Title: Improvements in magnetic bistable device
Inventor: KAUFMANN HENRY WILLIAM
IPC: H03K3/45
Filed: 1956-11-19
Abstract: 818,822. Magnetic amplifiers. SPERRY RAND CORPORATION. Nov. 19, 1956, No. 35325/56. Class 40 (9). A trigger pair comprises two saturable magnetic cores I and II, each of which has an input winding 22 and a power winding 21, a load R3 being energized over the power winding provided that the input winding is not energized, the output of the power winding on each core being connected to feed the input winding of the other core. A power source producing a square waveform is applied to terminal 1 to energize the power winding of core I over a rectifier D4; a similar source, but in antiphase is applied to terminal 2 and energizes the power winding of core II, see Fig. 6. Positive halfcycles of the power sources drive the cores to saturation in one direction while positive pulses applied to the input windings during negative half-cycles of the power sources drive the cores the saturation in the opposite direction. If for each core no input pulse is applied. during a negative half-cycle, the subsequent positive half-cycle of the power source finds a low impedance in the power winding and produces an output acrossload R3. If an input pulse is applied the power winding presents high impedance to the subsequent positive half-cycle and no output appears across the load R3. If core I produces an output this is applied as an input to core II to suppress the output of core II. As core II produces no output, core I receives no input and continues to produce output during positive half-cycles of its power source. If an input pulse is applied to core I, during the half-cycle T6, T7, as shown in Fig. 6, by means of an input terminal 4, the output of core I is suppressed in the next half-cycle so that core II is not reset. Subsequent positive half-cycles applied to core II therefore produce an output which is applied as an input to core I to hold the output of core I suppressed. Core II continues to produce an output until an input is applied over a terminal 6 to suppress the output and automatically re-establish that of core I. In Fig. 5 a resistance R2 and rectifier D5 are provided for each core to block the input windings during positive half-cycles of the power sources and open them to conduction during negative half-cycles. Sneak pulses induced in each power winding are suppressed by a resistance R1, negative potential source V2, and a diode D3.

Filed: 1954-12-08
Abstract: 755,810. Mechanical wheeled toys. RICO, SOC. ANON. Dec. 8, 1954, No. 35535/54. Class 132(3) A toy comprises a figure which appears to be chased and caught by a second figure. As shown, a small fish figure is provided With a spring driving mechanism which is wound by unwinding a thread 7 from a bobbin 2, the thread being attached to a larger second fish figure having no driving mechanism. The small figure is provided with a slide member 9 having its rear end upturned, and a tail portion 22 is rounded for sliding engagement with a portion 15 of a pivoted upper jaw of the larger figure. A slide member 19 for engagement by the slide 9 is provided in the base of the larger figure and has the free end of the thread 7 7 attached to its inner end. After the driving mechanism is wound, the thread 7 becomes rewound on the bobbin and the larger figure is thus drawn to the small figure as the latter travels forwardly and eventually passes into the larger figure which has its upper jaw raised by the tail of the small figure. The sliding engagement of the members 9, 19 causes the running wheels of the small figure to be raised clear of their running surface and the resulting acceleration of the driving mechanism produces a momentary speeding up of the small figure as it passes into the larger figure, the upper jaw of the larger figure then falling to its closed position. The figures may comprise a cat and mouse, a dog and a rabbit or a lizard and an insect.

Abstract: 1,255,766. Lubricating; hydrodynamic brakes. ALFRED TEVES G.m.b.H. 23 July, 1970 [30. July, 1969], No. 35702/70. Headings F2A and F2E. The seals and bearings of a shaft which passes into a housing having a chamber containing high, low or normal pressure. (e.g. a hydrodynamic brake) are provided with a system for preventing the loss of lubricant when the chamber is evacuated. A rotor 31 of a hydrodynamic brake is supported in bearings 46. Vanes 32 are connected to the rotor and rotate in a chamber 33 in a housing 34. To brake the rotor 31, pressure medium is fed into: the chamber 33, and the chamber is evacuated when the brakes are not applied. When the pressure medium is pumped into the chamber some passes past the one-way sealing ring 8 into the space 37 and lubricates the bearing. Escape of lubricant from the space is prevented by another one-way sealing ring 9. On evacuation of the chamber 33 the pressure medium in the bearing chamber 37 is partially allowed to escape through a valve 44 but the valve prevents such escape of pressure medium as would leave the bearings unlubricated. The  force of the spring 51 on the closure member 50 is such that the reduction of lubricant pressure is the required amount.

Title: Improvements in the methods and means for producing active charcoal or for re-activating spent charcoal
IPC: C01B31/08
Filed: 1932-12-17
Abstract: <PICT:0411918/III/1> In a continuous process for the activation or reactivation of carbon wherein the activatinggases and the carbonaceous material move in counter-current, the resultant gases are passed through a layer of glowing fuel so that the aqueous vapour content is converted to water gas thus increasing the calorific value of the gases.  The layer of glowing fuel may be the fuel on the grate of the furnace serving to heat the exterior of the activating retorts or it may be constituted by the hot charcoal in one of the retorts. To increase the amount of water gas produced, an amount of steam in excess of that required for activation purposes is supplied together with supplementary air, and the gases from one activating retort may be passed to a number of zones in a second. In the case of a battery of retorts, these are operated in series and the gases are passed in counter-current with the carbonaceous material, except as regards the last retort through which they pass in the same direction as the material and are led to the furnace.  Retorts 1 . . 4 are arranged vertically in a brick structure a through which heating gases from a furnace b pass in the direction of arrows c, baffles d being provided for this purpose.  Conveyers f feed the carbon to be treated which is withdrawn at g.  To the retorts 1, 2, 3 the activating-gases are supplied by a pipe h to the lower hot end and to the upper cold end of the retort 4 by a pipe h<1>.  Hot gases leaving the activating zone of the retort and serve to heat and dry the material entering at the top and the moisture laden gases are conveyed by a pipe j to the lower end of the retort 2, any air necessary to maintain the temperature being introduced by a valve j<1>.  From the upper end of the retort 2, the gases may be fed by a pump n to different points in the retort 3 by pipes o<1>, o<2>, o<3>, excess of gas being passed by a pipe t to the lower side of the grate b<1> of the furnace.  From the upper end of the retort 3, the gases pass by a pipe p to the upper end of the retort 4 and move down with the activating-gases so as to pass through the glowing carbon at the base of the retort whereby all the moisture content is converted to water gas and conveyed to the furnace by a pipe s.

Title: Improvements in or relating to rock drills
IPC: E21B19/081
Filed: 1946-12-03
Abstract: 630,021. Percussive drills. BROOM & WADE, Ltd., and HAUSFELDER, L. Dec. 3, 1946, No. 35823. [Class 124] The feed of a rock drill is automatically controlled in accordance with the resistance to drilling by means of a coupling between a feed screw and a reversible air motor driving it, the coupling comprising two interengaged rotary members one of which may be moved axially against a spring on changes in torque in the feed screw and which has a connection to a speed control for an air motor. As shown an air motor drives a screw 10 through a worm 12 and gear 11, the worm 12 being movably mounted on splines 17 against a spring 18. An increase in torque in the screw 10 produces axial movement of the worm against the spring and, by means of a double ended lever 64 one end of which operates in a groove 28 in the worm, an air valve 21 is closed against a spring 24 thus reducing the speed of the air motor. In a modification, Fig. 2 (not shown), a collar, having a quick, four start thread co-operates with a nut acting against a spring to operate the air valve. In a further modification, Fig. 3 (not shown), a pinion with an internal helical thread moves a lug in a slot in a hollow shaft against a spring to operate the air valve. There is also described a pendulum compensator for operation of the drill in different positions.
