Title: Improvements in or relating to electric alarm arrangements
Inventor: FAVELL BRIAN JEFFREY
IPC: G08B23/00
Filed: 1955-12-23
Abstract: 852,633. Protective arrangements; electromagnetic relays. REYROLLE & CO. Ltd., A. Dec. 18, 1956 [Dec. 23, 1955], No. 36962/55. Class 38 (5). [Also in Group XXXIX] In an electric alarm arrangement for use at a control station of an electric installation, the operating coil K of a relay in response to an initiating signal (e.g. a fault) is energized to move its contacts to the operative position (Fig. 2) to cause an alarm device H to give a warning indication (e.g. a flashing light), and in response to an acceptance control operation is de-energized to allow some of its contacts to revert to the normal position whilst the remaining contacts J<SP>2</SP>, J<SP>7</SP> remain latched in the operative position (Fig. 3) whereby the alarm device H is caused to give an action indication (e.g. a steady light), the latch K<SP>1</SP> being released in response to a reset operation to allow the remaining contacts to revert to the normal position (Figs. 1 and 4) and reset the alarm device to normal. In the arrangement of Fig. 4 the closure of initiating contacts G causes the operating coil K and an alarm bell B to be energized from bus-bars A<SP>1</SP>, A<SP>2</SP> over the contacts J<SP>2</SP>, J<SP>3</SP>. This causes the position of the contacts to be changed to the position of Fig. 2 so that a holding circuit for the coil K is completed from a bus-bar C<SP>1</SP> over the contacts J<SP>1</SP>, J<SP>2</SP>, J<SP>3</SP>, and a .lamp H is connected over contacts J<SP>9</SP>. J<SP>10</SP> to a bus-bar E<SP>1</SP> energized intermittently by means of an interrupter device E. The contacts J<SP>2</SP>, J<SP>7</SP> are latched so that when a " accept alarm" control switch C is opened and the coil K and bell B are de-energized, the relay contacts assume the position of Fig. 3. In this position the contact J<SP>3</SP> is isolated so that the coil K and the bell B cannot be re-energized and the lamp H is disconnected at contact J<SP>9</SP>, J<SP>10</SP> from the bus-bar E<SP>1</SP> but is connected over contacts J<SP>8</SP>, J<SP>7</SP> to the bus-bar A<SP>1</SP> so that the lamp H gives a steady light. When the latch is released, the contacts revert to the position of Figs. 1 and 4 and the lamp H is extinguished, it being disconnected from the bus-bar A<SP>1</SP> and connected to a test bus-bar D<SP>1</SP> over contacts J<SP>7</SP>, J<SP>8</SP>. The latch may be mechanical or magnetic and may be released manually. Alternatively a latch coil may apply or release the latch electromagnetically in which case the arrangement may be such that the latch is released automatically on the opening of the initiating contacts G, i.e. on removal of the fault. Each section of the installation would be provided with a relay and alarm device H, the bus-bars and bell being common to all the sections so that a blocking rectifier L is associated with each relay coil to prevent interaction between the relays.

Title: Method and apparatus for determining drift depth of impurities in semiconductors
IPC: H01L21/22
Filed: 1964-09-14
Abstract: 1,035,858. Semi-conductor devices. UNITED STATES ATOMIC ENERGY COMMISSION. Sept. 14, 1964 [Jan. 14, 1964], No. 37431/64. Heading H1K. In an impurity drifting process a P-N semiconductor body is heated while subjected to a reverse bias so that a compensated region is formed by impurity atoms drifted from one region into the other, and during the process measurement is made of the extent of impurity drift by means of a resistance measuring instrument connected across two electrodes placed on the surface of the region into which the impurity atoms are being drifted. The invention is particularly applicable to the manufacture of detectors for changed-particle radiation. In the embodiment shown a P-type silicon body having a tillium-doped region 12 and provided by washed vapour deposition with concentric ring and disc electrodes 16, 17 is placed on an annular heater 24 and subjected to a reverse bias to provide a compensated region 32. The central air space in the heater serves only to electrically isolate electrode 17, and may be filled with insulating material to give a more even distribution of heat. As the boundary of the compensated region nears the end face of the body the resistance measured by instrument 29 increases and provides an arcuate indication of the remaining thickness of the P-type region. The instrument may, as shown, be made to control the heater so that the process is automatically stopped when a desired minimum size of the P-type region has been reached, or alternatively the instrument may have a meter directly calibrated with the thickness of the P-type region so that manual control may be exercised. In both cases, to avoid interference caused by the drifting potential, the resistance measuring instrument preferably works on A.C or pulse techniques so that a D.C. isolating capacitor may be connected in one of its leads. The semi-conductor device may be completed by etching off contacts 16, 17 and providing the device with a new contact or the ring and disc may be plated over to fill the intervening gap and thus provide a continuous contact. The Specification states that the process may also be applied to germanium bodies, although less usefully.
