Patent GB-1168357-A (GB)
Title: A process for the production of Semiconductor Devices
IPC: H01L21/52
Filed: 1967-08-20
Abstract: 1,168,357. Soldering. SIEMENS A.G. 25 Aug., 1967 [26 Aug., 1966; 22 Sept., 1966], No. 39313/67. Heading B3R. [Also in Division H1] A plurality of PN junction semi-conductor devices are manufactured by mounting separate device bodies on a common conductive support, attaching an individual contact member to each body, bonding each body to the common support and to its individual contact by soldering, etching the bodies and coating their exposed sides with lacquer, and finally separating each portion of the support carrying one device from the other such portions. Fig. 3 shows part of the common support 1 which consists of an iron sheet coated on both sides with first nickel and then lead, the latter serving as a solder. At each location where the support is required to mount a semi-conductor body, a portion of appropriate dimensions has been partly punched through. Each such portion constitutes a boss 2 and a jig 52 of complementary form to the embossed support is fitted over it so that each boss 2 lies in an aperture 53 in the jig. Within each aperture 53 is deposited first a semi-conductor body 6 and then a contact member 7 coated on both sides with lead. The whole is then heated to melt the lead and thus solder each semi-conductor body between a boss 2 on the common support and a contact member 7. The body 52 is then removed, the devices etched and lacquer coated, and the bosses punched right out of the support to separate the individual devices. The lacquer 8, Fig. 4 (not shown), surrounds the semi-conductor body and the contact member but does not cover the free surface of the latter. The lead coating on this free surface may be removed after the lacquering step, but before separation of the individual devices, by immersion of the assembly in a tin bath. After separation of the devices, the contact members may be soldered to suitable terminals by a method which forms the subject of Specification 1,168,358. In an alternative process (not illustrated) the embossed sheet is replaced by a sheet from which portions are completely stamped out leaving device-supporting portions connected only by easily ruptured narrow webs. The stamped-out portions may be used as the separate contact members.

Abstract: 1370033 Sterilization apparatus ATAD 24 Aug 1972 39448/72 Addition to 1217959 Heading A2D A sterilizing apparatus comprises a disc driven in rotation around its axis inside a casing, the gap between each moving face of the disc and the opposing fixed face of the casing being of the order of 0.2-0.3 mm., the product to be treated being introduced into the space between the disc and the casing adjacent the axis of rotation of the disc and escaping adjacent its periphery, the disc being made of steel having a high limit of elasticity and being clamped by a clamping ring gripping its periphery. The ring may be connected to the disc by welding, keying. or screwing. The casing may be atached to its base in the plane of symmetry of the casing lying at right angles to the axis of rotation of the disc, so that the casing can slide freely in the axial direction in relation to the disc axis. There may also be provided temperature sensing members disposed on either side of the disc in the flow gaps for the product to be treated, these members delivering signals to a relay controlling the rotation of a motor enabling the disc to make an axial movement in relation to the casing during operation. A suitable apparatus is shown in Fig. 9, wherein a disc 210, which is peripherally clamped by ring 211, is rotatably mounted on an axis 213 inside a casing 212. Thermocouples 214a, 214b are connected to relay 215 which is itself connected to an electric motor 216. If the temperature difference between the gaps on either side of the disc exceeds certain value, a current flows from the relay to the electric motor. This motor drives a low pitch screw 218 which co-operates with a nut 217, thus altering the position of the disc in the casing so as to lessen the temperature difference. The apparatus is particularly suitable for the sterilization of milk.
