Abstract: 914,308. Valve and transistor amplifying and gating circuits. BUSH & RANK CINTEL Ltd. April 14, 1959 [April 15, 1958; May 8, 1958], Nos. 11937/58 and 14741/58. Class 40 (6). [Also in Group XL (b)] A circuit for improving the signal/noise ratio of a signal having a frequency which may vary within a predetermined range, comprises a number of selector elements having narrow frequency responses to which the signal is applied simultaneously; and non-linear circuit elements each fed with the output from one selector element, so arranged that, in a common output circuit the ratios of the signal components which traverse different selector elements are increased from the ratios existing at the inputs to the selector elements. In one embodiment, Fig. 1 (the first Provisional Specification), the input signal is fed simultaneously to eleven channels each containing a band-pass filter 4, 5, 6, tuned to a different part of the frequency spectrum in which the signal falls, a rectifier 8 a valve, e.g. 10, and an output tuned circuit 11, 12, 13. Assuming the signal falls within the passband of the first channel, diode 8a will rectify part of the signal to produce a forward bias for valve 10a. The potential developed across the common cathode impedance 14 will increase due to the increased current and will bias the valves in the other channels more negatively to reduce their gain, so that only the first channel is operative to produce a signal in the common output circuit. The input connections to adjacent input transformers 3a, 3b (or the output connections from adjacent output transformers) are reversed so that when a signal lies between two channels and is transmitted by both, the resultant outputs are in phase. The valves may be replaced by transistors. In a second embodiment (see Group XL (b)) the electrical circuits are replaced by vibrating reeds and an optical system.

[Also in Division A5] A ear piercing apparatus comprises a hollow needle 12 bent into a press button at its proximal end 28, a slotted tube 14 attached to an ornamental ball 16, and an auxiliary cutting tube 15 sleeved over the distil end of the needle. In operation a plastic anvil 21 is held against the inside of the ear lobe 22, the push button is pressed and the needle penetrates the lobe cutting a passage entered by the tubes until the ball engages the outside of the lobe. The anvil, the auxiliary cutting tube and the needle are then removed leaving the slotted tube 14 and the ball 16 on the ear. A ear-ring is then formed by securing a ball fastening 18 to the free end of the slotted tube. The bore of this ball fastener may be lined with rubber or friction gripping material. The slot in the tube is longer than the width of the ear lobe to allow air to the ear hole so quicken the healing of the punctured surface and promote drainage in cases of infection. A rod 20 is provided for cleaning out the bore of the tube. This is done after the ear rings have been worn for a length of time. If the ball fastener is removed, a rubber squeeze bulb 44 with an outlet 46 containing a medicament or perfume 48 may be placed over the free protruding end of the slotted tube and liquid forced through the elongated slot (Fig. 10). While squeezing the bulb the opening in the ball 16 may be closed by a finger.

Abstract: 271,450. Naamlooze Vennootschap Nederlandsche Seintoestellenfabriek. May 22, 1926, [Convention date]. Thermionic generators.-Relates to valve transmitting systems in which the coupling between the grid, plate, and aerial circuits is designed to prevent oscillation hysteresis or instability arising from inherent tendency of such systems to produce two distinct " coupling oscillations." According to the invention the actual coupling coils C. D, E, Fig. 1, comprise only a small part of the total inductances included in the respective circuits. The winding direction of the coil E is so chosen as to increase the reaction effect for one wavelength whilst opposing that for the second wavelength, so that the system as a whole tends only to produce the former. Preferably the coil D is arranged to rotate within the coil C, as shown in Fig. 2, whilst the coil E is mounted to move relatively to the first two coils. As the coupling-coils form only a small portion of the total circuit inductances, they need not be changed when the operating wavelength is varied.

A property, such as adhesion of a metal coating to a metal backing is measured by passing an energizing current through the surface of the coating between a pair of energizing electrodes 47, 48, Fig. 5, contacting the surface of the coating, and measuring the voltage drop between a pair of detector electrodes 51 contacting the coating at points between the two energizing electrodes, by means of a transistor chopper amplifier connected to the detector electrodes 51 and to a meter. The two pairs of electrodes are arranged to contact the material before the full energizing current is switched on, either by use of a push button 37, Fig. 3 (not shown), on a probe carrying the electrodes; or by means of a relay, the normally open contacts 46 of which are connected, in parallel with a high resistance operating coil 50 of the relay, in one energizing electrode supply lead, and a hold-in coil 49 of which is connected in the other energizing electrode supply lead. With the latter arrangement only a small current flows when the electrodes contact the surface, sufficient to operate the relay which is then held operated by the coil 49, so that the contacts 46 remain closed to carry the full energizing current. The electrodes extend in parallel relation from the hand probe 27, Fig. 3 (not shown), but are pivotable about bearings (30) in the handle (27).
