Title: Improvements in or relating to weighing scales
IPC: G01G23/18
Filed: 1932-07-15
Abstract: 386,570. Weighing-apparatus. DAYTON SCALE CO., 468, Huffman Avenue, Dayton, Ohio, U.S.A. -(Assignees of Bryce, J. W., 160, Willard Avenue, Bloomfield, Ohio, U.S.A.) July 15, 1932, No. 20088. Convention date, Aug. 7, 1931. [Class 143.] Printed and perforated records, apparatus for giving ; loose-weight apparatus.-A weighing scale with a load support and a main automatic counterbalancing scale connected to the load support, and a settable loadoffsetting mechanism is characterized by the provision of a supplementary controlling scale with connections to the load support related and arranged to cause the supplementary scale to detect differences between the applied load and the load offset by the settable mechanism. The load on the usual weighing platform, operating through a draw rod 10 and levers 11, 18 is counterbalanced by pendulum mechanism 21 and indicated by a pointer 25. The operator then rotates cam shafts 67 by means of hand knobs so as to lower appropriate combinations of weights 53, 55, 57 (representing respectively units, tens and hundreds) on to a lever 51 connected by a lever 49 to the lever 11. The weights thus lowered are indicated by pointers associated with the hand knobs, and the operator sets the pointers to indicate the same weight as the pointer 25, the completion of the setting causing the pointer 25 to return to zero. If the setting is accurately performed, a printing handle 94 may be depressed, and a spring- actuated hammer 87 caused to take an impression on a record sheet 88 from type wheels 84 set by means of racks 81 geared to the cam shafts 67. If the setting has not been accurately performed, the taking of a record is prevented by an armature 99 which is moved to obstruct the printing handle by the energization of a magnet 42, the magnet being energized by the supplementary controlling device comprising a mercury switch 39 carried by a pendulum 34 coupled to the lever 18. A lamp shunted across the magnet 42 informs the operator that the lock is in operation and that the setting is inaccurate. In a modification, Fig. 6, the movement of the printing handle is used to actuate a perforated die 110 so as to press the record sheet 109 against a bank of spring-pressed punch pins 107 behind which interposer lugs 106 are set by racks 105 geared to the type-wheels 84. The presence of the interposer lugs prevents the selected punch pins from being pushed back by the record sheet and causes these punch pins to punch the sheet according to the Hollerith system. Specification 281,220, [Class 143, Weighing- apparatus], is referred to.

IPC: B41N1/08
Filed: 1920-07-09
Abstract: 148,325. Focke, P. April 9, 1918, (Convention date]. Drawings to Specification. Printing-surfaces; printing-processes; offsetprinting.-For reproducing a number of copies of typescripts, manuscripts, or drawings, the designs &c. are drawn on thin flexible zinc plates free from lead, or on sheets of metallized paper, by hand in lithographic ink, or are printed in a typewriter with an ink-ribbon inked by transfer ink. The metallized sheets are obtained by pasting thin sheets of zinc foil to paper, or coating paper electrolytically with metal, preferably zinc, and also with varnish or lac to protect the paper during the printing process. After the designs are produced on the metal surfaces, these are dusted with talc, etched with phosphoric acid and gum arabic, dried, washed, and rolled up with Indian ink. The metal plates are then mounted on printing-rollers fitted with inking and damping-rollers, and the designs are transferred to an offset roller which coacts also with an impression roller to which the paper sheets are fed from an inclined feed-board. The offset cylinder is of the same size as the printing-cylinder, but the printing-plates occupy only a half of the circumference of the printing- cylinders.

Title: An improved process for producing structures from cellulose esters of aliphatic acids
IPC: D01F2/28
Filed: 1930-07-04
Abstract: For the production of threads, films, tubes, hollow bodies, &c., from cellulose acetates and other cellulose esters of aliphatic acids, there are employed solutions of the cellulose esters in organic acids, and coagulation baths consisting of strong solutions of strong acids.  In examples, filaments are obtained by extruding solutions in acetic acid of secondary or primary cellulose acetates or a solution in formic acid of a cellulose acetate prepared without loss of the fibrous structure of the original cellulose, into 45 per cent sulphuric acid, and 45 per cent sulphuric acid containing an addition of sodium acetate, and 60 per cent sulphuric acid containing formaldehyde.  The strong acid produces swelling of the coagulated product, and it may also saponify the cellulose ester wholly or partly.  The products particularly if subjected to strong tension during production, are resistant to water, strong, ductile, and exhibit a low loss of strength on moistening with water.  To the coagulation baths may be added inorganic or organic salts, alcohols and aldehydes.  Reference has been directed by the Comptroller to Specifications 323,790, 324,662, 334,838, and 334,853, [all in Class 2 (ii), Cellulose &c.].

Title: Improvements in or relating to the destructive hydrogenation of carbonaceous materials
IPC: C10G1/00
Filed: 1933-07-19
Abstract: Solid carbonaceous materials and heavy non-volatile oils and tars are converted into light oils by subjecting the materials to a liquid phase destructive hydrogenation under such conditions that mainly volatile heavy oils (e.g. boiling between 300--500 DEG  C.) are produced, separating the heavy oils from the remaining products, destructively hydrogenating the heavy oils under such conditions that mainly middle oils are obtained, separating the middle oils and converting these in a further stage into petrols. The residual products containing solids are centrifuged imperfectly so that a residue rich in ash is obtained which is subjected to further destructive hydrogenation.  Hydrogen, coal, and <PICT:0425679/III/1> pasting oil are fed through lines 1, 2, 3 into a reaction vessel 4. The products pass to a hot catch pot 5 from which liquid heavy oil and residues are led off through pipes 13, 14 to the second stage reaction vessel 17.  The volatile oils and any lighter products pass through a condenser 7 and cold catch-pot 8 with reduction of pressure to a still 10 from which middle and light oil fractions are distilled off through pipes 11, 12 while the heavy oils are passed in part to the second stage reactor 17, the remainder being recycled as pasting oil to the reactor 4. Additional hydrogen is admitted to the reactor 17 through a pipe 18 and the hydrogenated products are passed to a hot catch pot 19 from which residual products pass through a pressure reducing system 20 to a sludge-recovery centrifuge 21 while the middle and light oils are condensed in a cooler 26 and then passed through a cold catch pot 27 and pressure reducing system 28 to a still 29 from which middle oils are separated by distillation and converted in a final stage into petrols.  Examples are given of the treatment of coal pastes, the reaction conditions in the first stage being 460 DEG  C., and 250 atmospheres pressure, and in the second stage 470 DEG  C., and 250 atmospheres.  Specifications 311,193, 336,610, [both in Class 32], and 359,108 are referred to.

Title: Improvements in automatic brakes for talking machines
IPC: G11B17/02
Filed: 1922-07-27
Abstract: 203,142. Gramophone Co., Ltd., and Buckle, H. L. T. July 27, 1922. Brakes. - A gramophone brake comprises a hand-operated lever which, when moved in one direction, pulls the brake-member proper into the inoperative position, when moved in the other direction puts the brake on by disengaging a latch, and when moved further in the latter direction sets a trip-lever into position for engagement by the tonearm, to effect automatic operation of the brake. A member 16 carrying the brake-pad 21 is mounted on a pivot 15 on which is also pivoted a member 23, connected at 26 to a slidable link 27. A latch 10 is connected by a spring 19 to a lug 17 on the member 16, and, when in engagement with a notch in the latter, holds the brake " off." The latch 10 is mounted on the same pivot 9 as a triplever 11, and is frictionally connected to this lever. An extension 13 of the member 11 projects into the path of a setting-lever 4, 8 which' coacts with lugs 30, 31 on the link 27 and with a lug 14 on the arm 13. When the setting-lever is moved by hand into the position shown, the arm 8 actuates the link 27 and thereby moves the member 23 round so that a finger 32 thereon pushes against the lug 17, turning the brakemember 16 into the " off " position, where it is held by the latch 10. The motor is then free to run. By moving the lever 4, 8 so that its outer end is at the position marked " stop " on a scale 6, the member 23 is reversed until a cam 24 thereon pushes the latch 10 aside and so frees the brake. Further movement of the arm 4 of the setting-lever towards the right causes the arm 8 to move the trip-lever 11 into such a position that, on subsequent running of the machine, a member 12 carried by the tone-arm engages the lever 11 at the end of the playing of a record. Such engagement shifts the latch 10 and allows the brake to act. A spring 34 normally holds the lever 4 in a neutral position, in which its pointer is between " start " and " stop." The Provisional Specification describes a modified construction in which the connecting link between the brake-member and the hand-operated lever is directly pivoted to the brake-member.
