IPC: F15B11/12
Filed: 1955-06-22
Abstract: 791,008. Change-speed control. BROWN & SONS (HUDDERSFIELD), Ltd., D. Sept. 24, 1956 [June 22, 1955], No. 18010/55. Class 80 (2). A change-speed gear selector rod a, moved axially one way or the other to a gear engaged position and having an intermediate neutral position, is formed with an enlarged portion b and carries slidably a collar e, the various parts lying in different diameter cylinders c, f, g to which hydraulic or pneumatic pressure fluid is supplied through conduits h, j, k. The end area of the collar e subjected to pressure in the bore f is greater than the end area of the enlargement b subjected to pressure in the bore c. When pressure fluid is applied simultaneously through the conduits j, h to the bores f, c, the collar e is moved to its extreme right-hand position in the Figure and simultaneously the rod a and enlargement b are moved leftwards until the enlargement engages the collar. Thus a positively located intermediate neutral position of the selector rod a is obtained. Leftwards or rightwards movement of the selector rod to establish a selected ratio is obtained by admitting pressure fluid through one only of the conduits h, k to the bores c, g. One or more selector rods according to the invention may be applied to a change-speed gear having the selection and establishment of the different ratios controlled by a gear shift lever arranged to make an are or a complete circle of step-by-step movements. In a change-speed gear having more than one selector rod, suitable interlocking means are provided to prevent two gear ratios being simultaneously engaged.

IPC: B65B11/32
Filed: 1949-07-08
Abstract: 666,013. Wrapping-machines. HOHL, G. I., WEISE, F. H., RIST, G. A., and RIST, J. M. July 8, 1949. 18138/49. Class 94(i). A wrapping-machine includes a continuously rotated wrapping wheel provided with a multiplicity of circumferentially spaced pockets in its periphery together with an article delivery shcot and means to supply a wrapper across a wrapping wheel pocket disposed for reception of the article to be wrapped. Articles C to be wrapped are fed by a conveyer belt 33 over a delivery wheel 30 into a shoot 35 from which they drop singly to oscillating transfer means 37 which carries each article to a circumferential pocket 23 of a continuously rotated wrapping wheel 21, formed of two spaced wheel members 22 and thrusts the article, together with a wrapper cut from a strip W fed into the path of the article, into the pocket. The transfer means 37 is oscillated by a rotary cam 39 and has a head portion 49 on which is integrally formed an impeller member 50. Slidably mounted on said head 49 below the impeller 50 is a platform plate 54 whose bifurcated rear end engages longitudinal side grooves 53 in the head and whose front end is adapted to support the article C to be carried between side lugs 56 thereon, the impeller member 50, and spring-pressed gripper jaws 60 pivoted on said platform plate, Fig. 2. As the transfer means approaches the pocket 23 in the wrapping wheel the supporting plate 54 is halted by the contact of lugs 66 thereon with stops 67, the impeller member 50 however continues to move forward with the transfer means 37 and cam faces 65 on the jaws 60 contact the moving head 49 to open the jaws and allow the impeller member to push the article, and the wrapper W which has been pressed thereagainst by a yieldable member 72, into the pocket 23 where it is held by a spring-pressed jaw 27, Fig. 5. The trailing longitudinal flap f is then folded down on the face of the article by a folding blade 76, Fig. 1, carried by a camoperated pivoted arm 77, then, consequent upon the rotation of the wrapping wheel the forward longitudinal flap f<SP>1</SP> is engaged by a folding member 81, which folds it down on to the folded flap f. The trailing side flaps are then tucked inwards by tucker fingers 83 carried by rotating arms 82, Figs. 1, 9, and the extending trailing portions of the side flaps then folded against the ends of the article by folding fingers 84, also carried by the arms 82. The leading sides of the wrapper ends are then folded across on to the end faces of the article by their engagement with folding plates 85 and the outwardly projecting parts of the thus folded side flaps folded against the outer face of the article by a circumferential plow member 88, to be sealed by contact with a heated sealing iron 91. By this time the wrapped article has been carried to a position adjacent a discharge channel 96 into which it is ejected by a cam oscillated member 94 extending between the wrapping wheel members 22.

Title: Improvements in methods for preserving materials subject to putrefaction or decay and apparatus therefor
IPC: A23L3/32
Filed: 1919-07-21
Abstract: 139,100. Pape, R. July 21, 1919. Drawings to Specification. Preserving food.-To preserve foods &c., they are stored in chambers in which the ordinary electric potential gradient of the air is neutralized; it is stated that the development of bacteria &c. is thus prevented. The chamber employed is made of metal and is insulated from the earth. Ionization of the air within the chamber is prevented by passing through it a current of air which has been passed over a moistened surface or a metallic conductor. The chamber mav be double-walled, and the inlet ports for air in the two walls so arranged as to prevent the entrance of light and consequent ionization. Passing the air over a moistened surface also serves to increase its electric resistance and thus reduce electric currents in the chamber, but the amount of moisture in the air must be below saturation. A potential gradient in opposition to the normal gradient of the air may also be imposed on the chamber by a dynamo or the like, and may be regulated by clock-work or otherwise in accordance with the known diurnal variations of the atmospheric potential gradient.

Title: Adjustable compensating and centralizing chuck
Inventor: HOHWART GEORGE
IPC: B23B31/18
Filed: 1966-04-26
Abstract: 1,112,204. ChUcks. N. A. WOODWORTH CO. 26 April, 1966, No. 18286/66. Heading B3B. A chuck comprises a number of pivotally mounted arms each having a gripping jaw 21 movable radially relatively to a central axis, an actuator 23 movable along the axis and means operatively connecting the actuator and the arms comprising a spider 47 in the form of an annular member carried by the actuator for axial movement therewith, means 99, 103 for selectively allowing or preventing relative radial movement between the spider and actuator, and the spider being interconnected with the arms whereby axial movement of the spider causes pivotal arm movement. The surface 43 of the actuator is formed with the ribs 99 engaging the grooves 103 in the spider. In a first angular position of the actuator and spider, Fig. 1, each groove 103 in the spider is located intermediate the jaws 83. The extent of radial movement of the spider 47 relative to the actuator is determined by the relative diameters of the actuator at the rib 99 and the spider at the groove 103 so that a jaw which has contacted an irregular-shaped workpiece remains stationary and those which are not in contact are allowed to move a greater radial distance towards the chuck centre. In the second angular position, Fig. 2, each groove 103 is radially aligned with one of the jaws and actuator ribs and inner surfaces 101 of the spider are in contact. The rocker arms and jaws 21 thus move equal distances towards the chuck centre to grip and centre the work.

Title: Improvements in catalytic production of esters
IPC: C07C45/00
Filed: 1929-06-14
Abstract: 313,575. Du Pont de Nemours & Co., E. I., (Assignees of Lazier, W. A.). June 14. 1928, [Convention date]. Esters; alcohols; aldehydes: hydrocarbons.- Esters and some bye products are produced by passing a primary alcohol under pressure or not at 375-435‹ C. over a catalyst consisting of a difficultly reducible dehydrogenating oxide, chromite, or chromate such as an oxide of zinc, manganese, magnesium, or cerium, with or without a more acidic oxide such as an oxide of vanadium, chromium, tungsten, molybdenum or uranium as a promoter, or a mixture of an ordinarily reducible metallic oxide such as an oxide of copper, cadmium, lead and tin and a difficultly reducible oxide, in such a ratio to each other that the metals are maintained substantially in oxide form despite the presence of reducing gases. In examples, (1) butyl alcohol is passed over manganese oxide at 400‹ C., giving equal amounts of butyraldehyde and 'butyl butyrate; (2) methyl alcohol is passed over a mixture of magnesium oxide, cadmium oxide and chromium oxide at 350‹ C. giving formaldehyde and methyl formate; (3) ethyl alcohol is passed under pressure over a heated contact mass prepared by reducing basic zinc ammonium chromate with hydrogen. giving acetaldehyde and ethyl acetate and small yields of normal butanol, crotonyl alcohol, hexyl alcohol, esters of these alcohols and higher boiling products; copper chromite and manganese chromite, or easily reducible oxides such as oxides of cadmium, copper, tin, lead and bismuth when combined with chromium oxide, may also be used; the activity of zinc chromite is increased by adding thereto the chromite or chromate of a reducible oxide, e.g., the catalyst may consist of zinc chromite with the chromates or chromites of cadmium, copper, tin, lead or bismuth; mixed chromite catalysts are best prepared by precipitating the mixed double ammonium chromates of the metals from solutions of the salts with ammonium chromate and igniting the precipitate; (4) basic zinc ammonium chromate, obtained by mixing solutions of zinc sulphate and ammonium chromate and precipitating with ammonia, is heated to about 400‹ C. with formation of a mixture of zinc chromite and zinc oxide; ethanol is passed over the catalyst with formation of ethyl acetate and small amounts of acetaldehyde, ethylene. crotonyl alcohol, higher alcohols, and esters; (5) an oxide mixture prepared by treating stannous chloride with a solution of ammonia and ammonium chromate is used as in example 4; (6) zinc copper chromite, prepared by co-precipitating the basic double ammonium chromates of copper and zinc and igniting the mixed salt, is used as in example 4; (7) a solution of ammonium chromate and ammonia is added to a solution of zinc nitrate and cadmium nitrate and the precipitate is heated and used as in example 4. Specifications 272.555 and 301,806 are referred to. Reference has been directed by the Comptroller to Specification 282,448.

Title: Phase shift tremulant system
IPC: G10H1/043
Filed: 1973-04-17
Abstract: 1417254 Electrophonic musical instrument WARWICK ELECTRONICS Inc 17 April 1973 [17 April 1972] 18368/73 Heading G5J To produce tremulant effect in an electronic organ having separate left and right speaker channels 66, 72, phase shift is introduced into each channel at 6À7 Hz, the absolute and relative phase swings between channels depending on the organ voice in use. Sixty square waves, covering each semitone over five octaves, are supplied, 20, from twelve master sources by frequency division, to keying switches 24, 26, 28 on solo, accompaniment and pedal keyboards. Voicing circuits 34 on the solo board give choice of tibia, violin or complex voices; these and the other two keyboard voiced outputs 36, 38 are treated separately. Pedal output always feeds to a non- tremulant amplifier 62 and thence equally to the speaker channels; accompaniment and solo tibia and complex do likewise if their tremulant switches 60 are off; violin if its switch 60 is off feeds the left channel only. When tremulant is required solo complex voice feeds left and right channels via separate phase-shifters 80, 78 with phase inversion 100 in one channel; accompaniment omits inversion, solo tibia also omits inversion and enters phase shifters at an earlier stage to increase shift, and violin feeds only the phase shifter on the left channel. Each phase shifter comprises two units in cascade, entered by tibia voice signal before the first unit, by other voices before the second unit. Each unit comprises two phase-shifting stages, each followed by an impedance reducing transistor. Each stage output is taken from the junction of an inductor and light sensitive resistor fed in series between direct and inverted signal potentials on the emitter and collector of a basefed transistor. The inductors are modified by capacitors to reverse the direction of phase shift -below a critical frequency, being 84, 42, 190, 84 Hz in successive stages, so tending to equalize the percentage frequency swing on low and high notes, summed over all stages used. Maximum phase shift is approximately 177¢ degrees per stage or 710 degrees in the complete phase shifter; the shift depends on the intensity of light from a lamp lighting all four resistors. Right and left channel phase shifters are identical and both lamps are driven, 92, 96, from the same 6À7 Hz oscillator 90 supplying zero based square wave; however the right lamp waveform is modified to be double peaked 94. All these arrangements are stated to be found empirically to improve the musical tremulant effect.

Abstract: 755,011. Aerials. STANDARD TELEPHONES & CABLES, Ltd. July 25, 1952 [Aug. 3, 1951], No. 18390/51. Class 40 (7). Directive aerial systems required to produce narrow beams for radio link or radar purposes include iris systems consisting of energy absorbing means cutting off and absorbing radiation from the primary element directed in undesired directions. The primary element may be situated at the focal point of a concave mirror 3 and energy from it directed vertically through the apertures in three iris units 5, 6 and 7 before being directed by reflector 4 in the required direction. The lowest iris 5 is preferably of hemispherical shape 5a but may be conical 5b; it is placed to cut off all radiation except that passing through aperture 8 in a substantially vertical direction. Dish-shaped iris 6 and substantially flat iris 7 are added to further improve the beam. The energy absorbing surfaces of the iris units are mounted on a rigid backing of metal or wood 11. The surface itself consists of a honeycomb structure of dissipating waveguides 15. The guides are an odd multiple of a quarter of the working wavelength long and formed of, or coated with, high-loss material. The ends of the tubes are sealed by layers 16 and 17 of the same material and the surface not supported by the backing 11 given a layer of varnish 13. The aerial system may be used for transmission or reception. If it is to be used for reception the outer (backing) surface of the iris units should be metal, so as to act as a reflector, except immediately surrounding the aperture where energy absorbing material is preferred to prevent eddy currents.
