Abstract: 389,554. Packing fragile articles. POLLAK, J. E., 20, Holborn, London.- (Merck, E., [Firm of]; 250, Frankfurterstrasse, Darmstadt, Germany.) Oct. 26, 1931, No. 29637. [Classes 94 (i) and 125 (i).] In order to protect bottles, glass bulbs, and like articles from breakage, they are individually enveloped by a winding of wood-wool, hay, straw, &c. before packing in a crate. The bottle a is held between a rotatable cushion plate m and a spring bearing o adapted to be withdrawn by a pedal q. A member e, preferably made in hinged sections, and mounted on a longitudinally slidable carrier t, surrounds the bottle, and is slotted to allow insertion of the wood-wool &c. while the bottle is rotating. Spikes d on the plate m serve to centre the bottle and also to carry round the wood-wool to cause it to surround the bottle. The member e may be heated by steam or hot water, and a binding material such as glue or paraffin may be introduced to unite the fibres of the sheath. The member e is opened and the bottle and sheath removed from the plate m and spikes d axially. In a modified arrangement, the bottle may be mounted for rotation about a vertical axis.

IPC: H04N1/40
Filed: 1967-06-27
Abstract: 1,170,629. Image reproduction; transistor amplifying circuits. CROSFIELD ELECTRONICS Ltd. 22 July, 1968 [27 June, 1967], No. 29646/67. Headings H4F and H3T. The response of a glow modulator lamp in an image reproducing apparatus is improved by including in the driving amplifier for the lamp a D.C. feedback network which includes a circuit having a characteristic which is the analogue of the dynamic behaviour of the lamp. In the D.C. feedback network shown in Fig. 2 a field-effect transistor 42 serves as a multiplier of a signal derived through a potentiometer R1, R2 from the emitter of a transistor 38, Fig. 1, and a signal from the same source which has passed through an R.C. network R3, R4, C. The R.C. network introduces a time-lag corresponding to that displayed by the lamp in response to transient signals, and the output from the fieldeffect transistor 42 is fed back to the input of an amplifier 36 which supplies the transistor 38. The glow modulator lamp is supplied from the collector of the transistor 38. Other forms of multiplier may replace the field-effect transistor 42. In the embodiment the reproducing apparatus comprises synchronous analysing and exposing scanners including drums 2, 4 rotating on a shaft 6. A transparency to be reproduced is placed on the drum 2 and scanned by an analysing head 16 using light from a source 12 reflected by a mirror 10 linked to the head 16. For colour reproduction the head 16 includes a colour separator and three photo-multipliers, each responding to one of the selected primary colours. After colour and tone correction at 32 one of the component colour signals is selected at 34 and applied to the glow modulator lamp in an exposing head 23 via the amplifier 36, transistor 38 and feedback network 40. The sensitive sheet to be exposed is situated on the drum 4 and scanned by the head 23. Three separate exposing scanners may be provided to simultaneously reproduce the three colour component images on separate sheets.

Title: Improvements in the manufacture and production of shaped articles from polymerised vinyl carbazole
IPC: B29C67/00
Filed: 1935-10-29
Abstract: Articles are produced from polymerized vinyl carbazole or mixtures thereof by subjecting the material to a treatment by which the molecules are orientated in a definite direction, comminuting the resulting material and pressing it at a temperature at which no complete fusion takes place.  The mixtures may comprise vinyl carbazole and styrene, butadiene, or vinyl ethers.  In order to produce the desired orientation the material may be extruded at temperatures above 200 DEG  C. in the form of bands, foils, rods, or tubes, or rolled between hot rollers and subjected to a tensile stress by a second pair of rollers running at a higher speed but at a lower temperature, or formed into thin plates or rods in an injection moulding machine at temperatures above 200 DEG  C. the receiving mould being at a temperature between 50 and 200 DEG  C.  The substances thus produced are comminuted in cross-beater mills, crushers, &c., and the resultant fibrous mass is moulded at temperatures from 180 to 250 DEG  C.  Softening agents and fillers may be added or insertions of fabric, metal wires, mica leaves or asbestos masses.  The fibrous mass may be tableted and preheated to about 225 DEG  C. before the final moulding. According to the Provisional Specification the preliminarily formed sheets, instead of being comminuted, may be laid on one another with their molecules orientated in different directions and pressed at temperatures from 200 to 250 DEG  C.

Title: Improvements in door stops
IPC: E05C17/20
Filed: 1932-10-25
Abstract: 410,812. Checking-devices for doors. SMITH, J. T., and SILENT TRAVEL, Ltd., 28, Albemarle Street, London. Oct. 25, 1932, No. 29843. [Class 65 (i).] A device for cushioning and checking the opening movement of a vehicle door comprises two stop members, mounted on the door and the hinge post respectively, with cushioning means stressed by the engagement of the two stop members so as to check the door movement, one of the stop members consisting of a link or arm extending through the hinge post or the door framing and the other comprising a detent or lever mounted to rock on a rubber sleeve or like flexible bearing forming the cushioning means, the arm having a link to engage the detent to produce torsional stress in the rubber. The arm may be pivoted to a member mounted for limited axial displacement in a rubber sleeve or like flexible mounting. The detent may engage a rigid abutment near the fully-open position, so that the mounting of this member does not yield any further and greater resistance is opposed to the movement of the door. In the form shown, the Figure being a partial section in the plane of the door, the two stop members are constituted by a bracket l mounted on a silentbloc bearing m on the door member h and an arm b pivoted to the head d of a stem g mounted in a silentbloc bearing f recessed in the door-post a, to which the door is hinged at n ; the arm b is bent in a horizontal plane so as to lie always inside the door, and is guided by an aperture with rounded edges formed in a plate j held beneath the plate k which supports the bearing m of the bracket inside the door. As the door is opened, a beak b<1> on the arm b engages a lateral portion of the bracket l, and further movement of the door causes rotation of the bracket l against the resistance of its bearing m and axial displacement of the stem g in its mounting, which also resists the motion. When the door is nearly fully open, the bracket l comes into contact with the plate k, as shown dotted, and is thus prevented from yielding further, movement of the door being then permitted only by axial yielding of the mounting f which imposes increased resistance. In a modification, the arm b may be mounted on the door and the detent bracket l fitted inside or behind the door post.

Title: Manufacture of dichlorovinyl ethers
Filed: 1946-10-09
Abstract: Dichlorovinyl ethers are obtained by heating a compound of the general formula R-O-A, in which R is an aromatic residue and A an alkali metal, with trichloroethylene in the presence of water and/or organic solvent containing a hydroxyl group.  The products probably have the formula R-O-C(X)= C(X).Cl in which R is an aromatic residue, and one X is a hydrogen atom and the other X a chlorine atom. Specified organic solvents are an aliphatic alcohol, e.g. ethyl alcohol, isopropyl alcohol or tertiary amyl alcohol, and phenols.  It is preferable to effect the reaction under pressure at a raised temperature.  In examples: (1) phenol is dissolved in a solution of sodium in absolute alcohol, trichloroethylene is added and the mixture heated in a closed vessel, the reaction solution is taken up in water and ether, the ether layer washed with caustic soda solution and water and then dried, the ether distilled off and the residue fractionally distilled to yield dichlorovinyl phenyl ether; (2) para-chlorophenol is used, the reaction being effected as in (1), isopropyl alcohol, tertiary amyl alcohol or para-chlorophenol may be used instead of absolute alcohol but in any of these cases the sodium salt of the para-chlorophenol used is first prepared as in (1), isolated from the absolute alcohol and then dissolved in the chosen solvent, the reaction then being effected at higher temperature than in the case of absolute alcohol; (3) paraoxydiphenyl is used as in (1) but the reaction is effected by prolonged boiling of the mixture under reflux; (4) and (5) trichloroethylene is added to a solution of sodium hydroxide and para-chlorophenol in aqueous alcohol and in water respectively the mixture in each case being then heated in a closed vessel and worked up as in (1); (6) a solution of sodium phenolate in water and trichloroethylene is heated in a closed vessel; in other examples the following phenols are used and the reaction effected as in (1) : 2 : 4 - dichlorophenol, 2 : 5-dichlorophenol, 2 : 4 : 5-trichlorophenol, tetrachlorophenol, pentachlorophenol, ortho-cyclohexylpara-chlorophenol, 2 - oxy - 5 : 41 - dichlorodiphenylmethane, 4 : 41 - dioxydiphenyldimethyl - methane, 41 : 411 - dichloro - 4-oxy-triphenyl methane, 4-oxytriphenyl methane, para-nitrophenol, b -naphthol, 1 : 4-chloronaphthol, 4-chloro-2-amino phenol, and ortho-oxyacetophenone. It is stated that the potassium salts may also be used as starting materials and the products are stated to be high boiling liquids or solid crystalline compounds useful as intermediates in the dyestuff industry and stable to boiling water, boiling dilute aqueous alcoholic solutions of hydrochloric acid and dilute alcoholic solutions of caustic alkalis.

[Class 100 (ii).] Rotary machines ; tripping-arrangements.- In a selvage-printing machine, for use in conjunction with fabric-treating machines, such as stentering-machines, and of the kind comprising rotating type-holders adapted to present the type to the selvage at regular intervals, and a presser member adapted to press the selvage against the type when presented or to be held clear of the type, cam or like means is provided for raising the presser member and fabric clear of the rotating type and is such that the interval at which marking is effected may be varied. The printing-machine may be arranged at the delivery end of the stentering &c. machine or at the entrance ; in the latter case, the cloth is guided by hand or by a feeding device to ensure the selvage being kept in a true path. As shown, a fabric is passed between a rotatable drum c and an impression roller s with the selvage passing over a stud p, under an impression roller n, and over a stud q, the fabric being fed by the stentering- machine and serving to rotate the drum c, which is coaxial with and rotates a boss d with radial arms d<1>, d<2> carrying types for printing trade marks &c. The stud p projects from a pivoted arm o supporting the roller n also, and the arm is adapted to be rocked to lift the roller and the fabric out of coaction with the types by means of a tappet rod m actuated by an eccentric pin l carried by a shaft k<1> rotated by a chain f<1> passing over a sprocket f driven from the drum c. When two impressions are required for each rotation of the drum, the rod m is lifted off the pin l and reversed so as to clear the arm o ; when one impression is required, one type is removed, and when the impression is required every other revolution, the rod is put into use in addition. The eccentric may be geared up, further to extend the intervals. The printing-machine may be mounted on rails or screws for transverse movement across the fabric, and two machines may be mounted on one frame, one for each selvage. Holders for loose types.-The types are secured to the arms d<1>, d<2> by means of clamps j. Inking-apparatus.-Ink is applied to the types by a roller g<3> resting on a duct-roller g rotated by a chain e<1> driven by the drum c. Rollers g<2> spring-pressed against the roller g remove superfluous ink and distribute the ink.
