Title: A potato slicing machine
IPC: B26D1/29
Filed: 1949-12-14
Abstract: 712,521. Slicing potatoes. BROOKS, E., and TWEEDY & CO., Ltd., G. March 14, 1951 [Dec. 14, 1949], No. 32045/49. Class 5 (1) In a slicing machine with a radial cutter 23 projecting from an opening in a rotated disc 19, the slice thickness is determined by an adjustable insert 26 against which a potato is pressed located in the opening of the disc. In operation a potato dropped through the opening in a feed tube 6 is pressed towards one or more radial knives 23 by a plunger 7 pressed in by a hard knob 8a. The knives 23 which may be straight or corrugated cut off correspondingly shaped slices, which fall down to a hinged shoot 56. The knives 23 are mounted to project radially or tangentially from a rotated disc 19 which rotates across the previously cut face of the potato. The slice thickness is determined by the amount of projection or by the screw adjustment in or out of an auxiliary plate or insert 26 against which the potato is hand pressed. The insert 26 may have a corrugated surface 27 to match a corrugated knife. If the insert is removed altogether the potato is cut into scallops. The feed tube 6 is mounted at one side of the flat hinged cover 5 closing the chamber 4 containing the cutting disc 19 which is belt driven from an electric motor 15. The disc 19 is held on its driving shaft 10 by an adjusting screw 22. One half of the inneredge of the feed tube 6 may be corrugated or serrated to co-operate with the corrugations 27 on the insert 26 to ensure that the cutting plate is combed after each revolution and to ensure that all the potato is cut and ejected. The back of the rotary knife carrying plate 19 may have a projection to sweep and direct the slices into the shoot 56.

Title: Improvements in and relating to methods of fabricating sealed glass envelopes
IPC: H01J5/26
Filed: 1949-12-14
Abstract: 671,854. Glass. BRITISH THOMSONHOUSTON CO., Ltd. Dec. 14, 1949 [Dec. 24, 1948], No. 32112/49. Class 56. [Also in Group XL (a)] In the method of sealing a closure member to the glass envelope of an electric discharge device by induction heating of an interposed metal ring, residual compressive strain is introduced into the closure member during its manufacture, and disturbance of this strain by overheating is avoided by arranging the ring to have a line contact only with a beaded rim on the closure member. The residual strain is deliberately set up during the manufacture of the closure 11 by differential cooling; after it has been formed in a mould, one half of the mould is removed and an impinging jet of air 28 causes the outer surface of the glass 11 to cool more quickly than the inner surface which is still in contact with the other half 25 of the mould, so producing the desired condition of compressive strain.

Title: Cathodochromic display tube
IPC: H01J29/14
Filed: 1971-07-08
Abstract: 1360835 Uses of photochromism RCA CORPORATION 8 July 1971 [8 Oct 1970 (2)] 32239/71 Heading C4S [Also in Division H1] A cathodochromic display tube has a target of cathodochromic material 10 colourable by electron impingement with a coloration having an optically reversible component and an optically irreversible component, wherein the target is exposed to an electron beam which is modulated and simultaneously scanned to provide a visible coloration pattern means being included to suppress, at least a portion of the optically reversible component only. Suppression may be by radiation of erasing wavelength, by heating to below the total erase temperature, e.g. by infra-red radiation from an external or internal source or electrical resistance heating such as a thin metal or indium oxide film 20 on mica sheet 22 and connected to heating circuit 15 or by electron bombardment (e.g. the electron beam with or without additional heating). Gun electrode 30 may be connected to a conductive wall coating on the tube envelope 14. The cathodochromic material may be sodalite (e.g. Na 8 Al 6 Si 6 O 24 Cl 2  or with Br-, I-, OH- and SO<SP>2-</SP> 4  substitutions) which is not normally cathodromic until heat reduced in a hydrogen atmosphere. Br and Cl substitutions produce absorption bands of 5550Š and 5250A respectively. The optically reversible coloration usually saturation at contrast ratios of 2 to 3 to 1 (Curve A, Fig. 2, not shown) while the irreversible components in some bromine and chlorine sodalites continues to rise (Curve B). The latter component may be erased at 200 to 300‹ C. and Br sodalite is preferred, having an induced absorption spectrum close to the eye sensitivity curve. 100 to 150‹ C. is the temperature for most sodalite materials at which no optically reversible component is present. Fig. 4 (not shown) displays exposure required for a given contrast ratio and beam current with screen voltage as variable. Sensitivity to beam current is indicated as a heating effect, the sensitivity of the optically reversible mode decreasing with increasing current, while thermal erase sensitivity first increases and then decreases. In Fig. 5 (not shown), heating to higher temperatures than curve (2), reduces contrast ratio as in curves (3) and (4). Poor fidelity indicated by the non linear plot of Fig. 3 (not shown). The γ may be adjusted by circuitry in some cases, or by suppressing the optically reversible component with heat. In a 1/30 sec. TV scan the image from a 100 Áa beam is heated to 300‹ C. between seams to erase, 2 sec being required for erasure. Prior to further writing, cooling may be to an intermediate partial erase temperature.

[Classes 80 (i) and 80 (ii)] Means for locking a displaceable member, such as a toothed wheel slidable on a shaft, in either of two positions comprises a set of engagement members, such as balls, which are in two groups, one group serving for locking the wheel to the shaft, and the other serving to couple the wheel with a sliding member by which it is displaced. The wheel 2, Fig. 1, is splined on its shaft 1, and its movement is limited by shoulders 5, 5'. The hub 3 of the wheel has apertures containing balls 7, Fig. 5, which in intermediate positions of the wheel rest on the splines of the shaft. In the extreme positions, one or another group of the balls moves into recesses 8, 8' in the splines, so as to lock the wheel. A sliding collar 9 splined on the hub 3 has in its inner surface a groove 11, Fig. 3, which can accommodate the balls. The group of balls which has not moved inwards couples the wheel to the collar 9, which is operated by means such as a fork 14. When one set of balls moves inwards, the other set can move into lateral recesses 12, 12' in the walls of the groove 11. The collar 9 is thereby permitted to pass over the balls that have moved inwards, so as to lock them in position.
