Abstract: 828,533. Electric correspondence control. SUPERHEATER CO. Ltd., and RAINBIRD, N. C. Dec. 22, 1955 [April 30, 1954], No. 12577/54. Class 40 (1). Thermocouples are connected one at a time to a common recording apparatus via a single pair of compensating leads by a selector close to the thermocouples controlled from a point in the neighbourhood of the recorder. In one arrangement the thermocouples are selected individually. In another the thermocouples in a selected group are connected to the recorder in succession automatically. As shown, Fig. 1, a plurality of thermocouples at Location B are connected individually to a multi-point potentiometric recorder (not shown) at Location A by a single pair of compensating leads (not shown), selection being effected by a multi-bank uniselector switch at Location B, one section of which comprises resistors R of equal value between its contacts and is connected in shunt with a similar uniselector switch which is manually operated at Location A. The two uni-  selector switches are supplied with rectified A.C. to form a balanced potentiometer network, any error signal in lines W, Z, which are connected between the wipers of the switches, being applied to the grid of an A.C. supplied thyratron E to operate a selector impulse motor which steps on the switch at Location B until it is in positional correspondence with the switch at Location A. Fig. 2 (not shown) shows a cylically operated switch at Location A capable of selecting a number of different sequences of three thermocouples from an installed number of five. If power at the same voltage is available at both locations, lines X and Y may be dispensed with. A high-speed relay may replace the thyratron to control the selector impulse motor. A relay may be provided which in the event of circuit or supply failures, becomes de-energized and short-circuits the thermocouple circuit, the arrangement being such that this causes the recorder to record the ambient air temperature.

Patent GB-179552-A (GB)
IPC: F16F7/12
Filed: 1922-05-05
Abstract: 179,552. Junkers, H. May 6, 1921, [Convention date]. Machinery frames.- In means for preventing shocks in aircraft, vehicles, and machinery generally, a deformable member, preferably of copper, is arranged to be stressed beyond its elastic limit by exceptional shocks, so as to absorb energy, but not to be broken, and is preferably combined with spring means. The part 4 to which the force is applied may be connected to the relatively stationary member 10, Fig. 3, by a tension spring 1 in series with a deformable rod 2, the spring and rod being connected by a bar 8 adapted to be engaged by stops 7 moving with the part 4, so that first the spring 1 is stressed,. then the stops 7, 8 engage to limit spring strain, and then the bar 2 is stretched, stretching being limited by stops 9 moving with the part 4 and engaging the fixed member 10. The stops 9 may be carried on an extension of the bar 8, in which modification the spring will still function even if the rod 2 breaks prematurely. The stops 7, 9 may be omitted. Fig. 2 shows a form in which deformable rods 2', 2" act in parallel with the spring 1, stretching being limited by stops 6. In this form, the spring 1 acts first independently of and then together with the rods 2<1>, 2<11>. In a practical form of this device for use with aeroplane landing carriages, the usual spring loops of india-rubber or spiral wire are surrounded loosely by loops of copper wire and by larger loops of unyielding material such as steel wire to act as stops. The steel loops may be omitted. Fig. 6 shows an arrangement in which the spring 1 is arranged in series with a strong deformable member 2 and in parallel with weaker deformable members 2', 2", which are stretched to the predetermined limit before the member 2 begins to stretch. Limiting stops 7, 9 may be used in this construction. In a further modification, the rods 2', 2" pass through and their upper heads 3 engage the fixed part 10 only when the spring has been fully extended and the rod 2 has been partly stretched. A practical embodiment of the form shown in Fig. 3 as applied to aeroplane landing carriages is shown and described, the spring 1 taking the form of rubber bands and rubber blocks being carried by the part 4 to strike the underside of the bar 8 and prevent shock when the strain is suddenly removed. In the modified construction shown in Fig. 7, a cross piece 8' is connected to one member 12 by deformable rings 2 and to the other member 13 by rubber bands 1 and by loose stop rings 7, stop lugs 9<1> being provided on the member 12. The stop rings 7 may be replaced by deformable rings. Rubber buffers 16 prevent shock when the strain is suddenly released. In aircraft, a stream-line casing may surround the parts.

Title: Hardness measuring apparatus
IPC: G01N3/44
Filed: 1966-03-23
Abstract: 1,079,305. Testing hardness of materials. A. ERNST. March 23, 1966 [April 15, 1965], No.12812/66. Heading G1S. In an apparatus for measuring the hardness of a material, the measuring instrument comprises a penetrating means 1, means for applying a preload and then a further load, both means being actuated by a common member 85 Fig. 1 (not shown). The pre-load is applied by means of spring 107 acting on the penetrating tip holder 2. The instrument includes a membrane 6 defining a chamber which is connected to a capillary tube 8 containing a coloured liquid. The membrane is moved by a sphere 4 which is raised by a rod 62 connected to a cross-member 91. Inside the casing 30 is a sleeve 33 resting on spring 34, sleeve 33 supporting inner casing 37 by screws 36, a load spring 38 acting against said inner casing. The upper end of load spring 38 acts on a threaded locking nut 100 which regulates the load. A return spring 31 rests between fixed cylinder 65 and sleeve 33 and outer casing 30. As lever 85 Fig. 1 (not shown) is lowered the casing 30 is first lowered compressing spring 34 until the tip 1 comes in contact with the surface under test the tip holder 2 sliding on slider 3 until the guard 44 contacts the test surface. At this point the only load on the penetrating means is the spring 107. As the sleeve 33 is lowered further, the inner casing 37 comes under the action of load spring 38 till cross-member 91 contacts rod 41 whereupon the load is applied to the penetrating means. When the meniscus in the capillary tube 8 comes to a stop the load is released. The difference in the reading of the meniscus in load and pre-load positions is a measure of the hardness. The signalling device comprises a lamp 120 Fig. 1 (not shown) which is actuated when the pre-load and load is applied.

Filed: 1947-05-13
Abstract: 623,689. Control of motors. WHEELER, H. D., MOSSAY, P. A. H., and DEAN, J. May 13, 1947, No. 12925. [Class 38(iii)] An electric motor control system comprises a differentially wound exciter E1 connected to the motor M to be controlled so that alteration of the balance of currents in the exciter field windings by any variation of the motor current causes the exciter armature to buck or boost the current in the motor series winding s. A field F1 of the exciter carries the armature current of the motor M and another field F2 is separately and variably excited so that with normal motor current the exciter balances the normal volt drop in the series field. The torque of the motor is thereby maintained inversely proportional to its speed. One application of the invention is to machines wherein material is wound on a reel with a constant tension in the material as the diameter of the reel increases. The motors MS may be those driving other sections of such a machine at pre-set constant speed or speeds.

Title: Improvements relating to the manufacture of viscose
IPC: C14C3/24
Filed: 1922-05-08
Abstract: Wood and like lignified materials are resolved by treatment at 100-110 DEG C with a strong aqueous solution of sulphurous acid which is originally substantially free from sulphuric acid.  Preferably the process is carried out in a digester lined with acid-resisting cement, and the materials under treatment are rapidly agitated. In an example, wood prepared as for the bisulphite process is treated with six times its weight of a seven per cent solution of sulphurous acid purified from sulphuric acid.  The mass is heated with open steam for six hours; then steam at a temperature of 105 DEG -110 DEG C is employed for a further ten hours to complete the resolution.  The liquor containing the lignone derivatives may be evaporated to dryness, preferably under reduced pressure, or prepared in concentrated form for transport.  These derivatives are stated to be different from those contained in sulphite-cellulose liquor.ALSO:Sulphurous acid is rendered free from sulphuric acid by treatment with barium sulphite, or, according to one Provisional Specification, with barium acetate or bisulphite.  Specifications 2924/66, 385/67, 9509/84, [all in Class 96, Paper &c.], and 5269/87 are referred to.
