Title: An improved process and apparatus for the destruction of algae and fungi in water or sewage
IPC: C02F1/76
Filed: 1929-09-20
Abstract: 340,218. Mixing fluids in flow. ORNSTEIN, G., 48, Alexandrinenstrasse, Berlin. Sept. 20, 1929, No. 28586. [A Specification was laid open to inspection under Sect. 91 of the Acts, Dec. 16, 1929]. [Class 86.] A process for the destruction of algµ and fungi in water or sewage consists in the addition of both chlorine and copper salt solution thereto. Chlorine may be added as a gas, in solution, or in the form of hypochlorous acid or hypochlorite solution. An apparatus for simultaneously regulating the quantities of solutions of both the reagents added to the liquid to be treated comprises a water supply pipe L leading to a vessel M containing a siphon having a two-branched discharge pipe leading to vessels N, N<1>. The discharge pipes of the vessels N, N<1> have injectors O, O<1>, the aspirating tubes of which are connected to siphons P, P<1> supplied from storage vessels P<2>, P<3>. Supply bottles R, R<1> maintain a definite liquid level in the vessels P<2>, P<3>. According to the rate of flow of the water in the pipe L the vessel M discharges with varying frequency, and the outflowing water causes a suction in the pipes O<2>, O<3> connected to the siphons P, Pl. The siphons P, P<1> draw from the storage vessels P<2>, P<3> definite quantities of the respective solutions and pass them to vessels S, S<1> having a liquid seal and thence to the water to be treated. Other dosing devices may be used, e.g. an apparatus similar to that described in Specification 300,898, or a bucket wheel on the driving shaft of which two other bucket wheels are mounted which are supplied with solutions of the two reagents respectively. Reference has been directed by the Comptroller to Specifications 81/02, 22351/11 and 300,898, [all in Class 46, Filtering &c.].

Abstract: 603,797. Yarns. CLARK, D. M. (Abbott Machine Co.). Oct. 30, 1945, No. 28717. [Class 120(iii)] [Also in Group XVII] Yarns are formed into a package for transport or subsequent processing by running them on to the surface of a growing mass of yarn on which a gaseous pressure is maintained. The yarn Y, taken from a cake or similar package, is delivered by rollers 11 to a container 13 having a perforated base through which air is drawn by a fan 17 in a stationary housing 15 on which the container 13 is placed. It is stated that the suction developed causes a compact package of even density and thickness to be formed. When the container is full and while suction is still applied a lid may be fitted which has a central hole for use if the yarn is to be drawn off for mechanical processing, such as warping or knitting or if the package is to be carried by a loom shuttle. If the yarn is to be liquid-processed, such as by dyeing or sizing, a perforated lid may be fitted and the entire container applied to a dyeing or like machine wherein liquid may be passed through the package. The twist, of the yarn_ may be set by such liquid treatment and the yarn may also be dried in the container, which may be made of metal or of paper, cardboard or other fibrous material treated, if desired, to render it resistant to yarn processing liquids.

Title: Pump with variable output and constant number of strokes
IPC: F04B49/10
Filed: 1920-10-14
Abstract: 152,363. Silvestri, G., and Findenigg, A. April 18, 1914, [Convention date]. Pumps with means for reversing direction of flow; single-acting pumps with multiple-suction and multiple -delivery; regulating delivery by closing and opening suction and delivery valves.- A pump with variable output and constant number of strokes comprises a barrel a connected by a pipe f to a casing g containing a rotary valve h driven from the pump shaft e. The valve has one or more chambers i, open to the suction pipe m and one or more chambers k open to the delivery pipe n and is rotatably adjustable so as to vary its phase relatively to the stroke of the pump piston b. In the position shown in Fig. 1, the chamber i opens to the pipe f at the beginning of the suction stroke and the chamber k at the beginning of the delivery stroke, and the output is a maximum. If the valve is adjusted so that the chamber k registers with the pipe f before the end of the suction stroke, the pump draws liquid from the delivery pipe during the latter part of the suction stroke, and during the latter part of the delivery stroke liquid is delivered to the suction pipe through the chamber i. When the lead of the valve on the pump piston is 90 degrees the output is nil, and when the lead exceeds 90 degrees the direction of the flow is reversed. To prevent excessive vacuum and pressure in the barrel a during the short time when both chambers i, k are closed to the pipe f, secondary suction and delivery pipes p, s, with valves o, r, are provided between the barrel and the main pipes m, n. The valve h is adjusted by moving the rolls carrying the driving chain in the direction of the arrow.

Title: Timing device
Inventor: LUCKETT CHRISTOPHER HAWTHORN
IPC: B65G47/48
Filed: 1964-07-15
Abstract: 1,094,852. Endless conveyers. NEW CONVEYOR CO. Ltd. July 15, 1965 [July 15, 1964], No. 29166/64. Heading B8A. [Also in Division H2] In sorting packages they are carried on the upper inclined run 11 of an endless belt conveyer and discharged at one of a series of stations selected on a keyboard 41. At each station, a gap in a sidewall 12 of the conveyer is normally closed by a trap door 13 which is operable by an hydraulic unit (14) (Fig. 3, not shown). The supply to the latter is controlled by a solenoid valve (not shown) energized by the closing of all three micro-switches (50), (51), (52) (Figs. 7 and 8, not shown) at a reading head (48) (Fig. 4, not shown) corresponding to the discharge station under consideration. The reading head (48) and reading heads (43), (44), (45) and (49), corresponding to the discharge stations, are spaced around the periphery of a wheel 21 which rotates in synchronism with the conveyer belt. The wheel 21 carries peripherally disposed series of groups of three coding pins 28. These are normally all disposed in a leftwards position (as in the case of the top and bottom of the three pins 28 shown in Fig. 7). When, however, the destination of a package, arriving at the conveyer belt, is keyed at 41 a corresponding group of pins 28 is set to a code according to the desired delivery station. The code is based on the possible arrangements of the three pins 28 in retracted or rightwardly (as viewed in Fig. 7) extended positions. Each extended pin engages an operating feeler (53), (54), (55) of the corresponding one of the respective micro-switches (50), (51), (52), to cause the respective switch to be moved to closed position. At each discharge station, switches (50), (51), (52) are arranged normally open or normally closed in a binary code corresponding to the setting of the pins 28 for discharge to occur at the respective station of the elements 28. Thus for discharge of a package at the station corresponding to the reading head (48), the pins are set according to a binary digit group 101 and the normal setting of the switches is open for switches (52) and (50) (corresponding to the top and bottom pins 28), and closed for the switch (51). The operating feeler of every normally closed switch (e.g. switch (51)) is extended in a peripheral direction opposite to the direction of the rotation of the wheel 21. This has the effect of the closing of any trap door opened for the discharge of a previously discharged load by pins 28 set to a code which differs from that designated for the particular station. The mechanism for setting the pins 28 comprises a setting device (Fig. 5, not shown) having solenoid-operated setting members (31), (32), (33). This device cannot operate in response to the keying of a code until the load has passed a photo-cell (42).

Class 98(2) Hardened gelatin relief matrices which absorb dye in excess of the amount necessary to correctly reproduce the colour aspect of a scene are treated with a proteolytic enzyme bath for a predetermined time sufficient to solubilize a portion of the gelatin, and then as with a warm water bath to dissolve the gelatin portion, thereby reducing the dye absorption without destroying the contrast. An enzyme bath standardized in activity and temperature may be used and the time of immersion of the relief matrices therein correlated with the time of treatment in a washback apparatus as of Specification 671,564 as used normally to reduce the dye in matrices made originally to absorb excess of dye. Matrices initially satisfactory but which become too absorbent on repeated use may be treated similarly instead of being discarded. Trypsin and various proprietary enzymes are quoted for the purpose and operation proceeds independently of the presence of absence of silver in the matrix. Four examples and lists of yellow, magenta and cyan dyes are provided.
