Title: Ozone producer for dust suction apparatus
IPC: A47L7/04
Filed: 1927-06-10
Abstract: 272,535. Inventia Patent Verwertungs, Ges. June 10, 1926, [Convention date]. Gases, treating electrically.-In dust-suction apparatus employing a d.c. motor M and wherein the air is treated electrically for the production of ozone, the alternating current for the fatter process is itaken directly from the motor commutator K. Commutator segments a, b of opposite polarity are connected to a transformer T functioning as a condenser, the secondary surrounding the primary and the air being passed between them. In one such arrangement, Fig. 5, the transformer is mechanically coupled to the motor shaft, the leads from segments a, b passing through the shaft. The transformer is arranged in the discharge aperture of the apparatus. The Specification as open to inspection under Sect. 91 (3) (a) describes a modification shown in Fig. 3 (Cancelled) having a stationary transformer T and condenser C, the transformer being connected to the segments a, b through slip-rings A, B. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to means both for holding in contact and for throwing-off co-operating rollers, cylinders and the like
IPC: B41F13/30
Filed: 1948-06-09
Abstract: 654,594. Printing &c. machines. TIMSONS, Ltd., TIMSON, E. A., and MILES, G. R. H. June 9, 1948, No. 15574. [Class 100 (ii)] In a printing or other machine a horizontallydisposed vertically-movable cylinder (e.g. an impression cylinder) is associated with a loaded lever system adapted normally to pull it downwardly into contact with another cylinder (e.g. a printing-cylinder) disposed beneath it at a relatively fixed location, means being provided, operable by an attendant, to shift the effective fulcrum point in the lever system whereby the load is applied through the system to throw the movable cylinder off the relatively fixed cylinder. In the printing- machine shown, the gravure cylinder 1 is mounted in fixed bearings, and the impression cylinder 4 and a backing roller 5 are mounted in two end-slides 3 which are vertically movable. The ball-bearings of the cylinder 4 have limited vertical movement in the slides, whereby, when the latter are lifted, the cylinder 4 and roller 5 can separate. Each slide 3 has adjustably attached thereto a bar 9 pivoted to links 11 which are connected to one lever 12, pivoted at 13, of a compound lever system 12, 14, 15 operating about a fixed pivot 16. The larger arm 15b of the lever 15 is urged upwardly about the pivot 16 by weights 21 suspended by a cord passing over around a fixed pulley 20, and a pulley 17 on the arm 15b, and secured to a fixed point 19, whereby the slide 3 carrying the cylinder 4 is pulled downwardly. The pivot 13 comprises a cross-shaft having eccentrics 22 thereon mounted in bearings 23 which can be rotated by either or both of two hand levers 24 by the attendant to raise the pivot-shaft 13 and hence the rear ends of the levers 12. During the initial movement of the lever 24, fixed stops 26 form temporary fulcrums for the levers 12, and the weights 21 then serve to push up, instead of pull down, the links 11, and consequently the slides 3, carrying the impression cylinder 4, are raised. Stops 25 limit the movements of the hand levers 24. The bars 9 have nuts 27 thereon engaging vertically-disposed screws 28 on the slides 3, these screws being interconnected, through bevel-gearing 29, 30, by means of a cross-shaft 31 adapted to be rotated by a hand wheel 32, whereby vertical adjustment of the slides 3 is effected when a larger or smaller diameter printing cylinder 1 is to be used.

Title: A method of and apparatus for generating high frequency vibrations by mechanical means
IPC: B06B1/10
Filed: 1942-11-05
Abstract: 581,809. Vibratory mechanism. CARTER, M., and CAMPBELL, A., (trading as UNIVERSAL VALVE & CHEMICAL ACCESSORIES CO.). Nov. 5, 1942, No. 15652. [Class 80 (iv)] High frequency vibrations are produced by a rotating shaft which causes a weight in the form of a ring to revolve and roll round a track of smaller diameter than the bore of the ring, the track being fixed to or forming part of the structure to be vibrated. The part A, Fig. 1, to be vibrated is suspended by two parallel and equal links D journalled on fixed centres E, and is fixed to a boss c, Fig. 2, a reduced part C of which forms a track for the ring B which is activated by a roller g<1> on a pin g mounted in a disc G secured to a driving shaft F rotatably mounted in the boss c. The shaft may be rotated by a pulley H or by a flexible drive. In a modification, Fig. 5, two shafts F, F<1> are geared by wheels M, M' to rotate at equal speeds in opposite directions. The shafts are mounted in bearings N in a casing L and its cover O. The bearings are carried in cylindrical members c on which are formed the tracks C. The inner ends of the tracks are spaced apart to accommodate a square portion F<2> in which is mounted a driving block P with an oblong hole to allow of radial movement. These driving blocks may be segments of circles, the curved parts engaging the bores of rings B which engage the tracks C. With the weights in correct phase, vibrations take place in a plane perpendicular to the paper. Alternatively, the two driving shafts may be mounted coaxially in stationary bearings and coupled together at their inner ends. Each shaft may have a disc with laterally projecting pins which engage the bore of a ring free to revolve and roll round a track fixed to the part to be vibrated. The devices may be force lubricated. According to the Provisional Specification, the ring may be replaced by a roller running round the inside of a track.

Title: Musical instrument rhythm programmer having provision for auto matic pattern variation
IPC: G10H1/40
Filed: 1974-04-09
Abstract: 1469838 Automatic rhythm programmer HAMMOND CORP 9 April 1974 [20 April 1973] 15696/74 Heading G5J An automatic rhythm programmer comprises a semi-conductor read-only memory 18 containing a separate set of signal tracks for each of a number of basic rhythm patterns, the required rhythm being selected by the appropriate pattern switch 27 and the tracks being energized in a predetermined sequence by pulses from the address decoder 13, each track activating certain of the voice generators 19, subject to override by signals from the track variation decoder 31, which enables a number of preprogrammed pattern variations to be introduced. The preferred embodiment incorporates sixteen basic rhythm patterns together with four pattern variations some or all of which are automatically introduced in a predetermined sequence on closing switch 36, the rate at which variations are introduced being controllable by the setting of switch 34. The beat or beats into which any particular variation is introduced depends, in general, on the part of the beat cycle in which switch 36 is closed. The operator can alternatively introduce any of the pattern variations manually by operation of pushbutton variation switches 41. The device is controlled by a regular sequence of square wave pulses from a master oscillator 10 whose tempo can be varied by a variable resistor (58, Fig. 4, not shown), the oscillator supplying pulses to the counter 11. The counter 11 in turn supplies pulses to the address decoder 13, and also to the track variation decoder 31 both directly and via the measure select switch 34, on-off switch 36 and variation counter 38, further details of these units being given in Fig. 4 (not shown). The read-only memory 18, address decoder 13 and track decoder 31 and their interconnections are preferably incorporated into a single integrated chip 14, using MOSFET transistors. Further details of a preferred circuit for the set of tracks corresponding to the dixieland rhythm and the resulting rhythmic patterns for the four proposed pattern variations are given in Figs. 3 and 5 (not shown). The voice generators 19 produce untuned percussion sounds and chords.

Component (3) is preferably the reaction product of ammonia or a primary amine with a mixture of halosilanes of the general formulae RSiHal3 and R2SiHal2.  The reaction is conducte at a temperature below 0 DEG  C., in the absence of water and in the presence of an inert organic solvent, e.g. methylene dichloride, and results in polymerization.  Halosilanes listed are mixtures of methyl trichlorosilane and dimethyldichlorosilane or phenyltrichlorosilane and diphenylidchlorosilane.ALSO:A heat-curable adhesive composition is used to coat metallic foil such as aluminium, stainless steel and copper.
