Title: Improvements in or relating to flying-time and like indicators
IPC: G04B5/00
Filed: 1933-08-22
Abstract: 421,207. Clocks; indicating -apparatus; counting-apparatus. AIR LOG CO., LTD., and MAYERS, H. C., 193, Elgin Terrace, Maida Vale, London. Aug. 22, 1933, No. 23371. [Class 139] [See also Group XIX] In a device of the kind described in Specification 361,663, [Group XIX], for integrating intermittent time intervals, particularly for use on aircraft to indicate actual flying time, and in which the trip-time indicating means is reset to zero by a member which simultaneously winds the clockwork mechanism, one revolution of the winding member corresponds to a plurality of revolutions of the trip-time minute hand. The mainspring 24 is secured at its inner end to the winding spindle 25, and drives through a ratchet 27, and pawl 28, a shaft 31 controlled by an escapement 36, 37, 38, 39. The shaft 31 is frictionally driven and carries gear wheels 53, 54, meshing with gear wheels 52, 55, respectively. The wheel 52 is carried by a sleeve 51 through which the trip-time minute hand 50 is driven at the same speed as shaft 31. The trip-time hours are indicated on a disc 58 visible through an aperture in the dial 18, Fig. 4, and advanced at each hour by a projection 57, Fig. 7, engaging a star wheel 59 rigid with the disc. Normally, the clock is locked by a wire 40, Fig. 1, engaging between teeth of the escape wheel 36, the wire being withdrawn through a linkage 41 when the air pressure in a capsule 12 is increased, for example, when the aeroplane is in flight, so that only flying time is indicated. At the end of each flight the shaft 25 is rotated by a knob 26 to wind the mainspring 24, and through the gearing 55, 54, 53, 52 zeroises the trip-time indicating members 50, 58, the ratio of the wheels 55, 54, causing one revolution of the shaft 25 to result in a plurality of revolutions of the hand 50. A projection 61 on the star wheel 59, Fig. 7, engages a stop 62 at the zero position, and to prevent the slight return or backlash movement of the ratchet mechanism 27, 28 being transmitted to the hand 50, the gear 55 is connected to shaft 25 through a lost motion device shown in Fig. 5. The total flying time is indicated on discs 63 (tenths), 64 (units), 65 (tens), 66 (hundreds), Figs. 2, 4, driven by star wheels in known manner, the disc 63 being driven directly from the wheel 29. In a modification, the hand 50 is secured directly to the shaft 31. The calibration of the dial and the indicating means may be varied. The capsule 12 may be actuated by water, oil or other liquid, and may be replaced by other controlling means. According to the Provisional Specification, the feature of arranging the resetting means so as to be unaffected by the backlash of the ratchet mechanism, may be applied to other time integrating devices.

Title: Improvements in or relating to compression testing apparatus
IPC: G01N3/08
Filed: 1936-08-28
Abstract: 482,373. Testing physical qualities of materials. DUNLOP RUBBER CO., Ltd., SIMPSON, E., STUBBS, A. J., and NORCROSS, T. Aug. 28, 1936, No. 23600. [Class 106 (ii)] Apparatus for testing more especially cushions and cushioning materials such as sponge rubber under compression comprises means for submitting a test piece to a predetermined load, means for further compressing the test piece a predetermined proportion of its thickness under that load, and means for measuring the load at that degree of compression which is effected automatically irrespective of the different thickness or compressibility of different test pieces. The testing unit is carried by a sprocket chain 5 operated from a motor 7 and comprises a universally-mounted platen 9 above which is a weight 11. A dynamometer 12 from which the unit hangs is so calibrated that it reads zero when the whole weight of the unit is hanging freely from the chain 5. A test cushion 8 is placed on the platform 1 and the switch 3 moved down. This starts the motor and the unit is lowered the platen 9 engaging and compressing the cushion 8. When the dynamometer registers the initial load, two kilograms, a mercury contact is tilted by a cam on the spindle of the dynamometer. This contact controls a differential 13 comprising two pulleys 17, 18 the diameters of which are in the proportion of 4 to 6 both of which are carried by a spindle 19 mounted on a carriage 20 which rises and falls with the unit. The driver pulley 17 is encircled by a tape 21 one end of which is attached to the fixed framework and the other to the periphery of the pulley. As the unit moves up and down the driver 17 is caused to rotate. Encircling the selector pulley 18 is a tape 23 one end of which is fixed to the periphery of the selector and the other to a weight 24. When the switch actuated by the cam on the dynamometer spindle is tilted, an electromagnet within the differential is energized to clutch the selector 18 to driver 17. Thus as the unit lowers, the pulley 18 is rotated by the pulley 17 and pays out the tape 23 until the weight 24 carried by the latter engages a contact switch 25. This causes the displacement of a switch panel carrying a pair of mercury switches one of which makes a circuit of an electromagnet to stop the dynamometer pointer and hold the reading and also causes declutching of the pulleys. The other switch stops the motor. The switch handle 3 is then lifted to reverse the motor 7 and raise the unit for a fresh test. The spacing is effected by the contact weight always starting its independent or proportionally different movement from a position spaced away from the contact a distance equal to the thickness of the cushion under its initial compression.

Abstract: 226,763. W³nsch, G., and Askania- Werke Akt.-Ges. vorm. Central Werkstatt-Dessau und C. Bamberg- Friedenau. Sept. 20, 1923. Mariners' compasses.-For indicating deviations from a set course, the compass bowl 55 carries a small needle 58 of magnetic material, mounted in a bracket 57, and having so small a magnetic moment that it is influenced only by the compass magnet. The needle 58 carries a pipe 59 into which a pressure fluid is delivered by a pipe 60 The pipe 59 terminates adjacent the end of a pipe 63 connected to a pressure gauge 64. Relative movements of the pipes 59, 63 thus cause variations in the reading of the gauge. For causing the device to operate a servo-motor controlling the steering gear, the pipe 59 is caused to deliver the pressure fluid into a tube having two branches f<1>, g<1> leading to the opposite sides of a piston i. The movements of the piston control the steering gear.

Abstract: 842,005. Magnetic compositions. PHILIPS ELECTRICAL INDUSTRIES Ltd. Aug. 7, 1956 [Aug. 10, 1955], No. 24173/56. Drawings to Specification. Class 38 (2). Ferromagnetic material suitable for use at frequencies of at least 50 Mc/sec. consists of simple and/or mixed crystals having a formula represented by Ba M<SP>II</SP> Fe 6 <SP>III</SP> On wherein up to half the Ba may be replaced by Sr, or up to a quarter by Ca or Pb, or part by two or more of these elements, wherein not more than onetenth of the Fe<SP>III</SP> may be replaced by A1 and/or Cr and wherein M<SP>II</SP> designates one or more of the bivalent metals Mn, Fe, Co, Ni, Cu, Zn and Mg. The crystals are rhombohedric having a C-axis of about 43.5Š and an A-axis of about 5.9Š. The material may be made by sintering at more than 1000‹ C., preferably between 1150‹ and 1300‹ C. a mixture of oxides or compounds such as carbonates, oxalates and acetates which convert to oxides on heating. The mixture is first ground in a ball mill with ethyl alcohol. The starting material may be presintered at 900-1200‹ C., reground and if desired, resintered several times. The starting material may include preformed reaction products of two or metal oxides, e.g. Ba Fe 12  O 19  having the structure of magneto-plumbite. The sintering processes are carried out in air or oxygen. Compounds containing Fe<SP>II</SP> are sintered at above 1200‹ C. in an atmosphere poor in oxygen. To facilitate sintering, silicates or fluorides may be added, and water or an organic binder may be used when the material is pressed to its final shape. Examples are described, specifying appropriate amounts of starting material and the manufacturing steps. A table giving composition, and specifying properties including values of real permeability Á<SP>1</SP> is given. For some compositions curves are given showing variation of Á<SP>1</SP> and with frequency (Figs. 1-5, not shown). Small quantities of impurities, such as ferrites may be found in the materials. By bringing the material to the state of magnetic remanence before use, the losses may be reduced.

Title: Timing switches and mechanism
IPC: G04F3/06
Filed: 1937-09-04
Abstract: 501,665. Actuation of switches. EAGLE SIGNAL CORPORATION. Sept. 4, 1937, No. 24242. Convention date, Sept. 14, 1936. [Class 38 (v)] A switch for accurately timing the closure of a circuit comprises a synchronous motor 115, Fig. 9, which drives a spindle 125 on which is fixed a clutch member 119. Loosely mounted on spindle 125 is a pinion 117 rigid with a clutch member 121 which is pressed into engagement with clutch member 119 by a spring 131 acting through a loose sleeve 129. Pinion 117 drives a gear 137 which drives a pinion 143 having a threaded bore which engages a threaded portion of a fixed axle 145 so that it travels axially downwards on rotation by the motor. The upward limit of movement of pinion 143 is determined by the engagement of a face 161 of the pinion with a face 159 of an adjustable pinion 157. From this rest position the pinion 143 travels downwards due to the motor drive until a face 155 of the pinion engages a face 153 on an arm 147 to terminate actuation of the switch. If now a fork 133 rotates to disengage the clutch 119, 121, a spring 139 causes the pinion 143 together with gear 137 and pinion 117 to rotate back to the rest postion. The time during which the controlled circuit is made is the time taken for the pinion 143 to move under motor drive from the rest position to the position in which it engages and rotates the arm 147. This is determined by adjusting the pinion 157 by means of a pinion 163 driven by a knob 113 which carries graduations which co-operate with graduations on a second geared dial 249 to indicate closely the amount the knob 113 has been turned, in which position it is then clamped by a nut 167. The clutch actuating fork 133 is operated by an electromagnet 171, Fig. 13, acting through links 173, 175 rock-shaft 177, and links 179, 183 and 187. Link 187 also carries a rod 239 which engages a cradle (not shown) on which the contact arms 215, Fig. 20, are carried. When the cradle is lowered, insulating blocks 205, 207, 209, 211 and 213 fixed to the contact arms, rest on projections on a pivoted latch plate 195. In this position, the controlled circuit is closed as also are hold on circuits for the motor 115 and electromagnet 171. At the end of the timed period the pinion 143 rotates arm 147 to move link 193, Fig. 20, to turn latch plate 195 in clockwise direction from underneath the insulating blocks. This breaks the circuits, causing the clutch to be disengaged and the contactcarrying cradle to be raised. The pinion 143 is then reset by spring 139 and the apparatus is ready for a further operation. Several modifications of the cycle of operations are described.
