Title: Improvements in or relating to readily-portable weighing scales
IPC: G01G19/02
Filed: 1948-09-08
Abstract: 698,793. Electric indicating systems. GWATKIN, J. S. (Black & Decker Manufacturing Co.). Sept. 8, 1948, No. 23648/48. Class 40 (i). A portable scale for weighing heavy loads comprises a hollow container having a rigid base inflexible in all directions and a rigid vertical peripheral wall including an upwardly directed peripheral load sustaining portion, a flexible elastic load sustaining metal plate resting upon and flexing about the inner peripheral edge of the load sustaining wall portion, a strain gauge having electrical impedance elements incorporated therein associated with the underside of the plate and located between the plate and the base, a load centring means on the top of the plate located substantially centrally of the peripheral wall and positioned to receive the load to be weighed upon the plate, the central flexure of said plate downwardly under the centralized load varying an electric current that is passed through said electrical impedance elements, and means permanently connecting the plate and load centring means to the wall of the container without restraining the flexure of the load sustaining plate under load. The variable impedance device may be a carbon pile, a choke with a variable air-gap, or resistant strain gauges. As shown in Fig. 1 the device comprises a cup member 116, which may be attached to the lifting head 117 of a screw jack, and a flexible circular plate 113 supporting the load through a central boss 120 and having arms 111, 112 which bear on each end of carbon pile 110. In a modification, Fig. 4, a flexible plate 113 has one depending arm 130 which supports the choke coil 131, the arrangement being such that flexing of plate 113 varies the air-gap 135 and thus the inductance of the coil. The modified arrangement shown in Fig. 6 has a load supporting flexible plate 137 which varies the air-gaps 147, 148 between poles 142, 142' of choke coil 145. A somewhat similar arrangement is illustrated in Fig. 10 (not shown). In the Fig. 14 the load plate 161 bears through a stem 178 on a flexible tongue 171 which is anchored to the cup 160 at its end 171' is urged by spring 173 into engagement with the stem 178 and forms an armature which, according to the load, varies the air-gaps 187, 188 and thus the inductance of choke coils 185. The modification shown in Fig. 20 has resistance strain gauges 205 secured radially beneath the load plate 201, and in Fig. 21 similar gauges 220 are arranged radially on each side of a flexible plate 218 which is engaged by stem 219 secured to the load plate 211. A similar arrangement is also illustrated in Fig. 25 (not shown). When any of the above described scales are used to weigh a vehicle, they may be placed one under each wheel and have change over switches connecting them with a power supply and ammeter, either all in series, or individually, so that the total load and the load on each wheel can be measured separately.

Title: Improvements in or relating to photosensitive electrodes
IPC: H01J40/06
Filed: 1938-08-11
Abstract: 500,531. Photo - electric cells. ELECTRICAL RESEARCH PRODUCTS, Inc. Aug. 11, 1938, No. 23709. Convention date, Aug. 26, 1937. [Class 39 (i)] A photosensitive electrode, particularly a cathode for a photo-electric cell is formed by applying to a conducting support a layer of an easily reducible metallic compound such as silver oxide, tin oxide or copper oxide mixed with a stable refractory compound, such as zirconium oxide, aluminium oxide or aluminium silicate, reducing the metallic compound so as to leave metallic particles intimately mixed with the refractory compound, and applying an alkali metal to the layer in the presence of heat so as to cause the alkali metal to penetrate into the surface of the layer. The cell comprises a cathode 12 in the form of a semi-cylindrical plate mounted on the stem 6 by support wires 8, 8a, 8b, and a nickel wire anode 9. A heavy copper wire 13 partially encircling the stem carries between its ends a metallic capsule 14 enclosing a mixture which produces caesium vapour when heated, and a nickel shield 15 is supported between the capsule and the cathode. Current is induced in the wire 13 by an external coil 17 for heating the capsule. An apparatus for treating four cells simultaneously is described and comprises an electric heater, a liquid air trap, two McLeod gauges, a mercury vapour pump, a mercury cut-off, a vacuum pump, an ionization micrometer, and two gas supply units, one. containing hydrogen for use in the reduction of tin and copper oxides, and the other argon for introduction into the finished cell. In one method, the concave surface of the nickel cathode is roughened and coated with a suspension of silver and zirconium oxides in water to which a small amount of zirconium nitrate has been added. The cell is then sealed in the heater, evacuated and heated to raise the cathode temperature to 300-400‹ C. so that the silver oxide is reduced. The coil 17 is connected to a source of high frequency current to " flash " the capsule 14 whereby caesium vapour is deposited on the glass walls of the cell. The cell is subsequently heated by air currents to transfer the caesium to the cathode. An electric circuit is described whereby the sensitivity of the cells can be indicated by an ammeter. When the required sensitivity is reached, the cells are allowed to cool and argon is admitted. Methods are described of producing a cathode with a matrix of caesium, tin and aluminium oxide and a cathode with a matrix of caesium, copper and aluminium silicate. Potassium, sodium, rubidium or lithium may be used in place of caesium.

Title: Arc welding apparatus with coated electrodes
IPC: B23K9/12
Filed: 1937-09-03
Abstract: 501,757. Uniting by fusion. KJELLBERG ELEKTRODEN & MASCHINEN GES. sept. 3, 1937, No. 24159. Convention date, Sept. 3, 1936. [Class 83 (iv)] In an automatic arc welding apparatus having a pair of coated electrodes alternately advanced to and withdrawn from the work, the advance movement is effected by a single electric motor connected to the electrode holders alternately through separate electromagnetic couplings. Withdrawal of consumed electrodes is automatically effected by springs or counterweights or by the motor through reversible electromagnet couplings. Th( electrodes 1, 2 are fixed in holders 5, 8 reciprocated by racks 6, 9 and pinions 7, 10 through alternately connected electromagnetic couplings 12 13 from an electric motor 11 continuously rotated in one direction. When the coupling 12 is in circuit the electrode 1 is advanced as it burns away. When it is nearly consumed the coupling 13 is connected and when the ends of the two electrodes are the same distance from the work so that the arc is taken over by the electrode 2 the coupling 12 is disconnected and the electrode 1 withdraws. The consumed end is then replaced by a now electrode. The switching in and out of the couplings may be effected by contacts operated by the holders or by a control drum or disc, preferably given one rotation during the consumption of two electrodes. When withdrawal is effected by the motor the electromagnetic couplings are reversible, being operated by the excitation of a second coil formed so as to cause the pinions to rotate in the reverse direction at a higher speed than in the forward direction. The electrodes may be cooled by air or the like. Specification 447,637 is referred to.

Title: Improvements in apparatus for handling granular or lumpy material
IPC: B65G67/00
Filed: 1934-08-24
Abstract: 443,292. Shoots ; spreading material; laying cables on drums during winding. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and MARSHALL, C. H., Fraser & Chalmers Engineering Works, Erith, Kent. Aug. 24, 1934, No. 24469. [Classes 78 (i), 78 (iv), and 78 (v)] The apparatus for delivering lumpy material such as coal, described in Specification 429,598, is modified by the omission of the final outwardly-directed shoots. The present apparatus comprises a rotary shoot which delivers for a short initial period through the open bottom until the latter is blocked by the accumulation of heaped material, after which delivery takes place laterally through a side opening in the wall above the level of the bottom. Fig. 1 shows a telescopic shoot having a bottom section adapted to be rotated by worm gearing driven by a motor 8. When delivery is being effected through the side opening, the material received from the inclined shoot 5 rolls gently over the surface of the heap as the shoot rotates. During this period the part of the shoot below the side opening is embedded in the heap of material sufficiently to take up the lateral thrust reaction on the shoot caused by the lateral delivery. An involute wing member 7 may be fitted at one side of the exit opening so that its vertical wall is inclined downwardly at the angle of repose of the material. The impact of the issuing material on this wing member may produce the rotation of the shoot. As the heap grows higher, the shoot is telescoped or raised as a whole by the crane 2. The shoot is supported for tolescoping by three ropes 9 which pass over pulleys 10 arranged at different heights to a common winding barrel 11. The latter is feathered on a driving shaft 12 driven by worm gear from a motor 15 and also has a screw-and-nut connection with the upper bearing of the driving shaft, so that rotation of the latter causes the drum to move axially, proportionately to the raising or lowering of the shoot, so that each cable is laid evenly on its own portion of the drum. The two motors 8, 15 may be operated through flexible leads from controls on the deck of the ship being loaded.
