Title: Improvements in or relating to electromotor-driven textile spindles
IPC: H02K7/16
Filed: 1962-02-17
Abstract: 1,009,372. Spindle-arrangement. SPINDELMOTOREN UND MASCHINENFABRIK A. G. Feb. 17, 1962 [Feb. 17, 1961],No.1115/62. Heading D1D. [Also in Divisions F2 and H2] In a spindle arrangement comprising an electromotor of which the rotor 19 and stator 18 are respectively fixed to a spindle shaft 5 and a bearing sleeve 4, the latter containing foot and collar bearings 6, 11 for the shaft, the sleeve is resiliently supported for lateral oscillation in a housing 1 adapted to be mounted on a frame 3, the sleeve and housing being connected to each other by resilient means located within the stator. In Fig. 1, the resilient connexion is provided by spaced and staggered slots 14 in the housing while that part of the housing above the slots is turned over and shrunk to compress axially towards a flange 7 on the sleeve an assembly of rings 9, 12 and the race 10 of the bearing 11. The stator is carried between end-rings 20 on a sleeve 16, the lower ring being accommodated on a shoulder of the sleeve while the upper one is mounted between a spacer 22 and a circlip 23. The sleeve is forced over the upper part of the housing, the exterior of which is slightly conical while the bore of the lower part of the sleeve is larger than the external diameter of the housing to allow the sleeve 16 and the stator to follow lateral movement of the sleeve 4. In other forms, the resilient connexion is provided (a) by replacing the slots in the upper part of the housing by slots in a member depending from the flange 7 between the sleeve and the housing and forced into the bore of the housing and the sleeve that carries the stator is forced over the upper part of the sleeve which accommodates the upper bearing (Fig. 2, not shown); (b) by integral or separate parallel and angularly offset ring segments connected by bridge-pieces; (c) by an annulus of steel of U- section; (d) by a diaphragm with or without perforations; (e) by a spring or (f) by a compressed rubber sleeve. In another form, the stator is arranged outside the rotor and is supported by a cylindrical casing outside the stator connected to the housing or sleeve 14 above their yielding connection. Specification 725,245 is referred to.
Patent GB-563568-A (GB)
Title: Improvements relating to machines for moulding plastic materials, or for use in making die castings from metal
IPC: B30B15/16
Filed: 1943-01-25
Abstract: 563,568. Hydraulic presses. E.M.B. CO., Ltd., SMITH, S., and COCKERILL, W. H. Jan. 25, 1943, No. 1247. [Class 69 (ii)] [Also in Groups V and XXII] The movable platen e, Fig. 6, is advanced towards the fixed platen by pneumatic or hydraulic pistons i ; the rate of movement of the platen is controlled by an hydraulic ram m; and when the mould halves carried by the two platens have been brought together, a final pressure is exerted on the movable platen by a pneumatic or hydraulic piston-rod p which acts through the medium of the liquid in the ram cylinder h. Material cannot be injected into the mould before this final pressure has been exerted. As the platen advances, liquid escapes from the front of the ram cylinder to the back via valve s, Fig. 3, reservoir r and valve t. Valves 2, 3 and 4 control respectively the operating pistons i, the " intensifying " piston-rod p, and the means for injecting material into the mould. The valves 2, 3 and 4 are operated by manual movement of a spindle v carrying cams 8 and an arm 9. The valves s, . t are operated by levers z actuated by a cam spindle y which is connected by chain-and-sprocket gearing to the spindle v. The spindle v is formed, at different parts in its length, with flats 10, Fig. 3, and 10a, Fig. 5, which co-operate respectively with a flat part 11 on a bar 12 fixed to and travelling with the platen, and a flat part 13 on a spring- loaded plunger 14. Operation : (a) initial angular movement of spindle v actuates valve 2 to advance pistons i and platen e ; (b) a second angular movement opens valves s, t. This movement is terminated by abutment of flat 10 on flat 11. The platen advances : (c) when the platen stops, a recess 16 in rod 12 allows a third angular movement of spindle v to operate valve 3 and apply the intensifying pressure; this third angular movement is limited by abutment of flat 10a on flat 13 ; (d) when the pressure in the ram cylinder h reaches a predetermined value, it acts through conduit 20, Fig. 5, to force plunger 14 leftward, thus positioning a recess 15 in the plunger to allow a fourth angular movement of the spindle v, which results in actuation of valve 4 and consequent injection into the mould. When, through improper adjustment, the platen e moves too far, an abutment 22 on rod 12 moves lever 23 to open valve 24 and relieve the intensifying pressure. The hand lever (not shown), which operates spindle v, may co-operate with adjustable abutments as described in Specification 547,641. There may be only one (axiallyarranged) piston i.

Title: An improved mechanism for adjusting the stroke of a reciprocating or oscillating member, such as a die plunger in an extrusion or moulding press
IPC: F16H37/12
Filed: 1943-01-25
Abstract: 564,956. Linkwork. FORGROVE MACHINERY CO., Ltd., RUSSELL , A., PARKER, M.; and HARRIS, R. A. Jan. 25, 1943, No. 1264. [Class 80 (iii)] [Also in Group V] The invention is concerned with means for adjusting the lowermost position of a verticallyreciprocating plunger 40 while the plunger is moving. The plunger is reciprocated by a cam-operated lever 46 oscillating on a fixed shaft 42, the end of the lever having pivotally connected thereto one end of a link 47, the other end of which is pivotally connected to the plunger rod 45 by a driving pin 49. The pin 49 is pivotally connected to a link 54 pivotally connected to a pin 56 fixed on a lever 57 pivoted on a fixed pin 58. The pin 56 forms the centre of a circle of radius R, and on the circumference of this circle lies the fixed pin 58. The lowermost position of the plunger 40 is adjusted by pivoting the lever 57 about the fixed pin 58. Fig. 6 shows one position of the lever 57, the full lines showing the uppermost position of lever 46, link 47, pin 49 and link 54 and the chain-lines showing the. lowermost position of these members ; the stroke of the plunger is represented by a. Fig. 7 shows another position of the lever 57, the stroke b being less than the stroke a. The pin 49 always returns, at its acme, to a point in alignment with the fixed pin 58, the top of the stroke of the plunger being thus constant. The lever 57 is adjusted by means of a hand-operated screwed rod 61 pivoting on a pin 72, Fig. 3. At its nadir, the right-hand end of lever 46 rests on an abutment 30, whereby pressure from chamber 13 (see below) is not transmitted to cam 21 which operates the lever. The invention is described in connection with a machine for moulding and wrapping butter &c.

Abstract: 679,147. Chucks. FISCHER AKT.-GES., G. Jan. 17, 1951 [Jan. 18, 1950], No. 1324/51. Addition to 583,893. Class 83 (iii). A lathe driver comprises at least two cam levers 18 pivoted on pins 17 on a ring -11, floatingly mounted in a recess 12 on a flange 4 keyed to the conical end of the machine spindle 1, the levers 18 being pivoted so that centrifugal force on them turns the ring 11 in the opposite direction to the driver's rotation to cause the levers to grip the work 7; at least one helical spring 26 supports the floating ring and assists the centrifugal movement and is mounted in a groove 25 formed partially in the flange and ring and is secured at opposite ends to these two members. Axial movement of the ring 11 is prevented by guide plates 14 engaging a peripheral groove 16 and the rotation of the ring is imparted to the cam levers by pins 10 on the flange engaging slots 20 in the levers. The clamping surfaces of the levers are in the shape of logarithmic spirals and are knurled or serrated. To remove the work, an outer casing 23 secured by screws 21 and a re-inforcing ring 22 to the pivot pins 17 is rotated in the same direction as the normal rotation of the driver thus causing the cam levers to pivot about the pins 20, until a pin 29 and a spring-loaded ball 34 on the ring 11 engage, respectively, a stop 28 and a detent 30 on the flange.

Patent GB-791536-A (GB)
Title: Improvements in the purification of melamine
Filed: 1956-01-17
Abstract: Melamine is purified by treating crude melamine with an excess of alkali hydroxide solution (preferably potassium or sodium hydroxide solution) with reference to the content of alkali-soluble substances, at a pH value in excess of 13 and at a temperature sufficiently low for the avoidance of melamine decomposition (preferably at room temperature), if desired washing with at least 0.1 normal alkali hydroxide solution until there is complete freedom from ammelide, separating the melamine and washing it free from alkali, and, if desired, dissolving the melamine in formaldehyde solution and filtering off insoluble impurities.  Preferably 1.4 to 2.0 mols. of alkali hydroxide solution are used for each mol. of alkali-soluble impurities.  The alkali hydroxide solution used is also preferably stronger than 1.0 normal (e.g. 10 normal) and only sufficient water is added to render the resulting mixture capable of being stirred. Crude melamine prepared from urea and having a high iron content can be freed from a large part of such iron by separating the iron compounds which become enriched at the surface of the melamine-water mixture prior to the treatment with alkali.

Filed: 1917-02-02
Abstract: 112,682. Anglo-American Inventions Syndicate, (Assignees of Pritchard, C. G.). March 21, 1916, [Convention date]. Tripping-arrangemÚnts.-In a machine for collating cards, envelopes &c. from several piles and collecting them in predetermined order in a single pile, and feeding them therefrom to a printing or like machine, the envelopes are ejected singly from the lower ends of hoppers one of which 2, is shown in Fig. 18 and another 4 in Fig. 1. They are ejected by pushers 66 on oscillated arms 12 and inserted in separated piles in magazines 6, and in case of failure of any pusher 66 to eject an envelope the printing machine 11, Fig. 1, is stopped. A feeler 115 on an arm 113 is adapted to enter each magazine 6 as the pusher 66 enters it on the opposite side. If no envelope is on the pusher 66 the feeler enters far enough to reck the arms 113, 122 and rod 123 to place a block 124 on the end of the rod 123 between an arm 125 on a shaft 127 and an arm 126 on a shaft 128 rocked continuously bv a rod 130 and cam 134. When the block 124 is thus lowered between the arms 125 and 126 the arm 125 is moved to the left and rocks an arm 137 connected to a rod 138. The end of this rod 138 is thereby moved into position to engage a cam on the shaft 38 by which it is moved laterally to actuate the clutch lever 140 and stop the machine. The arm 113 is returned to its outer position by a rod 119, connected to the corresponding pusher arm 12, and is moved inwardly by a spring 136 which pulls the rod 123 downwards. The apparatus described is specially applicable for feeding to machines such as are described in Specification No. 16972 of 1914.
