Abstract: 1314374 Mounting piezoelectric resonators MARCONI CO Ltd 24 Aug 1970 [15 Sept 1969 3 Aug 1970] 40609/70 Heading H1E A method of mounting a piezoelectric crystal having aluminium electrodes in order that the tuning of the crystal might be facilitated, comprises the steps of mounting the crystal by aluminium wires in a tantalum frame which is then fixed in a further mounting means, such as a semi-conductor header i.e. that portion of the encapsulation which comprises the lead wires and their anchorage, and finally removing portions of the Ta frame to insulate the Al electrodes from each other. The crystal is attached to the frame by Al wires extending from opposite corners to upstanding lands on the frame, the crystal and frame being supported on a jig. The crystal and frame are then inverted and turned through a right angle. Two more leads extending from the remaining corners of the crystal are then attached. The crystal frame is mounted in the header by resistance-welding the lead wires to Ta extension pieces T which are themselves resistance welded to the Ta frame. The crystal is tuned by anodically oxidizing the Al and Ta simultaneously by immersion of the assembly in an electrolyte, the extension pieces T being such as to prevent the lead wires contacting the electrolyte. The electrolyte may comprise saturated boric acid solution adjusted by means of ammonia to a pH of about 8.

Title: Improvements in self-regulating pumps in particular for the injection of fuel into internal combustion engines
IPC: F02M59/36
Filed: 1958-12-18
Abstract: 896,701. Fuel injection pumps. BESSIERE, P. E. Dec. 18, 1958 [Dec. 24, 1957], No. 40929/58. Class 102(1). A fuel injection pump comprises a main piston 1 reciprocating in a cylinder 3 provided with an inlet 4, an outlet 5 and a by-pass conduit 7. The by-pass conduit 7 is controlled by a slide valve 8, loaded to the closed position by a spring 9 and actuated hydraulically by liquid delivered by a piston 11 which reciprocates in synchronism with the main piston 1. On the delivery stroke of piston 11, liquid first passes through a conduit 27 to close a slide valve 30 and then flows past a non-return valve 15 to act on the end of the slide valve 8. This pressure acting on the end of the slide valve is controlled by the flow through a conduit 17 and a restricted outlet 21 formed by a groove 19 in the slide valve. The pistons 1, 11 are reciprocated at engine speed and for low speeds, the pressure acting on the end of the slide valve is not sufficient to move this valve against the spring loading and the maximum amount of fuel is delivered. When the speed of the engine is such that the pressure acting on the end of the slide valve 8 starts to move the valve upwards, this upward movement reduces the constriction 21 which further increases the pressure on the end of the slide valve. When the constriction 21 is closed, the slide valve moves quickly to open the by-pass conduit 7 practically simultaneously with the closing of this restriction, and a second groove 23 then opens the conduit 17 sufficiently to maintain the valve in its upper position. The return movement of the valve 8 is controld by flow through the open valve 30 and a throttle 31, preferably adjusted by a speed governor. This brakes the return movement of the slide valve so that, for engine speeds above a predetermined value, the slide valve does not complete its return stroke before being again actuated by the delivery of the piston 11. The spring loading may be adjusted by a screw 10 and the lower position of the valve, and hence the initial value of the constriction 21, by a screw abutment 22.

Filed: 1975-10-09
Abstract: 1502844 Metal oxide gas sensors MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 9 Oct 1975 [11 Oct 1974 (2) 29 Oct 1974] 41485/75 Heading G1N A metal oxide reducing gas sensor is composed mainly of 7-ferric oxide. In one form of sensor a mixture of γ-ferric oxide powder and water is applied as a thin film to the outer surface of a tube of forsterite to bridge a pair of gold electrodes deposited thereon and the film is then fired at a temperature of 350‹-600‹C for a time of 30 mins to 5 hours in an oxidizing atmosphere. A platinum heater element is wound inside the tube. In an alternative form a mixture of lepidocrocite powder (γ-FeOOH) and water is applied as a thin film to one face of an alumina plate to bridge interdigited gold electrodes thereon, a platinum heater foil being affixed to the opposite face of the plate. The film is then fired at a temperature of 150-600‹C for 30 mins to 5 hours in an oxidizing atmosphere. Instead of using γ-FeOOH a slurry of magnetite, Fe 3 O 4 , with water is applied to the plate and fired at a temperature of 100‹- 600‹C for 30 mins to 5 hours. Alternatively a mixture of α-ferric oxide powder in polyvinyl alcohol is applied as a thin film to the plate, prefired at a temperature of 700‹ to 1300‹C for 1 to 10 hours in oxygen, fired at 200‹ to 450‹C for 15 mins to 3 hours in hydrogen saturated with water vapour to form magnetite and the magnetite is then fired at a temperature of 100‹ to 600‹C for 1 to 5 hours in air to form sintered γ-ferric oxide. In a further embodiment magnetite powder is moulded to form a flat plate which is prefired at a temperature of 600‹ to 1100‹C for 30 mins to 10 hours in a non-oxidizing atmosphere. The resultant plate is then fired at a temperature of 100‹ to 600‹C in an oxidizing atmosphere for 30 mins to 5 hours and interdigited gold electrodes vacuum deposited on one surface and a heater coil mounted adjacent the plate. In a similar embodiment α-ferric oxide is moulded to form a plate which is prefired at a temperature of 800‹ to 1000‹C in an oxidizing atmosphere for 1 to 3 hours and the sintered plate then fired at a temperature between 200‹ and 450‹C for 10 mins to 2 hours in H 2  saturated with water vapour after a pair of interdigited silver electrodes had been deposited on one surface. The firing forms on the surface between the electrodes a layer of magnetite which is converted to γ-ferric oxide by further firing at a temperature of 100‹ to 600‹C for 30 mins to 3 hours in an oxidizing atmosphere. A platinum foil heater is affixed to the opposite face of the plate.

Title: Integrated navigation systems for ships
IPC: G08G3/00
Filed: 1971-08-20
Abstract: 1359298 Radio navigation ESSO RESEARCH & ENG CO 20 Aug 1971 [1 Sept 1970] 41715/70 Heading H4D A shipborne navigation system has a number of sensors giving position information and computer means for determining the best estimate of position by considering appropriate sensors. The system determines the error in the estimated position from a knowledge of the sensor accuracies and decides if the error is acceptable for the general area in which the vessel is located, e.g. a greater accuracy is preferred if the vessel is in coastal waters than oceanic. In addition the system decides if the error is acceptable for the vessel to proceed to the next area of the voyage. The system utilizes a computer performing the algorithm of Fig. 1. The availability of sensors is determined by the vessel's position, e.g. the oceanic sensors may not be suitable or available for coastal areas. The computer decides at 3 which of the available sensors is most accurate and reads the output. At 5 the availability of other comparably accurate sensors is determined. If there are any available then the most accurate one is read at 7. This process continues until no more comparably accurate sensors are available, in which case the readings are combined at 9 and the vessel's position given an initial estimate at 11. However, the initial estimate may indicate that one of the sensors is unsuitable for the vessel's general area, e.g. if in coastal waters and an oceanic sensor is giving an output. If so, that sensor is discounted at 15 and the whole process repeated from 5. Eventually, all such spurious sensors are discounted and the output from each used sensor compared at 17 to the combined or averaged outputs at 11. If the output of any sensor is seriously different from the output at 11 then that sensor is in error, a warning is given at 18 and the sensor discarded. The whole process is repeated until all erroneous sensors are discarded and the output at 11 gives the best estimated position. From a knowledge of the accuracies of the used sensors the error E 0  in position is determined at 19. The output from 11 is used at 21 to determine the present phase P 1  of the voyage, i.e. the vessel's general area. The error E 1  in position acceptable in phase P 1  is determined at 23 and at 25 it is decided if E 0 >E 1 . If so, then an alarm is given at 27 indicating that the vessel's position is not known to sufficient accuracy. In addition, the error in position is displayed. If E 0  < E 1  then the course to be made good is calculated at 28. The next phase P 2  of the voyage is determined at 29 and the error E Z  allowable in P 2  determined at 31. If E 0  > E 2  it is not safe to proceed to P 2  and a warning is given at 35. If E 0  < E 2  then the algorithm finishes at 37.

[Also in Division B5] Flat workpieces, such as tubing of plastic material which are to be made into bags, are each fed from a cutter 5 in a longitudinal direction to a stop 3, and then fed to the right in a transverse direction to a processing apparatus, the workpiece in the stopped position being grasped and moved into a lower plane in the transverse direction, so that the following workpiece can be moved towards the stop 3 before the previous workpiece has left the stopped position. Each workpiece on leaving the cutter 5 is fed by five pairs of belts 6 on to three belts 7, which support the left part of the workpiece, and the right edge of the latter is supported on a ledge in a guide member 8. The workpiece is moved by the belts 7 and presser rollers 22 over a feed table 29 up to the stop 3. The table 29 is narrow and slotted to receive a slidable extension 25 which is combined with a sloping flange 26 and a U-shaped element 24 secured to bearing blocks 11, 12 supporting the guide member 8: the blocks 11, 12 are adjustable transversely by screw means, operated by a hand wheel 16, so that the guide 8 and table extension 25 can be adjusted to suit different widths of workpieces. The guide 8 comprises a rotatable member having four arms in the form of a cross to provide four ledges for supporting workpieces in turn, and the end of each ledge carries sets of rollers 23 which are arranged so that they are spaced from, but immediately above one of the other ledges, thus providing four recesses 9 for the workpieces. As the guide 8 is rotated, the edge of the workpiece is lowered, and the rollers 23 press it on to continuously-driven belts 33 which feed the workpiece between a pair of further feed belts 34, 35 for conveyance to the processing apparatus. Fig. 4 shows a workpiece 2a partly overlying the table extension 25 and the flange 26 during removal, and the next workpiece 2b in position over the table 29 against the stop 3, with its edge supported on the next ledge of the guide 8. Rotation of the guide 8 through a right-angle is effected by a power-driven shaft 19 through bevel gears 20, 21 in any transverse position of the guide 8, and power is supplied when a workpiece contacts a switch 18 arranged on the stop 3. In a modification, the guide 8 is replaced by a guide 40 (Fig. 5, not shown) of Z-shaped form which is rotated through 180 degrees to press the workpiece on to the feed belts 33. The edge of the workpiece extends beyond the rotary axis of the guide, so that the workpiece is pushed back and aligned during the rotation of the guide.
