Abstract: 1,058,727. Counters. ELMEG ELEKTRO MECHANIK G.m.b.H. May 8, 1964 [May 9. 1963], No. 19320/64. Heading G4D. A control mechanism repeatedly resets a counter after the reception of a predetermined number of impulses and cuts off the supply of impulses during the resetting operation. A disc 1 attached to a numeral wheel maintains composite lever 3, 4 in the position shown during the reception of impulses which advance the counter wheel electromagnetically. When roller 3<SP>1</SP> drops into notch 2 at the predetermined count, nose 4<SP>1</SP> releases leaf spring 5 so that switch 6 closes to energize magnet 7. Bellcrank 10 is thereby rocked clockwise to open switch 12 to cut off the supply of counter impulses. Magnet 7 also initiates resetting of the counter after which it restores, bellerank 10 allowing switch 12 to close again and also restoring leaf spring 5, switch 6 and composite lever 3, 4 to original positions. A number of denominations may be used, each with a lever 3, simultaneous operation of the levers 3 being necessary for operation of the device.

Title: Improvements in or relating to data storage devices
Inventor: JAMES JOHN BERNARD
IPC: G11C11/06
Filed: 1959-06-08
Abstract: 936,121. Circuits employing bi-stable magnetic elements. INTERNATIONAL COMPUTERS & TABULATORS Ltd. May 24, 1960 [June 8, 1959], No. 19490/59. Class 40 (9). [Also in Group XIX] Two solid state bi-stable elements, such as magnetic cores 28, 30 (Fig. 3), or ferroelectric elements, are reciprocally coupled and switching means act on one of the elements so as to change its state either at a relatively fast, or a relatively slow, rate, the coupling being such that only when the one element is fast switched is the state of the other element changed. In the arrangement shown in Fig. 3, the magnitude of the current in line 31 varies and with the impedance of the coupling 33 determines the rate of switching of core 30 whereas in Fig. 5 the current in line 63 is always sufficient to switch core 62 quickly but a load winding 64, resistive or inductive, is energized when slow switching is required. If ferroelectric elements are used independent switching is obtained by switching an element at slow speed so that only a small output is obtained which operates on the exponential part of the characteristic of the other element. The device is embodied in a matrix in apparatus for printing data stored on punched cards (see Group XIX). Specification 806,487 is referred to.

Title: Combine harvester
IPC: A01F7/06
Filed: 1969-04-17
Abstract: 1,209,280. Combine harvester. WHITE MOTOR CORP. 17 April, 1969 [17 April, 1968], No. 19582/69. Heading A1F. [Also in Divisions B2, B8 and F1] A combine harvester 10 has a header 20 to feed the crop into a threshing cylinder 50, which is mounted longitudinally of the harvester and advances the crop material along its axis while simultaneously threshing it, a separating assembly 26, a grain cleansing mechanism, and trash discharge means. The harvester 10, Figs. 1-2, is driven by a single power unit 14. The header 20 may be pivoted at 39 to adjust its cutting height by hydraulic means; it includes a table 40 having a cutter bar 41 disposed beneath reel 42, a screw conveyer 43 carrying the cut crop inwards to the centre of the header. A beater 44 advances the crop to a screw conveyer 45 which feeds it into a blower 47 and thereby into a housing 48 of threshing cylinder 50 mounted at the forward end of shaft 56. Blades 61 are mounted on the cylinder 50 to advance the material towards separator 26, Fig. 6. The material is carried through the separator 26 by blades 81 and is distributed thinly over separator tube 82 by flexible fingers 83 mounted on shaft 80. The straw passes to the end of the separator 26 where it is ejected by paddles 88 through opening 87. The grain and fine chaff pass through a grate 65, and separator tube 82, and fall on to screw conveyers 28 in the bottom of the machine. Screws 91 and 90, Fig. 2, convey the material to slingers 97 and 98, Fig. 14, at the rear of the machine. The material is delivered through shoot 104 to the bottom of the cleaner 30 and is lifted by screw 100. The lighter chaff and grain pass through a screen 101 while the coarse material is retained within it. The lighter chaff is carried upwards in the cleaner housing 107 by operation of suction fan 109 while the cleaned grain drops to pan 106 at the base of housing 107. From pan 106 the grain is swept by paddles 117 to a shoot (119), Fig 10 (not shown). The grain passes to a slinger chamber (125), to be thrown by slinger blades (128) up a shoot 131, Fig. 1, into storage tank 34 where it is evenly distributed by fan 132. The chaff sucked up in the cleaner housing 107, Fig. 14, by the fan 109 and the coarse chaff moved up by screw 100 are discharged through a shoot 115. Shaft 122 carrying slinger 128 also carries slinger (129), Fig. 12 (not shown), for discharging grain stored in the tank 34 through a shoot 36. The slinger (129) rotates in a housing 120, thus operating as a centrifugal pump. When the pump stops, grain is prevented from falling into the pump and clogging it by a port 201, Fig. 14, which returns the grain to the storage tank. Screw conveyer 137, Fig. 10 (not shown), transfers grain from the bottom of storage tank (34) through an opening (134) for discharge from the machine on raising of a gate (141), Fig. 11 (not shown).

Abstract: 871,373. Compression moulding. HORN, D. June 21, 1957 [June 22, 1956], No. 19600/57. Class 87(2). Pressure members adapted to compress a mass in all three dimensions are arranged so that movement of one pressure member in its direction of pressing causes simultaneous movement of another member in its direction of pressing. Pressure may be applied firstly in two dimensions simultaneously and subsequently in the third dimension. Alternatively, precompression may be effected in one dimension and final compression in the second and third dimensions. As a further alternative, pressure may be applied in all three dimensions simultaneously. Figs. 3 and 4 show a mould comprising four wedge-shaped members 15 movable horizontally and vertically on sloping faces of a frame 16. On descent of a pressure member 18 the wedges 15 are forced downwardly and inwardly to the dotted line position in Fig. 3 against the action of springs 22 with an interposed plate 20. A final pressing is effected by a high pressure short stroke member 17. The pressure members may have grooved, ribbed or otherwise embossed faces, the embossing being on a separate laterally movable cover plate in the case of laterally movable platens. In Figs. 7, 8 (not shown) the upper pressure member is resiliently mounted and is centrally apertured to receive an additional vertically movable pressure member, pressure being applied on all sides simultaneously.

Title: Valve seat grinding tool
Inventor: EMGE HERBERT MICHAEL
IPC: B24B15/00
Filed: 1952-08-05
Abstract: 708,611. Grinding valve seats. BLACK & DECKER MANUFACTURING CO. Aug. 5, 1952, No. 19670/52. Class 60 A tool for grinding valve seats comprises a pilot stem P mounted in the valve guide Q of an engine motor block and supporting and guiding a grinding stone sleeve S to which is secured a valve seat grinding stone R. The. sleeve S comprises an outer sleeve 10 having a neck 11 on which the stone is mounted, the neck being threaded to engage a threaded hub portion in the stone; alternatively the stone may be retained on the neck by a nut and washer. The outer sleeve 10 is rotatably mounted upon an inner sleeve 13 by ball bearings 14, 15, 16. A plug 28 screwed into the upper end of the outer sleeve 10 has an hexagonal pocket 31 serving for the application of a portable motor driven wrench or other high speed rotating means. The inner sleeve 13 is a close sliding fit on the pilot stem P; rotation of the inner sleeve 13 on the stem is prevented by steel-balls 33 carried in pockets 34 of the inner sleeve 13 and projecting into longitudinal grooves 35 of the stem. A spring 41 bears at its lower end against a plunger 40 in the upper end of the inner sleeve 13, the plunger having a flange 43 co-operating with a shoulder 42 on the sleeve; the upper end of the spring 41 bears against a disc 44 retained in the sleeve 13 by a snap ring 45. Thus, as long as no downward pressure is applied to the stone sleeve, the plunger 40 in contact with the upper end of the pilot stem holds the stone lifted out of contact with the valve seat; when a power wrench or other driving means is applied to the sleeve, the downward pressure thereof depresses the stone sleeve against the bias of the spring 41, the plunger 40 moving upwardly relatively to the sleeve 13, thus .allowing the stone to come into working contact with the seat to be ground. As soon as the grinding pressure is released or the driving tool is removed from the socket 31, the sleeve is immediately raised by the action of the spring to lift the stone out of contact with the surface so preventing marring of the finished valve seat, caused by the stone dragging thereon during rotation after driving pressure is removed. Specification 545,863 is referred to.
