Title: A device for measuring the displacement of a part of a machine for example a lathe, cylinder grinding machine, or the like machine
Inventor: GUSTAVSSON LARS ERIK HERBERT
IPC: B23Q17/22
Filed: 1949-11-30
Abstract: 680,825. Grinding-machine details. AKTIEBOLAG ESSESS. Nov. 30, 1949, No. 30727/49. Class 60. [Also in Groups XIX, XXII and XXXV] A device for measuring the displacement of a part of a machine, e.g. a lathe or a cylinder grinding machine, comprises a pair of rollers 21, 22 mounted on the displaceable part or on a fixed part of the machine and adapted to grip between them a band 17 secured between two fixed points on the machine or to the displaceable part respectively, so that an indicator connected through a transmission means to the roller 22 is caused to register the distance said roller rolls along the band or the displacement of the band if this is moved. In the embodiment illustrated, the device is mounted on the displaceable part by means of lugs 11 and indicates the extent of displacement with fingers 14, 14a on a graduated dial 13. Flanged rollers 23, Fig. 4, mounted in a carrier 24<SP>1</SP> for the roller 22, guide the band 17 between the rollers 21, 22 and out of contact with the roller 22. The roller 21 is mounted on a lever 34 hinged at 35 to the carrier and retained against the compression of a spring 36 by a toggle linkage 39, 40 in which the links 40 are pivoted at 41 and engage a pin in the end of link 39. A further link 43 connects the links 40 to a bellcrank lever 42<SP>1</SP>, Fig. 2, attached to the armature 45 of an electromagnet 46 adapted, upon energisation, to rock the lever 42<SP>1</SP> against a spring 47 secured thereto and so upset the toggle linkage and allow the spring 36 to grip the band 17 between the rollers 21, 22. Upon being upset, the link 40 engages a lever 48, Fig. 4, which rotates its shaft 49 and causes a catch 57, Fig. 6, mounted thereon to release a locking plate 53 carried by a spindle 24 secured to the roller 22. The spindle 24 transmits rotation of the roller 22 through gearing 25, 26, 28, 31, 29, 32, Fig. 2, to a spindle 30 carrying the finger 14a and to a hollow, spindle 33 supporting the finger 14. Back-lash is taken up in the gear train by a uni-direction induction motor 55 (see Group XXXV) which also returns the fingers when the electromagnet is de-energised. The catch 57 is then caused by a spring 54 to relock the transmission. In alternative forms, back-lash may be taken up by a coiled spring slipping with constant friction on the spindle 30, and the electromagnet may be replaced by hydraulic or mechanical means.

Title: Improvements in or relating to a fluid control system for washing machines
IPC: D06F1/08
Filed: 1946-10-16
Abstract: 627,593. Washing-machines. DOLE VALVE CO. Oct. 16, 1946, No. 30783. Convention date, Nov. 13, 1945. [Class 138 (ii)] [Also in Group XXIX] A fluid-control system for a washing-machine comprises dual automatic temperature-control mixing valves 10, 11, Fig. 1, a delivery conduit 29, a pair of valves 24, 25 for controlling the supply of fluid from the mixing valves 10, 11 to the conduit 29, manual means for opening the valves 10, 11 and a pair of fluid-level responsive members for shutting the valves 10, 11. The delivery pipes 26, 27 from the valves 24, 25 lead to the delivery conduit 29 which has interposed in it a device for providing a constant rate of flow comprising an apertured resilient diaphragm 31 seated upon a shouldered member 32. The valves 24, 25 are of the same general construction as the valve 19 described in Specification 621,587, the flow through each valve being controlled by a pilot 50, Fig. 2, through a spring-pressed bell-crank lever 55 by a cup-shaped member 59 on a slidable shaft 60. A spring-pressed ball 64 in the bearing 62 of the shaft 60 is adapted to engage either of two annular recesses 65, 66 in the shaft. When the shaft 60 is pushed inwardly the member 59 actuates the bell-crank lever 55 so as to open the valve. The valve is closed by the action of a cup member 70 pivoted on an arm 71 which is pivotally mounted on the valve structure and normally biassed to its upper position by a spring 73. When sufficient fluid is in the washing tub, the cup member 70, which is connected by a hose 74 with the tub, receives sufficient fluid to weigh down the arm 71 and cause an extension 76 thereof to retract the shaft ; the member 59 is then retracted so that the bell-crank lever 55 moves to close the valve. The valve may also be closed by rotating the shaft 60 so that a slot 68 in the member 59 registers with the upper end of the bell-crank lever 55 to permit the latter to move to the extent necessary to close the valve. In an alternative arrangement, (Fig. 4, not shown), each delivery valve 24, 25 is controlled by a solenoid which is energized by a push button to open the valve and de-energized by the fluid-level operated member which is of the float type. If desired, a constant flow device may be placed between each of the mixing valves 10 and the corresponding delivery valve 24, 25.

Title: Process for the isolation of hydrofluoric acid from reaction gases
IPC: C01B7/19
Filed: 1963-08-06
Abstract: <PICT:1056077/C1/1> In a process for purifying hydrofluoric acid, gases containing it and, for example, SiF4, SO2, CO2, H2O and solids are washed free of solids in washer 3 with liquid from the sump 2 of column 1.  At the same time a major proportion of high boiling components are removed by condensation, and the gases are then contacted in column 1 in counter-current with liquid condensed in condenser 7.  Residual high boiling components and part of the HF are condensed and transferred via pipe 14 and heat exchanger 13 by means of pump 12 to column 11.  Residual HF-containing gases from column 1 pass to absorption plant 8, where the HF is freed of low boiling components by being absorbed in sulphuric acid, which may be that used in the HF-producing reaction.  The absorbed HF is passed via pipe 10 to column 11 which preferably operates under pressure, e.g. by introducing air or other inert gas to the top of the column or condenser 17.  The HF, freed of high boiling components in column 11, is condensed in condenser 17 and collected. Liquid collecting in sump 15 is returned to column 1 via pipe 16 and heat exchanger 13, and any HF not condensed in condenser 17 passes to absorber 8.

Abstract: 537,118. Directive wireless systems. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE. Dec. 6, 1939, No. 31640. Convention date, Dec. 6, 1938. [Class 40 (v)] Signals from two crossed frame aerials R1, R2, Fig. 7, are combined with those from a non- directional aerial H through a reversing switch U1 so that the two frames are coupled successively and with alternating polarity to the receiver E, whilst the output from the receiver is applied through a switch U2, operating synchronously with the switch U1, to two indicator coils A1, A2, also set at right-angles to each other, so that, when one of the two aerials R1 or R2 is connected to the receiver input, the corresponding indicator coil A1, or A2 is connected to the output with like polarity. Fig. 8 shows the working sequence of the input and output switches U1, U2; the polarity of the frame R1 is first kept in step with that of the winding A1, and similarly that of the frame R2 and winding A2, at the next movement of the switch and so on. In Fig. 10 the input switch U1 comprises four salient magnetic poles, two of which c, d are coupled to the frame aerials .and two e, f to the receiver E. The rotating core g is partly screened as shown, so that first the flux in pole c induced by the aerial R2 is transferred through the pole f to the receiver E, and next the flux induced by the aerial R1 is similarly coupled to the receiver through the poles e and f. The output switch U2 consists of a brush rotating over commutator segments connected to the two indicator coils A1, A2. The coils A1, A2 may operate a pair of astatic needles located either inside or outside a magnetic core (Fig. 13 to 16 not shown). The direction-finder described may be used in combination with a " homing " indicator, the windings of the two instruments being connected in opposition ; this will indicate any deviation from the course with great accuracy and sensitivity.
