Title: Improvements in semiconductor devices and methods of making same
IPC: H01L21/00
Filed: 1957-09-25
Abstract: 836,851. Semi-conductor devices. GENERAL ELECTRIC CO. Sept. 25, 1957 [Sept. 26, 1956], No. 30078/57. Class 37. A method of making a semi-conductor device comprises the steps of alloying a donor or acceptor impurity to a surface of a P or N-type semi-conductor body to provide a regrown N or P-type region forming a PN junction with the body, adding to the impurity another donor or acceptor impurity having a higher solid solubility in the semi-conductor and alloying the combined donors or acceptors with the regrown region at a lower temperature to form a second regrown region of higher conductivity but of the same conductivity type as the first regrown region. In the embodiment (Fig. 3), two dots of indium 11, 16 on opposite faces of an N- type germanium wafer are gradually heated to 585 C. and slowly cooled to form recrystallized P-type zones 12, 17. Pellets of indium 13, 18 containing 2% aluminium are then applied to the indium pellets to give reconstituted dots containing from 0.1 to 10 parts of aluminium per 100 parts of indium. The dots are reheated to 550 C. and cooled to form recrystallized high-conductivity zones 14, 20 (Fig. 4), on top of the undissolved parts 12, 17 of the first zones. Electrodes 21, 22, 23 are then attached to the dots and wafer in conventional manner. Transistors made in this way exhibit a much slower falling off of current amplification factor with increasing collector current than indium fused junction transistors due to their increased emitter efficiency. At the same time they possess the uniform junctions and good mechanical properties associated with the use of indium. Specification 753,133 is referred to.

Title: Improvements in electric burglar alarms
IPC: G08B13/22
Filed: 1925-11-28
Abstract: 262,257. Eisler, H., and Eisler, G. W. Nov. 28, 1925. Burglar alarms.- In an alarm of the closed-circuit type, comprising a relay B in the normallyclosed circuit C for controlling the alarm circuit E, the armature tongue A of the relay is given such a travel that when it is in its lowermost position the normal excitation oi the magnet is insufficient to raise it, and separate means, such as the lever M, actuated by a separate electromagnet 0 are employed tc bring it to an intermediate position from which it can be raised to its uppermost position by the relay magnet. In the Figure, the tongue is shown raised to its intermediate position by the weighted lever M, no alarm sounding, but on the closing of a control lock H to set the device, the switch J is closed and the bell circuit is closed through the shunt S, the lever M, and the armature A, the bell continuing to ring until a switch L is closed with the closing of a final exit door. This switch completes the normally closed circuit to raise the armature A and release the lever M, and an alarm is then given on opening of any of the closed circuit contacts C<11>. Should the push P not be operated, an alarm is given through the circuit E, and should the lock H not be closed, the closing of the exit door completes a shunt circuit T through contacts V to give warning of the omission. To prevent an unauthorized person re-setting the lever M, the circuit of the push P is broken when the lock H is closed, the bolt leaving the switch arm J. A compression spring A<1> ensures that the armature falls when the magnets B are energized.

Abstract: 1,004,839. Combination locks. O. SELLIN. Aug. 7, 1962 [Aug. 8, 1961], No. 30171/62. Heading E2A. A combination lock with a code number setting knob adapted to unlock the lock by alternative rotation of the knob in opposite directions and by thus consecutively setting a rotatable graduated disc to predetermined numbers, comprises means for operatively coupling the setting knob with the graduated disc when the knob has been rotated in the prescribed direction the prescribed number of times corresponding to each number of the code. To unlock the connection lock knob c is turned anti-clockwise, as shown in Fig. 1, causing lug c to engage in slot d of entraining ring d so that on further rotation of the knob c lugs d 2 , e 1 , f 1 , g 1 , of rings d, e, f, g consecutively abut teeth e 2  f 1  g 2  h 2  respectively. Finally as the lug g engages the tooth h 2 , the tooth h 1  raises a pawl i and forces a tooth i 1  into engagement with the tooth h 2  and the knob c is set against the first appropriate number of the code. Knob c is then turned in the opposite direction until the tooth g 2  is engaged with the pawl k, and it can then be moved to a second setting position. These rotations in opposite directions are continued, picking up one less ring at each rotation in the same direction, until the disc b is entrained by the knob c when the required number of the disc b is then turned into register with the index mark, and the lock may be opened. For resetting to the numbers of a different code the appropriate numbers are selected in sequence, the setting process being stopped at the last number. A re-setting key is then introduced into the lock and moved through 90 degrees to adjust the lock to the new code. The new digits are set by reverse rotations of the setting knob and locking them with the re-setting key.

Title: Flexure-sensitive electromechanical transducer device
IPC: H04R17/00
Filed: 1949-11-28
Abstract: 672,228. Piezo-electric crystals. BRUSH DEVELOPMENT CO. Nov. 28, 1949 [Dec. 28, 1948], No. 30442/49. Class 40 (viii). A piezo-electric transducer element comprises a body free from structural discontinuities, one portion of which is of a dielectric material polarized to have a certain electro-mechanical transducing characteristic, and another portion of which has a different composition so as to have a different transducing characteristic, so that mechanical reaction between the two portions causes the element to operate by bending. In Fig. 5, a dielectric bar 21, preferably of a polycrystalline barium titanate ceramic, is fixed on a base 27 so that endwise movement of a shaft 29 to bend the bar causes simultaneous compression and extension of opposite sideportions of the bar underlying the respective electrodes 22, 23. As these portions have different transducing characteristics, a voltage appears across terminals 25, 26. One method of making element 21 comprises firing together a thin sheet of raw barium titanate and a thin sheet of raw barium-strontium titanate. The interface is eliminated by incipient sintering and vitrifying. Alternatively the element 21 may be formed by dipping a backing structure successively into aqueous dispersions of barium titanate and barium-strontium titanate, to form contiguous layers as described in Specification 672,226. Another method comprises covering one side of a barium titanate sheet with powdered strontium titanate and a flux. After ceramic firing, one side portion of the sheet will be converted into barium-strontium titanate. A similar result may be obtained by using stannic oxide. In the above elements, both portions are of dielectric materials, but only the barium titanate portion is capable of retaining any appreciable remanant polarization. Alternatively, one portion may be of relatively highconductivity material produced by chemically reducing part of a barium titanate sheet, as described in Specification 672,227. Whichever element is used it is mounted as in Fig. 5 and a high polarizing voltage is temporarily applied from a source 30. This leaves the barium titanate portion in an electro-mechanically sensitive condition, while the other portion is relatively inert, this enabling the element to operate by bending. The polarizing voltage may be retained during operation.

Abstract: 931,520. Overhead ropeways. CENTINE E BLONDINS CRUCIANI S.p.A. Sept. 5, 1960, No. 30508/60. Class 78 (4). An overhead ropeway has two dollies 3, 4, Fig. 1, which move in unison, the blocks 13, 14 thereof being independently movable and supporting a hook 16. As described, the dollies 3, 4 are traversed by a winch 15 and ropes 17, 18 fastened together at 19. Winches 7, 8 and ropes 5, 6 raise and lower the blocks 13, 14 respectively. In a second embodiment, secondary dollies 19, 20, Fig. 3, are supported on ropes 21, 22 which are attached to the primary dollies 3, 4. The hook 16 is supported by blocks 13, 14 and ropes 5, 6 which each pass over pulleys on one of the primary dollies and both the secondary dollies. Operation of the winches 7, 8 simultaneously and in the same direction lifts or lowers the hook 16 vertically. If the rope 5 is wound in by the winch 7 alone, the dollies 19, 20 will move towards the dolly 3, the hook 16 being simultaneously lifted. As shown in Fig. 5, the ropes 1, 2 may be supported by derricks 23, 24, the derricks being braced by ropes 25, 26 having compensating weights 29, 30 suspended therefrom. Stays 27, 28 are also attached to the ropes 1, 2 and bear weights 31, 32. Fig. 6 shows a construction of runner. When the drawing rope 17 moves relative to the carrying rope 1 the pulleys 40, 41, which are urged into engagement with the rope 17 by a spring 37, drive a pulley 38 through a drive member 46, thus moving the runner along the rope 1.
