Title: Drying material in vacuo by high frequency dielectric heating
IPC: H05B6/46
Filed: 1945-07-20
Abstract: 606,567. Dielectric heating in vacuum. COMMUNICATIONS PATENTS, Ltd., and STANLEY, E. C. July 20, 1945, No. 18578. [Class 39(iii)] A method of drying material in powder, granular, or tablet form (e.g. penicillin) under reduced pressure by subjecting it to a high frequency electrostatic field, with special precautions for preventing Geissler discharge in the vacuum. The material under treatment is arranged in a glass vessel between a pair of electrodes so that the amount of material occupies fully all the space between the electrodes, and it is stated that this prevents the high frequency field from extending into the surrounding space within the chamber and giving rise to Geissler discharge. Light sensitive and weight sensitive means are described whereby this condition may be observed and controlled to prevent the application of the high frequency field when insufficient material is present between the electrodes. Condensing means may be provided whereby the vapours from the material are collected during the heating operation.

Abstract: 1348316 Feeding sheets ING C OLIVETTI & C SpA 7 June 1971 [5 June 1970] 19289/71 Heading B8R A sheet feed device includes a sheet thickness feeler defining a gap, and means for receiving a standard sheet or sheets which adjusts the gap such that when a sheet or sheets thicker than the standard passes the feeler, a signal is produced. Sheets 8 may be separated by suction heads 24 from a pile on a table 7, raised in accordance with the height of the pile, and presented to the nip between a feed roller 41, e.g. of rubber, and pressure feed rollers 42, mounted in arms 44 rotatable about a shaft 46 and biased towards the roller 41, within limits set by a screw 51 and co-operating pin 49 of a crank arm 47 fixed to the shaft 46. The feeler is constituted by a roller 61 held in an arm fixed to the shaft 46 whilst the means for adjusting the feeler comprises an arm 84 fixed to shaft 46 and resting on a plate 88, a standard sheet being placed between this plate and a fixed plate 91. In operation, a crank arm (54) Fig. 1 (not shown) fixed to shaft 46 is rotated anticlockwise by a cam 58 before a sheet is presented to the feed rollers 42, these rollers together with the feeler roller 61, being thereby raised from the feed roller 41. As cam 58 continues to rotate it restores crank arm (54) to its original position thereby rotating shaft 46 clockwise until the arm 84 abuts the plate 88 housing a standard sheet. Thus the feeler roller 61 is maintained spaced from the roller 41 by a distance slightly greater than the standard sheet thickness whereas the feed rollers 42 are biased towards the roller 41 so as to feed the sheet 8 to the belts 32, rollers 33 and guides 34 of a registering table 26. When a sheet or sheets of greater than the standard thickness is fed, however, feeler roller 61 is rotated during its feed and activates an electromagnet 73 which moves a switch 81 to deflect the faulty sheet to a bin (80). An overlapping stream of sheets may be fed by the device.

[Also in Division E2] In a hook for coupling shackles 26, 27, ropes, rods, safety belts &c., a mousing slide 28 is urged by a spring 40 to narrow the guideway 256 into the hook portion 25a and prevent accidental release of the shackle 27 &c., but when a lever 29 is lifted, Fig. 7, about its pivot 34, a pin 35 on the lever depresses the slide 28 to clear the guideway. Raising of the lever 29 still further, as shown in broken lines in Fig. 7, causes the lever to eject the shackle 27, which can be reintroduced simply by forcing it into the guideway 25b to depress the slide 28 from the position shown in Fig. 3. The hook is made up of three plates 36, 37, 38, Fig. 4, held together by rivets 39 as shown in Figs. 3 and 7. The lever 29 may be operated remotely by a lanyard secured in a hole 62 in a finger plate 33. The lever 29 has a bight 60 in which can engage part of the cylindrical surface of a button 41 so as to be looked in the position of Fig. 3 until the button is depressed against a spring, Fig. 4, so that the lever edge can ride in a crescent-shaped recess 54 in the button face. The button can be kept depressed by rotating it until a side tongue 53 is detained behind a thick portion of the plate 36. The remote, lanyard control is then possible. In another embodiment, Figs. 12-17 (not shown), the mousing slide carries a row of teeth so that it can be lowered by raising a handle of square U shape to rotate two aligned stub-spindles journalled across the hook body and thereby rotate an intermediate member with three teeth which engage the slide teeth. The slide can be depressed directly, with a free rotation of the tooth-bearing member, independently of the handle. Two teeth on one stub spindle depress a lever for ejecting the load from the hook.
