Title: Improvements in or relating to method of and apparatus for electrical resistance welding of a longitudinal seam in tubing
IPC: B23K11/06
Filed: 1938-09-28
Abstract: 510,648. Electric heating. SESSIONS, F. L. Sept. 28, 1938, No. 28214. [Class 39 (iii)][Also in Group XXII] In electric resistance butt or flash welding the longitudinal seam of a tube by moving the tube progressively between a pair of contact electrodes, such as rollers, connected to a source of impulsive welding current, and engaging opposite sides of the seam, the flow of current from the electrodes around the back of the tube is reduced or prevented by inducing an opposing E.M.F. on the back of the tube. This may be effected by placing a magnetic core in the tube in the vicinity of the electrodes or internal and external cores. One or both cores may carry separably energized electric coils. In the form shown in Figs. 7-9 internal and external cores 6a, 7a are provided. In Fig 25, a longitudinally adjustable bar 44 is secured to a bar 45 on which is mounted the internal magnetic core 6a. Secured to the bed opposite the core is an external core 7f. The internal core carries a two part coil 8c, 8d, the first coil 8c being provided with conductors 74, 75 and the rear coil with conductors 76, 77. The welding electrodes may be connected to a transformer supplied from an auto transformer in one of the phases of a three phase supply. An adjustable auto transformer connected to a second phase is connected to the coils via a reversing switch, variable inductance and condenser, so as to vary the voltage, reactance, and phase relation of the current supplied to the coils. When a two part coil is used the coils may be connected by switches so that they may be arranged in parallel or in series.

Title: Lock valve assembly
IPC: F16K11/20
Filed: 1975-07-04
Abstract: 1463928 Valves CATERPILLAR TRACTOR CO 4 July 1975 [31 Oct 1974] 28354/75 Heading F2V In a locking valve for inclusion in an hydraulic circuit between a control valve 15 and a double acting jack 10, each of two connecting passageways between an end of the jack and a respective connection to the control valve is divided within the valve into a high flow rate flow path 32, 34 and a low flow rate path 33, 35 and in each flow path there is a check valve blocking flow from the jack. Fluid pressure operated means are provided for selectively opening these valves, to permit fluid to flow from the jack, depending upon the pressure at the inlet to the jack which in turn depends upon whether the jack is under positive or negative loading. If the line 25 is pressurized and the jack 10 is under positive loading the inlet pressure in line 31 will exceed the outlet pressure in line 30 and a piston 44 will move to the left to open a check valve 36 in the high flow rate path 32. At the same time a further piston 45 will move to the left to open a ball check valve 76 in the low flow rate path 33. Outlet flow from the jack under positive loading conditions is thus via both flow paths. Should the jack be under negative loading, pressure in the line 30 will exceed that in line 31 and this pressure, acting on the outer end surface of the check valve 36 through passageway 68 which surface has an area equal to or slightly greater than the surface area of the piston 44, will be effective in keeping the valve 36 closed. The effective area of the piston 45 is, however, much greater than that of the wall clock valve 76 which is thus opened but a tapered valve head portion 89 on the piston 45 controls the amount of fluid flowing through the low flow rate path, which also includes a fixed size orifice 55. A piston portion 90 on the valve head of the piston 45 provides a damping action.

Title: Process and apparatus for the production of alkali or alkaline earth metal cyanides
IPC: C10L1/14
Filed: 1956-09-27
Abstract: <PICT:0836823/III/1> Alkali and alkaline-earth metal cyanides are prepared by reacting gaseous hydrogen cyanide, or gases containing hydrogen cyanide, with an alkali or alkaline-earth metal oxide or carbonate, including the bicarbonate, and especially the carbonate, at elevated temperatures, wherein the particles are continuously subjected to individual movements in opposition to the force of gravity throughout the action of the hydrogen cyanide, and are more especially maintained in the freely suspended state, for example in a fluidized bed or on a vibrating conveyer.  The waste gas may be dried and the hydrogen cyanide separated from carbon dioxide by adding it to a mixture of hydrocyanic acid and pentaerythritol.  In the preferred embodiment, sodium carbonate is fed from a hopper 11 to the lower end of a vibrating spiral support in a heatable container 16. A gas containing hydrogen cyanide enters 16 at 17 and moves downwardly in countercurrent to the sodium carbonate.  The partially reacted carbonate leaves 16 at 17 and passes into the bottom of fluidized bed 114, surrounded by heating jacket 113.  Fresh gas containing hydrogen cyanide enters at 112 and 111.  The completely reacted carbonate and the partially exhausted gas leave at 115, and are separated in the cyclone 116, from which the gas is passed to 16 via line 118.  The sodium carbonate may be obtained by calcining sodium bicarbonate, for which purpose waste heat from the cyaniding process may be employed, or the calcination and cyanide formation may be carried out in the same apparatus, for example by calcining in the bottom of container 16.

Title: An electro-mechanical apparatus for the transmission and reception of alarms of fire, and other signals
IPC: G08B25/00
Filed: 1923-11-27
Abstract: 230,144. Trimble, J. Nov. 27, 1923. Fire, police, and like alarm systems and apparatus.-In apparatus for transmitting and receiving fire alarms and other signals by code, a bell is used in combination with a numbered' dial at the receiver and is rung a number of times corresponding to the characteristic signal received and is rung continuously when any one of a number of transmitters fails to act. A number on the dial corresponding to the signal also comes into view. As shown in Fig. 2, the receiver comprises a numbered dial F which is rotated by a weight under the control of an escapement mechanism E, 1. The pawls I are operated by a relay which is intermittently energized by the signal impulses to allow the corresponding number on the dial to appear behind an aperture on the receiver casing. A bell is connected in circuit with the relay and is rung by the signal impulses. Each transmitter, Figs. 5 and 6, comprises a code wheel O which is driven, when a spring controlled push U is depressed, by a weight f, the speed of which is controlled bv a clockwork escapement g. During rotation, the wheel O lowers and raises an earthed arm Q which makes and breaks contact with a line terminal R to send the characteristic number of impulses over the line. Normally, the arm Q is held clear of the wheel O by a projection S on a bolt T which is retained in the raised position by the stem a of the push U, but when the push is depressed, the bolt drops into a hole in the stem a and allows the arm Q to engage the, code wheel. A depression on the code wheel is normally located opposite to a projection on the arm Q, thus providing for a continuous ring on the bell at the receiver in the event of the transmitter failing to revolve when released. If the cord e which supports the weight f breaks, a continuous alarm is also given. A bar W, resting on the top of the bolt T, prevents closure of the door of the transmitter box unless the mechanism has been properly set. A bar W<1> similarly prevents closure of the door unless the mechanism has been fully rewound. The receiver and transmitter are connected by a single line wire the return of the signalling circuit of each transmitter being through earth. An accidental earth on the line thus causes the receiver bell to ring continuously and a breakage in the line does not prevent the transmission of signals. The continuity of the line may be tested by an earthing switch at the receiver. The transmitter may be modified to operate automatically in the event of fire. The push U is held in its normal position against spring pressure by a solder which melts at a low temperature.
