Title: Improvements in or relating to the art of producing baked cereal products
IPC: A21D2/38
Filed: 1936-02-14
Abstract: In making bread, biscuits, cakes, and like baked cereal products, finely divided barley, wheat, maize, or other malt particles of such size that they can readily be distinguished from the remainder of the product by the naked eye, are mixed with the other dough ingredients and the dough is allowed to ferment and rise and baked.  The malt particles may be such as will all pass through a 6 mesh, but the greater part will not pass through a 25 mesh screen.  Malted milk may also be added, e.g. about 2 parts by weight of malted milk and 15 parts of the malt particles may be employed to 100 parts of flour. Where malted milk is used, inorganic salts such as sodium chloride, sodium bicarbonate and calcium acid phosphate may be included to give improved texture, flavour and keeping qualities and increased volume in the bread &c.  Whole, partially skimmed or skimmed milk in dried form may also be added.  Examples of proportions which may be used are given in the Specification.  The loaf or other unit of dough may be lightly covered with malt particles before baking.  The Specification as open to inspection under Sect. 91 comprises also the use of malt generally with the malted milk.  This subject-matter does not appear in the Specification as accepted.

Title: Arrangement for electrically heating air and other gases to high temperatures
IPC: F24H3/04
Filed: 1938-02-14
Abstract: 499,074. Heating air &c. electrically. SCHOTTKY, W. Feb. 14, 1938, No. 4522. Convention date, March 2, 1937. [Class 39 (iii)] Air and other gases are heated to high temperatures by passage under pressure through a plurality of directly adjacent parallel passages with cold inlet portions. The parallel passages in the ceramic body in Fig. 1, contain hairpin form heating wires or coils 2 extending over part of their length. The wire is continuous and may extend completely through the end passages which may be of smaller section. The outer surface of the heated portion may be silvered. A temperature of 700‹ C. and a passage area of 4 mm<2>. are referred to. In Fig. 12 the passages are formed by parallel sinuous bands 1, 2, 3, forming heating resistances. The inlet portions of the bands are slotted at intervals to break their continuity, or are considerably thinner than the remaining portions to increase considerably their resistance.

Title: Improvements in and relating to frequency modulation circuits
IPC: H03G11/06
Filed: 1950-02-22
Abstract: 669,717. Frequency modulation. BRITISH THOMSON-HOUSTON CO., Ltd. Feb. 22, 1950 [March 1, 1949], No. 4566/50. Class 40 (v). A reflex amplifying and limiting circuit for reducing noise in an F.M. receiver comprises an I.F. amplifier valve 6 with serially connected anode circuits 16, 18 tuned to the fundamental and a harmonic, e.g. second harmonic respectively of the input centre frequency, circuit 16 being connected to a frequency multiplier valve 37 and anode circuit 41 tuned to the harmonic coupled to a similarly tuned circuit 7 in the input circuit of the valve 6. The output at the harmonic frequency after amplification is derived from tuned circuit 18 by a discriminator 25, 26 tuned to the harmonic. The valves 37, 6 are self-biased by grid flow to resistor-capacitor networks 39, 40 and 9, 10 in their input circuits and both limit the R.F. harmonic input voltages between zero and cutoff voltage of the control grids. Valve 37 further acts as a saturation limiter due to a high value of resistor 42. Delayed AVC voltage is derived across circuit 9, 10. Quiet operation is further achieved due to the output of multiplier valve 37 being negligibly low for small inputs. Specifications 618,462 and 627,238 are acknowledged.

A turret lathe comprises a tool-turret mounted on a shaft parallel to the axis of the headstock and a follower arm extending radially from the turret shaft having a feeler for following a template, the turret and follower arm being latched together with the desired tool in the operative position and means for moving the turret shaft along its axis so that the feeler follows the template to give the required movement to the turret during turning. A handoperated embodiment of the invention comprises a tool-turret 2, Figs. 1 and 2, secured to a shaft 1 which is rotatable for indexing and may be moved axially for longitudinal feed by a pinion 6 and teeth 7. Indexing is effected by fully retracting the turret so that one of the pins 18 strikes a lever 19. A lever 8 is rotatablymounted between collars 9, 10, on the shaft 1 and may be locked to collar 10 by a pivoted handle 12 thereon having a pin 13 which engages one of a series of holes, corresponding with the number of turret stations, provided in the collar 10. The lower end of the lever 8 is adapted to bear either against a straight-edge 16 for parallel turning, or against one of the template edges 17 of a turret template-holder which can be indexed as required. An automatic embodiment of the invention comprises a turret 31, Fig. 3, secured to a shaft 30 movable longitudinally for the traverse by an hydraulic piston-and-cylinder arrangement at the headstock-end of the machine. The righthand end of the shaft is provided with adjustable stop-members 65 which limit the longitudinal and transverse feeds by abutting stopsurfaces 66, 67, respectively. Two arms 39, 40, Fig. 4, are provided on the shaft 30 and can be automatically clamped thereto, these control the copying and indexing movements. The first arm supports a slide 57 which carries an hydraulic feeler device 58 for copying. The second arm 40 is connected to slide 57 by a pin-and-slot device and is clamped to shaft 30 to transmit the copying movement as the feeler 58 passes over a template 61 of an automatically indexible template-holder 68. For straight turning and drilling the arm 39 is locked to shaft 30 through an hydraulically-operated pawl which determines the indexed positions of shaft 30. The lower end of the arm is then guided along a straight-edge 56 against which it is held by an hydraulic plunger 54. Cycle control of the machine is effected by a punched pattern card, which is moved along in steps to change the operations. Contactbrushes make contact through holes in the card with a conductor rail to close parts of electric circuits. The latter are connected to solenoidoperated hydraulic valves which operate the various parts of the machine. :

Filed: 1929-02-14
Abstract: 306,093. Barrett Co., (Assignees of Miller, S. P.). Feb. 15, 1928, [Convention date]. Scrubbing and washing processes.-Pitch and oils are obtained at coal-distillation plants by collecting the gases from the uptake pipes 6 of a number of ovens or retorts and passing them at high temperature through a common collecting main 7 over the surface of a stream of tar continuously circulated from a storage tank 9. The hot gases partially distil the tar. and the vapours produced are carried by the gases through a scrubber 16, where suspended pitch particles are removed by spraying with pitch, or tar to condensers 25 in which clean oils are recovered. The gases are preferably scrubbed with hot pitch of the same composition as the pitch particles suspended therein and part of the pitch is simultaneously distilled and carried over into the condensers where it is condensed with the oils, the residue of the scrubbing medium being circulated with the tar in the collector main. By varying the temperature of the gases and the composition of the circulating tar and scrubbing medium pitches of different melting points are obtained. Specifications 284,703 and 289,023 are referred to.

Title: Improvements in or relating to the production of gears having crowned teeth
IPC: B21H5/02
Filed: 1969-01-29
Abstract: 1,225,957. Rolling gear teeth. F. F. ERDELYI. 29 Jan., 1969 [31 Jan., 1968], No. 5025/69. Heading B3M. The teeth of a gear-wheel are provided with a crowned profile by rolling the gear-wheel in contact with a toothed roll, a relative tumbling motion being provided between the gear-wheel and tool. In one embodiment, Fig. 2, a gearwheel 1 to be crowned is pressed by an hydraulically-operated plunger 11 against a toothed master gear 8 and is rolled by surrounding rolls 2. The gear 8 is driven and serves to drive the meshing rolls 2, the gear-wheel 1 being moved axially relative to the rolls. The rolls 2 are carried on eccentric shafts 17 and can be radially adjusted by toothed sectors 26 coupled to the shafts. Rotation of a ring gear 25 leads to rotation of the sectors and of the shafts 17, with consequent adjustment of the rolls. The plunger 11 includes a support rod 15 whose axis performs a wobbling motion by following the surface of the cone. The gear-wheel 1 therefore performs a wobbling motion relative to the tools. The tools themselves can be arranged to wobble about their axis of rotation using individual drives for them. By wobbling the plunger and gear-wheel in a single plane, rather than in a conical path, either radial or axial crowning can be produced. An alternative mounting for a gear-wheel 1, Fig. 3a, consists of eccentrics 53, 53a, whose speed of rotation is different from that of the gear wheel due to its contact with the tools 2. Control of the form of crowning is possible by adjustment of the wobbling motion both of the gear-wheel and of the tools 2 about a centre 7. The rolling operation may form teeth completely on a gear-wheel blank, but it is preferred that the teeth are performed by milling, planing or grinding and are subsequently crowned by cold-rolling.

Abstract: 251,050. Sayers, W. B., and Baxter, P. Feb. 24, 1925. Coils and conductors; cores; com m u t a t o r s ; insulation; mounting rotors; windings.-An armature consists of a core and a laminated tubular outer unit formed by the conductors with interleaved insulating and magnetic material disposed in involute curves, the conductors being extended to form a commutator and being provided with projections which engage the notched core for driving. The whole is secured on the core by a tapered split bush. The core is made of corrugated notched discs m, Fig. 5, or spirally laid corrugated strip, with polygonal holes m<1> for mounting them between end plates n on gib-ended plates b<1>. Fig. 2, within which are forced split polygonal driving-bushes as shown in Fig. 6. The tubular conductor system consists of copper laminae e, Fig. 3, to each of which is secured an iron lamina f with bent-over edges f<1>, f<2>. The conductors and iron are respectively bent to a single and double involute form, as shown, to give an interlocking and are separated by insulating material g. The conductors are connected by members h to form a closed winding, of which a single turn is shown in Fig. 7. The extensions e' of the conductors form the commutator and the laminae e, f and conductors h are held together by bindings l and cement or varnish. Mica or other insulation is inserted between the core laminae and the tubular conductor unit. For high-voltage windings, the iron laminae are provided with a third reversely turned involute part, beyond that which contains the conductors h, and the spaces between these parts contain coiled wire armature conductors and their insulation. In place of tightening the core against the inner periphery of the conductor system by means of the split coned bush, the core may be compressed axially so that the corrugations are flattened somewhat and the external diameter of the core is enlarged. The Provisional Specification states that the commutator may be formed by nested curved metal strips, insulated from each other and connected to the conductors, instead of by the ends of the conductors; also that the drive may be transmitted by raised segments on the core engaging corresponding surfaces on the inner periphery of the tubular conductor system, and that two systems of conductors may be employed, one formed of laminae to give low voltage and the other of wire to give high voltage.
