Abstract: 422,222. Overhead travellers; pulleyhoists. SPENCE, W. L., 35, Kenilworth Road, Leamington, Warwickshire. Aug. 8, 1933, No. 22152. [Classes 78 (iv) and 78 (v)] [See also Groups XXXI and XXXII] A rope &c., lifting gear comprises two winding-drums 1, 13, geared together by mechanism contained in a gear-box 14, and a six-fall pulley block. The rope 2 from the drum 1 passes round a pulley 3 on the block, up over a pulley 5 on the drum shaft, down round an equalizing pulley on the block, and over a second pulley 9 on the drum shaft, finally reaching the drum 13 by way of a third pulley 11 on the block. The arrangement gives four falls on one side of the pulleys 5, 9, and two falls on the other side, necessitating off-setting the load hook to one side of the block centre. The pulleys 5, 9 are preferably mounted on rollers &c., running round the bearing housings of the drum shaft. Traversing means for the lifting-gear comprises a track 21 surrounded by an endless roller chain driven by a sprocket wheel 22 on a motor-driven shaft 23. The rollers of the chain are enlarged to run on a girder flange 19. The track 21 is attached to suspension links surrounding the drum shaft between the drum 1 and pulley 5 and drum 13 and pulley 9 respectively. Specifications 193,245 and 320,089, [both in Class 78 (v)], are referred to.

Abstract: 517,441. Engine valves and valve gear. O'SHEI, W. E., and TRICO-FOLBERTH, Ltd. July 27, 1938, No. 22390. [Class 122 (ii)] In reversing gear for the motors of wind screen wipers the cylinder houses spaced pistons 2 connected by a rack member 3 which oscillates the wiper shaft 6. Simultaneously - operated valves 7, 8 are connected by a cross-piece 10 to a piston-operated tappet rod 16. The valve 7 alternately parts the right and left-hand. passages in communication with the exhaust or a vacuum; the valve 8 alternately puts the passages into communication with a source of fluid pressure. The valve seatings are so arranged that the pressure of the operating fluid, or the suction, tends to hold the valves as set. The rod 16 enters an aperture 20 in. the cylinder head 9 and is enlarged and slotted to engage the pin 10. A spacing-ring 22 and a helical spring are arranged at one end of the rod. A head 17 and a spring at the end of the rod enter a hole 18 in the piston. The movement of the piston compresses the springs. When the valves are removed from their seats, the springs complete the movement. The. spacing-ring permits early valve operation. One or more rings may be used. Specification 255,054, [Class 122 (ii)], is referred to.

Title: Push rod type motion transmitting mechanisms
IPC: B60T13/18
Filed: 1971-04-19
Abstract: 1346469 Brake transmitting-mechanisms; fluid-pressure brakes AISIN SEIKI KK 19 April 1971 [20 Feb 1970 27 May 1970] 22504/71 Headings F2E and F2F A push-rod-type motion-transmitting mechanism for dual hydraulic brake systems comprises a main push rod 17 or 121, an intermediate motion-transmitting member 14 or 14<SP>1</SP> engaging one end of the main push rod, and a pair of auxiliary push rods 6, 7, parallel to and coplanar with the main push rod, (one on each side of it), the auxiliary push rods engaging respective rod-end-receiving surfaces 12, 13 or 12<SP>1</SP>, 13<SP>1</SP> formed on the side of the intermediate member opposite the main push rod and being kept in pressure contact therewith, each such surface being defined by a curve of gradually increasing curvature outwardly of the normal rod-end contact point, whereby force is transmitted axially from the main push rod to at least one of the auxiliary push rods if the intermediate member is inclined from its normal position. As shown in Fig. 1, the main push rod 17 connected at 21 to a brake pedal or equivalent engages a concave surface 19 of the intermediate member 14; motion is thereby transmitted to the auxiliary push rods 6, 7, which operate a brake force control mechanism 1. Each push rod 6 or 7 is maintained in contact with a generally concave surface 12, 12a or 13, 13a; each surface has a substantially plane portion 12a or 13a joined to a curved portion whose configuration is defined in the Specification. This configuration is such that if, during operation, the hydraulic circuit operated by, e.g. auxiliary push rod 7 through control mechanism 1 should fail, resulting in counterclockwise rotation of intermediate member 14 in its own plane, the part of surface portion 12 thereby making contact with the end of push rod 6 will transmit to the push rod a force acting along the axis of the rod. Any dangerous disengagement of the rod from the intermediate member, or initiation of lateral forces, is accordingly avoided. In mathematical terms, set out in the Specification, the axial distance between the contact point of rod 17 with member 14 and the contact point of rod 6 with member 14 when the intermediate member 14 has been rotated as above is a function of the normal axial distance between the contact points (the Fig. 1 position) the lateral distance between the axes of rods 6 and 17, b, Fig. 1, and the angle of rotation of member 14. The same applies to rod 7. In Figs. 6 and 7 the significant parts of surfaces 12<SP>1</SP>, 13<SP>1</SP> are defined by approximately involute curves to produce the same operational result.

Title: Apparatus for measuring the dimensions of objects
IPC: G01B11/04
Filed: 1970-05-11
Abstract: 1,246,949. Measuring length. TOKYO SHIBAURA ELECTRIC CO. Ltd. 11 May, 1970 [12 May, 1969], No. 22554/70. Heading G4H. In an apparatus for measuring the width of a steel sheet, the presence or absence of the sheet beneath the detecting head 27 is detected photo-electrically. Two detecting heads 27, 28, which operate in a similar manner, are scanned across the region in which the edges of the sheet are expected to lie, by pneumatic piston and cylinder assemblies 21, 23 and 24, 22. When the steel sheet does not lie below the detection head 27, the counter 57 records magnetic pulses generated by means of magnetic scale 38 and magnetic pick-up 29. The unit comprising parts 30, 39 and 58 operates in a similar manner. Pulse generator 64 feeds a count proportional to the separation of stops 49 and 50, into bidirectional counter 63. At the completion of the measuring operation, the counts recorded on counters 57 and 58 are fed into counter 63 and subtracted from the preset count, so that counter 63 displays a count proportional to the width of the steel sheet. This count may be fed on line 69 to a punch tape unit. The measuring process is controlled by control unit 51, when a signal is received on line 54 or alternatively when button 68 is depressed, to indicate the presence of a sheet beneath the measuring heads, and also when signals are received from stop units 49, 50 indicating that the pick-up heads 29 and 30 are adjacent to the stop units, a signal is produced on lines 55A, and 55B initiating the measurement. In an alternative embodiment the stop units 49, 50 are fixed so that they lie always above the steel sheet, i.e. at the opposite end of scales 38, 39 to which they are shown. The counts recorded on counters 57 and 58 are then proportional to the length scanned between the stop units 49, 50 and the edge of the steel plate, and these counts are added to the preset count in counter 63.

Abstract: 760,229. Transistor generating circuits. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Aug. 27, 1954 [Aug. 18, 1953], No. 22765/53. Class 40(6) In an oscillator, a tuned circuit L1 C1 is connected to the emitter of transitor TN diodes D1, D2 and D3 connecting the base to the tuned circuit, the base to one source of potential earth and the collector to a second source Vcc1, while resistors Rb, Rc and Re connect the electrodes to supply potentials Vbb1, Vcc2 and Vee respectively. A negative impedance characteristic is provided on its VE/IE characteristic, Fig. 4, the regions F-G-H and J-K being substantially independent of the transistor characteristics. From E to F the transistor is cut off at the emitter, diode D1 conducts, and the collector potential is determined by diode D3. As the emitter potential is increased from F to G, both diodes D1, D2 conduct until earth potential is reached whereupon diode D1 ceases to conduct. At point G the emitter starts to conduct, and when H is reached the base-collector current is sufficient for diode D2 to cease conduction and the negative resistance region HJ ensues. At point J all the electrodes are near Vcc1 and remain so until the diode D3 ceases to conduct at point K due to high collector current. The operation of the oscillator is determined by the regions F-G and J-K when the impedances are the sum of the forward impedances of diodes D1, D2 and the sum of the emitter collector resistance in its conducting condition and diode D3 respectively.

Title: Leaching of non-ferrous metals from ores containing metalloids
IPC: C01G1/00
Filed: 1955-08-08
Abstract: Copper, nickel and/or cobalt are extracted from ores thereof containing also arsenic, antimony, selenium and/or tellurium by forming a slurry thereof in aqueous sulphuric acid, supplying therein 1 to 5 per cent by weight of nitric acid based on the total liquids of said slurry and maintaining said slurry in the presence of an oxygen-containing gas at the aforesaid nitric acid concentration and a temperature of 100 DEG  to 150 DEG  C.  The copper &c. and any iron present pass into solution as sulphates whilst the arsenic &c. primarily remains in the residue as oxide.  In the case of arsenic, some of the arsenic is dissolved as As2O3 which is in part precipitated when the liquor is cooled.  Preferred procedures include the use of a pressure of 10 to 200 p.s.i.g. (although open vessels may be used) and the addition of a further quantity of ore to the residual liquor to eliminate nitric acid.  A part of the sulphuric acid necessary for sulphate formation may be derived from the sulphur in the ore and the liquor after removal of metal values will then generally be recycled.  The nitric acid may be supplied in the slurry by means of nitrogen oxide gases.
