Title: Improvements in and relating to the production of sheets, bands and objects of metal for electrical purposes
IPC: C21D1/78
Filed: 1934-07-24
Abstract: Metal sheet or wire is treated to obtain large crystal grains of 1/2 to 10 sq. cms. and improved electrical properties, e.g. small power loss, high magnetic induction and high maximum permeability by a series of hot or cold deformation by forging, rolling, pressing or drawing with interposed annealing, then by critical internal straining, and by a final recrystallizing heat treatment at a critical temperature, the silicon content of the metal, ,5-5 per cent determining in inverse ratio the degree of deformation which varies from 35 to 5 per cent and also determining the final straining reduction 12 to ,3 per cent and also determining the recrystallizing temperature treatment at from 900-1250 DEG  C. all in accordance with the tables set out.  The heating between the deformations is from 800-850 DEG  C.  After each intermediate heating and/or after the recrystallizing heating the steel may be quenched in water or other suitable cooling liquid and then again heated to 500-800 DEG  C. Prior to the final critical straining, the normalizing heat treatment may be above or near the A3 point to 900-1250 DEG  C., depending on the silicon content, between ,5 and 5 DEG .  The critical straining, particularly with high silicon content metal, may be brought about by heating above 900 DEG  C. and quenching in water at 0 DEG  C., or in a cooling liquid at below 0 DEG  C.  After the recrystallizing heat treatment it may be held at 700-850 DEG  C. for e.g. 10 hours to increase the permeability.

Title: Method and apparatus for determining the presence and/or concentration of predetermined particulate material in liquid
Inventor: YOUNG DAVID CHARLES
IPC: G01N23/223
Filed: 1968-05-08
Abstract: 1,248,738. Monitoring metal particles in liquids. ROLLS-ROYCE Ltd. 7 May, 1969 [8 May, 1968], No. 21744/68. Heading B1D. [Also in Division G1] The presence and/or concentration of a particulate material in a liquid is determined by first separating any such material from the liquid and then irradiating it using a radioactive source and measuring the emitted radiation stimulated by this irradiation. The invention is described with reference to the determination of solid particles in lubricating oil (e.g. steel particles from bearing balls, rollers or track or phosphor-ibronze particles from the cage), but is applicable also to the determination of gold particles in water. In the apparatus of Fig. 1, oil is directed from inlet pipe 14 tangentially onto a cylindrical filter element 11 e.g. of paper, supported by disc 12 and rod 13. Oil passes through and out via pipe 15. Solid particles drop and are guided by baffle 21, through a trough 20 whose boundary is surrounded by a ring 17 of X-ray emitting radioactive material which causes the particles to emit characteristic X- radiation. A particular characteristic spectral line e.g. that of iron is investigated by the use of a pair of detectors 22, 23 (of the scintillation counter-type using thallium-activated sodium iodide crystals provided with respective radiation filters, one adapted to pass radiation of energies up to just below the characteristic spectral line of interest and the other to just above. Subtraction of the counts obtained at 32 provides an indication of the presence or quantity of the element and can operate an alarm 35 if a predetermined quantity is exceeded. In alternative arrangements, one detector with two radiation filters, carried on a rotatable mount and used sequentially, may be used; three radiation filters may be used to investigate two elements; the ring 17 may be substituted by a coarse mesh of radioactive substance. Means may be provided to knock the solid particles off the filter element e.g. the vibrations provided by a gear pump connected to the outlet 15.

Patent GB-479860-A (GB)
Title: Improvements in clothes washing installations for laundries
IPC: D06F95/00
Filed: 1936-08-12
Abstract: 479,860. Washing-machines. PYNE, A. H., and RICHARDSON, J. R. S. Aug. 12, 1936, No. 22195. [Class 138 (ii)] In a laundry installation there is provided at a higher level than the washing-machine 1 a break-down or soaking receptacle 2 with a connecting shoot 3. For bag-washing, the receptacle 2, shoot 3 and machine 1 are all provided with a corresponding number of divisions so that after treatment in the soaking receptacle each bag travels to a separate compartment in the washer. The soaking receptacle is rotated through 180‹ to discharging position by a pinion 15 and quadrant 14 rocked by a fluid or other motor 13 ; the latter can be energized only when an exhaust valve 20 positioned near the operator of the receptacle 2 is closed and when the lower portion 5 of the shoot is swung down from the position shown in dotted lines to that shown in full lines, wherein it projects into the loading apertures of the washer. When the shoot is in this operative position, the operator of the washer rotates a locking shaft 9, carried by the stationary casing of the washer, to lock the shoot and to open the supply valve 7 to the motor 13 by a lug 8, the valve being carried by the movable portion of the shoot. The valve 7 supplies the motor through a needle valve 18, and the motor exhausts through another needle valve 19 when the valve 20 is opened. If the washer operator opens valve 7 before valve 20 is closed, fluid-pressure byepasses the cylinder 13 at 21 and operates a whistle 22. The receptacle 2 is returned to loading position by a spring 16 when the cylinder 13 exhausts following the opening of valve 20. Springs 11 maintain the portion 5 of the shoot in its extreme positions.

Abstract: 456,779. Cigarette -making or like machines. QUESTER, C., and QUESTER, K., (trading as KOLNER WERKZEUGMASCHINENFABRIK VON W. QUESTER), 282, Berrenratherstrasse, Sulz, Cologne, Germany. Aug. 6, 1935, No. 22207. [A Specification was laid open to inspection under Sect. 91 of the Acts, Feb. 4, 1936.] [Class 130] In a cigarette or like machine radial adjustment of a knife carried .by a rotating carrier is effected through a differential gear while the machine is in operation. As shown, the knife 6 is carried by a toothed rack 10 in a carrier 1 which is rotated about a shaft 2. The differential gear comprises a bevel wheel 26 which is driven at twice the speed of the carrier 1 through a coupling 37, a second wheel 27 which is normally held stationary and a third wheel 28 which is carried by the casing and rotates at the same speed' as the knife carrier. To adjust the knife 6, a coupling 32, 33 is disengaged and the wheel 27 rotated by a hand wheel 35. The differential gear then causes a spur wheel 21 to rotate a wheel 20 which through gearing 16, 12, 11 operates the rack 10 to move the knife 6 radiallv in the carrier. The bearing 18 of the shaft 17 may be mounted eccentrically in the carrier so that the gearing 16, 12 can be disengaged and the knife adjusted or exchanged when the cutting mechanism is out of operation. In modified constructions, (1) the differential gear is formed by spur wheels, (2) the wheel 35 is mechanically rotated either intermittently or continuously, (3) to obtain a continuous adjustment of the knife, the carrier 1 is directly connected to the wheel 26 and (4) the carrier 1 may have a reciprocatory motion, parallel to a cigarette rod, as well as a rotary motion and if the differential gear is not to reciprocate the breadth of the wheel 21 is such that it remains in engagement with the wheel 20. The invention may be applied to a knife for cutting lengths of tobacco rod for insertion in paper tubes or to a knife for cutting cigars from a rod.

Abstract: 1499196 Optical projectors PENTACON DRESDEN KAMERA-UND KINOWERKE VEB 22 May 1975 [13 Aug 1974] 22309/75 Heading G2J  A shutter 7 is pivoted out of the projection light path 12 in response to either (a) the movement of a slider from a magazine into the projection gate by means of a carrier 1 or (b) the movement of a slide manually into the gate from the opposite side of the light path to that of the carrier 1. As shown, when carrier 1 is moved leftwards to move a slide into the gate, a lip 3a on the carrier engages a web 6a on a closing lever 6 to pivot lever 6 free from a stop 7a on the shutter. The slide itself engages a ramp arm 10a to pivot a blocking lever 10 free from a stop 7b on the shutter; a spring 9 then moving shutter 7 to its open position. When carrier 1 is retracted a spring 8, stronger than spring 9, returns lever 6 and thus shutter 7; lever 10 being returned by a spring 11. When a slide is manually inserted it engages ramp arm 10a to pivot lever 10 clockwise. This (a) frees lever 10 from stop 7b and (b) engages an arm 10b with the web 6a to pivot lever 6 free from stop 7a; shutter 7 then being opened by spring 9 as before.

Filed: 1952-09-05
Abstract: 743,985. Induction relays. ENGLISH ELECTRIC CO., Ltd. Sept. 4, 1953 [Sept. 5, 1952], No. 22379/52. Class 38(5) In an induction relay having an operating magnet 2 and one or more shaded poles 4, a capacitator 5 is inserted in series with one or more shading windings to vary the time characteristic of the relay. The E.M.F. induced in the shading winding has a lagging phase with respect to the current produced by it and this phase lag increases as the pole saturates with high currents thereby shifting the phase of the flux in the shaded pole relative to the flux in an unshaded pole and so varying the, torque on the disc 1. Without a capacitor, saturation would make the relay lose its inverse square characteristic. With a suitable capacitance the phase difference of fluxes approaches 90 degrees with saturation so that the torque is then a maximum and the above effect of saturation is compensated for. Alternatively if it is wished to provide a constant time of operation for high currents, the arrangement of Fig. 2 may be used. In this, the leakage flux shown by a dotted line exerts a restraining torque which increases as the magnet saturates and to enhance this effect the section of the core in the coil 2 may be reduced and capacitance 5 is chosen so that the phase difference between the fluxes is 90 degrees for low currents and becomes less for high currents causing saturation. In a further arrangement, Fig. 3 (not shown) there are two pairs of shaded poles, each with a capacitor in series with it.
