IPC: A61B5/11
Abstract: 105,688. Jorgensen, A. V. C. July 27, 1916. Percussion apparatus.-Percussion sounding- apparatus for use in examining the inner organs of the body is so constructed as to ensure predetermined values of the pressure of the contact member of the body and of the force of the stroke. In the form shown in Fig. 1, the contact member 7 is fitted with spring arms 15 outwardly bent or bevelled at their upper ends 17 which engage slots 18 in a partition 6 so that, on pressing the contact member 7 upwards against the pressure of the spring 9, the arms 15 are spread apart. The arms 15 when moving upwards engage a nut 22 so as to raise the spring striker 20 and on further movement are forced apart so as to release the striker. The striker may be adjusted in length by screwing it through the nut 22 so as to vary the force of the blow and the pressure of the contact member on the body may be varied by compressing the spring 9 by adjusting the stop-ring 10 in the outer casing 3. Figs. 3 and 4 show a modification in which the pressure of the contact member 7 is determined by a coiled flat spring 90, the effective length of which is controlled by an arm 44 carried by a ring 43 mounted so as to be capable of rotation on the casing 3. The striker 21 is raised against its spring by clockwork 31 mounted at the upper end of the casing and released by upward movement of the contact member. The apparatus may be furnished with one or more ear tubes 49 connected to a screen 47 insulated from the casing 3 by a felt ring 48.

IPC: G01P13/02
Filed: 1920-04-19
Abstract: 165,580. Mills, J. G. April 19, 1920. Tell-tale apparatus.-To indicate to a helmsman the direction of the wind relatively to a ship, the wind vane 1 carries a moving contact arm 4 which closes one or other of a series of circuits 13, which may energize electromagnets 11 for actuating an indicating-needle 12, or may light lamps arranged in a circle on the indicating- instrument. A pointer carrying a pilot-lamp is set at the angle at which the wind most advantageously meets the ship, and the helmsman then steers so as to bring the illuminated indicator-lamp opposite the pilot-lamp. The windvane may be so mounted as to be free to rock on a pivot in its own plane so that it finds its level when the ship heels over. It may also have two tails to render it more sensitive to the wind, and its shaft may be provided with a damping-device.

Abstract: 264,050. Barbet, E. A. April 26, 1926. Addition to 224,921. Alcoholic liquids, distilling.-In rectifying alcohol under vacuum, as described in the parent Specification in a column H, H<1> evacuated by a pump P, a preliminary purification of the alcoholic liquid and a separation of the gases is effected in the columns A, B. Vapours from the top of the column A are used as heating agent and are condensed in a tubular boiler G at the base of the column H. The condensate passes to a float chamber g, from which gases rise in a pipe 21 and liquid is forced by a pump I through a pipe 41 into the column B operating under atmospheric pressure. Gases escape from the condenser C, light products pass away through an outlet D, and the purified alcoholic liquid is drawn through a float chamber b and pipe 51 into the column H. The column H, H<1> has a pasteurizing device 52 at the top and is surmounted by a water-cooled condenser J<1>, having a path for the vapours progressively reduced in size as the vapours condense. Amylic and butyric products are drawn off through outlets 7, 8, by pumps M, M<1>, pasteurized alcohol is discharged barometrically through a cooler N<1>, pipe 53, and a safe X, and non-pasteurized alcohol through pipes 12, 13 by a pump M<11>. Final traces of water are removed from the alcohol by passing the alcohol from the safe X into a column O, O<1>. The product passing from the base of this column is absolute alcohol boiling at 78.0‹ C., while the product passing from the top is an azeotropic mixture of alcohol and water boiling at 78.15‹ C., which is returned through a float chamber S to the column H, H<1>. Alcohol vapours drawn off by the pump P are passed into the base of the purifying column B.

Abstract: CrB2 powder is made by mixing electrolytic Cr powder and B powder and heating in a graphite crucible under an atmosphere of H2 for 1 hour at 1600 DEG  to 2000 DEG  C.  CrB2 powder, plus 28 per cent Cr2NiB4 powder is produced by mixing Cr powder, B powder and Ni carbonyl in the correct proportions, mixing, compacting and heating in a graphite crucible under H2 at 1600 DEG  C. for 1 hour.ALSO:Steel and other iron base alloys are protected against reaction with molten aluminium by a coating of CrB2 with 7-50 per cent of Cr2NiB4 sprayed on to the ferrous metal by a flame spray gun having a flame in excess of 3000 DEG C.  The coating metal is prepared by mixing CrB2 powder with 2 per cent carbonyl nickel and 2 per cent resinous binder, ball-milling and extruding to form a rod, the rod being dried at room temperature for 24 hours and sintered on graphite supports for three-quarters of an hour at 1500 to 1700 DEG C.

Title: Improvements in or relating to electric pulse generating apparatus
IPC: H03K5/07
Filed: 1952-05-01
Abstract: 722,204. Pulse-generating circuits. GENERAL ELECTRIC CO., Ltd., ELLIOT, E. W., and HUNT, G. J. May 1, 1953 [May 1, 1952; April 24, 1953], Nos. 11071/52 and 11380/53. Class 40 (6). In a generator of " sine-squared " pulses, an input pulse is arranged to shock excite a resonant circuit, a pulse equal to one half cycle being derived from the resulting oscillation and fed to a square-law device to give the output pulse. A positive-going triggering pulse Fig. 2A is applied to the normally non-conducting valve 2a of a cathode-coupled flip-flop 2a, 2b, Fig, 1, to produce a pulse, Fig. 2B, the amplitude being determined by resistor 4 and the slope of the trailing edge by resistor 5. The pulse is amplified by pentode 6, the amplification being determined by resistor 7. The resulting pulse, Fig. 2C, is applied to resonant circuit 8 to generate the wave, Fig. 2D. The leading edge causes the oscillation to commence with a negative half-cycle, the sloping trailing edge being effective at the commencement of the following negative half-cycle to suppress the oscillation. Due to the diode 12 shunting the path to the grid of valve 13, only the positive half-cycle, Fig. 2E, passes to the control and suppressor grids of the pentode 13 and as the valve is operated on the linear parts of the control and suppressor grid characteristics of the anode current varies as the square of the input voltage, a sined squared pulse appearing at the output terminal, Fig. 2F. The resistors 4, 5 are adjusted to ensure that a second positive half-cycle does not appear across the resonant circuit 8. In a modification, Fig. 3 (not shown), resistor 5 is omitted so that rectangular pulses are generated and applied to the resonant circuit which is shunted by a diode. The negative-going leading edge is thus ineffective due to the diode conducting, but the trailing edges cause a positive-going sine wave to be generated which is suppressed at the end of the first half-cycle. The circuit may be employed in a testing apparatus as described in Specification 722,205, [Group XXXVI].

Title: Improvements in or relating to magnetic regulating mechanism for clockwork mechanism
IPC: G04C5/00
Filed: 1943-07-09
Abstract: 570,187. Clockwork mechanism. STRAUMANN, R. July 9, 1943, No. 11167. Addition to 570,143. [Class 139] [Also in Group XXVI] Means for regulating the speed of a mechanism comprises a disc d, Fig. 1, driven by the mechanism and having secured to it one end of a spring b, the free end of which carries a magnetic mass c. During the rotation of the disc d, the mass c passes near pairs of fixed magnetic poles e, the resultant magnetic reactions maintaining the spring b in oscillation and also controlling the speed of the disc d. Should the spring b fall out of step, the mass c strikes a fixed pin n. This restores the vibrations of the spring so that the mass c may react properly with the magnetic poles e. In a modification, Fig. 4, the spring b<2> oscillates in a plane containing the shaft p driven by the mechanism to be regulated. The fixed poles e<2> are attached to a non-magnetic carrier q on which is screwed a ring r of magnetic material to act as a shunt. The magnetic reaction between the mass and the poles e<2> and hence the regulated speed of the shaft p is varied by altering the position of the shunt ring r. A similar variation may also be obtained by varying the distance between the mass and the poles e<2>.
