Patent GB-1036621-A (GB)
Title: Improvements in or relating to bacterial vaccines
IPC: A61K39/02
Filed: 1963-02-20
Abstract: Somatic antigen vaccines are prepared by lysing the killed cells of at least one selected strain of pathogenic bacteria other than staphylococci by exposing them to the action of dornase.  It is preferred to inactivate the dornase but this must be done without destroying the antigenic properties of the vaccine e.g. by heating at 56 DEG C for 1 hour.  Vaccines derived from staphylococci may be obtained in this preferred way, especially vaccines for treating mastitis in cattle and derived from mixed strains of both staphylococci and streptococci.  A proteolytic enzyme such as trypsin may be added to the dornase and lysis may be expedited by the further addition of a wetting agent.  Examples relate to the preparation of vaccines effective against staphylococcal infections, typhoid, meningococcal infections, pertussis, streptococcal infections, BCG and mastitis.

Title: Improvements in or relating to the manufacture of transistors
IPC: H01L21/22

Abstract: 1,046,155. Transistors. SIEMENS & HALSKE A.G. Feb. 22, 1965 [Feb. 24, 1964], No. 7504/65. Heading H1K. A transistor is made by vapour diffusing into a body or zone of semi-conductor material of N(P) conductivity type on acceptor (donor) impurity through a masking layer pervious thereto, then forming an aperture through the masking and continuing the diffusion to form an N(P) zone, and finally vapour diffusing a donor (acceptor) impurity to which the masking is impervious through the aperture to form a P(N) zone within the diffused N(P) zone. An NPN germanium transistor is made in this way using a masking layer of silica or alumina on an N-type wafer, zinc, indium or gallium as the acceptor impurity and arsenic, antimony or phosphorus as donor. If a PNP transistor is required from a P-type collector wafer, lithium is diffused to form the base and boron to form the emitter. In a preferred method, immediately after formation of the aperture by etching in hydrochloric acid, the thickness of the diffused zone under the aperture is reduced by etching in hydrogen peroxide. After electrodes have been attached e.g. by thermocompression bonding the masking layer may be reinforced to protect the device. Silica masking may be formed by evaporation, or by precipitation from a reaction gas e.g. a mixture of silicon monoxide and oxygen, or of an alkoxysilane and inert gas. Reaction temperature may be reduced by using the ionizing effect of a glow discharge. Application of the method to manufacture of hook collector transistors and the use of silicon are also suggested.

Abstract: 634,792. Burglar alarms. WARE, J. L., and LANKTREE, P. A. D. March 19, 1947, No. 7631. [Class 118 (i)] An alarm unit for a burglar alarm of the current-normally-flowing type is adapted for A.C. mains supply by the provision of a transformer 1 and rectifier 6 whereby a low-tension D.C. supply is available for the relay 9 and external circuit 7. On switching on the mains supply by switch 14 the alarm bell 2 will sound until the relay is set by push-button switch 12 and this can only be done if all the contacts 8 (situated on the doors, windows, &c. to be protected) are closed. When thus operated, the relay closes contacts 10, maintaining its own winding in series with the external protection circuit 7, and contacts 4 are opened, holding the alarm circuit open. If the external circuit is now broken by any of contacts 8, the relay releases, closes the alarm circuit and opens its own circuit at contacts 10, thus preventing resetting and cancellation of the alarm by restoration of the external circuit. A switch 13 is provided to break the circuit 7 for test purposes. Additional contacts 50 may be provided on the relay together with switch 51 and socket 52 for connection of a mains voltage gong outside the building. The switch 17 may - be provided as a guard against tampering with the unit after switching off by switch 14 and is automatically closed if the lid of the box is opened, thus sounding the alarm. According to the Provisional Specification a second relay is provided and so connected that opening the lid of the box causes it to be de-energized, thereby closing the switch 17. Figs. 4 and 5 (not shown) illustrate means of protecting doors and windows respectively and Fig. 6 (not shown) indicates an arrangement whereby part of the protective circuit may be rendered inoperative without nullifying the remainder. In an alternative arrangement both leads to the relay 9 constitute the external circuit and switches 8 are adapted to be normally open and on closure short-circuit the leads, thereby deenergizing the relay and sounding the alarm as above.
