Title: Improvements in apparatus for cutting substances into predetermined sizes
IPC: B26D1/00
Filed: 1934-12-31
Abstract: 449,555. Cutting and slicing machines. GIUSTI, T., 52, Pembroke Road, Islington, London. Dec. 31, 1934, No. 37324. [Class 5 (i)] [See also Group V] Slabs of material such as ice-cream, butter, or cake, are cut on a table by a vertically reciprocating set of knives comprising a main transverse knife and a number of knives at right angles thereto and adjustably spaced from one another. The material rests upon a board 6 which is slid intermittently over the table I by a member 5 which passes through slots in the table and is connected to spaced chains 7 which are tensioned by spring-loaded jockeys 36 and driven by a ratchet wheel 27 on the shaft 9. The cutting-members comprise a transverse knife 14 and knives 15 at right angles thereto secured in holders 16 slidably adjustable in slots 17. The knife assembly is slidable on vertical posts 12 and, when it is depressed by a pedal 29 which is connected to the knife assembly by rods 33, a roller 21 carried thereby engages an inclined surface 44 on an arm 20 pivoted to a stationary part 19 of the machine and connected by a pin and slot 25, 23 to a pawl-carrying lever 24 which thus imparts a feed movement to the ratchet wheel 27 and the chains 7 during the first part of the descent of the knives. The feed movement is regulated by adjusting the inclined surface 44 by a screw 46, and a stop 40 prevents the arm 20 from swinging too far under its own momentum. To prevent the material from rising with and sticking to the cutters, vertically adjustable scrapers 42, 43 are provided, the scrapers 42 passing between the cutters 15. The member 5 is prevented from passing beneath the cutters by a rod under the table carried by the chain lugs 4 which contacts with a lever 48a which holds the arm 20 against the returning action of the spring 39. The return of the member 5 is effected by lifting the pawl 28 and turning the handle 41. The board 6, as it is pushed over the end of the table 1 is supported by a frame 5b which is slidable in grooves in the table 1 and is pushed forward by the lugs 4. The material is guided at its sides by L-sectioned adjustable guides.

Abstract: 854,036. Discharge tubes. GENERAL ELECTRIC CO. Nov. 21, 1958 [Nov. 25, 1957], No. 37553/58. Class 39(1). In a method of converting thermal energy to electrical energy with a device including a pair of electrode surfaces having substantially different work functions and supported in closely spaced and insulated relation within a vacuum-tight enclosure, heat energy 14 is supplied to the electrode 1 having the higher work function to produce a copious supply of electrons, the electrode 2 having the lower work function is maintained at a temperature several hundred degrees Kelvin e.g. 700K. lower than electrode 1, and positive ions are supplied to the space between the electrodes to substantially neutralize the space charge therebetween. As shown a reservoir 7 of readily vapourizable metal, caesium, potassium or rubidium, is located opposite the inlet 10 to the cooling jacket 8. The metal vapour provides a complete coating on electrode 2, of oxidised silver molybdenum, nickel, tantalum, iron or stainless steel, and a partial coating on electrode 1 of molybdenum, tungsten, tantalum or nickel, whereby the work function of electrode 2 is less than that of electrode 1. The positive ions may be produced by the uncoated portion of the emitted electrode or by means of a tungsten filament, heated with direct current, and extending across the diameter of the device between electrodes 1 and 2, and spaced a distance of À025 to À05 mm. from each. However, if desired the positive ions may be injected into the device from an external source. The heat energy required to maintain electrode 1 at a temperature of 1800K. may be derived from a nuclear reactor or solar energy system. In an alternative arrangement an inner cylindrical electrode 19, Fig. 4, may be heated by nuclear reaction using uranium oxide fuel or may be open-ended, the heating medium being passed therethrough.
