Title: Dual-purpose releaser for milking machine plants
IPC: A01J7/02
Filed: 1960-06-24
Abstract: 911,578. Milking machines. SEPARATOR A.B. June 24, 1960 [June 25, 1959; Dec. 9, 1959], No. 22177/60. Class 5(1). The releaser of a milking unit has its upper part 4 connected at 1 to the vacuum conduit 2 and its lower part 5 connected to vacuum through an electromagnetic valve 14 controlled by a relay 9. The part 5 is also connected to the relay by leads 8, 10 and 12. For cleaning purposes the port 5 is connected to vacuum and washing liquid is sucked from container 18 into the part 4 via pipe 16 and milk line 3 and passes into the part 5 through a flap valve 6. Liquid level in the part 5 rises until electrical connexion is made between the leads 8 and 12 to operate the relay to raise the valve piston thereby closing the vacuum pipe 15. Air then enters the part 5 through opening 17 and pipe 13 to allow the liquid to flow out through flap valve 7 into the container 18. When the level falls so that connection between leads 8 and 10 is broken the valve 14 is operated to close the opening 17 and connect the part 5 with vacuum and the cleaning cycle is repeated. During milking operation milk is fed from the part 5 into a can battery 21 through the pipe 20 or a valve 24 in the pipe 20 is closed so that the milk level rises to contact the lead 12, the relay operates valve 14 and milk is discharged through the valve 7. A switch 30 for short-circuiting the leads 8, 12 may be provided so that small quantities of milk are discharged through the valve 7.

Title: Recovery of silver from silver salts
IPC: C22B11/02
Filed: 1975-05-22
Abstract: 1454708 Production or recovery of silver GAF CORP 22 May 1975 [28 June 1974] 22283/75 Heading C7D Silver is produced from silver salts by heating in combination with an oxygen-containing alkali metal compound at 300-960C (M.Pt of Ag). Ag is formed in the unmolten state and is separated by heating the mass above the melting point for a short period. Suitable silver salts are the sulphide, sulphate, thiosulphate or, preferably, a halide; mixtures of these may be used. The alkali metal compound may be selected from the carbonates, hydroxides, nitrates, bicarbonates, sulphates, or mixtures of these, preferred compounds being the hydroxides, carbonates and nitrates of K and Na. The preferred starting material is photographic waste, e.g. film, processing solutions &c. When using waste film, the substrate material is removed by the action of proteolytic enzymes, or by heating in a strong acid or base. When using processing solutions, the Ag salts are recovered by evaporation. In examples chopped film is added to water and reacted with proteolytic enzymes, the Ag salts are separated as solids, and heated with soda ash (Na 2 CO 3 ) and NaOH (Example 1) with Na 2 CO 3  (Example 4), with Na 2 CO 3  and NaNO 3  (Examples 5 and 6); and AgBr is reacted with Na 2 CO 3  (Example 2) and NaOH (Example 3).

Title: Apparatus for controlling the operation of a plurality of talking machines in timed relation to a cinematographic machine
IPC: G03B31/00
Filed: 1920-03-10
Abstract: 169,134. Mosley, F. E. March 10, 1920. Rotary distributors.-Relates to apparatus for synchronizing a number of sound-reproducing machines with a kinematographic projector, in which the sound-reproducing machines are driven intermittently under control of means actuated automatically from a moving part of the kinematographic machine, so that each sound-reproducing machine is operated only when it is required to reproduce. According to the invention, the sound-reproducing machines are brought into and out of operation, in predetermined alternation or sequence, by means driven from the kinematographic machine but independent of the film. In the form shown, a shaft 15, Fig. 2, driven from the film-feeding spindle of a kinematographic projector, drives through bevel and worm gearing a shaft 3 carrying a detachable commutator drum 1, which may be secured on the shaft in one angular position only. The commutator comprises metallic rings equal in number to the gramophones to be controlled, fixed on the drum 1 and insulated from one another, each ring having on its periphery a number of conducting portions 31 separated by portions of insulation 32. The rings are electrically connected to terminals 36 on a plain conducting ring 33 mounted between insulating rings on the shaft 3. Spring-controlled brushes 43 press against the rings 31 and a spring-controlled brush 49 presses against the ring 33. The brushes 43 are separately connected to one pole of a battery, the other pole of which is connected to the brush 49. The gramophones are driven from a common shaft 56, Fig. 5, rotated by gearing from a continuously running pulley 59. In the drive of each machine is a pinion 63 feathered on its shaft 62, and displaceable therealong by a spring-controlled lever 69 actuated by the armature 71 of an electromagnet 72, the coils of which are included in the circuit of the corresponding commutator ring 31. As the commutator is driven from the kinematographic machine, the various electromagnets are intermittently energized, and the corresponding drive pinions 63 are thrown intermittently into and out of gear, thereby causing intermittent operation of the various record turntables 67. Each turntable is arrested always in the same position, as described in Specification 168,831, [Class 40 (ii), Phonographs &c.], by a catch 75 on the turntable adapted to engage a detent 76 operated by the lever 69.

IPC: C08B5/04
Filed: 1969-05-02
Abstract: 1,214,776. Nitrocellulose granules. DYNAMIT NOBEL A.G. 2 May, 1969 [4 May, 1968], No. 22628/69. Headings C3A and C3F. Nitrocellulose granules, generally having a bulk density of 0À4 to 0À6 g./cc., are prepared by adding a first quantity of a protective colloid and a water-soluble alkali metal or alkaline earth metal salt to a nitrocellulose lacquer, which has been produced by stirring nitrocellulose at a first speed in the presence of water and a solvent for nitrocellulose immiscible with water, stirring the mixture so produced at a speed of up to 60% of the first speed until the nitrocellulose lacquer forms into globules, allowing the globules to coalesce, adding a second quantity of a protective colloid and a water-soluble alkali metal or alkaline earth metal salt, increasing the stirring speed to from 60 to 95% of the first speed, allowing the lacquer to separate into globules, distilling off the solvent and collecting the nitrocellulose granules obtained. Preferably, the nitrocellulose lacquer has been produced by stirring at a first speed of 50 to 90 r.p.m. at 50 to 90 C. The nitrocellulose lacquer may contain a stabilizer such as a phthalate, urethane, methyl and/or ethyl diphenyl urea, diphenylamine or petroleum jelly. The protective colloid may be bone glue, gelatine, gum arabic or gum shiraz and the nitrocellulose solvent may be a waterinsoluble methyl, ethyl or butyl ester of a saturated C 1-5  aliphatic carboxylic acid. The salt may be any alkali metal or alkaline earth metal sulphate, chloride or nitrate, e.g. anhydrous sodium sulphate, and may be added in the form of a saturated aqueous solution. The nitrocellulose granules may be dried at 60 to 85 C. in a current of warm air. The bulk density of the nitrocellulose granules may be further reduced by a " density-lowering process," preferably carried out by treatment of the granules with water and a solution of glycerine trinitrate and/or ethylene glycol dinitrate in ethyl acetate.

Filed: 1939-08-09
Abstract: 545,182. Automatic exchange systems. STANDARD 'TELEPHONES & CABLES, Ltd., and WRIGHT, E. P. G. Aug. 9, 1939, No. 22978. [Class 40 (iv] In a single-motion group selector which acts. in combination with an associated impulse regenerator to select an idle junction of a group determined by the first digit received, all the digits including the first being then retransmitted over the junction, the regenerator is of the condenser-storage type having a receiving switch SS and a follow-up sending switch SR, and in response to the ,first digit the receiving switch marks the group to be searched by the selector DS. The arrangement enables several exchanges of a capacity of 1000-4000 lines to be reached over a single level of a preceding group selector. Upon seizure, line relay A energizes followed by B, MD, J and the switch SR is stepped by the incoming digits. Relay M energizes over a marking applied to the first contact of each group and allows the selector DS to chase SR until the first outlet of the wanted group is reached. Relay E pulls up on the relapse of dialling relay C and disconnects M, whereupon DS hunts over the group. When an idle junction is found, FT energizes and connects up switching relay SH, which operates SD to start retransmission. Impulses are sent over the junction and to the sending switch SS by vibrating relay VB, and each digit is ended when relays S, Z are operated by condenser discharge. The successive relapse of Z, ZZ measures the inter-digital pause. Relay Z holds when all the digits have been sent. The first digit may be suppressed when it is not required. at the distant exchange by means of relay RA, which energizes in the relevant position of SR and shunts the loop impulse springs until the first operation of Z. If no idle junction is found, relay M reoperates over the last contact of the group and connects up busy relay OB.
