Title: Improvements relating to the breaking of wheat, rice and like granular materials
IPC: B02C9/04
Filed: 1921-12-28
Abstract: 195,444. Chemical Engineering Co. (Manchester), Ltd., and Spensley, J. W. Dec. 28, 1921. Reduction processes.-Grain is reduced by treatment in a combination of break rolls or other ordinary milling-appliances, with highspeed centrifugal pin-disc mills. The grain may be subjected to lighter treatment in the earlier break-rolls, and the final tailings, consisting mainly of bran, are then treated in a pin disc mill to obtain a further vield of flour. Fewer sets of break-rolls may be employed. The earlier break-rolls, except the first, may be replaced by pin-disc mills which are run at a lower speed. The air blast produced by the disc mills may be utilized to perform a preliminary separation of the product. Specifications 2224/10 and 166,462, [both in Class 59, Grinding, crushing, &c.], are referred to.

Title: Improvements in an orchestral instrument
IPC: G10H1/18
Filed: 1931-12-16
Abstract: 390,574. Electrical musical instruments. LUEDTKE, H:, 21, Germania Garden, Templehof, Berlin. Dec. 16, 1931, No. 34883. Convention date, Dec. 16, 1930. [Class 88 (ii).] In an electrically operated organ or like musical instrument, the keys of a single keyboard are connected to a system of electromagnetic relays operating in such manner that sound producing devices of various characteristics such as the stops of an organ are associated in a predetermined manner with each note of a chord. For example, the highest note of a chord may sound with the character of one stop, the next lower with that of another stop and so on. In the relay system shown in Fig. 3 each key a, f, d is connected to a set of relays comprising coils S, O and armatures. On depression of the key a current flows through both coils of the lowest relay raising both armatures, so as to make contact between the points K, J and break contact between the points L, A and M, N. Connection for the note a<1> is thereby established in sound-producing system I and blocked in sound-producing systems II, III. If the key f is simultaneously depressed connection for the note f<1> is similarly established in system I, and also in system II, blocking action by the coil O<1> being prevented since its circuit is broken at L, A. Simultaneous depression of key d sounds the note d<1> in all three systems. Further coupling effects may be obtained by the provision of " blank switches " i which while' not releasing notes themselves have a blocking action on lower notes. Depression of the switch i shown allows the note f to be played in both systems I and II although no higher note is being played. The " blank switches " may be arranged in a separate row below the sound keys. The sound-producing system may comprise any combination of pipes, reeds, electrical oscillation generators, and apparatus for the reproduction, e.g. photo-electric reproduction, of separate sounds recorded on films, discs or magnetic bodies. The relays may control not only the sounding of separate devices of different timbre but the application to any one device of controls for volume and timbre and of tremulants and like sound-modifying appliances. The sound systems I, II, III on which the electromagnetic selector operates may each comprise a number of different sound-producing devices and their controls, the constitution of each system being variable by the player. A combination of such devices and controls may be " set by the player and " brought on " at a required moment by actuation of a single button. It may be similarly cancelled, and a second prepared combination brought on. Controls are set in fixed stages such as those of a swell box. Where a control is set at a given stage in a prepared combination this serves as a zero point which may be exceeded at will by the manipulation of free switches. Specification 370,475 is referred to.

Abstract: 835,336. Pneumatic springs. FIRESTONE TIRE & RUBBER CO. Nov. 12, 1957 [Dec. 7, 1956], No. 35203/57. Class 108(3) In the manufacture of an air spring a liner 23, Fig. 5, and plies 16, 17 are assembled on a drum 25, Fig. 3, which consists of portions 28, 26, 27. After this assembly, an end section 27 is drawn to the right to leave the ply ends projecting beyond a shoulder 30. The ends are now turned in and a bead ring 18 is set as shown in Fig. 5. A mandrel 31 is moved to the right and expanded, Fig. 7, by a grooved conical member 37 which forces apart fingers 35 of the mandrel. This action pushes the plies outwards as shown in Fig. 7. The plies are next pushed into the position shown in Fig. 8, by a ply turning sleeve 32 where they can be held for stitching by a roll 41. A keeper 45, Fig. 7, prevents ends 36 of fingers 35 from slipping out of a groove 43 in a plug 44. A resilient rubber ring 51 urges the fingers into closed position. A coil spring 53, Figs. 7, 10, bridges fingers 35 in the open position to prevent the formation of wrinkles in the plies. Fig. 11 shows an alternative construction of mandrel in which flanges 74 overlap when the mandrel is expanded. Specification 819,728 is referred to.

Title: Improvements in mechanism for regulating the speed of shafts
IPC: D01H1/24
Filed: 1953-12-18
Abstract: 728,035. Magnetic brakes. FISCHER, M., and STALDER, O. Dec. 18, 1953 [Dec. 23, 1952], No. 35343/53. Class 35. [Also in Group IX] The speed of shafts, in particular those of spinning machines which are rotated by means of a gaseous pressure agent, e.g. compressed air, is controlled by adjusting the air gap between a permanent magnet mounted in the said shaft and the adjustable poles of a stationary permanent magnet arranged outside but co-operating with the first permanent magnet. Fig. 1 shows such spindle 5 which is rotated by blades 13, 18 of an air turbine. A permanent magnet 21 rigidly mounted on the spindle 5 is arranged to rotate between the pole-shoes 23 of a stationary but adjustable permanent magnet. A shortcircuited winding 22 surrounds each of the pole-shoes 23. By altering the air gap between the rotating magnet 21 and the poles 23, the braking action in the spindle 5 is altered accordingly and so is its speed. The adjustment of this air gap is effected by controlling the position of the poles 23 by means of trapezoidalshaped control members 29 which are in turn actuated by guiding slide 30 best shown in Fig. 4. The members 29 when moved upwards in the direction of the arrow shown in Fig. 4 cause the pole-carrying plates 27 to move outwardly against springs 25 and thus produce the required adjustment of the air gap between the permanent magnet and the poles. The control members 29 may be wedge-shaped also, instead of a common straight contacting edge between the plates 27 and the control members 29 a cam could be used and positioned in either of the plates 27 or members 29. A single movement of the slide 30 is sufficient to alter the speeds of several shafts, e.g. in Fig. 4, two such shafts 5 have their speed adjusted by the slide 30.
