Abstract: 1,170,727. Electric selective signalling. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 30 Aug., 1968 [2 Sept., 1967], No. 41471/68. Heading G4H. A digital/analogue converter includes a ladder network 4 connected into the discharge circuit of a capacitor 3, successive pulses of, for example, a binary coded pulse train occurring at times T 1 , 2T 1  &c. being directed by a commutator 17 to successive branches of the ladder so that at a time T 2  after the last pulse of the pulse train the voltage across capacitor 3 represents the digital input signal. In the embodiment described the pulses from commutator 17 are applied to the bases of transistors 18 which then apply a constant current pulse to the associated junction of the ladder 4. The converter may be used in the feedback loop of an analogue/digital converter (Fig. 3) in which the sampled input signal, which may be a speed signal is fed to a capacitor 41. The voltage from capacitor 41 as it discharges is compared at times T 1 , 2T &c. with a reference voltage from a discharging capacitor 61, the comparator 64 controlling a pulse modulator 65 so that whenever at times T1, 2T &c. the reference voltage is less than the voltage from capacitor 61 a pulse is transmitted on conductor 40 and the associated brand of ladder network 42 is brought into the discharge circuit of capacitor 41 to reduce the voltage across it by an amount proportional to the binary weighting of the pulse. The pulse train on conductor 40 then represents the input analogue signal to amplifier 36.

Title: Printing system
IPC: B41B19/00
Filed: 1975-10-10
Abstract: 1477427 Controlling printers INTERNANATIONAL BUSINESS MACHINES CORP 10 Oct 1975 [11 Nov 1974] 41573/75 Heading G4H In printing, character coded data from a computer (not shown) is converted by a translate table 72 into graphic code bytes which address character generators 74 to modulate a laser beam (132) repetitively swept across an electrographic print drum (142) to build up the characters in a line of print in a succession of horizontal slices. There may be four translate tables 72 each associated with a respective set of 64 character generators so that four different fonts are available at any one time. The contents of the translate tables 72 and the character generators may be changed by the computer. Any unused translation addresses in the tables 72 are filled with an "unprintable character" error code. The same graphic code byte may be in several different positions in the tables 72 so that the same character may be printed in response to different character codes from the computer. In the preferred arrangement, the computer delivers 8-bit EBCDIC coded character bytes which are assembled into lines of up to 204 characters in a buffer 70. Each line is translated by a selected one of the four tables 72 to generate 8-bit graphic code bytes in which 2 bits select one of the 4 fonts and the other 6 bits one of the 64 characters in the selected font. After compression at 76 by dropping repetitions of like characters, the graphic code bytes are assembled in a page buffer 78 in which lines may be merged as in Specification 1,477,429, and character height and line spacing determined and blank lines inserted as in Specification 1,477,430. The output of the page buffer 78 is decompressed at 81 and minor modifications may be introduced at 82 to certain copies at specified positions of specified lines, details Fig. 8 (not shown). The character generators 74 are addressed for read out via 2 line buffers 83, 84, used alternately. They also receive character image data from the computer and addresses for write in and pitch bits from tables 72, the pitch bits being for selecting characters of different widths, as in Specification 1,477,426. Each character generator contains image data for modulating the laser beam to build up a character in up to 24 horizontal slices, each slice being stored as a pair of half slices each half slice having its own pitch bit and parity bit whereby characters of 12, 15 or 18 bits width are available. The full 24 horizontal slices are used for 6 lines per inch, slices 5 to 22 for 8 lines per inch, the selection of desired character height being as in Specification 1,477,430. The position of the start of each line of print and the length of the line are controlled as in Specification 1,477,428.

Patent GB-417712-A (GB)
Abstract: 417,712. Fluid - actuated valves. BOSCH AKT.-GES., R., 4, Militõrstrasse, Stuttgart, Germany. May 30, 1934, No. 16078. Convention date, June 9, 1933. [Class 135.] Valves controlled by pilot or relay valves.-A controlling device for gas-heated apparatus wherein variations in pressure produced in a pipe for control-gas act on a main valve in such a way that it is opened by an increase in pressure in the control pipe and closed by a decrease of pressure, has the controlling chamber of an adjusting-device for operating the main valve connected to a part of the control-gas pipe situated between the ignition or pilot valve and the pilot burner nozzle. A main valve 13 controlling the gas supply to a burner 12 is connected to a diaphragm 14 forming one side of a chamber 15 which is connected by a pipe 25 to a chamber 20. A control gas supply pipe 18 leading to the chamber 20 is normally closed by a valve 22 and the chambers 20, 15 vented to atmosphere through a pilot nozzle 23 formed in an expansible diaphragm 21. When the diaphragm 21 is heated by a match the valve 22 opens to supply the pilot nozzle and the increased pressure in the chamber 15 opens the valve 13. Failure of the pilot light causes the valve 22 to close and consequently also the valve 13. Fig. 2 shows a modification in which the flow of control gas is additionally controlled by a valve 36 influenced by the flow of water in a pipe 32 heated by the burner 12. A restricted passage 39 maintains the pilot jet when the valve 36 is closed. The expansible diaphragm 21 is separated from the chamber 20 by a partition 49 having small holes 50 to prevent excessive pressure on the pilot jet. An adjustable orifice 501 may also be provided in the partition. The under surface of the diaphragm 14 in this modification is open to atmosphere through an aperture 30 in a chamber 16<1>. Another modification is described in which a thermostat in the heated pipe shuts off the supply of control gas to the diaphragm 14 when the temperature reaches a maximum. When this occurs the pressures on the two sides of the diaphragm 14 are equalized through a permanently open but restricted passage which normally serves to supply an additional pilot jet, or both sides of the diaphragm may be vented to the main burner passage, the upper side through the restricted passage.

Relates to a vehicle torque transmission device of the parent Specification, wherein an hydrodynamic torque converter 34, comprising an impeller 36 fast with a bell casing 25 drivingly connected to an input, engine-driven, shaft 10, a turbine 39, and a reactor 42 reacting on a fixed support sleeve 16 through a one-way detent 43, is followed in series by a separating friction clutch 35 comprising driving support and spring-urged presser plates 44, 45 rotatable with the turbine 39 and a driven plate 47 splined on an output shaft 11 fast with a vehicle wheel drive pinion 12, the input shaft 10, the output shaft 11 and the sleeve 16 being concentrically nested. In such a device, the input shaft 10 has secured thereto by a taper fitting 23 and screw and lock-washer 24, 24a, a coupling element 21 which protrudes from the output shaft 11, has a spigot 30 on which the bellcasing 25 is centred, and is drivingly connected to the bell casing by a flexible diaphragm 26 disposed in the same transverse plane as the spigot 30, riveted at 27 to the element 21 and bolted at 28 to a ring 29 welded to the bell casing. The spigot 30, provided with a seal 31, engages a flange 32 of the bell casing, such engagement allowing slight relative angular displacement between the latter and the coupling element 21. The bell casing has a starter ring gear, and the coupling element 21 has integral therewith a pulley 22 driving a fan. dynamo or, if not directly driven, a clutch feed pump 66.  In operation, with a gear shift lever 63 released, to open a switch 64, and a switch 65 open, a de-energised electromagnetic valve 62 directs pressure oil from the pump 66 through a line 59, a space 14 between the shafts 10, 11, and passages 60 along the right hand inside of the bell casing, to a chamber 52, for friction clutch engagement, a line 61 being vented. When the gear shift lever is operated, to close the switch 64, or when the gear is in Neutral and the switch 65 is closed, the valve 62 is energized and directs pressure oil through the line 61 and a space 18 between the shaft 11 and the sleeve 16 to a chamber 54, for friction clutch disengagement, the line 59 being vented. The chamber 54 is connected to an outer chamber 53 by a passage 56 which is formed in the friction facings 48 of the driven plate and has a pressure loss greater in the direction 53-54 than in the direction 54-53 for slow progressive engagement and rapid disengagement of the friction clutch. The torque converter working circuit is connected to the chamber 52 by an impeller-turbine gap 55 and to the chamber 54 by a turbine-reactor gap 57 and a non-return valve 58.

Abstract: 1,088,857. Electro-static printing. EASTMAN KODAK CO. Oct. 16, 1964 [Oct.18, 1963], No.42238/64. Heading G2H. Electro-static images are prepared by placing an electrically insulating receiving sheet in overlying contact with the surface of a master having an image of electrically conducting and insulating surface areas carried on an electrically conductive support, electrically charging the outer surface of the receiving sheet to form an electrostatic image thereon, applying an electro-static developer to the charged surface of the receiving sheet and depositing a toner image thereon. The printing master may be prepared by exposing a charged photo-conductor layer on a conductive support and either (a) electrolytically developing image with a solution containing ions of Ag, Fe, or Ni to form a metal deposit on the image areas, (e. g. by using a viscose sponge containing a solution of 2-hydroxyethylamine/ethylene sulphide condensate, AgNo 3 , magnesium acetate, acetic acid and 2-diethylaminoethanol); or (b) developing with a powder having a different conductivity from that of the photo-conductive layer; in (b) the conductivity difference may be increased by storing the plate in the dark, and optionally heating by infrared or corona charging, the plate, to reduce to conductivity of the photo-conductor, or by exposing the plate to light to increase the conductivity of the photo-conductor. The electrostatic image on the insulating may be developed with a dispersion of lighographic ink in cyclohexane transferred to another sheet and/or fixed (e.g. by heat or pressure).

Title: Extraction of phenols from neutral hydrocarbon oils
Inventor: KOWALSKI GEORG
IPC: C07C37/72
Filed: 1958-12-31
Abstract: Phenols are extracted from tars, tar oils and other hydrocarbon oils by means of an amide, e.g. urea or acetamide, thiourea or guanidine. Addition compounds are formed between the phenols and the extractant. The extractant is advantageously employed in aqueous solution.  The extraction is improved by the addition of paraffic or naphthenic hydrocarbons.  In an example, a mixture of tar oil (containing 40% of phenol) and Fischer-Tropsch kogasin, which mixture had a boiling-range of 180 DEG -230 DEG C., was shaken for 5 seconds at 32 DEG C., with a solution containing 90 grms. of urea per 100 c.c. of water.  The mixture was then allowed to separate into two layers; and the raffinate was extracted, at 20 DEG C., with fresh urea solution. The raffinate was then free from phenol; and the extract contained no hydrocarbon or other impurities.  The addition compounds may be decomposed by heat into free phenols and recovered extractant.  The extractant solution may be purified by treating it with a solid of large surface area, e.g. activated carbon, bleaching - earth, ion-exchangers, silica gel and pumice; and a suitable apparatus for this purpose is described wherein active carbon is carried along in a stream of the solution.  In another embodiment of the process, the extractant is first used to extract aliphatics from a mixture of hydrocarbons boiling below 200 DEG C., and the extractant-aliphatic hydrocarbon addition compound is then used to extract phenols from higher-boiling oils.  The aliphatics remain in the dephenolated oil, and may be recovered therefrom by rectification.

Title: Aldehyde polymerisation process
Inventor: WARREN CHARLES KENNETH
IPC: C08G2/28
Filed: 1962-06-12
Abstract: A polymeric aldehyde is prepared by polymerizing at least one aldehyde in the presence of a polymerization initiator at a temperature below that at which the initiator would also act as a catalyst for the degradation of the polymer so formed and the initiator is thereafter rendered ineffective as a catalyst for such degradation, the initiator being the product of reacting together equimolar amounts of a N,N-dihydrocarbon substituted amide and a hydride or hydrocarbon derivative of an element of Groups Ia, IIa, IIIa and IVa (other than carbon or silicon) of the Periodic Table according to Mendel<\>aeeff.  The polymerization may be effected in the presence of acid contamination provided the amount of acid present does not substantially exceed 3 moles per mole of initiator. After the polymerization and before allowing the product to warm up, the initiator is either extracted with a suitable selective solvent or a weak acid is added, if sufficient is not already present, to render it ineffective as a degradation catalyst on raising the temperature to that at which degradation of the polymer would normally occur.  Aldehydes specified are formaldehyde, acetaldehyde, propionaldehyde, n-butyraldehyde, n-valeraldehyde, iso-valeraldehyde, n-caproaldehyde, cyclohexaldehyde, 2-ethyl hexaldehyde, benzaldehyde and phenyl acetaldehyde.  The polymerization may be effected in organic solvents that are liquid at the temperature of the polymerization and a number of these are specified.  In the examples, the monomers used are acetaldehyde and n-butyraldehyde in the presence of acetic acid and butyric acid respectively, the catalysts being the reaction products of aluminium triethyl with either dimethyl formamide or tetramethyl urea, the solvents toluene alone or mixed with methyl cyclohexane.  The polymerization is effected at -78 DEG  C., and is terminated by adding n-butanol and acetone before allowing the mixture to warm up to room temperature. Thermal instability of the polymers may be reduced by reacting the polymer with compounds to replace its terminal hydroxyl groups with more stable groups such as carboxylate, by etherification or by the heat treatment described in Specification 980,516.  The polymers may be formed into shaped articles such as films, sheets, fibres and filaments. Conventional composition additives may be incorporatedALSO:Catalysts, used for the low temperature polymerization of aldehydes (see Division C3), are made by reacting equimolar amounts of a N, N-dihydrocarbon substituted amide and a hydride or hydrocarbon derivative of an element of groups IA, IIA, IIIA and IVA (other than carbon or silicon) of the periodic table according to Mendel<\>aeeff.  In the examples either dimethyl formamide or a toluene solution of tetramethyl urea are added to a solution of aluminium triethyl in a mixture of cyclohexane and toluene.

Title: Method of and safety apparatus for protecting occupants of a moving vehicle
IPC: G01S13/931
Filed: 1970-09-09
Abstract: 1326207 Radar TOYOTA JIDOSHA KOGYO KK 9 Sept 1970 [8 Oct 1969(2)] 43255/70 Heading H4D [Also in Division B7] A method of protecting occupants of a moving vehicle upon collision with an obstacle comprises sending radio signals having a first frequency from the vehicle; receiving in the vehicle signals, having a second frequency, reflected from the obstacle; producing first and second electrical quantities which are proportional, respectively, to the difference between the two frequencies and to the amplitude of the received signals; and multiplying the two electrical quantities to produce an actuating signal when their product exceeds a set value. The actuating signal is utilized to activate protecting means in advance of the actual collision, for example, bags which when inflated prevent occupants being thrown against the interior of the vehicle. As described, a moving vehicle 100, Fig. 3, is provided with a transmitting and receiving aerial 3, having a beam width of α. A second vehicle 200 is a head of the vehicle 100, the distance between the two vehicles being D, and their relative velocity V. The received reflected signals are directed, together with some part of the signal from the transmitter 1, Fig. 1, to a mixer 4 by means of a directional coupler 2. The output, at the Doppler difference frequency, is amplified and is split between a detector 7 and a frequencyto-voltage converter 6. Output voltages from the detector 7 and the converter 6, which are proportional, respectively, to the amplitude and the frequency of the Doppler signal, are multiplied together by a multiplier 8, whose output is applied to a Schmitt circuit 9. When the input to the circuit 9 is sufficient, an actuating signal is delivered to an operating means 10, which allows gas from a container 11 to inflate a bag or bags 12. A circuit 6<SP>1</SP> may be provided between the converter 6 and the multiplier 8, to block signals below a pre-determined level, corresponding to a low relative velocity of the vehicles. Similarly, a circuit 7<SP>1</SP> may be provided between the detector 7 and the multiplier 8, to block signals above a predetermined level, corresponding to a small distance between the vehicles. The container 11 may contain a non- inflammable gas under pressure, and the means 11 may be a valve. In one form of valve, an insulating partition is fixed in a connecting pipe to the bags 12 by a ring of fusible metal, which can be melted by an electric current, when the actuating signal is received (Figs. 7a, 7b, not shown). In another form of valve, a partition is destroyed by the explosion of a charge (Fig. 8, not shown). Alternatively, gas may be produced within the container 11 by the combustion of a suitable material (Fig. 9, not shown). The inflatable bags may be arranged in positions around an occupant of the vehicle (Fig. 6, not shown).
