[Class 1 (iii)] In a cyclic process for the manufacture of copper acetoarsenite, a solution containing copper aminoacetate reacts with solid arsenious acid in such quantity that no free acid is formed. After separation of the precipitate, acetic acid is added to the mother liquor which is recirculated to a tower or similar apparatus containing copper to form further copper aminoacetate for a reception of the process. The process is preferably carried out with an excess of copper salt, say with 5 mol. of copper salt to 3 mol. of arsenious acid, the excess of copper salt over the stoichiometric proportion of ' copper aminoacetate being either copper aminoacetate or copper acetate. Losses of ammonia are thereby prevented. The Specification as open to inspection under Sect. 91 comprises also a non-cyclic process. This subject-matter does not appear in the Specification as accepted.

Title: Process for the production of dihalocarbene derivatives
IPC: C07C23/28
Filed: 1963-05-13
Abstract: Dihalocarbene derivatives are produced by reacting an initially substantially anhydrous mixture of an alkali metal hydroxide and a haloform with a dihalocarbene acceptor, the haloform containing at least one chlorine or bromine atom.  The effect of the water generated by the reaction is minimized by using an excess of alkali metal hydroxide over the haloform. The reaction may be in an ether solvent or a cyclo-paraffin sulphone solvent and the metal hydroxide is in the finely divided state. Numerous examples of haloforms and acceptor substances are given and specific examples describe the preparation of the following compounds:-dichloronorcarane, 9,9-dichlorobicyclo - (6,1,0) - nonane; 2 - oxy - 7,7 - dichloronorcarane; 1,1 - dichloro - 2,2,3,3 - tetramethyl cyclopropane; 6,6 - dichloro - 3 - oxabicyclo - (3,1,0) - hexane; p - methoxyphenylisonitrile; 1,1-dichloro-2-cyanocyclopropane; diphenylcyclopropenone; 2,2 - dichloro - 1,3 - diphenylethyleneimine; 7 - chloro - 2,3 - benztropone and methyl chloride; methyl-2,2-dichlorocyclopropyl carbinol.

Title: Improvements in telegraph systems
IPC: H04L9/18
Filed: 1937-07-09
Abstract: 547,593. Type-printing telegraphy. CREED & CO., Ltd., and THOMPSON, A. E. July 1, 1937, No. 19137. [Class 40 (iii)] In a step-by-step field telegraph, impulses are sent to line at an even rate and signalling is effected by repeated reversals of polarity in order that, in the interests of secrecy, the impulses may be prevented from causing clicks in a telephone receiver coupled to the line. A continuously driven shaft a causes a contact r2 to be reciprocated by a cam s so that impulses are sent to the line r at an even rate, the line being disconnected in the intervals between the impulses. The polarity of the impulses is determined by a contact n2 whose position is set by a cam n on an intermittently rotating shaft b which is driven by the shaft a through a clutch c. The clutch is controlled by linkwork, part of which is carried by an arm h rotating above a disc i having letter keys such as k arranged around its periphery. When the transmitter is idle, the arm h is held by the key last operated, and signals of uniform polarity are sent to line ; but when a fresh key is depressed the arm is released and rotates until that key is released. The clutch c, released so long as the arm h is rotating, causes successive impulses to be of opposite polarity during the signalling of the letter. Instead of intermittently disconnecting the line, the contact r2 may intermittently earth it, Fig. 3 (not shown).

Abstract: 856,783. Straightening. PLESSEY CO. Ltd. June 16, 1959 [June 17, 1958], No. 19310/58. Class 83 (4). A method of straightening the wire ends of a wire-ended electrical component comprises applying a set of jaws of relatively short axial length to each wire near the component and then applying radial pressure to the jaws and causing the set of jaws to move away from the body, or vice versa, while maintaining relative rotation between the component and set of jaws about the axis of the wire ends. The body of a wire-ended component 1 is held firmly on a recessed anvil 4 by a pad 8 pressed down by a pneumatically-operated ram 6. While the body is thus held, jaws 14, 15, on arms 10, 11 pivoted at 12, 13 to a head 9 held in a chuck 16 of a power tool 17, e.g. a pneumatic hand drill, are applied to a wire end 2 near the body of the component 1. The jaws 14, 15 are rotated about the wire axis by the tool 17, weights 20, 21 on extensions of the arms 10, 11 causing, by centrifugal action, the jaws to press on the wire, while at the same time the jaws 14, 15 are moved axially along the wire towards its free end by moving the tool 17 axially, either manually or by a pneumatic cylinder 19. A tool and jaws may be provided for each of the two wires. Three or more jaws may be provided on each head and spring or pneumatic means may close the jaws on to the wire.

Title: Animated doll or display device
IPC: A63H3/48
Filed: 1966-05-03
Abstract: A doll has electrically-operated eyes and sound-producing means.  The eye-ball is divided into sections, two simulating an open eye and a closed eye respectively and a third being highly polished for image reflection, and has a weighted extension positioned so that movement of the extension under gravity opens the eye when the doll is upright, and closes it when the doll is horizontal.  Further rotation of the eyeball of the horizontal doll, to display the reflecting part, is by electromagnetic means. Placing the doll in a horizontal position closes a position-operated switch (which may be of mercury), which energises electromagnetic means, causing its core to engage with the eyeball extension and rotate the eyeball.  Simultaneously, electrically-operated sound-reproducing means are operated by a hand-operated electric switch, while the body is in any position. The sound reproducing means possess further means to de-energise the electromagnetic means, so that when the sound stops, the electromagnetic means is de-energised and the eyeball returns to its non-reflecting closed position.  Means may be included to regulate the dimensions, especially the length, of the body, in relation to the quality or timbre of sound emanating from the sound reproducing means, by making the body hollow and of elastic material and containing at least one compartment defined by a partition wall, and by providing the body with means for regulating admission and escape of a fluid to and from the compartment.  The partition wall may be used to strengthen the doll's body, and to support the sound-reproducing means.  The doll may be used to send a child to sleep, by means of the sounds from the sound-reproducing device and reflection of the child's image.
