Title: Improved apparatus and method for crystal growth
IPC: B01D9/00
Filed: 1929-04-18
Abstract: 333,598. Imperial Chemical Industries, Ltd., and Cocksedge, H. E. April 18,1929. Crystallizing. - Substances are crystallized in a vessel 1 having a vertical annular partition 2, by circulating a solution of the substance down the centre of the vessel and up through the annular space by means of a propeller 3, crystals which have grown to the desired size being removed by means of the elutriating tube 5 attached to the bottom of the vessel. The bottom of the vessel is curved to assist the flow. Air or gas may be introduced, as at 4, to increase the circulation, or for cooling or for chemical reaction. The crystallization is controlled by withdrawing through a sieve 8 a portion of the liquid destroying any crystal nuclei therein, if desired, by addition of water or by re-heating in a vessel 9, and then recirculating the liquid by a pump 10 through a saturator 6 up the elutriating tube 5. In the -saturator a controlled number of crystal nuclei may be introduced or formed by cooling. Large crystals are removed in known manner from the bottom 7 of the elutriator. In an example, uniform 3 mm. crystals of sodium carbonate monohydrate were obtained in a vessel 12in. diam. with an annular partition 9in. diam. and an elutriating tube of ¢ in. diam. The rate of flow was of the order of 3in. per sec.

Abstract: 1500433 Adjusting and testing fuel injection pumps ROBERT BOSCH GmbH 26 March 1975 [1 April 1974] 12546/75 Heading F1A The delivery quantity of an in-line fuel injection pump 10 is adjusted during the final assembly thereof by an arrangement comprising a delivery quantity measuring device 84 for measuring and indicating the quantity of fuel delivered from a given cylinder, and adjusting tool 28 movable to cause angular adjustment of the cylinder's liner and thereby adjust the quantity delivered, an adjusting motor 53 for driving the tool 28, and a control device 54 for controlling the motor 53. In the embodiment shown each pump cylinder liner is adjustable by an individual adjusting tool 28 driven by a respective motor 53, but alternatively a single adjusting tool 28 movable to different locations may be used to adjust the cylinder liners in turn. Each adjusting tool 28 is in the form of a lever having at one end a projection 30 received in a groove 31 in flange 32 on a respective cylinder liner. The opposite end of each adjusting tool lever 28 has a groove 46 in which is received a worm 48 on a respective worm-wheel 49. The worm-wheels 49 are rotatably supported on a shaft 55 and are driven by their adjusting motors 53 through chains 51 connecting gears 52 on the motor to gears 50 on the worm-wheels 49. To allow the fuel injection pump and a carrier 11 therefore to be accurately located in a clamping device 12, without interference from the tools 28; the shaft 55, motors 53  and tools 28 are mounted between bearing plates 25 pivotable on a shaft 18. After clamping of the pump, a piston and cylinder motor 19, 20 is actuated to cause the worms 48 to engage the grooves 46. In the clamped position the cam shaft 40 of the pump is connected through a clutch 63 to a drive unit 62. The control device 54 has a manual control 89 or an automatic control in the form of a process computer 80 fed with signals from a tachogenerator 70, the quantity measuring device 84 and the pump's quantity regulating control rack 78. These signals are compared with desired values supplied to the computer by an input device 81 controlled by punched cards. Signals dependent on the difference between the actual and desired delivery quantities for the speed and rack position selected are sent to the control device 54, the latter operating to cause each motor 53 to rotate by the exact amount necessary to achieve the required delivery. Bolts 35 holding the flanges 32 in position are initially tightened by an amount which allows adjustment of the flanges, whereafter they are fully tightened by a screwing device 90.

Title: Card reader
IPC: G06K7/016
Filed: 1975-03-26
Abstract: 1510342 Card reader INCOTERM CORP 26 March 1975 [28 March 1974 (2)] 12566/75 Heading G4M A reader for a card carrying binary data in a matrix of M rows by N columns has guides 128, 129 directing the card in a first direction, a row of sensors 134 extending in the first direction and an array of sensors having at least two rows 132A-132D and N columns extending at right angles to the first direction. The number of sensors in the row 134 multiplied by the number of rows of sensors 132 is equal to M and the spacing between the rows 132 is equal to the spacing between the rows on the card multiplied by the number of sensors in row 134. As shown for an 80 x 12 card there are twenty sensors in row 134 and four rows of sensors 132. The presence of a card is detected when the leading edge of a card passes the left hand sensor of row M+40 and a sensor 138 determines if the card has been inserted correctly. If the insertion is correct when the Group 1 sensor is observed by the card leading edge the sensors in rows 132A-132D are sampled in parallel and the data read is stored. As each sensor in row 134 is observed the sensors 132 are sampled and the data passes through a Multiplexer 158 to a Memory 152 addressed by a Scan Control Unit 162. The Scan Control increments a Counter 156 to determine which lines of the card are to be read and when the appropriate Group Sensor is obscured the appropriate rows are read.

Title: Improvements relating to spring motors
IPC: F03G1/00
Filed: 1923-05-11
Abstract: 219,427. McGregor, A. May 11, 1923. Spring power-storing mechanism. - A spring motor is provided with variable transmission gearing comprising a friction or toothed member driven by the driving-shaft, an intermediate friction or toothed wheel adapted to slide across the first member, and a third friction or toothed member driven thereby. Also the winding-crank is automatically declutched from the spring shaft after a predetermined number of revolutions of the latter. The main shaft 15, Figs. 1 and 3, is driven from spring drums 3 through multiplying gearing 6, 6<a>, 7, 7<a>, friction discs 8, 10, 11<a> and reducing gearing 12, 12<a> - - 14. The disc 10 is carried in a bracket 17 upon a spring- controlled, vertically-slidable rod 18. An arm 24, fixed to the rod 18, is maintained in engagement with one arm of a bent lever 25 pivotally mounted on a bracket 26, the other end of said lever engaging a collar 27<a> on one member 27 of a composite sleeve 27, 27<b>, Fig. 5, the two parts of which rotate together but can move axially independently. During winding, a pin wheel 33 on the winding-shaft 4 rotates the member 27b, the other sleeve-member 27 being displaced along the screw 28, to the left, Fig. 1, until a cone 38 causes a pawl 34 to contact with an arm 37a on a coil-clutch 37, 39, thus preventing its engagement and any over-winding. The movement of the member 27 also moves the lever 25 to raise the rod 18 and friction disc 10. As the spring unwinds, the member 27 moves to the right, Fig. 1, and the disc 10 moves forward the centre of the disc 8, thus increasing the unwinding movement of the spring necessary to maintain constant speed as the energy available per revolution decreases. A governor-brake 11<b>, 11<c> is provided on the shaft 11. The movement of the member 27 also releases the clutch 37, 39 for re-winding. In a modification, a positive drive is provided by means of a toothed disc 108, Fig. 6, a pinion 110, and a toothed drum 112. The disc is formed of a number of concentric rings each provided with radial teeth of the same pitch as those on the pinion 110. A composite sleeve 118, 119 on a threaded shaft 117 actuates the system of levers 125, 128, 129 and, as the motor springs run down, the lever 129 is caused to traverse the pinion 110 from ring to ring across the disc 108, the wheel 110 being carried by a sleeve 111<a>. In a further modification, two friction or toothed discs 208, 214, Fig. 10, are provided coacting with a pinion 213, the disc 214 being secured to a sleeve 227 mounted to move axially on the driven shaft 228 and connected thereto by a spring 231. The force required to coil the spring 231 further is equal to that required to drive the driven mechanism. An excess of driving force from the motor springs causes the sleeve 227 to rotate on the shaft 228 and the disc 214 to move away from the pinion 213, thereby causing the latter to slip. The motion of the pinion 213 across the disc 208 is controlled by the ratchet 205 and noacting pawl 215, and the levers 216, 222, 226.
