Patent GB-622493-A (GB)
Title: Improvements in and relating to gauges
IPC: G01B13/00
Filed: 1946-10-03
Abstract: 622,493. Gauging-apparatus; Bourdon gauges; indicating-apparatus. RUPLEY, F. L. Oct. 3, 1946, No. 29533. [Classes 106 (ii) and 106 (iv)] [Also in Group XXIX] Fluid-pressure gauging-apparatus comprises a gauge head, having a port variable by the size of the work-piece to be measured, communicating through conduit means with a fixed discharge orifice in a Bourdon or like tube which forms a byepass in the conduit means, this tube actuating a pointer of a measuring instrument to indicate variations in the effective outlet area of the port in the gauge head. Fluid, such as compressed air, is conveyed through an adjustable regulator 43, a conduit 44, and a T-shaped member 45 to a pressure gauge 49 and a restricting device 47. The device 47 comprises two passages 51, 53 arranged in series having fitted therein cupshaped members each with an orifice whereby moisture and dirt are removed from the air by a series of expansions, and the pressure and temperature rendered substantially uniform. The air then passes through a pipe 61 to a cupshaped fitting 62 to which a Bourdon gauge 80 and a gauge head 69 are connected. The gauge head has a tubular shank 68 secured in a fluid-tight manner within the fitting 62, and the air passes down the bore 70 in the head and discharges radially through a port 71 in a fitting 72. Disposed opposite the port 71 is a feeler button 73, adapted to move towards the port during gauging operations, mounted on a leaf spring 74 secured to the head 69. During internal gauging the air discharged from the port 71 escapes along axial and circumferential channels in the head 69. The indicating gauge 80 comprises a Bourdon tube 83, the free end of which is connected by a drag link 84 with a gear sector meshing with a pinion on the shaft of the pointer 88. The pointer moves over a dial 89 on which there is a resilient zero stop comprising a spring. A fixed port 91 is located in the Bourdon tube 83 to provide a continuous bleeding-off of air from the gauge so that, even when the gauge port 71 is completely closed, the pointer 88 will only rise to a predetermined maximum point, which point may be used for checking the accuracy of the gauge instead of using an auxiliary master gauge.

Title: Coin testing apparatus
IPC: G07D5/00
Filed: 1970-06-18
Abstract: 1319490 Coin tester NATIONAL REJECTORS Inc GmbH 18 June 1970 [10 July 1969] 29551/70 Heading G4V A coin tester for a vending machine is arranged to accept two coin types, e.g. silver and cupronickel, of equal currency value but with widely different electrical conductivities, and to reject all other coins or slugs. An inserted coin is checked for weight and minimum diameter by a balance 1. Annuli and large diameter coins are respectively held up by a feeler 6 and lever 4. After rolling down a shoot 3, a thick coin is obstructed by a magnet 2, which also removes ferrous coins. The further path and speed of the falling coin is then affected by the magnetic field from the magnet 2. Low conductivity cupronickel coins are retarded little and bounce off the anvil 8, over a separator 7 into an acceptance shoot 11. Medium conductivity coins are further retarded to be deflected or not by a sheet 9 into a reject shoot 10. High conductivity silver coins are still further retarded to strike both the sheet 9 and anvil 8 and fall to the acceptance shoot 11. Even higher conductivity coins are greatly retarded to be deflected by the sheet 9 into the reject shoot 10. Any coins or slugs jamming within the tester are passed to the reject shoot 10 by a clearing lever (not further disclosed), the magnet 2 being cleared by a wiper 5.

Title: Improvements in or relating to methods of and means for packing commodities
IPC: B65B25/00
Filed: 1956-09-27
Abstract: 870,551. Container-forming and filling machines; packages. DOWNIE, G. Sept. 20, 1957 [Sept. 27, 1956], No. 29590/56. Class 94(1). In a machine for producing an article consisting of a solidified substance contained in a bag and mounted on a stick, e.g. a lollipop, a web 13 of heat-sealable material is fed from a roll 12 by rollers 14, 15 and passes through guides 19 and a slot 28 in a table 26. Knives 16, 17 sever a portion 18 from the web and a recessed plate 20 is moved to the right Fig. 2 over the table to remove four sticks from stacks 22 contained in magazines 21 and fold the portion 18 about the sticks. A heated plate 29 is lowered to unite the folds over areas 33, thus forming four pockets, and secure the stick to the mouths of the pockets at 34. The pockets are then conveyed to the left, Fig. 1, by endless chains 41 projecting through slots in the table 26, and lifted from the table by cam-operated grippers 80 which engage the ends of the sticks. The grippers are carried by bars 47 pivoted at their ends to the links of endless chains 45, 46 passing over verticallyspaced sprockets 43 and 44, the latter being driven intermittently. The pockets are first raised to station D, where pivoted knives 51 are swung downwardly to cut away the shaded areas 33, thus partially separating the pockets, and then to station E where the pockets are opened by blasts of air delivered through nozzles 56 and filled with measured quantities of liquid from reservoirs 58 supplied by a pipe 59. The flow from the reservoirs is controlled by valves operated by linkage 57, 61. At the next station F, the mouths of the pockets are heat sealed by pivoted heaters 63 which are swung downwardly by linkage 67, 68 into co-operating relationship with a fixed bar 69, and the completed packages and then conveyed through station G for freezing or other treatment. The pockets may be formed from two webs instead of a folded web and opened by suckers or plungers instead of air blasts. If the solidified substance is subsequently to be consumed as a beverage, the sticks may be hollow so as to serve as drinking straws and the pockets may be closed and sealed in planes at right angles to their bases, see Figs. 3-7 (not shown).

Title: Fuel feed control device for internal combustion engine
IPC: F02D41/20
Filed: 1973-02-07
Abstract: 1428353 I C engine fuel injectors HITACHI Ltd 7 Feb 1973 Divided out of 1427995 29696/75 Heading F1B [Also in Division H3]  The opening and closing times of an I.C. engine fuel injection valve which is opened by an electromagnetic coil are reduced by an arrangement comprising first control means for applying a voltage to one side of the coil when the valve is to be opened and second control means for applying the voltage to the other side of the coil when the valve is to be closed; third control means arranged to connect the other side of the coil to earth while the voltage is being applied to the one side so as to pass a current through the coil which is only sufficient to hold the valve open; fourth control means also arranged to connect the other side of the coil to earth, for a predetermined period, while the voltage is applied to the one side, so as to pass a current sufficient to open the valve; and fifth control means arranged to connect the one side of the coil to earth when the voltage is applied to the other side, so as to close the valve. Prior to opening of the valve, its solenoid winding 2 is energized via control transistors 5B and SE and a resistor 3, the resistor limiting the current to a value which is insufficient to open the valve but would be sufficient to hold the valve open if it were already open. When the valve is to be opened, a control pulse is applied to a transistor 5A to increase the current temporarily to a value which effects opening of the valve. Thereafter, the valve is held open by the current supplied via the transistors 5E and 5B. When the valve is to be closed, transistors 5E and 5B are turned off and at the same time transistors 5C and 5D are turned on briefly to provide a reverse voltage to assist the rapid collapse of the magnetic flux.

Filed: 1957-09-23
Abstract: 851,867. Moulding diffusing plates for electric lighting fittings &c. GENERAL ELECTRIC CO. Ltd. Aug. 22, 1958 [Sept.23, 1957], No. 29834/57. Class 87(2). [Also in Groups X, XV, XVI, XXII and XXIII] A surface is figured with a regular pattern of closely spaced octagonal pyramids by cutting on it first and second sets of equally-spaced parallel grooves, the two sets being perpendicular, cutting a third set of parallel grooves in pairs, the apex lines of the two grooves of each pair being equally spaced about a different one of the parallel lines containing the first diagonals of alternate rectangles in the rows of commonsided rectangles into which the surface is divided by the apex lines of the first two sets, and cutting a fourth set of parallel grooves in pairs, the apex lines of the two grooves of each pair being equally spaced about a different one of the parallel lines containing the second diagonals of the same set of alternate rectangles. the grooves all being of substantially V-shaped cross-section and of a width and spacing such as to form the pyramids. The grooves may have plane or concave or convex curved sides, and the point of the V may be rounded or flattened. The spacing between the grooves may be chosen to produce pointed or truncated octagonal pyramids. The surface may be formed on a plane steel plate which is used as a die to impress the complementary configuration on a synthetic resin or glass sheet. Alternatively, the figured surface may be used to produce a die of complementary configuration, e.g. by forming the figured surface on a plastic, plate, treating with graphite electroplating with chromium, stripping the electroplated layer, and backing with a further metal layer. As shown in Fig. 3, a steel die-plate having regularly spaced octagonal pyramidal projections is prepared by cutting a first set of equally-spaced parallel grooves with their apex lines 3a, 3b, 3c &c. at distances d apart. A similar second set of grooves is formed at right angles to the first set with apex lines 4a, 45, 4c &c. A third set of grooves is cut in pairs with apex lines 7a, 8a, 7b, 8b, 7c, 8c &c. on opposite sides of diagonals such as 6 passing through alternate rectangles formed by the apex lines of the first two sets of grooves and each at a distance ¢ (#2-1) d from such diagonal. A fourth set of pairs of grooves 9a, 10a, 9b, 10b, &c. is similarly cut parallel to the other diagonals, such as 11, of the same set of alternate rectangles. The die-plate may be used to manufacture a transparent diffusing plate having corresponding pyramidal depressions from polymerized methyl methacrylate. The angle of the V-shaped groove is preferably between 90 and 150 degrees the range of 105 to 130 degrees being particularly suitable. Specification 851,217 is referred to.

Abstract: 796,474. Stopping shafts in predetermined positions. COLLINS RADIO CO. Oct. 2, 1956 [Dec. 6, 1955], No. 30017/56. Class 80 (2). A shaft 9 which may be stopped in any one of a number of predetermined positions carries freely a continuously rotating gear 10 meshed by a driving gear 11 rotated by a motor, and also carries a stop disc 7 rotationally fast therewith and formed with a number of radial slots around its periphery for engagement by a pawl 5 pivoted on a fixed base 3. The pawl 5 is normally biased by a spring 14 to engage one of the radial slots in the stop disc 7, but energization of a solenoid 4 overcomes the bias of the spring to disengage the pawl from the stop disc, and engage it in one of a number of radial slots in an intermediate clutch disc 8 carrying balls 15 engaging frictionally at each side with the continuously rotating gear 10 and the stop disc 7, respectively. The stop disc 7 and the shaft 9 are thereby driven until the solenoid 4 is de-energized, so that the spring 14 is allowed to disengage the pawl 5 from the clutch disc 8 and re-engage it with one of the slots in the stop disc 7, to hold the shaft in a new position. The clutch disc 8 and balls 15 now rotate idly until the solenoid 4 is re-energized. Specification 660,939, [Group XXXVIII], is referred to.

Abstract: 800,434. Electric battery lamps. SONG & CO., Ltd., V. K. Oct. 15, 1956 [Oct. 20 1955], No. 30043/55. Class 39(2) [Also in Group XXXVII] A switch unit for attachment to the casing of a torch or battery lamp comprises a switch box or body 2 made of aluminium, aluminium alloy, or like soft metal, a slide 3 mounted on the box or body 2 and slidable longitudinally thereof, and a resilient member or slide spring 4 carried on the underside of the slide 3 and provided with a dimple 4a adapted to engage with at least one rounded projection 8a formed on the surface of a strip 8 of harder material secured to the relatively soft metal of the switch box or body, thereby obviating the wear that would otherwise result from the projection 4a engaging the aluminium surface of the switch box 2. As shown, an aluminium switch box 2 secured at one end to a torch case 1 by a tongue 2a engaging within a slot in the box, and at the other end by a rivet 10, carries a switch slide 3 also made of aluminium. The slide 3 is held to the box 2 by legs 3a, Fig. 3, which extend through longitudinal slots in the top of the box and also engage within smaller slits in a movable contactor strip 7 which can thus be moved longitudinally with the slide 3. A bridge strip 8 of a metal that is harder than aluminium, e.g. brass or steel, is fixedly secured to the switch box 2 by passing its edges through slots in the box and bending them inwardly, and the strip 8 and the part of the box 2 beneath it are pressed to form two dimples 8a, this being effected prior to the attachment of the slide 3. As shown, the slide 3 is in the "off" position. Movement of the slide to the right, so that the dimple 4a on the spring 4 is located between the two dimples 8a, places the switch in the "flash" position whereat depression of a flashing-button 9 brings the adjacent end of the movable contactor 7 into contact with the part 5a of a stationary contact strip 5 connected in the bulb circuit. Further movement of the switch slide to the right brings it into the "on" position, with the contactor 7 in contact with the portion 5b of the strip 5. Movement of the switch slide to the different positions is indicated by an accompanying clicking sound. A thin fibre sheet may be located between the slide 3 and the switch box 2 to prevent scratching of the latter. In a modification, the flashing arrangement is dispensed with and the bridge strip 8 has only one dimple 8a, which provides a click when the slide is moved between "on" and "off" positions. Alternatively, the movable contactor 7 and the stationary contact strip 5 may be replaced by a single strip which is movable longitudinally into contact with the reflector for the "on" position.
