Title: Improvements in or relating to electric control apparatus for placing a load in a selected position
IPC: G05D3/16
Filed: 1945-01-04
Abstract: 615,411. Control apparatus. YARDENY, M. N. Jan. 4, 1945, No. 400. [Class 40 (i)] A motor driven selector for adjusting a tuning condenser to anyone of a number of pre-set positions comprises a number of contact arms 9 fixed to a common shaft 7 and an equal number of co-operating elements each consisting of an insulating disc 73 carrying a pair of conductors 1, 2 separated by a gap 5. The discs 73 are rotatably supported in slots 75 in the framework of the selector and are manually adjustable by means of friction washers 97, 98, Fig. 2A, on shafts 95 or by worm and gear arrangement as shown in Fig. 2B. The conductors 1, 2 which are mounted on the top surfaces of the discs 73 are electrically connected to external circuits through fingers 85, 86, which engage respectively conductors 1 and conductors 82 fixed on the reverse of the disc but electrically connected to conductors 2. The shaft 7 carrying the contact arms 9 is driven by a motor 200 through a train of gears including a gear wheel 116 loosely mounted on the shaft 7 and a friction clutch. The clutch comprises friction discs 120 and springs 134, mounted between the gear 116 and a disc 131 fixed to the shaft. The friction discs 120 are each provided with two peripheral recesses 123, 124, Fig. 4, which are engaged by two pins 132 extending from a disc .122 frictionally coupled to the gear 116. The arrangement is such that the rotation is transmitted first by friction, which changes the more direct drive as the discs slip successively to allow the pins to engage the edges of the recesses. In a modified clutch, Fig. 10 (not shown), one of the pins 132 is mounted on each of the discs 122, 131. There are no springs between the friction discs but the discs are forced together by external spring actions. The recesses on the friction discs are so arranged that alternate friction discs are coupled by one pin 132 to the disc 122, the remaining discs being coupled to the disc 131. The clutch may be replaced by a device Figs, 8, 9, resembling a universal coupling, the two parts 145, 146 of which are coupled by springs 147 and rods 148. The discs 116 and 131 may be temporarily locked by an electromagnetic device. The shaft 7 may be adjusted manually by means of a thumbhead 153 on a shaft 152. A pinion 151 on the shaft engages teeth 150 on the disc 131 which is fixed to the shaft 7. The frictional connection between the disc 122 and the gear 116 allows the shaft to be adjusted without disturbance of the gear 116. The shaft 7 may be coupled to the driving condenser through gears 136, 137 and a shaft 135. The Specification describes. an electrical circuit for use with the selector to control a reversible motor.

Title: Improvements in or relating to the production of anhydrous magnesium chloride
IPC: C01F5/32
Filed: 1944-01-11
Abstract: In the production of anhydrous magnesium chloride, mechanically strong shaped pieces or lumps containing oxidic magnesium compounds are prepared by mixing a pulverous material, e.g., magnesia with or without magnesite or megnesium oxychloride, containing at least 20 per cent. of hydraulically setting magnesia, with sufficient water relatively free from magnesium cholride to form a paste which can be formed into pieces of suitable size, the hardened pieces while still retaining substantially all of the added water being then chlorinated in the presence of a reducing agent, which may be incorporated with the magnesium compounds or be fed separately into the chlorination furnace, e.g., as carbon monoxide.  Chlorination includes the use of a gas containing chlorine or a suitable chlorine compound. Carbon, peat, sawdust, and salts such as sodium and potassium chlorides may also be included in the mix prior to chlorination. Specifications 259,498, 310,365, 333,741, [all in Class 1 (iii)], 480,698, 548,800 and 582,333 are referred to.

Title: Improvements in electronic voltage stabilizing apparatus
IPC: G05F1/52
Filed: 1946-01-08
Abstract: 601,144. Automatic control systems for eddy-current clutches. WINTHER, M. P. Jan. 8, 1946, No. 654. Convention date, May 16, 1942. [Classes 38 (ii) and 38 (iv)] A system for producing a stabilized D.C. reference voltage for use in an eddycurrent clutch electronic control device as described in Specification 601,143, comprises a valve in which D.C. control voltages are applied to both the control and screen grids, from a potentiometer associated with the D.C. circuit, the screen grid being connected to the cathode through a leak. In the embodiment shown, a D.C. potential is produced from-the A.C. supply line by a conventional double-diode rectifying circuit (not shown) and applied to the stabilizing circuit at point CP-2 and potentiometer P-9. In the beam power tube 6, the screen-grid SG is connected to the cathode KK through the cold-cathode discharge tube 12. A rise of applied D.C. potential, i.e. grid SG potential, increases the current through tube 12, causing a larger potential drop across potentiometer P-9 and hence a larger negative potential at grid CG, relative to cathode KK. Fluctuations in the current through anode A are thereby limited, thereby effecting a steady potential across output potentiometer P-10. The coldcathode tube 11 contributes further stabilization.

Title: Non-linear enhance system
Inventor: NINOMIYA YUICHI
IPC: H04N19/00
Filed: 1987-01-06
Abstract: PURPOSE:To remove the deterioration of the picture quality of a reproduced picture, due to the action of a low pass filter, with the aid of a simple constitution by giving a non-linear enhance onto the signal component of an intermediate and a high frequency band in the signal frequency band of a reproduced picture signal which has a narrower signal band width. CONSTITUTION:A non-linear enhance circuit 16 leads an inputted filter output moving image signal component to a band pass filter 19, and extracts only the intermediate and a high frequency band signal component, and leads it to a non-linear circuit 20. Then, the enhance is not given to the part of the low signal level and the high signal level of the signal frequency band, which is enhanced by the non-linear enhance circuit 16, but the enhance is given only to the intermediate and high frequency band signal component of an intermediate level, which can give the improving effect to the definition visually. When the enhance output signal of the non-linear circuit 20 is led to an addition circuit 21, and is added to the filter output moving image signal component, a visual bur is not produced even for a reproduced and displayed moving image with a little motion. Thus, the visual deterioration of the picture quality can be removed without complicating a signal processing.

Title: Displacement gauge
Inventor: IWAMOTO KATSUJI
IPC: G01F23/292
Filed: 1987-01-07
Abstract: PURPOSE:To take an analog measurement and to measure more accurate displacement by operating the ratio of reflected light from an surface to be measured to light emitted by a light source. CONSTITUTION:The light emitted by the light source 1 is projected on a liquid surface 5 and its reflected light from the liquid surface 5 is guided to a 1st photosensitive element 11 by an optical fiber for light reception and converted into an electric signal. The light emitted from the light source 1, on the other hand, is passed through an optical fiber 15a for light-emission side reference, guided by a 2nd photosensitive element 17, and converted into an electric signal. Then the electric signals of the 1st and 2nd photosensitive elements 11 and 17 are inputted to an arithmetic means 19, which performs subtraction and supplies its result to an output adjusting means 20 to find gaseous phase height (h), thereby measuring the level of the liquid surface 5 continuously. Thus, the displacement of the level of the liquid surface 5 is measured on an analog basis and fine displacement can be detected as compared with digital measurement.
