Abstract: 1,072,354. Bag-filling apparatus; pneumatic conveyers. ST. REGIS PAPER CO. June 1, 1964 [June 14, 1963], No. 22560/64. Headings B8A and B8C. Pulverulent or granular material is filled into a valved bag 24 from a hopper 63 by means of apparatus 10 in which a bin 12, closable at the hopper exit by a valve 16, is subjected to air or other gas under pressure from a supply line 40, thereby causing the material to be expelled through a filling tube 18. The compressed air is disseminated in the bin 12 through an apertured member 48, the entrained material being forced up the tube 18 by more air fed through an air-pervious membrane 17. The filling is controlled either by cutting off the air, or by a pneumatic closure 32, or by a releasable clamp in the filling tube adjacent a flexible coupling 20. The bag is held by an electrically or pneumatically operated clamp 26 and is supported on a chair 52. In a modification the filling tube (84), Fig. 2, lies wholly outside the bin (62) and compressed air is supplied only through a disseminator (78). A clamp (94) in the filling tube enables the flow of material to be cut off. The material is compressed as it passes up the filling tube (84). In each embodiment, the valve 16 may either operate intermittently to cut off the flow from the hopper 63, or it may control a continuous flow, even though the compressed air is supplied intermittently to the bin 12.

Title: Improvements in or relating to a process and machine for the manufacture of bevel gears
IPC: B23F9/10
Filed: 1953-08-18
Abstract: 759,501. Gear-cutting. KLINGELNBERG, G., JAEGER, G., KLINGELNBERG, H. W., and BAUM, C., [trading as KLINGELNBERG SOHNE, W. F.]. Aug. 18, 1953 [Sept. 12, 1952], No. 22729/53. Class 83 (3). A process for cutting curved-tooth bevel-gears 1 consists in rotating a cutterblock about its axis 8 and simultaneously causing it to perform a planetary movement about the axis 0 of the imaginary crown-wheel represented by the paths of its cutter-blades, the cutterblock comprising two parts carrying the blades for cutting the concave and convex flanks respectively, the sets of blades interengaging and the axes 8, 9 of the two parts of the block being offset from each other. The axis 8 of the blades which cut the concave flanks 5 is also the axis of adjustment of a mounting 31, the position of which is indicated by a scale 12. The mounting 31 can be adjusted radially of a face-plate 11. The convexflank blades rotate about axis 9, the distance 8-9 being greatly exaggerated in Fig. 1. The mounting is adjusted so that the line 8-9 is parallel to a line 13 perpendicular to the tooth curves 5, 6 at the common cutting-point 7. The radii of the circles 15, 16, and 15<SP>1</SP>, 19, are in the same proportion as the number of starts in the cutter-head to the number of teeth in the crown-wheel. The teeth cut have localized bearing and the teeth may be modified by setting the line 8-9 other than parallel to the line 13. In a practical embodiment of the head, four concave-cutting blades 22, Fig. 2, are mounted on a ring-gear 27 by annulus 21, bolts 25 and studs 26. The gear is rotatable on a slide 29 adjustable on the mounting 31 by a screw 32, together with its driving-gear 33, 36. The four convex-cutting blades 24 are mounted on a ring-gear 271 journalled on a pivot 34 (axis 9) in the mounting 31 coaxially with a driving shaft 40 which rotates the gears 36 and also the gear 271 through gearing 35, 34. In a modification, the distance 8-9, Fig. 5, is not adjustable, two concave-cutting blades 43 and two convexcutting blades 45 being carried on blocks 42, 44 mounted detachably on an annular ring-gear 46 and a driving shaft 48 respectively. By angular adjustment of the block 42, the blades may cut spaces wider or narrower than the teeeh at the pitch plane, thus enabling the amount of back-lash to be set. The cutting blades may be circular as described in Specification 676,050. A further head, Fig. 7, has ten concave-cutting blades 59 and nine convexcutting blades 60.

Title: Servo operated declutching control
IPC: B60T13/56
Filed: 1928-08-07
Abstract: 295,263. Triggs, W. W., (Servo-Frein Dewandre Soc. Anon.). Aug. 7, 1928. [A Specification was laid. open to inspection under Sect. 91 of the Acts, Aug. 7, 1928]. Controlling-apparatus, arrangements of hand, foot, and transmission gear in conjunction with; hydraulic or pneumatic transmission; relay or power apparatus.-A servomotor de-clutching apparatus, particularly for motor vehicles, comprises a pedal acting on the clutch member and a distributor controlling the servomotor by meansof two inter-connected levers, the relative movements of which control the distributor, in such a way that one part of the effort exerted by the servomotor upon one of these levers is imposed upon the clutch pedal in the opposite direction to the force exerted thereon bv the driver. Theservomotor may be electric, electro-magnetic, or fluid-operated. In the construction shown, a. vacuum-operated servomotor 4 is employed controlled by a pedal 11, and a controlling unit is formed comprising the clutch control, a brake servomotor 26 controlled by a pedal 30, and an accelerator pedal 29. All three pedals are mounted on a common shaft 28, the brake and clutch members are inter-changeable, and the unit may be mounted on either side of the steering column. The clutch pedal 11 is connected at 10 by a link (not shown) to an arm 9 mounted with some play at 9<11> on a fixed shaft 14, and. having this loosely-mounted end connected by a link 7 to a distributor 6 controlling the vacuum and atmospheric valves 20, 21 of the power cylinder 4. The arm 9 is also connected by a. pivot pin 12 to an arm 13 pivoted on the shaft 14 and connected at 15 by a link 17 to the clutchoperating fork 16. Lastly, an extension of the arm 9 is connected at 18<1> by a chain or cord 19 to the power piston 5. Thus, when the pedal 11 is depressed the arm 9 turns about the pin 12, and the play at 9" allows the distributor to be moved to open the vacuum valve; the piston 5 is now moved rocking the arms 9 and 13 and thereby moving the fork 16 to disconnect theclutch. Since the piston is connected to the arm 9 below the pin 12, which is held fast. momentarily by the clutch fork, the first effect of the piston movement is to apply a force to the pedal 11 opposing the pressure of the driver's foot. This is stated to make the control more sensitive. In a modification, the power piston is connected to an extension of the arm 13 instead of to the arm 9.

Title: Chrome dyestuffs of the phthalocyanine series
IPC: C09B47/26
Filed: 1952-09-11
Abstract: The invention comprises chrome dyestuffs obtainable by reacting at temperatures up to 100 DEG C an aromatic amino -ohydroxycarboxylic acid or ester thereof, containing at least one hydrogen atom attached to the amino nitrogen atom with a phthalocyanine containing at least one sulphochloride group in at least one phenylsulphone substituent, and subsequently sulphonating, if desired.  Subsequent sulphonation is unnecessary if the hydroxycarboxylic acid contains a sulpho group. The products form water-insoluble lakes with chromium salts.  The sulphochlorides may be obtained by reaction of chlorosulphonic acid and thionyl chloride on the phenylsulphonyl phthalocyanines. In examples, 2-hydroxy-5-amino-3-sulphobenzoic acid is reacted with a copper phthalocyanine obtained from diphenylsulphone-3, 4-dicarboxylic acid alone or mixed with an equimolecular amount of phthalic anhydride, or from diphenyl sulphone -3.4-dicarboxylic acid -3\sv-sulphonic acid.  Also in examples, 2-hydroxy-5-methylamino-3-sulphobenzoic acid is reacted with a sulphochloride of the phthalocyanine obtained from diphenysulphone-3,4-dicarboxylic acid.  Other acids specified are 2-hydroxy-5-aminobenzoic acid, 2-hydroxy-3-amino -5-sulphobenzoic aicd, 2-hydroxy-5-(4\sv-aminobenzoylamine)-benzoic acid, 2-hydroxy-5-amino-4-methyl-benzoic acid.
