Title: Grain size distribution indicator
Inventor: GILLEBAARD SECCO HARMEN
IPC: G01N15/04
Filed: 1966-08-09
Abstract: 1,128,785. Determining grain size distribution. BAGGERMAATSCHAPPIJ BOS & KALIS N.V. Aug. 9, 1966, No.35639/66. Heading G1S. Apparatus for determining the grain size distribution comprises a horizontal tubular housing 1 which is at least partly transparent and has a constant internal cross-sectional area, and through which a stream of liquid can be passed in the longitudinal direction at a constant velocity and which preferably decreases gradually vertically downwardly, a rest zone 5 subjacent to the stream, a supply line 2 for an earth mixture under test and a graduation 10 along the lower edge of the housing. Means 7, 8 are provided for washing away a sample of earth settled in the lower end of the housing. The sample of earth mixture is introduced into the liquid flowing through the housing 1 through the supply line 2. Depending on the grain size distribution, the disintegrating sample will settle in the restricted portion 5 the bottom of which is closed by the wall of tube 7. A settling pattern 9 is formed from which by means of graduation 10 the distribution of grain size can be determined.

Title: Jacking devices
Inventor: WEBB GEORGE HENRY
IPC: B66F1/02
Filed: 1968-07-26
Abstract: 1,200,549. Ratchet jacks. G. H. WEBB. 18 July, 1969 [26 July, 1968], No. 35677/68. Heading B8J. A jacking device, Fig. 1, comprises a housing 10 with side plates 11 incorporating guide means 12 for a screw threaded shaft 13. A bifurcated lever 15 is pivoted by pins 14 on the housing 10 and has a socket 16 for an operating handle. A detent 18 is pivotally mounted on pin 17 on the housing 10 and has a concave screw-threaded surface 18a to engage the shaft 13. A similar detent 19 is mounted diametrically opposite the detent 18 on pin 20 on the lever 15. The detents 18, 19 have respectively secured to them arms 21, 22 interconnected by a coiled spring 23 deformed into a C-shape which acts, in the fullline position shown, to urge the detents into engagement with the shaft 13. If the spring 23 is moved to the alternate position shown in broken lines the detents 18, 19 are urged apart. On the lever 15 are mounted two pivotal members 24, 25 interconnected by a spring 26 which loads them into contact with stops 27, 28 on the lever, their ends constituting resilient stops on which the arms 21, 22 can bear to limit outward movement of the detents 18, 19. With the spring 23 set as shown in full lines and assuming the shaft 13 rests on a foot (not shown) on the ground, actuation of the lever 15 causes the housing 10 to rise carrying a load engaged therewith. To lower the housing 10 and load, the spring 23 is moved to its alternative broken line position and the lever 15 actuated. Fig. 4 shows an embodiment operating essentially as above but provided with a housing 30 with a spigot part 34 for engaging a socket on a vehicle jacking system. Detents 38, 39 are loaded by a torsion spring with arm 41 connected to the detent 38 at 42 and with arm 43 bearing on an abutment 44 on the detent 39. A further torsion spring 46 is connected to lever 36 and also bears on the abutment 44. This arrangement causes the housing 30 to rise up shaft 33 when the lever 36 is actuated. To lower the housing 30 arm 43 is disengaged from the abutment 44 and limb 45 engaged against the opposite side of the abutment 44 and the lever 36 actuated.

Abstract: 435,527. Leading - in conductors for electric incandescent lamps. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Peters, L. R.; 10716, Edgepark Drive, Garfield Heights, Ohio, U.S.A.) Dec. 19, 1933, No. 35745. Void [Abridged as open to inspection under Sect. 91 of the Acts, June 25, 1934]. [Class 39 (ii)] Electrical connection to electric lamps or similar devices is made by providing an extension of the bulb with a pocket containing a mass of easily fusible metal in which both the outer end of the leading-in wire and the end of the external conductor are embedded. In a double-ended electric incandescent lamp for series connection, as shown, the lead 13 is sealed into the extension 16 of the bulb. Its outer end extends into the pocket 17 which contains a mass of solder. The end of the external conductor 18, which has a metal collar 20 clamped to the insulation, is embedded in the solder. To ensure a firm joint with the solder the metal collar is crimped at 22. After the joint has been made the rim 23 of the pocket may be drawn down to hold the mass of solder firmly in the pocket 17. The other end of the tube serves for exhaustion and is sealed off by providing the wire 14 with a bead of soft glass 24 which is fused into the end 12 by heating externally, the pocket 17 being similar to that at the other end. In a modification, the leading-in wire is forced to the bottom of the pocket which is half-filled with solder, contact being made by insertion of a pin into the pocket.

Title: Improvements in or relating to electronic circuit arrangements for high-frequency signals
IPC: H03F1/44

Abstract: 1,048,177. Transistor switching circuits. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Aug. 23, 1965 [Aug. 26, 1964], No. 36056/65. Heading H3T. A transistor whose emitter-collector path is in series with a transmission line for switching purposes as in Specification 779,884 is compensated for undesired transmission through its base-emitter capacitance when turned off, by a tapped inductance 17, 19 so that the signal voltage induced in winding 19 is fed to the base through capacitor 10 to be equal and opposite to that passed through the baseemitter capacitance. When two such circuits are connected to a common output line (Fig. 3, not shown) the inductor 17, 19 of each input circuit and the common inductor 18 of the output circuit are each tuned to the operating frequency, e.g. the 11À096 Mc/s. group pilot frequency in a telecommunication system. The output impedance of each switching arrangement can then be adjusted separately by detuning each input circuit while eliminating the imaginary part of the output impedance by the compensating network. For two-way transmission (Fig. 4, not shown) a symmetrical transistor is used, with a compensating network on each side of it.
