Title: Article orienting apparatus
IPC: B65G47/24
Filed: 1956-10-05
Abstract: 797,331. Orientating articles. TRIGGS, W. W. (Mitchell Co., A. J.). Oct. 5, 1956, No. 30399/56. Class 78 (1). An apparatus for orientating buttons comprises a shoot 2 feeding disoriented buttons to rotor 20, sensing means 30 for sensing the orientation of the leading button, and driving means 80 controlled by the sensing means 30 for moving the rotor 20 in accordance with the sensed orientation so as to deliver the leading button oriented to shoot 12. As shown, buttons are fed disorientedly from rotary hopper 4 and slide along shoot 2 towards rotor 20. The two leading buttons are engaged by three devices, viz. pin 40, mounted upon plate 26, tip 56 mounted upon plate 50 and finger 66 mounted on detent 60. Thus, each of these devices is caused to pivot towards the leading buttons by the advancing movement of slide 70 to the left, the latter carrying cam surfaces 106, 116 and 110 which engage the parts 108, 120 and 114 of the respective devices to effect the respective movements. Additionally, the slide 70, by its advancing movement causes rotation of rotor 20, this rotation being effected in one of two ways, viz. either anti-clockwise by shoulder 80 engaging pin 82 on rotor 20, or clockwise by shoulder 96 engaging pin 98, the rotor being restored by spring 24. This choice of rotation is made by stud 36 carried together with pin 40 by bar 30 (Figs. 3, 4) pivoted at 32 to plate 26. If the first leading button is positioned as in Fig. 4, stud 36 is raised and, by engagement with pawl 92, causes shoulder 80 to rise, and to miss pin 82, thus permitting shoulder 96 to engage pin 98 and the slide advances, and to effect clockwise rotation of rotor 20. Thus, the said advancement of slide 70 causes finger 66 to position the leading button against cover 8 of shoot 2, and the pin 40 descends to contact said positioned button and in doing so positions stud 36, this positioning of stud 36 effecting the choice of the subsequent rotation of rotor 20. All buttons are therefore delivered one - by - one down shoot 12, tip 56 serving to retain the second leading button in shoot 2. The floor of each shoot 2, 12 is formed with grooves 16 (not shown) in order to minimize friction and to reduce any charge of static electricity induced on a button.

Abstract: 808,157. X-ray apparatus. PHILIPS ELECTRICAL INDUSTRIES Ltd Oct. 5, 1956 [Oct. 8, 1955], No. 30428/56. Class 98(1) In X-ray apparatus including two X-ray tubes for photofluorography, the tubes operate alternately and the photographic film for both tubes is moved after the energization of one tube and before energization of the other. As shown, an object 3 is traversed by rays from X-ray tubes 1, 2, forming images on screens 4, 5 which are photographed by cameras 8, 9. The camera film feed mechanisms are driven by a common shaft 12. An electric motor 13 drives a mechanism 16 having output shaft 17, 18. Shaft 17 rotates continuously, but shaft 18, which is geared to shaft 12, rotates only during one quarter of a revolution of shaft 17. Shaft 17 is geared through a 2 : 1 reduction bevel gear to a rotatable switch arm 21, which alternately closes switches 32, 33 to initiate action of time switches 30, 31 to energize tubes 1, 2 alternately. Between exposures the film is changed in both cameras. One film records the image due to the tube energized, while the other merely records scattered radiation.

Title: Etherification of vinyl phenol polymers or copolymers
IPC: C08F8/00
Filed: 1948-11-24
Abstract: Polymers and copolymers of ortho and meta vinyl phenols and their lower nuclear homologues are etherified by reaction with an unsaturated or saturated alkyl inorganic ester, e.g. dimethyl or diethyl sulphate, allyl or b -methallyl chloride, bromide or iodide but not fluoride.  Copolymers with compounds such as butadiene hydrocarbons, chloroprene, styrene compounds, vinyl naphthalenes, acenaphthylene, N-vinyl pyridine, cyclopentadiene, vinyl and vinylidene halides, vinyl esters, acrylic esters, acrolein, or allyl compounds may be used.  The polymer may be treated in a solution or dispersion in an alkaline polar medium, e.g. water or lower aliphatic alcohol or a non-polar medium, e.g. benzene or benzene-alcohol mixture, and in the latter case a quaternary ammonium hydroxide condensing agent is preferable. Films formed from a solution of the product in benzene containing tert-butyl hydroperoxide may be rendered insoluble on heating.  In a modification the polymeric resin is treated with both an aldehyde and an etherifying agent, together or separately in one or two stages to yield a thermosetting resin which may be used as a moulding powder when compounded with fillers, plasticizers and lubricants, or used as a lacquer or adhesive when in a solution or dispersion.  In examples poly-m-vinyl phenol, copolymers of m-vinyl phenol with styrene or methyl acrylate, and of o-vinyl phenol with styrene are etherified, the alkaline agents used being sodium hydroxide, methyl pyridinium hydroxide and tetramethyl ammonium hydroxide; and poly-m-vinyl phenol is reacted simultaneously with dimethyl sulphate and formaldehyde. Specifications 691,037, 691,038 and 691,040 are referred to.

Surrounding, but spaced apart from the axle is a sleeve 11 mounted in bearings 10, and having an annular chamber in which independent rings 12, 13 are rotatable. The rings 12, 13 have a few teeth 16 which engage with pinions 14 rotating on pivots 15 fixed in the sleeves. On the shaft 2 is rigidly fixed a yoke 17, the ends of the arms of which have spherical bearings 10 in housings 19 sliding in channels 20, 21, one in each ring 12, 13. The drive takes place through a pinion 22 engaging with a toothed wheel 23 rigidly secured to the sleeve 11, and thence through the rings and yoke 17. Vertical movement of the axle when the yoke is vertical is taken up by its longitudinal sliding in the slots 20, 21, whilst a vertical movement when the yoke is horizontal results in a slight relative rotation of the rings through the pinions 14 on their pivots 15. The casing 3 may be rigidly connected to the motor frame.

Title: Process for improving the mechanical qualities of glass
IPC: C03B25/02
Filed: 1953-11-09
Abstract: 782,502. Glass, manufacture of. SOC. ANON. DES MANUFACTURES DES GLACES ET PRODUITS CHIMIQUES DE ST. GOBAIN CHAUNY & CIREY. Nov. 9, 1953 [Nov. 15, 1952], No. 31003 /53. Addition to 774,673. Class 56. The process of the parent Specification is applied to the manufacture of flat glass by continuous extraction of sheet glass from a fusion furnace, the heat flux being applied to the external layers of the glass at locations and with an intensity at such locations determined as a function of the temperature distribution at the surface of the sheet and of the deformations of the surface. The heat flux may be uniform and applied along an isotherm of the surface or may be applied along any line, in particular a straight line perpendicular to the direction of motion of the sheet, and be regulated as a function of the temperatures of the different points of application. Where the two faces of the sheet do not follow the same law of cooling, the heat fluxes may be regulated accordingly or thermal insulating means and/or auxiliary reheating means may be utilised. The apparatus shows a sheet of glass 1 flowing out from a melting furnace 2 between two laminating rollers 3 and over conveyer rollers 4 to a cutting table 5. A heat insulating screen 6 disposed above the sheet 1 is formed with a recess 7 which may be covered to any desired extent by a movable element 8 and is provided with electric heating resistances 9 at its edges. A carriage 12, movable on rails 13 alongside the moving glass sheet 1, carries burners 10, 11a and 11b, the upper face, which normally cools more rapidly, being subjected to the heat fluxes from the set of burners 10 to bring both faces of the sheet to the same temperature and the burners 11a, 11b being arranged to act simultaneously on the two faces of the sheet. The burners are arranged in a generally concave shape, to correspond to the isotherms of the glass sheet and the burners 10 are slightly raised towards the middle to take into account the curvature assumed by the sheet as shown in Fig. 4. The burners are constituted by a plurality of elements individually controllable in position and intensity.

Abstract: 963,028. Ventilators; lamps combined with ventilating apparatus. EMERSON ELECTRIC MANUFACTURING CO. Aug. 29, 1961 [March 30, 1961], No. 31045/61. Headings F4R and F4V. A combined lighting and ventilating unit mounted in a false ceiling 24 comprises a casing 11 in which fluorescent lighting means 20 are secured, the casing being enclosed at its central portion by a further casing 42 through which conditioned air is supplied to the room while stale air is exhausted to a plenum space above the ceiling 24 through the casing 11. Conditioned air supplied to the casing 42 by a pipe 43 leaves the former via apertures 46 in flanges 14 at the sides of the casing. Communication between the interior of the casing 11 and the plenum space is effected by means of apertures 47 in caps 15 at each end of the casing, the latter and the room space being in communication via apertures 52 in the end flanges 17. Extracted air is caused to enter the casing at one end and be discharged at the other by means of sliding dampers 48 which are positioned to close aperture 47 and open aperture 52 at one end of the casing and open aperture 47 and close aperture 52 at the other. The open bottom of the casing is closed by a light-transmitting sheet 22 having an infra-red radiation reflecting layer. Depending on the positions of the dampers 48 the units may be used to supply air to or exhaust air from a room or a combination of both as above. In the system shown in Fig. 9 for ventilating two rooms S and S<SP>1</SP> having a common plenum chamber, units 10 supply air to and withdraw air from room S while units 10a serve only to withdraw air from room S<SP>1</SP>. Air from the plenum space is extracted via a duct 32 by two fans 30 and 31 which direct respective streams of air over the condenser 34 and evaporator 37 of a heat pump circuit. Part of the warm air stream is supplied through pipes 28 and 29 to the units 10 and part through pipe 35 to a chamber 36 which is also supplied with cold air through line 38. Air is discharged directly from chamber 36 into room S<SP>1</SP>. In the modifications of Figs. 5 to 7 (not shown), the infra-red reflecting layer is separate from the sheet 22 and takes the form either of a single layer placed directly beneath the lights 20 or of an individual cup-shaped reflector for each light. The apertures 47 and dampers 48 may be omitted and replaced by ports in the top wall of the casing 11 for communication with the plenum chamber. The casing 11 is coated with a heat insulating layer.

Title: Improvements in and relating to thermionic valves and circuits for the generation, modulation and controlling of electric oscillations
IPC: H03B5/10
Filed: 1931-06-30
Abstract: 380,144. Valve generating and modulating circuits. HODGSON, A. D'A., 24, Spenser Road, Bedford. June 30, 1931, No. 31372/30. [Class 40 (v).] A valve generator with two or more grids has a frequency -determining circuit connected between two of the grids, and its output circuit connected between anode and cathode, so that changes in the output circuit do not affect the frequency. As shown in Fig. 2, the frequency-determining circuit 5, 6 is connected between the inner grid 1 and the second grid 2, a third grid 3 acting as a screen and preventing negative-resistance effects. An intermediate point of the coil 5 is connected to the cathode F, and suitable positive voltage is applied to the grid 2 and the anode AN. The output circuit 9, 10 is connected across anode and cathode and is coupled to an aerial or other load circuit. The anode may be connected to a tapping on the coil 9. A neutralizing condenser may be connected between the anode and either of the grids 1, 2 ; or neutralization may be effected by adjustment of the cathode tapping X on the coil 5. The anode current may be given various wave-forms by adjusting the swing of voltage on the grid 2, and multiple frequencies may be obtained in the anode circuit. Modulation may be effected by applying signal voltage to the grid 3, or to the high-tension supply lead for the grid 2. A modulating tone-frequency may be generated by the transmitter valve by back-coupling the anode circuit at 18, Fig. 8, to the circuit of the grid 3, which may include a key 5 and a source of low positive voltage. The tone-frequency may alternatively be generated by back-coupling the tuned-anode circuit 16, 17 to a coil 18<1> in the circuit of the grid 2 as shown in Fig. 9 ; or the coil 18<1> may be tuned.
