IPC: D05B69/22
Filed: 1971-10-13
Abstract: 1375540 Sewing machines M SPIEGEL and M SPIEGEL 13 Oct 1971 [14 July 1970] 34211/70 Heading D1G [Also in Division F2] A machine, e.g. a sewing machine, comprises a driven element, which can be stopped in a predetermined position, driven by a motor M connected to a first input member 60 of a drive transmission by a coupling 44 releasable by means which also activate an auxiliary drive coupled to a second input member 74 of the drive transmission so as to contrive to drive the element until means 210 which indicate a predetermined position in which the element is to be stopped are detected by sensing means 208, 210 which operate to move a brake disc 218 movably connected to an output member of the drive to brake the transmission and also to disconnect the auxiliary drive. A treadle 14 is depressed to start the machine by operating coupling 44 to drive shaft 60 on which are mounted one-way bearings 66, 68 carrying a sleeve 64 on which is mounted pulley 62 which through belt 42 drives the sewing machine 10 at normal speed. When the treadle is released, coupling 44 is released and a control circuit is energised so that auxiliary drive shaft 200 driven by motor M operates through clutch 202 and speed reducer 204 to drive gear wheel 74, which is carried on a one way bearing mounted on sleeve 64, and hence pulley 42 and the machine 10 at a reduced speed of 200 r.p.m. At the same time plate 218 is attracted to plate 214 by electromagnets therein to slow down the machine. The machine then moves at reduced speed until a selected one of the two switches 206, 208 is traversed by magnet 210 when clutch 202 is disengaged and the brake 214, 218 is applied to stop the machine in the required position, i.e. needle up or needle down in the sewing machine shown. Lights 13, 15, 19 indicate the operation of various parts of the control circuit so that by using a module construction any part not operating may be readily detected and replaced. A switch bypassing the selected switch 206 or 208 may be provided which can operate coupling 202 to restart slow speed drive (indicated by light 15 going out). Instead of switches 206, 208 sensors activated by light from light emitting diodes may be used, Fig. 5 (not shown). Instead of taking the auxiliary drive from the main motor M, a second motor may be provided.

Title: Improvements in or relating to the production of vinyl esters
Inventor: BRACONIER FREDERIC FRANCOIS AL
IPC: B01J8/24
Filed: 1955-11-30
Abstract: Vinyl esters are prepared by reacting acetylene and a carboxylic acid using standard fluidized-bed technique, the catalyst, consisting of at least one metallic salt known to activate the reaction and which is capable of regeneration by combustion, being continuously removed from the reaction zone, a deposit of catalytic particles being formed at the lower end of the reactor acting as a substantially water-impermeable pad, regenerated by combustion and recycled to the reactor.  The rate of flow of reactants is greater than that which would permit complete reaction.  The catalyst is used as a powder, alone or on a support such as silica gel or clay.  The particle size may vary from 40-200 microns, 95 per cent of the particles being from 50-150 microns.  Zinc and cadmium silicates are the preferred catalysts.  The reactants may be used in stoichiometric proportions or one reactant, preferably the acetylene, may be in excess.  The gaseous mixture leaving the reaction zone is freed from entrained catalyst by, for example, cyclone separators, filters or electrical precipitators and cooled to condense the vinyl ester, the unreacted reactants being recycled to the reaction zone.  The vinyl ester is fractionally distilled to eliminate impurities, dissolved acetylene and unreacted acid, the last two being recycled.  The reaction temperature is generally 150-300 DEG  C.  The reaction zone is preferably surrounded by a cooling jacket.  Examples describe the preparation of vinyl acetate and vinyl butyrate, but the process is stated to be applicable generally to vaporizable, acyclic or cyclic, mono- or polycarboxylic, substituted or unsubstituted acids.

Title: Rotary crank press
IPC: B30B1/26
Filed: 1974-08-07
Abstract: 1460986 Converting rotary to reciprocating motion; eccentrics AIDA ENG KK 7 Aug 1974 [10 Aug 1973] 34759/74 Heading F2K In a mechanism for converting rotary motion to linear reciprocating motion, a driven shaft 1 rotating on a fixed axis Z has an integral eccentric portion la, engaged rotatably in an eccentric sleeve 2 which in turn is rotatably carried within a slider member 3, this slider member being constrained by guide means 4<SP>1</SP>, 4<SP>11</SP>, which permit reciprocating movement in a direction perpendicular to the shaft axis Z. The guide means may consist of integral side members 4 having faces 4<SP>1</SP>, 4<SP>11</SP> projecting from a bearing block 4a in which shaft 1 is journalled. In Fig. 1, centre B of the eccentric portion la is caused to orbit around a fixed centre A of shaft 1, while the centre C of the periphery of sleeve 2 is constrained to travel solely along the vertical centreline through A. Sleeve 2 is not driven in rotation by any means other than the "squeezing" action imposed on it between the eccentric portion la and the bore of slider 3. From an initial position as shown in Fig. 1, with centres A, B and C aligned upwards, the first 90 degrees of rotation of shaft 1 in the direction P induces a motion of sleeve 2 in direction Q, reversing to direction Q<SP>1</SP> during rotation from 90 degrees to 270 degrees, and reverting to direction Q from 270 degrees to 360 degrees, and centre C travels in direction X during shaft rotation from 0 degrees to 180 degrees, reversing to direction Y from 180 degrees to 360 degrees. In an alternative embodiment, Fig. 4(a), the centre A<SP>1</SP> of shaft 1 is located in a vertical plane laterally offset from the verti. cal plane through centre C. This modified motion provides a downward travel of centre C in direction X which may be prolonged over approximately 210 degrees of shaft rotation, with a faster return travel in direction Y to complete the cycle. A mechanism having either of the alternative embodiments may be incorporated in a press, in which the slider 3 may be formed integrally with the press ram member 10, Fig. 6 (not shown), or alternatively the slider 3 may be provided with a threaded bore carrying an adjusting screw 13 coupled to a separate press ram member 10, Fig. 8.
