Title: Method of Recovering Silver Halide from a Waste Solution
IPC: G03C5/395
Filed: 1967-06-19
Abstract: 1,192,445. Recovering silver halide. FUJI SHASHIN FILM K.K. 19 June, 1967 [24 June, 1966], No. 28194/67. Heading C1A. In a method for recovering silver halide, an aqueous dispersion containing silver halide and gelatin, which forms the waste from a washing stage in the production of light-sensitive materials, is allowed to stand in a reservoir until the gelatin is substantially decomposed by a fermentation reaction with bacteria present in the air, prior to the addition of a coagulant, such as aluminium- or zinc sulphate, ferric sulphate or ferric chloride. The standing time is generally from 10 to 20 hours at 10‹ to 40‹ C. The precipitate formed contains silver halide, coagulant and some gelatin and is separated from the supernatant liquid and processed in a known manner. In the example, silver bromide is recovered.

Title: Improvements in apparatus employing resonant circuits for interaction between train and track
IPC: B61L3/12
Filed: 1930-09-23
Abstract: 364,016. Track apparatus for interaction with moving trains. JACKSON, L. MELLERSH-, 28, Southampton Buildings, London.-(Vereinigte Eisenbahn-Signalwerke Ges.; Siemensstadt, Berlin.) Sept. 23, 1930, No. 28458. [Class 105.] In track apparatus systems using interacting resonant circuits in which two or more such systems are employed, the coils are arranged so that the fluxes emanating from one system and linking with the other system are cancelled therein. The systems may be tuned to different frequencies or to the same frequency. The arrangement shown in Fig. 1 comprises one circuit with a generator 9, windings 5, 6 on separate cores 1, 2, a condenser 11, and a relay 10, the circuit being tuned to a frequency f<1>. A second circuit tuned to a frequency f<2> similarly comprises a generator 12, condenser 14, relay 13, and windings 7, 8 on the two separate cores 2, 1. The winding 5 is traversed by flux from each of the windings 7, 8 which fluxes are however such as to. cancel each other, yokes being provided, if necessary, between the cores 1, 2. The interfering fluxes similarly cancel in the other windings. The co-operating circuit, Fig. 2, may be tuned to a frequency f<1> or f<2> by a switch 18 inserting a second condenser 17, or by means of a switch 19 the circuit may be rendered ineffective to actuate the relays. The inductance may be varied by tappings to switch contacts. The co-operating system may be a double-circuit one with the windings arranged as in Fig. 1 and in this case three signal effects can be given according as one or the other or both relays are actuated. A train may give a signal corresponding with its speed by means of a centrifugal device driven from the wheel axles which is arranged to switch in the appropriate circuit. By increasing the number of cores and coils higher multiple signalling may be effected, for instance to give a signal at a level crossing where trains travelling at different speeds must give the signal when they reach different distances before the crossing.

Title: Improvements relating to the manufacture of knitted fabrics
IPC: D04B1/06
Filed: 1952-11-12
Abstract: 746,756. Knitting. NEBEL, M. Nov. 12, 1952 [Nov. 12, 1951], No. 28464/52. Class 74(2). A rib fabric is produced on a rib machine and the needles are so operated that two yarns fed and knitted separately form a structure in which the loop formation in any needle wale is of a four - course sequence. In each wale the two yarns a, bare successively knitted to form a short loop B, a long loop A and a double loop D, the two yarns a, b forming the double loop D in each wale extending to the adjacent wales where they are separately formed into the short loop B and long loop A. In addition, the long loops may be held and knitted together with the succeeding double loop to form a tuck stitch as indicated at R/H. Alternatively, the long loop may be cast off the needles before taking yarn to knit the double loop, this arrangement providing an openwork fabric. Also, between each sequence of courses, a row of normal stitches may be knitted. The method of forming the fabric involves a two-bed latch needle machine in which the needles are at right angles to each other and in which in order to form the short loops B, the yarn is drawn about that portion of the needles of the other bed that extends between the hook and latch.

Class 122(i) [Also in Group XXVII] In a two-stroke engine with mixture scavenging and precompression of the mixture inside the crank casing, and comprising a piston 1 the skirt of which embodies two oppositely disposed transfer ports H that register, when the piston is at B.D.C. with transfer passages 6 leading to the scavenging and admission ports in the cylinder 5, the hollow interior space of the piston is sub-divided by a transverse wall 2 disposed at the height of the upper edge of the transfer ports H in such a manner that a restricted opening is left through which the space between the end wall of the piston and the transverse wall 2 is in communication with the remaining interior piston space and with the crank case space. Two restricted openings are provided, each being formed between the inner end of a transverse wall 2 and one of two projections 4 on the small end of the piston rod 7. At-slow engine speed and on the working stroke some of the compressed mixture flows through the apertures into the upper piston space so that only a part thereof enters the engine, whilst at high speed, little or no mixture enters the upper piston space so that substantially all the mixture from the crankcase is used for scavenging and charging purposes; the under side of the walls 2 are so inclined as to smoothly deflect the mixture into the transfer passages 6. The walls 2 may be dispensed with and the projections 4 extended, the apertures being formed between the inner piston skirt and the projections.

Filed: 1968-06-18
Abstract: 1,168,047. Analogue/digital converters. SINGER-GENERAL PRECISION Inc. 18 June, 1968, No. 29026/68. Heading G4H. An analogue input signal E (Fig. 3) is fed to analogue-todigital converter 43 which delivers a coarse digital value, this digital signal being converted to analogue form Eb and the difference of the two signals E - Eb after amplification being fed to the same analogue-to-digital converter 43 to form a fine digital signal. In the embodiment described when a reference ramp signal on conductor 67 crosses zero a flip-flop 75 is set to enable a gate 81 to pass clock pulses to a counter 47 and to close a switch 77 so that the analogue signal E and the ramp signal are compared, a comparator amplifier 69 resetting flip-flop 75 to terminate the count of clock pulses when the signals are equal. The count in counter 47 is then transferred to a six-stage register 49 controlling switches 87 in a digital/analogue converter 50 so that the analogue signal Eb is fed to amplifier 89. Amplifier 89 forms the difference signal and amplifies it by a factor of 2<SP>5</SP>, the amplified signal after inversion being fed via switch 79, closed when the flip-flop 75 is set by the reference ramp signal crossing zero, to the analogue/digital converter 43 for conversion to a fine digital signal. Logic 105 compares the most significant bit of counter 47 with the least significant bit of counter 49 so that an eleven-bit binary number is generated from the two six-bit coarse and fine signals. Further finer digital signals may be obtained by repeating the process. Small input signals are detected by a threshold detector 111, an analogue signal equivalent to the most significant bit of counter 47 then being added in to the input signal, this bit being subtracted from the digitized signal.
