Title: Improvements in electric current breaker
IPC: H01C7/02
Filed: 1925-06-10
Abstract: 259,272. Kapitza. P. June 10, 1925. Protective arrangements. - An electric protective device against overloads comprises a pellet 1 of lead or bismuth peroxide caked or encased by a body 7 of porcelain, marble, or lead oxide, and provided with metallic end-plates 3, 4 pressed tightly on to the pellet. These plates are included in series in the circuit to be protected, and under normal conditions the pellet offers little resistance to the flow of current, but upon an overload occurring the pellet is overheated and changes its chemical state so as to become a non-conductor, thereupon interrupting the circuit. Metallic powder may be embedded in the peroxide so as to decrease its resistance. The main pellet may be shunted by one or more smaller ones, each in series with a resistor, in the manner employed for ordinary fuses.

Abstract: 650,500. Artificial hands. STEEPER, Ltd., H., and PHILPOTT, W. J. June 4, 1948, No. 15124. [Class 81(ii)] In an artificial hand of the kind in which the digits are opened by a control and are closed automatically, there are provided two linkage systems operable by a single control member, one system opening and closing the digits and the other system being associated with locking means. As shown in Fig. 1 downward movement of cord 12 causes upward movement of pivot 28 which opens the fingers and thumb against force of spring 16. As shown in Fig. 3 downward movement of cord 12 also acts on a second lever system to move a locking member 17 downward and out of contact with a friction pad 18 fixed to the finger assembly: upon release of cord 12, the member 17 jams against pad 18 under the force of spring 16, thus preventing further opening of the fingers. Specification 650,502 is referred to.

Title: Improvements in the production of chromium-bearing alloys
IPC: C21C7/00
Filed: 1940-10-14
Abstract: 544,553. Alloys. UDY, M. J. Oct. 14, 1940, No. 15247. Convention date, Nov. 8, 1939. [Class 82 (i)] Iron alloys containing chromium are made by igniting in contact with a molten bath consisting mainly of iron an exothermic mixture comprising low-carbon, low-silicon, ferro-chrome-silicon, which preferably contains 4-16 per cent. of silicon and not more than 0.1 per cent. of carbon, and an oxidizing material which may consist of or contain one or more of the compounds sodium nitrate, sodium chlorate, sodium chromate, calcium chromate, calcium chromite, and manganese di-oxide. The particles of ferrochrome-silicon are bonded together by means of the oxidizing material and the mixture may be briquetted or agglomerated either by fusing and solidifying the oxidizing material or by moistening the mixture and heating it without fusion. If the ferro-chrome-silicon contains up to 20 per cent. of silicon, sodium nitrate may be provided for oxidizing part of the silicon and calcium chromate for oxidizing the remainder; if it contains over 20 per cent. of silicon, sodium nitrate, calcium chromate. and calcium chromite may be used ; and if it contains 30-40 per cent., calcium chromate and calcium chromite may be used. The low-silicon ferro-chrome-silicon may be obtained by oxidizing high-silicon ferrochrome-silicon. For example a mixture of ferro-chrome-silicon. chromite ore and sodium nitrate may be ignited and the higher grade ferro-chrome-silicon thus obtained may be smelted with chromite ore to effect further reduction of the silicon content. High-silicon ferro-chrome-silicon for use in the process may be made by smelting ore with carbon or with carbon and silica, for example as described in Specification 519,303. Specification 520,331 also is referred to.

Title: Improvements relating to time base circuits for cathode ray tubes
IPC: H03K4/10
Filed: 1946-05-21
Abstract: 612,244. Saw-tooth generating circuits. SCOLES, G. J., and METROPOLITANVICKERS ELECTRICAL CO., Ltd. May 21, 1946, No. 15370. [Class 40 (vi)] In a time-base circuit particularly for scanning a cathode-ray tube, in which a valve is rendered conducting by a trigger circuit, when the voltage developed across a resistor in the cathode circuit of the valve reaches a predetermined amplitude, a voltage is applied to the trigger circuit via a rectifier to render the valve non-conducting. The Figure shows a time base valve V3 and a trigger circuit comprising cathode-coupled flip-flop valves V1, V2, valves V1, V3 and V4 normally being non- conducting' and valve V2 conducting. When a negative pulse is applied at S, normal multivibrator action occurs, V2 being cut-off and V1 rendered conducting, thus initiating the timebase sweep by way of known circuits indicated at A. The current through resistor R4 increases until V4 conducts, the potential at P then increases and reduces the current through VI, thus causing the multivibrator circuit to return to its original state, cutting off the time-base valve V3.

Filed: 1949-06-13
Abstract: 683,204. Baling-presses. POWELL, W. N., POWELL, A. F., and ANDERTON, H. June 12, 1950 [June 13, 1949], No. 15667/49. Class 94(i) A baling-press comprises spools 23, 24 for feeding twine from both sides of the baling chamber and a pair of knotting devices 33, 34 which cooperate with a severing device 35 and a reciprocable member 28 formed with two pairs of twine guides carried by arms 30-32. The ends of the twine from the two spools are initially knotted together so as to form a length which extends across the baling chamber in the path of the incoming material and is extended into V-shape about a bale 20 as it formed by the ram 21. When the bale is completed, the member 28 is operated to carry a bend of the twine 25 across the baling chamber and then to engage the twine 26 so that both lengths of twine are positioned between the jaws of the knotting devices, the arms 30-32 straddling the knotting and severing devices as shown in Fig. 2. The jaws of the knotting devices are then operated to grip the twine, the severing device cuts the twine between the knotting devices and the latter are rotated in opposite directions to form the knots 36, 37, thus completing the loop around the bale 20 and forming a fresh length of twine extending across the baling chamber ready for the next bale to be formed. The knotting devices, which are of known construction, the severing device and the member 28 are operated by an auxiliary shaft, the drive to which is controlled by trip mechanism actuated by means, such as a star wheel, rotated by the bale as it is formed, so that the various devices are operated automatically as soon as the bale is completed. The completion of the knot-tying operation disconnects the auxiliary shaft and resets the trip mechanism. The knotting device 33 is resiliently mounted with respect to its driving mechanism so that it may rotate to the left to allow the knot 36 to be drawn off the jaws as the completed bale moves forward. The mechanism described is duplicated so that two loops are tied around each bale.
