Title: Improvements in keyless locking mechanism
IPC: B60R25/021
Filed: 1920-01-03
Abstract: 161,264. Dougall, J. C. Jan. 3, 1920. Locks, permutation.-In keyless locking-devices for revoluble parts of mechanism, for example, the steering-post of a motor-car, the steering-post is provided with a plurality of bolts which are moved from the locked to the unlocked position by rotating their operating-spindles through half a revolution, the heads on the spindles being adjustable relatively to the spindles by the same amount so that any locking-combination is secured by reversing the heads of the selected spindles when all the bolts are in the unlocked position and then rotating the heads back to their normal position. In a casing embracing the steering-post tube, are arranged in annular fashion bolts 5 adapted to take into recesses 9 cut in the flange 8 of a member 3 fixed to the steering-post tubes. The member 3 also carries a flange 6 having peripheral recesses equal in number to the recesses 9 but staggered relatively to the latter. The bolts are operated by bits 24, Fig. 5, on the spindles 20 engaging with shoulders 18, 19 on the recessed portion of the body of the bolt. The bolt is held in its extreme positions by a spring 13 engaging in notches 14, 15, the spring being removed from the notches by a cam 25 mounted on the stem 20 and provided with opposite notches which permit the cam to rotate in one direction only. The reversible heads 32, Fig. 4, on the spindles are provided with flanged bases 38 having axial slots which engage with corresponding flats 30 on the stems 20 and project through holes in the casing top 35 on which are marked numerals or letters to indicate the combination. The heads 33 are further provided with radial indicators 40. In locking the device, the bolts are first moved to unlocked position, the heads of the selected bolts are reversed on their spindles, and the steering- post is moved to bring the recesses 9 into alignment with the bolts 5, incidentally bringing the projections 39 between the recesses 7 on the upper flange 6 into such a position that the heads can no longer be extracted for reversal. The heads of the selected bolts are finally rotated to bring the indicators 40 into their normal position pointing outwards.

Abstract: 978, 059. Automatic character reading. SYLVANIA ELECTRIC PRODUCTS Inc. Jan. 2, 1963 [Jan. 2, 1962], No. 281/63. Heading G4R. In a character recognition apparatus the character is sensed to produce a corresponding pattern of signals on an array of storage elements and the outputs from the store are transmitted to recognition circuitry by elongated solenoids connected each to a storage element and character circuits having loops inductively coupled to the solenoids so that the read out pulse in the solenoids causes signals in the character circuits. The storage elements may be cores 32, Fig. 2 which are set or not set according as to whether the corresponding point on the character is black or white. The solenoid 36 may be wound on a paper tube and it passes through holes in a series of plates 381-38n each relating to a particular character. As shown in Fig. 4A the plates may have serial connected coils of differing numbers of turns surrounding the several solenoids, the directions and weightings of the coils being designed to give the maximum signal from the plate corresponding to the character sensed. In the form of Fig. 4B to avoid the necessity of having coils of different numbers of turns, the cores 32 of the storage array may each be connected to a group of four solenoids, the winding density and direction of which is designed to give them the weightings 1, 2, 4 and and the coils, each consisting of one loop, embrace a selection of these solenoids so as to produce a weighting of any value between +7 and -8. There may be a number of output tags of which all are broken off except one. This facilitates making the connections when the plates are stacked together on the solenoids. The circuit may be printed. In the form of Fig. 4D the circuits are all printed in the same pattern and modified by breaking the loops on one side or the other as shown. Each bit is represented by two solenoids in this embodiment, weighted +1 and +3 respectively. The outputs of all the plates 38 are applied to a maximum signal detector consisting of a series of biased transistors, the first to conduct serving to cut the others off. A minimum value is set by a threshold level signal applied to all the transistors.

Title: Improvements in gas calorimeters
IPC: G01N25/42
Filed: 1923-01-05
Abstract: 210,950. Simmance, J. F. Jan. 5, 1923. Calorimeters.-In a gas calorimeter the gas is positively supplied at a constant volumetric rate, the heat of the products of combustion being absorbed by a stream of air the flow of which is induced and automatically controlled so as also to be constant. The burner 5 projects into a combustion chamber 1 surrounded by a chamber 2 through which the heat-absorbing air passes, the flow, of air being induced by a flue 3 containing a burner 8 for creating an up-draught. The gaseous products of combustion are expelled along a pipe 7 into the flue 3. The! air for combustion enters an aperture 6 after being saturated by passing over a number of strings &c. 28 which dip into water in a tray 30. The gas-supply means comprises two coaxial drums 12, 13, the latter acting as a motor for the former and being supplied with gas from a pipe 14. A branch 18 from the pipe 14 passes into water in a sealed tank 16 from the upper part of which an outlet pipe 19 leads to the drum 12. Also passing into the water in the tank 16 is a pipe 20 having openings 22 within the tank and a burner 21 at its upper end. The meter drum 12 is of the wet type and is provided with a pipe 24 for maintaining a constant level of liquid within it. The speed of the drums 12, 13 is controlled by a regulator 27. The tank 16 becomes warmed by conduction along the pipe so that the gas is saturated at a temperature somewhat higher than that of the surroundings and consequently a small quantity of water is condensed in the drum 12' when the gas is cooled. The pipe 20 also ensures that the gas within the tank 16 shall be at atmospheric pressure. The automatic control of the induced current of heat-absorbing air is obtained by a double valve 31 suspended from one arm of a lever 34 the other arm of which carries a counterweight 35. The valve is provided with a disc 32 within a cylindrical chamber 33, the disc moving in response to pressure variations to adjust the valve aperture. The calorific value of the gas is recorded by an arm 41 differentially operated by thermometers 36, 39, the former being within the flue 3. The gas and air supplies are brought to the same temperature by disposing the drum 12, the valve 31, and the thermometer 39 in the same stream of air. The chamber 33 may be provided with an adjustable additional air inlet and the valve device may beprovided with means, such as an aneroid chamber mounted on the lever 34, for automatic adjustment in accordance with pressure and temperature changes. The tank 16 may contain a device similar to the strings &c. 28 for ensuring saturation of the gas.

Title: Dewaxing of oils
Inventor: ROYDER THOMAS HARVEY
IPC: C10G73/02
Filed: 1960-01-06
Abstract: The dewaxing of lubricating oil fractions is effected at -10 DEG  to 120 DEG F. by flowing a solution of the lubricating oil in a precipitating-diluent solvent, chilled to a temperature at which a slurry of wax crystals is formed in the solvent, through an annular space across a filtering surface in a line filtration zone at a velocity of 5-15 ft./sec. so as to maintain a pressure drop across the filtering surface of 0,1-1 lb./sq. in./min., separating a dewaxed oil phase as a first filtrate from the line filtration zone, removing a concentrated slurry containing wax crystals from the line filtration zone and filtering it in a second filtration zone to form a wax phase and a second filtrate. The precipitatingdiluent solvent may be (a) a blend of a ketone (e.g. one or more of acetone, methyl ethyl ketone, methyl n-propyl ketone and diethyl ketone) and an aromatic material (e.g. benzene and/or toluene), (b) a blend of ethylene dichloride with one or more of benzene, chloroform and carbon tetrachloride or (c) a furfural/benzene blend.  The second filtration zone may be a rotary filtration zone and the second filtrate may be returned to the first filtration zone in admixture with additional solvent, if necessary, to recover additional amounts of dewaxed oils therefrom.  In both the line filtration zone and the rotary filtration zone, the filtering surface is suitably a cloth, such as one composed of nylon or cotton.  In a modification of the process, the chilled solution may be passed in series through a plurality of line filtration zones, dewaxed oil being recovered from the first filtration zone in the series, the filtrate from each of the succeeding filtration zones being recycled to the next preceding filtration zone and fresh solvent being added to the feedstocksolvent-wax slurry prior to the last filtration zone in the series.  The concentrated slurry fraction from the last of the series of line filtration zones may be warmed and passed through another line filtration zone and the resultant concentrated slurry from this final line filtration zone may be subjected to a rotary filtration operation.  Apparatus for carrying out the process of the invention is described, including means to prevent the choking of the line filter with wax (e.g. an oscillating solenoid-operated hammer which at least periodically subjects the filter to compression shock waves, means for periodically recovering the direction of flow of slurry or means for supplying a periodic back-wash of hot solvent).
