IPC: B24B5/06
Abstract: 132,031. Cameron, J. Sept. 3, 1918. Round holes, enlarging and trueing.-A grinding-disk is carried by a sleeve, which is driven on and supported by a spindle mounted, for a circular traversing motion, in a member such, for example, as the face-plate of a lathe. The grinding-disk 31 is secured by a bolt 32, nut 28, and screw 30 to the end of a sleeve 14 enlarged as shown at 15 to form a pulley to enable it to be driven loosely on a spindle 6, which is adjustably mounted in a face-plate to secure for the grinder the necessary eccentric movement relatively to the face-plate. Ball or roller bearings 21 are provided between the sleeve 14 and spindle 6, and a nut 24, felt washer 27, and packing-gland 26 at one end of the sleeve 14 and the nut 28 at the other end serve to keep the various parts in position on the spindle 6. A washer 33<1> of relatively soft material is clamped between the grinding- disk and the sleeve 14, and is provided with a boss, which, together with a flanged bushing 34, affords a seating for the grinding-disk. Lubricant may be injected through the bolt-opening in the nut 28. The sleeve may be driven more slowly than when used for grinding to adapt the apparatus for boring, and a battery of grinding-elements may be used for simultaneously grinding the cylinders of an engine.

Title: Improvements in or relating to colour sorting machines
Inventor: FRAENKEL HERBERT
IPC: B07C5/342

Abstract: 885,287. Valve gating circuits. GUNSON (SEEDS) Ltd., R. W. Dec. 11, 1958 [Oct. 20, 1958], No. 13418/61. Divided out of 885,283. Class 40(6). [Also in Group XL(b)] In a sorting machine the object 2 to be sorted is illuminated by infra-red and visible light. Light reflected from the object passes through the aperture in a diaphragm 55, this aperture being larger than that in a second diaphragm 56. It is arranged that diaphragm 56 transmits only infra-red light except at the aperture, where it transmits visible light only. The visible light passes via a part-silvered mirror 53<SP>1</SP> to a photo-electric viewing means 4<SP>1</SP> whose output feeds an amplifier 59. A valve 61 acts as a gate. When no object 2 is being examined the gate is shut because the grid/cathode is in effect short-circuited by a pair of diodes 67, 68 and low value resistors 64, 65. However, when an object 2 is present infra-red light from the object passes through an infra-red filter 57 to a photocell 58. The cell output is amplified at 62 and feeds a phase splitter 63 so that the grid/cathode circuit is again made and a signal coming from amplifier 59 is amplified by valve 61 to control the sorting operation. The valve 61 will be opened before a signal arrives from amplifier 59 because, as the object 2 falls through the inspection zone, light will strike the infrared transmitting portion of diaphragm 56 before it strikes the visible light transmitting portion. Similarly, the valve will not be shut again until after amplifier 59 has ceased to give a signal. Specifications 885,285 and 885,286 are referred to.

Abstract: 679,360. Cathode-ray tubes. SOC. ALSACIENNE DE CONSTRUCTIONS MECANIQUES. June 6, 1951 [July 13, 1950], No. 13462/51. Class 39 (i). [Also in Group XL (c)] In the receiver of a pulse code modulation signalling system (see Group XL (c)), a step wave, with levels corresponding to the pulse amplitudes, is applied to amplifier 10, the pushpull output of which is fed to the vertical deflecting plates 3 of a cathode-ray tube 1. The horizontal deflecting plates 4 are supplied with a push-pull sawtooth voltage from amplifier 13 supplied from the scanning generator 12. The cathode-ray beam in tube 1 is thereby moved vertically to a position depending upon. the levels of the step wave from circuit 10 and scanned horizontally across the mask 6 and anode 5 once during the occurrence of each level. The solid portion of the mask is shown shaded in Fig. 2 in which A is the rest position of the beam, AB a typical vertical deflection and BC the corresponding horizontal deflection. During the latter, a current pulse of duration corresponding to the distance BD is produced in the anode 5, this duration being uniquely related to the corresponding vertical deflection AB. The mask is so cut that the durations of the pulses at the anode 5 are proportional to the signal amplitudes represented by the incoming code groups.

Title: Improvements in and relating to carburettors of internal combustion engines
IPC: F02M7/11
Filed: 1932-05-10
Abstract: 401,324. Spray carburetters. MAXWELL, R. M. S., Queen's Hotel, South Farnborough, Hampshire. May 10, 1932, No. 13477. [Class 7 (iii).] The float chamber air-space of a carburetter is connected with the induction pipe through the intermediary of a valve controlled in accordance with the movements of the throttle valve. In the construction shown in Fig. 1, a valve 2 controls the communciation between ports 12, 13 leading to the induction pipe, preferably above the throttle valve, and the space above the fuel in the float chamber. The valve is controlled by a lever 3 mounted on the spindle 4 of the throttle valve and is frictionally constrained to rotate with the throttle. As the throttle valve is opened by moving the lever 6 in the direction of the arrow a, the valve 2 is closed by the lever 3 which engages a collar 9. As the throttle valve is closed, the lever 3 first moves with lost motion and then opens the valve 2 to connect the float chamber with the induction pipe so that the depression existing therein is communicated to the float chamber to interrupt the fuel supply to the nozzle. As the throttle reaches the slowrunning position, the throttle lever 6 contacts with one arm of a bell-crank lever 20 to move the opposite end into engagement with a lug 21 on the lever 3 and rotate it against frictional constraint to close the valve 2 and re-establish the flow of fuel to the nozzle. In a modified construction, the valve 2 is closed as the throttle approaches the slow-running position by an adjustable cam formed on an extension of the spindle 4 which engages a flat surface on the lever 20. The valve 2 may also be closed manually when desired. In a further construction. Figs. 3 and 5, the valve 2 is controlled electrically. The valve is formed of magnetic material and held either by a spring 25 or by gravity on the port 26 which leads to the induction pipe. A solenoid 28 lifts the valve when a circuit is closed by a switch formed by a normally stationary contact 33 and a movable contact 32 carried on a lever 29 rotatably mounted on the throttle spindle 30 with a friction grip. When the throttle valve is nearly closed an extension 39 on the lever 31 moves the contact 33 to open the solenoid circuit and thus permit the valve 2 to seat and cut off the communication between the float chamber and the induction pipe. To destroy the depression in the float chamber when the valve 2 is closed (1) the valve chamber or the float chamber is put into communication with the atmosphere through an adjustable valve, or (2) the valve 2 may be provided with a seating 42 at each end to put the valve chamber or float chamber into communication either with the induction pipe or with the atmosphere. The valve 2 may be operated pneumatically.

Abstract: 1,186,664. Alkali metal fluorophosphate. CHEMISCHE WERKE ALBERT. 20 March, 1968 [8 April, 1967], No. 13562/68. Heading C1A. A continuous process for the production of an alkali metal (A.M.) mono-fluorophosphate (e.g. Na2PO3F) comprises making a mixture of an A.M. fluoride (or A.M. hydrogen fluoride and an A.M. salt whose acid component is preferably volatile under reaction conditions) and an A.M. meta-, pyro-, or poly-phosphate (or a phosphate which gives one of these on heating) ; continuously feeding this mixture into a heated reactor and simultaneously discharging product, the conditions of feeding, heating and discharging being such that a layer of solid reactant is maintained on top of the molten reaction mixture. The M2O : P2O5 ratio may be about 2 : 1 and the mixture may include P2O5. The said acid component may be carbonate. The temperature may be 625-750‹ C. The M2O : P2O5 : F ratio may be 2 : 1 : 2. The starting material may contain NaF and (NaPO3)3. The phosphate used may be Mandrell salt, i.e. (NaPO3)n where n is 40-70, Na5P3O10, tripolyphosphates, Na2H2P2O7 or NaH2PO4. However when using phosphates whose condensation supplies water it is preferably to carry this out prior to the process of the invention. If the phosphate is such that AM : Phosphorus ratio is higher than 1 : 1, e.g. Na5P3O10, then P2O5 may be added to give an M2O : P2O5 of about 2 : 1. The parts of the reaction vessel in contact with the reaction mixture may be made of graphite, iron, silver or platinum and the vessel may be cylindrical, conical or funnel shaped.

Filed: 1922-05-17
Abstract: 201,307. Barker, R. W., (American Bank Note Co.). May 17, 1922. Photo-mechanical printing-surfaces.-Printing- plates for printing negotiable securities, banknotes, &c. to prevent fraudulent reproduction are obtained from a mechanically-produced line geometrical design, which is photographically enlarged, and the lines in said enlargement are modified so as to be distinguishable readily from mechanically-produced lines, the modified design being reduced photographically and the printing- plate obtained by a photo-etching process from the reduced design. A number of such printing- plates may be obtained for printing the notes in several colours, each plate being arranged to contain a portion only of the complete design. As applied to obtaining four printing-plates, a geometrical line design is cut :n a darkened glass plate, and an enlarged bromide or like positive such as B, Fig. 2, is obtained therefrom. The design contains a series of overlapping scrolls a, b, c, d, and comprises darkened portions e where a large amount of overlapping occurs. A photographic negative is obtained from the positive B, and by a photo-etching process four positive prints are transferred to metal plates as C, Fig. 3. The plates C are then treated with a brush and a light-reflecting paint so as to block out the scrolls b, c, d from one plate, and leave only the scrolls a, and to leave only the scrolls b, c, d respectively in the other plates. Each pate so formed is treated by thickening in a regular or irregular manner the portions a and the other portions a' may be strengthened if they are defective. Arbitrary markings as f, Fig. 3, may be made in the portions e of the design. Also the lines a<1> may have arbitrary figures printed over them. From the designs on the plates C printing-plates are obtained on a reduced scale by a photo-etching process. Instead of printing from four plates as C, two plates C may be cut in two and four printing-plates obtained each of which contains a half of a portion of the design, and the final print is obtained in four colours from the four half-size printing-plates. The process mav be modified in other respects, e.g. by employing sectional inking as described in Specification 200,294, [Class 100 (ii), Printing processes &c.], each plate may be printed from in several colours, so that the complete design may contain a large number of colours.
