Patent GB-1021841-A (GB)
Title: Method and apparatus for supporting glass sheets
IPC: C03B35/16
Filed: 1962-09-19
Abstract: <PICT:1021841/C1/1> <PICT:1021841/C1/2> <PICT:1021841/C1/3> Glass sheets are supported during heat treatment on a layer of gas so as to prevent injury due to engagement with solid supporting and feeding members.  The sheet of glass is fed by a roller conveyer 20 to a pre-heating bed 30, where it is heated by upper and lower electric elements, and its further progress is effected by means of edge-engaging rotary discs 37.  The bed 30 is succeeded by a number of gas-support heating sections 2, a quenching section 3 and a delivery section 4.  The bed 30 and the beds of the sections 2 are formed by a series of elements 31 forming open-ended chambers arranged in rows obliquely-disposed to the direction of movement of the glass.  Each element is provided with a hollow stem 32 entering a reservoir 35 to which hot gas under pressure is supplied. The upper end of the stem is closed by a plug 150, various forms of which are described, whereby the gas is caused to enter the chamber through small transverse holes 151 or past other obstructions so that a diffused flow is produced and direct impingement of a jet on to the glass is avoided.  The elements are spaced apart so that outflow passages to the atmosphere are provided.  The pressure of the gas is such that it maintains the glass sheet at a short distance above the tops of the elements.  The elements are normally arranged with their upper surfaces in a plane, but they can be adjusted to present a curved bed to enable bent sheets to be produced. In the quenching section, a bed of elements is arranged above and below the glass and the elements are supplied with cooled air and are constructed so as to present towards the glass a larger mass of metal to provide enhanced heat-transfer properties.  The upper bed of elements can be raised to facilitate cleaning and adjustment. Progress of the glass through the quenching section is effected by edge-engaging discs 370 similar to the discs 37.  When the leading edge of a glass sheet passes over a pressure-sensing element located near the end of the heating sections, the last three discs 37 and the discs 370 are disconnected from the driving motor and connected to a high-speed motor so as to speed the delivery of the sheet from the heating section to the quenching section, the normal drive being resumed after a predetermined time interval. The apparatus can be used in tempering, annealing, bending, and coating glass as described in Specifications 1,021,842, 1,021,843, 1,021,845, 1,021,846, 1,021,847, 1,021,848 and 1,021,852.

Title: Electrohydraulic control of a hydraulic actuator
IPC: F15B18/00
Filed: 1971-07-29
Abstract: 1344373 Fluid-pressure servomotor systems MESSERSCHMITT-BOLKOW-BLOHM GmbH 29 July 1971 [21 Aug 1970] 35818/71 Heading G3P A hydraulic actuator is controlled by a spool valve 2, Fig.1, having one end subjected to pressure from a motive fluid supply 8 and the other end connected by a common line 4 to two or more servovalves 1 which also supply signals to an error monitoring system. The servovalves are operated by solenoids 16 and have their outputs from ports 12 connected to a comparator 13 which connects a pressure port 20 through an orifice 25 to a drain 23 when the pressures from the ports 12 are unequal. The change in pressure operates a warning device or a safety circuit. The circuit shown in Fig. 1 may be duplicated and the outputs from the two comparators fed to an AND gate so that the system continues to operate if only one circuit develops a fault. A further modification is shown in Fig.3 in which the outputs from three comparators 59 are fed to an AND gate 60 so that no safety switching operation occurs until two spurious servovalve output signals are produced. The warning device shown in Fig. 4 may be interposed between each comparator and the AND gate when the circuit of Fig. 1 is duplicated and has outlets 67 and 68 connected to the comparator and the AND gate, respectively, while a third outlet 69 supplies the servovalves from a pressure source 65. When the comparator reduces the pressure in outlet 67, a spool 71 is moved to the left by the supply pressure so that the servovalves are connected to a drain 66. An orifice 72 prevents pressure fluid flowing to drain through the comparator. The spool 71 is returned by the spring 73 when a solenoid valve 70 is de-energized for a brief period. The supply to the servovalves may alternatively be discontinued by de-energization of the solenoid valve 70. In modified forms of the warning device, the spool is first displaced by flow through a restrictor, the solenoid valve is replaced by a pair of valves or by a valve which can be energized to move to either side of a neutral position. In the last modification, a delay valve is also provided to isolate the line 67 from direct connection with the pressure medium inlet while the spool is re-set. The line 67 is recharged through a restrictor and the spool is retained in the re-set position only when the outlet pressures from the servovalves are again uniform. The lines 68 from the warning devices may be connected as shown to the duplicated AND gate of Fig.17 in which failure of pressure in either the upper or lower pair of lines 68 causes loss of pressure in the other pair through lines 131 so that springs 126 operate safety switches 128 through plungers 122...125.

The resonators and transducers of an electromechanical filter are supported from a surrounding frame. The resonators 1 and (electrostrictive) transducers 2 (Fig. 1) operate in a half-wave longitudinal mode (or in a harmonic mode) and are coupled to each other and to a ceramic frame 3 by wires 5. These are spotwelded to the filter elements and to metallized portions 4, 6 of the frame. The metallized portions 6 may be notches. The wires may be looped around the frame as shown in Fig. 4. In this embodiment, the frame 3 is made of deformable metal and, during location of the coupling wires, the filter elements 1, 2 are held in short grooves in the side members. Subsequently, the end members are expanded and the side members bent to the form shown in Fig. 5. In an alternative method of manufacture, the coupling wires and frame are temporarily secured to guide components on e.g. the welding machine. The filter may be completely enclosed by the addition of top and bottom closure members. Additional resonators 8, resonant above or below the band pass of the filter may be used to decouple the transducers 2 from the frame 3.

Title: Colour Television Signal Separation System
Inventor: PARKER NORMAN WILLIAM
IPC: H04N9/78
Filed: 1968-07-30
Abstract: 1,188,612. Colour television. MOTOROLA Inc. 30 July, 1968 [11 Sept., 1967], No. 36367/68. Heading H4F. In a colour television system utilizing a luminance signal having a bandwidth which partially overlaps that of a colour sub-carrier, in which the phase of the sub-carrier alternates from line to line, a bandpass filter 24<SP>1</SP> selects the colour sub-carrier and supplies it to an adder 26, where it is combined with the phaseinverted sub-carrier signal corresponding to the preceding line selected by means of a 1-line delay device 28 and a phase inverter 29. The output from the adder 26 across a variable resistor 33 is thus the pure colour sub-carrier signal, since the overlapping portions of the luminance signal in the two lines cancel one another. According to the embodiment, the output of the adder 26 may also be phaseinverted at 52 and added to the full bandwidth luminance and colour sub-carrier signals in an adder 50, so that the colour sub-carrier is cancelled and a pure luminance signal is obtained across a variable resistor 57. A delay device 42 compensates for the delay occurring in the filter 24<SP>1</SP>, delay device 28 and inverter 29. The pure sub-carrier output from the resistor 33 is phasesplit at 62 and applied via a transformer 60 to two lines 64, 65 of a red demodulator circuit 68. The pure luminance signal from the resistor 57 is applied to a centre tapping on the secondary windings of the transformer 60, and is thus supplied unbalanced to a pair of diodes 88, 92 of the demodulator circuit 68, to which opposite phases of the colour sub-carrier are supplied. Spurious modulation components of luminance at the colour sub-carrier frequency are thus cancelled. A reference oscillator 85, synchronized by a signal from the bandpass filter 24<SP>1</SP>, provides reference sub-carrier frequency signals of appropriate phase to the red demodulator 68 and to the blue and green demodulators 69, 70, which differ from the demodulator 68 only in the value of an amplitude determining resistor 99. The individual colour signals are finally supplied to a 3-beam shadow mask type cathode ray tube 24.
