Title: Improvements in and relating to devices for recording the consumption of meters
IPC: G01D4/00
Filed: 1958-02-06
Abstract: 852,081. Recording-apparatus; magnetic record cards. OFFICINE GALILEO S.p.A. Feb. 6, 1958 [Feb. 11, 1957], No. 3966/58. Classes 106 (1) and 106 (4). In an electricity, gas or water meter consumption is registered by the position, form or strength of magnetized zones on a magnetizable card 37. Counter wheels 2 each have a cam 1 rotating therewith for limiting upward movement of a corresponding feeler 3 during recording. To initiate recording, a handle 39 is turned to raise rods 26 (a) causing a pawl 32 to align and temporarily hold the wheels of the counting train, (b) raising a transverse bar 29 clear of the row of levers 4 and (c) lifting the levers 4 until each is stopped individually by its feeler 3 engaging a cam 1. The digits registered by the wheels 2 determine the angular setting of the cams 1 and their radii, where engaged by the feelers 3, determine the strokes of the levers 4, which, through racks 7, 8 determine the vertical distances moved by magnetic heads 33 now positioned close to the card 37 upon which they impress magnetic zones of length proportional to the digits. If the heads 33 are brought close to the card only toward the end of their vertical travel, small zones will represent the digits by their position relative to the edge of the card. The heads 33 employ permanent magnets, but in the embodiment of Fig. 7 (not shown) an electromagnet is used, the heads being permanently close to the card and their common exciting coil being energized during, or only at the end of, the upward stroke, to cause recording. Alternatively, the degree of magnetization can be controlled by the extent of the scanning strokes.

Title: A process for producing alcohols
IPC: C07C31/02
Filed: 1966-01-28
Abstract: Production of alcohols from the by-products of the oxidation of aluminium alkoxides by separating from the alkoxides oxygen-containing by-products comprising aldehydes and esters and hydrogenating said by-products to produce one or more alcohols. The process may be carried out by first flash distilling by-products comprising aldehydes, esters, alcohols and hydrocarbons from the alkoxide and then (1) separating either (a) the aldehydes, esters and alcohols from the hydrocarbons or (b) the aldehydes and alcohols from the hydrocarbons and esters by extraction prior to hydrogenation; (2) hydrogenating the flash distilled by-products as defined above to convert the aldehydes and esters to alcohols and olefinic hydrocarbons to paraffinic hydrocarbons and thereafter separating the alcohols by absorption or extraction; or (3) flash distilling the by-products further to separate the aldehydes, alcohols and hydrocarbons from the esters and subsequently separating the aldehydes and alcohols from the hydrocarbons by absorption or extraction prior to hydrogenation. The separation of the alcohols; the alcohols and aldehydes; or the alcohols, aldehydes and esters from the hydrocarbons may be effected by absorption, at 70-125 DEG F. at 10-100 p.s.i.g., of the oxygenated materials on specified absorbents, preferably silica gel, from which any excess hydrocarbons are removed with a hydrocarbon more volatile than the absorbed materials and from which the absorbed materials are eluted with an alcohol, particularly methanol.  The separation of the alcohols or the alcohols and aldehydes from the hydrocarbons may be effected by an extraction in which there is employed a counter-current flow of wet methyl alcohol and a hydrocarbon, e.g. a mixture of paraffin hydrocarbons of specified density and boiling point, having a density different to the alcohols or the alcohols and aldehydes to be separated.  The hydrogenations may be carried out in the presence of specified conventional catalysts which include zinc chromite, copper chromite or barium promoted copper chromite or mixtures thereof either at 2000 to 3500 p.s.i.g. and 200-300 DEG  C. when esters or mixtures containing esters optionally in association with aldehydes are reduced or at 500 p.s.i.g. or 125 DEG  C. when aldehydes are reduced.  Dodecyl alcohol and mixtures of primary C8, C10, C12, C14 and C16 alcohols are prepared from by-products obtained in the oxidation of the corresponding trialkyl aluminium compounds.

Abstract: 621,417. Pneumatic guns. LAWRENCE, A., and LASZLO, S. E. Feb. 13, 1947, No. 4221. Convention date, Feb. 28, 1946. [Class 119] In a pneumatic gun of the type in which the barrel is mounted inside the barrel housing, the piston sweeping the space between the barrel housing and the barrel itself, cocking of the gun is effected by pivoting the barrel housing at its forward end so that the piston is moved forwardly by a lever to compress the operating spring. Referring to Fig. 1 and 2, pivoting of the barrel chamber 22 containing the barrel 20 about the pivot 14 at the forward end of the frame causes the piston 26 to be drawn forward by means of a lever 88 which is pivoted at its lower end at the pin 90 and at its upper to a hook member 80 sliding in a groove 82 in the barrel. This hook member engages a forwardly extending sleeve 28 attached to the piston head proper 26. A spring 32 mounted forwardly of the piston is thereby compressed until the piston head 26 is engaged by the nose of the spring-loaded sear 57, this sear forming part of the trigger mechanism of Specification 621,463. The construction of the lever and hook is such that the point of engagement of the hook and the lever pivots are maintained substantially in line during the cocking movement, as in Specification 621,461. Locking of the barrel chamber to the frame when in position for firing is effected by means of a hook 66, Fig. 3, carried on the barrel chamber engaging in two loosely interconnected tongues 100 and 100a (hidden by 100), sliding on pins 90 and 67, these tongues being released by a button (not shown).

Title: An improved method of proportioning the ingredients of mixtures by batches
IPC: C04B40/00
Filed: 1927-02-15
Abstract: 281,138. White, A. E., (Blaw-Knox Co.). Feb. 15, 1927. Concretes &c.-The quantity of stone to be mixed with a given quantity of mortar is determined from the volume of the voids. In making the mortar, the interstices in the sand are taken into account and cement and water are used sufficient in quantity to fill such interstices and provide an excess sufficient for workability. Similarly with regard to the stone, the voids are determined and to a fixed quantity of mortar a quantity of stone is apportioned such that the voids will be filled and a workable excess of mortar allowed. From samples of the stone the specific gravity, and the maximum percentage of voids likely to occur may be determined, and thence the smallest volume of stone that may be used with a batch of mortar is calculated. The weight of this volume is then taken, and compared with the weights of similar volumes of actual quantities to be mixed, The voids in these quantities may then be determined, and the total volume of stone to be used with the batch of mortar adjusted. Charts or schedules may be prepared indicating the amount of stone to be added according to the weight of the standard volume of stone.
