Abstract: 189,425. Western Electric Co., Ltd., (Assignees of Merrill, F. W.). Nov. 25, 1921, [Convention date]. Centrifugal switches.-A fixed disc 25 of nickel is adapted to be engaged by a number of tungsten contacts 20 mounted on an arm 15 carrying an overhung weight 19. The arm 15 is supported by spring blades 11, 11<1> attached to a disc rotating with the motor shaft 3. A counter weight 21 on the disc 5 is bevelled as shown to throw off dust. The disc 25 and the arm 15 are electrically connected to carbon brushes 29, 35 respectively, and when employed with a shunt-wound motor as shown in Fig. 4, contact between the points 20 and the disc 25 short-circuits a resistance 42 in series with the shunt winding 41 of the motor. The arm 15 is provided with holes 39 to which the contacts 20 may be transferred, thus reversing the action of the device, the contacts being then opened instead of closed by an increase in speed. The device is applicable generally, as an engine, motor or voltage regulator. The distance between the contacts is adjusted by a screwed member 4, and an extension 36 of the shaft 3 is provided with a recess 38 to facilitate its connection with a speed indicator.

Title: Information transmission system
IPC: G08B17/00
Filed: 1975-06-16
Abstract: 1476261 Alarm systems ABOYNE PTY Ltd 16 June 1975 [18 June 1974] 25631/75 Headings G4H and G4N An information transmission system comprises: (a) a transmitter arranged to transmit in two modes viz. a monitoring mode wherein monitoring signals of duration #t spaced apart by time t (greater than #t) are employed to modulate a carrier, and an alarm mode in which the carrier is modulated by alarm signals having a greater repetition rate than the monitoring signals, (b) a receiver which detects a change in the mode, and also if no signal with the duration 8t is detected within each period of successive predetermined (fault detecting) periods of time xt (greater than t). As disclosed, the monitoring and alarm signals are identical, each being a 600-microsecond multi-bit message in diphase form frequency-modulated on to the (RF) carrier, the monitoring mode involving repeating this message once per minute indefinitely and the alarm mode involving repeating it once per 800 microseconds (i.e. with 200 microsecond gaps) twenty times. A multi-storey building has a number of transmitters and a receiver, on each floor, communicating by radio, the receivers being coupled by cable to a control unit (with display) for the building which is connected by transmission line to a fire control authority station. A transmitter switches from monitoring mode to alarm mode on detecting fire (temperature or smoke). The message specifies the building, floor and sensor identities and includes a parity bit and extra bits. At a receiver, the received message is demodulated with signal duration and interval checks and fed to a shift register with a parity check. The message is rejected if it does not contain the correct building and floor identities and extra bits, and have correct parity. For monitoring, the sensor identity is decoded to set a respective sensor presence flip-flop. Every ten minutes these flip-flops are reset, and those which were not set in the previous ten minutes set respective sensor fault flip-flops to light respective fault lamps. The transmitters are battery-driven; fault may be flat battery. In the alarm mode, the sensor identity is compared with that in the previous message, equality setting a fire flip-flop respective to the sensor identity (as decoded), each fire flip-flop controlling a respective fire lamp (the two messages compared must occur within a predetermined period less than t). Ranges of values for the various intervals and durations are given, those above being merely preferred. Application to security and pollution level detection is mentioned.

Title: Method of modifying a semiconductor device
IPC: H01L29/00
Filed: 1965-06-21
Abstract: 1,089,076. Semi-conductor devices. INTERNATIONAL BUSINESS MACHINES CORPORATION. June 21, 1965 [June 29, 1964 (2)], No. 26073/65. Heading H1K. The voltage/impedance characteristic of a semi-conductor device having a layer of insulating material overlying a body of semiconductor material is lastingly altered by heating the device and subjecting it to an electric field which crosses the boundary between the insulating layer and the semi-conductor body, the alteration persisting when the device has been cooled and the field removed. The field is applied by means of an electrode (which may be added for the purpose) mounted on the insulating layer, which may be of silicon dioxide or of a lead-alumino-borosilicate or zinc-aluminoborosilicate glass, and the changing impedance may be monitored by passing current between two of the normal operating electrodes of the device. Details are given of such methods for effecting various alterations in the characteristics of diodes, PNP and NPN transistors, fieldeffect transistors, and capacitors, and of resistors included in monolithic integrated circuits. The value of a resistance may be altered in this way at different times during the operation of a circuit.

Title: Process for removing carbon dioxide from gaseous mixtures
IPC: C01B32/50
Filed: 1959-07-29
Abstract: Carbon dioxide is removed from gaseous mixtures by absorbing at below 60 DEG C. in an aqueous solution of a salt of an amino carboxylic or amino sulphonic acid capable of forming a carbamic acid with CO2, regenerating the loaded solution until the quantity of CO2 remaining therein is not greater than the value characterizing the position of the sharp bend in the curve of CO2 equilibrium partial pressure above the solution at the regeneration temperature against CO2 concentration in the solution, and does not differ from that value by more than 0,1 mol. CO2 per mol. salt, and absorbing CO2 from further gaseous mixture in the regenerated solution to an amount from 0,5-1,1 mols. CO2 per mol. salt.  Absorption and regeneration may be carried out continuously.  The position of the sharp bend is the position on the isotherm curves where the second differential of pCO2 is a maximum.  Salts may be alkali metal, e.g. Na and/or K, salts of taurine, N-methyl taurine, N-methyl d -amino propionic acid, glycocoll, sarcosine, a -alanine, N-(b -ethoxy)-taurine, or N-(b -amino-ethoxy)-taurine, ox compounds of formula R-NH-R2-X-M, where R, is an H atom, or branched, or unbranched, or cyclic aliphatic radical which may contain an amino group, or an alcoholic, or ether oxygen, X is a -CO2- or -SO3-group, R2 is a branched, or unbranched, or cyclic alkylene radical having at least 2 C. atoms, and M is the cation of an inorganic or organic base.  R1 preferably contains at most 8 C. atoms, e.g. methyl-cyclohexyl, cyclohexyl, hexyl, isobutyl, 2:5 dimethyl hexyl, propyl, ethyl, or methyl radicals.  The solution may be 3,5-4,5 molar and may contain free amino acid, e.g. up to 25% to displace the position of the sharp bend to lower loadings.  The acid may be the same as that in the salt, and may be produced by adding H2SO4 or HCl to the salt solution.  Absorption may be under super-atmospheric pressures, e.g. up to 30 atms., and gas mixtures treated may be those containing 20% or less CO2, particularly those resulting from other scrubbing, e.g. with hot potassium carbonate. The regeneration may be with steam, which may be produced by boiling the solution, although steam may be introduced at a rate equal to that at which it is carried off with CO2.  A gas inert to the solution, e.g. N2, H2, or air, may also be used to desorb the CO2, or subatmospheric pressure may be applied. Any of these methods of regeneration may be applied in association, preferably in stages with successively increasing temperatures, the last stage being 10-60 DEG C. higher than preceding stages.  Other gases, e.g. acetylene or olefins dissolved from the mixture may be removed in the initial stages by an inert gas and/or by subatmospheric pressures, e.g. at 20-30 DEG C. below the boiling point of the solution under atmospheric pressure.  With regeneration in a number of stages the pressure should not exceed atmospheric pressure throughout.
