Title: Improvements in or relating to position indicators for drilling and like machine tools
IPC: B23Q17/22
Filed: 1938-02-18
Abstract: 492,018. Drilling, milling, &c. machines. MACRAE, W. L., and LAPHAM, DE F. A., (trading as DALRAE TOOLS CO.). Feb. 18, 1938, No. 5121. Convention date, Oct. 7, 1937. [Class 83 (iii)] In a drilling, milling, or like machine tool a rotatable shaft is used for causing relative movement between the tool and work and a mechanical counter of the multiple register-wheel type is connected to the shaft in order to indicate relative movements of the tool and work. The tool spindle 15 is mounted in bearings 17, 18 in a quill 24, axial play of the spindle being taken up between a nut 21 thereon and the tool chuck 20, and a spacing sleeve 22 being provided between the bearings. The quill 24 is splined within a bearing 25 by a key 26 and may be clamped in any adjusted position by means of a hand-operated screw 28 engaging the key. A screwed part 33 of the quill is surrounded by a nut 31 having worm teeth 36 engaged by a worm 34 on a shaft 35, to either end of which a hand wheel 40 may be attached. Thrust bearings 32, 39 prevent axial motion of the nut and worm. The spindle is rotated by a belt drive from an electric motor, (not shown), to a multiple speed pulley 42 splined to the spindle and mounted on the casing 11 in bearings 43. A gear 61 on the worm shaft 35 drives, through an idler 62, the pinion 60 of the counter 46, the arrangement being such that one thousandth of an inch of axial movement of the spindle 15 registers one unit on the counter. The idle gear 62 is rotatably mounted on a fixed pin 63 and carries a flange 66 whereby it may be slid axially to disengage the drive to the counter, the two positions of the gear being determined by a spring detent. The counter may be set to zero when the tool engages the surface of the work by engaging a handle 55 therewith through a clutch which is normally held disengaged by a spring, and the counter will then register the depth of penetration of the tool into the work in thousandths of an inch.
Patent GB-397472-A (GB)
Title: Improvements in or relating to the manufacture of aliphatic anhydrides
IPC: C07C51/56
Filed: 1932-02-22
Abstract: Aliphatic anhydrides are produced by the thermal decomposition of the corresponding acids in presenec of a molybdate or vanadate whether simple or complex, with the exception of phosphomolybdates and phosphovanadates which are covered by Specification 394,689. Vanadates or molybdates of metals of groups 1 and 2 of the Periodic system are suitable, examples being vanadates (including metavanadates and pyrovanadates) of barium, strontium, calcium, copper and magnesium, simple or poly-vanadates of manganese, potassium, lithium and sodium, molybdates and polymolybdates of barium, strontium, calcium, magnesium, manganese, zinc and the alkali metals, and complex vanadates and molybdates such as potassium zinc vanadate, barium aluminium molybdate, and calcium tungsten molybdate. These substances may be used alone or together with other catalysts known to promote the reaction, and are preferably used in the anhydrous state.  The vapour of the acid may be passed through a molten bath comprising the vanadate or molybdate, and fusible substances may be employed to hold the catalyst in suspension if the catalyst is not fusible at the temperature employed.  Or the acid vapour may be passed over the catalyst, which may be supported upon or mixed with carriers.  Or the liquid acid containing the catalyst in suspension may be injected or sprayed into a hot reaction zone, if desired after being preheated under pressure.  The anhydride may be separated from the reaction vapours by any of the processes described in Specifications 289,972, 298,667, 303,772, and 310,863, [all in Class 2 (iii), Dyes &c.], and may be purified in any suitable way; for instance acetic anhydride may be distilled over sodium or other acetate.  The initial acid may be dilute, and the anhydride may be reacted with water so as to obtain a concentrated acid.  In an example, acetic acid of 98-100 per cent concentration is preheated to 600 DEG  C. and passed through a copper-lined tube containing pumice or kieselguhr upon which has been precipitated a mixture of barium molybdate and pyrovanadate, the tube being heated to 750 DEG  C.  The Provisional Specification mentions a large number of vanadates and molybdates.  Specifications 256,663 and 279,916, [both in Class 2 (iii), Dyes &c.] also are referred to.

Abstract: 657,237. Sun blinds. MARQUEES, Ltd., and ZONNEVELD. L. J. VAN. Feb. 28, 1949, No. 5335. [Class 20(iii)] A folding frame for a canopy sunblind of the type described in Specification 498,185, has two parallel side frames connected by longitudinal members. Each of the side frames comprises a vertical member 1, adapted to be secured to a wall, and to which is hinged a member 2, knuckle jointed at 4 to break downwardly, the member 2 extending horizontally from the member 1, in the open position of the blind.

Title: Method and apparatus for closing and sealing open-ended containers
Inventor: HARMER ERNEST GORDON
IPC: B21D51/26
Filed: 1956-02-22
Abstract: 811,513. Making electric condensers; rolling; jointing by stamping. TELEPHONE MANUFACTURING CO. Ltd. Feb. 22, 1957 [Feb. 22, 1956], No. 5473/56. Classes 83 (2) and 83 (4). In a method of closing and sealing an open end of a non-circular can an inward projection is formed in the wall of the can at a predetermined distance from the open end and a closure member inserted to rest upon the projection, whereupon the edges of the can are turned over inwardly to engage the closure member, by means located relative to the can by reference to the projection. A rectangular extruded aluminium container 24 with corners rounded to a radius of approximately “ inch is rotated by a knurled drive roller 18 while held between a disc 15 and a plate 12 biased together by a compression spring 16. A backing roller 19 has a peripheral ridge of arcuate section thereon which coacts with a recess on the drive roller 18 to upset the wall of the container during rotation to form a continuous inwardly directed projection at a predetermined distance from the extreme edge. The projection does not correspond in shape to the arcuate external groove and is preferably formed with a square shoulder upon which a closure plate 26 rests, Fig. 3. The backing roller 19 is carried on a pivoted arm 20 which may be manually or mechanically operated to move the roller 19 into engagement with the container against a spring 23. A similar machine is used to chamfer the extreme edge of the container. After inserting an electrical capacitor 25 in the container the closure plate 26 carrying terminal tags 28 and a neoprene sealing member 27 are seated on the internal projection. The extreme edge of the container is then turned over by an hydraulically operated die 32 while the container is located relative to the die by four sectional guides 31 engaging the previously-formed external groove. The accurate location of the container and a two-stage operation of the die 32 ensure that penetration of the neoprene seal is not excessive.

Abstract: 265,902. Siemens - Schuckertwerke Ges. Feb. 13, 1926, [Convention date]. Void [Published under Sect. 91 of the Acts]. Carding - engines.- In an arrangement for driving the cylinder of a carding-engine by an electric motor through a train of gears the gear is made capable of being disconnected to allow the cylinder to be driven slowly for grinding &c. The motor 1 drives the cylinder shaft 6 through the gears 4, 5 and may be made capable of sliding, or tipping on the bracket 2 so that the gear 4 is moved bodily away from the gear 5. The gear 5 may be loose on the shaft 6 and clutched thereto by a clutch 10 normally kept in engagement by a spring 15 and lever 11. When it is desired to disconnect the gear 5 a removable key 16 is inserted in the casing 14 to move the lever 11. The key carries a cross-pin 17 so that, when it is turned, the spring 15 cannot force it out. The drive for grinding &c. is taken from the pulley 9 on the motor shaft.
