Filed: 1940-02-15
Abstract: 535,985. Grinding MICROMATIC HONE CORPORATION. Feb. 15, 1940, No. 2928. Convention date, Feb. 23, 1939. [Class 60] [Also in Group XXII] Hollow cylinders such as valve sleeves and cylinder liners are made from cast, forged, die pressed, extruded or similarly formed blanks. In the case of a flanged cylinder liner the blanks are centrifugally cast, and then heattreated to harden them. They are then gripped by the unmachined exterior and the bore is rough honed. In the next stage the blank is mounted on expanding mandrels carried by a driven headstock and by a tailstock mounted on a bed adjustable on ways 63 by a hand wheel 64. Grinding is effected by three wheels mounted on a table 32 sliding on ways for axial feed at 35. The wheel 58 is shouldered and grinds the exterior surface and part of the flange, one wheel 48 grinds the unflanged end whilst the other wheel 48 finishes the outer face of the flange. The blanks are next gripped by the finish ground exterior for finish honing of the bore.

Title: Improvements in or relating to frequency modulation receivers
Inventor: O'DELL ALBERT GEORGE
IPC: H03G11/06
Filed: 1953-02-04
Abstract: 742,597. Frequency modulation. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Feb. 3, 1954 [Feb. 4, 1953], No. 3113/53. Drawings to Specification. Class 40 (5). In a F.M. receiver the limiter is preceded by an I.F. amplifier with anode circuit tuned above the frequency band of the signal so that the working point lies on the sloping side of the lower frequency end of the tuned circuit characteristic, and, since the input capacity of the limiter decreases with increase of signal strength, the anode circuit is further mistuned with increase of signal amplitude. The ability of the limiter to deal with amplitude modulation is thereby increased. The tuning capacity of the anode circuit of the amplifier must be small to provide the required degree of control, or the input capacity of the limiter is relatively increased by a capacitor between its anode and control grid. The limiter anode circuit may be off-tuned and feed a diode detector.

[Class 7 (iii).] The injector described in the parent Specification is modified so that, instead of fuel being supplied through a bore in the member 2, it is fed to a space between the members 1, 2 ; the surfaces 20, 21 serve to seal this space, which may be sufficiently narrow to constitute a filter. As shown in Fig. 1, a cap 5 holds the fuel feed pipe 7 against the member 2. In the modified construction shown in Fig. 3, the fuel feed pipe 7 is secured to a branch 24 of the body 1 by a cap 25, and the fuel traverses passages 26, 27 to the top of the annular space 28. In a further construction, the member 2 completely fills the body 1 above the level of the fuel admission orifice to the annular space ; thus spaces not traversed by the fuel are avoided.

Title: Improvements in coin-testing apparatus
IPC: G07D5/04
Filed: 1930-02-03
Abstract: 347,318. Testing coins; coin-freed apparatus. IMPERIAL TOBACCO CO. (OF GREAT BRITAIN & IRELAND), Ltd., East Street, Bedminster, Bristol, and HASTED, H. C., 46, Buchanan Gardens, Willesden, London. Feb. 3, 1930, No. 3562. [Classes 27 and 116.] In a' coin-tester to distinguish between coins having embossed and smooth sides respectively the' coin obstructs an air passage and the magnitude of the obstructing effect so produced on the flow of the air controls means for discriminating between such coins. A coin inserted in a shoot 7 falls on to a counterweighted shovel-like member 6 pivoted at 5 and carrying a cylinder 8 which contains a piston 11. The coin covers an open end 9 of the cylinder and if embossed does not form an airtight joint so that the piston 11, which tends to fall as the member, 6 tilts, drops freely. It then actuates an arm 16 of a counterweighted lever 12 passing between balls 17, 18, mounted on the piston, whereby a claw 19 on the said arm engages the coin to prevent it falling off the shovel 6. When the piston strikes an abutment 42 on a pivoted member 20 due to the tilting of the shovel 6, it moves back, along the cylinder, 8 so that the claw 19 is withdrawn from the coin which then drops into a shoot 35. A smooth, coin forms a substantially airtight joint so that the fall of . the piston 11 is retarded. The claw 19 does not engage the coin and when the shovel 6 is tilted the coin falls into a space 40. A. heavy embossed .coin tilts the shovel 6 with such a speed that the coin when released falls into a space 41. The claw 19 preferably engages the flange of the coin so that embossed coins without a flange are rejected. Light coins are removed from the shovel by rotating the member 20 so that a sector 22 thereon engages with teeth 23 on the pivot 5 of the shovel. The latter is tilted until the piston 11 engages an abutment 45 on the member 20 when the coin is prematurely released and falls into the space 40. The member 20 may be rotated by prongs 24, 25, or if the device is applied to a coin-freed delivery machine, by the opening movement of the delivery mechanism. After slight tilting of the shovel 6 a tipping platform 26, pivoted at 27, forms a continuation of the shoot 7 so as to deflect any coins inserted to a return shoot. An arm 43 on the lever 12 prevents such coins being intercepted by the claw 19. A canvas filter over the top of the cylinder 8 prevents dust reaching the inside thereof.

Abstract: 962,592. Sharpening machine cutters in situ. IMPERIAL CHEMICAL INDUSTRIES Ltd. Jan. 16, 1963 [Jan. 31, 1962], No. 3695/62. Heading B3D. [Also in Division D1] In fibre-stapling apparatus, continuously moving filamentary yarn carried round the periphery of a wheel 5 is severed by the cutting edge or edges of a positively rotated circular knife 3 (or a series thereof) periodically and/or successively passing through slots 4. Each blade edge is engaged on opposite sides by two abrasive stones 6 and 7, mounted on separate or common spindles at an angle to the axis of the blade and positively driven, or rotated by engagement with the rotating blade, or stationary, so that continuous sharpening occurs. Blades and stones are mounted on a turn-table 1 rotating synchronously with wheel 5 to effect the cutting. Each blade 3 is tilted at an angle to the turn-table which is itself tilted relative to wheel 5 so that the point of contact of the blade with the yarn moves, at a similar velocity, in the direction of the yarn during passage of the blade therethrough. The relative speeds of rotation of turn-table 1 and blades 3 (e.g. 500: 101) may be such as to equalize wear over the cutting edges and ensure that each blade is sharpened between successive cuts. Specifications 682,473 and 720,233 are referred to.

Title: An improved method of, and apparatus for, recording sound
IPC: G11B7/00
Filed: 1934-02-05
Abstract: 432,811. Recording sound. RADIO CORPORATION OF AMERICA, 30, Rockefeller Plaza, New York, U.S.A. Feb. 5, 1934, No. 3739. Convention date, Feb. 24, 1933. [Class 40 (ii)] Relates to soundrecording apparatus in which the sound waves impinge on a diaphragm which directly effects the recording. According to the invention, in usng such a device for producing a variable-width photographic record that gives a minimum of background noise on reproduction, the diaphragm is biassed by a pressure dependent on the volume of the sound being recorded. The invention is stated to be applicable also to recording by means of a phonograph stylus or the like. As shown, a diaphragm 20 in a sound-box 10 is connected bv a rod 22 to the vibratory support 23 of a light-reflector, which may be a lens mirror (not shown). Using an optical system of the ordinary kind, light is reflected from the mirror through a slit on to a photographic film. The back 25 of the soundbox has an aperture 26, covered by a resilient flap 27, and the rod 22 is surrounded by a rubber &c. washer 28 where it passes through the back 25, to prevent air leakage. When sounds of large amplitude vibrate the diaphragm, air escapes past the valve 27, producing a large biassing pressure on the diaphragm, since the rate at which air returns to the chamber behind the diaphragm is small. With sounds of relatively small amplitude, little air is ejected through the valve 27, and the bias pressure is low. Thus, the arrangement produces a record such as is shown in Fig. 2, the zero line of the oscillations being shifted in accordance with the amplitudes.
