Abstract: 996,318. Threshing machines. G. CLAAS, and R. CLAAS. Sept. 26, 1963, No. 37987/63. Heading A1F. [Also in Division F1] Apparatus for cleaning grain comprises a screen and a drum-type blower having an axial air inlet and a tangential air outlet, a number of jointly adjustable members being uniformly distributed about the air inflow aperture so as to form an adjustable diaphragm bounding the aperture and giving it an approximately circular profile. In the case of a winnowing blower for a threshing machine or a combine harvester, the air flow can thus be adjusted to suit the harvesting conditions. The casing 25, Fig. 4, of a winnowing blower comprises an axial inlet at each end, each inlet being adjustable in size by means of overlapping pipe segments 36 each of which is fixed at one end to one of a number of overlapping leaves 35. The leaves 35 are each pivotable about a pin and are interconnected by links 32 so that they can be moved in unison by means of a control bar 34 to cause the pipe segments 36, which are of resiliently deformable material such as plastics or sheet metal, to overlap to a greater extent and reduce the inlet diameter, as shown in Fig. 6. Each pipe segment may alternatively comprise two or more members hingedly connected together along axes extending parallel to the impeller shaft. As a further alternative, pipe segments similar to the segments 36 may form a pipe which is frusto-conical when relaxed, the pipe being opened to a greater or less degree by inserting a ring. The pipe may be omitted, each inlet opening then being formed by leaves 35 only, which form an adjustable iris diaphragm. The links 32 may be replaced by a rotary element acting on the individual adjustable inletforming members by means of rocking levers or curved guides. Instead of being pivoted, the adjustable members may be slidable.

Title: Beverage brewing and dispensing apparatus
IPC: A47J31/00
Filed: 1963-12-31
Abstract: 1,072,351. Coffee making apparatus. CORY CORPORATION. Dec. 31, 1963 [Dec. 31, 1962], No. 38372/63. Heading A4D. In an apparatus for preparing, storing and dispensing coffee into jugs or like containers for further distribution, the beverage preparing and storing means are duplicated so that one may be recharged with coffee grounds, while the grounds in the other are being infused or the coffee is being dispensed. After recharging brewing chamber 34 with coffee grounds and replacing it, selector arm 65 is swung by handle 17 about a vertical axis to prepare one means for infusion and to permit the other means to be recharged. The arm 65 operates pivoted lever 67 to adjust valve 60 to supply hot water to chamber inlet 64 and to effect sealing between the inlet and the lid of chamber 34. A solenoid controlled valve (259) is operated, on depressing start button (19), to deliver cold water to thermostatically controlled boilers 54 and 55. Hot water is thereby displaced from the boilers and flows through pipes 56, 59 and 63 to inlet 64 of chamber 34. At any time, handle 17 may be twisted about its axis, to adjust valve 57 and operate switch 257 (controlling valve 259), to divert a flow of hot water to outlet 29. Disabling switches (184, 191) in the circuit of coil (259a) prevent actuation of the valve (259), if the chamber 34 or coffee storage tank 38 are out of position. Switch (191) is also responsive to actuation by a float (199) in tank 38, which must be in the tank empty position before valve (259) can be operated. The hot water supplied through inlet 64 passes through to the bottom of the chamber and wells up through to coffee grounds to be discharged at lip 143 after passing through a filter panel in the chamber lid. The coffee runs from lip 143 into tank 38. Tank 38 is provided with a thermostatically controlled heater (233) in mounting 234 which is initially energized through a holding circuit for a start-button operated relay, in parallel with the start-button contacts (19a, b). When the tank 38 is full, float operated switch (191) is actuated to break the holding circuit, de-energize coils (259a and 261) (thus terminating infusion and providing an alternative path of energization of heater 233) and allow a circuit to be completed, through dispensing button contacts (24a, b), which can operate a solenoid (117) controlling a plug valve (130) sealing a hole (140) in the bottom to tank 38. The valve (130) can be closed manually in an emergency and solenoid (117) is further disabled, electrically, by a feeler device 266 detecting the presence of a jug 13 beneath hole (140). The weight of a partially filled jug 13, on plate 12, operates a switch 268 to energize a lowwattage heater in the plate. Visual indicators show the levels of coffee in tanks 33 and 34 and signal lamps indicate the preparative step required. Both brewing chambers 33 and 34 may be removed when handle 17 is in its central position.

Abstract: 999,469. Transistor logic circuits. SOC. NOUVELLE D'ELECTRONIQUE ET DE LA RADIO-INDUSTRIE. Oct. 12, 1962 [Oct. 20, 1961], No. 38732/62. Heading H3T. A minority logic circuit, Fig. 1, comprises two transistors of opposite conductivity types having their base electrodes connected together and through respective substantially equal resistors to an odd plurality of input terminals, and their collector electrodes connected through respective load resistors to respective power - supply sources and to each other through two equal resistors the junction point of which is connected to an output terminal. A majority of positive inputs (i.e. a minority of negative inputs) at terminals A, B, C gives rise to a negative output at terminal S, similarly a minority of positive inputs gives rise to a positive output. Fig. 3 shows a three-input minority-logic circuit I followed by five-input minority-logic circuit II, the output of circuit I providing two of the inputs for circuit II through separate resistors Be. The signals applied to terminals x, y predetermine the operation of the circuit upon inputs A, B. Thus if x, y are both given positive inputs corresponding to " 0," the circuit operates to indicate equality between A and B. If both x, y are given inputs corresponding to "I," the circuit operates to indicate inequality between A and B, i.e. it functions as an exclusive-OR circuit. If x=0 and y 1, a zero output is obtained for all values of A and B, while if x=1 and y=O, a unity output is obtained for all values of A and B.

Title: Lithographic plates and method of making such plates
IPC: G03G13/28
Filed: 1965-09-21
Abstract: 1,129,366. Photographic processes for producing lithographic plates. MINNESOTA MINING & MFG. CO. Sept.21, 1965 [Sept. 21, 1964], No.38810/65. Headings G2C and G2M. An image-receiving material capable of conversion to a lithographic plate comprises a backing having an oleophilic surface coated a liquid permeable hydrophilic layer containing a reduction promoter and this layer becoming friable and removable on reduction of metal ions to the metal; premature reduction of metal ions being prevented by either (i) limiting the reduction promoter to the oelophilic/hydrophilic interface and leaving the upper part of hydrophilic layer free of reduction promoter or (ii) adding a humectant such as glycerin to the layer. Lithographic plates are produced by selectively permeating a metal salt through a hydrophilic layer containing reduction nuclei, the hydrophilic layer being coated on an oleophilic surface of a backing, chemically reducing the salt to its metal at least at the hydrophilic/oleophilic interface, bleaching to remove the metal image and then removing the hydrophilic layer in the areas of formation of the metal image. The oleophilic backing is generally a paper support coated with an oleophilic layer. Selective permeation is achieved by using an imagewise exposed silver halide emulsion which is either coated on, or contacted with the hydrophilic layer reduction being achieved by the silver salt diffusion transfer process. In the examples, a paper support coated with a polyethylene or polypropylene layer or a polyester support is coated with an oleophilic layer of a vinyl chloride/vinyl acetate copolymer contaning titanium dioxide and overcoated with a hydrophilic silica layer containing colloidal silver. The silica layer either contains a humectant such as glycerine or is overcoated with a further silica layer not containing colloida silver so that the silver salt is precipitated at the oleophilic/hydrophilic interface. A silver halide emulsion may be coated on top of the silica layer and the material imagewise exposed and developed to produce a positive silver image at the interface by the diffusion transfer process or an exposed silver halide emulsion may be placed on top of the silica layer to produce a positive silver image at the interface development. The emulsion layer is removed where necessary and the positive silver image bleached out. Silica is now removed by rubbing and washing from the areas which contained the positive image to leave a lithographic plate; the bond between silica and the oleophilic layer being weakened by the formation of the silver image.
