Abstract: 1349030 Spray carburettors DAIMLER-BENZ A G 12 Aug 1971 [14 Aug 1970] 37951/71 Heading F1B A carburettor having automatic enrichment for cold starting comprises a metering piston 6, Fig. 1, biased by a control lever 2 to a cold start spring- opposed limit position in which all transverse bores 10 can pass fuel from a flat chamber to an engine inlet pipe, the vacuum in the inlet pipe causing a pull-down lever 15 to pivot the control lever over a part of its full travel by engagement of a hook-part 15a with a control lever arm 2b, the control lever being pivoted over its full travel by a bimetallic spring 1 so that the metering piston assumes a normal operating position in which some of bores 10 are masked, the hook part 15a being movable, in response to engine temperature, by an actuating device towards the control lever when the latter is pivoted out of its cold start position by the part of its full travel. The engine is started in the cold condition with the control lever 2 in the Fig. 1 position with all bores 10 open for fuel flow. When the engine runs the suction in chamber 17 lifts lever 15 to pivot control lever 2 against spring 8 to the Fig. 2 position (not shown) so that spring 7 lifts piston 6 to close some bores 10. The Fig.2 position (not shown) also corresponds to the starting position for a half warm engine in which a bimetallic spring 21, responsive to engine temperature, moves the hook part 15a until step 22 can engage the arm 2b so that the lever 15 can pivot lever 2 by the usual amount whenthe engine runs.  In another embodiment the bimetallic spring 21 is omitted and a spring detent 24, Fig. 3, moves hook part 15a. A stop 27b engages a cam 26 to prevent movement of the hook part 15a when the engine is cold and not running. Step 22, Fig. 3 may be a plurality of steps arranged in staircase fashion. In another embodiment the lever 15 and chamber 17 is moved in entirety as a function of engine temperature so that shoulder 14 is located beneath end 2c up to half warm-up. End 2c may engage a ramp for precise temperature compensation. Lever 15 may be positioned by a thermostatic element or a further control lever arm which may engage a sliding housing part containing the assembly of the lever 15 and membrane chamber 17.

Title: Improvements in or relating to web coating apparatus
IPC: B05C1/08
Filed: 1956-12-14
Abstract: 855,539. Coating webs. KODAK Ltd. Dec. 14, 1956 [Dec. 14, 1955], No. 38186/56. Class 140. In a web-coating apparatus of the kind cornprising a rotatably mounted applicator roller partly immersed in a coating solution contained in a hopper, to apply the solution to the web to be coated or to an intermediate roller which transfers the solution to the web, and an inlet and an outlet for the coating solution at opposite ends of the hopper, fixed partitions are disposed in the bottom of the hopper, in spaced relation along it and of helical form, so that they intercept that portion of the solution which is moved by, but in a direction counter to, the rotation of the roller and cause the solution to move from the inlet end to the outlet end of the hopper. As shown, the roller 15 rotates in the solution S, which enters the hopper by the pipe 21 and is drawn off through the pipe 22. A baffle 25 extends along the bottom of hopper, and up the sides almost to the surface of the solution, separating it into two streams, flowing with and against the rotation of the roller. Helical ribs 26 on the baffle deflect the outer stream towards the outlet end of the hopper. These ribs may be of any cross-section, e.g. triangular or circular, but are preferably rectangular, as shown, and approach closely to the bottom and sides of the hopper so that flow of solution beneath them is minimized. The baffle may be closed at its ends by vertical walls 27, with flanges 27<SP>1</SP> to rest on the end walls of the hopper and so support the baffle. In another embodiment (not shown) the ribs are attached to the bottom of the hopper, and the baffle can in this case be dispensed with. A conduit 40 may be supplied, connecting a point in the hopper at the emerging side of the roller on one side of its middle with a point in the hopper at the entry side of the roller on the other side of its middle, or two such connections may be made in opposite directions.

Filed: 1969-07-30
Abstract: 1276699 Transistor logic circuits RCA CORPORATION 30 July 1969 [6 Aug 1968] 38232/69 Heading H3T [Also in Division G4] A logic circuit receiving a plurality of input signals such as A, A, B and C provides at two output terminals 11, 13 related logic functions y 1 , y 2 , those input signals common to the two functions (i.e. B, C) being applied to respective transistors 22, 24 connected between the two output terminals, and at least one signal in one output being the complement of one in the other output (A, #A) these two signals being applied to respective transistors 10, 16 connected between respective output terminals and a common point 4; respective loads 15, 17 connect the output terminals to a bias source 2. The circuit of Fig. 2 performs NOR functions and is said to require less transistors than known circuits (e.g., Fig. 1, not shown). The transistors are F.E.T.'s. For example, the output y 1  is at V- ("1") unless either T10 conducts due to A being negative ("1") or T22, or T24 conduct due to B or C being "1", the transistor 16 being conductive if T10 is not since it receives the complement of the T10 input. The output y 2  is derived similarly but with #A substituted for A, and F.E.T.'s 22, 24 conducting in the other direction. A decoding tree (Fig. 3, not shown) using F.E.T.'s has a plurality of NOR circuits as in Fig. 2, each load for the output terminals (0- 7) being constituted by a transistor (222, 223 ... 229) which transistors form part of respective branches of a transfer tree (3). The transfer tree (3) has F.E.T.'s of opposite conductivity type to the NOR circuit and has three layers of branching the lowest receiving the C, C inputs; the next the B, B inputs; and the top layer the A, #A inputs. In operation only one of the outputs 0-7 is at any one time connected to the terminal 2 to give V - ("1") and simultaneously disconnected from the positive voltage (at 4) by the corresponding NOR gate. The output position giving a "1" is selected by the combination of A, #A, B, B, C, #C signals in the NOR gates (5) and the transfer tree (3), this combination being the binary equivalent of the decimal output given at 0-7. A complete binary-decimal decoder is described (Fig. 4, not shown) giving 0-9 outputs, and adds to the circuit of Fig. 3 (not shown) a F.E.T. (131) receiving a D input connected across the 0 and 1 output positions, and a further stage (9) having one NOR gate (108, 109, 128) with F.E.T.'s (230, 231) for loads; a further branch in the decoding tree is included using F.E.T.'s (190, 192) receiving D, D inputs and connected respectively to the circuit 3 of Fig. 3 (not shown) and to the further stage (9).

In Fig. 2 (not shown), the rollers 3c, 3d drive step-up gearing to wind a clockwork spring mechanism and, if supplemented, the energy thus stored can be used to drive the rollers 2a, 2b. In Fig. 3, the indicator 8 records through ink ribbon 12, which is driven by rollers 10a, 10b, themselves driven through gear-wheel 9 by rollers 3c, 3d. The ribbon 12 can also be tensioned in a similar way. In Fig. 4 the rollers 3d, 2f are coupled, some slip being allowed by mounting the roller 3c on a spring-loaded lever 6a. In Fig. 5, the rollers 3c, 3d are coupled by a free-wheel gear arrangement 5a, 5b, 5c to the driving rollers 2a, 2b, the rollers 3c, 3d being driven only by the carrier 1. The braking mechanism may be coupled to an electric generator which may supply current to, e.g. pilot lamps.

Title: Improvements in or relating to the production of alloys of beryllium with heavy basemetals
IPC: C22C28/00
Filed: 1930-12-23
Abstract: Alloys of beryllium with heavy base metals such as iron, copper, or nickel are prepared by liberating beryllium from an easily fusible slag containing at least one alkaline earth-metal oxide and beryllium oxide with or without the addition of one or more alkali metal oxides by means of a reducing agent such as carbon silicon, or aluminium, or one or more carbides in the presence of one or more fused heavy metals.  Compounds of beryllium and of the alkali and alkaline earth metals which at the reaction temperature are converted into oxides may be employed, for example, carbonates.  The process may be operated continuously by the addition from time to time of further beryllium oxide and reducing agent.  Any reducing agent or other impurities remaining in the alloy may be removed by reaction with a further quantity of the slag.  In one of the examples included, calcium fluoride is used as a flux.
