Title: Rotary cutter
IPC: B27G13/10
Filed: 1960-06-03
Abstract: 935,748. Milling cutters. L. OPPOLD. June 3, 1960 [June 5, 1959], No. 19743/60. Class 83 (3). [Also in Group XXIII] A rotary cutter comprises a disc 6 formed with one or more peripheral recesses 10, 11 within each of which is located a cutter blade 15 having its cutting edge 21 disposed outwardly of the periphery of the disc and a locking plate 16 which engages the back face of the blade, abuts a projection 18 on said face, and has rearwardly-extending lugs 19, 20 engaging flanges 7, 8 or projections 7a, 8a formed on the respective sides of the disc at its periphery. Each blade and locking plate are clamped in the recess by a wedge 12 adjustable outwardly by a screw 13. When re-grinding the blade, the plate 16 is turned through 180 degrees so that the lower inclined end face 23 has the same amount removed as the blade face 22 and, when the plate is returned to its original position, the distance of the cutting edge 21 from the projections 19, 20 and the projection of the cutting edge from the periphery of the disc are therefore unchanged. If desired, the lugs 19, 20 may additionally project forwardly from the plate 16 to engage in channel members on the back face of the blade or embrace the side edges of the blade. Accurate location of the blade may be effected by providing a pin-andslot or projection-and-groove interengagement between the blade and plate 16. To prevent injury to the hand of an operator, a guard plate 35 may be clamped between the wedge 12 and forward wall of the recess.

Patent GB-829825-A (GB)
Title: Casting machine for production of regenerated cellulose films
IPC: B29C48/03
Filed: 1956-06-27
Abstract: <PICT:0829825/IV (a)/1> <PICT:0829825/IV (a)/2> A film-casting machine having a delivery pump and an extrusion nozzle is provided with a pulse-dampening feed hose, a first relatively short rigid tube, one end of which communicates with and is connected to the pump and the other end of which communicates with and is connected to the hose, and a second relatively short rigid tube, one end of which communicates with and is connected to the nozzle and the other end of which communicates with and is connected to the hose.  The hose is characterized by a first flexible tube of resilient material and a second flexible tube spaced from and enclosing the first flexible tube in an air-tight manner, the second flexible tube being connected to the rigid tubes in such a manner as to provide a gas space between the first and second flexible tubes, and a gas inlet is located in the wall of the outer flexible tube in such a manner that this inlet is closed by the inner flexible tube when the latter is expanded by the flow of film-forming liquid therethrough, thereby causing gas to be trapped in the space between the flexible tubes beyond the gas inlet in the direction of flow of the liquid.  As shown, the feed hose includes a resilient inner tube 31 coaxially disposed within a reinforced outer tube 33 of greater diameter so as to provide an air space 35 between these tubes when they are in a relaxed condition. At its inlet and outlet ends the tube 31 is connected by band clamps 37 to the reduced portions 39 of the relatively short rigid tubes 41. The outer tube 33 is similarly connected at its opposite ends to the enlarged portions 43 of the rigid tubes 41 by means of band clamps 45.  Adjacent the inlet end of the feed hose a short tube 49 passes through the outer hose 33 and is secured thereto in a gas-tight manner by flange 50, washer 51 and nut 53.  After the castingmachine is shut down and spinning solution (such as viscose) is no longer pumped under pressure through the feed hose, the air inlet tube 49 admits air into the space 35 and thus the inner tube 31 is in its untensioned or collapsed position under atmospheric pressure.  When the pumping of the spinning solution through the feed hose is resumed, the resulting pressure in the flexible inner tube 31 causes the tube to expand and to engage with the inner surface of the outer tube 33 and with the inner end of the tube 49 and thus prevents escape of air therethrough. Once the tube 49 is closed, the progressive movement of the liquid through the inner tube 31 effects a continuing expansion along its length, thus forcing the air trapped in the space 35 to travel towards the air space 47 at the outlet end of the feed hose, where it functions to dampen pump pulsations during the normal period of the film-casting operation.  Lack of uniformity of thickness in the film being cast is thereby reduced.

Filed: 1937-07-19
Abstract: 501,052. Carpet-sweepers. WAGNER MFG. CO., E. R. July 19, 1937, No. 19968. Convention date, July 31, 1936. [Class 138 (i)] In a carpet-sweeper comprising a casing supported by one or more pairs of floor wheels the stub axle of each of which is secured to an arm mounted for limited swinging and longitudinal sliding movement under the action of a spring which presses the floor wheels against the brush pulley, the spring is connected to the arm and is so constructed and arranged that it offers a stiff resistance to the longitudinal movement of the arm in the direction separating the wheel and pulley while it presents a relatively light resistance to vertical swinging movement of the arm. In the construction shown in Fig. 2, each floor wheel 12 is mounted on a stub axle 14 which is fastened to an arm 15. The arm has a pin-and-slot engagement with the end wall 1 of the casing and the pivotal movement of the arm,is limited by an outwardly-displaced poition 18 of a bracket plate 16 secured to the end wall. The floor wheels are pressed against the brush pulley 31 by a spring 21 of the form shown. The brush pulley is mounted at each end on a trunnion 39, Fig. 4, which is fixed to a strip 40. The strip 40 is supported for vertical sliding movement in a guideway formed by displacing inwardly a lower portion of a metal end plate 7 and displacing out-. wardly an upper portion of the plate, a slot being formed between the two portions. The strip 40 is pressed downwardly by means of a spring 47. In a modification shown in Fig. 10, the brush trunnion 92 is carried by a horizontal resilient strip 89 having hooked ends 90 extending through slots 91 in the end plate 86. The ends 90 are engaged by the ends of a spring 93. The Specification as open to inspection under Sect 91 comprises also an arrangement in which two brush-clearing combs 56, Fig. 7 (Cancelled), are pivotally mounted near the upper part of the brush. Dust-pans 51 are held normally in closed position by means of a spring 53. The floor wheels may be pressed towards the brush pulley by a spring at each end of the casing, the ends of the spring engaging in notches formed in links which are pivoted on the stub axles of the wheels.

Abstract: 1504321 Spring applied, pressure released brake systems POCLAIN 13 May 1975 [14 May 1974] 20155/75 Heading F2F A system for controlling brake release of a reversible hydraulic motor 21 which may be mounted on the wheel of a vehicle or on the winding drum of a winch, comprises a brake shoe 18b held against the output shaft of the motor by spring 20b mounted in brake release jack 15b. The feed both to chamber 46b of jack 15b to release the brake and to the motor 21 is controlled by distributers 1b, 2b, 3b and 4b, the former (1b) being actuated by handle 14b and 2b, 3b and 4b by primary jacks 5b, 6b and 7b and returned by secondary jacks 8b, 9b and 10b. The motor is selectively fed from tank 24 by pump 22 via motor feed return lines 28, 29 and the jack 15b is fed by pump 55 through distributers 3b and 4b. Flow from the motor passes to either of distributers 3b or 4b through bleed pipes 40 or 44, having constrictions 41 and 45 respectively, according to the direction of rotation of motor 21. Release sequence.-Operation of handle 14b allows flow through distributer 1b from pump 22 to motor 21, the supply pressure in line 28 causes switching of distributers 4b and 3b (the latter being actuated by flow via distributer 2b to line 48), through jacks 7b and 6b respectively, which as shown in the figure allows flow from pump 55 through line 57, distributers 3b and 4b in that order to jack 15b causing brake release as shown. Using handle 14b the distributer 1b may be returned to its centre position (as shown in Fig. 2) cutting off supply to the motor and causing return of distributers 3b, 4b to cut-off the supply to the brake such that it is re-applied by spring 20b, or the regulator 1b may be actuated to its right hand position which causes reversal of the flow direction and subsequent brake release in a manner corresponding to the above.

Abstract: 1,002,838. Labels. R. C. MALBY. May 12, 1964 [May 21, 1963; April 29, 1964], Nos. 20201/63 and 17794/64. Heading B8F. [Also in Division B6] In a method of producing sheets of labels adhesively attached to a backing sheet for subsequent removal, the labels are formed by etching away the separating regions from a parent sheet of material which is provided with an etching resist in the label regions and constituting part of the finished labels. In one method, the labels are formed from a sheet 1, Fig. 3, of anodized aluminium or aluminium alloy impregnated with coloured dyes to form the label markings. The faces of the label regions are first covered with temporary masks 4, Fig. 4, of water-insoluble ink, paint or lacquer, resistant to acid attack, so that the unmasked anodized surfaces 2, 2a, in the separating regions may be removed by etching with hydrofluoric acid leaving exposed areas of aluminium. The temporary mask 4 is then removed by a solvent and the sheet 1 attached to a backing sheet 5, Fig. 7. The exposed areas of aluminium are then removed by a further etchant, such as ferric chloride, which does not attack the anodized surfaces 2 of the label face and leaves the separate labels 6, Fig. 10, attached to the backing sheet 5. In a modification the parent sheet of metal, plastic or other material may be coated with ink, paint of lacquer in the label face regions only and overprinted. The coating acts as an etching mask so that the parent sheet may be attached to a backing sheet 5 and a single etching operation carried out to separate the labels. Fixing holes and other openings may be formed in the labels during the etching processes.

Title: Emetine derivatives and their preparation
Inventor: RITCHIE ALEXANDER CRAWFORD
IPC: C07D455/08
Filed: 1960-06-09
Abstract: The invention comprises N-substituted derivatives of 1-emetine having the general formula <FORM:0977788/C1/1> (wherein R represents an unsubstituted alkyl, hydroxyalkyl, or esterified hydroxyalkyl group, the N-alkyl portion of which contains 2 to 7 carbon atoms) their non-toxic acid addition salts, particularly the mono- and di-hydrochlorides, hydrobromides, hydroiodides, sulphates, nitrates, citrates and tartrates, also addition complexes with bismuth halides also processes for their preparation (a) by N-alkylating l-emetine to introduce an N-alkyl, N-hydroxyalkyl or N-(esterified hydroxyalkyl) group at the 21-position; (b) by reacting a compound of the general formula <FORM:0977788/C1/2> (wherein R11 is an alkyl or hydroxyalkyl group of from 1 to 7 carbon atoms) in one or more stages with reagents serving to reduce a ketonic carbonyl group to a methylene group.  The principal methods for process (a) are (i) reaction of l-emetine with a functional derivative of an acid R1COOH (R1 is alkyl), and then reduction of the carbonyl group of the resulting amide, e.g. with complex metal hydrides; (ii) reaction of l-emetine with a vinyl ketone CH2:CHCOR11 (R11 being alkyl of from one to four atoms), followed by reduction of the carbonyl group in the resulting N-oxoalkyl compound, e.g. with hydrazine and alkali, or by conversion to the ethylene thioketal or benzylmercaptol derivative followed by reduction with a Raney metal, or, if a hydroxyalkyl compound is required by reduction of the carbonyl group with a complex metal hydride.  The methods for process (b) involve direct reduction with hydrazine and alkali, or reduction of the thioketal derivative e.g. with a Raney metal. The compounds of second general formula above are themselves prepared by reduction of compounds of the formula <FORM:0977788/C1/3> R11 is alkyl, hydroxyalkyl or oxoalkyl with a metal/ammonia or metal/amine reducing system followed by isomerization of the 3b -acetyl compound obtained. Any methoxyl groups that are converted to hydroxyl during the processes are remethylated, e.g. using a phenyl trimethylammonium salt.  The invention is illustrated by 11 detailed examples. Specifications 960,181 and 960,182 also are referred to.
