Title: Improvements in or relating to the Testing of Ball Bearings
IPC: G01M7/00
Filed: 1966-08-01
Abstract: 1,151,745. Testing ball bearings electrically. FAFNIR BEARING CO. Aug.1, 1966 [Aug.2, 1965], No.34427/66. Heading G1N. In a ball bearing testing machine the inner ring of a bearing B, Fig.3, is held firmly on a motordriven arbor 10 by a slidable cylindrical member 11, and the outer ring is subjected to alternate axial thrusts in opposite directions by annular axially slidable members 20L, 20R, the vibrations of the outer ring being measured by a Piezoelectric transducer (PU, Figs.1, 2 not shown) The arbor 10 and member 11 carry a resilient flanged sleeve 10a, 10b, and a resilient ring 11a, respectively. The member 11 retracts to allow the tested bearing to be pushed off the arbor by one side thrust member 20L, and to permit a fresh bearing carried by a bearing carrier Fig. 5 (not shown), to be brought by transverse movement into axial alignment with the arbor ready to be pushed on to the arbor by the other of the side thrust members 20R. When the fresh bearing is in position, the transducer (PU) is brought into contact with the outer ring thereof. The various moving parts of the machine are motivated by pneumatic or hydraulic means under the control of solenoids and a relay circuit Fig.19 (not shown). When a bearing has been subjected to both side thrust tests, and is ejected, it falls into a container 22, from which it passes to an "accept" or "reject" exit (not shown) controlled by the measured magnitude of vibration. The rejection of a bearing may occur before the end of a cycle if an excessive vibration is detected. The mechanical features of the machine are described in some detail.

Patent GB-735019-A (GB)
Title: Improvements in method of and apparatus for making patterned tufted pile fabric
IPC: D05C15/18
Filed: 1953-12-15
Abstract: 735,019. Tufting; tufting machines. CARD, J. L. Dec. 15, 1953 [Dec. 24, 1952], No. 34879/53. Class 112. Tufted fabric with pile of a required length is produced by a needle projecting loops of yarn through a base fabric with a uniform stroke, the yarn being fed to the needle at a rate such that for each stroke a pile loop is formed having a length less than the maximum possible length; different rates of feed may be used in different parts of the fabric, to produce pile of different depth. Fig. 10 shows the formation of loops in a machine with a needle 16 of constant stroke and a looper 19 which holds the loop of yarn while the needle withdraws, the loop then being released by the looper; if the yarn is fed to the needle at a sufficient rate, loops L<SP>2</SP> of maximum length are formed, but if the rate of yarn feed is reduced a loop L<SP>3</SP> of the same length is formed by the needle but part of the yarn for this loop has to be drawn from the preceding loop, which is therefore drawn up to a length such as is shown at L<SP>1</SP> the loop L3 being similarly drawn up on the formation of the next loop. In the multineedle machine shown in Fig. 4, yarns Y are fed to separate groups of needles by corresponding pairs of rollers 33, each pair being selectively connectible to clutches rotating at different speeds, so that the length of the loops being formed by each group of needles may be chosen by engaging the appropriate clutch. The rollers of each pair are geared together, and one of them is connected to the driven elements of two clutches, the driving elements of which are constantly rotated at different speeds, so that each pair of rollers can be driven at either of two speeds, which is selected by actuation of a switch 72 selectively energizing one or other of the clutches. The switch 72 is actuated by lugs 70 on a pattern chain 65 of a length corresponding to a complete repeating unit of the required pattern, a separate switch and chain being provided for each group of needles; a chain 65<SP>1</SP> of a length corresponding to a complete rug similarly actuates a switch which overrides the other switches to control all the needles for producing the end portions of the rug. A single yarn-feed roll with a suitable surface may be used instead of a pair of rollers. The needles 16 are carried by a bar 15 reciprocated vertically by eccentrics 11 on a main shaft 5, from which are driven the pattern chains and the clutches for the yarn-feed rollers and also an oscillating shaft 20 carrying the loopers 19. The needle-bar 15 carries a parallel bar 79 which engages the yarns to draw up the previously-formed loops when required by a slow yarn feed. The base fabric 21 is fed from a roll 22 by roller systems 23, 24 driven from the main shaft 5.

Abstract: 791,353. Colour photography. KODAK, Ltd. Dec. 7, 1955 [Dec. 20, 1954], No. 35055/55. Class 98(2) A colour coupler is incorporated in a gelatino silver halide emulsion by dissolving it 'in a low-boiling water-insoluble organic solvent, dispersing the solution in aqueous gelatin solution, removing substantially all organic solvent from the resulting dispersion, separatety dispersing in aqueous gelatin solution an oil former as defined in Specification 541,589 and then mixing the two dispersions with a gelatino silver halide emulsion to form a dispersion in the emulsion of liquid particles of the coupler and organic crystalloidal material. The dispersions have a low ratio of crystalloidal material to coupler. The low-boiling solvent may be nitromethane; nitroethane; methyl, ethyl, propyl, or butyl acetate; ethyl or butyl formate; or low-boiling water-insoluble solvent as described in Specification 791,219. The crystalloidal material may be di-n-butyl phthalate or any of the oil-formers described in Specifications 541,589 or 791,219. A number of suitable couplers are specified. In Example 1, an ethyl acetate solution of 1 - (2<SP>1</SP> : 4<SP>1</SP>: 6<SP>1</SP> - trichlorophenyl) - 3 - [3<SP>11</SP> - (2<SP>111</SP> : 4<SP>111</SP> - di - tert. - amylphenoxyacetamido) - benzamido] - 5 - pyrazolone is added to an aqueous solution of gelatin containing Alkanol B, the mixture is passed through a colloid mill 4 times, chilled, shredded, and dried on a stainless steel screen. Di-nbutyl phthalate is added to an aqueous solution of gelatin containing Alkanol B, and the mixture is passed through a colloid mill and filtered through a silk screen. The dried coupler dispersion is added to water containing saponin and, after soaking, the mixture is heated to 40‹C, the di - n - butyl phthalate dispersion is added, and the resulting mixture is added to a gelatino silver halide emulsion which is then coated and dried. In example 2, the procedure is similar using as the coupler 2 - (a - 2<SP>1</SP> : 41 - di - tert. - amylphenoxybutyrylamino) - 4 : 6 dichloro - 5 - methylphenol and, in place of the di - n - butyl phthalate, tri - o - cresyl phosphate (in ethyl acetate solution). In Example 3, the procedure is similar using as coupler N - (4 - benzoylacetaminobenzene sulphonyl) : N - (γ - phenyl - n - propyl) - p - toluidine (in methylisobutylcarbinol) and, in place of the di - n - butvl phthalate ethyl sebacate.

Title: Improvements in or relating to delay line arrangements
IPC: H03H11/26
Filed: 1958-11-04
Abstract: 842,437. Delay-lines. TELEFUNKEN G.m.b.H. Nov. 4, 1958 [Nov. 27, 1957], No. 35455/58. Class 40(8). A delay line is combined with means responsive to an applied control voltage for varying the reactances of series and shunt reactance elements included in said line to vary the delay time thereof, the relation between the variation of the reactances of the series elements and that of the shunt elements being such that the surge impedance of the line is maintained substantially constant over the range of delay time variation. The series reactances are preferably inductances consisting of coils wound on magnetic cores the magnetization of which is varied by subsidiary coils. The shunt reactances are preferably semi-  conductor diodes, e.g. Zener diodes, the capacitance of which is dependent on an applied D.C. voltage. Alternatively, condensers having dielectrics whose dielectric constant depends on the applied field intensity, e.g. ferro-electric substances such as barium titanate, Seignette's salts, and certain phosphates, may be used, or idle current valves or transistors. The line shown comprises a number of # sections each consisting of a series inductance I and two shunt condensers 2. Each inductance 1 has a ferromagnetic core 3, preferably of ferrite, with a magnetizing winding 4. Input and output terminating resistances 6 and 9 are connected to input and output terminals 5 and 8 and to the line through blocking condensers 7 and 10. A control unit 11 supplies direct current to the windings 4 and. direct voltage to the condensers 2 in response to a control voltage applied to an input terminal 12 so that the input and output surge impedances of the line always equal the values of the resistances 6 and 9 respectively. The delay line may alternatively comprise a number of bridged T sections (Fig. 2, not shown). A suitable control unit is described in combination with a delay line in which the series inductances have a third winding to compensate for the effects of stray leakage and capacitance, and the shunt reactances are Zener diodes (Fig. 3, not shown). To avoid interaction in cases where the control signal contains frequency components within the frequency range of the signal to be delayed, a symmetrical delay line may be employed with a pushpull voltage supply to the Zener diodes (Fig. 4, not shown) or a symmetrical supply via T- connected sets of resistances (Fig. 5, not shown). Alternatively, undesired action of the control signal on the main signal in an unsymmetrical delay line may be prevented by utilizing a compensating voltage derived from the control unit (Fig. 6, not shown).
