Title: Improvements in or relating to guillotines and like cutting machines
IPC: B23D15/06
Filed: 1960-12-19
Abstract: 932,344. Guillotine cutting-machines. J. E. THOMPSON. Dec. 13, 1961 [Dec. 19, 1960], No. 43636/60. Class 31 (1). The movement of the work-feeding block 9 of a guillotine machine as it feeds the work along a table 2 to a cutting blade 6 is arranged to effect rotation of a shaft 14 which is mounted, together with the blade 6, in a superstructure 3 and serves to actuate means for indicating the position of the block on the table and/or means for controlling the operation of the machine according to a set programme, the shaft 14 being rotatable independently of the drive means for the block 9. The shaft 14, which is mounted in bearings 15 and carries a sprocket 12 at its lower end for connection via a chain 11 to the block, is spring-loaded in such a manner that it rotates under the influence of the spring upon the forward movement of the block as the latter is driven by a lead-screw 7. A steel tape 24, driven by a drum 23 mounted on the shaft and calibrated to correspond with the distance of the block 9 from the blade 6, is arranged for direct viewing through a window 22. A glass disc 16 also mounted on the shaft and having calibrations near its circumference which correspond with those on the tape serves to give a magnified reading at a ground glass screen 21 through the means of an optical system which consists of a light source 17, lenses 18, 19 and mirror 20. Control of the machine is attained by arranging an adjustable photo-electric cell to scan a paper disc which has reference lines corresponding to the desired programme, the disc being either mounted at the upper end of the shaft 14 or on the end of a shaft which is arranged to be driven through bevel gears 26, 27 as shown ; the gears are spring-loaded to avoid backlash. In operation, the work is placed on the table 2 between a clamping block 5 and the block 9. A guard for the machine is then lowered to initiate forward movement of the block 9 by contacting a switch which starts the lead-screw motor. When a reference mark on the paper disc is detected by the photo-electric cell, a circuit is operated to stop the motor and apply the clamp 5. When the clamp is in its lowest position it operates a switch to actuate the blade 6 and when the latter has made its cut, it operates a relay to reverse the movement of the blade and clamp. Return of the clamp operates a switch to restart the lead-screw to recommence the cycle of operations. A second photo-electric cell will, when the last cut of a programme has been completed, detect a stop mark on the paper disc for the purpose of initiating the return of the block 9. Instead of drawing reference lines with a scriber, the paper disc may be marked by a pair of spark electrodes which are mounted one on each side of the disc and actuated by a push-button each time the block 9 is positioned when setting the programme. The machine may incorporate the linkage system described in Specification 932,343 for operation of the blade and clamp.

Title: Manufacture of pure formaldehyde
IPC: C07C/
Filed: 1959-12-28
Abstract: Pure formaldehyde is produced by the thermal splitting of a semi-formal into formaldehyde and alcohol, by heating a semi-formal derived from formaldehyde and an alcohol which melts below 100 DEG C. and boils above 100 DEG C., washing the mixture of vapours formed with a hydrocarbon, as a first auxiliary liquid, which has a good solvent power for the alcohol split off from the semi-formal and little or no solvent power for the formaldehyde and has a boiling point below that of the alcohol, passing the remaining vapours through a condenser and washing them with another hydrocarbon, as a second auxiliary liquid, which is a good solvent for the alcohol and has little or no solvent power for the formaldehyde but has a boiling-point above that of the alcohol the two auxiliary liquids not forming azeotropic mixtures with the alcohol and having boiling points which enable them to be readily separated from the alcohol by distillation.  Suitable alcohol components of the semi-formals are, for example, cyclohexanol, methylcyclohexanols, butane-diol-1,4, pentanols, hexanols and octanols.  Suitable first auxiliary liquids are hydrocarbons boiling in the range 180-350 DEG C.  Suitable second auxiliary liquids are hydrocarbons and hydrocarbon mixtures boiling in the range 80-200 DEG C.  The process may be carried out continuously or discontinuously.

Abstract: 1,077,000. Coffee percolators; cooking vessels. PROCTOR-SILEX CORPORATION. Oct. 30, 1964 [July 31, 1964], No. 44304/64. Headings A4A and A4D. [Also in Division H2] In an electric percolator, a container 14 is secured in sealing relationship with a base 10 by means of a latch member 79. On raising lever 85, the latch member 79 is retracted upwardly by a leaf spring to permit container 14 to be lifted off the base. The container is preferably of heatresisting glass. Lid 16 has a clip 106 which supports coffee basket 18 and fountain tube 20 is gripped within tube 99 by spring 101. The lid is held down, resiliently to seat disc 93 in well 96, by catch 115 engaging the tip of latch member 79. Basket 18 is freed from the lid by depressing pushbutton 126 to open clip 106. Heaters 32, 33 are controlled by bi-metallic strip (146) responsive to the temperature in the upper part of well 96 and conductively connected. to flange 42 by bracket (145). Simmering heater 33 is shorted out through closed contacts (150) and (153) until strip (146) bends sufficiently to open them and connect the heaters in series. The temperature at which this occurs may be adjusted by rotating arm (161) to move rod (160) axially and displace contact (148). Overheating is prevented by a further bending of strip (146), which makes insulating post (155) operate strip (149) to open contacts (148) and (150) and de-energize the heaters and lamp (171). An additional bi-metallic strip (152), which is heated by the passage of current through it, delays re-closing of contacts (152) and (150), when strip (146) cools, until the temperature of the coffee has fallen well below boiling point. Lamps (170 and 171) are mounted below translucent disc 40 which is peripherally sealed to a rubber mounting ring 37 and a rubber sealing ring 53.
