Title: Improvements in connection with motor driven vehicles
IPC: A63G25/00
Filed: 1927-11-14
Abstract: 306,061. Johnson, J. Y., (Lusse Bros., Inc.). Nov. 14, 1927. Addition to 225,601 and 306,059. Disconnectible gearing; de-clutching for steering; wheel-driving attachments; transmission gear of invariable ratio.-In a motor vehicle of the kind described in the parent Specifications in which a steering post is rotated about its longitudinal axis for steering and is rocked about an horizontal axis to control the driving gear, the latter comprising frictional driving elements each secured to a shaft eccentrically mounted in a rotatable member so that by rotating the members the frictional driving elements are brought into and out of engagement with the traction wheels, coupling members are provided which connect the motor shaft to the shafts of the frictional driving members and normally prevent the removal of the last-mentioned shafts from the removable members at least in one direction. The invention is shown applied to an amusement vehicle in which an electric motor driving the vehicle is supplied with power from two conductors, one comprising an electrically conductive floor over which the vehicle runs and the other an overhead metallic surface. The motor 91 drives two friction rollers 32 eccentrically mounted in sleeves 53 carried by bearings 54 so that by rotating the sleeves by means of arms 62 the rollers can be brought into and out of engagement with their respective traction or driving wheels 13. The arms 62 are rocked (1) together to start or stop the drive, when the steering post 105 is swung about a universal joint 107, and (2) separately, to assist in steering, when the post is turned about its axis to rotate the steering wheel 103. The motor shaft 92 carries a pinion 93 at each end gearing with an internally-toothed wheel 79 fixed on the shaft 37 of the friction roller. Since the motor shaft is coaxial with the sleeves 53 any rotation of the latter will not disturb the mesh of the gearing 93, 79. The gear wheel 79 is carried by a coupling member 78 formed in two parts bolted together and screwed on the end of the roller shaft 37, thereby preventing movement of the shaft in an axial direction through the sleeve 53. The friction roller is secured bv a ring 42 and screws 44 to a flange 41 shrunk on or otherwise fixed to the shaft 37. The roller shaft is carried in ball bearings 47, 48 spaced apart by sleeves 74, 75, and lubricant is retained by means of packing 68, 89. Apertures 34 are formed in the wheel 13 large enough to permit the friction roller to pass through. To withdraw the roller and its shaft the bolts 86 of the coupling 78 are. slackened and the shaft is unscrewed therefrom, a tool slot 90 being formed in the end of the shaft to facilitate this operation. When the shaft is unscrewed from the coupling it may be withdrawn together with the roller through the opening 34.

Abstract: 404,429. Pasteurizing liquids. MARSHALL, G. S. C., and CLAYTON, G. S., St. Anne's Works, St. Anne's Street, Limehouse, London. Oct. 31, 1932, No. 30616. [Class 49.] In a multi-container pasteurizer having a draw-off valve common to all the containers, the housing of the valve is adapted to contain or receive a distributer through which a sterilizing medium, e.g. steam, can be passed into the containers to sterilize them. As shown, the containers 10 are surrounded by a common hot water or steam jacket 12 and are arranged in semi-circular formation in respect to a vertical rotating shaft 11 actuated through reduction gear from the main drive 18. The containers are filled with the liquid to be treated from a pan 19 having a spout 20 and carried by the shaft 11 so that it discharges in turn into compartments in a fixed tray 21, each compartment communicating through a pipe 22 with the corresponding container 10. Each container 10 has an outlet communicating through a pipe 26 with an aperture in the housing 27 of the discharge valve 30. This valve has a passage 31 adapted to be related in turn to the outlets for discharging the contents into a receptacle, and is connected to the shaft 11 by a sleeve 34 which is slidable vertically on shaft 11 but has a slot 35, Fig. 3, in which a pin 36 on the shaft engages to prevent relative rotation. The sleeve 34 has square cut lugs 33 which engage with a slotted flange 32 on the valve. When sterilization of the containers is required, the sleeve 34 is raised and held in position by the pin 36 engaging in an offset part of slot 35. The valve 30 is then replaced by a distributer 37, Fig. 5, of corresponding shape and having passages 38, one for each container outlet. Steam is supplied through a flexible pipe 40 and a passage 39 to the passages 38 from which it passes to the containers ; the supply can be controlled by turning distributer 37. The passages 38 may be joined at their outer ends by a groove 38a ; only one passage 38 may be used together with a groove. In a further form, the valve housing 27 may include twin rotary valves, one for drawing off the liquid and the other for introducing the sterilizing medium. The containers may have agitators 23 which are actuated by their shafts being linked to a strap 24 which embraces an eccentric 25 rotatably mounted on shaft 11 and driven through a belt independently from the main drive 18.

Title: Apparatus for drawing parabolas and other mathematical curves
IPC: B43L11/02
Filed: 1924-12-20
Abstract: 247,343. Davey, F. W. Dec. 20, 1924. Flexible strips. - For drawing mathematical curves, a flexible strip is passed through guides A - - D<1> arranged on a lattice frame comprising pivoted links in which all the lengths a are equal and all the lengths b are equal. Then if the lengths l, m, n are adjusted so that for a particular adjustment of the lattice the guides lie on a curve of the form y=kx<n>, these guides will lie on a curve of the same general form for all adjustments of the lattice, the value of k depending, on the angle #. For example the apparatus may be proportioned to describe a series of parabolas or a series of rectangular hyperbolas. The guides are preferably in the form of slotted pins through which the strip is passed, the pins being bevelled to facilitate the smooth movement of a drawing pen &c. A scale may be provided, so graduated that the distance between the points D, D', measured on the scale gives the characteristic constant of the curve, e.g. the latus rectum of a parabola. By slightly varying the proportions of the lattice, curves may be drawn which approximate closely to certain curves not included under the formula y=kxn, e.g. the arc of a circle, a catenarv or a sine curve.

Title: Improvements in or relating to the production of artificial materials
IPC: C08L1/08
Filed: 1934-10-29
Abstract: Artificial filaments, foils, films, and like products coloured in dark shades are made by imparting the required shape to a solution comprising a cellulose ester or ether dissolved in a solvent medium and which contains a dyestuff of the Nigrosine or Induline type and effecting setting of the shaped solution.  Thus filaments may be formed by extruding the solutions into a coagulating medium whether gaseous or liquid, e.g. into an p  evaporative atmosphere.  Fast black shades and a variety of deep shades may be obtained by topping with suitable colours.  Since induline and nigrosine dyes have a corrosive action on metallic portions of the apparatus it is necessary to take special precautions, e.g. by using annealed or coated apparatus, when employing these dyes.  By subjecting the dyestuff to the action of an alkali in a solvent for both dyestuff and alkali their corrosive action on spinnerets, pumps, &c. which contain copper, zinc or iron alloys may be reduced or eliminated. Water-soluble dyes may be prepared by subjecting the treated dyestuffs to sulphonation.  The solutions may contain besides the dyestuff and the cellulose ester or ether, other ingredients, e.g. filling and effect materials, e.g. metal oxides, powdered metals, lamp-black or logwood pigment, fire retardants, e.g. b -chlornaphthalene and tricresyl phosphate, plasticizers, e.g. glycol and glycerol oleates and stearates, or lubricants, e.g. olive oil and mineral oil.  Other dyestuffs, e.g. m-nitraniline yellow or 2 : 4-dinitrodiphenylamine may also be added.

Abstract: 386,387. Electric induction furnaces. ALLM€NNA SVENSKA ELEKTRISKA AKTIEBOLAGET, Vasteras, Sweden. Nov. 10, 1931, No. 31144. Convention date, Aug. 29. [Class 39 (iii).] In a furnace without a closed ferro-magnetic circuit and having a winding divided into several sections part only of the sections are connected to the source of supply, the remaining part being merely inductively coupled with the first part. Each of the sections of the second part is connected to a condenser which covers its reactive power demand. So that the current load will be the same on each section the proportion of the sections, counted in active conductive area, connected to the supply is the same as the proportion of active power demand to the sum of the active and reactive power demand. If a plurality of coils are connected to the generator they are preferably fed from electrically separate windings. The furnace winding comprises coils 31 .. 36. The coil 36 is tubular and supplied with a cooling medium. It is provided with tappings and connected to a generator 4 in series with a capacity 5 which compensates for the selfinductance of the generator. A condenser may also be fitted in parallel with the coil 36. The coils 31 .. 35 are copper bands and are simply connected to condensers 61 . . 65 through switches 71 .. 75. The reactive power demand increases as melting proceeds and the switches 71 .. 75 are closed as required starting with the inner ones. The depth of the bands may decrease towards the ends of the coils and the cross sections of the coils may differ, decreasing from coil 31 to coil 35. The number of turns may increase from coil 31 to coil 35 and the mid-points of the coils may be inter-connected. An iron shell 8 and iron insertions 9 may be provided as described in Specification 383,058. Each coil or section may consist of several coils joined in parallel and " screwed " in relation to one another in order to obtain uniform current distribution.
