Title: Ultrasonic delay line
IPC: H03H9/36
Filed: 1961-04-18
Abstract: 982,176. Electromechanical delay lines. CORNING GLASS WORKS. April 18, 1961 [April 18, 1960], No. 14037/61. Heading H3U. In order to avoid spurious " third-time signals," an ultrasonic delay line makes use of an input or output transducer having a radiation pattern which includes a major lobe lying at an angle to the normal of the radiating face. If two sources 12, 14, Fig. 1, are excited in phase opposition, the radiation pattern consists of two major lobes 40, 42 directed at an angle #to the normal 43. The input facet 11 of transmission body 10 is so orientated that one of the lobes is directed towards an output transducer 34 and the other towards a dissipative load 48. In a conventional delay line, reflection of energy, first at the output transducer then at the input transducer, gives rise to an unwanted third-time signal. In the arrangement shown, the spurious signal is reflected by the input facet 11 towards the load 48. In the delay line of Fig. 8, the transmission body 10 is of the polyhedral type making use of multiple reflection. The input facet 11 lies at an angle #to the facet (broken line) which would be used for a conventional transducer. Output transducer 34 receives the energy in lobe 40 after multiple reflection, and load 48 dissipates the energy in lobe 42 and that of spurious signals. The lobes 40, 42 may be made unequal in size by using a pair of sources having unequal outputs. This, however, results in a decrease in the angle 0. The magnitude of this angle is best determined by photographing the stress pattern in the body 10, using polarized light. The two sources may comprise two separate transducers or two halves 12a, 14a, Fig. 6, of the same transducer. Arrows 22, 24 indicate that the two halves are polarized in the same direction. Connections to electrodes 16, 18, 20 are such that the two halves are connected in series and have oppositely directed signal fields. If four electrodes 16a, 16b, 18, 20, Fig. 7, are used, the transducer sections may be connected in parallel. The vibrating element may be sawn in half to produce two separate transducers. These may be oppositely poled and connected, in series or in parallel, in such a manner that the signal fields are similarly directed. The transducers shown make use of the compressional mode. Other modes, e.g. the thickness-shear mode, may also be used. U.S.A. Specification 2,418,964 is referred to.
Patent GB-311279-A (GB)
IPC: C10J3/24
Filed: 1929-05-06
Abstract: 311,279. Humphreys &, Glasgow, Ltd., (Assignees of Parsons, M.). May 8, 1928, [Convention date]. Producers.-Two or more carburetted water gas sets each having an electric motor - driven automatic control machine for operating the cycle of air blasting and gas making are provided with an electric motor-driven master machine for starting the control machines in predetermined sequence and putting out of service any machine which gets out of step with the others, The 'motor of each control machine drives a shaft 101 which rocks a crank 102 about 20‹ and is geared with shafts 103, 104 carrying a number of cams 105, 106 corresponding, to the number of valves 6 to be operated. Movement of bell cranks 107, 108 which ride on the cams effects the insertion of pawls 111 or 112 in the path of the crank 102 and so causes a sliding bar 119 to move to left or right. An operating lever 114 is thus caused to move a piston 121 which puts a pipe 122 or 123 leading to a hydraulic cylinder 124 into communication with the pressure port 126 of the valve housing 13 and so operates a valve 6 of the water gas set. The master machine for controlling e.g. three sets includes three sets of cams 73, 74 and switches 75. 76 on shafts 71, 72. The cams are so shaped that switches 75 close before switches 76 open and remain closed until after switches 76 close. The motors driving the set machines and the master machine operate at the same speed. When a switch 75 is closed, a coil 317, Fig. 8, is energized to close contactors 310, 311 and 312, 313 and a circuit is established which starts, a control machine motor 50 and lights a pilot light 319. When the motor starts to rotate a switch 55 in each control machine is opened and the switch 75 also opens, but a holding circuit through switch 76 is maintained. If, however, a control machine does not synchronize with the master machine, switches 75, 55, 76 will not all be closed at the same time and both circuits will be open causing the motor 50 to stop. On the de-energization of a solenoid 320 its armature is caused to drop by means of a weight and to raise a pivoted lever to open the blade of a manual switch 350 which the operator must close after an accidental interruption. To do so while the lever is raised he must first move a pawl pivoted to it out of the path of the switch. A light 361 flashes each time the switch 75 is closed. In a modification switches 55, 76 are omitted, the operator manipulating switches 350 of the control machines in response to the lights 319, 361.

Abstract: 543,786. Agglutinated fibrous materials. SWEARS & WELLS, Ltd., and DRESSEL, K. Sept. 11, 1940, No. 14084. [Class 140] Leather-like material is made by impregnating fibrous material and a cotton wool with a binding agent and a dextrin, glue or gum, and then treating with a rubber dispersion by placing sheets of a material constrained between sheets of wire gauze or netting in a tank and rotating the tank about an axis parallel to and preferably spaced apart from the plane of the sheets. Bats of cotton wool are impregnated with the binding agent and pressed as described in Specification 543,779. The sheets are than clamped in batches between wire netting and impregnated with rubber latex as described in Specification 543,781. After squeezing and drying the sheets are treated in a fixing bath containing acetic acid, to which borax and/or tartaric acid may be added, squeezed, stretched and dried.

Title: Improvements in or connected with gun fire spotting apparatus
IPC: F41G11/00
Filed: 1925-05-29
Abstract: 256,357. Barr & Stroud, Ltd., and French, J. W. May 29, 1925. Range-keepers; eyepieces.-Comprises improvements in observational instruments for gun fire spotting, which may be combined with transmitter and receiver mechanism and correction determining mechanism. In the field of view of a sighting device, e.g. a telescope, a series of position reference lines 2, readily distinguishable the one from the others, are situated. A target reference line 3, fixed in relation to the lines 2 and a movable index line 4, are also provided. The lines 2, 3 are mounted on a graticule A and the index line 4 on a movable graticule B actuated by the handle C, which is also connected to the commutator 5 of a transmitter D. The lines 2 differ in appearance, either by variation of thickness or by being composed of dots, dashes, or otherwise broken, or by being serrated, screw. or waved in form. The apparatus is arranged to show angular deflections and may transmit them to apparatus, Fig. 5, which introduces the range and gives a linear indication of the deflection. The motion of the handle C is communicated to the arm F after adjustment of the index line 4 on the splash, and the handle G is turned so that the scale on the drum F is brought to its fiducial position relatively to the pointer F<1>. The angular deflection is thus communicated to the nut 37 through the screw 36. The range is now set on the drum K, which causes the pinion 49 to be operated as described in Specification 189,870. [Class 92 (ii), Ordnance &c.] , which rotation will be a measure of the product of the angular deflection and the range, i.e. the linear deflection. To modify the apparatus for range spotting corrections the reference lines 2, 3 and the index line 4 are turned through a right-angle and the screws 43. 44 are made so that the pitch is proportional to the square of the range or the drum K is graduated proportionally to the square of the range. The lines 2, 3 may be illuminated obliquely from both sides or by transmission through the glass in its plane. If made of threads, the lines are maintained taut by fitting a spring at one or each end.
