Title: Slicing machine for household use
IPC: B26D1/36
Filed: 1948-06-30
Abstract: 651,920. Slicing-machines. JORGENSEN, A. G. June 30, 1948, No. 17679. Convention date, May 27, 1947. [Class 5(i)] Relates to machines for slicing vegetables in which the material to be sliced is fed through a funnel 21 to a rotating disc carrying adjustable knives around the circumference. According to the invention, flexible knives 9 are fixed to the disc 7 at the forward cutting edge 19 and held to the disc at the rear end by pins 4 slidable in slots 8 in the disc so that the radial distance between the cutting edge of a knife and the rear of the preceding knife can be varied to adjust the thickness of the slices. The pins 4 project into milled slots 2 in an annular disc 1 rotatable relative to the first disc to effect adjustment of the pins. Brackets 5 fitted to disc 7 and attached to the knives hold the knives in line with the periphery of the disc 1. To adjust the knives a stop 12 moving in a recess 18 in the rear wall 14 of the casing 20 is brought into engagement with a pin 3 projecting from the disc 1. Disc 1 is thus held stationary while disc 7 is rotated to give the required thickness of slice. The stop 12 is then moved out of engagement so that the discs can be rotated together by a crank handle 13 on a driving shaft 6.

Abstract: 655,384. Range-finders. KALART CO., Inc. July 9, 1947, No. 18156. Convention date, Dec. 28, 1943. [Classes 97 (i) and 98 (i)] In a range-finder of the type in which incident light travels from an object to a first reflector of the range-finder directly and via a second reflector whereby two images of the object can be seen, an optical detour is introduced into the direct beam substantially to equalize the two light paths and so to produce two images of substantially the same size. As shown in Fig. 2, light from the object 3 which is aligned with the line of vision of the eye 4 reaches a stationary reflector 5 via a pivoted reflector 2 and via an optical detour comprising reflectors 6 and 7 and semi-transparent reflector 8, the latter preferably located mid-way between reflectors 2 and 5. Prisms may replace the reflectors. As shown in Fig. 3, the fixed reflectors 9, 11, 15, 17 correspond to reflectors 5, 8, 7, 6 of Fig. 2, and the pivoted reflector 13 is connected to a lever 28 having a pin 27 pressed by a spring 33 against the wedge surface 26 of a bar 25 held by a spring 31 against a fixed pin 30 and pivoted to a lever 24.

Abstract: 460,949. Coin-freed article-delivery apparatus. WISTOFT, S. June 30, 1936, No. 18186. Convention date, April 23. [Class 27] Articles stored in separate compartments.- In a coin-freed vending-machine having a number of goods-containing compartments access to which is obtained through a door released after the insertion of a coin, the compartments are divided into smaller spaces, each containing goods, access to the inner small space being had by the purchaser when the door is closed after the completion of a purchase from the outer space and the insertion of another coin. Each compartment comprises top and bottom walls 1, 2 and is closed by a door 3 hinged at 4 and having an exterior handle 5. The door is connected by links 17, 18 to an axle 19 carrying a disc 20 an abutment 21 on which engages a pin 22 on a vertical rod 23. The rod 23 in known manner is normally locked and cannot be moved upwards to allow the door to be opened unless a coin has been inserted. The compartment is divided into two spaces 7, 8 by an inclined plate 6 having its upper edge resting against a shoulder 9 on the top wall 1 and its lower edge resting, by means of a shoe 10, on the bottom wall 2. A hook 11 abuts against a shoulder 12 on one arm 13 of a bell-crank lever pivoted at 14 and having its other arm 15 connected to a slotted link 16. The shoulder 12 normally prevents the plate from falling down under the weight of goods in the space 8. A pin 24 on the disc 20 engages in the slot 25 in the link 16, this slot having on its upper side an abutment 25a. When the door 3 is opened to obtain goods from the space 7, the pin 24 travels in the slot 25 and, during the closing of the door, contacts with the upper side of the slot and engages the abutment 25a thereby rocking the lever 13, 14 to release the hook 11 and allow the plate 6 to fall. When another coin is inserted and the door again opened, the goods in the space 8 are accessible. Filling storage compartments.-A rod 26 with shoulders 27 is provided for raising the links 16 to allow the plate 6 to be manipulated into its inclined position when the compartments are being filled with goods.

[Also in Group VII] In an automatic machine for removing shoes shaped on lasts, the lasts are fixed to bars 11 by members 30, the bars being held rigidly in carriers 14 on chains 12 which rotate over sprockets 15, 16, 17 mounted on shafts 18, 19, 20 and driven by motor 6. The lasts are guided by interior lateral guides 9 and 10 past an unshoeing mechanism 43 where the shoes are partly removed by a lever 45, and completely removed by claw 56 of lever 46, both levers being mounted on bifurcated lever 44 on transverse support 8, after. which the shoes fall on to conveyer belt 64 and are removed to collecting chamber 65 placed under a hatch door 70 with pneumatic means 71 of operation. Shoes still hanging from the lasts despite previous operations, are released by the action of hinged tray 90 deflected by bar 11 against the action of spring 91. The empty lasts 35 are then removed by means of arms 85 and 86 of hammer 83, raised by abutment of bars 11 against lever 84. The detached lasts fall via ramp 72 on to conveyer belt 75 where they are taken to a collecting chamber. The bars 11 on reaching the point 61 where lug 59 of the guides 9 and 10 is interrupted to the point 61<1>, are released and fall into chamber 79 ready for reuse. The hatch doors of the various chambers are controlled by distributing valves interposed between the feed duct of the pneumatic means and the respective operating means each value being operatively linked with a solenoid.

Abstract: The invention comprises compounds of the general formula <FORM:0916101/IV (b)/1> (wherein Hal represents a halogen atom, R1 represents a C1-5 alkyl group and R2 represents hydrogen or a C1-5 alkyl group) and the preparation thereof by reacting a compound of the general formula <FORM:0916101/IV (b)/2> (wherein X represents chlorine or bromine) or <FORM:0916101/IV (b)/3> (wherein Y represents hydrogen or a methyl or ethyl group) with a compound of the general formula R2-NH2  IV or by reacting a compound of the general formula <FORM:0916101/IV (b)/4> (wherein Z represents chlorine or bromine) with a compound of the general formula R1-NH2  VI or (when R1 and R2 are identical) reacting a compound of the general formula <FORM:0916101/IV (b)/5> with at least two molecular proportions of a compound VI.  The products are pharmaceutically useful on account of their diuretic, saluretic and hypotensive activity.  Lactones of the general formulae II and VII are prepared by treating compounds III and VIII respectively with mineral acid halides.  Acids and esters of the general formula III are prepared by reacting compounds VIII with compounds VI under relatively mild conditions.  Lactams of the general formula V are prepared by nitrating 1-oxo-3-(p-halophenyl)-3-hydroxyisoindolines, reducing the nitration products, diazotizing the amino compounds and treating the diazonium salts with sulphur dioxide in the presence of copper chloride or bromide.  Sulphohalides of the general formula VIII are prepared by nitrating the 41-halo-2-carboxybenzophenones resulting from FriedelCrafts condensation of halobenzenes with phthalic anhydrides or phthalic acid ester halides, reducing the 41-halo-31-nitro-2-carboxybenzophenones so formed, diazotizing the resulting 31-amino compounds and decomposing the diazonium halides with sulphur dioxide in the presence of copper salts.
