A stationary deflecting arm 32 has its edge 33 covering the holes 21 as they pass it but leaving the holes 22 at least partially uncovered. As the wheel rotates in the direction f, of the several seeds a, b, c picked up by a hole 21 by means of suction applied via pipe 26 and space 27a, only the leading seed a is transferred to the corresponding hole 22 as the seeds a, b, c are deflected radially inwardly by the arm 32 towards the hole 22 to which suction is applied beyond the arm 32 via pipe 26 and space 27b. The seed a is carried beyond the region 27b on a fin 24 into a descent passageway 36 and falls down over the edge 37a out of the opening 37. In Fig. 4 (not shown) the holes 21, 22 are formed in a ring which is releasably attached to the hub of the wheel 8 so that different sized holes may be provided for different seeds. In Fig. 5 (not shown) the wheel 8 consists of two discs disposed over one another and separated by the fins 24. In Fig. 6 (not shown) the descent passageway is narrower than shown in Figs. 1-3 and the fins 24 do not extend completely between adjacent sets of holes 21, 22.

In Fig. 11 (not shown) three concentric circles of holes are provided, seeds being transferred from the outer to the middle holes and then to the inner holes. The second transfer may be necessary to ensure that only one seed is left in the inner hole if light seeds are being planted.

Abstract: 1284068 Crystal-pulling SIEMENS AG 23 Sept 1970 [24 Sept 1969] 45193/70 Heading B1S In a crystal-pulling process where a sealcrystal is used, the material from which the crystal is to be pulled is, prior to melting, heated to a temperature such that it becomes a good enough conductor of electricity for induction heating to occur. This is accomplished by heating the seed-crystal so that its free end at least is heated and presenting the heated crystal to the material when the conductivity has risen high enough as a result of this treatment, the material is melted by an induction coil and conventional crystal-pulling occurs. In the illustrated embodiment, crucible 2 is kept in a shielding gas and cooled by water passing along tubes and rings 6, 3a, 4a, 5, 4b, 3b and 7. Induction coil 8 is wound around the crucible 2. Seed crystal 11 is mounted in holder 10 and shaft 19. Induction coil 13 is mounted on movable shaft 12. Holder 10 is made of highly conductive steel and at the start of the operation is coupled electrically to the field of coil 13. This heats crystal 11 so that its conductivity rises to the point where it may be heated by coil 13. By moving the coil 13 relative to crystal 11, the tip of the crystal may be melted. The crystal is then moved down so that the melt touches the material 9 and heats it. Conventional crystal-pulling may then occur. The coil of the process to obtain a crystal of silicon, which does not couple satisfactorily until at a temperature above 600C is described.

A fluid-operated press comprises an expansible diaphragm means 22 lining the interior surface of a deformable work - engaging pad 94 which is adapted to be expanded and pressed against a workpiece 74 and has a relatively thick central body and peripheral flange bent inwardly to partially lap adjacent portions of the body and provide therewith a recess for receiving portions 124 of a mounting liner member 106, the marginal portion 132 of the flange being of thickness greater than the adjacent portion merging into the body for providing a wedging portion co-operative with the liner for restricting displacement of the flange from its assembled position. The liner member 106 is formed with the flanged portion 124 around which the diaphragm and workengaging pad 84 are disposed, the diaphragm being secured to the liner member by adhesive 130. The pad is disposed within a roof casting 86 to which the liner member is attached by a hollow stem 108 passing through the casting and a bush 112 in an outer casing 12, a nut 114 being threaded on the outer end of the stem. A tray 22 having rollers 23, 24 engaging guideways 42 is movable by a rack-and-pinion mechanism 46, 50 from a work-loading position outside the casing to an operative position within the casing to locate the workpiece 74 on a die 72 beneath the pad 94 so that when hydraulic pressure is supplied through the stem 108, the pad is deformed to press the workpiece against the die. Extrusion of the pad into the space 136 between the tray 22 and casting 86 is prevented by a sealing ring 138 which may be of extruded aluminium. When the tray is in its operative position, the rollers 23, 24 are disposed above portions 58, 64 of the guideways which move against springs 60, 68 to permit the load on the tray during the pressing operation to be taken by the casing 12. Two trays may be provided to permit loading of a workpiece on one tray whilst a workpiece is being formed on the other. Means for heating the workpiece may be provided in the tray 22.

Abstract: 1352440 Exposure meters ASAHI KOGAKU KOGYO K K 4 Oct 1971 [2 Oct 1970] 46125/71 Heading G2X In a device for detecting the intensity of an object to be photographed, signals dependent on both the incident highest and lowest partial density are received by a photo-conductor R of a transistorized control circuit Q 1 -Q 6  and an output signal giving an indication of the average illumination of the object is then passed to an indicator or to a shutter actuating circuit. Fig. 1 shows a detector comprising the series connected photoconductor R, log compression element D 0 , parallel capacitors and diodes D 1  D 2  each capacitor serving to store signals indicating low incident intensity C 1  and high incident intensity C 2  which subsequently trigger the control circuit Q 1 -Q 6  to develop a potential across variable resistance ro indicating the difference between the signals. A switch T is so arranged so that half this potential i.e. half the difference between the high and low intensity signals, is taken off through a b and is held on capacitor C o . When switch T is closed on a' b' the potential on C 0  is added to the potential difference developed in load resistance re by transistor Q 3  from the low intensity signal, giving an average intensity value which is passed to indicator M. If b, b' are connected to the electrodes of Q 5  an average intensity value is also given from the difference figure on C o  subtracted from the highest intensity value. In a modification Fig. 2 (not shown) a series of photo-conductors (R 1  R 3 ...) receive high incidence intensity signals and photo-conductors (R 2  R 4 ...) receive low intensity signals, which are passed through log diodes and diodes (D' 1  D' 3  and D' 2  D' 4 ) to either side of the transistor control circuit. A capacitor (c) is then charged with the difference between these signals, and the resulting signal may be added to subtracted with either of the individual signals by the switching operation T us described before.
