Abstract: 185,033. McGaw, J. T., and Jenden, W. H. Sept. 23, 1921. Picture frames.-In an extensible picture frame of the kind in which the side members are formed of two portions disposed one in front of the other and are adapted to be fixed in adjusted position, one portion is provided with a bevel on its inner edge engaging a corresponding recess on the other portion, so that when the parts are assembled the back edges are coincident and form a continuous rabbet for the picture. Each side member of the frame preferably comprises two end portions A, A<1>, of equal length and mitred at the ends for attachment to corresponding portions of other side members, and a sliding portion B equal in length to the combined length of the end members and also mitred at the ends but unattached to other side members. The member B is bevelled at one or both edges B<1> and is accommodated in corresponding recesses in the end members. A guide D is held in a groove C in the recessed portion of each end member and retains the head of a bolt E in the end of the sliding-member B, a nut E<3> being provided for clamping the parts together. A small piece F is attached to the back of the member B to act as a stop for the glasses or picture. To aid further in keeping the members in alignment, a longitudinal projection may be formed on the member B to engage a corresponding recess in the end members. A thin slide, preferably of sheet metal, may be arranged between the sliding and end members to form an extra extension.

Title: Improvements in or relating to dictation installations
IPC: G11B25/00
Filed: 1960-07-20
Abstract: 899,193. Controlling magnetic recording &c. apparatus. SUD-ATLAS-WERKE G.m.b.H. July 20, 1960 [July 21, 1959], No. 25367/60. Class 40 (2). [Also in Group XXXIX] In a centralized dictation system (see Group XXXIX) a magnetic recording machine comprises a belt 59 passing over a driving roller 62 and an adjustable guide roller 61. Roller 62 and sound head M2 are driven by a motor 66 through friction wheels 67, 68, 69, of which wheel 68 may be lifted out of engagement by means of an electromagnet RM1. The sound head M2 may be stepped in the reverse direction by means of an electromagnet RM2, and depression of a button 81 against the action of a spring 80 permits manual movement of the sound head. To change the recording belt 59, an opening 60 is uncovered by movement of a lever 82 which also disengages the sound head M2 and an inclined friction roller 85 from the belt and opens contacts S3. Electromagnetically-operated means, Figs. 7 and 8 (not shown), for making index markings are mounted on a slide coupled to the sound head, and when the machine is released the position of the sound head at the end of the recording is automatically marked on the index strip. The sound head is automatically driven on to slightly beyond this position on release of the machine, even if it had previously been moved back for complete or partial repetition of the recorded dictation. This automatic resetting of the sound head occurs also after each repetition, whether the machine is released or not. Inadvertent erasure of a recording or its repetition to a subsequent dictator is thereby prevented, a stop being located behind the sound head on release of the machine.

Abstract: 267,177. Imray, O. Y., (Soc. of Chemical Industry in Basle). Oct. 12, 1925. 2-Methyl-3-chlorphenylthioglycollic acid; 6- chlor - 7 - methyloxythionaphthene; 6 - chlor-7- methylthionaphthenequinone and its anils; thioindigoid dyes.-6-Chlor-2-toluidine is diazotized and treated with alkali xanthate in alkaline solution, and the product saponified and condensed with chloracetic acid; the 2-methyl-3-chlorphenylthioglycollic acid so produced yields 6- chlor-7-methyloxythionaphthene by treatment with condensing agents. The oxythionaphthene yields, by reaction with an aromatic nitroso compound such as a p-nitrosodialkylarylamine or nitrosophenol, the anil of the corresponding thionaphthenequinone which can be saponified to the free quinone by treatment with sulphuric acid. By oxidizing the 6-chlor-7-methyloxythionaphthene or by condensing it or the corresponding thionaphthenequinone or its anils with the usual indigoid dye components vat dyestuffs are produced and may also be further halogenated. According to examples, (1) 2-methyl-3-chlorphenylthioglycollic acid is prepared and treated with phosphorus trichloride and aluminium chloride; the 6-chlor-7-metlyl-3-oxythionaphthene is then condensed with p-nitrosodimethylaniline and the 6-chlor-7-methylthionaphthenequinone-p-dimethylaminoanil produced saponified with sulphuric acid to obtain the thionaphthenequinone; (2) 6-chlor-7-methyl-3-oxythionaphthene is oxidized in alkaline solution to the 6 : 6<1>- dichlor-7: 7<1>-dimethylthioindigo which dyes cotton in carmine-red tints; (3) the oxythionaphthene is condensed with 5: 7-dibromisatin chloride, acenaphthenequinone or 5-chlor-7- methvl- or 6-chlor-4-methyl- or 6-ethoxy-thionaphthenequinone-p-dimethylaminoanil; (4) 6- chlor-7-methyl-thionaphthenequinone or its p-dimethylaminoanil is condensed with 5-chlor-7- methyl-3-oxythionaphthene: (5) 6-chlor-7-methyl- 3-oxythionaphthene is condensed with 2: 3-thionaphthisatin-p-dimethylaminoanil and the product brominated in nitrobenzene or chlorinated. A table is also given showing the dyeing properties of the dyestuffs from the 6-chlor-7-methyl-3- oxythionaphthene and 5-brom-2 : 1-thionaphthisatin, 1 : 2-thionaphthisatin, 1-chlor-2 : 3-thionaphthisatin, p-dimethylaminoanil of thionaphthenequinone or 6-chlor-thionaphthenequinone, a-isatin anilide, or 5 : 7-dibromisatin, The products dye cotton from the vat in orange, red, blue, violet, and brown shades.

Filed: 1924-10-25
Abstract: 249,899. Novocrete & Cement Products Co., Ltd., and Burney, C. D. Oct. 25, 1924. Plastic compositions containing fibres and cement &c.-Fibrous materials such as sawdust, shavings, coir, cork, wood waste, sizal, paper pulp, &c. are mixed, before and after moistening, with a dry hygroscopic substance which acts exothermally when brought into contact with moisture, and while heat is still being evolved the mixture is added to cement, concrete, &c. and cast in moulds. The dry hygroscopic substance may, for example, be dry caustic soda, quicklime, or magnesium chloride. The fibrous material may be subjected to a preliminary treatment to reduce its tendency to change in volume with change of moisture content, such as washing with a weak solution of alkali or acid. It may also undergo a preliminary impregnation with any suitable solution, followed if desired by treatment with a precipitating agent, or the dry hygroscopic substance may itself act as the precipitating agent. For example, sawdust may be impregnated with ferric chloride solution and then mixed with flaked caustic soda; cement and water are then added while heat is still being evolved, and the mixture is moulded under pressure as described in Specification 244,178. Specifications 236,450, 252,906, and 253,007 are referred to.

Abstract: 1,003,248. Adders. INTERNATIONAL BUSINESS MACHINES CORPORATION. June 24, 1964 [June 28, 1963], No. 26134/64. Drawings to Specification. Heading G4A. [Also in Division H3] An adding circuit for adding qui-binary coded decimal digits, comprises first and second sets of input lines providing first and second concurrent signals representing the digits, an adder matrix having solid state components and arranged for selectively coupling said first set of input lines with said second set of input lines, and having a set of sum output lines each including back circuit elimination means and a read-out latch controlled by the sum signals. In the particular embodiment, successive decimal orders are dealt with in turn as follows. Two binary-coded decimal digits to be added are stored in respective registers and their sign bits passed sequentially to a sign latch. The outputs of the registers and sign latch are supplied to AND and OR logic (Figs. 2a, 2d, 2g, not shown) to obtain the digits in qui-binary form when they are fed to resistor-capacitor adder matrices (Figs. 2b, 2e, not shown), one matrix for the quinary parts and one for the binary. The matrix outputs control read-out latches (Figs. 2c, 2f, not shown) via isolating diodes. Carries from the matrices are fed back and incorporated in the AND and OR logic, resulting in an adjustment of the matrix outputs, but a carry to the next decimal order is stored in a carry latch (Fig. 2d, not shown) for incorporation into the AND and OR logic with the next decimal order. The qui-binary output is converted back to binary (coded decimal).
