Patent GB-753916-A (GB)
Title: Apparatus for indicating the extent to which a tool or a machine tool has been used
Inventor: CROSS RALPH E
IPC: B23Q13/00
Filed: 1954-04-30
Abstract: 753,916. Machine-tool details. CROSS CO. April 30, 1954, No. 12643/54. Class 83 (3). Apparatus for indicating the extent to which a tool of a machine - tool has been used, comprises a recording device having a movable member recording the number of times the tool has been used, means actuated by each use of the tool to adjust the movable member, and means cooperating with said recording device to provide a visual indication of the number of times more which the tool may be used before it is estimated to require sharpening or replacement. In one system, a double plunger-pump 10, Fig. 1, having a liquid reservoir 12 and provided with a reversing valve 14, supplies liquid through pipes 16, 18 to a measuring - valve 20. The latter ejects a measured amount of the liquid charged thereto into a pipe 22 and a glass indicator tube 26, excess liquid returning through the pipes 28, 30. One pump is operated once for each operation of the tool. A float 32 in the tube rises and finally operates a switch 34 to stop the machine when a tool requires sharpening &c. An all-electric system is also described with a timer-clock operated by some moving part of the machine, such as an indexing member which moves the same number of times as the tool is used. The timer momentarily closes tool-indicating circuits, and indicator-motors with hands are moved to indicate the number of times each tool has been used. The motors are connected to cams which stop the machine when a tool has completed its estimated useful life.

Abstract: 855,879. Conveyers. GREBE, K. April 23, 1957 [April 20, 1956], No. 12912/57. Class 104(2). A conveyer comprises conveyer belt sections 3 supported by rollers 7 moving in a supporting structure, consecutive pairs of rollers of each section being pivotally connected by rigid members, an endless chain 1 being detachably coupled to the conveyer belt sections and being supported and guided by pairs of guide rollers 6 secured at intervals to the chain. The rollers 6 and 7 may run on the same U-shaped guide rails 5 and 5<SP>1</SP>. The conveyer belt sections are pushed and/or pulled by guide roller units, each unit comprising two pairs of guide rollers and the drive is disengaged by inclining a guide rail, the rollers then move on separate rails and the conveyer belt sections may engage another endless chain to drive the conveyer belt sections along another rail. Guide rollers 8, 9 on the conveyer belt sections and chain roller units have flanges which engage the flange of a guide rail. The rollers 6 and 7 may move along superimposed rails and the conveyer belt sections may be detached from the driving chain units by increasing the distance between the tracks. The guide rails may be adjacent. The chain may be detachably connected to the middle of each conveyer belt section which may be manually braked without arresting the chain. The roller units may engage the belt sections frictionally as by means such as a spring-urged cranked lever pivoted on the units which engages the undersurface of the belt section and is automatically disengaged when an extension strikes a control rail positioned at end sprockets or switches. Each belt section may have a covering rubber belt or a rubber belt may cover several sections.

Title: Process for the recovery of sulphur dioxide from gases containing same
IPC: C01B17/60
Filed: 1937-05-06
Abstract: In recovering sulphur dioxide by the process claimed in the parent Specification, with the employment of sodium compounds, the sodium sulphate which passes into solution in the aqueous phase of the absorption mixture is removed from the solution as Glauber salt in a continuous or intermittent manner by cooling the solution or a portion thereof to a temperature of about 2 DEG  C. or less, the solution thus freed from Glauber salt being returned to the absorption process.  Preferably, the cooling is effected at a stage when all the sulphuric acid is in combination with sodium and no sulphates of the organic bases are present.  The solution or part thereof may be replenished by the addition of sodium oxide or hydroxide or sodium salt of a weak acid prior to or after the crystallization of the Glauber salt.  The solution to be cooled may have been separated from an absorption mixture still containing traces of SO2.  The invention may be applied to the process described in the parent Specification when modified in the manner claimed in Specification 480,519.

Title: Improvements in or relating to Carburettors.
IPC: F02M9/127
Filed: 1918-08-17
Abstract: 129,497. Thornycroft & Co., J. I., and Thornycroft, T. Aug, 17, 1918. Spray carburettors.-The primary air supply is controlled by a sliding choke-tube s operated by hand or by governor. Two nozzle-tubes c, d are immersed in the float-chamber b, one delivers direct through a nozzle e into the mixing-chamber f, the other through horizontal nozzles i into a small chamber k where it is mixed with air entering through a small adjustable valve p. The chamber k has exits near its lower part at n, so that when the choke-tube is in its lowest position (say at starting) there is practically no suction past n, and only the nozzle e is in action giving a rich mixture. As the choke-tube is raised, the nozzles i come into use. In a modification, the nozzle c is dispensed with, its function being served by extra holes in the chamber k, these holes being just under the choke-tube when in its lowest position, so that then there is a strong suction past these extra holes. The float 1 acts on a lever 2 pivoted at 3 and carrying a valve 4 and a flooding-knob 9.

Title: Improvements in or relating to filtration elements and methods of making the same
IPC: D21J3/00
Filed: 1957-04-26
Abstract: In making a tubular filter cartridge, cellulosic fibres are pulped in a liquid containing between 85 and 75% by volume of a non-polar organic liquid, e.g. methyl or isopropyl alcohol or ethylene glycol, and between 15 and 25% of water, to form a pulp containing between 2 and 6% of fibres, computed on their dry weight, and the pulp is diluted with more liquid until it contains between 0,3 and 0,8% of fibres and is then vacuum-felted on a foraminous tubular former, e.g. by applying suction to the interior of the tubular former immersed in the diluted pulp.  The cartridge is dried, preferably by withdrawing heated air through it from the outside to the inside.  If necessary, its outer surface is trimmed.  The cartridge is impregnated with a solution of a resin, as by withdrawing the solution through it from the outside to the inside.  The resin solution may be a solution of melamine-, phenol- or ureaformaldehyde resin or polyvinyl chloride in aqueous isopropyl alcohol.  Excess resin is removed from the cartridge by drawing warm air through it from the outside to the inside.  The cartridge is then dried and cured by forcing hot air through it from the inside to the outside.  Curing may be completed in an oven.  The cured cartridge may be trimmed to a desired size. Specification 677,515 also is referred to.
