Filed: 1973-08-09
Abstract: 1473104 Cyclically operating reciprocating conveyers GLASS TUBES & COMPONENTS Ltd 19 July 1974 [9 Aug 1973] 37844/73 Heading B8A Groups of objects, e.g. glassware, are transferred from a first conveyer to a second, e.g. lehr, conveyer by a machine 10 in which a carrier 11 is moved vertically and horizontally in a cam-controlled cycle. The carrier is detachably supported on an arm 12 which is mounted on a carriage 16 vertically movable by a motor 20 located on the main frame of the machine. A drive pinion 22 engages a vertical rack 23 secured to the carriage 16. The arm 12 is horizontally movable by a motor 28 (Fig. 2, not shown) also mounted on the main frame, the drive comprising a rack 36 on the arm 12 driven by gearing 30 connected to the motor by pin-and-slot means 39 in a vertical shaft 29. This permits drive in various vertical positions of the carriage 16. Both motors 20, 28 are reversible and variable in speed. For controlling the sequence and duration of the steps I-VI (Figs. 3 and 4, not shown) of the movement, the mechanism comprises a set of cams 62<SP>I</SP>- 62<SP>VII</SP> each fast with a respective gear 60<SP>I</SP>-60<SP>VII</SP> of a gear train driven by a variable speed motor 61. Cam followers 63 actuate microswitches 65 which control the motors 20, 28. A photo-cell actuated by a group of articles initiates operation of the control motor 61. By replacing the cams with cams having different dwells the various periods of each transfer cycle may be changed. Further cams and switches may be added to achieve a more complex cycle of movements. Instead of the vertical and horizontal movements being in turn, the main motors 20, 28 may operate simultaneously.

Title: Rejection filter circuit
IPC: H03H7/01
Filed: 1971-08-18
Abstract: 1355098 Rejection filters A KATHREIN SNR 18 Aug 1971 [21 Aug 1970] 38697/71 Heading H1W A high-frequency band rejection filter comprises a transmission line element extending between input and output 11, 11<SP>1</SP>, two (or more) shunt elements 12, 13 series resonant at the rejection frequency or frequencies, and at least one quarter-wavelength (nominally) transforming section 14 electrically equivalent to a T-section filter for matching the impedances of the shunts to that of the line. The conditions for matching are discussed in the Specification. The shunt circuits may consist of resonant lines K1, K3, off-tuned inductively, in series with respective capacitances C1, C4. Each may be realized by a resonator 31, 32, Fig. 8, of, e.g. coaxial or printed-circuit construction, coupled by stray capacitance (providing C1, C4) to the uninterrupted line conductor 34. The transforming section similarly includes an inductively offtuned resonant section K2 and series capacitances C2, C3. This is realized in the manner shown in Fig. 7 where the resonator 24 is coupled to the interrupted line 25, 26 by capacitances between the inner conductor 29 and electrodes 27, 28 attached to the line. The resonators may be capacitatively tuned and the capacitances C1, C2, C3, C4 may be adjusted by moving slugs or electrodes attached to the transmission line.

Title: Radiation pyrometers
IPC: G01J5/04
Filed: 1975-09-22
Abstract: 1506487 Radiation pyrometer INTERNATIONAL HARVESTER CO 22 Sept 1975 38772/75 Heading G1A Apparatus for measuring the temperature of a body 34 comprises means 50 for conducting radiant energy from the body, a plurality of radiation detectors 168, 170 for generating signals with different characteristics and signal processing means 192 operable to give signals indicative of temperature, in a first mode to use the signals from the detectors such that the detector sensitivity is high relative to that of a second mode in which the detectors are insensitive to changes in transmission characteristics of the optical path from the body to the detectors, means 192 including means 206, for adjusting the magnitude of the first mode signal, and being operable in the second mode to provide a calibration signal. The apparatus includes casing 38 fixed to housing 40 of a turbine engine and containing interface collimator 46, lens 48, which acts as a seal, and fibre optics device 50. Clean compressed air flows through apertures 62,  64 and tubes 58. Lens 182, Fig. 8 focuses the radiation on to silicon diode photovoltaic detectors 168, 170 via interference filter 184, transmitting radiation between 0À55Ám and 1Ám and reflecting the rest. In the embodiment of Fig. 13 (not shown) the plane of the interference filter is perpendicular to the fibres of device 50 and located between parallel detectors. In the first mode the logarithmic output signal from detector 170 goes via input 195, linearizer 212 and mode switch 214 to digital voltmeter 194 giving a temperature reading and/or is employed as a control signal. In the second mode the logarithmic output signal from detector 168 goes via input terminal 216 to voltage divider 220 giving the ratio of the detector signals through linearizer 222 to voltmeter 194. When the temperature has been read in mode 2 gauged resistors 206, 206a are adjusted to obtain the same temperature reading in mode 1. The two detector signals may be summed for mode 1 operation. The optical signal can be split into more components as in an embodiment using a prism as beam-splitter, Fig. 11 (not shown), and any number of detector output signals summed for the first mode. Multiple ratio signals may be generated in mode 2. This prism prevents longer wavelength radiation heating up the detectors. Fig. 6 shows an interface device usable instead of collimator 46. Cylindrical casing 84 contains annular plenum 92 and frustro-conical flow directing baffles 94a-e with apertures 96a-e, through which radiation from a turbine bucket passes. Purge air supplied to plenum 92 flows through openings 104, 106 and 108. Air leaving nozzle 102a crosses the surface of interface window 85 and is entrained in that leaving nozzles 102b, 102c through openings 96b-d into the turbine (arrows 111). Hollow stators, Fig. 7 (not shown), in a turbine may house fibre-optic devices opposite different parts of the turbine buckets 34, and cleaned by cooling air in the hollow. These convey radiant energy to the beam-splitters and detectors.

Title: Hydraulic extrusion press

Filed: 1959-11-19
Abstract: 935,692. Extruding. HYDRAULIK G.m.b.H. Nov. 19, 1959 [Dec. 5, 1958], No. 39243/59. Class 83 (4).  An hydraulic extrusion press has its extrusion plunger 4a advanced to a preselected stroke position and then moved rapidly to perform an impact extrusion stroke by pressure from an hydraulic accumulator 10 acting on the main press piston 4, and a retraction cylinder 7, for retracting the piston and plunger, is connected permanently to the accumulator through a pipe 9 and one-way valve 6 which during the initial part of the extrusion stroke causes pressure in cylinder 7 to build up until it opens the valve 6 and thus causes rapid movement of the plunger 4a. The latter is first advanced to a distance s from the billet 1 by pressure from an air reservoir 16 admitted to piston space 8 through pipes 17, 14 and valve 18; cylinder space 7 is meanwhile connected to exhaust through valve 12. The latter is then closed and an inlet valve 15, actuated by a piston 22 controlled by a pilot valve 19, is opened to admit pressure liquid from accumu-  lator 10 into cylinder 8. The resulting movement of pistons 4, 5 pressurizes the liquid trapped in cylinder 7 which is released ultimately through valve 6 whereby the plunger 4a impact-extrudes billet 1 through die 2a. The pistons are subsequently retracted by admitting pressure liquid from accumulator 10 into cylinder 7 through valve 13 and pipes 23, 11.

Abstract: 1,102,055. Stabilizing pulse oscillators; pulse modulation circuits. COMPAGNIE FRANCAISE THOMSON HOUSTON - HOTCHKISS BRANDT. 14 Sept., 1965 [16 Sept., 1964], No. 39294/65. Headings H3T and H4L. In a pulse generator of the type where a capacitor is charged through a transistor and then triggers a unijunction transistor, so that the pulse repetition rate depends on the input voltage to the transistor, the circuit is stabilized against temperature changes by (a) providing at the transistor emitter a voltage which is always equal to the emitter-base voltage, and (b) providing a second unijunction transistor to compensate for emitter-base or base-base voltage changes of the first unijunction. In Fig. 3, the input voltage to transistor 10 is also passed to transistor 40 whose collector load R4 is half the value of the emitter load R1. A third transistor 30 (identical with 10) is used as a diode and receives a current through R4 of opposite sign and twice the value of that through R1. The emitter-base voltage of transistor 30 is therefore always equal and opposite to the emitter-base voltage of transistor 10 and the collector current of the latter does not therefore change with temperature. The charging rate of capacitor C is thus stabilized. The triggering point of the unijunction 20 is stabilized by connecting the upper base to earth through a variable resistor R7 and a second identical unijunction 50 used as a diode. Temperature changes tend to alter the baseemitter and base-base voltages of the unijunction 20. The base-emitter voltage variations of the two unijunctions are equal and opposite, and the effect of the second unijunction reduces the variation of triggering voltage by about half, assuming an intrinsic ratio of 0À5. The base-base voltage variations of unijunction 20 are opposed by the variations in the current through R7 and unijunction 50, and accurate compensation can be obtained by adjusting R7; the setting of the latter may be at zero resistance. Resistor R1 may be made variable to increase the frequency range for change in input voltage E.
