Title: Improvements in and relating to motor or pedal cycle brake-operating mechanism
IPC: B62L3/02
Filed: 1935-03-15
Abstract: 447,441. Cycle brake-operating mechanism. BARROS, J., 66, Craven Park, Harlesden, London. March 15, 1935, Nos. 8077 and 25157. [Class 136 (i)] Mechanism for simultaneously operating the front and rear brakes of a pedal or motor cycle from a single actuating-device is so constructed that the force applied to the two brakes is equalized and the fracture of one brake wire does not incapacitate the remaining brake. In the form shown in Figs. 1-3, a bracket 1 clamped to the handle-bar 12 is pierced at 2 and slotted at 3 to receive two outer cable adaptors 2<a>, the inner wires being connected by means of nipple holes 15 to a U - shaped triangular rocker 5, which is pivoted at 14 to a pair of links 6 pivoted at 13 to a lever 9, which is pivoted to the bracket at 10. The ends of the pivot pin 14 are guided on flat edges 4 of the bracket 1, or by ribs or channels on the bracket. The edge of a washer 11 on the pivot 10 abuts against the handle-bar 12 to ensure rigidity of the bracket 1. By reason of the triangular shape of the rocker 5, fracture of one wire causes only a limited amount of slack in the other wire. In a modification, wire-nipple connectors are pivoted to the rocker, and the latter is pivoted directly to the lever 9. Other modifications of the rocker and its connections are described. In a further form, Fig. 13, the lever 9 is connected to the rocker 5 by a chain 27 passing around a pulley 28 and having its end connected at 26 to the bracket 1, whereby the mechanical advantage is increased. The heads 29 of the pulley spindle engage guide slots 30.

Title: Stored information retrieval system
Filed: 1959-03-09
Abstract: 909,353. Record card systems. TAUBE, M. March 9, 1959 [April 4, 1958], No. 8083/59. Class 106 (1). In a searching system a group of record cards is provided for each feature or heading under which the items may be classified, the cards of each group bearing the numbers of all the items having that feature and the numbers of items having two features are found by comparing numbers on the cards of the corresponding two groups and recording those numbers which appear in both. The items may be documents together forming a library collection and the features may consist of headings such as " radar " or " jamming." There may be about a million items, 10,000 features or headings and each item may be classified under 5 to 15 headings. Each card 10 bears at 12 a number defining the heading and at 14 37 item serial numbers in numerical order. These are recorded by combinational punchings in two columns (the serial numbers having up to six decimal digits). Each group will probably consist of about fifty cards. Cards from two appropriate groups A and B, Fig. 4, are fed one by one to sensing brushes. The cards move in steps through the sensing station, two columns of holes being sensed at once by two rows of brushes. The serial numbers read from the two cards are compared and the card feed mechanisms 34, 36 are controlled by the comparator 42 so that the card having the lower item number in the sensing position will be the next to advance. When the numbers in the sensing positions agree, the comparator causes this number to be punched into a result card 54 in a punch 48. The card 54 therefore bears the numbers of all items classified under headings A and B. By causing the punch to punch all item numbers sensed from the A cards and all those sensed from the B cards except when they are in agreement with the number sensed from an A card, all the items having features " A " or " B " are listed without duplications. Other arrangements are mentioned. Specifications 655,674, 683,857 and 721,828 are referred to.

Abstract: 291,717. Siemens Akt.-Ges., F., Durrer, R., Siemens, F. C., and Sprenger, A. Dec. 24. 1926. Divided on 293,326. Refining.-In making steel in a Siemens- Martin furnace, dust from coal poor in gas, coke, semi-coke, or poor coal, is introduced into the furnace at least from the termination of the refining stage in such a manner that it forms a protective layer over the bath. The coal dust may be introduced into the furnace mixed with combustion gas or may be blown into a stream of blast furnace gas by means of blast furnace; and the furnace may be fitted with a coal dust combustion chamber, or a coal dust combustion chamber mav be constructed as an auxiliarv combustion chamber to a blast furnace gas combustion chamber. The coal dust may be used along with gas from a tapping generator operated without steam and employing coke or semi-coke or like coal poor in gas. The excess heat of the Siemens-Martin furnace may be used for preheating the air of such a tapping generator. The coal dust may be blown in in such a manner that the protective layer is formed between the gas current and the bath, and in such a manner as to fill the corners with which the gas current does not come into complete contact. During the refining stage coal dust may be blown in along with air, and after the refining stage coal dust without air. In some cases coarse coal dust may be used along with fine coal dust.

Title: Improvements in or relating to forming or shaping presses
IPC: B27D1/08
Filed: 1938-03-23
Abstract: 506,780. Fluid -pressure presses. FRIZ, A. March 23, 1938, No. 8857. Convention date, Oct. 29, 1937. [Class 122 (iii)] [Also in Groups VIII, XVI, and XXIX] In presses for veneering, forming, or shaping of the type in which the work-piece placed on a table is subjected to pressure by a resilient sheet covering the lower side of a hood into which a pressure medium is introduced, and in which a plurality of connecting elements serve to prevent the hood receding from the table, there are further provided tightening elements which press the resilient cover on to the rim of the hood, and which become operative on all the connecting elements uniformly and simultaneously. A work-piece 7, Fig. 1, placed on a former or shaped strip 6 on the table 1 is covered by a rubber sheet 5, a hood 3 with a thickened rim 4 is placed on the rubber sheet, latches 8 pivotally connected to the hood engaging automatically with lugs 9 on the table, and the rubber sheet is pressed against the rim 4 of the hood by admitting pressure medium from a container 11 to a distensible rubber pipe 10 in a groove in the table, before admitting pressure medium to the hood. To obtain better sealing, a narrow strip 14, Fig. 3, e.g. of rubber may be combined with a flexible strip 13 disposed above the pipe. The latches 8 along each side may be secured on a single shaft, the four shafts being connected at the corners by bevel gears. In a second construction the latches are pivotally connected to the table and grip over an upwardly-directed rim on the hood, the margin of the resilient sheet being disposed between the hood rim and the latches so that when the hood rises on the admission of pressure medium, the latches press the resilient cover on to the rim. The rim-engaging portions of the latches may be replaced on each side of the hood by a single bar connecting the latches and engaging the rim along its whole length. In a third construction sealing is effected by pressing the hood down on to the rubber sheet on the table by the interaction of inclined cam surfaces on the lower ends of metal bands extending over the top of the hood, with wedge-shaped cam faces on a bar slidably mounted in a guide in each side of the table and actuated by a pneumatic cylinder. The pressing-down may be effected by lever-action instead of cams. The pressing-up of the rubber sheet against the lower surface of the hood as in Fig. 1, or the pressing-down of the sheet against an upwardly directed rim, may also be effected by cam or lever action.

Title: Improvements in and relating to the manufacture of sensitized photographic printing paper and cloths
IPC: G03C1/64
Filed: 1933-03-24
Abstract: 418,369. Photographic blue prints. HALDEN & CO., Ltd., J., and HOLDEN, J., Rowsley Works, Reddish, near Stockport, Cheshire. March 24, 1933, No. 8900. [Class 98 (ii).] Photographic blue print paper and cloth is sensitized by means of a solution containing a ferric salt, preferably a double salt, e.g. ferric ammonium oxalate, and a ferrocyanide together with buffer salts in neutral or alkaline condition. Suitable buffer salts are alkaline oxalates, citrates or tartrates to which may be added alkalies such as borax or ammonia or a slight quantity of sodium hydroxide. A ferricyanide may also be added. In a modification, the paper or cloth is first treated with a solution of buffer salts with or without the addition of alkali or wetting agents and is then sensitized with a solution containing the ferric salt and ferrocyanide alone or mixed with ferricyanide and any balance of buffer salts. In an example, paper is sensitized with a solution containing ferric ammonium oxalate, borax, potassium ferrocyanide and ferricyanide, and potassium oxalate ; the solution being applied by rollers. According to a further example, the paper is pretreated by coating with a solution containing potassium oxalate and sulphonated lauryl alcohol and, after drying, the coated side is further coated with a solution containing ferric ammonium oxalate, borax, potassium ferrocyanide and ferricyanide, and potassium oxalate. When concentrated solutions are employed, the temperature is regulated to prevent crystallization. The sensitizing solution may contain wetting agents, e.g. cyclohexanol, methyl-cyclohexanol, or sulphonated lauryl alcohol or ocenol.
