IPC: H01K13/00
Filed: 1968-09-17
Abstract: 1,224,389. Assembly components into printed circuit boards. VISION ENG. Ltd. 24 Oct.. 1969 [17 Sept., 1968], No. 44060/68. Heading B3A. A machine for facilitating the assembly of electronic components into printed circuit boards includes an indicator for the positioning of the components on an actual circuit board comprising a replica board having holes equivalent to those in a board to be assembled. Replica circuit boards are placed on tables 16a, 17a, the boards being through drilled in positions corresponding to the component positions on the actual board, which is fixed in holders 18, 19. The operator moves a handle 15 to bring a stylus 9a above one of the holes in the uppermost replica board, thereby bringing a contactor tip 35 into contact with a stud 30 exposed through a hole in the lower replica board to illuminate a lamp 34 on a component storage bin. Simultaneously, a spotlight projection head 10a is shifted to illuminate the position on the actual circuit board where the component from the indicated bin is to be fitted. Having fitted the component the operator presses a switch 37 or 37a and a ball bearing is ejected into the hole beneath the stylus 9a, thus obscuring illumination from a fluorescent lamp 29. When all the holes have been obscured, a handle 38 is raised to lift the replica board to allow the balls to fall through the holes therein and roll down into a collection hopper 39.

Abstract: 1,059,058. Taper micrometers. G.L. GERSHAM. Oct. 21, 1965, No. 44607/65. Headings G1M and G1X. An internal taper micrometer comprises a pair of elongated anvils 10, 12 each anvil having a flat surface 32, 36 and a partially conical surface 20, 18 so as to present a single conical member when the flat surfaces are in contact. The micrometer is characterized by the provision of a pin 26 on one anvil, a member 30 fixed to the other anvil receiving the pin and pivotally mounting the anvils for motion relative to each other. A direct reading increment measuring device 42 is mounted in one end of the anvil 12 and comprises a finger 40 having a flat face at its free end which engages a cylindrical roll 38 on a bar 34 mounted on the anvil 10. Operation of the micrometer screw moves the cylindrical roll 38 and hence pivots the two anvils relative to each other.

Title: Improvements in or relating to pumps and methods of pumping
Inventor: FRENCH MICHAEL
IPC: F04F5/54
Filed: 1967-09-30
Abstract: 1,209,606. Gas pumps; jet pumps. GAS COUNCIL. Sept. 27, 1968 [Sept. 30, 1967], No.44618/67. Headings F1E and F1N. Hot gas in a main conduit 1 is pumped by reciprocating a column of gas in a branch connection 3. In the embodiment shown, the lower upstream and upper downstream parts of the main conduit 1 are separated by a pumping chamber 28 connected to the branch 3 and having inlet and outlet valves 5, 4. Thus, when gas in the branch 3 flows away from the conduit 1, hot gas enters the chamber 28 through the valve 5 and when the flow is reversed the gas is forced through the outlet valve 4. In a second embodiment the valves are dispensed with and the branch 3 terminates in a jet co-axial with the conduit. By arranging for the flow out of the jet to be at a higher speed and for a shorter duration than the return flow into the jet, flow is induced in the conduit 1. To reciprocate the gas column the branch 3 is alternately connected to the inlet and outlet conduits 45, 44 of a blower or fan42, possibly including reservoirs 40, 41. A continuously rotating valve 43 or two alternately operating on/off valves control the alternate inter-connection. The branch conduit may be externally cooled.

Title: Method for growing a mixed crystal with controlled composition
IPC: H01L21/208
Filed: 1970-09-21
Abstract: 1,270,065. Mixed crystals. INTERNATIONAL BUSINESS MACHINES CORP. 21 Sept., 1970 [23 Sept., 1969], No. 44809/70. Heading BIG. Mixed crystals are grown from a melt containing one component on to a seed of the other, the melt being supplied with the second component by contacting it with the solid form of this component at another point. The melt has the composition from which a solid of the desired mole fractions of its components will be precipitated on freezing, and is maintained at this composition by equilibriating it at constant temperature with the second component source. The temperature at the point of contact between the liquid and the seed is controlled to permit freezing, and hence crystal growth to occur. By varying the equilibrium temperature, it is possible to prepare mixed crystals whose composition varies either gradually or stepwise in the growth direction. In the embodiment described a mixed crystal of GaP and InP is prepared. The lower melting compound, InP, is sandwiched between two layers of Gap, the InP melted and equilibrated with the GaP, the lower interface cooled to permit crystal growth and the ensemble slowly lowered through a cooled zone so that growth occurs upwards. Additional phosphorus vapour is supplied to keep the vapour pressure equal to or above the dissociation pressure of the phosphorus. The process may also be used for ternary &c systems.
