Title: Methods of and Apparatus for Profiling Cylindrical Workpieces
IPC: B21H1/18
Filed: 1967-08-11
Abstract: 1,195,413. Rolling; making roller bearings. gudgeon pins and Allen bolts. ROTARY PROFILE ANSTALT. 11 Aug., 1967 [17 Aug., 1966; 19 Aug., 1966; 15 Nov., 1966], No. 37007/67. Headings B3A and B3M. A method of rolling solid cylindrical workpieces between the relatively rotating walls of a throat which are progressively moving towards each other is characterized in that the workpiece is restrained from spreading axially during the rolling. The throat may be formed between two or three co-operating rolls, Figs. 7 and 9 (not shown), and in the later case one roll (34) is progressively moved towards the other pair to narrow the throat. In both these embodiments the workpiece must be restricted from axial spread. In a further embodiment the workpiece 10 is rolled between a C-frame 36 and a roller 26. The throat 28 is arranged to progressively narrow. Plungers 50, Fig. 13, are mounted in cages 15 at each side of the workpiece and biased against the workpiece by cam tracks 48 on the C-frame. The tracks 48 diverge as the workpiece moves along the throat to allow axial spread of the workpiece. In a similar embodiment each workpiece is rolled between a C-frame and a pair of rolls 44, Fig. 12, mounted on the inner roll 26. Axial spread of the workpiece is similarly controlled by plungers (50), Figs. 14, 15 (not shown). In another embodiment, Figs. 16-19 (not shown), the cylindrical workpiece (10) is rolled between a C-frame and a roller and restrained axially by flanges (60) on the C-frame. Various shaped profiles may be rolled and a further embodiment, Figs. 20-24 (not shown), has shaped rolls to form four zones (60), (62), (64), (66) on the workpiece. One end of the workpiece is made to flow into a splined sleeve (78) and restrained axial by a plunger (90) whereas the other end of the workpiece flows into a toothed ring (82) and a recessed ring (84) to form teeth and a flange (72) on that end. A socket (74) may be formed in this end of the workpiece either by a stylus (88), Fig. 21 (not shown), or by rollers (94), Fig. 24 (not shown). The workpieces may be rolled so that voids form in the workpiece to save material. Articles such as rollers for roller bearings, Figs. 25, 27 (not shown), or an Allen bolt, Fig. 28 (not shown), or a gudgeon pin, Fig. 29 (not shown), may be produced. The workpieces are preferably rolled hot to facilitate flow but may also be rolled cold.

Abstract: 1,201,763. 763. Fluid oscillators. JOSEPH LUCAS (INDUSTRIES) Ltd. Nov. 15, 1967 [Aug. 18, 1966J, No.37034/66. Heading G3H. A fluid pressure oscillator generates pulses in response to the vibration of a cantiliver leaf spring 18 and at a frequency corresponding to the resonant frequency of the spring assembly. A mass 17 Fig. 1 carried at the free end of the spring has blades 15, 16 which alternatively block jets 13, 14 fed by a constant pressure supply 10. The resultant build up of pressure behind the blocked jet 13 produces a pulse in the associated output line 23 and also in pulses the spring via jet 21 to move it into a position to block jet 14 whereupon the cycle is repeated. Fig. 2 (not shown) illustrates a similar arrangement in which jets (25, 27) alternately feed receivers (26, 28) which are connected to the output lines and spring impulsing jets. In another embodiment Fig. 3 the spring is impulsed by jet 34 impinging on shoe 33, and the output pulses are generated in a single outlet 38 in response to movement of blade 35 relative to jet 36. In a further embodiment Fig.4 (not shown) the arrangement of Fig.3 is modified by dispensing with shoe 33 and impulsing the spring by fluid which issues from the vertical limb of an L shaped bore (39) in mass 17 when the horizontal limb of the bore is aligned with an input jet (40).

Filed: 1976-09-09
Abstract: 1536930 Ultrasonic inspection systems SRI INTERNATIONAL 9 Sept 1976 [6 Nov 1975] 37419/76 Heading G1G In an ultrasonic system for examining the interior of objects, the object 18 is supplied with a broadband ultrasonic signal and the echo signals from discontinuities within the object are converted to electrical signals which are filtered in a bandpass filter 36 having a transmission factor versus frequency characteristic which is variable in accordance with the depth within the object of the discontinuity from which the echo signal is reflected. Ultrasonic pulses are transmitted to the object, such as a heart in a living body, from a transducer 10 via an acoustic lens 16 mounted on a movable platform 48 within a container 12 filled with water. A scanning mechanism 50 is provided with a mechanical linkage 52 for moving the platform 48. A timing and control unit 26 repeatedly switches on a signal source 20 to enable the transducer to supply pulses of ultrasonic energy and an amplifier 28 is gated on between the pulses to receive the echo signals from the object. The attenuation of the echo signals increases as the depth within the object from which they were generated increases, whilst the centre frequency decreases as this depth increases. To maintain the sensitivity of the system for increasing depth of the echo signals, the gain of an amplifier 34 is increased with time by a generator 38 whilst a generator 40 adjusts a parameter of the characteristic of the filter 36 as the time of the received echo signal increases. The parameter which is adjusted may be the passband, the centre frequency, the high or low frequency cut-offs or a combination of these parameters. The processed echo signal is supplied to a cathode ray tube display 46.

Abstract: 818,669. Cathode-ray tube circuits. MURPHY RADIO Ltd. Dec. 22, 1955 [Dec. 24, 1954], No. 37429/54; Class 40 (7). [Also in Groups XL (a) and XL (b)] In a colour television receiver simultaneously available (different) colour signals are supplied sequentially to the control electrode of a single gun colour picture under the control of indexing signals generated by the response of the tube screen to the scanning electron beam and means are also provided for correcting colour distortions due to lack of linearity in the scanning waveform and due to the departure of the screen from a spherical form having the electron gun at the centre. The indexing signals are generated in. known manner and may utilize the direct impingement of the scanning beam on a grid electrode associated with the screen, the effect of secondary electron emission on such grid or, when the grid itself consists of light producing phosphors, the variation in light from the back of the screen to produce the required signals in a photo-electric device. Known arrangements of such screens are described with reference to Figs. 1 to 4 (not shown) the indexing signals produced by any of the above methods being employed to control in a discriminator circuit, the frequency of an oscillator from which, via a phaser circuit, sequential gating signals are derived and employed to gate the colour signals to the control electrode of the tube in synchro. nism with the scanning of corresponding colour phosphor strips in the tube screen (Fig. 5, not shown). To correct for small departures of the line scanning waveform from linearity (i.e. those which cannot readily be corrected in the scanning generator) a low-resistance coil 28 (Fig. 6) is magnetically linked with the line scanning coils 26 and the voltage induced in it supplied by means not shown in Fig. 6 to the discriminator 25 which controls the frequency of the oscillator 11. To correct for variations in the linear velocity of the scanning spot across the tube screen, due to the flatness of the latter, the line deflecting coils 26 are supplied (by means not shown) with a waveform which is an integral of the normal sawtooth deflecting waveform and to compensate for the effect produced by this in the discriminator via coil 28 a correction voltage derived by integrating in 31 the output of the sawtooth waveform generator 29 is supplied to the oscillator 11. Also, due to the screen flatness, the length of the electron path from the tube gun to the screen varies with the angle of deflection and the effect of this is corrected by inserting a variable delay device 32, the delay of which is controlled in accordance with a function of both the line and frame deflecting waveforms, between the oscillator 11 and the phaser circuit which controls the sequential gating of the colour signals. Specifications 511,600, [Group XL], 663,041, [Group XL (a)], 700,453, 700,454, 705,752, 736,005 and 790,219, [Group XL (b)], are referred to.

Filed: 1928-12-19
Abstract: 325,918. White, A. E., (Delco-Remy Corporation). Dec. 19, 1928. Turning-gear.-In an electric starter comprising a pinion 25 slidable and rotatable on the shaft 23 of the starting motor and automatically demeshed from the engine gear 21 when the engine starts, a sleeve 30 actuated by a manually operable sleeve 46 for moving the pinion into mesh with the gear 21 before the starting motor switch is closed, and means for automatically disconnecting the sleeve 46 from the sleeve 30 after the pinion has meshed with the gear 21 and before the engine starts, the sleeve 30 is adapted to rotate the pinion whilst pressing it yieldingly against the gear 21 in case of abutment of the pinion and gear teeth. As shown, the pinion 25 is mounted on a smooth portion 26 of the shaft 23 and the sleeve 30 is weighted at 30<a> and threaded on helical splines 31, and drives the pinion by means of straight splines 32, 33. A compression spring 34 separates the sleeve 30 and the pinion, the separation being limited by a wire ring 36 on the hub of the pinion. The movement of the sleeve 30 and pinion towards the gear 21 is effected by a lever 40 actuated by a pedal 60 and having a stud 43 engaging an aperture 65 in the sleeve 46, which is secured to a disc 44 sliding on the shaft 23 and bearing against the end of the sleeve 30. On depressing the pedal 60, the stud 43 bears against a slightly inclined face 67 of the slot 65 and moves the sleeves 46, 30 and the pinion 25 axially on the shaft 23. If the teeth of the pinion abut against those of the gear 21, the continued movement of the sleeve 30 along the helical splines 31 compresses the spring 34 and turns the sleeve 30 and pinion 25 until the latter is in meshing position- The lever 40 engages a switch plunger 82 and switches on the starting motor. While the engine is being cranked, the friction between the sleeves 30, 46 rotates the sleeve 46, and the engagement of an inclined face 93 of the slot 65 with the stud 43 effects the axial withdrawal of the sleeve 46 from the sleeve 30. Friction between the sleeves 30, 46 is ensured by a spring- pressed plunger 55 and a friction plate 53. When the engine starts, the sleeve 30 and pinion 25 are axially withdrawn from the gear 21 by the action at the splines 31. On the release of the pedal, the lever 40 is returned to its initial position by a spring-pressed plunger 64, when the stud 43 engages the end 68 of the slot 65 and the disc 44 bears against a floating brake plate 70 and cork disc 71. Any tendency of the sleeve 30 to rebound towards the pinion 25 is hindered by reducing the diameter of the helically splined part 31 of the shaft between shoulders 23<a>, 23<b>.

Abstract: Polyamides may be prepared by heating mixtures of <FORM:1112395/C3/1> and <FORM:1112395/C3/2> with dicarboxylic acids or esters or chlorides thereof.  Acids specified are adipic, sebacic, decane dicarboxylic, suberic, terephthalic, cyclohexane dicarboxylic and pyridine dicarboxylic acids.  Where the acid itself is used this may be in the form of its salt with the amine.  The reaction may be carried out in the absence of oxygen at superatmospheric pressure, water being removed in the later stages by an inert gas stream, e.g. N2, or by application of a subatmospheric pressure.  Where the acid ester is used the reaction may be in 2 stages.  In the first stage the diamine and ester may be heated, optionally in a solvent, e.g. an alcohol or aromatic hydrocarbon to form a precondensate.  In the second stage the precondensate solution may be heated to distil off the solvent and complete the polymerization.  Heating in this stage may be above 200 DEG  C. and under an inert atmosphere of subatmospheric pressure.  Where the acid chloride is used the reaction may be carried out at a water/non-aqueous solvent interface, the diamine being dissolved in the former and the acid halide in the latter.  Non-aqueous solvents specified are CCl4 and toluene.  The reaction mixture may include a lactam, e.g. caprolactam, a chain terminator, e.g. a monocarboxylic acid or monoamine or an amide forming derivative of either, a thermal stabilizer, photostabilizer, optical brightener, filler and/or lubricant.  The products may be used to make injection mouldings, sheets, rods, bristles, filaments and threads.
