Filed: 1974-05-23
Abstract: 1423117 Making glass beads POTTERS INDUSTRIES Inc 23 May 1974 [18 June 1973] 23194/74 Heading C1M Glass beads are produced by contacting at least one falling stream of molten glass 16 with the blades 30 of a rotating chopper wheel 20, a fluid being applied to the individual blades 30 to provide a fluid cushion over the portion of each blade which contacts the molten stream, thereby preventing sticking of the glass to the blades. The fluid is preferably steam. The blades are porous and are composed of carbon, silica glass or quartz. In one embodiment (Fig. 4) steam contained in a chamber 45 within the wheel escapes through a hole 50 just in front of the glass contacting face 33 of the blade 30. Alternatively (Fig. 5) a radially inner part of the blade 30 extends into the chamber 45 and the rearward face 32, of the blade coated in an impervious glaze 68, so that the fluid is directed through the pores of the blade and on to the forward face 33. The blades are stated to produce cylinders 60 of molten glass each having similar length and diameters which are subsequently formed into spheres by surface tension forces.

Title: Photometric analyzer
IPC: G01N21/53
Filed: 1973-05-16
Abstract: 1429198 Photometric gas analyzer ITT INDUSTRIES Inc 16 May 1973 [17 May 1972] 23313/73 Heading G1A The invention relates to apparatus for measuring the constituents of flue or stack emissions. The apparatus includes a perforated tubular probe 21 which is mounted in the stack. Light from a mercury lamp 23 is directed through the probe to be reflected back by mirror 27, to pass through a filter wheel 28 to a photo-multiplier 51 whose logarithmic response is used in the measurement by the use of a Beer's law calculation of absorption of light by the different constituents. The apparatus has a pressurized air input 30, which is fed along the sides of probe 21 and used to form air curtains in front of the windows covering mirror 27 and the housing 22, and an input 31 to provide purging of the probe with clean air for calibration purposes. The filter wheel 28 is provided with five filters, two identical ones for use in e.g. SO 2  measurement, two identical ones for e.g. NO 2  measurement, and a reference filter corresponding to a wavelength unaffected by either NO 2  or SO 2 . One each of the first two pairs is coupled with a neutral filter which cuts down the intensity by 1000 times to provide for calibration. The filter disc continuously rotates and its rotation is sensed by magnetic pick-ups 42, 43 and used by gating circuits 55', Fig. 6, to control the delivery of photo-multiplier output signals which have all been inverted in amplifiers 80-81", except for the reference filter signal which is delivered direct, through sample/hold circuits to the comparison circuit. The sample/hold circuits 57'-61' correspond to the five filter positions. In the calibration mode, a purging gas is passed through the probe and no absorption takes place therein. The filter outputs for SO 2 , NO 2  are compared with reference filter output by summing amplifiers 121', 122' and indicated at 123', 124' the switches 102', 103' being in their dotted positions. Potentiometers 88', 86" are varied to give zero values on the indicators. A range adjustment for the indicators is made by adjusting 116', 119', when the switches are in the solid position and the "calibration" SO 2 , NO 2  filters (i.e. those with additional neutral density filters) are being compared with the reference. For actual measurement, the probe is allowed to fill with flue gas and the switches are in the dotted position. The indicators may be voltmeters, or recorders or a process control may be provided. The instrument can provide smoke density or turbidity measurement. Besides visible light, ultraviolet or infrared wavelengths may be used.

Abstract: 828,050. Hypodermic syringes. ROEHR, Z. M. July 21, 1958 [July 25, 1957], No. 23331/58. Class 81 (2). A cover for a hypodermic needle has means interengaging with the hub of the needle so that relative rotation is prevented and the needle can be applied to a syringe without removing the cover. In the example described the hub 8 of the needle bears against four triangular ribs 21 projecting radially inward from the wall of the cover 20 and these ribs fit between four webs 17 formed on the neck 7 of the needle hub 8. By this means the needle may be applied to the nozzle 30 of a syringe and, if necessary, rotated to engage the locking device without removing the cover. The cover may similarly be used when removing a needle to avoid contamination. For storage purposes the open end of the cover 20 is closed by a cylindrical cap which may be heat sealed to the cover around its edge, this seal being broken when the needle is to be used.

Abstract: 317,477. Naamlooze Vennootschap Philips' Gloeilampenfabrieken. Aug. 18, 1928, [Convention date]. Void [Published under Sect. 91 of the Acts]. Gauging-apparatus.-The movement of a body is determined by means of a device comprising an oscillatory circuit which is electrostatically influenced by the body and provided with means whereby this influence is made perceptible. Embodiments of the invention are described for ascertaining the speed of a rotating shaft and for determining the irregularities in the windings of the helical wire used in the manufacture of incandescent lamps. The oscillatory circuit, as shown in Fig. 1, includes the primary of a tapped transformer 1, a thermionic valve 3, and a circuit A consisting of an inductance 4, a variable condenser 5, a fixed condenser 7 and a neon tube 6. In the application to a rotating shaft, the shaft 10, Fig. 2, carries an electrode 11 co-operating with a stationary electrode 12 to form a condenser connected in parallel with the variable condenser 13 of an oscillatory circuit as shown in Fig. 1, and including an inductance 14 and neon tube 15. The shaft may carry a disc 32, Fig. 5, with a segment 33 having a different dielectric constant from that of the other parts of the disc and arranged to rotate between a pair of electrodes 30, 31 in the oscillatory circuit. The condenser 7, or electrodes 11, 12 or 30, 31 may be so chosen that when the capacity reaches its maximum value the oscillatory circuit is in a state of resonance and the neon-tube is illuminated. As shown in Fig. 7 applied to the intermittent illumination of a continuously moving helical wire the winding mechanism for the helix 25 is geared to a shaft 41 carrying an electrode 42 cooperating with another electrode 43 and adapted to illuminate the helix 25 by the neon-tube 35 each time the helix moves a distance equal to its own pitch. The helix is viewed through a microscope 36 and will appear to be stationary if no irregularities are present.

Abstract: 929,232. Automatic frequency control systems. BLAUPUNKT-WERKE G.m.b.H. July 10, 1959 [July 12, 1958], No. 23707/59. Class 40 (5). In a single sideband television receiver, with the nominal video carrier on one sloping flank of the receiver I.F. pass-band, an additional voltage derived from detected synchronizing pulses is added on to the output of a frequency discriminator tuned to the video carrier for A.F.C. of the local oscillator. Thereby the frequency control range is increased and ambiguities due to more than one zero of the discriminator output avoided. (The rectified sync. pulse amplitude is also dependent on frequency drift.) An additional step-wave voltage arising only when a certain frequency drift is exceeded may be derived from a phase discriminator 58 with inputs 56, 57 receiving sync. pulses from a sync separator stage and sweep voltages from a line output stage respectively and with one output 59 stabilizing a flywheel sync. oscillator controlling the line scan, the other output at 69 being added to a constant positive D.C. voltage and the output of a frequency discriminator 5 tuned to the video nominal I.F. frequency, and the combined output applied to a phase splitter 6 with outputs applied across a rectifier 61 constituting a variable capacitance in the tuned circuit of a local oscillator 60.
