Abstract: 1,224,193. I.C. engines; mounting reciprocating pumps. BARKAS-WERKE VEB. Oct . 10, 1968, No. 48071/68. Headings F1A and F1B. A fuel injection pump 1 is mounted on the casing 5 of an internal combustion engine by seating the curved base 2 of the pump in a corresponding socket 3 in a bracket 4 and tightening bolts 8 screwed into holes in the bracket 4 so that the heads 9 of the bolts bear on productions 7 on the pump 1 to urge a further projection 11 on the opposite side of the pump upwards into engagement with an abutment 12 on the engine casing 5. The centre of curvature of the base 2 and socket 3 coincides with the centre 6 of the pump cam shaft mounting so that angular adjustment of the pump 1 in its socket 3 does not alter the position of the cam shaft. The socket 3 may be prism shaped instead of smoothly curved. Instead of being integral with the engine casing 5, the bracket 4 and abutment 12 may be integral with each other and bolted to the casing 5. The projection 11 may be bolted to the pump casing. In a modification, Fig. 2 (not shown), an adjusting screw (13) may be disposed between the facing surfaces of projection 11 and abutment 12, the screw being screwed into one or other of the surfaces and abutting the other surface. A locknut (14) is provided. In a further modification, Fig. 3 (not shown), the abutment on the engine casing side of the pump 1 is formed by a cylindrical pin (15) rotatably supported in a bore (16) in the engine casing 5 extending normal to the plane 18. The pin (15) has a head with one or more bearing surfaces (17) which abut the projection 11 on the pump casing. The pin (15) may alternatively be mounted in a bore in the pump casing to abut the engine casing 5.

Title: Binary signal sensing circuit
IPC: G11C7/00
Filed: 1969-10-07
Abstract: 1281029 Pulse shaping circuits INTERNATIONAL BUSINESS MACHINES CORP 7 Oct 1969 [10 Jan 1969] 49208/69 Heading H3T [Also in Division G4] A circuit arrangement for sensing input signals representing binary ones and zeros, switches bi-stable circuit means in sequence in response to exceeding of a threshold on two output lines of a difference amplifier, the sequence of switching being determined as an indication of a 1 or 0 input signal. A 1 or 0 non-destructively read from a memory device at 10 passes through a difference amplifier 11, an amplifier 14 and a transformer 15 to provide a positive peak followed by a negative peak at 26 or 27 (for 1 or 0 respectively) and the inverse of this at 27 or 26 respectively, 26 and 27 being inputs to a dual threshold circuit 28 each output 29, 30 of which is low when the corresponding input 26, 27 exceeds a positive threshold. Thus latches 31, 32 are set in turn to raise 38 and drop 39 in that order for 1 and the reverse order for 0, whereby a NAND 40 sets a latch 42 for 1 but not for 0. The latches 31, 32, 42 are reset after each bit via 33. Further circuitry may produce an error indication if one of the latches 31, 32 is set and the other is not within a predetermined interval thereafter, or if the two latches are set too close together. Details of dual threshold circuit 28 (Fig. 2).-A potential divider R7, R6 provides a positive threshold voltage from emitter follower transistor Q3 to the two halves of the rest of the circuit which produce respective outputs 29, 30 from the two inputs 26, 27. Taking the left half as typical, with a low input at 26, transistor Q4 and diode D3 conduct, transistor Q6 is cut off and transistor Q5 is almost cut off. A large enough positive input at 26, turns Q5 on and Q4 off, Q6 saturating to produce an output at 29.

Title: Production of crystalline bodies of complex geometries
IPC: C30B15/34
Filed: 1972-10-30
Abstract: 1382529 Crystal pulling TYCO LABORATORIES INC 30 Oct 1972 [8 Nov 1971] 49861/72 Heading BIS A "substantially monocrystalline" elongated body twisted along a selected axis is made by pulling a seed from a thin liquid film of material on a horizontal surface which terminates in sharp edges and has an edge configuration conforming to the desired cross-sectional configuration desired and simultaneously rotating the crystalline body about a selected axis whilst supplying material to the surface to maintain the film. The temperature of the film is controlled so that it is hottest near the surface. By "substantially monocrystalline" is meant a crystalline body comprised of a single crystal or two or more crystals growing together longitudinally but separated by a grain boundary of less than about 4. The material may be alumina ruby, spinel, beryllia, barium titanate, ythrium aluminium garnet, lithium niobate, lithium fluoride or calcium fluoride. The body may be a round rod with a spiral hole extending lengthwise, a hollow tube with a twist, a helical rod or tube, or a plate of dual axis curvature. Using the apparatus of figures 1 and 3, a monocrystalline tube of rectangular cross-section and having an axial twist is made by mounting a seed crystal 24, in chuck 22 with pulling rod 20 axially aligned with rod 38 of the die assembly shown in Figure 3. The crucible 12 is then filled with an inert gas and the R.F. coil 6 energized to melt the charge. The capillaries 46, fill with melt from melt 27 and the heating is adjusted so that the upper surface 44 of the die is about 10-40C higher than the melting point of the seed after which the seed crystal is lowered into contact with surface 44 and held there until connected with the melt in and from the capillaries by a film 48 (Figure 4) of the order of 0.1 mm. thickness. When the film is conected the pulling mechanism 18 is actuated to pull seed 24 upwards from the surface 44 without any rotation until growth is occurring from all points of the film, then the pulling mechanism is rotated. Growth is generally continued until the supply of melt is exhausted. Complex shapes can be produced by combining rotation of the seed crystal with a pulling movement of the type illustrated in Figures 11-13 (not shown), or by reverse rotation of the seed crystal.

Title: Method of and apparatus for winding a continuous web of material
IPC: B29C53/32
Filed: 1968-10-25
Abstract: 1,244,992. Winding webs. C. A. HARNDEN Ltd. 25 Oct., 1968 [9 Nov., 1967], No. 50869/68. Heading B8R. In winding a continuous web of material, e.g. of plastics film, crepe paper or the like, to form wound packages, a predetermined length of material is wound on a winding element; the element is then removed from the package which is thereby allowed to move away from the element; the web is held fast at a point between the element and the package; the element is re-engaged with the web and a new winding operation commenced; and the web is then severed at a point between the element and the holding point. As shown, a web 1 passes over a guide roller 2, associated with a brake 37, 38, to a winding element 3 which engages the web portion 4 and rotates to form a wound package 50. A revolution counter 48 associated with the roller 2 produces a signal when a predetermined length of material has been wound, and on receipt of this signal a control device 49 is programmed to initiate the following sequence of events: the winding element 3 is extracted from the wound package 50, which is thus allowed to fall on to a pivoted tray 40 (Fig. 2, not shown), and at the same time the brake 37, 38 is operated; a switch 40, actuated by the tray, then causes a holding device 6, 7, 8 to operate so that the web is held fast between fixed member 6 and movable member 8, the package 50 being moved by a push rod 8<SP>1</SP> to an outlet 41, leading to a conveyer or collecting container, where it is held in position by the web portion 51; the element 3 is then brought into engagement with the new web portion 4 and a new winding operation is commenced; when a few layers have been wound on the new package a cutting device 42, 43 is actuated to sever the web; the holding device, the cutting device and the brake are then released and the cycle repeats when the new winding operation is concluded. If the web is provided with lateral perforations, the slight tension arising between the element 3 and the holding device 6, 7, 8 during commencement of the new winding operation may be sufficient to sever the web along such a perforation, and in this instance the cutting device 42, 43 may be dispensed with. The winding element 3 (Figs. 4 to 6, not shown) may comprise two coaxial grippers each having two fingers to receive the web edge, the grippers being movable axially so that they can be engaged with and disengaged from opposite edges of the web, and also being rotatable to perform the winding operation. If it is desired to wind the package on a cardboard tube or the like, the winding element is appropriately adapted, e.g. by the provision of conical pins which are introduced into the ends of the tube for the winding operation.
