Abstract: 1518943 Gas sensors LUCAS ELECTRICAL Ltd 18 Aug 1975 [10 Sept 1974] 39357/74 Heading GIN A device, for monitoring the composition of the gaseous exhaust emission of a combustion process, includes an insulating substrate, in the form of a ceramic tile 32, which is inert to the gaseous exhaust emission being sensed at the elevated operating temperature (700-1000‹C) of the device, a metal oxide sensing element 31 being printed on and adhered to one major surface of the tile adjacent one end of the tile to be exposed, in use, to the exhaust emission. The metal oxide is chosen so that at the operating temperature its electrical conductivity varies with the concentration of oxidizing or reducing constituents in the exhaust emission, and a heater in the form of a heating wire 42 of platinum is wound around the substrate. The ceramic tile sensing element and heater are surrounded by a hollow, heat resistant body defining a shroud which extends around the sensing element to prevent the exhaust emission flowing directly over it in use. A pair of elongated conductors 33a provide electrical connections 33b to the sensing element. The conductors being printed on and adhering to the one major surface of the tile and extending from the sensing element towards the other end of the tile. Alternatively Fig. 2 (not shown) the heater (55) is a printed resistive area on the opposite surface of the substrate from the sensing element. Or, Fig. 3 (not shown) the resistive heater area (62) and the sensing element (63) are printed spaced apart on the same side of the tile. The metal oxide may be titanium dioxide, zinc oxide, nickel oxide or gallic oxide. A preferred application of the device is in an internal combustion engine to control the fuel/air mixture in dependence on the composition of engine exhaust emission. The element 31 may be heated to a constant temperature using thermocouples adjacent the element for accurate sensing.

Abstract: 828,757. Determining particle size distribution of materials. PILLSBURY MILLS Inc. Dec. 23, 1957, No. 39920/57. Class 106 (2). Apparatus for determining the particle size distribution of finely-divided material comprises a tube 10, the lower end of which is closed and is of reduced bore, a hollow member 16 forming a dispersing chamber and being of a suitable size to be removably inserted into the upper portion of the tube 10 and having a stop 18 to position its lower end a fixed distance below the top of the tube 10. The lower portion of the tube 10 is provided with graduations 10d, and the lower end of the member 16 has a dispersing screen 17 mounted thereon. In operation, a sedimentation liquid, e.g. benzine, is placed in the tube 10, the amount used being sufficient to reach to the lower end of the member 16 when this is inserted in the tube. The lower end of the member 16 is closed, e.g. by the operator's thumb, and is partially filled with the powder being tested, such as flour. The member 16 is then nearly filled by a suitable dispersing liquid, whose specific gravity should be slightly less than that of the sedimentation liquid, and the chamber shaken, the operator's finger closing the upper end. Thereafter, the thumb is removed and the member 16 inserted in the tube 10. The finger is then also removed and the member 16 withdrawn from the tube. The depth of powder settled at the bottom of tube 10 is noted at predetermined times and from this the particle size distribution can be calcuated. For particles of a size less than thirty microns, the tube 10 is placed in a centrifuge to speed the rate of settlement. In the case of materials such as clay, a high-speed electric mixer is used to mix the material and the dispersing liquid in the member 16. In this case the sedimentation liquid is distilled water and the dispersing liquid can be a solution of sodium silicate in water to which acetone has been added.

Title: Surface-processing method for synthetic resin sheet
IPC: B05D5/06
Filed: 1965-09-29
Abstract: A method of processing the surface of a synthetic resin sheet comprises rolling the sheet with a hot roller whilst applying additional resin in a manner such that the additional resin is brought to a molten state by the temperature of the roller and cause to adhere in that state partly to the roller and partly to the sheet, and thereafter separating the sheet from the hot roller whilst the additional resin is in the molten state, thereby forming spiniform, hair-like or similar projections on the sheet from the additional resin.  The additional resin may be in the form of a powder which may be applied to the roller or to the surface of the sheet in front of the roller.  The rolling may be carried out by passing the sheet through a pass formed by the hot roller and a cooled roller spaced parallel therefrom.

Title: Malfunction detecting apparatus for use in a crt deflection circuit
IPC: H04N3/20
Filed: 1976-10-06
Abstract: 1527428 Protective circuits for cathode-raytubes SONY CORP 6 Oct 1976 [20 Oct 1975] 41573/76 Heading H4T In order to prevent dangerously high levels of EHT in a television circuit, the flyback transformer is associated with separate means for detecting excessive voltage and high-frequency components in the flyback pulse, such means being coupled by a feedback circuit to the horizontal drive circuit in such manner as to reduce the level of the pulses. As shown, deflection coil 10 and S-shaping capacitor 11 are connected in series with the primary 6a of a flyback transformer forming part of a horizontal deflection circuit which also includes a switching transistor 7, damping diode 8 and a capacitor 9 resonant with the primary winding 6a during flyback periods. During such periods, a single pulse is produced which is effective through secondary winding 6b and rectifier 16 to produce EHT for the tube 17. Should capacitor 9 become disconnected, the flyback pulse will contain high-frequency components and excessive EHT will be generated. Such components are detected by a circuit comprising high-pass filter 21 and rectifier 25 which produce a voltage at the base of transistor 26 sufficient to switch on the transistor. The collectoremitter circuit of transistor 26 is connected to a source 20 of D.C. voltage V cc  derived from an auxiliary winding 6c of the flyback transformer. When the transistor is turned on, a voltage proportional to V cc  is applied to the control loop 12, 13 of the horizontal driver 15 and is effective to reduce the sweep period. This, in turn, is effective to reduce the rate of change of current in the primary 6a during flyback and thus to reduce the size of the flyback pulse. The winding 6c is also used to detect excessive values of the supply voltage + VB. Should the value of V cc  exceed the threshold of Zener diode circuit 28, 29, a voltage is again applied to the loop 12, 13 and is effective, as explained above, to reduce the flyback pulse. Alternatively, the voltages detected by the HP filter 21 and the winding 6c may be used to inhibit the oscillator 12.

Abstract: 1282924 Fluid logic and switching circuits PLESSEY CO Ltd 18 Aug 1970 [23 Aug 1969] 42117/69 Headings F1G and F1P An actuator piston 25 is held in one or other extreme position according to whether output leg 20 or 22 of a fluidic device 6, e.g. a bi-stable element having a supply input line 8 and control inlets 12, 14 is pressurized; control inlet 14 being supplied at a pressure PR from a Venturi tube 18 which receives fluid from a source 16 at a pressure PV which is proportional to supply input pressure P 4  whereby the output is switched from leg 20 to leg 22 when the ratio of P 4  to PF reaches a predetermined value. As shown the Venturi 18 is fed from a vent of the interaction volume of the element 6 and when due to an input pressure rise and hence an increase in vent pressure PV sufficient to choke the Venturi throat the resulting rise in pressure PR in control input 14 switches the output from leg 20 to leg 22. The actuator piston 25 then closes a switch 26 which may control the fuel supply to a turbine having a high-pressure stage 7 and a fan stage 9 which respectively provide the supply pressure P 4  and control pressure PF. Alternatively the switch 26 may control an air valve 13. In a modification the Venturi is supplied directly from the high-pressure supply and in a further modification the fluidic element is a proportional amplifier (32), Fig. 3 (not shown).

Abstract: 1,105,463. Digital electric computers. WESTERN ELECTRIC CO. Inc. 6 Oct., 1965 [7 Oct., 1964], No. 42349/65. Heading G4A. A digital electric data processor includes means (a) for decoding a first instruction to perform a first operation (b) for decoding a second instruction to perform a second operation and (c) for decoding a third instruction to perform both the first and second operations, wherein the first and second operations are performed on data held in a first plurality of locations and the third operation is performed on data held in a second plurality of locations fewer in number than the first plurality. As described with respect to Figs. 1 and 2, not shown, instruction and data words having 28 bits are held in a store (18) having 2<SP>23</SP> locations normally addressed by bits 22-0 of a word. Instruction words are read'into an order word register (10) where the instruction bits 27-23 are examined by a decoder-distributer (12). The instruction bits can be decoded to perform orders Read, Write, Transfer wherein the address in store is specified by bits 22-0 of an instruction word and a Shift order wherein bits 22-14 are required to specify which register is to be shifted, whether left or right, and how many places. A combined order as described incorporates the shift and a read, write or transfer order in the one word, the Write, Transfer or Read orders being situated in bits 27-23 and the shift order occupying bits 22-14 leaving 13 bits useable to define an address. Thus words to be operated on by a combined order must be situated in the least significant 2<SP>14</SP> memory locations. The memory may comprise a magnetic tape unit associated with a magnetic core matrix. Instructions are usually situated in adjacent memory locations a " plus one " adder connected to the programme address register defining different addresses. However a transfer operation allows a different address to be inserted in the register. Words being operated on may be passed through a masking circuit, masking being controlled by the contents of a masking register. The decoder-distributer is illustrated in more detail in Fig. 3 (not shown).
