Abstract: 1,129,233. Electrical connectors. AMP Inc. 17 May, 1967 [1 June, 1966], No. 22809/67. Heading H2E. A connector comprises a channel-shaped conducting ferrule having pairs of tongues 8a, 8b and 10a, 10b struck from its base 4, and sidewalls 6 with portions 19 and ears 22 which, on crimping, force insulated wires 15 into slots 12 in the tongues, the slot edges cutting through the insulation to contact cores 13. A waterrepellent insulating film 24 of ionomer resin or other plastics material is heat bonded to the outer surface of the ferrule and extends beyond the sidewalls and ends of the ferrule as shown at 26 and 25 respectively. A second insulating film 28 is bonded to film 24 and encloses the rest of the ferrule. On crimping, the film 28 is ruptured by the edges of slots 12, and moistureresistant material 40, which may be of polyisobutylene impregnated polyurethane foam or other plastics material, flows through the ruptures to seal the connections between the wire and tongues and the wire ends (41). A seam (39, Fig. 4, not shown) is formed as a result of crimping and is sealed by engagement of portions of the film 28. The film 24 may be a laminate or the connector may be covered with plastics material by fluid-bed coating methods or by spraying.

Abstract: 164,990. Salzmann, E. Aug. 6, 1920. Inkstands.-An ink receptacle, especially adapted for inking draughtsmen's pens, is provided with two openings, one in the top and one in the bottom, adapted to be closed or opened simultaneously by valves mounted on a common stem. The receptacle a, provided with a sediment recess p, is mounted on a stand b formed with a saucer-shaped foot c. The upper valve. f consists of a disc of leather or rubber held in place on a screw-threaded part of the stem g by nuts. The lower valve consists of a swelling e of the stem g covered with a rubber or like sleeve, and acts in a conical opening n in the base of the receptacle a, only small play being left between the point m of the stem and the mouth of the opening n. A lever i, pivoted to the upper end of the stem g and in a block h on the top of the receptacle, is held in position to keep the valves normally closed by a spring k, and a screw l carried by the lever i limits the play of the lever and the opening of the valves.

Class 120(2) A doffing device for spinning and like machines comprises two parallel shafts, means for raising and lowering the shafts and turning them about 180 degrees, members carried by one of the shafts for removing full cops and members carried by the other shaft for carrying and positioning empty cops, all the members being provided with flexible elements adapted to apply pressure to the cops. The copremoving members comprise rings 11 containing gripping devices 12, so that, when the rings 11 are raised by the handle 6 through a rack and pinion 2, 3, swung through 180 degrees by the handle 13 to locate them immediately above the spindles 10 and then lowered to embrace the cops 14, they will grip the cops firmly. They may then be raised, swung through 90 degrees and lowered for manual removal of the cops 14. The tube positioning members consist of cylinders 19 provided with springs 22 for gripping coptubes 21 that are placed in the cylinders 19 from above. When the cylinders 19 are rotated through 180 degrees and the tubes 21 lowered on to the spindles 10, they remain on the spindles because the latter exert a stronger grip on them than the springs 22. In order to facilitate the release . of the full cops from the spindles, levers may be provided to strike against the base of each tube. All the spindles on one side of a machine may be doffed simultaneously, or only a half of them; with the latter arrangement, the operating elements. may be duplicated at each end of the machine.

They are connected to terminals 44, 48, to which supply potentials are supplied, via variable impedances, which in the embodiment comprise further field-effect transistors P60, N62, jointly controlled at terminal 50 such that the potentials at the terminals 20, 24 vary in the same direction. The output is thus the sum of the signals at terminals 10 and 22.

The potential at the point 50<SP>1</SP> is also applied to control terminal 50<SP>11</SP> of the second amplifier 72, to the input terminal 1011 of which a signal input is applied, thereby biasing it also to the centre of its linear characteristic. The control may be improved by connecting a further amplifier between the output terminal (22<SP>1</SP>) of the amplifier (70) providing reference bias and its control terminal: by using a differential amplifier offset can be introduced by applying a bias to its second input terminal (Fig. 6, not shown). In an arrangement comprising a number of complementary FET amplifiers in cascade, either a common pair of bias-determining complementary FETs may be used (Fig. 7, not shown) or each amplifier stage may be provided with a pair under a common control (Fig. 8, not shown).

At the entry the leading wheels of a vehicle are run on to the supports 13 and, when they contact the stops 29 thereon, move the supports along the platform. During this movement the rollers 18 are guided in channels 19 to lift the chocking members 17 from the inactive (Fig. 4) to the chocking (Fig. 3) position. When the vehicle is fully on the platform, the lever 34 is operated to enter a pin 32 in one of the apertures 33 on support 33 and is then locked by the interengagement of latch members 36 and 39.

[Also in Division G2] In an arrangement where the phase difference between an emitted modulated light beam and the beam returned by a distant object is used as a measure of its distance, three modulating frequencies are employed successively, a basic frequency corresponding to a wavelength of 10 metres in air at N.T.P. or a multiple thereof, a frequency 10<SP>n</SP>/10<SP>n</SP>1 or 10<SP>n</SP>1/10<SP>n</SP> and a frequency of 10<SP>m</SP>/10<SP>m</SP>1 or 10<SP>m</SP>1/10<SP>m</SP>, the last named frequency being used to effect a correction in the distance determined by the first two and n being equal to m + 2. The phase difference may be determined by the comparison of the detected returned signal with an electrical signal modulated in phase with the emitted beam or both beams may be detected and the individual outputs compared. Either path may include and adjustable optical delay line whereby a desired phase difference between the detector outputs may be obtained and the setting of'the delay line may be used to indicate the distance. A gas laser may be used as a source and its beam may be fed to a combined modulator divider in which a #/4 plate is followed by a pair of Pockel type electro-optical crystals and a birefringent crystal of for example sodium nitrate. The optical delay line, Fig. 3, comprises a pair of opposed spherical concave mirrors 21, 22 thus radii of curvature and the angle of beam incidence being such that the points of incidence of the beams reflected back and forth lie on circles on the mirror surfaces. Take-off of the beam after a number of traverses is by way of mirrors 24-27, 24 and 25 being rotatable around the axis in steps and 26, 27 being movable along the element axis by means of a screw. The amount of delay is indicated by the sum of the readings of dials 29 and 30. The detector may comprise a photomultiplier in which one signal modulates the cathode circuit, a synchronous demodulator using Kerr cells, or photo transistor, photo diode. The manner of measuring and correcting is exemplified, a mathematical analysis being included.

Filed: 1930-08-08
Abstract: <PICT:0366905/III/1> A self-reducing resistance consists of tellurium formed into a solid body, preferably by the simultaneous application of heat and pressure.  Powdered tellurium is placed in a tapering cylindrical bore 15, as shown in the Figure, in a mould 14 of fused quartz resting on a base 16 of fused quartz, the bore 15 increasing in diameter from the top to the bottom.  An iron terminal screw 12 is placed in a recess in the base 16, a similar terminal 11 being inserted in a plunger 17.  The mould 14 is heated to a temperature slightly below the melting-point of tellurium, pressure being applied to the plunger 17 so that the volume of the powdered tellurium is reduced to about one-half, the terminals 11, 12 being firmly embedded in the tellurium.  The base 16 is then removed and the resistance unit forced out of the bottom of the mould.  Other forms of mould, e.g. a split mould, may be employed. Alternatively the tellurium may be melted and cast, or the powdered metal may be cold pressed, and then sintered.
