An inert diluent may be present in both the chlorination and dehydrochlorination stages.
Patent GB-924396-A (GB)
Title: Automatic data accumulator
IPC: G07C3/14
Filed: 1960-10-13
Abstract: 924,396. Electric digital-data-storage apparatus. GENERAL ELECTRIC CO. Oct. 13, 1960 [Oct. 27, 1959], No. 35107/60. Class 106 (1). Apparatus for co-ordinating data derived at different times from a plurality of sources comprises delay means individual to the data channels deriving from each source, said delay means introducing a differential delay such that data relevant to a particular item can be arranged adjacently. The invention is applied to a steel mill in which a plurality of fault detecting means are arranged to inspect tinplate as it is being wound into a coil. A magnetic drum is employed in a delay circuit, the drum also being employed in a data processing circuit and as an output buffer store. The tinplate 4 is inspected by detectors 1, 2, 3 spaced apart in the direction of motion of the tinplate so that inspection data from the same portion of the tin-plate is produced at different times. The data is subject to differential delay in circuits 6 which comprise a magnetic drum track, so that data for the same tin-plate portion can, after processing, if required, in circuits 11, be arranged adjacently in a store 10 which is on the same magnetic drum. When the tin-plate is to be sheared at 8, a circuit 12 causes the data for the section of tinplate cutoff to be transferred to a buffer store 14, also on the same magnetic drum, prior to output recording by a printer 16. Fig. 2 shows the delay arrangement comprising a magnetic drum 18 from which data is read by a head 227, and after passing through a delay loop SDL, recorded in an opposite section of the drum track by a head 234. If desired, a gate 230 is enabled and data can recirculate without delay, over a loop RL. Data read from a cell in one sector, say 225, of the drum being recorded in the corresponding cell of the opposite sector 226. Each pair of sectors has a total number of cells corresponding to the delay required in the associated data channel. To operate the delay circuit a gate 245 is enabled instead of the gate 230. A " 1 " bit read from the drum is stored in a buffer flip-flop 229 and gated to a delay flip-flop 247 whence it is gated via a gate 250 enabled by a pulse on a line 704 derived from a tachometer generator 7, Fig. 1, which generator is driven in accordance with the movement of the tin-plate 4. The gate 250 feeds a buffer flip-flop 251, the output of which is fed via the gate 245 to the record head 234 to record the " 1 " but in the cell next to the one corresponding to the cell from which it was read. New data may be entered over a line 707 into the first cell of a drum sector. When the data has been shifted along a sector, resulting in the required delay, it is read out over a line 710 one bit from each of the three drum channels being transferred to a threebit shift register, the contents of which are transferred in parallel to a data accumulating section of the drum.

Title: Seismic playback/monitor system
IPC: H03K6/00
Filed: 1972-07-27
Abstract: 1363346 Producing visible displays from digital signals TEXACO DEVELOPMENT CORP 27 July 1972 35127/72 Heading G4H [Also in Division H4] A visible display of reduced amplitude is produced from a set of digital words representing the equation: analogue value = AR<SP>-E</SP>, where R is constant and the digital word has some bits representing A and some E. A periodic reference signal Vref having a maximum and a minimum value is generated and is used to change a digital signal representing a number K each time Vref reaches a maximum. The signal representing A is converted to an analogue signal V (D-A)  using Vref as reference voltage. This signal is amplified by a factor R<SP>(K-E)</SP> and the values produced by a series of conversions are displayed on an oscillogram or oscilloscope. The arrangement may be used for displaying seismic data. As described, the value of R is 8. The digital words are entered into register 20 and the part representing A is converted to analogue value V (D-A)  using Vref as reference voltage. The reference voltage generator has a sawtooth output varying from 1 to 8 volts and each time it reaches 8 volts, the value of K in counter 26 is changed by unity. The value E from register 20 is subtracted from K at 24 and the difference (in 3-bit binary) is decoded at 60 and is used to operate one of switches S1-S5. These switches select different numbers of 8 gain amplifiers 50, 52, 54, 56, 58 so that when V (D-A)  is applied to the input of the amplifiers V (D-A)  8<SP>(K-E)</SP> is generated at the output. This voltage is then demultiplexed (if several sets of values are being treated together) at 30, applied to hold circuit 32, filtered 34 and applied to oscillograph 36; successive conversions permitting the build-up of the required waveform. In alternative embodiments, the reference signal generator may produce an exponential or a third order function instead of a linear ramp or automatic gain control may be used.

Abstract: 1,222,735. Injection moulding. GLOBEUNION Inc. 25 July, 1968, No. 35512/68. Heading B5A. Partitioned battery cases with relatively thin walls of substantially uniform thickness are injection moulded in a stationary mould part 20 with a rectangular face 21 defining the bottom wall of a mould cavity in the shape of a battery case. The cavity is formed by two sets of cores 40, 41 respectively within the part 20, and four members 51, each member slidable on the part 20 on a rod 52 and urged outwardly by a spring 53. The cores 40 extend from a plate 60 urged upwardly against a stripper plate 61 by a drive plate 90; the cores 41 extend from a plate 64 connected to the stripper plate by two hydraulic cylinders 67. In the moulding position, members 80 on the plate 61 engage projections 82 on the members 51, and pins 31 extend into core recesses. Material such as polyethylene, polypropylene or polystyrene is then injected through nozzle 26 and fed to the cavity via runners 22 and heated heads 23, and whilst it is still in liquid state the pins 31 are retracted to bring their ends flush with the face 21 enabling the spaces previously occupied by the pins to be filled. After a cooling period the plates 60, 90 and cores 40 are lowered and when the plate 60 reaches stops 72 the plate 64, cores 41 and plate 61 are lowered. The latter plate carries the members 51 away from the mould, the inner faces of which move perpendicularly away from the sides of the moulded case. The case is returned on the cores 41 until it has hardened whereupon the cylinders 67 are actuated to cause the plate 61 to strip the case from the cores. Each core 40 has two air passages 46 to assist its removal.

Title: Electric current-producing cell and method of producing current using the same
Inventor: MINNICK LEONARD JOHN
IPC: H01M6/14
Filed: 1953-12-24
Abstract: 794,970. Batteries. CORSON, Inc., G. & W. H. Dec. 24, 1953, No. 35866/53. Class 53. An electric cell having two separate electrolytes comprises an anolyte and a catholyte each consisting of a salt dissolved in anhydrous liquid ammonia, the cation of the salt in the anolyte being the metal of the anode and the cation of the salt in the catholyte being ammonium or a metal which develops a potential at least 0.75 volts less than the anode metal, as measured in liquid ammonia. The anode 3 and anolyte 10 are separated from the annular cathode 6 and catholyte 11 by a permeable partition 9. The anode may be of Li, Na, K, Cs, Rb, Ca, Sr, Ba, Mg, Zn, Al, Be or Mn, and in one example a lithium anode in the form of a paste with ammonia is described with lithium thiocyanate in the anode compartment. In another example the anode is of metallic sodium with sodium thiocyanate in ammonia as an anolyte, and in both cases the catholyte consists of ammonium thiocyanate in ammonia. The cathode may be of Pt, C, B, Zr, W, or Ta or may correspond to the cation of the catholyte, where a metal salt is used. With NH 4  as the cation of the catholyte, H 2  is released during discharging and N 2  during changing. The anolyte may comprise a perchlorate, fluoborate, cyanate, nitrate or nitrite. A minor amount of a liquid amine (e.g. methylamine, ethylamine or pyridine) or of methyl cellulose may be added for some purpose such as reducing sludge. To avoid spilling the electrolytes may be mixed with an absorbent mass such as glass fibre. The lithium cell produces a potential of about 2¢ volts, with a current density of 20 mA. per square inch, but other cells produce potentials up to 4 volts. The cell is especially suitable for low-temperature operation, with improved efficiency, but can be used up to 50‹ C. if refrigerated or under pressure in a strong jacket. The freezing point of liquid ammonia (- 77‹ C.) is lowered by the electrolyte salt and this increases the low temperature range of the cell. Normally the electrolytes are separated only by a semipermeable diaphragm but for storage one may be in a sealed capsule.

Abstract: 847,143. Colour photographic materials. ILFORD Ltd. Oct. 31, 1958 [Nov. 18, 1957], No. 35919/57. Drawings to Specification. Class 98(2) Preparation of such materials involves mixing a silver halide emulsion containing a coloursensitising dye and a solution of a colour coupler or other compound, the tendency of which is to reduce the sensitivity of the emulsion at the site of a coating device and immediately coating on to a support immediately setting by chilling and rapidly drying to avoid the desensitising action of the coupler or other compound while the mixture is in the liquid state. Continuous feed into a mixing device and then to a coating device which avoids appreciable run-back of the mixture from the coating head or which extrudes the mixture on to the support is preferred. The method is particularly suitable for the red-sensitised layer of multilayer film, to which an example is directed, and a mixing device for the purpose is described and illustrated. Specification 625,992 is referred to.

The coating may subsequently be levelled by post heating.  The stream of fluidized particles preferably has laminar flow characteristics and the article to be coated may be pre-heated to a temperature not less than the melting point of the fusible material.  The material drains off through vacuum shoes 50 or through an exhaust vent 32 in the coating chamber 18, is recirculated, and the process e.g. as applied to electric motor stators or rotors may be continous (Fig. 1 not shown) with the articles to be coated conveyed on an endless chain past or through loading, pre-heating, coating, post heating, coating, post heating, quenching and unloading stations or chambers.  The technique may be applied to the coating of wire, pipe and metal containers with copper, lead, zincortin.  The method may also be used in conjunction with electrostatic charges which are applied to create voltage differences between the delivery nozzles and surfaces to be coated.

Abstract: 742,519. Sanitary closets. McDONALD, J. L., MAYNE, N. L., and MAYNE, G. C. Dec. 29, 1953, No. 36028/53. Class 26. A closed system sanitary unit comprises a bowl connected to a settling tank, means for drawing clear liquid from the settling tank to effect flushing of the bowl, separate rotatable means for agitating the contents of the settling tank to effect disintegration of the solid matter therein, and means for sealing and opening the discharge outlet of the bowl. When in use, pressure on the seat 27 is transmitted to the arm 20 through the arm 29, thus opening the ball valve 18 and enabling excreta to pass from the bowl 7 into the settling tank 9. A time delay switch is then operated and the electric pump 32 is brought into action to pump clear liquid, which has filtered through the partition 46 and gauze screen 44, into the bowl by way of the cylinder 51 and pipe 53. The weight of the liquid acting on the piston 55 causes the ball valve, which closed when the pressure on the seat was removed, to open, thus allowing the flushing liquid to pass from the bowl into the settling tank. Prior to discharging the contents of the settling tank through discharge pipe 13, any solid matter which has not disintegrated under the action of the chemical solution added to the water in the settling tank before use, is broken up by the radial cutter blades 37 which are actuated by engaging the shaft 36 with the pump shaft 35 by means of clutch 42. The settling tank is then refilled with fresh water to which some disinfectant and/or deodorizer has preferably been added. Two modifications of this unit are described, one being adapted for manual operation and the other incorporating a cistern for storing the flushing liquid.
