may be replaced by a tube cut into a helix, or a loaded helical spring, or a series of coaxial discs connected by springs, or a ladder comprising two wires connected by cross-pieces.

Filed: 1964-01-15
Abstract: 1,030,091. Socket housings. PRESSAC Ltd. Jan. 7, 1965 [Jan. 15, 1964], No. 1755/64. Heading H2E. Open ended tubular insulating housings 1 (Fig. 2) are made more resilient by making two parallel slits 3 in the wall of each housing, to form a strip 4 which bows outwardly when a socket contact is inserted. A projecting portion 5 (Fig. 3, not shown) on the strips 4 snaps into position behind part of the socket after the latter has been inserted, and an inwardlydirected flange 9 (Fig. 3, not shown) provided at the mouth of the housing, prevents forward movement of the socket. A set of any required number of housings may be obtained by cutting through the integral rib 2 and web 2a at the appropriate points. With the junction web 2a as shown the rib 2 may be bent as shown so as to bring the opposite ends of the housings 1 closer together to accommodate contact pins which are positioned closer together. Alternatively the rib 2 may be bent to form a circle from which the housings 1 extend radially.

Title: Improvements in or relating to carburetors
IPC: F02M7/00
Filed: 1940-02-01
Abstract: 542,761. Spray carburetters. BEARDSLEY, jun., G. E. Feb. 1, 1940, No. 2017. Convention date, Feb. 10, 1939. [Class 7 (iii)] To prevent overheating in high duty engines the fuel supply to the carburetter is increased to yield a richer air-fuel mixture only during the periods of high output. In the construction shown in Fig. 1, the normal fuel supply is fed to a nozzle 18 through a passage 26 and a calibrated orifice which opens directly into a float chamber 28. Additional fuel is supplied to the passage through an orifice controlled by a valve 40 which is actuated by a diaphragm 42 open on one side through a passage 50 to the pressure in the carburetter air inlet 12 and on the other side subject to the pressure at the throat of a venturi tube 14. The depression in the venturi tube is transmitted through a column of fuel which stands in a passage 48. In this construction an air passage may lead directly from the venturi throat to the top face of the diaphragm 42 and the fuel in the nozzle may be aerated by opening this passage 48 to the chamber 50a and providing a short conduit between the nozzle and the vertical link of the passage 46. In the construction shown in Fig. 2, fuel is delivered on the engine side of the throttle valve 23 through a nozzle 25. Fuel under pressure is delivered past a valve 33 to a chamber 37 having at 43 a calibrated orifice which discharges into a pipe line 45 leading to the nozzle 25. Additional fuel to the pipe line is controlled by a needle valve 47 carried by a diaphragm 49 which is open on one side through passages 69 and 21 to the carburetter inlet and on the lower side through a passage 61 (restricted at 63) and orifices 19 to the pressure at the throat of the venturi tube A communication between the passages 69 and 61 is controlled by a valve 73 connected to a barometric device 77. The spindle 35 of the fuel admission valve 33 carries diaphragms 41 and 51 and to a small extent the fuel pressures on the two sides of the diaphragm 41 determine the position of the valve. The valve however is mainly actuated by the diaphragm 51 which is subject to the differential pressure acting on the diaphragm of the valve 47. A pressure-equalizing passage 39a connects the chambers 39 and 39b. According to a modified construction of the arrangement shown in Fig. 2, the valve 47 is dispensed with and the additional supply of fuel is provided by an appropriate regulation of the supply valve 33 which is furnished with an actuating diaphragm in addition to those shown in Fig. 2. The additional diaphragm is actuated by the same differential as the diaphragm 51. Specification 523,895 is referred to.

Title: Blazed hologram fabrication
Inventor: SHERIDON N K
IPC: G03H1/18
Filed: 1971-01-18
Abstract: 1339991 Holography XEROX CORP 18 Jan 1971 [21 Jan 1970] 2262/71 Addition to 1231938 Heading G2J Blazed holograms are formed by exposing a photo-hardenable layer 32 having a randomly varying surface to an object modulated beam 22 directed at one face of the layer and a mutually coherent reference beam 26 directed at the other face of the layer to set up standing wave interference patterns. The developed hologram may be coated with a reflective metal e.g. aluminium. In reconstruction, a reconstructing beam of same coherence and wavelength as the reference beam may be made or a white light or multiwavelength beam may be used. The reconstructed image will be that only set up by the wavelength corresponding to the reference beam, other wavelengths will be diffused. To give multiple image the layer 32 may be sequentially exposed to light of different wavelengths, either through masks to avoid overlap or by using as a layer a material selectively hardenable by light of different wavelengths. The base 30 of the hologram is preferably a ground glass having one surface 34 randomly varying. This is coated with a photo-hardenable material 32. This may be a coating comprising a slurry of finely ground transparent material mixed with photo-resist. Alternatively a photo-hardenable layer may be coated on transparent substrate, the layer then being exposed to a highly diffuse beam of ultraviolet light. When developed the layer has a highly diffusing surface. During exposure the photo-hardenable layer 32 may be coated with a transparent layer 37 of same refractive index as layer 32. This extra coated may also be applied to the developed blazed hologram.
