Title: Electronic timer
IPC: H01H47/18
Filed: 1960-03-10
Abstract: 889,818. Transistor relay circuits. BENDIX CORPORATION. March 10, 1960 [March 13, 1959], No. 8530/60. Class 40(6). A timing circuit comprises a relay 19 which when actuated by the closure of onoff switch 13 completes a charging circuit for the capacitor 45 and causes increased conduction in the transistor 53 thus energizing relay 24 and causing relay contacts 23 to open to interrupt the energizing circuit of relay 19. Capacitor 45 then commences discharging through resistor 63 until the potential at the base of transistor 53 falls to such a low value that the current flowing through the transistor is insufficient to maintain relay 24 energized whereupon contacts 23 close, relay 19 is energized and the cycle of operations recommenced. Each actuation of relay 19 causes a stepping switch to be advanced one position. A thermistor 75 is connected to the base biasing circuit of transistor 53 thereby rendering the circuit substantially independent of temperature variations. A feedback resistor 65 between collector and base electrodes of the transistor stabilizes the cut-off point. Specification 636,113 is referred to.

IPC: B67B3/28
Filed: 1925-03-31
Abstract: 231,531. Boldt & Vogel. March 31, 1924, [Convention date]. Gearing for stopping and starting machinery.-In a machine for operating on bottles, and particularly for applying " crown corks " thereto, the bottle support comprises a part movable solely by the weight of the bottle to trip a latch holding under stress a spring, the unstressing of the spring permitting the main clutch to be engaged, whereupon, on completion of the operation, the spring is again stressed in the continued movement of the machine parts and automatically locked. The bottle rest 36, Fig. 1, provided with a depending rod 37, is movable vertically in a bottle support 41, and a member 35 pivoted at 38 to the rod 37 is maintained in the position shown by gravity and a stop 39 which abuts against the rod 37. The placing of a bottle on the rest 36 depresses the rest causing the member 35 to turn a bell-crank lever 32 which draws to one side a latch 25 connected thereto, this movement freeing a rocking lever 19 pivoted at 20 to the casing 5 of the machine. The rocking lever 19 is formed with a slot 21, concentric with the pivot 20, in which moves the pivot of a follower or roller 22 connected by a spring 24 to the bottom of the lever 19. A cam track 23 on the loose member 9, Fig. 2, of a clutch on a main driving shaft 1 maintains the roller 22 normally in the position shown in Fig. 1, the spring 24 being extended. The movement of the latch 25 allows the spring 24 to raise the lever 19 and draw an inclined surface 18 thereon out of contact with a shoulder 17 on a spring-pressed pin 8 mounted in the clutch member 9. The pin engages a clutch member 6 fixed on the shaft 1 causing a cam 10 on the loose clutch member 9 to reciprocate the shaft 13 of the crowning head. As the movement progresses, a flat portion of the cam 23 engages the roller 22 allowing the lever 19 to drop and the roller to pass down the slot 21, whereupon the latch 25 swings back to the locking position, the curved portion of the cam 23 raises the roller 22 and, the lever 19 being locked, the spring 24 is extended. As the clutch member 9 completes one revolution, the surface 18 withdraws the pin 8 from the clutch member 6. The bottle is removed from the rest 36 which rises under the influence of a spring 45, the member 35 slipping past the lever 32 and falling into place by gravity. During the capping operation, the rest 36 seats on the bottle support 41 which can yield against the action of a stiff spring 42 and spring-pressed fingers 47.

The parent Specification describes apparatus for the reception of code signals which comprises an electron valve for each code combination to be received, only the valve which corresponds to the particular combination just received being brought to its conductive state. The present invention is a modification of one embodiment of such an apparatus, and provides a visible record of the received data. Each electron valve in this embodiment has thirty-five anodes, each connected to an element of a 7 Î 5 mosaic. The mosaic elements are wires 50 mounted to form a recording head, and the head is movable relative to an electro-sensitive record sheet 51. Certain of the anodes of each valve are isolated so that, when a valve is conducting, only certain of the mosaic elements are energized, thereby to reproduce the corresponding symbol on the record sheet. The use of two record heads is mentioned, one moving across the sheet and printing while the other is returned to the beginning of the next line prior to printing.

Title: Rectifier connection
IPC: H02M7/06
Filed: 1942-06-25
Abstract: 558,269. Converters. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. June 25, 1942, No. 8718. Convention date, July 11, 1941. [Class 38 (ii)] [Also in Groups XXXVI and XXXIX] A substantially uniform D.C. suitable for a measuring instrument and forming a true image of another direct current is obtained by rectification from an A.C. source by connecting in series on the D.C. side two or more rectifiers 4 which are subjected to A.C. voltages relatively displaced in phase. In the form shown current transformers 3 in two phases of an A.C. supply leading to a rectifier 1 produce the displaced A.C. voltages. The D.C. current from the main rectifier 1 is smoothed so that the wave form of the currents through the primaries 3 will be rectangular and the rectified currents that each secondary 3 tends to produce will also be rectangular with zero points out of phase so that when combined in series a uniform current results. In a modification, Figs. 3, 4 (not shown) a three-phase A.C. is fed to three transductors whose D.C. windings are connected in series and traversed by a current to be amplified. The A.C. windings of the three transductors are connected across three rectifiers which are connected in series on the D.C. side.

Title: Improvements in or relating to float controlled valves for cisterns
IPC: E03D1/32
Filed: 1953-03-30
Abstract: 766,538. Float-actuated valves. CLAYTON, N. A. March 30, 1954 [March 30, 1953], No. 8758/53. Class 135. In order that a float-operated cistern supply valve may open and close more quickly, a biasing chamber 8, open at its top and formed integral with a cylindrical float 4, is connected by a flexible hose 21 to the outlet 22 of the supply valve 14 and provided at its bottom with an adjustable outlet 9. The usual ball float is removed by shortening its float arm 17 which engages a stirrup 18 formed on an arm 1 carrying at one end the float 4 and the biasing chamber 8 and pivoted at its other end on a pivot pin 15 on which the arm 17 is pivoted. An adjustable screw 19 determines the water level which is to be maintained in the cistern. When the level of water in the cistern commences to fall and the valve begins to open, water flows into the chamber 8 to load the float and accelerate the opening of the valve. On the valve approaching its fully closed position when the cistern is being refilled, water leaves the chamber 8 at a faster rate than it enters it to effect a more rapid closure of the valve. In a modification, the float and chamber are made somewhat longer and the outlet 9 is replaced by a series of holes gradually increasing in size from the bottom of the chamber to the top.

Alternatively, it may have a concavity so as to produce a completely spherical combustion chamber. The sparking plug is located near the top of the chamber. The stroke is preferably less than the cylinder bore. The valves are held closed by torsion rods 11 which act partly by torsion and partly by flexion.
Patent GB-231889-A (GB)
IPC: C09B9/00
Filed: 1925-04-03
Abstract: Esters of leuco compounds of vat dyes are produced by treating the leuco-vat-dyes with chlorsulphonic alkyl esters in the presence of a tertiary base; the reaction will take place even in presence of some water.  They may be employed for dyeing either directly, or, if little soluble, after saponification to the alkali salt of the acid ester.  According to examples leuco thioindigo red is treated with chlorsulphonic ethyl- or methyl-ester in presence of pyridine, diluted with a little water and filtered; by further dilution and acidifying with hydrochloric acid the neutral esters are precipitated and can be recrystallized from hot water; they are easily saponified by dilute caustic soda to the sodium salts of the acid esters: neutral sulphuric esters are simlarly obtained from leuco-6-ethoxythioindigo and chlorsulphonic acid methyl ester, and from leucothioindigo and chlorsulphonic acid isopropyl or n-butyl ester.  The process is applicable to other indigo dyestuffs. Chlorsulphonic acid isopropyl and n-butyl esters are obtained by interaction of equimolecular proportions of the respective alcohols and sulphuryl chloride below 10 DEG  C.; the product is shaken with ice-water and dried and may be then used directly.

During start up and shut down of a once through boiler, natural circulation through the tube walls 8 occurs to prevent overheating. Feedwater from line 1, after passing through economizer 4, passes through injector 6, thereby entraining recirculating water that has already passed through tubes 8, the water then being fed through downcomer 7 and lower headers 8a to the tube walls 8. The steam/water mixture produced therein, passes through upper headers 8b and line 9 to header 10, wherein trough-like deflectors 10a cause separation of the water from the steam, the former passing through line 11 back to the injector 6, and the latter passing onwards through line 13 to cooler 14 which also functions as a steam/water separator. Water from outlet head 15 of cooler 14 passes back down line 22 to be reintroduced into the downcomer 7 at point 24. The separated steam passes through line 16 to superheaters 17, 19 and steam pipe 20.
